Jamie Ridgway explains what actors are, why we need them, what they are helpful for, the languages built around this programming paradigm, along with some demos showing actor-based apps.
Ulf Wiger advocates for a programming model change based on the actor model which more accurately reflects old human concurrency patterns that we have used in our daily lives for thousands of years.
Dale Schumacher explains the actor concept and how it helps us build a computational model resembling the reality around us more accurately than the object-oriented model.
Kresten Krab Thorup emphasizes existing problems with the Java concurrency model, explaining when to use Erjang, a JVM-based Erlang VM, built around the process and actor concepts.
Kresten Krab Thorup discusses functional and interactive concurrency, the message-based paradigm vs. OOP, a new way of doing programming based on concurrency, state encapsulation, and cheap processes.
This presentation discusses the functional programing paradigms used to build Buy a Feature, (a multi-user, web-based, real-time, serious game), including Actors, event streams, Scala and lift.
