Scala and Wicket. Writing web apps is a dream. And I'm worried I won't get to do it in 2014, because the world has moved over to javascript, whose type system is 10 years behind scala's.
I'm not so sure about this. Python and Ruby seem to be just as popular as Node (if not more) for new projects, and as far as older projects go, PHP is still king.
My experience with Berlin startup scene is that Node.js took its niche and its popularity is not growing so rapidly now. There are more projects in Ruby and Python. I see there are couple more Scala jobs appeared and even saw 1-2 in Go.
