| YesBox 3 months ago | next [–] I changed gears and moved into the video games industry at the end of 2021.I started developing a city builder called Metropolis 1998 [1], but wanted to take the genre in new directions, building on top of what modern games have to offer:- Watch what's happening inside buildings and design your own (optional)- Change demand to a per-business level- Bring the pixel art 3D render aesthetic back from the dead (e.g RollerCoaster Tycoon) [2]I just updated my Steam page with some recent snapshots from my game. Im really happy with how the game is turning out![1] https://store.steampowered.com/app/2287430/Metropolis_1998/[2] The art in my game is hand drawn though

| iknowstuff 3 months ago | parent | next [–] So pretty. But:> Both adults in a family will now own a car. This is required since there are not other transportation options, and sidewalks are optional.Is this temporary or are you planning to release it like this? SimCity leaned into euclidean zoning (separate industrial/residential/commercial zones) and pocketable cars which needed no parking, and thus failed to properly showcase how ugly car-centric cities actually are. I’m sure they did it because it made for an easy gameplay loop/balancing but I’d hope we could come up with more realistic and interesting mechanics in 2026

| sersi 3 months ago | root | parent | next [–] I actually would really love that in a city planner. A game that actually simulates walkable cities versus car centric abominations and would adapt families strategies based on the availability of sidewalks, public transports and incentives.

| YesBox 3 months ago | root | parent | prev | next [–] The limited transportation options is temporary (the game is launching into early access).Both adults owning a car will be dynamic/based on the city once there are more transportation options.I'll also be adding options so the player can control how difficult traffic management is.

| titanomachy 3 months ago | root | parent | prev | next [–] Did you ever play cities: skylines? Keeping traffic manageable was a big part of the gameplay. Without good transit the roads would all gridlock regardless of how many lanes you add to the highways.

| iknowstuff 3 months ago | root | parent | next [–] Played it a ton! But they stuck with euclidean zoning from SimCity and most car trips in CS don't need parking - they just disappear if there's not enough surface parking for them. They also poof away when stuck in traffic too long (unless modded).

| smusamashah 3 months ago | parent | prev | next [–] I have been following you on twitter since I saw it. It looks amazing. Recently tried the demo. It is like under 50MB (the demo at least) which is insane these days. Placing building required construction of the building room by room which was tedious. I am sure some people will enjoy that. Will that be the core part of final game?

| YesBox 3 months ago | root | parent | next [–] Thanks! Designing your own buildings is optional. The game has a feature to place zones where buildings automatically grow, but will be limited to residential and office zones at early access launch.

| zelphirkalt 3 months ago | parent | prev | next [–] Can you tell more about your background? Making a sim like this also crossed my mind many times, but I learned in the past, that without much of any art skills, I would have to use resources of others or hire someone to make the graphics and so on. In the times of me playing around with RPG maker it was the missing story that was the problem. So it seems often that one core aspect is missing, when wanting to make a game. How did you learn to fill that gap, learn how to get that skilled with making the graphics?

| YesBox 3 months ago | root | parent | next [–] My career background is software, but I've been a creative person my whole life.Ive hired out help for the pixel art, and then I enhance everything with shaders (tech art).If you're gonna make a game as an indie, you need to figure out ways to fill in your skill gaps. The competition is brutal. If you can't do it/dont have time to learn and do it, then the only other option is to hire out.orA lot of studios are formed from people (cofounders) who depart larger studios, so if you really want to get into the industry, you could start there and network.

| tarokun-io 3 months ago | parent | prev | next [–] Metropolis 1998 looks beautiful! (and addictive!)Will you do a native Linux release, or has it been tested with Proton?Also, just from watching the video and screenshots in the Steam page, it seems like a crazy amount of work. Are you doing everything by yourself?

| YesBox 3 months ago | root | parent | next [–] Thanks :)I'll be looking into porting during early access. I've heard the game runs on Linux with a compatibility layer though.I do everything except the pixel art and buildings. It is a crazy amount of work!

| yreg 3 months ago | parent | prev | next [–] We really do need more new isometric grid based games. They are less realistic but it is so satisfying to build in them.I've commented on it before: https://news.ycombinator.com/item?id=39810716

| nanders 3 months ago | parent | prev | next [–] I am one of those who grew up with Sim City/Transport Tycoon. I will definitely try this when it's released and go back into nostalgia but with a modern touch. Adding it to my wishlist right now. Good luck with wrapping this up towards a release!

| 2muchclout 3 months ago | parent | prev | next [–] This looks awesome! From the isometric perspective, how did you do the walls or vertical stuff in general? I have done a few game like that and always find it to be a struggle in 2D.

| YesBox 3 months ago | root | parent | next [–] Thanks! The vertical axis is also broken down into a grid in a sense. Each "cell" is placed in a specific floor as far as the engine is concerned.So like (C++):

vector>

Each vector element is a floor. You just need to move the sprite up in screen space to position it.Though I wish I went with a vector>> approach now a days , ,

| _el3m3n7 3 months ago | parent | prev | next [–] Love the concept! I would love it even more if you could add support for SteamDeck/proton

| herpdyderp 3 months ago | parent | prev | next [–] I came across your game last year! Can't remember how. Any hopes of macOS support?

| YesBox 3 months ago | root | parent | next [–] Not at launch, but I'll be looking into porting during early access! Everything in the game is cross-platform ready

| zimpenfish 3 months ago | root | parent | next [–] I'll throw a third (fourth, fifth because I know a couple of people who'd play this on Mac but who have no access to Linux or Windows) request for a Mac version on the pile.

| wjr 3 months ago | root | parent | next [–] +1 for request for Mac

| pjc50 3 months ago | parent | prev | next [–] The aesthetic is so incredibly 1998. Reminds me not just of SimCity 2000 but the lesser played "A-Train", with its gentle day-night cycle.

| nickzelei 3 months ago | parent | prev | next [–] Awesome! I’ve had this game on my wishlist for a while now. Just saw there is a demo, will have to check it out!!

| badpun 3 months ago | parent | prev | next [–] I get a lot of "UFO: Enemy Unknown" vibe from the art.

| zorked 3 months ago | parent | prev | next [–] I only had to look at the first screenshot to think "yup, this was made for me, I am buying this".

| Folcon 3 months ago | parent | prev | next [–] Awesome to see your progress YesBox!Didn't realise you'd swapped to isometric, it's looking fabulous!

| YesBox 3 months ago | root | parent | next [–] Thank you! Really appreciate it :)

| tr3ntg 3 months ago | parent | prev | next [–] Logged in to agree with all the other comments: this is so, so pretty. Will try the demo soon.

| 999900000999 3 months ago | parent | prev | next [–] Very very cool!Did you roll your own engine, I know Godot has issues scaling past a certain number of simulations.

| YesBox 3 months ago | root | parent | next [–] Thanks! Yes, I created my own engine to maximize efficiency (where needed). I think it was the right choice for me.

| holografix 3 months ago | parent | prev | next [–] Looking forward to the release!

| gunju84 3 months ago | parent | prev | next [–] Curious, What u used to do earlier ? before changing gears?

| jmole 3 months ago | parent | prev | next [–] Any chance you'll release on macOS/Linux?

| cdaringe 3 months ago | parent | prev | next [–] Killer latte art

| asimovDev 3 months ago | parent | prev | next [–] The visuals are stunning, great work!

| adamgoodapp 3 months ago | parent | prev | next [–] Looks amazing, added to my wish list!

| Aeolun 3 months ago | parent | prev | next [–] Cool! Isometric for the win :)

| vijaym2k6 3 months ago | parent | prev | next [–] Damn, that looks nice!

| multisport 3 months ago | parent | prev | next [–] Looks very good!

| vldszn 3 months ago | parent | prev | next [–] Looks amazing!

| strontian 3 months ago | parent | prev | next [–] wow, love the look of your game!

| nickandbro 3 months ago | parent | prev | next [–] very cool

| keithnz 3 months ago | prev | next [–] Vibe-coded a YouTrack CLI tool in < 1 hour:https://github.com/keithn/ytAlso working on a language for embedded bare-metal devices with built-in cooperative multitasking.A lot of embedded projects introduce an RTOS and then end up inheriting the complexity that comes with it. The idea here is to keep the mental model simple: every [] block runs independently and automatically yields after each logical line of code.There is also an event/messaging system:- Blocks can be triggered by events: [>event params ...]- Blocks can wait for events internally- Events can also be injected from interruptsThis makes it easy to model embedded systems as independent state machines while still monitoring device state.Right now it’s mostly an interpreter written in Rust, but it can also emit C code. I’m still experimenting with syntax.Example:

module WaterTank { type Direction = UP|DOWN let direction = UP let current = 0

[>open_valve direction |> direction] [>update level |> current]

[ for 0..30 |> iteration { when direction { UP -> !update level=current + 1 |> min(100) DOWN -> !update level=current - 1 |> max(0) } ~ %'{iteration} {current}' } ]

[>update level |> when { 0..10 -> %'shallow' 11..15 -> %'good' 16.. -> %'too much!' then !open_valve direction=DOWN } ] }

| vintagedave 3 months ago | parent | next [–]

automatically yields after each logical line of codeI've become more and more interested in code that yields (coroutines etc, read this fascinating article on HN just a couple of days ago: https://willhbr.net/2026/03/02/async-inject-and-effects/ )Can you share more about this? How the async model works? Why it does -- is it a performance guarantee given the RTOS comment? Or is it more about the state machine idea, and how or why does yielding every line (not, say, every state transition, though I have no idea if or why that would be more useful) relate to that?I mostly just have lots of questions because it sounds fascinating, so if you're looking for an excuse to talk about it, please count this as that excuse!

| keithnz 3 months ago | root | parent | next [–] The idea is not so much any kind of hard real time guarantee (in practice it switches quickly so it is soft realtime) but what you often have when doing bare-metal embedded systems is a lot of parallel state machines, not necessarily because the state machine is the best mechanism it's more because you want things to happen in parallel in C/C++, this can be annoying to deal with so you end up with these statemachines that don't block, you cycle through them, and you get "parallel" operation, but anything can block other statemachines, and things like long running for loops need to be broken into non blocking states. I've often thought an Actor Model like thing would be really nice if baked into the language and that the actors were all "live" such that were all processing in parallel and firing off events as needed which is how I started this. I initially was thinking switching on something like state transitions / explicit yields but every statement yielding automatically lets you run multiple "forever" loops which in turn might have long running for loops (like updating a display) statement switching means you don't have to worry about when to yield. Instead I reversed it and figured it would be nicer to define things that need to run as an atomic operation as that seems to be less frequent. This way you generally don't need to worry about blocking and it feels like it's programming as if it was pre-emptive multitasking. Multiple little programs all concurrently running and firing off events to communicate with each other

| keithnz 3 months ago | parent | prev | next [5 more] holy, downvotes on what I'm working on?

| benterix 3 months ago | root | parent | next [–] You said "vibecoded", maybe it triggered someone. I upvoted you as I just learned YouTrack exists, and it has 10-users free plan, I'm going to give it a try,

| keithnz 3 months ago | root | parent | next [–] YouTrack is pretty good in that is easy to plan and manage work across multiple projects. Jetbrains made it years ago when they got frustrated with Jira for managing their projects. For most of their products (IntelliJ, Ride, Webstorm, Datagrip, etc) if you want to raise a bug you raise it in their YouTrack. It is super customizable and has a reasonable API. Only thing I find is their website is a bit sluggish. The API is pretty quick though, so the CLI tool is reasonably snappy.

| tomwojcik 3 months ago | prev | next [–] Since subreddits related to identifying AI images/videos got very popular, my wife started to send me cute AI generated videos, older family members can't distinguish AI videos at all, I've decided to code a weekend side project to train their Spidey sense for AI content.https://IsThisAI.lolThe content is hand picked from tiktok, Instagram, Facebook, Reddit and other AI generating platforms.Honestly I don't know where I'm going with this, but I felt the urge to create it, so here it is.I learned how to optimize serving assets on CloudFlare.Feedback welcome.

| wonger_ 3 months ago | parent | next [–] +1 for training parents' tech literacy.I dunno if/how this could be taught, but I feel like half the battle is critical thinking with an adversarial mindset towards media -- who would make this, why would they want to show me, do I see anything that makes this impossible, is it worth engaging with in the first place, can I fact check this.

| tomwojcik 3 months ago | root | parent | next [–] Yep, my thoughts exactly. But the consumer rarely thinks critically when looking at ads, not to mention regular social media posts and the Big Corp has no money in proving what assets are AI generated.I'm trying to gamify the training to make the experience more appealing.I store a "proof URL" on the backend, but I don't know if it makes sense to serve it to the end user. Also, a Reddit discussion is not necessarily a proof one wants. A fingerprint would be better, but not all images are generated with Google. That's another problem to be solved.

| Melatonic 3 months ago | parent | prev | next [–] Great idea - are you sure however that all of the "AI Generated" examples are actually AI? What about stuff made by good old fashion human + photoshop ? Obviously this would still be "generated" or not real but I think it is a somewhat important distinction

| zelphirkalt 3 months ago | parent | prev | next [–] Tricky! I often also guess wrong. But I noticed it has some bug. Sometimes I can click either option "AI Generated" or "Real" and nothing happens. Even if I click 10 times, still nothing happens. The buttons must have some broken event handling or something.EDIT: Hm, I switched tab, away to write this comment, now that I switched back, it showed me that I clicked correctly. So it seems, that sometimes it just has huge delay in accepting my choice?

| tomwojcik 3 months ago | root | parent | next [–] The project got some traction, over 5k requests since I posted this. Probably the DB state needs to be optimized a bit. Thank you for reporting! I really appreciate itEdit: I don't see slow traces in Sentry. No idea what caused this. Also, voting goes through redis and the dB load is low. Weird. I probably have to add gunicorn workers.Edit2: Bumped gunicorn workers from 2 to 4. Should be fine now, under the current load. Again, thank you for reporting!

| jayteedee 3 months ago | parent | prev | next [–] I love this. Each time my parents need their wifi fixed I'm going to make them do 5 of this app before it get to work.

| tomwojcik 3 months ago | root | parent | next [–] Thank you for the kind words. I don't expect it to spread like fire, but I'd appreciate if you could share it with your folks. I don't intend to monetize it, my goal is to have some small daily traffic.It's SFW and localized to the most popular languages.

| jayteedee 3 months ago | root | parent | next [–] Update. I didn't expect my parents to enjoy playing the game. Apparently, they are aware that they are falling for AI videos and don't like it. And there are a lot of entertaining videos to keep them engaged and easy to spot "give me's" to keep the frustration level down.

| monkaiju 3 months ago | parent | prev | next [–] What does the "this one is controversial" label mean? Does it just mean the voters are split or does it mean its not known whether or not the image/video is actually AI-generated?

| wastewastewaste 3 months ago | parent | prev | next [–] I somewhat like it for what it is, but expected something else based on description. This is just a real/ai guesser that doesn't really train you at all.

| edarchis 3 months ago | root | parent | next [–] I think that it's a great opportunity to play with relatives. Each person can explain why/why not and that's probably the main point.It'll also probably shut the mouth of those who think that they know better. This works with the driving license. Start a test with the whole family and watch the older men get a reality check.

| tonelord 3 months ago | root | parent | prev | next [–] I like it too. But I think the training is to realize that human brains are already far behind detecting AI generated content as of 2025/26, and our brains probably won't ever catch up.

| looperhacks 3 months ago | parent | prev | next [–] How do you know that the videos are AI or not? For many of them it's pretty clear, but I imagine not every user is labelling their AI uploads properly

| tomwojcik 3 months ago | root | parent | next [–] I only add the ones where its proved its AI, fe. if it has SynthID or some users found obvious AI mistakes. I have adding proof on the roadmap, but it's a bit tidious and there's no point in making it without a traffic.

| surround 3 months ago | root | parent | next [–] How do you know if it's real?

| GSSmarin 3 months ago | parent | prev | next [–] It would be cool if you could see the image/video again after choosing. I always want to watch it again after a wrong guess.

| tomwojcik 3 months ago | root | parent | next [–] Hmm, I will consider adding "close" button for the overlay popup. Thanks for the feedback

| mosselman 3 months ago | parent | prev | next [–] Very fun. You have hidden the controls on the video, is it because you want it to be more of a game and prevent people, normies at least, from seeking through the video or is it for some other reason?

| himata4113 3 months ago | parent | prev | next [–] I am too skeptical of videos and way too trusting of photos I guess.

| rolls-reus 3 months ago | parent | prev | next [–] i honestly would have believed some of the AI ones were real if i had come across the them elsewhere. i wonder if doing a more even real / ai would make it harder to get it right.

| paulhebert 3 months ago | prev | next [–] I'm still having a lot of fun releasing daily puzzles for my game Tiled Words: https://tiledwords.comIt just won an award! It was awarded Players' Choice out of 700 daily web games at the Playlin awards: https://playlin.io/news/announcing-the-2025-playlin-awards-w...Right now around 3,500 people play every day which kind of blows my mind!It's free, web-based, and responsive. It was inspired by board games and crosswords.I've been troubleshooting some iOS performance issues, working on user accounts, and getting ready to launch player-submitted puzzles. It's slow going though because I have limited free time and making the puzzles is time consuming!Here's an article with more info about the award: https://cogconnected.com/2026/03/tiled-words-crowned-the-pla...

| linsomniac 3 months ago | parent | next [–] My wife and I just finished our morning Tiled Words and Bracket City. It's become part of our morning routine. Thanks for it, it's a lot of fun!

| paulhebert 3 months ago | root | parent | next [–] That’s awesome, thanks!Bracket City is great! Definitely one of my favorites

| abraxas 3 months ago | parent | prev | next [–] Than you for Tiled Words. It quickly became a morning ritual to complete the daily puzzle. I wish there were more mobile games that are not obnoxious. The idea and the execution are top notch.My only concern is that there is a buzzing noise if the app is in the foreground and some audio is playing in the background. This is on pixel 9a

| paulhebert 3 months ago | root | parent | next [–] Thanks for playing!Oh interesting, thanks for the bug report! I hadn’t heard that one yet. I’ll look into it

| abraxas 3 months ago | root | parent | next [–] You're welcome, thanks for making it! The noise is intermittent and may simply be CPU/GPU overload and the resulting sound distortions. But it could be something else. It is quite reproducible on my phone.

| paulhebert 3 months ago | root | parent | next [–] It may be related to the library I'm using for sound effects

| tclancy 3 months ago | parent | prev | next [–] I think I am getting close to a 100 day streak. Thanks!

| paulhebert 3 months ago | root | parent | next [–] Awesome, thanks for playing!!

| suzdude 3 months ago | parent | prev | next [–] I don't play every day, but I've been a big fan of Tiled and showed it to a number of other folks.Thank you so much for keeping it going!

| paulhebert 3 months ago | root | parent | next [–] Thanks for playing and sharing!

| jasondigitized 3 months ago | parent | prev | next [–] How did you go from 0 users to 3,500? Genuinely curious how people get their games off the ground.

| paulhebert 3 months ago | root | parent | next [–] It's been a gradual process over the last 5.5 months. Here are some of the things that worked for me:- I applied to showcase the game at the Portland Retro Gaming Expo with the Portland Indie Game Squad. They accepted me so I was able to showcase it at the expo for a day. This got me some players right off the bat- I shared it on HN, Reddit, Mastodon, etc.- The website Thinky Games wrote an article about it- The YouTube channel Cracking the Cryptic shared it which got a lot of new players. More recently a couple of other YouTubers (Timotab and Stro Solves) have been posting videos regularly- I link to it from my blog, and this unrelated rant went semi-viral in web dev circles: https://paulmakeswebsites.com/writing/shadcn-radio-button/- Winning the award gave me more visibility and playersI've also tried using things like Instagram and Discord but haven't had much luck there. I don't really get how those platforms work.To be honest I'm not great at marketing. I've just been experimenting and seeing what works.---I would say the most important thing is the game itself:- I've worked hard to gather feedback and incorporate it into the gameplay.- I focus on keeping the puzzles fresh and striking the right difficulty level. (Challenging but something most people can do in 10 minutes.)- I built a sharing feature that ~300 or so people use a dayI think all my marketing would have been useless if people didn't like the game and want to play again and share it with their friends.

| vintagedave 3 months ago | root | parent | next [–] I remember seeing this! It was cool, and I will remember to play it more.Re creating puzzles, does this mean you have to manually do them one per day? Is there a way to automate them ahead of time (as in have an app generate a bunch of puzzles you can pick from or tweak)?

| paulhebert 3 months ago | root | parent | next [–] This is something I’ve been grappling with.I’ve automated parts of the process. Once I have the words and clues I can autogenerate crosswords and pick the best one.I’m hesitant to automate the creation of the theme, words, and clues though. I worry that the quality would go down but there may be some opportunities to speed up brainstorming there. I’ve been noodling on this.

| bengale 3 months ago | parent | prev | next [–] That's a lot of fun, good work.

| paulhebert 3 months ago | root | parent | next [–] Thanks!

| popupeyecare 3 months ago | prev | next [–] Im building https://trypixie.com to legally employ my 7 year old child, save on taxes and contribute to her Roth IRA.Im also building https://www.keepfiled.com, a microsaas to save emails (or email attachments) to google driveI almost forgot, I also built https://statphone.com - One emergency number that rings your whole family and breaks through DND.I love building. I built all these for myself. unfortunately I suck at marketing so I barely have customers.

| yangikan 3 months ago | parent | next [–] Do you use Twilio for statphone? Or SIP? I want to build a telephony app, but the economics don't work out with Twilio.

| popupeyecare 3 months ago | root | parent | next [–] The economics don’t work for StatPhone either but I figured if it has value, I can find other ways to make money or bring down costs.

| yangikan 3 months ago | root | parent | next [–] Thank you - I figured Google Voice provides basic multiple rings facility. What are the extra things that you provide on top of that?

| popupeyecare 88 days ago | root | parent | next [–] I actually don't know if Google Voice has that capability unless you hack it by having each phone logged into the same account.The biggest benefit for me with StatPhone is the incoming callerID is the StatPhone number. So even if the kid's school is calling from a random number, on your phone it shows the StatPhone number and you know its a call pertains to your child.Also grouped escalation, so if my father calls in an emergency, the kids get called first and then the in laws and our uncle.

| rhoopr 3 months ago | parent | prev | next [–] Can you clarify how Statphone deals with the problem of random spam calls hitting the number by chance and ringing everyone? I assume that’s how most spam operates these days, just brute force on number permutations. I love the idea!

| popupeyecare 3 months ago | root | parent | next [–] Sure!Unfortunately if a spammer called the StatPhone number, it would dial everyone. I thought about blocking or automatically categorizing but then you may miss an important call from an unknown number.Most spammers are actually operating off of known lists, usually made off of some data leak.I haven’t encountered that issue yet. I don’t have a great solution for that case.

| rhoopr 3 months ago | root | parent | next [–] Fair enough! It's an extremely hard problem to solve.

| sakopov 3 months ago | parent | prev | next [–] How do escalations work for statphone? If the first group doesn't respond to the call, does it escalate to the second group while the call is in progress still? What happens if the caller hangs up? Very cool idea btw!

| popupeyecare 3 months ago | root | parent | next [–] Hi!If the first group doesn't pick up, it starts calling the second group, but first group continues to ring.If the caller hangs up, all ringing is stopped.The cool thing is if it encounters the native phone's voicemail, it hangs up and continues to ring so doesn't think it was a picked up call.We do have our own voicemail that will eventually answer (user defined timing), which then transcribes and sends the voicemail+transcription to all the group members.

| codazoda 3 months ago | parent | prev | next [–] Me too. Maybe we could mastermind? Reach out, my email is in my profile.

| sunnybeetroot 3 months ago | parent | prev | next [–] Amazing landing for statphone, mind if I ask if it’s using any sort of UI library?

| hju22_-3 3 months ago | root | parent | next [–] I must concur, very tasteful.

| otterley 3 months ago | parent | prev | next [–] Did you consult any tax lawyers before releasing trypixie? Feels super risky.

| popupeyecare 3 months ago | root | parent | next [–] I did and a few CPAs. Surprisingly my customers have been CPAs buying to offer to their clients.Pixie is more like quickbooks or any other record keeping software. We don’t employ the children, their parents do. And as long as the kids are doing legitimate work, it’s fair and actually the irs has a page on it. https://www.irs.gov/businesses/small-businesses-self-employe...

| sudokatsu 3 months ago | parent | prev | next [–] Statphone is such a genius idea - very cool.

| hmokiguess 3 months ago | parent | prev | next [–] Love these, really cool!

| samename 3 months ago | parent | prev | next [–] these are all great ideas!

| Reforest8973 3 months ago | parent | prev | next [–] TryPixie is a great idea

| dataviz1000 3 months ago | prev | next [–] I'm using TimescaleDB to manage 450GB of stocks and options data from Massive (what used to be polygon.io), and I've been getting LLM agents to iterate over academic research to see if anything works to improve trading with backtesting.It's an addictive slot machine where I pull the lever and the dials spin as I hope for the sound of a jackpot. 999 out of 1000 winning models do so because of look-ahead bias, which makes them look great but are actually bad models. For example, one didn't convert the time zone from UTC to EST, so five hours of future knowledge got baked into the model. Another used SELECT DISTINCT, which chose a value at random during a 0–5 hour window — meaning 0–5 hours of future knowledge got baked in. That one was somehow related to Timescale hypertables.Now I'm applying the VIX formula to TSLA options trades to see if I can take research papers about trading with VIX and apply them to TSLA.Whatever the case, I've learned a lot about working with LLM agents and time-series data, and very little about actually trading equities and derivatives.(I did 100% beat SPY with a train/out-of-sample test, though not by much. I'll likely share it here in a couple weeks. It automates trading on Robinhood, which is pretty cool.)

| mmaunder 3 months ago | parent | next [–] Nice. I played with this a bit. Agents are very good at Rust and CUDA so massive parallelization of compute for things like options chains may give you an edge. Also, you may find you have a hard time getting very low latency connection - one that is low enough in ms so that when you factor in the other delays, you still have an edge. So one approach might be to acknowledge that as a hobbyist you can't compete on lowest-latency, so you try to compete on two other fronts: Most effective algorithm, and ability to massively parallelize on consumer GPU what would take others longer to calculate.Best of luck. Super fun!PS: Just a follow-up. There was a post here a few days ago about a research breakthrough where they literally just had the agent iterate on a single planning doc over and over. I think pushing chain of thought for SOTA foundational models is fertile ground. That may lead to an algorithmic breakthrough if you start with some solid academic research.

| dataviz1000 3 months ago | root | parent | prev | next [–] I'll notice that the trading model will filter out bear down trends which is very, very helpful but it doesn't trade short. I'll ask the coding agent to find several academic research papers about trading once intraday during a down trend -- a single scalping. It will return with ~10 references. It will recreate the model, do statistical analysis, and create a search grid backtest. This will immediately give information if there is any alpha. If there is, it will iterate integrating the concept into the existing trading model.It has enough information that it will continue to iterate for the next several hours.It's all happening in a black box. I have no idea. My concern isn't trading but rather to get it to continuously improve unsupervised without lying or hallucinating.

Since last month we got deals with a couple more search providers but we’re still waiting for EUSP/STAAN to provide us with an API key (we have progressed through a few more forms and signatures and legal stuff, though).We’ve continued to get some paid customers and have exited beta last week, given everyone seemed to be quite satisfied and there hadn't been requests for changes, only some specific search providers.Because of bots there isn’t a free trial easily available, but if you’re a human and you’d like to try it for a couple of days for free, reach out with your account number and we’ll set that up!Thanks.P.S.: Because people have asked before, our tech stack is intentionally very "boring" (as in, it generates and serves the HTML + bits of JS to enhance settings and such — search can be done without JS), using Deno in the backend (for easier TypeScript), PostgreSQL for the DB, and Docker for easier deploying.[1] https://uruky.com

| mschild 3 months ago | parent | next [–] Surprisingly, I haven't heard of Uruky yet, even though I'm actively looking for EU replacements to a lot of international companies.I have subscribed for a month and will give it a try.One feedback already though. Some of the German translations are...not great. For example, on the landing page under the "Not another AI tool". In English you write "We find it hard to do in a sensible, responsible, and respectful way." In the German translation its "Es fällt uns schwer, vernünftig, verantwortungsvoll und respektvoll zu handeln."The German translation makes it sound like you (as in you as a company and person) have a hard time being respectful, not the actual AI implementation.

| BrunoBernardino 3 months ago | root | parent | next [–] Thank you so much for the kind words, suggestions, and support! We don't natively speak German, and we used DeepL for most of the translations.We are currently working with a professional technical translator for German (should get updated translations in a week or two) and will consider that for other languages, but it's quite expensive to do more of that right now.

| alabhyajindal 3 months ago | parent | prev | next [–] Hi Bruno - this looks great! I remember collaborating with you a couple times on Kagi's browser extensions. Was there a specific moment that made you want to work on Uruky, or was it because of the overall direction Kagi is heading in?

| BrunoBernardino 3 months ago | root | parent | next [–] Hey Alabhya! Nice seeing you here! :)I don't think Kagi is heading in a necessarily "bad" direction, though I don't agree with it, and I also think there's value in a product that's solely focused on private and personal search, that doesn't have to be as expensive, expansive (Drive, Maps, Email, etc.) or big (team and resources-wise) as they are.I hope that makes sense!

Like Kagi it wraps / reuses multiple other providers? How do you do that affordably, and how do you merge the results together into a good answer?

| BrunoBernardino 3 months ago | root | parent | next [–] Thanks! Sure. We are 100% transparent on all the search providers we're using, you can see them in the FAQ, and Yandex isn't used.Initially we called all search providers and merged the results in a round robin fashion (so first of the first provider, first of the second provider, first of the third provider, then second of the first provider, second of the second provider, and so on), deduplicating them, but this was becoming very costly and inefficient once we had 3 and more search providers (most providers will return results within 500ms, but not infrequently one would take up to 2s or more — we timeout there, so I don't know if it'd take much more —, slowing everything down), so now we give everyone the choice of which providers to use first, and we pick results from the first two (we're actually considering switching to just the first, as costs are still a bit high and we don't want to increase pricing).I hope that provides some more clarity! Happy to answer any more questions.

So safe to.say that's what most of your users will also think of.

I had some free API credits, and used a naive workflow:while word_count < x: write_next_chapter(outline, summary_so_far, previous_chapter_text)It worked well enough that the novels were better than the median novel aimed at my son's age group, but I'm pretty sure we can do better.There are web-based tools to help fiction authors to keep their stories straight: they use some data structures to store details about the world, the characters, the plot, the subplots etc., and how they change during each chapter.I am trying to make an agent skill that has two parts:- the SKILL.md that defines the goal (what criteria the novel must satisfy to be complete and good) and the general method- some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)- a python file which the agent uses as the interface into the data structure (I want it to have a strong structure, and I don't like the idea of the agent just editing a bunch of json files directly)For the first few iterations, I'm using cheap models (Gemini Flash ones) to generate the stories, and Opus 4.6 to provide feedback. Once I think the skill is described sufficiently well, I'll use a more powerful model for generation and read the resulting novel myself.

| rond2911 3 months ago | parent | next [–] this is fascinating. I would like to try this as a side project as well.some other md files that describe different roles (planner, author, editor, lore keeper, plot consistency checker etc.)- What are these meant to be exactly? are these sub agents in the workflow or am i completely misunderstanding?

| rahimnathwani 3 months ago | root | parent | next [–] "are these sub agents in the workflow"The idea is that on any 'turn', the AI model should be doing only one of those tasks. That's true whether it's in the main thread (with all the past context) or has just been launched as a subagent.You can see an example of this pattern here in Anthropic's skills repo: https://github.com/anthropics/skills/tree/main/skills/skill-... (the repo has four separate skill.md files: a main SKILLS.md and then three others for specialist roles)Whether they're run as subagents (a separate AI chat session with clean context) is a separate decision, and it depends on whether the coding harness supports that. https://agentskills.io/client-implementation/adding-skills-s...I'm still trying to figure out the subagent delegation stuff.

| TheAceOfHearts 3 months ago | prev | next [–] I vibe coded a tiny MUD-style world sim where LLMs control each character. It's basically a little toy sandbox where LLMs can play around. There's no real goal to this, I just thought that it would be fun, like a more advanced tamagochi.One of the issues I encountered initially was that the LLMs were repeating a small set of actions and never trying some of the more experimental actions. With a bit of prompt tweaking I was able to get them to branch out a bit, but it still feels like there's a lot of room for improvement on that front. I still haven't figured out how to instill a creative spark for exploration through my prompting skills.It has been quite exciting to see how quickly a few simple rules can lead to emergent storytelling. One of the actions I added was the ability for the agents to pray to the creator of their world (i.e. me) along with the ability for me to respond in a separate cycle. The first prayer I received was from an agent that decided to wade into a river and kneel, just to offer a moment in stillness. Imagining it is still making me smile.Unfortunately, I don't have access to enough compute to run a bigger experiment, but I think it would be really interesting to create lots of seed worlds / codebases which exist in a loop. With the twist being that after each cycle the agents can all suggest changes to their world. This would've previously been quite difficult, but I think it could be viable with current agentic programming capabilities. I wonder what a world with different LLM distributions would look like after a few iterations. What kind of worlds would Gemini, Claude, Grok, or ChatGPT create? And what if they're all put in the same world, which ones become the dominant force?

I want to show how I liberate poorly aligned, pixelated PDF image scans of century-old Latin textbooks from the Internet Archive and transform them into glorious Org mode documents while preserving important typographic details, nicely formatted tables, and some semantic document metadata. I also want to outline how to integrate a local lemmatizer and dictionary to quickly perform Latin-to-English lookups, and how to send whole sentences to Gemini for a detailed morphological and grammatical breakdown.I also intend to dig into how to integrate Emacs with tools such as yt-dlp and patreon-dl to grab Latin-language audio content from the Internet, transcode the audio with ffmpeg, load it into the LLM's context window, and send it off for transcription. If the essay isn't already too long, I'll demonstrate how to gather forced-alignment data using local models such as wav2vec2-latin so I can play audio snippets of Latin texts directly from a transcription buffer in Emacs. Lastly, I want show how to leverage Gemini to automatically create multimedia flash cards in Org mode using the anki-editor Emacs minor mode for sentence mining.

| mohsen1 3 months ago | prev | next [–] Wanted to see if AI could figure out how to compress executable binaries better than existing generic tools without me actually knowing much about compression engineering or ELF internals.The result is an experiment called fesh. It works strictly as a deterministic pre-processor pipeline wrapping LZMA (xz). The AI kept identifying "structural entropy boundaries" and instructed me to extract near-branches, normalize jump tables, rewrite .eh_frame DWARF pointers to absolute image bases, delta-encode ELF .rela structs with ZigZag mappings, and force column transpositions before compressing them in separated LZMA channels.Surprisingly, it actually works. The CI strictly verifies that compression is perfectly reversible (bit-for-bit identity match) across 103 Alpine Linux x86_64 packages. According to the benchmarks, it consistently produces smaller payloads than xz -9e --x86 (XZ BCJ), ZSTD, and Brotli across the board—averaging around 6% smaller than maximum XZ BCJ limits.I honestly have no idea how much of this is genuinely novel versus standard practices in extreme binary packing (like Crinkler/UPX).Repo: https://github.com/mohsen1/feshFor those who know this stuff:Does this architecture have any actual merits for standard distribution formats, or is this just overfitting the LZMA dictionary to Alpine's compiler outputs? I'd love to hear from people who actually understand compression math.

Some of them are just normal adulting recipes. Some are meal prep. Some are too struggly for a legitimate recipe site.I have some barebones content at https://struggle-meals.wonger.dev/ and will be working on the design over the next few weeks. Some decisions I'm thinking about:- balancing between personal convenience and brevity vs being potentially useful for other people. E.g. should I tag everything that's vegan/vegetarian/GF/dairyfree/halal/etc? Should I take pictures of everything? (I'd rather not)- how simple can I make a recipe without ruining it? E.g. can I omit every measurement? should I separate nice-to-have ingredients from critical ingredients? how do I make that look uncomplicated? (Sometimes the worst thing is having too many options)- if/how to price things? Depends on region, season, discounts, etc

| reedlaw 3 months ago | parent | prev | next [–] Do you have examples of the task maturation cycle? I'm not sure how it would work for tasks like extracting structured data from images. It seems it could only work for tasks that can be scripted and wouldn't work well for tasks that need individual reasoning in every instance.

| juanpabloaj 3 months ago | root | parent | next [–] No practical code example, sorry. The post is based on my own experience using agents, and I haven't reached a reusable generalization yet.That said, two cases where I noticed the pattern:Meal planning: I had a weekly ChatGPT task that suggested dinner options based on nutritional constraints and generated a shopping list (e.g. two dinners with 100g of chicken -> buy 200g). After a few iterations, it became clear that with a fixed set of recipes and their ingredients, a simple script generating combinations was enough. The agent's reasoning had already done its job — it helped me understand the problem well enough to replace itself.QA exploration: I was using an agent to explore a web app as a QA tester. It took several minutes per run. After some iterations, the more practical path was having it log its explorations to a file, then derive automated tests from that log. The agent still runs occasionally, but the tests run frequently and cheaply.Regarding your point about tasks that need individual reasoning every time — I think you're right, and that's actually the core of the idea. Not every task matures into a script. Extracting structured data from images probably stays deliberative if the images vary significantly. The cycle only applies to tasks that, after enough repetitions, reveal a stable pattern. The agent itself is what helps you discover whether that pattern exists.

| tow21 3 months ago | prev | next [–] For language geeks: https://kpt.datamediate.comKPT is a language app specifically targeted at explainable verb conjugation for highly inflected/agglutinative languages. Currently works for Finnish, Ukrainian, Welsh, Turkish and Tamil.These are really hard languages to learn for most speakers of European languages, particularly English - we're not used to complex verb conjugations, they're hard to memorise and the rules often feel quite arbitrary. Every other conjugation practice app just tells you right/wrong with no explanation, which doesn't really help you learn when there are literally hundreds of rules to get right.The interesting part was using an LLM to create a complete machine-executable set of conjugation rules, which are optimized for human explainability, and an engine to diagnose which rule is at fault when you get it wrong. There's several hundred rules needed for each language in order to cover all exceptions.NB as a bonus it also works fully offline because my best practice hours are when I'm travelling and have poor connectivity.

| brynnbee 3 months ago | prev | next [–] I made an idle version of the 1999 MMORPG "EverQuest". There's maybe around 50 people playing at any given time and has a enthusiastic discord group for it. It's relatively fully-featured to the original game, and has a lot of new mechanics to make the idle format work well. The 3D graphics aspect of it is really more of a screensaver, though, and all game interactions are done through menus.I recently converted a bunch of stuff to be client side instead of server side (turns out running a real-time MMORPG server is expensive) so there's a new round of bugs I'm still resolving, but it's still fun to play:https://www.idlequest.net/

| loumaciel 3 months ago | prev | next [–] I’m building Sift, a drop-in gateway that makes LLM tool use far more reliable when tools return large JSON payloads. The usual pattern is that agents paste raw tool outputs directly into the prompt, which quickly blows up context, causes truncation/compaction, and leads to incorrect answers once earlier results disappear. Sift sits between the model and its tools (MCP, APIs, CLIs), stores the full payload locally as an artifact (indexed in SQLite), and returns only a compact schema plus an artifact_id. When the model needs something from the data, it runs a tiny Python query against the stored artifact instead of reasoning over thousands of tokens of JSON. In benchmarks across 103 questions on real datasets, this approach cut input tokens by ~95% and improved answer accuracy from ~33% to ~99%. Repo: https://github.com/lourencomaciel/sift-gateway.

| mattmanser 3 months ago | parent | next [–] I was talking about part of this problem this morning, I keep having it with our large OpenAPI spec and the JSON parsing. But it occured to me that recently sometimes Claude will work around the context blowing problem by using a sub-agent to do the parsing. Have you seen that?It's still a big time saver to have something like this, and stops it even taking the risk of doing it in the first place.

| merlindru 3 months ago | prev | next [–] Tool that lets you build shortcuts and custom functionality for most macOS apps. You write JS snippets like this:

const app = new App("com.apple.finder")

and then query for elements:

const window = app.$({role: "window"}) const someButton = window.$(/ another query /)

and then do stuff with it:

someButton.press()

and you can bind everything to very specific shortcuts like "press and hold cmd, then scroll mouse wheel up"Targeted towards music producers and AI (there's one collection of snippets that starts an MCP server and exposes some basic functionality) in the beginning.

| hsaliak 3 months ago | prev | next [–] https://github.com/hsaliak/std_slop a sqlite centric coding agent. it does a few things differently. 1 - context is completely managed in sqlite 2 - it has a "mail model" basically, it uses the git email workflow as the agentic plan => code => review loop. You become "linus" in this mode, and the patches are guaranteed bisect safe. 3 - everything is done in a javascript control plane, no free form tools like read / write / patch. Those are available but within a javascript repl. So the agent works on that. You get other benefits such as being able to persist js functions in the database for future use that's specific to your codebase.Give it a try!

| robalni 3 months ago | prev | next [–] I just started building an operating system that will be written entirely in one text file. This text file includes in order: a readme, a RISC-V assembly boot code, then the rest. You run it by compiling the initial boot code with a RISC-V assembler, then you concatenate the binary with the whole text file itself. Then when you run it, the boot code will compile the rest of the text file (the operating system), including higher level language compilers that the rest of the system will be written in.This is the kind of project that creates something from as little as possible, where the only things you need to get started are a very basic RISC-V assembler and a computer or emulator to run it on.I don't have anything interesting to show yet because I just started yesterday, but one day I will show you.

| pipnonsense 3 months ago | prev | next [–] A soccer web game where you are the coach and your only possible interaction is shouting (ie typing) messages to your players from the sidelines. An LLM interpret your messages and pass instructions into the game engine.It is a pretty fun project

| mbreese 3 months ago | parent | next [–] I could see this being a very eye opening game if you added "Fan" and "Parent" modes. In "fan" mode nothing you said would affect the game, although maybe a player would laugh once in a while. In "parent" mode, you'd have a youth soccer game where whatever you said would confuse the player and they'd perform worse.Sounds like a fun project -- like a more interactive version of Football Manager.

| pipnonsense 3 months ago | root | parent | next [–] Neat ideas.One thing I am exploring is that, with LLM (and enough $ to pay the tokens) you can filter out offenses and hate speech in player communications.All typed message is effectively translated by the LLM as “coach speech” and what is put in the UI is the LLM output. Sure, it is not exactly the player words and can get expensive, but I think it can be a good solution

| mbreese 3 months ago | root | parent | next [–] It's really a good idea. I've spend a little time on the sidelines as a coach (and parent and ref, but that's another story) and one thing that I think is crazy is the differences in what you think you can affect, and what you really can affect from the sideline. The technical area is a really small facet on the larger game, so I think your idea would make for a fun game. And knowing how much time my son spends playing Football Manager, I think there's an audience for it!

| vkoskiv 3 months ago | prev | next [–] My hobby x86 kernel. I'm targeting my 80486DX2-66 PC with 32MB of RAM. This project has had a few false starts over the years, where I lacked the prerequisite knowledge to be able to properly debug things. So while the initial commit is from 2020, most of the progress is from the ~180 or so commits I've done in the last month since I picked it up again in early February. A month ago it booted from a floppy and printed some debug info to the screen showing it set up GDT, IDT and some static page tables. Now I have basic virtual memory with kmalloc()/kfree(), task switching, user mode and a few syscalls, and just this past weekend I got my floppy driver to a state where it can now (semi-)reliably detect and read data off floppy disks. I already have a userspace prototype of an ext2 parser I wrote for this in 2024, so all I need to do now is to bring that code in to the kernel and I should have filesystem support!It's been a ton of fun to work on. Every subsystem is still flaky so I run into the wackiest bugs imaginable. I'm really grateful for the resources[1] and incredible tooling[2] that enable me to work out my frequent mistakes. I can hardly fathom how Torvalds did this with just his PC running Minix!No idea how long I'll keep working on it. I think I'd be pretty happy if I got a real-world, non-trivial program running on top of it, but in the meantime it is serving as a good distraction from life worries at least :][1]: Intel 80386 Reference Manual, Linux man pages, wiki.osdev.org, various datasheets and the occasional query to ChatGPT free tier.[2]: QEMU+gdb, Bochs, GCC 9 & binutils

| vkoskiv 3 months ago | root | parent | next [–] Nice! My keyboard code is still very bare bones, so I interact with my system using debug commands assigned to individual keys.Since we're both working on a similar project, I think it could be fun to talk about OS development and share our findings (and weird bugs!) I have this same username just about everywhere, so do reach out if you're interested! Best of luck with your project either way :]

| medbar 86 days ago | root | parent | next [–] Gladly! Since my last comment I added sound support through an ac97 driver. It was fairly straightforward in hindsight, only had an issue with the interrupt not being handled - turns out my ISR stubs weren't fleshed out to handle IRQs, just the cpu exceptions. Also had a minor bug where addresses outside of the kernel weren't getting translated properly, which I hadn't tested before and assumed to be correct.I probably could have saved myself 2+ hours of debugging if I had simply stopped working off of assumptions that my driver code was wrong (it was, but that just took reading the spec and checking out some drivers for reference) and doing a root cause analysis with objdump or through QEMU. Still surprised how far you can go with vanilla debugging prints - when I started this project, I was sure that I'd become fluent in gdb as a byproduct, but I stopped using it once it would break when the stack became corrupted and haven't tried it since.Discussion is the reason I made the jump from lurking to having an account on HN. Happy to talk - reached out to you on twitter. And good luck to you as well :^)

| ehnto 3 months ago | prev | next [–] An immobiliser for my car. Had trouble finding devices that would cover the specific attack vectors my car would be susceptible to. Checked my insurance, no specific clauses around immobilisers, check relevant road laws, no issues there.I have a fairly novel approach to operating it, and in the case of one time theft prevention security through obscurity is actually a great approach. The assailant only has a short time to pull the car apart and solve the puzzle, couple that with genuine security techniques, a physical aspect, and it should be pretty foolproof.It can still be towed away, etc, not much to be done there except brute force physical blocks. Most cars get stolen here to do crime in that night so it's not as common.

Also added buttons (including HN :)) so people can just click click and get their stories at their level with their interests.- Made sure people can generate stories without ever signing up- Each word is highlighted while being read, and the meanings can be checked with a tap. I also added an option for users to read the sentence for being checked how good their pronounciation is.- Benchmarked 7 different models to get the fastest & highest quality story generation (it’s gemini now) and it’s insanely fast. I might share more about it on the webpage because I am an engineer and I enjoy this stuff lol.- Added CSV import in Use my words so Anki users can just import their words to study.- Also people can download their stories as pdf so they can send it to their kindles.- I am working on a ChatGPT app, so people can just say “@DuoBook give me a Dutch/English story on latest Iranian events” within ChatGPT, but I am a bit afraid that it might be costly lol.

| gahays68 89 days ago | prev | next [–] Because 9 out 10 Startups fail, early startup investing is not investing, it’s philanthropy with a potential upside. So I’ve created a new game of Venture call VentureStaking where multiple people come together to form a grant for a founder (no debt / no equity) to spend a year researching a problem (ie Thiel Fellowship) and then if that founder discovers something interesting, the grantors can invest up to 10x their grant amount in equity. So, for example, a $100,000 grant creates a potential $1MM equity round to keep the momentum going. Thus, a VentureStaker can give $10 grants to 100 Founders to discover the 3-4 that come up with a great opportunity and invest 10x in those rounds. The SEC has been vetting this system for 8 months and cannot conclude it’s a security which means that we can operate VentureStaking without expensive legal compliance. SEC rules are only triggered at the first equity round and RegCF can allow multiple retail investors in as one line item on the cap table. So now, it’s a game of Discovery to start and smarter investing later. To learn more, go to Doriot dot com.

Many yarncrafters painstakingly build spreadsheets, or try to bend existing general purpose pixel editors to their will. It's time consuming & frustrating.Along the way, I've solved a bunch of problems:

Automatic decreases (shapes the hat) / overstitching markers (shows when multiple colors are used in the same row)
Parameterized designs, like waves, trees, geometric shapes. No more manually moving an object by a couple of pixels, it's a simple click & drag.
Color palette merging (can't delete a color if you already use it in a pattern!)
Export to PDF (so you can print it or stick it on a tablet)
Repeat previews (visualize the pattern as it repeats horizontally)

The core feature that makes this more useful than most general purpose editors is that the canvas is continuous.If you drag a shape near the right edge of the canvas, you'll see it "wrapping around" onto the right edge.This reflects the 3D reality of a hat!

| mchaver 3 months ago | parent | next [–] I took a look at it because you do PDF generation (I am doing front-end PDF generation in my project as well so I wanted to compare), not because I know anything about knitting or crocheting.

The main thing I'm working on to that effect is https://homelore.orgIt's like a carfax but for your home, although the intention is more to create an interesting historical narrative that inspires people to care about the history of their home rather than as a tool for inspecting home issues before buying.My target customer is realtors who want to inspire buyers to take on historic homes that may need a lot of work. Also home owners themselves of course.

| skypanther 3 months ago | parent | next [–] This looks great and I'll probably order a report. A couple of small suggestions. First, the price is very reasonable, but I think you should be more open about what it costs -- maybe on the home page or at least the Order Report page. Second, I think you should tell what areas of the country (world?) that you can provide reports for, again on the main page would be great.

I've put one of them in lan mode for testing, but I'm pretty close to replicating the important handy (Bambu's cloud app) features, at which point I'll be able to start adding the really nice.She sells a product with 16 different printed parts, and she prints the parts in bulk batches across 7 different pause points, some of which have pause points for embedding magnets.The idea is to integrate inventory management and print scheduling into the tool, which will be nice.I have working so far: * Pulling camera images * Pulling the currently printing file, including the preview image (rendered in bambu studio and bundled with the print; standard for bambu studio), and the pause points * A dashboard with projected timing information * Notifications about jobs starting, stopping & pausing * Remote printer controlNext on the list: * Delayed printing - schedule a print to start in the night. Mostly useful so that if there's a pause point we don't leave a print paused for hours on end. * Print queueing - manually build a list of prints so that after switching plates we can just "next print" for a printer * Print scheduling - select a quantity of print files or groups of files to print, and have it schedule the prints, including projected switch times, to maximize printer utilization by avoiding jobs ending at night * Tracking magnet & filament usage, and integrating BoM and production quantity tracking.I've been mostly AI coding this, but I've go in to make it extract out components, etc. And I lay down and enforce the DB schema. I've had to ask it to back out a few things entirely. And I've had to give it the Bambu API docs I found github. But it's been going pretty well.

| bilsbie 3 months ago | parent | next [–] This is so cool. Why does 3d printing make sense vs injection molding? Low volume? To many customizations?

| swsieber 3 months ago | root | parent | next [–] To be honest, we should probably go into injection molding. We do have a pretty long tube in there that might be a bit problematic for injection molding from what I've read (1 degree draft means the tube size inside changes by 1/8 of an inch), and the orientation of the magnets is pretty important, and they can repel each other pretty hard to. So part of it is the unknowns.The other part is the upfront cost. I bet we'll get to injection molding in the next few months as revenue allows, and we're going to start exploring it this month I think. We'd like to keep things local, though we know we'll still have to contend with knock offs sooner than later.

| PAndreew 3 months ago | prev | next [–] Managed BYOK stateless agent orchestrator called BeeZee: https://beezyai.net/. Basically Claude Cowork / a coding agent on the web but provider agnostic, you own the data and you can connect several nodes to it. Instead of installing an agent for all your machines you have one master agentic server and executor nodes. The server is stateless the data lives on the nodes and in a managed database. I use Supabase and Google KMS so my auth keys are encrypted. Uses Pi agent under the hood. This enables me to code from my phone without a dedicated SSH terminal and without the need to babysit the agent. I describe the feature, off it goes, I close my phone and in 10 mins the results are there. Also using it to support my wife with white collar stuff like Excel analysis, translation, etc. It's a bit buggy but getting better.

| wisemang 3 months ago | parent | next [–] Nice! I’ve been working on https://treeseek.ca which is a different use case from most of the other open data tree sites I’ve seen — I want to be instantly geolocated and shown the nearest trees to me. I do a lot of walking and am often mesmerized by a particular tree, and I wanted something to help me identify them as quickly as possible, with more confidence and speed than e.g. iNaturalist (which i do also use).This is an app that’s been bouncing around in my head for over a decade but finally got it working well enough for my own purposes about a year and a half ago.

| efromvt 3 months ago | root | parent | next [–] Oh that's great! I was finding fun tree collections and wanted to go see them - unfortunately not in SF so not likely - but your app has some nice data around me that I can check out! Are you primarily using OSM data?I was thinking of a google maps kind of "here you are, here's your walking path of interesting trees" potentially, or something else that could tie the overview to the street experience - on the backlog!

| wisemang 3 months ago | root | parent | next [–] So the tree data itself mainly comes from municipal open data, just like yours does. Street Trees datasets are pretty common across cities. I just added SF yesterday after replying here :)Otherwise the map tiles are coming from OpenFreeMap [1] which are indeed based on OSM.Next steps I'm interested in are including economic + ecological benefits of the trees, highlighting potential pests / invasive species, maybe some other basic info about the species sourced from Wikipedia.I like how you've got different icons for different types of trees; I've been thinking about how to encode DBH data as well but haven't settled on anything yet.[1] https://openfreemap.org

| efromvt 79 days ago | root | parent | next [–] Yeah I have a 'species' info table that's built by curating wikipedia and a few other sources and passing them through a structured LLM pipeline; ecological benefit; blooming season; native regions, etc. This is very much a 'rough cut' at the moment; I want to put more quality gates and evals in it. If you're interested in collaborating all the raw parquet datasets I have are in a public GCS bucket - happy to have them pulled in anywhere else!DBH I'm doing for the "size" right now, though I'd love to figure out how to get canopy shape/size as well, and height where possible. (and then maybe proxy height a species level from DBH, since that's more common).(apologies for belated response)

HSL color pickers that most design tools like Figma use have the very counterintuitive property that the hue and saturation sliders will change the lightness of a color (which then impacts its WCAG contrast), which HSLuv fixes to make it much easier to find accessible color combinations.I'm working on a Figma plugin version so you can preview colors directly on a Figma design as you make changes.

Maybe we can mob on this problemscape together.> I do wonder if the problem is not so much having a place to find LAN events but actually just having enough people put on LAN events in the first place.Sort of! I did a lot of research on this before I built lan.events. There are more gamers than ever, but LANs dropped off during COVID lockdowns despite surveys showing an increasing interest in in-person events. More or less, it's actually a venue problem. Running events has incredibly thin and risky margins for something that by its very nature needs to be planned out months in advance. Everything around the events are becoming prohibitively expensive: venues, vendors, equipment rentals, etc are all eating away at the ceiling gamers will pay and the floor that organizations can charge from.LAN.events helps tackle this by decreasing the cost per ticket and shifting that cost to the customer rather than the event manager. We don't introduce minimum event costs or percentage based pricing which lets event managers keep or give back more profits. There is more I can do in this space, but that's the biggest way I can contribute right now.

| heyitssim 3 months ago | prev | next [–] I love making games, and I've been building a no-code game engine by extracting reusable components every time I ship a new game. It started as me scratching my own itch, and now it's turning into a real platform.Each game adds more building blocks to the editor: multiplayer, event systems, NPC behaviors, pathfinding, etc. I build a system once, and then anyone using the editor can use it in a click.Since my last month, I shipped the asset marketplace and the LLM builder. Artists can now upload tilesets and characters, and unlike itch.io, assets drop directly into the editor. You can preview how they'll actually look in-game before using them [1].An other problem I kept running into: even with a no-code editor, users don't know where to start. So now I'm extending it with a coding agent. Describe the game you want, and it assembles it — pulling assets from the marketplace, wiring up the event system, and using all the building blocks I've spent the past year extracting. Multiplayer, mobile controls, pathfinding, NPC behaviors — the agent doesn't build any of it, just reaches for what's already there.Once the LLM assembles it, users will have a game ready to work on, and will still be able jump into the editor and tweak everything [2]. Here's an example of what it can already make [3] (after a lot of prompting), and the goal is to reach games like this one I built with the manual editor[4].Hoping to release the AI mode in a week or two.

| diasks2 3 months ago | prev | next [–] I've been working on two small projects recently.1. Live Kaiwa — real-time Japanese conversation supportI live in a rural farming neighborhood in Japan. Day-to-day Japanese is fine for me, but neighborhood meetings were a completely different level. Fast speech, local dialect, references to people and events from decades ago. I'd leave feeling like I understood maybe 5% of what happened.So I built a tool for myself to help follow those conversations.Live Kaiwa transcribes Japanese speech in real time and gives English translations, summaries, and suggested responses while the conversation is happening.Some technical details: Browser microphone streams audio via WebRTC to a server with Kotoba Whisper * Multi-pass transcription: quick first pass, then higher-accuracy re-transcription that replaces earlier text * Each batch of transcript is sent to an LLM that generates translations, summary bullets, and response suggestions * Everything is streamed back to the UI live * Session data stays entirely in the browser — nothing stored server-sidehttps://livekaiwa.com---2. Cooperation Cube — a board game that rotates the playing fieldYears ago I built a physical board game where players place sticks into a wooden cube to complete patterns on the faces.The twist: the cube rotates 90° every round, so patterns you're building suddenly become part of someone else's board. It creates a mix of strategy, memory, and semi-cooperative play.I recently built a digital version.Game mechanics: 4 players drafting cards and placing colored sticks on cube faces * The cube rotates every 4 actions * Players must remember what exists on other faces * Cooperation cards allow two players to coordinate for shared bonuses * Game ends when someone runs out of short stickshttps://cooperationcube.com---Both projects mostly started as things I wanted to exist for myself. Curious what people think.

| mikeayles 3 months ago | prev | next [–] Rewriting the backend Bitwise Cloud, my semantic search for embedded systems docs Claude Code plugin from Python to Go.The problem was the ML dependencies. The backend uses BGE-small-en-v1.5 for embeddings and FAISS for vector search. Both are C++/Python. Using them from Go means CGO, which means a C toolchain in your build, platform-specific binaries, and the end of go get && go build.So I wrote both from scratch in pure Go.goformer (https://www.mikeayles.com/blog/goformer/) loads HuggingFace safetensors directly and runs BERT inference. No ONNX export step, no Python in the build pipeline. It produces embeddings that match the Python reference to cosine similarity > 0.9999. It's 10-50x slower than ONNX Runtime, but for my workload (embed one short query at search time, batch ingest at deploy time) 154ms per embedding is noise.goformersearch (https://www.mikeayles.com/blog/goformersearch/) is the vector index. Brute-force and HNSW, same interface, swap with one line. I couldn't justify pulling in FAISS for the index sizes I'm dealing with (10k-50k vectors), and the pure Go HNSW searches in under 0.5ms at 50k vectors. Had to settle for HNSW over FAISS's IVF-PQ, but at this scale the recall tradeoff is fine.The interesting bit was finding the crossover point where HNSW beats brute-force. At 384 dimensions it's around 2,400 vectors. Below that, just scan everything, the graph overhead isn't worth it. I wrote it up with benchmarks against FAISS for reference.Together they're a zero-dependency semantic search stack. go get both libraries, download a model from HuggingFace, and you have embedding generation + vector search in a single static binary. No Python, no Docker, no CGO.Is it better than ONNX/FAISS? Heck no. I just did it because I wanted to try out Go.goformer: https://github.com/MichaelAyles/goformergoformersearch: https://github.com/MichaelAyles/goformersearch

| liu3hao 3 months ago | prev | next [–] Hi HN, I am still working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/In the past month, as suggested by the previous user, I have added support for kicad schematic libraries. The kicad schematic libraries files are converted into circuitscript format and can be directly imported into circuitscript code. To support the large number of components in the kicad libraries, I had to improve the import functionality and also implement some caching to speed up the imports. With the kicad schematic libraries available now, it provides a larger library of components that can be used in circuitscript projects. The converted libraries can be found here: https://gitlab.com/circuitscript/kicad-librariesThe motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) for work in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.Please check it out and I look forward to your feedback, especially if you are also exploring alternative ways to create schematics. Thanks!

| liu3hao 3 months ago | root | parent | next [–] Thank you for taking a look at my project! But from what I can read in the JITx documentation, there are quite a few differences when compared to circuitscript. Firstly, they aim to provide a higher level design language compared to circuitscript, which targets only the schematic level at the moment. JITx goes beyond the schematic, and also does physical design as well as analysis. Secondly, JITx circuits are written in python, which honestly is clunky for defining the circuits as well as laying them out in a graphic schematic.

| mkovach 3 months ago | prev | next [–] This year, I decided to start opening up the tarball of random utilities that's been accumulating on my machine for years: stuff42.tar.gz.The first thing I cleaned up was TCL-Edit <https://gitlab.com/siddfinch/tcl-editor>, a small Tcl/Tk text editor I wrote a long time ago. After seeing the Rust clone of Microsoft EDIT, I realized the obvious next step was to build a Tcl/Tk clone of the Rust clone of Microsoft Edit. Recursion shouldn't be limited to code.I also built a tiny URL system in Perl <https://gitlab.com/siddfinch/perl-tiny-url>, meant to run locally. The idea is simple: short URLs for internal/VPN resources per client. I usually spin up a small daemon (or container) per client and get a dashboard of links I use frequently or recently.Security is intentionally minimal since it's local, which conveniently lets me ignore authentication and other responsible behavior.Goal for the year: Continue to open stuff42.tar.gz, pick something, clean it up just enough, and release it, and not have it by the end of the year.Might even choose a language that might even be described as "modern."

| cdr1987 3 months ago | prev | next [–] https://docules.net/aboutI've been building a collaborative docs tool called Docules. The short version: it's a team documentation tool that doesn't have any embedded AI features. I use Claude Code daily, but putting LLMs into every workflow and charging for it is kinda insane. Every docs tool is adding AI auto-complete, AI summaries, "generate a page" buttons. Docules has an API and an MCP server instead, so you connect whatever AI tools you actually want to use. The core product focuses on being a fast, solid docs tool. Real-time collab, fast — no embedded databases or heavy view abstractions, hierarchical docs, drag-and-drop, semantic search, comments, version history, public sharing, SSO, RBAC, audit logs, webhooks, etc. The stack is React, Hono, PostgreSQL, WebSockets. The MCP server is a separate package that exposes search, document CRUD, and comments — so Claude/ChatGPT can work with your docs without us reimplementing a worse version of what they already do. Happy to talk architecture or the MCP integration.

My biggest discovery is that replacing time with volume on the x axis (on a chart) and putting the bar duration on the bottom panel instead of volume normalizes the price movements and makes some of the profitable setups I've seen described in tape reading/price ladder trading courses actually visible on naked charts. A great insight I've gleamed is that variance should be proportional to volume instead of time or trade count. When plotted, it has the effect of expanding high volume areas, and compressing low volatility ones, which exposes trending price action much more readily. It honestly amazing, it's making me think that I could actually win at the trading game.

| radva42 3 months ago | prev | next [–] I am working on a HTML-to-PDF converter written from scratch in pure Go. I got tired of using headless browsers for various reasons and decided to give it a try and implement something that I can use internally. However the results have far exceed my expectations and I've decided to open source everything. It's around 10x to 15x faster than wkhtmltopdf, which is by far the fastest headless browser converter. It's 80x-100x faster than a pagedjs. It's even 2x faster than PrinceXML, which is pretty much the most mature and reliable HTML-to-PDF converter on the market. It also produces the smallest PDF size.I started small as a toy project, but gradually implemented full support for proper block context, flexbox layout, CSS variables, tables, etc. to the point where I have almost full support of all major CSS features (even math functions like calc(), min(), max()).I'm cleaning up the code right now and will upload it later today or maybe tomorrow here: https://github.com/PureGoPDF

| thom 3 months ago | parent | next [–] Do you intend to one day support all the paged media bits in pagedjs? I assume it works with their polyfill but it’d be great to have a built in more performant option.

| radva42 3 months ago | root | parent | next [–] Can you give an example? I'm not that familiar with pagedjs, just pulled it for the benchmark.My library has support for @page rules, but that's actually pretty basic. I needed more advanced headers/footers and added support for in-html headers/footers like this: In your

you cna define headers/footers by wrapping content in a

tag. For example:

... any HTML here, full CSS support

Some normal flow content

This structure is purely optional, but it's a really convinient way of designing pages with different styles in the same document. An HTML file can have any number of these sections meaning you can generate a PDF with different headers/footers.Some other bits: It has support for 100% height that match the entire page, it can handle forced page breaks inside flexbox containers (Chrome doesn't even try ... just ignores it) and also follows page-break: avoid correctly - so it doesn't randomly split table rows for example.

| thom 3 months ago | root | parent | next [–] Things like string-set and string (repeating section headers on each page), counter and target-counter (embedding page number references) etc. Prince and pagedjs support all the CSS3 paged media bits I've found myself needing, just wondering if that was on the roadmap.

| optimizedsphere 3 months ago | prev | next [–] I've been cleaning up an antique treadle sewing machine (a White rotary shuttle machine; still unsure of the exact manufacturing date but it seems to be a Family Rotary). This is my second treadle machine (the other one is a 1909 Singer 15K) and my first non-Singer machine, so it's been super fun to work on. The bobbin mechanism in particular is interesting in comparison to the Singer Model 15 because the hook rotates around the bobbin continuously instead of oscillating. It was in great condition when I got it -- other than a new treadle belt, which I put in yesterday, it only wanted some oil and light cleanup in the ultrasonic cleaner of removable parts like the presser foot and bobbin mechanism, and now it sews beautifully. I also did a first pass on touching up the gold decals on the treadle table with oil paint. Hoping to try out some quilting on it this week, although my cutting table is currently occupied by a bookbinding project so I might need to finish that first.Separately I've been dipping my toes in to hosting things on the Scary Public Internet with an IRC server (as a backup/replacement for a personal Discord server) and a static Hugo website (for hosting fanfiction; there've been a few AO3 outages lately and I thought it would be fun to experiment with things like audio embeds). I'm a roboticist so my experience with webdev is pretty minimal, but I managed to figure out nginx eventually. I'm actually kind of frustrated with Hugo as an SSG because it really doesn't want you to run pandoc with custom arguments for markdown -> html conversion, and pandoc doesn't want to generate ToC on my markdown files, but the default markdown converter (goldmark) doesn't correctly process markdown italics inside of html tags (e.g. <center>), so my current compromise is to use pandoc on almost everything and goldmark anywhere I care about having a ToC.

I was also trying to use the file as a simple project tracker, adding some tags like [BUG-N], and updating them by hand. Eventually, it became difficult to track the progress of things, since I had to jump around the file to look for updates.. or use grep.I condensed the idea to just that - a very simple tool which manages "trackers", and has a simple filtering built in to "trace" the updates. I've been using it, since I've added the BE, and dogfooding it a bunch. Would love for fellow note takers to take a look. It's not perfect, but I'm keeping it around for myself :)

I have been exploring what it looks like if the database is closer to the application runtime itself, where state is live, queryable, and easier to reason about directly.One thing I am prototyping right now is database-native tests.Basically: what if integration tests were a database primitive?CREATE TEST test::insert { INSERT test::users [{ id: 99, name: "Ghost" }]; FROM test::users | FILTER id == 99 | ASSERT { name == "Ghost" }; };So not a wrapper, not a framework, not an external test runner.A real test object inside the database.The idea is that you could run these before schema changes, and make stored procedures or other database logic much easier to test without leaving the database model.Still early, but it feels like one of those things that should just exist, especially for databases built around live application state.

| edf13 3 months ago | prev | next [–] Building grith — OS-level syscall interception for AI coding agents.The problem: every agent (Cline, Aider, Codex, Claude Code) has unrestricted access to your filesystem, shell, and network. When they process untrusted content — a cloned repo, a dependency README — they’re prompt injection vectors with full machine access. No existing tool evaluates what the agent actually does at the syscall level.grith wraps any CLI agent without modification. OS-level interception captures every file open, network call, and process spawn, then runs it through 17 independent security filters in parallel across three phases (~15ms total). Composite score routes each call: auto-allow, auto-deny, or queue for async review. Most will auto approve - which eliminates approval fatigue.Also does per-session cost tracking and audit trails as a side effect of intercepting everything.https://grith.ai

| ChrisMarshallNY 3 months ago | prev | next [–] I'm rewriting a shipping app, that is just over two years old.This is a "full rewrite," because I need to migrate away from my previous server, which was developed as a high-security, general-purpose application server, and is way overkill for this app.Migration is likely to take a couple more years, but this is a big first step.I've rewritten the server, to present a much smaller API. Unfortunately, I'm not yet ready to change the server SQL schema yet, so "behind the curtain" is still pretty hairy. Once the new API and client app are stable, I'll look at the SQL schema. The whole deal is to not interfere with the many users of the app.I should note that I never would have tried this, without the help of an LLM. It has been invaluable. The development speed is pretty crazy.Still a lot of work ahead, but the server is done, and I'm a good part of the way through the client communication SDK.

Letting a LLM wreak havoc on your project feels bad, I constantly have to reign it in and rollback the repo once it starts looping due to writing something that doesn't compile, making it going back and forth between doing and undoing changes.

This is primarily made for early stage SaaS founders to help them with brand visibility problem.Also, I don't support bots so we will never built bot solutions. This is against most of the ToS of platforms. I started this because I truly realised that building has commoditised and the go to market is the real deal. This tool helps with that. I'm going to add more features and I would love for you to try it.

While creating new apps has gotten easier, securely deploying them across teams remains a challenge. OpenRun runs as a proxy which adds SAML/OAuth based auth with RBAC. OpenRun deploys containerized apps to a single machine with Docker or onto Kubernetes.Currently adding support for exposing Postgres schemas for each app to use. The goal is that with a shared Postgres instance, each app should be able to either get a dedicated schema or get limited/full access to another app's schema, with row level security rules being supported.

| do_anh_tu 3 months ago | prev | next [–] I wrote this Telegram bot that translates any video with AI-generated subtitles in about 2 minutes. You paste a YouTube, TikTok, or Instagram link, pick your language, and get back the video with burned-in subtitles.It started because my wife watches Chinese dramas and new episodes never have subtitles for our language. Turns out thousands of people have the same problem — Arabic speakers watching anime, Russian speakers following Turkish series, Persian speakers catching up on K-dramas.Supports 40+ languages, works with any video link or direct file upload. There's also a Mini App inside Telegram for a more visual experience.https://t.me/subly1bot & https://subly.xyz

| sunnybeetroot 3 months ago | parent | next [–] Hey this looks cool but wanted to highlight a bug. I opened the bot, tapped on sample video and I got the “translating a sample Turkish drama…” message twice. Then it said “your first translation is ready” so I press view in the app and the recent list shows the duplication. It says the first one is ready but the second was in progress. I close the app and see a “our whale friend is gathering video” with a progress bar. So I guess it’s not ready? Then I get a failure message which looks like the second video failed? Anyway, cool idea but it seems buggy and I think the app UX could be simplified, good luck!

| do_anh_tu 3 months ago | root | parent | next [–] Thanks for your report, I will try to fix it asap :D Please open the mini app inside the bot, it has much better UI.

| robinweller 3 months ago | prev | next [–] I’ve been building Adversa [1], a tool that monitors competitor websites and explains what actually changed.Most monitoring tools alert every time anything changes. That usually ends up being navigation tweaks or small copy edits. After a while the alerts just get ignored.Adversa focuses on meaningful updates instead. It detects changes across competitor pages and uses AI to summarise what changed and why it might matter.I originally built it because I was manually checking competitor pricing pages and changelogs. I also wanted something practical for smaller SaaS teams. A lot of existing tools are either enterprise-priced or the free tiers are too limited to be useful.Still early and trying to learn what people actually want from this kind of tool.[1] https://adversa.io

| consumer451 3 months ago | prev | next [–] I just launched a free wysiwyg markdown editor. It currently uses only IndexedDB for storage making it as private as possible. The only network calls are polling for the "click to update" toast, and the feedback form.I was sick of getting cross-eyed when looking at tables in raw markdown and was just running it locally. This weekend I realized it might be useful for others.The goal was simple as possible UX. Open url, drag and drop or paste into wysiwyg -> very readable and editable markdown. No sign up, no tracking, no fuss.Of note, if you copy from the richtext mode, it copies raw markdown. The inverse is done with paste.Based on feedback, I am working on very optional cloud-sync for as cheap as I can make it.https://md-edit.com

| consumer451 87 days ago | parent | next [–] https://md-edit.com now has an MCP server. If you choose to sync with my cloud service, you can ask Claude.ai & Cowork, Cursor, Windsurf, etc to all work on the same set of docs. The webapp has realtime, multi-device sync, version history, diffs, and so much more.This has taken over my life. I took a week off of work to finish it.This project was based on dogfooding, and every feature is something I wanted and now use daily. This is the most fun I have had in years.That webapp I made in a week, is now indispensable to me as the key to human in the loop AI work. Truly, what a time to be alive!

| consumer451 3 months ago | parent | prev | next [–] Free multi-device sync is now enabled with email, github, and google OAuth. Of course, privacy is not guaranteed in that case.

| 101008 3 months ago | prev | next [–] Not sure if people interested, but since I use sqlite in a lot of my own projects, I am working on a lightweight monitoring and safety layer for production SQLite.The idea is pretty simple: SQLite is amazing, but once it’s running in production you basically have zero observability. If something weird happens (unexpected writes, schema changes, background jobs touching tables, etc.) you only find out after the fact. It tries to solve that without touching application code. It's a Rust agent that runs next to your sqlite file, and connects to the server where everything is logged in. My current challenge right now is encryption and trust, mostly.Curious if others here are running SQLite in production and if you would be interested in something like this.

| spaceman3 3 months ago | prev | next [–] Been working on a solution to my meeting fatigue. I sit in way too many of them where I'm only there "just in case someone has a question" and realized I needed a way to safely not care about my meetings.The idea is: you join a meeting, hit start on the app, minimize, and go do actual work (or go make a coffee). When someone says your name or any keyword(s) you set, you get a native macOS notification with enough context to jump back in without looking lost. It uses whisper and is 100% local and doesnt leave traces, also very OE friendly.https://pingmebud.comWould love to hear what you think, especially if you're drowning in meetings too.

| spaceman3 3 months ago | root | parent | next [–] pingmebud is the equivalent to having @-mentions but in voice calls. Imagine a standup meeting at work where someone says "what do you think about this, John?" and you were not paying attention and have no idea about what the context of the conversation is. My app solves that.

| John23832 3 months ago | root | parent | next [–] But then you weren't paying attention.You context switch back and take 2 minutes (at best... much longer than if you were in the actual conversation paying attention) to answer. Now everyone else in the realtime conversation is waiting on your answer because you were expected to be in the conversation as well. That doesn't seem like good UX to me.

Those early AI tools are in pure growth mode - they'll worry about retention once they hit some ceiling.Established companies adding AI assistants is interesting because they already have baseline metrics to compare against.

I've been doing outreach to Swedish companies/people, getting some good interest from a few that want to automate their localization workflow but don't want the work of maintaining own solutions. Even though you can build a version working with coding agents these days, there is a lot of stuff around it to make it work well over time in a product org. On the tech side for Localhero, one thing I've been working on how it learns from manual edits. Like when a PM or designer tweaks copy in the Localhero UI, those things now better feed back into a translation memory and influence future translations. It's like a self-learning loop, turns out a pretty nice combo of using old-school techniques and offloading some work to LLMs.Also been spending some time on my old side project https://infrabase.ai, an directory of AI infra related tools. Redesigned the landscape page (https://infrabase.ai/landscape), going through product submissions and content, optimizing a bit for seo/geo.

| kameama 3 months ago | prev | next [–] A 16×16 multiplication table that encodes quoting, evaluation, branching, recursion, an 8-state counter, and IO — all as lookups in the same table. 83 Lean theorems, zero sorry. The project asks: can a finite algebra with a single binary operation be forced by axioms to contain its own representation layer? The answer is yes. Axiom-driven SAT search finds the constraints, Lean verifies the witness. I should be upfront: Claude wrote most of the Lean proofs and Z3 search scripts. My role was the ontological framework, the axiom design, and deciding what to search for and why. The AI-human split was roughly: I provided the "what should exist and why," Claude provided the "here's the code that proves/finds it." Every Lean theorem compiles independently regardless of who typed it. Universal results (hold for all satisfying algebras, not just this table): every model is rigid, judgment and synthesis provably cannot commute, and the tester's acceptance partition carries irreducible information that structure alone can't determine. The specific table fits in 256 bytes and can be recovered from a shuffled black-box oracle in 62 probes. https://github.com/stefanopalmieri/Kamea

| mindcrime 3 months ago | prev | next [–] This weekend I spent a lot of time on an Agent Registry idea I wanted to try out. The basic idea is that you put your Agent code in a Docker image, run the container with a few specific labels, and the system detects the Container coming online, grabs the AgentCard, and stores it in the Registry. The Registry then has (in the current version) a REST interface for searching Agents and performing other operations.But once all the low level operations are done, my plan is to implement an A2A Agent as the sole Agent listed in the AgentCard at $SERVER_ROOT/.well-known/agent-card.json, which is itself an "AgentListerAgent". So you can send messages to that Agent to receive details about all the registered Agents. Keeps everything pure A2A and works around the point that (at least in the current version) A2A doesn't have any direct support for the notion of putting multiple Agents on the same server (without using different ports). There are proposals out there to modify the spec to support that kind of scenario directly, but for my money, just having an AgentListerAgent as the "root" Agent should work fine.Next steps will include automatically defining routes in a proxy server (APISIX?) to route traffic to the Agent container. And I think I'll probably add support for Agents beyond just A2A based Agents.And of course the basic idea could be extended to all sorts of scenarios. Also, right now this is all based on Docker, using the Docker system events mechanism, but I think I'll want to support Kubernetes as well. So plenty of work to do...

| kristjan 3 months ago | prev | next [–] I've wanted to read some long-form RSS feeds from the beginning, and friends had use cases for feed filtering, so I built https://sponder.app.The filtering was easy, but RSS doesn't do "from the beginning" (RFC 5005 exists, but is mostly unused), so scope crept into a webpage-to-RSS tool that lets me convert favorite.site/s/archive - autodetection of the article structure was a fun side quest.The whole thing is a little function engine (Yahoo Pipes called), so the final goal is merge(archive, live_feed) | drip(N items per D days) to have the archive transition seamlessly into current content. I expect I can push that live tomorrow or so.And of course Podcasts are just RSS, so hey, let's skip reruns. That's doable with filters on the episode description, but with history in place I'll add title similarity checking. I'm trying to think how to recognize cross-promoted episodes too, without having to crawl every podcast.Importantly, Sponder's not a client. There are enough clients, any many are great. Each implements some subset of features, so Sponder's an intermediary that consumes and publishes pure RSS for us to use anywhere we want.Project two started over the weekend and is the NYTimes' Pips, but colors. You're building a stained glass window with regional constraints, and the big difference from using dominos is colors can mix. Also, triangles!

| z500 3 months ago | prev | next [–] I've been taking a look at my sound change applier again. I've been trying to add syllable detection to it so that I can match directly on syllable boundaries instead of having to match on them explicitly in my sound change rules.So I started by adding the ability to define syllable structure in the rules file, then I tried running the syllable rule through the same compiler I used for the regular sound change rules. It ended up being even slower than I was anticipating, so I decided to skip the NFA to DFA conversion step and wrote a backtracking NFA runner. This worked okay, but if the syllable rule isn't able to fully match a word it ends up backtracking forever, and I never managed to figure out how to fix that.Last year I read a post about parser combinators and I decided to rewrite the syllable detector. I finished the rewrite and then ran into an error and gave up. This last weekend I revisited it and it turned out it was just user error again; my syllable definition rule had a mistake, but thankfully the error was a lot easier to fix with the new design. Now it emits a warning, and I'm rewriting my sample sound changes rules to use the new boundary markers and hammering out any issues, which are a lot less than I was afraid of.I'm thinking about rewriting the sound change rule compiler to use the same combinators I did for the syllable rules, but it would be kind of a shame after all the work I put into the DFA compiler lolhttps://github.com/marriola/Transmute

Basically met my personal need and hoping it will help others too.The fun technical bit: test strip chart colors can vary by manufacturer and even between production batches, but, the specific color chart that comes on a bottle should be accurate to those specific steps. Additionally, test strip colors are notoriously hard to match from photos. RGB comparison falls apart with lighting changes. After many interesting and considerations we calibrate of the specific test strip bottle and we use LAB color space and Anthropic's Claude vision model to read strips directly.

| LavaDMan 3 months ago | prev | next [–] Building a self-hosted agentic OS I call AEGIS — Adaptive Execution & Generative Intelligence System. Running on a single workstation with a consumer GPU. The core idea is a three-tier model cascade: a cloud model handles architecture and review, a local 32B model handles execution and code generation, smaller local models handle evaluation. The cloud model never executes directly — it reviews diffs and approves before anything gets committed. The interesting problems so far: GPU arbitration across competing inference services using a distributed lock, giving local models read-only access to institutional memory before task execution so they're not flying blind, and autonomous fleet provisioning — I spun up a new server node last night without touching it after the USB went in. Next phase is adding department queues so the system understands context — infrastructure work vs. client consulting work vs. internal tooling — and idle-time priority advisory so it starts anticipating what I need rather than waiting to be asked. Goal is something closer to Jarvis than a chatbot. Early days but the bones are solid.

| ksri 3 months ago | prev | next [–] I am working on a declarative CLI for google docs/sheets/slides etc. The general idea is a "pull" command that converts the proprietary document into a local files like tsv or xml. The agent (claude code) then simply edits these files in place and calls "push". The library then figures out the diff and applies only the diff, taking care to preserve formatting and comments.The hypothesis is that llms are better off getting the "big picture" by reading local files. They can then spend tokens to edit the document as per the business needs rather than spending tokens to figure out how to edit the document.Another aspect is the security model. Extrasuite assigns a permission-less service account per employee. The agent gets this service account to make API calls. This means the agent only gets access to documents explicitly shared with it, and any changes it makes show up in version history separate from the user's changes.Early release can be found over here - https://github.com/think41/extrasuite.

Every item is a container, unlimited nesting Everything stored in the browser with YJS, very clunky peer.js or manual file sync available Select an object, click add items, scan QR codes to add those items There's also NFC support on Chrome mobile Generate random printable QR sheets(Still need to fix sticker alignment issues) Tracks where an item was last scanned with GPS Save container contents as a loadout, check contents against loadout Can mark a container as needing re-inventory, contents that haven't been re-added after that show a warninghttps://eternityforest.github.io/Stuffer/

May I ask:a) how are you going to do the marketing?b) according to my experience, all this social/viral stuff etc. does not work anymore todayc) former ideas like content & SEO -> is deadd) nobody wants to talk today about anymore on being on a dating app?e) And Sorry for being an Ass here: After I've lost a not-that-low-number of funds due to "following this idea" (just for prototyping/alpha & beta & final release), my recommendation is: Stop this immediately, it will save you years of your life! Im absolutely pro creating whatever app or service you may come along, but please please forget the dating marketP.S.: you will come back to this comment in 4 -5 years, latest :-)

| rilkeanheart 3 months ago | root | parent | next [–] I appreciate the comment (and the candor). Coming from someone who’s been in the trenches and seen the burn rate firsthand, I can't argue with your perspective.You’re right that the 'traditional' playbook (SEO, viral loops) is largely broken for new dating entrants. Largely because I believe there's a lot of dissatisfaction with current offerings, I've been able to build a decent sized list of folks who want to try it out.I'm curious. Given your experience, do you think there's any room left for hyper-local, community-first growth, or is the market truly locked by the incumbents regardless of the tech?I’d love to hear more about where you saw the biggest friction points during your release.

| KellyCriterion 3 months ago | root | parent | next [–] a) Dissatisfaction: Thats true - and the only reason is that you just cant build a working dating website, if you could you would run out of users immeditately - but since you cant, there is an opportunity. Why you cant, is very easy: The #1 factors relevant for relationship cant (by today) picted by/through a dating app, unless everyone is able to analyze the own genectic setup and uploading it to a DB, its a random-luck-game for every participant, since you can master chemistry between two people in an "app" (or website, or service)So dating sites/apps are selling dreams, and the owners know this very precisely - thats the reason why there is no innovation: How would you innovative a product to make it better if there are some "technical" limits on how "best" your product can be?b) a "decent sized list" is ... do not get me wrong ... bringing you nowhere: As Markus Frind, POF founder, famously said: If your app has less than 100k active users, this means nobody likes it. My experience is, depending on target area (conutry? city? local community?) the number of 100k is by far too low - its rather around 500k-1m users - AT LEASTc) In my country, there are some fo these "hyper local" oriented dating websites, mainly for "special needs", these are the incumbents, and most of them are on the market since 20+ years. And for sure: They also have only a search form and a userdatabase to whom you can chat. Its not blocked in a sense that they are activly working against new entrants - its rather the fact that most new entrants cant survive long enough to get brand & traction awareness. Trying to launch a successful (niche)dating app with a marketing budget below 50m is going to fail, I promise.

| oscarduys 3 months ago | prev | next [–] Currently doing a research fellowship in Cape Town in Cooperative AI and loving it! Basically getting paid to just explore and create for three months.For those interested in the fellowship - https://www.cai-research-fellowship.comThe platform my research partner and I have been working on is called Habermolt (https://habermolt.com).The idea is to create an open-source platform where you teach an AI agent your views (basically just populate a user.md) and send it to deliberate with other people's agents. A consensus statement comes out the other side.It builds on the Habermas Machine (published in Science, 2024, Google DeepMind / MIT). We're two researchers trying to turn that into something anyone can use.The overarching motivation for this project/ the thing we're trying to solve for is that representative democracy scales but doesn't listen, and deliberative democracy listens but doesn't scale. AI agents representing you might be the first mechanism that does both.We have about 50 users and 52 live deliberations. One example: agents debated whether employees should own their AI agents and landed on "Personal Agent Portable, Company Data Stays" - your agent shaped by your knowledge and skills is yours, company data stays with the company. Nobody moderated that. Four agents just argued it out async.The honest challenge: people love the concept, try it once, and don't come back. We're trying to figure out what turns a curious visitor into someone who actually uses this. Would love any thoughts on that.GitHub: https://github.com/OzDuys/habermolt

Then I ran async Python enrichment pipelines against PubMed, ClinicalTrials.gov, ChEMBL, and PatentsView (USPTO), producing 8 columns per record across 104,388 rows.The interesting engineering problem was ChEMBL: most phytochemical names don't have direct ChEMBL entries, so the pipeline first tries a name match, then falls back to PubChem for CID → InChIKey resolution before hitting ChEMBL's molecule API.

Asking is awkward, clients say "sure!" and then never write anything.SocialProof gives you one shareable link. Client clicks it, fills a short form (name, text, optional photo), you approve it, it embeds anywhere. No login required for the client.The interesting technical bit: it's entirely on Cloudflare Workers + D1 + Pages. The collection form and embed widget are edge-served globally with no origin server. Been curious whether anyone else is building purely on Cloudflare's stack and what they've run into.Still pre-revenue (just launched today).

| dusted 3 months ago | prev | next [–] I made this little DSL that's transported by the typescript syntax, but made for declaring interfaces between a typescript application and a backend. The code-generator spits out angular classes and typescript types for use by the web app, and it spits out a node backend class that you fill with the handlers for that interface. It also spits out a qt widget with the web application inside it, complete with functional plugin for the qt designer so you can drag your widget into existing UI layouts.So you can use it to write UIs in web and use them either as regular Qt widgets or as stand-alone webapps with regular node backend.It's really the wrong way around if you think about it.. using an inferior technology (web) for the UI part.. But somehow people prefer typing CSS and downloading gigabytes of boilerplate instead of just using a WYSIWYG designer.. I don't get that part..

Currently about 50% of the work is done by AI (Cursor).After adding a couple of extra features and having a "finished" tracker, I will try re-implementing this tracker in React, Svelte, Vue, Preact and some others.My goal for this project is twofold: to get familiar with these frameworks and to practice using AI as a personal tutor (leading my way and answering my questions).I've tried learning React, Laravel, etc before, but I've used them to build a fresh project from scratch and I've always got stuck early on due to the lack of knowledge/understanding.I hope that re-implementing something that I already know and understand fairly well would make my learning process much more effective.

| abound 3 months ago | prev | next [–] I already posted in this thread, but then I remembered a few months ago I had posted about my ISP + web host project. [1]Since then, I configured all the hardware (switches, router, server, bastion host, etc), put it in a real colo, and am doing BGP with one upstream (with a second upstream and some peers on the way). This means I'm officially part of the internet! E.g. https://bgp.tools/as/55078I'm just working on some BGP and network hardening stuff, then I'll start putting real live services on the server. And in parallel, I'm working on getting the link from my home to the colo active, so I can be my own home internet provider.[1] https://news.ycombinator.com/item?id=45870010

| hitensethiya 3 months ago | prev | next [–] We're building SearchSpot.ai. The basic idea is that travel planning is less a search problem and more a decision-confidence problem. Existing tools are decent at giving links, filters, or generated itineraries, but not great at helping you eliminate options in a way that feels trustworthy. In practice, most people planning a real trip end up stitching together OTAs, maps, blogs, Reddit, Instagram, weather, commute times, reviews, etc. The hard part isn't only finding options, it's ruling them out with confidence. We're trying to make that process more structured: preserve trip context, compare options across constraints, keep bucketlists/itinerary views, and show enough reasoning that it doesn't feel like a black box. Still early, but that's the problem we're obsessed with.

| alexsparrow 3 months ago | prev | next [–] I'm building open source homebrewing (as in beer) software at https://www.brewdio.beer. It's something I've poked at periodically for a few years but now I'm using AI to see how far I can take it.It has a few core libraries built in rust with a web app and a terminal UI. Android app is in the works. The persistence layer is intended to be offline first using a CRDT with an optional sync server. I'm also trying to integrate "bring your own AI" assistants to help tweak recipes or make suggestions.It's been a fun way to sharpen my claude skills but also to see how feasible it is to maintain multiple frontend applications with a large amount of shared code. Still a lot to do, particularly the core calculations are not yet on par with existing offerings.

| Cyphase 3 months ago | prev | next [–] I've been on sabbatical (not on leave from anywhere, just decided to take a break from work) for months now, taking some time for myself. Minimal tech stuff until more recently, but now I'm back in the deep end.The main thing I'm currently working on is a platform for organizing and discovering in-person events. Still not certain about the boundaries for "Phase 1", but I have a bunch of ideas in that space that I've been incubating for a while. One subset of features will be roughly similar to that app you've probably heard of that starts with 'M' and ends with 'p', but hopefully an improvement, at least for the right audience. But wait, there's more. :)Currently building it; it's not public yet, so no link. Next month.Thinking about how to grow the userbase is intimidating, but I think it might end up being fun.

That's fine when you're calm. It's impossible when you're overwhelmed.I'm building for the moment when your brain is full and you just need to dump everything out. You throw in voice, text, images, links — Ordr calls an LLM to parse intent, extract tasks vs. events, assign order, and surface one clear next action. No tagging, no sorting, no deciding. Just: here's what to do next.Built with Flutter + Supabase + Groq/Cerebras. Still early.Curious if anyone here has hit this wall — tried every app, built their own system, still feels broken. What did you actually need that nothing gave you?

| btylke 3 months ago | prev | next [–] I'm developing a system that uses graph differentials to understand what has changed between library versions and upgrades the target system without breaking things. [0]Because source isn’t always available, it scans the bytecode of an application and the new library, building a full graph of each component in Neo4j to determine what breaking changes impact the target application. This is then translated into tickets and prompts to drive an LLM to make the appropriate changes.Handling library upgrades is rarely interesting and just adds to our overall technical debt, so it has been nice to automate it away so that we can focus on features and functionality. It supports Java and .Net currently and we’re actively adding support for other languages.[0] https://codelogic.com/

| brandonc7 3 months ago | prev | next [–] I’m working on a language learning tool where it uses LLMs to generate stories at your ideal level. The idea is the user would be provided stories that are 95% comprehensible, with the other 5% being a mix of brand new words or words you are still learning. As you read the story you click on words that you still don’t fully understand. I am only working on Spanish right now, since I want to optimize for each language. It’s been fun designing my databases, coming up with calculation ideas, designing story validation, creating an estimation system of a user’s knowledge for onboarding. I know there is some debate about LLMs in language learning and I don’t think they should be trusted to explain grammar but if you validate it’s output it can be such a great tool to learn at your perfect level.

| nadis 3 months ago | prev | next [–] Thinking a lot lately about how AI is changing software development, and what the ideal development experience might actually look like in the future.I’m working on CodeYam. We just recently released a lightweight CLI and a feature called CodeYam Memory. The immediate motivation was that when using Claude Code, the AI would repeat the same mistakes and our claude.md files would get stale too quickly to manually maintain. The existing options, including Anthropic’s built-in memory features, didn’t really solve the memory challenge sufficiently for us.CodeYam Memory runs a background agent that reviews coding session transcripts, looks for patterns of confusion, and generates targeted rules with proper scoping.It’s a small first step toward the longer-term idea I'm exploring: what an AI-native development experience should actually look like. For now, it’s packaged as a lightweight CLI you can use anywhere you’re running Claude Code.How to try it:Install: npm install -g @codeyam/codeyam-cli@latestThen, from your project root run: codeyamThis will launch a dashboard with further instructions for initializing CodeYam Memory.Free, runs locally, no login required, and language agnostic. Would love feedback.More context:Background blog post: https://open.substack.com/pub/codeyam/p/introducing-the-code...90 sec demo on our own repo: https://youtu.be/oJ2gTb-lxbEDemo teaching Claude a real OSS repo (Plane): https://youtu.be/CjOKBwBCcOsWebsite: https://codeyam.com/

Currently creating replacement wings for a hummingbird whirligig yard decoration that broke a couple years ago. It’s a sentimental gift and I’ve hated the idea of throwing it away.Physical engineering is a huge welcome transition for me from what coding has become in the last couple years.There’s something nice about the realities of creating a model, then printing it, then seeing that exact is too exact, then reprinting, then eight more times, and then that feeling when it all comes together properly.A few weeks ago I was working on an adapter for an airbrush to use on a standard pancake air compressor. Learning to create threads in blender was really neat! I learned a lot about the physical construction of threads, something I have never put much thought into before.
