Here are a couple of links I'd like to share.

Interesting and useful links:

LinuxChix, an organization for women who like Linux and open source
Wikipedia, the open-content encyclopedia
Stack, the university computer club I've been a board member of
CodeYard, an Open Source organization for high school students (in Dutch)


Fun links:

xkcd, a webcomic of romance, sarcasm, math and language
Ikariam, a browser game
GeoCaching, for those of us who like to geek and go outside
