uv: An extremely fast Python package and project manager, written in Rust

uv and ruff are a great counterexample to all those people who say "never reinvent the wheel". Don't ever do it just for the sake of doing it, but if you have focused goals you can sometimes produce a product that's an order of magnitude better.

They didn't reinvent the wheel, "just" replaced all the wood with more durable materials to make it handle rotation at 10 times the speed

I'd be curious to know exactly what changed. Python -> Rust won't make network downloads faster nor file I/O faster. My naive guess is that all the speed comes from choosing better algorithms and/or parallelizing things. Not from Python vs Rust (though if it's hard to parallelize in Python and easy in rust that would certainly make a difference)
