Source Code Management (SCM) is one of those things that computer scientists and geeks love to talk about, and I think I've just worked out why! When you get a new SCM tool working, and the coin drops - it's awesome! It's like the most impressive Hello World ever. Previously I've used Concurrent Versions System (CVS), which is the only time I've actively collaborated on a software project, and when I started my PhD I used Subversion. I'm a follower of fashion when it comes to SCMs, and as you've probably seen, Git has been spotted all over the internet. So I thought I'd investigate, and this is what I've discovered after using it for around 3 months.
