There's some gaps that have developed in my knowledge of T-SQL that I need to fill in. I'd like to work on that and also on re-learning VB as the last serious development that I did in VB would have been back in 1995 or so: it was GUI, but still just a tad bit outdated. My current project is reaching internal testing phase, so I expect some time to loosen up (hopeless optimist).
I bought a bunch of Arduino stuff when Radioshack closed their doors, that's something I want to spend some time on as I have some ideas for some art projects that I want to do, that'll also involve re-learning some basic electronics, which'd be cool.
I would really like to spend some time with Swift and work on some iOS development, but that's a long-range goal that I don't know when I'll get around to that. And with the rapid change in development for portable devices, it'll be completely changed by the time that I get around to it. I'm tempted to dig in to Python and PostgreSQL to see if I could get involved in IT at the observatory that my wife works at, but it's not much of a temptation. It'd be cool, but I really don't have the science background.
