Installed my first Linux system, which was Slackware, in the summer of 1995. Then that fall I wiped root and installed the new version of Slackware. Then that winter I wiped root and installed Debian. I've stuck with Debian ever since.
Most of my programming is in Perl and PHP. I rarely do bash or sh scripting any more, unless it's a startup script or a really simple quick-and-dirty script. I've spent some time on Common Lisp, but haven't used it in many projects yet. I do use it in a couple of places for HTML generation, but that's about it. My current hobby programming language is Erlang, but I haven't done much with it yet.
Currently, I'm part of a team that admins ~600 servers. We're a 24/7 production shop. I'm third-tier support, and am on-call except when I'm in a theater. Because we stream audio and video for customers around the world, it's important to have a fast response to any customer issue, no matter when it happens.
