What are you working on? Any new ideas that you're thinking about?
I am spending my free time doing a few projects to relax and "fix" a few things that should improve my productivity: - An AI RSS feed summarizer (https://feeds.carmo.io) - A PyObjC replacement for the bloated StreamDeck app (https://mastodon.social/@rcarmo/115498602604176483) - A new keyboard, mostly to get back into SMD soldering (https://mastodon.social/@taoofmac/115521815709828495) - A bunch of small MCP servers for other projects (https://mastodon.social/@taoofmac/115315732816298110) - A case for a little server (https://taoofmac.com/space/reviews/2025/11/09/1930) that will eventually run at family's out in the countryside and manage a few ESP32 boards scattered around I recently launched a daily word puzzle! It’s inspired by tile placement board games like Patchwork and crosswords. You rotate and move tiles to rebuild a broken crossword. It’s free, web based, and responsive. I currently have several hundred daily players and growing. My wife and I create the puzzles and I’m continuing to fix bugs and add new features. I just launched a ”community puzzle” feature to let players help build new puzzles. I’d love to know what you think! That's awesome!! It took 15 min and I gave up on some words. As a non native it feels awesome to finish a puzzle like this haha Really great! One of the things that Wordle did that I thought was very clever was having a copy and paste social media preview of how you did. It might be worth adding that for vitality... you could even add an image preview with Open Graph meta tags if you were clever. This is a lovely game! This game was Show HNed two times in ten days, [1][2], but unfortunately, it didn't get as much attention as it should! Ironically, this current thread has already gained almost double the comments from both submissions combined! I whish you best of luck to succeed in your journey. ___________________ Good fun. I discovered a big though. I could not yet reproduce it, but I managed to somehow have letters glitch out of the Tetris shapes they are in. When I move the tiles or rotate them, the letters are back where they should be. So it's not game breaking, but seems to happen in some case. At first I suspected, that it was because my phone was locked in between, but I tried that and when locking it manually, that bug did not happen. So no idea, sorry! Nice! Some feedback from my wife, who is into all manner of word games: she found it a little bit brute-forcey: needing to try all different combinations in order to get the right configuration of the word. In contrast to a crossword where there is already a layout, which gives her a hint for how to proceed with the rest. (She finished today's puzzle, and I gave up.) From a UI perspective it is very slick - very smooth, and I like how it kind of "gets" what you were trying to do when providing corrections/hints. >In contrast to a crossword there's a type of crossword called "diagramless" where you have the numbered clues and an empty grid there was one in NYTimes Magazine Sunday puzzle page this past weekend Nice! What might be a nice lesser 'clue' to simply revealing a word is highlighting letter(s) on the board that are part of it? Favouring maybe highlighting letters that are contiguous with a blue bit? This is really good. I like the idea of the game and your execution of it is superb. I saw your Show HN post a few weeks ago! Really appreciate the smoothness of your UI and the simplicity of your onboarding, I see how much you have dialed in. I've been working on a daily puzzle game too (it's getting there...), maybe you'd enjoy it https://slab17.com/ Slab 17 is a really interesting and unique puzzle! I love the act of slab creation. It’s very satisfying and the aesthetics are great. I found the instruction about double tapping a little confusing at first but figured it out as I played. Nice work! Thanks for the note and the feedback about the instructions! Got me to rework the wording. This puzzle is genius.The interface is minimal and user-friendly, everything feels smooth and intuitive. This is really fun — have you played with making the tile position opinionated (not agnostic)? i wonder if have the clues point to a starting square (e.g., "E5") would be better than the current "reveal" aid. The spatial information would become more helpful toward the end when the player is dealing with the words they need help on. Could you expand on what you mean about opinionated vs agnostic? It sounds interesting but I’m not sure I follow. I like that clue idea! I want to change how the reveals work. I’ll play with that! Very neat and clean UX, kudos to that! How do you market it – now or planning to, if I may ask? The animations in the interface make it feel more "jelly" and not "wooden" like a number of other such interfaces. Thanks! I spent a long time trying to make the core controls feel intuitive and natural to use The amount of care you put into it must be massive; a noticed so many nice subtle details that make interacting with the pieces easy and fun. Kudos! I love it. I struggle more than I want to admit, but super fun nonetheless. It definitely has a bit of a learning curve! In playtesting it sometimes took a bit for the rotation to “click” for people. Great game! The effort you put into animations and interactivity really pays off, especially when first learning how the game works. This is a classic HN comment but I’d love a Thursday/Friday crossword difficulty equivalent in addition to the dailies which are a ~Monday. Thanks! I would like to explore different difficulty puzzles in the future! Got tired of every single weather app and website being littered with ads. Half the time my weather apps don't load the weather maps but the ads work fine, c'mon! So decided to start my own; here's what I have so far...once I iron out the site I'll start on the Android app. Feedback welcome :) I've been working on an open-source containerized agent framework called Capsule Agents. Its built around 3 key ideas I've dealt with inside the agent ecosystem 1. Agents become far more capable when they have access to a CLI and can create or reuse scripts, instead of relying solely on MCP. 2. Multi-agent setups are often overvalued as “expert personas” but they’re incredibly effective for managing context, A2A is the future. 3. Agents are useful for more than just writing code. They should be easy for non-engineers to create and capable of providing value in many domains beyond software development. If that sounds interesting take a look!
https://github.com/brycewcole/capsule-agents I’m working on a free and open-source invoice generator: https://easyinvoicepdf.com/?template=stripe - No sign-up, works entirely in-browser - Live PDF preview + instant download - VAT EU support - Shareable invoice links - Multi-language (10+) & multi-currency - Multiple templates (incl. Stripe-style) - Mobile-friendly GitHub: https://github.com/VladSez/easy-invoice-pdf Would love feedback, contributions, or ideas for other templates/features. PS: e-invoice support coming soon Ha! I built a similar service for quote generation a couple of month ago: https://quotemachine.cc No signups, free for all, browser-only, live pdfs, etc Built it for a friend and decided to share with all, it's just a react app (no backend) running on GCP and costs almost nothing to run. Didn't think about opensourcing it and I will, why not. Nice work. I liked the instant pdf viewer. Kudos for your efforts. Only thing I would suggest is, to support different tax formats (or provide an ability to fill custom tax format name that applies to the whole invoice). Right now, it is largely VAT. In some countries, it may not be relevant. (Having said that, as a work around, currently anyone can use Notes field to fill custom tax details and hide all VAT related fields.) Thanks for the feedback, will take a look into supporting custom tax formats UPD: Created an issue to investigate Been working on my programming language https://github.com/buzz-language/buzz for 4 years now (with some down periods).
Currently mainly working on the tooling: LSP, DAP and formatter.
Also managed to get fuzzing working with AFL++ and found a bunch of bugs with it. I think by this point everyone that is learning a language knows that immersion is very important, however a problem I've had myself is that the content that interests me is beyond my reach, and the content that is within reach doesn't interest me. This is my attempt at doing something to remediate that. You select the content you want, and I create a personalized study plan to learn the most important words to achieve a target % of understanding. Then I generate a short story each week for your particular level containing the new words in the context of your content. The idea is to bring the content you want to learn to your level so you can watch what you want to watch. That's a great idea, and I live the UI! I wish I have some time now to learn Japanese now... Nemorize.com
Master anything with spaced repetition, WaniKani-style levels for every topic. Fully functional and constantly evolving. Currently working on a take on Pokémon GO + Pokémon Snap but for birding. The goal is to explore your neighborhood, find birds, take good photos of them all. Next month, I'll be doing an event to find a rare bird, excited to see how it goes! It's still a small closed alpha, if anyone is interested: https://testers.birdlego.com Here is a rough trailer of it: https://www.youtube.com/watch?v=yVpR8aafFjI I got super excited thinking this was for real birds. I would love someone to gamify birding. I guess it's not intensely gamified, but I have a couple friends at like 80-90% on Merlin. It's their excuse to travel and live abroad What’s missing from eBird? Certainly gamified a bit as I learned from: LISTERS: A Glimpse Into Extreme Birdwatching https://youtube.com/watch?v=zl-wAqplQAo 1.9m view | 2mo ago | 2hr long (buckle in, documentary by a couple young goofball brothers) I want something more gamified. I want to go on missions or complete challenges or something. Not just identity and log stuff. Oh I was hoping for this but with real birds in my neighborhood. Still neat! We have been building https://finbodhi.com/ a local-first browser app (PWA) for personal finance, based on double-entry accounting. FinBodhi uses double entry so complicated set of transactions and accounts can be modeled (which happen often enough in users financial journey). We wrote about double-entry here: https://finbodhi.com/docs/understanding-double-entry We do use online services like firebase for auth, and some service to fetch commodity prices etc. But all your financial data is on your system (we use sqlite over opfs, in browser). For synching across devices, that data is encrypted with your key before it leaves your device. You can backup the data locally (if you are using chrome) and/or to your dropbox. It's designed so that we (the people building it) can't access your data. There are many more features, like multi-currency, visualizations, a sheet to use your data to do complex calculations like taxes, planning for your future etc. Feel free to try it out with the demo account (no sign-in required). Note: app doesn't work in Firefox private mode. Cool stuff, happy to see that you focus on local storage. How do you handle uploaded financial statements? Are they sent to 3p? Import is done locally. No 3rd party is involved. We have build custom importer. e.g you can import a csv and map it's columns to what we need internally. We also allow some logic in importer. E.g. to figure if a row is credit or debit. etc. It should be feasible to import most csv statements. PDFs and Excels should also work, except for some complicated cases where a transaction is spread across multiple rows. There are a few custom importers also, for indian context. Continuing with my retro productivity software blog, Stone Tools: https://stonetools.ghost.io I was getting a little bored of retrocomputing discourse being so centered on gaming, so I'm exploring the productivity software of the 8/16-bit era. I put real effort into learning and using the programs, giving my light-hearted but heartfelt assessment of its form and function for both its time and today. Using the software inevitably gets me thinking about other things, and I explore those threads as well. For example, "Superbase on the C64" also discusses the legacy and promise of "the paperless office." A couple of other posts got some nice traction here on HN, notably "Deluxe Paint on the Amiga" and "VisiCalc on the Apple 2". I'm hoping to build a strong monthly readership, so I'm putting in the work. It's been up for two months and five posts now, with a new one coming at the end of this week. I think this software archaeology / history-keeping is really important. Keep up the good work. These paragraphs resonate with me: > There is utility in those old tools and interesting ideas to be mined. Recently I stumbled across something that by all accounts should have set the world on fire, but whose ideas needed more time to germinate before blossoming much later. Discoveries like this are not just nostalgic “what ifs” to opine wistfully upon, they can be dormant seeds of the future. > Computing moves at such an unrelenting pace, those seeds may lie dormant for any number of reasons: bad marketing, released on a dying platform, too expensive, or even too large a mental leap for the public to “get” at the time. I see this blog as a way to explore the history of the work tools we use every day. I don’t do this out of misty-eyed sentimentality, but rather pragmatic curiosity. The past isn’t sacred, but it is still useful. What's your research process? Do you use lots of Internet Archive material? Do you reference any personal artifacts i.e. old hardware or documentation laying around? Any interviewing? Thanks for the kind feedback, and I'm happy you felt resonance with those words. I use tons of Internet Archive material, but also stuff from various retro enthusiast sites which focus on specific hardware platforms. Lots of books, I look through YouTube for interviews, and include my own personal history with the machines and genres (I don't want the blog to read like a passionless how-to manual). If I had the physical space for a hardware collection I'd do that, but alas. No interviewing of my own, just research into existing interviews up to present day. The main point is really to let the software speak for itself and see if it and I can be friends. This is a neat project! I read the last post and I’ll work my way back through them. This is super cool. If it was RSS enabled I'd immediately add it to my feed! Thanks! I don't actually know anything about how Ghost blogging platform interacts with RSS feeds, but I get a small amount of traffic from personal aggregation services. I guess I kind of thought RSS is enabled, but I don't use it so I honestly don't know. I'll look into it and see if there's some setting or toggle switch somewhere I need to flip. A tool for creating custom Tailwind-style color palettes for web and UI design that pass WCAG contrast requirements: https://www.inclusivecolors.com/ The interface is optimized to let you quickly explore and tweak multiple tints/shades at once so you can customize all colors exactly how you want e.g. try dragging vertically through the saturation curve in one motion to edit all the tints/shades at once, or shift whole curves horizontally by dragging between the dots on a curve. It uses the HSLuv color space, where (unlike say HSL) the WCAG contrast stays the same when you change the hue and saturation sliders. This makes it much easier to explore accessible colors choices as you know only changes to the lightness slider will impact the contrast. You can also switch from the WCAG2 contrast checker to using APCA, which is meant to correct for inaccuracies in WCAG2, such as it being too forgiving for dark mode color combos. Note the mobile version is more of a preview and the desktop version has more features. I probably need to add something like a tutorial as there's a lot going on, but I've added more hints and tooltips recently. Open to feedback on what's initially confusing and what changes might help! I passed this on to some accessibility folks at a couple conferences in the last month - everyone was impressed :) That's awesome, thanks! I'd also keen to hear from people who are interested in accessibility but don't know much about it too. I've tried to explain the WCAG contrast rules in the simplest way I can (interactively, via the live mockup example on the right and contrast indicators that appear on the left) but there's quite a lot to cover. As a means to learn about both WebAssembly and Rust, I started writing a WebAssembly binary decoder (i.e. a parser for `.wasm` files) from scratch. Recently it hit v2.0 spec conformance. 3.0 is next on the roadmap. (I'm executing it against the upstream spec test suite.) My aim is probably not for it to become a highly-performant decoder for use in production environments, but rather one that can be used for educational purposes and/or debugging issues with existing modules. That's why I decided not to offer a streaming API, and why I'll be focusing on things like good errors, good code docs etc. P.S. I'm new to the language so any feedback is more than welcome. Plug-That-In [https://plugthat.in] (Mac App; Paid) An annoying little laptop charging reminder utility that does the job. --- There are times when I am deeply involved in a focus-work session, a meeting, OR watching some sort of engaging video content, and don't pay timely attention to the standard low battery notifications from my MacBook. After the laptop shuts down suddenly, what follows is the most annoying walk to find the charger or the charging outlet. It's frustrating at times, sometimes embarrassing because you have to say, "Sorry, my battery died down" as you join back the session after 2-3 minutes. Over the last 3-4 weekends, I have been building Plug-That-In, which has floating notifications. Essentially, a notification that follows my cursor movement, so I get a stronger nudge irrespective of what I am doing. There are a few other critical features, such as Reminder Mode and Do-Not-Disturb Settings. - Reminder Mode: On critical/lower battery levels, it will keep beeping like a car's seat belt alert for some time (configurable) when the battery is really low. - Do-Not-Disturb settings: Configure what sort of alert/sound it will generate when I have system audio playing or video playing, or the camera is active. It has addressed a personal need and has already proven useful a few times over the last weeks. The software engineer in me wanted a break, but the philosopher and systems thinker wanted to speak. So I've been building something with no imported libraries or dependencies: a card game that gamifies Maslow's hierarchy of needs: https://gamefound.com/en/projects/nicomar/actualize-this Each player drafts cards that represent ways you can spend your limited time on earth to gather resources (wisdom, gold, and virtue) to complete your own personal player board (your hierarchy of needs) with the goal of reaching self-actualization before other players. However, you can still win without becoming self-actualized, if you complete more hidden quests (which can only be discarded by the "therapy session" card). I have to say, i love this. The name is fantastic and the whole concept. It's got a very Game of Life or Monopoly feel where you've just taken the fundamentals of something in society and turned it into a game instead of adding an additional story on top. I really like it. My one comment would be, I think you need to change the branding a little bit. It's a bit too close to Magic the Gathering, and this feels like its own IP and can stand on its own legs. So I think you need to just adjust the cards enough so they don't instantly read as a Magic the Gathering card. We developed a novel optimization pipeline for LLMs so large models can run on a standard laptop. Our first prototype optimized an 80B model to run at full 256k context at 40 tokens/s while only taking up 14gb of RAM. We are currently leveraging this tech to build https://cortex.build a terminal AI coding assistant. Working on https://slingdata.io
Platform for moving data around. Also has a free CLI. You can use YAML or even Python. Dog enrichment calendar - I have a lot of different types of treats, toys and activities that I'd like to do with my dog but I fell into routines and just gave him two or three toys and treats on repeat. So I'm building an app where I'd be able to configure an inventory of all the treats and toys I own and the app would remind me to use a new toy or treat every day, to minimize repetition. You'll also be reminded ahead of time for toys and treats that require preparation I was tired of repeat, sponsored, and "safe" music suggestions from Spotify, so I built a discovery engine that puts the control back in the user's hands. The core idea is simple: You define a "Discovery Model" with explicit constraints (specific genres, release years, track popularity, etc.). The app then uses this blueprint to source tracks. The results are fresh for two reasons: - "Known" Track filtering: Excludes all songs saved in your library and recent listening history. - Active Curation: Uses your custom model, not a vague, opaque algorithm. It’s built with a local-first mentality and a focus on privacy. No black-box AI "vibe" mixes, just pure, objective discovery based on your criteria. Hope ya'll find some new gems! I canceled my Spotify subscription because it would not let me "reset" the algorithm to get fresh suggestions. A "discovery algorithm" that I used (works great for jazz) consisted on looking up which musicians played on an album that I liked on discogs and searching for more albums from them. I am building Mizu, a lightweight web framework for Go that aims to keep things simple and Go-first. Everything is written in plain Go with no hidden abstractions, and you can start with a single file then grow into a full project without changing your coding style. The name means "water" in Japanese; the framework tries to flow with your code rather than force its own patterns. Since I got a baby and we’re still adjusting to their schedule, I’m still working on the same project, Librario[1]. Librario is a simple book metadata aggregation API written in Go. It fetches information about books from multiple sources, merges everything intelligently, and then saves it all to a PostgreSQL database for future lookups. You can think of it as a data source, or a knowledgeable companion that can provide comprehensive book information for online booksellers, libraries, book-related startups, bookworms, and more. I got a pre-alpha build running for those that want to test it out[2], but the code is still not out there, as there are a few things I want to refactor. Wrote comprehensive documentation for it this weekend, now I need to refactor the merger package with some new rules, and write something to decrease the number of genres returned. Been tough to find time to work on it because of the baby, but AI has been helping a lot to speed things up, and the work has been quite fun. Not sure if there will be interest in the idea, but it solves a problem I have, so I had to work on it anyway. Hope to have the code on GitHub by the end of this week. AGPL licensed.

I’ve been working on https://canine.sh which is a free, open source Heroku alternative for 2 years now. It’s exactly the product I wish I had when I started my previous company. Running on PaaS is incredible for devex but the pricing is bonkers, and the vendor lock in makes it really hard to deal with annual price increases. We spent close to 400k / year for just 128GB combined fleet in our last startup on Heroku. Canine tries to get the best of both worlds: developer friendly PaaS with no lockin or price gouging. Just added build packs as a build option recently. Also got a sponsorship from the portainer folks which lets me work on this close to full time Hoping this saves someone the headache I had two years ago. It's an explorable database of films, TV shows, books and board games based around their historical setting: where and when the thing is set. It's been incredibly complex and interesting getting the (messy) data, making sense of it and trying to design a UI to explore it. https://stevebennett.me/2025/08/26/whenever-exploring-times-... It would be interesting to see for movies and tv series where it’s set vs where it’s actually shot This reminded me instantly of Every Frame a Painting's video "Vancouver never plays itself"[0]. Yeah, that's a whole different thing. I saw this map once that showed places in California and how they were used to film various locations around the world. Turns out LA is very well situated. Discovered in-door bouldering / rock climbing and now go 3x a week, am absolutely loving it! Because of that, I haven't really worked on any side projects in a while. Perhaps I don't need to? My job advances me plenty in my field, but it is a bit of a bitter-sweet feeling in a sense, like maybe I should try to squeeze more out of my free time somehow. I climb a lot! (Actually currently sitting on Big Sur ledge on el cap posting this).
It cuts into my free time programming for sure, but imo super worth it! Enjoy it, it’s a wonderful hobby. I’m replying from the cold east coast (from the edge of a wood chair in a lovely iykyk type of restaurant) to a human posting from el cap on hn; We have achieved peak technology. Oh yeah, I’m working on urban logistics, powered by AI. I’ve been hesitant for fear of injury harming the ability to type, but might give it a go in the spring. Thanks for mentioning this I’m inspired to try it finally. I struggled with hand and wrist pain for years from spending too much time at a computer. I did physiotherapy for years and while it helped me manage pain, I was never able to truly build enough strength to get ahead of it until I started bouldering. I took it very slowly—I spent months on very easy problems—but because it was so much fun, I kept going back. Initially, I would only go on Saturday mornings, so I had the full weekend to recover before jumping back into the work week on Monday. After a two or three months of that, I was able to climb anytime I wished. I'm still not a particularly advanced climber, and I typically only go once per week, but I am still slowly progressing, and I absolutely love it. Couple things to avoid finger injuries: go easy on one- and two-finger pockets, use an open crimp whenever possible (all finger joints are bent the normal direction, and your palm/thumb aren't really involved), and don't bother with the hangboard or campus board for the first ~year. I wouldn't worry about it too much though - almost all of the people I know with finger injuries were trying to push into really being competitive climbers, not just doing it casually for fun/fitness. Oh also to keep from tearing your skin don't climb tired. (That won't keep you from typing, it's just painful.) I'd like to add to this that do not make any food with chilli peppers like habanero or such if you just came from the gym with torn skin. I found out the hard way. I’ve been climbing for 20 years and it’s the thing that prevents RSI for me and makes it possible to use a computer too much :). Certainly possible to injure fingers but would be a very rare climbing injury that would threaten coding. Climbing easy routes in a gym is pretty low impact. It’s only when you start to move into really hard crimps or slopers where you’ll hurt yourself. I was a climber bum for years and have climbed crazy stuff around the world and never hurt myself to where I couldn’t type. A lot of bloody tape, but still able to type. I love the intense concentration for martial arts, but I had to stop because of this. I never had a serious injury. Instead it would be minor injuries, that would make my ring finger 20% less responsive, that would totally mess up my typing cadence. I tried capoeira, a non-contact martial art, for a while. This wasn’t as good for me as Taekwondo. Try top rope climbing! Bouldering is injury prone because every fall is a ground fall. With top rope climbing you should never hit the ground so way less injury prone. I've been enjoying the breadth of projects made possible with AI, I've cataloged over 200 of them created in 2025 here:
https://jonathanclark.com/posts/ai-coding-million-lines-2025... A few of my recent favorites:
- swim lap counter in html/JS that uses the camera to watch you swim and count laps/timing
- video recorder that records your window/desktop and uploads a file to S3
- video conferencing app that allows a 2 year to click on a family member face and initiates a video conference using webRTC, STUN, and browser audio/video capture with automatic bandwidth adjustments (works on all platforms with pure HTML/JS).
- CUDA based ray tracer with HTML UI that can trace over 2m rays per second on my laptop for scientific study, allowing real-time display of optical parts.
- chat front-end for image models like gemini-pro and openai that take other images and text as references and generate a big library of options to chose from in seconds, I've been using photoshop for decades but I tend to use this more now. > CUDA based ray tracer with HTML UI I'm curious if you mean they're running a raytracer on the back end, and you interact with an HTML UI, or if it runs browserside, maybe via WASM. AFAIK CUDA isn't directly compilable to WASM (yet?) I have a node middleman that proxies request from an HTML/JS front end to a native cuda process using web sockets. To support multiple windows, the node process process provides communication between two browser windows. This lets me have render a model using 3JS in one window and a ray traced version in another window. Woah that's a lot of projects. Would be cool if you could open-source some of them. +1 to this, not all of them of course, but there's some very useful ones in there I could make use of. I’m building RootCX (https://rootcx.com). A customer "operating system" replacing dozens of SaaS tools. As a second-time founder, I've watched the SaaS boom create an ocean of best-of-breed tools. Each solving one slice of the problem. One solving it end-to-end. Now every company runs on a patchwork of apps, APIs, and workflow hacks just to keep customer context alive. It's insane how normalized that's become. RootCX starts from the opposite premise: the customer is the core, not the app.
Everything: CRM, support, billing, workflows, AI, ... plugs into one shared customer base. Less juggling tools, more actually running the business. I’m working on “Stripe Integration as a Library.” It seems that whenever someone uses Stripe, for example for subscriptions, they go through the same few steps: creating a database table, setting up webhooks, and implementing the events they care about. The challenge of course is that everyone uses a different stack. I’m building this using our framework for stack-agnostic JS/TS libraries. On the database side, we currently support Drizzle and Kysely, with Prisma support coming soon. https://fragno.dev/docs/our-fragments/stripe/quickstart Inspired by the Stripe integration built for better-auth. FreeBSD 15.0. Rather depressingly, almost everything I said two months ago is still true: https://news.ycombinator.com/item?id=45419134 But I'm hoping to have it out by the first week of December. Working on a charity + website (not live yet) that allows you to centrally manage your charity donations. I'm in Germany so I'm working on a Germany-specific solution for now. - you choose from a list of charities (right now I'm working with the list from the https://dzi.de plus a few such as Wikimedia Deutschland) - you setup a recurring donation to our bank account - we redistribute the money according to your split - no spam in your email and snail mail - one pdf at the end of the year for your tax returns I'm not planning on taking any cut of the donations obviously, so this will be a fully self-funded project at first, but I'll reach-out to foundations once I'm up and running. The URL will be https://super.giving/ (not setup yet, should be fairly soon). I'm also planning on releasing the source code as open-source. I'd be happy to hear your feedback, either here or via email :) Building an MCP Gateway: https://www.gatana.ai/ Idea came from one of my clients, where they wanted to use AI agents throughout the organization but at that moment there was no centralized governance or security concepts. This pulls everything at one place and tries to solve the security concept with per-user credentials, which can be provided out-of-band through the MCP protocol (generated a one-time link end-user can use to sign in to the underlying MCP server with OAuth or provide API key) I built a wireless highlights & annotations export service for Kobo e-readers earlier this year [1]. Had a free tier limited to 20 exports but wasn't sure how to price it beyond that, so I just left it. Recently a user reached out asking if I'd settled on pricing and how they could pay for unlimited exports! That jolted me into coming up with a price, and now I'm finally getting Stripe integrated :) [1] - https://highlights.email Creativity and game development clubs for kids: https://breaka.club/blog/why-were-building-clubs-for-kids Basically, I'm building tooling and providing these to community run clubs that help turn kids from consumers into creators. I'm focusing on game development initially, but have plans to expand into other areas of creativity. We're using Godot + GodotJS (which I'm a maintainer of): https://breaka.club/blog/godots-most-powerful-scripting-lang... I've much experience building software for creators. I'm a (core) developer of Tabletop Simulator. I worked at a now defunct startup which allowed people to create and distribute their own interactive fiction stories using partner third-party IPs. I have a background in EdTech. I used to be Head of Engineering at Ender, where we ran custom Minecraft servers for kids: https://joinender.com/ and prior to that I was Head of Engineering at Prequel / Beta Camp, where we ran courses that helped teenagers learn about entrepreneurship: https://www.beta.camp/. During peak COVID I also ran a social emotion development book subscription service with my wife, a primary school teacher. Spent the last three months building a competitor/lookalike ML model + API. Started using plain embedding similarity and quickly realized you end up with similar noisy results as ocean.io. Ended up using similarity learning which works quite well with little data. Launched this as an API and small web app. Hardest part right now is to fend off scrapers honestly. Examples: - YC: https://markets.apistemic.com/companies/y-combinator-goaq9 - uber: https://markets.apistemic.com/companies/uber-com-ojj2j - Anthropic: https://markets.apistemic.com/companies/anthropicresearch-yx... Try it for any company here:
https://markets.apistemic.com Built a local-first Kanban board with Tauri (Rust + Svelte) after getting frustrated with SaaS tools and basic offline options. Stores data in JSON files you control, full keyboard-first UX, parent/child tasks, release management, and it's blazingly fast with localStorage + background sync. No telemetry, purely local. Curious what others prioritize in personal task tools. Seems like there's a gap between "todo.txt" simplicity and Jira complexity. I wanted to build something like that. It would be great if I didn’t have to. Any link to follow? Cool. Love Tauri. So the whole board dataset is stored in localStorage? If you get to a point where the size limitations or synchronous blocking operations are an issue might consider using IndexedDB. There is a nice higher level wrapper around it called Dexie that has full TS typing support and a nice async API. https://dexie.org/ I’m still using redmine. It allows me to create a project, break it down in to tasks, assign time estimates for the tasks, assign % complete, log time against tasks, which then allows for burn down charts so I can see if I am on track or behind. With time logged against projects I can generate timesheets and invoices. It also has Gantt chart which is handy for initial project planning meetings. Porting Ruby to Fil-C It's very interesting because the Ruby codebase uses a `typedef uintptr_t VALUE` type to mean any of the following: - A pointer to the heap - A Ruby tagged value (which may be a pointer to the heap) - Any integer value that fits in `uintptr_t` Fil-C doesn't allow you to carry around pointers using integers, in the sense that when you do that, the pointers lose their capabilities. But in Ruby's case, it's not as simple as changing the typedef to a pointer type, since `VALUE` variables often end up being used for integer math (including bit math, shifts, etc). So, it's going to take a nontrivial patch to Ruby to get it to work in Fil-C. I think I'm about 70% of the way through (I started Friday afternoon). Working on a programming language for webapps! Speed is not an optional feature on the web. The site above is written in Firefly, uses hydration, and scores 100% on PageSpeed Insights. The language is largely complete, and we're now working on DX: Got a language server, a devserver, and some essential libraries. This looks good! It feels a little bit similiar to ReScript. I like the idea to have nodeMain, browserMain and buildMain. The Roc language had something similiar with platforms and I love that idea! In general I prefer a better language over an involved javascript framework that does not look like js anymore. Running OpenStreetMap off the grid (self-hosted to say the least) on a Raspberry Pi 500 (and to some extent a Pi Zero 2W) for Internet In a Box: https://www.linkedin.com/posts/danielkrol_openstreetmap-acti... All of the street and satellite tiles are thanks to maps.black. The search uses Nominatim's sqlite3 mode. I was told that it's experimental only because it hasn't been tried in production yet, so I'm sort of testing it in the process. So far I'm only doing administrative boundaries and natural features, but so far so good! I'm going to slowly add a few more types of POIs, I just don't want the database file to get too big. Note that Internet in a Box has an OSM offering already, but the data is five years old and the tech makes it harder to update. As of today, there are much easier options on the table, and we get cool stuff like 3d buildings. Also, the search was much more limited. * https://internet-in-a-box.org/ * https://nominatim.org/release-docs/latest/customize/SQLite/ Raptor - a new (Free software) way to build things like: * Disk images * Liveboot isos * Container images (docker/podman) Many build products are supported, with more on the way: https://chrivers.github.io/raptor/builders/index.html#compat... It uses a syntax that is inspired by Docker, but significantly enhanced. Take a look at: * The project: https://github.com/chrivers/raptor/ * The book: https://chrivers.github.io/raptor/ Working on a low cost, miniature Bluetooth tracker. The inspiration was my parents keep losing (forget) their spectacles in the house. I wanted to build something that is very easy and simple to use and it was important to keep it small. SO the form factor is something like an airtag but 10x smaller which can be just stuck on to the spectacles and forget that it exists. Next step, obviously is to build a simple app that shows the location of this tracker with a range based on the Bluetooth signal strength. A few months ago, I saw a tweet from @awilkinson: “I just found out how much we pay for DocuSign and my jaw dropped. What's the best alternative?”
Me being naive, I thought “how hard could would it actually be to build a free e-sign tool?” Turns out not that hard. In about a weekend, I built a UETA and ESIGN compliant tool. And it was free. And it cost me less than $50. Unlimited free e-sign. https://useinkless.com/ Just to play a bit of shark tank, why would I use your tool instead of Docuseal, which is FOSS and self host able? Been working on https://usedigest.com - It's a personalized newsletter for you - All data aggregated from sources around the web - News, weather, newsletters, social media posts, reddit, youtube, etc. all appear in your digest. - Launching a mobile app as well now but this will be slightly different than the web app. It will use AI to automatically prepare your daily digest based on preferences/settings you give it during onboarding. Each day when you wake up you'll receive a notification of digest being ready, and it will contain all the content you care about for the day ahead (meetings, weather, health data, commute data, news, etc). I'm making Easel, a 2D game programming language designed to match how humans, not computers, think about game logic. It also has automatic multiplayer. I've been working on it for 3 years! Easel feels like a declarative programming language even though it is imperative, because lots of useful game-oriented features are first class. Like behaviours - you just say `on Pointer { ... }` and you have a concurrently-executing coroutine that's lifetime is managed. But you don't think about any of that complexity, you just think of your entity as having a behaviour and go forth and make your game. It also happens to have automatic multiplayer. Normally with multiplayer you have to worry about doing everything in a "multiplayer safe" way (i.e. be deterministic and only modify the things your side has authority over). My idea was to put all the multiplayer stuff in the programming language itself, underneath all your lines of code. This way, anything you write in that programming language can just be made multiplayer, automatically. So you can just pretend all your players are in one shared world, like a singleplayer game, and the engine does all the multiplayer for you. It was really difficult to make but it makes multiplayer so easy for you now. Easel is my idea of how games should be made, or at least as close to the idea as I can achieve with 3 years of work, and I would love for more people to try it out. This is really cool. Nice project! I tried doing something much more rudimentary before. Will be following Oh, thank you! I would love to hear more about what you were trying to do with your project before. Was it more similar to the declarative coding part, the automatic multiplayer part, or something else? Part of why I'm doing this is to explore the design space of how games should be made and I'm interested to hear what problems, issues, pet peeves, "bugbears" etc that other people think are worth solving. It's been a while. But I believe what caused me the most headache while trying to build something like this was handling the interactions between different elements. Declaring which objects were affected by "attacks" or could be "player interactive" or "affected by player but not by NPC". Really this boiled down to proper inheritance. But I found myself so deep and tangled a fresh reset would have been better. Then determining if the object itself or an "objective manager" should perform the calculation each cycle.. etc It was messy. I ended up having NPC, Item, Attack classes and for each a NPC Manager, Item Manager, and Attack Manager to calculate all their interactions and states. That's why your project seems interesting because it seems to handle the heavy lifting of behaviors and "behind the scenes". I've actually just recently been through this myself. I'm also building something for kids to build games in. But much more opinionated than Easel. It's interesting to me that Easel looks declarative but is imperative. I've actually gone with a 100% declarative approach. Basically you define effects, which are executed in response to certain interactions. There's a comprehensive targeting system. But the best part is this is all type-safe using TypeScript, the declarative structure is enforced. That means even when you chain effects, nested effects are able to access (incl. autocomplete) the targets of parent effects etc. Whilst this provides a super nice experience to consume, it's definitely non-trivial to build this system. Oh yes, handling interactions and dependencies and what is affected by what. I did a lot of React development (as in the frontend web framework) before making Easel and was quite inspired by how it hooks to change. The way you give it a little routine, it says what it depends on, and then it just fully re-executes that whole routine when the dependencies change. So in Easel when you say `with Health { ... }` it makes a behaviour that re-executes every time the Health changes. But, if it just reran the behaviour, then you'd end up with it adding a new sprite (for example) every time it re-executes, until you've got hundreds of them. So the other trick is the Easel compiler assigns an implicit ID to things like sprites so that it will replace rather than add the second time around. It's built into the programming language so you don't see it (most of the time). It actually took me 2 years to come up with that, which is both cool and depressing when I can explain it in one paragraph. Building https://floxtop.com/, a Mac app that organizes your files and images. It looks inside each file to see what it’s about, then moves it to the right folder with a single click.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers. It already works with images, Office (Word, Excel, PowerPoint) PDFs, ePubs, text, Markdown, and many other file types (30+) in English. Next I’m adding multi-language support. If you have messy folders anywhere on your Mac, Floxtop can help. Try it for free - requires macOS 14+ with Apple Silicon:
https://github.com/taranntell/fallinorg/releases/download/1.... It's cool to see this. I once saw an X thread on this and hacked a dirty tool for it: https://x.com/priyankc/status/1893112673434222985 I’m working on Alaska, a serverless compute platform I built entirely from scratch — no Kubernetes, no existing orchestration layers. It can spin up dozens of containers in parallel in just a few seconds. The platform is designed around a fast feedback loop — you write code locally, test instantly, and run it remotely with minimal friction. There’s a Python SDK that uses decorators to define what runs on the platform, so your local functions become distributed services without extra boilerplate. I also built a custom filesystem using FUSE to handle code, data, and runtime synchronization cleanly across nodes. It started as a personal exploration of distributed systems, but it’s grown into something that feels genuinely exciting! It's created by a developer for developers. Planning to open it up for beta testing soon. I've been working on a 3D voxel-based game engine for like 10 years in my spare time. At this point it's getting pretty close to being shadertoy for voxels. https://github.com/scallyw4g/bonsai I recently ported the terrain generators to the GPU, and increased the visible volume to 1 billion voxels cubed. I did a short YouTube video about it. https://www.youtube.com/watch?v=bLfgjWsM1PI I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better. An algorithm to optimise vacation days using public holidays and weekends. Especially relevant at this time of year. I created it a year ago and received quite some comments on the Show HN post[1]. Last weekend I updated it to work for end of year planning and adding fixed days off, which seems to solve most of the feedback. It was done with Cursor in agent mode. About 2 years back I began working on a very simple markdown compiler, it was “immediate” in that it would consume markdown and immediately spit html. That project turned into a whole static site generator called Kevlar — https://github.com/aadv1k/kevlar Entirely built from scratch in C without any dependencies. Now I wrote this code when I was 16, so many memory leaks and generally issues that I wanted to rectify and begin using third project for my own blog (currently old version is used — https://aadvikpandey.com) The Kevlar v3 (https://github.com/aadv1k/kevlar/tree/kevlar-v3) here is all that it includes; more spec compliant markdown AST-based parsing; A better .ini config parser (right now it’s literally strtok on ‘=‘ and generally very hacky) as well as name spacing; more powerful templating tags like IF, FOR with lisp-like configuration Of course staying true to the spirit of “from scratch” :) Honestly I did scope creeped a little since I mainly wanted to fix a memory leaks issue in the markdown compiler lol; anyway I will share it once it gets completed on hacker news :) > Entirely built from scratch in C without any dependencies. Now I wrote this code when I was 16 Very few young folk are learning C; I think it is commendable that you are. You code doesn't seem very strongly structured (to be expected, TBH) but much better than any learner would see. What resources did you use to start learning C? I ask because it looks to me that those resources covered "how to program in C" but not so much design and structure. Here's two links (my own blog) to get you started on one or two common C patterns designed to minimise bugs: Hey, thanks for your comment :) I had a look at your blog, it's looks really useful and high quality! I will go through it with vim open on the side and a nice coffee Yeah and I'd agree with your point. One BIG critique I have for my own 2-year-past code was that I did not know how to do dynamic heap allocation very well, hence you may have seen everything is stack allocated lol Particularly egrigeous example: So with the V3 release, I am re-writing the markdown compiler for instance, and being a bit more mindful of the structure Example: https://github.com/Aadv1k/kevlar/blob/markdown-compiler-rewr... I think once I am done I will create a separate "Show HN" post to get valuable feedback (like this one!) from smarter folks than me. Once again, thanks for the fantastic blog :) will be sure to go through it Cheers! When someone dies, you don't get even one extra second to access the documents and information they meant to share it with you. Trying to fix this problem with Eternal Vault. Link: https://eternalvault.app Another thing thats in early alpha right now is CapKit, AI professional captions for short form videos Eternal Vault is interesting. I would for sure use something like this. However, only if there is a strong story how the vault will survive 20+ years, even if your company is defunct. I do see the pieces scattered around the website (backup to Dropbox, etc), but this story needs to be front and center. Hi Luke, thanks for the feedback. Will be working on improving the marketing site to share the story in better way, any other feedbacks are also appreciated.
Lastly, would love for you to give the platform a try at https://dash.eternalvault.app/register I'm working on Pocketdata - a personal, private AI data plane. The idea is to take boring components: PostgreSQL, Bifrost (LLM gateway), Open WebUI, LanceDB, Agentgateway (MCP and OpenAPI gateway) and deploy them in Fly.io. One Fly.io "org" per user. The closest equivalent is blaxel.ai, but it caters for AI SaaS startups, not individual customers. The combination of the fact that Fly secrets are visible only from within the apps, distroless containers, and transparent data encryption for PostgreSQL assures that the service (Pocketdata) provider cannot access their data, only the infrastructure provider (Fly.io) theoretically can, but practically speaking, this gives an extremely high degree of privacy assurance. The latest update on the project: https://engineeringideas.substack.com/p/tasklet-is-the-o1-mo... Hey! Your project looks very similar, from a conceptual point of view, to what I'm doing with https://github.com/superegodev/superego. Would you like to have a chat about it? Email in my profile, if you're interested. TinyETL. Fast, zero-config ETL in a single binary. Transform and move data between any format or database instantly. No dependencies, no config files, just one command. Really nice idea. Have you tried tabsdata and they're implementing with Rust with Python binding, with around 100 MB standalone binary [1]. It advertised as pub/sub for tables but it can perform ETL as well. [1] Tabsdata: Pub/Sub for Tables: Building the world’s first “Travel Confidence Engine.” I’ve been obsessed with how people actually make travel decisions — not how platforms think they do. From a consumer’s standpoint, travel isn’t just “search → compare → book.” It’s emotional, contextual, and full of FOMO. You open 20 tabs across Booking, Google Maps, Reddit, and Instagram trying to answer simple questions like: Is this the right area? Is this hotel actually good? Am I missing a better deal somewhere else? Most existing tools either oversimplify (like ChatGPT giving three confident but unverifiable answers) or hide information behind algorithms and commissions (like OTAs). Both remove choice — and ironically, make people less confident. I’m building SearchSpot, a “Cursor for travel.” It automatically does what power travelers already do manually — cross-check reviews, verify real photos, compare prices across platforms — and then shows its reasoning transparently so you understand why something was recommended or excluded. The goal isn’t to replace your decisions, but to help you close your tabs with confidence.
From FOMO to flow. From chaos to clarity. If you’ve ever spent hours researching a trip just to end up more confused, I’d love your thoughts: https://searchspot.ai/home Why does it need a login though? big friction to just see the result of search yeah, but there's no way to reach out for feedback or follow ups if not logged in. At this stage, we want loads of feedbacks and help genuine users plan their trips well, hence the login wall. Still very focused on making light healthier. 3 new products: Bedtime Bulb v2[0]: A massive improvement over our original Bedtime Bulb, a light bulb meant for use in the evening to reduce blue light. The headline feature is the re-introduction of infrared, which was removed from lighting to make it more efficient, but emerging research suggest it's beneficial for health. After a long wait, this is shipping in 2 weeks! Atmos Bedside Lamp[1]: A fully automated circadian lamp that automatically shifts in color and brightness throughout the day, helping you prepare for sleep and wake up more naturally. Working on some machine learning features that mimic the functionality of the Nest Learning Thermostat, but for lighting. The first units are shipping by Christmas. Circadian Mode for Philips Hue[2]: A web app that gives your Philips Hue lights circadian powers, so that they gradually shift from bright light during the day to dim, low-blue light at night. It's way more powerful and easier to use than first- and third-party options from Hue, Apple, and Home Assistant. Just launched this week; looking for beta testers to give feedback!

I'm building a tool for managing Google Ads campaing called Rudys.AI: - Search campaigns:
- automatically crawl website, find the offerings and generate new campaigns
- Provide qualitative recommendations such as, relevant terms to include/exclude, e.g. including typos as keywords, improvements on landing page - Shopping campaign:
- Smart labeling of all products to allocate the budget among Top performers, Rising and Ghost products to avoid draining the budget. E.g. instead of a campaign with 10k products with one budget , turn it into 5 campaigns with different budgets doubling down on what works. Feel free to reach out for a demo I’m working on a quantum simulator written in C++ from scratch. I’m not using any external library, so I had to implement everything from the lazy eval structure to the eigen solvers and so on. It’s still very a WIP, but here’s the repo: https://github.com/braketware/hilbert-qusim Any feedback is welcome! I built this: https://github.com/dvcoolarun/web2pdf — a CLI tool for converting web pages to PDFs, recently open-sourced after adding several new features. (Might be useful!) Not related to the thread, but if anyone is looking to hire a developer or knows of opportunities, I was recently let go and am actively searching. Any leads or feedback would be greatly appreciated. Sample PDF: https://drive.google.com/file/d/1n7M1TKOptSsYiibrbvV_Yojx53T... In progress: I’m writing a book about how the brain processes text in general - and news articles in particular. I also created and maintain a Russian "newspeak" dictionary: https://github.com/alamzin/az/ Resterm - Terminal client for HTTP/GraphQL/gRPC. It includes support for WebSockets, SSE, workflows, profiling, OpenAPI, response diffs and many more. I'm working on Solitairle – a Yukon solitaire game where every board is guaranteed solvable: https://solitairle.com Why? Most solitaire apps frustrate players with impossible games or endless randomness. Solitairle is designed for people (like me) who want a satisfying win through skill, not luck. Every day brings a new, solvable challenge, complete with helpful tools (back button, dead-end warnings) to keep it fun and frustration-free. I’m especially interested in feedback from people who: Enjoy casual puzzle games but get discouraged by unwinnable setups, Value clean, minimalist interfaces without ads, Have ideas for daily challenges or fun player stats. Would love your thoughts: What frustrates you most about digital solitaire? What would make you want to play daily? I'm working on Flavia, an ultra-low latency voice AI data analyst that can join your meetings. You can throw in data(csv's, postgres db's, bigquery, posthog analytics for now) and you just talk and ask questions. Using cerebras(2000 tokens per second) and very low latency sandboxes on the fly, you can get back charts/tables/analysis in under 1 second. (excluding time of the actual SQL query if you are doing bigquery). She can also join your google meet or teams meetings, share her screen and then everyone in the meeting can ask questions and see live results. Currently being used by product managers and executives for mainly analytics and data science use cases. We plan to open-source it soon if there is demand. Very fast voice+actions is the future imo This sounds amazing. A demo video would help me finish sign up - I can’t try it without hooking it up to real data, and I don’t want to for a test. Great feedback thanks! We have added a synthetic e-commerce dataset as an example when you sign up so you can test it without your data first. Will also add a demo video ASAP. What kind of plan do you have with Cerebras? It seems like something like that would need one of the $1500/month plans at least if there were more than a handful of customers. They introduced pay as you go recently. The limits on that is similar to the plans, 1 million tokens per minute, so if you stack a few keys and do a simple load balancing with redis, can cover a decent amount of traffic with no upfront cost. Eventually we would have to go enterprise though yes! Recently launched my free app for gardeners to share plants with each other, Plantshare. Now I'm working on a few changes to the app, most notable is moving any plants marked as 'for sale' out from the main section because it turns out people are more greedy than I anticipated and it's getting in the way of sharing the free stuff, cuttings etc. There's also some demand for a web front end so I might work on that next. (currently only android and ios) I had an initial boom of downloads in South Africa but lately most new downloads are in USA. My own blog, which I mainly write for myself. But it is getting steadily more readers. Last week I wrote some scripts to help me with creating OG images quicker. Tech: - Zola, static site generator made in Rust - Swift, writing scripts for custom generating stuff - HTML and CSS - Cloudflare Pages Finally making a simulation of my heat engine. It's kind of like stirling engine, but working on entirely novel cycle, theoretically should be able to achieve over 80-90% efficiency (yes, more than Carnot theorem says). I had this idea for 15 years already, but didn't have enough free time to make prototype. Now I don't have much time, but thanks to AI I have kickstarted simulation program (it told me which equations to use and how, I do most of my programming myself), turns out it's not as hard as I've imagined when you know which equations to use. Still working on it at max several hours a week because I have two other programming jobs. If it works, it will noticeably bump humanity on Kardashev scale. carnot theorem does not put an absolute limit , a carnot cycle can have any efficiency as long as you have reservoirs hot and cold enough , besides that if you could be more efficient than carnots cycle at two temperature you can spontaneously extract heat from a cold object and out it in a hot object without any input energy , this would mean you can have perpetual motion . we are not just going to bump a kardashev scale , were going to truly max out and go beyond. fun fact the U S patent office has been bogged down by so many perpetual motion applications they have made it policy to outright reject such applications without a working model satisfactorily demonstrating it It is not a carnot cycle. It will NOT be able to pump heat, it's not a reversible cycle (it's not even a single cycle, it's a series of open-ended heat and pressure transformations). And using a heat-pump will also not make it a perpetual motion. Heat pump can be used as a kind of heat-transformer here, so if you have a lot of low temperature air (but higher than your ambient temp), you could use heat pump to gather energy from that air and present a higher-temperature air for my engine (losing some small amount of heat in the process, but heat pump will reuse heat wasted in it's own electric engine). It should achieve such efficiency with air heated to 150C and ambient temp of 20C. If you heat air so that it expands more than 2x, it will start to lose efficiency. BUT - this is all theoretical, I work on simulation that will confirm if it works. It might not, I might have made some big error in thinking how it works, but I searched for 15 years on some way this should not work. I contacted two physics professors specializing in thermodynamics and they couldn't find a way this won't work, both said "Yeah, but to tell more, we need prototype or simulation". A 68030 based computer - https://github.com/jeffsponaugle/roscoe It has been a super fun experience so far - I'm using CPLDs instead of an FPGA which makes the logic a bit more era period. I have a working system now with the math coprocessor, SRAM, DRAM, and other device support. I am just about ready to get the VGA card I designed produced so I can work on debugging the design. While this is fundamentally a system that ss less powerful than my apple watch, it is just fun to work on. Going back to very first principles debugging, building tools, and of course getting to exercise an old logic analyzer! Over the years, I've read countless books. I started documenting one idea that shaped my thinking from each of these books. This idea may or may not be the core theme of the book. Hope to document 100 ideas. Wish me luck. I'm building a small rural ISP and web hosting service, as a way to learn about low-level networking stuff. I've got an ASN + IP space, and am working out the details with a colo, local fiber provider, and some upstreams. Right now I'm configuring the hardware itself (server, router, switch, etc) and learning all the bits and bobs (Proxmox, BGP, OPNsense, IXPs, etc) All I can say is good luck. We spun up a co-op isp to take advantage of fiber grants for rural areas about a decade ago. Maybe it was because of the grants, but it was a fucking nightmare getting off the ground even though we had nearly 90% of the population in three counties on board for the co-op. The red tape and regulations (in our state at least) made it clear that government runs for urban and suburban interests and actively undermines rural needs. I'm talking government in bed with large providers who had exclusive rights to run "high-speed" Internet to our towns and farms, even though they had never and were never planning on anything above dsl for most people and cable for the ones in town. If I was more charismatic (and wasn't 1000% sure there were pictures of me doing drugs when I was in college), I would consider a run for state office, because it's a shit show for small towns here. And that's the story of a) when we got sued by a large provider that I hope goes out of business and burns to the ground, and b) the last time I volunteered on a large project and why I will never take the lead on anything bigger than the Lion's Club pancake breakfast now. Oof, thanks for sharing and the well wishes. I'm funding this myself, and my current approach (hopefully!) avoids most of the red tape. I'm leasing fiber from a local ISP for the colo <-> my home connection, and once I have myself as a successful "customer" of my own ISP, I'll start doing the last mile build out, which is where I expect the red tape to begin. But I haven't decided if I'll do fiber or wireless, and if I go wireless, I might be able to avoid pole agreements entirely by just working directly with my neighbors. The problem is that our area is pretty heavily wooded, so I'm not sure if I can place antennas high enough to cover a reasonable swatch of the area. > If I was more charismatic (and wasn't 1000% sure there were pictures of me doing drugs when I was in college), I would consider a run for state office, because it's a shit show for small towns here. Loads of politicians have come back from worse! Don't let that hold you back. Have been working on compgeo for a few months now and came up with a neat algo for our configurator at work! https://substack.com/@xlogiclabs/note/p-177713038?r=6s54sx&u... I've built a self-hosted reddit-like community platform in Go: https://baklab.app Users can create their own sub-communities, and within them, set up different categories and boards. Posts can be voted on, and board types can include regular posts, Q&A, or live chat. It's like a hybrid of Reddit and Discord but leans more towards a traditional web community. It also supports server-side rendering, making it SEO-friendly. This project is an extension of my previous Hacker News clone, dizkaz (https://news.ycombinator.com/item?id=43885998). I built a tool to generate a PDF for each row of a Google sheet. For example, you can generate 100 personalized PDFs (like certificates) for 100 students listed in a Google Sheet. Once you sign up and connect your Google sheet, it generates a template (using AI) based on your data, which you can edit in a Notion-like editor. You can then generate PDFs for your entire sheet or a for a range of rows. Some use cases I'm seeing: * Certificates for students or course completions * Monthly invoices for all your clients (https://sheetstopdf.com/use-cases/business/invoices) * Personalized reports with individual client data * Event tickets or conference badges * Contracts, offer letters, or any personalized documents * Really anything where you have rows of data that need to become individual PDFs Would love to hear what you think or if you have use cases I haven't thought of yet! I'm working on a K8S hosting solution that just gives the user a simple Kubernetes cluster. I (or we) handle the compute, (networked) storage and ingress hosting for you, and the cluster provision time should be within minutes. You just need to pay for a fixed monthly upfront cost rather than PAYG, giving small developers a good save of their money. In other words, this is similar to self hosting with K0S/K3S/OpenShift, except you don't have to own servers to begin with, in other words, it is a little similar to serverless K8S. Well, all you those you can actually do with a VPS today, heck why do I have to do it if EKS/GKE/LKE/OKE/DOKS exists? That's because it takes a lot of time to properly setup VPC/EBS/S3/EC2, you need to pay an insane amount of premium and overheads to those while an ordinary user just don't want to hassle too much. I want to undercut the big clouds by saving people's money and time. I have had enough of seeing a ludicrous EKS billing. I just want K8S to be the control panel of everything. Deploy, run and scale later, simple as that This resonates with my experience as a small startup dev. I wouldn't mind bringing my own servers for running my apps but for k8s I need at least 3 control nodes in each cluster and I need multiple clusters to cover different parts of the world. All those control planes are idling most of the time but cost money and effort to keep them alive. I'm sure those could be shared among dozens of users. Is this something you are going to support? Or I'll also have to rent the worker nodes from you? You rent the compute, storage and network from the worker clusters at a fixed monthly price as one budget package, just like how you buy VPSes back in the days (think EC2 Lightsail or Linode, except now you just have a K8S context). You can choose multiple geolocations, but I'm still looking for a successful lab simulation first. Right now I'm hosting my own test cluster under my bed so I can't show it. You don't have to manage CNI, CSI, Linux kernel, etcd. You just need Kubernetes app development knowledge and that's basically it. Now I'm still thinking about how to get live migration and failover working, so it is going to take a painful while...Kata Container doesn't support it out of the box but Cloud Hypervisor does Link? :) No link yet as I'm still just a solo dev, the (hobbish?) project is crawling very slowly, but I have the general architecture in mind. I need to get the frontend first. I tried to submit it as a startup project last year but the feedback isn't great, I want to have something polished first before making it public Hey HN! I'm building https://openfret.com/ - the all-in-one platform for guitarists that I wish existed when I started playing. OpenFret combines everything a guitarist needs in one place: smart gear inventory management, AI-powered practice sessions, real-time collaboration tools, and a vibrant community. Think of it as "GitHub for guitarists" meets comprehensive practice tool. Core features: 1) Smart Guitar Inventory: Track your collection with auto-filled specs from thousands of guitar models. Monitor woods, pickups, scale length, string changes, and discover patterns in your gear 2) AI Practice Sessions: Generate personalized guitar tabs and lessons based on your practice history, with VexFlow sheet music and integrated metronome 3) Session Mode: Fork and merge music tracks like code. Layer recordings, see version history, and collaborate with musicians worldwide 4) Practice Analytics: Persistent timers, song tracking (Last.fm integration), scale visualization, fretboard maps, and chord progressions 5) Built-in Tools: Guitar tuner with frequency control, Strudel integration for backing tracks, and musical helpers to break out of E minor habits Looking for: Feedback from guitarists/musicians on which features resonate most Link: https://openfret.com/ | Discord: https://discord.gg/G3Pur3PzZm Thank you! I am working on Rad [0], a programming language built specifically for CLI scripts, so you don't need to write Bash, and it offers CLI-tailored features which make it a better choice than Python. Lately I've mainly been working on stability and bug fixes. I've released some big features the past few months so I'm doing a big push on polish, before I again tackle some larger features that I'd like to implement. If CLI scripts is something you're interested in at all, give it a go! We have docs and a guide [1] for getting started, feedback very welcome :) [0] https://github.com/amterp/rad

We also offer Generative Engine Optimization + Competition monitoring. We are looking for an angel! Please reach out at hello@ceogenerator.com I have always wanted to learn Rust, but was too distracted to get started. So, I started working with Claude on building a postgres database replication application. I'm learning Postgres internals as well as how brittle database replication and subscription can really be. Although this is for Seren, you can replicate between any PG databases.
https://github.com/serenorg/postgres-seren-replicator Big learning: Claude Sonnet with Rust is massively productive. I'm impressed, but code bloat is a thing. 20 years and counting, working on https://next-episode.net (it's a TV/Movies tracking website and community). I've dedicated this week to some maintenance tasks that are long overdue (mainly modernization of the code and the database), kinda delaying the inevitable (which is to work on harder tasks in my todo - like adding features to the mobile apps). Untrusted code execution paired with AI to make explorative data analysis more simple [0]. I've spent a lot of time with web development in the past. This is breath of fresh air honestly. I recently have gotten into the "drag and drop" forms of programming like Node-RED and n8n. Obviously, anyone here who has read my posts knows I know how to write code, but having a bunch of built in connectors that are agnostic to each other with the Oauth and the like being somewhat plug and play allows me to iterate on some ideas a lot quicker. I installed an n8n instance on my server, and have become kind of addicted to making different Discord bots, and I'm having more fun with this than I thought I would. 95% of the stuff on there is basically drag and drop, and when I need more elaborate logic then I can easily drop into JavaScript. I am looking into writing new nodes for different services, and I keep having new ideas for different stuff I want to build. I created a free collection of 4,300+ real website designs (screenshots, fonts, colors, live links) https://fontofweb.com/u/fontofweb I was tired of inspiration sites like Dribbble full of polished mockups that aren't practical. Or awwward like sites that don't represent the mundanity of most websites. So, I spent a while building a tool that captures website design snippets. It's now a collection of 4,363 designs from 544 different domains. For every design, it extracts: The exact fonts used on the page (so far 561 unique font families I've found) The precise color palette A direct link to the live site You can check out the full free collection here:
https://fontofweb.com/u/fontofweb I recreated a little tool to simultaneously mount all the commits in a git repository as directories at the same time (but re-use the same inodes for the same content). The code is at https://github.com/matthiasgoergens/git-snap-fs The original was in Python and actually had a decent excuse for existing for a very specific problem at work a few years ago. The new version is in Rust and exists just for fun. This was also a small experiment in coding with OpenAI's codex. I wrote the Python original by hand---like a caveman. Codex was mostly ok at the actual code, especially once I told it to make `cargo clippy` happy, but it needed lots of help with the design. It kept insisting on extra complications and state. But perhaps I'm a bit unfair here, because I only figured out the nice and simple design after reflecting on the connection between Linux's fuse and git's design for a while when writing the original. So it's only fair that the computer would also need some help to see how to match them up nicely. Could you expand on what problem the tool was originally built to solve? We had a bunch of quants who were writing Python and Matlab code. Previously they just saved it in a (Windows) Shared Folder and it automatically showed up in the test cluster. No version control, no nothing. The test cluster had actually grown to a few thousand machines or so. Running Shared Folders over that was crazy, and no version control was crazy, too. In addition, they expected to be able to write output files next to the source files, and expected them to show up to be used by the other machines. We were trying to help them migrate to something saner. We could convince them to not intermix source code and output files, but as part of that bargain otherwise they wanted everything to look as similar as possible to before, but still support some git-goodness we have promised. To make matters worse, they had checked in some rather large files into their repository. Like Gigabytes, and lots of them. As before, we wanted to support running multiple processes at the same time, but this time on different versions. As a joke I suggested to 'just mount' the git repository directly (that we constantly pull to every computer in the cluster), but my boss thought it was a grand idea, thus the tool. An additional nicety: under the hood 'git stash' consists of two phases, the first phase make something like a commit from what you have lying around in your repo, the second phase cleans up what you have lying around. If you use libgit2 (or a similar library) you can use just the first phase to get something like a commit, and send that to the server to execute, while changing nothing on the quant's machine, and not forcing them to explicitly make a commit nor polluting their git history. One saner alternative would have been to just make a checkout for each run. But naively that would have taken more storage space than we had, thanks to those big files. Alternatively, we could have done some sharing for running the same version. But that would have involved some reference counting etc and cleaning up. So my suggestion was to 'just let the kernel caches handle it'. In the end, the prototype was useful to get the quants to get along with what we did. And luckily for our sanity, we could soon convince the quants to store those large files somewhere else, and not in the repository along with the code. That restored our sanity, and we could move to a more conventional scheme. The working life of the tool was blessedly short, but it played an important role in getting the quants to move along in their journey to using version control. Though even though on paper it might have looked like an abortive and wasted effort, in terms of business value it was very successful. I love the quants. They are very technical and very smart and effectively write software all day every day, but they don't see themselves as software engineers, and they aren't. I recreated it just for fun, because I like the connection between git and how filesystems work. You can really tell that Linus Torvalds, the original author and designer of git is an operating systems guy. I’m working on https://regularly.co/ - A website made for inquisitive minds to get their daily puzzle fix. Still very much a WIP (mainly working on tuning the difficulty of puzzles to make it enjoyable for most). That being said I really do enjoy the unique combination of puzzles when I do them each day. I’m looking for feedback so if you do take a look please do let me know your thoughts! Incredible. Thank you for sharing this, I love puzzles and like setting aside some time in the morning to do them. This will enhance that habit so much! A whole slew of daily puzzles, I'll let you know how it goes! I don't understand why I can't place two kings in "adjacent diagonal" position when they're in two different regions. Something like: ..k.. .k... Rules state they must be in different regions, row and column. No mention of diagonal or adjacency. Ah this rule is mentioned under “Kings cannot attack each other” (in the chess sense, two Kings cannot be diagonal from one another). I’ve updated the rule to make this a little clearer Maybe it wasn't there when you played, but rule 6 states kings cannot attack each other; chess kings can move one square in any direction. Without this rule the puzzle isn't solvable by logic, only trial and error. Working on a binary that will instrument every Java service running on Linux host machine with OpenTelemetry Java Agent. Kinda like this (https://github.com/open-telemetry/opentelemetry-injector) but with support of having multiple service name for different services. This includes tomcat, normal systemd services and also services running inside docker containers. EDIT: I am popping my cherry with this comment on HN. Been a lurker since past 2-3 years. Building https://typequicker.com I’ve always wanted a typing application that’s both more than typing random words and is data-focused so I built this. The more you type, the more the analytics system learns about your typing patterns and generates natural text to target those weakpoints (SmartPractice mode). There’s a lot of variety as well; you can practice typing code in any programming language, or type text of various topics, use custom text, etc). I’m working on a platform that makes it easy for people in West Africa to buy and sell cryptocurrencies (like USDT, USDC, ETH, BNB, POL, AVAX, etc.) directly with mobile money — the most popular payment method in the region. The goal is to bridge crypptocurrencies and local mobile wallets to make crypto useful in everyday life — not just for trading, but also for online payments. A few key features: Mobile money integration (MTN, Moov, Orange, etc.) Instant buy/sell of USDT, USDC, ETH, and other assets Crypto payment gateway — businesses can now accept stablecoin payments directly on their websites I’m currently focused on improving liquidity and expanding to more countries. Would love feedback from the community — especially around : - Liquidity and Marketing to find the first users. Happy to share more details or collaborate with anyone working on similar problems.

You dont need to know HTML, CSS, JS to build beautiful looking web app from Python notebook. I'm writing new backend to support ipywidgets, anywidgets in Mercury. https://github.com/mljar/mercury I wanted to see if I could use generative AI to build a whole business. Not just a digital product or an app — but the entire business from end to end: (Spoiler: I did manage it and launched in just 75 days from start to first order) - Three tier corporate structure with manager-managed LLCs and a private WY LLC as manager, complete with a knowledgebase-powered assistant that can write share registries, banking resolutions, meeting minutes, contribution contracts, loans and more - Supply chain management with proprietary lot tracking that tracks PO line items from production to delivery - Generated the base for all product images, helped write and research label design and text, wrote SEO titles and product descriptions - Used Claude Code to build the entire Shopify theme for the site, all collections, product pages, legal pages and a COA database to boot - Used Claude Code to build a custom Shopify app to integrate lot tracking into the shop so that when lots sell out the next lot is queued for sale and all lot-related metadata is synced to the product variant and displayed on the product page - used Claude Code to build a super analytics platform that combines the data from GA4, Shopify orders, and Meta business suite into a single feature store where I can wrangle the data to ask/answer any question I can dream of about audience segments, product popularity, what’s working or not, and get insights on what to do next If you care to check it out, the site is https://cosmicpeptides.com There are many language-learning apps, but almost none that focus on improving conversational Hindi for kids. Made this web app for my nephew, based in Singapore, after watching him struggle to find anyone to practice Hindi with outside of family calls (since most of his friends are Chinese). The idea is to have a 24x7 partner to speak with Hindi and make it fun. This can complement the formal Hindi classes that most kids of Indian diaspora parents take. My nephew started using this and is enjoying it! Link: https://www.hindispeakingtutor.in/ Looking to hear feedback from the community! Every time I talk acquaintances, friends and family members about finances I'm always shocked at how little people know about basic things like tax brackets, 401Ks, IRAs, ETFs, compounding interest, debt management and etc. So I decided to write a financial literacy/education book with a bit of humor and easily comprehensible language to distill some of these topics. I'm about 1 month into it and try to write a chapter a week. Really good idea, perhaps you can include some simple guidelines for long term investment as well. Looking forward for the publication of the book and buying it. Do you have a sample to share? Just some drafts in markdown but nothing I can share just yet. I'll be posting it here once I have the ebook done. I’m working a Garmin watch app to query all the rich data on the watch (health, physical, environmental, location sensors) from the watch + general AI assistant. Privacy focused using your own keys and Gemini. API calls direct from watch - no backend. https://untether.watch Recently launched an AI cafe ordering app https://www.hellocafe.ai using chat and voice. We wanted to make concept for an app using all local models for chat (llama 3.1 8B) and voice (whisper). Deployed using kubernetes and easily scalable not to mention fully open source! I'm working on Chatolia, an AI chatbot builder. The goal is to let anyone create task‑specific agents, train with their own data and an embed it into any site. Training is simple: paste text, upload files (PDF, DOCX, Markdown, CSV), or paste URLs and it will crawl/index them into a per‑agent knowledge base. I'd love to know what you think. I've been wanting to learn more embedded type projects, and I've been snacking too often so I've been building a box that will only open on the weekends. I got all the components, tested it on a breadboard, learned to solder and now I'm working on the 3d Print to enclose everything. I actually just did a test run to see if my current 3d design would fit my PICO board, and it fit, but not that secure yet. Im a developer but never worked this close to metal, so I've been so happy with how it's been going so far, making me real proud of myself. I'm building a Twitch streamer focused version of cameo. The first beta version is specifically for League of Legend streamers. https://demo.replays.lol/clipper (recording the demo video today). The idea is that a generic video message doesn't appeal to a fan of a video game streamer, instead what really would be cool would be watching them react to your best moment in a game. Our software removes all friction from the journey, the fan doesn't even need to record their own gameplay, we have bots set up that can load up someone else's gameplay just from their username, record their highlight for them, upload it to our platform, then the streamer just needs to come in, watch a ~60 sec clip, give a genuine reaction, press 'submit' and its all done. There's a few markets I'm trying to find product market fit in: ~1-2 minute coaching sessions, sports commentator style commentary over your clip from influencers, hyped up reactions from your favorite streamer, a community-focused segment on a stream of watching a compilation of your fan's best moments. We're ready to launch, just trying and struggling to find the first few people to sign up. I am working on a home-oriented solution (hardware box + software) for backups of the media files from phones.
The solution facilitates having a separate backup drive (stored in a closet) in addition to the primary data drive in the box. Reverse image search to match dirty XTC tablets to lab reports

Belgian food hygiene rating from official gov reports Porting my 2014 WebGL game (https://phoboslab.org/xibalba/) to the N64: https://x.com/phoboslab/status/1982883072292069641 How are you doing this? Do you have a blog going over the work or a Github page? Just curious, it's an interesting project. The WebGL game was build with my 2D game engine "Impact", which I previously ported to C[1]. The game has a 3d view, but logic still mostly works in 2 dimensions on a flat ground. The N64 version "just" needed a different rendering and sound backend. I’ve created a small command-line tool that generates a hash-based, human-readable list of git repositories and data folders. Its purpose is to capture the exact state of all projects and files in a single plain-text file. I built it because I work across multiple machines and often worry about which projects are on which computer or whether I’ve left any files in unique locations. Now I can diff the summaries between devices to see what’s out of sync, which repositories have uncommitted changes, and which folders have been modified. I avoid using cloud sync services, and most of my files are already in git anyway. I find that having clear visibility is enough, I just need to know what to commit, push, pull, or sync manually. I would be glad if it proves useful to someone besides me. Frustrated by the complexity and high overhead of most monitoring tools, I wrote Simon. It’s a single binary, dependency-free monitor in Rust that does it all: metrics, Docker, alerts, and file browsing. While maintaining a minimal footprint for embedded systems and other constrained hardware. I'm atm working on a couple of things, first the biz, a self-hosted home server OS that simplifies Docker management and provides a unified dashboard for running services at home. The goal is making self-hosting more accessible without sacrificing flexibility. And also building as a hobbie a procedural universe generation engine that simulates galaxies, solar systems and planets in real-time. Everything is generated from a seed with actual orbital physics, seasonal changes and so... Built with Python/Flask backend too but Three.js for 3D visualization and React instead of Vue3 as in the prior one. Think No Man's Sky vibes but as an explorable simulation engine really D: I have been working on https://easymiet.eu/
It is specific to the German rental market. Basically if you want to rent an appartment in Germany most landlords require you to fill out a non-standardized self-disclosure form. That can be annoying to the landlord because especially in larger cities you might have a couple of hundret applicants and it is also annoying to the possible renter since they have to fill out the same information for every apartment they apply for.
This is where easymiet comes in. As a landlord you can generate a viewing, shared it through QR or a link. Interested renters can apply using their profile. It also has a application approve and dismissal workflow automatically sending emails to the applicant.
My plan was to monitize it selling applicants the ability to add more info to their profile like a picture or relevant documents. However so far I haven't been able to generate much interest.
The tech stack is Next JS with BetterAuth, Drizzle and Postgres. It is hosted on a Hetzner VPS using Kamal ( wrote a blogpost about that if you are interested: https://markow.dev/blog/complex-next-js-app-kamal ) Quick feedback:
looks way too empty for me to look real. Could also just be a scam. Also: why would I as an applicant add more data for money? The landlord has the benefit, they should pay for that. > Wir sind nicht bereit oder verpflichtet, an Streitbeilegungsverfahren vor einer Verbraucherschlichtungsstelle teilzunehmen. Doesn't help haha. Maybe explain why? To be fair, the thread is called "What are you working on", so it's by definition work-in-progress. > Also: why would I as an applicant add more data for money? The landlord has the benefit, they should pay for that. In many hot rental markets (My experience mostly with Berlin), you are mostly not in a position to say "the landlord should pay that" and everyone is desperate to supply the best, most complete and most convincing documents even if it feels bad to fork over that much personal data to a random stranger on a platform. I'm getting back in to audio programming, starting off with Pd[1] and reading Miller Puckette's book[2]. I'm planning on writing some low-level C libraries afterwards, using The Audio Programming Book[3] as a guide [2] https://msp.ucsd.edu/techniques.htm [3] https://mitpress.mit.edu/9780262014465/the-audio-programming... An AI relationship coach built on integrative therapy principles: https://reynote.com Great stuff! how's the traction? Not good! I personally use it with my wife but getting people to try it online seems to be very tricky to do. Seems like there's a big trust hurdle to overcome. I'm working on fighting IBM's patent trolls.
IBM slapped the words 'AI Interpretability' on Gauss' 200 year old continued fractions and was awarded a patent. Now they can charge rent if they encounter a continued fraction library in the wild. It's bizarre Interesting. Do you have a link to the patent? Here it is: https://patents.justia.com/patent/20230401438 On Google Patents: https://patents.google.com/patent/US20230401438A1/en The authors simply implement a continued fraction library in Pytorch and call the backward() function on the resulting computation graph. That is, they chain linear neural network layers and use the reciprocal (not RELU ) as the primary non-linearity. The authors reinvent the wheel countless times: 1. They rename continued fractions and call them ‘ladders’.
2. They label basic division ‘The 1/z nonlinearity’.
3. Ultimately, they take the well-defined concept of Generalized Continued Fractions and call them CoFrNets and got a patent. IBM's lawyers can strip out all the buzzword garbage if they feel litigious and sue anyone whose written a continued fraction library.
Because, that's what the patent (without all the buzzwords) protects. Thanks for that. That is patently absurd. You sent me down a rabbit hole. In trying to track it down for myself I read a couple of others that I thought might be it, and was stunned by how obtuse these patents are. What sort of leverage does this stuff provide? You mentioned "charge rent". What does that look like? Honestly, I don't even know where to begin. It's insane IBM owns the patent to continued fractions. If you wrote a continued fraction class in Pytorch and called backwards (or even differentiated the power series) then you're infringing on their copyright. Tritium, the IDE for legal: https://tritium.legal/preview This week we're building out the UX around formatting and this month we're building a more robust set of integration tests and integrating with a large industry platform. I’ve been working on MemoryPlugin (https://www.memoryplugin.com), a tool that adds long term memory across AI tools Lately I’ve worked on a chat history based memory feature that can recall information from every conversation you’ve ever had with ChatGPT and Claude. It’s been particularly useful and also technically fun to implement. Speed has been very important as I do just in time summarisation and a multi stage RAG pipeline, and most LLMs have unacceptable performance. I ended up going with GPT-OSS on Groq due to its ultra low latency often completing full generations before Gemini or ChatGPT APIs return even the first token. The ability to recall details from conversations going back years makes tasks where I want personalised plans or feedback like 10x more useful, at times I get the AI to ingest tens of thousands of tokens of context to help me better. I am right now building a proactive coach on top of my AI work capture app. Concept is very simple: It takes a screenshot every few minutes and analyzes what you're working on. From there it identifies task blocks, and checks if it should start a chat based on your intentions (eg to tell you to move out of your rabbit hole, take a break, help with a task, ...) https://donethat.ai Passively processing screenshots is obviously pretty sensitive, it has an option to bring your own (local or remote) LLM, otherwise I process with gemini and never store any data. It's in beta right now so if you want to try it you have to enable "proactive chat" in settings. I also made a list of similar tools out there: https://donethat.ai/compare DIY grid-tied residential solar+inverter+battery. Trying to design the solar arrays' tilt mechanism now for lifting/lowering 5 panels at a time in winter (60-degree winter angle, 35-degree spring/summer/fall; ~24" difference). Thinking either two linear actuators, or a single hydraulic jack connected to multiple support beams. The weight isn't much, but I want a way to lift entire top edge at once to prevent twisting. Linear actuators are slightly more money and easier to build, but require power and weather-proofing. Jack is cheaper, but more complex to distribute force. Wondering if there's other options. (winch would require more robust/taller rear posts, seems more complex, might shade rear array) Tilting them vertical or nearly so is very useful if there could be any hail, that might be a good idea to support. What about compressed air? It might not be too hard to find a small brushless low power air pump that could drive pistons directly. You could mount the pump controller onto the back of the panels and use an accelerometer to measure angle, and run the pump until it's where you want it. You'd probably need to do some testing and make sure it couldn't get jammed, then build up pressure, then suddenly unstick and move unsafely. "Projects With Everyday Dave" has done quite a few tests, and may be worth a look: https://www.youtube.com/watch?v=I-Fz5T5c0OQ Best of luck =3 Thanks! And I've seen Dave's tests. Since I don't need a fixed angle, do need to maximize production (due to a limited sun horizon), and only have 10 panels, the best option is adjusting angle during winter. The N-S orientation is a really poor performer. (Notice that his test is 30-degree tilt vs N-S; 60-degree tilt will provide 20-25% more power than 30-degree at my latitude, without even considering bifacials w/snow. The only thing that would produce more is an active tracker, but I've got other things to do, and a December deadline...) I've been working on a sillier project lately. Green teeth! Lumina has made a probiotic strain that is able to, theoretically, prevent cavities. I don't care that much about, but I do think it is a neat strain that can likely colonize your mouth. I'm genetically engineering it to express sfGFP, which would theoretically make my teeth fluorescent green under black light. Would be fun at raves! Also, if I make out with anyone, you could theoretically see changes in microbiome composition just from green-ness. I do wonder how much microbiomes are shared while kissing: this would be an example of a way to directly measure that, instead of just measuring on proxy like much microbiome research I'm building a Meetup.com alternative, of sorts - https://www.radius.to/ It's intended to be a sort of social network focused on IRL groups/communities and finding others with the same interests in the same area, and just building local communities in general. It's currently still a part-time venture, but I'm planning a launch on HN soon to get input/gauge interest in the latest iteration.

Postbase Open source, drop-in replacement and self-hosted alternative for Firebase Using Node.js, Express.js, BetterAuth and PostgreSQL (JSONB) I'm working on Habitat. It's a free and open source, self-hosted platform for communities to discover and discuss their local area. The plan is for it to be federated.
I've recently solved an issue with cron jobs that was driving me mad for ages. I feel that I'm pretty much nearing a first tagged release, but I feel that I need to work on branding and messaging a bit before I do. I can't tell if I'm procrastinating that final push to something that makes it more official or not. - The idea: https://carlnewton.github.io/posts/location-based-social-net... - A build update and plan: https://carlnewton.github.io/posts/building-habitat/ - The repository: https://github.com/carlnewton/habitat - The project board: https://github.com/users/carlnewton/projects/2 Currently working on getting back into a fitness routine. I got into this habit of hacking on side projects in my very little spare time but I have realized taking care of my body will pay off far more than any project All the best - the best project to work on!
I recently tested a walking pad with a standing desk at my friends place - I was surprisingly productive being able to walk while using the computer. Will be investing in a standing desk and walking pad for my home office. I'm resurrecting peer-to-peer Matrix (https://arewep2pyet.com) thanks to the Dutch government, who started funding it in October. The main question is which P2P overlay network to use, if any: the prior incarnation used Pinecone (a variant of Yggdrasil), whereas this time we're pondering keeping it simpler and more scalable and using Matrix itself as the backbone to connect together smallish local P2P meshes - so by default you try to route via Matrix, but failing that you look on your LAN or BLE to see if you can talk directly to whoever you're addressing. Time will tell if this works :) If you are open to suggestions, libp2p has a good amount of sdks for several languages and you can integrate kademlia for peer discovery We are open to suggestions :) And the very first generation of P2P Matrix was indeed built on libp2p (and Protocol Labs led Element's Series B). However, the thought experiment here is whether we can get away without a full global P2P overlay at all in the interests of keeping it simple & stupid. We might well end up back at libp2p tho! Edit: another option on our todo list to look into more is Iroh (https://github.com/n0-computer/iroh) [flagged] We've banned this account for repeatedly breaking the site guidelines and ignoring our requests to stop.

Working on a phone app that streamlines household management for unmotivated losers (like me) so that they stop wasting money (wasted food) and time (procrastination) Working on an app that helps me (and other people) do household management on autopilot. It helps me manage things, food, expiration dates, shopping, chores, and I get notified periodically to review my lists. I waste way less food and I actually do my chores instead of procrastinating. https://okthings.app It looks like you have to do a lot of data entry when you buy things, no? Yes.
How i tried to solve it: you have a shopping list where you can add things on the fly.
These things will need to be categorized (food, household supplies etc) at a later date, which is when the review is due for the "Uncategorized" category. Generally, i tend to buy the same things, so the "big" data entry job happens only once. I've spent several years since Covid times solo-developing an ad-free website with 50+ solitaire/puzzle games. I've gathered some feedback from users from HN already and now trying to fix things. I'm looking to genuinely improve the experience so would be incredibly grateful for any feedback. I'm also wondering what it lacks – any particular games or modes? I was a YC founder in 2006 and now work as a data scientist full-time, but on the side I also do Christian apologetics, helping fellow engineers/scientists/mathematicians seek answers to life's deepest questions. Some cool articles for the HN crowd: - [published several days ago] Medical miracles in Lourdes, France recognized by the Catholic Church 2018-2025: https://www.saintbeluga.org/our-lady-of-lourdes-immaculate-c... - My interview of Evan O'Dorney, a three-time Putnam Fellow and two-time IMO gold medalist, who converted to Catholic Christianity: https://www.saintbeluga.org/veritas-part-i-conversion-of-a-p... - In-depth scientific overview of Eucharistic miracles: https://www.saintbeluga.org/eucharistic-miracles-god-under-t... - Conversion testimony by Harvard astronomy professor Karin Oberg: https://www.saintbeluga.org/veritas-part-ii-conversions-at-h... If we collect DNA from eucharistic miracles can we clone Jesus? I know you're being facetious, but DNA tests in the Tixtla case said the DNA was too degraded to analyze. Small webapp that allows musicians to add PDFs locally and offline, arrange them, then download for use on an e-reader during performances. Built for a classical musician friend who uses really old Android devices, also my first almost entirely 'vibe-coded' app. I’m working on a platform to run a friendly competition in “who builds the best reasoning AI Agent”. Each participating team (got 300 signups so far) will get a set of text tasks and a set of simulated APIs to solve them. For instance the task (a typical chatbot task) could say something like: “Schedule 30m knowledge exchange next week between the most experienced Python expert in the company and 3-5 people that are most interested in learning it “ AI agent will have to solve through this by using a set of simulated APIs and playing a bit of calendar Tetris (in this case - Calendar API, Email API, SkillWill API). Since API instances are simulated and isolated (per team per task), it becomes fairly easy to automatically check correctness of each solution and rank different agents in a global leaderboard. Code of agents stays external, but participants fill and submit brief questionnaires about their architectures. By benchmarking different agentic implementations on the same tasks - we get to see patterns in performance, accuracy and costs of various architectures. Codebase of the platform is written mostly in golang (to support thousands of concurrent simulations). I’m using coding agents (Claude Code and Codex) for exploration and easy coding tasks, but the core has still to be handcrafted. Ooooh, neat, I had a similar idea, like an AI olympics that could be live streamed where they have to do several multi-stepped tasks https://github.com/superegodev/superego An open-source, local database which collects all your personal data, hooks it to an LLM (BYO), and gives you an assistant that can answer any question about your life. It also allows you to vibe-code (or just code) small apps on top of your data (e.g., your custom dashboard for your expenses). I have a short demo here: https://www.youtube.com/watch?v=gqAyvENDjSA Working on a little project to make Spotify recommendations better. You get to choose the genres you're interested in, and it creates playlists from the music in your library. They get updated every day - think a better version of the Daily Mixes. You can add some advanced filters as well, if you really want to customise what music you'll get. Does this deal with, what I call the "Armin Problem?" I typically listen to EDM and there is an extremely popular DJ named Armin van Buuren, and he has other aliases (which exacerbates the issue). His sets end up directly on music platforms, and he pulls in a ton of EDM sub-genres (which makes him a great DJ!). Any recommendation algorithm that visits one of his aliases is doomed to be connected to every other sub-genre, so I might be listening to progressive trance, and be in the mood for that, and end up on deep house (as an extreme example). Within EDM, genres can be as different as blues is to metal. Not directly, no. I still rely on the data that Spotify gives me that relates to artists' information; and it's not great a lot of the time. E.g. there are obvious cases where artists belong to genres that they should not belong to. I do have some ideas for improvement, but they are still WIP. What it allows you to do, though, is create your playlists with extended filters. E.g. you can select genres, and at the same time exclude genres - that helps with the "cross-contamination". You also get a view of all the artists that match your selections and you can add exclusions for them as well. It is a bit of manual work, but it works pretty good for me personally. I wanted to visualize all my walks and runs on a single map. I built a native iOS app that fetches Apple Health and Strava workouts and visualizes them. Privacy was a major factor in building the app, so all the data stays on the device. Next version will have a time-lapse video option. Any feedback welcome. Strava and Apple Health integration is cool! What was your main differentiator to build it vs something like https://fogofworld.app? Thanks. I wanted to focus on performance (native app), simplicity, and privacy. Very cool, downloaded and using it right now. Do you have any future plans with this? I'm working on a feature to create fun timelapse videos of all the routes on the map. It should be released next week. I'm open to any feedback. It is a recipe app but better, and way more technically capable than anything out there. The goal is to make the best recipe app ever made. With bulletproof easy to follow recipes and smart features to make cooking simple. Everyone deserves good food at home, but good food is complicated and time consuming. An experienced cook can make good food quickly, cheaply and make it look easy. The idea is that Kastanj will have the knowledge you don’t so you can cook like a pro without having to spend years learning everything. Backstory:
I have a note where I write down practical problems I experience in life. I noticed over time that the amount of notes related to food and cooking was growing faster than anything else. I then began searching for a solution. I tried over 50 recipe apps, always the premium version if possible. There are some good apps out there but even the best ones only solved something like 50% of my issues. After enough frustration and search I just decided to start working on my own app. That was 4 years ago...
It turns out that solving some of these problems where technically complicated to do, so now I understand why no other app could solve my problems. None the less, after 4 years of work, starting over from scratch 5 times, I have now landed on a solution that technically solves all my problems. Going forward:
Now I am working on filling the app with data and make it easy to use for normal humans. I am on purpose limiting myself to only perfecting the core functionality of what a recipe should be. I intend to launch sometime in 2026. The UI will be small and limited at first, but it is perfect for my needs. Therefore I hope it will also be perfect for someone else. Over time I will enable more advanced functionality and build it out based on user feedback. I know the backend can support 100% of my needs, but I don’t want to make it bloated. Therefore the UI is on purpose focused on only the most important things and then we will build it out with time, together with the recipe creators and end users. https://aykev.dev/webgpu-waveform/ https://github.com/mrkev/webgpu-waveform Made some updates to this open-source library I wrote to render audio waveforms using the GPU on the browser (WebGPU). Example on the site. Works without enabling flags on Chromium browsers. There's an example to scrub and zoom in real time on some audio. Feedback welcome! https://github.com/DeutscheKI/jetbrains-mini-agent Fully offline LLM coding agent plug-in for JetBrains IDEs. Use with Qwen3-Coder-30B-A3B-Instruct-UD-Q4_K_XL.gguf on an RTX 3090 or up. The source code is pretty short to make sure it can be audited, if needed. I am building https://arabicworksheet.com, AI powered Saudi Arabic learning app for expats who work and live in saudi arabia. 100% FREE. It generates printable worksheets based on your level, dialect and topics. I am also building an app for kids to make their arabic learning fun, rewarding and enjoyable. Do try and share your feedback. TIA Steam game. Exposure to unity has got me thinking hard about its non-gaming applications. The stability of presentation between device targets is incredible. Being able to integrate literally anything you want in native 3d world space feels like a natural next step once you get bored of the DOM. Currently building a suite of media inspection and encoding tools for video engineers: https://video-commander.com. Still very much a work in progress, but expecting to release a first version by end of year. Built on Tauri, in case anyone is curious. I've created various open-source and commercial tools in the multimedia space over the last 10+ years and wanted to put it all together into something more premium. I am working on https://embedhub.com I am building better dev tools for firmware and PCB developers. For example, we have GitHub Action workflows that allow you to push builds to the connected EmbedHub project. Your EmbedHub project has fine grained release management - so for example only the git tagged releases will be shared with the customer, but the testing/QA team will get access to builds from regular commits on branches as well. I am also building a physical device (called HAL) similar to the now discontinued EtcherPro[1] - which will connect to your EmbedHub account and have access to your releases. This will let you offload tasks like long term testing, mass flashing and provisioning of devices, and more. I’m working on an AI-powered page optimizer for SaaS & eCom sites: https://peakagent.ai No complex setup – drop in a script, keep your existing stack Auto-generates variants for hero, copy, CTAs, and social proof Continuously tests and routes traffic to the best-performing variants Optimized for key pages (pricing, signup, product, checkout) Reports focused on conversion & revenue lift, not just clicks Would love feedback, tear-downs, or ideas for must-have features before you’d trust this on your main pages. PS: Deeper ad→page→revenue attribution + personalization by segment coming soon. We are building https://desplega.ai which is a QA agent that help teams ship fast without compromising quality. We focus on making it as fast as possible, integrated into CI, MCP for local dev, and support both an autonomous (we call it discovery) and guided test creation approach. We believe that in the era of vibe-coding, quality is key, as we are lazer focus on building a solution that scales with your product, and removes the burden of QA from your team. Technically, we built an in-house engine that is in charge of generating the tests, that speeds up and gets better the more you use it. Working on https://libredesk.io/ It's a modern, open source, self-hosted customer support desk. hosting a month-long residency for indie hackers in Da Nang, Vietnam! we invited 10 of the best indie devs from around the world to live & build alongside us for a month at a beautiful villa. for free. (we have sponsors like OpenRouter, Cognition, n8n, and CodeRabbit!) we're 10 days into our first batch – would love feedback :) I'm building GhanaHousePlanner https://ghanahouseplanner.com/, a web platform to help people in Ghana/diaspora plan, estimate and manage house construction projects. It is free for individuals and only project management and using the floor planner ai agent needs subscription. Current features include: - Live material price list updated monthly (based on prices at local shops) - Conceptual 2D/3D floor plan generation following Ghana Building Standards (development in several phases using procedural floor plan generation) - Construction management dashboard to track project stages and conversations between project manager, mason, carpenter, etc. - Printable material cost breakdown TODO: A contact listing for local construction services I would love to have feedback, thanks. Working on adding MPD [1] client mode to my music player: https://github.com/olegantonyan/mpz Currently it works as standalone player. Addition of MPD client mode opens possibility to play music on a separate device while keeping the UX of the music player that I like. I've been building a Decentralized Database built on top of syncing CRDTs, and recently got it to a point I can demo. It's definitely in a "proof-of-concept" stage though, known security holes and all. I've been focused on building out the featureset and keeping everything unstable instead of trying to finalize each piece as I build it. It's the opposite of how I normally build things but I think it's been working pretty well for this. I've written about it a few times, most recently "Using CRDTs + Sync as a Database" - https://jackson.dev/post/crdts_as_database/ Today I'm hacking on automate-terminal, a command line program and Python library that abstracts the various terminal emulator automations (iTerm2, WezTerm, Kitty, tmux) into a single API. Mostly made for use by other tools. https://github.com/irskep/automate-terminal sounds interesting. what was your first scenario when you thought, “Baam! I need to automate this, and I'm going to do it right now!” ? Music player that can organize album collections from different services like Spotify, Apple Music and Bandcamp, Discogs, and show detailed and high quality information that can be searched and filtered. Rates your sleep, tracks sleep debt, and tracks how workout timing, coffee time, AC temperature, etc influence your sleep. 2.0 is in review - adds support for recovery (based on sleep HRV, HR), and strain. a demo video here https://x.com/rohitshindein/status/1985643097439813831 I recently became unemployed so I am building a tracker for all my job applications what stage I am at in each process that kinda thing It’s no where near done But as always I am also building https://retro-board.it for doing retros and sprint poker And https://flags.gg for feature flags with quite a lot of agents (rust, go, react, and others) Wondering what people are using AI for and if there are public/shareable/or leaked chats out there from all platforms either chatgpt, gemini, grok, claude, perplexity etc. So I am building this https://www.leaklake.com , where you can search your name, brand, and basically any keyword. You can also set an Alert because crawling and starping is running 24/7. Any feedback welcome. I'm working on a free replacement to the NY Times daily mini crossword after they started charging for it and I didn't want to pay. https://www.jepeto-mini.com/ (DNS may still be propagating). A fun project with lots of challenges finding word lists, refining them, using AI for clue generation, etc. I played it, and it was fun. Some feedback (I'm on mobile) is that it needs UX improvement. At first I wasn't sure what I had to do, it simply throws you into the game, and it's easy to get confused with the numbers around it, because usually if there are numbers, there is going to be somewhere (usually at the bottom) the numbers and the clue for each of them. It took me a bit to find how to get the clues from the vertical words (double tapping). The onscreen keyboard isn't very responsive in the sense that I had to tap several times the backspace to delete a letter. It doesn't allow to play again :( Last week I launched https://qcready.com which measures your Post-Quantum Cryptography readiness. - no sign up, free - checks PQC usage among all the servers in a domain - uses Certificate Transparency to find all your TLS endpoints - tells you how far you are from PQC readiness Neat. How does it calculate the readiness? It's the percentage of TLS servers that serve PQ cryptography among all servers in the domain that serve TLS I've been working on real estate prices map visualization for a couple of years as a side job. There's After one of my cyber security research caught some attention in media, am now working on - Open Source Vacuum Robot firmware we are working on Aye Chat: an AI development tool for the terminal. It will make changes directly and let you revert changes through our snapshot feature, all while you can stay in the terminal to execute your favorite (terminal) editor and what not. If allows the use of different models, no need to sign-up at the moment and at no cost. We released our beta just last week. We were getting annoyed by all the additional confirmation questions by other AI assistants, and having to switch between consoles to use a editor and/or revert changes. Check out our repo at: https://github.com/acrotron/aye-chat or just install it: # pip install ayechat Building https://github.com/openrundev/openrun, a platform for declarative deployment of web apps. OpenRun runs as a web server, which does GitOps driven app deployments. You can currently deploy apps on a standalone machine, on top of Docker/Podman. Working on adding support for deploying on top of Kubernetes. On Kubernetes, OpenRun will replace your build jobs (Jenkins/Actions etc), CD (ArgoCD etc) and IDP (Backstage etc). The same declarative config which works on a standalone machine will work on Kubernetes, with no YAML to maintain. Working on Astrology App - https://bestkundli.com There have been a few astrology apps, but all require you to connect with an astrologer or a pandit. This market has been in past and today, a market of exploitation for the innocent. So, I built this app to let people read their birth chart with detailed analysis, without any such thugs. There are a few very talented experts, but they are either very expensive or difficult to find. So, it came out of necessity. I would love your feedback on trying it out and letting me know your thoughts. Cheers A small OpenGL tutorial for Rust. Focus on understanding the OpenGL-API and interfacing with it directly, with a few as possible helper libraries. Some of the chapters I'm currently working on can be found in the preview (https://preview.opengl.zgtm.eu/, ipv6 only). Working on a curated Hacker News x AI newsletter. There’s so much nuance in HN threads that often gets missed elsewhere, so I decided to put start this newsletter. Initially started as an experiment for 10 issues to see ig it gets traction, 6 issues in it’s at 68 subs and probably will continue for unlimited time period. Link to the latest issue: https://eomail4.com/web-version?p=01b6f55e-bb2d-11f0-bcb3-f3... Link to subsscribe: https://hnxai.eo.page/9h7q4 A kernel extension-less sshfs for macOS. I tried using FSKit and got halfway before I felt too constrained by the extension security model (must be app sandboxed, must be approved by the user in system settings). Now it’s just a standalone command line binary that doesn’t require any special permissions since it proxies NFS to SFTP. Everything “just works” and performance is reasonable Interesting... the way I workaround'd non-macos-native-sshfs is by using docker and mounting a local folder, do you plan on publishing your tool? I’ve been working on ScratchTJ, a DIY digital turntable built with a Raspberry Pi and Arduino Nano. It’s based on the open-source SC1000 code, but with some hardware changes and tweaks to make it easier to build and customize. It runs on a Raspberry Pi 2 with an AudioInjector sound card, a small LCD screen, a rotary encoder, and even an old hard-drive platter as the “deck.” The goal is to make a simple, open, and affordable way to experiment with scratching and mixing — no fancy gear required. It’s still in progress, but it works pretty well and has been a fun way to explore DIY DJ tech and embedded audio. Im a simple man Made a small web app for my local game store for playing magic the gathering where you can analyze your commander decks: https://brackcheck.com/ ABISan. Think of it like UBSan, but for assembly. It's a custom assembler built on top of the LLVM assembler (llvm-mc) that emits instrumentation code to catch ABI violations at runtime. Stuff like clobbering nonvolatile registers, misaligning the stack pointer, misusing the redzone, assuming volatile registers don't change across a function call, etc. Hoping to finish up basic x86_64 support within the next few days. I can now reliably assemble and run unoptimized gcc output without hitting false positives, but I still have to iron out some false positives triggered by OpenSSL's handwritten assembly routines. TODO items for the near future include porting the runtime support library into a kernel module so I can instrument Linux, and beginning ports other architectures (ideally something semi-obscure like POWER or RISC-V). I also need to figure out how to support dynamic linking, because the tool currently needs static linking to access its thread-local variables. https://github.com/kenballus/llvm-project/tree/abisan/llvm/t... I've created an AI-assisted writing platform, that doesn't generate text, but instead lends focus to human creativity, and have AI assist you instead of trying to replace you. You create a writing style via existing text examples, blog posts or URLs, and Arcitext extracts a "writing fingerprint" which it benchmarks new text against. There's a solid Markdown Editor with tools such as Tone Fit, Rewrite suggestions and Fact Check, which helps you when you need it. Kind of like having a writing coach and content strategist on speed dial. My friends and I have been hacking on http://dateit.com for a while.
It's an event planning app (works best on iOS and android, but there is a web app) with lots of fun features: It's grown into something much more than our original idea. Most of the features are free and we have a fair pricing model that doesn't nickel-and-dime you like many of the competing apps do. Would love your feedback! I made an LLM-assisted DnD character sheet tracker! It's up here: And the repo is here: https://github.com/igor47/csheet If you play DnD, I would love feedback! Feel free to leave it as GitHub issues or discussion. If you don't play DnD, you might still find the repo interesting. It's hono on bun, I render jsx server side and client side is all htmx. I use vercel's ai toolkit for the LLM interactions, which are super fun and work really well. I think this is a great use for AI actually. I've structured the code so the same services can be called either by the user via forms and routes, or via LLM tool use, so for every action in the code you can do it via either LLM or "manually". The LLM usage is fun and interesting. What model are you using, and how much customization are you doing to integrate with the app and maintain character? I suggest adding an export function to make the characters more portable. Maybe export to PDF as well as JSON. Amazing! I was planning on making a tool just like this, will take yours for a spin! I made a HN-like discussion forum for (meta)science. Most (meta)science discussion is either fragmented on Twitter/Bsky, or a bit too formal. I thought a centralised place for deeper, casual discussions might be helpful, so I'm testing that theory. Launched a few days ago, so it might have some rough edges. I'm considering making it user-invite-only soon, but for now it's fully open for signup. I'll also move it to its own domain once I think of a better name. For the past 2 months I have been doing a heavy deep dive into image generation and image generation editing capabilities. This then had me discover that you can generate storyboards for short stories, and automate the creation of these as videos with video generation models. This is a topic that interests me heavily, and as such I am now building my own workflows around that. I am documenting the entire journey here: https://edwin.genego.io/blog/lpa-studio https://edwin.genego.io/blog/ai-branding It's not something I am looking to commercialize, but I actually did drop out of film school (with semesters in creative storytelling) to pursue software 15 years ago. And I feel like this will open up a whole new way of visual storytelling as well as personal and product branding. I have gotten quite some emails about it, from interesting people in different industries, as some more strongly worded (not so nice) emails from someone in the VFX industry since I started. Its by far one of the most interesting tangents I have ever went on. For my work I've developed a web-based Monte Carlo simulator with a visual, node-based editor for building supply chain models. Last week, I started making it available for everyone. You can have a look at https://simcarlo.com. The tool allows you to see the full spectrum of potential outcomes instead of just a single guess. I'm building a coding agent, named VT Code [0]. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter. Supports multiple LLM providers with automatic failover and efficient context management. Support OpenAI, Anthropic, Google Gemini, xAI, DeepSeek, OpenRouter, Z.AI, Moonshot AI, MiniMax, and Ollama (local & Cloud). Agent Client Protocol and Model Context Protocol fully support. VT Code supports a rich set of configuration options, with preferences stored in vtcode.toml. Has both Visual Studio Code and Open VSX extensions so that you can install in VS Code or Cursor, Windsurf, Eclipse. I've been building it for several months now and enjoy the learning process, I also wrote a blog post and learnt a ton about terminal, ANSI processing. The learning has been immense for me, I now have working knowledge of ANSI escape codes, grapheme clusters, terminal emulators, Unicode normalization, VT protocols, PTY sessions, and filesystem operations, all the low-level details I would have never think about until I were implementing them.

(For reference, this service is designed for Korean users — I’m Korean myself.) I'm working on a (hopefully) better version of Spelltable to play Magic: The Gathering with my friends: https://cardcast.gg. I think I got all of the important bits in place, now just working on improving the quality of life experience and bug hunting. Looking at an ancient game called Trias/Ternii Lapilli and learning/using maths to figure out if it can be solved https://tom-dickson.com/blog/trias-game-investigation/ It’s similar to tic-tac-toe but slightly different of course. Found it a great opportunity to learn about new areas of maths. Trying to figure out where to go next with it. Meta question: Is there a cadence for these threads? I had in mind to "be prepared" to post in November's with what I'm working on, but I expected it to come around on the 15th (mid-month). What I'm working on: - skuilder - (skill builder) - https://github.com/patched-network/vue-skuilder - an AGPL framework / toolkit for SRS++ based interactive tutoring systems - https://letterspractice.com - a low cost, hopefully high quality early literacy acquisition app, targeting ages 3-5. - https://flutor.app - an app to learn the flute (The proprietary apps are built with the toolkit). I've struggled to pitch or articulate the vision here, but my latest pithy attempt is: scaling self-actualization by mechanizing the nested loops described by Anders Ericson's 'deliberate practice'
- Inner loop: individual learners maximize their skill uptake velocity and performance peak by adhering to domain specific best practices
- Outer loop: domain specific best practices get refined according to innovation or serendipitous discoveries from the inner loop (eg, someone is observed to beat out prior best practices) As mentioned, I'm flat-foot posting here, so the pages aren't all prepped. https://flutor.app/dbg and https://letterspractice.com/dbg show some of the innards. Not linked, but I'm especially fond of https://letterspractice.com/dbg/juggling - the premise here that as child practices the letters, the letters exemplify the principles of effective practice in alliterative skill domains (juggling Js, batting Bs, flossing Fs (it's hard ok?)) Working on a free alternative to Masterclass - compiled from YouTube clips! Currently have two binge-able mini courses on How to Start a Startup (could be relevant to folks in here) Here it is: https://opencademy.com/ A Civil 3D plugin (Genabler) that will include all the network catalogs and collate the Civil 3D styles for civil engineers to use.
There are some out-of-the-box catalogs and styles shipped with the default installation, but they are quite limited and fairly well hidden—which is not surprising, given that Civil 3D is a huge beast. As a result, they are not commonly used. When people think about Civil 3D, they often assume it requires BIM modelers (in a sense, just glorified drafters) to create all the necessary catalogs and styles, and to assist with their use. My Civil 3D plugin will: 1. Make standard, market-compliant catalogs and polished styles available to engineers at large. Think of it as the WordPress theme provider equivalent. 2. Make the entire process easy and painless through the plugin, with prominent buttons for quick access. If the plugin is done well, there will be less need for BIM modelers, since for a fee, engineers could simply purchase catalogs and styles that are so easy to use they require no technical training. As a side benefit, I also get to explore how LLMs can help me write code. It has been a while since I last updated my AI usage policy [0], and I look forward to revisiting it. I'm working on a performance review (PR) management platform that doesn't require a steep cost and deep integration into HRMS platforms. It's a need I have for myself and the teams I run – It offers direct PR's, 360º reviews, recording of wins and lessons (something often overlooked), and aims to be a platform for team and individualised growth, that is accessible to small and large businesses alike. I've been working on a little game for my daughter to help her learn the movement of chess pieces. https://www.minichessgames.com It's currently just a "maze" type game where you have to get to a goal square in the minimum number of moves (there are rocks placed on the board to act as obstacles) I'm in the process of making some very simple games like battling knights where they leave poo and you try to trap your opponent. Fun making it even if it's just the two of us who'll enjoy it :). Partly I wanted her to learn that you can create for the internet not just consume... Building a language learning tool again[1]. I have found for myself that there is a lack of vocabulary learning apps that have good search functions. When I make a search function, I want it to be able to find all subsets of words, that I could think of. Instead what many search functions only allow you to do is, to first find one set of words, and then in a new separate search find another set of words. Currently working on that search function. Also what I find annoying in spaced repetition learning apps I have seen so far is, that they will ask you very simple words over and over again, just because you didn't see them in a while. But I really don't need to learn those words over and over again, because I just know them. Another annoying thing is, that in some apps you cannot see your learning progress. How many percent you already learned. Or that you cannot specify how difficult a word is to learn. Or how relevant it is. All this metadata, that could be good for learners to be able to search through, when searching for the subset of words they want to learn next. Oh, and of course tags ... With tags one can add all kinds of attributes to words. Maybe I am only looking for nouns or verbs. Maybe I am only interested in words that have something to do with family. There is still a lot to do, but it is taking shape nicely. The app is written in Python and tkinter. It is very simple to use in most aspects, and I really don't care much about the looks. I actually find them refreshingly simple and functional. Not this "everything flat" kind of epidemic in UI, and widgets still give feedback when using them. Not web based with the typical nodejs or npm overhead and tens or hundreds of dependencies. Nope, keeping it very minimal so far. I also have another idea, that might give it a modern touch, but that might also introduce overhead and probably should be an optional setup or feature: Give users tools to let LLMs generate example usages of words, if they want to do so. Of course that would have to be a local LLM I don't want to get into users having to sign up somewhere and get API keys and all that. I am also not planning to make a mobile app. Maybe later I can create an API, so that one could build a web frontend, if one chooses to do so. But first I want to build this app and the functionality behind it. Working on some tailored to my needs tax reporting software. I submit claims to my workplace in batches under a number of different categories. Using this as an excuse to get better at some bits of SQL, leaning Textual as well, which I'm hoping to use in other things. Other than that I'm cooking a few IRC bots that I swap to when the other code becomes a bit too boring Problem: I collect a lot of music I come across in playlists on Youtube/YT music/Bandcamp, but tracks often disappear for various reasons. Working on: Offline Youtube playlist download manager. It uses YT-DLP to get all my music and then enriches artist/track metadata using MusicBrainz, AcoustID, Discogs, LastFM, Spotify. Runs as an offline webapp so I can browse and play music locally. Might play around with recommendations for fun later. Happy to publish the repo if anyone else would find this useful. I have been tinkering on a little price drop alert scraper written in Python. It's run as a cron job, and every day it checks the prices of a list of urls (my clothing staples from various outdoor retailers, mostly) and sends me an email with any products that have gone on sale. I've been running it for over a year, but now I have fixed it up and made a little landing page to see if there's interest for a stupid-simple price watch service like this (no need to install an extension or create an account): SPLADE-easy: https://github.com/dleemiller/splade-easy I wanted a simple retrieval index to use splade sparse vectors. This just encodes and serializes documents into flatbuffers and appends them into shards. Retrieval is just parallel flat scan, optionally with reranking. The idea is just a simple, portable index for smaller data sizes. I’m targeting high quality hybrid retrieval, for local search, RAG or deep research scenarios. SPLADE is a really nice “in-between” for semantic and lexical search. There’s bigger and better indexes out there like Faiss or Anserini, but I just kinda wanted something basic. I was testing it on 120k docs in a simple cli the other day and it’s still as good as any web search experience (in terms of latency) — so I think it’ll be useful. We’re still trying to clean up the API and do a thorough once over, so I’m not sure I’d recommend trying it yet. Hopefully soon. The Daily Baffle, a site with all sorts of daily puzzles including one clued daily by NYT-published constructors. Can check it out at https://dailybaffle.com I'm still working on growing the audience. App coming soon! I just launched a 10-Bit Video Thumbnail Provider for Windows. Windows does not natively support rendering thumbnails for 10-bit videos, which are commonly produced by cameras like the Sony A7IV. When I started working on a short film the video clips were piling up on my hard drive. Opening them one by one to find what I was looking for was tedious. I could not find a reputable solution to this problem, so I started a company and built one. I went through the process of EV Certification to have the installer and executable code signed. I hope to be in the Microsoft Store soon. I'm also building other utilities with similar purpose. Built a web interface for Magic: the Gathering draft pick advice, trained on top player data. Website: https://statisticaldrafting.com Turns out to be a small niche, but I enjoy it! Mockaton. An HTTP Mock Server with a dashboard UI for changing mock variants on the fly. For example, for testing retries. https://fooqux.com/ - an experimental tech article aggregator. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website. The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experimental features like annotations, questions, etc. I hope this service might be useful to others as well. You can sign up with github account to submit your articles as well. I would appreciate any feedback. I'm working on boiling the ocean - we're building a new CRM to compete with some of the big players. I tried very hard to avoid doing this, but I've helped enough business owner friends set up CRMs to realize there's MUCH to be desired. My goal is to create a CRM that people rave about - something that is very rare. Pretty much everyone I help views CRMs as a necessary evil. Our bold challenge is - can we make a CRM that is delightful to use? Of course we have to slap "AI" on it in this market, but we plan on adding AI features that are actually thoughtful and not just a glorified chatbot. Sounds interesting! As someone who works in Revenue Operations the CRM space is ripe for disruption, especially around using CRM data to help sales teams explore the data. I vibecoded a POC of what something I think would work (around the latter part around exploring the data). Need to complete it and start testing it. Thanks! I totally agree. It starts with getting the basics right. I think this is where most CRMs get it wrong - getting users to correctly enter and maintain clean data is a challenge. We're trying to build smarter schemas for contacts, quotes, sales, etc. but we're also making a really intuitive UI for easily updating information. Further still, we're trying to automatically fill in data for the customer. Many fields can be automatically inferred based on the context of a deal. Once we get this right, I think the next step is exactly what you said, building really good tools to explore the data. Making it easy for non-technical users to run machine learning on their data to make business decisions or see cool visualizations. We realize that so many of our customers want to know this stuff and have no way of getting at it! We've got a lot of ideas for both visualizing and analyzing the data. I think there's a ton of potential for cool things here. Heatmaps, spiderwebs, interactive charts, etc. Stuff that brings the data to life. One of the common asks from some of our early customers is a heatmap of the world to visualize their sales/reach and see changes over time. Visualizing progress per sales region, etc. I think sales especially has a lot of opportunities for better lead generation and qualification as well. i'm currently unemployed but i have experience as a CSM and account manager for multiple companies (all have used Salesforce) if you ever want feedback or bounce ideas. This would be awesome, we're in hardcore MVP build mode right now - when we get closer to launch I'll hit you up. I'm a little delusional, but I think there's ground to steal back from Salesforce. Most folks I talk to hate how complicated Salesforce is (one even calls it Salesfarce). I've heard a story or two about smaller companies trying to adopt it and wasting a hundred thousand or two implementing Salesforce only to have it never get used. On top of that, you need to train your employees to use Salesforce effectively. The key is simplicity, building a CRM that anyone can instantly understand just by looking at it. This is insanely hard but I think we'll pull it off. I'll show you more what I mean when I reach out. Thanks! I've been writing https://urbanismnow.com weekly for a year. The idea is to bring you the best ideas from around the world to inspire action where you (c)are. It's been going well for a side project and now I'm thinking of expanding to have a directory of urbanists on a map so you can easily find people involved in the local discourse and how to get involved. I am finally making my own blog. I have been only planning for ages. I found that I had a lot to say for the past years working on AI, and I want to record them somewhere. I do not expect a lot of visitors or at all in fact. The blog is going to be just for me to remember stuffs and to keep track of them. I am using hugo to build suckless static pages. LLM helped me so that I don't need to read all their docs. I haven't finished it yet nor posted a single blog. But there will be one soon. I have been working on Buckaroo - my table display library for dataframes in notebook environments. Buckaroo adds table and analytics features like histograms, summary stats, sorting, and search to every dataframe. Recently I have been working to make it work better with large datasets. This involves making it lazy for polars, allowing it to read arbitrarily large files no longer requiring loading the entire dataframe into memory. When a large dataframe initially displays, no summary stats will be available. Summary stats are computed in the background in groups of columns. Then results are cached per column. To accomplish this I wrote a polars plugin in rust that computes hashes of columns. Dealing with large data like this is tricky, operations sometimes crash, sometimes take all available memory, and sometimes they just run for a very long time. I have also been building an execution framework for Buckaroo. It uses multiprocessing based timeouts, and the caching to execute summary stats in the background. Being able to control the execution, recover from timeouts, crashes and memory exhaustion opens up some interesting debugging tools. I have written methods that take arbitrary groups of polars expressions and produce a minimal reproduction test case through a git-bisect like process. All of this assures that if individual columns of a dataframe fits into memory, summary stats will be computed for the entire dataframe in the background. And because it is cached, the next time you open the same dataframe, the stats will be display instantly. When exploring data I do this in an adhoc way manually (splitting up a dataframe by columns and rows), but it is error prone. This should all be automatic. I will be presenting this at PyData Boston in December. The Column's the limit: interactive exploration of larger than memory data sets in a notebook with Polars and Buckaroo I'm trying to learn 3D scanning and printing: I have a few small projects that I want to do to develop the skill: I want to 3D print a shell that goes over my car fob: I keep leaning on it and setting off the alarm. The shell would make sure the buttons never get pushed. I want to 3D print a sleeve that keeps the NCAS dongle in my car charger. I really wish there was a dongle that stayed attached with screws or similar. I'm working on a book about using WebViews for cross-platform music software GUIs. It has a particular focus on performance, which I gave a talk about at the Audio Developer Conference last year: https://www.arthurcarabott.com/adc-2024/ As part of it I am building a code generator to generate shared type definitions in C++ and TypeScript (plus serialization, comparison and cloning). https://lunchtrain.se/
A one glance page to find what to eat for lunch in Lindholmen, Gothenburg, Sweden Working on this made it really clear to me how a LLM can bring real value to a backend, it excels on processing very differently structured dynamic data (something if done without an LLM would require quite specific code - which would lead to more development time and increase time to market) Been continuing to work on my daily puzzle game: https://videopuzzle.org Yesterday was the one year anniversary, meaning there are 365 videos to unscramble. :) I'm wrapping up a v0 of a personal website soon [1]. This has been kinda "coming soon" for almost 7 years now - every single time I attempted it in the past, I would stop it prematurely due to a lot of yak shaving and I could never finish it fully. Or more commonly, I would get bombarded with busy times as well. I'm happy where it's landing so far but also appreciate any actionable feedback to make it better (!). Under the hood, it packs a Rust Axum API, plenty of ffmpeg, and some hobo infrastructure [2] here and there. [1] - https://nid.nogg.dev working on a end to end pipe like for robot model . no where near complete but still https://github.com/Priyabhunia/roboVLM I built Nible.news , a news app that delivers International and Dutch local summarized stories in about 60 words for quick reading. Would love feedback from the community The Board: A feature board that vibe-codes the top voted feature into itself every night: https://theboard.stavros.io Check out my project at https://www.MobiusClock.com: A 3D WebGL Clock on a Möbius Strip that shows 24hr time on a 12hr face. The hour indicator follows the edge of the strip, thus must make 2 turns to return to its starting point, giving you a 24 hour clock. The minute and second indicators move along the middle of the strip and thus return to their starting points in only one turn. Has the ability to rotate! Just added a new feature: a 'Fast Mode' button to temporarily speed up the hands, which helps visualize how the slow-moving parts work, how the hour indicator moves along the edge. Would love feedback on the implementation. If you happen to have an old or spare iPad or tablet, you can open my mobius clock page in a browser and set it on a shelf (plugged in of course). Kind of like a weird wall clock... Working on https://greatreads.dev/ A place to find great blog articles by regular folks related to dev/tech world. Wondering about the best way I can add a weekly newsletter built on top of the content currently being ingested and still looking for more sources to add to the database (let me know if you have any good recommendations). I am working on something similar but with a different view. I like to get random essay to read whenever I am bored or in-between tasks. So I developed this: https://read2reflect.com/ I have added only about 35 essays for now. Might pick up some from your list too. Updating partijgedrag, which is a voting compass based on how parties vote on motions in the Netherlands! Apart from that I have a personal SaaS idea I want to release soon. Its something that started as a joke but the joke is still not finished Learning that RCS is even more of a monstrosity and a lie than I thought a few years ago. Yikes. Lots of groundwork a decade ago setting the stage for "the carrier creates a common service anyone can interact with" (like sms/mms currently do, which would be great) but in practice it's pretty much 100% "only the carrier app or Google/Samsung messages has access to literally any of it". Yeah I'm not gonna touch it and I'm going to actively encourage people to disable it. Use signal instead. I'm thinking a lot about the ARC-AGI ML benchmarks, especially the "shape" of the dataset and what that says about how it should be solved. I think there's good reasons to believe that deep learning - at least differentiable SGD backprop style - is a bad fit for this specific benchmark, due to the tasks being almost entirely discrete symmetries, and also having so little data to approximate the discrete symmetries with continuous ones (considering deep learning to be the learning of continuous symmetries). I think that a more explicit and discrete approach is the way to go, and it's possible to build something surprisingly general and not heuristic-based even without gradient descent, guided by minimum description length to search for both grid representations and solver functions. I'm looking for teammates for ARC-3 so hit me up if this sounds interesting, I'd love to chat! I made a viewer on my website to build intuition for my preferred perception algorithm which is entropy filtering + correlation. Pretty neat to check out the heatmaps for random tasks, there is a lot of information inherent in the heatmap about the structure of the task: https://synapsomorphy.com/arc/ Working on a desktop app that lets you ask questions on your data files like csv, json, parquet and excel in plain english without incurring heavy LLM costs. Launched a new plan as well that gives unlimited question-answering for just $20/month. Truly unlimited, no strings attached. I'm currently working on porting Android 16 to a Galaxy S5. Why? For learning and fun. The next step is to debug kernel logs with uart. I am trying to build a local setup where I spawn dockers (fetched via skopeo) as systemd-nspawn machines in userland (rootless), with network managed by a service that uses netkit devices to setup network in their empty network namespaces. I am looking at using Sommelier to manage wayland. The end goal is to have a laptop with an easy way to build lab environments which is secure and rootless. Made a game: https://fourmula.awsum.info I think it's too difficult in its current form. I just released my SAT Writing textbook: https://www.amazon.com/Matthews-Guide-Digital-SAT-Writing/dp... It took me two and a half years to finish. Now I've got to market it. I have been working on Jigsaw Pic: https://jigsawpic.com My 7 year old niece loves jigsaw puzzles, but a lot of the time I see her during family trips where taking puzzles along wouldn't be feasible. We usually have an iPad though. I plan to add more puzzle categories soon. Great and simple tool. I like it. The only thing was that a lot of the pieces / cutouts were identical. Would suggest to add more shapes and variety. A website that lets you match watches with different straps to get a feel for how it'll look. Mixing and matching watches with different straps is something that I really enjoy doing. It's not often easy to tell ahead of time whether the combination will work. I'm working on an app for hiking, check it out: https://apps.apple.com/app/lost-trail-hike-with-friends/id64... We are building end-to-end accessibility compliance tool[1] that will take care of auditing, remediation, verification and generation of ACR/VPAT. Because of the well bound nature of the problem space, we are able to unlock a lot of power from LLMs and put together a good end-to-end product that delivers the promise. Still early days. I know there are lot of folks who care about a11y. I would love to chat and learn from your experience. https://github.com/smartcompanion-app/audioguide-app An open-source audioguide app that helps museums and cultural spaces create engaging visitor experiences. Feel free to give me a star on GitHub. Bread and butter stuff. Pulling together all of the assorted algorithms and data structures I implemented in C over the years out of necessity - lists, trees, stacks, queues, hash tables, memory pools, etc. - aligning the APIs, cleaning up and merging into a library. It's a background project but super fun. This and several parsers - JSON, some config file formats, and parsers for some GPS / GNSS receiver data protocols. FSMs also always feel like nice, clean fun. And prematurely optimising every bit. Mindscope 2 : https://mindscopeapp.com (iOS / macOS) A hierarchical text canvas for organizing thoughts and taking notes. I wrote v1 years ago and now spent about year rewriting it in SwiftUI and adding all my dream features like reminders, deep linking, and lots more. Currently in TestFlight beta, nearing release. I’m working on a performance capture library for Python because I often need to know the performance of backend systems I maintain. I frequently build tooling to capture performance and save it for later analysis. I/O operations get costly when writing lots of data to disk and creating good real-time analytics tools takes a lot of my time. I wanted a library that captures real-time performance analytics from Python backends. https://github.com/jakeroggenbuck/kronicler This is why I wrote kronicler to record performance metrics while being fast and simple to implement. I built my own columnar database in Rust to capture and analyze these logs. To capture logs, `import kronicler` and add `@kronicler.capture` as a decorator to functions in Python. It will then start saving performance metrics to the custom database on disk. You can also use the middleware for FastAPI. You can then view these performance metrics by adding a route to your server called `/logs` where you return `DB.logs()`. You can paste your hosted URL into the settings of usekronicler.com (the online dashboard) and view your data with a couple charts. View the readme or the website for more details for how to do this. I'm still working on features like concurrency and other overall improvements. I've added a lot since the last time I shared on HN. I would love some feedback to help shape this product into something useful for you all. Thanks! - Jake I built a website (https://hpyhn.xyz) for hacker news users for reasons: 1. hn comments are valuable, I've spent a lot of time going through hn comments.
I think there are valuable comments buried in the threads with fewer points, so it's not enough to just read top3 threads. 2. Sometimes a good post is ignored due to a bad title, sometimes I still have no idea what the post's theme even after I read a few paragraphs. 3. I want to filter out some posts I'm not interested in, but I realized I need read some other posts it's not a simple yes/no problem, so I gave every post a interesting score based on my own preference so I want a tool to save my time while not missing out too much on hn A new spin on my slow baking location intelligence data union (https://wherelabs.info).
This week I’m thinking about whether it makes sense to provide a location history ‘vault’, designed to let users expose their location history to LLM’s as context. 1. Langsam - https://github.com/cellux/langsam This is an AST-walking interpreter for my personal LISP dialect written in C. Once it's ready, I would use it to implement a low-level, statically typed language (Schnell) as a Langsam library. The goal is to gain the ability to JIT-compile Schnell code (sexps of a statically typed language) from Langsam. Once this works, I would rewrite Langsam in Schnell so that it becomes a fast bytecode interpreter. With the faster Langsam (and the Schnell built into it) I could build a little OS called "Oben". The OS would first run on top of Linux, then I would attempt to bootstrap the entire stack on bare-metal. I already have a Forth dialect implemented in assembly language (Grund/Boden). The idea is to implement Langsam in Grund and then bootstrap the entire Grund -> Langsam -> Schnell -> Oben chain on something like the qemu q35, later on a Raspberry Pi Zero 2W and maybe even my own hardware (ie. an FPGA board like what Wirth et al. created for Project Oberon). 2. MTrak - https://github.com/cellux/mtrak This is a TUI MIDI tracker written in Go. Not too user-friendly: one has to enter raw MIDI messages in hex into the tracks. Can be connected to synths like Fluidsynth or Surge XT via JACK MIDI. Unfortunately it takes a lot of CPU time, probably due to the use of BubbleTea (and no time spent on optimization). 3. Mixtape - https://github.com/cellux/mixtape Beginnings of a programmable, non-realtime audio sample generator/manipulator written in Go with an OpenGL GUI. I was thinking about how people in the old times cut up the magnetic tape which contained the sound bites and rearranged them to build something new. What if I'd implement a data type called "tape" which is basically a piece of sound and then provide operators in a Forth-like language to create and manipulate such tapes. Each tape could be a sound and then these could be stitched together to form songs. Who knows maybe an entire song could be represented as a hierarchy of these tapes. Each sound or song section could be its own file (*.tape), these could be loaded from each other, maybe even caching the WAV generated from the code of a tape to speed things up when there is a huge hierarchy of tapes in a project. Lots of interesting ideas are brewing in this one. I continue to work on My Financé, my personal finance tool. I’ve been struggling to find substantive traction, so I’m trying to niche down to make the tool really helpful for people who want to quit their jobs. I built a rudimentary planning and forecasting engine, and am trying to run paid ads to see if the signals resonate with people. I don’t love ads, but maybe trying to understand them will further inform my opinion on them. One thing I would love to come up with is a way to make the app fully local first, while continuing the ability to sync accounts via plaid. It would be great to not be able to see people’s data at all. Im trying to figure out if there is a good user experience I could provide while minimizing the amount of data I actually have access too. Maybe this feature won’t matter to my primary customers though, I’m not really sure. I still have a ton of fun working on it, and if it never really makes any money I consider it a great success for my personal learning. Link for the curious: Completely bootstrapped online counseling platform focused on affordability ($25/week!), accessibility and doing the right thing by clients and therapists. Currently only available in NY, FL, TX and Singapore with plans to expand as budget allows. A gamified pill tracking app featuring a cute mascot: https://apps.apple.com/us/app/pill-buddy-meds-tracker/id6742... The mascot gets annoyed if you haven’t taken your pills on time. Im finalizing the Google Calendar integration for Ganttify. https://gantt-chart.com It will allow users to fully manage their calendar in a Gantt chart. Complete with customizations like dependencies between events, custom colors for time blocks and custom icons for single-day events (“milestone”-like). Ganttify is a Gantt chart add-on for web applications or services that can benefit from a Gantt view. My goal is to expand the number of integrations for Ganttify and release a new integration every month or so. If any of you have an interesting (niche or non-niche) idea to integrate Ganttify with feel free to contact me. I'm working on https://mimicmarketer.com It allows you to define different personas that you can then test marketing on. This allows you to see how different personas will interact with your marketing. Currently, it has a feature that allows you to define basic personas and test them against two types of copy, as well as a tool that grades your email subject lines and bodies against a generic persona, assessing the likelihood of user interaction with the content. My other project is https://eggexplorer.com This is a site I wish I had when building out my flock of chickens. It allows you to see the different characteristics of chickens and which hatcheries sell each different breed. You can also see which hatcheries sell hatching eggs for each breed as well. I’m building Sink It for Reddit (https://gosinkit.com), a browser extension to make Reddit usable on the web. It’s similar to RES with broader support for all the different Reddit UIs (there are 4). It’s mostly free with only old Reddit features gated behind a one time $5 fee. The app has a few hundred thousand users on the Apple platforms but recently it was invited to join Mozilla’s Recommended Extensions program so I’m hoping to grow the non-Apple user base. Just shipped Scrype, a library for devs who want a cool way to showcase their code. It's fully typed. Works with vanilla JS, Vue, React, or just a script tag. Got some feedback that it may not be the best UX-wise but let me know what you guys think! Demo: https://devjeff.info/scrype
Repo: https://github.com/DevChanQ/scrype After creating the feature request for Claude Code hooks[1] a few months back, Cupcake is nearly ready for release. Cupcake is a governance/policy-enforcement layer for agents. Its innovation is binding OPA/rego to agent runtimes (via hooks). I do not believe we will every strictly rely on "better" models in the wild without deterministic guarantees or ways for enterprises to factor in their own alignment - system prompts dont cut it. https://github.com/eqtylab/cupcake Stay tuned for the formal release here in a couple of weeks. [1] https://github.com/anthropics/claude-code/issues/712 Cupcake GitHub: https://github.com/eqtylab/cupcake How big of a threat is AI to your career? Upload your CV and it will be analyzed. You'll also get steps on how to reduce this risk. Still working on this and some things will definitely change, but IMO the system prompt is already solid, so that the response isn't unnecessarily scary on one hand, but not too general on the other Tried it, but it says it can't extract text from PDF resume. Unfrotunatelly, it happens and I am aware of this. In that case: a) you are lucky because your CV is not scannable by AI so it's good if you want to keepyoru carieer as far as possible from AI tools ;) b) you are unlucky: most likely the software recruiters are using to pre-screen applications (and they are using it a lot) is not seeing your CV either so you will be dropped on the first stage, :( work on this if you consider finding new job nowadays c) if you still want to use my tool consider extracting CV's text to .txt or reformat PDF (this will help you with point b) A TUI to monitor your OpenAI and Anthropic usage inside your terminal. https://github.com/htin1/toktop I use codex and claude code daily, also build apps with openai and anthropic api keys, so i always go to openai dashboard and anthropic dashboard to track my usage. Since I spend most of times inside cursor or terminal, I wanted to quickly check my usage without leaving my terminal/ide, so i built this! It's open-source, MIT, and built with ratatui (awesome name). Hydal Product comparison site for electrical goods, currently has 350,000+ products with detailed specifications, and 27,000+ prices. Right now UK only, but we have prices for 27 regions, and just now getting retailer prices sync'd up. I've been working on two game development projects for the past couple of years. One project is for building rhythm games in multiple game engines and multiple platforms. Currently, it works in Unity, Unreal, Godot, SDL (or any C++ game engine), and MonoGame (or any C# game engine), and runs on Windows, macOS, and Linux. I'm working on adding Love2d (or any Lua game engine) and Bevy (or any Rust game engine). I have a few local prototypes of it working in Unity and Godot, but nothing public yet. Still trying to figure out what kind of game I want to make with it. https://github.com/neogeek/rhythm-game-utilities The other is a general purpose game engine in C++ with SDL. It's far enough along that I'm building games in it, but it's more of an exploration into how games are made than a replacement for Unity or Godot. I suppose it could be eventually, but I'm trying to be realistic with what it can do. One thing I'm pretty happy with regarding this engine is that one of the demo repos will automatically build to WebGL and publish to itch.io when changes are pushed. Local only meeting transcription and summarisation for MacOS. Loads of similar products out there, but non that did all of: open source code with attested releases, recorded mic and system audio to work with any meeting app and used Apple Intelligence for private summarisation. In beta, and also just released a experimental version with self hosted Ollama support. https://www.bsub.io - batch processing for developers. You submit heavy duty jobs without worrying about infra, and we take care of execution. We're starting with PDF extraction. Audio transcoding + STT (speech to text) is next. Video transcoding will follow. This allows you to have $5/mo VPS and get media operations figured out. Polishing my dashboard for tracking profit on Solana blockchain for set of wallets: https://imgur.com/813aQsO I want to extend it with a simple overview of most recent profitable wallets to look for new "metas" that i could profit on. This project may or may not end as open source eventually, but i currently keep it private. I've just released my beta of FURS. FURS does for Forth, what headers do for C, namely provide all the embedded configuration information inside a Cortex-M MCU, for the up to 100 inbuilt peripherals. Without this data, neither C nor Forth (or any other language) have any clue about how to use the peripherals. FURS does this by intercepting the Forth user source as it's uploaded to the on-chip compiler and transforming it into language the MCU inherently understands. The Forth user source code is not altered in any way. I've used the Fossil DCVS for the entire FURS project so that all the flowcharts, pictures, code, user doc, trouble-ticket, wiki ... everything is contained in the ONE FILE, under 5MB. This one file gives you a web server so all you need is a browser to easily view all the above from the main menu. Howto:
https://sourceforge.net/projects/mecrisp-stellaris-folkdoc/f... Currently working on training language models steered towards certain "states of consciousness". I have a model trained on publics datasets tied to brainwaves and/eye tracking and text comprehension (have this working well enough to experiment). Now I am training an adapter for various llm architectures to generate text steered to certain neural oscillation patterns (let's call them "states of consciousness" for brevity). I also have a 'rephraser' that rephrases text to elicit these certain states of consciousness. Overall experimenting with creating an suite of tools off my findings with how text relates to the eigenmodes of consciousness. My theory is once I do this I'll be able to do some...interesting things with "AI" agents. lmk if you want to talk about it if you're someone with knowledge in neuroscience/ML. My background is as a Software/ML Engineer so I could use additional thoughts. I do wish I could send a Github/docs which I will soon but this is currently a private project seeking investment for various research/public/private sector applications. https://RadioPuppy.com - Listen to 1000s of online live radio streams. This is a pet project for myself. I love listening to online radio while at work, helps me focus. But I didn't really click with any of the current selection of web apps out there so decided to build one myself. It uses the great API available at radio-browser.info for all the radio information. Been using it as a way to learn how to market a website as well. Learning a lot. I welcome any constructive feedback. Very cool, will be using this. Would suggest that you filter out any radio stations where the URL isn't working if possible. For example I filtered down to "United Kingdom" and then "bass" - 3 of the 6 worked and would rather see ones that are active. Also if possible to apply the country filter within the search bar, took me a second to realise I had to open the filter for country, select that, then go back to my search. When clearing my search of "Bass" in the example above, it reset the search to default (didn't have my country filter) even though the filter was still applied when opening the filter section. Super easy interface to use though, really well done. Hey thanks so much for checking it out. It is annoying when some of the stations don't work. I've done an initial try at filtering them out without much luck but will try again. Good idea about the country filter. Thanks for the feedback really appreciate it! I recently launched a casual math game! https://play.google.com/store/apps/details?id=pipipie.game It's currently only available on Android but I hope to bring it to other platforms soon. I am a disabled developer who has limited mobility in his arms. I like treating games that are simple and accessible for people just to spend time. Would love to hear any comments or suggestions! Oar - GitOps with Docker Compose (think ArgoCD for Docker Compose) - https://github.com/oar-cd/oar claude-review - collaborating on documents with Claude Code, with Confluence-style comments - https://github.com/Ch00k/claude-review Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them. Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods. I created a RescueTime alternative for KDE Plasma. It runs in the background as a daemon and records time spent on each window in a SQLite database. Next step here would be to add a Firefox extension, since a lot of my time is spent browsing the web. Tracking windows on Wayland is hard because the protocol doesn't support it. I hacked together a script using Claude Code that somehow works, but I barely understand how. I'm working on https://pipestack.dev, a workflow automation platform where you bring your own code - as Wasm Components. Think n8n, but you bring your own code and optionally even your hardware to execute pipelines. I'm building an analytics and attribution platform for onchain apps, named Formo. Think Google Analytics + Posthog designed for crypto users and apps! I've learned a lot about data engineering and analytics in the past year. I’ve been working on an idea wishpool. Anyone can post an idea for something they wish existed — an app, a game, a tool, or anything else — and share it.
When more people back an idea, it gains momentum and starts getting built, either by AI or by community makers. The goal is to turn crowd energy into real progress. Tools to help my mental health tracking[0], and sharing with others how I manage my limited amount of energy[1]. They're kind of related, since mental health impacts my energy, so I've needed to prioritize and really make sure I'm spending my time and energy on things that matter. Usually, there's a good mix of things I enjoy doing with things I gain a lot out of. I've spent a lot of time thinking about this! I've used my app in various forms for around 5 years, rewritten multiple times. But now I'm creating surrounding tooling to help others put my mental model for personal life prioritize to use. I'm writing in the "Saving Spoons" Substack as I go, trying to explain why and how I do things, with advice for others trying to do the same thing. I'm working on Argon Chess, a deterministic chess variant with some degree of cheat resistance (hard to describe to chess engines like Fairy Stockfish) and tons of variety. A week ago, I added a way to play friends online a week ago (a Discord Activity) and a simple Play a Dumb AI feature on its website. You can also print the cards for free for offline play. https://argonchess.com/ My booktube channel : https://www.youtube.com/@NevsBookChannel Of relevance - my review of Code Complete: https://www.youtube.com/watch?v=QlY0EGWp7rw Oh nice subscribed! Thanks! Fair warning to any others: It's mostly fantasy and sci-fi with the occasional tech book thrown in Unwound a couple of things from the stack! Finished: the 100%-vibe-coded "GPT-5 reviews all my PRs on max reasoning" GitHub app (which is shockingly effective, https://github.com/Smaug123/robocop - probably nothing new for people who already use some product like this, but I like owning my own infrastructure as far as possible, and GPT-5 and perhaps Gemini are the only models smart enough to do this so I can't take this any further). Currently: back on "write an immediate-mode TUI framework that uses a vdom as its fundamental abstraction" (https://github.com/Smaug123/WoofWare.Zoomies), in the hope that this is the first UI framework that I don't absolutely loathe. Next: using the TUI framework, write a debugger to inspect the internal state of my deterministic .NET runtime (https://github.com/Smaug123/WoofWare.PawPrint) and to step forward and backward in time. Next: get the deterministic .NET runtime to a point where a property-based testing framework can identify the deadlock in some very simple buggy multithreaded code. (The framework is not yet able to run Hello World - did you know that's an incredibly complicated program in .NET? - but it can solve a few Advent of Code problems right now, can perform some limited exception handling, limited virtual method dispatch, limited casting between types. Even getting to Hello World might take a year if I'm unlucky.) Making the Nest 2nd gen thermostat the Google recently bricked compatible with local setups like Home Assistant. I'm involved in 3 projects that are solving this problem from different angles: I’ve gone old school. After reviewing a few people’s CV’s the easiest format was for me to record a video with the feedback, so I put a site together for that: No AI, you just buy my time. I’m also looking to do a couple freebies if anyone wants to anonymise their CV and let me use it for a promo example. I like the path options. Is this US focused or also applicable to UK/EU people? Thanks. I’m based in the UK so have a good grasp on that, but I’ve reviewed someone’s resume from the US just as easily. Generally, English speaking and preferably in a digital related field, but a lot of the common pain points seem to be universal. It’s only difficult when it’s a field that’s highly niche as hard to know what’s common knowledge. I like to play the role of the person doing the hiring, hence why the form asks for an example job description. Interesting, the impression I got from the site was that this is US specific (dollar currency) and not that you're based in the UK. I'll keep your site in mind if needed, I think the video response is a key selling point, great idea. A Python Framework called Artanis, inspired by ExpressJS, to make it easier for JS devs to work with Python ecosystem: https://nordxai.github.io/Artanis/ Curated LinkedIn topics + AI drafting: validating before building I'm exploring building a weekly curation service for professionals who want to write on LinkedIn but struggle with "what's worth writing about." The thesis: In the AI era, execution (writing) is commoditized. The real bottleneck is editorial judgment... knowing what topics matter before they're obvious. The concept: Weekly email with 5-7 curated topics (tech trends, policy shifts, market movements). Each topic comes with sources, multiple angles, and context
Choose your perspective, AI drafts a polished article Why I think this could work: I've been manually doing this for myself for years. Pattern recognition at scale is hard to automate, but pairing human curation with AI execution might work. Target market: ~30M professionals who should be building thought leadership but don't have time to spend on research. Current status: Validating demand before building. The hard part isn't the AI, it's systematizing the trend-spotting and curation process without losing signal quality. Stopping Agents [1] - LLM agents that stop conversations early and save time. Because they're trained using imitation learning instead of RL, they're scalable and easy to deploy with your own data (also open-source!). Mainly targeted at and tested on quickly disqualifying prospects in sales calls, but can be applied more broadly. I'm working on SuperCurate (https://getsupercurate.com), which is geared towards note retrieval and curation rather than note creation.
Think filing cabinet for your notes, web clippings, images and PDFs. I wanted fast search and filters for my Evernote archive so I could drill down and surface exactly what I was looking for. There's also a Web Clipper extension for Chrome. Demos: Search and curation: https://www.youtube.com/watch?v=z4QSIoUL4Uk Web Clipper: https://www.youtube.com/watch?v=8F7QoC7X3fs Search inside PDFs (jumps to page + highlights snippet): https://www.youtube.com/watch?v=t0X9sD-938Q It's free while in beta, would love feedback if you try it. I am learning Godot engine, going through the list of 20 games in order to build up my experience
https://20_games_challenge.gitlab.io/ I am almost done with flappy bird (2nd challenge) Why? I love the old arcade and game boy games, and I want to recreate them to my liking. I also love mechanical systems and space rovers, and I want ro build worlds to explore and simulate these things Thanks for the link to that 20 games challenge. Godot is fun and something I want to get back to eventually! I'm working on _prompt injection_, the problem where LLMs can't reliably distinguish between the user's instructions and untrusted content like web search results. Just published a blog post a few minutes ago: https://alexcbecker.net/blog/prompt-injection-benchmark.html Good post. Thanks for sharing. I enjoyed it as much as I enjoyed your anime list. I agree on many. I’m starting a book club! - Sixty books a year (five books a month) - Self Chosen Books (no forced reading) - Two recorded Salon style meetings monthly - Bespoke software for the group including: shared embedding graph of highlights and annotations, IRC chat with @ for members and books and authors, collective bookshelf - Six members max Learn more here if interested! > five books a month How? I'm a prolific reader but outside of short fiction I can manage maybe 4 a month. Pretty easily doable by reading multiple books at the same time! Averages out to ~50 pages a day. The trick is to always keep the book queue filled, so long books that take a while coexist for a while with a number of shorter length ones Just launched the beta of Yass - an open source Kotlin implementation of the Swiss national card game. I'm working on basi, an alternative/syntax to writing Playwright: https://github.com/zikani03/basi Trying to keep it simple but I can already feel some "design pressure" to think about making the DSL more complete (language) by adding features like loops and variables. Still early days! I'm working on https://yap.town - an SRS based language learning app. I would say it combines the best parts of Duolingo and Anki. Anki is great for memorizing words, but you don't see the words in the context of novel sentences. Duolingo is great for exposure to new sentences, but it's oriented around "lessons" and SRS is an afterthought. (Duolingo is also not designed for people serious about learning a language IMO, it's too easy and goes too slowly.) Had to do quite a bit to get it to work well. 1. At first you would think that if you know all the words in a sentence, that should be enough to understand the sentence. But it doesn't work like that. For starters, words can have multiple meanings. The french word "bois" can mean "(you) drink" or "wood". You want to learn these separately. I trained an NLP model (a gemma3 finetune) that I use to understand the manner each word is used in each sentence: https://huggingface.co/collections/anchpop/lexide-nlp-models 2. Even then, what about a sentence like "you'd better not"? Even if you know the words "you" "had" "better" and "not", you still won't really get this. So I use the wiktionary "multiword terms" category for each language to get a huge list of terms like "'d better" , "you better believe it", etc, and teach these in addition to individual words. And then I only show sentences where you know all the individual words as well as all the terms. This is awesome sir, I'm pretty sure this will get you very rich soon or later. By the way, I have a suggestion, the examples on the answers could be listenable to keep the brain on a learning mode all the time even on side words Great idea, done! And I'm not planning to get rich off of it haha. Right now there's no monetization at all. If lots of people use it to learn a language and avoid wasting their time on duolingo, I'll be happy I work on Robotics, so was recently implementing slamkit in rust. https://github.com/MostlyKIGuess/slam-rs But a lot of what I work on is my classes giving me less time to open source nowadays, but I have also worked in implementing and mashing new Papers coming out in Robotics. Anyone who wants to talk more should please connect! I'm making a game finally! Merge-three + village sim. Hoping to actually take this one to something polished as opposed to the many half-finished prototypes littering my git repo over the years. I've discovered (always knew?) that heavily cutting scope is the best way, and been successful thus far. It gets pretty boring/unbalanced by ~150 turns, but I have some ideas on how to fix. I'm still playing with ways to help de-clutter the board and make use of the economy aspects. After some false starts with ai-gen art, I had fun learning to color the pixels myself. The process wasn't as scary as I'd thought and the results are better than I hoped. https://tower3.dreamofninjas.com/ Inspired by TripleTown from the wonderful studio Spry Fox. I am working on Pinggy (https://pinggy.io/) to make it the easiest tunneling tool. One feature we are working on is an attachable public IP. For those behind CGNAT, they can run this app and get a public IP instantly. Working on IT Asset Management & Endpoint Security, Automated platform for IT teams dealing with asset sprawl and security compliance. Check it out: https://zecurit.com Would love feedback from anyone dealing with endpoint security or compliance challenges.. Very interested in this type of thing. I can't see anywhere where pricing is mentioned, even ranges would be a useful benchmark to know if it's something within budget. Love the script hub, very cool idea. Thanks! You can check out our pricing here: https://zecurit.com/pricing/ We’re also building a script repository so you can run scripts directly on agents from the Zecurit console. Give it a try at https://zecurit.com/signup/ I suspect AI company want improved efficiencies and developing a framework that can be applied in determining the minimal-energy, maximal-efficiency architecture for ai models. Calculating the precise limits, like a Cognitive Event Horizon, where a model becomes so complicated it literally costs more energy to run than the knowledge it provides, and the Semantic Horizon, where it simply gets too complex to be accurate, etc. Lots of cool implications such as around a fundamental mathematical maximum learning rate which results in trying to get anywhere close to that that by doing stuff like aggressively filtering of the data. I'm building my take on a low-touch task completion assistant designed to counter distraction and hyper-habituation. It's starting off as a MacOS app because that's the machine I have. I didn't know Swift or SwiftUI when I started. I now know them somewhat, but the entire app has been vibe-coded. This has made it slow going. Very "1 step forward 2 steps back" until I switched from Claude Code to Codex and GPT-5. I'm hoping to start an initial beta within the family in the next week or two, and then a wider round in January. Working on https://tinythoughts.app, a self-messaging app Today, I am implementing tag-triggered webhooks so they can get triggered based on the tags assigned to messages. Use case: for example, I want to auto-tweet all my advice messages and auto-create linear tasks for `company` todos, auto-start a cursor agent when I tag messages with `Cursor task` For some reason, I got 16 users out of nowhere, so I added a landing page last week. The connector marketplace is next, so that I can share these sub-connectors with the other users. Need a couple more weekends. Agreed with syabro, this sounds very interesting but don't want to give away my number straight away without seeing anything. Would like to have more info but landing is empty
And I don't want to provide my number unless I'm sure it's usefull A game-agnostic social/legal/financial overlay for virtual worlds. Minecraft, Rust, Roblox, etc.: legal ownership claims (vs possession), titles (recognized by other players or not), laws, player-issued currencies. Smart contracts but with as little blockchain stuff as possible. The iron rule is no direct interaction with the world. These are things that players can in theory always start on their own as long as they can communicate. Knowledge management meets spaced repetition: open-sourcing my tool I've been using for the last five years https://github.com/odosui/mt. I am building a WebAssembly WASI runtime for exaequOS (https://exaequos.com), an OS fully running in the Web browser. It will support WASI 0.1 and 0.2. Basic implementation can be tested by running ‘wex’ in the terminal I'm working on a survival game in the line of MC, Valheim and Vintage Story.
Last months have been focused on developing the survival core mechanics on top of building and fighting. Im now entering in the final phase of wiring all the pieces together. Streaming the process daily on Twitch. I'm working on some documentation for my framework/ide (https://glitter.nz). I'm thinking about all the new things I'm really hoping to add. We are a service to help brands navigate the new world of AI agents. Currently focused on helping them increase visibility in AI search but we plan to go beyond that. I'm building a fun writing app that mimics the feel of a real typewriter. Free on iOS + iPad + macOS (Catalyst), and I'm working on adding additional skins, premium features, and Android soon! :) I’m building https://unrav.io : A tool to fight information overload. It lets you turn any article, YouTube video, or PDF into summaries, mindmaps, podcasts, chat conversations or infographics that match how you learn with just one click. We just launched this week the Chrome extension so you can do all this in one click on any page, no login needed (with generous freemium usage). https://unrav.io
https://chromewebstore.google.com/detail/unravio/mbnapibcjcf... Would love feedback from fellow builders. A simple strobe tuner for musical instruments with Odin, Raylib and Portaudio.
https://github.com/dsego/strobe-tuner/ I'm building https://github.com/agentset-ai/agentset, RAG as a service that works quite well out of the box. We achieve this performance by baking in the best practices before any tweaking How does it handle retrieval in a multi-turn conversation? Is there an intent graph involved? Does it summarize past context or keep it all? I'm building an app that helps users memorize Kanji and vocabulary with AI-generated visual and story mnemonics. Right now, I'm adding a feature to practice writing Kanji and another that creates AI comics based on vocabulary you've learned. Next version of my side project, which is a site to perform text to network transformations. Change consists in refactoring the back and front end. Former : nocodefunctions.com: Current: next.nocodefunctions.com Context: https://nocodefunctions.com/blog/jsf-primefaces-vs-htmx-alpi... I’m working on Reflect [0], it’s a privacy-focused app for self-tracking and self-discovery. You can track metrics, run self-experiments, set goals, view correlations, visualize your data, etc. [0] https://apps.apple.com/us/app/reflect-track-anything/id64638... Imo, you really should use a pure white background for the App Store screenshots instead of the current greyish background which looks kind of depressing. I’m building a stablecoin account for workers in LATAM. It helps them protect their earnings from inflation and makes doing taxes easier. (https://www.useairsend.com) https://yournextstore.com
https://github.com/yournextstore/yournextstore I'm building Your Next Store (YNS); it's a Shopify alternative built with React and Next.js. We provide an opinionated boilerplate tailored for tools like Claude or Codex, so designers and developers can build storefronts faster and more easily. It enforces a clear structure to start from while keeping full control over design, animations, and the overall storefront experience. It’s built on top of Stripe, with our higher-level commerce abstractions, like "add to cart", "checkout", "pay", "browse products" etc; plus a Commerce CMS so merchants can manage everything smoothly once their store is live. If youre planning to sell something online and want a modern solution, hit me up! :) Frontend framework in JavaScript that requires no build step, relies on DOM and SSR and can be used to build both SPA and hybrid apps without VDOM, js templates, hydration or putting HTML (or worse, css) inside JS code. It'll also have a very sophisticated declarative state manager which makes managing state and ui transitions a breeze. It's basically anti-React. can you share a repo link please? Sure: https://code.qount25.dev/qite/qite-js
No docs yet, but I suggest you go to test/demo for examples. You can actually see them work if you run it with `node test/server.js`. State manager isn't there yet, but it's coming. A new ping pong paddle design. My backhand is OK but my forehand sucks. Grip styles for standard handles usually end up favoring one side or the other. I'm making a handle shape that's easier to get the blade angle right on both sides. Hopefully a couple more iterations on the 3D printer and then I can have a functional prototype made. XferLang, a data-transfer and configuration language to serve as an alternative to JSON. Most obvious features, at first glance, are no commas and no need for escape characters. Other useful features include processing instructions, extensible data-substitution rules, and support for comments. Currently only implemented in .NET; plans are to rewrite the core in Rust and provide language wrappers around that core. Currently working on a website that lets you add any form of troll CAPTCHA to your website or allows you to create a redirection with shortened link. It is a fun project and oh boy I really enjoy solving CAPTCHAs on random websites. I've been building a little toy computer and assembly language that's interpreted in python. Pretty close to the first release (and introductory blog post) and a lot of fun to build (and learn a bit more about real assembly as I go). Building a docs website [1] for my speech-to-text CLI tool, hns. I use it 5-10 times daily to transcribe my voice, and a few developer friends I've shared it with have also adopted it for daily use. They like that it runs in the terminal and keeps all data local. So, felt like I should write down guides for new users to get started quickly and to highlight key use cases. Building this documentation website using Docusaurus. This is my first time using Docusaurus, and it feels like a very nice tool for quickly developing a documentation website.

Allez Go: an fencing sports broadcasting system + AI referee Inspired by shot tracer in golf as well as the "10 yard line" in football. Also built secretsofmaps.com (but that's more a side project)
Would love some feedback! Developing a fingerprinting method for identifying music masterings! Like Shazam but to tell what version of an album you have. The idea being able to compare measurements to see what mastering you're really getting - because they are NOT all equal. With the remasters and stealth replacements on streaming, it seems like every other month I wake up one day and my favorite music sounds worse (or is gone...). Now I can measure it and help find what versions I really want to collect! I may end up trying to make a fingerprint database/tool that sits in between MusicBrainz and Discogs. That way hopefully the community can standardize and quantify some of this info that only lives ad hoc in Steve Hoffman forum threads or partially on sites like https://dr.loudness-war.info I've working on an AI Thumbnail Generator for making YouTube thumbnails and social media images the last few months. https://thumbnail.ai/ I’m working on Radiant Computer. It’s a new kind of computer that attempts to part from the unix heritage and offer something really accessible and modern. I've been working web scraping using LLMs, I just shared one of the libraries I created to get structured data from arbitrary pages: https://news.ycombinator.com/item?id=45870231 Instead of sending the page's HTML to an LLM, Hikugen asks it to generate python code to fetch the data and enforces the generated data conforms to a Pydantic schema defined by the user. I'm using this to power yomu (https://github.com/goncharom/yomu), a personal email newsletter built from arbitrary websites.

Working with a group of friends on a "microcontroller-for-makers" kind of thing called the MakerPort. (https://makerport.fun) Sort of similar to an Arduino or micro:bit, but uses the MicroBlocks programming editor (https://microblocks.fun) created by John Maloney, who was the original team leader for Scratch at MIT for 11 years. The hardware includes an mp3 player, I2C ports, accelerometer and true capacitive touch sensors. https://recipin.com Recipe extraction and archiving to avoid link rot and blog spam. No tracking, no JavaScript, no AI[0], and just a dusting of CSS. Source available to run your own server if you’d like (https://github.com/bradly/recipin). I’d like to add importing from a Pinterest account and continue adding support for all the creative implementations of the schema.org recipe format that different sites use. [0] My partner has a bunch of handwritten family recipes, so I’m trying out an optional extract from a photo of a hand written or magazine recipe that uses AI. Not required and I may pull it out into its own service that spits out schema.org recipes. We’ll see. The OCR -> schema.org pipeline would be useful, I've been doing it manually prior to importing to Mealie. I'm building one project a week for the next 25 weeks for my newsletter. First, I want interesting content for the newsletter. Second, I want to try to grow the newsletter to put out something fun and joyous. The world needs more good fun. I recently launched Queens Hourly puzzle on App Store. https://apps.apple.com/us/app/queens-hourly/id6751763916 Every hour, new Queens Puzzle (LinkedIn style) is available to play. No leaderboard, no stats, nothing to buy, just pure play. Every user gets the exact same puzzle to solve for that UTC hour. I would love to get some feedback from the community! Working on developing a suite of apps around photography, from cameras to editors and utilities. The goal is lightweight, composable tools with clean interfaces that respect user agency and privacy, provide technical clarity, and make you a better photographer by encouraging mastery over your tools and offering new ways to approach picture making. Also broadly honoring the (almost) 2 century old history of the craft and drawing inspiration from pre-digital processes and approaches. Got a number of updates to existing apps and new ones in the works, I’m excited for the full long term vision I have that I plan to sum up in an essay at some point. Currently Apple platforms only but the plan is also to break out of that down the line. Helping my recent MBA grad sister make a simple python script to fit here resume to a JD using openAI's api.

The goal is to push beyond JWTs and Zanzibar-style policy engines by giving every machine-to-machine request its own embedded, verifiable authorization logic in a small capability token. These tokens can be delegated, restricted, and verified locally with no extra network calls required after getting the token. Early use case is replacing API keys with identity tokens that expire, delegate, and prove possession and then can be used for easy step up to fine-grained authorization. There's some pretty interesting authorization stuff you can do, like having multiple parties sign off before a token is valid or requiring a series of micro-services sign a token for it to be valid. I'm working on rebuilding Playwright from the ground up, but focused on automation and self healing using LLMs. It's called Stagehand (https://github.com/browserbase/stagehand) and we just released v3, which is a total rewrite. Interesting. I rewrote Playwright to run completely in a Chrome Extension without CDP or chrome.devtools for no practical reason at all. I started to do it like Forest Gump started running. It can't get past bot protection so pretty worthless from a browser automation point of view. [0] What I don't understand is why the need to rewrite Playwright instead of just patching it. Playwright (or Puppeteer) has addressed every edge case that has come -- especially race conditions which are a monster to deal with -- up over the years and by the time you do the same you will have Playwright. Why is rewriting or rebuilding Playwright from the ground up needed? [0] https://github.com/adam-s/cordyceps/tree/main/pages/side-pan... Very cool. I make a consulting business out of packaging selenium scripts into windows apps for small businesses, do you have any desire to turn this into a saleable product? Stagehand is our open source project, but the company behind it is called Browserbase - https://browserbase.com/ where we run headless browser infrastructure as a service. So no interest at this point, Browserbase drives the revenue that funds Stagehand! Originally started in 2012, I’m (still) building log.soccer - a stat-tracking tool for amateur soccer players. This is the third or fourth iteration of the site, which until this year mostly served as a glorified résumé project to showcase the latest framework or tool I had just learnt. Thanks to ChatGPT, my productivity went through the roof this year, and I finally shipped an MVP that might actually be useful. It’s a standard Django + React + AWS stack. My raison d’être is to build an Apple Watch app that tracks match scores in real time. 2026 hopefully. Just launched a startup/life style business where I use AI to help people practice for upcoming interviews - https://hiredcoach.ai Already have been told by some users that the interview prep they got from it has correctly predicted several of the actual interview questions they got, crediting its prep for their breezing through the interview rounds. I'm really hoping it helps a lot of people! LINOG.ph is a live earthquake tracker for the Philippines. The Philippines deals with thousands of earthquakes a year. Whenever the government volcanology and seismology department detects earthquakes, they post it on their official website. When a major earthquake happens, a huge number of people try to visit the site, causing downtime for up to an hour. LINOG.ph caches earthquake data from the official government website and the U.S. Geological Survey site, and makes them highly available to the public. I built this after seeing friends and family donating and providing support for affected families after a major earthquake in Cebu. This was my way of helping out. Two super typhoons have hit the Philippines in the past two weeks, so I'm also considering adding in typhoon tracking. Why doesn’t the government put Cloudflare or something in front of their site? Working on https://gametje.com (a Jackbox games competitor). Been working on the Android TV app lately. Will probably start creating a new game next week with acronyms similar to the old game Acrophobia from the late 90s/early 2000s. A visual editor for creating video games on the browser and on Linux desktop: https://stickyfingies.github.io/g2ngine I've done this with C++ in the past, but ran into substantial friction with the CMake toolchain, specifically w.r.t: - cross-platform compilation with large dependencies (vcpkg ports) - running multiple compiler chains in the same build step That second point is necessary if, for example, there's some AOT asset processing work that uses a native tool, and you're building for web. Expressing that some targets should use the emscripten toolchain while others should use the native toolchain, and interleaving between them, was a mess. TBF, I haven't done that with cargo or build.rs yet and it may prove to be equally frustrating. Other features: - undo/redo using a stack of swappable states - serialization to disk (native) and LocalStorage (web) with some integration tests in progress but I am not satisfied with the correctness of my implementation: I want to *guarantee* that all information is preserved round-trip, but I also want a Patek watch. - OBJ, GLTF, GLB models are loaded as "blueprint scenes" which are distinct from the "world scene." I made this distinction at the type-level because "scenes" are groups of entities that use newtype IDs (`LightId(u64)`, `MeshId(u64)` etc.) as primary and foreign keys to refer to each other, and I wanted to make it impossible for an entity in scene A to hold an ID for an entity in scene B. Instantiating a blueprint requires creating new IDs for every object. - W.I.P. Alpha rendering, depth sorting, overhauling the material system to support multiple shaders (tough) that may be compiled after the engine itself (even tougher, a lot of runtime dynamic state and schema validation stuff), physics, scripting - oh yeah! - Scripting using JS on both web (runs in browser itself) and desktop (uses a packaged JS runtime `Boa`) but Boa doesn't perform well on desktop in debug mode so I'm exploring other options. For the past few months, I've been building a health tracking app called LogBuddy. I got tired of using separate apps for nutrition, workouts, weight, and period tracking. So I built LogBuddy to handle all of it with a dead simple interface. That way, all the heath data I'm tracking would be in one place.
Right now there's an Android APK available. If there's interest, I'll publish to the Play Store and build an iOS version too. Would love to hear your feedback if you try it out! Here's the github repository: https://github.com/aabiji/logbuddy https://github.com/dmjio/miso-lynx Building native applications for iOS, Android and Huawei devices in Haskell. This sounds very interesting. You say “native” but miso generates JavaScript, right? I’m not familiar with mobile development. Can you run JS natively on mobile devices? I wanted to try a non-trivial project with AI assistance and I enjoy writing compilers, so https://vegen.dev I'll write up my experience in a blog post I'm still working on WithAudio (https://desktop.with.audio). A one time payment Text To Speech Desktop App. Because I think everything doesn't have to be a subscription. In October I finished the PDF parser. It was a big challenge extracting PDF contect with correct paragraph breaks on user's computer locally. I'm gonna write about this soon. Now I'm working on a web extension that talks to the app that run locally on your system so you can use WithAudio in your browser with very good performance, 100% local and private. Workflows and Case Management for Lending use cases like Small and Medium Business loans and Merchant Cash Advances. I'm working as the Product Designer on these features for a Document Data Extraction AI company. Working on building a chatgpt wrapper with real time stock market data. More than 70% investors are using Chatgpt for their investment analysis these days, but the data is quite dated since it's all based on web search. Trying to fix it. I'm making an app for self-tracking. Combining elements from habit trackers, health logging and journaling. Built for rich customization and local-first. Want to be free of rigid structures of many existing apps while providing a better UX / usability than using a spreadhsheet. Landing page + waitlist: https://dailyselftrack.com/ Created a web game: https://www.teqgame.com I really liked the concept of games like cards against humanity, quiplash, whose line is it anyway etc. However, there was no virtual way to play it with a group of friends. Quiplash required steam setup (which was not possible on my corporate mac). So i built this as an alternate to build upon the formula. [still in alpha phase so lots and lots of bugs] I made a voice-input only social media. It has pictures too. But you can't type anything. Made it in a weekend with Lovable. https://SightRead.org - free, ad-free, etc, vanilla js (except for the abcjs notation library) web app to practice sight reading. Currently rhythm-only, but more is planned. I posted in this monthly thread first time in May when I launched a daily logic puzzle, Clues by Sam. Since then it's grown significantly, and I couldn't be happier! The game has a farily simple frontend, but there is a fairly complex constraint solving algorithm as part of the puzzle making process. What makes the puzzle quite unique is that you can't "guess". You can only make guesses that are provable by logic. The algorithm ensuring this has worked flawlessly for months now (though I've manually inserted some silly mistakes once or twice). Today's puzzle is one of the hardest to date. The difficulty resets on Mondays, and then gets harder again towards Sunday. Clues By Sam has become THE morning fixation in our household since I first heard mention of it a few weeks ago - super fun, thank you! Experimenting with various AI models via GitHub Co-Pilot on an extremely niche project to see how far these models have progressed. Used like ~60% of the premium quota to develop the following projects: website: https://murajah.pages.dev/ Play Store: https://play.google.com/store/apps/details?id=com.murajah.we... Manual audio splitting tool for the above project: audio-splitter-6b3.pages.dev/ I've always been skeptical of AI-generated code. This is my first experiment with AI agents, where the full code base, implementation, debugging, and deployment are done using AI Agents MCPs. Used VS Code all the way, i.e., all the source codes, including the code to generate the Google Play Store APK. I only reviewed the source code before committing and helped debug by suggesting ideas/algorithms. Mostly used Claude Haiku 4.5 like 75% of the time, where it failed, switched to the sonnet 4.5 or GPT 5 codex. Interestingly, when debugging, sometimes one model struggled even after numerous iterations/feedback loops, but then the problem was solved instantly as soon as I switched to another model. The source codes are available here: https://github.com/wasi0013/Murajah https://github.com/wasi0013/audio-splitter Initially, I thought the audio splitting could be done automatically using some AI models from Hugging Face or Whisper. But the audio files have some complex repetitions; the output was miserable. So, for now, this splitting is done manually using a Web UI (The audio splitting tool splits the large audio files into multiple small audio files, think of it like a long paragraph is split into multiple sentences.) I will attempt again to automate this splitting task using AI, after drafting a game plan for tackling the challenges. I'm thinking of using energy drops and other similar factors to create segments. Disenhackifying one of the last pieces of my KaithemAutomation server that still feels not best practicesful. Device driver plugins used to have a very simple flat key value, strings only format, with a set_config_properties function to tell the host what kind of UI to show. That's all getting replaced with JSON schemas, with some auto-upgrade shims so old config keeps working. It's one of many things that now seems completely insane, but made sense when I had way less experience a long time ago! Also still on and off working on my BLE/WiFi based Meshtastic-alike. I’ve been making a story-based podcast for Spanish language acquisition with accompanying activities called https://listenreadinteract.com There’s a free course for true beginners with no login/sign up required. https://listenreadinteract.com/start Working on Spine AI, a visual workspace to think across multiple AI models. You can chat, branch, and connect 300+ models on an infinite canvas: useful when you need to explore tradeoffs, check blind spots, or generate assets (research, slides, prompts, images) from the same board. Try it without signup: https://app.getspine.ai/guest Porting LevelDB[1] to Seastar[2], for internal metadata storage in Redpanda[3]. Before you ask why can’t something off the shelf be used, seastar has unique constraints around its runtime and its memory allocator that means we can’t reuse an existing library. 1: https://github.com/google/leveldb https://web-framework.com, a lightweight PHP framework on Slim and PHP-DI for ORM, caching, auth, etc. (an alternative to Laravel/Symfony for small apps). I kinda gave up on building apps for Rocknix (since there is no easy way to distribute software) and instead have been looking at my apple watch. I ported over some software for workouts that is streamlined. I'm working on a way with MDNS to sync data to my Linux PC automatically when I'm at home. If it works out, maybe this could be a way for me to replace the compromised Apple Music app with something that actually syncs to my music on my desktop. My friend and I working on PennyPost, financial analyst that solely focuses on your spending. It looks at your spending across all your accounts, categorizes, identifies patterns, trends, runs predictions and sends weekly/monthly summary email. No apps or dashboards, just insight. Plug in once and forget. Takes 5 minutes to keep track of your spending. We are still at early stages but you can check it out here https://pennypost-landing.vercel.app/ Appreciate any feedback you might have! I'm working on a man in the middle proxy for BGP, which can fix and inspect routing sessions on the fly. Like a firewall for the BGP control plane. Some time ago I was building a mitm proxy myself, then I found out about: https://www.mitmproxy.org/
Maybe you already had it in your radar That's for HTTP/S and related, as parent said his is for BGP which is a completely different protocol Still hacking on some data tools: DuckDB for stream processing: https://github.com/turbolytics/sql-flow Lightweight kafka stream processing using DuckDB as the execution engine. 300MiB runtime can easily handle thousands of messages / second. Working on a Kafka Connect alternative: https://github.com/turbolytics/librarian Right now mongo replication (through changestreams) is supported to kafka. Working on Postgres support right now. I made a direnv-like utility which hooks into your shell to allow using Nix flakes for dev envs / dev shells anywhere: https://github.com/dfrankland/envoluntary This helped me bridge the gap between installing packages declaratively via NixOS / home-manager and defining them for each project being worked in via flake.nix / direnv / nix-direnv; which was needed since most projects don't use Nix. Basically small data tools for myself. A non-bloated HTML, CSS and pure Vanilla JS framework to create dashboards. A cross-platform JSONL viewer where I am learning ImGUI. Haven’t found any other open source GUI framework that‘s small, provides out of the box components for tables, sorting I am working on methods to automate my VC firm. We have a small team and many different tasks to do. I’ve had success with using LLMs to help us automate various projects. But I appreciate any open source tools, techniques, readings, etc. if anyone knows any! https://NitroQR.com
Building the one stop QR Generator with a crazy amount of aesthetic customizability.
Already at a pretty functional level, focusing on marketing now.
Got something new cooking for the holiday season. Hopefully launching this weekend. Working on a small embedded vector database lib (à la SQLite). Just finalized the file format, it works pretty great so far.
Besides, it’s an excuse to learn rust and low level programming in general. I've been building with local AI, on Apple Silicon. It's only 8mb, but runs 30% faster than Ollama. I'm working on marketing my dedicated game server host https://stratos.host - it's a simplified product compared to traditional companies, using a desktop app to detect games being launched. Next release of my app (8 years since initial release) - adding minor features and minor bugfixes. Video Hub App - browse your local video files with a beautiful interface (and scrub-able thumbnails to see multiple screenshots) $5 for anyone https://videohubapp.com
Free for anyone https://github.com/whyboris/Video-Hub-App We've been tinkering with building realtime talking head models (avatar models, etc.) for a while now, and finally have something that works (well enough)! Operates at ~2x realtime on a 4090, significantly faster than that on enterprise grade GPUs. You can try it yourself at https://playground.keyframelabs.com/playground/persona-1 and there's a (semi)technical blog post at https://www.keyframelabs.com/blog/persona-1 The main use case we designed for was language learning, particularly having a conversational partner -- generally we've found that adding a face to the voice really helps trigger the fight or flight response, which we've found to be the hardest part of speaking a new language with confidence. But in building out the system around the model to enable that use case (tool use on a canvas for speaking prompts and images, memory to make conversations less stale, etc.), we think there's potential for other use cases too. I am building a foundational layer for building C++ apps using Bazel. I am working on creating a standardized set of paths and third party libraries that work seamlessly across multiple developer teams. Allowing library upgrades to happen transparently in the background. This will enable developers to focus on business specific logic and not have to worry about the intricacies of the build system and allowing to "magically" work in the background. This is allow foray into Bazel and using it as a learning exercise to master it. I'm working on a video / post on how to solve the 1 billion row challenge (https://github.com/gunnarmorling/1brc) and get a competitively fast result while keeping the code readable and maintainable. So far I'm within spitting distance of the winning entries without using any unsafe code or bit twiddling tricks or custom JVMs or anything like that, and having all the concerns nicely separated and modularized. Excited to share soon! I finally started modding a total war game (Warhammer 3). I played the series since the very first title, Shogun and I always wanted to improve the control over units and add my custom AI to not micromanage everything, but assumed it would be too time consuming and distracting from my main work. And well, it likely would have been. But thanks to LLMs, I finally decided to give it a go and got something basic working in a short time, hurrey for AI assisted coding! Feels empowering to be honest. No idea if I will really implement the main ideas, that I have since a long time, but I know that I can now if I want to. I built a chrome extension (with over 600,000 downloads) that lets you chat with page, draft emails and messages, fix grammar, translate, summarize page, etc..
You can use models from OpenAI, Google, and Anthropic. Yes, you can use your own API key as well. Feedbacks are welcome. A Mac-based video manager that automatically transcribes, translates and summarises videos. I process information best through reading, so I built it to manage my growing collection of training course videos, webinars and meeting recordings. Currently working on adding RAG search to make it easier to query content. Also building a CMS and static site generator that runs entirely client side in the browser. Pick themes, model content an publish to clean HTML. It also makes content available beyond just the browser, eg in a command line TUI. I'm going all in on my side project CodeBrew, a Java IDE for iPad. Currently working on OpenGL support for 3d graphics, as some schools requested the feature. Also I'm finally pitting some work into aquisition, which has turned out to be much more fun than I anticipated. Go check it out, its free to try, with a one-time purchase full version: https://apps.apple.com/app/apple-store/id6475267297?pt=11914... I'm Building a Speech-to-text app with AI workflows. Building with Tauri, Rust, TS, React and Tailwind. The first version is out:
https://voice-ai.knowii.net Nonoverse[1], an iOS puzzle game about nonograms (image logic puzzles). So far all levels have been handmade pixel art. I’m now testing machine generated puzzles with random “pixels”. This is an interesting challenge because I still want levels to be solvable and fun. I recently released 15 new puzzles like this and I’m preparing a new update with more. [1]: https://apps.apple.com/app/nonoverse-nonogram-puzzles/id6748... Been building an agentic movie database. https://memovee.com already in private testing. The code for the agent is here https://github.com/upmaru/memovee-tama Correct and performant way to calculate historical value of a portfolio. I want a pure function, but taking a date as input is insufficient because users can edit holdings, and securities can split. Weighing the tradeoffs of doing this calculation server or client side. That'll be an architecture shift away from my current set of background jobs fetching state and towards something more functional and on-demand. On and off working on the Navigation API for Node, Bun, Deno, & as a browser polyfill. Has 90% test coverage, makes use of web platform tests to verify compatibility, and is in use by some larger companies already with the Navigation API soon to become a baseline in evergreen browsers. The Navigation API effectively is async state navigations. The likes of React has recently added Navigation API support to make use of the browser reload indicator. https://github.com/virtualstate/navigation Along with working on a startup day to day :) Building https://ottex.ai - a native MacOS app to solve repetitive micro tasks on a computer. - Transcribe voice to text (especially useful when you need to explain something to Claude code ) - (soon) select text to instantly Check grammar / Improve writing / change tone of text - (soon) select text to Translate between languages I discovered that I have a few 10/20$ subscriptions (grammarly, raycast, wisperflow) that do embarrassingly simple stuff I can one shot with cheap SLM. So I decided to build a one app specialized in small repetitive tasks on computer. Month three working on my game development resources website: https://raizensoft.com/tutorials/ I write almost daily article about libGDX - my most favorite code-centric game framework. There are now over 100 articles covering topics from basics to advances. I plan to post more because this is more or less a passionate project. In the future I hope it evolves into a definitive resource for learning game development with Java and libGDX. I am working on a repository for AI Intent Driven Development at https://github.com/Exadra37/ai-intent-driven-development/. An Intent is a self-contained document that describes a user request. It is composed of three main sections: WHY (the motivation), WHAT (the requirements, often in Gherkin language), and HOW (a detailed, step-by-step implementation plan defined with tasks). This approach ensures clarity and alignment before any code is written. I recently released a game: GunStopperDrone Game
Single player game, race against the clock to defuse a dangerous situation using a drone against an armed attacker.
https://game.gunstopperdrone.com/ Building vet. The goal is to automate open source package vetting beyond just CVE but actually identify code capabilities, malicious code and other security sensitive attributes through code analysis. - Zig bindings for AVIF/HEIF - Local-first app for comparing hardware builds, down to the individual component feature level: specs, benchmarks, even cpu extension support, lanes, how many speakers in X laptop, dolby atmos? screen panel manufacturer(s), etc. Basically, no-nonsense real product comparison for transparent and fast decisions. Working on https://outcrop.app, a knowledge base for software teams with instant search, realtime collaboration, and LLM-driven workflows. It's built using Rust and friends. I'm looking for more early testers! :) I've been obsessed with reticulum. It's a network over other networks.
https://konsumer.js.org/nomadnet-js/
https://github.com/konsumer/rns-lite The protocol is fairly simple, encrypted by default, and works over lots of interesting transports. It's really cool, but as far as I know there's no complete C++ implementation for embedded platforms, and I still can't figure out how it actually works. Does the gossip flooding mean every single node needs to know about every other node in the entire mesh? I have a project vaguely inspired by this and Meshtastic that tries to make use of existing internet tech, while falling back to local links, instead of trying to replace the Internet completely. It's very much WIP, I'm planning to get rid of all of the automatic reliable retransmit stuff and replace it with per channel end to end acknowledgment.
https://github.com/EternityForest/LazyMesh# I started working on a Arduino implementation, but it needs more testing. It works like your address is the hash of your pubkey, and you can announce that or not. Is there any kind of DHT like routing for the addresses? Woudn't the announces make a lot of traffic without that, if you ever got to thousands of nodes? No DHT. it seems to work fine for 1000s of nodes without it, though. The TCP testnets, for example, are pretty highly populated. That's pretty impressive, I wonder how it handles LoRa or Bluetooth? I assume every packet is probably at least 32 bytes, if 1000 people send one every ten minutes, that's going to be 700 bits per second or so, right? Working on adding Apple Intelligence to my macOS app built to analyze iOS app size metrics. I'm hoping to have a locally running assistant that can act like an iOS build engineer to provide optimization opportunities and more: https://apps.apple.com/us/app/dotipa/id6742254881. Right now my app allows users to export build metadata as JSON which can be interpreted by LLMs for analysis, but I'd like to have this work on-device. https://www.ottoclip.com - Create product-focused content that stays in sync with your product. Create a script for a product demo or tutorial for your app using an extension. The script is used to generate your product content in multiple formats (narrated video, interactive demo, looping animation, and in-app guide). Whenever your product changes, just update the script and regenerate everything. No manual re-recording of video, syncing of audio, or any other post-production steps. https://github.com/FarisZR/knocker Knocker, an http knock based access service for your homelab that works at a reverse proxy or firewall level. It's a more convenient albeit less secure alternative to VPNs like tailscale.
It's more convenient because it whitelists the enite network, and it's less secure for that reason. I’m building a typed, array-oriented dataflow compiler that takes small declarative schemas and emits plain Ruby and JavaScript, with a C path. It has a mid-end with inlining, common subexpression elimination, constant folding, dead code elimination, loop fusion, and LICM. Demo to try it out:

https://github.com/amuta/kumi I’ve been working on an online LPC speech encoder as part of my embedded sound tools: https://buzzer-studio.atomic14.com/ It’s starting to sound pretty good. I’ve had quite a lot of help from the community with lots of useful feedback and suggestions. It’s been fun. I'm working on a poker server to allow holdem bots to play against each other (https://github.com/lox/pokerforbots) and a Pluribus-level bot that plays on it (https://en.wikipedia.org/wiki/Pluribus_(poker_bot)). Enjoying writing some really fast Zig implementations of hand evaluation and CFR-based solvers. Main Project:
Radar Analysis Software. Side Project:
Sentiment analysis (±10) on news articles to be used ( along with other indicators ) for stock buy/sell recommendations. I am working on PocketWise (https://pocketwise.app) a lightweight personal finance tracking app. Goal is to make double entry accounting simple and approachable for everyday use. It’s my first project of this kind, so I’d really appreciate any feedback. I built https://forvard.org/ with Tauri + Svelte; Forvard is a accomplishment tracker where your data lives locally (think of Obsidian but for career tracking), it has a bit of smartness to summarize your accomplishments (without sending your data over the network). I'm working on fixing bugs and adding couple of features! Made a website to host a blog! Right now it's empty except for one post describing the process of setting up the blog. I plan to add more stuff once I finish this semester in college. Website: https://ngonella.com/ I have a bunch of ideas and small projects I would like to write about, so I'm really excited about this. I’m building Culink — a platform for curated link collections. Not random bookmarks, but organized and shareable collections you can actually discover.
Think Pinterest for links. Day 13: 27 collections live, and people are already creating their own — which is exciting to see! I'm working on a boardgame with the help of AI. It's way too easy to create placeholder art with an n8n pipeline, but GPT-5 regularly fails at writing and debugging LaTeX which I'm using for all of the card creation. Specifically, TikZ is often outside the ability of GPT5 to successfully write or debug. This week I’m publishing my open-source, email based commenting system for websites. Ultra low-power LoRa stuff with STM32 microcontrollers. Powered by solar. I'm working on a web app that creates easy-to-understand stories and explainers for the sake of language learning. You can listen in your favourite podcast app, or directly on the website with illustrations. Most of the testing so far is English/French/Japanese/Mandarin, but I'm eager to add more languages if anyone is fluent and willing to help me evaluate the text-to-speech. I am working on a browser plugin that lets you edit Supabase database tables just like Excel, until it's ready. Then you switch to the main branch and the tables will be read only I'm working on an open source library in golang to get in depth system information from macOS. Here's my work so far: https://github.com/BinSquare/powermetrics-go I am currently working on a fork of Alt+Tab replacement Switcheroo to show all available windows in a tabular format. Current windows in the center. Apps with many windows on the left sorted by process name (e.g. Excel or PDF windows).

I refused to learn JS for years, but turns out it's not as bad as I thought, and TS makes it really nice, plus I like (to my surprise) SolidJS' JSX interpretation quite a lot. Half vibe-coded, half breaking things and learning a lot. A modern QuickBooks, based on beancount, WorkBill (https://workbill.co). You can play with it at https://demo.workbill.co. Unlike traditional accounting platforms we expose the ledger model directly which enables our customers to model complex transactions even when we do not have direct support for it. Been working on this for a month, and it uses Elixir, Phoenix and InertiaJS with React. i made a self-destructing text-sharing service for fun today. nothing crazy but its open source, free, and self-hostable. I work on Puter (https://github.com/heyPuter/puter/); an open-source, self-hostable internet computer. People use Puter for an incredibly wide range of things, including cloud storage, web hosting, coding, AI, and gaming. Right now, we're mostly focused on improving performance and making sure that it's as fast as a regular desktop environment! This looks fun! But the fact that the self hosted version lacks support for some core apps is sad, I'd love to be able to build puter apps! Any plans for an app store-like ecosystem? http://www.taxmax.dev - helps companies deduct more engineering spend. https://github.com/s1liconcow/skyshelve - persistent python dictionary on S3. Used this to create a durable execution layer to do some of the analytics for the above. I'm working on a command-line tool for advanced full-text search of written documents. It works in a completely different way than grep, so it can do a lot of operations that grep fundamentally cannot like proximity searching. I called it Wosp for word-oriented search and print. I released the first functional version a few days ago: https://github.com/atrettel/wosp A notation and IDE for writing fractal poetry (LambdaConf video https://www.youtube.com/watch?v=adjg2LeQMvk) A constraint-solver for a novel algorithmic theory of harmony (cadence.is) a word game based on transformations from one word to another (unreleased) email my username at thekeyunlocks.us for access to any of them or if you want to talk shop! I have made a co-op roguelite tower defense game inspired by the old Warcraft III maps. A major inspiration was YouTD. You can play it here: https://defense-of-solaris.com/ I'm adding an overly elaborate item and levelling up system to the adventure mode of my chess variant AI sandbox: www.chesscraft.ca Items have a prefix and suffix system similar to Diablo 2 so I'm having nostalgic fun building it. None of this gives any advantage to the chess games you play. It's just a pointless cycle of gems, items, and experience to get more gems, items and experience. Seems fun so far. New (open source) PostgreSQL index type for analytics workloads, which is a read-only drop-in replacement for B-trees. Smol is multiplicatively faster than B-Trees and radically smaller. Help, alpha testers, etc all welcome. Sorry RDS/Aurora users: smol is for embedded and self-hosted pg instances only for the foreseeable future. Working on a computer algebra system at http://axcas.net I released some public domain code for computing Groebner bases (F4 and FGLM). I'm hoping these routines will find their way into more systems. I'm working on a Yelp alternative called Vibehuntr -- just something different to browse venues using Google's API, with a social layer so I can see what my friends like. It's very rough around the edges right now and it might be completely different by next week. It's been a fun experiment in vibe coding on a full stack. https://vibehuntr.io A multiplayer game prototype, written in Rust, using Bevy + egui for graphics. Think of it as a bare bones implementation of a game like Runescape, mostly to test out current LLM capability. I haven't found much value in LLMs for coding beyond very self contained tasks, but some people speak highly of it, and I want to be sure that I'm not missing out. So from time to time I give new tools a try. This time is "Claude Code on the web". I've put in an estimated 50 hours so far. It has a client and an authoritative server. The client displays 3D graphics with some placeholder models. From the client, you can click on tiles and move to them, or click on enemies to pathfind and attack them. You can right-click on tiles or monsters to open a menu with options (attack, trade, move). There are some unit tests and a few integration tests. Right now the issues that Claude has been unable to resolve after a few attempts are:
* Attack animations. I'm trying to get it to raise and then lower a rectangular block to simulate a sword attack. It really doesn't get it, and it's harder to write tests for compared to movement and server-client networking.
* "Entity interpolation". Rather walking entities instantly moving from tile to tile, movement should flow smoothly. I have Claude Pro ($20/mo) which let me make a few commits per day. After a few days of that, Anthropic offered $250 in credits to promote "Claude Code on the web". The credits expire after two weeks. I'm now five days into that period and have gone through $50 in credits. It is heavily rate limited and frequently locks me out for multiple hours after only a few interactions, but it's free credits so I can't really complain. AI Copilot for brick-and-mortar retailers (https://fastquery.ai) Perfect usage metrics. Store staff spends 35hr per week using my software in a ~7 employee per shift setting. No churn. Bootstrapped past $100k ARR on my own, just onboarded a co-founder. I'm working on https://teeming.ai, trying to solve the information asymmetry problem in the job market. The project has been a huge learning curve for me - I started out as a skeptic of how generative AI could solve real problems (rather than just create noise) but now think that, like the internet, it can create a new kind of abundance that will be harnessable in all sorts of interesting ways. Hey everyone! I built a site that shows your next age milestones, all on a single page. You can see your next milestone age for each type (like your 10000th day) and save it to Google Calendar. It looks simple, but I learned a lot building this site: * To calculate age in planetary years, I had to look up their orbit and rotation info * The lunisolar calendar took me quite some time to figure out (it is not the same as a lunar calendar and even changes by country) * Adding the dog and cat age equivalents even led me to cubic splines Link to the site: https://ageequivalent.com/ i'm building a camera app that can connect two iPhone peer-to-peer, no server needed. I’m still working on https://opus.cafe/ outside my full time job. It’s been a fun 3 year project. Just launched on iOS and am in user acquisition phase. Totally new learnings here! Getting users is definitely the hard part... I can build something all day https://github.com/codeflash-ai/codeflash/ Codeflash optimizes any Python code for performance by using AI and verification. We make all human and AI written code super-intelligent by discovering new algorithms and fixing any performance mistakes. In the philosophy of selling shovels in a gold rush, I have built a Markdown Viewer for Mac which is optimised for AI coding with the likes of Claude. It is simple but powerful supporting all formatting but also diagrams so you can get Claude to generate beautiful ER, or state-transition diagrams for your documentation. It also supports math notation, file links and has a cool table of contents feature It's in the app store: ViewMD I'm working on a _boring_ business - a CRM for pilates and yoga studios (https://www.usemojo.app/en). Most tools in this space are bloated or built for gyms, not for someone juggling reformer classes, cancellations, and back-to-back privates. It started when a friend who runs a studio showed me her system: printed calendars, WhatsApp messages from clients at midnight, and sticky notes for who paid. I'm trying to make something quieter. It should feel like an assistant, not another tool to manage. Bank Rank — an automated bank account that dynamically allocates your money across the best accounts to maximize your rate at all times. We’re doing an alpha launch in Q1 2026, and if you’re interested, sign up at bankrank.io/waitlist or email bankrank.alpha@gmail.com Currently working on secure file intake for Intercom. Recently spoke to a customer and turns out file intake is just a part of the bigger story, currently thinking about processing files, e-signature, client portals and so much more. Lesson: speak to customers! working on https://careroute.ai - triages people to right site of care, estimates their visit cost with their insurance before they go, and lowers bills after visit by having an AI voice agent negotiate on their behalf. Triage works for all regions, cost estimates and bill negotiation is US-only. I'm building a scraper in Golang based on Colly to do two things: * Automatically train the scraper on the structure of the page to acquire the data you want, and * Clean and structure the data into a format suitable to go into a relational database I got sick of doing all that manually for some pricing data I wanted to monitor on some suppliers sites, and I've always wanted to contribute more to open source and give back. I'm building a tab manager extension for Chrome, that also kills duplicated tabs. Why? The one I used died (Manifest V2 only, and was not updated). And I wanted to test one-shot it. Incredibly it worked! I have found that duplicated tabs can be useful e.g. for pages where footnotes are not hyperlinked in the text. When this happens I open a duplicate tab and scroll to the bottom of the page on it. oh, for sure, that's why the extension shows which tabs are duplicated, and I can kill the duplicates individually, but also has a kill-all-duplicates button I'm working on my own code review app powered by local or self hosted LLMs. It started as a way to lint my own code and took off from there. It's basically like greptile or co-pilot, but has some things that they don't: I'm a writer, non technical, and I'm building Eyeball - https://tryeyeball.com/ Eyeball is a bookmarks app that turns your own saved links into hyper-personalized playlists. It's like having a personal curator in your pocket that sends you a weekly issue of your own personal "magazine" on Sundays. A database populated with audio metadata (including a link back to YouTube or Spotify or whatever) that includes vector embeddings for the audio. That way I can grab clips of music I like from YouTube, generate vectors for them, then find similar things in the database. It's off to a rocky start though, as I've initially populated it with YouTube-8M and AudioSet, neither of which are music-specific. The search results can be... Weird. I am working on WeatherLockscreen.koplugin.
A KOReader plugin for kindles, kobos and other e-readers that shows the forecast on the lockscreen. A FLAC encoder/decoder written in Guile scheme. I struggled to get the decoder working with most test files for a while until recently. It's more or less a fully functional decoder now. It's also 1:1 with the reference meta-flac command currently as well. I created this recently but have let it fallow in the last month. Planning to update it over the next few days / weeks. There are a crazy number of directions I could take it. Would be great to collaborate with others on it. In particular I want to explore building the "alpha arena for AI house price prediction" https://tailgator.app, playing around with serverless Tailscale nodes https://coolinary.app, simplifying cooking and recipe ideas https://capi.tax, preparing capital gains tax reports from foreign brokers for German income tax (still closed) As a very recent pet project (and pretty much work in progress), Equations Explained Colorfully (KaTeX + Markdown + TypeScript) https://github.com/stared/equations-explained-colorfully Thinking on good export formats (except of taking screenshots and Pull Requests, obviosuly). LaTeX and Typst?
A remark plugin? https://www.miscbeef.com/octopoda Multiplayer QWOP-like where you control one leg of an octopus. I'm further ahead in the development than shown here, hopefully have the finished thing out with support for multiple games within a month or so (would be faster if I didn't have a job lol) I’m building Cozy Watch, a macOS app that brings GitHub notifications straight to your desktop. It tracks pull requests, CI results, and mentions in real time — so you know when you’re needed without checking GitHub or digging through emails. It has a menu bar for quick access and a clean desktop UI for more detail. Some years ago, I co-founded a startup that would run workflows when email messages arrived, any email from any source was parsed and it would trigger "actions" that could include notifications - this sounds like a good use case for it! You don't need the service to expose an api to listen in, since most services end up sending email as last fallback. Thank you for you feedback! Do you still run that startup? With Cozy Watch, I use the GitHub API, never thought about using emails as triggers. I’ve actually got GitHub emails disabled, they can get pretty spammy. Sadly no, the feedback loop with users lacked consistency and we never got around finding use cases. One of the visions for it was to help people clean up inboxes, because as you put it, some sources can get pretty spammy.
I'll keep an eye out for Cozy Watch, I hope you are successful! Spending all day every day thinking about how to make coding agents better through configs and dev tools If you're interested in following along, check out https://www.npmjs.com/package/nori-ai A filmmaker community for those wanting to showcase their work. Right now everyone's got their own squarespace and the problem is that about 0 filmmakers also want to be web masters. IMDB? Ads everywhere.

A great way for actors, writers, and directors to represent themselves. Feedback welcome!
-M@ Building https://pricetracker.wtf but life got in the way lately. Now looking to migrate bits and pieces to pg_lake from hydra/citus columnar. building a location-based game that captures Taiwan's absurd convenience stores density[1].
Players stand at any 7-11/FamilyMart/etc, take a photo showing you can see the next store, walk to it, repeat. Chain as many stores together as you can. It sounds silly but Taiwan really is this convenient - you often can see 2-3 stores from one spot. Here[2] one route where you can actually link 7 convenience stores in a row!

Some weeks ago I launched https://woomarks.com a Pocket replacement. Here it is hosted on my website https://roberto.fyi/bookmarks/ Working on a mobile astronomy app that uses AR to determine your unobstructed view and predicts what you can see and when Predict? Interesting!! How do you plan to do that? We have an API if you need one. We recently launched https://bestkundli.com, which does the prediction thing. I've been working on an open-source platform to build agentic workflows. I really wanted a Figma-like experience for building agents. Apache-2.0 license: https://github.com/simstudioai/sim Building a simple service to share content and simple sites in free time. Recently implemented sso with google. Would love some feedback. Improving the open source automated documentation maintenance workflow I setup https://entropicdrift.com/blog/prodigy-docs-automation/ Any feedback is very welcome. Slowly but surely: - A learning tool in Python for Arrays and Algorithms - A prototype agent-based configuration management system in Perl - Trying to reinstall Arch Linux on a laptop the second time around (lost my install notes :D) Mostly doing all of it for learning purposes. A food aid grant program to help anyone do mutual aid. Its grass roots activism meets the current SNAP cut madness. An LLM-powered 'offline' journaling/mindfulness app that draws on ancient philosophy. Designed it initially to help nudge my own habit along & keep things fresh/interesting every time I sat down for a scribble-sesh. World model for AI agents. Doing process mining of missions, operations and logistics to transform them into digital twins. AI agents can then leverage these digital twins as world models for control or prediction. https://getcriticly.app, a critical thinking toolkit which helps you think clearer and learn faster. I'm building a cursor style ai agent but for planning hikes/trips. It does context management and tool calls into data sources and navigates the world to find interesting places. Should be getting out of private beta this week! https://wanderfugl.com Personalized audio streams for language learners. Ideal for during driving or while doing chores. At the intermediate level lots of learners struggle to find suitable content that matches their level and interests, more than a few learners turn to notebookLM podcasts to provide that, but that's a bit of a hassle to set up. So I built a platform that generates and manages infinite and shareable streams around your interests or specific vocabulary. It also provides live interactive transcripts (karaoke / teleprompter style) if you need it. Core features work but still rough around the edges. Happy to help you out with any issues you encounter, languages to add, feature requests etc... Working on asking whoishiring not to forget the freelancers next month. https://news.ycombinator.com/submitted?id=whoishiring Edit: oops nevermind it's a goner. Currently working on the first helpcenter that writes itself. The tool makes it super easy to create help articles in any language, just by clicking through a process. The first results are super promising! Working on https://ziva.sh/, an AI agent for game development. It uses MCP to integrate with Godot, a leading open source game engine. It's coming together really nicely, targeting a beta release later this month. If anyone is interested in game development and wants to be a beta tester, lmk :) Free live course on how to make an ai business from scratch https://aititus.com/100k There is a lot of repetition when it comes to building AI system. Frameworks don't help. No-code builder are still too rigid. We are making "batteries included" API to bring agentic AI into any platform. Working on a CLI tool to sync packages between NPM registries. I'll be pushing the code here once its done: https://code.hangdaan.com/foster/kagami https://github.com/benjajaja/mdfried mdfried, markdown viewer for the terminal that renders headers as Big Text via the new text-sizing-protocol or as images. I work on Harbor (https://github.com/av/harbor), it is a project to save hours when setting up LLMs locally. I pre-integrated over 50 different LLM-related projects, added a nice CLI and a Desktop app on top to manage the configs. I have a comprehensive agent system. Currently working on SIP calls with different models including realtime. https://github.com/runvnc/mindroot Building a set of experiments that explores LLMs visual understanding of your photos to learn about you, especially given the recent learnings from deepseek-OCR.

https://ceo.getbeyondx.com I have two side projects I continue to make some headway on: a practice call platform (practicecallai.com) and an iOS baby tracker / newborn app (https://apps.apple.com/us/app/lil-baby-tracker-newborn-log/i...). The last month has had its ups and downs. Ups = some local-area doulas have started sharing the baby app in a big WhatsApp group & growth is starting to pick up. Downs = my first vibe-coding horror story. For PracticeCallAI, the subscription flow was failing and somehow outside my test coverage, so I've been missing out on new subscribers for the last two months. In an effort fix it, Replit Agent - which I have been loving otherwise - truncated the table that stores all of the user calls. and their database rollback is throwing errors. So that's been fun. systemg - "Systemd, for busy people". https://github.com/ra0x3/systemg I'm personally tired of getting stuck in config/deployment hell every time I want to deploy a long-lived web service. Sure I eventually learned how to use systemd, but systemd has SO many things baked into that I simply don't need. systemg is a lightweight process supervisor that features everything you'd typically want when running/managing production web services in the wild. Would love feedback. I love that it's Rust based, but being busy is exactly why I like Systemd, it Just Works, as long as you don't need to customize the OS at all. Building a tourist app for my local city here upstate New York, since nobody in the local government office can be bothered. Hi HN, we’re a Milan-based fintech startup developing FELKO, an AI-powered data platform that helps banks and credit-holders standardize, monitor and act on debt portfolios in partnership with collection agencies! I am building a community driven data aggregation platform for the Michigan tech ecosystem. This is just a promo page.

Also added a YouTube audio conversion api. A mobile game! Made with Godot and Swift, a casual manic arcade thing where you pop animals in increasingly exotic/banal locations. I'm working on formalizing https://arxiv.org/pdf/2508.18475 (A convex polyhedron without Rupert's property) in Lean4 I'm only on lemma 11 at this point, and up until that point the paper has been fairly easy to formalize (modulo my unfamiliarity with mathlib). The repo is here https://github.com/badly-drawn-wizards/noperthedron Evals for programming languages with formal verification. It's not clear how far we are from good coding performance in less popular languages in general, and formal verification has some quirks on top also. I am working on a web app that doctors/NPs/PAs can use to automatically rewrite complicated and verbose medical progress notes. The amount of time medical providers spend on documentation is ballooning, and only a small portion that time is actually spent doing medical decision making. The rest of the time is spent incorporating (ie copy editing) data as it comes in from imaging/bloodwork/consultant advice. The goal is for the app to be: entirely self service, without needing EHR integrations able to persist and reuse the user's writing style, without actually saving any of the notes HIPAA compliant (obviously) Selfhosting via yunohost, especially loving Immich and Actual Budget. I'm not in IT but I use Linux and it has been easy enough for me to set up. Also making personalised Christmas t-shirts in Inkscape. I love what you can do with open source tools! Been nerd sniped recently so am working on a Rust version of markdownlint-cli2. I'm tired of having a node dependency in my projects and this seems like a constrained enough problem space that I'll actually get around to doing it. Just got a 3d printer (Bambu a1 mini) and my girlfriend brought home a whole bag of plant cuttings.

Trying to streamline pet travel compliance and making sure nobody gets stuck at the border with the help of AI and some veterinary partnerships. Building an ai powered threats deception proxy. It's a honeypot system that uses AI to mess with attackers. When someone tries to hack your app, it detects them and serves up fake responses based on attack type. The system learns from attackers behavior and creates convincing decoys to waste their time and frustrate their efforts. It's basically a trap that gets smarter the more attackers poke at it.

Using transformers to understand fitness data Is anyone working on or knows a library for evaluating LLMs for application features and/or application features that use LLMs? I am wondering what people use or if anyone has their own solution. There would be so much subjectivity to this.

It’s currently quite stable. The only known issue is that it can take a while to detect a timeout when the system is suspended and woken up again (there’s no portable API to detect suspend/resume). Since then, I’ve been working on a simple TUI email client based on notmuch and maildir. So far it works really well for processing email, but lacks any capabilities for handling attachments, composing, sending (these are obviously on the roadmap). Oh I'm super curious about your notmuch project. I've been wanting an email client that's just a tui on top of notmuch. Wonder if we can pair up?

But of course the programmer in me needs to make my own software to design patterns with code. Enjoying using paper.js to do all the complicated math to calculate lengths and angles. I just finished a little webtoy. It's like a comic strip time machine - you can see a virtual newspaper comics page for any date in the last seventy years. V happy with how the CSS came out, except I spent a lot of time on an "ink bleed" newsprint effect that (oops) only looks good on HiDPI monitors... lessons learned I suppose Porting antique operating systems (PalmOS) into antique kids’ toys (Fisher-Price Pixter Color): https://x.com/dmitrygr/status/1986329723224441227?s=46 All-in-one router/nas/firewall/adblock/app server (each piece optional) Declarative and reproduceable as it is built off of NixOS, but administered through a UI, so the user doesn't have to know this. All state managed in a backup bundle, so it can be hosted at home or in the cloud. Goal is to have a box you plug just like a wifi access point into your modem, follow a simple web-based installation flow, then you are running a personal cloud. Website is self-hosted by HomeFree, but installation instructions are very out of date, which I'm working on right now. There are now installation ISOs that I will soon add a link to. I buy and operate e-commerce brands that sell on Amazon, and I'm working on handing as much of the operation of the business off to AI as possible. Doing this both for actual time savings for myself and also as my big-picture eval of new AI models + products as they come out. I also started a Substack to document it - here's a recent post on using Gemini to screen inbound emails with prospective acquisition targets via a Google Apps Script that evaluates the listings in those emails daily: https://theautomatedoperator.substack.com/p/screening-inboun.... In network code: most people just let the OS choose a default adapter. It works fine, but it makes it hard to write software that works across machines with either (1) multiple NICs (and/or networks they point to.) or (2) multiple external Internet IPs. Look at STUN, for example. A STUN server that lets people test what type of NAT they have uses two IPs. For such a server you have to manually specify the addresses to bind on to make for sure its setup right. As it goes, writing network software to do simple things like "bind on all local addresses", "bind publicly", "bind on all", is harder than it sounds. There are edge cases on different OSes and address families, so manually managing IPs is hard to do. My network software lets devs easily manage NICs and routes they support without guessing about addressing. Additionally, I've written a bunch of software with the library already to do things like NAT traversal. So its really my own redesign of how to do networking on the Internet. Designed to hide a lot of the messiness. I'm still improving code quality so it's not ready yet. But I've been dog fooding with a lot of software written in it and smashing bugs every day. Project page: https://github.com/robertsdotpm/p2pd
Built this recently with it: http://ovh1.p2pd.net:8000/servers (server monitor for public STUN, TURN, MQTT, and NTP servers. Only checks every 4 hours to avoid spamming them though.) https://gametorch.app/sprite-animator Create video game sprites and animations via prompts. Pretty excited because I've started to get high volume, repeat customers. Ahhh this is exactly what I'm looking for! I don't see any pricing on any pages. Would love to know how much this costs (I don't know what 455 diamonds is worth) as there's a few sprites that I'd love to animate and use in my app. Not a fan of signing up before seeing how much I'd have to pay. The examples look great though. 1 diamond = 1 cent Prices are about to drop dramatically. Many of the models dropped >80% in price since initial launch. Any time I have a reduction in cost, I pass the savings directly on to users. > The animations cost $0.32 ( 32) each. Not sure if you just added this in or I overlooked it, but exactly the kind of transparency I love. Will give this a try. -- EDIT - Did an image generation using the OpenAI 4o model, then ran through the lowest quality animation. This is awesome and first pass is very strong and usable (around 100 diamonds used). I look forward to seeing prices drop more and the asset pack area fill up. Keep going man, really awesome stuff. Manabi Reader: Japanese learning through reading I recently added FSRS (besides also having Anki integration). Now I'm working on replacing the need for reviewing flashcards by having reading activity automatically mark flashcards (current and future) as reviewed, so that you can get many of your reviews in just by reading native materials that interest you instead of sacrificing most of your study time to contextless flashcard grind. I'm also working on a manga mode using a new manga OCR tech I have licensed out of academia that is ahead of state of the art alternatives. This project now sustains my full-time focus. Looks good. Hope you'll do an Android version sometime. It's native SwiftUI and Swift so I want to avoid a rewrite. I am experimenting with porting my Swift code to web via WASM, now that SQLite WASM backed by IndexedDB is usable so I can reuse the data layer too. I'm also evaluating https://skip.tools for running my SwiftUI on Android. Either of web or Android would be great. Looking forward to trying it once one of them becomes available. This looks super cool. I love to see people working on language learning tech. I'm working on a language learning app too but it only really works well for indo-european languages. That said I would still love to collab or talk shop, my contact info is in my bio I'm working on restoring (or really resto-modding) a 1980's Japanese arcade machine. https://share.icloud.com/photos/00ajYWxKpZmYrh6KmlHOxW4tA I was able to get the original 15khz CRT monitor up and running by recapping the board. I decided that the control panel was unsalvageable, and insufficient for what I wanted to do, which was make this cabinet compatible with most any game that would have run on a cab like this. I decided to use RGB lit buttons, so I could change the color's depended on which game was loaded. I used an ESP-32s2 to emulate a keyboard, and accept serial messages from the host computer that changes the button colors. I also incorporated a Stream Deck in the control panel for auxiliary functions. I was able to write a node application to run the stream deck (with the help of a library) since there is no OEM software for linux. By far the most challenging part was getting a suitable signal to the CRT. The first thing I tried was using the Raspberry Pi's GPIO pins through a VGA666 board, but this limited my colors to 16bit, which makes 3d games look pretty awful. Next I tried using a downscaler. This got me 24 bit color, but resolution switching doesn't work with this method. I'm trying an AMD system now. Apparently the linux driver lets you set custom resolutions, and output 15khz (and 25khz for that matter) right from the VGA port. I plan on doing a writeup after I near completion. ArtCraft [1], a source available Adobe + AI. Here's a demo / trailer that shows it off: https://www.youtube.com/watch?v=NNHSTfWbkaA If you're into movies or filmmaking, it's a fantastic AI tool for consistent, fully-intentional scenes with deliberate set and actor blocking. It's also the cheapest model aggregator service out there. You can log into every AI image and video provider directly and don't have to pay me anything to use the tool. You can use your Sora account, Midjourney account, Grok account, etc. It'll soon let you log into other aggregators like OpenArt, plug in your FAL API key, etc. so you can use your credits/funds wherever they happen to live. Unlike the other "model aggregator" websites like Higgsfield, this is a desktop app written in Rust that you can keep. It also has highly intentional 2D and 3D design surfaces especially built for design. Text prompting sucks for artists and designers, so I'm trying to put image and video design onto canvases that you can intuitively mold like clay. Here are some short films made with ArtCraft: https://www.youtube.com/watch?v=H4NFXGMuwpY https://www.youtube.com/watch?v=tAAiiKteM-U https://www.youtube.com/watch?v=SuVW8l-_O3I Would love to hear feedback if anyone tries it out. Users post small games to social feeds. Scroll like a social network, jump into and play any game by tapping on it. Games are served into fully locked-down, sandboxed iframes for security. Added compression to my metal 3D printer slicer exported CAM files, and refactored the code to better support larger volumes. Tweaking the piezoelectric driver PCB design for the micro-positing microscopy stage project. The Nanomotion piezoelectric motors were not meant to be used in the manner I chose, but it is fun to push the limits of technology. Finishing up some custom 1U mounted hardware, and getting a batch of test PCB soon. Bend radius came back 1mm oversize, but this was acceptable for a single run item. Also involved in several other projects maybe 3 people would care about. Doing a custom FPGA PCB is not very fun unless encountering that rare class of problem CPU/MCU simply can't handle cleanly. =3 I've been building SageNet, a voice-first AI coach that turns your goals into structured, adaptive learning plans. After a 2-minute voice conversation, Sage generates a personalized 6-module roadmap with build-first projects. It checks in by voice, analyzes your reflections, and regenerates your plan if needed. You can invite friends to your Support Squad for accountability. The biggest insight so far is people don’t want “infinite content.” They want structure and someone who remembers them. would love feedback! For fun have been creating a mashup of old school DnD map generation using Commodore "10 Print Chr$(205.5+Rnd(1)); : Goto 10" style logic (in TS/Svelte/SVG): Have been down a rabbit hole ensuring the stairs are realistic and that grid connects properly. Lots of fun and frustration with AI coding tools trying to solve that (they mostly don't/can't). Some fun detours learning a little Prolog to help out as well. Here’s mine: I’m building a small live NFL game-prediction tracker and writing up what I learn as I go: https://michellepellon.com/portfolio/nfl-game-predictions # What’s under the hood today ELO translated to the NFL with margin-of-victory adjustments, a modest home-field term, and week-to-week recency weighting. Post-hoc calibration with isotonic regression so 70% predictions land near 0.70 empirically. Monte Carlo to roll games forward for distributions on weekly win odds and season outcomes, plus basic reliability/Brier/log-loss tracking. # Where I’m taking it (ensemble ideas) Blend a few complementary signals: (1) pure ELO strength; (2) schedule-adjusted EPA/Success Rate features; (3) injury/QB continuity and rest/travel effects; (4) a small “market prior” from closing lines; (5) weather/play style pace features. Combine via a simple stacked model (regularized logistic, isotonic on top), or a Bayesian hierarchical model that lets team effects evolve with partial pooling. Separate models for win prob vs. expected margin, then reconcile with a consistent link so the two don’t disagree. Emphasis on calibration over leaderboard-chasing: reliability diagrams, ECE, PIT histograms, and backtests that penalize regime drift. # Why I’m doing it It’s a sandbox to teach myself Monte Carlo and ELO end-to-end—data ingest → feature plumbing → simulation → calibration → eval—on a domain with immediate feedback every week. # How this connects to my day job (healthcare ops) I work at BlueSprig, running ~150 ABA therapy clinics. I’m exploring whether ELO-like ideas can augment ops decisions: “Strength” ratings for clinics, care teams, or scheduling templates based on outcome deltas and throughput (margin-of-victory ≈ effect size/efficiency). Opponent/schedule ≈ case-mix, payer mix, staffing constraints, geography. Monte Carlo for expansion planning (new-site ramp curves), capacity/OT forecasting, and risk-adjusted outcome monitoring with calibration so probabilities mean something. Guardrails for fairness and interpretability so ratings don’t become blunt scorecards. # Help If you’ve shipped calibrated ensembles in sports or have pointers on applying rating systems to multi-site healthcare operations, I’d love to trade notes or if you need someone to this and other kind of work for their dayjob email me at mgracepellon@gmail.com -- I would love to do this fulltime.
