With the New Year slowdown comes time to explore, and this year I'm revisiting 'version control'. I've used Subversion for a few years, but recent online chat is indicating a general move to Git. So I've been exploring Git, Github, Bitbucket and SourceTree to see how this all compares to Subversion. Git and Subversion approach version control in substantially different ways and the learning curve for Git looks steep. But it's exciting learning new tools - not least a tool as incredibly valuable, nay 'vital' for software developers - as version control.
