Avidemux is a free video editor and converter. It is not really designed for beginners but isn't too hard to get your head around with a little effort.

Avidemux is available for Linux, BSD, Microsoft Windows and Mac OS X (under x11) and is designed for simple cutting, filtering and encoding tasks. It supports many file types, including AVI, DVD compatible MPEG files and MP4.

Super User is a Q&A site for computer enthusiasts that's free. Free to ask questions, free to answer questions, free to read, free to index, built with plain old HTML, no fake rot13 text on the home page, no scammy google-cloaking tactics, no salespeople, no JavaScript windows dropping down in front of the answer asking for $12.95 to go away. You can register if you want to collect karma and win valuable flair that will appear next to your name, but otherwise, it's just free. And fast. Very, very fast.

Notas de configuração, dicas e truques. Interessante para iniciantes no sistema, como eu, por exemplo.
