Long time Java programmer who converted to Scala a few years back. I like building high performance systems built on top of Akka using other libraries like Unfiltered, Slick, Dispatch and Netty.
If you like my Akka answers on Stackoverflow then you'll love my book, Mastering Akka. Pick yourself up a copy on pre-sale today. Links below:
