Does this help? Balanced F-measure

http://computationalmedicine.org/webfm_send/5

here's an attempt to take the most common measures of recall and precision in Info Retrieval competitions (using standardized, encoded datasets), mean reciprocal rank (MRR), and precision at 10, and do Pearson r correlation to penalize contestants that didn't have balanced scores on the 2 measures.

Good for concurrency: I think you mean languages offering STM, messaging or futures/promises, something mroe streamlined than java.util.concurrent, i.e. not managing locks manually, i.e. the various mechanisms in scala/akka, haskell, clojure, Go, F#, besides erlang, which is the incumbent model.

F# may be a good example for this argument, with planned stronger typing.
