I am CO2 and I code. After starting with TI-Basic on my TI-83+ calculator in high school, the first "serious" language I used was Java. Since then, I've grown fond of functional programming languages, specifically Scala.
If you want to get in touch, I can usually be found on SlashNET IRC, in #xkcd-coding.
