This week, the #python Software Foundation rejected a $1.5MM NSF grant, due to a requirement that the PSF abandon diversity work.
So I joined forces with Python folks (@offby1, @petrillic, @amethyst) and we're matching up to $12,000 of donations to the PSF. 🧵

Do you think the Gruffalo is lying to his child about the physical prowess of the big bad mouse or has he truly instilled a false memory in himself because he can’t accept the reality? This isn’t a take I guess but, makes you think

There's still a long way to go on this project, but I'm hugely excited about where we're going with this. Let's make Python typing even more awesome than it already is!
Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust.
In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)

So first: thank you to everyone that's contributed to ty over the past few months!

In the latest version of uv, we've updated the build system for our managed Python versions to use the latest LLVM version and cherry-picked an extra fix for a performance bug (github.com/llvm/llvm-pr...) and the early benchmarks are pretty exciting!
