Last week I gave a talk at Helpshift about Bayesian analysis of conversion rates, A/B testing and Bandit Algorithms. The slides are hopefully self contained and might be useful for others. You can view them here.

I was recently introduced to the scalaz-stream library by the excellent blog post Actors are Overly Nondeterministic. I decided to take a look at them, and I realize they have a lot to offer.
