I started using a gitit wiki to maintain my notes on CS research and programming. It’s available here. For a while, I’ve kept my notes in a bunch of “loosely pandoc” files, so gitit was an easy way to wiki-fy everything—to make them easier to view/edit from any browser, and to share publicly.
At the moment my notes are highly disorganized and probably have many formatting bugs. Also, they typically don’t include topics from classes I’ve taken. I’m hoping this will become a not-too-cryptic way for me to share more information with less effort than writing blog posts.
