I have recently started to develop a free course about Scala. The course will be available for free (for academic and personal usage) at www.abelski.com.
The slides of the first four topics have just been completed. You can download them at:

In addition, I have just taken two video clips to guide you with in your first steps.

Developing Hello World
Scala seems very promissing. Scala combines the best of Java and C#. I will be very glad to know your thoughts as well as getting feedback about the training material I have already developed. More info about the Scala programming language can be found at www.scala-lang.org.
