Ask HN: What Are You Working On? (Nov 2025)
by david927
What are you working on? Any new ideas that you're thinking about?
I recently launched a daily word puzzle!
It’s inspired by tile placement board games like Patchwork and crosswords. You rotate and move tiles to rebuild a broken crossword.
It’s free, web based, and responsive.
I currently have several hundred daily players and growing. My wife and I create the puzzles and I’m continuing to fix bugs and add new features.
I just launched a ”community puzzle” feature to let players help build new puzzles.
I’d love to know what you think!
With all my heart, I want to cheer you on. Making stuff is damn hard, and shipping is even harder. You did that, and I applaud you for it.
I do a lot of NYT puzzle stuff every day and some other random puzzle sites before I get out of bed. That said, I'm over 40, love puzzles, love complicated board games, went through your brief explainer, and could not get a sensible handle on how to even start this thing. A new player has to really care about how to even try to begin to figure out whatever this is. I gave it about 20 seconds after the "how does it work?" Honestly, I gave up. I'm really not trying to rain on your parade. You might find a niche audience, and it'll be what you're going for, but I think you need a much, much better rules explainer if you want to be even remotely in the vicinity of a Wordle-level banger.
This thing might be really awesome, but not being able to figure out how to use it is a hard out for me.
Hey, thanks for the candid feedback! It’s super helpful.
I’m curious if there were specific aspects you struggled with or if the whole thing was confusing?
Did you try the Practice Puzzle or jump right into the daily?
Practice puzzle: https://tiledwords.com/puzzles/practice
It sounds like you read the instructions but they weren’t enough. Maybe a video explainer would be better? Does the gameplay recording on this Reddit post help at all?
https://www.reddit.com/r/DestroyMyGame/comments/1osxb2q/i_re...
People really seem to like it once it clicks (Over 1100 people have finished the daily puzzle so far today) but there is a steep learning curve and I’d love to learn how to help people get past that initial hump.
IMO I shouldn't change the onboarding much. The game is very intuitive. Everyone I showed it to has picked it up in about 30 seconds.
It's very much a learn-by-doing game.
PS - This game is so fun. I don't usually do word games, but I can't stop playing this one.
Thanks, that’s good to hear!
My ideas are:
- Add an optional video explainer on the How To Play screen
- Redesign How to Play to push you towards the practice puzzle more strongly
- Add more practice puzzles that ramp up in difficulty
That was a fun little game! The hinting felt appropriate, only thing I didn't really like was that it got a bit "cramped" towards the end moving things around. Will try it again tomorrow. :)
Thanks! Yeah it’s tricky since I wanted to make it work the same on small phone screens as large computer screens, so the place is limited.
I want to explore a future feature where dropping a tile “pushes” other tiles out of the way that will hopefully make it feel less cramped
There are not many sites I whitelist for javascript, or even bookmark these day. Really glad I tried your game, it's fun and nicely executed. Well done to you both.
Thanks!
Good fun. I discovered a big though. I could not yet reproduce it, but I managed to somehow have letters glitch out of the Tetris shapes they are in. When I move the tiles or rotate them, the letters are back where they should be. So it's not game breaking, but seems to happen in some case. At first I suspected, that it was because my phone was locked in between, but I tried that and when locking it manually, that bug did not happen. So no idea, sorry!
Ahh dang I’ve had a few people report this but I haven’t been able to reproduce it. I think it does have something to do with locking your screen and coming back but I haven’t figured it out yet
I received a call during the game and it happened too. Twice actually :)
Interesting, I’ll have to try that to see if I can reproduce it, thanks!
This is really fun — have you played with making the tile position opinionated (not agnostic)?
i wonder if have the clues point to a starting square (e.g., "E5") would be better than the current "reveal" aid. The spatial information would become more helpful toward the end when the player is dealing with the words they need help on.
Could you expand on what you mean about opinionated vs agnostic? It sounds interesting but I’m not sure I follow.
I like that clue idea! I want to change how the reveals work. I’ll play with that!
Really great! One of the things that Wordle did that I thought was very clever was having a copy and paste social media preview of how you did. It might be worth adding that for vitality... you could even add an image preview with Open Graph meta tags if you were clever.
Thanks, yeah I’d like to improve this. There is a “share” option when you complete a level but I don’t think it works as well as Wordle’s in terms of storytelling.
Generating a custom sharing image is interesting!
This is something I've gone and forth on for https://threeemojis.com/ as well. I think it's pretty hard to generate a story of a complicated puzzle, in part because the person you are sending it to doesn't have an idea of the terrain you were playing on and so kind of doesn't care. I do see some people doing custom share images with their puzzles, but it doesn't seem to have caught on so much.
* virality :-/
Nice! Some feedback from my wife, who is into all manner of word games: she found it a little bit brute-forcey: needing to try all different combinations in order to get the right configuration of the word. In contrast to a crossword where there is already a layout, which gives her a hint for how to proceed with the rest.
(She finished today's puzzle, and I gave up.) From a UI perspective it is very slick - very smooth, and I like how it kind of "gets" what you were trying to do when providing corrections/hints.
>In contrast to a crossword
there's a type of crossword called "diagramless" where you have the numbered clues and an empty grid
there was one in NYTimes Magazine Sunday puzzle page this past weekend
Thats great feedback, thank you!
Man, this is absolutely awesome. This has the feeling of being the next wordle or a similar quick hit type game. Really impressive.
Thanks!
This is really well made! As someone who has built daily puzzle games (ex. sidewords.ca, kickoffleague.com, and just today fivefold.ca), I appreciate the effort it takes to make something that polished! It plays really well on mobile, which is tricky, especially when you’ve got a grid as big as yours.
Thanks, I’ll have to try out your games! Any tips or recommendations you’ve learned from your puzzles?
Hah well one tip would be do NOT make a complex framing/structure for your daily puzzle game like we did with Kickoff League. It was a fun experiment but it mostly just confused people.
A more meta tip is if you make multiple games, try to have some genre or theme overlap so you can build a community among players of your games. I wish I had done this more with my more successful games (which are mobile games, not web games, but the same idea applies).
That makes sense, thanks!
I saw your Show HN post a few weeks ago! Really appreciate the smoothness of your UI and the simplicity of your onboarding, I see how much you have dialed in. I've been working on a daily puzzle game too (it's getting there...), maybe you'd enjoy it https://slab17.com/
Slab 17 is a really interesting and unique puzzle! I love the act of slab creation. It’s very satisfying and the aesthetics are great.
I found the instruction about double tapping a little confusing at first but figured it out as I played.
Nice work!
Thanks for the note and the feedback about the instructions! Got me to rework the wording.
Very cool!
I solved the first puzzle: -Congratulations! -You solved Paprika with 18 slabs
But this was unclear: -You've solved 0 puzzles! -Reveal Rule -Next Puzzle -View Archive -You still have 2 guesses left. Finish guessing before revealing the rule if you're feeling brave!
I have to do 2 more guesses before I can reveal the rule that I already figured out?
Thanks for the note! This part needs work and I really appreciate the call out. I'll try to explain here to share, and maybe clarify my own thinking.
Getting any of the guesses right counts as a win, and you get different guessing slabs for each guess (this latter part isn't made at all clear upfront).
If you have a rule in your head like "no red", but the true rule is "no red or orange", it's possible that on the guessing slabs those two rules evaluate to the same things (e.g. there weren't any oranges present in the guessing slabs). You could then try the rest of the guessing slabs, which might have an example where you get it wrong, giving more gameplay.
I wanted to give a victory on any subset of 5 slabs guessed successfully since trying to get all the guesses is very hard (especially the first guess on many puzzles), and you can get new information from guesses which fail, which offers some progression. Hence getting "you won" and the ability to reveal the rule (I've also thought about keeping the reveal unavailable until you do all guesses) and the invitation to keep playing.
If you have a minute I'd love to hear from you if that makes sense and if you have thoughts about what might make more sense. I've also tried to consider ways of restructuring the gameplay, e.g. automatically progressing to the next set of guessing slabs, such that the flow here is less confusing.
Thanks for playing, and for sharing!
That makes sense.
Maybe just simply state it?
E.g, instead of “you solved paprika”:
“You got 5 slabs right; 10 more to prove you really solved the rule”
(Being better versed in making games than I am, you can likely come up with more enticing prose)
Appreciate the reply, this is simpler than my thinking and I like it!
The animations in the interface make it feel more "jelly" and not "wooden" like a number of other such interfaces.
Thanks! I spent a long time trying to make the core controls feel intuitive and natural to use
The amount of care you put into it must be massive; a noticed so many nice subtle details that make interacting with the pieces easy and fun. Kudos!
This is a lovely game!
This game was Show HNed two times in ten days, [1][2], but unfortunately, it didn't get as much attention as it should! Ironically, this current thread has already gained almost double the comments from both submissions combined!
I whish you best of luck to succeed in your journey.

Thanks!
Yeah I felt odd reposting the Show HN but I thought that the HN crowd would enjoy the game if a post got traction
You can email mods and ask to bump up a Show HN post if it has merit. Even if it's your own.
I’m enjoying this a lot and even got my partner playing. We did one together and now they are off working through puzzles because they liked it so much.
The game design is really good too. It has just the right amount of juice.
Thanks for the kind words and sharing it with your partner!
This puzzle is genius.The interface is minimal and user-friendly, everything feels smooth and intuitive.
Nice! What might be a nice lesser 'clue' to simply revealing a word is highlighting letter(s) on the board that are part of it? Favouring maybe highlighting letters that are contiguous with a blue bit?
Yeah that’s a good idea!
This is really great. Played this for quite a long time, nicely done!
Thanks! Hopefully you enjoy the upcoming daily puzzles!
I really enjoyed this! wondering about a possible "scratch" section or larger area - found myself spending a lot of time moving pieces around to get enough space
Yeah I’ve gone back and forth on this.
On large screens adding more space would be a big quality of life improvement.
But it doesn’t really work on smaller screens.
So far I’ve tried to keep the experience as similar as possible across devices but maybe that’s silly
Yeah, I think you should be actively encouraging the sales of laptops/desktops.
You had me at Patchwork. This is super fun. Thanks for making it!
I love Patchwork! One of my wife and I's favorite, easy, go-to games.
Nicely done! Played two puzzles and had a blast! Works awesome on mobile
Your website grew to several thousand UVs per month in just two months — that’s impressive!
Beautiful UI and a genuinely fun game
Thanks!
That's awesome!! It took 15 min and I gave up on some words.
As a non native it feels awesome to finish a puzzle like this haha
Nice job! I’m glad you enjoyed it!
It was super fun! Would love a little more space to move pieces around but otherwise fantastic job!
I shared with people. They loved it.
Thank you!
And those people have shared it to their friends. At least in my part of the woods, you have a hit.
Thanks, that’s lovely to hear!
Did you do a Show HN thread on this? Do it so I can 'favorite' it please
You can favourite comments. But yes, there was a Show HN.
This is really good. I like the idea of the game and your execution of it is superb.
Nice job, I enjoyed it, I’ll play again tomorrow!
Very neat and clean UX, kudos to that!
How do you market it – now or planning to, if I may ask?
Great question… marketing is not my strong suit.
I showcased at the Portland Retro Gaming Expo with the Portland Indie Game squad and that got me some players. I also shared it on my various personal social medias. The neighborhood board game store let me put up a poster!
I’m also hoping that organic sharing will drive growth.
This HN comment has been some of my most successful marketing so far. Around 2400 people from HN have visited since I posted!
The game deserves it. As a non-native some of the things are tough without "cheating" but its still fun. Didn't check but do you also support other languages besides English? (In Estonian for example we have some tricky vovels: üöäõ, which might throw some code haywire)
I _think_ the code would support it fine but I’d have to check. For now all of the clues are in English
I love it. I struggle more than I want to admit, but super fun nonetheless.
It definitely has a bit of a learning curve! In playtesting it sometimes took a bit for the rotation to “click” for people.
Yeah that was it for me, the rotation really threw me off.
Wow that is a clean and responsive interface! It feels great on mobile.
Awesome game! I've been looking for something like this.
Thanks, I’m glad you like it!
That was quite fun. Will be back.
Super fin idea, very nicely executed, thanks!
That was wonderful, I'll be back tomorrow.
Thanks, I’m glad you like it!
Just played it, really super. Great job.
this is very cool, noticed vue and nuxt nice.
Thanks! Yeah I love Vue and Nuxt. They worked great for this project
Just solved a puzzle, nice project!
Fun game! Shared with some friends :)
Thanks!
I also enjoyed this, great work!
Amazing game, perfect for me.
Very nice game, good job!
This is a really fantastic game. I’m a big fan of word games, especially crosswords and scrabble/words with friends so this is exactly “in my q zone”.
I hope you make a success of this and sell it to the NYT for a disgusting amount of money.
That was fun, I’m in!
Awesome!
very addictive and original puzzle game, like it!
This is bloody good
Great game! The effort you put into animations and interactivity really pays off, especially when first learning how the game works.
This is a classic HN comment but I’d love a Thursday/Friday crossword difficulty equivalent in addition to the dailies which are a ~Monday.
Thanks! I would like to explore different difficulty puzzles in the future!
Really nice
Awesome work
I love it!
this is great man
Continuing with my retro productivity software blog, Stone Tools: https://stonetools.ghost.io
I was getting a little bored of retrocomputing discourse being so centered on gaming, so I'm exploring the productivity software of the 8/16-bit era. I put real effort into learning and using the programs, giving my light-hearted but heartfelt assessment of its form and function for both its time and today.
Using the software inevitably gets me thinking about other things, and I explore those threads as well. For example, "Superbase on the C64" also discusses the legacy and promise of "the paperless office." A couple of other posts got some nice traction here on HN, notably "Deluxe Paint on the Amiga" and "VisiCalc on the Apple 2".
I'm hoping to build a strong monthly readership, so I'm putting in the work. It's been up for two months and five posts now, with a new one coming at the end of this week.
I think this software archaeology / history-keeping is really important. Keep up the good work. These paragraphs resonate with me:
> There is utility in those old tools and interesting ideas to be mined. Recently I stumbled across something that by all accounts should have set the world on fire, but whose ideas needed more time to germinate before blossoming much later. Discoveries like this are not just nostalgic “what ifs” to opine wistfully upon, they can be dormant seeds of the future.
> Computing moves at such an unrelenting pace, those seeds may lie dormant for any number of reasons: bad marketing, released on a dying platform, too expensive, or even too large a mental leap for the public to “get” at the time. I see this blog as a way to explore the history of the work tools we use every day. I don’t do this out of misty-eyed sentimentality, but rather pragmatic curiosity. The past isn’t sacred, but it is still useful.
What's your research process? Do you use lots of Internet Archive material? Do you reference any personal artifacts i.e. old hardware or documentation laying around? Any interviewing?
Thanks for the kind feedback, and I'm happy you felt resonance with those words. I use tons of Internet Archive material, but also stuff from various retro enthusiast sites which focus on specific hardware platforms. Lots of books, I look through YouTube for interviews, and include my own personal history with the machines and genres (I don't want the blog to read like a passionless how-to manual). If I had the physical space for a hardware collection I'd do that, but alas. No interviewing of my own, just research into existing interviews up to present day. The main point is really to let the software speak for itself and see if it and I can be friends.
That's interesting. I agree that outside of gaming you really don't see much being done with the old systems.
My first job out of college was with a tiny, now-defunct company that built simple I/O hardware for 8-bit systems. One of the "side products" was a MacPaint clone for the Radio Shack Color Computer II called CoCoMax. We didn't write it: AFAIK, the programmer for the original version contacted the company and asked if they wanted to buy it and pay him royalties. He later went off and built an even more successful product used in TV stations called the Video Toaster. Side product or not, CoCoMax was a cash cow!
On the heels of that success, another programmer who'd written a more advanced version for the Color Computer 3 offered the same deal. From what I recall, they both made buttloads of money from their royalties.
Sometimes I wish I had kept some of that old hardware & software, but it's long gone.
Your website is amazing! I've being complaining recently to some coworkers that current software is often bloated, full of things that are only distractions and due to all the accidental complexity, full of bugs and slow. One day, at work, Gnome stopped working due to some javascript issue and KDE at home due to something similar (I guess) and as I had to get some stuff done, I just installed WindowMaker and started using it. I forgot how amazing it was and how much it just work. Some customisations I do such as changing Caps to Control and other similar things were easy - just dealing with xinput/setxkbmap, etc.
So, my impression is that, for a while, things started getting simpler by having WYSIWYG editors and multiple things running at the same time in windows, but as the processing power and memory started improving, instead of making things easier and better, we (as people) started just adding more features and other things that they just made things more complicated than they should be.
Well, with all that, I wish success for you!
PS: It would be great if you had RSS support on your website.
This is a neat project! I read the last post and I’ll work my way back through them.
Thanks, I hope you enjoy the series!
This is super cool. If it was RSS enabled I'd immediately add it to my feed!
Thanks! I don't actually know anything about how Ghost blogging platform interacts with RSS feeds, but I get a small amount of traffic from personal aggregation services. I guess I kind of thought RSS is enabled, but I don't use it so I honestly don't know. I'll look into it and see if there's some setting or toggle switch somewhere I need to flip.
That worked for you? I was having a devil of a time getting Feedreader to bring in that feed. I also had never touched Feedreader until last night and might have done something dumb. Inoreader did bring in the feed, but only after I "tricked it" (?) by doing a search for the feed; it wouldn't accept the rss URL. It all felt very mysterious and opaque.
I got word in the Ghost forums that there may also be an RSS feed bug, which I'll look into and see if that applies to this case.
It worked in NetNewsWire, a macOS feedreader.
RSS is a bit of a pain as most feed readers will accept malformed XML (unlike Atom feeds). Hence you end up with a lot of malformed XML.
Having said that it mostly looks valid:

Great to know, thank you for the investigation.
That sounds fascinating, thank you for this research.
My pleasure!
A tool for creating custom Tailwind-style color palettes for web and UI design that pass WCAG contrast requirements:
https://www.inclusivecolors.com/
The interface is optimized to let you quickly explore and tweak multiple tints/shades at once so you can customize all colors exactly how you want e.g. try dragging vertically through the saturation curve in one motion to edit all the tints/shades at once, or shift whole curves horizontally by dragging between the dots on a curve.
It uses the HSLuv color space, where (unlike say HSL) the WCAG contrast stays the same when you change the hue and saturation sliders. This makes it much easier to explore accessible colors choices as you know only changes to the lightness slider will impact the contrast. You can also switch from the WCAG2 contrast checker to using APCA, which is meant to correct for inaccuracies in WCAG2, such as it being too forgiving for dark mode color combos.
Note the mobile version is more of a preview and the desktop version has more features.
I probably need to add something like a tutorial as there's a lot going on, but I've added more hints and tooltips recently. Open to feedback on what's initially confusing and what changes might help!
I passed this on to some accessibility folks at a couple conferences in the last month - everyone was impressed :)
That's awesome, thanks!
I'd also keen to hear from people who are interested in accessibility but don't know much about it too. I've tried to explain the WCAG contrast rules in the simplest way I can (interactively, via the live mockup example on the right and contrast indicator icons that appear on the left) but there's quite a lot to cover.

bookmarked! Cool work!
Currently working on a take on Pokémon GO + Pokémon Snap but for birding. The goal is to explore your neighborhood, find birds, take good photos of them all. Next month, I'll be doing an event to find a rare bird, excited to see how it goes!
It's still a small closed alpha, if anyone is interested: https://testers.birdlego.com
Here is a rough trailer of it: https://www.youtube.com/watch?v=yVpR8aafFjI
I got super excited thinking this was for real birds. I would love someone to gamify birding.
Not sure if this meets your criteria, yet iNaturalist [1] is kind of "gamified". Has a rather large "bird" taxon observation amount. 38,393,861 observations, 11,165 species, 1,130,700 observers, 188,988 identifiers (people who identify species from your pictures)
When Romania announced that the Lesser Kestrel had returned after 100 years iNaturalist actually had several of the observations in the nearby area. [2]
[1] https://www.inaturalist.org/observations?subview=map&taxon_i...
[2] https://www.inaturalist.org/observations?subview=map&taxon_i...
I guess it's not intensely gamified, but I have a couple friends at like 80-90% on Merlin. It's their excuse to travel and live abroad
This is actually exactly what I’ve been working on as a passion project for the last year and a half: https://apps.apple.com/us/app/wings-whistles/id6503321263
It’s basically a gamified version of Merlin. Would love any and all feedback!
Birdle Go seems really cool, very impressed and would love to test that!
Any chance you'll release an android version?
Yes! I’m aiming to release it by January at the latest. I’m using tflite rather than coreml so that the transition is easier.
What’s missing from eBird?
Certainly gamified a bit as I learned from:
LISTERS: A Glimpse Into Extreme Birdwatching
https://youtube.com/watch?v=zl-wAqplQAo
1.9m view | 2mo ago | 2hr long (buckle in, documentary by a couple young goofball brothers)
I want something more gamified. I want to go on missions or complete challenges or something. Not just identity and log stuff.
I'll think of ways to bridge the virtual world with the real world birding one. Let me know if you have any ideas for that :)
Oh I was hoping for this but with real birds in my neighborhood. Still neat!
Do you have any plans to provide this data to ornithological research groups? I know there's an annual event where people across the nation are encouraged to count the birds in their back yards and report it, so it seems like this kind of amateur birdspotting is valued in the scientific community.
I'd be careful with the name and the way you're describing it, as Nintendo are notoriously litigious. Best of luck with the project, though!

I would pay for this. 100%.
OK, I would pay for this. Definitely following!
What a good idea, sounds fun!
I’m working on a free and open-source invoice generator: https://easyinvoicepdf.com/?template=stripe
- No sign-up, works entirely in-browser
- Live PDF preview + instant download
- VAT EU support
- Shareable invoice links
- Multi-language (10+) & multi-currency
- Multiple templates (incl. Stripe-style)
- Mobile-friendly
GitHub: https://github.com/VladSez/easy-invoice-pdf
Would love feedback, contributions, or ideas for other templates/features.
PS: e-invoice support coming soon
Ha! I built a similar service for quote generation a couple of month ago: https://quotemachine.cc
No signups, free for all, browser-only, live pdfs, etc
Built it for a friend and decided to share with all, it's just a react app (no backend) running on GCP and costs almost nothing to run.
Didn't think about opensourcing it and I will, why not.
Looking good =)
Nice work. I liked the instant pdf viewer. Kudos for your efforts.
Only thing I would suggest is, to support different tax formats (or provide an ability to fill custom tax format name that applies to the whole invoice). Right now, it is largely VAT. In some countries, it may not be relevant.
(Having said that, as a work around, currently anyone can use Notes field to fill custom tax details and hide all VAT related fields.)
Thanks for the feedback, will take a look into supporting custom tax formats
UPD: Created an issue to investigate

Hey, that's actually really useful! That's so cool!
Thank you
I think by this point everyone that is learning a language knows that immersion is very important, however a problem I've had myself is that the content that interests me is beyond my reach, and the content that is within reach doesn't interest me.
This is my attempt at doing something to remediate that. You select the content you want, and I create a personalized study plan to learn the most important words to achieve a target % of understanding. Then I generate a short story each week for your particular level containing the new words in the context of your content.
The idea is to bring the content you want to learn to your level so you can watch what you want to watch.
That's a great idea, and I live the UI! I wish I have some time now to learn Japanese now...
I'm making Easel, a 2D game programming language designed to match how humans, not computers, think about game logic. It also has automatic multiplayer. I've been working on it for 3 years!
Easel feels like a declarative programming language even though it is imperative, because lots of useful game-oriented features are first class. Like behaviours - you just say `on Pointer { ... }` and you have a concurrently-executing coroutine that's lifetime is managed. But you don't think about any of that complexity, you just think of your entity as having a behaviour and go forth and make your game.
It also happens to have automatic multiplayer. Normally with multiplayer you have to worry about doing everything in a "multiplayer safe" way (i.e. be deterministic and only modify the things your side has authority over). My idea was to put all the multiplayer stuff in the programming language itself, underneath all your lines of code. This way, anything you write in that programming language can just be made multiplayer, automatically. So you can just pretend all your players are in one shared world, like a singleplayer game, and the engine does all the multiplayer for you. It was really difficult to make but it makes multiplayer so easy for you now.
Easel is my idea of how games should be made, or at least as close to the idea as I can achieve with 3 years of work, and I would love for more people to try it out.
> you can just pretend all your players are in one shared world, like a singleplayer game, and the engine does all the multiplayer for you
But how does this really work? The website also says it's just baked into the language but there are many different approaches to networking games that have their own pros and cons.
It uses rollback netcode. The inputs are relayed to the other players and executed on all clients, and they end up in the same state because all Easel programs are guaranteed deterministic. To hide latency, the clients simulate forward even before they have received all inputs, and once inputs have been received it rolls back to the point of divergence to correct the prediction error. This works because the prediction is correct most of the time.
To be able to roll back, Easel incrementally snapshots the game state every tick. It only snapshots (and restores) what has changed, which makes it a lot more efficient than most rollback netcode implementations.
It also uses a peer-to-peer relay and adapts the latency asymmetrically, so the player who introduces latency feels their own latency.
I know there are other models and pros and cons, this is the right choice for Easel because I wanted to make the multiplayer fully automatic. One shared world, coded like a singleplayer game. There are certainly games which suit a client/server model better but I think the developer would then need to understand where their code is running and when to do remote procedure calls, and my goal was to make multiplayer so easy that even a teenager on their first day of coding could do it.
That's great stuff! IIRC Factorio takes the same approach but relies on extensive testing to avoid running into desync issues with non-deterministic code. Would be very cool to be able to build games like that without needing to worry about desyncs!
It might be a good idea to highlight some of the limitations to this approach somewhere so users aren't caught off guard later in the development process. For example, it wouldn't be great to build a competitive FPS or MOBA with this because the game state is replicated to all players which is a cheaters dream. The latency characteristics would also not be ideal for games with a larger number of players. I also assume there are no escape hatches for doing any non-deterministic things like I/O so there would be limited to no persistence possible. It won't be an issue for most games but worth highlighting just in case IMO.
Yes, I should have a "who is this not for" section somewhere, that's fair enough.
Persistence is actually handled by the server, and then the server inserts an input back into the game state with the result when it's done. So, no issue with I/O.
I see Factorio is doing deterministic lockstep, which like rollback netcode but without the rollback. That makes sense seeing as it is a game with a lot of state and so it would be too expensive to snapshot and rollback all the time. But yes, I think having a game engine which guarantees determinism in all cases could be a useful base for other multiplayer architectures too. Right now Easel only does rollback but maybe it could do more in the future.
This is really cool. Nice project!
I tried doing something much more rudimentary before. Will be following
Oh, thank you!
I would love to hear more about what you were trying to do with your project before. Was it more similar to the declarative coding part, the automatic multiplayer part, or something else? Part of why I'm doing this is to explore the design space of how games should be made and I'm interested to hear what problems, issues, pet peeves, "bugbears" etc that other people think are worth solving.
It's been a while. But I believe what caused me the most headache while trying to build something like this was handling the interactions between different elements. Declaring which objects were affected by "attacks" or could be "player interactive" or "affected by player but not by NPC". Really this boiled down to proper inheritance. But I found myself so deep and tangled a fresh reset would have been better. Then determining if the object itself or an "objective manager" should perform the calculation each cycle.. etc
It was messy. I ended up having NPC, Item, Attack classes and for each a NPC Manager, Item Manager, and Attack Manager to calculate all their interactions and states.
That's why your project seems interesting because it seems to handle the heavy lifting of behaviors and "behind the scenes".
Oh yes, handling interactions and dependencies and what is affected by what. I did a lot of React development (as in the frontend web framework) before making Easel and was quite inspired by how it hooks to change. The way you give it a little routine, it says what it depends on, and then it just fully re-executes that whole routine when the dependencies change. So in Easel when you say `with Health { ... }` it makes a behaviour that re-executes every time the Health changes. But, if it just reran the behaviour, then you'd end up with it adding a new sprite (for example) every time it re-executes, until you've got hundreds of them. So the other trick is the Easel compiler assigns an implicit ID to things like sprites so that it will replace rather than add the second time around. It's built into the programming language so you don't see it (most of the time). It actually took me 2 years to come up with that, which is both cool and depressing when I can explain it in one paragraph.
> So the other trick is the Easel compiler assigns an implicit ID to things like sprites so that it will replace rather than add the second time around
Is the ID computed based on the shape of the expression at runtime or on something else?
I found https://easel.games/docs/learn/language/functions/ids#implic... which suggests they are structure-based, at least, though loops aren't mentioned.
Great documentation, by the by!
The implicit ID is just an auto-incremented number actually, it's not anything too special. That means, if you have a loop, the component has the same ID each time and gets replaced. That is a feature, not a bug. So this code snippet will keep replacing the text sprite with a new one, counting from 1 to 10:
for i in RangeInclusive(1, 10) { TextSprite(i) }
Yes, you found the right place in the documentation. Thanks, yes I worked very hard on the documentation!
Ah, so you don't do parallel with implicit IDs right now, I'm guessing. Or you do, but it has some interesting bugs as the IDs shift around? Or the scope of the auto-incrementing number is lower than "the entire program" so parallel works?
It sounds like you are asking, if auto-incrementing IDs are assigned in parallel at runtime, then order of execution of the threads must affect which ID gets assigned to what, and that must make some interesting bugs?
The IDs are assigned at compile time by the Easel compiler. So they don’t change in any way at runtime. Does that answer your question?
Mostly - if the IDs are assigned at compile time, how do you deal with _runtime_ locations like "the fifth iteration of a For loop"?
Actually, all iterations of the for loop have the same ID. This is the design. So the second iteration has the same ID as the first iteration, which means it replaces the sprite created by the first. The fifth iteration has the same ID as the fourth iteration, so it replaces the sprite. So all the iterations keep replacing the same sprite. And that is how you animate sprites!
If you are actually trying to make multiple sprites and not keep replacing them, what you do is you spawn a new entity to hold your extra sprite:
for i in Range(0,10) { Subspawn { TextSprite(i) } }
That code creates 10 sprites and achieves what I think you are thinking of.
I've actually just recently been through this myself. I'm also building something for kids to build games in. But much more opinionated than Easel. It's interesting to me that Easel looks declarative but is imperative.
I've actually gone with a 100% declarative approach. Basically you define effects, which are executed in response to certain interactions. There's a comprehensive targeting system. But the best part is this is all type-safe using TypeScript, the declarative structure is enforced. That means even when you chain effects, nested effects are able to access (incl. autocomplete) the targets of parent effects etc. Whilst this provides a super nice experience to consume, it's definitely non-trivial to build this system.
Wow, impressive project! I like how you’ve focused on tooling and workflow, it makes sense that is where your most important problems are. Cool QR code drawing template idea too :)
I've been working on a 3D voxel-based game engine for like 10 years in my spare time. At this point it's getting pretty close to being shadertoy for voxels.
https://github.com/scallyw4g/bonsai
I recently ported the terrain generators to the GPU, and increased the visible volume to 1 billion voxels cubed. I did a short YouTube video about it.
https://www.youtube.com/watch?v=bLfgjWsM1PI
I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.
Awesome, looking forward to use this. What was the hardest part of this project? What motivated you to attempt creating this?
> Awesome, looking forward to use this
Stoked to have another user!
> What was the hardest part of this project?
Fuck.. that's a hard question. I'm almost always trying to push at least one of three boundaries; voxel engine techniques, engine performance, my mechanical programming skill. Trying to push those boundaries, often in tandem or tridem, is always hard. Different jobs are often hard for different reasons, but overall it's been a difficult project for most of it's existence. That said, doing hard projects is what I enjoy, and it's a great feeling when you sit down to, for example, optimize something, and end up making it 20x faster!
> What motivated you to attempt creating this?
It started out as a learning exercise; a safe space where I could just 'fuck around and find out'. When I started, I never expected to spend nearly as much time on it as I have.
FreeBSD 15.0. Rather depressingly, almost everything I said two months ago is still true: https://news.ycombinator.com/item?id=45419134
But I'm hoping to have it out by the first week of December.
Thank you for your hard work. I don’t have a lot of time right now but would love to try to contribute to FreeBSD early next year
Thanks for all your hard work!
It's an explorable database of films, TV shows, books and board games based around their historical setting: where and when the thing is set. It's been incredibly complex and interesting getting the (messy) data, making sense of it and trying to design a UI to explore it.
https://stevebennett.me/2025/08/26/whenever-exploring-times-...
This is totally cool!
I will note that there are some Norfolk England things showing in Norfolk Virginia.
Thanks, yeah, it's a hard problem.
It would be interesting to see for movies and tv series where it’s set vs where it’s actually shot
This reminded me instantly of Every Frame a Painting's video "Vancouver never plays itself"[0].
Yeah, that's a whole different thing. I saw this map once that showed places in California and how they were used to film various locations around the world. Turns out LA is very well situated.
Great job! I just went down a rabbit-hole exploring some historical events
I’ve been working on https://canine.sh which is a free, open source Heroku alternative for 2 years now.
It’s exactly the product I wish I had when I started my previous company. Running on PaaS is incredible for devex but the pricing is bonkers, and the vendor lock in makes it really hard to deal with annual price increases. We spent close to 400k / year for just 128GB combined fleet in our last startup on Heroku.
Canine tries to get the best of both worlds: developer friendly PaaS with no lockin or price gouging.
Just added build packs as a build option recently.
Also got a sponsorship from the portainer folks which lets me work on this close to full time
Hoping this saves someone the headache I had two years ago.
Hey Chris, would love to chat about this - could you email me? Cheers
This looks really cool, will try it out!
Let me know how it works out! theres a discord link for any help, etc.
We have been building https://finbodhi.com/ a local-first browser app (PWA) for personal finance, based on double-entry accounting.
FinBodhi uses double entry so complicated set of transactions and accounts can be modeled (which happen often enough in users financial journey). We wrote about double-entry here: https://finbodhi.com/docs/understanding-double-entry
We do use online services like firebase for auth, and some service to fetch commodity prices etc. But all your financial data is on your system (we use sqlite over opfs, in browser). For synching across devices, that data is encrypted with your key before it leaves your device. You can backup the data locally (if you are using chrome) and/or to your dropbox. It's designed so that we (the people building it) can't access your data.
There are many more features, like multi-currency, visualizations, a sheet to use your data to do complex calculations like taxes, planning for your future etc.
Feel free to try it out with the demo account (no sign-in required). Note: app doesn't work in Firefox private mode.
Cool stuff, happy to see that you focus on local storage. How do you handle uploaded financial statements? Are they sent to 3p?
Import is done locally. No 3rd party is involved. We have build custom importer. e.g you can import a csv and map it's columns to what we need internally. We also allow some logic in importer. E.g. to figure if a row is credit or debit. etc. It should be feasible to import most csv statements. PDFs and Excels should also work, except for some complicated cases where a transaction is spread across multiple rows.
There are a few custom importers also, for indian context.
I'm seeing a lot more Firebase spoof spam emails recently in general, keep that in mind as a service if you rely on it for outbound comms
I've been enjoying the breadth of projects made possible with AI, I've cataloged over 200 of them created in 2025 here: https://jonathanclark.com/posts/ai-coding-million-lines-2025...
A few of my recent favorites: - swim lap counter in html/JS that uses the camera to watch you swim and count laps/timing - video recorder that records your window/desktop and uploads a file to S3 - video conferencing app that allows a 2 year to click on a family member face and initiates a video conference using webRTC, STUN, and browser audio/video capture with automatic bandwidth adjustments (works on all platforms with pure HTML/JS). - CUDA based ray tracer with HTML UI that can trace over 2m rays per second on my laptop for scientific study, allowing real-time display of optical parts. - chat front-end for image models like gemini-pro and openai that take other images and text as references and generate a big library of options to chose from in seconds, I've been using photoshop for decades but I tend to use this more now.
> CUDA based ray tracer with HTML UI
I'm curious if you mean they're running a raytracer on the back end, and you interact with an HTML UI, or if it runs browserside, maybe via WASM. AFAIK CUDA isn't directly compilable to WASM (yet?)
I have a node middleman that proxies request from an HTML/JS front end to a native cuda process using web sockets. To support multiple windows, the node process process provides communication between two browser windows. This lets me have render a model using 3JS in one window and a ray traced version in another window.
Woah that's a lot of projects. Would be cool if you could open-source some of them.
+1 to this, not all of them of course, but there's some very useful ones in there I could make use of.
Thanks for the encouragement. I do plan to make more of them open source, in the past it's been a bit of burden to document, test, and fix bugs before publishing but for some projects AI can do that for you now.
One project I did publish: https://github.com/jclarkcom/ble_proxy This turns your cell phone into a network proxy, but using BLE so the phone can be connected to a Wifi network (hotel, plane, etc). It's pretty slow, but in some cases you just need a little bit of data to work. I made it on a plane ride where my cellphone had data but my laptop didn't.
100% completely understood, making something you only intend yourself to see compared to something other people will see is very different.
Very cool! Love little things like this.
AI powered financial data PDF extractor sounds interesting
Porting Ruby to Fil-C
It's very interesting because the Ruby codebase uses a `typedef uintptr_t VALUE` type to mean any of the following:
- A pointer to the heap
- A Ruby tagged value (which may be a pointer to the heap)
- Any integer value that fits in `uintptr_t`
Fil-C doesn't allow you to carry around pointers using integers, in the sense that when you do that, the pointers lose their capabilities.
But in Ruby's case, it's not as simple as changing the typedef to a pointer type, since `VALUE` variables often end up being used for integer math (including bit math, shifts, etc).
So, it's going to take a nontrivial patch to Ruby to get it to work in Fil-C. I think I'm about 70% of the way through (I started Friday afternoon).
Working on some fun/silly projects.
My favorite so far is: "The Anti-AI UI Test".
After ChatGPT Atlas came out I thought it would be fun to find UI patterns that AI browsers couldn't figure out like multiple download buttons, hidden unsubscribe buttons, etc. So I created 7 levels of web dark patterns for AI browsers. You can try it yourself if you want:
https://codinhood.com/anti-ai-ui
I found Atlas can get through most patterns, so I created an even more unhinged one (job application form) that shifts the interface and flashes content.
Don't take it too seriously as actually testing AI browsers, it just a fun side project. I documented the patterns here: https://codinhood.com/anti-ai-ui/about
Pretty funny. I had to disable my ad blocker to be able to play it at all.
This is hilarious. Well done!
It was fun. xD
I'm working on a local multiplayer party game platform, a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. We just won silver at the Big Indie Pitch competition!
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs necessary to play
- The games are all action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia games!
- In the future we plan to open up the platform for 3rd party developers as well. We take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking coded and infrastructure.
Would love any feedback you might have!
I wish you luck!!!
I tried this in 2014 with happyfuntimes
https://docs.happyfuntimes.net/
My conclusion was, past a certain number of people no one wants to game
Around the same time was AirConsole and still available
Thank you! Very interesting, maybe 2014 was too early for this kind of gaming, as now the concept really seems to resonate with people and we have been enjoying quite many months of doubling user amounts. But of course time will only tell...
I know AirConsole also struggled quite a lot in the beginning and now in the end they ended up in car entertainment as KPIT bought the whole company. So they don't focus on web/living-room gaming any more
Comment was deleted :(
This is awsome! Exactly what I was looking for. I will try it with my friends tomorrow evening. I have multiple failed attempts of building something similar.
Thanks! Let me know how it goes :) There's also a Discord link at the bottom of our page where you can send in feedback or ask any questions you might have. Would you be interested in developing for a platform like this?
How does this compare to AirConsole? (https://www.airconsole.com)
The underlying technology is largely the same, but our focus is specifically on the action party game niche, whereas AirConsole tries to cover a bit of every gaming genre and position itself as more of a replacement for traditional game consoles.
They were also very recently acquired by an Indian car software manufacturer (KPIT) and no longer focus on web or living-room gaming.
Discovered in-door bouldering / rock climbing and now go 3x a week, am absolutely loving it! Because of that, I haven't really worked on any side projects in a while. Perhaps I don't need to? My job advances me plenty in my field, but it is a bit of a bitter-sweet feeling in a sense, like maybe I should try to squeeze more out of my free time somehow.
I climb a lot! (Actually currently sitting on Big Sur ledge on el cap posting this). It cuts into my free time programming for sure, but imo super worth it! Enjoy it, it’s a wonderful hobby.
I’m replying from the cold east coast (from the edge of a wood chair in a lovely iykyk type of restaurant) to a human posting from el cap on hn; We have achieved peak technology. Oh yeah, I’m working on urban logistics, powered by AI.
I’ve been hesitant for fear of injury harming the ability to type, but might give it a go in the spring. Thanks for mentioning this I’m inspired to try it finally.
I struggled with hand and wrist pain for years from spending too much time at a computer. I did physiotherapy for years and while it helped me manage pain, I was never able to truly build enough strength to get ahead of it until I started bouldering. I took it very slowly—I spent months on very easy problems—but because it was so much fun, I kept going back. Initially, I would only go on Saturday mornings, so I had the full weekend to recover before jumping back into the work week on Monday. After a two or three months of that, I was able to climb anytime I wished. I'm still not a particularly advanced climber, and I typically only go once per week, but I am still slowly progressing, and I absolutely love it.
Couple things to avoid finger injuries: go easy on one- and two-finger pockets, use an open crimp whenever possible (all finger joints are bent the normal direction, and your palm/thumb aren't really involved), and don't bother with the hangboard or campus board for the first ~year.
I wouldn't worry about it too much though - almost all of the people I know with finger injuries were trying to push into really being competitive climbers, not just doing it casually for fun/fitness.
Oh also to keep from tearing your skin don't climb tired. (That won't keep you from typing, it's just painful.)
I'd like to add to this that do not make any food with chilli peppers like habanero or such if you just came from the gym with torn skin. I found out the hard way.
I’ve been climbing for 20 years and it’s the thing that prevents RSI for me and makes it possible to use a computer too much :). Certainly possible to injure fingers but would be a very rare climbing injury that would threaten coding.
Climbing easy routes in a gym is pretty low impact. It’s only when you start to move into really hard crimps or slopers where you’ll hurt yourself. I was a climber bum for years and have climbed crazy stuff around the world and never hurt myself to where I couldn’t type. A lot of bloody tape, but still able to type.
Try top rope climbing! Bouldering is injury prone because every fall is a ground fall. With top rope climbing you should never hit the ground so way less injury prone.
I love the intense concentration for martial arts, but I had to stop because of this.
I never had a serious injury. Instead it would be minor injuries, that would make my ring finger 20% less responsive, that would totally mess up my typing cadence.
I tried capoeira, a non-contact martial art, for a while. This wasn’t as good for me as Taekwondo.
I'm building CommitKit, a tool that turns your git history into résumé bullet points and STAR-based talking points for interviews.
After being downsized twice in two years from senior engineering roles, I realized how painful it is to reconstruct what you actually accomplished at a job once you’ve lost access to your repos.
Each time, I had to dig through memory and scraps of old PRs to remember what I’d built. The first time, I lost GitHub access immediately after the layoff notice. This time, at least we got 90 days of paid transition work. But even with just 5 months in the role, I’d already made hundreds of commits. For engineers who’ve been around for years, that’s an impossible amount of history to summarize manually.
So I’m building CommitKit, a command-line tool that scans your repo for your commits, groups them by feature or theme using embeddings, and generates professional CV bullet points or behavioral interview summaries. It runs locally using Ollama, so your commit messages and diffs never leave your machine. The goal is to help people quickly turn real engineering work into clear narratives of impact, especially when time or access is limited.
It’s still early: the clustering isn’t grouping commits quite as I’d hoped, possibly due to sparse commit messages or embedding quirks. But it’s been a great learning project: my first CLI tool, my first deployment on Render, and my first serious use of Ollama for local LLM inference.
Nice! When I was leaving a company after 4 years there, I went through jira + my git commits to write a log of everything I'd done. Really great look back.
Yeah I really want to add a JIRA integration as well, that would likely improve the output a lot.
Great to hear Render worked for you!
I’m terrible at maintaining my resume/cv so I think this is awesome!
Me too! Such a chore!
A 68030 based computer - https://github.com/jeffsponaugle/roscoe
It has been a super fun experience so far - I'm using CPLDs instead of an FPGA which makes the logic a bit more era period. I have a working system now with the math coprocessor, SRAM, DRAM, and other device support.
I am just about ready to get the VGA card I designed produced so I can work on debugging the design.
While this is fundamentally a system that ss less powerful than my apple watch, it is just fun to work on. Going back to very first principles debugging, building tools, and of course getting to exercise an old logic analyzer!
The software engineer in me wanted a break, but the philosopher and systems thinker wanted to speak.
So I've been building something with no imported libraries or dependencies: a card game that gamifies Maslow's hierarchy of needs: https://gamefound.com/en/projects/nicomar/actualize-this
Each player drafts cards that represent ways you can spend your limited time on earth to gather resources (wisdom, gold, and virtue) to complete your own personal player board (your hierarchy of needs) with the goal of reaching self-actualization before other players. However, you can still win without becoming self-actualized, if you complete more hidden quests (which can only be discarded by the "therapy session" card).
I have to say, i love this. The name is fantastic and the whole concept. It's got a very Game of Life or Monopoly feel where you've just taken the fundamentals of something in society and turned it into a game instead of adding an additional story on top. I really like it.
My one comment would be, I think you need to change the branding a little bit. It's a bit too close to Magic the Gathering, and this feels like its own IP and can stand on its own legs. So I think you need to just adjust the cards enough so they don't instantly read as a Magic the Gathering card.
It looks really cool! I subscribed to the gamefound website specifically to follow this. Hope you have a great time building! :)
Building https://floxtop.com/, a Mac app that organizes your files and images.
It looks inside each file to see what it’s about, then moves it to the right folder with a single click. Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It already works with images, Office (Word, Excel, PowerPoint) PDFs, ePubs, text, Markdown, and many other file types (30+) in English. Next I’m adding multi-language support.
If you have messy folders anywhere on your Mac, Floxtop can help.
Try it for free - requires macOS 14+ with Apple Silicon: https://github.com/taranntell/fallinorg/releases/download/1....
Looks very useful.
Just for clarity, it looks like image content itself isn't addressed, but rather just any text that might be in an image, correct?
Also: "Your sensitive data never leaves your Mac." Does anything leave the mac? Any metrics? I don't want this to have network capabilities at all.
Correct — right now Floxtop classifies images based on text only. It does not yet classify based on visual objects. If automatic object-based sorting (e.g. detecting pets, buildings, etc.) would be useful for you, I’d be interested to hear your use case.
Regarding privacy: everything runs locally on your Mac. No files or metadata are uploaded anywhere. The only network request is from Sparkle to check for updates. If you prefer, you can disable update checks and Floxtop will have zero network activity.
If you have questions or want to share feedback, you can reach me anytime at floxtop@proton.me.
Fantastic, thank you.
This is already useful. If you do wind up adding image classification, first, I'd like it distinguish photos, screenshots, and graphics. Then, I'd like broad categories, like people, places, animals, memes, etc. Base case is I want sort out my downloads since I generally download something and then not bother putting it where it belongs or deleting it.
It would also be handy if, in addition to moving the items, it could tag them via Finder tags/xattrs.
This is cool! I’ve added these to the backlog—I also think tagging with Finder tags/xattrs is a great feature. Thanks a lot for sharing your ideas!
If you want to stay updated when these features are ready, feel free to subscribe to the newsletter.
It's cool to see this. I once saw an X thread on this and hacked a dirty tool for it: https://x.com/priyankc/status/1893112673434222985
You know what would be a godsend would be marrying this app up with the Johnny Decimal filing system
btw I think your profile lists a different url for the same product
Started work on a project to put local history on a map. If I go somewhere I would ideally want to just open this webapp and immediately get presented with cool or interesting history that happened close by.
Maybe it's a story about named local fishermen from the early 1900s, with pictures, the history of a statue and videos of the process, or the state of a graffiti wall over time.
Currently in a phase of UI development and testing, and historical societies outreach for collaboration. It might stall and just fizzle into nothing, or it might be something cool.
Also still doing https://wheretodrink.beer, but haven't added anything of note since playing on this other project.
Ever since I discovered Gypspy nearly a decade ago (now Guidealong https://guidealong.com/) - I've been dreaming of an open source app that'd pull local history from sources like Wikipedia, those roadside historical signs, etc., and narrate as you drive.
https://autio.com/ is similar - but obviously not open source, and more limited.
It seems like it could even tailor itself to what an individual user is interested in, and with AI - could turn more "dry" encyclopedia-type information into more compelling narratives. With some kind of route planning software, you could even pre-plan your trips ahead of time and select the things you're interested in.
Obviously not what you're building, but something related that's been clunking around in the back of my head for a while.
Yeah, that's cool. Currently tangential, but conceptually not something that would be completely out of scope in the end. I'm planning to use machine translations, text-to-speech, and multi modal generative models for accessibility already. There's also an idea for baking in GPS audio tours. Obviously depends on sourcing some quality content first
When you say open source is it so you could self host it, use your "own" models, and curate your own datasets? or some other reasons? I could see a future where a lot of the project could potentially be open sourced and work with any defined geojson API.
Open source was the wrong term (though that would be fine).
I meant community-sourced. Some kind of community where local "experts" or history enthusiasts could contribute info.
AKA - invite a local or regional historical society to contribute data for their region, with the benefit that they could then easily generate a regional tour map/route/recommendation.
Aha.. yeah, that makes a lot of sense. I think that's probably the best way to catch the more niche and special interest history.
Unfortunately only web based: https://www.hmdb.org
Built something similar almost a year ago during the holidays [1]. Open-source if you want to check it out [2]. I use the mobile app version from time to time when I'm going on walking adventures around the city.

Related to wheretodrink.beer, I just launched a rough version of: https://www.nomnominees.com/. A site focused on finding award-winning breweries/restaurants to check out.
Raptor - a new (Free software) way to build things like:
* Disk images
* Liveboot isos
* Container images (docker/podman)
Many build products are supported, with more on the way:
https://chrivers.github.io/raptor/builders/index.html#compat...
It uses a syntax that is inspired by Docker, but significantly enhanced.
Take a look at:
* The project: https://github.com/chrivers/raptor/
* The book: https://chrivers.github.io/raptor/
I recreated a little tool to simultaneously mount all the commits in a git repository as directories at the same time (but re-use the same inodes for the same content).
The code is at https://github.com/matthiasgoergens/git-snap-fs
The original was in Python and actually had a decent excuse for existing for a very specific problem at work a few years ago. The new version is in Rust and exists just for fun.
This was also a small experiment in coding with OpenAI's codex. I wrote the Python original by hand---like a caveman. Codex was mostly ok at the actual code, especially once I told it to make `cargo clippy` happy, but it needed lots of help with the design. It kept insisting on extra complications and state.
But perhaps I'm a bit unfair here, because I only figured out the nice and simple design after reflecting on the connection between Linux's fuse and git's design for a while when writing the original. So it's only fair that the computer would also need some help to see how to match them up nicely.
Could you expand on what problem the tool was originally built to solve?
We had a bunch of quants who were writing Python and Matlab code.
Previously they just saved it in a (Windows) Shared Folder and it automatically showed up in the test cluster. No version control, no nothing.
The test cluster had actually grown to a few thousand machines or so. Running Shared Folders over that was crazy, and no version control was crazy, too.
In addition, they expected to be able to write output files next to the source files, and expected them to show up to be used by the other machines.
We were trying to help them migrate to something saner. We could convince them to not intermix source code and output files, but as part of that bargain otherwise they wanted everything to look as similar as possible to before, but still support some git-goodness we have promised.
To make matters worse, they had checked in some rather large files into their repository. Like Gigabytes, and lots of them.
As before, we wanted to support running multiple processes at the same time, but this time on different versions. As a joke I suggested to 'just mount' the git repository directly (that we constantly pull to every computer in the cluster), but my boss thought it was a grand idea, thus the tool.
An additional nicety: under the hood 'git stash' consists of two phases, the first phase make something like a commit from what you have lying around in your repo, the second phase cleans up what you have lying around. If you use libgit2 (or a similar library) you can use just the first phase to get something like a commit, and send that to the server to execute, while changing nothing on the quant's machine, and not forcing them to explicitly make a commit nor polluting their git history.
One saner alternative would have been to just make a checkout for each run. But naively that would have taken more storage space than we had, thanks to those big files. Alternatively, we could have done some sharing for running the same version. But that would have involved some reference counting etc and cleaning up.
So my suggestion was to 'just let the kernel caches handle it'.
In the end, the prototype was useful to get the quants to get along with what we did. And luckily for our sanity, we could soon convince the quants to store those large files somewhere else, and not in the repository along with the code. That restored our sanity, and we could move to a more conventional scheme.
The working life of the tool was blessedly short, but it played an important role in getting the quants to move along in their journey to using version control. Though even though on paper it might have looked like an abortive and wasted effort, in terms of business value it was very successful.
I love the quants. They are very technical and very smart and effectively write software all day every day, but they don't see themselves as software engineers, and they aren't.
I recreated it just for fun, because I like the connection between git and how filesystems work. You can really tell that Linus Torvalds, the original author and designer of git is an operating systems guy.
Built a local-first Kanban board with Tauri (Rust + Svelte) after getting frustrated with SaaS tools and basic offline options. Stores data in JSON files you control, full keyboard-first UX, parent/child tasks, release management, and it's blazingly fast with localStorage + background sync. No telemetry, purely local. Curious what others prioritize in personal task tools. Seems like there's a gap between "todo.txt" simplicity and Jira complexity.
Cool. Love Tauri. So the whole board dataset is stored in localStorage? If you get to a point where the size limitations or synchronous blocking operations are an issue might consider using IndexedDB. There is a nice higher level wrapper around it called Dexie that has full TS typing support and a nice async API. https://dexie.org/
I’m still using redmine. It allows me to create a project, break it down in to tasks, assign time estimates for the tasks, assign % complete, log time against tasks, which then allows for burn down charts so I can see if I am on track or behind. With time logged against projects I can generate timesheets and invoices. It also has Gantt chart which is handy for initial project planning meetings.
I wanted to build something like that. It would be great if I didn’t have to. Any link to follow?
I’d love even a screenshot! Neat.
Working on a programming language for webapps!
Speed is not an optional feature on the web. The site above is written in Firefly, uses hydration, and scores 100% on PageSpeed Insights.
The language is largely complete, and we're now working on DX: Got a language server, a devserver, and some essential libraries.
This looks good! It feels a little bit similiar to ReScript. I like the idea to have nodeMain, browserMain and buildMain. The Roc language had something similiar with platforms and I love that idea!
In general I prefer a better language over an involved javascript framework that does not look like js anymore.
Thank you! Yeah, I think some of the newer frameworks really complicate dataflow. We're trying to keep dataflow clear, though it's a big design space given the distributed nature of webapps.
In any case, if you take it for a spin, I'd love some feedback.
After taking a break from frontend development from a large corporate client. I wanted to get into iOS development to see how mature SwiftUI has become and finally get a chance to build my first iOS app. The result of that: PeekCard - https://peekcard.app
A simple iOS app for scanning (almost any) barcode and storing in the app, or adding it to your home via a widget. No tracking, no subscriptions, just a simple free app that is pretty simple to use and does the one thing I want it to do.
Building my own software has been super refreshing compared to working within a large organization. I really enjoy the path of just developing and it is fun to get into something different than React/TypeScript and Java. It was also really interesting to go through the process of publishing the app in the Apple App Store. Heard so many bad stories, but it was OK. Definitely not great, but not as bad as I was expecting.
Two learnings from this so far:
1. I do not think that I would want to do any Swift development in a large organization. Super fun to build indie style, but I can't imagine having to support 5+ years of old iOS versions. 2. I ditched most social media a long time ago and if you do not have any personal promotion channel, you are super limited into reaching any potential users for your software. I still do not know how to deal with this; I do not have any ambition to go back into building a social following. I just like building the "thing", but just building it is definitely not enough to get any traction.
For the current project I am building another iOS app, a bit more complex, also something I want to use myself. I was considering building with React Native, but ditched that plan because when I am building for myself, there would (I think) be a lot of overhead in testing Android.
For now I really like what I am doing, but financially I think I should consider going back to Java/Scala or React dev for a corporate client :-|.

My friend had a cute baby boy and mentioned difficulty in finding children's storybooks in Spanish.
Challenge accepted:
I built an AI generated multilingual storybook, just to see if it would work.
Tap or click the little monster to have it read to you.
Local LLM generated the story, stable-diffusion generated the images, AI converted text to speech in two languages: English and Spanish ( could easily do many more languages ).
I "filled the app out" by adding a simple landing page placeholder, login page and "library" page.
Not very phone friendly, was made for her iPad.
Only the second book currently has a story, the others are placeholder templates.
Cool. This concept is useful for adult language learners also. Depending on the language you are learning it can be very difficult to find reading material in the age 5 - 10 range to practice with.
Still very focused on making light healthier. 3 new products:
Bedtime Bulb v2[0]: A massive improvement over our original Bedtime Bulb, a light bulb meant for use in the evening to reduce blue light. The headline feature is the re-introduction of infrared, which was removed from lighting to make it more efficient, but emerging research suggest it's beneficial for health. After a long wait, this is shipping in 2 weeks!
Atmos Bedside Lamp[1]: A fully automated circadian lamp that automatically shifts in color and brightness throughout the day, helping you prepare for sleep and wake up more naturally. Working on some machine learning features that mimic the functionality of the Nest Learning Thermostat, but for lighting. The first units are shipping by Christmas.
Circadian Mode for Philips Hue[2]: A web app that gives your Philips Hue lights circadian powers, so that they gradually shift from bright light during the day to dim, low-blue light at night. It's way more powerful and easier to use than first- and third-party options from Hue, Apple, and Home Assistant. Just launched this week; looking for beta testers to give feedback!

Over the years, I've read countless books. I started documenting one idea that shaped my thinking from each of these books. This idea may or may not be the core theme of the book.
Hope to document 100 ideas. Wish me luck.
looks cool!
I was hitting Claude Code's rate limit pretty often while paying for their max subscription. Started thinking – I've got a decent GPU sitting at home doing nothing most of the day.
So I'm building a distributed AI inference platform where you can run models on your own hardware and access it from anywhere privately. Keep your data on infrastructure you control, but also leverage a credit system to tap into more powerful compute when you need it. Your idle GPU time can earn credits for accessing bigger models. The goal is making it dead simple to use your home hardware from wherever you're working.
It's for anyone who wants infrastructure optionality: developers who don't want vendor lock-in, businesses with compliance requirements, or just people who don't want their data sent to third parties.
Get notified when we launch: https://sporeintel.com
I don't want to get into blockchain-shenanigans but I did love the Folding@home model for democratized compute. Could spare cycles on GPUs at home be used for a P2P network of inferencing?
Yeah! not building a blockchain but we are building a system similar to folding at home (also a fan of that) where if you choose to have your node process others peoples requests you will get credits that you can then use to spend on other people nodes on the network. This is so you can still be able to use models that may be too big for your own hardware when you need them. Overall goal being to prevent people getting priced out of AI and providing and alternative way of accessing these larger models.
Couldn't you do that with Ollama + Tailscale? Minus some of the fancy bells and whistles?
Yea that would be the best current solution out there and would work ok for one person with one computer but the average person isn't going to set that up and it isn't easy to use from any device just by logging into a website or app. And if you had multiple machines you'd have to manually load balance by switching between them. Spore will allow you to easily set up as many nodes running models as you want and manage what models they are serving from anywhere, this allows for simple servicing of an organization or your family for example.
lol. I keep on hitting my usage limits but I haven't upgraded my Claude Code CLI... so I just continue

Running OpenStreetMap off the grid (self-hosted to say the least) on a Raspberry Pi 500 (and to some extent a Pi Zero 2W) for Internet In a Box:
https://www.linkedin.com/posts/danielkrol_openstreetmap-acti...
All of the street and satellite tiles are thanks to maps.black. The search uses Nominatim's sqlite3 mode. I was told that it's experimental only because it hasn't been tried in production yet, so I'm sort of testing it in the process. So far I'm only doing administrative boundaries and natural features, but so far so good! I'm going to slowly add a few more types of POIs, I just don't want the database file to get too big.
Note that Internet in a Box has an OSM offering already, but the data is five years old and the tech makes it harder to update. As of today, there are much easier options on the table, and we get cool stuff like 3d buildings. Also, the search was much more limited.

Trying to fix this problem with Eternal Vault.
Link: https://eternalvault.app
Another thing thats in early alpha right now is CapKit, AI professional captions for short form videos
Eternal Vault is interesting. I would for sure use something like this. However, only if there is a strong story how the vault will survive 20+ years, even if your company is defunct. I do see the pieces scattered around the website (backup to Dropbox, etc), but this story needs to be front and center.
Hi Luke, thanks for the feedback. Will be working on improving the marketing site to share the story in better way, any other feedbacks are also appreciated. Lastly, would love for you to give the platform a try at https://dash.eternalvault.app/register
A few months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?” Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?”
Turns out not that hard.
In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless.com/
Just to play a bit of shark tank, why would I use your tool instead of Docuseal, which is FOSS and self host able?
Building the world’s first “Travel Confidence Engine.”
I’ve been obsessed with how people actually make travel decisions — not how platforms think they do. From a consumer’s standpoint, travel isn’t just “search → compare → book.” It’s emotional, contextual, and full of FOMO.
You open 20 tabs across Booking, Google Maps, Reddit, and Instagram trying to answer simple questions like: Is this the right area? Is this hotel actually good? Am I missing a better deal somewhere else?
Most existing tools either oversimplify (like ChatGPT giving three confident but unverifiable answers) or hide information behind algorithms and commissions (like OTAs). Both remove choice — and ironically, make people less confident.
I’m building SearchSpot, a “Cursor for travel.” It automatically does what power travelers already do manually — cross-check reviews, verify real photos, compare prices across platforms — and then shows its reasoning transparently so you understand why something was recommended or excluded.
The goal isn’t to replace your decisions, but to help you close your tabs with confidence. From FOMO to flow. From chaos to clarity.
If you’ve ever spent hours researching a trip just to end up more confused, I’d love your thoughts: https://searchspot.ai/home
Why does it need a login though? big friction to just see the result of search
yeah, but there's no way to reach out for feedback or follow ups if not logged in. At this stage, we want loads of feedbacks and help genuine users plan their trips well, hence the login wall.
Well, as a "genuine" user, you'll never get so far as to get feedback since I'm (and likely others too) not going to bother with a tool that I can't even test its authenticity, correctness or usefulness of over known good individual routes for information. So if you want feedback; lower the friction. If it's useful, people will make accounts. E.g. too save searches and whatnot.
I built this: https://github.com/dvcoolarun/web2pdf — a CLI tool for converting web pages to PDFs, recently open-sourced after adding several new features. (Might be useful!)
Not related to the thread, but if anyone is looking to hire a developer or knows of opportunities, I was recently let go and am actively searching. Any leads or feedback would be greatly appreciated.

I'm working on Flavia, an ultra-low latency voice AI data analyst that can join your meetings. You can throw in data(csv's, postgres db's, bigquery, posthog analytics for now) and you just talk and ask questions. Using cerebras(2000 tokens per second) and very low latency sandboxes on the fly, you can get back charts/tables/analysis in under 1 second. (excluding time of the actual SQL query if you are doing bigquery).
She can also join your google meet or teams meetings, share her screen and then everyone in the meeting can ask questions and see live results. Currently being used by product managers and executives for mainly analytics and data science use cases.
We plan to open-source it soon if there is demand. Very fast voice+actions is the future imo
This sounds amazing. A demo video would help me finish sign up - I can’t try it without hooking it up to real data, and I don’t want to for a test.
Great feedback thanks! We have added a synthetic e-commerce dataset as an example when you sign up so you can test it without your data first. Will also add a demo video ASAP.
What kind of plan do you have with Cerebras? It seems like something like that would need one of the $1500/month plans at least if there were more than a handful of customers.
They introduced pay as you go recently. The limits on that is similar to the plans, 1 million tokens per minute, so if you stack a few keys and do a simple load balancing with redis, can cover a decent amount of traffic with no upfront cost. Eventually we would have to go enterprise though yes!
ok.. when I tried to use pay-as-you-go it was unusable for me because there were a ton of 429s and 503s. one test it was just constant for a few seconds when I tried it, 429 or 503.
I am using it for a voice application though so retrying causes a delay for the user that they don't expect. especially if it stays unavailable for a few seconds.
Hey! I have a business inquiry for you but I don't see a contact anywhere on your website. Is there a place I can reach you? Thank you!
are you guys built on recall or did you guys build out the meeting joining functionality yourself?
I'm building a small rural ISP and web hosting service, as a way to learn about low-level networking stuff. I've got an ASN + IP space, and am working out the details with a colo, local fiber provider, and some upstreams. Right now I'm configuring the hardware itself (server, router, switch, etc) and learning all the bits and bobs (Proxmox, BGP, OPNsense, IXPs, etc)
All I can say is good luck. We spun up a co-op isp to take advantage of fiber grants for rural areas about a decade ago.
Maybe it was because of the grants, but it was a fucking nightmare getting off the ground even though we had nearly 90% of the population in three counties on board for the co-op. The red tape and regulations (in our state at least) made it clear that government runs for urban and suburban interests and actively undermines rural needs. I'm talking government in bed with large providers who had exclusive rights to run "high-speed" Internet to our towns and farms, even though they had never and were never planning on anything above dsl for most people and cable for the ones in town.
If I was more charismatic (and wasn't 1000% sure there were pictures of me doing drugs when I was in college), I would consider a run for state office, because it's a shit show for small towns here.
And that's the story of a) when we got sued by a large provider that I hope goes out of business and burns to the ground, and b) the last time I volunteered on a large project and why I will never take the lead on anything bigger than the Lion's Club pancake breakfast now.
Oof, thanks for sharing and the well wishes.
I'm funding this myself, and my current approach (hopefully!) avoids most of the red tape. I'm leasing fiber from a local ISP for the colo <-> my home connection, and once I have myself as a successful "customer" of my own ISP, I'll start doing the last mile build out, which is where I expect the red tape to begin.
But I haven't decided if I'll do fiber or wireless, and if I go wireless, I might be able to avoid pole agreements entirely by just working directly with my neighbors. The problem is that our area is pretty heavily wooded, so I'm not sure if I can place antennas high enough to cover a reasonable swatch of the area.
Our best approach was to run fiber in the ground in the public right-of-way on county or local streets and avoided the state highways. It was much easier to get easements with property owners and local towns than the state (as far as I know, our request is still sitting unread with the state). That meant we had to build twice, essentially. Once for the north of the major highway that bisects the area, and once for the south. But that cut out all of the nonsense with existing agreements from the state. So that helped.
Most property owners we had to cut across were willing to forego payment of any kind for free fiber hardware, and access at reduced rates for 10 years. So that was nice.
We didn't evaluate wireless, just because of the terrain, but I do know a local chap who is providing that for folks using grain bins for line-of-site access points. That's seemed to work well for his use case.
> If I was more charismatic (and wasn't 1000% sure there were pictures of me doing drugs when I was in college), I would consider a run for state office, because it's a shit show for small towns here.
Loads of politicians have come back from worse! Don't let that hold you back.
Best of luck with this. If you get the web hosting part going and need to stick a load balancer in front of web servers/front end proxies, may I suggest that you give my project[1] a go? Speaks BGP directly to your routers to advertise healthy services and scales from small VMs (for services that are only a few gigabits/s) to physical servers if you need to serve tens of gigabits/s traffic.
Shameless plug, sorry (not sorry!) but I would have killed for it when I worked in web hosting :-)
I'm reviving a project I last touched in 2006, in the hopes that it might be of use today in making social networking human again.
Back in the day, after the company I worked for bought the Electric Minds community and migrated it to its own CommunityWare system, and then the company that bought our company decided to shut the platform down, I reimplemented the community platform in Java and helped rescue the community. See: https://erbosoft.com/blog/2025/09/08/electric-minds/
EMinds eventually sputtered out because of the rise of platforms like Facebook. Well, now we see what came of that. So I think there's room for a platform like the one I used to have. See: https://erbosoft.com/blog/2025/11/03/what-we-once-had-and-co...
The new system is being written in Go. I'm porting the code over without using AI, though I have used Claude to translate the old crusty HTML pages into modern HTML with Tailwind CSS. Once it gets to the functionality I had back in 2006, I'll put it up...and then see about going beyond that, including how to make it distributed and provide more interoperability.
Every time I talk acquaintances, friends and family members about finances I'm always shocked at how little people know about basic things like tax brackets, 401Ks, IRAs, ETFs, compounding interest, debt management and etc. So I decided to write a financial literacy/education book with a bit of humor and easily comprehensible language to distill some of these topics. I'm about 1 month into it and try to write a chapter a week.
Really good idea, perhaps you can include some simple guidelines for long term investment as well.
Looking forward for the publication of the book and buying it.
Do you have a sample to share?
Just some drafts in markdown but nothing I can share just yet. I'll be posting it here once I have the ebook done.
I've been working on a sillier project lately. Green teeth!
Lumina has made a probiotic strain that is able to, theoretically, prevent cavities. I don't care that much about, but I do think it is a neat strain that can likely colonize your mouth. I'm genetically engineering it to express sfGFP, which would theoretically make my teeth fluorescent green under black light. Would be fun at raves! Also, if I make out with anyone, you could theoretically see changes in microbiome composition just from green-ness. I do wonder how much microbiomes are shared while kissing: this would be an example of a way to directly measure that, instead of just measuring on proxy like much microbiome research
In future: Papa, why are humans' teeth green?
- Oh, son, let me tell you a story about how an ancient dude called koeng wanted to see how many people he kissed.
That sounds so cool. Could you tell me more?
Working on Strot - an AI agent that reverse-engineers website APIs for scraping.
Instead of DOM scraping, it intercepts AJAX calls and figures out which API endpoint gives you the data you need. Uses visual analysis + fuzzy matching to identify the right call.
The use case: scraping product reviews, paginated listing data (products), etc. Existing AI scrapers either didn't work or were very slow and costly. A product with 1000 reviews takes 10+ minutes with Playwright, costs $10 with LLM scrapers. With Strot? 10 seconds via direct API calls.
Being used in production by a couple of clients. Would love feedback!
Blog: https://blog.vertexcover.io/strot-is-a-api-scraper GitHub: https://github.com/vertexcover-io/strot
Very neat - I imagine you could even use this as a web scanner to identify security misconfigurations in API implementations (e.g. broken access control)
Since I got a baby and we’re still adjusting to their schedule, I’m still working on the same project, Librario[1]. Librario is a simple book metadata aggregation API written in Go. It fetches information about books from multiple sources, merges everything intelligently, and then saves it all to a PostgreSQL database for future lookups.
You can think of it as a data source, or a knowledgeable companion that can provide comprehensive book information for online booksellers, libraries, book-related startups, bookworms, and more.
I got a pre-alpha build running for those that want to test it out[2], but the code is still not out there, as there are a few things I want to refactor. Wrote comprehensive documentation for it this weekend, now I need to refactor the merger package with some new rules, and write something to decrease the number of genres returned.
Been tough to find time to work on it because of the baby, but AI has been helping a lot to speed things up, and the work has been quite fun. Not sure if there will be interest in the idea, but it solves a problem I have, so I had to work on it anyway.
Hope to have the code on GitHub by the end of this week. AGPL licensed.

I’m working on https://regularly.co/ - A website made for inquisitive minds to get their daily puzzle fix. Still very much a WIP (mainly working on tuning the difficulty of puzzles to make it enjoyable for most). That being said I really do enjoy the unique combination of puzzles when I do them each day. I’m looking for feedback so if you do take a look please do let me know your thoughts!
Incredible. Thank you for sharing this, I love puzzles and like setting aside some time in the morning to do them. This will enhance that habit so much! A whole slew of daily puzzles, I'll let you know how it goes!
I don't understand why I can't place two kings in "adjacent diagonal" position when they're in two different regions. Something like:
..k..
.k...
Rules state they must be in different regions, row and column. No mention of diagonal or adjacency.
Maybe it wasn't there when you played, but rule 6 states kings cannot attack each other; chess kings can move one square in any direction. Without this rule the puzzle isn't solvable by logic, only trial and error.
Ah this rule is mentioned under “Kings cannot attack each other” (in the chess sense, two Kings cannot be diagonal from one another). I’ve updated the rule to make this a little clearer
I agree, I had the same problem.
I'm making an HID translation dongle.
In programming mode, its a flash drive you can put LUA scripts on.
In run mode, you can select a lua script to run. Lua scripts can take HID input and produce HID output.

It can do things like keyboard -> joystick mapping, key logging, macros, mouse wiggling etc etc
Hey cool! I've been wanting something like this for a while.
Would it be able to take multiple inputs?
There's plans for a future iteration to be able to (I want to decouple multiple keyboard inputs!).
However in the git repo and prototype, ATM it's 1 input 1 output.
An algorithm to optimise vacation days using public holidays and weekends. Especially relevant at this time of year.
I created it a year ago and received quite some comments on the Show HN post[1]. Last weekend I updated it to work for end of year planning and adding fixed days off, which seems to solve most of the feedback. It was done with Cursor in agent mode.
Hey HN! I'm building https://openfret.com/ - the all-in-one platform for guitarists that I wish existed when I started playing.
OpenFret combines everything a guitarist needs in one place: smart gear inventory management, AI-powered practice sessions, real-time collaboration tools, and a vibrant community. Think of it as "GitHub for guitarists" meets comprehensive practice tool.
Core features:
1) Smart Guitar Inventory: Track your collection with auto-filled specs from thousands of guitar models. Monitor woods, pickups, scale length, string changes, and discover patterns in your gear
2) AI Practice Sessions: Generate personalized guitar tabs and lessons based on your practice history, with VexFlow sheet music and integrated metronome
3) Session Mode: Fork and merge music tracks like code. Layer recordings, see version history, and collaborate with musicians worldwide
4) Practice Analytics: Persistent timers, song tracking (Last.fm integration), scale visualization, fretboard maps, and chord progressions
5) Built-in Tools: Guitar tuner with frequency control, Strudel integration for backing tracks, and musical helpers to break out of E minor habits
Looking for:
Feedback from guitarists/musicians on which features resonate most
Link: https://openfret.com/ | Discord: https://discord.gg/G3Pur3PzZm
Thank you!
I think AI guided practice sessions could lead to something incredible but like everything "AI" it actually takes a lot of hard work to make it really useful.
ABISan. Think of it like UBSan, but for assembly.
It's a custom assembler built on top of the LLVM assembler (llvm-mc) that emits instrumentation code to catch ABI violations at runtime. Stuff like clobbering nonvolatile registers, misaligning the stack pointer, misusing the redzone, assuming volatile registers don't change across a function call, etc.
Hoping to finish up basic x86_64 support within the next few days. I can now reliably assemble and run unoptimized gcc output without hitting false positives, but I still have to iron out some false positives triggered by OpenSSL's handwritten assembly routines.
TODO items for the near future include porting the runtime support library into a kernel module so I can instrument Linux, and beginning ports other architectures (ideally something semi-obscure like POWER or RISC-V). I also need to figure out how to support dynamic linking, because the tool currently needs static linking to access its thread-local variables.

Currently working on two OSS projects:
Laketower: https://github.com/datalpia/laketower A lightweight data lakehouse exploration and management app (web+cli), using DuckDB as the default query engine. It can run locally or self hosted, and for now statically configured only. Hope to integrate Iceberg and Ducklake support by end of year.
Modelship: https://github.com/datalpia/modelship An ML model to app generator. For now, only ONNX models are supported as input, and only static website as target (onnx runtime web wasm/webgpu). I intend to also work more on it the following weeks/months, especially to support more model I/O types, and add support for more targets (REST API, CLI, etc).
These 2 projects were born from professional activity needs but are a nice playground to learn and try new things
DIY grid-tied residential solar+inverter+battery. Trying to design the solar arrays' tilt mechanism now for lifting/lowering 5 panels at a time in winter (60-degree winter angle, 35-degree spring/summer/fall; ~24" difference). Thinking either two linear actuators, or a single hydraulic jack connected to multiple support beams. The weight isn't much, but I want a way to lift entire top edge at once to prevent twisting. Linear actuators are slightly more money and easier to build, but require power and weather-proofing. Jack is cheaper, but more complex to distribute force. Wondering if there's other options. (winch would require more robust/taller rear posts, seems more complex, might shade rear array)
Tilting them vertical or nearly so is very useful if there could be any hail, that might be a good idea to support.
What about compressed air? It might not be too hard to find a small brushless low power air pump that could drive pistons directly.
You could mount the pump controller onto the back of the panels and use an accelerometer to measure angle, and run the pump until it's where you want it.
You'd probably need to do some testing and make sure it couldn't get jammed, then build up pressure, then suddenly unstick and move unsafely.
Nice, I started with 5 panels (450W each) and a simple design of interchangeable long and short rear legs to adjust the angle of each panel. Base of leg sits in a bracket on a steel frame, and pivots on an M8 bolt. Top of the leg attaches to some angled 'meccano' steel I affixed to the rear of the panels. It worked great, but I slightly over optimized by sharing legs, which made the twice a year switchover a bit tricky, since I could only manage to lift a single panel at a time.
Last year the 550W panels here dropped to 90eur, and so I just added some more panels to remove the need for the switchover. I saw last week 600W panels going for 80eur but no space left, but tempting. Good luck! It's a nice feeling to have energy independence.
"Projects With Everyday Dave" has done quite a few tests, and may be worth a look:
https://www.youtube.com/watch?v=I-Fz5T5c0OQ
Best of luck =3
Thanks! And I've seen Dave's tests. Since I don't need a fixed angle, do need to maximize production (due to a limited sun horizon), and only have 10 panels, the best option is adjusting angle during winter. The N-S orientation is a really poor performer. (Notice that his test is 30-degree tilt vs N-S; 60-degree tilt will provide 20-25% more power than 30-degree at my latitude, without even considering bifacials w/snow. The only thing that would produce more is an active tracker, but I've got other things to do, and a December deadline...)
I’m working on “Stripe Integration as a Library.” It seems that whenever someone uses Stripe, for example for subscriptions, they go through the same few steps: creating a database table, setting up webhooks, and implementing the events they care about. The challenge of course is that everyone uses a different stack.
I’m building this using our framework for stack-agnostic JS/TS libraries. On the database side, we currently support Drizzle and Kysely, with Prisma support coming soon.
https://fragno.dev/docs/our-fragments/stripe/quickstart
Inspired by the Stripe integration built for better-auth.
Ironically stripe began as "payment integration as a library"
Working on a charity + website (not live yet) that allows you to centrally manage your charity donations.
I'm in Germany so I'm working on a Germany-specific solution for now.
- you choose from a list of charities (right now I'm working with the list from the https://dzi.de plus a few such as Wikimedia Deutschland)
- you setup a recurring donation to our bank account
- we redistribute the money according to your split
- no spam in your email and snail mail
- one pdf at the end of the year for your tax returns
I'm not planning on taking any cut of the donations obviously, so this will be a fully self-funded project at first, but I'll reach-out to foundations once I'm up and running.
The URL will be https://super.giving/ (not setup yet, should be fairly soon).
I'm also planning on releasing the source code as open-source.
I'd be happy to hear your feedback, either here or via email :)
Are you experiencing the HN hug of death or is your website down? Either way I'm super interested in what you're building and I'd love to use it but I cannot reach your link at the moment. Good luck with the endeavor either way and thank you for building this.
Happy you're interested! I haven't set-up the website yet but feel free to reach-out via email (you'll find it in my hn profile)
I am working on Rad [0], a programming language built specifically for CLI scripts, so you don't need to write Bash, and it offers CLI-tailored features which make it a better choice than Python.
Lately I've mainly been working on stability and bug fixes. I've released some big features the past few months so I'm doing a big push on polish, before I again tackle some larger features that I'd like to implement.
If CLI scripts is something you're interested in at all, give it a go! We have docs and a guide [1] for getting started, feedback very welcome :)
[0] https://github.com/amterp/rad [1] https://amterp.github.io/rad/guide/getting-started/
Oh, until the URL part, I assumed you were the creator of Red [1]. I vaguely remembered reading about it a couple years ago, and thought "I don't remember it being positioned as for CLI scripts shrug".
Even seeing 'rad' in the URLs, at first I thought you'd misspelt them there :)
I'm working on fighting IBM's patent trolls. IBM slapped the words 'AI Interpretability' on Gauss' 200 year old continued fractions and was awarded a patent.
Now they can charge rent if they encounter a continued fraction library in the wild.
It's bizarre
Have they actually tried to sue anyone for infringement? Kind of a moot point unless they do.
They haven't and that's the crux of it all: they can sue if they want or when they want.
> they can sue if they want or when they want
If you're assuming that nobody will look at the patent and invalidate it, why would you assume that they can't just sue you for literally any patent they own for no reason? If the court won't care about the fact that the patent is nonsense?
Interesting.
Do you have a link to the patent?
Here it is: https://patents.justia.com/patent/20230401438
On Google Patents: https://patents.google.com/patent/US20230401438A1/en
The authors simply implement a continued fraction library in Pytorch and call the backward() function on the resulting computation graph.
That is, they chain linear neural network layers and use the reciprocal (not RELU ) as the primary non-linearity.
The authors reinvent the wheel countless times:
1. They rename continued fractions and call them ‘ladders’. 2. They label basic division ‘The 1/z nonlinearity’. 3. Ultimately, they take the well-defined concept of Generalized Continued Fractions and call them CoFrNets and got a patent.
IBM's lawyers can strip out all the buzzword garbage if they feel litigious and sue anyone whose written a continued fraction library. Because, that's what the patent (without all the buzzwords) protects.
Thanks for that. That is patently absurd.
You sent me down a rabbit hole. In trying to track it down for myself I read a couple of others that I thought might be it, and was stunned by how obtuse these patents are.
What sort of leverage does this stuff provide? You mentioned "charge rent". What does that look like?
Honestly, I don't even know where to begin. It's insane IBM owns the patent to continued fractions.
If you wrote a continued fraction class in Pytorch and called backwards (or even differentiated the power series) then you're infringing on their copyright.
As a means to learn about both WebAssembly and Rust, I started writing a WebAssembly binary decoder (i.e. a parser for `.wasm` files) from scratch.
Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.)
My aim is probably not for it to become a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes and/or debugging issues with existing modules. That's why I decided not to offer a streaming API, and why I'll be focusing on things like good errors, good code docs etc.
P.S. I'm new to the language so any feedback is more than welcome.
I created a free collection of 4,300+ real website designs (screenshots, fonts, colors, live links)
https://fontofweb.com/u/fontofweb
I was tired of inspiration sites like Dribbble full of polished mockups that aren't practical. Or awwward like sites that don't represent the mundanity of most websites.
So, I spent a while building a tool that captures website design snippets. It's now a collection of 4,363 designs from 544 different domains.
For every design, it extracts:
The exact fonts used on the page (so far 561 unique font families I've found)
The precise color palette
A direct link to the live site
You can check out the full free collection here: https://fontofweb.com/u/fontofweb
Very cool, I will for sure be checking it out from time to time.
Bookmarked. Thanks for sharing!
About 2 years back I began working on a very simple markdown compiler, it was “immediate” in that it would consume markdown and immediately spit html. That project turned into a whole static site generator called Kevlar — https://github.com/aadv1k/kevlar
Entirely built from scratch in C without any dependencies. Now I wrote this code when I was 16, so many memory leaks and generally issues that I wanted to rectify and begin using third project for my own blog (currently old version is used — https://aadvikpandey.com)
The Kevlar v3 (https://github.com/aadv1k/kevlar/tree/kevlar-v3) here is all that it includes; more spec compliant markdown AST-based parsing; A better .ini config parser (right now it’s literally strtok on ‘=‘ and generally very hacky) as well as name spacing; more powerful templating tags like IF, FOR with lisp-like configuration
Of course staying true to the spirit of “from scratch” :)
Honestly I did scope creeped a little since I mainly wanted to fix a memory leaks issue in the markdown compiler lol; anyway I will share it once it gets completed on hacker news :)
> Entirely built from scratch in C without any dependencies. Now I wrote this code when I was 16
Very few young folk are learning C; I think it is commendable that you are.
You code doesn't seem very strongly structured (to be expected, TBH) but much better than any learner would see.
What resources did you use to start learning C? I ask because it looks to me that those resources covered "how to program in C" but not so much design and structure.
Here's two links (my own blog) to get you started on one or two common C patterns designed to minimise bugs:
Hey, thanks for your comment :) I had a look at your blog, it's looks really useful and high quality! I will go through it with vim open on the side and a nice coffee
Yeah and I'd agree with your point. One BIG critique I have for my own 2-year-past code was that I did not know how to do dynamic heap allocation very well, hence you may have seen everything is stack allocated lol
Particularly egrigeous example:
typedef struct ListingItem {
char lTitle[CONFIG_MAX_PATH_SIZE];
char lDate[CONFIG_MAX_PATH_SIZE];
char lContent[CONFIG_MAX_FILE_SIZE];
char lPath[CONFIG_MAX_PATH_SIZE];
int lOrder;
} ListingItem;
So with the V3 release, I am re-writing the markdown compiler for instance, and being a bit more mindful of the structure
Example: https://github.com/Aadv1k/kevlar/blob/markdown-compiler-rewr...
I think once I am done I will create a separate "Show HN" post to get valuable feedback (like this one!) from smarter folks than me. Once again, thanks for the fantastic blog :) will be sure to go through it
Cheers!
Plug-That-In [https://plugthat.in] (Mac App; Paid)
An annoying little laptop charging reminder utility that does the job.
---
There are times when I am deeply involved in a focus-work session, a meeting, OR watching some sort of engaging video content, and don't pay timely attention to the standard low battery notifications from my MacBook.
After the laptop shuts down suddenly, what follows is the most annoying walk to find the charger or the charging outlet. It's frustrating at times, sometimes embarrassing because you have to say, "Sorry, my battery died down" as you join back the session after 2-3 minutes.
Over the last 3-4 weekends, I have been building Plug-That-In, which has floating notifications. Essentially, a notification that follows my cursor movement, so I get a stronger nudge irrespective of what I am doing.
There are a few other critical features, such as Reminder Mode and Do-Not-Disturb Settings.
- Reminder Mode: On critical/lower battery levels, it will keep beeping like a car's seat belt alert for some time (configurable) when the battery is really low.
- Do-Not-Disturb settings: Configure what sort of alert/sound it will generate when I have system audio playing or video playing, or the camera is active.
It has addressed a personal need and has already proven useful a few times over the last weeks.
I recently have gotten into the "drag and drop" forms of programming like Node-RED and n8n.
Obviously, anyone here who has read my posts knows I know how to write code, but having a bunch of built in connectors that are agnostic to each other with the Oauth and the like being somewhat plug and play allows me to iterate on some ideas a lot quicker.
I installed an n8n instance on my server, and have become kind of addicted to making different Discord bots, and I'm having more fun with this than I thought I would. 95% of the stuff on there is basically drag and drop, and when I need more elaborate logic then I can easily drop into JavaScript. I am looking into writing new nodes for different services, and I keep having new ideas for different stuff I want to build.
Check out my project at https://www.MobiusClock.com: A 3D WebGL Clock on a Möbius Strip that shows 24hr time on a 12hr face. The hour indicator follows the edge of the strip, thus must make 2 turns to return to its starting point, giving you a 24 hour clock. The minute and second indicators move along the middle of the strip and thus return to their starting points in only one turn. Has the ability to rotate!
Just added a new feature: a 'Fast Mode' button to temporarily speed up the hands, which helps visualize how the slow-moving parts work, how the hour indicator moves along the edge. Would love feedback on the implementation.
If you happen to have an old or spare iPad or tablet, you can open my mobius clock page in a browser and set it on a shelf (plugged in of course). Kind of like a weird wall clock...
I am working on SecurityBot https://securitybot.dev a service that combines uptime, performance, SEO, and security monitoring. Among other things it inckudes PageSpeed Insights analysis, a broken link auditor (401, 404, 500, etc), and historical ping/uptime results.
I recently shipped an MCP server thst can delivered broken link results to Cursor so they can rapidly be resolved.
I love this - great work.
I’ve been working on ScratchTJ, a DIY digital turntable built with a Raspberry Pi and Arduino Nano. It’s based on the open-source SC1000 code, but with some hardware changes and tweaks to make it easier to build and customize.
It runs on a Raspberry Pi 2 with an AudioInjector sound card, a small LCD screen, a rotary encoder, and even an old hard-drive platter as the “deck.” The goal is to make a simple, open, and affordable way to experiment with scratching and mixing — no fancy gear required.
It’s still in progress, but it works pretty well and has been a fun way to explore DIY DJ tech and embedded audio.
I’m working on Shapiful, a cloud-based platform that makes designing and generating 3D-printable labels and custom objects fast, simple, and accessible to everyone. https://www.shapiful.com The idea is to remove the steep learning curve of traditional CAD tools while still giving you precise, print-ready models in minutes. With Shapiful, you can create personalized labels, signage, tags, stamps, LEGO-compatible pieces, or even board game tiles by customizing shapes, text, braille, or QR codes. You can also upload existing STL files and overlay text or graphics seamlessly, with live 3D previews, parametric scaling, and automatic surface detection to make placement easy. We support a variety of shapes, mounting styles, and text styles (embossed, debossed, engraved, or negative), all designed to produce durable, professional-quality models ready for printing. The platform is aimed at engineers, designers, educators, hobbyists, gardeners, and 3D printing enthusiasts who want fast, flexible, and fun customization without the complexity of traditional CAD software. Essentially, Shapiful turns 3D printing personalization from a technical chore into an intuitive creative process, whether you’re making home labels, company signage, accessible braille tags, or playful DIY projects.
Building https://typequicker.com
I’ve always wanted a typing application that’s both more than typing random words and is data-focused so I built this.
The more you type, the more the analytics system learns about your typing patterns and generates natural text to target those weakpoints (SmartPractice mode).
There’s a lot of variety as well; you can practice typing code in any programming language, or type text of various topics, use custom text, etc).
Porting my 2014 WebGL game (https://phoboslab.org/xibalba/) to the N64: https://x.com/phoboslab/status/1982883072292069641
How are you doing this? Do you have a blog going over the work or a Github page? Just curious, it's an interesting project.
The WebGL game was build with my 2D game engine "Impact", which I previously ported to C[1]. The game has a 3d view, but logic still mostly works in 2 dimensions on a flat ground. The N64 version "just" needed a different rendering and sound backend.
So you're writing the game in C and targeting the N64? Utilizing your custom Impact game engine, which is also written in C?
Do you flash the game to a custom cartridge for testing?
[dead]
I am spending my free time doing a few projects to relax and "fix" a few things that should improve my productivity:
- An AI RSS feed summarizer (https://feeds.carmo.io)
- A PyObjC replacement for the bloated StreamDeck app (https://mastodon.social/@rcarmo/115498602604176483)
- A new keyboard, mostly to get back into SMD soldering (https://mastodon.social/@taoofmac/115521815709828495)
- A bunch of small MCP servers for other projects (https://mastodon.social/@taoofmac/115315732816298110)
- A case for a little server (https://taoofmac.com/space/reviews/2025/11/09/1930) that will eventually run at family's out in the countryside and manage a few ESP32 boards scattered around
I've built a self-hosted reddit-like community platform in Go: https://baklab.app
Users can create their own sub-communities, and within them, set up different categories and boards. Posts can be voted on, and board types can include regular posts, Q&A, or live chat. It's like a hybrid of Reddit and Discord but leans more towards a traditional web community. It also supports server-side rendering, making it SEO-friendly. This project is an extension of my previous Hacker News clone, dizkaz (https://news.ycombinator.com/item?id=43885998).
In network code: most people just let the OS choose a default adapter. It works fine, but it makes it hard to write software that works across machines with either (1) multiple NICs (and/or networks they point to.) or (2) multiple external Internet IPs. Look at STUN, for example.
A STUN server that lets people test what type of NAT they have uses two IPs. For such a server you have to manually specify the addresses to bind on to make for sure its setup right. As it goes, writing network software to do simple things like "bind on all local addresses", "bind publicly", "bind on all", is harder than it sounds. There are edge cases on different OSes and address families, so manually managing IPs is hard to do.
My network software lets devs easily manage NICs and routes they support without guessing about addressing. Additionally, I've written a bunch of software with the library already to do things like NAT traversal. So its really my own redesign of how to do networking on the Internet. Designed to hide a lot of the messiness. I'm still improving code quality so it's not ready yet. But I've been dog fooding with a lot of software written in it and smashing bugs every day.
Project page: https://github.com/robertsdotpm/p2pd Built this recently with it: http://ovh1.p2pd.net:8000/servers (server monitor for public STUN, TURN, MQTT, and NTP servers. Only checks every 4 hours to avoid spamming them though.)
Pretty much finished my photo gallery app for Windows -- https://github.com/Bloomca/Piktosaur. It is a pretty standard gallery viewer, the main feature is that you can point it at any folder and it will recursively search nested folders for extra images, e.g. an external hard drive.
Really happy with it as I wanted exactly that for myself.

The next idea I am going to work on is the audio player. I already wrote a Rust library to read TOC + raw track data from audio CDs (https://github.com/Bloomca/rust-cd-da-reader) and a CLI tool to do so + convert to FLAC and embed metadata from MusicBrainz (https://github.com/Bloomca/audio-cd-ripper).
I've been researching this topic and while my background is related to digital signal processing, I think I will use a library, there seem to be too many edge cases to work with WASAPI and such directly.
I just launched a 10-Bit Video Thumbnail Provider for Windows.
Windows does not natively support rendering thumbnails for 10-bit videos, which are commonly produced by cameras like the Sony A7IV.
When I started working on a short film the video clips were piling up on my hard drive. Opening them one by one to find what I was looking for was tedious.
I could not find a reputable solution to this problem, so I started a company and built one. I went through the process of EV Certification to have the installer and executable code signed.
I hope to be in the Microsoft Store soon.
I'm also building other utilities with similar purpose.
I'm building a Jellyfin client focused on music using Rust + GTK:
https://github.com/Fingel/gelly
I've been enjoying rebuilding my music collection from both old hard drives and ripping old CDs. Jellyfin is great but I wanted a native application focused on music, not video. Thus Gelly. It's been really fun to work on.
I am working on my own Lisp-like language (cliche, I know). Goal is a hybrid. Syntax is a bit more Clojure inspired, but want to emulate the interactivity of SBCL once I am done.
And the other goal is minimal dependencies. The only bootstrapping stage is a very very small core in Common Lisp + FSet but could also be replaced with other languages, and then using that subset to bootstrap the rest.
There is absolutely zero claim to be highly performant, it is more of an educational experience.
All of it is done via literate programming in org-mode. So far it's working pretty well, but will have to see how that approach works if the project grows.
OOI how does the org-mode dev work? Are you tangling and then compiling in a hot-reload loop?
So far it works pretty good. Minor edits I just quickly edit and tangle, otherwise I open the source block in a buffer (C-c '), and from there I can just use the usual C-c C-c shortcut to send it to the REPL.
But as the first stage bootstrap in CL is mostly done at this point, I have to hot-reload anyway.
At some point it might be nice to have my own REPL running in Emacs, but that is a worry for way later when I actually get something usable. For now this is purely for personal entertainment.
I'm working on a K8S hosting solution that just gives the user a simple Kubernetes cluster. I (or we) handle the compute, (networked) storage and ingress hosting for you, and the cluster provision time should be within minutes.
You just need to pay for a fixed monthly upfront cost rather than PAYG, giving small developers a good save of their money.
In other words, this is similar to self hosting with K0S/K3S/OpenShift, except you don't have to own servers to begin with, in other words, it is a little similar to serverless K8S.
Well, all you those you can actually do with a VPS today, heck why do I have to do it if EKS/GKE/LKE/OKE/DOKS exists? That's because it takes a lot of time to properly setup VPC/EBS/S3/EC2, you need to pay an insane amount of premium and overheads to those while an ordinary user just don't want to hassle too much.
I want to undercut the big clouds by saving people's money and time. I have had enough of seeing a ludicrous EKS billing. I just want K8S to be the control panel of everything.
Deploy, run and scale later, simple as that
This resonates with my experience as a small startup dev. I wouldn't mind bringing my own servers for running my apps but for k8s I need at least 3 control nodes in each cluster and I need multiple clusters to cover different parts of the world. All those control planes are idling most of the time but cost money and effort to keep them alive. I'm sure those could be shared among dozens of users. Is this something you are going to support? Or I'll also have to rent the worker nodes from you?
You rent the compute, storage and network from the worker clusters at a fixed monthly price as one budget package, just like how you buy VPSes back in the days (think EC2 Lightsail or Linode, except now you just have a K8S context). You can choose multiple geolocations, but I'm still looking for a successful lab simulation first.
Right now I'm hosting my own test cluster under my bed so I can't show it.
You don't have to manage CNI, CSI, Linux kernel, etcd. You just need Kubernetes app development knowledge and that's basically it.
Now I'm still thinking about how to get live migration and failover working, so it is going to take a painful while...Kata Container doesn't support it out of the box but Cloud Hypervisor does
Link? :)
No link yet as I'm still just a solo dev, the (hobbish?) project is crawling very slowly, but I have the general architecture in mind. I need to get the frontend first.
I tried to submit it as a startup project last year but the feedback isn't great, I want to have something polished first before making it public
I'm resurrecting peer-to-peer Matrix (https://arewep2pyet.com) thanks to the Dutch government, who started funding it in October.
The main question is which P2P overlay network to use, if any: the prior incarnation used Pinecone (a variant of Yggdrasil), whereas this time we're pondering keeping it simpler and more scalable and using Matrix itself as the backbone to connect together smallish local P2P meshes - so by default you try to route via Matrix, but failing that you look on your LAN or BLE to see if you can talk directly to whoever you're addressing. Time will tell if this works :)
If you are open to suggestions, libp2p has a good amount of sdks for several languages and you can integrate kademlia for peer discovery
We are open to suggestions :) And the very first generation of P2P Matrix was indeed built on libp2p (and Protocol Labs led Element's Series B). However, the thought experiment here is whether we can get away without a full global P2P overlay at all in the interests of keeping it simple & stupid. We might well end up back at libp2p tho!

Currently working on getting back into a fitness routine. I got into this habit of hacking on side projects in my very little spare time but I have realized taking care of my body will pay off far more than any project
20 minutes a day is all it takes. Don't even think about it - just do it. After a couple of weeks you'll wonder how in the world you ever lived without exercise -- trust me on this one :)
All the best - the best project to work on! I recently tested a walking pad with a standing desk at my friends place - I was surprisingly productive being able to walk while using the computer. Will be investing in a standing desk and walking pad for my home office.
Today I'm hacking on automate-terminal, a command line program and Python library that abstracts the various terminal emulator automations (iTerm2, WezTerm, Kitty, tmux) into a single API. Mostly made for use by other tools. https://github.com/irskep/automate-terminal
sounds interesting. what was your first scenario when you thought, “Baam! I need to automate this, and I'm going to do it right now!” ?
Working on a binary that will instrument every Java service running on Linux host machine with OpenTelemetry Java Agent.
Kinda like this (https://github.com/open-telemetry/opentelemetry-injector) but with support of having multiple service name for different services. This includes tomcat, normal systemd services and also services running inside docker containers.
EDIT: I am popping my cherry with this comment on HN. Been a lurker since past 2-3 years.
I've just released my beta of FURS.
FURS does for Forth, what headers do for C, namely provide all the embedded configuration information inside a Cortex-M MCU, for the up to 100 inbuilt peripherals.
Without this data, neither C nor Forth (or any other language) have any clue about how to use the peripherals.
FURS does this by intercepting the Forth user source as it's uploaded to the on-chip compiler and transforming it into language the MCU inherently understands.
The Forth user source code is not altered in any way.
I've used the Fossil DCVS for the entire FURS project so that all the flowcharts, pictures, code, user doc, trouble-ticket, wiki ... everything is contained in the ONE FILE, under 5MB.
This one file gives you a web server so all you need is a browser to easily view all the above from the main menu.
Howto: https://sourceforge.net/projects/mecrisp-stellaris-folkdoc/f...
I'm working on Pocketdata - a personal, private AI data plane.
The idea is to take boring components: PostgreSQL, Bifrost (LLM gateway), Open WebUI, LanceDB, Agentgateway (MCP and OpenAPI gateway) and deploy them in Fly.io. One Fly.io "org" per user. The closest equivalent is blaxel.ai, but it caters for AI SaaS startups, not individual customers.
The combination of the fact that Fly secrets are visible only from within the apps, distroless containers, and transparent data encryption for PostgreSQL assures that the service (Pocketdata) provider cannot access their data, only the infrastructure provider (Fly.io) theoretically can, but practically speaking, this gives an extremely high degree of privacy assurance.
The latest update on the project: https://engineeringideas.substack.com/p/tasklet-is-the-o1-mo...
Hey! Your project looks very similar, from a conceptual point of view, to what I'm doing with https://github.com/superegodev/superego. Would you like to have a chat about it? Email in my profile, if you're interested.
I've been wanting to learn more embedded type projects, and I've been snacking too often so I've been building a box that will only open on the weekends.
I got all the components, tested it on a breadboard, learned to solder and now I'm working on the 3d Print to enclose everything.
I actually just did a test run to see if my current 3d design would fit my PICO board, and it fit, but not that secure yet.
Im a developer but never worked this close to metal, so I've been so happy with how it's been going so far, making me real proud of myself.
Comment was deleted :(
Great project, hope you enjoy (not) using it!
Dog enrichment calendar - I have a lot of different types of treats, toys and activities that I'd like to do with my dog but I fell into routines and just gave him two or three toys and treats on repeat. So I'm building an app where I'd be able to configure an inventory of all the treats and toys I own and the app would remind me to use a new toy or treat every day, to minimize repetition. You'll also be reminded ahead of time for toys and treats that require preparation

This is a pet project for myself. I love listening to online radio while at work, helps me focus. But I didn't really click with any of the current selection of web apps out there so decided to build one myself.
It uses the great API available at radio-browser.info for all the radio information.
Been using it as a way to learn how to market a website as well. Learning a lot.
I welcome any constructive feedback.
Very cool, will be using this.
Would suggest that you filter out any radio stations where the URL isn't working if possible.
For example I filtered down to "United Kingdom" and then "bass" - 3 of the 6 worked and would rather see ones that are active.
Also if possible to apply the country filter within the search bar, took me a second to realise I had to open the filter for country, select that, then go back to my search.
When clearing my search of "Bass" in the example above, it reset the search to default (didn't have my country filter) even though the filter was still applied when opening the filter section.
Super easy interface to use though, really well done.
Hey thanks so much for checking it out.
It is annoying when some of the stations don't work. I've done an initial try at filtering them out without much luck but will try again.
Good idea about the country filter.
Thanks for the feedback really appreciate it!
Fun!
Thanks glad you enjoyed it!
I've been building a Decentralized Database built on top of syncing CRDTs, and recently got it to a point I can demo. It's definitely in a "proof-of-concept" stage though, known security holes and all.
I've been focused on building out the featureset and keeping everything unstable instead of trying to finalize each piece as I build it. It's the opposite of how I normally build things but I think it's been working pretty well for this.
I've written about it a few times, most recently "Using CRDTs + Sync as a Database" - https://jackson.dev/post/crdts_as_database/
Really cool, thanks for sharing
I'm working on Solitairle – a Yukon solitaire game where every board is guaranteed solvable: https://solitairle.com
Why? Most solitaire apps frustrate players with impossible games or endless randomness. Solitairle is designed for people (like me) who want a satisfying win through skill, not luck. Every day brings a new, solvable challenge, complete with helpful tools (back button, dead-end warnings) to keep it fun and frustration-free.
I’m especially interested in feedback from people who:
Enjoy casual puzzle games but get discouraged by unwinnable setups,
Value clean, minimalist interfaces without ads,
Have ideas for daily challenges or fun player stats.
Would love your thoughts: What frustrates you most about digital solitaire? What would make you want to play daily?
LINOG.ph is a live earthquake tracker for the Philippines.
The Philippines deals with thousands of earthquakes a year. Whenever the government volcanology and seismology department detects earthquakes, they post it on their official website.
When a major earthquake happens, a huge number of people try to visit the site, causing downtime for up to an hour.
LINOG.ph caches earthquake data from the official government website and the U.S. Geological Survey site, and makes them highly available to the public.
I built this after seeing friends and family donating and providing support for affected families after a major earthquake in Cebu. This was my way of helping out.
Two super typhoons have hit the Philippines in the past two weeks, so I'm also considering adding in typhoon tracking.
Why doesn’t the government put Cloudflare or something in front of their site?

I’m working on a quantum simulator written in C++ from scratch. I’m not using any external library, so I had to implement everything from the lazy eval structure to the eigen solvers and so on. It’s still very a WIP, but here’s the repo: https://github.com/braketware/hilbert-qusim
Any feedback is welcome!

I've been working on Tech Talks Weekly which is a free weekly email for software engineers who want to keep up with new conference talks and podcasts without drowning in YouTube/RSS feeds.
Every week I pull together all the new talk recordings from hundreds of conferences (Devoxx, KubeCon, PyCon, QCon, LeadDev, dotJS, and many more) as well as podcasts. I highlight a few must-watch ones with short summaries, then include a list of everything else uploaded that week.
It started as a personal project to fix my own messy YT subscriptions, and now 7,000+ people read it. I also publish fun extras like “Most Watched Talks of 2024” for Python, Java, Rust, etc.
If you watch engineering talks, you might find it useful. I’d love to know what you think!
There are many language-learning apps, but almost none that focus on improving conversational Hindi for kids.
Made this web app for my nephew, based in Singapore, after watching him struggle to find anyone to practice Hindi with outside of family calls (since most of his friends are Chinese). The idea is to have a 24x7 partner to speak with Hindi and make it fun. This can complement the formal Hindi classes that most kids of Indian diaspora parents take.
My nephew started using this and is enjoying it!

I have always wanted to learn Rust, but was too distracted to get started.
So, I started working with Claude on building a postgres database replication application. I'm learning Postgres internals as well as how brittle database replication and subscription can really be. Although this is for Seren, you can replicate between any PG databases. https://github.com/serenorg/postgres-seren-replicator
Big learning: Claude Sonnet with Rust is massively productive. I'm impressed, but code bloat is a thing.

I'm working on boiling the ocean - we're building a new CRM to compete with some of the big players. I tried very hard to avoid doing this, but I've helped enough business owner friends set up CRMs to realize there's MUCH to be desired. My goal is to create a CRM that people rave about - something that is very rare. Pretty much everyone I help views CRMs as a necessary evil. Our bold challenge is - can we make a CRM that is delightful to use?
Of course we have to slap "AI" on it in this market, but we plan on adding AI features that are actually thoughtful and not just a glorified chatbot.
Sounds interesting! As someone who works in Revenue Operations the CRM space is ripe for disruption, especially around using CRM data to help sales teams explore the data.
I vibecoded a POC of what something I think would work (around the latter part around exploring the data). Need to complete it and start testing it.
Thanks! I totally agree. It starts with getting the basics right. I think this is where most CRMs get it wrong - getting users to correctly enter and maintain clean data is a challenge. We're trying to build smarter schemas for contacts, quotes, sales, etc. but we're also making a really intuitive UI for easily updating information. Further still, we're trying to automatically fill in data for the customer. Many fields can be automatically inferred based on the context of a deal.
Once we get this right, I think the next step is exactly what you said, building really good tools to explore the data. Making it easy for non-technical users to run machine learning on their data to make business decisions or see cool visualizations. We realize that so many of our customers want to know this stuff and have no way of getting at it! We've got a lot of ideas for both visualizing and analyzing the data. I think there's a ton of potential for cool things here. Heatmaps, spiderwebs, interactive charts, etc. Stuff that brings the data to life. One of the common asks from some of our early customers is a heatmap of the world to visualize their sales/reach and see changes over time. Visualizing progress per sales region, etc. I think sales especially has a lot of opportunities for better lead generation and qualification as well.
i'm currently unemployed but i have experience as a CSM and account manager for multiple companies (all have used Salesforce) if you ever want feedback or bounce ideas.
This would be awesome, we're in hardcore MVP build mode right now - when we get closer to launch I'll hit you up.
I'm a little delusional, but I think there's ground to steal back from Salesforce. Most folks I talk to hate how complicated Salesforce is (one even calls it Salesfarce). I've heard a story or two about smaller companies trying to adopt it and wasting a hundred thousand or two implementing Salesforce only to have it never get used. On top of that, you need to train your employees to use Salesforce effectively.
The key is simplicity, building a CRM that anyone can instantly understand just by looking at it. This is insanely hard but I think we'll pull it off. I'll show you more what I mean when I reach out. Thanks!
I'm working on Volt-Test, a performance testing engine I started building after repeatedly debugging concurrency and race-condition issues in Laravel/PHP applications.
The idea is to bring something like k6 to the PHP ecosystem:
A Go-based load-testing engine
A PHP SDK that lets developers write performance tests inside PHPUnit
Assertions for latency, error rates, and business logic
Can spin up local servers and run in CI/CD
Working on distributed mode to scale tests across multiple nodes
Currently building the cloud version so teams can run large tests without managing infrastructure
For Laravel developers, I also released a package that integrates Volt-Test directly into the framework:
https://github.com/volt-test/laravel-performance-testing
It supports automatic route discovery and makes it easy to write performance scenarios using familiar testing patterns.
Docs + examples: https://php.volt-test.com
If anyone here has experience building or running distributed load-testing systems, I’d appreciate any feedback or pointers.

I'm working on a JSON schema discovery tool, JSONoid[0]. JSONoid can discover many more features of JSON Schema than existing tools such as regular expression patterns, formats, and dependencies. I'm also working on integrating this with some past work I've done on using LLMs to augment JSON Schemas[1,2].
There are a number of use cases for such a tool. One is for helping data analysts who are handed a pile of JSON documents to be able to more quickly and effectively craft analytics pipelines for heterogeneous data where just inspecting a few documents isn't sufficient. Another is to help automate API specification generation and regression testing. Definitely interested in any feedback.

For the past 2 months I have been doing a heavy deep dive into image generation and image generation editing capabilities. This then had me discover that you can generate storyboards for short stories, and automate the creation of these as videos with video generation models. This is a topic that interests me heavily, and as such I am now building my own workflows around that. I am documenting the entire journey here:

It's not something I am looking to commercialize, but I actually did drop out of film school (with semesters in creative storytelling) to pursue software 15 years ago. And I feel like this will open up a whole new way of visual storytelling as well as personal and product branding. I have gotten quite some emails about it, from interesting people in different industries, as some more strongly worded (not so nice) emails from someone in the VFX industry since I started. Its by far one of the most interesting tangents I have ever went on.
A low(er)-level agent runtime: https://github.com/smartcomputer-ai/agent-os/

I've been working on two game development projects for the past couple of years.
One project is for building rhythm games in multiple game engines and multiple platforms. Currently, it works in Unity, Unreal, Godot, SDL (or any C++ game engine), and MonoGame (or any C# game engine), and runs on Windows, macOS, and Linux. I'm working on adding Love2d (or any Lua game engine) and Bevy (or any Rust game engine). I have a few local prototypes of it working in Unity and Godot, but nothing public yet. Still trying to figure out what kind of game I want to make with it.
https://github.com/neogeek/rhythm-game-utilities
The other is a general purpose game engine in C++ with SDL. It's far enough along that I'm building games in it, but it's more of an exploration into how games are made than a replacement for Unity or Godot. I suppose it could be eventually, but I'm trying to be realistic with what it can do. One thing I'm pretty happy with regarding this engine is that one of the demo repos will automatically build to WebGL and publish to itch.io when changes are pushed.
I’m building A2Fusion [1], a dual RP2350 expansion board for the Apple II to provide, storage, hdmi video and other functions in one card. The PoC is currently a big mess of wires. Waiting on JLCPCB for first prototype boards.
[1] https://m.facebook.com/groups/5251478676/permalink/101664026...
Assuming that you're in the US, what's been your experience with JLCPCB recently re:the tariff situation?
I'm getting ready to have a couple prototypes made soon and trying to decide between getting boards made at OSHPark and hand-stuffing/reflowing myself or having JLCPCB do all of it.
Timing seems to be about the same (but just in production now). But tariffs/taxes were 55% of merchandise cost. DHL is expensive too, $52 for 10 boards (shipping to Cali). I haven’t used OSHPark.
A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use. There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used.
When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use.
My Civil 3D plugin will:
1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent.
2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access.
If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training.
As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it.

I was able to get the original 15khz CRT monitor up and running by recapping the board. I decided that the control panel was unsalvageable, and insufficient for what I wanted to do, which was make this cabinet compatible with most any game that would have run on a cab like this.
I decided to use RGB lit buttons, so I could change the color's depended on which game was loaded. I used an ESP-32s2 to emulate a keyboard, and accept serial messages from the host computer that changes the button colors.
I also incorporated a Stream Deck in the control panel for auxiliary functions. I was able to write a node application to run the stream deck (with the help of a library) since there is no OEM software for linux.
By far the most challenging part was getting a suitable signal to the CRT. The first thing I tried was using the Raspberry Pi's GPIO pins through a VGA666 board, but this limited my colors to 16bit, which makes 3d games look pretty awful.
Next I tried using a downscaler. This got me 24 bit color, but resolution switching doesn't work with this method.
I'm trying an AMD system now. Apparently the linux driver lets you set custom resolutions, and output 15khz (and 25khz for that matter) right from the VGA port.
I plan on doing a writeup after I near completion.
I'm working on Argon Chess, a deterministic chess variant with some degree of cheat resistance (hard to describe to chess engines like Fairy Stockfish) and tons of variety.

Thanks for the link to that 20 games challenge. Godot is fun and something I want to get back to eventually!
I'm working on 3 projects right now:
---
Backdoor: https://github.com/tanin47/backdoor
A self-hosted database querying and editing tool for you and your team. Modern and elegant UI. Supports Postgres and ClickHouse. It can be embedded into any JVM app or runs as a standalone.

That's for HTTP/S and related, as parent said his is for BGP which is a completely different protocol
I've been studying wine and was a bit frustrated with the wine note taking apps around, so I've been building one. It allows to:
- Scan wine labels (it analyzes the label automatically)
- Add structured or unstructured tasting notes
- Create lists (shared or not) to keep wines organized
- View information about the regions/grapes
It's called Cork Club: https://corkclub.app/
https://gametorch.app/sprite-animator
Create video game sprites and animations via prompts.
Pretty excited because I've started to get high volume, repeat customers.
Ahhh this is exactly what I'm looking for! I don't see any pricing on any pages. Would love to know how much this costs (I don't know what 455 diamonds is worth) as there's a few sprites that I'd love to animate and use in my app.
Not a fan of signing up before seeing how much I'd have to pay. The examples look great though.
1 diamond = 1 cent
Prices are about to drop dramatically. Many of the models dropped >80% in price since initial launch. Any time I have a reduction in cost, I pass the savings directly on to users.
> The animations cost $0.32 ( 32) each.
Not sure if you just added this in or I overlooked it, but exactly the kind of transparency I love. Will give this a try.
--
EDIT - Did an image generation using the OpenAI 4o model, then ran through the lowest quality animation. This is awesome and first pass is very strong and usable (around 100 diamonds used).
I look forward to seeing prices drop more and the asset pack area fill up. Keep going man, really awesome stuff.
I've tried making game tiles and sprites with Craiyon, which works surprisingly well now. But I always struggle with consistent style, scale, colors. And if I want a border around buttons, it's better if I make it once and apply it myself in photoshop, because the AI will change it slightly every time I ask for a change to the sprite contents.
A RAG Boilerplate with Extensive Documentation
I open-sourced the RAG boilerplate I’ve been using for my own experiments with extensive docs on system design.
And I have bunch of LLM+RAG blogs I post frequently last 2 months : https://mburaksayici.com/blog
It's mostly for educational purposes, but why not make it bigger later on? Repo: https://github.com/mburaksayici/RAG-Boilerplate - Includes propositional + semantic and recursive overlap chunking, hybrid search on Qdrant (BM25 + dense), and optional LLM reranking. - Uses E5 embeddings as the default model for vector representations. - Has a query-enhancer agent built with CrewAI and a Celery-based ingestion flow for document processing. - Uses Redis (hot) + MongoDB (cold) for session handling and restoration. - Runs on FastAPI with a small Gradio UI to test retrieval and chat with the data. - Stack: FastAPI, Qdrant, Redis, MongoDB, Celery, CrewAI, Gradio, HuggingFace models, OpenAI. Blog : https://mburaksayici.com/blog/2025/11/13/a-rag-boilerplate.h...
For my work I've developed a web-based Monte Carlo simulator with a visual, node-based editor for building supply chain models. Last week, I started making it available for everyone.
You can have a look at https://simcarlo.com. The tool allows you to see the full spectrum of potential outcomes instead of just a single guess.
A kernel extension-less sshfs for macOS. I tried using FSKit and got halfway before I felt too constrained by the extension security model (must be app sandboxed, must be approved by the user in system settings). Now it’s just a standalone command line binary that doesn’t require any special permissions since it proxies NFS to SFTP. Everything “just works” and performance is reasonable
Interesting... the way I workaround'd non-macos-native-sshfs is by using docker and mounting a local folder, do you plan on publishing your tool?
Absolutely: https://github.com/jabedude/sshfs
I built a tool to generate a PDF for each row of a Google sheet. For example, you can generate 100 personalized PDFs (like certificates) for 100 students listed in a Google Sheet.
Once you sign up and connect your Google sheet, it generates a template (using AI) based on your data, which you can edit in a Notion-like editor. You can then generate PDFs for your entire sheet or a for a range of rows.
Some use cases I'm seeing:
* Certificates for students or course completions
* Monthly invoices for all your clients (https://sheetstopdf.com/use-cases/business/invoices)
* Personalized reports with individual client data
* Event tickets or conference badges
* Contracts, offer letters, or any personalized documents
* Really anything where you have rows of data that need to become individual PDFs
Would love to hear what you think or if you have use cases I haven't thought of yet!
A modern day mail merge.
I recently started a local chess club, and did a quick search for software to use to allow us to manage the club, but couldn't find anything open-source/free.
I wanted something that would allow us to record members, games, etc., and also allow us to be assigned a local club rating. Anyway, after doing some searching and only finding paid software, I decided to just build something. That lead to https://openchessclub.org
You can check it out on GitHub: https://github.com/OpenChessClub/openchessclub.
I plan on building a QR code generator that allows club members to check-in during meetings, which will then allow players to be matched, and some other features, although it is primarily aimed at smaller chess clubs, so don't know how far it'll go.
I’ve been working on MemoryPlugin (https://www.memoryplugin.com), a tool that adds long term memory across AI tools
Lately I’ve worked on a chat history based memory feature that can recall information from every conversation you’ve ever had with ChatGPT and Claude. It’s been particularly useful and also technically fun to implement. Speed has been very important as I do just in time summarisation and a multi stage RAG pipeline, and most LLMs have unacceptable performance. I ended up going with GPT-OSS on Groq due to its ultra low latency often completing full generations before Gemini or ChatGPT APIs return even the first token.
The ability to recall details from conversations going back years makes tasks where I want personalised plans or feedback like 10x more useful, at times I get the AI to ingest tens of thousands of tokens of context to help me better.
The Board: A feature board that vibe-codes the top voted feature into itself every night: https://theboard.stavros.io
very surprised I haven't seen this done before - cool idea!
Probably because security nightmare
I’ve created a small command-line tool that generates a hash-based, human-readable list of git repositories and data folders. Its purpose is to capture the exact state of all projects and files in a single plain-text file.
I built it because I work across multiple machines and often worry about which projects are on which computer or whether I’ve left any files in unique locations. Now I can diff the summaries between devices to see what’s out of sync, which repositories have uncommitted changes, and which folders have been modified.
I avoid using cloud sync services, and most of my files are already in git anyway. I find that having clear visibility is enough, I just need to know what to commit, push, pull, or sync manually.
I would be glad if it proves useful to someone besides me.
I am working on https://embedhub.com
I am building better dev tools for firmware and PCB developers.
For example, we have GitHub Action workflows that allow you to push builds to the connected EmbedHub project. Your EmbedHub project has fine grained release management - so for example only the git tagged releases will be shared with the customer, but the testing/QA team will get access to builds from regular commits on branches as well.
I am also building a physical device (called HAL) similar to the now discontinued EtcherPro[1] - which will connect to your EmbedHub account and have access to your releases. This will let you offload tasks like long term testing, mass flashing and provisioning of devices, and more.
A new ping pong paddle design.
My backhand is OK but my forehand sucks. Grip styles for standard handles usually end up favoring one side or the other. I'm making a handle shape that's easier to get the blade angle right on both sides. Hopefully a couple more iterations on the 3D printer and then I can have a functional prototype made.
Building https://www.hessra.net/, an authorization system based on the Biscuit token format (decentralized, signed, and attenuable). The goal is to push beyond JWTs and Zanzibar-style policy engines by giving every machine-to-machine request its own embedded, verifiable authorization logic in a small capability token. These tokens can be delegated, restricted, and verified locally with no extra network calls required after getting the token.
Early use case is replacing API keys with identity tokens that expire, delegate, and prove possession and then can be used for easy step up to fine-grained authorization. There's some pretty interesting authorization stuff you can do, like having multiple parties sign off before a token is valid or requiring a series of micro-services sign a token for it to be valid.
I made an LLM-assisted DnD character sheet tracker! It's up here:
And the repo is here:
https://github.com/igor47/csheet
If you play DnD, I would love feedback! Feel free to leave it as GitHub issues or discussion.
If you don't play DnD, you might still find the repo interesting. It's hono on bun, I render jsx server side and client side is all htmx. I use vercel's ai toolkit for the LLM interactions, which are super fun and work really well. I think this is a great use for AI actually. I've structured the code so the same services can be called either by the user via forms and routes, or via LLM tool use, so for every action in the code you can do it via either LLM or "manually".
The LLM usage is fun and interesting. What model are you using, and how much customization are you doing to integrate with the app and maintain character?
I suggest adding an export function to make the characters more portable. Maybe export to PDF as well as JSON.
Using haiku 4.5 right now. I think I could get away with even smaller models. The prompt is here: https://github.com/igor47/csheet/blob/main/src/ai/prompts.ts and my tool use is here but it's really all through the code: https://github.com/igor47/csheet/blob/main/src/tools.ts

It is a recipe app but better, and way more technically capable than anything out there. The goal is to make the best recipe app ever made. With bulletproof easy to follow recipes and smart features to make cooking simple. Everyone deserves good food at home, but good food is complicated and time consuming. An experienced cook can make good food quickly, cheaply and make it look easy. The idea is that Kastanj will have the knowledge you don’t so you can cook like a pro without having to spend years learning everything.
Backstory: I have a note where I write down practical problems I experience in life. I noticed over time that the amount of notes related to food and cooking was growing faster than anything else. I then began searching for a solution. I tried over 50 recipe apps, always the premium version if possible. There are some good apps out there but even the best ones only solved something like 50% of my issues. After enough frustration and search I just decided to start working on my own app. That was 4 years ago... It turns out that solving some of these problems where technically complicated to do, so now I understand why no other app could solve my problems. None the less, after 4 years of work, starting over from scratch 5 times, I have now landed on a solution that technically solves all my problems.
Going forward: Now I am working on filling the app with data and make it easy to use for normal humans. I am on purpose limiting myself to only perfecting the core functionality of what a recipe should be. I intend to launch sometime in 2026. The UI will be small and limited at first, but it is perfect for my needs. Therefore I hope it will also be perfect for someone else. Over time I will enable more advanced functionality and build it out based on user feedback. I know the backend can support 100% of my needs, but I don’t want to make it bloated. Therefore the UI is on purpose focused on only the most important things and then we will build it out with time, together with the recipe creators and end users.

Just launched last month.
I have been working on implementing iCalendar/RFC5545 in Emacs Lisp. I recently submitted a large patch and hope it will be merged in the next couple of months:
https://mail.gnu.org/archive/html/bug-gnu-emacs/2025-11/msg0...
This will add an iCalendar library to GNU Emacs, allowing packages in core and third-party packages to work with the format. More on the decisions I made and what I learned here:
I’m building an AI-powered fashion search engine that helps people find clothes that actually match their style, fit and price across 1000s of brands and millions of products
Most shoppers spend hours to find the rights product. We’re fixing that with intent-based search that understands descriptions, images and personal preferences.
We’ve hit 25K+ searches in 4 months, growing 50% MoM, and built our own scraping system that makes product data collection 100× cheaper than existing tools.
Still early, but live. Would love feedback on search quality and result relevance.
PS! There are some products out of stock, this is expected, fixing it right now.
Really cool. Found myself a specific jacket that I have been looking for a long time and made the purchase. 25k+ searches in 4 months. Which markets you launched in or marketed so far? How you chose where to start?
pretty damn cool. tested it with some still frames from movies and pinterest boards and it found most of the things.
[stub-for-green-comments]

Thanks! We’re adding millions of products and thousands of new brands over the next few weeks. We’re also exploring second-hand listings.
Comment was deleted :(

We differentiate by focusing on intent, not keywords. The giants return results based on matching terms. We return results based on understanding what the shopper actually wants to do, backed by curated, high-quality data.
[dead]
Biggest challenges in search relevance are: - collecting and maintaining a large, clean, diverse product catalog (up to hundreds of millions of products) - actually understanding what users mean (not just what they type) - giving them ways to refine vague searches.
Skip any of these and even the fanciest ranking algorithms feel useless. Helping users bridge that gap is where relevance actually clicks.

I've been working on an open-source containerized agent framework called Capsule Agents. Its built around 3 key ideas I've dealt with inside the agent ecosystem
1. Agents become far more capable when they have access to a CLI and can create or reuse scripts, instead of relying solely on MCP.
2. Multi-agent setups are often overvalued as “expert personas” but they’re incredibly effective for managing context, A2A is the future.
3. Agents are useful for more than just writing code. They should be easy for non-engineers to create and capable of providing value in many domains beyond software development.
If that sounds interesting take a look! https://github.com/brycewcole/capsule-agents
My friends and I have been hacking on http://dateit.com for a while. It's an event planning app (works best on iOS and android, but there is a web app) with lots of fun features:
- Calendar sync
- Photo upload
- post/comment/reactions
- Recurring events
- SMS notifications
- Greeting card maker
(and a lot more)
It's grown into something much more than our original idea. Most of the features are free and we have a fair pricing model that doesn't nickel-and-dime you like many of the competing apps do. Would love your feedback!
I've been working on a factory sim game for some time now and I'm finally getting to a stage where I might be comfortable enough showing it off soon and maybe even try my luck with some sort of crowdfunding.
Where do I sign up ?
I duct-taped together a quick website[1], you can sign up for the mailing list or the discord if you're interested... Or just check up on the website in couple of weeks.
The "follow KeroPunk" part renders a bit wonky on mobile (you have to scroll inside the pane) but ... I signed up. :D
If you uh... need any early testers, LMK.
Thanks :) I'll definitely be sending out an update soon... And yeah, I haven't really mobile optimized the site yet.
I'm building a Meetup.com alternative, of sorts - https://www.radius.to/
It's intended to be a sort of social network focused on IRL groups/communities and finding others with the same interests in the same area, and just building local communities in general.
It's currently still a part-time venture, but I'm planning a launch on HN soon to get input/gauge interest in the latest iteration. FWIW, I posted the initial version on HN just over a year ago and got a ton of amazing feedback, much of which I've incorporated over the last year - https://news.ycombinator.com/item?id=40717398
We’re building Ward, a security browser extension that uses Gemini Nano, an on-device LLM, to scan for phishing, scams, and other threats from the DOM.
Think of an antivirus for everyday web users, like young children, older adults, and less savvy individuals.
We recently participated in the Google Chrome Built-in AI Challenge 2025 and have submitted to the Chrome Web Store.
We’re looking to meet people who may know someone Ward is good for and would want to provide feedback. Alternatively, we’d love to chat with any IT Managers/Directors of Security/Google Apps Admins who would be interested in piloting us as an anti-phishing enterprise solution.
You can DM or hit me at fitzgeraldcedric(AT)gmail.com :)
You should probably make a version that is usable as an email filter plugin for mail servers
Ooh, good idea. It started as a question: "How do we make this thing the most private?" and the obvious answer was using offline local device LLMs (e.g. Prompt API/Gemini Nano).
Will poke around and see if there's interest here, thank you!
I built a website (https://hpyhn.xyz) for hacker news users for reasons:
1. hn comments are valuable, I've spent a lot of time going through hn comments. I think there are valuable comments buried in the threads with fewer points, so it's not enough to just read top3 threads.
2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs.
3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference
so I want a tool to save my time while not missing out too much on hn
I'm glad to hear feedback
I tried to register, and clicking on register button did nothing.
Thanks for feedback! It's working now.
Any questions we could chat on X @liqilin3
Working on a free alternative to Masterclass - compiled from YouTube clips!
Currently have two binge-able mini courses on How to Start a Startup (could be relevant to folks in here)
Here it is: https://opencademy.com/
I think this is pretty interesting, especially if you could remix courses... like if you had a bread baking playlist and a pizza making playlist. The pizza making course could include or use modules from the bread course as a requirement.
Similar with learning software development, you usually need basic modules like regex or databases before learning more complex skills.
That's a great idea, kinda like the Civilization game series' "tech tree" concept. Thanks for checking out the site :)
Recently launched my free app for gardeners to share plants with each other, Plantshare.
Now I'm working on a few changes to the app, most notable is moving any plants marked as 'for sale' out from the main section because it turns out people are more greedy than I anticipated and it's getting in the way of sharing the free stuff, cuttings etc.
There's also some demand for a web front end so I might work on that next. (currently only android and ios)
I had an initial boom of downloads in South Africa but lately most new downloads are in USA.
I buy and operate e-commerce brands that sell on Amazon, and I'm working on handing as much of the operation of the business off to AI as possible. Doing this both for actual time savings for myself and also as my big-picture eval of new AI models + products as they come out.
I also started a Substack to document it - here's a recent post on using Gemini to screen inbound emails with prospective acquisition targets via a Google Apps Script that evaluates the listings in those emails daily: https://theautomatedoperator.substack.com/p/screening-inboun....
The Daily Baffle, a site with all sorts of daily puzzles including one clued daily by NYT-published constructors.
Can check it out at https://dailybaffle.com
I'm still working on growing the audience. App coming soon!
This is awesome, shared with a few people I know would like this.
Been working on https://usedigest.com
- It's a personalized newsletter for you
- All data aggregated from sources around the web
- News, weather, newsletters, social media posts, reddit, youtube, etc. all appear in your digest.
- Launching a mobile app as well now but this will be slightly different than the web app. It will use AI to automatically prepare your daily digest based on preferences/settings you give it during onboarding. Each day when you wake up you'll receive a notification of digest being ready, and it will contain all the content you care about for the day ahead (meetings, weather, health data, commute data, news, etc).
I still need to go back working on https://www.cinekids.info/ , a tool I made for myself to use before showing any movie to my 4 years old kiddo. It scrapes reviews from some parent friendly movie reviews websites and aggregates them.
I'm also automating more stuff around bookmarks management -> I used to manage an awesome list as a repository on GitHub for myself and over a couple of years there are relatively many stars on this repository. However I lost interest in maintaining this repo manually as I prefer to save my bookmarks on Shaarli. I'm coding a CLI tool to automate the work of syncing my shaarli links to my public "popular" (+500 stars) repo at https://github.com/SansGuidon/bookmarks
Myself and other users complain a lot about the "native" Plex -> Ombi watchlist integration being broken, I coded some sync tool to workaround the app malfunctions, by using Ombi, Plex and TMDB (The Movie Database) APIs and ensure Ombi is always up-to-date based on Plex watchlist. This works very well and allowed me to put a stop to the complains from my family members :-D
I'm also automating most of my email/linkedin interactions thanks to userscripts. And I keep automating more of the work I do around Cloudron, which is a very fun and stable platform to manage apps on VPS without the pains.
A webcam & microphone JS tester library that you can put in front of your WebRTC or MediaRecorder web app to diagnose any possible issues (the presence of getUserMedia, secure context, required devices, policies blocking device access, supported resolutions, etc.). It also primes your users’ OS/browser permissions before they get to the real app.

Meta question:
Is there a cadence for these threads? I had in mind to "be prepared" to post in November's with what I'm working on, but I expected it to come around on the 15th (mid-month).
What I'm working on:
- skuilder - (skill builder) - https://github.com/patched-network/vue-skuilder - an AGPL framework / toolkit for SRS++ based interactive tutoring systems
- https://letterspractice.com - a low cost, hopefully high quality early literacy acquisition app, targeting ages 3-5.
- https://flutor.app - an app to learn the flute
(The proprietary apps are built with the toolkit).
I've struggled to pitch or articulate the vision here, but my latest pithy attempt is: scaling self-actualization by mechanizing the nested loops described by Anders Ericson's 'deliberate practice' - Inner loop: individual learners maximize their skill uptake velocity and performance peak by adhering to domain specific best practices - Outer loop: domain specific best practices get refined according to innovation or serendipitous discoveries from the inner loop (eg, someone is observed to beat out prior best practices)
As mentioned, I'm flat-foot posting here, so the pages aren't all prepped. https://flutor.app/dbg and https://letterspractice.com/dbg show some of the innards. Not linked, but I'm especially fond of https://letterspractice.com/dbg/juggling - the premise here that as child practices the letters, the letters exemplify the principles of effective practice in alliterative skill domains (juggling Js, batting Bs, flossing Fs (it's hard ok?))
I believe it is every other Sunday but I'm not 100% sure.
All-in-one router/nas/firewall/adblock/app server (each piece optional)
Declarative and reproduceable as it is built off of NixOS, but administered through a UI, so the user doesn't have to know this.
All state managed in a backup bundle, so it can be hosted at home or in the cloud.
Goal is to have a box you plug just like a wifi access point into your modem, follow a simple web-based installation flow, then you are running a personal cloud.
Website is self-hosted by HomeFree, but installation instructions are very out of date, which I'm working on right now. There are now installation ISOs that I will soon add a link to.
Manabi Reader: Japanese learning through reading
I recently added FSRS (besides also having Anki integration). Now I'm working on replacing the need for reviewing flashcards by having reading activity automatically mark flashcards (current and future) as reviewed, so that you can get many of your reviews in just by reading native materials that interest you instead of sacrificing most of your study time to contextless flashcard grind.
I'm also working on a manga mode using a new manga OCR tech I have licensed out of academia that is ahead of state of the art alternatives.
This project now sustains my full-time focus.
This looks super cool. I love to see people working on language learning tech. I'm working on a language learning app too but it only really works well for indo-european languages. That said I would still love to collab or talk shop, my contact info is in my bio
Looks good. Hope you'll do an Android version sometime.
It's native SwiftUI and Swift so I want to avoid a rewrite. I am experimenting with porting my Swift code to web via WASM, now that SQLite WASM backed by IndexedDB is usable so I can reuse the data layer too. I'm also evaluating https://skip.tools for running my SwiftUI on Android.
Either of web or Android would be great. Looking forward to trying it once one of them becomes available.
After one of my cyber security research caught some attention in media, am now working on -
Open Source Vacuum Robot firmware
Building https://github.com/openrundev/openrun, a platform for declarative deployment of web apps.
OpenRun runs as a web server, which does GitOps driven app deployments. You can currently deploy apps on a standalone machine, on top of Docker/Podman. Working on adding support for deploying on top of Kubernetes. On Kubernetes, OpenRun will replace your build jobs (Jenkins/Actions etc), CD (ArgoCD etc) and IDP (Backstage etc). The same declarative config which works on a standalone machine will work on Kubernetes, with no YAML to maintain.
A visual editor for creating video games on the browser and on Linux desktop: https://stickyfingies.github.io/g2ngine
I've done this with C++ in the past, but ran into substantial friction with the CMake toolchain, specifically w.r.t:
- cross-platform compilation with large dependencies (vcpkg ports)
- running multiple compiler chains in the same build step
That second point is necessary if, for example, there's some AOT asset processing work that uses a native tool, and you're building for web. Expressing that some targets should use the emscripten toolchain while others should use the native toolchain, and interleaving between them, was a mess. TBF, I haven't done that with cargo or build.rs yet and it may prove to be equally frustrating.
Other features:
- undo/redo using a stack of swappable states
- serialization to disk (native) and LocalStorage (web) with some integration tests in progress but I am not satisfied with the correctness of my implementation: I want to *guarantee* that all information is preserved round-trip, but I also want a Patek watch.
- OBJ, GLTF, GLB models are loaded as "blueprint scenes" which are distinct from the "world scene." I made this distinction at the type-level because "scenes" are groups of entities that use newtype IDs (`LightId(u64)`, `MeshId(u64)` etc.) as primary and foreign keys to refer to each other, and I wanted to make it impossible for an entity in scene A to hold an ID for an entity in scene B. Instantiating a blueprint requires creating new IDs for every object.
- W.I.P. Alpha rendering, depth sorting, overhauling the material system to support multiple shaders (tough) that may be compiled after the engine itself (even tougher, a lot of runtime dynamic state and schema validation stuff), physics, scripting - oh yeah!
- Scripting using JS on both web (runs in browser itself) and desktop (uses a packaged JS runtime `Boa`) but Boa doesn't perform well on desktop in debug mode so I'm exploring other options.
I'm getting back in to audio programming, starting off with Pd[1] and reading Miller Puckette's book[2]. I'm planning on writing some low-level C libraries afterwards, using The Audio Programming Book[3] as a guide

I'm building a tool for managing Google Ads campaing called Rudys.AI:
- Search campaigns: - automatically crawl website, find the offerings and generate new campaigns - Provide qualitative recommendations such as, relevant terms to include/exclude, e.g. including typos as keywords, improvements on landing page
- Shopping campaign: - Smart labeling of all products to allocate the budget among Top performers, Rising and Ghost products to avoid draining the budget. E.g. instead of a campaign with 10k products with one budget , turn it into 5 campaigns with different budgets doubling down on what works.
Feel free to reach out for a demo
I built Arty: https://github.com/vibemachine-labs/arty
It's an open-source iOS voice agent that uses the OpenAI Realtime API (bring your own key).
Current connectors: Hacker News (check demo in readme!), Google Drive, GitHub, and web search.
I got frustrated with the limitations of the OpenAI Realtime Voice iOS app—for example, it can't even connect to Google Drive.
Arty is self-contained except for the OpenAI model and any third-party services you connect to. Uses local tools—no MCP support yet.
If you'd like additional connectors, feel free to open an issue.
This is super cool. I noticed that you mention that you will add MCP support soon. I was wondering, do you think it would be possible to control MacOS via voice, remotely, through one of the available MCP servers that allow MacOS control. Do you think that would be feasible?
yes but ud ideally want ur own high uptime mac mini
Got it. But you could just use it on your MacBook on those occasions where you want to "talk" to your computer remotely to check on some progress it made on a specific job. My use case would involve switching desktops, activating specific windows, and reading their content and taking some action. But depends more specifically on the MCP that exposes that functionality, and not your app. I was asking because you're probably more familiar on how reliable such an approach might be.
I've been building with local AI, on Apple Silicon. It's only 8mb, but runs 30% faster than Ollama.
did you really solo develop this entire application? including dinoki-ai which appears to be SAAS?
I've working on an AI Thumbnail Generator for making YouTube thumbnails and social media images the last few months. https://thumbnail.ai/
Nice work. I am bookmarking this. Looks really good!
Built a web interface for Magic: the Gathering draft pick advice, trained on top player data.
Website: https://statisticaldrafting.com
Turns out to be a small niche, but I enjoy it!
Updating partijgedrag, which is a voting compass based on how parties vote on motions in the Netherlands!
Apart from that I have a personal SaaS idea I want to release soon. Its something that started as a joke but the joke is still not finished
Building an MCP Gateway: https://www.gatana.ai/
Idea came from one of my clients, where they wanted to use AI agents throughout the organization but at that moment there was no centralized governance or security concepts. This pulls everything at one place and tries to solve the security concept with per-user credentials, which can be provided out-of-band through the MCP protocol (generated a one-time link end-user can use to sign in to the underlying MCP server with OAuth or provide API key)
I'm still working on WithAudio (https://desktop.with.audio). A one time payment Text To Speech Desktop App. Because I think everything doesn't have to be a subscription.
In October I finished the PDF parser. It was a big challenge extracting PDF contect with correct paragraph breaks on user's computer locally. I'm gonna write about this soon.
Now I'm working on a web extension that talks to the app that run locally on your system so you can use WithAudio in your browser with very good performance, 100% local and private.
I’m working on a Chrome extension called Console Dock, which adds a floating dev console window directly inside the page. I built it as a fun side project because I often work on smaller screens and hate constantly switching or resizing panels. Still very experimental, but it’s already proving useful for quick debugging sessions.
https://chromewebstore.google.com/detail/console-dock/biplbp...
I used Eruda before. Is it similar?
Looks great BTW. Installed.
Working with a group of friends on a "microcontroller-for-makers" kind of thing called the MakerPort. (https://makerport.fun) Sort of similar to an Arduino or micro:bit, but uses the MicroBlocks programming editor (https://microblocks.fun) created by John Maloney, who was the original team leader for Scratch at MIT for 11 years. The hardware includes an mp3 player, I2C ports, accelerometer and true capacitive touch sensors.
I’ve been working on http://www.13radar.com for the past 4 months, and we launched about two weeks ago. The platform tracks hedge fund portfolios in real-time based on SEC 13F filings.
I’m responsible for product research, analysis, design, development, and promotion. Most of the workflow was powered by AI tools — more than 60% of the research, design, and coding involved AI assistance. Initially we used Bootstrap for responsive design, but later switched to a lighter TailwindCSS framework.
Right now traffic is very low (just a few dozen users per day), and I’m trying to figure out whether that’s a product issue or simply a lack of promotion. Honestly, it’s a bit discouraging, but I’m hoping to learn from feedback and iterate.
Curious if anyone here has experience growing early-stage products with niche financial data — how did you approach the balance between product refinement and marketing?
I finally started modding a total war game (Warhammer 3). I played the series since the very first title, Shogun and I always wanted to improve the control over units and add my custom AI to not micromanage everything, but assumed it would be too time consuming and distracting from my main work. And well, it likely would have been.
But thanks to LLMs, I finally decided to give it a go and got something basic working in a short time, hurrey for AI assisted coding!
Feels empowering to be honest. No idea if I will really implement the main ideas, that I have since a long time, but I know that I can now if I want to.
Working on a CLI tool called xpire which can add expiry dates to filesystem structures: https://github.com/benibr/xpire Idea is to use filesystem specific structures (eg. snapshots) if possible to prevent long treewalks for searching and store the dates in the filesystem itself not a seperate database. It's written in go and currently supports btrfs snapshots and zfs datasets.
I wanted to give anyone the magic power to make himself an FPS game of their place (appart, museum,ect...). Still not perfect but it's light and my 3D editor is simple enough for anyone. - No coding. - And no need for Unity or Unreal.
==> Here is a photo of the Editor : https://ibb.co/FC9Hzj2
==> website with an example of a FPS visit https://free-visit.net
Please be honest, tell me why I don't have traction.
This is a cool idea! So I think, unfortunately, you are competing with automated tools like https://poly.cam/ My cousin-in-law produces music videos, and he'll take a polycam of sports cars (or even people!) and add them to his videos, it's powerful and instantaneous. No 2-3 day wait time.
It's great that you're working on this. If you want to continue on this, I'd consider: - Cleaning up the design of the website-- it looks kind of crappy. Get an AI agent to clean it up for you, it's better to look like "generic professional website" rather than "crappy amateur". - Use the more common words for creating 3d models. A "Visit" sounds like an experience, but what you're really making is a "scene", or a "spatial capture", or a "floor plan". - Maybe try to figure out a niche. Is your niche that people can edit this the 3d object afterwards? Or is the niche integration with video games? You gotta find something that doesn't directly compete with polycam.
Thank you civilian for your answer and hints. It's funny I though matterport was more like me. Because both of us make " virtual reality".
I think You are right It's a bit idiotic from me to be cautious and say 'result in 3 days'. I could say 4 Hours now.
And yes.It's not 100% automatic. I agree, my low point.
Built an in-browser AI managed spreadsheet. https://banker.so/
Too many things I wanted to analyse went to nothing because I was too lazy to fetch information and the put it inside a spreadsheet cell by cell. So I developed this to help me extract docs into spreadsheets while also having access to the web.
Now working on a vibe-coded version of it where instead of showing a spreadsheet, it will be able to generate data-focused tiles and apps
I was working on a iPad-focused Dungeons & Dragons app focused on the Dungeon Master called Campaign Codex but I got a little bored with building CRUD apps.
Decided to pivot and start learning about databases and their internals more. Currently pulling down Clickhouse and reading some code along with the reading the book Database Internals by Alex Petrov.
So I'm technically not "working on" an app...I am working on myself to branch out and attempt to specialize a bit more as I progress in my career.
Any advice/papers/books to read is very welcomed!
https://github.com/dmjio/miso-lynx
Building native applications for iOS, Android and Huawei devices in Haskell.
This sounds very interesting. You say “native” but miso generates JavaScript, right? I’m not familiar with mobile development. Can you run JS natively on mobile devices?
Yes, miso uses the JS backend in GHC, and mobile phones have embedded JS interpreters (e.g. JavaScript Core). These interpreters can access native libraries to draw native views, or access native device APIs.
Projects like lynx and react-native automate this process using something akin to node-gyp, exposing kotlin / swift libraries via C ABI w/ a JS API. Miso accesses the kotlin / swift native modules by FFI'ing into the JS that exposes them.
The JS doesn't get compiled, but on Android it does get JIT'd. So it's "native" in the sense that the views drawn are native (not WebViews), and the device APIs are native, but not "native" in the sense that it's compiled.
That is very interesting. I never knew that JS could access native APIs. That's very promising for compilers that can generate JS, like GHC!
Working on a phone app that streamlines household management for unmotivated losers (like me) so that they stop wasting money (wasted food) and time (procrastination)
Working on an app that helps me (and other people) do household management on autopilot. It helps me manage things, food, expiration dates, shopping, chores, and I get notified periodically to review my lists. I waste way less food and I actually do my chores instead of procrastinating. https://okthings.app
It looks like you have to do a lot of data entry when you buy things, no?
Yes. How i tried to solve it: you have a shopping list where you can add things on the fly. These things will need to be categorized (food, household supplies etc) at a later date, which is when the review is due for the "Uncategorized" category.
Generally, i tend to buy the same things, so the "big" data entry job happens only once.
Learning that RCS is even more of a monstrosity and a lie than I thought a few years ago. Yikes. Lots of groundwork a decade ago setting the stage for "the carrier creates a common service anyone can interact with" (like sms/mms currently do, which would be great) but in practice it's pretty much 100% "only the carrier app or Google/Samsung messages has access to literally any of it".
Yeah I'm not gonna touch it and I'm going to actively encourage people to disable it. Use signal instead.
Working on a low cost, miniature Bluetooth tracker. The inspiration was my parents keep losing (forget) their spectacles in the house. I wanted to build something that is very easy and simple to use and it was important to keep it small. SO the form factor is something like an airtag but 10x smaller which can be just stuck on to the spectacles and forget that it exists. Next step, obviously is to build a simple app that shows the location of this tracker with a range based on the Bluetooth signal strength.

Made some updates to this open-source library I wrote to render audio waveforms using the GPU on the browser (WebGPU).
Example on the site. Works without enabling flags on Chromium browsers. There's an example to scrub and zoom in real time on some audio. Feedback welcome!
For fun have been creating a mashup of old school DnD map generation using Commodore "10 Print Chr$(205.5+Rnd(1)); : Goto 10" style logic (in TS/Svelte/SVG):
Have been down a rabbit hole ensuring the stairs are realistic and that grid connects properly. Lots of fun and frustration with AI coding tools trying to solve that (they mostly don't/can't). Some fun detours learning a little Prolog to help out as well.
I'm building a coding agent, named VT Code [0]. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter. Supports multiple LLM providers with automatic failover and efficient context management. Support OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, OpenRouter, Z.AI, Moonshot AI, MiniMax, and Ollama (local & Cloud). Agent Client Protocol and Model Context Protocol fully support. VT Code supports a rich set of configuration options, with preferences stored in vtcode.toml. Has both Visual Studio Code and Open VSX extensions so that you can install in VS Code or Cursor, Windsurf, Eclipse.
I've been building it for several months now and enjoy the learning process, I also wrote a blog post and learnt a ton about terminal, ANSI processing. The learning has been immense for me, I now have working knowledge of ANSI escape codes, grapheme clusters, terminal emulators, Unicode normalization, VT protocols, PTY sessions, and filesystem operations, all the low-level details I would have never think about until I were implementing them.

Highlighting the nftables rules. For Vim/NeoVim editor, using your own color scheme and background.
Like grouping statements together within a rule with heavier emphasis on keywords that starts each of its statement.
Even has the easiest Vim installer, `make install`/`make uninstall`; none of that funky Vundle, or other relatively unknown Vim packagers.
Has over 2,500 semantic nodes, 15,000 syntax match statements, and under 5ms rendering.
This is a purely deterministic LL(1) full semantic parser.
https://github.com/egberts/vim-syntax-nftables
Skip the release (I cannot delete it), go full repo clone.
Is it ready? Yes, almost entirely, unless you are a firewall expert using few remaining nftables-supporting but esoteric features like ‘synproxy’. Gotta master that first before I can highlight it properly.
Finally started getting back into game programming and have been working with Lua and Love2D - been trying my best not to get bogged down in the weeds (eg how do I animate a 3d cube on a 2d plane?) and I’m focusing on learning how to actually work with the Love system and organize my code. I’m getting a crash course in jj as an added bonus!
Building an ai powered threats deception proxy.
It's a honeypot system that uses AI to mess with attackers. When someone tries to hack your app, it detects them and serves up fake responses based on attack type.
The system learns from attackers behavior and creates convincing decoys to waste their time and frustrate their efforts. It's basically a trap that gets smarter the more attackers poke at it.
Tired of having my notes spread everywhere, on uncomfortable software, I'm writing my own Notational Velocity desktop app clone in Godot:
https://share.combo.cc/-Z7hBzNbaCc
(work in progress prototype, design is not final)
Intentionally made simple and centered around plain text files and editing speed. I've spent a week on the prototype, now it's good enough to dog-food. Would like to eventually distribute it as a multi-platform app.
I’m working on a MUD server. I want text-based adventures.
Also... would it be crazy if services and social media were text-based applications too?
Not necessarily through telnet, but with some kind of standard so that instead of the web/browser, we use a CLI(s).
I dunno, maybe I’m just bored.
Recently I've been wanting to build a chat server that works over ssh. And by that I don't mean it uses the ssh protocol but that you ssh into the server and the shell you get is the chat client.
One day, maybe
I've been really frustrated with the state of networking and discovering new career opportunities lately. Both in person and online I feel like there aren't very good tools and I have a growing disdain for LinkedIn. I wanted to make a tool that helps ambitious navigate their career goals and meet people who are going to move the needle. It's called Catalyst: https://getcatalyst.tech/
Hey, how can I contact you privately?
I followed up via email
I have been working on https://easymiet.eu/ It is specific to the German rental market. Basically if you want to rent an appartment in Germany most landlords require you to fill out a non-standardized self-disclosure form. That can be annoying to the landlord because especially in larger cities you might have a couple of hundret applicants and it is also annoying to the possible renter since they have to fill out the same information for every apartment they apply for. This is where easymiet comes in. As a landlord you can generate a viewing, shared it through QR or a link. Interested renters can apply using their profile. It also has a application approve and dismissal workflow automatically sending emails to the applicant. My plan was to monitize it selling applicants the ability to add more info to their profile like a picture or relevant documents. However so far I haven't been able to generate much interest. The tech stack is Next JS with BetterAuth, Drizzle and Postgres. It is hosted on a Hetzner VPS using Kamal ( wrote a blogpost about that if you are interested: https://markow.dev/blog/complex-next-js-app-kamal )
Quick feedback: looks way too empty for me to look real. Could also just be a scam. Also: why would I as an applicant add more data for money? The landlord has the benefit, they should pay for that.
> Wir sind nicht bereit oder verpflichtet, an Streitbeilegungsverfahren vor einer Verbraucherschlichtungsstelle teilzunehmen.
Doesn't help haha. Maybe explain why?
To be fair, the thread is called "What are you working on", so it's by definition work-in-progress.
> Also: why would I as an applicant add more data for money? The landlord has the benefit, they should pay for that.
In many hot rental markets (My experience mostly with Berlin), you are mostly not in a position to say "the landlord should pay that" and everyone is desperate to supply the best, most complete and most convincing documents even if it feels bad to fork over that much personal data to a random stranger on a platform.
Bread and butter stuff. Pulling together all of the assorted algorithms and data structures I implemented in C over the years out of necessity - lists, trees, stacks, queues, hash tables, memory pools, etc. - aligning the APIs, cleaning up and merging into a library. It's a background project but super fun. This and several parsers - JSON, some config file formats, and parsers for some GPS / GNSS receiver data protocols. FSMs also always feel like nice, clean fun. And prematurely optimising every bit.
I’m building Sink It for Reddit (https://gosinkit.com), a browser extension to make Reddit usable on the web. It’s similar to RES with broader support for all the different Reddit UIs (there are 4).
It’s mostly free with only old Reddit features gated behind a one time $5 fee. The app has a few hundred thousand users on the Apple platforms but recently it was invited to join Mozilla’s Recommended Extensions program so I’m hoping to grow the non-Apple user base.
Creativity and game development clubs for kids:
https://breaka.club/blog/why-were-building-clubs-for-kids
Basically, I'm building tooling and providing these to community run clubs that help turn kids from consumers into creators. I'm focusing on game development initially, but have plans to expand into other areas of creativity.
We're using Godot + GodotJS (which I'm a maintainer of): https://breaka.club/blog/godots-most-powerful-scripting-lang...
I've much experience building software for creators. I'm a (core) developer of Tabletop Simulator. I worked at a now defunct startup which allowed people to create and distribute their own interactive fiction stories using partner third-party IPs.
I have a background in EdTech. I used to be Head of Engineering at Ender, where we ran custom Minecraft servers for kids: https://joinender.com/ and prior to that I was Head of Engineering at Prequel / Beta Camp, where we ran courses that helped teenagers learn about entrepreneurship: https://www.beta.camp/. During peak COVID I also ran a social emotion development book subscription service with my wife, a primary school teacher.
Sewing my own clothing.
But of course the programmer in me needs to make my own software to design patterns with code. Enjoying using paper.js to do all the complicated math to calculate lengths and angles.
Month three working on my game development resources website: https://raizensoft.com/tutorials/
I write almost daily article about libGDX - my most favorite code-centric game framework. There are now over 100 articles covering topics from basics to advances. I plan to post more because this is more or less a passionate project.
In the future I hope it evolves into a definitive resource for learning game development with Java and libGDX.
A tool for “grep”ing MIPS binaries[0] to find duplicate code (functions, segments, sections) primarily to aid in decompiling.
It does some neat things to match instructions while avoiding location dependent references, then creates a hash that can be used to used to search binaries in linear (or faster!) time.
Still a WIP, but being used on at least one decomp project.
Ugh. It's time for me to start transitioning my iOS/Watch/Mac programs to be "Liquid Glass-native."
I should be able to do it with my various personal apps, but one app I've written, was done in concert with a professional graphic designer, and he is not happy with LG, so I expect that app to be a pain.
These are my apps: https://littlegreenviper.com/AppDocs/
I'm working on https://www.evcourse.com/ (I work in the EV industry)
This is pretty cool. can imagine it being useful for people thinking to switch to am EV.

We are building end-to-end accessibility compliance tool[1] that will take care of auditing, remediation, verification and generation of ACR/VPAT.
Because of the well bound nature of the problem space, we are able to unlock a lot of power from LLMs and put together a good end-to-end product that delivers the promise.
Still early days. I know there are lot of folks who care about a11y. I would love to chat and learn from your experience.

I am finally making my own blog. I have been only planning for ages. I found that I had a lot to say for the past years working on AI, and I want to record them somewhere. I do not expect a lot of visitors or at all in fact. The blog is going to be just for me to remember stuffs and to keep track of them.
I am using hugo to build suckless static pages. LLM helped me so that I don't need to read all their docs. I haven't finished it yet nor posted a single blog. But there will be one soon.
I’ve been reverse-engineering an obscure childhood game called Entomorph:
https://github.com/entomorph/reverse-engineering
I started the project when ChatGPT 4 was first released, using it as a way to explore what LLMs could actually do. I also find working on it very relaxing, there is something cool about uncovering secrets hidden in code for more than twenty years.
I'm thinking a lot about the ARC-AGI ML benchmarks, especially the "shape" of the dataset and what that says about how it should be solved. I think there's good reasons to believe that deep learning - at least differentiable SGD backprop style - is a bad fit for this specific benchmark, due to the tasks being almost entirely discrete symmetries, and also having so little data to approximate the discrete symmetries with continuous ones (considering deep learning to be the learning of continuous symmetries). I think that a more explicit and discrete approach is the way to go, and it's possible to build something surprisingly general and not heuristic-based even without gradient descent, guided by minimum description length to search for both grid representations and solver functions. I'm looking for teammates for ARC-3 so hit me up if this sounds interesting, I'd love to chat!
I made a viewer on my website to build intuition for my preferred perception algorithm which is entropy filtering + correlation. Pretty neat to check out the heatmaps for random tasks, there is a lot of information inherent in the heatmap about the structure of the task: https://synapsomorphy.com/arc/
I’m working on a performance capture library for Python because I often need to know the performance of backend systems I maintain. I frequently build tooling to capture performance and save it for later analysis. I/O operations get costly when writing lots of data to disk and creating good real-time analytics tools takes a lot of my time. I wanted a library that captures real-time performance analytics from Python backends.
https://github.com/jakeroggenbuck/kronicler
This is why I wrote kronicler to record performance metrics while being fast and simple to implement. I built my own columnar database in Rust to capture and analyze these logs.
To capture logs, `import kronicler` and add `@kronicler.capture` as a decorator to functions in Python. It will then start saving performance metrics to the custom database on disk. You can also use the middleware for FastAPI.
You can then view these performance metrics by adding a route to your server called `/logs` where you return `DB.logs()`. You can paste your hosted URL into the settings of usekronicler.com (the online dashboard) and view your data with a couple charts. View the readme or the website for more details for how to do this.
I'm still working on features like concurrency and other overall improvements. I've added a lot since the last time I shared on HN. I would love some feedback to help shape this product into something useful for you all.
Thanks! - Jake
I wanted to see if I could use generative AI to build a whole business. Not just a digital product or an app — but the entire business from end to end:
(Spoiler: I did manage it and launched in just 75 days from start to first order)
- Three tier corporate structure with manager-managed LLCs and a private WY LLC as manager, complete with a knowledgebase-powered assistant that can write share registries, banking resolutions, meeting minutes, contribution contracts, loans and more
- Supply chain management with proprietary lot tracking that tracks PO line items from production to delivery
- Generated the base for all product images, helped write and research label design and text, wrote SEO titles and product descriptions
- Used Claude Code to build the entire Shopify theme for the site, all collections, product pages, legal pages and a COA database to boot
- Used Claude Code to build a custom Shopify app to integrate lot tracking into the shop so that when lots sell out the next lot is queued for sale and all lot-related metadata is synced to the product variant and displayed on the product page
- used Claude Code to build a super analytics platform that combines the data from GA4, Shopify orders, and Meta business suite into a single feature store where I can wrangle the data to ask/answer any question I can dream of about audience segments, product popularity, what’s working or not, and get insights on what to do next

Currently building a suite of media inspection and encoding tools for video engineers: https://video-commander.com.
Still very much a work in progress, but expecting to release a first version by end of year. Built on Tauri, in case anyone is curious.
I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium.
I'm working on Habitat. It's a free and open source, self-hosted platform for communities to discover and discuss their local area. The plan is for it to be federated. I've recently solved an issue with cron jobs that was driving me mad for ages. I feel that I'm pretty much nearing a first tagged release, but I feel that I need to work on branding and messaging a bit before I do. I can't tell if I'm procrastinating that final push to something that makes it more official or not.

I'm building a Twitch streamer focused version of cameo. The first beta version is specifically for League of Legend streamers.
https://demo.replays.lol/clipper (recording the demo video today).
The idea is that a generic video message doesn't appeal to a fan of a video game streamer, instead what really would be cool would be watching them react to your best moment in a game.
Our software removes all friction from the journey, the fan doesn't even need to record their own gameplay, we have bots set up that can load up someone else's gameplay just from their username, record their highlight for them, upload it to our platform, then the streamer just needs to come in, watch a ~60 sec clip, give a genuine reaction, press 'submit' and its all done.
There's a few markets I'm trying to find product market fit in: ~1-2 minute coaching sessions, sports commentator style commentary over your clip from influencers, hyped up reactions from your favorite streamer, a community-focused segment on a stream of watching a compilation of your fan's best moments.
We're ready to launch, just trying and struggling to find the first few people to sign up.
I'm currently in a group project for my edtech entrepreneurship course where we've launched a start-up website off of lovable, which provides an ai chatbot that helps check CVs and run mock interviews for finance and consulting students looking for internships: https://next-step-craft.lovable.app . Test it out now!

I’m working on a platform to run a friendly competition in “who builds the best reasoning AI Agent”.
Each participating team (got 300 signups so far) will get a set of text tasks and a set of simulated APIs to solve them.
For instance the task (a typical chatbot task) could say something like: “Schedule 30m knowledge exchange next week between the most experienced Python expert in the company and 3-5 people that are most interested in learning it “
AI agent will have to solve through this by using a set of simulated APIs and playing a bit of calendar Tetris (in this case - Calendar API, Email API, SkillWill API).
Since API instances are simulated and isolated (per team per task), it becomes fairly easy to automatically check correctness of each solution and rank different agents in a global leaderboard.
Code of agents stays external, but participants fill and submit brief questionnaires about their architectures.
By benchmarking different agentic implementations on the same tasks - we get to see patterns in performance, accuracy and costs of various architectures.
Codebase of the platform is written mostly in golang (to support thousands of concurrent simulations). I’m using coding agents (Claude Code and Codex) for exploration and easy coding tasks, but the core has still to be handcrafted.
Ooooh, neat, I had a similar idea, like an AI olympics that could be live streamed where they have to do several multi-stepped tasks
Yep, exactly the same concept. Except not live-streaming, but giving out a lot of multi-step tasks that require reasoning and adaptation.
Here is a screenshot of a test task: https://www.linkedin.com/posts/abdullin_ddd-ai-sgr-here-is-h...
Although… since I record all interactions, could replay all them as if they were streamed.
Currently working on building my first 3D printed star tracking rig for astrophotography (via the incredible OpenAstroTracker project) and beginning to think through a 3D printed Dobsonian telescope. Also working on some ceramic glazing techniques to try and make cool gas giant-looking tiles. I'm on a real space kick right now!
A structural biology viewer/editor/CAD-style application. Combines functionality similar to PyMol, Coot, VMD, and GROMACs. Open-source, standalone executable. Built in Rust and CUDA.
And the host of bio libs required to do it. The sort of thing that are mature in Python, for example, but I needed to build for Rust.
I’m currently creating a simple community where people can honestly share their emotions and empathize with others’ feelings (without comments). It’s a web community where users can receive a comforting message from AI based on emotion analysis of their text, emojis, and chosen colors.

I would love feedback on the post, how do you see the tech stack for software control evolving into this new category.
I've spent several years since Covid times solo-developing an ad-free website with 50+ solitaire/puzzle games.
I've gathered some feedback from users from HN already and now trying to fix things.
I'm looking to genuinely improve the experience so would be incredibly grateful for any feedback. I'm also wondering what it lacks – any particular games or modes?
A game-agnostic social/legal/financial overlay for virtual worlds. Minecraft, Rust, Roblox, etc.: legal ownership claims (vs possession), titles (recognized by other players or not), laws, player-issued currencies. Smart contracts but with as little blockchain stuff as possible.
The iron rule is no direct interaction with the world. These are things that players can in theory always start on their own as long as they can communicate.
Local only meeting transcription and summarisation for MacOS.
Loads of similar products out there, but non that did all of: open source code with attested releases, recorded mic and system audio to work with any meeting app and used Apple Intelligence for private summarisation. In beta, and also just released a experimental version with self hosted Ollama support.
Working on a little project to make Spotify recommendations better.
You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get.
Does this deal with, what I call the "Armin Problem?" I typically listen to EDM and there is an extremely popular DJ named Armin van Buuren, and he has other aliases (which exacerbates the issue). His sets end up directly on music platforms, and he pulls in a ton of EDM sub-genres (which makes him a great DJ!). Any recommendation algorithm that visits one of his aliases is doomed to be connected to every other sub-genre, so I might be listening to progressive trance, and be in the mood for that, and end up on deep house (as an extreme example). Within EDM, genres can be as different as blues is to metal.
Not directly, no. I still rely on the data that Spotify gives me that relates to artists' information; and it's not great a lot of the time. E.g. there are obvious cases where artists belong to genres that they should not belong to. I do have some ideas for improvement, but they are still WIP.
What it allows you to do, though, is create your playlists with extended filters. E.g. you can select genres, and at the same time exclude genres - that helps with the "cross-contamination". You also get a view of all the artists that match your selections and you can add exclusions for them as well. It is a bit of manual work, but it works pretty good for me personally.
I've been writing https://urbanismnow.com weekly for a year. The idea is to bring you the best ideas from around the world to inspire action where you (c)are.
It's been going well for a side project and now I'm thinking of expanding to have a directory of urbanists on a map so you can easily find people involved in the local discourse and how to get involved.

I'm working on an TTRPG Toolset for managing universes
It's still early in development, but it has a large number of features that I've always wanted. A dynamic entity system so users can create their own entities with their own traits. Random tables. A madlibs still generator. All of these things work together, too. You can have tables that randomly pick other tables values, or you can reference your own custom entities. And all this can be tied to maps or a calendar. Again, all something users can create. And of course, all of this can be shared out so you can have a published gazetteer and encyclopedia of your world that is easy to manage.
Mostly done because existing systems were too clunky, and wikis don't offer the same level of control and reuse. For example, you can reference entities parameters in other entities allowing you to embed data in multiple places and have it have a single source of truth.

We've been tinkering with building realtime talking head models (avatar models, etc.) for a while now, and finally have something that works (well enough)! Operates at ~2x realtime on a 4090, significantly faster than that on enterprise grade GPUs.
You can try it yourself at https://playground.keyframelabs.com/playground/persona-1 and there's a (semi)technical blog post at https://www.keyframelabs.com/blog/persona-1
The main use case we designed for was language learning, particularly having a conversational partner -- generally we've found that adding a face to the voice really helps trigger the fight or flight response, which we've found to be the hardest part of speaking a new language with confidence.
But in building out the system around the model to enable that use case (tool use on a canvas for speaking prompts and images, memory to make conversations less stale, etc.), we think there's potential for other use cases too.
Building Valori, a Python-native vector database. It’s basically Lego blocks for embeddings: storage, indexing, quantization — all modular, all hackable. The goal? Let anyone plug in their own models and search pipelines without touching C++.
How big of a threat is AI to your career? Upload your CV and it will be analyzed. You'll also get steps on how to reduce this risk.
Still working on this and some things will definitely change, but IMO the system prompt is already solid, so that the response isn't unnecessarily scary on one hand, but not too general on the other
Tried it, but it says it can't extract text from PDF resume.
Unfrotunatelly, it happens and I am aware of this. In that case:
a) you are lucky because your CV is not scannable by AI so it's good if you want to keepyoru carieer as far as possible from AI tools ;)
b) you are unlucky: most likely the software recruiters are using to pre-screen applications (and they are using it a lot) is not seeing your CV either so you will be dropped on the first stage, :( work on this if you consider finding new job nowadays
c) if you still want to use my tool consider extracting CV's text to .txt or reformat PDF (this will help you with point b)
I am confused. What makes it not scannable? It's just a Word doc exported to PDF.
Please try this https://www.freeconvert.com/pdf-to-txt It uses the same library I use.
You will probably see only some footer/header content from your pdf.
In general, word doc has some caveats when it generates pdf. Not everything is retrieval when you try to get the pure text content.
Nope. It got the whole thing. Might be an issue with your app.
A database populated with audio metadata (including a link back to YouTube or Spotify or whatever) that includes vector embeddings for the audio. That way I can grab clips of music I like from YouTube, generate vectors for them, then find similar things in the database.
It's off to a rocky start though, as I've initially populated it with YouTube-8M and AudioSet, neither of which are music-specific. The search results can be... Weird.
New (open source) PostgreSQL index type for analytics workloads, which is a read-only drop-in replacement for B-trees. Smol is multiplicatively faster than B-Trees and radically smaller.
Help, alpha testers, etc all welcome. Sorry RDS/Aurora users: smol is for embedded and self-hosted pg instances only for the foreseeable future.
Currently working on training language models steered towards certain "states of consciousness".
I have a model trained on publics datasets tied to brainwaves and/eye tracking and text comprehension (have this working well enough to experiment). Now I am training an adapter for various llm architectures to generate text steered to certain neural oscillation patterns (let's call them "states of consciousness" for brevity). I also have a 'rephraser' that rephrases text to elicit these certain states of consciousness. Overall experimenting with creating an suite of tools off my findings with how text relates to the eigenmodes of consciousness. My theory is once I do this I'll be able to do some...interesting things with "AI" agents. lmk if you want to talk about it if you're someone with knowledge in neuroscience/ML. My background is as a Software/ML Engineer so I could use additional thoughts. I do wish I could send a Github/docs which I will soon but this is currently a private project seeking investment for various research/public/private sector applications.
Unwound a couple of things from the stack!
Finished: the 100%-vibe-coded "GPT-5 reviews all my PRs on max reasoning" GitHub app (which is shockingly effective, https://github.com/Smaug123/robocop - probably nothing new for people who already use some product like this, but I like owning my own infrastructure as far as possible, and GPT-5 and perhaps Gemini are the only models smart enough to do this so I can't take this any further).
Currently: back on "write an immediate-mode TUI framework that uses a vdom as its fundamental abstraction" (https://github.com/Smaug123/WoofWare.Zoomies), in the hope that this is the first UI framework that I don't absolutely loathe.
Next: using the TUI framework, write a debugger to inspect the internal state of my deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint) and to step forward and backward in time.
Next: get the deterministic .NET runtime to a point where a property-based testing framework can identify the deadlock in some very simple buggy multithreaded code. (The framework is not yet able to run Hello World - did you know that's an incredibly complicated program in .NET? - but it can solve a few Advent of Code problems right now, can perform some limited exception handling, limited virtual method dispatch, limited casting between types. Even getting to Hello World might take a year if I'm unlucky.)

A gamified bird sound ID app. Been working on it since May of 2024. While the core functionality of “catching” birds has been live for awhile, I’ve been working on a learning module built into the app. I’m experimenting with ways to teach new birders / nature curious people how to “tune” into different bird sounds. As a birder one of my favorite things to hone has been trying to differentiate songs and calls in the field and I want to capture that experience in the app.

Love any and all feedback!
This is sick! I'm not a big birder but maybe this is the push I need to get into it lol. App seems super polished. Well done.
hosting a month-long residency for indie hackers in Da Nang, Vietnam!
we invited 10 of the best indie devs from around the world to live & build alongside us for a month at a beautiful villa. for free. (we have sponsors like OpenRouter, Cognition, n8n, and CodeRabbit!)
we're 10 days into our first batch – would love feedback :)
I'm working on https://yap.town - an SRS based language learning app.
I would say it combines the best parts of Duolingo and Anki. Anki is great for memorizing words, but you don't see the words in the context of novel sentences. Duolingo is great for exposure to new sentences, but it's oriented around "lessons" and SRS is an afterthought. (Duolingo is also not designed for people serious about learning a language IMO, it's too easy and goes too slowly.)
Had to do quite a bit to get it to work well.
1. At first you would think that if you know all the words in a sentence, that should be enough to understand the sentence. But it doesn't work like that. For starters, words can have multiple meanings. The french word "bois" can mean "(you) drink" or "wood". You want to learn these separately. I trained an NLP model (a gemma3 finetune) that I use to understand the manner each word is used in each sentence: https://huggingface.co/collections/anchpop/lexide-nlp-models
2. Even then, what about a sentence like "you'd better not"? Even if you know the words "you" "had" "better" and "not", you still won't really get this. So I use the wiktionary "multiword terms" category for each language to get a huge list of terms like "'d better" , "you better believe it", etc, and teach these in addition to individual words. And then I only show sentences where you know all the individual words as well as all the terms.
Love that the "town" in yap.town in the title swaps to the language you're learning.
Few pieces of feedback:
* I would expect light/dark mode to follow system by default
* I'm not sure why I need to keep clicking "learn one more new card" after nearly every card I learn
* AI grading is actually done quite well, but is a little slow for the normal "flow" I'm used to when doing cards in Anki.
Think this is great overall though, feels actually unique in a crowded space. Best of luck!
This is awesome sir, I'm pretty sure this will get you very rich soon or later.
By the way, I have a suggestion, the examples on the answers could be listenable to keep the brain on a learning mode all the time even on side words
Great idea, done!
And I'm not planning to get rich off of it haha. Right now there's no monetization at all. If lots of people use it to learn a language and avoid wasting their time on duolingo, I'll be happy
I am building https://arabicworksheet.com, AI powered Saudi Arabic learning app for expats who work and live in saudi arabia. 100% FREE. It generates printable worksheets based on your level, dialect and topics.
I am also building an app for kids to make their arabic learning fun, rewarding and enjoyable. Do try and share your feedback. TIA
I'm working on a performance review (PR) management platform that doesn't require a steep cost and deep integration into HRMS platforms.
It's a need I have for myself and the teams I run – It offers direct PR's, 360º reviews, recording of wins and lessons (something often overlooked), and aims to be a platform for team and individualised growth, that is accessible to small and large businesses alike.
I'm working on Chatolia, an AI chatbot builder.
The goal is to let anyone create task‑specific agents, train with their own data and an embed it into any site.
Training is simple: paste text, upload files (PDF, DOCX, Markdown, CSV), or paste URLs and it will crawl/index them into a per‑agent knowledge base.
I'd love to know what you think.
I’m starting a book club!

How?
I'm a prolific reader but outside of short fiction I can manage maybe 4 a month.
I genuinely want to benchmark myself with fellow peers how on long they take to consume text book. I am not that into fiction or short fiction books - I generally loose interest.
How long would technical books take you to complete, say you have to read Effective Java 3rd Edition
I haven't read a technical book in a long time. I read "You Don't know JS," which is very very short, in about a week. I read "Cracking the Coding Interview" in 3 weeks.
As for non fiction, I read "Anarchist Communism" (fairly short) in a week, "Delivered from Distraction" in a month, "Masters of Doom" in about 2 weeks.
It depends on my interest more than anything. I obliterated the entire Robin Hobb "Assassin's" series, 12 books, in just about two months.
Pretty easily doable by reading multiple books at the same time! Averages out to ~50 pages a day.
The trick is to always keep the book queue filled, so long books that take a while coexist for a while with a number of shorter length ones
https://tailgator.app, playing around with serverless Tailscale nodes
https://coolinary.app, simplifying cooking and recipe ideas
https://capi.tax, preparing capital gains tax reports from foreign brokers for German income tax (still closed)
I like these product names :) keen to give tailgator a try
I wanted to visualize all my walks and runs on a single map. I built a native iOS app that fetches Apple Health and Strava workouts and visualizes them. Privacy was a major factor in building the app, so all the data stays on the device. Next version will have a time-lapse video option. Any feedback welcome.
Very cool, downloaded and using it right now. Do you have any future plans with this?
I'm working on a feature to create fun timelapse videos of all the routes on the map. It should be released next week.
I'm open to any feedback.
Strava and Apple Health integration is cool! What was your main differentiator to build it vs something like https://fogofworld.app?
Thanks. I wanted to focus on performance (native app), simplicity, and privacy.
Spent the last three months building a competitor/lookalike ML model + API. Started using plain embedding similarity and quickly realized you end up with similar noisy results as ocean.io. Ended up using similarity learning which works quite well with little data. Launched this as an API and small web app. Hardest part right now is to fend off scrapers honestly.

I'm trying to learn 3D scanning and printing: I have a few small projects that I want to do to develop the skill:
I want to 3D print a shell that goes over my car fob: I keep leaning on it and setting off the alarm. The shell would make sure the buttons never get pushed.
I want to 3D print a sleeve that keeps the NCAS dongle in my car charger. I really wish there was a dongle that stayed attached with screws or similar.
This sounds interesting and practical. Where can we follow your project?
My website is in my profile. I'll try to remember to write a blog entry in a few months. (Fair warning, I redo my website every 5-10 years to keep up to date with web technologies.)
FWIW: I was playing with an inexpensive (for me) Revo Inspire over the weekend. It feels somewhere between learning an instrument and taking a daguerreotype. There's a lot of room for improvement in the equipment for someone like me who just wants to casually scan something so I can make an attachment part. (I kind of wish there was a box that I could clamp something in, and then have it be about as easy as a flatbed scanner.)
I ended up covering my key fob with blue painter's tape, which kinda-sorta got it to scan. (I tried dry shampoo and drawing on it with marker, but I could never get a big enough area to scan.) When I imported the scanned fob into Tinkercad, it really distorted.
I ended up ordering a set of digital calipers and I'm going to try skipping the 3D scan part and go directly to CAD.
Been working on my programming language https://github.com/buzz-language/buzz for 4 years now (with some down periods). Currently mainly working on the tooling: LSP, DAP and formatter. Also managed to get fuzzing working with AFL++ and found a bunch of bugs with it.
I'm working on _prompt injection_, the problem where LLMs can't reliably distinguish between the user's instructions and untrusted content like web search results.
Just published a blog post a few minutes ago: https://alexcbecker.net/blog/prompt-injection-benchmark.html
Good post. Thanks for sharing. I enjoyed it as much as I enjoyed your anime list. I agree on many.
I'm working on ReFocused (https://refocused.app), an all-in-one productivity app.
It's a personal project that grew out of my own frustration. I was annoyed of paying for (and switching between) 8+ different apps for my Pomodoro timer, a secure journal, and habit tracking. I wanted to consolidate everything into one clean, fast interface.
I've spent the last few months building it out it's a full-stack app with a Next.js 15 frontend and a FastAPI/PostgreSQL backend. I'm really proud of the tech and the "minimalist UI, maximalist features" feel.
The app is live and free to use. I'd love any feedback on the app itself, but I'm also genuinely looking for advice: What's the best way to find your first 100 users for a new productivity app?
I figure having real users is a good resume boost and its an app anyone can use so I thought getting users would be easy but I've been struggling with it
Stopping Agents [1] - LLM agents that stop conversations early and save time.
Because they're trained using imitation learning instead of RL, they're scalable and easy to deploy with your own data (also open-source!).
Mainly targeted at and tested on quickly disqualifying prospects in sales calls, but can be applied more broadly.

Working on https://greatreads.dev/
A place to find great blog articles by regular folks related to dev/tech world.
Wondering about the best way I can add a weekly newsletter built on top of the content currently being ingested and still looking for more sources to add to the database (let me know if you have any good recommendations).
I am working on something similar but with a different view. I like to get random essay to read whenever I am bored or in-between tasks. So I developed this: https://read2reflect.com/
I have added only about 35 essays for now. Might pick up some from your list too.
That's pretty cool. I also have a "random article" button at the top right, which is very fun to use. I've discovered a lot of great content by clicking on that button.
I'm working on basi, an alternative/syntax to writing Playwright: https://github.com/zikani03/basi
Trying to keep it simple but I can already feel some "design pressure" to think about making the DSL more complete (language) by adding features like loops and variables. Still early days!
An AI-powered social media management tool that creates, schedules, and publishes content automatically across Twitter/X, LinkedIn, Facebook, Instagram, and Threads.
*The problem:* As a solo founder, I was spending hours each week on social media - writing posts, scheduling them, managing multiple accounts. I wanted something that could handle the entire workflow automatically while still letting me stay in control.
*What PostSam does:* - AI generates content tailored to your brand voice (you provide initial brand info) - Creates full content campaigns with posting schedules - Calendar interface to review, edit, or reschedule posts before they go live - Auto-publishes to all connected accounts - Learns from your edits to improve future content
*Current status:* Live and working. Seeing good engagement rates from users who set it up once and let it run. The AI content quality has been surprisingly good - it adapts well to different brand voices.
>Twitter/X, LinkedIn, Facebook, Instagram, and Threads
All those have official API for creating posts? If not, there is a chance they will ban the tool.
Tools to help my mental health tracking[0], and sharing with others how I manage my limited amount of energy[1]. They're kind of related, since mental health impacts my energy, so I've needed to prioritize and really make sure I'm spending my time and energy on things that matter. Usually, there's a good mix of things I enjoy doing with things I gain a lot out of. I've spent a lot of time thinking about this!
I've used my app in various forms for around 5 years, rewritten multiple times. But now I'm creating surrounding tooling to help others put my mental model for personal life prioritize to use. I'm writing in the "Saving Spoons" Substack as I go, trying to explain why and how I do things, with advice for others trying to do the same thing.
I continue to work on My Financé, my personal finance tool.
I’ve been struggling to find substantive traction, so I’m trying to niche down to make the tool really helpful for people who want to quit their jobs.
I built a rudimentary planning and forecasting engine, and am trying to run paid ads to see if the signals resonate with people. I don’t love ads, but maybe trying to understand them will further inform my opinion on them.
One thing I would love to come up with is a way to make the app fully local first, while continuing the ability to sync accounts via plaid. It would be great to not be able to see people’s data at all. Im trying to figure out if there is a good user experience I could provide while minimizing the amount of data I actually have access too. Maybe this feature won’t matter to my primary customers though, I’m not really sure.
I still have a ton of fun working on it, and if it never really makes any money I consider it a great success for my personal learning.
Link for the curious:
I’m working on Reflect [0], it’s a privacy-focused app for self-tracking and self-discovery. You can track metrics, run self-experiments, set goals, view correlations, visualize your data, etc.

Imo, you really should use a pure white background for the App Store screenshots instead of the current greyish background which looks kind of depressing.
Made a website to host a blog! Right now it's empty except for one post describing the process of setting up the blog. I plan to add more stuff once I finish this semester in college.

I have a bunch of ideas and small projects I would like to write about, so I'm really excited about this.
We developed a novel optimization pipeline for LLMs so large models can run on a standard laptop.
Our first prototype optimized an 80B model to run at full 256k context at 40 tokens/s while only taking up 14gb of RAM.
We are currently leveraging this tech to build https://cortex.build a terminal AI coding assistant.
Historical public companies Merton Probabilities of Default.
A project just for fun and still having to finish a couple of things.
I plan to make the datasets public (everything but some raw market data as vendors don't allow that) and also about to add the explanation of what Merton PD is.
Chipping away at trying to bring a total reform of American English.
https://reformeuropa.net/raea.html
Currently its at like 90% completion but there are some subtleties that probably need to be worked out a bit more. The PDF linked from that page explains all the details (although for reading just peeking at the charts on Page 4, 5, & 7 should get someone to reading it fine enough). Currently both Alice In Wonderland and Dr Jekyll are fully transcribed into the reform if someone wants to jump into seeing it in action. Certainly interested in thoughts and complaints of the system.
Also looking here sometime soon to playing around with an improved SI unit system. So if anyone has any new ideas here too I'd be very interested.
Examples of things to be touched upon would be like: - Make g (not kg) the base mass unit. Making 1 m^3 of water = 1 g - Bring commas to be the universal decimal point separator.
Frontend framework in JavaScript that requires no build step, relies on DOM and SSR and can be used to build both SPA and hybrid apps without VDOM, js templates, hydration or putting HTML (or worse, css) inside JS code. It'll also have a very sophisticated declarative state manager which makes managing state and ui transitions a breeze. It's basically anti-React.
can you share a repo link please?
Sure: https://code.qount25.dev/qite/qite-js No docs yet, but I suggest you go to test/demo for examples. You can actually see them work if you run it with `node test/server.js`.
State manager isn't there yet, but it's coming.
I'm starting a project soon, with the clear idea that:
- I will not consider it feature-complete
- It might be a waste of time if the performance isn't what I imagined
Basically, I have a pain point with pytest being a bit slow. Nim and Rust (and other languages) have ways to transpile Python code into the other language. I know some Rust tools to run the tests, but they have some differences from pytest.
My idea is to have a runner that transpiles the code to either Nim or Rust, compiles it, and runs the compiled tests. Test discovery for sure would improve, but I have no idea at all if the compile + run time would be smaller than just running pytest normally. There are a lot of challenges in this project, so I'll probably use it to learn another language and some new skills, instead of building something aiming to be usable out there.
Curated LinkedIn topics + AI drafting: validating before building
I'm exploring building a weekly curation service for professionals who want to write on LinkedIn but struggle with "what's worth writing about."
The thesis: In the AI era, execution (writing) is commoditized. The real bottleneck is editorial judgment... knowing what topics matter before they're obvious.
The concept: Weekly email with 5-7 curated topics (tech trends, policy shifts, market movements). Each topic comes with sources, multiple angles, and context Choose your perspective, AI drafts a polished article
Why I think this could work: I've been manually doing this for myself for years. Pattern recognition at scale is hard to automate, but pairing human curation with AI execution might work.
Target market: ~30M professionals who should be building thought leadership but don't have time to spend on research.
Current status: Validating demand before building. The hard part isn't the AI, it's systematizing the trend-spotting and curation process without losing signal quality.
Curing broken developer heads. Good software engineers are good, because they are non neurotypical with many downsides such bad emotion/feeling management with huge avoidance.
My point to help to build your own MentalOS that works for, to live smoother lives without huge up and downs.
Does this follow some structured therapy approach like cognitive behaviour therapy (CBT)?
Exactly. Helps to figure out missing instruction to our body no one gave to us.
I have been working on Buckaroo - my table display library for dataframes in notebook environments. Buckaroo adds table and analytics features like histograms, summary stats, sorting, and search to every dataframe. Recently I have been working to make it work better with large datasets.
This involves making it lazy for polars, allowing it to read arbitrarily large files no longer requiring loading the entire dataframe into memory. When a large dataframe initially displays, no summary stats will be available. Summary stats are computed in the background in groups of columns. Then results are cached per column. To accomplish this I wrote a polars plugin in rust that computes hashes of columns. Dealing with large data like this is tricky, operations sometimes crash, sometimes take all available memory, and sometimes they just run for a very long time. I have also been building an execution framework for Buckaroo. It uses multiprocessing based timeouts, and the caching to execute summary stats in the background.
Being able to control the execution, recover from timeouts, crashes and memory exhaustion opens up some interesting debugging tools. I have written methods that take arbitrary groups of polars expressions and produce a minimal reproduction test case through a git-bisect like process.
All of this assures that if individual columns of a dataframe fits into memory, summary stats will be computed for the entire dataframe in the background. And because it is cached, the next time you open the same dataframe, the stats will be display instantly. When exploring data I do this in an adhoc way manually (splitting up a dataframe by columns and rows), but it is error prone. This should all be automatic.
I will be presenting this at PyData Boston in December.
The Column's the limit: interactive exploration of larger than memory data sets in a notebook with Polars and Buckaroo
What I am working on right now:
-https://salespark.app/apps/discount-spark: A Shopify app that allows merchants to create more powerful discount codes so they can create stronger offers for their customers.
What I recently built but didn't find a successful product market fit:
-https://wordazzle.com: A word game that's designed to expand your vocabulary with exceptional words.
-https://spicychess.com: Chess, meet boxing! Imagine playing chess BUT you can also smack your opponent. Now, if you smack em enough times to drain their health completely(yes, you have a health bar), you can steal their turn. It's fun, a little evil, but after thousands of $ spent on marketing, never found critical mass.
how does the "smacking" work? Is there a VR integration? Is it just button-smashing? It's unclear just from looking at the website w/o signing up
Assuming it’s just regular online chess but you’re forced to share your location in real-time
Haha, it's not THAT spicy ;)
You press a button to smack- there's a 3 clip that shows this on the homepage so I am surprised you find it unclear!
A web app for my music needs - metronome, ABC notation editor with MIDI playback and PDF render, an embedded YouTube video player with a chapter/section creator based on timestamps and a looping feature for the chapters for practicing
https://metro.scopecreeplabs.com
https://metro.scopecreeplabs.com/abc
https://metro.scopecreeplabs.com/video
Offline first, everything is saved to Local Storage. Sharing is also purely serverless - the ABC text and the video chapter defs are shared via query parameters after compression and base64 encoding.
Tech: React, Material UI, ToneJS, ABCJS, CloudFlare (Pages, Workers, D1 Storage)
Next: Add an AI assistant to the ABC editor - editing ABC text gets painful fast.
I've been building a little toy computer and assembly language that's interpreted in python. Pretty close to the first release (and introductory blog post) and a lot of fun to build (and learn a bit more about real assembly as I go).

https://yournextstore.com https://github.com/yournextstore/yournextstore
I'm building Your Next Store (YNS); it's a Shopify alternative built with React and Next.js.
We provide an opinionated boilerplate tailored for tools like Claude or Codex, so designers and developers can build storefronts faster and more easily. It enforces a clear structure to start from while keeping full control over design, animations, and the overall storefront experience. It’s built on top of Stripe, with our higher-level commerce abstractions, like "add to cart", "checkout", "pay", "browse products" etc; plus a Commerce CMS so merchants can manage everything smoothly once their store is live.

SPLADE-easy: https://github.com/dleemiller/splade-easy
I wanted a simple retrieval index to use splade sparse vectors. This just encodes and serializes documents into flatbuffers and appends them into shards. Retrieval is just parallel flat scan, optionally with reranking.
The idea is just a simple, portable index for smaller data sizes. I’m targeting high quality hybrid retrieval, for local search, RAG or deep research scenarios.
SPLADE is a really nice “in-between” for semantic and lexical search. There’s bigger and better indexes out there like Faiss or Anserini, but I just kinda wanted something basic.
I was testing it on 120k docs in a simple cli the other day and it’s still as good as any web search experience (in terms of latency) — so I think it’ll be useful.
We’re still trying to clean up the API and do a thorough once over, so I’m not sure I’d recommend trying it yet. Hopefully soon.
I'm working on SuperCurate (https://getsupercurate.com), which is geared towards note retrieval and curation rather than note creation. Think filing cabinet for your notes, web clippings, images and PDFs.
I wanted fast search and filters for my Evernote archive so I could drill down and surface exactly what I was looking for.
There's also a Web Clipper extension for Chrome.
Demos:

It's free while in beta, would love feedback if you try it.
We recently launched CapitalReach.ai - https://capitalreach.ai We built it to make fundraising easier for founders, it uses AI to help you:
1. Find and match with the right investors automatically 2. Personalize and automate outreach campaigns 3. Track investor responses and manage your fundraising pipeline in one place
The goal isn’t to replace the hustle, just to remove the repetitive parts so founders can focus on building relationships.
Would love honest feedback from fellow founders and investors here:
Does this solve a real pain point for you?
What feels missing or unnecessary?
How do you currently manage investor outreach today?
This month I wrote a small Windows utility to keep a PC "always awake": prevents the PC from going to sleep (using a Windows API that exists just for that) and simulates invisible mouse movements every 60 seconds to keep apps like MS Teams happy, so that the user always appears active.
There is a PowerToy thingy that's similar but it's full of options and command-line flags. My version has no options, it's just a tray utility that can be toggled on (green) or off (orange) with double-click. There are also physical mouse jigglers but they're cumbersome, and many have visible mouse movements, which is extremely annoying (not all of them do this but many do!)
The full install file is just 100Kb, works on all versions of Windows starting with Win7, installs without admin rights. Can't live without it!
I need to make a website for it but I'm procrastinating on that one last step...
ArtCraft [1], a source available Adobe + AI.
Here's a demo / trailer that shows it off:
https://www.youtube.com/watch?v=NNHSTfWbkaA
If you're into movies or filmmaking, it's a fantastic AI tool for consistent, fully-intentional scenes with deliberate set and actor blocking.
It's also the cheapest model aggregator service out there. You can log into every AI image and video provider directly and don't have to pay me anything to use the tool. You can use your Sora account, Midjourney account, Grok account, etc. It'll soon let you log into other aggregators like OpenArt, plug in your FAL API key, etc. so you can use your credits/funds wherever they happen to live.
Unlike the other "model aggregator" websites like Higgsfield, this is a desktop app written in Rust that you can keep. It also has highly intentional 2D and 3D design surfaces especially built for design.
Text prompting sucks for artists and designers, so I'm trying to put image and video design onto canvases that you can intuitively mold like clay.
Here are some short films made with ArtCraft:

I'm building RecallBricks - persistent memory infrastructure for AI coding tools.
The problem: Every time you switch between Cursor, Claude, ChatGPT, your AI forgets everything. You spend half your time rebuilding context instead of coding.
RecallBricks automatically captures context from your coding sessions and makes it available across all AI tools via semantic search. Works with Cursor, Claude Code, Continue.dev, GitHub Copilot, or any LLM.
Built the entire stack with Claude Code (meta, I know). Gas utility worker who taught myself to code, now shipping production infrastructure. Currently in private beta, launching publicly in a few weeks.
Tech stack: Render API, Supabase (Postgres + pgvector), Python/TypeScript SDKs, VS Code extension, MCP connector.
Would love feedback - especially from folks juggling multiple AI coding assistants.
A client-side web app to help scuba divers set up their dive computer.
Scuba divers use computers to tell them when to make stops during ascent to prevent decompression illness. Many recent computers implement Bühlmann's decompression algorithm with "Gradient Factors".
Gradient Factors are 2 free parameters that control the "safety" margin of the dive. It's not obvious what values to choose, especially for novice divers.
My app explains what they are and shows their impact on the computed dive plan.
I’m working on an AI-assisted reminders app using on device models for iOS.
Things like, “get xyz a birthday gift”, and it finds the contact and sets the reminder for a few weeks before the birthday.
The source data is calendar and contact info, but the nice thing about local models is that no data gets sent to providers, and the app can be cheap
We’re working on an AI-first interview platform for developers: Valuate.dev
The usual approach to coding tasks doesn’t work anymore - companies are looking for AI engineers, yet it’s still unclear how to assess AI proficiency.
Our goal is to design challenges that combine prompting + coding, allowing us to score both how well a candidate prompts and how good the resulting code is. The aim is to bring measurement to AI prompting skills - how well-aligned prompts are and how candidates handle LLM-generated code.
At the same time, we want to keep a strong human balance in the process: hiring is a two-way street, and screening shouldn’t be fully offloaded to AI. We’re human-first.
Several tasks are already live - you can try them here: https://valuate.dev
After creating the feature request for Claude Code hooks[1] a few months back, Cupcake is nearly ready for release.
Cupcake is a governance/policy-enforcement layer for agents. Its innovation is binding OPA/rego to agent runtimes (via hooks).
I do not believe we will every strictly rely on "better" models in the wild without deterministic guarantees or ways for enterprises to factor in their own alignment - system prompts dont cut it.
https://github.com/eqtylab/cupcake
Stay tuned for the formal release here in a couple of weeks.

Clever name, and concept.
I'm working on https://mimicmarketer.com It allows you to define different personas that you can then test marketing on. This allows you to see how different personas will interact with your marketing. Currently, it has a feature that allows you to define basic personas and test them against two types of copy, as well as a tool that grades your email subject lines and bodies against a generic persona, assessing the likelihood of user interaction with the content.
My other project is https://eggexplorer.com This is a site I wish I had when building out my flock of chickens. It allows you to see the different characteristics of chickens and which hatcheries sell each different breed. You can also see which hatcheries sell hatching eggs for each breed as well.
Mimic Marketer is useful. Sharing with my marketing friends
I’m working on a few small AI tools in Cursor right now:
A lightweight infographic generator (Gemini API → structured layout → export to PDF).
An AI marketing content tool that takes a topic and outputs research + themed HTML + a printable PDF.
Cleaning up the docs/structure for Schema Scanner, an open-source tool that scans websites and generates Schema.org markup.
Exploring a simple AI search visibility tracker to see how often a brand shows up in ChatGPT / Perplexity / Gemini responses.
Still early, mostly building to understand what’s useful vs. noise, but the patterns have been interesting.

https://github.com/ezeoleaf/mycorust - A mycelium network simulation after I started to get interested in fungi and mycelium. Learnt a lot of Rust and gain more knowledge of performance and resource usage.
- Zig bindings for AVIF/HEIF
- Local-first app for comparing hardware builds, down to the individual component feature level: specs, benchmarks, even cpu extension support, lanes, how many speakers in X laptop, dolby atmos? screen panel manufacturer(s), etc. Basically, no-nonsense real product comparison for transparent and fast decisions.
I am working on a platform that simplifies access control in an enterprise.
A lot of cybersecurity attacks happen because of stolen credentials. One big example is the supply chain attack, Shai Hulud. In a lot of enterprises, credential sprawl is a huge issue and figuring out who (people, services, ai agents) has access to to what systems is a paramount task.
At https://gearsec.io, we are building a platform where accesses are created via policies. The result is that, the enterprise doesnt deal with credentials anymore. They only need to define policies and nothing more.
I would love to know if you faced this problem and how are you solving them at your workplace!
I'm building https://localhero.ai. Automated i18n translations that run in your CI pipeline.
I have worked as dev in many different constellations of the years, and seen many teams choose between bad options like delay feature launches for manual translations, ship incomplete translations and promise "we'll translate it later," or lately use ChatGPT/LLMs that lose consistency/context and require coordination.
Localhero starts from the premise that translations are part of CI. New strings get translated automatically in GitHub Actions, with glossaries and style guides so it sounds like your product and not generic AI output.
Goal is to help product teams ship localized features without all the coordination/delay.
I am right now building a proactive coach on top of my AI work capture app. Concept is very simple: It takes a screenshot every few minutes and analyzes what you're working on. From there it identifies task blocks, and checks if it should start a chat based on your intentions (eg to tell you to move out of your rabbit hole, take a break, help with a task, ...)
https://donethat.ai Passively processing screenshots is obviously pretty sensitive, it has an option to bring your own (local or remote) LLM, otherwise I process with gemini and never store any data.
It's in beta right now so if you want to try it you have to enable "proactive chat" in settings.
I also made a list of similar tools out there: https://donethat.ai/compare
The domain/name is fun.
The idea is controversial as proved by the resistance to Recall.
Morrissey should be your pet (stop me if you think you've heard this one before)
It should start doing what Instagram is doing and transform your activity into visual feedback that is fun to explore by you or the people that you want to show to, what you did throughout the day.
MCP gateway: https://mintmcp.com
There's an agent monitor which intercepts requests either using a LLM proxy or hooks, that gives you full telemetry into the agents + MCPs used. And a MCP gateway that enables centralized deployment and securing of MCP.
I'm working on a browser extension that lets you save a list of all your open tabs into a markdown document. You can format the output using a templating language and it saves direct to your Obsidian vault if you have one (otherwise gives you a markdown file to download, plus a clipboard copy).

I'm building one project a week for the next 25 weeks for my newsletter. First, I want interesting content for the newsletter. Second, I want to try to grow the newsletter to put out something fun and joyous. The world needs more good fun.
Hi, I like your newsletter concept and I do subscribe to it.
One thing I think may be cool, is put a thumbs up/thumbs down link in the email to track sentiment of the links you share. Some links are really cool, others I am not interested in at all, it may be useful to capture that info.
I would visit a site daily if you expose some of that info publicly (like 49% positive 51% negative for a link), to see how my sentiment matches your wider audience.
That's for subscribing and for the feedback! Good idea. I'll put it down on the todo list.
I’m working on Alaska, a serverless compute platform I built entirely from scratch — no Kubernetes, no existing orchestration layers. It can spin up dozens of containers in parallel in just a few seconds. The platform is designed around a fast feedback loop — you write code locally, test instantly, and run it remotely with minimal friction. There’s a Python SDK that uses decorators to define what runs on the platform, so your local functions become distributed services without extra boilerplate. I also built a custom filesystem using FUSE to handle code, data, and runtime synchronization cleanly across nodes. It started as a personal exploration of distributed systems, but it’s grown into something that feels genuinely exciting! It's created by a developer for developers. Planning to open it up for beta testing soon.
I'm working on rebuilding Playwright from the ground up, but focused on automation and self healing using LLMs.
It's called Stagehand (https://github.com/browserbase/stagehand) and we just released v3, which is a total rewrite.
Interesting.
I rewrote Playwright to run completely in a Chrome Extension without CDP or chrome.devtools for no practical reason at all. I started to do it like Forest Gump started running. It can't get past bot protection so pretty worthless from a browser automation point of view. [0]
What I don't understand is why the need to rewrite Playwright instead of just patching it. Playwright (or Puppeteer) has addressed every edge case that has come -- especially race conditions which are a monster to deal with -- up over the years and by the time you do the same you will have Playwright.
Why is rewriting or rebuilding Playwright from the ground up needed?

Very cool. I make a consulting business out of packaging selenium scripts into windows apps for small businesses, do you have any desire to turn this into a saleable product?
Stagehand is our open source project, but the company behind it is called Browserbase - https://browserbase.com/ where we run headless browser infrastructure as a service. So no interest at this point, Browserbase drives the revenue that funds Stagehand!
What type of stuff do people pay you to do?
It's almost 100% secretarial workflow automation. Someone is currently being paid to click, drag, etc. I collapse that into a single button and charge for the button.
To explain better, there's basically 3 jobs avaliable in this kind of work right now, all of which I've interviewed for and been not selected with varying degrees of frusturation.
(1) build a bunch of automation scripts that we can reliably run as part of our product. This is closest to my day-to-day, you're (mis?)using selenium or playwright to make a known set of "click here, fill that, click there" scripts, and then expose some interface that calls them. At a company usually this will be a fastAPI / microservice, and your set of automation scripts is part of what makes the product possible. In my case, I'm currently working on registering my Tkinter/Pyinstaller app with windows so people can run my .exe and click the "do the script" button. There's also a slightly different approach to the selenium/playwright jam that runs curl requests which mimic the network requests of performing some action. You'll be able to see what I mean by clicking into your browser devtools "network" tab and clicking around the web. Imagine having a library of known API calls, you save a users cookie, and run script to achieve result.
(2) build a browser agent that we can use to run all of our (1) scripts. This is stuff that I iterate on as needed, and in my experience is best done by having a bunch of "helper functions" that spawn/kill/season different selenium webdrivers. It will depend on whether your (1) scripts are dealing with JS-heavy websites, bot detection, or just constantly changing UI's, but the deep rabbit holes here end up in places where you're building your own browser agent on top of webkit/chromium, implementing some kind of captcha solver, or trying to automagically discover what buttons exist by fuzzing the API or DOM.
(3) use a (2) to get us every PDF we need for our upcoming RAG chatbot. This is something I do by executing on (1), and I only bother to note the difference because it's a great example of the kind of actualy end product goal that all of this leads to.
Academically, the problems happening in web automation broadly fall into discovery and reproduceability. Discovery, meaning API fuzzing (how do we get that library of known API calls? / the equivalent buttons in a DOM?); Reproduceability, meaning running-without-errors. (How do we wait for the target's server to be ready to send the next command? How do we avoid getting blocked? How do we detect/recover when the target updates their website?) The most interesting opportunity IMO is inserting an LLM to build a self-healing scraper, and the edges of your tes/prod environments will be defined by your product's tolerance for wrong/nondeterministic behavior. I've got a great blogpost draft about a "railroad model of software development", where an LLM is a hammer nondeterministically pounding in railway ties, and an end product is a deterministic piece of code that can have trains run over it all day long. (effectively, LLM as test-environment devtool thesis, I don't think I'm saying anything that hasn't been said before.)
Practically, the problems that are facing me as an engineer are in packaging these tools for sale/distribution. My current state-of-the-art is to wrap up a .exe with Pyinstaller, build a GUI with Tkinter, and register with Windows so I'm not showing scary "This program is made of evil" messages when people try to run it. From there the plan is to give away free trials and after a month of people clicking their magic buttons they all disable and demand you purchase a license to re-enable (like if winRar was evil, but sorry yall I gotta eat). I'm also trying to sell building these tools as a service but that's very word of mouth, I haven't found a viable web/storefront model for that yet.
IM-Practically, most companies with a browser automation component are struggling with the same HR/Onboarding issues everyone else is. In the past ~2 months I've Interviewed at ~4 serious companies that profit from their browser automation, and every process has been unique: 1) firecrawl.dev; a black mirror hourlong AI-chatbot-zoom-interview, followed by a human call scheduled 3 weeks out, only to then be told that really they want someone fully specialized on breaking captchas, with a vaugely condescending suggestion that I'm "customer facing" and no followup when I lean into that 2) atomic.financial; actual-human-zoom-calls with engineers who I get along with great only to have no idea why I'm getting a rejection email the next week 3) sheer.health; a very contentious first call that demands I name a salary, followed by a trivially easy take-home test, followed by my 3rd round, 1/2 hour call with the CEO being cancelled the morning of because they filled the role. 4) Mozilla; where a principal/staff engr cold DM'd me, to schedule a call with an HR rep that told me they're paying 350k base 420k total and another staff eng who's leaving to start a startup, only to then tell me I'm not senior enough but could maybe come on as a contractor, only to then tell me they're using internal resources for the contractors.
Overall, I think the best opportunity in the space is going to look something like https://ui.vision/, which is an open-source tool!

Wrote and released a daily reader on sobriety and stillness called I Will Not Drink With You Today.
There’s a companion website: https://iwillnotdrinkwithyoutoday.com
I wrote the book in markdown, stuck it in a SQLite DB and wrote a parser to put all the data in static JSON so it loads very fast.
I also created a new personal homepage to update my presence on the web as a published author and experienced leader and technologist: https://davidbyrondrake.com
Book was released less than a month ago—growing it organically like a startup has been fascinating in terms of marketing, sharing, building, and measuring success.
Have been utilizing my acting skills again with readings from the book on my Instagram and TikTok.
Having a really good time with it!
In progress: I’m writing a book about how the brain processes text in general - and news articles in particular.

I recently launched this satellite imagery tool.
I work as a civil engineer in the mining industry and it can be troublesome to download satellite imagery for a particular date and cloud index. Yes, Google Earth Engine and QGIS plugins exist, but they are slow and confusing to jump back into after a period of time. SatelliteMine is simple to use and any images of your area of interest is saved to your account and can be downloaded as a geotiff.
Currently free to use with a cloud storage capped at 512MB per account. Paid plans for greater storage requirements will be provided if the demand is there. Any feedback is welcomed :)
Tritium, the IDE for legal: https://tritium.legal/preview
This week we're building out the UX around formatting and this month we're building a more robust set of integration tests and integrating with a large industry platform.
legal is definitely one the industry that interests me. is this a very front-end focus start up? or is it heavy on the back-end too?
I’m working on a platform that makes it easy for people in West Africa to buy and sell cryptocurrencies (like USDT, USDC, ETH, BNB, POL, AVAX, etc.) directly with mobile money — the most popular payment method in the region.
The goal is to bridge crypptocurrencies and local mobile wallets to make crypto useful in everyday life — not just for trading, but also for online payments.
A few key features:
Mobile money integration (MTN, Moov, Orange, etc.)
Instant buy/sell of USDT, USDC, ETH, and other assets
Crypto payment gateway — businesses can now accept stablecoin payments directly on their websites
I’m currently focused on improving liquidity and expanding to more countries.

building a location-based game that captures Taiwan's absurd convenience stores density[1]. Players stand at any 7-11/FamilyMart/etc, take a photo showing you can see the next store, walk to it, repeat. Chain as many stores together as you can.
It sounds silly but Taiwan really is this convenient - you often can see 2-3 stores from one spot. Here[2] one route where you can actually link 7 convenience stores in a row! Now trying to make maps look a bit nicer with mapbox.

system to test and calibrate an analog traction control system. the system uses a frequency to voltage converter and a bunch of opamps to compare wheel speeds then determines wheel slip or slide and either reduces engine power or braking.
Test system uses ADCs, DACs and a DDS to produce a sine wave that simulates wheel speed.

Resterm - Terminal client for HTTP/GraphQL/gRPC. It includes support for WebSockets, SSE, workflows, profiling, OpenAPI, response diffs and many more.
Developing a fingerprinting method for identifying music masterings! Like Shazam but to tell what version of an album you have.
The idea being able to compare measurements to see what mastering you're really getting - because they are NOT all equal. With the remasters and stealth replacements on streaming, it seems like every other month I wake up one day and my favorite music sounds worse (or is gone...). Now I can measure it and help find what versions I really want to collect!
I may end up trying to make a fingerprint database/tool that sits in between MusicBrainz and Discogs. That way hopefully the community can standardize and quantify some of this info that only lives ad hoc in Steve Hoffman forum threads or partially on sites like https://dr.loudness-war.info

Many projects active.
(1) For one product I am working, I have been working on a custom reporting language for producing high quality PDFs. I used hy.py as a basis to make it LISP-like.
(2) I need to make a Django postgres site that I am running more reliable. Earlier I was experimenting with making static HTML renderings of the pages. That is certainly nice, but it took several hours to reproduce the site. I am currently prototyping making read-only replica of the database in SQLite (the database is only 1 MB) and hosting it on CDN, and then pulling that for the read-only replicas. The database export takes only some seconds.
(3) I vibe coded a iOS app using that same SQLite database that fetches it from the same location. It was surprisingly simple. It seems much simpler than using Flutter or React native.

After 10 years in defense tech, watching missile attacks in Ukraine and the Middle East made it clear how little most people really get about air defense. So I'm building this simulator which drops you into the operator’s seat. You can test out different scenarios and build an air defense network against various types of threats (stats from real world). Also have Ukraine, Israel-Iran scenarios. https://airdefense.dev/
I also wrote a longer technical post on the maths behind it: https://medium.com/p/292c755a6ceb.
I'm working on https://www.fluxmail.ai, a modern, AI-powered email client.
I think there's a lot of potential for AI to improve the way we organize and manage our inboxes, while still letting us keep control over it.
What I've learned is that there are a lot of little features that make up a good email client that you may not even think about when using one, like threading, quote blocks, even what email address(es) to autofill when you reply to an email. For an app you use potentially for hours a day, the polish and "last 20%" makes a huge difference - and takes a while to build!
If you have any feedback, especially on what features are most important to you in an email app, I'd love to hear it :)
Disclaimer: I'm making presumptions, since I haven't used the service. Correct me if I'm wrong.
I don't like the idea of a centralized system to flow all of my email accounts through. I think this would work better as a localized agent that runs against my account (more like an email reviewing system vs a centralized email monitor). That would be less of a privacy concern, in my opinion.

[0] My partner has a bunch of handwritten family recipes, so I’m trying out an optional extract from a photo of a hand written or magazine recipe that uses AI. Not required and I may pull it out into its own service that spits out schema.org recipes. We’ll see.
The OCR -> schema.org pipeline would be useful, I've been doing it manually prior to importing to Mealie.
Music player that can organize album collections from different services like Spotify, Apple Music and Bandcamp, Discogs, and show detailed and high quality information that can be searched and filtered.
I didn't check the app but that website itself is nicely designed, clean, with information at a glance, made me think of ways it might become useful to me: and what came to mind was the Bandcamp ticker they have at the frontpage, with albums moving horizontally, that's one of my favorite ways to discover new music.
I’m building a reward chart app for parents. See link below. I just submitted it yesterday for review the App Store and Google Play. Now I wait. Fingers crossed.
I'm building GhanaHousePlanner https://ghanahouseplanner.com/, a web platform to help people in Ghana/diaspora plan, estimate and manage house construction projects. It is free for individuals and only project management and using the floor planner ai agent needs subscription.
Current features include:
- Live material price list updated monthly (based on prices at local shops)
- Conceptual 2D/3D floor plan generation following Ghana Building Standards (development in several phases using procedural floor plan generation)
- Construction management dashboard to track project stages and conversations between project manager, mason, carpenter, etc.
- Printable material cost breakdown

I would love to have feedback, thanks.
Hey, I find it interesting, I will contact you to have a chat
I was tired of repeat, sponsored, and "safe" music suggestions from Spotify, so I built a discovery engine that puts the control back in the user's hands.
The core idea is simple: You define a "Discovery Model" with explicit constraints (specific genres, release years, track popularity, etc.). The app then uses this blueprint to source tracks.
The results are fresh for two reasons:
- "Known" Track filtering: Excludes all songs saved in your library and recent listening history.
- Active Curation: Uses your custom model, not a vague, opaque algorithm.
It’s built with a local-first mentality and a focus on privacy. No black-box AI "vibe" mixes, just pure, objective discovery based on your criteria.
Hope ya'll find some new gems!
I canceled my Spotify subscription because it would not let me "reset" the algorithm to get fresh suggestions.
A "discovery algorithm" that I used (works great for jazz) consisted on looking up which musicians played on an album that I liked on discogs and searching for more albums from them.
Annoying right?
I am also a huge Discogs fan and unheard.fm actually leverages their APIs to aid with discovery ;)

Finally making a simulation of my heat engine. It's kind of like stirling engine, but working on entirely novel cycle, theoretically should be able to achieve over 80-90% efficiency (yes, more than Carnot theorem says). I had this idea for 15 years already, but didn't have enough free time to make prototype. Now I don't have much time, but thanks to AI I have kickstarted simulation program (it told me which equations to use and how, I do most of my programming myself), turns out it's not as hard as I've imagined when you know which equations to use. Still working on it at max several hours a week because I have two other programming jobs. If it works, it will noticeably bump humanity on Kardashev scale.
carnot theorem does not put an absolute limit , a carnot cycle can have any efficiency as long as you have reservoirs hot and cold enough ,
besides that if you could be more efficient than carnots cycle at two temperature you can spontaneously extract heat from a cold object and out it in a hot object without any input energy , this would mean you can have perpetual motion . we are not just going to bump a kardashev scale , were going to truly max out and go beyond.
fun fact the U S patent office has been bogged down by so many perpetual motion applications they have made it policy to outright reject such applications without a working model satisfactorily demonstrating it
It is not a carnot cycle. It will NOT be able to pump heat, it's not a reversible cycle (it's not even a single cycle, it's a series of open-ended heat and pressure transformations). And using a heat-pump will also not make it a perpetual motion. Heat pump can be used as a kind of heat-transformer here, so if you have a lot of low temperature air (but higher than your ambient temp), you could use heat pump to gather energy from that air and present a higher-temperature air for my engine (losing some small amount of heat in the process, but heat pump will reuse heat wasted in it's own electric engine).
It should achieve such efficiency with air heated to 150C and ambient temp of 20C. If you heat air so that it expands more than 2x, it will start to lose efficiency.
BUT - this is all theoretical, I work on simulation that will confirm if it works. It might not, I might have made some big error in thinking how it works, but I searched for 15 years on some way this should not work. I contacted two physics professors specializing in thermodynamics and they couldn't find a way this won't work, both said "Yeah, but to tell more, we need prototype or simulation".
Working on a meal tracking app (iOS/SwiftUI) that helps you understand eating patterns - mood, hunger levels, where you eat, etc. Built it to learn Swift and shipping to the App Store.
Honestly struggling with whether it's solving a real problem though. The detailed tracking with quantities and calories feels like too much friction.
Would love to hear if anyone actually tracks their meal habits and what works for them.
I'm making a game finally! Merge-three + village sim.
Hoping to actually take this one to something polished as opposed to the many half-finished prototypes littering my git repo over the years. I've discovered (always knew?) that heavily cutting scope is the best way, and been successful thus far.
It gets pretty boring/unbalanced by ~150 turns, but I have some ideas on how to fix. I'm still playing with ways to help de-clutter the board and make use of the economy aspects.
After some false starts with ai-gen art, I had fun learning to color the pixels myself. The process wasn't as scary as I'd thought and the results are better than I hoped.

I'm wrapping up a v0 of a personal website soon [1]. This has been kinda "coming soon" for almost 7 years now - every single time I attempted it in the past, I would stop it prematurely due to a lot of yak shaving and I could never finish it fully. Or more commonly, I would get bombarded with busy times as well.
I'm happy where it's landing so far but also appreciate any actionable feedback to make it better (!). Under the hood, it packs a Rust Axum API, plenty of ffmpeg, and some hobo infrastructure [2] here and there.

Working on developing a suite of apps around photography, from cameras to editors and utilities.
The goal is lightweight, composable tools with clean interfaces that respect user agency and privacy, provide technical clarity, and make you a better photographer by encouraging mastery over your tools and offering new ways to approach picture making. Also broadly honoring the (almost) 2 century old history of the craft and drawing inspiration from pre-digital processes and approaches.
Got a number of updates to existing apps and new ones in the works, I’m excited for the full long term vision I have that I plan to sum up in an essay at some point.
Currently Apple platforms only but the plan is also to break out of that down the line.

I've been working on a ttrpg site for the last year with my own IP. The intent is to create an experience that makes an intuitive UI that minimizes tedious tasks.
You need to know "does this guy look hurt"? The enemy HP bar can be set to either an actual percentage, or set to have cracks in the bar to signify a range of damage. Does only person take notes? Personal notes are shareable and there's a section for community notes. Do you have enough perception to notice a hidden door? The UI can be set to go off passive perception and give you those notifications automatically.
It's still in early alpha testing with friends, but it should eliminate general GM pain points to encourage more groups to form.
Currently working on a website that lets you add any form of troll CAPTCHA to your website or allows you to create a redirection with shortened link.

I posted in this monthly thread first time in May when I launched a daily logic puzzle, Clues by Sam. Since then it's grown significantly, and I couldn't be happier!
The game has a farily simple frontend, but there is a fairly complex constraint solving algorithm as part of the puzzle making process. What makes the puzzle quite unique is that you can't "guess". You can only make guesses that are provable by logic. The algorithm ensuring this has worked flawlessly for months now (though I've manually inserted some silly mistakes once or twice).
Today's puzzle is one of the hardest to date. The difficulty resets on Mondays, and then gets harder again towards Sunday.
Clues By Sam has become THE morning fixation in our household since I first heard mention of it a few weeks ago - super fun, thank you!
I left my job to work with the technologies (embedded rust, SQL, custom PCBs, typescript & angular, more rust server side) and practices I'd been dying to use and build a solution for a problem I had. A big part was also the desire to control complexity and lead product direction instead of taking assignments knowing they were the wrong direction for the products and their consumers.

Initially started as an experiment for 10 issues to see ig it gets traction, 6 issues in it’s at 68 subs and probably will continue for unlimited time period.
Link to the latest issue: https://eomail4.com/web-version?p=01b6f55e-bb2d-11f0-bcb3-f3...

I’m building https://unrav.io : A tool to fight information overload.
It lets you turn any article, YouTube video, or PDF into summaries, mindmaps, podcasts, chat conversations or infographics that match how you learn with just one click.
We just launched this week the Chrome extension so you can do all this in one click on any page, no login needed (with generous freemium usage).

Would love feedback from fellow builders.
A few things:
https://terminalwire.com streams a TUI/CLI from web apps without having to build an API and
I recently finished 45 videos at https://beautifulruby.com/phlex, so now I’m talking more about them and
Updating https://sitepress.cc to work with Rails 8.1 and thinking about another set of videos for it at https://beautifulruby.com/sitepress.
I’m building RootCX (https://rootcx.com). A customer "operating system" replacing dozens of SaaS tools.
As a second-time founder, I've watched the SaaS boom create an ocean of best-of-breed tools. Each solving one slice of the problem. One solving it end-to-end.
Now every company runs on a patchwork of apps, APIs, and workflow hacks just to keep customer context alive. It's insane how normalized that's become.
RootCX starts from the opposite premise: the customer is the core, not the app. Everything: CRM, support, billing, workflows, AI, ... plugs into one shared customer base. Less juggling tools, more actually running the business.
This looks cool. But that means people need to use your own apps right and you will have to provide apps for every niche? This sounds a bit like an ERP system, similar to what https://www.odoo.com does.
I'm building an analytics and attribution platform for onchain apps, named Formo.
Think Google Analytics + Posthog designed for crypto users and apps!
I've learned a lot about data engineering and analytics in the past year.
I am working on building neospark - AI native canva
And we are now recruiting our first group of seed users. If you're excited to shape the future of design and be among the first to try neospark, please visit our homepage and join the wishlist through https://useneospark.com/
We'll send you an exclusive invitation the moment our MVP is live.
I’m developing a Mac desktop application that allows you to rewrite text using any LLM (via OpenRouter). Currently, users select text, copy it, and activate Cliptomic with a designated shortcut. The application then rewrites the text and replaces the original content in the clipboard, enabling easy pasting of the improved version. This project is still in its early stages: https://github.com/PaleBlueApps/cliptomic
I'm atm working on a couple of things, first the biz, a self-hosted home server OS that simplifies Docker management and provides a unified dashboard for running services at home. The goal is making self-hosting more accessible without sacrificing flexibility.
And also building as a hobbie a procedural universe generation engine that simulates galaxies, solar systems and planets in real-time. Everything is generated from a seed with actual orbital physics, seasonal changes and so... Built with Python/Flask backend too but Three.js for 3D visualization and React instead of Vue3 as in the prior one. Think No Man's Sky vibes but as an explorable simulation engine really D:
Mockaton. An HTTP Mock Server with a dashboard UI for changing mock variants on the fly. For example, for testing retries.
I'm working on a paragliding track visualizer: https://skyviz.io - I started it just for myself, then it kind of got out of control, and now I'm spending wayyy to much time on it After many years of working on enterprise crud apps, it's so refreshing to actually use some maths and 3d programming again :D But now it seems the the only way forward to make more out of the product is by doing marketing... Something that is absolutely NOT my area of expertise nor interest
A website that lets you match watches with different straps to get a feel for how it'll look.
Mixing and matching watches with different straps is something that I really enjoy doing. It's not often easy to tell ahead of time whether the combination will work.
Making advanced multiphysics simulations and optimizations accessible through a simple web interface and AI chat agents. I’m building SimuPort (https://simuport.com ) to lower the barrier to running and iterating on complex simulations. I’m interested in hearing from anyone who has needed these kinds of simulations in practice (e.g., optimizing airflow in devices, analyzing thermal–structural interactions in prototypes) or who has experience with tools like Ansys, OpenFOAM, COMSOL, SimScale, or similar. What worked, what didn’t, and what’s still missing?
https://fooqux.com/ - an experimental tech article aggregator. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website.
The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc.
I hope this service might be useful to others as well. You can sign up with github account to submit your articles as well. I would appreciate any feedback.
I am working on methods to automate my VC firm. We have a small team and many different tasks to do. I’ve had success with using LLMs to help us automate various projects. But I appreciate any open source tools, techniques, readings, etc. if anyone knows any!
what sort of tasks are you trying to automate?
I've been working web scraping using LLMs, I just shared one of the libraries I created to get structured data from arbitrary pages: https://news.ycombinator.com/item?id=45870231
Instead of sending the page's HTML to an LLM, Hikugen asks it to generate python code to fetch the data and enforces the generated data conforms to a Pydantic schema defined by the user. I'm using this to power yomu (https://github.com/goncharom/yomu), a personal email newsletter built from arbitrary websites.
Porting LevelDB[1] to Seastar[2], for internal metadata storage in Redpanda[3]. Before you ask why can’t something off the shelf be used, seastar has unique constraints around its runtime and its memory allocator that means we can’t reuse an existing library.

I'm building a better language learning Chrome extension. I wanted it to offer not just tools, but also the best Comprehensible Input practices.
Here’s what I plan to add that other tools don’t have:
- Super smooth Anki integration — saves words/sentences with full video context, native audio, screenshots, etc.
- A structured way to improve step by step.
- Real dictionaries for each language (as long as I can afford them ), not just AI translations.
What I’ve built so far:
- Word meanings in real context
- Real-time subtitle translation
- Auto detection of common collocations
- Target languages: English/Spanish/French/German/Japanese/Korean/Chinese. Native languages: English and Chinese.
If you also like learning languages through videos or podcast/audiobook, I’d love your feedback and ideas!
Decompiling Snowboard Kids 2 for the Nintendo 64! https://github.com/cdlewis/snowboardkids2-decomp
The work is mysterious but important.
Basically small data tools for myself.
A non-bloated HTML, CSS and pure Vanilla JS framework to create dashboards.
A cross-platform JSONL viewer where I am learning ImGUI. Haven’t found any other open source GUI framework that‘s small, provides out of the box components for tables, sorting
Im finalizing the Google Calendar integration for Ganttify. https://gantt-chart.com
It will allow users to fully manage their calendar in a Gantt chart. Complete with customizations like dependencies between events, custom colors for time blocks and custom icons for single-day events (“milestone”-like).
Ganttify is a Gantt chart add-on for web applications or services that can benefit from a Gantt view. My goal is to expand the number of integrations for Ganttify and release a new integration every month or so. If any of you have an interesting (niche or non-niche) idea to integrate Ganttify with feel free to contact me.
Added compression to my metal 3D printer slicer exported CAM files, and refactored the code to better support larger volumes.
Tweaking the piezoelectric driver PCB design for the micro-positing microscopy stage project. The Nanomotion piezoelectric motors were not meant to be used in the manner I chose, but it is fun to push the limits of technology.
Finishing up some custom 1U mounted hardware, and getting a batch of test PCB soon. Bend radius came back 1mm oversize, but this was acceptable for a single run item.
Also involved in several other projects maybe 3 people would care about. Doing a custom FPGA PCB is not very fun unless encountering that rare class of problem CPU/MCU simply can't handle cleanly. =3
I am working on a home-oriented solution (hardware box + software) for backups of the media files from phones. The solution facilitates having a separate backup drive (stored in a closet) in addition to the primary data drive in the box.
Hi David,
Fran here. I'm building a niche tool for designers and architects to create AI renderings in seconds with no prompting skills, no ComfyUI installs, no chasing the latest Nano-Banana, Flux, or any other GenAI image model. I called it RenderAI. Want to make it simple and fast.
We already have thousands of users, which confirms there is a real need. Still, I’d love to get honest feedback. How can we stand out? Feel free to be blunt.
Check out https://RenderAI.app if you’re curious.
Just published the Halo vision headphones [1]. Currently working on reducing parts where possible, tuning audio quality and video stabilization.
Working on AI interpretability infrastructure! Starting with hallucination/failure mode detection and causal tracing in transformer-based foundation models. It's non-SAE, domain-agnostic, and works for any kind of tokens or sequence data (e.g. not just English text - biological sequences, physics data, etc). Some of our early tests indicate that this detection setup could broadly work well for any property, but we've mostly validated on hallucinations. If you have access to self-trained or open-weight models, would love to have you try out the alpha version - running it through HuggingFace!
OpenSOHO: built to manage a small number (from 2 to ~20) OpenWRT 24.10 based network devices. https://github.com/rubenbe/opensoho
I have been tinkering on a little price drop alert scraper written in Python. It's run as a cron job, and every day it checks the prices of a list of urls (my clothing staples from various outdoor retailers, mostly) and sends me an email with any products that have gone on sale.
I've been running it for over a year, but now I have fixed it up and made a little landing page to see if there's interest for a stupid-simple price watch service like this (no need to install an extension or create an account):
I've been working on a little game for my daughter to help her learn the movement of chess pieces. https://www.minichessgames.com
It's currently just a "maze" type game where you have to get to a goal square in the minimum number of moves (there are rocks placed on the board to act as obstacles)
I'm in the process of making some very simple games like battling knights where they leave poo and you try to trap your opponent.
Fun making it even if it's just the two of us who'll enjoy it :). Partly I wanted her to learn that you can create for the internet not just consume...
For the past few months, I've been building a health tracking app called LogBuddy. I got tired of using separate apps for nutrition, workouts, weight, and period tracking. So I built LogBuddy to handle all of it with a dead simple interface. That way, all the heath data I'm tracking would be in one place. Right now there's an Android APK available. If there's interest, I'll publish to the Play Store and build an iOS version too.
Would love to hear your feedback if you try it out!
Here's the github repository: https://github.com/aabiji/logbuddy
My custom poker study tools:
https://poker-study.onrender.com/
I really like the range memorization tool from GTO Wizard, but want to be able to put in custom/arbitrary ranges to test. I also want to be able to import and simplify ranges from other sites. Work in progress, but every scenario is url encoded (warning: subject to future breaking changes) and I use those urls in for links in my Anki decks.
I suspect AI company want improved efficiencies and developing a framework that can be applied in determining the minimal-energy, maximal-efficiency architecture for ai models. Calculating the precise limits, like a Cognitive Event Horizon, where a model becomes so complicated it literally costs more energy to run than the knowledge it provides, and the Semantic Horizon, where it simply gets too complex to be accurate, etc. Lots of cool implications such as around a fundamental mathematical maximum learning rate which results in trying to get anywhere close to that that by doing stuff like aggressively filtering of the data.

A tool that detects potential signs of overwork in incident responders, which could lead to burnout. To compute a per-responder risk score, it integrates with Rootly, PagerDuty, GitHub, and Slack.
We offer both a hosted version (https://oncallburnout.com/) and a self-hosted one (https://github.com/Rootly-AI-Labs/On-Call-Burnout-Detector).
We are building https://desplega.ai which is a QA agent that help teams ship fast without compromising quality.
We focus on making it as fast as possible, integrated into CI, MCP for local dev, and support both an autonomous (we call it discovery) and guided test creation approach.
We believe that in the era of vibe-coding, quality is key, as we are lazer focus on building a solution that scales with your product, and removes the burden of QA from your team.
Technically, we built an in-house engine that is in charge of generating the tests, that speeds up and gets better the more you use it.
I'm working on some documentation for my framework/ide (https://glitter.nz). I'm thinking about all the new things I'm really hoping to add.
Currently building a service around the domain https://ScamAI.com
the service is a suite of online vetting and due diligence tools for website flippers, Fb marketplace sellers/buyers and Tiktok shoppers
The domain has an interesting backstory. I acquired if it n 2022 from Epik after they stole the $10,000 I had deposited into their Escrow service. The money was meant for acquiring a newish stable diffusion hosting website that was competing with civit.ai. When the Epik issue was discovered, the seller pulled out.
Acquiring that website could have changed my life.
I'm working on a lightweight next.js alternative named after my dog: https://github.com/davedx/dex.ts/
It's going fairly well, I'm more or less as feature complete as I want to be. I might do something addon-like at some point to make scaffolding apps with shadcn, tailwind, prisma and friends a single command. Like shadcn does with components.
Feedback welcome!
Building a docs website [1] for my speech-to-text CLI tool, hns. I use it 5-10 times daily to transcribe my voice, and a few developer friends I've shared it with have also adopted it for daily use. They like that it runs in the terminal and keeps all data local. So, felt like I should write down guides for new users to get started quickly and to highlight key use cases.
Building this documentation website using Docusaurus. This is my first time using Docusaurus, and it feels like a very nice tool for quickly developing a documentation website.

What I am working on is my masters thesis in bioinformatics supports/HPC: "Predicting the running time of bioinformatics tools", by running (initially) 5 tools 1000 times each with different parameters and then fitting a curve.
I am pretty sure I can get 70% predation rates +/- 10% . Unfortunately, I'm blocked by the lack of hardware. Kind of not-quite school affiliated (so I cannot really ask for national computing resources), so I am trying to build a single threaripper pro node on my own. Hurts the wallet, but if added to slurm as module, this can have implications.
I really missed an old mobile game that got de-listed after the devs sold it to a company that subsequently ruined it. I'm a full stack dev, not a game dev, I don't have time to learn the ins and outs of Unity so I tried to see what was feasible in the web world with Babylon.js + React + Capacitor.js and I'm pretty astounded at how well it works out.
I've been posting a bit on https://www.reddit.com/r/BlossomIdleGarden. I plan on opening up a beta later this week.
I'm working on an app to display charts, analysis, and data on English football league games.
The real goal is to figure out how to use code gen AI (Cursor) effectively for data science projects and to figure out rapid deployment. I'm pushing things a bit harder than you typically see in demo apps (e.g. different chart types (e.g. violin plots, heatmaps, line charts), interactive charts, JavaScript widgets interacting with Bokeh charts, etc).
I'm trying to figure out all the skills, processes, and training you need to build a technical app very quickly. I'm at the deployment stage now.
I'm working on Fillvisa.com - a free, browser-based tool that lets you fill complex U.S. immigration forms (like DS-160, AR-11, I-90, etc.) entirely in your browser.
It mimics the official USCIS forms but autosaves locally, validates inputs, and lets you download a ready-to-submit PDF - no signup, no uploads, no tracking.
It’s meant for travelers and immigrants who just need to fill a form once, and as a side effect, it’s become a great acquisition funnel for my paid B2B product, VisaSimplify, which helps immigration lawyers automate client intake and PDF mapping.

A custom provider for kubernetes cluster autoscaler for homelabs that lets you turn on and off the nodes without reprovisioning them.
https://github.com/homecluster-dev/homelab-autoscaler
https://autoscaler.homecluster.dev
Works with any mechanism to turn on and off nodes(IPMI, WoL...) I have some nodes that I turn on and off via a curl to homeassistant to the power plug.
Been working on a native iOS client for Bluesky. Liquid glass design, and trying to make it feel much more native than the standard client.

Have about 100 spots left on my current TestFlight if anyone is interested: https://testflight.apple.com/join/RRvk14ks
I've created an AI-assisted writing platform, that doesn't generate text, but instead lends focus to human creativity, and have AI assist you instead of trying to replace you.
You create a writing style via existing text examples, blog posts or URLs, and Arcitext extracts a "writing fingerprint" which it benchmarks new text against.
There's a solid Markdown Editor with tools such as Tone Fit, Rewrite suggestions and Fact Check, which helps you when you need it.
Kind of like having a writing coach and content strategist on speed dial.
I'm working as a school teacher of Computer Science for Year 6..9. Currently I develop an online collection of exercises for intro to programming.
I have exercises:
- on turtle, using my DSL with three commands: 4[100 r90] draws a square
- on robot (blockly)
- a 2D replica of Replicube to teach conditions in JS.
I've started vibe-coding it two months ago and I add new stuff whenever I need it for my classroom.
I'll soon add signups.
The platform will be free forever, monetized via banner ads somewhere in the future. The target audience is middle school teachers of CS.
An OpenAPI code generation framework for TypeScript called Skmtc (pronounced like "schematic")
It handles the complexities of parsing OpenAPI and rendering output code, while providing the end user with full control over generator code via string templates.
Imagine something like React but for code generation where each code generator can compose its own output using the outputs of other generators.
A Mac-based video manager that automatically transcribes, translates and summarises videos. I process information best through reading, so I built it to manage my growing collection of training course videos, webinars and meeting recordings. Currently working on adding RAG search to make it easier to query content.
Also building a CMS and static site generator that runs entirely client side in the browser. Pick themes, model content an publish to clean HTML. It also makes content available beyond just the browser, eg in a command line TUI.
Originally started in 2012, I’m (still) building log.soccer - a stat-tracking tool for amateur soccer players. This is the third or fourth iteration of the site, which until this year mostly served as a glorified résumé project to showcase the latest framework or tool I had just learnt.
Thanks to ChatGPT, my productivity went through the roof this year, and I finally shipped an MVP that might actually be useful.
It’s a standard Django + React + AWS stack. My raison d’être is to build an Apple Watch app that tracks match scores in real time. 2026 hopefully.
Using AI to predict professional sports outcomes.
Working on https://tinythoughts.app, a self-messaging app
Today, I am implementing tag-triggered webhooks so they can get triggered based on the tags assigned to messages.
Use case: for example, I want to auto-tweet all my advice messages and auto-create linear tasks for `company` todos, auto-start a cursor agent when I tag messages with `Cursor task`
For some reason, I got 16 users out of nowhere, so I added a landing page last week. The connector marketplace is next, so that I can share these sub-connectors with the other users. Need a couple more weekends.
Would like to have more info but landing is empty And I don't want to provide my number unless I'm sure it's usefull
Agreed with syabro, this sounds very interesting but don't want to give away my number straight away without seeing anything.
OAuth is here to stay for major email providers (Outlook, Gmail, etc). Microsoft is dropping support for standard/basic authorization in April 2026, and Google has already done this. But plenty of devices and systems don't (and may never) support OAuth.
Auth-Email is a relay that lets you continue using traditional email auth methods even when your provider requires OAuth. Lots of other more advanced features too: all OAuth grant types, add-ins to modify behavior and lots more.
Being an internet radio enjoyer I was always dissatisfied with the state of radio apps. Most of them want you to pay for a subscription to be able to curate favorites and persist them. With nostr we get auth, persistence and social for free.
This version is a rewrite of an earlier one and I've added some cool convenience features like "now playing" and musicbrainz integration for remembering songs.
Spec, flow and most of the UI are done. I've managed to build an Android App yesterday and will publish source soon.
Hey everyone! I built a site that shows your next age milestones, all on a single page. You can see your next milestone age for each type (like your 10000th day) and save it to Google Calendar.
It looks simple, but I learned a lot building this site:
* To calculate age in planetary years, I had to look up their orbit and rotation info
* The lunisolar calendar took me quite some time to figure out (it is not the same as a lunar calendar and even changes by country)
* Adding the dog and cat age equivalents even led me to cubic splines
Link to the site: https://ageequivalent.com/
I'm working on a _boring_ business - a CRM for pilates and yoga studios (https://www.usemojo.app/en). Most tools in this space are bloated or built for gyms, not for someone juggling reformer classes, cancellations, and back-to-back privates.
It started when a friend who runs a studio showed me her system: printed calendars, WhatsApp messages from clients at midnight, and sticky notes for who paid. I'm trying to make something quieter. It should feel like an assistant, not another tool to manage.
https://github.com/superegodev/superego
An open-source, local database which collects all your personal data, hooks it to an LLM (BYO), and gives you an assistant that can answer any question about your life.
It also allows you to vibe-code (or just code) small apps on top of your data (e.g., your custom dashboard for your expenses).
I have a short demo here: https://www.youtube.com/watch?v=gqAyvENDjSA
I am working on a web app that doctors/NPs/PAs can use to automatically rewrite complicated and verbose medical progress notes. The amount of time medical providers spend on documentation is ballooning, and only a small portion that time is actually spent doing medical decision making. The rest of the time is spent incorporating (ie copy editing) data as it comes in from imaging/bloodwork/consultant advice. The goal is for the app to be:
entirely self service, without needing EHR integrations
able to persist and reuse the user's writing style, without actually saving any of the notes
HIPAA compliant (obviously)
I created a media editing app that lets you do some of the most common video editing tasks (cut, resize, compress, blend audio etc). It's browser based so your files never leave your machine and is very fast (leveraging the latest and greatest libraries such as Media Bunny).

On and off working on the Navigation API for Node, Bun, Deno, & as a browser polyfill.
Has 90% test coverage, makes use of web platform tests to verify compatibility, and is in use by some larger companies already with the Navigation API soon to become a baseline in evergreen browsers.
The Navigation API effectively is async state navigations. The likes of React has recently added Navigation API support to make use of the browser reload indicator.

Just got a 3d printer (Bambu a1 mini) and my girlfriend brought home a whole bag of plant cuttings. Thought I would give a modular plant pot (i.e with elements that allow for expanding the pot) in fusion 360 a shot.
I’m working on an AI-powered page optimizer for SaaS & eCom sites: https://peakagent.ai
No complex setup – drop in a script, keep your existing stack
Auto-generates variants for hero, copy, CTAs, and social proof
Continuously tests and routes traffic to the best-performing variants
Optimized for key pages (pricing, signup, product, checkout)
Reports focused on conversion & revenue lift, not just clicks
Would love feedback, tear-downs, or ideas for must-have features before you’d trust this on your main pages.
PS: Deeper ad→page→revenue attribution + personalization by segment coming soon.

Working on Astrology App - https://bestkundli.com
There have been a few astrology apps, but all require you to connect with an astrologer or a pandit. This market has been in past and today, a market of exploitation for the innocent.
So, I built this app to let people read their birth chart with detailed analysis, without any such thugs. There are a few very talented experts, but they are either very expensive or difficult to find. So, it came out of necessity.
I would love your feedback on trying it out and letting me know your thoughts.
Cheers
The functionality is good sir, bt the UI feels more like a generic SaaS application. Thre aren’t many design elements that relate to astrology, so the visual experience doesn’t match the theme. The idea itself is great and with a more astrology-focused UI, it could stand out even more
Did any astrologer predict we would get ChatGpt in 2022?
Ray Kurzweil
Building https://ottex.ai - a native MacOS app to solve repetitive micro tasks on a computer.
- Transcribe voice to text (especially useful when you need to explain something to Claude code )
- (soon) select text to instantly Check grammar / Improve writing / change tone of text
- (soon) select text to Translate between languages
I discovered that I have a few 10/20$ subscriptions (grammarly, raycast, wisperflow) that do embarrassingly simple stuff I can one shot with cheap SLM. So I decided to build a one app specialized in small repetitive tasks on computer.
I am working on a repository for AI Intent Driven Development at https://github.com/Exadra37/ai-intent-driven-development/.
An Intent is a self-contained document that describes a user request. It is composed of three main sections: WHY (the motivation), WHAT (the requirements, often in Gherkin language), and HOW (a detailed, step-by-step implementation plan defined with tasks). This approach ensures clarity and alignment before any code is written.
An AI (not LLM, but image-based one) based tool which transforms photos into visa compliant photos.
You take a selfie, pick document type (China Visa online, Green Card lottery, etc) and the tool knows what size it should be, head height, shoulders position and other requirements. AI is used to detect head position, emotions, objects and other details to provide better recommendations
Check it out and let me know what you think: https://ishotaphoto.com
I made a HN-like discussion forum for (meta)science.
Most (meta)science discussion is either fragmented on Twitter/Bsky, or a bit too formal. I thought a centralised place for deeper, casual discussions might be helpful, so I'm testing that theory.
Launched a few days ago, so it might have some rough edges. I'm considering making it user-invite-only soon, but for now it's fully open for signup. I'll also move it to its own domain once I think of a better name.
Building an ai powered threats deception proxy. A dynamic honeypot system that uses AI to mess with attackers.
When someone tries to hack your app, it detects them and serves up fake responses designed to make them think they're getting somewhere.
The system learns from attackers behavior and serves ai generated decoys to waste their time and frustrate their efforts.
It's basically a trap that gets smarter the more attackers poke at it.
MVP version at https://github.com/0tSystemsPublicRepos/IfritProxy
Brilliant.
Software to track wealth (net assets). All GUI. Using Delphi and compiling for macOS.
Also learning Zig. Would be cool (but a huge effort) to port Delphi’s VCL or Lazarus’s LCL to Zig and create a RAD environment.
I am building Mizu, a lightweight web framework for Go that aims to keep things simple and Go-first. Everything is written in plain Go with no hidden abstractions, and you can start with a single file then grow into a full project without changing your coding style. The name means "water" in Japanese; the framework tries to flow with your code rather than force its own patterns.
I just launched my first iOS app - yes it's a todo list app, but it's clean and simple without any clutter.
I have looked for an app that could give me exactly this for a long time but i couldn't find one i liked, so i made my own.

Still hacking on some data tools:
DuckDB for stream processing:
https://github.com/turbolytics/sql-flow
Lightweight kafka stream processing using DuckDB as the execution engine. 300MiB runtime can easily handle thousands of messages / second.
Working on a Kafka Connect alternative:
https://github.com/turbolytics/librarian
Right now mongo replication (through changestreams) is supported to kafka. Working on Postgres support right now.
I created a RescueTime alternative for KDE Plasma. It runs in the background as a daemon and records time spent on each window in a SQLite database. Next step here would be to add a Firefox extension, since a lot of my time is spent browsing the web.
Tracking windows on Wayland is hard because the protocol doesn't support it. I hacked together a script using Claude Code that somehow works, but I barely understand how.

I've been exploring getting some deeper experience with Claude Code (my org only allows Copilot) and exploring vibe coding by using CC to design a functional programming language that transpiles to JS and build out a full language specification and the tooling to go along with it. I haven't pushed anything to Github yet but it's been very educational, and also a little terrifying to see how easy it is now to produce tens of thousands of lines of code that you totally don't understand.

Right now my app allows users to export build metadata as JSON which can be interpreted by LLMs for analysis, but I'd like to have this work on-device.
https://www.ottoclip.com - Create product-focused content that stays in sync with your product.
Create a script for a product demo or tutorial for your app using an extension. The script is used to generate your product content in multiple formats (narrated video, interactive demo, looping animation, and in-app guide). Whenever your product changes, just update the script and regenerate everything. No manual re-recording of video, syncing of audio, or any other post-production steps.
A TUI to monitor your OpenAI and Anthropic usage inside your terminal.
https://github.com/htin1/toktop
I use codex and claude code daily, also build apps with openai and anthropic api keys, so i always go to openai dashboard and anthropic dashboard to track my usage. Since I spend most of times inside cursor or terminal, I wanted to quickly check my usage without leaving my terminal/ide, so i built this!
It's open-source, MIT, and built with ratatui (awesome name).
I'm building my take on a low-touch task completion assistant designed to counter distraction and hyper-habituation.
It's starting off as a MacOS app because that's the machine I have. I didn't know Swift or SwiftUI when I started. I now know them somewhat, but the entire app has been vibe-coded. This has made it slow going. Very "1 step forward 2 steps back" until I switched from Claude Code to Codex and GPT-5.
I'm hoping to start an initial beta within the family in the next week or two, and then a wider round in January.
I've been building SageNet, a voice-first AI coach that turns your goals into structured, adaptive learning plans.
After a 2-minute voice conversation, Sage generates a personalized 6-module roadmap with build-first projects. It checks in by voice, analyzes your reflections, and regenerates your plan if needed. You can invite friends to your Support Squad for accountability.
The biggest insight so far is people don’t want “infinite content.” They want structure and someone who remembers them.
would love feedback!
Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.
Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.
I built a wireless highlights & annotations export service for Kobo e-readers earlier this year [1]. Had a free tier limited to 20 exports but wasn't sure how to price it beyond that, so I just left it. Recently a user reached out asking if I'd settled on pricing and how they could pay for unlimited exports! That jolted me into coming up with a price, and now I'm finally getting Stripe integrated :)

Making the Nest 2nd gen thermostat the Google recently bricked compatible with local setups like Home Assistant.
I'm involved in 3 projects that are solving this problem from different angles:
UI exploration for interacting with LLMs
https://www.youtube.com/watch?v=ldJTjwhqKy4
Currently popular AI chat interfaces feel restrictive when exploring or learning complex concepts/ideas. I often want to revisit earlier parts of a conversation, ask branching follow up questions, connect related concepts, compare and contrast between various chain of thoughts. This UI exploration aims to solve some of these limitations.
very very cool .
I am currently working on a breastfeeding tracker for Garmin devices. It is already released a time ago, but I want to include a companion app for this app.
I used it with my first child, and it helped me greatly. After releasing the support has been amazing and I recently passed 1000 downloads :)
I am hoping to extend the functionality with more insights and helpful tips (double-checked with professionals) to help young parents with the beauty of breastfeeding their newborn children.
I recently became unemployed so I am building a tracker for all my job applications what stage I am at in each process that kinda thing
It’s no where near done
But as always I am also building https://retro-board.it for doing retros and sprint poker
And https://flags.gg for feature flags with quite a lot of agents (rust, go, react, and others)
It may sound absurd: But a website in which people can set their availability on a calendar. Kinda like Doodle. My requirements are: - no account necessary - timezone support - not have to pay for it Basically impossible to find something which fills those requirements. So I am coding myself a handy tool. For what? To coordinate people for the game Foxhole to take responsibility for certain areas so we always have a General Manager online
I absolutely hate Doodles mobile UI, this would be great.

I built an AI-powered voice agent to help people prepare for the IELTS english exam -- specifically the speaking portion.
- Realistic exam conversations with natural follow-ups and questions to challenge your viewpoint
- Get scored on all 4 criteria (fluency, vocabulary, grammar, pronunciation)
- Instant feedback on where to improve
- Free credits to start
There are many existing resources to help prepare for the IELTS exam, however the options are very limited when it comes to practicing the speaking portion.
Ultra low-power LoRa stuff with STM32 microcontrollers. Powered by solar.
Oh nice! What protocol are you using?
For the usual sensor stuff I stick to classic LoRaWAN. For "complex" protocols I prefer the TLV style.
Biggest trick is incorporate deep-sleep as much as possible and "waking up by interrupts". That has a big impact on your software designs.
I am building a foundational layer for building C++ apps using Bazel.
I am working on creating a standardized set of paths and third party libraries that work seamlessly across multiple developer teams. Allowing library upgrades to happen transparently in the background. This will enable developers to focus on business specific logic and not have to worry about the intricacies of the build system and allowing to "magically" work in the background. This is allow foray into Bazel and using it as a learning exercise to master it.
I am working on a time tracking app. I use it to keep track of time spent vs my estimates, and also just to check my actual working hours. It's fully local—everything is stored in localStorage — but I do have plans for some optional syncing so it can be used on multiple devices.
It has helped me a lot to keep focus while working and track distractions. It might be too tailored for my needs, but have a look: https://zookeeper.fyi
I'm working on aggregator of curated technical content https://devblogs.sh.
I started it a couple of years ago as personal project to help me study for interviews. Back then, it was simple RSS feed aggregator of big tech companies engineering blogs.
Recently I expanded content library to technical conferences and indie blogs, and implemented semantic search in all the library (for example, you can semantic search by all Strange Loop videos archive).
Give it a try!
I'm working on a video / post on how to solve the 1 billion row challenge (https://github.com/gunnarmorling/1brc) and get a competitively fast result while keeping the code readable and maintainable.
So far I'm within spitting distance of the winning entries without using any unsafe code or bit twiddling tricks or custom JVMs or anything like that, and having all the concerns nicely separated and modularized.
Excited to share soon!
Nonoverse[1], an iOS puzzle game about nonograms (image logic puzzles).
So far all levels have been handmade pixel art. I’m now testing machine generated puzzles with random “pixels”. This is an interesting challenge because I still want levels to be solvable and fun. I recently released 15 new puzzles like this and I’m preparing a new update with more.

Started a web design agency that makes professional websites for small businesses:
Also working on a calculator app that can be resized to large sizes (think half screen on Mac), because I can’t work with small calculator apps on my Mac.
I have started working on https://framebench.dev
This is going to be a small side project which shall include utilities for working with automotive diagnostics and logging workflows.
I have to do a lot of this in my day job and that's where the idea comes from.
Disenhackifying one of the last pieces of my KaithemAutomation server that still feels not best practicesful.
Device driver plugins used to have a very simple flat key value, strings only format, with a set_config_properties function to tell the host what kind of UI to show.
That's all getting replaced with JSON schemas, with some auto-upgrade shims so old config keeps working.
It's one of many things that now seems completely insane, but made sense when I had way less experience a long time ago!
Also still on and off working on my BLE/WiFi based Meshtastic-alike.
I'm working on a poker server to allow holdem bots to play against each other (https://github.com/lox/pokerforbots) and a Pluribus-level bot that plays on it (https://en.wikipedia.org/wiki/Pluribus_(poker_bot)).
Enjoying writing some really fast Zig implementations of hand evaluation and CFR-based solvers.
For the first time in years I'm working somewhere that doesn't use JIRA or Trello and find myself without a Kanban system. I'm having serious withdrawals. I have limitations on using a non-approved IT system because I use customer data so I vibed a PWA Kanban system. Stores data in browser and only vanilla code. No external dependencies.
I’m building a typed, array-oriented dataflow compiler that takes small declarative schemas and emits plain Ruby and JavaScript, with a C path. It has a mid-end with inlining, common subexpression elimination, constant folding, dead code elimination, loop fusion, and LICM.

Working on cross-flock discovery in sanctum [1] so I can cut a 1.0 release hopefully before Christmas.
I am always looking for more people to test and play with it or even review the code. We've got a nice little user community going.
Usually this comments drowns in the crowd of the massive amount of awesome stuff people are building, but if you find sanctum useful, hit me up. Good things are happening.
Stay happy
I created a small / 20 line Jupyter notebook that uses the Nthesis api which shapes, tags, and makes the data searchable, chattable and allows you to visualize relationships / data clusters (yep lots of games this month!). https://nthesis.ai/public/hn-working-on
I've always loved the "What are you working on" post. So many niche and interesting projects!
Problem: I collect a lot of music I come across in playlists on Youtube/YT music/Bandcamp, but tracks often disappear for various reasons.
Working on: Offline Youtube playlist download manager. It uses YT-DLP to get all my music and then enriches artist/track metadata using MusicBrainz, AcoustID, Discogs, LastFM, Spotify. Runs as an offline webapp so I can browse and play music locally. Might play around with recommendations for fun later.
Happy to publish the repo if anyone else would find this useful.
We are close to landing our first customer - an enterprise-level one at that! We're Geneva Business Messaging, a tool to centralize, persist, and if necessary escalate critical interactions between large companies and their partners. For actual collaborative cross-company work in fields like engineering, logistics, or security - not spam, marketing, sales, or the other frequent purposes of B2B apps.

I'm building an app that helps users memorize Kanji and vocabulary with AI-generated visual and story mnemonics.
Right now, I'm adding a feature to practice writing Kanji and another that creates AI comics based on vocabulary you've learned.
Me and my friends are working on a fitness companion app, used for tracking both nutrition intake and workouts. Taking the best from well known nutrition apps and workout apps like Hevy. In the core of it will be an AI Agent which can analyze the overall progress based on food and exercise logs and give personalized suggestions.
Maybe a bit too complex project for me to handle but hopefully will take it somewhere
I made a direnv-like utility which hooks into your shell to allow using Nix flakes for dev envs / dev shells anywhere:
https://github.com/dfrankland/envoluntary
This helped me bridge the gap between installing packages declaratively via NixOS / home-manager and defining them for each project being worked in via flake.nix / direnv / nix-direnv; which was needed since most projects don't use Nix.

I'm working on an alternative for Quora/StackOverflow. It's everything i like about those two platforms but without the lock-in/giving them all intellectual property rights.
Main idea:
- Portable identity - Your data/posts/reputation is yours - Client choice: Use any nostr client to reply from/to - Open ranking/Anti-Spam: Web-Of-Trust/Global pagerank - Zaps/Payments weigh more than likes (likes are cheap)
I’ve built two AI agents that curate personalized news:
- Market Pulse Agent — analyzes the last 24 hours of global and US market news to generate actionable stock-trading signals.
- TechPulse Agent — tracks emerging tech trends and surfaces interesting GitHub projects and engineering updates.
Both are live on my site: https://kryptunes.com
Still iterating, but the goal is to build a fully automated, AI-powered research companion for traders and tech enthusiasts.
A modern QuickBooks, based on beancount, WorkBill (https://workbill.co). You can play with it at https://demo.workbill.co.
Unlike traditional accounting platforms we expose the ledger model directly which enables our customers to model complex transactions even when we do not have direct support for it.
Been working on this for a month, and it uses Elixir, Phoenix and InertiaJS with React.
XferLang, a data-transfer and configuration language to serve as an alternative to JSON.
Most obvious features, at first glance, are no commas and no need for escape characters. Other useful features include processing instructions, extensible data-substitution rules, and support for comments. Currently only implemented in .NET; plans are to rewrite the core in Rust and provide language wrappers around that core.
Working on a budgeting app which uses interactive sankey diagrams.
It has some dynamic features like sending excess cash or taking missing cash from somewhere else, making it quite useful.
Also, you can connect with our partner or flatmates for shared budgets.
I am actively using it myself together with my girlfriend, and adding new stuff as our demands for budgeting become more elaborate!
Something fluffer. Sankey diagrams will never live that down lol
Haha, didn’t know about that, maybe I should use that as the example on the landing page :D
I'm working on vorfract, a voronoi voxel world:
Just shipped Scrype, a library for devs who want a cool way to showcase their code.
It's fully typed. Works with vanilla JS, Vue, React, or just a script tag.
Got some feedback that it may not be the best UX-wise but let me know what you guys think!
Demo: https://devjeff.info/scrype Repo: https://github.com/DevChanQ/scrype
Next release of my app (8 years since initial release) - adding minor features and minor bugfixes.
Video Hub App - browse your local video files with a beautiful interface (and scrub-able thumbnails to see multiple screenshots)
$5 for anyone https://videohubapp.com Free for anyone https://github.com/whyboris/Video-Hub-App
https://lunchtrain.se/ A one glance page to find what to eat for lunch in Lindholmen, Gothenburg, Sweden
Working on this made it really clear to me how a LLM can bring real value to a backend, it excels on processing very differently structured dynamic data (something if done without an LLM would require quite specific code - which would lead to more development time and increase time to market)
Rates your sleep, tracks sleep debt, and tracks how workout timing, coffee time, AC temperature, etc influence your sleep.
2.0 is in review - adds support for recovery (based on sleep HRV, HR), and strain.

I'm working on a web app that creates easy-to-understand stories and explainers for the sake of language learning. You can listen in your favourite podcast app, or directly on the website with illustrations.
Most of the testing so far is English/French/Japanese/Mandarin, but I'm eager to add more languages if anyone is fluent and willing to help me evaluate the text-to-speech.
I'm starting to shift my energies towards building more hardware and less web/mobile apps for side projects.

Looking at an ancient game called Trias/Ternii Lapilli and learning/using maths to figure out if it can be solved https://tom-dickson.com/blog/trias-game-investigation/
It’s similar to tic-tac-toe but slightly different of course.
Found it a great opportunity to learn about new areas of maths. Trying to figure out where to go next with it.
Correct and performant way to calculate historical value of a portfolio. I want a pure function, but taking a date as input is insufficient because users can edit holdings, and securities can split.
Weighing the tradeoffs of doing this calculation server or client side. That'll be an architecture shift away from my current set of background jobs fetching state and towards something more functional and on-demand.
Currently building a terminal based file organization tool using AI, the scope is simply to organize files in a folder based on the file content, its open source and contributions are welcome: https://github.com/adefemi171/ai-rganize
I am building https://pagereport.app where you can talk to agents purpose built to help you improve your conversions from your landing pages but at fraction of the costs.
I aim to make it into a agentic system that provides you expert level CRO analysis but at fraction of the costs then those expensive CRO consultants
I’m working on a games website called https://minigames.world It’s really low budget, but the idea might be interesting to you. It’s a Laravel app that’s solely interactable through a TUI application, so Claude Code can help me operate it. To support my decision-making, I analyze collected data with Jupyter notebooks. I’ve been working on this since early October 2025.
I'm working on a command-line tool for advanced full-text search of written documents. It works in a completely different way than grep, so it can do a lot of operations that grep fundamentally cannot like proximity searching.
I called it Wosp for word-oriented search and print. I released the first functional version a few days ago: https://github.com/atrettel/wosp
https://github.com/paradise-runner/kaleidoscope
A multi-agent TUI that uses opencode and tmux to help me solve the frustrating LLM slot machine problem. I find that running 3 agents in parallel on even tough problems is enough to have one that builds what I want.
It’s also been a fun challenge to build a tool that can be used to improve itself

Experimenting with various AI models via GitHub Co-Pilot on an extremely niche project to see how far these models have progressed. Used like ~60% of the premium quota to develop the following projects:
website: https://murajah.pages.dev/
Play Store: https://play.google.com/store/apps/details?id=com.murajah.we...
Manual audio splitting tool for the above project: audio-splitter-6b3.pages.dev/
I've always been skeptical of AI-generated code. This is my first experiment with AI agents, where the full code base, implementation, debugging, and deployment are done using AI Agents MCPs.
Used VS Code all the way, i.e., all the source codes, including the code to generate the Google Play Store APK. I only reviewed the source code before committing and helped debug by suggesting ideas/algorithms.
Mostly used Claude Haiku 4.5 like 75% of the time, where it failed, switched to the sonnet 4.5 or GPT 5 codex. Interestingly, when debugging, sometimes one model struggled even after numerous iterations/feedback loops, but then the problem was solved instantly as soon as I switched to another model.
The source codes are available here:
https://github.com/wasi0013/Murajah
https://github.com/wasi0013/audio-splitter
Initially, I thought the audio splitting could be done automatically using some AI models from Hugging Face or Whisper. But the audio files have some complex repetitions; the output was miserable.
So, for now, this splitting is done manually using a Web UI (The audio splitting tool splits the large audio files into multiple small audio files, think of it like a long paragraph is split into multiple sentences.)
I will attempt again to automate this splitting task using AI, after drafting a game plan for tackling the challenges. I'm thinking of using energy drops and other similar factors to create segments.
I kinda gave up on building apps for Rocknix (since there is no easy way to distribute software) and instead have been looking at my apple watch. I ported over some software for workouts that is streamlined. I'm working on a way with MDNS to sync data to my Linux PC automatically when I'm at home.
If it works out, maybe this could be a way for me to replace the compromised Apple Music app with something that actually syncs to my music on my desktop.
I recently launched a casual math game!

A small OpenGL tutorial for Rust. Focus on understanding the OpenGL-API and interfacing with it directly, with a few as possible helper libraries.
Some of the chapters I'm currently working on can be found in the preview (https://preview.opengl.zgtm.eu/, ipv6 only).
I work on Puter (https://github.com/heyPuter/puter/); an open-source, self-hostable internet computer.
People use Puter for an incredibly wide range of things, including cloud storage, web hosting, coding, AI, and gaming. Right now, we're mostly focused on improving performance and making sure that it's as fast as a regular desktop environment!
This looks fun! But the fact that the self hosted version lacks support for some core apps is sad, I'd love to be able to build puter apps! Any plans for an app store-like ecosystem?
Yes! definitely. Please stay tuned :)
I've been obsessed with reticulum. It's a network over other networks. https://konsumer.js.org/nomadnet-js/ https://github.com/konsumer/rns-lite
The protocol is fairly simple, encrypted by default, and works over lots of interesting transports.
It's really cool, but as far as I know there's no complete C++ implementation for embedded platforms, and I still can't figure out how it actually works.
Does the gossip flooding mean every single node needs to know about every other node in the entire mesh?
I have a project vaguely inspired by this and Meshtastic that tries to make use of existing internet tech, while falling back to local links, instead of trying to replace the Internet completely.
It's very much WIP, I'm planning to get rid of all of the automatic reliable retransmit stuff and replace it with per channel end to end acknowledgment. https://github.com/EternityForest/LazyMesh#
I started working on a Arduino implementation, but it needs more testing.
It works like your address is the hash of your pubkey, and you can announce that or not.
Is there any kind of DHT like routing for the addresses? Woudn't the announces make a lot of traffic without that, if you ever got to thousands of nodes?
No DHT. it seems to work fine for 1000s of nodes without it, though. The TCP testnets, for example, are pretty highly populated.
That's pretty impressive, I wonder how it handles LoRa or Bluetooth?
I assume every packet is probably at least 32 bytes, if 1000 people send one every ten minutes, that's going to be 700 bits per second or so, right?
you should read more about it here, it's fascinating stuff: https://reticulum.network/manual/understanding.html
It works great with lora, but each interface is it's own thing. It's not exactly like meshtastic/meshcore/etc (for better or worse) but also fulfills totally different roles. You can connect 1 interface to another, and only forward messages for particular addresses, if you want, or addresses that have announced on a specific interface, and you can control what you want to propagate/route.
You can set it up tons of different ways, so just imagine this is what you want:
- 20 ESP32 lora devices around my house, that respond with sensor-data or something - a pizero connected to the internet (via a huge TCP testnet) and lora (via a SPI device connected to some GPIO.) - These are not "secret" anyone can ask a sensor for it's data. the messages are encrypted, but they are intentionally public
If any of the 20 lora devices want to to be available to talk to someone on the internet, they can, and their announcements are forwarded, so people on the testnet know the address.
I can set it up so only messages directly to those 20 devices is forwarded, but otherwise announces are recorded (and replayed) on the pi.
Additionally, I can setup propagation for just my 20 devices, so even if they are out of range or turned off, they will get the message (from the pi) when they get back in range or turn on.
In this example, the structure of the network forms a kind of tree-like thing. Each tier of the network is scaled to the amount of traffic it can deal with: pi can deal with a ton, and is connected to internet, the ESP32s only need to deal with 1-to-1 traffic (announces don't really matter to them) and only compete with traffic from 20 devices (on the same lora network.)
These messages are pretty small (an announce is ~160 bytes, message proof is ~115 bytes.) For larger messages, you string them together over a link (a 1-to-1 encrypted tunnel.) I think a key thing though, is that not every tier of the network needs to send all the same packets. For example, not even 1000th of the "testnet firehose" gets sent over the local lora net of 20 devices, based on how it's setup here.
So, the usage-flow of this would like this:
- each sensor announces on lora, pi forwards that to internet ("hey my address/pubkey is X, and I have these cool capabilities as a sensor") - a user on internet sends a data-message to the address "hey give me your sensor data" - the pi routes that from internet to lora, and propagates (replays periodically if the lora is not around) - if the esp32 has not seen that peer, it can request an announce (and the pi will forward that both ways) - the esp32 responds "oh hey internet user with X address, my sensor data is X" - the message is sent over lora to the pi, which forwards on to internet
for very small data, if you don't care about P2P encryption, you could even put the sensor-data directly in the initial announce. "hey I have this address/pubkey and the current temperature is X" since announce "app data" is great for a very small amount of data.
I'm working on https://teeming.ai, trying to solve the information asymmetry problem in the job market.
The project has been a huge learning curve for me - I started out as a skeptic of how generative AI could solve real problems (rather than just create noise) but now think that, like the internet, it can create a new kind of abundance that will be harnessable in all sorts of interesting ways.
Just launched a startup/life style business where I use AI to help people practice for upcoming interviews - https://hiredcoach.ai
Already have been told by some users that the interview prep they got from it has correctly predicted several of the actual interview questions they got, crediting its prep for their breezing through the interview rounds.
I'm really hoping it helps a lot of people!
20 years and counting, working on https://next-episode.net (it's a TV/Movies tracking website and community).
I've dedicated this week to some maintenance tasks that are long overdue (mainly modernization of the code and the database), kinda delaying the inevitable (which is to work on harder tasks in my todo - like adding features to the mobile apps).
A previewer for Sierra which is an XML based DSL for Java Swing (not by me, but by Greg Brown)
https://github.com/HTTP-RPC/Sierra
I like the ability to declare UIs and the layout manager that Sierra has is the only sane layout manager for Swing I have worked with
https://prepbook.app - minimal recipe manager
As simple to use as a notes app, with clever culinary capabilities :)
Would be great to be able to choose options for metric/imperial, fahrenheit/celcius and spoons&cups/ml&g.
Indeed this is planned to be added soon! Thanks for the feedback
I run a SVN server for my personal projects, home lab and home automation stuff.
I noticed that the SVN CLI workflow is a bit dated and I think there's room to create a graphite like experience for svn, especially focusing on stacking.
I am set out to: - create a modern CLI to interact with SVN
- create a subsystem to run alongside the svn repo (similar to gitaly)
- create a good looking web UI to browser the repo, review code reviews, etc
I'm building a node based image editing / graphic design tool called Sevro
The hope is that I can bring more procedural workflows to graphic design so you can make generative branding systems and parametric identities
(or just make sick posters)
you can try it in the browser, no login no tracking https://sevro-app.netlify.app/
I recently launched Queens Hourly puzzle on App Store.
https://apps.apple.com/us/app/queens-hourly/id6751763916
Every hour, new Queens Puzzle (LinkedIn style) is available to play. No leaderboard, no stats, nothing to buy, just pure play. Every user gets the exact same puzzle to solve for that UTC hour.
I would love to get some feedback from the community!
Created a web game: https://www.teqgame.com
I really liked the concept of games like cards against humanity, quiplash, whose line is it anyway etc. However, there was no virtual way to play it with a group of friends. Quiplash required steam setup (which was not possible on my corporate mac). So i built this as an alternate to build upon the formula.
[still in alpha phase so lots and lots of bugs]
I work on Robotics, so was recently implementing slamkit in rust. https://github.com/MostlyKIGuess/slam-rs
But a lot of what I work on is my classes giving me less time to open source nowadays, but I have also worked in implementing and mashing new Papers coming out in Robotics. Anyone who wants to talk more should please connect!
Wondering what people are using AI for and if there are public/shareable/or leaked chats out there from all platforms either chatgpt, gemini, grok, claude, perplexity etc.
So I am building this https://www.leaklake.com , where you can search your name, brand, and basically any keyword.
You can also set an Alert because crawling and starping is running 24/7.
Any feedback welcome.

I'm working on a Yelp alternative called Vibehuntr -- just something different to browse venues using Google's API, with a social layer so I can see what my friends like. It's very rough around the edges right now and it might be completely different by next week. It's been a fun experiment in vibe coding on a full stack. https://vibehuntr.io

I am currently working on a fork of Alt+Tab replacement Switcheroo to show all available windows in a tabular format. Current windows in the center. Apps with many windows on the left sorted by process name (e.g. Excel or PDF windows). Pinned windows such as open emails on the right. https://github.com/coezbek/switcheroo
Trying to relearn Rust by writing a download manager CLI. Managed to get the blocking version working, now I've implemented the async version using tokio. Have to next implement downloading chunks with different workers, and a download queue.
I've been working on a web framework in Clojure. There are already a few others, but they're, in my opinion, too focused on the Clojure community, and are much harder to sell to people I know who might otherwise use Clojure. I wanted something that was more like a Rails or a Phoenix or a Next.js. We'll see if it goes anywhere.

Polishing my dashboard for tracking profit on Solana blockchain for set of wallets: https://imgur.com/813aQsO
I want to extend it with a simple overview of most recent profitable wallets to look for new "metas" that i could profit on. This project may or may not end as open source eventually, but i currently keep it private.

I have been building music theory/midi related vst plugins in JUCE.
It's mostly targeted at me, or others that make music, but are not piano players.
There isn't much to show currently, but I have a rhythm generator, and have been working on a chord builder. The main thing that has taken time has been trying to decide which things to add to a user interface to make it worth actually building.
I'm building a tab manager extension for Chrome, that also kills duplicated tabs.
Why?
The one I used died (Manifest V2 only, and was not updated). And I wanted to test one-shot it.
Incredibly it worked!
I have found that duplicated tabs can be useful e.g. for pages where footnotes are not hyperlinked in the text. When this happens I open a duplicate tab and scroll to the bottom of the page on it.
oh, for sure, that's why the extension shows which tabs are duplicated, and I can kill the duplicates individually, but also has a kill-all-duplicates button
https://cafe.io It is a DNS service for AWS EC2 to keep the ever changing IPs when you cannot use the Elastic IP like ASG or when you don't want to install any third party clients to your instances.
It fetches the IPs regularly via AWS API and assign them to fixed subdomains.
It is pretty new :) still developing actively.
I built https://forvard.org/ with Tauri + Svelte; Forvard is a accomplishment tracker where your data lives locally (think of Obsidian but for career tracking), it has a bit of smartness to summarize your accomplishments (without sending your data over the network). I'm working on fixing bugs and adding couple of features!
I created this recently but have let it fallow in the last month. Planning to update it over the next few days / weeks. There are a crazy number of directions I could take it.
Would be great to collaborate with others on it. In particular I want to explore building the "alpha arena for AI house price prediction"
Carimbo, my 2D game engine
A FLAC encoder/decoder written in Guile scheme. I struggled to get the decoder working with most test files for a while until recently. It's more or less a fully functional decoder now. It's also 1:1 with the reference meta-flac command currently as well.

https://github.com/FarisZR/knocker
Knocker, an http knock based access service for your homelab that works at a reverse proxy or firewall level.
It's a more convenient albeit less secure alternative to VPNs like tailscale. It's more convenient because it whitelists the enite network, and it's less secure for that reason.
I'm adding an overly elaborate item and levelling up system to the adventure mode of my chess variant AI sandbox: www.chesscraft.ca
Items have a prefix and suffix system similar to Diablo 2 so I'm having nostalgic fun building it. None of this gives any advantage to the chess games you play. It's just a pointless cycle of gems, items, and experience to get more gems, items and experience. Seems fun so far.
8086 assembler in awk for retrocomputing purposes. Proof of concept worked well enough and now i'm doing an second version with more robust logic.
In the philosophy of selling shovels in a gold rush, I have built a Markdown Viewer for Mac which is optimised for AI coding with the likes of Claude.
It is simple but powerful supporting all formatting but also diagrams so you can get Claude to generate beautiful ER, or state-transition diagrams for your documentation. It also supports math notation, file links and has a cool table of contents feature
It's in the app store: ViewMD
Scratching my own (and my employer's, but they don't know that) itch and building a knowledge management system as a nerdy way of spending evenings. I refused to learn JS for years, but turns out it's not as bad as I thought, and TS makes it really nice, plus I like (to my surprise) SolidJS' JSX interpretation quite a lot. Half vibe-coded, half breaking things and learning a lot.

Got tired of every single weather app and website being littered with ads. Half the time my weather apps don't load the weather maps but the ads work fine, c'mon! So decided to start my own; here's what I have so far...once I iron out the site I'll start on the Android app.
Feedback welcome :)
Looks good!
I have a couple minor suggestions, do with it what you want:
- I'd disable the fade between two visualizations on the live weather radar, it's hard to scroll through quickly now.
- Personally I'm always looking for the hourly and daily forecasts. Currently they are split by the live radar. I'd either move them all above or all below the radar if you want to keep this format

I'm working on a free replacement to the NY Times daily mini crossword after they started charging for it and I didn't want to pay. https://www.jepeto-mini.com/ (DNS may still be propagating).
A fun project with lots of challenges finding word lists, refining them, using AI for clue generation, etc.
I played it, and it was fun. Some feedback (I'm on mobile) is that it needs UX improvement.
At first I wasn't sure what I had to do, it simply throws you into the game, and it's easy to get confused with the numbers around it, because usually if there are numbers, there is going to be somewhere (usually at the bottom) the numbers and the clue for each of them.
It took me a bit to find how to get the clues from the vertical words (double tapping).
The onscreen keyboard isn't very responsive in the sense that I had to tap several times the backspace to delete a letter.
It doesn't allow to play again :(
Thanks for the helpful feedback. I'll take a look. Yes, you can only play once per day.
Working on some tailored to my needs tax reporting software. I submit claims to my workplace in batches under a number of different categories. Using this as an excuse to get better at some bits of SQL, leaning Textual as well, which I'm hoping to use in other things. Other than that I'm cooking a few IRC bots that I swap to when the other code becomes a bit too boring

I'm working on Sum Buddy an AI spreadsheet. I didn't like the way Microsoft and Google were integrating their AI by essentially tacking on a chatbox and I wanted to explore more native integrations, like its another part of the tool bar.
I am trying to build a local setup where I spawn dockers (fetched via skopeo) as systemd-nspawn machines in userland (rootless), with network managed by a service that uses netkit devices to setup network in their empty network namespaces. I am looking at using Sommelier to manage wayland.
The end goal is to have a laptop with an easy way to build lab environments which is secure and rootless.

I’ve been working on an idea wishpool.
Anyone can post an idea for something they wish existed — an app, a game, a tool, or anything else — and share it. When more people back an idea, it gains momentum and starts getting built, either by AI or by community makers. The goal is to turn crowd energy into real progress.
I'm building a scraper in Golang based on Colly to do two things:

I would love feedback and of course any bug reports. :)
Simple feedback collector. Something I end up building in every project, so why not built it once and productise even just for myself. Still building out the dashboard, some clustering, and automated PRs (by Claude Code)
Great idea!

I’ve gone old school. After reviewing a few people’s CV’s the easiest format was for me to record a video with the feedback, so I put a site together for that:
No AI, you just buy my time.
I’m also looking to do a couple freebies if anyone wants to anonymise their CV and let me use it for a promo example.
I like the path options.
Is this US focused or also applicable to UK/EU people?
Thanks. I’m based in the UK so have a good grasp on that, but I’ve reviewed someone’s resume from the US just as easily. Generally, English speaking and preferably in a digital related field, but a lot of the common pain points seem to be universal. It’s only difficult when it’s a field that’s highly niche as hard to know what’s common knowledge.
I like to play the role of the person doing the hiring, hence why the form asks for an example job description.
Interesting, the impression I got from the site was that this is US specific (dollar currency) and not that you're based in the UK.
I'll keep your site in mind if needed, I think the video response is a key selling point, great idea.
Thanks, and great feedback about the use of dollars!
I’m building Cozy Watch, a macOS app that brings GitHub notifications straight to your desktop.
It tracks pull requests, CI results, and mentions in real time — so you know when you’re needed without checking GitHub or digging through emails.
It has a menu bar for quick access and a clean desktop UI for more detail.
Hey there, love the app. Is there a way to configure Cozy Watch to use a PAT instead of OAuth?
Some years ago, I co-founded a startup that would run workflows when email messages arrived, any email from any source was parsed and it would trigger "actions" that could include notifications - this sounds like a good use case for it! You don't need the service to expose an api to listen in, since most services end up sending email as last fallback.
Thank you for you feedback!
Do you still run that startup?
With Cozy Watch, I use the GitHub API, never thought about using emails as triggers.
I’ve actually got GitHub emails disabled, they can get pretty spammy.
Sadly no, the feedback loop with users lacked consistency and we never got around finding use cases. One of the visions for it was to help people clean up inboxes, because as you put it, some sources can get pretty spammy. I'll keep an eye out for Cozy Watch, I hope you are successful!
Thank you!
Please let me know if it can be helpful for you or your team.

A multiplayer game prototype, written in Rust, using Bevy + egui for graphics. Think of it as a bare bones implementation of a game like Runescape, mostly to test out current LLM capability.
I haven't found much value in LLMs for coding beyond very self contained tasks, but some people speak highly of it, and I want to be sure that I'm not missing out. So from time to time I give new tools a try. This time is "Claude Code on the web".
I've put in an estimated 50 hours so far. It has a client and an authoritative server. The client displays 3D graphics with some placeholder models. From the client, you can click on tiles and move to them, or click on enemies to pathfind and attack them. You can right-click on tiles or monsters to open a menu with options (attack, trade, move). There are some unit tests and a few integration tests.
Right now the issues that Claude has been unable to resolve after a few attempts are: * Attack animations. I'm trying to get it to raise and then lower a rectangular block to simulate a sword attack. It really doesn't get it, and it's harder to write tests for compared to movement and server-client networking. * "Entity interpolation". Rather walking entities instantly moving from tile to tile, movement should flow smoothly.
I have Claude Pro ($20/mo) which let me make a few commits per day. After a few days of that, Anthropic offered $250 in credits to promote "Claude Code on the web". The credits expire after two weeks. I'm now five days into that period and have gone through $50 in credits. It is heavily rate limited and frequently locks me out for multiple hours after only a few interactions, but it's free credits so I can't really complain.
I work on Harbor (https://github.com/av/harbor), it is a project to save hours when setting up LLMs locally.
I pre-integrated over 50 different LLM-related projects, added a nice CLI and a Desktop app on top to manage the configs.
I'm working on my own code review app powered by local or self hosted LLMs. It started as a way to lint my own code and took off from there. It's basically like greptile or co-pilot, but has some things that they don't:

I'm working on a boardgame with the help of AI. It's way too easy to create placeholder art with an n8n pipeline, but GPT-5 regularly fails at writing and debugging LaTeX which I'm using for all of the card creation.
Specifically, TikZ is often outside the ability of GPT5 to successfully write or debug.
Working on IT Asset Management & Endpoint Security, Automated platform for IT teams dealing with asset sprawl and security compliance.
Check it out: https://zecurit.com
Would love feedback from anyone dealing with endpoint security or compliance challenges..
Very interested in this type of thing. I can't see anywhere where pricing is mentioned, even ranges would be a useful benchmark to know if it's something within budget.
Love the script hub, very cool idea.
Thanks! You can check out our pricing here: https://zecurit.com/pricing/
We’re also building a script repository so you can run scripts directly on agents from the Zecurit console.

Building a set of experiments that explores LLMs visual understanding of your photos to learn about you, especially given the recent learnings from deepseek-OCR. Part of the experiments delve into storing the memories with GraphRAG so they can be effectively retrieved without losing too information.
Building a language learning tool again[1].
I have found for myself that there is a lack of vocabulary learning apps that have good search functions. When I make a search function, I want it to be able to find all subsets of words, that I could think of. Instead what many search functions only allow you to do is, to first find one set of words, and then in a new separate search find another set of words. Currently working on that search function.
Also what I find annoying in spaced repetition learning apps I have seen so far is, that they will ask you very simple words over and over again, just because you didn't see them in a while. But I really don't need to learn those words over and over again, because I just know them.
Another annoying thing is, that in some apps you cannot see your learning progress. How many percent you already learned. Or that you cannot specify how difficult a word is to learn. Or how relevant it is. All this metadata, that could be good for learners to be able to search through, when searching for the subset of words they want to learn next. Oh, and of course tags ... With tags one can add all kinds of attributes to words. Maybe I am only looking for nouns or verbs. Maybe I am only interested in words that have something to do with family.
There is still a lot to do, but it is taking shape nicely.
The app is written in Python and tkinter. It is very simple to use in most aspects, and I really don't care much about the looks. I actually find them refreshingly simple and functional. Not this "everything flat" kind of epidemic in UI, and widgets still give feedback when using them. Not web based with the typical nodejs or npm overhead and tens or hundreds of dependencies. Nope, keeping it very minimal so far.
I also have another idea, that might give it a modern touch, but that might also introduce overhead and probably should be an optional setup or feature: Give users tools to let LLMs generate example usages of words, if they want to do so. Of course that would have to be a local LLM I don't want to get into users having to sign up somewhere and get API keys and all that.
I am also not planning to make a mobile app. Maybe later I can create an API, so that one could build a web frontend, if one chooses to do so. But first I want to build this app and the functionality behind it.

Probably only building for myself here but super fun to explore how that would look like.
This is good - I previously used Buffalo https://gobuffalo.io/ at my startup, but eventually decided to move off it. Go doesn't seem like the kind of language that could support a framework like rails (it's safety takes away from the flexibility).
Would love to see how this turns out though! Great work
Thanks!
Yeah I tried out Buffalo as well but felt like they ended up doing too much!
If you check it out, I'd love to hear what you think! It's not ready for a v1 yet, still very exploratory.

I'm building Envelope — a banking product purpose-built for envelope-style budgeting.
Most “budgeting banks” (Ally Buckets, Wells Fargo Budget Watch, etc.) bolt budgeting on after the fact. Envelope was designed from day one as an integrated budgeting bank account. The checking, savings, and debit cards are all built around real-time envelope balances.
Each envelope acts like a dedicated account with its own balance and optional virtual card. Spending directly from an envelope means your budget is always accurate — no syncing, no spreadsheets, no “catch-up” categorization. Everything runs on-ledger with automatic spend-locking and instant visibility.

1. Langsam - https://github.com/cellux/langsam
This is an AST-walking interpreter for my personal LISP dialect written in C. Once it's ready, I would use it to implement a low-level, statically typed language (Schnell) as a Langsam library. The goal is to gain the ability to JIT-compile Schnell code (sexps of a statically typed language) from Langsam. Once this works, I would rewrite Langsam in Schnell so that it becomes a fast bytecode interpreter. With the faster Langsam (and the Schnell built into it) I could build a little OS called "Oben". The OS would first run on top of Linux, then I would attempt to bootstrap the entire stack on bare-metal. I already have a Forth dialect implemented in assembly language (Grund/Boden). The idea is to implement Langsam in Grund and then bootstrap the entire Grund -> Langsam -> Schnell -> Oben chain on something like the qemu q35, later on a Raspberry Pi Zero 2W and maybe even my own hardware (ie. an FPGA board like what Wirth et al. created for Project Oberon).
2. MTrak - https://github.com/cellux/mtrak
This is a TUI MIDI tracker written in Go. Not too user-friendly: one has to enter raw MIDI messages in hex into the tracks. Can be connected to synths like Fluidsynth or Surge XT via JACK MIDI. Unfortunately it takes a lot of CPU time, probably due to the use of BubbleTea (and no time spent on optimization).
3. Mixtape - https://github.com/cellux/mixtape
Beginnings of a programmable, non-realtime audio sample generator/manipulator written in Go with an OpenGL GUI. I was thinking about how people in the old times cut up the magnetic tape which contained the sound bites and rearranged them to build something new. What if I'd implement a data type called "tape" which is basically a piece of sound and then provide operators in a Forth-like language to create and manipulate such tapes. Each tape could be a sound and then these could be stitched together to form songs. Who knows maybe an entire song could be represented as a hierarchy of these tapes. Each sound or song section could be its own file (*.tape), these could be loaded from each other, maybe even caching the WAV generated from the code of a tape to speed things up when there is a huge hierarchy of tapes in a project. Lots of interesting ideas are brewing in this one.

I have two side projects I continue to make some headway on: a practice call platform (practicecallai.com) and an iOS baby tracker / newborn app (https://apps.apple.com/us/app/lil-baby-tracker-newborn-log/i...).
The last month has had its ups and downs.
Ups = some local-area doulas have started sharing the baby app in a big WhatsApp group & growth is starting to pick up.
Downs = my first vibe-coding horror story. For PracticeCallAI, the subscription flow was failing and somehow outside my test coverage, so I've been missing out on new subscribers for the last two months. In an effort fix it, Replit Agent - which I have been loving otherwise - truncated the table that stores all of the user calls. and their database rollback is throwing errors. So that's been fun.

How does this work? Good old scraping/parsing html or you feed the html to a LLM and let it parse?
Nice idea btw!
Something like that - parsing and scraping have come a long way right? Plenty of different ways that are available. The adoption of various LLMs have given more options definitely. We use both traditional and LLM methods.

systemg - "Systemd, for busy people".
https://github.com/ra0x3/systemg
I'm personally tired of getting stuck in config/deployment hell every time I want to deploy a long-lived web service. Sure I eventually learned how to use systemd, but systemd has SO many things baked into that I simply don't need. systemg is a lightweight process supervisor that features everything you'd typically want when running/managing production web services in the wild.
Would love feedback.
I love that it's Rust based, but being busy is exactly why I like Systemd, it Just Works, as long as you don't need to customize the OS at all.
True, but I think the point I'm trying to make is that when it comes to deploying (what are more often than not) web services, getting to the point with systemd where it "just works" requires more pain than I'd like - especially with regard to production deployments (reading logs, checking service status, wondering why my env vars aren't being read, etc).
If at the time when I was cutting my teeth on systemd, I had access to something more lightweight and "do one thing well", I think I would've gotten a lot more sleep :)

https://www.athilio.com/ Currently finishing up garmin integration and a mobile port of the app. The app is aimed at people with goals related to their wellness or sports / training. Somewhat similar to training peaks but more focused on integrating different metrics, like sleep and readiness from oura and training data from garmin. Also user has more control. 0 focus on social features. Pricing aims to be affordable (1/4 - 1/2th of similar services), this is hopefully possible with local first approach for the data(sqlite). Saves tons of money on the backend costs when only the syncing from integrations + oauth is on the backend and no storage. Also I think this is more friendly for the users privacy and I would prefer to not store the users datas on my servers for GDPR reasons. Syncing between user devices can be done similarly as Obsidian with icloud. The user experience is a bit influenced by software observability.
Professionally, my team just made our big new launch of a feedback collection tool - https://www.sunbeam.cx/asklet. It tries to go just a little beyond the "give us a star rating" and collect some more detailed feedback without being too in-your-face or annoying.
In my spare time I've been working on a small service for making sure I remember friends and families birthdays. I think it's really important but with friends all having kids it's becoming more and more to keep track of in the calendar. I'm putting together a small web app which takes in the birthday and sends me a reminder a set amount of time away, with some suggestions for birthday gifts.
The suggestions right now are just ones that I've entered as I've come across ideas throughout the year for people. But I want to try and plug in known interests and see if I can do a better recommendation for myself. I'm hoping to keep it quite small as I don't want to take the spirit out of remembering people's birthdays, but I do want to be more consistent.

I am working on yet another news aggregator: newsmuncher.com
So far i've got the scraping and embeddings / similarity clustering down (to build timelines of news stories), lots of data cleaning and UI refinement required. I find it hard to make choices, maybe I need a cofounder who can pair up with me. Looking to either monetize news data or build a news analysis / intelligence platform.
May I ask what techniques either you're using or would recommend for similarity clustering? I looked into topic modeling, but it seemed a long way off from reliably bundling together stories like on Techmeme.
(I'm working on basic blog and video aggregators like Planet Python.)
For similarity it is important to consider the dimensionality of your embeddings. The larger the text you wish to compare the bigger each embedding should be (to my limited understanding).
So a paragraph might be good as a 384-dim vector but if you have 1,000 words then you might want a 768-dim embedding (if not higher). Embedding models have slightly better/worse accuracy based on the training data they're fed, but higher dimensionality definitely gives better results - to a great extent. If you have an extensively long piece of text, it's easier to chunk it into pieces and create separate embeddings. You do have to manually stitch them back together and do some cleanup when displaying results but it works.
Once you have embeddings for all your data the rest is just cosine similarity, play around with the min_similarity. You will need to build good indexes on postgres but it is basically all you need.

Another month another project inbound.
https://flopper.io - this has become a big focus. It's essentially a table for flops. Calculator coming soon for flops and power. Imported >600 Datacenters in October.
https://llmstxt.studio - models need data and I believe llms.txt as an idea has merit. Likely needs an authority. Will add more audit tools to give people any slight benefit they can have for SEO.
https://probe.bike - tell stories with your bikepacking data.
It's pretty hard to work on all these ideas and areas whilst working. Feeling a bit over stretched.
Flopper remains the main focus as release cycles are slow and it overlaps with work slightly.

I’ve recently written ImapGoose, a daemon which keeps a remote IMAP mailbox in sync with a local tree of Maildir: https://whynothugo.nl/tags/imapgoose/
It relies on “modern” (2009) extensions to minimise traffic and avoids polling entirely (relying on the server to notify of new messages or changes as they happen).
It’s currently quite stable. The only known issue is that it can take a while to detect a timeout when the system is suspended and woken up again (there’s no portable API to detect suspend/resume).
Since then, I’ve been working on a simple TUI email client based on notmuch and maildir. So far it works really well for processing email, but lacks any capabilities for handling attachments, composing, sending (these are obviously on the roadmap).
Oh I'm super curious about your notmuch project. I've been wanting an email client that's just a tui on top of notmuch. Wonder if we can pair up? Ill ping you over email

I’m building a small live NFL game-prediction tracker and writing up what I learn as I go:
https://michellepellon.com/portfolio/nfl-game-predictions
# What’s under the hood today
ELO translated to the NFL with margin-of-victory adjustments, a modest home-field term, and week-to-week recency weighting.
Post-hoc calibration with isotonic regression so 70% predictions land near 0.70 empirically.
Monte Carlo to roll games forward for distributions on weekly win odds and season outcomes, plus basic reliability/Brier/log-loss tracking.
# Where I’m taking it (ensemble ideas)
Blend a few complementary signals: (1) pure ELO strength; (2) schedule-adjusted EPA/Success Rate features; (3) injury/QB continuity and rest/travel effects; (4) a small “market prior” from closing lines; (5) weather/play style pace features.
Combine via a simple stacked model (regularized logistic, isotonic on top), or a Bayesian hierarchical model that lets team effects evolve with partial pooling.
Separate models for win prob vs. expected margin, then reconcile with a consistent link so the two don’t disagree.
Emphasis on calibration over leaderboard-chasing: reliability diagrams, ECE, PIT histograms, and backtests that penalize regime drift.
# Why I’m doing it
It’s a sandbox to teach myself Monte Carlo and ELO end-to-end—data ingest → feature plumbing → simulation → calibration → eval—on a domain with immediate feedback every week.
# How this connects to my day job (healthcare ops)
I work at BlueSprig, running ~150 ABA therapy clinics. I’m exploring whether ELO-like ideas can augment ops decisions:
“Strength” ratings for clinics, care teams, or scheduling templates based on outcome deltas and throughput (margin-of-victory ≈ effect size/efficiency).
Opponent/schedule ≈ case-mix, payer mix, staffing constraints, geography.
Monte Carlo for expansion planning (new-site ramp curves), capacity/OT forecasting, and risk-adjusted outcome monitoring with calibration so probabilities mean something.
Guardrails for fairness and interpretability so ratings don’t become blunt scorecards.
# Help
If you’ve shipped calibrated ensembles in sports or have pointers on applying rating systems to multi-site healthcare operations, I’d love to trade notes or if you need someone to this and other kind of work for their dayjob email me at mgracepellon@gmail.com -- I would love to do this fulltime.

Hi All,
My Name is Will, I am a final year college student in Milan and the Co-Founder of this project Neutralis. I came across this website super randomly this evening and am fascinated!
I will preface by stating that I am not a programmer nor an AI/ML engineer, just a an economics student with an amazing team of people around me.
This is our first project and for the past year we have meandered through the tests and trial and error required to learn and understand what we need to build but as I’m sure you all know every task is linked to an exponentially increasing number of problems needed to be studied and solved as we trudge towards the market. Since I believe we’re all in the same boat and there are like minded and far more talented people on this page, I wanted to share what were doing and shout into the void to see if we can maybe find some answers to what were looking for!
The project is this, an Intelligent fault detection diagnostics system tailored for industrial scale Heat Pump systems. If you have no bloody idea what that is don’t worry! It’s basically the standard boiler’s successor as an electrical thermal supply system which (at least in the EU) will be replacing all pre-existing systems in the coming years due to legislative changes.
The ecosystem of our product is a model of some format (question to follow) paired with a sensor suite which will be connected to an “OS” for technicians and maintainers with the goal of optimising their post-installation workflow processes.
The software is not obscure, only a little complex w.r.t double format databasing and the presence of multiple user types within an org, but this with time can be organised. The difficulty lies in the model. These systems have datapoints in the 6-7 figures and hundreds of components each requiring enough inference to be able to (with a justifiable accuracy) perform the inference required to pinpoint diagnostics, also including the multitude of ambient/external factors affecting physical systems in real time. This complexity has meant that our ML lead who is finishing his PhD is left scratching his head about what the best approach would be.
Since we would like to have a modular system to allow for any scale our first thoughts lean towards Reinforcement learning. We have a partnership in industry that is allowing us to secure vast stress test datasets from manufacturers of these systems which display the full range of results produced from these systems, but these are only from the Heat pump alone. Therefore, we are also working on gaining access to as many pilot sites as possible to collect data on entire systems so that we can cover all bases. The issue with this is that the time required to have a model viable for launch we fear would be too long and our runway is short.
Option 2 is a digital-twin. If we are able to produce a platform capable enough to align its simulations closely enough to the data collected from the sites, then only a fault library in a relational DB is required to get the desired outcome. However, as specified, to create a modular digital-twin which has internalised all of the external/ambient factors into its computing seems almost impossible. We have been simulating on one produced in Sweden, it doesn’t even come close.
Finally, we have thought instead to look into finding a highly specialised LLM which we could refine well enough to match our use case, for which our understanding is really primitive as we don’t have an AI specialist but the intuition is, produce a technician who is as experienced as humanly possible and so with just a look at the data is able to give you a step by step solution and fix guide.
What do you guys think the best course of action would be?

Working on UPSS (Universal Prompt Security Standard) - an open-source framework for managing LLM prompts securely at scale.
The problem: Most organizations hardcode prompts directly into application code, creating security vulnerabilities (90% prompt injection success rate in typical deployments), operational inefficiency (3-5 day deployment cycles for simple prompt changes), and compliance gaps (insufficient audit trails for SOC 2, ISO 27001).
Our approach: - Externalize prompts from code with secure configuration management - Implement modular middleware architecture with composable security primitives (BasicSanitizer, LightweightAuditor, SimpleRBAC, InputValidator) - Provide complete audit trails and version control with approval workflows - Support both startups and enterprises with practical, not theoretical, security
Version 1.1.0 is now available with Python implementation and examples for Node.js, Java, Go, Rust.
We're actively looking for community contributions - security primitives, framework integrations, language implementations, and adoption stories.
