Technical stuff

These are notes that I’ve been collecting over the time. Most of them are about Unix/Linux system administration, some of them are about Matlab, others about how to code efficiently with some programming languages like C/C++.

I’m also a fan of Latex and I enjoy producing beautifully typeset documents, here are some examples of latex typesetting, too.
