Forgive me if this is a stupid question, but what makes actors so lightweight?
To be honest, I'm not even sure how they work. Aren't they separate threads?

I don't understand why authors said that Code Listing 9.1 from "Programming in Scala" use closure. In chapter 9, they show how to refactor code into more less duplicated form, from this original code:
object FileMatcher {
private def filesHere = (new java.io.File(".")).listFiles
def filesEnding(query:…

Hi,
We're looking at using actors in our Scala code quite soon. We're also thinking of moving to Scala 2.8 in the next few weeks. We've been keeping an eye on Akka but it doesn't currently support 2.8 and plans for it have slipped from the 0.7 release to 0.8
We would like distributed, supervised…

I am trying to parallelise a code using scala actors. That is my first real code with actors, but I have some experience with Java Mulithreading and MPI in C. However I am completely lost.
The workflow I want to realise is a circular pipeline and can be described as the following:
Each worker actor…
