- The actor model is a conceptual model to deal with concurrent computation. It defines some general rules for how the system’s components should behave and interact with each other. The most famous language that uses this model is probably Erlang.

Actor model. The actor model in computer science is a mathematical model of concurrent computation that treats an actor as the basic building block of concurrent computation. In response to a message it receives, an actor can: make local decisions, create more actors, send more messages, and determine how to respond to the next message received.

The actor model is a conceptual model to deal with concurrent computation. It defines some general rules for how the system’s components should behave and interact with each other. The most famous language that uses this model isprobably Erlang. I’ll try to focus more on the model itself and not in how it’s implemented in different languages or lib...
An actor is the primitive unit of computation. It’s the thingthat receives a message and do some kind of computation based on it. The idea is very similar to what we have in object-oriented languages: An object receives a message (a method call) and does something dependingon which message it receives (which method we are calling). The main differe...
Erlang introduced the “let it crash” philosophy. The idea is that you shouldn’t need to program defensively, trying to anticipate all the possible problemsthat could happen and find a way to handle them, simply because there is no way to think about every single failure point. What Erlangdoes is simply letting it crash, but make this critical code ...
Another interesting aspect of the actor model is that it doesn’t matter if the actor that I’m sending a message to is running locally orin another node. Think about it, if an actor is just this unit of code with a mailbox and an internal state, and it just respond to messages, who cares in whichmachine it’s actually running? As long as we can make ...
This was a quick overview of the conceptual model that is the base of great languages like Erlang and Elixir and librarieslike Akka (for the JVM) and Celluloid (for Ruby). If I was successful in making you curious about how this model is implemented and used in the real world,this is the list of books that I read or am reading about this topic and ...
Mar 21, 2009 · The Actor Model can be thought as OOP with special treatment to messages: they are delivered asynchronously and executed synchronously by the receiver. Every actor is identified with a unique address by which you send messages to it.
May 30, 2023 · The actor model has been around for quite a while, dating back to the 1970’s. That it’s used with frameworks like Akka and built natively into languages like Erlang are testaments to its utility.
