About the show

Hear all about functional programming in practice. We invite people working on hard industry problems to tell us how they are solving them, the tools they use, and what gets them up in the morning. Expect deep dives into Haskell, Nix, Rust, build systems, data engineering, AI, and more. We make it back to the surface too sometimes, to chat about engineering culture and the challenges of leadership in distributed teams.
