I have a backlog of courses on Coursera. Right now it's this one, the NLP course and Andrew Ng's ML course. I have a project in mind that would benefit greatly from all three.

I've started putting it together in small pieces but ML and NLP are tough topics to learn without some sort of instruction.

I have a pretty good grasp of Scala but I learned in sort of an ad-hoc fashion and I'm looking forward to learning what I imagine will be idiomatic Scala.

Andrew Ng's course ideally excellent, he's a very good lecturer.

I'm liking this course too, it's really about functional programming more than Scala. He says in the first lecture that the curriculum is mostly from a well known book on scheme, just with the languages swapped out.

The NLP course needs some improvement in particular the Chris Manning sections. It was allow over the internal discussion forums. Dan Jurafsky was very good, can't say the same about Chris Manning.
