Above the Clouds: Introducing Akka
Jonas Bonér introduces Akka, a JVM platform that wants to address the complex problems of concurrency, scalability and fault tolerance using Actors, STM and self-healing from crashes.

Actor-based Programming
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.

1000 Year-old Design Patterns
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.

Perception and Action: An Introduction to Clojure's Time Model
Stuart Halloway discusses how we use a total control time model, proposing a different one that represents the world more accurately helping to solve some of the concurrency and parallelism problems.

Actor Thinking
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.

Erjang - A JVM-based Erlang VM
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.

Modeling Concurrency with Actors in Java - Lessons Learned from Erjang
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.

Test-Driven Development of Asynchronous Systems
Nat Pryce exemplifies how he dealt with flickering, false positives, slow, and messy tests appearing in asynchronous testing when trying to perform end-to-end testing.

Death by Accidental Complexity
Ulf Wiger shows how concurrency can lead to accidental complexity if it is badly implemented in code, becoming a project’s point of failure. Wiger also advises on how concurrency should be addressed.
