This video is for programmers of all levels (although I write Scala, naturally). We discuss how some computations are synchronous and blocking, async and blocking, and how we could achieve async non-blocking computations with Akka actors.
Async and non-blocking is what you want. However, even that has its drawbacks. So at the end I show how you can also obtain meaningful values out of a non-blocking computation.
