Rust coreutils with Sylvestre Ledru

Josh talks to Sylvestre Ledru about the Rust coreutils project. We've been using GNU coreutils for decades now, and the goal of Rust coreutils is to rewrite these utilities in Rust. The primary reason isn't security, it's to modernize the code and attract new contributors. Sylvestre discusses with quite pleasant relationship with the GNU coreutils developers, some of the challenges in the project. What Ubuntu using this by default meant, and also gives us some things to watch for in the future. It's a super fun discussion about why Rust is not only awesome, but also the future.
