I'm a linguist, so all of the programming that I slog may way through has to do with language or linguistics in one way or another.
I've been programming for a long time but I still feel like I've got a long way to go. But maybe that's how I should feel. :)
I'm a big believer in the idea that just a little technical skill can be very useful for people in many fields. So I spend a fair amount of time trying to explain things like HTML and CSS and perhaps a little Python or something to other people.
If anyone out there is interested in working on open source projects for linguistics, please get in touch.
I have a Github account but it's a bewildering pile of crap right now, I'll try to get around to cleaning that up and then I'll post it here.
