Two years of classes and work are over  and I have a Masters in Computer Science . They asked me what I focused in, but I'm not entirely sure. The classes I took fall into the Software Engineering category and also in the Programming Languages category. I think I ended up with a Masters in CS focusing on Programming Languages.
It was a fantastic experience and I'm twice as able as I used to be. I learned Scheme and SML, Adaptive programming and aspect-oriented programming, XML Schema and XPath 2.0 (to some degree), structure-shy development and compiler technology, operational semantics and denotational semantics (though I'm still kind of iffy on the denotational kind), functional programming and LaTeX, and I was able to go to a bunch of really neat seminars and hang out with a group of exceptional people.
I'm really glad I took the two years off to go back to school. I didn't expect it to pay off so greatly.
