Using git bisect to quickly find the origin of a bug

git bisect is a really useful command for locating the origin commit of a bug or behavior. While surfing twitter I found a thread talking about bisecting in general and learned of the command and since then I've used it multiple times on the job to locate pesky bugs. I created a repository, blog post, and now a video to help spread the word about this mysterious little command.
