I've been teaching Git for years, and everywhere I go `git bisect` seems to be a bit of a mythical beast. Some people have heard of it, very few know what it is, and almost nobody knows how powerful it can really be.

In this short talk, you'll find out not only what bisect is and how it works, but also all the ways in which it can work for you. From finding a specific point in your history lightning fast, to making it debug for you using a combination of bisect and regression testing.
