Carl Hewitt on Actors

Actor - Fundamental unit of computation, a computation model - not just a form of concurrency

An Actor has three essential elements:

• 1 - Processing - you have to get something done
• 2 - Storage - you have to be able to remember things
• 3 - Communication

From Out of the Tar Pit:

The key problem with testing is that a test (of any kind) that uses one particular set of inputs tells you nothing at all about the behaviour of the system or component when it is given a different set of inputs. The huge number of different possible inputs usually rules out the possibility of testing them all, hence the unavoidable concern with testing will always be — have you performed the right tests?. The only certain answer you will ever get to this question is an answer in the negative — when the system breaks.

This is a strong argument for some form of generative, simulation, or property-based testing.
