I'm an aged (over 30) OS enthusiast. Previously, as a developer in a small work group, I became the sysadmin by default since I was the only developer with a dozen users in a growing AIX environment.

Early Linux adopter, installing Slackware with 30+ floppies. I've installed most variants of Unix, Linux, Plan9, mkLinux, NeXtSTEP 486, BSD/386, NetBSD, FreeBSD, and I'm still waiting on HURD :)

Using Windows I am limited by Windows.
In Unix, I'm limited by my knowledge of Unix

My OS mantra is "learn something new each day",
a command, a config setting, an application, and day by day become a better user.
