I got to listen to Tom, one of the cofounders of GitHub, do a presentation tonight in Boulder for the local Linux users group. He did a great job. One of the nice things about it is that it wasn't a high level pitch about the business model or about what GitHub was. Instead, it was basically an introduction to the core architecture of git. How it works. How it's different than say CVS, or just keeping manual backup copies of files around. He actually went into Terminal, wrote code, and essentially hand-crafted git storage files in a Ruby interpreter, in order to illustrate how git works internally, and how simple it is. It was great on two levels. One one level, it was very substantive for a crowd of Linux geeks, we eat that stuff up. And on another level the fact that he clearly understood this stuff and enjoyed it and gets his fingers dirty actually building things. If I wasn't already firmly in the no-Ruby-for-me camp (prefer Python, and don't want to waste time switching time investments over to an approximately similar language), I'd probably love to work with them. Small companies rock. People that know their shit, and are passionate about it, rock.
