Last year I ran the well received (and fun) LinuxChix miniconf at linux.conf.au 2007 which spawned AussieChix among other things. Melissa Draper is running a second LinuxChix miniconf at linux.conf.au 2008 (January in Melbourne). Melissa has the website up and the Call For Presentations out (closing October 15). Be excited, be very excited!
Another women-in-computing event currently has a Call For Participation in circulation: the Women in Open Source event at SCALE, February 8–10, 2008, Los Angeles (CFP, closes 30th November).
A women’s unconference is also coming up: She’sGeeky, October 22–23 2007, Mountain View, California. If you dig a little though you’ll find that there’s a USD125 registration fee though which is high for an unconference.
