Join us on March 18 for Localhost!

The RCade is a custom arcade cabinet built during the Fall 2, 2025 batch at the Recurse Center. It has a real CRT, a custom graphics card, spinner controllers, and a deploy pipeline where anyone can ship a game just by pushing to GitHub. It now has over 44 games.

Frank Chiarulli (@_fcjr), Rose Hall, Stephen Downward, and Greg Sadetsky (@technology_greg) will present how they built it; reviving the hardware and building the deployment system, designing a custom display adapter from scratch, and building a game engine and plugin sandbox.

Full-stack Go + SPA with:

→ HMR
→ E2E type safety via a vite-plugin
→ OpenAPI built in
→ Built on go std lib

I've wanted this stack for years. Got sick this weekend and finally finished building it.

Still early stages — would love feedback:

LLMs are even cooler if you use them kinda wrong... achieving near optimal compression with a 360M parameter model:

Frank: What do you think about making a cabinet using a CRT monitor?

Me: I don’t know anyone who uses CRTs, but I couldn’t tell you why.

@kshitijHash @_buildspace That's awesome! Have you made a browser extension before? If not I'd check out crxjs, super great starting point https://t.co/Uo8RRMxNrL

I've noticed a lot of US copy editors, especially in the news business, reflexively remove all commas except for those that are grammatically necessary. Is there a reason for this? Can't a comma just be a pause, an aid for readability and subvocalization?
