I recently brought Infocom's original UNIX z-machine source code back to life on modern systems. The modified source code, instructions on usage, a build of the z-machine, and examples of embedded game executables are available. There is also a detailed write-up about the state of the original source code, the porting process, and the invaluable role Justine Tunney's Cosmpolitan project played in bringing the Zork trilogy (and more) to Windows/Mac/Linux/bsd for arm/x86 machines over the course of a lazy Sunday.

Do you remember the internet of the early 2000s? Neat single function websites that let you be creative and customize your spaces and weren't setting out to be the next major conglomerate (or to be bought by them). I'm building a series of websites that have simple concepts but too many of the players have tried to make their product so big. I also used to live in a very rural area so my goal is to make websites that load fast even on very slow internet. I'm starting with Lynx.boo. A linktree style website that lets you fully customize your CSS (and adds a bunch of classes to your links to…

Viberia▲146Hey HN, This is my take on the agent harness. Everything on an isometric map. Agents are grouped into "buildings" that run in a sequence or a loop; e.g., the CodeForge has an agent that writes a PRD, another one that implements, and a third that reviews. Everything is customizable, you build your own buildings/teams however you want. It's a Tauri app, really light (about 8x less energy than the closest competitor I benchmarked, so it actually runs from a coffee shop on battery). It's macOS only for now, but ping me if you are willing to test the Windows or Linux version. I've been…

Hey all! Super excited to share this! If you're familiar with the r/InternetIsBeautiful sub-reddit, then you'll enjoy this. I built the website as a fun side project project over the weekend, and it re-imagines what r/internetisbeautiful would be if it was a newsletter. It's meant to be a completely free and community generated resource of the most interesting, useful and awesome websites from the depths of the internet. The list is tiny right now and I would love to hear your recommendations of websites that you think we should include. Hope you enjoy it, and would love to hear…

Hey HN, A buddy and I have been working on a side project in the online community space in our free time over the past few years. Our platform is a sort of Discord/Reddit/Patreon hybrid. Decided to do a soft launch today in light of all the recent Reddit news. Community features: 1. Customizable discussion boards. Community owners can setup threaded discussion boards for different topics related to their niche. Say a user creates a community for a niche like "Cars", under that community they could create different discussion boards for sub categories like "Car-mods", "Car-photos",…

Hi HN, I spent 20 hours manually researching "best startup directories" for my last launch. Found outdated GitHub lists, dead links, and no data on which directories actually matter. So I built this instead. *Live*: https://awesome-directories.com *GitHub*: https://github.com/awesome-directories/awesome-directories *What It Is* An open-source aggregator of 300+ verified launch directories with: - Domain Rating scores (Ahrefs), dofollow/nofollow badges, pricing filters - Community voting, favorites, and submission tracking per project - CSV export and…

This was an interesting porting project for a few reasons (IMO): - The original game is/was awesome and, from a programming perspective, a wonder -- smooth scrolling arcade game on a 128kb Mac in 1984... - The port was done with a lot of help from AI (mostly Claude Code, but some Gemini CLI as well). I'm a programmer; it wasn't vibe-coded. But I couldn't have done the port of 68k assembly without it. FWIW, Claude seemed better at actually porting the 68k assembly but Gemini was better at finding bugs. YMMV. - I love Redux and Redux Toolkit for state management. For the port, I put the…

Hey HN, I've been wanting to start this project for a long time, ever since I read an article about collaborative transformation of blob images[1], and I'm hoping it will take off here as I'm curious to see how it can grow. Here's how it works: - My website is available at https://chaospixels.com. You can find its code in the `src` directory of the linked repository. - Every day, I'll review all the open PRs (Pull Requests) and calculate a PR score based on the number of thumbs-up on the PR's opening comment. - The PR with the highest score will be merged and deployed. - Afterward,…

I didn't realize Universe Sandbox ran on MacOS, and I was in the mood to play around a bit. Some functions it's got: - Random system generation - Sonification is super fun too - Habitability Simulation (Just for fun, don't cite this please) - Replacing, spawning, deleting objects I've had tons of fun building this, so I hope someone else can share the joy. It's free and runs in the browser. I'd love to hear any feedback. I think this is at a state where I might leave it as it is, but if people are interested in other features, maybe I'll keep working on it. I've kept saying I'll stop working…

Hey HN. We've been working on a community platform/Reddit alternative with a focus on building a place for people to create communities instead of just buckets of posts. We want communities to feel like a place where you want to hang out instead of just scroll. At a high level, our platform is like a Reddit/Discord/Patreon hybrid. We took all of the best features from each of those platforms and combined them under one umbrella. Here's a list of the core features of each community: 1. Customizable discussion boards: Community owners can set up threaded discussion boards for…

www.schmeebs.com I built this site in two days. I tried to make it a fusion of Twitter + Digg in that people will be able to follow certain "domains" of news then be able to see popular stuff from there. Its as real time as it can be at this point. Would welcome any thoughts on it!

This was submitted before but it didn't seem to get much attention because I don't think the title was very descriptive and the submitter was brand new. I almost didn't click it but once I did I thought the project was pretty awesome and had a lot of promise. Hope this doesn't violate the rules, I have no horse in the game, but the creator is here on the site so hopefully he'll be able to answer your questions.

I spent the past few weeks making an open source cloud code editing environment with an AI copilot and multiplayer collaboration! It's fully self-hostable in 5-10 minutes. There's a lot of minor improvements to be made, and some are already listed in the Github issues. Let me know what you think and feel free to try it out.

I built a minimal opensource CMS, I use it myself for my blog and for other SaaS. l love blogging, and sometimes I post random thoughts on my blog. The only thing is, I always did it with .md files, which is fine too However, I was excited about the idea of using a CMS that was very minimal and avoiding the option of connecting something like WordPress or other big platforms. Open source (if you want to fork it or contribute) and free to use (unless I see you have a million views haha). Star the repo if you like it!

If you guys are interested in high-quality food products please let me know what you think of my website prototype. 1)Do you understand immediately what the site is about? 2)Is it easy enough to understand how it works? 3)If ready to roll in your neighborhood would you be interested in subscribing to a service like this? I am in the process of getting a closed-beta off the ground in Brooklyn and I am really interested in all kinds of feedback about the idea, the design, UX. Thanks. http://www.the-local-kitchen.com

I was debating when to post this, but I've been using it locally in a variety of situations for several months and I think it's pretty stable (and usable!). There are more features I'd like to add, but I wanted to see if there was much interest before spending much more time on it right now.

A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!

For fun this Valentine's Day, a couple buddies and I decided to play around with the idea of digital Valentines. We cranked out the project in the month of January as a "nights & weekends" project. We'd love any feedback in general! Our next step is to figure a way to seed this in key communities, to see if it has any chance of taking off. The URL is www.1millionvalentines.com (or www.1MVS.com). Thanks!
