I spent a good chunk of the day working on writing up the rules for a boardgame I'm developing (a Civilization/Master of [Orion|Magic]/4X-style game with bugs), and I'm pretty satisfied with what I accomplished.
It was rainy and cool off and on, and Greg baked a lasagna.
My work computer churned out 16,000 runs of the game this weekend, so I had enough data to figure out how to balance the hazard scores properly today. Got a bunch of stuff tweaked, left it running more for tomorrow so I can compare the changes.
I did lots of probability calculations today. Probability is such a useful thing to understand, and important to so many disciplines, that I'm surprised it's not taught more widely in highschool. I'm really glad I took Prof. Rota's probability course my senior year at MIT. (Although, most of the other students seemed to have had at least a little bit of exposure to it, so maybe it's just my secondary education that was totally lacking.)
Today's I-hate-java rant: whoever thought that we still needed to have both floats and doubles as a core part of the language needs to be beaten with a stick. There should be integers and non-integer numbers, and if anybody needs something more complicated, they should use a special package that lets them decide how many bytes of memory to use to represent each number. Compiler errors that claim no matching signature could be found because "0.2" is a double and not a float fill me with homicidal rage.
