GitHub is an amazing tool which holds a lot of promise for pushing open source software development forward. I say that because they make the process of forking someone else’s repository and then merging your changes (with their permission, of course) back into the master repo as simple as a few mouse clicks. I, for example, contributed a patch that made jQuery CSP-compatible which was later pulled into the jQuery trunk.
Since GitHub has become the industry standard for sharing code, I’ve started the process of moving all of my open source tools to a repository there. So far, I have only moved my Python CIDR block converter, but the rest should follow soon!
