It's the little things...

New toothbrush! The bristles are just bristlier.

Also: the mighty Zach G yourusername came to ATLhack tonight. He brought up Fermat's Little Theorem and probabilistic tests for primality, which, to be honest, I hadn't thought about a lot, but reveal all sorts of math I'm going to have to go and learn. Mark and I tried to give him a basic overview of classification and supervised learning. Later, in our discussion of clever ways to lay out the datastructures for the Scrabblebot, we ended up finding out, from the mighty Joe and Erik and Tejus (shared journal: yourusername), that postgres lets you have multiple indexings on the same table, which somehow lets you optimize your lookups based on what you're looking up? This has to do with the fantastic world of query optimization, which I should really learn about -- if you're a database, given a particular question, how can you find a logically equivalent question that can be answered more efficiently? (rockstarling, you've spent some time thinking about this, yes?)

There is so much to learn in the world... (also: woo for invigorating ATLhacks!)

Not much, actually! I have some other pet problems.

Those are some pretty awesome pet problems to have. Useful heterogeneous data sources ahoy(?) !
