Logbot (Oct 01 2025 at 19:30): Logbot (Oct 01 2025 at 19:30):Charlie Marsh built Ruff (an extremely fast Python linter written in Rust) and uv (an extremely fast Python package manager written in Rust) because he believes great tools can have an outsized impact. He believes it so much, in fact, that he started an entire company that builds next-gen Python tooling.
On this episode, Charlie joins us to tell us all about it: why Python, why Rust, how they make everything so fast, how they're starting to make money, what other products he's dreaming up, and more. :link: https://changelog.fm/660

Tim Uckun (Oct 05 2025 at 07:08):No mention of Mojo :)
Ron Waldon-Howe (Oct 05 2025 at 08:53):I wonder what language the Mojo compiler is written in?
Looks like it it's possible to integrate Rust code in a Mojo project :crab:
