Our guest today is James Coglan. James has written an extraordinary programming book called Building Git. In it, he describes the inner workings of the Git source control tool by re-implementing a substantial part it in Ruby, including commits, diffs, branching, and networking. Along the way he shows not just how Git works, but also details of some of the algorithms it uses. There’s also a lot about building complex systems generally. And it has some great examples of test-driven development. James and I also talk about implementing in a high-level language like Ruby, versus a lower-level language like C. It’s a unique book, and I’ve been looking forward to talking to James about it for some time.
