The first I call "All these MySQL forks. WTF?!", giving some history and background and direction and impressions on MySQL mainline development, the Percona tree, the OurDelta effort, and of course Drizzle.
The second I call "Why distributed source control rocks!", talking about the workflow of git/bzr/hg compared and contrasted with p4/svn.
It was fun. And I had some ideas for bzr (that can also work for git and hg) that I will mention in a later post.
