I have two blogs [0][1]. For my main blog I use a Perl script that's far from ready for public release. For the tumblelog [1] I wrote a static site generator [2] that's available via GitHub
On the main blog I write about technical stuff, and solutions. The tumblelog is mostly links to interesting things I've read on the Internet with now and then short book reviews and some photos I have taken.
