Information Security is the day job. When I'm not saving the world that way, I'm busy hacking on Linux. I've been fiddling around with Linux since 1993. I grew up building my own systems, but I like the simplicity of the Debian package system, and Ubuntu is my current favorite way to realize that.
The second time you have to do something, you should write a script to do it for you.
In the Ubuntu world, my interests are security (naturally), the automation of systems administration, and unique builds like embedded systems, multi-boot USB, encrypted thumb drives, etc. That said, I'll jump into any topic that seems interesting enough.
