Linux Baby Rocker -- inventive use of a CD drive and the eject command ... (via Hacker News) I Like Unicorn Because It's Unix -- forceful rant about the need to rediscover Unix systems programming.

October 7, 2009

On that Friday, with no warning, the little netbook failed to boot up. I couldn't even get to the BIOS. For the third time a Sylvania netbook I owned had suffered a premature hardware failure.
