I'm excited to share / launch an early preview of diffui.ai.
Diffui takes a different approach to AI design, leveraging diffusion as the first step. Take it for a spin - I'd love your thoughts.

Claude Code is great at "duct tape" build systems and refactor work. Here's an example, commit link below.
Input: Could we compile quickjs libregexp to wasm, call it via wazero, and use it as a replacement for regexp2 which can actually handle some of the unicode edge cases?

I wrote a JS Engine in Go using Claude Code. This has been my side project for the past two months.
It's passing ~44000 Test262 tests, almost reaching parity with QuickJS on Test262.
The code is available on Github (MIT License), and I wrote a short blog about it.

A new Signals and Threads just dropped, with @ianthehenry! This one is about building tools for traders, but it also has some fun dives into Ian's personal projects, including bauble.studio and janet.guide/.
Anyway, more here:

Every JIT tier is now enabled on the Windows port of JavaScriptCore. Big thanks to @Constellation who had the great idea of using sysv_abi in the first place, and reviewed the bulk of this work. Read more about it here:

With @iangrunert 's change, now JavaScriptCore first ever enables FTL JIT on Windows. The key thing is it is not achieved by adding massive Windows-only weirdness on JIT! (cont'd)

This PR by @iangrunert is an important step towards making JavaScriptCore on Windows as fast as on macOS & Linux
