As I mentioned in a previous post, I now have a GitHub account; all of my small code samples will be hosted there as gists, bigger functions will be added to my "poshsite" repository, and bigger projects will get their own repositories. I've removed all of the directly embedded code from this site and converted them to gists; this will give me a better place to store and share my code, and it provides much better syntax highlighting than what I was previously using.
That's not even getting in to the fact that it tracks changes for me automatically.
Anyway, you can find me at https://github.com/poshcodebear, and my gists at https://gist.github.com/poshcodebear.
