It's been really exciting collaborating with the rust-analyzer folks on salsa (which we use internally in ty)! A lot of the improvements end up making their way into both projects, I think salsa has a bright future ahead.

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.)

I was recently made aware that every single additional *cycle* in the hash function used by rustc increases its runtime by a whopping 0.25%

No I don't want AI generated PRs on my repository thank you very much

Going to try and publish more than one blog post this year...

Nice to see people experimenting with alternative scheduling algorithms! nurmohammed840.github.io/posts/announ...

I think all the talk about async being hard somewhat misses the point that high-throughput low-latency systems *are* hard, and the people building those systems are also the people developing and maintaining the async ecosystem.

The next version of papaya reaches over 2x the read throughput of dashmap!

I guess it's time to start cross posting here.
