Functional Programming Principles in Scala [1] taught by
Martin Odersky, professor at EPFL and creator of the Scala language.
I did the course on the first or second run however, not sure if it has been kept up to date or if it is still well run.
Was disappointed with the follow up courses though, the lecturers didn't live up to Odersky.
The first course was great. I agree that Odersky is a very good lecturer, organized and easy to follow. I'd recommend it to anyone interested in Scala.
The second course was OK but not quite as good, it felt a little less systematic. It was mostly Odersky, but for part of the final week the course switches tracks to a different lecturer who clearly was preparing slides for a different lecture series, and I thought both the lectures weren't as clear and the stitch-in of the different material wasn't handled smoothly.
I've just started the third and while it's not Odersky, the lecturers have been good so far.
