I'm a security guy now. I used to be a DevOps-ish guy. Before that I was a Linux guy. I've also been a Windows guy, a network guy, a Help Desk guy, and a soldier guy.
I like your stereotypical geeky things, like gaming and astrophysics. I also like some not-so-geeky things, like skydiving. I still don't like spectator sports.
I tend to run my life as a series of obsessions. Some stick around after I find new things, and some just fall to the wayside.
