What we're about

We're a meetup focused on concurrent programming, concurrency models, distributed systems, and programming languages. We welcome both beginners and more seasoned coders.

The Wide World of Almost-Actors: Comparing Erlang, Elixir, and Pony

ABOUT THE SPEAKER: Scott Lystig Fritchie was a UNIX systems administrator until he returned to programming full-time at Sendmail, Inc. While at Sendmail in 2000, a colleague introduced him to Erlang. His world hasn't been the same since. In addition to writing Erlang and occasionally C for the Erlang virtual machine, he has had papers published by USENIX, the Erlang User Conference, and the ACM and has given presentations at Erlang Factory, Code BEAM, and Ricon. Scott works at Wallaroo Labs on a polyglot distributed system of Pony, Python, and C. TALK DESCRIPTION: Erlang and Elixir/OTP programmers take the Actor Model of computation for granted. Processes that communicate only by message passing makes building concurrent applications easy. The Pony language started with the same foundation as Erlang: message passing between independent, concurrent computing units. But the inventor of the Actor Model, Dr. Carl Hewitt, says that Erlang does not implement the Actor Model. Erlang co-creators Joe Armstrong and Robert Virding both agree with Hewitt. Why? Let's explore how Hewitt defines the Actor Model, how the BEAM VM implements parts of the Actor Model, and how the Pony language (which is statically-typed and VM-less) implements the Actor Model in similar & different ways. Talk objectives: - Have a solid understanding of what the Actor Model of computing is and the BEAM VM's interpretation of the model. - You will be very tempted to start writing safe, fast, concurrent programs in Pony. - You'll start seeing differences in other actor languages & frameworks used in industry, such as E, Scala, Akka, and Orleans.
