A place to document tips and tricks for the various Linux, LaTeX, OCaml, and other general computer-related topics that I encounter in my daily life and a repository for supposedly amusing observations, hyperlinks, recipes, reviews, travelogues, and political opinions written when I have a spare moment (or when I don't have a spare moment, but I don't feel like working)Contact: Chris
