Various things going on. I'm putting a dual Xeon X5650 server together to raise the threshold of algorithms I could write that I would consider feasible. That's 12 cores with about 400% of the power of my desktop. Got a couple thousands pages of PDFs about history of programming and computation to study. Movies to watch, books to read, games to play. That means months before any possibility of making anything visible. New game designs keep stacking in my folder. But it's the path I've chosen because I believe it will pay off.
