  • 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
