Over 80% is running on some form of Linux – so does your Mac and you iPhone. Sometimes we have to get our hands dirty on the command line – it makes you feel like a proper hacker.

I deviated a little from both articles, so here’s the “remix” which should work specifically for the Samsung NC10. I’m running CentOS 6.5 in 32bit, minimal installation without any bells or whistles, on a 1GB Intel Atom machine.
