It's been really fun to build with. Agents can create parametric procedures so e.g. stick framing becomes a simple function call for the next agent, building a flywheel. There is full agent-human parity in every surface, so there is a human UI for the procedures too.
Every operation is yaml, so agents pick it up pretty quickly. Agents can also file feature requests when they reach for a tool that doesn't exist. You can export to 3d printing files, video walk-through, step files, get a BOM and a cut plan, view your project in life-size with AR. There is a notion-like interface for authoring build guides... a lot going on. If you're a woodworker/software engineer you might enjoy it.
You can add the MCP to your agent of choice, send a picture, description, sketch or whatever; say "build this with Sawdust"
https://sawdust.diy
I wanted to build a bed frame recently and imagined software where I could choose lumber from a list and visually assemble the bed frame in the software how I see fit, choose stains, flourishes - then go order the wood and have it cut. At that point it's like taking home an IKEA bed, except of way higher quality materials and to your exact design spec.
So
> Real SKUs, a real BOM you can send to any lumberyard; understand exactly what you need down to the last nail.
Is especially interesting, it sounds like you could basically do that with this software.
Turning the woodworking process into code to be automated by an LLM is pretty ambitious, and is the part I am most skeptical about. Of course, if you get that right (plus adoption) it would be unbelievably huge.
And you can customize it beyond the existing design by asking an agent to modify it, e.g. "let's use walnut 4x4s and 2x4 slats", "I don't like how the corners come together, can we make it more like traditional joinery?" Also, staining is a supported procedure (it's very useful for e.g. coloring geodesic dome struts by strut type), you can just ask the agent to stain the pieces with whichever color you like, I'm sure you could even use a named stain you want to use like "Minwax Dark Oak" and get something pretty close.
Impressive stuff. Actually more impressive than I even imagined.
“Fits in my SUV” you are a mad man! Love everything about this site. I might actually do it now haha - no more excuses.
I also suspect there’s a fairly finite number of sane join primitives, you can have rabbets, dados, dominos, dovetails, pocket screws, etc. These could be experimented with digitally against an existing design. And your tool availability could determine what you can do.
And of course cut order and assembly is just a DAG and can be generated from geometric constraints of the actual design.

Feel free to reach out! Email in profile.
This was all pre AI. Super impressive that you’ve made something awesome. I’ll try it out tonight
I keep seeing this word. Every time, I have to look it up; I marvel at the fact that we have such a cool word describing a complex but interesting topic; and apparently forget it again. And then I never find a situation where I can use it.
If this does what I think it does (and I confess I’m a goddamn idiot still when it comes to anything involving ‘agentic’) this is honestly pretty damn amazing.
It's a PWA, not a native app over at https://fringeflypost.com/ (or you can go directly to https://fringeflypost.com/shows to browse if you don't want to make an account.)
Try it out: https://github.com/preloopdev/preloop
https://www.idlequest.net/ - a from-scratch recreation of the 1999 MMORPG classic EverQuest, featuring a real-time MMO server written in Go, a 3D game browser-based client built with Babylon.js, and the clasic UI recreated using React. You can play it both as a regular MMORPG but also in "idle mode" where it basically plays itself. This had up to 70 players online at once a while back which was really cool, though its popularity is in a bit of a lull right now. There are still tons of bugs and stuff that isn't fully implemented (and balance issues) but it's still fun for most people who have nostalgia for it.
https://www.newyokosuka.com/ - an unofficial Shenmue MMO experience. Based on the 1999 Sega Dreamcast game Shenmue, it's playable entirely in your browser! It's basic world exploration with forklift shenanigans, some basic dialogue systems, and a basic combat system test, but I'm about to push an update that includes all cutscenes and story progression as well. The story part is taking a bit of time because I'm having to mold it to fit in an MMO context. But it's a fun project to work on and the Shenmue community loves it so far.
I've had people play IdleQuest on tablets and Steam Deck but I'm fairly certain it would be horrible on phones.
How is this not going to get sued into oblivion by Sega? Especially using your real name with it.
That being said, I tried it on Firefox and just got an empty blue screen after the level loaded.
I've overcome about a dozen "there's simply no way to do this in MacOS and I have to abandon the project" challenges so far. MacOS really does not want to let you manage windows in this novel of a way, and I've had to come up with a handful of tricks to maintain the illusion that the WM is accessing the compositor at a lower level than it actually is. But it works, and I'm dogfooding it as I go!
I'm hopefully only a few weeks away now from a full announcement and a beta. If you're curious to try the first beta, feel free to get in touch at clayton at presteign dot com.
I used to be a mechanic, and spend a lot of my free time working on project vehicles, motorcycles, tractors, trucks etc. I wanted a tool to track the tasks I needed done, then a way to easily access VIN info for parts search, then I DMV records, and finally built an iphone app to scan the OBD2 diagnostic codes and hook them up to a custom ai diagnostic prompt.
It's been a blast to work on, I need to focus on marketing it and get some users that aren't close friends, but it's been serving my purposes this summer so far.
I've seen nothing with anywhere close to this depth of diagnostic reporting.
https://crewchief.cc https://apps.apple.com/us/app/crewchief-auto/id6760673109
Where it is make-specific is the interpretation layer. The code database includes manufacturer-specific DTCs for the 10 major makes, and there's per-model data down to the generation level — known failure patterns, which codes are common on which engines. So a P0171 on an E46 gets read in the context of "this generation eats intake boots and DISA valves," not a generic lean-code writeup. The AI report is conditioned on the exact year/make/model/engine, which is where most of the diagnostic depth comes from.
That being said, I'm continually expanding support, it really just depends on what sort of barriers I run into with these bluetooth scanners. For certain types of diagnostics (large truck / Buses etc) I'll likely need to make a separate desktop app that connects directly wired.
- it is a collection of ~ 2700 temples across India, with images sourced from wikipedia
- it shows you a random temple each time you visit
- it has a map view of temples across India
So this is just the tip of the iceberg. I am trying to build a catalogue of all temples, starting with India, and expanding on to the rest of the world. The focus is on temples originating from Indic religions like Hinduism, Jainism and Buddhism.
I have personally discovered many cool temples that I have never heard of, but I am struggling on how to gamify this. Feedback welcome!
I was never much of a game developer, but recently my 5 year old son wanted to play a game so we decided to build one together.
It's a boat game, you basically steer a boat in an isometric 2d world, transporting passengers, cargo etc between ports.
As we designed it, the ideas just kept on coming. He made or directed a lot of the art inside of the game (even the audio), and we included friends and family as characters within the game.
A lot of fun to build - hilarious at times. I used Lua and LÖVE2D, building basically a game engine for an isometric world, so that took significantly more time than expected.
If you want to test it [1], please do, but keep in mind it's only in Norwegian, but I am sure most people would be able to figure it out as it's meant for age group 5 and up:
[1] https://apps.apple.com/no/app/b%C3%A5tspillet/id6791630382
At this point our entire extended family and their kids, grandchildren etc are actually playing this, so it's been super fun.
https://breaka.club/blog/why-were-building-clubs-for-kids
I also attempted to make a game with my eldest daughter initially. Unsurprisingly, she didn't want to sit there watching me code or drag things around in Godot's level editor.
Admittedly, I really need to make a new blog post showing the latest improvements brought about from the in school pilot I'm running weekly at the moment.
I started with Leptos - which gives you a nice declarative UI syntax and reactive elements. I used Claude to get that working on iOS, cocoa and GTK. I made a nice little iOS schedule app for attendees at conferences. It works great. All rust, native UI and a fast and small binary. The current UI code is here: https://github.com/josephg/leptos-native (not officially part of leptos). It works well, but not all of the components I want have been implemented.
At the moment I’m rewriting the core to ditch the vibe coded parts and break the whole thing into an app backend API and separate platform layer. I want to be able to write apps in wasm and have a windows / mac / Linux host that can run them using native UI. And a runner to run any app using a TUI. And have a compilation process to compile the whole thing into a single native process for app developers and to publish to the App Store.
https://github.com/josephg/dweb-sched
It's got full native calendar integration - so if you want you can favorite a session and it'll automatically add the session to your calendar in ios. (Or un-favorite to remove). It looks and feels completely native. I'm using taffy for layout - which is a pure native rust implementation of CSS's flexbox & grid layout engine. So layout works the same everywhere, using the same primitives you find in the browser.
The UI framework is still quite experimental though. I'm rewriting the core at the moment. The API won't stay the same for 1.0.
It's an automation game and factory builder with "falling sand" physics. Think Noita meets Factorio.
I also remember playing that Powder Toy game on my phone in grade school, and I have a ton of nostalgia for these kinds of physics.
Will there be significant hidden mechanics/riddles/lore built into the world in a Noita-like way, or is the physics engine the limit of that comparison?
How does such a deal work? Do they contact you? Or are there places where you can promote your game to get it on Game Pass?
It's my publisher (Hooded Horse) handling it so not sure about the exact process. I don't think it's easy to get a day 1 deal though so I'm very grateful for it.
Good luck on your game & launch!
I got depressed from my grievance with my abusive mother and started reading the compiler dragon book along with artificial intelligence by steve.
https://github.com/x64x2/proc
It started getting some search impressions and clicks, so I decided to launch the next 9 of the top 10 ideas that ChatGPT came up with for this type of site - won't post all of them here, but https://the-dwell.com/ (data on ship and truck dwell times/port congestion) is doing the best thus far from a traffic perspective.
First I had it send me a weekly analysis of the GA4/GSC data to see what could be improved about the site, but I've since automated that - each week it reviews traffic and search queries, then updates articles or creates new ones to meet demand. So now in theory I have a full engine to launch these sites and have them self-improve over time. Kinda neat to see all of that being done autonomously.
The thing that these sites really need are some backlinks, so I'm thinking through how to get those. I had ChatGPT generate some lists of places that might find real value in linking to these sorts of things, but I'm unwilling to let an AI agent start emailing people. I'm going to try sending some emails to some of the places that seem like a really good fit, see what the response is, and if it's good try to figure out how to do that on a larger scale without AI email spam.
But you're right that it'd make sense to have an aggregate view on the level above (e.g. https://the-dwell.com/anchored). I shall go command Fable to figure out all the places where this would be appropriate and add it.
https://store.steampowered.com/app/4564800/Dictatorship_Simu...
Parallelly, I'm working on an attention-based memory retrieval system that achieved SOTA on LongMemEval, LoCoMo, and code retrieval benchmarks. https://github.com/AttemorySystem/attemory/
Maybe later I'll build a live-streaming AI agent that plays Slay the Spire while conversing with viewers and remembering everything in chat!
What do you mean by agent in this context? Does it mean LLMs?
What search problem are you solving for deck building and is MCTS for combat the same as that in Go AIs?
I categorize the game's actions into three types: combat, deck-building, and other interactions.
For combat, MCTS is used. Yes, it's similar to the approach used in Go AI.
For deck-building, a sparse graph search is used: the goal is to rapidly identify winning deck templates within the graph structure.
Only the remaining aspects are delegated to the LLM to make reasoned decisions.
I really enjoy working on the app though. The backend is Elixir, with a Phoenix LiveView dashboard. I've got a cluster of 3 nodes running, talking to each other. The probes that check the monitoring targets are tiny go binaries, spread across hosting providers across the world. I've also got synthetic probes now, running in little playwright sandboxes.
A lot of the challenges have been around how to distribute work across the probes, with different strategies for the basic TCP/HTTP probes vs the synthetic workers, and how to effectively store large amounts of events (Clickhouse).
Which leads me to trying to get the processing off github actions (it's all duckdb pipelines), which has led me to improve the orchestration implementation of my 'better sql' [2] to optimize the asset based refresh flow. I'm now wiring that up in a general cloud service to give me the data orchestration platform I've always wanted. Building a multi-tenant cloud experience has been interesting!

You press ctrl+n and you get a sidebar showing all the tmux tabs you currently have and the statuses of the agents.
The sidebar then has a couple different navigation modes based on what floats your boat, toggle by tab:
1. Using vim bindings j/k, and supporting number -> j/k to go up or down quickly.
2. Using number -> number. Meaning you press the number of session then number of tab.
3. Using search, useful if you have a ton of sessions open.
I really like what herdr, cmux and others are doing in this space, but I find it hard to get myself away from my core tmux setup, so I made this to not have to change too much of how I work.
We will soon add more import conveniences, like asking your llm to generate importer for your special pdf formats. See https://finbodhi.com/changelog for details.
We also write about related topics:
We wrote about comparing investment options: https://finbodhi.com/docs/blog/compare-charts

I've been a bit obsessed with chess lately and have read/heard things like "X is the top engine move, but no one under master plays that line". To me this begs the questions "which line are players below master playing" and "which line are players at/above/below my rating playing". This question motivated me to build a tool to analyze the move distribution (win/draw/loss rate) from a given position across rating buckets (400, 500, 600... 3000). Luckily, https://database.lichess.org/ provides an open/free database of games that have just the data required to build such a tool.
The Rated Analysis tool consists of an 1) an offline job to compute/store the positional move distribution bucketed by rating, and 2) the https://rated-analysis.pickle-dev.com/ webpage to serve the data along with some nice to haves like loading user games from platforms like chess.com/lichess.org.
wireplug lets you create mesh VPNs using standard WireGuard. Your wg config files stay almost the same, except you no longer have to specify an `Endpoint` for your peers. Instead, wireplug detects all your possible endpoints (including LAN) and coordinates them with your peers for you. It handles NAT traversal and works with the in-kernel WireGuard driver on Linux and OpenBSD. This lets you keep managing your own keys and network topology, while also maintaining connectivity when moving between networks.
Currently working on improving NAT traversal by adding support for PCP and NAT-PMP.
I've worked on it for about a year, with 1700 commits. I've been going back and forth if I should just open up the canvas or also the multiplayer experience.
I've always had the dream to make some money from a side project, but I don't think this one is it, so I'll just make the entire repo public. Just want to clean up some stuff first.
Lots of fun tech used: duckDB WASM, Cloudflare Durable Objects, tldraw and pocketbase
If you just want to see what it looks like here's a demo looking at hackernews data: https://kavla.dev/hn
There's also no email verification gatekeeping it so feel free to just input some bogus data when signing up
Also looks like the table shapes broke, there should be data that you can browse and download. I've replaced those with screenshots just in case anyone else sees it
https://spicycircuits.dev/
For now, there's no backend and it's hosted on GitHub Pages; it's a static website reading chunks from an sqlite-based DB file. I intend to change it in the future by running an LLM (preferably a frontier Gemini model, as works great for Persian) over the whole data set so you won't need a key to read the translated poetry. However, I don't have the budget of $1000-$2000 to spend on the tokens currently.

P.S. Contributions welcome.
This probably sounds like a crazy question, but if you are already getting translations using someone else's API keys, can't you just store/cache that response so that the next time the translation is requested, you already have it?
The bet is that current models are good enough that anyone can one-shot a fun browser game. What they can't generate is the multiplayer part (server, WebSockets, state sync, hosting), so that's the only part we've built: a browser SDK plus a hosted relay. Deploy a game, get one link, and everyone who opens it is in the same room.
Quickest way to see it: open any game on https://antics.gg/games in two tabs.
https://feedbun.com - a browser extension that decodes food labels and recipes on any website for healthy eating, with science-backed research summaries and recommendations.
https://rizz.farm - a lead gen tool for Reddit that focuses on helping instead of selling, to build long-lasting organic traffic.
https://persumi.com - a blogging platform that turns articles into audio, and to showcase your different interests or "personas".
Took a long break earlier this year to recharge, but now I'm back at it again, mostly working on Feedbun, about to launch it as an early alpha. :)

You send it your events via email, online, in-app, or text message even, and it puts it into your calendar for you, letting you know if there’s conflicts and keeping track of who is assigned to what, not just who’s attending or not. My goal is to have it proactively notify you when there’s potential issues like rain, traffic, or something else.
You can connect it to ChatGPT, Claude, or other agent through MCP so you don’t even have to use the built-in AI. And there’s an API, SDK and CLI for those who want to tinker and build custom displays or interactions.
There’s an always-free version to get started and try it out. You can find it at https://mavolife.com
Done a lot of analysis, sliced and diced data different ways, and then realized I need a website.
Ended up building https://climbable.day - hopefully a helpful resource for fellow Mountaineers from Seattle and around. 500 summits, 20 years of weather data, then went all in and added
- Wildfire smoke map overlays from official sources - Road closures from WSDOT - Information about approaches to most of the summits, sourced from Peak Beggar and Mountaineers - Database of known incidents from AAC - Compare your plan A, plan B, plan C, that type of thing
Site gained traction in the local community, and I have about a couple hundred users that seem to be using it on a weekly basis. It's free, and I intended to keep it such. It's a personal project, not something I plan to make money on. If you're in PNW and find it helpful, I'd be happy to hear what ideas you have. If you're not in Seattle but would like me to extend it to cover your neck of the woods, let me know.
For example, here's my recent trip with few friends https://www.mountaineers.org/activities/trip-reports/interme... - 2 nights out, roped glacier travel, scrambling, rock climbing, a good mix of planning and stamina was required. And for all I know this is a low end of mountaineering.
A low-cost vibecoding website for non-developers. Still in alpha.
I just finished my master's in Psychedelics and Consciousness Studies, and built the library I wanted while studying. I started it over a year ago, but put it down until my practicum advisor suggested I dust it off and go hard on it during my last term.
As of this writing, there are over 35,700 papers by over 82,200 authors organized into 37 topics, growing daily. There's a 2D map of the whole corpus and evidence syntheses on the topic pages, plus the ability to generate your own syntheses with any prompt.
It's built with Rails 8.1, uses one Postgres (for full-text search, vectors, and job queue), and runs on a $24/mo DigitalOcean droplet that I just upgraded from the $12 tier and deploy to with Kamal. Total LLM spend so far is ~$28 in DeepSeek-V4-Flash, trending down after a big one-time backfill push.
Relevance was the hardest part to get right by far. Ensuring we keep papers on LSD the psychedelic vs Lumpy Skin Disease, or Ketamine for depression vs anesthesia in cats was no small feat. The design ended up being a cheap keyword prefilter, then an LLM rubric that accepts or rejects papers. More on that here: https://consciousnesslibrary.org/docs/article-pipeline.html
It's free, no ads, no signup to read anything, and a registered 501(c)(3) I fund myself for now. I'd really like to know what breaks or any other feedback, and would love to answer any questions about it!
That said, I've been working with Josie Kins who runs https://effectindex.com/ and she's been building out a new system that incorporates categorized subjective effects on psychedelics, dosage and harm reduction info, with a huge amount of trip reports from all over the internet that we'll integrate into the individual topics sections probably in the next couple months.
1) grounding LLM scripture references in the actual text and eliminating hallucinations. This is the platform for that. https://withlattice.com
2) how to use AI to get people into scripture more as opposed to being a substitute for it. This is the product I made for it - it uses #1 above. https://trysojourn.app
I’ve mentioned it before, but we can get some pretty good results for developing implementation and tests with this setup. The context isolation makes it easy to separate test and code writing using a specification as a source of truth. Tests are then run by an arbiter that feedback to tests or implementation depending on who it blames for test failures. The tests are then treated as an independent implementation, and through the math of coincident errors, the arbiter feedback loop ensures that both are eventually correct (N-versions and clean room research did this with humans in the 80s). This then allows us to use less reliable LLMs to develop code, like Qwen on a MacBook Pro.
I hope to have something out on GitHub before my beach period ends (well, if I’m unsuccessful in getting a new role, then I’ll have a lot more time to play at least).
Edit: ok I cheated using Gemini. Gardening leave is you are leaving or were terminated, and they have to pay your salary but don't want you near company assets. On the Beach is you are waiting for your next assignment and have access to training and such, you aren't consider a security breach.
I'm in both worlds right now: I wasn't technically terminated, so I can look for a new position (like being on the beach), BUT they think I'm a potential security breach so my access to corporate resources is really nerfed (like on gardening leave).
Gemini calls it being a "displaced employee". I like to think I'm just on the beach in Bali working on my own projects.
So, I'm building a compatibility layer; something that works with everything - including your own vibe-coded personal CRM.
It's already helping - even something as simple as correlating calendar events with new connections so that you always know where you met someone.
https://tend2thrive.com if you're curious; It's live, so DM me if you'd like an account rather than just hitting the waitlist.
Meanwhile, I decided to revive my Rust liblinux project. Rust has come a long way since 2019, notably the inline assembly macro has been stabilized. I will learn Rust this time!
This year, I am creating a nodejs MUD, well closer to a MUSH actually.
* Everything is an Entity with Attributes * A player is an Entity with its client property set * There's a handful of built-in commands, but the important ones are @eval and @set-attribute * The soft-code language is ... JavaScript. * It uses the vm module from nodejs[0] to execute stuff. * It has separate clients (so far) for Discord, Slack, and local console. It's easy to add more and will be easier after I do this one refactor.
Each time an soft-code command or function or what have you executes, it creates a new context to isolate the soft-code from the rest of the application and uses Proxy objects to isolate the database Entity from the soft-code Entity. As an example, this is the look command (placed on the global registry object):
The Proxy manages access to Entities and Attributes (for example, Attributes can only normally be accessed by their owners).The MUSH outputs markdown for everything, so each client can format it however it likes.
I know the security is not nearly close to perfect, but it's mostly a proof of concept that I will make public one day. I did do a few things, like disable eval and Function and Promise but there's probably plenty of ways to get around it.
Originally inspired by the stream deck, but I wanted a more dynamic interface and less hardware restrictions. For example you can use your phone as the controller.
Now it can do a whole lot more. Including mouse, keyboard, media controls. Supports custom buttons types and things like sliders and color pickers. Dynamically switches layout based on foreground app, and can also control which app is in the foreground from the controller itself. Having a lot of fun so there are a bunch more features in the hopper like deeper app integration, and an eink version.
Its a web app/PWA, so no app store needed.
As a small way of standing up to them I created https://rigove.co.uk/ (rightmove without htm - the hidden toll machine ;)
If you change rightmove to rigove while browsing a property for sale you get a page which shows where else that property is listed.
It is only a few days old so it is currently more miss than hit but I plan to reach out to estate agents to increase coverage as quick as I can.
I've also been slowly chipping away at a Jagged Alliance 2-like game in Godot. Nothing to share yet but if anyone else is also frustrated that there hasn't been a good video game since Jagged Alliance 2 and you want to work on it reach out to me through the contact in my profile.
Zero-subscriptions google + social media search mcp/api/dashboard/sdk.
Every $10 gets you 15K google searches + 3K Twitter search/lookups + 2K Reddit + 15K Url fetches as markdown for feeding to your llm's.
Your credits never expire, use them whenever you want to, and you can stack them as many as you want.
Already got 40+ paying customers within a month of launch.
Now trying to add more social media.

It has a few potentially interesting side effects:
- enterprises can plug their preferred LLM into the SaaS they use.
- self hosters can extend their rigs into the web.
- simple SaaS products can offer LLM integrations without their entire pricing model being upended by LLM hosting and infrastructure.
- we can all live like Ender in Xenocide and have a personal AI that has context on everything we are doing.
- have a no op provider for people who are anti llm.
I decided to make my own version of the state parks website which surfaces precisely what you need for all parks in one place and make it filterable. I've been adding states and features to it for the last month or so and I'm up to 20 states and 1252 parks.
I try to keep each parks' fire bans, alerts, and events updated on a cadence.

I've been pulling a bunch of stuff from Memory Alpha, Scripts, and the Star Charts, and have a reasonably interesting visualization of a few series.
https://star-trek.pages.dev/
A lot of the locations are inferred due to... storytelling.
- A Markdown parser/renderer (https://github.com/andrewjk/allmark). The TS version of this was hand written and the other versions are AI translations.
- A Git client (https://github.com/andrewjk/gitologist) and a diffs parser/renderer (https://github.com/andrewjk/differator). These were vibe coded in TS, checked and then AI translated.
I’ve used these libraries to build a native Mac Markdown notes app (https://staunchapps.com/stash) and a JS script launcher (https://staunchapps.com/launch).
https://github.com/smol-machines/smolvm
- https://headsnap.io -> a platform that you can generate images of yourself based on 4 selfies.
- https://quantiq.live -> a service providing financial and historical data for stocks, as well as government trades.
- https://aivestor.tech -> an AI agent that picks small/midcap stocks and trades them using Alpaca API. It uses Reddit, news, polymarket, Google Trends and many other data sources to take investment decisions.
- @Polyglot_lingua_bot -> a voice-enabled Telegram-based bot that can help you learn new languages.
- https://select.supply -> a directory of carefully-curated and well-crafted products.
All of those allowed me to quit my day job and live a comfortable and flexible life. I still invest time in maintenance and adding new features, but I love coding, marketing and everything that comes with promoting and selling a SaaS (and I also have a serious addiction for Stripe notifications).
On top of that, I developed my own software agency where I help clients build and scale software (https://bitheap.ch).
Bravoboard: https://bravoboard.xyz
It’s a collaborative online card for birthdays, farewells, appreciation, etc. People add messages, photos, GIFs and voice notes, then the recipient gets everything together in one board.
The surprisingly interesting part has been figuring out how to make something digital still feel personal, while also making the organizer’s job of chasing 20 people for messages a little less painful :)
Presbot: https://presbot.com
It’s a small assistant for businesses and website owners. The idea is pretty simple. Visitors usually have a question they want answered, not necessarily a desire to "chat"
It answers what it can and when it can’t or when someone wants to speak with a human it collects a short predefined inquiry instead
I started building an earlier version before ChatGPT existed, and recently rebuilt it while trying to keep the original idea intact - answer the question, then get out of the way.
Both are live and very much being worked on, would appreciate any feedback.

As a climber myself, to climb effectively, one has to review their own climb, and with other people. 4D video, body positions across time, is very helpful in improving climbing. I managed to get a reasonable result (far from good) from one video, rather requiring multiple camera angles.
Haven't gotten to monetization yet, but I am enjoying every moment of making it.

I did the first Show HN a few days ago (https://news.ycombinator.com/item?id=49083987) but it was sadly left without attention.
Realized today why my filter circuits weren't working as they should: I screwed up the placement of one capacitor when I moved the design from simulation to schematic. Next post in the series coming soon.

My core hypothesis is that LLMs are trained to write consistent code (good for a billing function), but they also express design through code, resulting in consistent design as well.
Diffusion models are just now good enough to do UI, and are trained on a much wider set of visual data, resulting in more unique outputs. LLMs are now good enough to convert images to code very effectively, so the end result is better even though you have to do a conversion.
Here's a page detailing the standard flow: https://diffui.ai/blog/show-hn
And here are a couple sample sites built with it:

I am also working on a E-zine publishing platform called SVRN for interactive journals, blogs, magazines, books, and self publishing content including ARGs and interactive fiction. It is mainly so I can make my own digital comics and web stories, and episodic zines.

So far I've built a digital circuit simulator, a parser for my circuit design language, and now a parser for my simulator language (so I can run the sim on known inputs and have the machine enforce asserts for me). All to avoid the painful memories I have of verilog/vhdl.
If I don't come to my senses, the next thing is probably going to be a wave form viewer because I've wanted to use Raylib for a real project for a while now.

Written in Swift, it consists of a SwiftUI browser and a Mac/Linux server and CLI. Shares are automatically discovered via Bonjour/avahi and also published as OPDS feeds.
It can import Calibre libraries and has basic support for managing books on Kindles, but I’ve only tested it with a MTP Paperwhite as that’s all I’ve got.

We currently have two styles: lambda calculus based pieces (we depict the lambda/Tromp diagram) where we have Y-Combinator earrings (well, strictly speaking they are one beta reduction away from Y-combinator. Aesthetic oblige) and a pendant depicting a lambda expression computing Graham's number. The other style is quantum computing circuits, based on quantum computing research my brother (a physics professor) is doing: a pendant that is actually a non-local controlled-NOT gate. I wrote a tiny DSL to describe the jewelry pieces, and an interpreter to produce CAD files. We then either 3D print them or have them produced by lost-wax.
We are 200% out of our comfort zone (and love it): I know nothing of front end dev, payments, or anything like that. The diamond district in New York is a neighborhood we normally actively avoid, but if you are forced to go there it is fascinating (people examining diamonds on the corner of the street, others in fur coats in summer straight out of a mafia movie...), and especial marketing. Jewelry is a completely saturated business (luckily we are not doing this to pay the rent); we think we have a unique angle, but we are still figuring out the target audience (if there is one), how to advertise, etc.
Any ideas on marketing are welcome.

It's an externally orchestrated (meaning it's not the agent running the loop) spec driven agentic build system.
A bunch of buzz words but essentially it's a tool you use as the last step after planning your work and writing a spec, to actually have agents write the code.
But it happens within an orchestrator that is durable and which coordinates layers of agents to build -> verify -> review -> triage -> fix -> verify fixes , until the code you get as a result is as close as possible to exactly what you specified.
So you can plan however you want, use whatever harness or agent etc and then just delegate the build to the engine (MCP server or CLI)
You can mix and match models from any provider for any part of it.
I'm building this because I think micromanaging agents is what causes AI burnout and because I want to be able to plan work, walk away and come back knowing it's been correctly implemented.
https://engine.build if you want to be notified for the launch, it's going to be free to use and fully OSS (Apache 2.0)
AI is making it possible to go after bigger clients so the strategy is to focus on marketing and going upmarket. A lot of new features to add and things to learn as you move up to bigger customers with larger contracts!

When? Is a timeline game I've been working on for a bit. It's a board game I love playing with my family and I wanted a slicker mobile version I could play with them.
Contextify (https://contextify.sh)
It is very flexible, you use it the normal flow of CLI AI conversations:
Just add "use total recall" or invoke the skill directly via /total-recall or $total-recall.You can self-host your database to keep it local and sync your history across multiple computers. The local server is source available under FSL-1.1-Apache-2.0.
There are macos and linux clients, and I'm pretty close on a windows client. All share a common Swift-based core.
Inbetween that I've been working on a "software house" (don't know how else to describe it). Pretty much codex/claude running on a VPS with a web interface and the ability to actually build and publish software / webapps etc.
It came from me sitting on the train on the way home and I had an idea pop into my head for a pebble watch app, I wanted to build it and test it there and then as I still had about 45 mins left. I know you can run codex against git repos in the cloud but I didn't want to faff with that (and last I remember the allowances for this were much less generous). It's been really fun, probably many things like this out there but it works exactly how I want it to. I plan to open source it once I've tidied things up a bit more.
I dare say it’s one of the most polished PWAs in existence, especially on iOS. Nevertheless, I’m experimenting with a Capacitor build, because most customers and visitors use the app on iPhone, but few are aware of Safari’s “Add to Home Screen” feature, so they miss out on the optimal UX. Also, the app could use the exposure and user trust of the App Store, as well as flourishes (pun intended) that Apple does not extend to PWAs, like haptics and a Liquid Glass icon.

So, I built a tool to answer that. Major goals have been to keep low energy/cpu usage (so I can run it 24/7), have it adapt to the apps/traffic I'm using (rather than use static monitoring endpoints), and to deliver both at-a-glance answers in the menubar and in-depth detail in the dropdown.
It's called Breakdown. It's a free (for typical uses). It's Mac-only for now (but if enough people ask for Windows I'll port it).

Basically I'm finding myself in a bind where:
- I spend too much time doomscrolling (X, reddit, HN etc) - AI is making me lose touch with a lot of basic skills like coding, and I was already losing touch with doing real math
So I built an extension that blocks sites and forces you to actually solve a problem before you can get to a distracting site. The idea is to 1) block the reflex of visiting a site and getting a dopamine hit, and 2) at least get some mild cognitive benefit from it. I use it myself.

I've focused on building brilliant UX over the last year, and it has paid off. I've had two emails saying that they have cancelled their Jetbrains subscription for DataGrip which has been so validating.
It's been a labour of love and I'm super happy to have disrupted even a small part of the ginormous market that is database clients.

It works with standard tooling: for example, if anything in one of its tabs runs `xcrun simctl boot`, the simulator just shows up as a pane in that tab. There's a CLI for the things simctl/devicectl don't cover: taps, gestures, rotation, accessibility tree, etc.

Through the non-profit that collectively owns OBA, I've been working on a managed services offering to help transit agencies adopt the software, which has historically been beloved by users, but a real pain to set up and maintain. The software, cleverly named OBA Cloud, turns what used to require a month-long engagement with a transit consulting firm into a 15 minute, wizard-driven process.
The best part is that since all of the software is free and open source, a transit agency that decides they love OBA but wants to be locked back into an expensive contract can always ask a consulting firm to run the software for them.
Since last month[1], we've added a number of great new features to OBA Cloud, like broadcasting critical alerts to all riders in the system via push notification, and support for Live Activities on iOS.
We're hosting four new public transit systems over last month, and are continuing to make terrific strides on our other marquee projects:
The iOS app update went live, and our riders are generally loving it: https://apps.apple.com/us/app/onebusaway/id329380089

I'm planning on doing it Open Vibe Code. Add an issue and I'll set Claude on it.
PRs will be rejected out of hand. I don't want your code. I want your words.

These were stone memorials placed where someone was killed, especially in the UK. Most of them are 18th-19th century. Some are lost.
After watching a YouTube video about it and finding there was no definitive list, I registered https://murder-stones.org on Friday night and fired up claude code. There is very little on Wikipedia. I'm collating all the snippets i can find. There are a bunch of references I have collected which I'm sorting through with claude which has now run out of credits!
I have been more focused on finding new stones than fleshing out the stories so far. I have a pile of sources.
I have been researching manually for tidbits and feeding them to claude and asking what else it can find. It could find 8 to begin with but my research has got me up to around 33. There are some artifacts of that process still on the site... but it's day 2.
Its still a bit janky, but it's only day 2 really. Stack is a csv file of maybes, being sorted into sqlite, generating a static site with a python script, push to github, host on netlify. I also have a quick local flask app to enable me to hand edit the db and force a rebuild

I've been building this for a while but I'm working on getting my first 100 users now which is my first foray into the marketing/sales side of things and any tips would be helpful. Also I didn't realize until later that the name, while I think is pretty cool, might be extremely poor SEO? :-)
I also think that these kinds of post-app apps are a curious idea and will become more popular, although likely (hopefully not) through sms as the communication medium. I am off this week and plan to write some stuff about it but it feels really cool to remove the terrible CRUD UIs entirely from this part of my life. I tell my friends that even if it doesn't take off I'm never shutting it down because I enjoy using it over myfitnesspal/cronometer/macrofactor etc so much.
- Dont like the limited functions available in formulas, write your own. Yes i know this isnt new, just highlighting a starting example.
- Dont like how values are formatted in calls, write your own.
- Dont like templates, write your own script that generates the "empty" or not so empty spreadsheet.
- Dont like clicking on icons, write your own scripts or plugins that execute in context, which makes snippets to do basic things become very brief, because theres no need to load and save the file with the spreadsheet or even select the range with a query.
- Want a terminal, i have one. Everything in a spreadsheet is a file, just like *nix. Read/write a cell, is as simple as reading /cell/A1.txt or /spreadsheet/123/cell/A1, because the environment has smarts like environment values (eg SPREADSHEET_ID) that are used.
I have many other ideas which are nearly there.

Do you have a hardware list available? I didn't see it in your repo but adding it would be helpful, thanks!
It allows you to get a wake up call, like you would at a hotel, but from a real, friendly person somewhere around the world. If nobody is available to make your call, you'll get an automated call with a friendly recording.
All calls happen through the app so no phone numbers exchanged.

I love the hardware because it's the only keyboard I've been able to find that keeps a live Bluetooth connection and lets you toggle back and forth between USB and Bluetooth instantly using only a keyboard shortcut. That means you use two computers, and switch back and forth as fast as you can type. Years ago I also added a feature that changes the backlight color based on the active connection, so you can instantly tell which computer your typing will go to. I haven't been able to find any other keyboard that's quite as nice.
Lately I've spent weeks using an LLM to update the extremely old keyboard firmware to the latest firmware of its components (e.g., Circuitpython, the BLE firmware, the boot loader) and implementing all of my dream keyboard features that I never had the gumption to spend hours implementing pre-LLM. I finally resolved years-old bugs, and I added things like layer-based backlighting (so that the individual keys with relevant functions are lit), a better battery gauge, better sleep/suspend timing, backlight calibration, better debounce, and so on.
I've also upgraded the hardware and added batteries to each of the keyboards (I have three of these, one at home, one in the office, and one for travel).
It has been a very satisfying project, finally scratching a years-old itch.

I would argue that golfed code is not great for these. Asking a LLM to expand out the code and comment it results in very concise, easy to understand code - nice job on that front, it's very simple. The blurb just isn't readable as-is.

The web app allows car owners in the U.S. to see a list of all the service bulletins the manufacturer has sent out about your car over the years (called Technical Service Bulletins or TSBs). You can subscribe for new bulletins to be sent to your email as well.
These service bulletins are not only recalls but also fixes for known issues with the car.
I found reading these bulletins super helpful for my own car. There were some symptoms I would have never noticed without reading through these bulletins. For example: the tailgate did not lift up all the way in cold weather. Turns out this was fixed and covered under the extended warranty.
The infrastructure is all built on top of Cloudflare workers. I use Gemini Flash Lite to summarize and filter the bulletins.
This is my first web app (thank you AI) so any feedback is welcome!
At a high level: 1. Define your schema: TS classes model each one of your underlying tables. 2. Encapsulate your schema: Add methods on those classes (encapsulation 101 applied to your database) -- that compile down to SQL. This gives you the equivalent of computed columns and first-class relations 3. Expose your API: explicitly mark members of your classes to expose 4. Use it: Now - and this is the crazy part - the client (e.g., a web browser) can use your data-model directly to query data with SQL-level power (joins, aggregations, etc -- compiling into a single query) over RPC, securely!
Real example visuals are better at describing it: https://typegres.com/

A programming language that makes your game multiplayer automatically! It integrates rollback netcode into the programming language itself, guaranteeing that whatever you code is deterministic and can be snapshotted and rolled back. Then it integrates the networking and server automatically so you can just code your game like a singleplayer game and it'll be multiplayer automatically! I've been working on this for four years now.

https://asunder.co/montegrid - Mainly working on a Monte Carlo Excel plugin that can run on Mac. Standard scientific computing shenanigans ... one benefit of everything being Javascript is that one can use Rust -> WASM everywhere :)
Also maintaining weaving software (https://asunder.co/bower) which has so many fun puzzles in discrete math and combinatorial optimization to think about.
Cool to see everyone else's projects!
The naive approach has the LLM interacting with the DOM using raw locators and javascript. If a human curates all logical views of the DOM and exposes tools that are only relevant for each, the search space for each agent iteration is reduced by many dimensions. I have achieved deterministic results over hundreds of actions in complex business workflows. Without the human curated layer we barely make it 10-20 actions before things get weird.
Most of my thoughts are currently occupied with possibility that this works in the general case. I think an LLM exercising a tool like GitHub via properly curated browser automation might be superior to direct API access in some ways.
Current goal, which I've been working on for a bit more than a week now, is to add support for controlling the RDP (the part of the N64's GPU that actually does all the rasterization), such that programs can actually draw triangles. I'd already implemented the control registers, so the current work is defining all the RDP commands, along with documenting what they do and how to use them — which means that I need to fully understand what they do and how to use them, and that's been a fun rabbit hole to explore.
I'm currently about halfway to two-thirds of the way through defining packed structs for all the RDP commands, then the plan is to build a CommandList struct with methods to build RDP command lists and validate that they make sense (make sure all the triangle/rectangle rendering commands have all their subcommands in the right order, make sure you ain't calling them without there being a framebuffer defined as the rendering target, make sure the needed synchronization commands are in place where needed, etc.). Then that should hopefully be enough for Zig64 to draw its first triangle :)

Most tools just focus on frontend tech like Shopify or Wordpress. Bloomberry shows you who uses backend tools like Hubspot, or Workday, or Gitlab for example.
Example: https://bloomberry.com/data/github-enterprise - companies that use Github
The control plane is entirely in Elixir, using Jido & Oban to help power tools it gives an agent to get your app deployed. Uses k8s currently for the infra, but I've made the app => spec => build => deploy layers completely agnostic so we could switch out providers & methodologies in the future.
Looking for people who want to throw apps at, it's still early so no guarantees yet. You can find the website at https://infrastry.ai/ (still a brain wreck of ideas, working on it!) and I made a Discord for feedback at https://discord.gg/sBkS5ZMM3t
It's a few classes of C# right now that parses a folder and auto generates the navigation, links, titles and summary off of the folder/file structure for the 1st level and then subsequent depth is mapped to individual items in the list view not on the nav bar (although I did that too, it looked weird with higher depth). So if you have a folder with 3 files and 2 additional folder you get 5 links in the nav bar, 3 content pages and 2 list pages. No other setup is needed. No llm written code, but I used deepseek v4 flash to ask various questions and get samples of some things.
I forgot just how much depth there is to exploring a simple problem. Loving it!
My primary target right now is e-commerce due to rich data streams, however if you think your business would benefit from this tool, I would be happy to connect and discuss it.
- All our shipments in one UI (instead of searching trough our mail boxes or going to several merchant apps/sites)
- LLM processes update emails, but everything can be manually adjusted (or created from scratch)
- We have a bunch of destinations we order to (work, home, different pick-up spots), this lets me see where I have to pick up and with which pick-up code
- Real-time sync in case we update something, the other person sees it immediately
- PWA, with animations, feels as good as native on mobile
- $0 running cost (I only paid for AI sub when vibing this)

Constantly iterating through refinement and features. It's built on Rust + Tauri with a React frontend, in case anyone is curious.
I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium with an IDE-like experience.
Most recently I added a /playground area to experiment with the inspection tools via a WASM build, which I thought was a neat way for users to try the app before downloading the full version.

You create a private league, set a weekly goal (workout 3x a week), and tap Start when you begin a workout. Friends get notified and then have 30 minutes to ask for a selfie. If nobody asks, the workout counts automatically. There’s no public feed or strangers involved, just a small group keeping each other honest.
My friends and I had been doing a version of this via text message for years, but this app has been great. I am in 4 "leagues", all of them get notified at once and then I only share my selfie once and it automatically goes to any group that asks. It's motivating and hilarious to see people working out.
It's free and would love for you guys to try it and set up a league with friends or family. Please send me any feedback at amit@proofleague.com
I thought open claw was cool but could never use something so insecure.
Each run is in a container. One network bridge out so everything from tool calls to model communication goes over the bridge.
Each run has a capability token and the host checks grants for the tools attempting to be called.
Core super thin and everything from credentials handling to model communication is a package.
Finally got it alpha and have some useful jobs set up like it triggering jobs on an alert channel in slack. Debugging it with tools like GitHub kube and our work mcp and the dropping a comment on every alert with the cause.

I posted a Show HN [1] here a while back, got tons of great feedback, and have been slowly improving it since, with no real marketing. Another Show HN is probably (definitely) overdue!
Current focus is shipping a "Meet people doing X" feature - i.e. "I'm going for a cycle today in Richmond Park - who wants to join" (independent from groups) so I'm excited for that. There are some UI examples of how that will look on the landing page.

This primarily builds on top of cartography (https://docs.cartography.dev/), which I'm a contributor to, which pulls infrastructure, SaaS, etc info into a Neo4j database, makes edges, and has a standardize ontology, so you can do attack path analysis, vulnerability assessment, inventory, etc.
Seizu uses the RAG built by cartography, and adds reporting, graph exploration, automations and more on-top of it. It currently ships with a couple pre-made automations:
* Automatic dependency vulnerability fixes, like dependabot, but uses codex/claude/opencode in a sandbox to do so, which ensures it doesn't just bump a version in the file, but actually assesses whether the changes in dependencies need code updates, and gives you a thorough overview on if changes aren't needed, and why changes were needed if so. If tests break, it also watches and fixes them automatically. * A workflow to run the cartography sync, making it possible to split apart the stages, run portions of the sync on different schedules, in parallel, etc, while also making it possible to properly trigger downstream syncs, or other types of workflows. * Generic AI agent workflow, which can be staged, run in parallel, or chained together via inputs/outputs, using Seizu's own custom agent (which has good LLM provider support, sandbox support with files, etc)
Workflows are built on-top of temporal, allowing it to be quite flexible.
I started working on it because I was tired of dragging boxes/arrows around in Miro while making dependency graphs for planning projects.

A while back I did a Show HN about it, and have since rewrote and changed the concept a bit to be easier to use.
It's been tough, for some reason both Google and Bing completely erased my site from their indexes.
Another thing I'm working on: https://getpinnd.com - A small social network for map makers.
I'll use Rust for the backend even though it's probably an over kill, but it's the best way to learn for me, doing something with the language. I have some of the front end move logic and board done, I plan to start working on the API soon, after I finish a Rust book I'm reading. Here's some of the code if anybody is interested: https://github.com/thaichess-org.
I bought that printer in order to print parts for two other projects: a baby monitor (security camera) and a hat-mounted teleprompter monocle. Both using COTS part and running Yocto-based open source images. All affordable products in both of those sectors are completely untrustworthy or otherwise unsuitable for my requirements, since one of which is total replacement of the firmware with my own custom versions.
In my day job, I am a principle embedded engineer consultant working on distributed embedded systems, so all of the above software will be relatively easy.
The mechanical work will be the most challenging, as I am presently only using OpenSCAD. I would entertain suggestions for alternative open source CAD solutions, but I hope to recruit a ME (or two!) to help drive that portion of the work to completion.
It's a screen recording tool for Linux. The goal is to make it as fast and efficient as possible, while also being simple to use and install. It's just a hobby project that I am having fun working on. Here are some notable things about it:
- Written in Zig
- Uses Vulkan Video for encoding
- UI built with SDL3 and imgui
- Features recording, replay buffer, and screenshots

It's been fun working with some public city data and thinking about how to normalize information across different municipalities. Community doesn't end at city boundaries, but municipal GIS data systems sure do. I'm hoping to build tools like this for some more areas if I can track the data down.
I started the original project as an excuse to learn SwiftUI, then been using it as an excuse to test all the frontier models and etc. to see how much better we’re getting at AI-coding. Kinda fun to see a couple dozen weekly users semi-competing with each other. Obviously nothing big, but the feeling you get seeing someone else use your app is very nice.

I believe typing is probably one of the most important skills in 21st century for knowledge workers and yet one of the most neglected. Hoping to change that.
Anyone can learn to type fast, without having to think about or look down at the keyboard. We are building the best tool to help people get there quickly
Small bit of feedback that might help it stand out more from the crowd and appeal to HN users: Add in training for Colemak, Dvorak, and maybe regional variants like AZERTY.
I definitely approached it from an engineering perspective - building what I thought was missing in the space that I wanted. In hindsight, it may not be the best business to quit a FAANG job for haha.
> Colemak, Dvorak...
We have these :). Have QWERTZ and British QWERTY as well. Going to add AZERTY next and a few others.
I an also exploring more uniqie/niche ones like Kinesis keyboards, etc.but no plans for this just yet.
> good luck!
Thank you!
Some more feedback
I'm a fairly fast typist (~120 wpm) so I didn't dig too deep into your tool, but I did see that you seem to have a metric around highlighting for letters where people might be making mistakes.
You might already be doing this, but my back-of-the-envelope thought is that you really don’t want to think about typing in terms of individual letters; you want to think in terms of clusters. Ideally, you’d use some kind of frequency corpus or Markov model or something similar to break text into commonly occurring constituent clusters, e.g. the -ing in a gerund.
It's essentially the equivalent of "memory chunking" but applied to typing analysis. That’s not to say letter-level analysis is not useful (especially for hunt and peckers learning where the keys are) but as the person progresses, you’d want to introduce this idea of statistical feedback on common sequential clusters.
The reason I need a complete reimplementation is that existing graph layout libraries tend to be black boxes that you can't really fiddle with. If you want to tweak part of the algorithm, you have to fork it or write your own. With Eland, you can replace individual steps with your own implementation while keeping the rest of the algorithm unchanged. To ensure validity of the various steps, I've introduced contracts where every step specifies what properties it requires from the graph, which properties it promises to add, and which it invalidates, which I think is pretty cool.
The reason I need all of this is that I'm working on a system to display and browse through data lineage graphs. I've noticed through experience that existing graph layout libraries don't do quite what I need, so I ended up building my own.

I am still far away of 1.0, but I've been using it every day since. It's open source, you can compile it and use it as you want.
Every week I try to finish more features.
Right now, forms don't work yet (still in development), but you can use the `/search` command, and it will perform a search on DuckDuckGo.
Addendum: HN breaks a lot, specially since I didn't support nested comments and forms, but it's readeable and you can browse all links, no problem.
Give me all the feedback, I really appreciate it.
A calorie tracker for iPhone/Watch/iPad, no subscriptions, no ads, integrates with Apple Health and fully open source. Includes optional AI features, either using on-device Apple Intelligence or BYO with Anthropic, OpenAI and OpenAI compatible services (eg self-hosted).
Still tuning it, but over the last month I've used it to lose around 10lbs.
I'm planning to put it in Testflight to avoid the 7 day signing expiration and improve iCloud integration, but don't have any plans to put it in the App Store. Developed with Claude Code and Axiom skills [2].

This is an AI Harness + Platform, made in Python and Tkinter.
It has a lot of advanced features, arguments, commands, shortcuts.
Lots of widgets and the markdown parser were done from scratch.
It has a powerful API to create conversational sessions interactively.
You can learn about it on a blog post I made:
https://github.com/madprops/blog/blob/main/docs/meltdown/mel...
It's a darkroom toy/simulator for photogs running in the browser on WebGPU. It's half film sim, half creative chaos and each run is different. Still pretty early.
I've been curious about ways in which politicians who are in the minority/out of power can still make progress on issues that matter to them.
There are numerous UI form builders. And Xlsform for ODK and KoboToolbox but nothing I could find that is easy for humans and machines to grok. So I wrote a DSL in Ruby to see if it could be done. The language is mostly described at https://srp.solutions and some example usage and implementation at https://srpsurveys.com/
It was inspired by my wife having to carefully mask product photos for her online shop. Existing tools could remove backgrounds automatically, but didn’t give her enough control when the result needed correcting. So masking is a first-class feature, with SAM-assisted selection and a precise manual brush.
The backend and storage are self-hosted on hardware I own. Along the way I’ve had to solve some interesting infrastructure problems, including writing a Kubernetes operator that bin-packs GPU workloads across workers. I’m planning a technical write-up on the architecture.
It is usable stand alone but also through an R package:
https://bobjansen.net/faster-than-data-table-introducing-ibe...
It performs better than data.table in my benchmarking on a wide array of tasks and is competitive with Polars on low core counts.
Thinking ground up what AI agents would need rather than struggling later on with snapshotting live vms, or orchestration overhead etc.
rust-vmm proved really great for this.

It answers two questions that are usually handled together inside the fitting room: “How might this look on me?” and “Which size should I order?”
The virtual try-on renders the garment using a shopper’s photograph. The size recommendation component estimates the users measures, use the brand’s size chart estimated measurements and suggests a size plus a fallback.
The merchant integrates both through two widgets.
https://secchi.dev Secchi is Open Source Package Intelligence | python based
https://tuffcli.dev tuff is Capability lifecycle manager for coding agents | rust based
Both would be very helpful to be part of developer tooling. I built package intelligence when I need to monitor the downloads of my other personal project packages from package manager.
I have learned a lot over in terms of rust language, design patterns in rust, also how the ecosystem of AI capabilities within projects use cases and needs
That sounds interesting, give star to repo :D
You can build out and trade hardware in the master equipment list and immediately visualize how any changes impact mass, power, propellant, and link margins, or break power or data interface compatibility. You can also play around with orbit and operating modes to optimize things like orbit average power.
I'm hoping it can be useful in rapidly iterating early stage spacecraft designs and weighing system-level trade studies across CONOPS and hardware. Its still very much a work in progress so I'm always open to feedback.

Shipped "bring your own translations" feature this month, built together with a customer who wanted Localhero for the workflow and review layer but writes some translations themselves. Otherwise smaller improvements and marketing. Better Lingui support, for example: projects using explicit IDs keep the source text in the source locale's msgstr instead of the msgid, which our CLI got wrong before. Also wrote some blog posts, a comparison of GitHub Actions for i18n and a guide to auto-translating gettext .po files in CI (Django, Phoenix, LinguiJS). Content is slow going but it seems to be how people find us via perplixity/gemini/chatgpt.
On the side, https://infrabase.ai (AI infrastructure tools directory) grew ~16% MoM. I leaned further into the agent angle: added a public query API plus llms.txt/agents.md/etc so agents can query the directory directly, and exported the full dataset to a public GitHub repo. Starting to get som traction and people wanting collaborations.

On July 24 2026, all major eSIM providers including Akariq faced disruptions. However, Akariq was able to serve all customers even during the downtime either by switching to backup resources or issuing replacement eSIMs free of cost. Some customers of major providers like Airalo experienced serious down time. I wrote more about the incident here and what I am striving to be better in terms of automation etc [1].
One review from a customer in China [2] made all my effort worth it. They said that they were able to use Akariq to access Gmail, WhatsApp etc around the GFW. It even worked smoothly in areas like Beihai and Weizhou island apart from the cities. Tethering with their laptop was helpful too.

It was never really meant to be an SDK of sorts that other PS1 homebrew projects would pull as a submodule and depend on, but since it more or less became one I am likely going to split off the examples from the "core" (headers, CMake build scripts and tools). I have also been asked to add more examples, particularly on how to play sounds through the SPU and access the CD-ROM drive, and may cover I/O on some PS1-based arcade systems in the future.
I’ve been working up reimplementations of Nikoli puzzles to host on my personal blog, the goal is to work through the maths and then explain how it’s relevant or helps create a fun games. Nikoli is the magazine that helped create sudoku and made it famous - they have a lot of other pen and paper puzzles that are really fun to play.
I’ve also got two other open source tools I’ve built to help me work daily:
https://tajd.github.io/cofferdam/ which is a rust based cli tool I wrote to parse the ast of codebase and enforce architectural preferences - eg don’t reimplement design system for components down to DRY
https://tajd.github.io/projektor/ Is an ai native project management tool where I can plan work on the train and then have my agents pick it up autonomously. Bootstrapped it quickly but then have been incrementally adding more functionality to it. It’s like self hosted jira on cloudflare but much faster and has more agentic development tools. I added tooling around being able to autonomously work through epics, manage quality and fix identified bugs - https://tajd.github.io/projektor/agents/playbooks/epic-goal/. The goal being deliver useful features and then to ultimately surface the number of bugs identified by agents and users so that I can see the health of the project and figure out if I need to write more code myself or improve feature descriptions to reduce discovered bugs. I don’t think this is new at all but it’s reliable and done well, I hope.
This is a high efficiency, narrowly-scoped, low screen-time early literacy app for families with kids aged 2+.
It takes inspiration from Python, Rust, Go, and functional programming. It's oriented toward readability, safety, and speed.
I'm finishing up the journey of completely self-hosting. Then I'll be tidying it up for an initial release.
Each instance gets its own persistent file system, root SSH access and a web terminal. The goal is to let an agent build skills with experience rather than start from scratch on every task.
I started with Hermes as the first harness and now exploring Prime Agent. You can use it for a personal assistant, use it to build LLM wiki, connect it as part of an agent team, or run any coding agent on the cloud with dangerously skip permissions.
I’m also working towards a more general-purpose agent setup that can connect to channels such as email, WhatsApp, Telegram, Slack, Buzz.

I always get frustrated when using local file transfer tools like:
Dukto: was my personal favorite, but is tiring to run cross platform, and most importantly does not support transfer resumes (so if copy got cancelled/disconnected at 99% you either have to copy again or search for the diff and copy it manually)
LocalSend: pretty good cross platform support, but does not work when connecting 2 devices using a LAN cable, and resume support is poorish
So I'm building Tensou to be an alternative that doesn't compromise all these features. Supporting resumes, folder syncing similar to rsync, cross platform (well I don't have a Mac to test on but it should work, and mobile support is planned)
Performance wise it's on par with Dukto and even slightly better with large files (and I'm still working on optimizations for small files too)
Would like to hear HN's feedback or what other features should I add? My goal with Tensou is to be the best, most performant and feature rich local file transfer tool ever.

Already up and running: https://hailpass.com/?ref=HAILHN9 (ref code there knocks $10 off the season price) as a "season pass" for latlong/street address level-targeted hail notifications, built specifically for damaging-size hail (not just _any_ hail) on the Colorado front range. Email is free, texts are on the season pass model.
On its way, likely first ship today: https://denverbroomsday.com, same season pass model with same free email/paid-per-season text split on reminders to move your car before street sweeping days in Denver.
Recently we also got European funding and the project got some traction. Very exciting times ahead.

This work is motivated for my lifelong love for chess, my passion for Apple hardware and software (not as much as before, sadly), and my frustration of not having an Apple-native app comparable to ChessBase. My disappointment with the trend of recent macOS apps using Electron or other cross-platform frameworks instead of the native toolkits is also a factor. I miss the days when Apple users demanded more from macOS apps.
My aim with MBCA is to create a serious chess app that satisfies the needs of everyone from club players to professionals, with a native Apple look and feel and iCloud sync. Currently the app supports the iPhone, iPad, Mac, and Apple Watch. I hope to make a visionOS port later. There is still a lot of work to do, but I’m having a lot of fun developing it, and I already find the current version very useful for my chess training.

I'm in the process of polishing it up, and am aiming to launch Fall 2026. Current pricing plan is to be ~$10-15 per month for the pro tools, but provide the offline capabilities, lesson plan, and learning tools completely free without ads or weird gimmicks like a limited number of lessons or practice per day.
Over the time I've built a massive collection of assets from various stores and stuff I've built.
The solutions for managing assets seem to be largely in house tools studio build themselves and don't share.
So I'm working on a digital asset management system that plays nicely with the tools I use; unreal engine, unity, and blender.

Limiting screen time has been a primary goal in my household and has been going well. But I wanted something that would take my kids hours every month that
1. isn’t on a screen 2. educational 3. fun
In modern times, kids mostly get to know the world through images, and they deserve those images to be real or at least realistic. It really matters that the details are either correct or simplified, but not present and wrong.
For example, a compass with two norths and a garbled east is not a good start for curious conversation, but I think you should refrain from using generated images even if the details aren't so clearly wrong, as you are not an expert in most subject matters, and can't judge those errors. Instead use either photography or stylized illustrations which leave out details to imagination instead of including them and getting them wrong.
it's for people who dont own a home server, don't like to keep their laptops open and working, don't want to trust on magical stuff openclaw does and instead would like to work with the usual harness they are working with day-to-day, don't want to be vendor-locked (crush/opencode/glm-5.2 and other models/providers support to come) but want to have a way to execute ideas while being away from their laptops

and sandboxes only operate when the agents is running and sleep when not. wake up time is super quick, under 5 seconds
(on my side tho if i make it commercial, im thinking of making it free under 3 sprites/sandboxes and small subscription fee or one time payment for above)
why sprites appealed to me is that they are stateful (the disk survives sleep and wake up) and that they are fast to wake up (and it’s not a 24/7 running vm in a traditional sense)
making my own infra for that - not sure im in capacity atm
And taking a second crack at a feature flags with https://quonfig.com because I seem to be unable to put this problem down and finally feel like I have the right git native and agent first approach.
In particular: an image viewer with a small suite of extra functionality; and a browser extension for cleaning up URLs and then bookmarking them in a more organized way that I might actually use meaningfully.

Most recently I made a portable AQI meter, since the air quality here in Central Oregon can quickly get bad.
It's a small 3d printed box containing a rpi pico, an 18650 battery, an e-ink display, and a SEN66 sensor.
I hit a button, it turns on, runs the sensor for ~40 seconds to get a good reading, displays on the e-ink, and then turns off. So there's zero power draw when it's off, and the battery lasts for ~1500 readings. Accuracy seems fine, the AQI, temp, and CO2 readings all match my permanently placed sensors inside and outdoors.
Other projects include using some of the old leftover robot scrap to automate irrigation in my apple orchard.

It's been a lot of fun, Godot and agents have taken most of the pain I remembered from my childhood attempts at game dev out of the equation so I can focus on game mechanics, art and lore. I'm almost ready to start soliciting external playtesters (which I'll admit is a bit stressful), I just need to clean up the UI/card templating/art/tooltips/etc so the game is accessible out of the gate and I don't churn for reasons other than the gameplay not being tuned yet.
I've been working on this for a while now. It creates a sort of AGENTS.md or CLAUDE.md table for your database which holds all the joins, definitions, formats, and relationships, as well as what are popular criteria sets and combinations.
And it populates it into a bi-directional visual (round-trip) SQL editor. Make changes in the UI or SQL text, it goes both ways.
It's a single HTML file.
It is a research-first method for designing or reviewing SaaS products. Its central question is: What customer outcome matters, and what evidence proves that the product delivers it?
Idea or existing product → Research real customers and current work → Identify their Jobs to Be Done → Design the minimum safe workflow, define the interface and system behavior (with a sophisticated scoring system) → Validate the workflow → Implement vertical slices → Observe proof of customer progress
This is meant to be something that will help business teams be better able to communicate what they want, while producing ready to deploy tech artifacts that do not rely on AI.
More importantly, I have been working on being a Dad - something we were told would be impossible naturally.

This is a complete, bottom-to-top rewrite (front- and backend). It's a huge improvement. I used an LLM, quite a bit. It's been a big help.
We're in the last stages of the first-wave testers. This is the one that affects the app UI. After this, we expand the test, and do bug fixes only.
Also, we need to start taking screenshots and app previews for the App Store. That requires setting up a test server, with anonymized (fake) users, so we don't compromise actual user anonymity. It's a bit of a pain, but it has to be done.
Hosting an XGBoost-model for MLB totals predictions. It runs every thirty minutes: incorporating weather at the hyperlocal level and joins with player attributes that are provably affected by that weather. It also provides advanced decision-making tools with a Kelly Criterion calculator built in. Model still needs some calibration for bet-sizing but is very close to production-ready.

It has all the parts I want (lsps, syntax highlighting, a file tree) without the parts I don’t (a bundled terminal, tracking, ai)
The idea is you have a set of sources (e.g. Github, Google Docs, local file system), a bunch of transformations (templates, apps, llms/gen-ai, simulations) and sinks (communicated through changesets). The platform is like a cache layer that connects these together and allows for a graph of operations (source->executor->sink->source->executor->etc.) which allows for tracing the lineage of assets through a system.
It's an impossibly large vision made barely possible with agental coding assistance.
I also bought some cheap gloves from harbor freight and used a needle to route fiber through each finger to make a simple power glove like thing which I think I can connect to arm arm to make a cool robot game. I think of the two I am more excited for the first but its much more work than the second and my day job is getting more exciting than I would like so by the end of the month I'll have had to pick one to finish.
Personal: Local models. Agent harnesses. Track cars, turning wrenches.
Had agents build recently:
- Photo catalog app with all 100K photos in my library described by a local 9B parameter model (it is absolutely amazing and my favorite personal project in terms of genuien impact)
- Generic RAG layer (vector embedding + FTS in SQLite with RRF and document ingestiation layers for 1-2GB knowledge bases to power agent context for stuff I am interested in, neuroscience and philosophy is where I spend time on this right now, and basically every AI research paper publicly available to help agents tinker with local models). This is especially useful for local models, but it even helps frontier models because they can freely churn through without a bunch of web calls and such when you are on a topic thread or research.
- Qwen 3.6 35B A3B clean-up proxy, achieving a clean thinking + tool calling A3B that I can leave running for 24+ hours. This particular model gets stuck in long reasoning chains and needs encouragement to get on with it, especially on context tasks. It actually reasons well but then starts second guessing and loops. Built a deterministic framework to inspect its thinking and make it wrap its thinking up if it gets stuck and also to trigger calls to external models and inject solutions to problems when it gets stuck. The agent sees the solution injected from a remote model like it is its own thinking, kind of a subconscious it has no idea about. Metacognition in models, it is wild.
DSV4->GLM->Kimi is the "phone a friend" external brain pathing I built. As far as I know no one has shared all of the bugs I have 'fixed' in my project and gotten local Qwen A3B this reliable.
About to release a fun paid version. All contributors get lifetime free access.
Better running agents run longer, they need better plans. (is my bet)

It uses functional programming and event sourcing to try and effectively "solve" modern distributed web application development, so that your app code in this language can be extremely simple but not have bad architecture and gaps.
I'm probably oversimplifying the complexity, so I don't even know if it's feasible, but it's pretty fun to give Claude my crazy ideas and see what happens.

First, https://agency.nu/ a personal agent platform for people who aren’t necessarily developers, but still want to connect multiple Gmail, Calendar, and other accounts and automate workflows across them. Spent a lot of time making the interaction easy and natural, so it supports chat, realtime voice and telegram.
Second, https://vinarium.one/ something I primarily built for myself to keep track of the wines in my wine fridge, when to drink them, and what pairs well with a particular dish.
Both are very much scratching my own itch, but I’m curious if either resonates with anyone else here.

All the agent hook guards I’ve seen can be easily removed by agents (and they often do so they can get going with the task). I made mine harder to remove, and I’m working on making it impossible.
I also made “nah” easily extensible. Just point your agent to the docs which ship with the CLI, and ask it to build a custom guard.
I’m working on strong Python and Typescript pseudo-interpreters so I can detect disasters in inline code with less false positives. Bash parser is already very strong.
This is a side-project that I want to be proud off. I spend a lot of time designing, not just coding.

Recently went on an optimization bender that saw the index now become almost completely bottle-necked by CPU in the ranking calculations step. Pretty neat. Faster ranking means better results as queries run on a timeout.
Also working on making the search results more relevant by fixing jank.
Also working on some more commercial features, like the ability to monitor queries (e.g. for backlinks or brand mentions) and get an email when there are new results. Unsure if there's much demand for that, but I want the feature, so I'm buying it even if it doesn't make me yacht money.
It pulls jobs from tens of thousands of company HR pages, and only keeps them for seven days (unless it sees that the job has been filled). No reposts. Only fresh jobs.
Besides that it has a resume builder, matching system, application assistance via an extension, job tracking software, and an interview preparation helper. It turned into some fairly complex software that I ended up learning a lot from!
If any of you try it, let me know what you think.

I’m starting with the Waveshare ESP-32 watch. It has a great price tag and features, and an impossibly small battery for regattas that run for hours over two days. Designing it for super low power like this, no internet (regattas are often rural), and very high expectations (competitive sailors) is challenging and fun.
Ultimately custom hardware (probably Nordic based) will be in the cards, but for now I’m engineering a solution from what I have.
I don't necessarily suggest that anyone besides myself use it. I open-sourced it to perhaps give other people ideas, but it is tailored to just my own needs (e.g., hardwired to use deepseek-v4-flash-0731 via FireWorks.ai; supports just the tools I need).

Turns out integrating into a bigger IDE is much harder than just implementing a JavaFX view using libghostty...
It's hosted on a VPS, connected over Tailscale, and has a realtime TTS server (Piper).
The Pebble has built in transcription, so my app takes the transcript, hits the server endpoint with three possible paths:
1. Deterministic response
The server looks for certain triggers from the transcript like "Add task," "Complete task," "Set a timer," etc that will run a simple function on server and write / retrieve to a database, no LLM call needed. It then responds with the TTS output and the watch speaks. This path is nearly instant.
2. Fast response
If no trigger is found, then it hits a gpt5.6 Luna endpoint, which decides if it can answer the query itself, or if it needs to defer to the big brother model. If it can handle a query itself, it usually responds to simple questions in less than 8 seconds. It's also good about properly deferring, very close to 100% after a few weeks.
3. Deferred response
The VPS hosts a Hermes installation, and for more complicated tasks or for ongoing projects the Luna router sends it to the Hermes agent. This is typically quite slow, as you'd expect, but remarkably capable. I built the voice app to cache a few lines like "this will take some time" which will automatically trigger if the router indicates it's deferring, and then will respond with the full response from Hermes once it's finished (sometimes minutes later).
Pebble has a quiet mode, and my app will only display the text response if it's on, otherwise all responses are run through the TTS. Piper is so fast that this adds almost no time to the response.
In only a few weeks this has become the primary way I set up tasks, review and close them, set timers and reminders, log my weight, check in on the progress of projects I'm running on Hermes, and ask simple day to day AI questions.
Since Pebble is open source, AI tools are very good at building it, and it's trivially easy to set it up so that you can just ask the model to deploy it live. It's an awesome experience to tell it to change something, and two minutes later, that change is on your wrist.
Very fun project!
I pre-ordered mine last year but it looks like it's not going to come before September :(
As soon as it gets here I think this is the first project I'm going to attempt. It'll be helpful you've got any resources or source code for the Pebble STT and TTS parts. (I already have my own hermes that I want to hook it up to)
The TTS is Piper installed on the same VPS as Hermes.
Happy to answer questions or share code. I might publish the device app eventually. I hope your Pebble arrives soon, it's a great device.

When I enter a url to give me feedback for, it prompts signin, then returns you to the homepage instead of a review for the url you wanted a review for.
Conversations on the left should be named. Right now they're just "new conversation". These name themselves after the conversation is complete, but you should be able to fire off a query to a smaller LLM based on the prompt to name them asap.
The biggest thing though, the feedback it gave me was incorrect. Not the subjective parts, but the objective bits were incorrect. Here's what it told me:
> Change: Make the first viewport a contained product argument:
> 1. Navigation and one primary action
> 2. Short headline and supporting sentence
> 3. A real prompt-to-interface example
> 4. One compact proof point or “before / after” comparison
My landing page (https://diffui.ai) has nav and one primary action. It has a short headline and a supporting sentence. It has a real prompt-to-interface example. It has a before (prompt) and after (multipage web design) in the example.
I suspect that it got confused due to this being an interactive example, but a lot of this (the headline/supporting sentence) are present in the screenshot it took.
Overall though not a bad start. Good work sourcing references.

In order to make it work, I had to re-implement some math, so I avoided floating-point altogether (IEEE754 is a personal pet peeve) and went with mantissa and exponent fixed-point decimal. Or should I say binary, because the "decimal place" is the number of bits, not the number of base-10 decimal places.
Apparently this is the only deterministic, cross-platform, cryptographically-secure procedural RNG that has many types of distributions (uniform (default), normal (Box-Muller), exponential, Poisson, log-normal, beta... all with configurable inputs AND which will plot the distribution for you in the terminal!) AND is guaranteed to give you the same values... Everywhere. (Because how the fuck has this not existed yet??) Implemented in both LuaJIT and Zig with C FFI. So there you go. MIT license. Enjoy your deterministic but still very random numbers, on every OS, identically.
(It sources the best-in-class recommended source per OS if you want true random. It will do that too.)
It builds around the concept of “wolts” running a lodge. A wolt takes the identity of a rodent (racoon, beaver or otter) and can inherit any supported coding harness: claude code, codex, opencode, etc. Each wolt carries a persistent identity and memory, so they always know where you left off.
woltspace is designed to help you host your apps directly from woltspace on your machine. If it works on your machine, it works anywhere. This is done through Cloudflare tunnels that you can setup with your own domains (or using ephemeral domains).
Under the hood, woltspace is powered by tmux, which means that sessions persist and can easily be resumed and accessed from anywhere. I personally drive woltspace mainly from the telegram integration, which gives me access to my wolts and CLI literally from anywhere. This means I can chat with Claude code CLI from anywhere, spawn new sessions, all running on my own infra. It’s also all in a docker container so you don’t have to worry about approving every single command.
95% of woltspace was built from within woltspace, and it’s becoming my prefered way of building.
Another feature I really like: the “inter wolt communication layer”, IWCL, allows wolts to chat with each other, making things like having fable orchestrate a gpt 5.6 something that works out the gate.
Woltspace is meant to be used by power users (you can bring your own tmux config and use the TUI CLI) or by beginners. The default split pane makes SEEING what you’re working on really intuitive. Each wolt can host its own website where they can render arbitrary html making planning new features much more intuitive.
It’s all open source, and I’m constantly adding features to it. Woltspace is mostly self documenting, all of the features are also skills the wolts have access to. I'm also improving the documentation surrounding the project as we speak.
Looking for some feedback and users to try it out. You can one line install it with

The sounds are mainly of the FM/DX7 taste.

It sometimes sounds extremely musical and sometimes very dirty and experimental, what's normal for frequency modulation.
Please help me decide: show all and open source or continue working on it and pitch it to some big names. ;-) I have the feeling it has strong potential for prototyping, as well as taking the role of a keyboard engine. It is completely viable to manipulation via AI because of its concept.

I have fallen in love with the idea the more I spoke to potential customers. The initial feedback has given me confidence to commit to this full-time.

It upgrades your GitHub pull request review experience with a guided walkthrough of the PR optimized for reading.
P.S. Credit to adityaathalye for the change of phrasing for these posts to add "what are you curious about?"
Basically a 2d rts, fully orthogonal view, plays in space with spaceship combat.
You start with a deployable base, kinda like the old C&C, which you can place around a minable planet. Than from this you can place further structures arround that planet including the typicals, mining (2 types) of resources, researching stuff, and building ships.
The 2 things i focus the most on in this game on are
1. Responsiveness. Im a strong fan of starcraft 2 (and brood war) and have spend tons of time playing sc2. I love this super responsive controles and its the only thing i will settle for in terms of controles
2. I love the game starsector (yes no rts) for the way its ships are designed. You have a base hull that has some stats like hp / speed / etc - than this thing has basically mountpoints where you can fit weapons into. I always loved this system. So what i build is a game where you can (outside of battle) define your desired ship blueprints combined of a hull, weapons and "inbuilds" (as in upgrades). You can than just build those ships ingame.
So ye made quite progress so far , not sure tho what will be the first mode i focus on once i get a playable (as in demo) state.
Btw using godot engine as base, but some logic is running as c++ gd extensions (rts is heavy calcs , gdscript is just not fast enaugh (or im just not a gamdev ¯\_(ツ)_/¯)

I help small businesses with review management. Getting more reviews, replying to reviews, and some other related features.
Right now I'm trying to figure out how to get users and make sales. I'd love advice from someone in the community that is willing to share their experience and wisdom!
Similarly, if there are folks here from outside of the US with some ideas/feedback on getting into other markets, I'm interested to hear about that too.

I know there are lots of options in this space, but I wanted to experiment with a new approach: a compositor overlay. During transitions (like scrolling on focus, moving a window, etc.) an overlay pops up and uses _screenshots_ of windows for animating while the real windows move below. Once in place, the cover dissolves out. It's not perfect, but this makes it _feel_ much closer to native.

i'm using react on the front, pretty interesting how it manages states in the frontend and how to come up with new strategies to not trigger so manny re-renders of the UI, and on the back i use fastapi with postgresql and oauth2

In particular, I’m exploring what the infrastructure should look like when agents are the primary users: deployment, databases, domains, secrets, observability, and lifecycle management.
The goal is that everybody and their pet can deploy an app.

Both have a fair bit of traction, but is often the case, keen to do something new this month.
Google Maps is great for route planning and looking up things you already know about, but it's pretty useless for discovery. Sometimes you just want to know what places are actually worth going to as a tourist or backpacker.
It's the kind of information you'd traditionally get from guide books, but in a format that IMO makes a lot more sense - a map. Right now the scores and content are seeded by an AI, but the idea would be for these to eventually be user-derived.
It's still pretty early and I have a WIP native app which makes it a lot nicer to interact with on mobile, but it would be awesome to get people trying it out already. It's free to use, with nothing paywalled or anything like that. I'd only think about some kind of monetization if it actually gets some traction. Would love any feedback!
Desperately trying to attract new monthly sponsors and people willing to buy me the occasional pizza with my terrible HTML skills. Is it working?
If any individuals, companies (or bitcoin millionaires) would like to help a long-time OpenBSD slacker, unslack, I'd really like to focus more of my time on open source development (and advocacy), rather than making rent. Feel free to contact me.

They are all for me, with a small interest in commercializing some of them as a hustle.
Project: a local version of Claude Co-work for document organization, one of my original projects that I wanted from back in 2024, so it could help me find everything on my hard drive and turn it into a knowledge graph/mind map without sending everything over the cloud. Bonus for removing duplicates/disk cleanup.
Project: Memoria - an SMS based daily journal - my first platform! security, interoperability, yay! This started out as something for my wife to make notes on the kids milestones with an SMS reminder, but then I have ADHD type memory issues and wanted a voice based journaling system so that I could just narrate about my day and have an AI clean it up. At the end of the week it makes a little email with photos, etc for a week in review. Next step is a big lift if I want to format everything to be put into "baby books" because of the print publishing workflows.
Project: Curio - based on the platform above - helping to declutter based on capturing the sentiment of an object. My ADHD means that my memory is trigger based, and if you toss the thing, I lose the memory. I'm trying to find a way to get rid of things without losing my memory that comes from holding it in my hand.
Project: Deep Signal - an AI driven daily podcast that gathers AI papers and news based on my interests, then transforms that into a 15 minutes daily news segment. Started out on Google's platform, now just using Kotoro and Gemma 4.
Project: Book Explorer - like Sparknotes for non-fiction. Pushes everything into an ontology for non-fiction so that it can summarize it and make it very easy for me to "skim" books that I otherwise don't have time to read. Also helps me to deep dive into particular areas. This is probably one of my most frequently used tools.
Project: Meeting Notes - Before Granola existed, this was a local granola clone that used whisper. Only later did I find that the real gap in making this work seamlessly without the janky MIDI Audio Capture was that if it was a "signed" app it got access to much better resources.
Project: Hunch - a new type of trivia app that is based on bias and a "sense" of what is true. Made so we could play trivia across multiple education levels and generations with everyone still having fun. Still in development.
Project: Drucker MCP - using an MCP to inject prompts from a custom "library" so that I could steer a big model towards as multiple opinionated experts. Meant for business / entrepreneurs - I want to think like Peter Drucker, Alex Osteralder, Rogers, Scott Anthony. This one is the one that I hope can "make a dent in the universe" because I could make it freely available as an MCP and it can help micro-entrepreneurs in the Global South.
Project: personal finance app. keeping it local.
I suppose to get the triple crown, I need to make a work out app so I have "journaling", "fitness", and "personal finance." Or could be a to-do app. lol
Heck, most of these are still in development - but the Audio Capture was abandoned for freeware.
Yes, to build a radar graph. But why not be a beginner, working professional, and a parent? How do I pick only one thing that I do after 9 pm?
Your onboarding is complicated when your app's premise is just do simple things, but halfway through onboarding, I've lost confidence in the path you are charting.

Feedback is more than welcome.
Since I could not find anything out there, I am scratching my own itch.
Do introductions of key concepts and explain what real scalability ladders look like and how to guide an AI to build it.
I'd be interested to be a beta user when you get ready to share.

I’ve been waiting for a spine surgery and to do something with my time I started experimenting with an idea I had. It completely pulled me in, and helps me to distract myself.
It is work in progress, lacks of documentation, I am not even sure I will release it.
https://github.com/mixpeek/amux
The basic idea is that instead of trying to solve the general case in robotics (ie, the humanoid companies - multiple tasks, multiple environments, generalization, etc) which needs billions of capital, can you efficiently deploy current tech to robustly do one task in one environment for cheap.
A new kind of GPU library written in rust with backends for CUDA, DX12, Vulkan, and Metal (tenstorrent and wgpu are planned) and bindings for rust-dynamic, python, c++, c, and dotnet (Java and Fortran are planned).
Uses the slang shader language exclusively. All submissions are expressed as graphs (like cuda graphs), are retained automatically (sometimes partially with a graph partition algorithm), and automatic synchronization of GPU resources. No runtime dependencies (slang is vendored) and new calling convention for shaders using a virtual entry point that allows resources to appear as arguments to the shader 'main'. Includes automatic VRAM and resource recycling for device resources.
Shader coroutines, rust shader authoring, and automatic kernel fusion are planned.
Supports both GPGPU and graphics.
Made it because cross backend GPU libraries usually either target lowest common denominator or are specialized for either compute or graphics or ML. In my experience GPU programs and frameworks are written to target a different kind of machine than a tape machine, but nobody outside of tenstorrent have bothered to describe that machine. So I defined a new kind of abstract machine for cooperative resource-oriented computation called a Fondaco machine for which goldy is the reference implementation.

I'd hoped for a more meaningful update from when I first mentioned Vestiges last month (https://news.ycombinator.com/item?id=48884984). But I've often felt discouraged and haven't worked as much as I'd intended.
As was recommended by guiambros last month, I started the process of setting up Vestiges on Steam, but that's still in progress (currently, my identity is being verified). I also set-up at micro.blog (https://ksaun.micro.blog/) and (https://mastodon.social/@ksaun), but haven't posted anything yet.
I bought a Linux laptop for this project (I was working on a 2020 Surface Book 3). (I had used Unix in the 1990s, but not much since then. The video game industry being so Windows-centric, I'd stuck with that OS throughout my career.) So recently I spent a few days enjoying (not sarcastically!) setting up my new computer and work environment. In doing so, I also took improved some aspects of my development process.
Limited meaningful work on the game itself. From a technical perspective, I could release the demo now, but I'm dissatisfied with the content (specifically the writing). Not that it needs to be amazing just yet, but I want it at least less embarrassing. As I've worked with some of the best game writers in the industry (in my opinion; people like Chris Avellone, George Ziets, Neal Hallford, Brian Mitsoda), I'm accustomed to quality that exceeds my personal ability. And this writing work requires greater focus than I can usually muster, so I've been procrastinating, polishing other things that were already sufficient to ship.
Since last time, I've finished most work on tutorial features and content as well as the other implementations I wanted for the demo. For the modes that are ready, I added full support for keyboard-only play (which was a more substantial effort than I'd anticipated, taking close to two days (very part-time for me, but Claude was fairly busy)). I also now have an MCP server implemented so that Claude can playtest as a player would, but I've only just started to make use of it. (And some progress on the aforementioned writing, just not much.)

Still on plex, next step is Jellyfin.
A cheap rowing counter. Competitive rowers use a training device that counts their strokes per minute. I figured out that the major parts are really cheap, even as individual purchases, so I wanted to build a budget version. So far it counts strokes fairly accurately and I've just completed initial tests of the display.
Drone experiment. I'm building a image recognition drone from scratch. It's based on a H743 Slim V4, with an RPI5 and a OAK-D Lite. I'm currently trying to figure out why the back left rotor is producing way too little thrust.
Like everyone else, I'm also working on an agent harness. tl;dr I don't trust any agent to not be dumb, but the agents seem to have some success recognizing when the work of an other agent is dumb. In early tests, the back and forth seems to provide more stable and better results.
Basically a drone that relies more on the camera and less on the accellerometer and the GPS. Although it still uses both a lot.
Indexing multiple captured video streams with awarded action points and adding athlete/referee positions overlay. Stretch goal -- controlling PTZ camera for predictive capture of the high intensity actions.
Nothing too interesting though.
I have more interesting projects, but these have to come after I focus on more pressing reallife requirements; on my next todo list, though, I want to extend the code I use to compile from source. I track almost 4000 programs already and can compile most of these (for some reason GCC 16.2.0 does not want to compile today); I want to extend this, finishing an automatic build of the linux kernel and full bootstrap into a new system while also adding more language bindings, such as lua. And also allow for this to be compilable via a web-interface.)
https://wafertown.com // the first LLMORPG, you write a prompt and your character "lives" through a simulation of life using it as a guide, interacts with others, etc. sends you a summary of what it did and allows you to steer it for next day. think of it as a small tamagotchi but with hundreds (hopefully thousands!) of other players
This is very cool! What's the stack for the actual server?
Right now it is Node.js and I store data in an in-memory database.
(I keep no history, state is volatile, I think that of being a feature :)).
There's some work on the roadmap to "standardize" the API spec. and publish servers for most common stacks: Docker (agnostic), Go, node.js and Python.
Too many times I have been burned by applying to scam listings or people who are just to self-promote and use people who want a job as a marketing channel (looking at you BetterStack, fu in particular).
I want people to be able to discuss and flag companies which are lying or just a waste of time, yet HN refuses to do anything about it and doesn’t allow threads as discussions and removes comments.
Hit me up if you want on the beta testers lists, already got a couple of people.

..but I get to take the common stuff from each and put it into an open-source Godot framework so as to not feel totally useless :')
https://github.com/InvadingOctopus/comedot
and all of this is making me want for a better programming language designed from the ground up for games, with no need to care about hardware, so I've been brainstorming and rubber-duckying about that as well.
