FreeBSD, enterprise open source stuff, network and system security. I wouldn't call myself an expert software developer these days, but I've been using PHP since 1995 and can find the bathroom on my own. Shell/awk/sed since the 1980s. My name here was my UUCP pathalias name, and is my nick on Freenode if you want to reach me there.

Oh, and #SOreadytohelp . :)
