Rasmus Lerdorf - latest rockstar of the computing world that I have met
I met Rasmus Lerdorf, creator of PHP, last Friday and discovered he took Systems Design Engineering at Waterloo just like I did (he's class of 1993, I am class of 1988). Very cool.
So now, I have met the following rockstars: Douglas Engelbart, Dave Winer, and Rasmus. Still to go: Linus Torvalds and the MySQL people.
