Richard talks with Simon Lydell, a programmer whose open-source JavaScript work ended up contributing to what might be the most infamous package-related outage in programming history. In addition to talking about that story, they also talk about open source in general, breaking changes in general, and specific projects like CoffeeScript, Prettier, Elm, and Roc.

Richard talks to Will Kurt, an AI Engineer at Hex as well as the author of both the countbayesie.com blog as well as the book Get Programming with Haskell, from Manning Publications. They talk about the book, about Haskell in general, and end up comparing Haskell to R, as well as type systems and artificial intelligence!

Richard talks to Ayaz Hafiz about his work on the Roc programming language. They discuss behind-the-scenes compiler details like implementing ad-hoc polymorphism and defunctionalization using lambda sets. Along the way they get into how these implementation details interact with design of the language, and the experience of using the language.

Richard talks to Jakub Konka, a programmer who works on the Zig programming language. They talk about the low-level systems programming involved in Jacob's work on Zig and other projects, including things like disassembling binaries, hot code loading in a systems language, writing a linker from scratch, and testing machine code without access to the actual hardware - or even an emulator!

Richard talks to Chelsea Troy, a programmer working at Mozilla who has a side gig teaching Masters' Computer Science students at the University of Chicago. This is highly unusual, considering she does not have a computer science degree! They talk about how she landed that job, including how the interview process differs from industry interviews, among other topics.
