Jon Seager, VP of Engineering at Canonical and I had a discussion about using Rust in Ubuntu. 🦀 🎙️ Jon is super honest about the tradeoffs of the migration (we cover uutils and sudo-rs) as well as future projects. We also touch on the costs of legacy software in C. Podcast here: https://corrode.dev/podcast/s05e05-canonical/ Thanks @[email protected]! #rustlang #rust #podcast
