I decided to learn Git. Our file hosting over at Hackaday.com has been hosed for a while and I wanted a good place to host code. I knew that Adafruit and others use Github. I had looked into that and bitbucket a while ago but I've never really been pleased with subversion when it came to merging and resolving conflicts. So I found a guide over at Stack Overflow that is pretty handy. I read through the commands and got myself setup, committing my code to a repository and all that jazz. But it wasn't until I got to the bottom of that guide that I found out about Understanding Git conceptually. Wow! Fantastic. Not only is it very well written, but when you understand what Git is actually doing you can begin to see how truly brilliant it is.
