I'm geeky enough to have a webpage about my computers. I have a number of computers running a number of operating systems.
Debian GNU/Linux: First and foremost, I think of myself as a Debian GNU/Linux geek. I first installed Debian in January 1998 and have been using it heavily (sometimes exclusively) ever since. I've run Debian on a number of my computers, including Debian PPC on four different Mac models. I admined Debian servers professionally from 1999-2005. I taught a Linux course based on Debian in spring 2001.
Ubuntu: Over the years, I've been favorably impressed with several Debian-based distributions for desktop systems. In February 2005, I installed Ubuntu, and I've been using it continuously since. I can sometimes be found answering questions on the Ubuntu Forums.
Mac OS X: Before I discovered Linux, I was a Mac geek. To a large extent I still am. I've owned more than half a dozen Macs, mostly laptops. I've used Macs (and before that Apples) for over 20 years. I like Apple ads, I think most of Apple's hardware is awesome, I've been to MacWorld, and I dressed up as imacgirl one year for Halloween (and no, you can't see the pictures). I think OS X rocks. I use it as I would any other Unix-like OS.
OpenBSD: I'm also a big fan of OpenBSD, which I've been running off and on for almost as long as Linux. OpenBSD is somewhat minimalist, very secure, has excellent documentation, mature routing/firewalling capabilities, and a cool-looking blowfish.
BeOS: BeOS is a thing of the past, but at one point I was a happy BeOS user. It was a great OS; I miss it some days. I still remember all the Be songs and have a (dual processor!) Be Box that I can't part with. Sad, but true.
Other OSes: I've run a lot of operating systems over the years. On personal computers, I've run Debian GNU/Linux, Ubuntu, Libranet, Xandros, Corel Linux, Stormix, and Progeny; RedHat, Fedora Core, and Mandrake; SuSE/SUSE, Gentoo, Slackware, TurboLinux, and Caldera; OpenBSD, FreeBSD, Solaris, and Minix; Mac OS X and MacOS/System 6-9; BeOS, OS/2, and DOS. I've also briefly used, admined, or supported Knoppix, AIX, HP-UX, Irix, NetBSD, NeXTStep, VMS, and Windows 95/98/NT/2000.
I've only used Windows to provide tech support, write documentation, etc. (Yes, really; I've almost completely avoided Windows. When I say I don't do Windows, I mean it.)
Active Personal Hardware (hardly any these days):
