Show HN: An 8-bit live gamecast for baseball

Hey HN, I built a website to watch live baseball games in an 8-bit broadcast. It takes live MLB data streams and converts them into near real-time pixel art gamecasts. Been waiting to share this for when there’s actually a good slate of games happening since the site is pretty bare otherwise. Here is today's schedule: Mets @ Reds - 9:40am PDT https://ribbie.tv/watch/game/824503 Royals @ Nationals - 10:05am PDT https://ribbie.tv/watch/game/822721 Marlins @ Phillies - 10:05am PDT https://ribbie.tv

We’re building CADAM, an open source Text to CAD platform. It's a React app (TanStack Start) with a Supabase backend for auth, database, and file storage. T

Show HN: In-browser Python/Pandas/Git practice with animated Git simulator

I've created an in-browser Python/Pandas/Git practice environment for my online learning platform and also for my corporate training classes. I'd be happy to discuss how I went about designing this, how I'm using it in my classes, and the architectural decisions I've made. Most interesting, to me, is how much is running in the browser. Thanks to Svelte, Pyodide, isomorphic-git, LightningFS, and CodeMirror I'm able to provide a full environment for Python, Pandas, and Git. I built much of this wi
