On Feb, 5 I attended DDD North. There were many excellent talks, but, in this post, I'm delving into something that I saw in one of the grok talks (I gave one myself). It concerns a feature of git that I'd never heard about until then, and it's proved to be enormously useful. This post is, as all of my posts are, really for myself.
You're giving the app a quick test, and suddenly you realize that something in the application has stopped working (or maybe it's started, but it shouldn't have). You remember that two days ago, this particular thing was working fine. This post is going to cover manually using git bisect to determine when your code was broken.
