Last thing I was working on was Dennis MUD, and before that Driftwood. I haven't had that programmer energy for three months now though, so I haven't been really working on any software projects. Usually I get interested in programming for about a month and that comes in 2 month or 6 month cycles, or somewhere in-between.
Mostly I've just been maintaining the server, and I also set up a server and website for a roommate a while ago who got kicked off of Tumblr for lewd artwork.
If you want to learn a programming language I always recommend Python, but lately JS has become a good general-purpose option too thanks to NODE. My first language was actually FreeBASIC, followed by C. FreeBASIC has a lot of cool old hobbyist games.
It's also good to know HTML and CSS so you can make your own websites. I probably end up using HTML more than anything else. You could also learn Linux so that you can host your websites and whatever services you want on a server you run yourself.
