Bitten by the snake

I got in an hour of study at lunch today. It started as some superficial reading on Markov Chains (no particular reason to choose that topic; just had to start somewhere). Half an hour in, I came across some code that computed Hidden Markov Chains in Python. I haven't written anything in Python in a very long time. I'd forgotten what a delightful little language it is. I spent the remaining half hour messing around with the code. Probably best not to get distracted like that, but it was fun and fun is good at this point.
