Description

Change is challenging but quite often the tools that we used to solve yesterday's problems are unfit for tomorrow's problems. In this episode, Kris and Matt are joined by Rain Paharia, one of Matt's colleagues at Oxide who is also the creator of cargo-nextest. The trio discuss version control, the most difficult problem of Rain's career, and the challenge of rigor in an age when it's becoming cheaper than ever.

Rain brings their knowledge from a decade at Meta to our ongoing discussion of jj, git, and why version control systems are so much better at the big tech companies. The trio discusses their gripes with GitHub, including some fresh perspectives from Rain on GitHub's attempts to fix issues (including some awkwardness with how Stacked PRs actually work). Then the conversation shifts to discussing how the team at Oxide managed to create an incremental updating system that works on air-gapped racks with hundreds of components. Along the way the trio also discuss API versioning and property based testing.

You might be wondering where Kris' voice is in this episode? Well, he can certainly be heard in this weeks' supporter content! This week the expanded edition includes deep conversations about why LLMs got better at code but worse at prose, why Rain doesn't allow LLMs to write comments, LLMs as cliche machines, and some discussion of our favorite topic, Go modules.
