Ghostling
Ghostling is a demo project meant to highlight a minimum functional terminal built on the libghostty C API in a single C file. The example uses Raylib for windowing and rendering. It is single-threaded (although libghostty-vt supports threading) and uses a 2D graphics renderer instead of a direct GPU renderer like the primary Ghostty GUI. […]
Show HN: We built a terminal-only Bluesky / AT Proto client written in Fortran
Yes, that Fortran. A terminal-only Bluesky / AT Protocol client written in Fortran, with a Rust native firehose decoder for the relay-raw stream path.

We rewrote our Rust WASM Parser in TypeScript – and it got 3x Faster
We built the openui-lang parser in Rust and compiled it to WASM. The logic was sound: Rust is fast, WASM gives you near-native speed in the browser, and our parser is a reasonably complex multi-stage pipeline. Why wouldn’t you want that in Rust? Turns out we were optimising the wrong thing. The openui-lang parser converts […]
Discontinuation and reinitiation of dual-labeled GLP-1 receptor agonists

Featured Video What happens when you stop taking them, though? We know the weight tends to return, but research […]

BIO: The Bao I/O Coprocessor
BIO is the I/O co-processor in the Baochip-1x, a mostly open source 22nm SoC I helped design. You can read more about the Baochip-1x’s background here, or pick up an evaluation board at Crowd Supply. In this post, I’ll talk about the origins of the BIO, starting by working through a detailed study of the […]
