In this episode of Elixir Wizards, Xiang Ji and Nathan Hessler join hosts Sundi Myint and Owen Bickford to compare actor model implementation in Elixir, Ruby, and Clojure.
In Elixir, the actor model is core to how the BEAM VM works, with lightweight processes communicating asynchronously via message passing. GenServers provide a common abstraction for building actors, handling messages, and maintaining internal state. In Ruby, the actor model is represented through Ractors, which currently map to OS threads.
They discuss what we can learn by comparing models, understanding tradeoffs between VMs, languages, and concurrency primitives, and how this knowledge can help us choose the best tools for a project.
Topics discussed in this episode:
Difference between actor model and shared memory concurrency
Isolation of actor state and communication via message passing
BEAM VM design for high concurrency via lightweight processes
GenServers as common abstraction for building stateful actors
GenServer callbacks for message handling and state updates
Agents as similar process abstraction to GenServers
Shared state utilities like ETS for inter-process communication
Global Interpreter Lock in older Ruby VMs
Ractors as initial actor implementation in Ruby mapping to threads
Planned improvements to Ruby concurrency in 3.3
Akka implementation of actor model on JVM using thread scheduling
Limitations of shared memory concurrency on JVM
Project Loom bringing lightweight processes to JVM
Building GenServer behavior in Ruby using metaprogramming
CSP model of communication using channels in Clojure
Differences between BEAM scheduler and thread-based VMs
Comparing Elixir to academic languages like Haskell

On today’s episode, Elixir Wizards Owen Bickford and Dan Ivovich compare notes on building web applications with Elixir and the Phoenix Framework versus Ruby on Rails. They discuss the history of both frameworks, key differences in architecture and approach, and deciding which programming language to use when starting a project.
Both Phoenix and Rails are robust frameworks that enable developers to build high-quality web apps—Phoenix leverages functional programming in Elixir and Erlang’s networking for real-time communication. Rails follows object-oriented principles and has a vast ecosystem of plug-ins. For data-heavy CRUD apps, Phoenix's immutable data pipelines provide some advantages.
Developers can build great web apps with either Phoenix or Rails. Phoenix may have a slight edge for new projects based on its functional approach, built-in real-time features like LiveView, and ability to scale efficiently. But, choosing the right tech stack depends heavily on the app's specific requirements and the team's existing skills.
Topics discussed in this episode:
History and evolution of Phoenix Framework and Ruby on Rails
Default project structure and code organization preferences in each framework
Comparing object-oriented vs functional programming paradigms
CRUD app development and interaction with databases
Live reloading capabilities in Phoenix LiveView vs Rails Turbolinks
Leveraging WebSockets for real-time UI updates
Testing frameworks like RSpec, Cucumber, Wallaby, and Capybara
Dependency management and size of standard libraries
Scalability and distribution across nodes
Readability and approachability of object-oriented code
Immutability and data pipelines in functional programming
Types, specs, and static analysis with Dialyzer
Monkey patching in Ruby vs extensible core language in Elixir
Factors to consider when choosing between frameworks
Experience training new developers on Phoenix and Rails
Community influences on coding styles
Real-world project examples and refactoring approaches
Deployment and dev ops differences
Popularity and adoption curves of both frameworks
Ongoing research into improving Phoenix and Rails

Today on Elixir Wizards, Manuel Rubio, author of Erlang/OTP: A Concurrent World and Dan Plyukhin, creator of the UIGC Actor Garbage Collector for Akka, join host Dan Ivovich to compare notes on garbage collection in actor models.
The discussion digs into the similarities and differences of actor-based garbage collection in Erlang and Akka and introduces Dan's research on how to perform garbage collection in a distributed actor system.
Topics discussed:
Akka is akin to Erlang actors for the JVM using Scala, with similar principles like supervision trees, messages, and clustering
Erlang uses generational garbage collection and periodically copies live data to the old heap for long-lived elements
Actor GC aims to determine when an actor's memory can be reclaimed automatically rather than manually killing actors
Distributed actor GC is more challenging than object GC due to the distributed nature and relationships between actors across nodes
Challenges include reasoning about failures like dropped messages and crashed nodes
GC balance requires optimization of resource release and CPU load management
Immutability helps Erlang GC, but copying data for messages impacts performance
Research into distributed actor GC is still ongoing, with opportunities for improvement
Fault tolerance in Erlang relies on user implementation rather than low-level guarantees
Asynchronous messages in Erlang/Elixir mean references may become invalid which is similar to the distributed GC approaches in Dan's research
Idempotent messaging is recommended to handle possible duplicates from failures
