was what I've been hearing for some time from quants. Recent graduate here, trying to decide which "ecosystem" to focus on for quant-like places. What do you people thin, which one is the most frequently used, JVM or .NET at the financial industry? JVM would include all languages running on it, like Java, Scala, Clojure, etc., while .NET the ones like C# and F#. Any personal views would be appreciated.
