Reinventing Python tooling with Rust (Interview)

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.
