Actor Model

There are several resources in the Internet explaining the Actor Model and Reactive Programing. Some videos with interesting interviews:

• Hewitt, Meijer and Szyperski: The Actor Model (everything you wanted to know, but were afraid to ask)[1]; and
• Francesco Cesarini and Viktor Klang on the Reactive Manifesto[2].

According to the WikiPedia[5] "the actor model in computer science is a mathematical model of concurrent computation that treats "actors" as the universal primitives of concurrent digital computation: in response to a message that it receives, an actor can make local decisions, create more actors, send more messages, and determine how to respond to the next message received."
