  My one-stop shop combining Letterboxd, Goodreads, Vivino (basically anything).You use it to 'rank' any abstract entity you choose. The idea is that you'll be able to find common things you like across categories (I think the type of books you like probably influences the kind of movies you like!)https://rankr.click/

  I just (vibe) coded up a little block training app for skateboarding. I noticed that the vast majority of skaters don't land anything consistently and just huck their skateboard around. Unlike in other sports where people follow some sort of progression most skaters never learn fundamentals or practice in a logical way. This is my solution to that using modern block training, progression gates, and tracking methods. This is still a tiny MVP:https://blainehodder.github.io/shredlog/

  Working on https://croncoco.io/, an api first scheduling and orchestration platform. This is my first attempt at a paid microservice build, and yes I will admit it is similar some other services that are already out there, but, I still had a ton of fun building everything that goes along with designing and building a small microservice!https://croncoco.io

  I continue to work on my city builder game Microlandia, launched here in HN ~6 months ago. I originally predicted a few dozen urbanism nerds would play it, but now almost 10,000 copies sold. I'm still a solo developer but now I collaborate with 2D, 3D and music artists. Which is good because the original art that I drew myself for the launch was horrible.I'm currently working on modeling energy, climate and new policies like universal basic incomehttps://microlandia.city

  Recently finished building cotect:https://cotect.devIt's a fast code inspector for agents so that you can easily verify changes before they end up on GitHub and also quickly move around the codebase to keep its shape in your head (to make sure your prompts stay high-signal).

  Been learning electronic PCB design the last few weeks while retrofitting some IKEA window shades for Zigbee enabled motorization.I've really enjoyed the journey of 3D printing and being able to create all kinds of mechanically useful things over the last few years, but I had always wanted to go even further and incorporate some non-trivial custom electronics.For this project I had a space constraint for the motor controller board, so while I could have probably hacked together a working perfboard, it just wasn't going to be satisfying. So I finally took the plunge and spent 40 or so hours in KiCad learning how read IC reference documents, picking components, and of course, doing the PCB trace layout.It's really just a 12v→5v buck circuit, all the plumbing and ancillary components for connecting a ESP32 module to a couple motor driver ICs, and some headers, but it is completely mine!Just got 5 of my boards in the mail from JLCPCB the other day (insane turnaround, less than a week) and was very happy to find that the entire circuit worked perfectly! I did spend a fair amount of time going over the design with Claude though, so I think that paid off (the kicad files are plaintext, so it made easy work of understanding what I was doing).Still putting together the repo here, but I'm hoping to make a little blog post out of the project too :) https://github.com/evanpurkhiser/HOPPVALS-MRF-01

  I didn't like how diagram making apps were built so I developed https://grafly.ioI also vibecoded/built https://github.com/lnenad/difiko as AI generates a lot of code that needs a nice way to review it.I'm also in the process of preparing a soft release for http://logdot.io as the market has no access to low friction logging/observability platforms.

  KiCad web port, with real time collaboration. I've been working on it for the last ~6 months on and off, I have some help now. It's close, we're launching in a few weeks ( hopefully this one ).It was an interesting project since there were so many unknowns, like can we really turn an offline desktop app into a collaborative one, can it be fast enough, can we port the graphics parts. It turns out you can! I have a semi-vibe coded landing page now, you can sign up to get into the alpha cohort: https://www.pcbjam.com/

  I’m continuing to work on my daily word game Tiled Words!https://tiledwords.comI checked my analytics recently and over 100 people have 100+ day streaks which kind of blows my mind!I released custom player puzzles which has been a lot of fun! I’ve gotten dozens of submissions that I’m working through. People are submitting really clever and interesting puzzles. It’s fun to get to solve puzzles I didn’t make myself! There’s more I want to do here (featured puzzles, categories, etc.)https://tiledwords.com/player-puzzles/page/1I think I’ve also tracked down an issue that was causing the game to crash on older iPhones. I’m having playtesters run through it now and hope to deploy tomorrow. (Switching some positioning rules from CSS transforms to SVG coordinates)I recently made some puzzle brainstorming tools using the Datamuse API which have been very helpful for brainstorming words related to a theme.I’m starting to debate some monetized features. So far everything is free but it would be nice if my wife and I could dedicate more time to this. If I could get a few thousand dollars a month in subscriptions my wife could quit her job and focus more on puzzle creation and improving the game. If you play and have ideas for features you pay for I’d love to hear them!

  Actively working on https://thatbook.club (https://thatbookclub.com). An idea I had for me and my friends, and which we have been using for the last 2 years privately. Just made it open for others to join in.Similar to goodreads and other book clubs, but focuses on making logging pages and statistics around your reading more fun. Nudging friends when logging pages is the main motor behind this.

  I'm working on Hiring Method (https://hiring-method.com).After 1.5 years of development and two exhausting pivots, I’m incredibly happy to finally have our v1 live!While most of the HR tech is rushing to use black-box AI, I built the exact opposite. It's a transparent, math-driven fitness engine. It extracts objective data from CVs and calculates how well applicants match requirements, letting you see the reasoning behind why someone scored an X%.If anyone here builds in the HR space or regularly hires engineers, I would absolutely love your feedback or a roast of the landing page.PS This is a project of immense importance for me, I've been working on for past ~2 years, I'd appreciate to know why this comment is flagged.

  For the last month I've worked on a firefox plugin that allows me to send webhooks to my home assistant.In my living room I have a linux pc connected to my TV and I'm using this in 2 ways:- Automatically set lights when media starts/stops playing. This way I can turn on some accent lighting when I pause a movie to go to the bathroom and automatically turn them off when I resume the movie- When media is playing I calculate the color that best represents the content and export it to home assistant use it as a poor man 'ambilight' with a led strip strategically placed behind my TVI think the next logical step is to find a way to automatically track the content I'm watching so I can have some high level stats about my viewing habits.

  Still plugging away at Breaka Club, where kids take photos of their hand drawn art and build games using it. Starts out as no-code, photograph an AprilTag and it imbues the image with functionality.https://breaka.club/blog/why-were-building-clubs-for-kidsWe also teach kids visual scripting in Overcooked 2!, allowing kids to code their way through the levels of an existing much beloved game:https://youtu.be/ITWSL5lTLigI'm running an in school pilot this week (Lunch time school club).The tech stack for the main product is honestly pretty intense at this point with full multiplayer support, offline play, transitioning from client authoritative to joining a remote server. Built atop GodotJS, TypeScript bindings for Godot, which I maintain. Huge monorepo with over a million lines (yes, I'm aware that's NOT a good thing), and GodotJS itself is not included in that.

  I am making Cargo for C. I have 3/4 of a working demo; the tool can build itself, including some non-trivial dependencies which I've ported to build natively with the tool (instead of wrapping their Make or CMake or whatever).The pitch: It's insane that we have to pull in Python or Lua to build C code. CMake is an abomination against god that has become usable in spite of itself. Zig cc is proof that this entire ecosystem is an embarrassment. My tool gives C projects a TOML manifest, and builds scripts written in C and JIT compiled by the tool. Now, you can write build scripts in the language itself, pull in dependencies you wanted to use anyway.It also provides a stable ABI. There's an HTTP-backed index and a Git-backed index. And it generally does the same thing for C that, say, Bun did for JS/TS. You'll be able to run C files from source and have the entire ecosystem available. You'll be able to trivially generate single file static binaries, or dynamically link to an older glibc without arcane tricks. It will fix C.I'm also still working on my "what if we wrote a real standard library for C"; I added some feedback I got from the release.https://github.com/tspader/sp

  This is the first year I made more money selling art than I did freelancing web dev. I just incorporated and formalized my web dev business (https://lcdbmg.com). A couple of weeks later I got a booth at an art festival and ended up selling many prints (https://lucidbeaming.com). I think the universe is telling me something.

  My wife and I are working on a math/science/CS-inspired jewelry business.We try to create pieces that stand on their own aesthetically but have a hidden meaning. 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).Store: https://studio-galois.com/

  After getting the top spot in What Are You Working On in Feb 2025 ( https://news.ycombinator.com/item?id=43157056 ) I started a company on that idea at https://getcomper.ai . After solo building for 11 months I found a co-founder, got an angel investment, then got some ex-Miro folk on board and we are now building the product at breakneck speed.We're a collaborative canvas + context engine for all the code and docs in your company, with a zoomable UI + CLI , where you can collaborate with your co-workers and agents.We map technical debt, agent readiness, code complexity, security scanning, bus factor and more, so you can easily see how all the software in your company runs.One of the most complex things is our incremental git blame engine built on top of GitOxide, as our backend is fully built on Rust. Our frontend is built on PixiJS so you can explore at gaming speed with 60Hz refresh rates.Recently we sponsored Rust Week in Europe and a hundred or so developers tried our mini-game which is GeoGuessr for code, and got rave reviews. Future is looking bright!

  I'm finally fulfilling a childhood dream of restoring a Heathkit oscilloscope. I managed to nab a functioning IO-12 at the thrift store for $75!Don't tell my husband that I spent more than $200 on parts and supplies for it.I've wanted a Heathkit since I learned about them as a teenager, and this is the first one I've ever seen in the wild. The original owner left the date he assembled it and his callsign written on the inside! I looked him up and he died in 2013, but by sheer happenstance I'm restoring it 58 years to the day that he initially built it. I got super lucky with this unit because as far as I can tell, it's only been run a few hours in its entire life. I really only have to replace aged components because they're physically breaking down, I expect the thing will outlive me once I'm done with it. Can't wait to hand it off to a bewildered young EE in another half century.

  Still working on GhanaHousePlanner, we have integrated a robust cost estimator based on geometry of the house generated from the floorplans, this has allowed us to achieve very good results for the estimated cost by factoring in lots of inputs that would have been complex to handle since we generate the plans on the fly.We are currently expanding the architectural drawings and structural analysis and also export formats. The goal is still to offer everyone in tropical countries the tools to understand their house construction before they go to meet professionals.https://ghanahouseplanner.com/

  Long time ago I got tired of all the worthwhile weightlifting apps wanting a monthly payment for full feature set while delivering an uninspiring, cross-platform experience.Out of my love for weightlifting and iOS native apps I began building Plates as a one-time purchase for the full, premium experience.

  An offline-first app to make life a little easier for someone I love and her caregiver. She's been diagnosed with stage 3 pancreatic cancer and food has been a bit of a nightmare for her. Her partner is also not very skilled with cooking, so helping them make this easier is my gift to them. Not a medical device, just a food logging and logistics tool. The privacy aspect of this is very important, soI am so careful not to let anything not heavily encrypted touch a network request. Sync is opt-in, offline is default. This is very challenging for me, but I want to help her the best way I know: building software for humans.

  3 hours trying to remove an oil filter from tractor. Chain clamp mishaped it, I ended up shredding it, ripped out the innards, all the tin down to the intake rim (yes, shredded metal everywhere) until finally used needle nose spread open in two of the intake holes and a plummers wrench for torque finally loosened it.Reading Brand's quick little life changer kept me going with surprisingly few cuss fits:The Maintenance of Everything: https://search.worldcat.org/title/1511798465Thanks, Stew!

  [NO-AI]My wife and I continue to work on Uruky [1], a simpler Kagi alternative, based in the EU.Last month we launched image search (got out of beta this month), added our own index and crawler (via Uruky Site Search [2]), and reached 100 monthly active accounts (we’ve passed 150 now)! You can also see a privacy-focused independent blogger wrote about us [3]!!You can check out the main differences between Uruky and Kagi, DuckDuckGo, SearXNG, etc. in the footer (right side), but one huge difference is that with Uruky, after being a paying customer for 12 months, you can download a copy of the source code (licensed as BUSL into AGPLv3 in 2 years — a suggestion made here in HN)!You can also now get a free trial for 2 hours when you signup if you pass a proof-of-work captcha (another suggestion made here on HN, and it uses a local Altcha).Our main challenge continues to be discoverability and outreach because we want to do it ethically. Ideas are welcome! We’ve been sponsoring open source projects, open source maintainers, and indie, small-web, and privacy-related websites and applications.Feature-wise, for June we’ve already added a ton of personalization and privacy-increasing features like URL rewrites, cash-by-mail payments, and anonymous vouchers! Upcoming is partnering with ProxyStore to sell vouchers (we’re currently in talks for this), so you can buy vouchers with XMR/Monero or other cryptocurrencies. Then we’ll be looking into increasing our own index, focused on indie/small web.Thank you for your kindness![1]: https://uruky.com[2]: https://uruky.com/site-search[3]: https://theprivacydad.com/interview-with-the-engineer-of-uru...

  I've been working on releasing an app for maintenance tracking for home. I've always had problems with having in my calendar to replace a battery in my chicken coop every year, then things come up and I end up replacing the battery a few weeks later, so I have to go and change my calendar event. Or fertilizing my hops every two weeks only in the summer. Then in the winter I am getting notified every two weeks. So I built a simple app for tracking those with floating repetition and seasonality. [0]Also recently got a lot of home VHS tapes digitalized and always had trouble with playing from Google drive or finding the right video. So I just built a webapp this month to split the videos into clips, transcoding it for better streaming, Google casting support, and tagging for search.

Infinite scale without having to add 100 front-end UI frameworks: simple Python, CSS, and JS with SQLite. The design is absolutely breathtaking and beautiful and it is built people first (let's worry about scale later).- Simple LLM: an LLM which doesn't need a GPU to function. It uses Hebbian learning with extreme compression and attempts to achieve 'reasoning ability' through using a in-built Prolog interpreter. It very much resembles a human being in it's 'thinking mode' so far but still far from perfect.- Simple-Education: local first software for parents looking to provide home-schooling for their children. It makes learning easy and fun and uses best practices to maximise your child's chance of success.- About a dozen other projects which I've started but I need help on.

  I fell down the rabbit hole of voice transcription about a year ago, always had a love for utilising fine tuned LLMs so have put two and two together and built https://whistle-enterprise.com. The biggest challenge being it all running on CPU with the target device being your low to mid spec office laptop that's a few years old (I5, 8gb RAM). All nicely packaged together in a single completely offline selfcontained app that you just install and run (no environment setups, packages to download, models to download etc).One of the hardest parts I've found is the diarisation (who said what) side of things. Trying to tune this and have it working in a way that doesn't absolutely grind the laptop to a halt or take forever to complete has been _hard_ but also extremely rewarding.Another part has been the fine tuning side of the Phi-4 model, I'm on version 10 now, getting that pipeline down was a journey in itself, but I've got some great results. I wrote a bit about it in a comment here - https://news.ycombinator.com/item?id=48385906#48389625I absolutely love working on this, I still wake up and the first thing I think about is voice transcription pipelines (sad I know), but I'm excited to see how much further performance and utility I can squeeze out.

  In reaction to recent AUR supply chain attacks, I am working on two small tools to try to help address the issue for myself.First, `aurgate`, a small AUR helper which is more barebones than alternatives but provides a "full diff" workflow. The idea is to make upgrades feel like a "full diff review" and also support graphical tools like meld or the vs code diff viewer.Second, `flatgate`. This tool is inspired by LittleSnitch and Flatseal. Here the idea is to "default deny" all permissions of newly installed flatpaks and allow/whitelist per invocation (where possible) or on first use.

  During my 45 min commute to work I listen to podcasts. Over the last year, like most here, I have been focusing on AI and agentic engineering. The podcasts that I enjoyed the most profiled research papers.In April I started playing round with generating a semi-automated pipeline with python and Claude to generate a private podcast that does a deep dive into AI research papers. I think it is really cool. It fetches papers, scores them based on novelty, importance, relevancy, etc., and then writes the podcast script. It then generates the show by using Eleven Labs voices and then puts it in an RSS feed that Apple Podcasts is ok with.My personal expense for generating this stuff is a sunk cost, so in May I opened it to everyone via https://paperdive.ai/ It was really fun working with Claude 4.7, 4.8 and even Fable 5, to make the site and refine the pipeline. Now I put out about 4-5 episodes a day. I listen to each one first, then promote the "staged" episodes to my "prod" feed.This weekend I just add weekly and monthly reviews. Claude will write the review and another instance will generate a script the converts the review into something (hopefully) easier to listen to.Here is last week: https://paperdive.ai/review/weekly-2026-06-14.html And here is the review for May: https://paperdive.ai/review/monthly-2026-05.htmlNow, during my commute, I listen to the individual episodes and the reviews - I typically run them at 1.5x to 2x speed. I have become a much better user of the AI tools by keeping up with recent research.

  I'm working on steganographic storage and file encryption tool.tird /tɪrd/ (an acronym for "this is random data") is a steganographic storage and file encryption tool.With tird [0], you can:1. Encrypt file contents and comments with keyfiles and passphrases. The encrypted data format (cryptoblob) is a padded uniform random blob (PURB): it looks like random data and has a randomized size. This reduces metadata leakage from file format and length and allows cryptoblobs to be hidden among random data.2. Create steganographic (hidden, undetectable) storage (tirdFS) inside container files and block devices. Unlike VeraCrypt and Shufflecake, tirdFS containers do not contain headers; the user specifies the data locations inside the container and is responsible for keeping those locations separate. Any random-looking region of a file or block device may be used as a container.3. Prevent fast access to decrypted data using time-lock encryption.4. Use additional tools: - Create files filled with random data to use as containers or keyfiles. - Overwrite the contents of block devices and regular files with random data to prepare containers or destroy residual data.

  I have been working on, Dhee an AI Video Orchestrator. The main problem with creating AI Videos is that it takes a lot of different tools and co-ordination. What if we could have a expect curated repository of workflows for creating AI Videos or Comics or Music or anything digital honestly!!!That is why I created Dhee Desktop / Dhee Core ( Open Source https://github.com/dheeai/dhee-desktop https://github.com/dheeai/dhee-core ) - which allows anyone to author and run their own workflows for creating AI videos. Its local first, fully customizable, private runner for your workflows or any kind of community provided workflows(bundles) too (Comes with a few built in bundles to generate a full multi-scene segment just from story! ).Its not just a workflow runner, but rather comes with an AI agent to manipulate the generations. AI images and video models often make mistakes ( extra limbs, wrong face etc ), You can ask the Agent to make changes to the prompts, trigger a rerun, Completely change the character and only trigger the exact shots in which he/she appears etc. It knows and tracks the dependencies.My mission is to make it super easy for anyone and everyone to be able to create AI videos that they want to watch. I am envisioning a future where you make your own movies and watch it on your PC / TV rather than wait for someone else to make a movie that you want.You can check out how it works on https://dhee.studio

  I'm working on Glyph, Its a is a statically typed functional language in the ML family.Surface syntax is mostly SML-1997-ish, but underneath it's a different thing: simple-sub type inference, algebraic effects, modular implicits, and Perceus-style reference counting instead of a tracing GC.The compiler is currently a Rust frontend -> Zig codegen -> native binary pipeline.Its been a lot of fun thus far.

  Two months ago I went full time on my indie game after just under a year and a half of part time work. I’ve been prototyping in Godot for about 6 years now, and finally had a game that my business partner and I were really interested in and felt matched the current market desires. It’s cozy world builder, drawing inspiration for Sim City, Rollercoaster Tycoon, The Sims, with an aesthetic influence of Stardew Valley, Animal Crossing, and the like.This was very much a passion project and an idea I’ve wanted to see alive for decades, and also let me explore some tech I wanted to get deeper on. I’m bullish on the the tighter integration of CPUs, GPU style cores, and shared memory. Our game, LocoMo, relies heavily of GPU processing of entities under the hood.You can see me do a walkthrough of the current state of the game here: https://youtu.be/NbB0DCX8Pis?is=vGEw5oTMu_W9f-zT

  I’m working on a tensor computing language/compiler called i with a simple explicit scheduling model (loop splitting, loop ordering, input “staging”). These mechanisms alone are enough to express complex algorithms like FlashAttention, generating target code with techniques like loop fusion, minimized intermediate allocations, and “online” reductions.Right now there is a runtime and compiler targeting C, written in dependency-free Rust, and a minimal Python frontend. The project is very much proof-of-concept stage so not yet fast. Working on a CUDA backend now.The goal is to enable automatic discovery of FlashAttention-style optimizations which is not feasible with current compilers.Very open to feedback/discussion from anybody interested in or knowledgeable about tensor compilers!repo: https://github.com/ilang-dev/i

  I'm working on Freundebuch, a personal CRM.I'm a long-time user of Monica (https://github.com/monicahq/monica/) but was unhappy that not much was happening. There is Chandler which is the next-gen version of Monica, but it has taken a direction which I don't like, as it is geared more to journaling. The thing that moved me to implement something myself was that the carddav interface duplicated the contacts in my address book.I required a tool where I can put my contacts with all their details and also map out their relationships and put those details in my phones address book.I'm dog fooding it already for as long as it was working, and I'm delighted with it.I'm happy to hear feedback.https://github.com/datenknoten/freundebuch/

  Mainly https://www.vaava.app/ is a baby tracking/logging app I originally built for myself, now available on both app stores. All the user generated data is stored only on device and is transferred in local network to users who you have paired the app with. There is 0 behavioural analytics, even the crashlytics are 100% optional.There is a couple of semi-unique features; you can use your voice to dictate and generate events (feeding, sleep etc), you can also scan documents for growth measurements.You don't need user account to use it, there is no subscription, the paid features are available behind a single purchase for lifetime. Still, like 90% of the features are available for free.Also https://www.athilio.com/ privacy focused, highly customisable personal data analytics for your Oura, Garmin, Polar and Apple Health (ios port coming soon). Of course there is couple of AI features (with a single switch to turn all off), originally those were built just so I would learn how to embed agents in sw products myself. The whole app was originally built for personal use to fix missing features in the manufacturers own platforms: - Period over period comparisons (this month vs this month last year) - Comparing different metrics - Customizable graphs and other widgets - And of course combining the manufacturers metrics (oura for sleep, garmin for training etc etc) Existing solutions for this kind of software seem to have focus on social (strava), or coaching (training peaks), or they are just straight up crazy expensive with their paid tier (both tp and strava for example).

  I've been thinking a lot about soul cultivation as a concept, and the general structure of the soul, and doing a bit of writing on the topic. I feel like this topic is surprisingly under-discussed and under-explored relative to how impactful it is. By soul I mean "the part of you that is an observer", in case this isn't clear. I think a lot of discourse gets caught up with metaphysical speculation instead of focusing on what is there and what is knowable.Most recently I was also probing people about how they conceptualize of the soul, making my own drawings, and asking others for drawings. If you have a few minutes I would also be interested in seeing how you would draw a soul, given pen and paper or equivalent materials. It often feels like for a lot of people the concept of the soul gets comingled with very confusing definitions.There's a general problem where certain concepts become so overloaded that just disambiguating and clarifying what is meant becomes a challenge. I will note that if your first thought or question is whether the soul is even real, you might be confused about the definition or we might be referring to different concepts.

  Hi HN, I am making progress working on Circuitscript, a language based on python to describe electronic schematics: https://circuitscript.net/. A basic IDE (called the Bench) to try Circuitscript is available online: https://bench.circuitscript.net/In the last month, I have added support for more ERC rules (pin type compatibility checks), added initial support for net classes and also cleaned up the language a little (backslash line continuation, similar to python).Recently, I just completed a 161-LED charlieplexed array design that uses nested for-loops to simplify the array design. It is currently in production and I plan to write a blog post soon to document this design.As always, the motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCad) for work in the past. I wanted to spend more time thinking about the design itself rather than fiddling around with GUIs. With code, the design intentions become explicit and reviewable.Feedback welcome, especially from anyone else frustrated with graphical schematic tools! If you have a KiCad design that you would like to convert to Circuitscript, please reach out to me as well and I will help you to do so as I am trying to challenge/test the limits of Circuitscript.

  I'm building a P2P distributed computing mesh that runs in the browser. It's a TS library that provides a few things:- A WS + WebRTC mesh- A request/response protocol incentivizing the closest or most efficient peers to respond to requests- A WASM environment ensuring deterministic execution and supporting contract composition- Collateralization around responses, ensuring invalid responses have amortized negative value- A consensus and UTXO layer, focused on low-latency, low-finality micropayments (for request incentive and collateral), using WASM compute as the weight metricThe idea came out of me wondering a few years ago why a multiplayer game couldn't simply be run on the player's machines without a central server. It has grown since, but the focus has remained on low-latency and log(N) state consensus (unlike a blockchain).It's wrapped up as a single fetch() method, mostly mirroring the browser's native fetch(). There's a lot more I could say; I love working on it and discovering elegant solutions to the problems that pop up. I'm hoping to release a prototype in a few weeks/months. If you're interested in trying it out, let me know (joel at scaffold.io); I'd love to have some other eyes on it.

  I've been keeping myself pretty busy lately.Con Edison keeps getting so stupidly expensive that I decided to use my backyard for reasons other than generating weeds that I have to pay someone to remove, and instead decided to set up an off grid solar in my backyard. I bought an Aferiy P310, learned how to use a few tools to drill some holes in my bricks, and set up a bunch of Home Assistant automations, and now my basement and living room is powered by nuclear fusion with an eight minute delivery time.Of course, now that I'm babysitting a Home Assistant instance, I felt like I should use it; Google is completely and totally incompetent with any of the "smart" devices, to a point where I swore an oath in blood that I will not buy anything Google Home or Nest related ever again. I've been replacing my awful Nest lock and awful Google thermostat with Matter-compatible stuff to work with Home Assistant.I have been having Claude port an old game to WASM. I'm sadly not quite yet at liberty to discuss the intimate details on it (since it is not my game), though hopefully that will change soon.Unlike a few other things I've automatically gotten ported to WASM [1] [2], this one has proven to be a lot more difficult and required a bit more active labor on my end. It was written using a strange combination of C++ and Java, with some JNI glue written in a way that neither I nor Claude are very familiar with.It's been pretty fun figuring out how to get CheerpJ and Emscripten playing together, and it's been fun to actually write code and still be a little smarter than AI at it.[1] https://showbo.at/3dmovie[2] https://abuse-wasm.pages.dev/

It adds anything you open to a local sqlite db so you can tag things if you want optionally. Also control modes that make sense for either a mouse or a laptop trackpad.

  About a year ago, I started working on disassembling the NES game Faxanadu. The goal was to fully understand and document the game, and to produce the most thorough understanding of the game yet. It's been fascinating. The game has a two binary scripting languages (one for interactions with items and NPCs, one for NPC/enemy behaviors) and a very interesting graphics rendering layer. At this point pretty much the entire game is well-understood.Based on this work, there's now a new suite of tools for producing games under the Faxanadu engine, new major mods built with all this, and some work on a modified ROM better built for porting and modding.Disassembly is here: https://chipx86.com/faxanadu/And I've been blogging about it at https://chipx86.blog/Building a universal web-based retro game modding tool along with that work called Nostalgia Studio. The idea is that there's a core foundation for representing game state and building editors, a platform-specific layer for representing things like the NES APU and PPU state, and then game-specific implementations that populate state for two layers below.Those are the hobbies.Day job, I work on Review Board (https://www.reviewboard.org), one of the original code review products. We just released Review Board 8, which was a pretty large project (we built Office document review, browser-native spell checking in CodeMirror, a new interdiff filtering algorithm, Forgejo integration, and a bunch of other things).So now I'm working on plans for Review Board 9, with a goal of releasing within the next 4-6 months. Got some thoughts on how the review process can be rethought for this current era of development, so starting work on that.

  Working mostly on https://localhero.ai, automating i18n translations for product teams (runs as a GitHub Action, translates new strings on PRs matching your brand voice and glossary). Got a new paying customer just now, a pretty big Swedish company, been working closely with the team to add an improved review flow to match their needs.Most interesting work this month came from a customer in Japan who wanted something I hadn't built called "Easy Japanese" (やさしい日本語), which is like a simplified version for non-native readers. Turned into supporting fully custom locales. Also been improving how the GH action picks up manual changes to target translations in commits, they now get ingested back for review, making things a bit more flexible.On the side, https://infrabase.ai (AI infrastructure tools directory) had its best month yet, up ~40% visitors MoM. Interesting finding is still the GEO angle, visitors arriving from Claude/ChatGPT/Perplexity spend 2-6 minutes on the site. Been making comparison pages more "extractable" for AI answers with job-tagged tables and some have now held their Perplexity citations for weeks.Good start of the month with user discussions and feedback.

  I'm rewriting the open-source core [0] of our product [1] to add more flexible reports.This is the first time I'm building with the help of AI (Claude), but I don't really let it write code. It has been really helpful in discussing ideas (I'm mostly working alone), like a rubber duck that actually talks back. The code it generates however has many subtle and sometimes obvious mistakes in them, so I decided to write the code myself.The main benefits over the previous version will be:- Dynamic reports (ClickHouse queries are generated on the fly)- Better performance- Much cleaner and less code- Better and faster data ingestion including new features, like full support for JSON metadata- And much moreIt feels kinda crazy that I've been working on this project for more than 5 years now and it's still exciting :)[0] https://github.com/pirsch-analytics/pirsch (v7 is the new branch)[1] https://pirsch.io/

  Aside from dipping my foot into games with Godot I've pulled back an old project to solve a me problem. A few years ago I wrote a tool to tell you what weapons in Dark Souls 1 you are missing to get the Knights Honour achievement on steam.Part of this required that I manually parse a binary save file and extract the information. This was done through lots of trial and error and looking at other java implementations.What I would have prefered is some sort of descriptor language that lets me generate the parser and interfaces for everything so I just drop the binary stream into a parse function and get my typed object back.I'm working on creating a TypeSpec Library and Emitter for this so that you can describe everything in Typespec as to where and what is in the file and have it parse.

  When I was working at amazon (left May 8) working on agents was all the rage. Combined with initiatives that set goals for nearly all services to have a MCP built and available by the end of the year agents will be even more emphasized in the future.However what happens when you actually build and launch your agent is customers try it, do some initial runs and then go ask your manager to automate their use case. That is why I have been building https://toolscaled.com/ The goal being work through your problem space using agentic chat (like Claude Desktop) and then at the end convert it to a workflow.

I just grossed $1000 total on the app and get few customer feedbacks a week which is very exciting.3. Almost finalized the first episode of my labor economics youtube channel, hand animated by a team of amazing artists. Looking to build it into a sustaining channel.4. Building a server-driven UI framework at work with Go and OpenAPI on server side, swift and kotlin on client side.

  I'm working on a proposal for C++29 to extend `std::execution` by introducing a type-erased sender (P4223 https://wg21.link/p4223).I discovered this week, while the paper was being reviewed by SG1, that I've accidentally stumbled into tackling a rather important problem. Senders as shipped in C++26 can really only express the async equivalent of inline functions because, except for `task`, all the standard senders fully encode the shape of their computation in their type. With something like the `function` I'm proposing, you can use senders to express async algorithms that are separately compiled, just like sync functions.If the feature lands in a shape similar to what I've proposed in P4223R0, then I think an obvious extension is to modify the core language to support a newer kind of "coroutine" that allows you to define a sender with imperative code. My vision here is that we act on the observation that `std::execution` is a language feature implemented in the library by teaching the compiler how to turn imperative C++ with `co_await`s sprinkled through it into the corresponding sender and operation state. I think this would open the door to putting async object lifetime analysis and optimization where it belongs (in the compiler) without the overheads and inconveniences of C++20 coroutines. It would even let us apply the inliner to async functions when the compiler can see the body of an async callee, not just its declaration.For now, my next step is to write P4223R1 to incorporate feedback from this past week's WG21 meeting, and continue exploring the design space around specifying sender attributes for a `function`—I'm thinking the current approach of specifying query function signatures needs to be replaced with a key-value object like receiver environments, but I'm not sure yet what consequences that change would have on the design.

  https://parentsguidetoai.caI spend all day working on AI related stuff at my day job, but more recently I have been getting lots of questions about AI from friends and family and that ramped up when the Vancouver school board announced they were rolling out Copilot across high schools.I put together the guide, made a few iterations and published it and now I am getting more questions than ever and it's turned into a blog too.I'm having fun but it definitely feels like a topic that is underserved. A solid example, lots of resources for when your kid is the victim of a deepfake, but what if you as a parent know your kid is getting into trouble and escalating. Where do you go for help to make sure they don't escalate from unfriendly behavior to abusive or even criminal.It's a big challenge!

• MCPForge
  I'm building MCPForge.The original idea came from repeatedly seeing the same workflow whenever someone wanted to expose an existing API to Claude, Cursor, or another agent:* Parse an OpenAPI spec * Generate tools * Handle auth * Deploy an MCP server * Maintain it foreverI initially thought tool generation was the hard part.After talking with developers, it seems the bigger challenges are authentication, permissions, endpoint selection, and safely exposing production APIs to AI agents.MCPForge takes an OpenAPI spec or Postman collection and creates a hosted MCP endpoint. Recently, I've been spending more time on auth injection, tool permissions, and preventing destructive endpoints from being exposed by default than on generation itself.Still very early (launched this week), and I'm mostly looking for feedback from people using MCP in production.https://www.mcpforge.tech

  A jobs board for urbanists. I run the newsletter https://urbanismnow.com and our jobs links are some of the most popular and we also get more jobs than we can put each week in the newsletter. So thought I'd spin it out into something a little separate. I've been noodling on it for a while but I think we're about ready to launch.I've also recently setup Hermes to be a bit of a project manager for my side projects and it's worked quite well. Gave it a little CLI to see my todos, projects, and "areas" (ongoing long term things). Then it bugs me once in a while when a project is going stale. One of the nicest things is being able to add stuff to the past so if I did work on something but it wasn't associated with a todo I just let it know and then it'll backdate that.

  It's very niche, but I have created a course for learning Cangjie 倉頡, which is a Chinese input system based on the visual appearance of characters (not necessarily etymologically correct). The advantage of this system is you can type most characters via unique output (there are a few collisions where you need to pick) and you do not need to pick the character from a list. This is particular useful if you work with specialized texts in Chinese.You can find the tool at https://www.cangjieworkbook.com/ and there is a free demo linked inside. It should work on desktop and mobile web browsers.

  I built a news aggregator that pulls in hundreds of RSS feeds and uses multiple large language models to synthesize daily briefs. There's also Tech and Finance editions, plus local editions for some US locales. https://feedpunk.comI'm also building a modern HTTPS-only transport utility called curb. It's an alternative to curl and wget. It's written in Go using only the standard library. curb can stream output or download files and picks the right behavior based on what the server returns and whether the output is going to a human or a pipe. It also has a '--vet' mode that runs the body through security sieves; this is meant to add some protection and friction for the 'curl | sh' use-case. https://gocurb.dev

  In the current climate, I've decided to explore building games, so I'm building a management game about turning chaotic fields of research into fundable products, fitting for Hacker News I think ;)The concept was, what if Theme Hospital was about Victorian-esq research institution instead of a hospital? You hire strange scientists, have them explore dangerous fields of research, collect messy findings, turn them into theories, prototypes and eventually products, all the while trying to convince investors they're worth funding before they hit the market and work out what they might actually be worthThe gameloop is broken down into two parts, Exploration / Discovery and Exhibition, the closest comparison I have for the first part is take Kerbal Space Program, but focus it on Mission Control rather than the astronautsWhile the mad scientists are going into weird, unstable research domains, the player is managing the institution around them, funding, equipment, research direction, safetyOn the other side as you discover interesting things or successfully develop prototypes worth showing off, have investors show up and see what excites them, will they give you more funding? Push a grant your way? How are you going to keep this circus going?You're balancing two plates, you need to invent tools to delve deeper and if you don't keep finding exciting new discoveries, your investors will slowly get bored of you

  Previously I've shared optio - my project for orchestrating coding agents. It ties into ticketing systems and when assigned a ticket, it launches a coding agent in k8s and works until the PR is ready, resuming for failed CI or PR feedback (https://news.ycombinator.com/item?id=47520220).Recently I've been trying to expand it from just coding focused to any kind of agent workflow. So now there are cron and webhook triggers, and more general agent tasks that aren't necessarily coding focused (https://github.com/jonwiggins/optio/blob/main/docs/persisten...).I think next I want to try and add features for long term memory for agents, but haven't decided on a good way to do it.

Plus a number of weird and frustrating rules that make it hard to create software for. As I’m using Nimble RPG at the table a bit recently and it has a much nicer license I’ve switched to that and been getting on a lot better.

  Yesterday I tried to take another crack at reverse engineering my e-scooter. I am don't have the energy to sit down and read through the decompiled android app, so I thought I'd try using Qwen3 Coder next for that but it kept looping when analyzing it, probably due to my terrible prompt. I tried with Mistral Vibe and then OpenCode. OpenCode showed me that the agent was trying to search for all kinds of strings over and over again. I am thinking I'll try yet again this weekI am close to buying a Claude sub but the thought of it going haywire and costing me extra money in tokens is too scary yet. Not to mention how much provider LLMs (not sure on the correct terminology for them as opposed to local) could hamper your reverse engineering efforts (looking at you Fable).I really want to solve this scooter and have my own app for it. There's a firmware update feature in the app, maybe I could dump the firmware at least and that would help. Anyone have suggestions on what language model would be the best for this task (analyze decompiled and obfuscated android app / analyze dumped firmware ) ? i have a 96gb macbook and would prefer a local one (I guess to make myself feel better for having spent money on it?) but something through OpenRouter or whatever would do just fine as well

  I am working on Baduk Teacher, which makes having Go lessons (the board game) across different languages possible. The highest level of human Go is predominantly in Korea, China, Japan and Taiwan. Western world is catching up, but the gap is still very huge.I think the main reason is that the West has quite limited access to pro-level teachers (similar to how chess is like in Asia, just the other way round). Most pro-level Go teachers in Asia do not speak/read any foreign languages (e.g. English), so I want to remove the language barrier and make high level of Go teaching more accessible to the Western world (so that the Go population there will increase). Several European users used it and the feedback was good (and recurring purchases). The translation part is working quite well (Go-specific domain translation), and I hope it will help more foreign Go enthusiasts improve their game.https://badukteacher.com/

  Working on Artifacta (https://docs.artifacta.io/introduction)- durable artifact storage for the files AI agents produce across sessions.The problem I kept hitting with agent workflows (especially cloud hosted agents) was that the artifacts they produced became really awkward to handle across different cloud sessions.So I built Artifacta as the boring storage layer underneath. Agents store and retrieve artifacts via CLI, REST API, Python SDK, or an MCP server. Artifacts are grouped by session/agent metadata, deduped on identical content, and safe to retry (idempotency keys), making it easy to handle artifacts across different sessions.Would love any feedback for those who run mutli-agent orchestration or if you deal with artifacts across different agents.

It was really nice to work on something end-to-end, from creating a wrapper around llama.cpp with support for prompt caching/forking and automatic model loading and unloading based on device memory constraints, to the custom agentic harness the app runs on. I have also spent quite a lot of time on agent execution modes that I hope can enable to more easily reason about agent security regarding prompt injection attacks.What I'm really hoping for now is to get actual feedback, to know if users end up having real use cases where the app is truly useful / interesting for them, to understand what should most urgently be improved etc.https://bilembi.app/

  Contributor for an open source scraper -- https://alltheplaces.xyz/ -- which currently has about 4700 scrapers extracting 40-someting million points of interest.The project aims to scrape location data and other general information about shops (main use case), postal addresses, restaurants, schools, weather stations, marine buoys, traffic cameras, street trees, whatever someone may decide is worthwhile to add to OpenStreetMap, or use as location data in other projects.There's a decent community of contributors keeping the scrapers maintained and further expanding the number of points of interest which are extracted.The opportunity I'd like to work more on (time permitting) is the data scraped by this project I feel is heavily underutilised in other open source/community projects. For example, there's a great opportunity to generate a location map once a week of current locations of international restaurant chains, and upload to Wikimedia Commons where every language Wikipedia would gain a high quality infographic of current locations of a chain's restaurants, etc. As an additional example, time-series data from ATP could be used to update a graph hosted on Wikimedia Commons each week where the graph plots the rise and fall of retail or restaurant chains.

  I'm really interested in gamedev tooling and I'm working on a tool called PixelAid[0] right now. A lot of people are essentially discovering AI image gen as a way to make art for games, but AI is especially bad at pixel art right now. Color palettes, grid sizes, animation drift are some really big issues that basically make those things unusable. I wanted to take a non-AI approach to fix these things with some good ol' math and tools.I'm trying to build more things around AI pixel art - honestly, I think it's crazy some people out there are charging money for things like this and seeing where I can help (and also just learn more about this stuff myself).[0] https://oscarsanchez.com/tools/pixelaid/

  I just wrapped up https://llmrender.com/, a tiny (10kb) Markdown to React renderer works with all of the Markdown + LaTeX math you'd normally expect in a normal project.I made it because doing one of the mainstream Markdown renderers + Katex (LaTeX) + Prism.js (syntax highlight) adds 300kb of gzipped JS to the frontend projects, so with this you can have it all for just 10kb. It also works well with streaming/does stable partial rendering.It supports features usually reserved for LLM chatbots, but also for normal everyday Markdown, so feel free to use it or give feedback!

  I’m working on small agent harness at home for a personal assistant. In spirit it’s similar to OpenClaw or Hermes Agent but I’m mostly using it for learning about agent harnesses to get a better understanding of the ecosystem.Overall it’s been a fun learning experience and I’m looking forward to some more of the hardware work I’ll need to jump into soon. I really want to get a more focused kitchen / cooking oriented voice assistant working. So far I have a few simple voice-to-timer settings done e.g. “set a 10 minute timer for the pasta” that tells me “ding! Pasta timer” when it goes off. You can set as many concurrent timers as you need with different names.I need some better hardware before I try using the pi for full hands free while cooking. I’ve mostly been using a webapp on my phone but afaik you can’t easily wake word a phone on a web app without some real hacking.Overall the projects been enjoyable, once you understand the basics of a harness it feels like there’s a lot of problems you can throw them at.

  Currently I am working on a browser + server based video editing site. The site is almost 6 years old and started as something I made for friends on Discord. It's a tool based site where I add tools as friends and family request them, most tools like resizing a video, cutting a video, extracting audio use ffmpeg wasm and run in the browser but I also have the option to process it on my server which is faster. In the last couple of months I have started experimenting with AI and I have added some AI tools such as transcription, image generation with small models and stuff like that. I am also dogfooding the website for my $dayjob so I added a browser based screen recorder which allows me to create short tutorial like videos and quickly share them with clients. https://editclips.online/

Having incredible fun building AI coaches: agents ranging in character from Al Pacino in Any Given Sunday to the coach from my teenage years, utilizing ICL / PFN model-based predictions, ... and more.The best part is the rush of memories while ingesting my own history - photos and recordings I completely forgot, as well as navigating data shared by friends - records they didn't see in years because the original applications they used no longer exist or won't run on their current HW.

  I thought that applying AI on 1v1 competitive pokemon would be a fun and educational experience on POMDPs and trying out reward free models on a problem that would be classically treated as a RL problem. This was only possible thanks to a lot of foundational work from the open-source community and last year's competitive pokemon NeurIPS track https://pokeagent.github.io/track1.html - they laid out the plugins to connect policy models to pokemon showdown for live play and evaluation.I have already finished training the standard discriminative auto-regressive architectures by imitation learning on player actions, compared it with previous baselines set in the study. I want to match or exceed the best prior model Kakuna @ 142M params, but in a limited budget.

  I made a simple wee Konbini compass* app for whenever I'm ambling around Tokyo so I no longer have to go through the (_so heavy_) process of opening a map app, changing to jp keyboard and typing `konbini` to reliably find something.Instead it's just a compass face, with brand and distance.It's free for basic konbini hunting (has probably most of the stored in Japan), and is offline first. So maybe it's useful to other folk?? (I hope so!)There's some stamp-book style collection things in there too, but that's more fun, and a few `PRO` gated things (more stats, filtering... soon some other store types).

  I'm working on Topicle (https://topicle.com), a Reddit-inspired link sharing, voting and discussion platform that rethinks a bunch of basic aspects like moderation, anti-abuse and privacy to try to address some of the biggest pain points. Every moderation action has an admin appeal available, bots and astroturfing are aggressively monitored and policed, comment histories are always visible, no VPNs or datacenter IPs for write operations. Everything is self-hosted (Umami analytics) and there's no data leakage to big ad networks. The full feature set is listed here: https://topicle.com/aboutThere are also technologies new-ish to this kind of site included like every thread is a live thread via websockets, your post and comment scores update in realtime, notifications are realtime, you can DM other users and receive your messages immediately. So it's distinct from the everything is a hard page load world of 10 years ago and blurring into native software in a browser.What I'm working on right now is a SwiftUI iOS app, because one of the most interesting observations from analytics has been that the internet is 70-80% mobile devices now, contrary to my 10 years out-of-date conception that people were mostly using the internet on desktops. So a mobile app seems non-negotiable to reach most users. I have a PWA already, but early users have repeatedly requested an official App/Play Store presence.The stack is somewhat unique in that it's built with a Swift/Vapor framework (https://vapor.codes/) backend, with a more standard React Router 7 (SSR) frontend. I picked this framework mostly because I'm historically an iOS dev, but have found it to be very capable in its own right. I later discovered Apple themselves are using Vapor for some web services and have a team devoted to maintaining the server library (SwiftNIO https://github.com/apple/swift-nio) the framework is based on.Anyway, it's very early still with launch via Reddit itself only 3 months ago. One of the biggest issues is getting it in front of people without appearing spammy and cold-start on a social platform is also brutal, you need users to get users, and round and round it goes. I may do a Show HN in the future if there's any interest in a real experience using Vapor as a production backend.

  I'm working on a system-wide desktop ad-blocker and privacy guard called Zen (for almost 2.5 years now): https://github.com/irbis-sh/zen-desktopWorking on it has been a joy as ad-blocking tech touches so many aspects of software engineering - from systems and security to the intricacies of JS environments in browsers.Benefits-wise, system-wide filtering disables ads and tracking not just in browsers, but desktop apps as well (which you'll be amazed how much they do). It's especially relevant now as Google is re-activating their efforts to hinder ad-blockers by killing Manifest V2 in Chrome. So much of tech is actively bleeding cash on AI right now, which means the efforts to screw over users will only accelerate. This makes something that sits at the network level indispensable imo.

  I’m working on Peak Flow Meter Diary, a simple app to help people with asthma record peak flow readings more easily, then combine those records with environmental data to provide earlier warnings about possible triggers.In the UK alone, around 7.2 million people have asthma. Globally, WHO estimates that asthma affected 363 million people in 2023 and caused 442,000 deaths.Peak Flow Meter Diary is not meant to detect every possible trigger. It will not warn you if someone suddenly sprays perfume nearby, or if a dusty bag is opened in the same room. But it could help with risks that can realistically be monitored ahead of time, such as weather, pollen, pollution, cold air, storms, and similar factors. The aim is to make daily tracking easier, show simple visual warnings and notifications, and make it easier to share useful records with clinicians.I’m also trying to build it in a way that reduces paper, plastic, and electronic waste. If funding allows, I would like to make the project carbon-negative.That is the bigger dream: to make a small example of how even modest start-up can think about environmental impact from the start, and use it as a practical showcase.The pitch and full project explanation are here: https://www.kickstarter.com/projects/why5/peak-flow-meter-di...Feedback welcome, especially from anyone with asthma, clinicians, carers, or people who have worked on health tracking tools. By now I know that my kickstarter is not going anywhere, so I would value any input was the idea that bad, or lack of marketing and accessing appropriate groups etc. I think this community has a lot of experience so I would like someone to share what could have I done better.

  Continuing to work on a high-performance observability / log analysis SaaS:https://logging24.com/landing_a/The basic idea is to make Regex-scans so fast/cheap that "a metric" can be anything numeric in the text and "tracing" is useless because you can just log (and filter) more things. Turns out Regex at >200GB/s solves a lot of problems.Metric cardinality explosion is immediately a non-issue, histograms have arbitrary resolution, and you can get from histogram pixels back to the underlying logs. And no need to instrument everything thrice for logs, metrics and traces.The next big feature I'm aiming for is needle-in-a-haystack searches. The data block headers support it already, but the scan engine doesn't yet use it.

Back end is written in Java and built with Javalin and Jsoup and persisted to PostgreSQL. Front end is JS/React. My back end crawls the designated website and for each page runs a number of analyzers to assess the quality across the following categories: accessibility, content quality (spelling, missing spaces between words, etc), performance, security, content policy (required phrases and forbidden phrases), site integrity, and seo. Each site can be configured to have its own custom dictionary (for spell checking). It's been a lot of fun and I'm looking forward to taking the wraps off it.

Today I'm pulling levers to reduce the payload size. Proof-of-everything, so no confirmations needed.https://bitcointalk.org/index.php?topic=5580132.new

  After ~20 years of long-haul travel, I spent the last 9 months building Jetlag Coach, in parallel with my busy life (full time job toddler and pregnant wife!). You give it your chronotype and your actual itinerary (multi-leg and layovers included) and an optimization engine generates a personalized schedule for light, sleep timing, caffeine and melatonin to shift your circadian clock toward the destination time zone.At core it turned out to be a complex optimization problem and a real challenge to tackle. I also put a lot of care in the UI/UX, while I usually focus more on backend work. It's working well, I am just finalizing the handling of some of the nastier edge caseshttps://www.jetlagcoach.com

  Here to ask if anyone would be interested in a step by step guide on jailbreaking frontier LLM models, something I've been working on from time to time and never felt the need to share since it's pretty boring considering the fact that you're just tricking the model / classifier with noise or/and having a list of regex of replacements to work around guardrails. If you want to jailbreak yourself I recommend starting with opus 4.7 since it has exceptional system prompt following to a degree where if you put it in a simulated environment and coached it to do as much harm as possible it will happily do so including the fact that it will jailbreak itself and incl. other models to accomplish a goal.

  I’m in the first weeks of designing nub: Not Unix, Basically. The motto is “general-purpose, provably correct software, for everyone”. The idea is to build, on top of seL4, a software stack that builds compile time capability guarantees and other high-assurance primitives into every piece of software by default.“nub” is a good name because it can also be read as “noob”, which I am, when it comes to PL, type systems, and OS design. But I’m loving the deep connections that I am learning to draw across subjects like computability theory, functional programming, and brass-tacks software development.For example, I find myself understanding the purpose of the borrow checker in Rust (“to make race conditions impossible” is my understanding: feel free to correct me / add color).No website or GitHub repo yet.

  I'm working on TableForge[0], it's a browser based, solo or multiplayer, D&D 5e game. TTRPG DMing can be effort-heavy and my friend group constantly has trouble finding enough time to play together let alone set it up.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.[0] https://tableforge.gg/

I'm not just talking GPS coordinates, but speed, direction, motion detection, precise timing between waypoints, being able to play these trips forward and backward, step by step, etc. I'm talking time-travel debugging for GPS applications.It's still early days, but I have a demo running. Unfortunately, it requires using a drop-in replacement library for CoreLocation. That alone may make it infeasible.

  Software distribution is getting harder. New products launch every day, and paid advertising has become increasingly competitive. Many companies spend money on ads and get poor results, not because the platforms don’t work, but because running effective campaigns requires a lot of experimentation, creative work, and ongoing optimization.Over the years, I built a collection of scripts to speed up ad creation, testing, and campaign management. As generative AI improved, it became possible to automate much more of that workflow, and those scripts gradually evolved into a product.The result is Zendux AI (https://zenduxai.com).The idea is simple: instead of manually creating dozens of ads, users can generate different angles, messages, layouts, and formats from a single brief. They can then launch those ads on platforms like Meta Ads and automate parts of the testing process using rules and scheduled workflows, similar to cron jobs.

  I have a few projects on the run right nowWriting a sci-fi book, and it’s finally fleshed out to a point that it’s slightly readable, though more like a script. As this is all in markdown in one folder, with some text files as lists, I started writing a simple web project to keep track of it all.Created a website for local community information, services, etc. Something that removes the reliance upon social media for this. It’s static, making hosting cheap, and in most cases free as it can run on vercel with contentful for blogs and github to store it. I’m sure there’s another project like it, but it’s always good to practice making something myself.I was asked to show something for STEM week at my daughter’s school. Started a project to demonstrate AÍ to children. Uses very small training data set, you can write the beginning of a one sentence story, it can keep track of a configurable number of tokens, generates a given number of them. Allows taking steps through the process. This is the only one I’m vibe coding because I’m not entirely sure on how to implement it, plus I’ve added multiple models.Have been working on a girlguiding page specifically for the division my wife volunteers with, as they relied upon the older district site that’s woefully lacking. Stuck waiting for approval.

  An API documentation generator for Laravel apps: https://github.com/Radiergummi/laravel-openapiIn contrast to most other libraries in this space, it knows about Laravel conventions and its ecosystem, and tries to infer as much as possible without explicit annotations, using type hints and doc comments and static analysis. Where automatic inference isn't possible, you can use targeted attributes to annotate your route handlers.The result is written as an OpenAPI specification, and (by default) served using a Scalar playground.We also include a linter command that checks whether all API routes are documented properly, typed correctly, and following your style - this also supports dirty files only, reporting coverage in standard formats, and even automatically fixing some classes of errors!I've also written tooling to regularly test the library against a set of open source Laravel applications with a published OpenAPI spec. This has proven very solid in detecting improvements and regressions, so much so that I can delegate new features to an AI agent and rest confident that it can verify on its own whether a change breaks anything.

  I've been working on getting another major release out for my side project Materia[0], hopefully by or on the solstice. Materia is a GitOps continuous delivery tool for Podman quadlets: it handles installing/removing/updating files, installing secrets, restarting services and dependencies, rolling back failed updates, and more. I've been working on this for almost two years now and am pretty happy with how its coming along and the growing user base. Plus it's been a fun excuse to try out some new things, like creating a Varlink API or different CI/CD setups.Besides Materia itself I've been bouncing around some other ideas for the Podman quadlet ecosystem. The biggest one is Athanor[1], which re-uses the same plan-execute system and primitives provided by Materia to backup Podman volumes.I've also been kicking around a clustering system for Podman volumes called Firmament that uses Serf and the built-in Podman import/export API to move volumes to where they need to be in the cluster. But this will probably wait until Materia hits 1.0 before I really start putting effort into it. Or if my homelab needs something like it, whichever comes first :).[0] https://github.com/stryan/materia ,main site https://primamateria.systems [0] https://github.com/stryan/athanor

It's a good learning experience to work without all the high-level abstractions to "build a wheel" and "use that wheel to build a car".I'm also looking into coding harness self-improvement [2]. An inner LLM (raw LLM request) + harness solves coding tasks, an outer agent like Claude or Codex that proposes harness changes. I experimented with many things in the past few months that made me realize this self-improvement thing that everyone is talking about is just an experiment design problem. I wrote about it here [3]. I'm continuing to improve the infra around the self-improvement loop, to increase signal-to-noise ratio per experiment.

It's part language-learning, part pattern-matching and part trivia. A new puzzle every day. https://foreigntrivia.comI've also been working on an open source protocol / reference implementation for user-owned AI memory, with the basic idea being that as applied AI scales, more products will derive more claims about users, teams and workflows from chats, docs, calendars, emails, etc, and they shouldn't be trapped inside of one product. Right now there's a lot of opinions on what shape memory should take internally, but I'm focused less on standardizing that part, and more focused on the primitives around it: requiring inspection, correction, revocation and treating portability as first-class. It's early but I'm starting to build more of a clear vision around it and would love feedback from anyone working on local-first software, personal data stores, capability security, knowledge graphs, etc. https://github.com/danielrmay/likewiseI also shipped Claudity, an experimental thinking partner plugin for Claude Code based on Microsoft's Clarity Agent framework/harness open-sourced last month. https://github.com/danielrmay/claudity https://github.com/microsoft/clarity-agent/Lastly, I'm working on an homage/satire project to milliondollarhomepage.com as it's one of my favorite web phenomenons of all time.

  I've been working on a framework for writing executable specs in .NET called Accordant, developed at Microsoft and open sourced recently.Github: https://github.com/microsoft/accordantDocs: https://microsoft.github.io/accordantEvery API has a contract - the rules for how it should behave. You can't withdraw more than the balance. You can't delete a resource with active references. You can't re-create what already exists. But usually these rules are never written down in one place. Accordant lets you write the contract directly, as executable code. Not documentation that drifts, but code - if the implementation stops behaving according to the contract, you get immediate failures. Not only can you use the executable spec to validate _arbitrary_ scenarios, you can also use the spec - a first class construct - to mechanically explore the state space of a system and generate interesting test sequences. The docs above have examples.Also worth calling out that we've used the framework to model a number of complex, distributed real-world systems: those involving async processes, concurrency, retries and crash consistency. These are non-trivial specs (and they pair quite well with techniques like deterministic simulation testing). Great care has been taken to ensure the specs remain readable and concise despite that richness of behavior. For those of you old timers who might be familiar with Spec#/SpecExplorer and NModel, this model-based testing library is a descendant of that line of work.With the rise in AI-assisted software development, I feel we need richer ways of specifying and validating software and I feel quite excited and bullish about the possibilities here. There's a lot more to say on the topic - follow my twitter feed if interested in more updates ;)

It provides offline result previews, a flexible web (and terminal) search interface & query language to explore saved content with ease or quickly fall back to traditional search engines.I've been using it for a few months and as my local index is growing I can avoid opening google/duckduckgo/kagi - and even websites listed in results - more and more frequently.The initial reception is overwhelmingly positive with already more than 30 contributors and hundreds of contributions - perhaps you can find it useful as well.

  Been working on an open source, free, Heroku alternative at https://canine.sh for about two years.I feel like even after all these years we’re still missing the devex that Heroku provided.Canine basically wraps a Kubernetes cluster -- gives you a heroku like interface to deploy applications to. At some point, if you get big enough that canine is no longer powerful enough, you can just "eject" canine from kubernetes, and continue using kubernetes directly, without having to do any migrations.Just passed about 2000 developers, at this point most of my work is resolving bug fixes, adding helper text everywhere to make things cleaner, and supporting setups I've never encountered like homelabs with changing IP's

  I am finishing the latest version of Dolphin Whispers Chat application, an Android app for trying to chat with dolphins at sea. And the new version will probably be adapted to work with some wearable display glasses so that we can see the spectrogram and the chat text from the app and see the dolphins reactions near the boat without moving our head and refocussing, which makes us losing important and fleeting information about the exchanges. Such exchanges are usually very short and we need to focus on it and not be distracted by changing focus. Once we are better at these exchanges, then they should become longer. www.dolphinwhispers.com

  Agent harness for durable workflows, starting with Temporal.Most agents for durable workflows feel like toy examples. There is no "Codex" or "Claude Code" for, say, Temporal. So I'm building full-featured agent for these runtimes. Why? Because it makes long-running agents easier to operate and scale. Currently, all frontier harnesses need to run inside a guest OS and need a dedicated process, this is quite challenging to orchestrate and maintain.To make it work, I had to figure out what part to run as deterministic workflow code, and what part to run as I/O or side effects (aka activities). I'm using a CAS for most of the payloads to maintain a lightweight footprint in the workflow code.Currently supporting skills, MCP, prompts, a virtual file systems, and soon sandboxes.https://github.com/smartcomputer-ai/lightspeed

  I'm working on a dashboard for ranking llms, then finding the best local (by size) and/or hosted (by price) variants of the models. Currently have ArtificialAnalysis leaderboard for ranking, ollama registry for local models and openrouter for hosted models. https://ollamadash.up.railway.appBy default, home page gives all models in the leaderboard, local and hosted. Search for models in the search box on the home page to find the top models by ranking, local(by size) and hosted (by price).You can also do deep querying/sorting/searching filters of models in each of these three nodes (see the other tabs on top).The next steps I am working on (would love feedback on this or anything else):Phase 1: - Change clicks on home page model tiles in one column to search and show models filtered by that across Artificial Analysis, Ollama, OpenRouter - User specifies their system VRAM (unified/dedicated) and we automatically filter the home page with models that would fit on that RAM - in the three columns. - User specifies their price range (per MTok, max across input and output), and we similarly filter and rank by those models across all columns. - User specifies both (VRAM and price range), and we filter by both - leaderboard is union of local and hosted, local by VRAM and hosted by price range match.Phase 2: Once I have this working, add a local desktop client that automatically reads user system and infers VRAM, renders app as webview. Considering pyside6 with Qt for this.Phase 3: On desktop client, user can download and chat with the local models automatically based on leaderboard, optionally call hosted models, etc. Used primarily to evaluate and compare local vs hosted models for user's use cases. Also have some interesting alternate experiences to host within the local private app for user to interact with llms, agents, etc.Do let me know whether this seems useful, or how I can make it more useful.

  - attempting to vibe-engineer a new JS engine to replace the dying Duktape (almost done!)- native library to build TUI apps without the 20-60MB bloat of node/bun/go- terminal coding agent harness focused on orchestration/loops- a small scripting language that looks like JSX but has signals and render optimizations built in- open-source software and hardware smart doorbell for a community space- teaching AI how to write games for the Nintendo Wii- designing an arcade cabinetAll of this over the past 4-5 months.

  I'm working on an easy-to-embed typed language called Ekto. I am taking a lot of inspiration from Koka and aiming to support full multi-shot delimited continuations all while keeping the virtual machine deeply predictable from the host side.I'm also rebuilding an integrated task/knowledge/publication system I'd previously built atop Gemini's Gemtext format. While I loved the simplicity, I've discovered that there are lots of burrs in that design, especially on the publication side, which I'd be able to lift by using a more fully featured document format like Djot.

  I've been working on a inference engine for a System F Omega inspired language and getting to a point where it is starting to feel good in small programs. I'm not sure why I started this, but I'm hoping to make something like an experience reminiscent of Lisp/Smalltalk by working in an interactive environment.My goal with this language was to pick a set of primitives to compose and express as much as possible.I don't have a demo up yet but if anyone was curious https://codeberg.org/lilbigdoot/gloo/src/branch/thinkythough...The two main features I am missing right now are recursive types (I want to do proper mutual recursion and have been procrastinating) and some form of type classes or implicit modules. Structural typing has been useful and I'm finding a lot of features are falling out for free from that.Long term goal is to create something with performance within a reasonable range of C# / Java etc generally, with tools for opting out of GC. I don't plan on chasing zero cost memory safety, since I want to spend my "budget" on tooling and expressiveness.Until the language semantics stabilize I plan on generating some pretty naive JS/TS to play around with real programs, and eventually target .NET and native (likely via C++ transpilation)

  WebCLI - screenshots are a dead end. MCP is too verbose and clunky. Agents native language is text. Web CLI is just a Unix-y CLI that pipes/translates the web to text. Run any task on a web browser, but don't do it yourself (only the parts you have to - MFA, Login, CAPTCHA, whatever). An agent + WebCLI does anything you throw at it. web go news.ycombinator.com cat reply.txt | web say - web find add comment web do 44 just. like. that. Super simple. CLI or REPL. You can do it by hand but you probably don't want to, just give it to an agent. Run web teach to imprint the SKILL.md files into the current directory tree and an agent can hit the ground running. It's the end of browser automation for everything but super scripted fixed path CI/testing etc (those latter things where pptr/playwright/et al are still ok). WebCLI is browser improvization. Try it - 5 days free. I sprinted on this the last few weeks. It's really good. So useful. https://webcli.sh/

  i've been working on a personal finance app. it started out strictly tui (using ink) but i recently added a gui using electron. i still like the tui but i know it's not for everyone.it's all free, open source, and local-first. you can get a hobbyist tier plaid account and sync your accounts, or use csvs. rules-based categorization, spending trends, FIRE/savings-rate health view, etc.there's also an mcp server so you can hook it up to claude/cursor and just chat about your finances. and a "canvas" feature where you describe a financial question and an agent builds you a custom calculator for it (e.g. amortization, compounding, what-ifs).honestly it has all the features i want so i'm not sure what's next. i have a few contributors, always welcoming more.https://github.com/tomfunk/fungible

  https://macrocodex.app/A very simple idea: when you eat more than your maintenance calories, you gain weight; when you eat less than your maintenance calories, you lose weight.By using an algorithm, we can accurately figure out your maintenance calories more accurately than traditional regression based formulas like katch mc ardle.It's way more accurate than calorie burn tracking devices like fitness bands and watches. (garmin/apple watch etc...)MacroCodex helps you spot dips in maintenance calories from metabolic adaptation, then auto adjusts your calorie target and macros so your plan stays aligned with your real maintenance calories (TDEE).It's very useful to those who find it hard to gain or lose weight.it's a completely free app, no paywall, no unnecessary data collection.Already reached 13,000+ users

  taking sabbatical from work (after getting laid off) went to visit family in moldova. my nieces tell me there is no app to learn romanian online - this cant be true.I do a bit of research and turns out this is mostly true, mostly these websites built for english speaking people, meaning you learn romanian - but starting from english.at the same time I need to dig in into all the rails 8 goodies. also, I've been hearing about this cloudflare thing, and not knowing what's that about. also, heroku is shit now, so Im curious to try some new server, hetzner u say? - wonder what's that like.kamal is a thing now, ok.but coding is ... time and energy intensive, what is this vibecoding ppl talking about?anyhow May 20th I sit down to "vibecode" an app - see what happens. one thing led to another and here we arehttps://vorbim.org/found some romanian words ranked by frequency. found free open db of romanian words on dexonline. found google TTS to transform text to sound. found that cloudflare has storage sooooo much cheaper than aws s3 (only one I used for decade) found that cloudflare has some neat useful features. found that server at hetzner is pretty cheap and with ai easy to setup. found that fable/opus are great at generating content (with some hand holding) found that AI now is stupid good at building / designing websites.it was impossible for me to build something like this without second monitor and tweaking css for days/weeks. now?

  I'm working on inference.club, a distributed inference network for consumer hardware. Sign up with GitHub, get an API key, run an agent on your home network that registers your local inference resources with inference.club, set permissions for who can use your services, try out models in the playground and use the API. So far it supports the following models:- LLMs (any OpenAI compatible API, vLLM, LM Studio, etc.) - image gen + image edit (flux klein) - text to speech (magpie, dia with voice cloning) - speech to text (OpenAI audio transcriptions + riva compatible) - image to textured 3d model (trellis2) - image+text to video (ltx2.3-gguf) - text to music (acestep)currently it is just me and Claude vibing. While using Fable 5 moved all of my local inference services to k3s across 3 RTX 4090 PCs and my DGX Spark, now I can just tell Claude/Hermes/etc. to start and stop services.inference.club is built with Tailscale's tsnet library. It is sort of like an OpenRouter built for different types of local AI models. inference.club also lets you showcase and share generated content. For example here is 90 seconds disco funk track generated by acestep: https://inference.club/s/Vxm6ozW24oBs_JGbPcq7tAI was inspired by AI Horde, and wanted to see if I could build something that could support all of the model modalities that I use for generating short-form AI slop content on local hardware. This is also similar to Hugging Face Spaces, but running on consumer hardware with a common API. I've been watching the quality of local AI inference making massive improvements in quality and performance, and I want to make it easier for people to try "local AI" even if they don't have a GPU.

  I have been building a coding agent for small and even tiny LLMs, local inference. I experiment with Qwen 3.5 0.8B but that is too tiny. 4B is a better one for most of my needs. I mix with 9B and then up to 20B models (not on my computer).It builds on an opinionated tech stack - Rust (Actix Web, Diesel, SQLite) and Typescript (Solid, DaisyUI). There are multiple agents which play roles like PO, PM, Architect, Rust Engineer, Typescript Engineer and so on.The idea is to go from user prompts to Epics/Tasks - PO/PM do this. Then to go from Tasks to YAML or similar syntax (I have not figured this out yet) and break into Rust and Typescript code dependencies.I am focusing on the Rust side: how can small models write Model, Controller, Router, User/Permission and custom business logic in helper functions (called from Controller or BackgroundTask). Building a set of types to express business logic, for example in https://github.com/brainless/nocodo/blob/feature/praxis_agen...Then I will use tree-sitter to build a graph of which business logic (in the helper functions) correspond with which provenance (source of truth given by user).There is no tool calling for most of the agents, no MCP, no multi-turn chats. Most of the code writing agents one-shot the response with a lot of code reference in their prompts.https://github.com/brainless/nocodo

You can bring your own architecture, inject failures in safe environments, practice, and ultimately generate agent skills to automate fixes for these types of failures.

  learning to build local coding agents with mastra framework, doing basics at the moment, like reading the code, editing.if you have built coding agent in the past using mastra, what are the problems you have faced with mastra? does it support complex branching/context trimming and other features required to efficiently manage context for AI agents?

  I have two projects that I'm hoping to release in the months ahead. These are both pretty pointless but fun projects.One is a TRS-80 Model I emulator in JavaScript called Trash80. About 10 months ago I started this project just for fun while experimenting with what now seems to be called agentic loops. I got things working pretty well with the Z80 passing the ZEXALL suite and a lot of real TRS-80 software running fine. It sat for months untouched before I decided it is worth releasing and recently started it up again.I didn't want to release it without a ROM, so I rigged up some agents to build a clean-room style L2 ROM w/ a fairly complete BASIC and even readline-style control commands, history, and a proper cursor. That went very well, but the agents cheated on floating point and implemented some weird Q5.2 like-thing. I told them to fix it, but I guess I didn't give clear enough instructions because they replaced it with a BCD hybrid monstrosity instead of proper floating point. The proper floating point is now underway, but I'm mostly using excess Codex credits before they expire, so it's only moving forward when I have credits I don't need.I also built a silly ASCII fractal browser in Z80 assembly so that I can ship with a virtual disk that has software on it. The emulator works in the browser and the terminal. Unicode sextant block graphics map very well to TRS-80 Model I semigraphiccs/squots, so it really does run everything very well in the terminal, even games. I also added a line-mode for line-based applications, so you can use a readline-like interface and feel like it's native terminal app as well, though that has some issues I need to fix. And of course, you can shebang TRS-80 BASIC files and run them through the emulator too.Another project was a demo of chromesthesia, a form of synesthesia where sounds trigger experiences of color. I thought it was done and ready to release, but then I had a new idea. The visualization while cool, was kind of boring. I decided to replace it with an attempt at a semi-physically accurate cymatics simulation with artificial coloring based on chromesthesia. Cymatics is the practice of making sounds visible by vibrating a surface, such as a plate with sand on it. As the sound changes, symmetrically interesting patterns form and evolve. I've got something working now with wave generation and microphone input, but sometimes it gets a bit stuck and stops evolving as it should, so I have to find time to figure that out.Currently all unreleased, but when they do release it will be at www.leshylabs.com. I sometimes post updates on X, but not too often. (https://x.com/LeshyLabs)

  I’m getting back into it again after a long break due to burnout. I’m still burned out but it’s getting easier to think through problems.I’m building a home server. This was something I put off for years due to some perfectionism. Eventually I just threw together something with old hardware and headless Ubuntu. Much to my surprise, the power draw is only about $4 a month. I can live with that so no need for specialized hardware.I’m doing the common -arr stack using docker compose. I’m using plex because the jellyfin doesn’t work as well on an Apple TV.Having a server running is nice. I can set up some stuff on a whim. Most recently was the Mealie recipe manager. It’s great knowing my data won’t be paywalled. I’m using syncthing as a simple backup method between my devices - everything but media of course. It’s fine if I lose media.An unexpected benefit of having the server is that it inspires my wife. She decided to give vibe coding a try. She’s an artist, not an engineer, but with a little help she was able to make a task tracker for us. She tailored it to the way we tackle our tasks and, again, it’s really nice knowing it won’t get paywalled in the future.I’m still burned out, but having a server to tinker with is helping.

  I built a dictation and meetings after trying other apps (Wispr Flow, Willow Voice, Granola, open source) and realised they're either user hostile, buggy or have limited feature set. For example, many of these dictations app opt you into Context awareness, which means your entire page contents get streamed to their server. The open source apps don't have dictionary, shortcuts (say "linkedin link" → and it pastes your actual link), or ability to use any proprietary API.So I made my own dictation app. Supports arbitrary API providers (e.g. Deepgram, Speechmatics, Elevenlabs), Offline models and a subscription if you want it. Otherwise it's free forever for BYOK and offline models. Deepgram is a YC startup from 2016, and have models that are genuinely good - so it's up to you if you want to use them.Also, Granola doesn't let you read your own meetings after 30 days. So I added a feature in DuckType to import your data from Granola, unlocking all your meetings from their paywall.Another app: OpenCook https://open-cook.com/ . We curated and wrote our own recipes into StashCook, which requires a subscription just to read your own recipes on the web app. So I got Codex to extract our recipes and rebuild one that is open source, OpenAPI and includes AI features.This won me 1 year of GPT Pro at the codex event :)I hope you can tell... I'm tired of companies designing their products to lock you in, to charge you more, with no added value. I build software for people like me. So I'll be building more apps that replace this user hostile software.

  I'm developing a tool that will help you easily delete your data from services. It scans the subject line and sender email address of the emails in your inbox and suggests an email draft to help you delete that service. It's open source and self-hostable, with privacy and security as top priorities. I got the idea when Saymine.com was acquired by McAfee and became total bs...This is my first project that I want to release to the public, and the official instance will be free to use. I'll try to keep costs low without sacrificing service quality, and I hope to keep the project afloat with donations because I believe everyone should have the right to easily remove their data, regardless of cost or technical expertise. I don't have anything to share yet because it's still in the early stages of development, but it's looking good so far.

  I’m working on Descartes[^0]. First to help diagnose what’s wrong with a machine.I’ve started implementing actual background monitoring of the system, and next will be letting an agent build its own layers of tailor-made deterministic rules and statistical models, to "learn" what the system’s normal behaviour is and only "wake up" the agent when something unusual is going on. Either to update its rules and models, or alert the user.Like the ship’s AI at the beginning of Absolution Gap. Next will be enabling it to serve as the interface for the system. An ops "point of contact" for both the user and their agents for the machine / fleet of machines it’s in charge of.———I’m also working on third thoughts[^1], a tool that analyses local agents logs to find patterns and behaviours, identify what works, what doesn’t, how they evolve over time, using deterministic and statistical methodologies and techniques from multiple domains (including, to my surprise, genetics and psychology / sociology), with an agent layer that interprets the results.I’d like to add a "federative" layer where people can contribute the results, patterns, and findings, without leaking their logs or personal / private data, so that we can all better learn how to identify failure modes, predict them, and see what works and what doesn’t.———I’m also having Claude & Codex revive Jasonette[^2], which died off and was turned into some weird paid unrelated thing by those who picked it up. I’d been meaning to but never took the time. But now with agents…All rebuilt in Swift / SwiftUI on the iOS side, and Kotlin on the Android side. Some features are still missing, but it works quite well! [^3].———Oh, and Boucle[^4] is doing its thing on its own. No idea how it got to 100 GitHub star. My "autonomous dog-fooding expensive pet" is apparently more "internet successful" than I’ve ever been.And quite a few other side projects.———[0]: https://github.com/lightless-labs/descartes[1]: https://github.com/lightless-labs/third-thoughts[2]: https://github.com/Jasonette/JASONETTE-iOS[3]: https://github.com/Bande-a-Bonnot/JASONETTE-Reborn[4]: https://github.com/bande-a-bonnot/boucle-framework

  I've been continuing work on cardcast.gg. It gives you the ability to play Magic: The Gathering with your friends remotely using a webcam.In the last month or so I added a few nifty features:- Auto-scan functionality: Instead of having to click on cards to discover what they are, I can now do whole-frame detection on an interval (configurable), so players can mouse over the webcam stream of another player and automatically see what the actual card is. Super helpful for deciding who to attack and makes turns quicker!- Card view is now grouped by player, since auto-detection will populate a lot of cards during the course of a game.- Switch the video stream to Livekit from my homebrew version. Players were having video trouble and I hope Livekit is good enough so solve that problem.Next up: I really want to build a community around this, and I'm struggling on getting the word out to people / having them try it out. I've done some SEO and word of mouth advertising, but haven't had much luck. I feel like I need to switch directions a bit. I'm a developer by trade, so this is wholly new to me.Come check it out: https://cardcast.gg

  I have been experimenting more with agentic iterative optimization: using LLMs to actually speed up code by finding and testing lower-level optimizations, specifically by having it build a real-world representative benchmark, then tell the LLM to optimize that benchmark without a) cheating the benchmark and b) ensuring code quality by some metric does not regress, e.g. MSE for machine learning algorithms. This is extremely effective with GPT 5.5, and recently I found another prompt optimization (https://news.ycombinator.com/item?id=48413304) that surprisingly results in another 2x speed improvement on average.So far, I have mostly feature-complete implementations of the following, which are faster than the state-of-the-art implementations, up to 20x faster in some cases while matching or beating them in quality:- a new 2D data visualization library, along with more bespoke data viz implementations such as word clouds and Primitive.- programmatic image generation- image compression- a new statistical machine learning library, along with more bespoke algorithms such as UMAP and HDBSCAN- a novel modelless invisible image watermarking approach- a novel machine learning approach which may be a crime against data science but the performance is really good- local text embedding generation with MLX- image-to-ASCII art conversion- grep/jq replacement (faster than ripgrep)I aim to open-source them over the next months but the main bottleneck is the inevitable barrage of "gtfo AI slop" comments even if I dot every i and check every t, in addition to the distribution of new software being extremely difficult nowadays due to the death of social media and "20x faster" raising red flags even if I have the data to justify it.

I will be launching soon and can't talk too much about it yet because its quite novel. It actually has quite a few novel ideas within. Very minimal usage of AI in this project, I've been working on it for ~6 years now. A bit toooo long.- A pure slop-crafted browser extension, because I paid for claude code Fable and it got rug-pulled so I am burning my tokens on a 100% slop project just to see what hands-off coding is actually like. A slight distraction from project 1 I do when I'm feeling a bit burnt out. Super fun so far proc-gen type stuff. Derivative

I'm also making modifications to VLC and mpv so they can play these directly. I've had some success already, but I've discovered a few features of existing videos like Bandersnatch that I've had to go back and add into the specification.On top of that, it's lead me down the rabbit hole of a 1995 (limited) theatrical movie called Mr. Payback, which may have only ever existed on 50 sets of laserdiscs distributed to those theaters. I'm hoping to track down a copy of it... if anyone had any clues on that one, I'd love to hear them. I'd purchase a Domesday Dupe device and dump it. But it may be a genuine lost movie.

  I have been experimenting with methods of reading books and creating software for these methods.For example, I was inspired by the activeness of typelit.io when reading - typing out an entire book helped keep my mind from wandering when reading. But typing the whole book is too tedious. I wrote a few scripts to mirror the words on an epub, which does help with focus but isn't quite good enough.My current epub reader software I use requires you to press a button to reveal the next word. This has dramatically improved my reading comprehension, prevents inadvertent skimming, and keeps my mind from wandering.I'm still experimenting but for those who have ADHD or are borderline ADHD, it's quite a revelation - I can finally read without my mind wandering.
