  Working on https://nadir.dev, a small app for running daily technical knowledge tests. It started just as a way to see if depending on claude-code so much recently dulled my expertise in Ruby/Rails but it turned into something bigger after some friends asked me to add non-technical topics, so now it's both for developers and "normal" people.

  Still OnlineOrNot (https://onlineornot.com/), 5.5 years on.Most recently I shipped an MCP server (w/ OAuth sign-in) recently to expose the API a bit better to agents, a TypeScript SDK and rewrote the CLI to use it. Also been reworking the terraform provider to cover the whole OpenAPI spec's surface area.Just before LLMs became a thing I took the time to rewrite from having a private GraphQL server + public REST API to just using the REST API to build the product, super glad I did.

  I've been working on a voxel game engine called Bonsai for ~10 years.Probably the most interesting thing about it at the moment is the editor. The world, and most things in it, are represented as collections of SDFs. More accurately, they're density fields, but, potato-tomato.Bonsai has undergone a large rewrite over the last couple years that's nearing completion. A world edit is defined as a bunch of SDF parameters which get projected/rasterized into the voxel grid by a shader on the GPU. One neat thing about SDFs is they've been thoroughly researched and documented by a guy named Inigo Quilez, and they have a lot of nice mathematical properties. For example, you can do a smooth union of arbitrary SDFs to get nice rounded contours where shapes join.I've written every system from scratch, all the way from the memory allocators and font rasterizer to the collision detector and simulation loop. I even wrote a metaprogramming language as a replacement for C++ templates, which is a whole other story. IIRC the only external dependency is the C runtime library for starting the process and my very occasional use of variadic functions arguments.For a long time, an explicit non-goal of the project was to ship a game. It sounded insane to me to write an entire 3D engine and then ship a game. As it turns out, I've gotten it to the point where I can actually make a game. I've got a start on the game systems in a closed-source repo, and hope to have a steam page for it by the end of the year.I'll do some shameless self-promotion and leave some links here for anyone interested in looking at the engine, language code, or some pretty pictures.https://github.com/scallyw4g/bonsaihttps://github.com/scallyw4g/poof

  I'm working on StoryStarling (https://www.storystarling.com). It creates custom hardcover children's books from scratch around any idea, instead of swapping names into pre-set templates.We mostly focus on things you cannot find in bookstores: bilingual stories with parallel text for multilingual homes, and non-fiction for kids who have hyper-specific obsessions (like tunnel boring machines or wastewater systems).

  https://audioguidekit.orgIt is a React-based OSS audio player I developed primarily for museums and tour guides as I am really close to this industry and i was trying to scratch my own itch. In practice, thanks to the flexible design and architecture, it can be used for any use-case where you need to deliver sequential audio. Would like to hear any feedback or connect with someone who would need a solution like this.

  https://curvefit.appit's a weight-training app that helps you train along your "pareto frontier" of weight vs reps. The idea is to train at lower weight-higher rep, medium weight medium reps, and higher weight, lower reps for every movement. I tried to develop my own weight training program following bits and pieces of advice from bodybuilding forums and ended up injuring several tendons in my first year. So I did a bunch of research on tendon strengthening as well as what's most effective for hypertrophy (reps near failure) strength (reps near maximal load) and injury-prevention/frequency (not bringing yourself to failure too often) and designed an app to automatically prescribe and advance weights and reps based on your learned strength curve (Brzycki-like, with an added shape parameter)The app is designed to make use of the free Cloudflare tier, so I can support thousands of athletes for just the cost of the domain name. I'm primarily interested in understanding the "Fatigue curve" - right now I have some basic per-set fatigue modeling (basically a log-linear strength dropoff) but I think it could be much better characterized with more data. I could go on and on about the modeling but my intention is to keep it free (maybe add some non-intrusive ads on content pages if it ever starts costing me a few pennies a month) but my primary interest is to be able to do statistical analysis on the data.

  https://www.abejora.com - timesheet software for freelancers and small teamsWe created it as an alternative to the price gouging that happened over the last year at various timesheet SaaS companies. The idea is that good software should not cost 10x as much just because 10x as many people use it. In our opinion, software should also be functionally complete. There should be no arbitrary tiers that only exist to force people into more expensive plans.The stack is Elixir with Phoenix LiveView, deployed on a Talos Kubernetes cluster. This is different from what we normally build on, and honestly quite fun.Lately we have been thinking hard about the temporal nature of timesheet software. Many things get quite complicated once you factor in historical versions: the need to retire, lock, change, reopen records or rates, and so on. We have been working hard to polish Abejora to make everything accessible, user friendly, and intuitive.

  https://common.charityI’m building the UK’s ‘big data’ charity with some awesome co-trustees and volunteers. We undertake big data projects in service of human flourishing, collect and synthesize datasets from hostile actors or freedom of information requests, and collaborate with other charities to build useful things that facilitate effective coordination.The context is that I co-run the UK’s largest and most active landlord review platform ‘Marks out of Tenancy’, and the data we aggregated and ended up being able to host and query did a number of incredibly high impact things:- our system for identifying how many people lived in a property started getting used to find victims of human trafficking - our system for checking for HMO licensing got picked up by councils to detect 100% of illegal or rogue landlords in the scan area, as well as detecting illegal short lets. - our longitudinal data collection on housing conflict between tenants and landlords directly led to increasing the rent repayment order threshold in the renters rights act from 12 months to 24 months.So after seeing how much data is out there ready to be used for advocacy - but just left untapped by a profit driven sector, and after years of experience as ‘activist data practitioners’ or whatever you’d want to call it, we decided to launch something that could be a home for those projects in the spaces we’re in over here in the UK.We’ve already got some awesome projects underway and we’re excited to see how year 0 goes for us!

  I run a small experiment on this: 29 paper-trading accounts on real US stock prices, $100k each, since July 27. Four AI models (ChatGPT, Claude, Grok, Gemini) each write a trading rulebook and rewrite it every day from their own results. One account is a fixed rulebook that no AI ever touches, as a control.Result so far (paper, 34 trading days): the no-AI control is +13.0%, the S&P 500 is +3.4%, and 25 of the 28 AI accounts are below the control. The best single account is a Grok-written "patience" book at +40%, which I treat as one lucky account in a choppy market, not a finding. At the trade level the AIs and the control look the same: 3,212 closed positions, median +0.06%, median hold about 2 hours. They trade a lot and mostly go nowhere.Everything is public, including the losses and the retired strategies: https://aitradingcompetition.com/which-ai-is-winning.html and the full trade file as CSV at https://github.com/ckamelhar-collab/ai-trading-arena-data. Paper money only, not advice, nothing for sale on those pages.

In the output, you get the official USCIS pdf form filled.

  I'm still working on https://openaltfinder.com; a place to help you discover open source alternatives. Got quite a lot of traction this month due to Google/Apple Maps renaming Lake Ontario.But overall it's a struggle, the site is still in Google jail/sandbox, so it's not even seeing any Google impressions. So most traffic is due to being very active and posting wherever I can.

  I have ALOT of free time since quitting my job.0) money-money-money: A sub 15Kb server-less opinionated household budgeting tool [0]. Why? Its made to be extremely compressible, so you can edit your household budget and share back and forth with your partner via short-links or QR codes. The idea is you edit your budget, send the link to other party, they can view or edit and send back to you without a server in the loop. [0]1) slices: An alternative AI-first ADHD-friendly architecture experiment where everything you code is a "slice" with a shared event pool. A slice is a fully self contained "feature". Slices can only communicate with other slices through a shared event pool. Inspired by small-talk, vertical-slice architecture, and ADHD. I used slices to build a self-modifying IDE too. [1] [2]2) text compression experiments: I'm experimenting with approaches to compress text in pursuit of the Hutter prize. The idea is to take the entirety of the English Wikipedia, and compress the text as small as possible whilst still being able to reproduce it. [3]3) tiniest maze solving neural network: A write-up work in progress on a maze solver I built with heavy LLM help, managed to get a 14 byte neural network solving 96% of unseen mazes.

  [HUMAN-CODE]I'm building a video game. It's part Valheim, part Ultima IV:https://stravaeger.com/You can play the demo in the browser now (mobile as well as desktop), but I'll be packaging it up for Steam soon.It's all vanilla javascript, html and css. No AI, no 3rd party game engine, no build system even, and just a couple external dependencies for things like networking that I didn't want to reinvent myself.It's been fun. I'd love to get some feedback!

  Working on https://localhero.ai, on-brand automated translations for product teams. It mainly runs as a GitHub Action, translates new strings on your PRs against your glossary and style guide. This month focus went mainly on MCP and stuff around that. Thinking a PM/designer/etc who wants to bulk tweak copy without touching git or similar. Claude Desktop/ChatGPT turns out to be a pretty nice surface for this, the assistant finds every key that needs changing and organises the work, Localhero keeps it on-brand. A pretty sweet workflow. Also doubled down on Lingui and Django support. Also been fighting some spam. A 400 from our mail service showed up in error tracking, looked like a malformed address, turned out something else. Someone setup a bunch of bots to signup and try so send crypto spam using the team invite function. Kind of persistent, I fix a few things and it tries a few others. Finally stopped, interesting to see it live like this.On the side, https://infrabase.ai (hand-verified AI infrastructure directory) launched a Media Generation category, image and video APIs after a run of requests for it. Also the submission spam is way up here latley, been improving the detection here as well. Also seeing real interest in paid listings now, including one that started as a link-buying request I turned down :)Been doing a lot of AI assisted emailing, so I have started to work on a little review UI for AI generated text, comments on specific words, inline edits, Claude picks up both and revises in place. Like a PR review interface for text. Turns out pretty good workflow with Claude watching the files for new comments, editing and commenting back right away.

  https://multicoder.dev/One UI for every coding agent - VS Code extension (GUI) to launch and work with any ACP-compatible agent harness. Supports Claude Code, Codex, OpenCode, Qwen and many others - https://agentclientprotocol.com/get-started/registry . Does not require any new subscription or user ID - this is still handled by the harness, so you can use existing Claude Code or Codex subscription. Multicoder just gives you a high-quality GUI to work with any of them without mental switching cost.

  A coding harness that works more like pair programming and less like code review:https://www.opairdev.org/It has 2 modes, driver and navigator, that work like the driver/navigator roles for a human/human pair. In driver mode, Opair is similar to other harnesses but with less autonomy for the agent. In navigator mode, Opair has no access to writable tools at all. Instead it monitors the project directory for changes as you make them in your regular editor, and comments on them in real time.Why? Because big changes are harder to understand if you're not directly involved in working on them, and I want to understand the codebases I work with. I use it as my daily driver and it's perfect (for me). I recommend everyone should consider writing their own harness. When you spend so long working with something, it's nice to have it perfectly tailored to your needs.

  I’m very interested in building tools for coding agents (where I spend a lot of my time).I’ve been building https://smalldocs.org, it’s a simply styled, but functionally deep, artifact layer for agents. It’s open source and free to use.Because it can incorporate charts, diagrams, spreadsheets, etc. in one artifact, it’s good for creating (and optionally sharing) agent created analysis.It has a local library for all your Markdown files, and a cloud library (my one paid feature) too. Both support tagging and rich search/filtering. I find it turns SmallDoc artifacts into little checkpoints in work I can easily circle back to.Thanks for reading!

  I’m working on translating the Renaissance — it was mostly written in Latin and 90% of it has never been translated to English. Even big names, like Ficino, Durer, Kircher, Fludd and Drebbel. And that’s Latin— things much more sparse in other classical languages.https://SourceLibrary.org is a hub that now provides over 20,000 translations of classical texts in dozens of languages (Latin and Greek but also Chinese, Sanskrit, etc). We always provide the original image of the text next to the AI translation (so if you don’t trust it, you can do it again). For a sense of scale, SourceLibrary now hosts more words than English Wikipedia!You can freely connect to the public MCP for research; that way AI can read books and not hallucinate quotes. In Claude, it also retrieves images directly into the chat.This is a philanthropic project based at the non-profit “The Embassy of the Free Mind” in Amsterdam, a rare book library devoted to free thought and mysticism. https://embassyofthefreemind.comSourceLibrary is totally free and open source. If we can raise the money, we hope to translate 100k books before the end of the year.If you want to dive in, I’d suggest trying our research agent with a rabbithole topic of your choice: https://sourcelibrary.org/librarian/

  I've built Flexito, a website/mobile app (it's PWA) for daily stretching and mobility exercises.As many of us here, I sit too much in my chair during the day and I'm trying to stretch more often and strengthen my back/core muscles.There are a lot of "free" apps out there e.g. Bend that are helpful but I was annoyed with ads and limitations so I built one for myself. Now I use it daily.The app is simple, you have about 100 routines to pick from and you can even build your own from existing exercises. Each routine comes with simple images, a link to a Youtube video and a timer. There are a lot of 5 minute routines that are perfect for a short break during work.There are no accounts and I don't plan on adding any more features unless highly requested by users. I've built this for myself but I'm sharing it here as others might find it useful. Any feedback is appreciated!https://flexito.fit/

  My quirky wishlist app https://thingstohave.app is finally done and heading to public launch this or next week.I already partially covered the last few months of app development in this topic. But actually, its development took way longer, as only this iteration started in 2024. So it is the end of a long milestone— this launch date initially was to be a year ago, but I procrastinated and missed important for such apps holiday seasonThis year I was able to go way beyond last year’s backlog, and now I’m releasing a fully finished app instead of early access.I’m proud of the result — a lot of overengineered stuff that is not viable in any commercial product, especially in what appears to be a simple CRUD app. For example: image loading from blur, unadvertised but very advanced DnD everywhere, natural language currency inputs with sorting, platform-agnostic quick add, and many more.Its stack is also very fun: it has been running on the Cloudflare Workers ecosystem since 2023, and is powered by a custom Inertia.js adapter for Hono (that predates the official adapter by one month, lol), with Vue SSR. That all enables me to write old-school MVC with Vue as a template engine for views. It also proved to be very easy to work with and cheap to run.With a tsunami of vibcoded beige wishlists, my weird app stands apart, for sure, but I’m unsure about its appeal to the average customer.

  https://fabulae.orbilii.com - A Latin language audiobook containing both volumes of A.D. Godley's "The Fables of Orbilius" which are entertaining intermediate Latin stories written at the turn of the 20th century for use in British schools.The audio itself is in delivered with the restored classical Latin pronunciation and contains spoken nuances like vowel nasalization, elision, and prodelision. I used a wav2vec2 model to generate forced-alignment data, so you can easily follow along with the text as it's being read aloud. Each word in the text is richly enhanced with pedagogical details like: lemma, citation forms / principal parts, morphological segmentation and analysis, inflectional class with complete declension/conjugation tables, verb category, contextual lexical information (i.e. specific L&S sense), Classical Latin IPA pronunciation, UD style syntactic function and relations, predicate valency, and concise English definitions. Spoken instances of elision and prodelision can also optionally be displayed.From a nerd perspective, one of the things that makes the system interesting is that the documents themselves are entirely in XML, and I use the soon-to-be-removed-everywhere in-browser XSLT feature to render the HTML, so you can see the underlying XML structure if you view source. Each sentence in the text contains provenance records so you can see the language model and parameters that performed each language enrichment task. The site UI is largely bilingual, and you can view it in either Latin or English.

  https://github.com/ninjaxtools/slopdexThis is my attempt to improve my agentic coding workflow by giving the agent an index into the source code through vector embeddings and LLM generated descriptions with local sqlite as the storage backend.There are many similar tools, but I wanted to learn how such a tool can work by building it myself. What I like about my own version is that I kept things simple - no MCP, no server, no watches, just a CLI that uses git commit hashes to reindex only what has changed.

  Two things seriously, one in (partial) jest:A copy utility that can efficiently deduplicate as it copies, even when the filesystem structure is different. Whilst there are many utilities that can deduplicate, they often either rely on files being on the same filesystem, or having the same structure. If a duplicate is detected, it can either be omitted or hard/soft links created to files in one or more reference locations. In practice I have found this to be invaluable for merging and efficiently consolidating multiple hard drives with partial backups of photos and music, maintaining the complete trees of all sources on a single destination, or only copying files that are new.Secondly, an efficient protocol for text applications over a network. Think a combination of TN3270, SSH and JavaScript, with a very lightweight client/server architecture. Whilst SSH is great, latency kills many practical applications - this attempts to solve that. It also intends to make applications very simple to implement. As a proof of concept, I implemented a simple forum with login, optimistic posting, quoting, a text editor with mouse support in about 600 lines of code. The protocol, client and server themselves are agnostic to any particular UI toolkit.Thirdly - microfish, poor person's microfiche using laser printers and autoencoders to preserve readability and machine recoverability of high density prints. Since consumer digital archival media seems to be dying...

  I'm working on making bcachefs useful when you mix both SSD and HDD in one filesystem.At the moment, even if you set up SSD for foreground operations and HDD only for background, more often then not, your write latencies are those of the HDD. We can do better.See https://paquari.com/posts/bcachefs-ssd-hdd-progress/ for a progress report. (Disclosure: the write-up is an AI summary of my notes, so don't expect any brilliant prose.)I'm also working on resurrecting stabilizer (https://github.com/matthiasgoergens/stabilizer). Stabilizer is a way to make program performance less dependent on the linker and layout lottery. But it has sadly fallen victim to bitrot.I'm doing some minor contributions to other parts of Linux like ZFS and ext4, mostly as a byproduct of experiments I'm running for my bcachefs work. Another somewhat ambitions project is to make swapfiles on ZFS and bcachefs work (or work better), at the moment the problem is that writing swap on them might need to allocate memory exactly when you are out of memory.

  This is very niche, only for people who do astrophotography or astronomers, mostly because of the required specialized file format.I have slowly built out a set of tools for asteroid orbits and photometry (measuring how bright stars/asteroids are).It is very rough still (Desktop only), and it only supports the FITs file standard.https://www.astrometry.space/Basically it is a full professional grade telescope processing pipeline in your browser. It does 2 queries to some custom databases to identify known asteroids and stars, but all image processing and calculations are done in the browser. This means the backend is pretty tiny. That said it is running on an old box in my closet, so queries may take a while if it gets hammered.I built it since I have worked with quite a few astronomers over the past 4 years and I keep watching them do the same steps, purely built to make my friends lives easier. I wrote it all in rust and managed to compile it into wasm. With some help from fable as I am not a frontend guy at all, I built it into a small website.Some of the code is public, the orbital mechanics code I wrote while I worked at Caltech. Which is being used on SphereX, NEO Surveyor, and the Roman telescopes to identify known asteroids. https://github.com/dahlend/kete

  Https://www.pulado.com/Built this 18 years ago. Flash arcade game engine. 10,000+ games built by users on it. 2+ million plays. Lets you build mashups of classic arcade rules like Breakout+Space Invaders as one example.It's been unplayable since Adobe killed off Flash. It uses a lot of dynamically loaded remote assests so Ruffle hasn't been able to run it.Recently had Claude Code fix the Flash client so it would work in Ruffle and then had it convert the code to haxe (let's call the haxe version v2). It was an interesting conversion because Claude made a lot of wrong assumptions about how the engine worked so had to have it test every feature and match parity between the ActionScript version and the haxe version numberous times and play test it all. It's pretty close to parity now but still ironing out kinks in the engine. The existing engine art is very 2010esq.On the game editor side converted it (it just re-wrote it) from ASP into JS. Now with an AI agent to help configure the settings and generate fresh artwork in additional to the manual editor.The art has some very specific rules about orientation etc which the pixel art generation models seem to struggle with a bit but getting that aligned as well.It lives again!

  I'm building notmutt (notmuch + mutt). A tabbed, async terminal mail client with unified inbox, with included html viewer(with image support), mcp server, lua scripting. I tried using neomutt with unified inbox and I ended up messing up my maildirs every so often. i also tried adding async tasks(for sending) to neomutt, but there was no interest from the project, which made me realize that there is a lot more to it than just sending async mails.The goal is to have a very fast terminal mail client where you don't have to wait for any operations and that is tightly integrated with notmuch(a common mail full text search engine) tagging engine, and other workflows(like crm queues and ai summary's if enabled in the config).There is a document that explains why it was made in go. It has the best notmutt cgo bindings, and there are other reference terminal clients I can use as reference. althogh himalaya(rust) also looks interesting.I would love to get some help with it, but I don't know where I should post it to get people interested.https://github.com/fishman/notmutthttps://fishman.github.io/notmutt/

  I've spent the past few months working on little projects mostly coded via LLMs. Used it to build my own little AI agent in python attempting to keep it stdlib-only, and a little blog engine with MFA. Things I would never have previously been able to do as a sysadmin/infrastructure but not developer. The struggle I'm finding with it is how to go from good enough for me to good enough for production. After being stuck in QA/review hell trying to use LLMs to assess the code, I've started trying to unpick it myself. I can't help but feel that the time spent learning the vibe-coding approach wouldn't have been better spent just learning software development properly.While that's been frustrating, most my fun has been on the non-tech side.

  I've been working on anti age verification/surveillance projects lately. I put together this thing I call The Mandating Honeypots Project and it shows how anyone with an internet connection and copy + paste skills can trick Linux D-Buses with a simple Python script, proving that if companies want to verify your age by asking the D-Bus interface, it's easy to just tell it to always send 18+, making the whole thing useless. The only reason you'd want ID verification is so you can create the world's biggest and sweetest honeypot.(https://github.com/Tori-Tech/Mandating-Honeypots-Project)In that project, I also proposed a tool with heavily redundant password protection that parents could use to keep kids from tampering with the service so the government can stop saying that this is for the kids. I'm planning on doing a mobile device version and/or an ID database focused version, but that's still in the planning phase.I also want to do a Windows version when they release their 'GetUserAgeRangeAsync' API, but idk if I'll be able to. Windows is always a pain to work with.It'd be nice if someone had advice or ideas to share, too.

  Posted this before, but Odds Assist Pro (http://pro.oddsassist.com/) and Sportsbook API (https://sportsbookapi.com/)The Odds Assist tool started out as a way for me to quickly QA the data from the API. It then turned into its own product as an odds scanner and sports book advantage finder (mainly arbitrage, +EV, middles, etc). Over the past few months it's really pivoted toward prediction markets and collecting and displaying data to get an edge on markets that are soft.The pivot to focus on PMs has been pretty fun from a development perspective since there's so many niche markets to look explore. I've always liked math, I'm a bit of a digital hoarder, and I've got ADHD so finding random things to collect a bunch of data for just to test a hypothesis just hits my brain in all the right ways. It's also given me an excuse to learn more about ML what has been great.

  I'm working on TableForge[0], it's a browser based, solo or multiplayer, D&D 5e game. In TableForge, the DM is agentic with access to tools strictly following 5e rules. The DM is responsible for narration and reacting to players but your character sheet, inventory, spells are all real server resources you manage. The DM can interact with them through deterministic 5e-based tools (dice rolls, damage, sheet updates, memory). Players can play in real time or async. You can provide the DM a premise (or pick one from the library) and it'll flesh out a full campaign story arc. Either way it's a fresh story arc reacting to your actual decisions, every time.It’s been really fun working on it and especially rewarding seeing the game bring friends together.[0] https://tableforge.gg/

  I’m building a website for discovering first names that’s enjoyable to explore: https://abracadanames.comIt started with a family member telling me they were frustrated with existing websites. What I noticed is that in many cases they feel cluttered and not smooth to use, almost like a 1-to-1 translation of the underlying database queries, where they have you choose filters and sorting options upfront then browse the paginated results.I wanted to avoid all of that by creating a different experience; I built an interactive full-screen wall UI with infinite browsing so that most of the screen space is dedicated to the core content. I worked on the name sampling algorithm to try to make it as enjoyable to browse as I could, and the only filter displayed by default is the one to select genders.More advanced queries are available through the search field which supports natural language queries, running on a local multilingual interpretation engine with a cloud LLM fallback. The database engine is custom built with Rust, compiled to WASM for higher performance when running on CloudFlare Workers. I don’t use an external DB service for names today.What I’m pretty proud of is to know a lot of technical work is hidden behind that UI, and how it has been shaped by the experience I wanted instead of the other way around.

  Haven’t started, still in the planning phase, but I want to build a Tamagotchi for readers. I’m calling it Tome & Tail: a little black dragon living in a pixel-art library on an ESP32-S3 with a small round AMOLED screen.You’d start a reading session and the dragon would read alongside you. What you read would influence its appearance and habits; lots of sci-fi might give it starry wings, for example. It won’t die if you go a week without reading.The plan is to keep it playable offline, with optional syncing to Booklary, the reading tracker I’m building. I’m leaning toward C++, which I never used, so it’ll be a learning experience.Currently waiting for the Waveshare board to arrive so I can start development, and looking for an artist to commission the pixel art. Used GPT to design a concept[1], which I’ll use as examples to the artist.This will be my first ESP32 project, so getting the dragon blinking on screen is the first milestone.[1]: https://i.cpimg.sh/57EC5380-0FF7-4646-A943-971350FF98D2.png

  I am working on vorfract, a Voronoi voxel world which uses Voronoi cells as voxels instead of the regular cubic ones.It's an early version so many (if not most) things that would be in a game are still missing at the moment (though planned on paper).One interesting thing is that because the Voronoi voxels are so malleable, things like round or hollow worlds are a pretty natural outcome.In parallel to working on it, I've been mostly using it to build and improve my own voxel castle with a pointy roof, slanted walls, custom built stairs, tables, chairs and all those nice things.In the last update I added a CRT filter and some pixelation options as I find that appealing. As for the future (maybe as the next thing?), I guess I'd probably like to add the ability to build less blocky things like round towers (or flower vases!), but that is still very much a work in progress.The Web version (WebGL) is completely free (and will stay that way):https://jazzprogramming.itch.io/vorfract

  I've always wanted to make a video game, and over the past few months have been building one, Fairway Rogue. It's a procedurally generated, deck-building, mini-golf roguelite.

I've spent quite a bit of time working on tools to help me balance the various game mechanics.One weird learning, it was much easier to get it on the iOS app store, than the Google Play store.

  I built a simple, stoic and free markdown note app (free) called Beauty. https://www.markdown.beauty/Why? There's no why. The world doesn't need another Markdown editor. I still made one.Everything is on-device, purposefully human-centric without being anti-AI. I built this because I wanted to work on a project that I could sweat the details unconstrained by deadlines, investors, etc.I was frustrated with other writing experiences, and like most I gravitated to Apple Notes due to simplicity, but I still missed so many things. As someone that's spent the last 2 years immersed in Cursor, Codex and CC, I wished some of their input behaviors existed in a regular text editor.For example, you can use / to add styles, or : to add emojis, shortcuts like < 3 for a heart, - > for an arrow, and so on. It honestly feels great.Is it radically different than other editors? I don't think so. But I think it's well executed across every dimension possible.Maybe one different thing: multiplayer. It's live editing like google docs, but P2P using WebRTC and strong cryptography. The limitation here is that you can only share a file while having it open yourself.Great care was taken to performance and portability. This is one of the areas where I spent a ridiculous amount of time simply because I enjoyed pushing the limits of the stack. While using you will notice that rendering, GPU, RAM and bundle sizes were heavily optimized. The Mac app is < 50mb.Very soon, I'll launch an iOS version with iCloud sync. In the future, I might launch basic AI features. If you miss a great text editor in your life, give it a try.

  I've been working on a cross-platform GUI system called Affiche.The basic idea is to separate an application's UI semantics from the toolkit that actually renders it. The same application can currently be presented using native Win32, Cocoa/AppKit, Qt6, GTK3, GTK4, Swing, or a web browser. The UI can run locally or be rendered remotely by a client, without the application itself being rewritten for that environment.I've also been working on a declarative layout format and, lately, a visual designer.It started as a rewrite of an architecture I worked on many years ago, mostly because I wanted to see how far the idea could be pushed with modern systems. It has turned into a considerably larger project than I expected.Still private and very much under development, but I'm curious whether other people have run into the same problem: maintaining applications that need to survive changes in GUI toolkits, operating systems, deployment models, or client environments.

  I'm working on a Zettelkasten notes app that focuses on getting the UX details right. It takes aspects of Notational Velocity, outliner apps, Zettelkasten, and wikis and combines them into an opinionated Mac app.What makes the app a little different from others is that it's kind of halfway between an outliner and a wiki. You can place notes in a tree hierarchy, but they can be free-floating as well. You can link to other notes using wiki-style text links, and each note has a unique address, so you don't need to give notes a title or a filename.Notes can even appear as a child note of more than one parent. The idea is that you can jot down an idea quickly without a lot of friction and then later either add sub-notes to create a note "tree" from it or add it to an existing tree. The tree gives structure to related notes, but the wiki-style links allow you to connect notes together outside of that structure. (I consider the tree structure a "hard" relationship and the links a "soft" one.)There isn't a single uber-tree where every note goes. Your notebook ends up with lots of free-floating notes and lots of small trees of organized notes, like a card-based Zettelkasten system. You can use search and various filters to find and stumble upon notes easily.Notes can either be stored in iCloud (so that they sync across devices) or saved in a folder as simple Markdown files.If you're curious, you can help beta test it.

  Updating a Rust renderer from WGPU 24 to WGPU 30. 640 lines of fixes needed so far, and more to do. I've fixed all the easy stuff, and now I'm down to reverse engineering breaking changes of excessive cleverness.I wonder if Claude Code could do this. That's a useful metric for the future - if a coding agent can't handle the breaking changes in a package upgrade, it's the package's fault. The day may come when that's something Github Actions checks for pull requests.

Slowly getting more customers.https://video-commander.comConstantly and carefully 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.Happy to answer any questions!

  https://tiny.helpI got so fed up with my support system, and after years of using tools like Intercom, I built my own platform with everything I've ever wanted in a support desk. The biggest upgrade for me was the MCP connection. I can pull down a ticket with a bug and solve it with Claude (or Codex) and get the agent to fix and then draft a reply in my own voice. It also allows customers to connect their agent to my support desk and ask questions. This would be agent to agent with a human in the loop. But the normal day to day stuff is mainly live support or AI enabled support.

  ChonkyBlox: A new approach to Block based coding - instead of complicated algorithms to derive the code from block programs I am using AI on the back-end, which actually makes a higher level of abstraction possible with the blocks. Each block has an LLM instruction attached, along with rules defined in the bespoke back-end harness.Also: kids can code using cardboard cut-out blocks and just take a photo to import, generate Arduino firmware, compile and flash to ESP32 - all from a single docker web application.Hoping to bootstrap a cheaper, open source alternative to current systems (one of which my son is using at his school). I have had success doing this with another project on Patreon so that's where it is going to be launched. https://www.patreon.com/ChonkyBlox - so far just a couple of demo video's but code will be released in full once I have added more blocks and a tutorial.Ultimately this is aimed at the South African education sector, where many schools may have only one computer available for a classroom to share, hence the cardboard cut-outs. There is also a hardware component still in development - a simple pcb breadboard break-out with connectors for components instead of kids having to use jumper cables on the breadboared. We also have a working Desktop application which does code assistance from within the Arduino IDE - using the same web server with api, so literally everything from very small kids to advanced is covered.

  I’m working on two projects that make public data easier to explore through maps.US Energy Cost Explorer (https://energy-maps.com) is a free tool for exploring electricity and natural gas costs across the US. You can compare states, follow prices over time, and look at bills and energy burden. I work in energy affordability, and I wanted to make this information easier for people to access and understand.MarketGround (https://marketground.io) lets you draw an area or choose a travel time around a location, then explore its population, income, housing, and nearby businesses. It also shows daytime versus nighttime population, which is useful when thinking about who might actually be around a potential store or restaurant during business hours.MarketGround is a side project, and I’ve found getting it in front of potential users harder than building it. I’d be interested in hearing from anyone who has evaluated a retail or franchise location. What information mattered most, and what was difficult to find?

  Still plugging away teaching kids to code and hand draw their own computer games:https://breaka.club/blog/why-were-building-clubs-for-kidsHave been running an in-school pilot over the last school term. Has been super insightful and led to a heap of changes to optimize UX. However, the biggest challenge has been delivery in this environment.Trying to run a game in a browser on school iPads powered by really locked down networks has been challenging. Some school iPads will crash (out of memory) when launching the camera view, whilst others run flawlessly. We use a fork of Godot, and are constantly fighting to strike a balance between UX (increased parallelism) and browser device constraints i.e. a limit on how many web workers we can fit in memory.In addition to our main (build and play your own RPG) experience, we also stream games direct to iPad. In particular a modded version of Overcooked! 2 that teaches kids to code — Overcooked itself was never even released on iPad. We've built our own Kubernetes system that spins up (a license limited number of) games/pods on demand backed by (time sliced) NVidia GPUs. This is literally running out of my home office. Despite the complexity of building all that, the Kubernetes and GPU time slicing wasn't even the largest hurdle. Turns out UDP is a no-go on the school network, so direct WebRTC was out the window. Instead we're using Cloudflare's TURN relay with TCP. Which much to my surprise, is holding up quite well.Definitely a learning experience. However, kids are having a blast. Can't wait to roll this out further!

  years ago i sat through interviews for front end & back end engineering roles at my old job while other folks were out (as member of a panel), and consistently I found that where we gave some real bugs to debug & fix, through a shared IDE, then worked together to solve it or go over the persons thinking, those situations we absolutely always got a better sense of how the person worked and solved problems & whether we'd like working with them or not (to some degree). I also found a few of those exercises to be educational myself.this year i thought itd be great to help prepare myself and other people in the job market with a tool that presented broken front end code, and then allow debugging on the browser and patch code right there, to test if it worked or not. if cant solve it, theres a nice explainer popup. my main hope is to help level up interview code chops and confidence in debugging just like we would on a real production system , at least the simpler bugs.still working on it, here's the draft of the idea: https://bugcloud.app

  Hey everyone!Last year, Mozilla released Orbit, an AI-powered browser summarizer hosted on a GCP server. After people started digging into the extension, they discovered things like backend endpoints such as store_result. Eventually, Mozilla discontinued the project. For the past month, I’ve been trying to rebuild Orbit from scratch, but with one major difference: Apogee is fully local and privacy-focused. Apogee doesn’t send or store your data. It can directly connect to your local Ollama instance for inference. I’ve also added WebGPU integration for Chrome and Transformers.js for Firefox to provide faster, local responses.It can summarize: Articles and websites, YouTube and Billie videos, Wikipedia articles, Hacker News and Reddit threads.You can check out the source code here: https://github.com/darshi1337/apogeeInstall Apogee:Chrome: https://chromewebstore.google.com/detail/apogee/pgemlpomhkdc...Firefox: https://addons.mozilla.org/en-US/firefox/addon/apogeeext/Obviously it is far from complete.

  I’ve been hacking on a single Anki extension for… the last three years now:https://smart-notes.xyzThe idea is to make an extension that allows you to flexibly fill out fields on your cards with AI generated text, speech, and images. Think generating example sentences for your entire deck, or adding furigana to kanji (small phonetic characters with a very delicate syntax). It works just as well for language learners as it does for medical students, etc.The secondary goal has been to make this the most well designed, intuitive, and stable Anki extension in the world. I don’t think it’s there yet, but it’s on its way. It’s been very interesting to try to work out a design that affords the flexibility to generate anything for whatever you’re studying but remains approachable and discoverable to your marginal Anki user, many of whom are younger and have varying levels of English ability. Many interesting technical challenges as well.Slowly building towards the Show HN post, but need a few more features. Connecting with and chatting with dedicated users in countries around the world over the last few years has made this the most gratifying thing I’ve ever built! It’s still at the scale that receiving support emails is fun and I can build relationships with power users and long term subscribers.

  I am working on an SRS based early literacy acquisition webapp: https://letterspractice.comThe app has recently moved into production, so I'd encourage anyone with verbal but pre-literate kids to check it out.The basic pitch is high efficiency acquisition of the highest yield phonetic mapping skills, and nothing else. I myself am something of a screen-time zealot and very wary of applying engagement mind hacks against kids. The narrow focus allows for good progress on a very modest schedule (recommended cap at n minutes per day for n years old, n >= 2). I defer the social and cultural aspects of learning to read entirely to parents.It is mostly intended for parent-child co-use, although kids with a bit of experience can drive many of their own sessions most of the time.

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 have our pieces in consignent in a jewelry store, and are working to put them in a museum store.Marketing is the hardest part.

  I’ve been working on Opslane, an open-source agent that identifies user-facing issues and investigates them.Traditional error trackers have two failure modes:1. False positives: They show you thousands of errors, and you can’t tell the impact on the user2. False negatives: Many user-facing issues don’t throw exceptions, so they go unnoticed.Opslane combines error tracking and session recording. And there is an agent that acts on both.Opslane reduces false positives by ranking issues based on how many users are facing a particular issue. It also learns about your product by reading your code and watching your session recordings.False negatives are harder. Opslane reviews session recordings to spot frustration. They look for rage clicks, dead clicks, and abandoned forms.Here is a link to the repo: https://github.com/opslane/opslane

  I’m building Hammer Labs (https://hammer.ai) to study when healthcare AI agents are wrong and when they should refuse to answer (judgement).It started after spending 15 years building AI for insurers, hospitals, data companies, and startups. Almost every system ended with "a human reviews the output". That person was usually a nurse, medical director, or certified coder. These are some of the hardest people to hire, and the same people automation was supposed to help.The problem is that real claims do not have an answer key. You cannot reduce human review until you can measure when an agent is wrong.Getting claims data is also difficult. It can take a year of data agreements, privacy reviews, and procurement. Even then, you may not know what the correct decision should have been. So we generate claims. Utilization and case mix come from published data. Claims are priced using real fee schedules and contract terms. Payers behave differently, like real payers do. We plant errors on purpose, so the correct answer exists before any model runs.On top of that, we are building benchmarks for overreach, refusal, errors by record type, and detection time. We are also building small MCP tools that refuse when evidence is missing. Every number includes its source, date, and basis.What I find interesting is how much of this sits between actuarial work and machine learning. Both are needed, but I do not see many people connecting them.25 published refusals: https://hammer.ai/worlds/refusals/ .Runs on rate and policy evidence https://hammer.ai/reimbursement-evidence/ and savings claims https://hammer.ai/savings-claims/ .AgentPlugin is Apache-2.0: https://github.com/hmmrlabs/hammer-plugin

For example, when I check website like irs.gov, ssa.gov and ups.com from Singapore they showed as down but it was only due to datacenter IPs being blocked.The second probe in Boston fixes this and the site can now say "unreachable from Asia" versus "down for everyone". Many of the existing checkers do not do this and they are prone to show false positives.Site does not use cookies or analytics. Pageviews are counted from the proxy access log. There are 634 curated sites so far.There are no ads either, it's mostly been for my personal learning experience, hopefully others will find it useful.There is even a free API and of course a MCP server.https://downforjustmeoreveryone.comAny feedback is welcome!

  I've been working on building hyper-local services, sort of as a love letter to my community in Denver, Colorado. Before decent LLM harnesses, these would've been prohibitively expensive in time and resources to build out and would never break even. Now I think I might be able to at least cover hosting costs and tokens; that's enough to keep these sustainable for my neighbors.Broomsday: https://broomsday.com sends folks emails and SMS the night before street sweeping parking restrictions for their block(s). Email notifications are free, SMS on a paid season pass. The schedule here is block-by-block and easy to forget, so people get ticketed _a lot_ at $50 a pop. The city has an email-only notification service that's free, but it's poorly supported and the interface sucks. This is ready; I'm testing with friends and family currently before attempting real marketing.HailPass: https://hailpass.com similarly is a notify-before-pain service that integrates a bunch of open weather services (NWS/NOAA mostly, plus a handful of impact reporters and working on a small hail-specific ML model) to give folks on the Front Range 5-10m heads-up before damaging hail arrives at their location. Weather prediction is (not shocking) hard so I'm still tuning to get as much signal out of the noise as possible; some false alarms will be unavoidable but I want to cut them down before even a F&F release. This year's season is pretty much over with, so aiming for an April '27 release.There's a lot of ski/snowboard/winter sport culture here, but there's also existing services for those, and I'm mostly trying to offer new coverage where there isn't a good option for my neighbors. Might do an ash borer treatment/prevention service navigator yet.None of this is going to make me wealthy or famous, but building things that help the people that I actually interact with every day and that are a part of a community that supports my family feels _really_ good.

  Totem is a collaborative workspace, featuring tasks, notes, and docs, built in Rust and available across desktop, web, and mobile (iOS to start) with seamless syncing and offline merge.I built this because I think there's a lack of true realtime (CRDT) synced notes that aren't built on a heavy platform that take up 1GB+ RAM (Totem takes up ~100MB, and is also generally more responsive due to the local-first + ops-log approach).Another thing I care about is keeping the underlying data portable: Totem is built on Markdown and SQLite as its core formats, so you get the convenience of cloud-based syncing without locking your data into a proprietary format.I’m still looking for beta users/design partners before the initial launch. You can try it without creating an account here:https://app.thinktotem.com/sandboxAnd the landing page is here:https://thinktotem.comThis is a bit of an unplanned post, so the sandbox template is a bit barebones (empty docs, doesn't feature a properly setup table). Nevertheless, I would love to hear your feedback if you try it out, especially if you use collaborative notes/docs today and have opinions on what they’re missing!

  Iterating through and evaluating possible approaches for shrinking the binary size of a tree-sitter based Vi/Vim compatible tags generator I am developing without affecting the developer experience for adding support for newer languages[1]. A couple of approaches have already been tried and failed to live up to the expectations on developer experience [2][3]. Next in line is to look into bundling only the tree-walking code for all supported languages with tree-tags and allow the user to configure the grammars to download separately from the main binary, possibly using the `wasm` feature which allows native library to run wasm compiled grammars.[1] https://github.com/jha-naman/treetags[2] https://github.com/jha-naman/treetags/pull/62Tried to use a generator for automating the bulk of the scanner for a language from `grammar.json` file of a tree-sitter grammar. A runtime engine uses the scanner for a forward only walk on the scanned code and calls the hooks to generate tags.[3] https://github.com/jha-naman/treetags/pull/56A complicated mess of a generator that takes a few declarative inputs and tries to generate code for spitting out tags for a given language.

  working on a storytelling app for kids called Tella Stories that goes deeper than just some minimal personalization.. know there's lots of stuff that claims to make them the hero, yadda yadda but then they just give you a shitty digital templated story or try to sell you a printed version. this is focused on a high level digital experience and something parents can actually trust, and that kids actually enjoy.so yeah.. it builds the stories out of their actual life. their family and friends are in the cast, their dog, the thing they're nervous about this week. the kid doesn't just appear in the story, the story is about their world and imagination and grows with them.ultimate goal is to keep iterating and get to a level of quality of Bluey, etc but have it actually be the kids world with agency/choices vs. one they have to passively sit back and watch, and that they're not in.would love any feedback. i know there's been others like Ello shared on here and those threads were really interesting to know HN's opinion on. this does not take an educational and instructional approach. Tella is meant to help develop who they are through stories and be a better screen alternative time to the rest of the algo/curated garbage out there. anyway you guys are a critical and technical bunch and i respect/appreciate that.. especially since this of course leverages multiple AI services to create the stories ~https://tella.kids/

  I'm making an online guidance solver for KSA (https://ahwoo.com/app/100000/kitten-space-agency). It will allow you to control a KSA rocket from the command line for a variety of maneuvers (launch, rendezvous, etc). It uses successive convexification to turn the full nonlinear problem into a sequence of convex problems with linear constraints and quadratic objective.It has proven surprisingly resistant to AI so far - Astra can make a very quick prototype but upon review it had many defects. I have had to guide it very thoroughly to find all the random solver bugs (bad conditioning, formulation, bugs in openscvx which I had originally had the AI port to rust, etc.) preventing well-behaved solves. But I think (hope?) I have turned the corner on these.This will enable some very interesting further experiments: full mission planning, Falcon-9-style ascent with split control, vehicle swarms, etc.

Post an open problem with your current investigation. Another agent may be able to solve the problem, and will have a head start thanks to your context - Solutions can be linked/edited/have addendum added by any agent, allowing complete, up-to-date solutions for a range of cutting edge issues

  I'm working on a p2p streaming/sharing app called bubbleBASED. Its here https://bubblebased.com/ its based! on bubbles! But it uses Webtorrent to stream and share content in context bubbles. You already need peers for a social network—so why not use those same peers to seed the media? like a closed loop and it cuts out AWS because everyone is a peer for everyone else in your bubble. There is an assist from Heroku and Pinata. There is no algo. Its just whatever you post. Also you can add an affiliate link (from cj.com) and it will pop in a platform ad for you so there is a revenue possibility there. The streaming part was intense - I built this because I wanted to see if browser-to-browser streaming could actually work for small, private groups. The broadcaster records via MediaRecorder, chunks every 8 seconds, seeds each chunk via WebTorrent, and viewers assemble them with MSE (or ManagedMediaSource on Safari). There's a server-side "always-on peer" so streams don't die if the original tab closes.The interesting problems were: MSE on iOS Safari, chunk continuity across peers, and handling rotation metadata that iOS bakes into the video stream. Also, the tracker is a separate bittorrent-tracker instance because the built-in WebTorrent trackers are unreliable for sustained swarms. Also i used a ton of graphql, so normally with a torrent you have to kind of let people find you but i used a graphql subscription to TELL people what the magnet links were called so they can fetch them asap. Lots of shortcuts like that, its been interesting!!

  Recently:- I've been tweaking a bot that I built to doomscroll job boards for me, to recycle more parsing logic between target sites. It turns out that, much of the time, I can cut down on DOM-based scraping a lot by just parsing schema.org-based JSON-LD. Also casually researching vanilla Web components, view transitions, and Signals in a general effort to make the whole thing less framework-heavy. (Plus it will have side benefits to building the crawlers to have a better understanding of light vs shadow DOM.) Eventually I need to get to figuring out how I want to handle distributing this local-first app across multiple clients... I've been putting that off for a while, but it kind of crosses over with the JSON-LD thing, in that (even more than it did before I found this) it also just makes a lot of sense to use a browser extension to collect potential matches passively.- 3D printing experiments. I got a used SV06+ a few months ago that turned out to be a lot more finicky than is suited to a first time user... but that was in the course of trying for several months to make plans with a friend that was getting rid of her Ender -- which I then managed to resurrect using all the cleaning tools and tinkering research that I put into my fussier machine. I've since been toying around with a lot of different ideas on how to clean up my workspace and/or fix/reuse stuff I have already (parts trays, Skadis panels, a case for an old Framework mainboard, various instrument stands...) and also toying around on paper with what kinds of printed items I might be able to sell.- Starting on cleaning up a basement that resembles the Research floor from Control. Also a use for the printer, because if I can just print cheap tools out of PLA then I don't have to care about possibly needing to sacrifice them to the mold.- Various Coursera stuff. My state has some partnership with Google for "AI readiness" training, that grossly undersells the various other adjacent topics offered, ranging from cybersecurity to marketing and eCommerce. Stuff where it may be a relevant topic at points, but isn't the subject matter.

It's quite fun and inspiring to see some of these assets like textures and geometry that are improperly decompiled, bit shifted or something like that. produces a lot of abstract, glitchy art.To make sure that my process and results are reproducible, I've gotten back into maintaining Concourse CI pipelines. They were very useful when we were shipping a fork of k8s for VMware, and now they are a fun way of shipping cyberpunk billboard sprites to Cloudflare buckets.I got back into Concourse in order to attempt a more rigorous approach to generative AI experimentation as well. Unfortunately, there are just so many odd techniques, configurations, loras, and utilities striking my fancy that my experiment pipelines have exploded into the dozens, and Concourse is not a large enough or a high-level enough organizing principle.

  I've been working on a collection of native AI/ML operators for TouchDesigner on macOS. Think of it as a happy marriage between the interface of TouchDesigner but with some of the features you know from ComfyUI.https://www.patreon.com/MickeyvanOlst/posts/meet-aml-macos-1...Typically TD for the Mac has always been a bit underserved, by leaning into some of the frameworks that exclusively exist on macOS I'm hoping more people will see it as a viable platform for this kind of stuff.

  https://solanda.federa.socialA new UI library made with zero dependencies (native web components). I just made it public as I actually use it for my personal projects since past year.The core principle is to help with UI development without bloating a project. It works with vue/nuxt (tested, my projects are done with it), but also react/angular/svelte/etc.One feedback I got from reddit (I published it this week there) is that AGPLv3 may be a problem for adoption... still not sure if should I use MIT.

I've got pretty much everything working really well, and the main thing I'm working on is improving the UX for all the workflows I do most often. It is mostly built around what I wanted from the tool, but before I release it I'm looking at supporting various other ways people use the tool. It's been a fun project so far.

  I haven't been working on it as of late, mostly because i'm a bit deflated from software in general, but I started working on a programming language I called Grasp.If lisp is a list processing language, grasp is a graph programming language.The idea was that most other data structures can be represented with a graph ( adjacency matrices are matrices, a tree is a type of directed acyclic graph, a list is a graph where each node connects to at most two nodes, etc) and so if you designed a programming language where the language is itself a graph, much like how lisp is itself a list, you could get other esoteric programming languages like APL, forth, lisp, and so on as DSLs of Grasp. Also any program you write would be its own CFG.I started it but honestly its mostly a hot mess of vibe-coded garbage. But I may get back on it and try to clean it up.

• seanmcdirmid
  I'm further along in my funemployment project:https://github.com/mcdirmid/cleanroomSo far I have bazel macros up that can produce tested code with a ~30GB MoE model (Jundot/Qwen3.6-35B-A3B-oQ6-mtp, I can get ~90 toks/sec on a M3 Max!) using cleanroom separate implementation and test development (and then comparing them until both are correct). Over the last month, however, I found that my bottleneck is in the specifications: as I further divided my components into separate parts (since smaller components are easier to write and test), I started hitting problems with specifications becoming badly ungrounded (code depending on knowledge they cannot access, so something is just hallucinated).So I redid the format, e.g.https://github.com/mcdirmid/cleanroom/blob/main/update_with_...The spec format is designed to be declarative and very modular, and ya, an LLM is primarily writing the specs as well, so I hope to create some sort of formal reasoning framework that the specification can be translated into (by an LLM) so that ungroundness feedback can help the LLM write better specs. Also, I found that it really is much more robust to change/refactor/add features via the spec first and then align changes down to test and code, then to make changes to the code directly (even without using the system, just asking a frontier model to look at the guides and do the alignment itself directly).I think I'll be ready to do a release over this next month, which means:- Supporting a build system other than Bazel to express DAGs. Honestly, this could be anything, I just chose Bazel for convenience (easy to express graphs in Starlark), but it assumes a monorepo world that I don't think many developers use.- How do I even package this? The advance of using Starlark is that I can generate python code to call into the generated python code directly. If I move away from that, I need to figure out what this really looks like as a binary.- More demos. Right now my only project is the code for the system itself (the classic "the first program of a language is the compiler for the language"). I just can't think of many interesting things to do in Python that aren't agent related (I can support other languages, like Java, Typescript, or even C++, but I'm hitting choice paralysis).

  I'm working on SpecPilot (https://specpilot.dev), a spec-driven development layer that sits in front of Claude Code, Cursor, Copilot and the rest. It deliberately doesn't generate code. It scaffolds a .specs/ folder and hands the actual writing off to whatever agent you already use, so the specs become the thing the agent is held to instead of a prompt you retype every session.Open source, free, no login, nothing to sell. I'm not trying to build a business on this. I just want agents to write better code, and that only happens when they have something firmer than a chat prompt to work against. CLI is here: https://github.com/girishr/SpecPilotIt started as a TypeScript CLI in January. Enough people told me they either didn't want a CLI or didn't know how to use one that I rebuilt the front door as a guided chat: 27 questions, runs fully offline in the browser, outputs the .specs/ tree plus an onboarding prompt for your IDE.Recently shipped an MCP server so the agent can run the questionnaire itself rather than the human doing it, published to the official MCP registry and Smithery. Next is brownfield: point it at an existing repo and backfill specs from the code. Honest state of things: the Product Hunt launch got 4 votes and around 100 visitors, and I had no event tracking wired up, so I couldn't even tell how many of those generated anything. Fixed since. Usage is small but real, and it's coming through MCP rather than the web app, which I did not expect.The part I keep circling back to is that spec generation is easy to copy. Spec enforcement is where the value is: checking a diff against the spec and failing loudly. Feedback welcome, especially from anyone who tried SDD on an existing codebase and gave up.

  Lots of things really:1. Aetheris: geometry CAD kernel, https://github.com/yuechen-li-dev/Aetheris/.Full code CAD capability with big coverage already and some functionalities that even OpenCascade/Parasolid/ACIS doesn't have, full sheet metal module, programmable part assembly, analytical fillets/chamfers, mathematical knots, auto-route for piping, built-in finite element analysis, etc. Had Astra make an improved version of the V8 demo that was going around on LinkedIn, so it can do general hard surface modeling pretty well too, turn all the Astra demo prowess into reusable capabilities/templates. The DSL is human writable too, so give it a try if you want. https://aetheris-editable-v8.yuechenli.workers.dev/2. Concept language: https://github.com/yuechen-li-dev/ConceptI've said before that Carbon isn't a real programming language, never mind a successor to C++, so I decided to put my money where my mouth is. The idea of it is to be more TypeScript to C++'s JavaScript and to generalize C++20 concepts from template constraints to what C++26 is doing with contracts, and bring the equivalent of Rust's borrow checker to be opt-in by default instead of opt-out, fast compile time, in a syntax that C++ users are already familiar with (`const auto` instead of `let` for example) as well as templates and comptime. Language is done-ish, not self hosted yet, still compiles to C11, kernel and allocator libraries are finished, currently working on the scheduler right now.3. Copeland TS, https://github.com/yuechen-li-dev/copelandTypeScript for .NET without all the weirdness of Javascript, with full Nuget and NPM inter-op, Rust style exhaustive `match`, templates, etc. It's actually weird how much cleaned up TypeScript ended up looking like cleaned up C++. Compiles to JS, C#, WASM via Blazor WebAssembly, and SPIR-V via HLSL/DXC, and runs on V8 for JS and RyuJIT/NativeAOT for C#. The conclusion is that RyuJIT ended up being ~2x faster than V8 JS in hot loops but the cold startup time is higher, so replacing JS for UI really isn't worth it. Comes with full UI layout system, Vulkan renderer, and game/app runtime, but those are still pretty rough.

  I've been doing a bunch of stuff with using a PUT[1] to simulate an IF (Integrate and Fire) neuron[2]. Right now I'm experimenting with variations of pulse-width and frequency of the input spike train, seeing how that affects when the "neuron" fires. In a future step I'll add a resistor to bleed off some of the charge from the timing capacitor, to make it more of a "Leaky Integrate and Fire" neuron.And then ... well, we'll see. I'm also reading a lot of books and stuff on neuroscience, neuromorphic computing[3], analog computing, etc. I don't have some "grand unified theory" or anything, just playing around in this space.There's a lot more I could say about this, but I'll save that for a blog post or something. That said, if anybody wants to see some pictures and read some write-ups of some of this stuff, add me on LinkedIn[4] and you'll see some of that stuff in my activity there.EDIT:What the heck, here's a picture for anybody who's interested.https://fogbeam.com/images/scope_20260913_202613.pngThe magenta trace is the "spike train" which is output from a Rigol DG4162 Function Generator. The yellow trace is the voltage at the anode of the PUT, which simulates the "action potential" of the neuron membrane. And the cyan trace is the cathode of the PUT, which simulates the output of the neuron. What we see here are several input pulses hitting, with each bumping the action potential up a little, until it finally hits a threshold and then "fires" and resets.

As part of the DNA purification task, I had to journey up to Healdsburg to buy some lysis enzyme (thank god for winemakers, 100x cheaper than the biotech grade stuff), and noticed catalogs of different yeast strains with all their flavor profiles and stuff characterized.I'm thinking about buying all the strains and pushing them through my automated sequencing pipeline, and building a yeast genotype -> flavor converter. Then, I think it'd be neat if you could have someone try a bunch of wines to get their favorite, and then genetically engineer a yeast strain specifically for their favorite flavors. Think that could be neat.

  https://topicle.com/A social media platform trying to solve misinformation, astroturfing and inauthentic posting. I also thought there was a real space for some non-US-based social media, so this is based in Australia. This is owing to all the political instability going on in the US right now and especially stuff like users' identities being subpoenaed for criticising the government. It was a pet peeve of mine seeing threads of comments that are obviously artificially created to push some kind of narrative, and the ability to buy likes and upvotes to shape opinion. Nothing ever seems to get done about it on big platforms, so I wanted to make some small contribution towards fixing it. And there's an element of self-interest here, because I want to be able to read a platform where every comment is authentic.I've been working on it since 2023 and launched in March this year. Recently, native mobile apps have been launched. It was also an experiment in seeing whether Swift Vapor can be used to build a complex backend and the answer appears to be yes. It's a lot of fun to see how bad actors are joining the site, then building automated mechanisms to counter them, using AI to improve detection, without impacting legitimate users. It's also been a great technical challenge to try to support features that the big players support, like video upload and encoding, image upload, CSAM detection, NSFW detection, LLM-generated text detection and auto-translation using DeepL.There are also lots of legal compliance challenges now with age verification laws coming in around the world, and ensuring you employ all the correct Apple and Google-specific verification (Declared Age Range, Play Age Signals) in the correct global regions. It's also fascinating to see behind the scenes how tight or not so tight current age verification actually is.Recently, I've been polishing the iOS version to try to hit the 120 Hz target frame rate while scrolling feeds and finding SwiftUI is much less capable at this than the old UIKit approach. I'm also trying to teach myself marketing and how to keep users engaged. I'm primarily code-oriented and historically haven't had to do any marketing myself, and this is a vertical learning curve. I have gained a great deal of respect for those who have 'figured out' marketing, seeing how difficult it is starting from nothing.It's also satisfying to take a feature from a user suggestion in the morning to an app release including that feature in the evening. This is a speed of delivery that would be unthinkable in the corporate world, where I previously worked, and it's very gratifying to put a complete feature in a user's hands within 24 hours.Anyway, it's a very long and tough road and may amount to nothing in the end. But if nothing else, it's been immensely educational and enjoyable.
