It's only been recently that our version control systems have matured to a point where we have the freedom to think about how to collaborate with our colleagues. But we still make mistakes and suffer through bad life decisions. "Bollocks!" you might say.

Well, when was the last time you heard something like this?

• "Version Control, you say? never heard of it"
• "uh, what version am I supposed to be working from?"
• "we don't use branches, they just get in the way"
• "we're going to gate your checkins and review them"
• "don't worry about it, just hit that merge button"

Git Black Belt Edition

Are you using Git via the command line? Want to learn some tricks or understand more about what Git is actually doing under the hood? This will be mostly live demos, because it's so much more fun to see this stuff in action.

I'd also like to make this session interactive - if you've got questions about Git you'd like to see answered, please file an issue here and I'll see if I can work the best ones into the talk: https://github.com/shiftkey/talks
