Australia's LinuxChix unite to form AussieChix

Melissa Draper
LinuxChix, a social networking group for women who use Linux and other open source software, was formed in 1999 by Deb Richardson, a Linux user who was frustrated by the attitudes of many other Linux-oriented groups. Since then, the organisation has grown dramatically, and there are currently more than 40 regional LinuxChix chapters around the world. Until February, LinuxChix had chapters in Australia in Melbourne and Sydney. Following discussions at the Linux.Conf.Au conference in Sydney in January, members realised that a national group would better serve the country. Last month the groups united to form AussieChix, a new nationwide chapter that makes the group more accommodating to women from across Australia, whilst also improving the communications between the members of the previous chapters.

Might be the husband of Rachel Probert. I was flipping through my co-worker Josh's copy of Linux User magazine, reading an article about the Fish shell, when I flipped forward and caught her article (and picture) at the end of the magazine. Ok, dude, how did you find a woman that looks like that and digs Linux? My bet is that he went all Weird Science and made her! Any advice for a punk rock loving, El Camino (with flames on it) driving, Linux loving guy like me?

midnight maintenance

Another weekend gone. I'm "on call" this week, so I've sort of had to stay availabe (which, for the most part, meant staying at home). To that end, I finally got my house wired up. I terminated the end of the Cat5e in the low-voltage panel with RJ-45 connectors, and hooked them into a switch. My low voltage wiring panel has a electrical socket in it, so powering the switch is no big deal. I have Cat 5e connections in each bedroom, one in the loft, two in the family room, and one in the kitchen...so I can get pretty networked. I hooked up my laptop, and it made me realize how much nicer a wired connection still is. Wireless works, but even with my iBook, I've always had little dead spots, requiring me to position either myself or the computer in weird ways to get a good signal. Not to mention that I think many wireless chipsets are taking a step backward in usability, at least as far as Linux is concerned.
