I run Linux as an operating system on my computers, so I thought I might share a few links that have helped me in the past.
- Ubuntu - the main distro that I use; very nice for beginners, but customizable enough for more advanced users
- Run Linux from a pen drive - now you can have Linux whatever computer you work on! I have two different distros: a DSL boot from an old 128mb usb drive, and a qemu persistent SLAX on a 1gb usb drive
- Slashdot, a great source of all sorts of geeky news (including Linux)
- LaTeX Project Homepage - where it all begins, including downloads for all operating systems
- LaTeX Wikibook - great source of information
- LaTeX Beamer Class - the best way, in my opinion, to give a presentation
- Math into LaTeX by George Gratzer - my favorite reference book when it comes to LaTeX. I would suggest buying a copy (ISBN0817641319), but I have also found a shortened pdf version online.
