Nice slides. You should check out https://github.com/twitter/algebird https://github.com/twitter/algebird - we've implemented a number of streaming algorithms (HyperLogLog, Count Min Sketch, along with stuff like minhash and bloom filters) in Scala as Monoid typeclasses. Love to hear your thoughts or get your contributions.
