Hmmm... I could say it's only Perl, but like dc I tend to have Javascript, HTML, XML, SQL, Apache redirects, scripting, cron jobs, etc., as part of my output.

I have a BA in Sociology and psych; very few of my computer concepts came from formal schooling although one high school teacher really triggered me with a little assembler simulator named STOP for which we wrote programs on IBM punch cards. He actually explained register-indirect well enough that I was able to master the 8086. :)

What I did learn in (and around) college was how learning is creating associations and relationships, a way of growing that is the opposite of most formal classwork. Perl appeals to me because it is a very organically inspired language: it'll have sex with anything! ;-D
