This site is created using a set of Python scripts that I wrote. About a year ago I got tired of MovableType and wrote a simple script to generate blog pages from a MovableType archive file. I had also written a separate script to generate pages displaying a selection of photos. This year I added scripts to generate Gallery-like pages for all albums, integrated everything and added a shared set of categories. I've been thinking of opening the code, but it was too messy. This past weekend I finally got around to clean it up enough that someone else might realistically be able to use it.
The project has it’s own page: Jatobá – Photoblogging for Nerds.
