• Genotype: language that compiles to idiomatic TS, Rust and Python 0 open listings

  discussion=https://news.ycombinator.com/item?id=49617861, title=Show HN: Genotype: language that compiles to idiomatic TS, Rust and Python, Hey HN! I just shipped the first public version of a new programming language that I have worked on for the past two years. Its goal is to help synchronize types between TS, Rust, and Python (more to come). Two main use cases are the API client libraries and client-server interop, i.e., a TS web app talking to a Rust server. I focused on making it as flexible as possible but always produced idiomatic types that look and feel like they were carefully crafted by humans. It was a challenge, e.g., I had to test 7 Python versions for every language feature or had to implement Rust literals runtime. It's written in Rust, btw ;-)

• Gescom MiniDisc Runner 0 open listings

  discussion=https://news.ycombinator.com/item?id=49724628, title=Show HN: Gescom MiniDisc Runner – 88 tracks, 88! possible orders, NOTE: For a full backstory on this project, please see my blog post here which explains the absurd mathematics behind this unique music album. I hope you enjoy it! Blog Post: https://ei3lh.eu/2026/09/13/gescom-minidisc-and-mind-bogglin... Hello! I made a small Python program to solve a completely unnecessary problem: listening to Gescom's 1998 'MiniDisc' album in every possible order. The album has 88 pieces, which gives us: 88! = 1.8548264225739844 × 10^134 possible sequences. Obviously, making a playlist containing all of them would incur a slight storage problem! So instead, 'Gescom Runner' generates one 88-track M3U at a time, hands it to VLC (or player of your choice), waits for the playlist to finish, records where it got to, and generates the next permutation. It can resume after rebooting, jump directly to a particular permutation, and doesn't need to store the astronomical number of playlists. The complete journey would take approximately 2.37 × 10^130 years, so I'm reasonably confident nobody will be filing a completion report anytime soon! For transparency, I used AI and Wolfram to help write and document the code, and I've included that disclosure in the repository readme.md. The music isn't included — you provide your own legally obtained copy. GitHub: https://github.com/EI3LH/Gescom-MiniDisc-Runner I am no mathematician or hardcore developer, just a (very amateur) curious hobbyist, but I am particularly interested in whether there are interesting ways to improve the permutation generation, playback handling, or the general absurdity of the project. Thank you! EI3LH

• Give your AI agent on-screen guides that show users where to click 0 open listings

  discussion=https://news.ycombinator.com/item?id=49627872, title=Show HN: Give your AI agent on-screen guides that show users where to click, Hey HN. I'm Christian, one of the founders of Frigade (YC W23). I've noticed that a lot of in-app AI agents struggle to actually understand the products they exist in. For instance, let's say a user asks an agent how to do something in a given SaaS product. In an ideal case, maybe that agent replies saying it has a tool to do the task and just automates that work entirely for the user. That's a great outcome. But often that's not the case. Maybe there is no tool call for that exact task, or maybe the user's question is best solved by a specific UI workflow or interface. In these cases, many agents tend to fall back on basic RAG on their help center, or sometimes even searching the internet for an understanding of their own product. This can be a very slow process and most of the time help center articles are outdated as products evolve faster than them today. Even worse, no one likes reading a long list of bullets and mapping that back to a UI. My tool (Assist API) solves this gap with a single tool call defined like this: const frigade_guide_tool = {

• Give your AI agents access to WhatsApp 0 open listings

  discussion=https://news.ycombinator.com/item?id=49728159, title=Show HN: Give your AI agents access to WhatsApp, Hi, I built Chat-Man because I wanted a cheap way to give my agents access to WhatsApp without integrating a WhatsApp library separately in every project. You get WhatsApp MCP server, so you can connect WhatsApp to an agent and programmatically read, search, extract and send messages - but also have a web UI for non-techies. You can also receive webhooks for incoming messages for starred conversations. What you can do with the MCP? -Read WhatsApp messages and turn them into CRM records -Summarise conversations or groups -Extract structured information from messages -Find messages, participants or other WhatsApp data -Send messages -Manage group memberships Of course.. you always need to follow data protection regulation. The web UI: -Edit group details -See who joined or left -See who is most active -Export group members -Match members against a CSV (e.g. from a CRM) -Bulk message members -Bulk kick members -Create invite links For individual contacts, you can send messages directly from the UI. Why I built it for myself? I needed WhatsApp access for several projects (hermo.ai, florahaus.co.uk, …) and didn't want to pay for a WhatsApp integration for each project. Link: https://chat-man.net I’d love to get some feedback, especially from people building agents that need access to WhatsApp. Fabian

It turned into a package manager for macOS that uses Homebrew's bottle ecosystem, consistently ~2x faster than Homebrew on large install graphs. It's written in Rust, but most performance ideas are independent of the language.

• Godot and Rust based multiplexer (terminal panes and more) 0 open listings

  discussion=https://news.ycombinator.com/item?id=49660676, title=Show HN: Godot and Rust based multiplexer (terminal panes and more), I wanted to share my side-project: gPTY. Started off as an idea to combine Godot and Rust in a project (two stacks I wanted to use more to learn more). The base inspiration was tmux - simply allow spawning multiple PTYs and then let the user grid/tile them how they see fit. But since we have the Godot game engine at our disposal, we can do some more interesting things, like add an FPS counter, and then subsequently also let people set their preferred FPS (the idea being the potential lower power draw if someone's running it on a laptop on battery power vs someone running it on a desktop with high/native FPS). In its current state, with me using Oh-my-Pi a lot, it's evolving into a terminal workspace that can be used for orchestrating autonomous AI agents by way of dogfooding (or you know, just run herdr inside of gPTY - it's the better orchestrator and just good software - I found it after starting this project, and now I'm finding myself using it a lot). Also, we're not limited to just terminals. Since we have Godot, we have basically a 2D (and potentially a 3D) canvas to play with. We can already full-screen the app for "zen" mode, no taskbar, no distractions. TUI die-hards can have their media or other apps entirely in terminal panes. There has been some ground-work on getting Markdowns displayed properly done and I want to work on some kind of Wiki framework for local knowledge-management next, then create more types of panes (think native audio/video on a media pane, that sits alongside your terminal pane), and some simple 2D games (like snake) to prototype. More details are on the ROADMAP. What's not easy (and probably won't happen) is a browser. Having done a couple of (small) projects using Electron already, the temptation to ditch Godot/Rust (learning curve) did come up (and also the ecosystem, the ease with which I could pull components and use web technologies - development velocity would definitely be higher there). But on the flipside, given all of the available LLM and AI support that we are privileged to have today, I figured the velocity should be comparable depending on how much I leaned on those. And lean I did. Godot/Rust seemed the better call to me and my intent anyway - going with the 'it's not just the end but the journey that matters' philosophy. So yes, there has been heavy use of LLMs & AI to generate a lot of the code. But I do review and steer actively, not relying solely on vibes, and there's a few bits here & there that have been human authored. There are definitely a lot of polish and QoL items that need to land to make the end user experience better, but in the meantime, let me know your thoughts and/or concerns!

  discussion=https://news.ycombinator.com/item?id=49734856, title=Show HN: Hacker News, a little more focused, I love AI and LLMs as much as the next person, but sometimes I just want to browse stories about, say programming. So I built this for myself and figured I will share it here as well. Each story gets up to three tags, and I can use them to filter down the top stories to just the topics I am interested in. The tagging isn’t perfect. For example, some tags have a lot of overlap, like AI/ML and LLMs. But it works well enough for me and since it’s a side project, it doesn’t have to be perfect :)

• Halo 3's Guardian, playable in the browser, as my personal website 0 open listings

  discussion=https://news.ycombinator.com/item?id=49732259, title=Show HN: Halo 3's Guardian, playable in the browser, as my personal website, I've never had a personal website, and I didn't want to make a resume/portfolio site, so I rebuilt Guardian and hid a treasure hunt through my life inside it. You start in the Halo 3 main menu, go through the lobby, spawn in the map, and explore. There are photos, stories, quests, mini-games, and Easter eggs scattered around. Movement is via WASD and mouse, no signup. Guardian was my third place growing up. Starting in 9th grade, my friends and I would get home after school, get on Halo, and hang out in a Guardian free-for-all with MLG settings until everyone came online, then play customs or ranked for hours. On weekends we'd bring our Xboxes and monitors to each other's houses, stay up all night, and play in local tournaments. Guardian was probably the closest thing I had to a digital home, so I wanted my site to live there. Playing it and hearing the theme music for the first time in 10+ years in a place I knew by heart felt a bit like coming home. The map itself isn't AI-generated. It uses an original Guardian asset export distributed through the fan-run Halo Archive: an OBJ with 115,250 faces, the original UV coordinates, and 42 referenced diffuse textures, loaded through Three.js. What was AI-generated was everything on top needed to turn it into a complete game: shaders, lighting, scenario tags, physics, animations, collision, movement, sky and fog, lifts, pickups, weapon handling, and quest routing. Every pickup was placed by hand against the geometry using callout maps and a dev-only coordinate locator. This was surprisingly tedious to get right - I think it took me 10 iterations just to get the blue lift on Camo to line up parallel with the ledge. The Guardian geometry and texture assets are 21 MB, so the load is hidden inside the lobby countdown and scorecard screen while the shaders warm up. It targets 60 FPS and feels smooth on a recent MacBook in Chrome. Touch controls work on mobile, but the field of view is roughly 20 degrees in portrait, so desktop is definitely the best way to play it. I built it with Codex using Astra. It wrote essentially all of the code: 20,552 lines of TypeScript across 118 files, 973M tokens, 37 hours of runtime, and about 25-30 hours of my time. Coding wasn't the hard part. The time-consuming part was deciding which memories belonged in the map, where each should live, what game mechanic fit each one best, and then playing it over and over to fix bugs and get the movement and user flow to feel right. I'll write up more about the Codex/Astra side in a comment since I had a lot of interesting learnings from building something this large with it. This is an unofficial fan project and I'm not making money from it. The geometry, textures, UI, and many of the sound effects are Halo material and belong to their respective owners. Some things are still rough. There's occasional lag when picking up a power weapon. The lifts don't feel quite natural - it was hard to replicate the vacuum effect of the real lifts. On some browsers like Firefox, audio needs a click before it starts. Would love feedback on how it could be improved, especially from anyone else who spent a lot of time on this map.
