Git is the version-control system developers use constantly — and talk about constantly. This episode builds the mental model and vocabulary that lets you follow those conversations without pretending.

- Git wasn't designed — it was built in a crisis, in two weeks, by Linus Torvalds after the Linux kernel lost its version-control tool overnight

- The five design goals Torvalds set in 2005 (speed, simplicity, distributed architecture, parallel branching, large-scale efficiency) explain every quirk Git still has today

- The one idea that unlocks everything: Git stores snapshots, not changes — every commit is a complete photograph of your project at that moment, not a list of edits

- That snapshot model is why Git can jump back to any point in history cleanly, without replaying a chain of changes that might break

- The episode covers core developer vocabulary — commits, branches, rebasing, PRs, git blame — explained the way a developer would over coffee, not the way a manual would

- Git also functions as an audit and security instrument, not just a collaboration tool — the episode explains why that matters outside engineering teams
