Actor Model and Concurrent Processing in Elixir vs. Clojure and Ruby with Xiang Ji & Nathan Hessler 47:57

1 year ago47:57

47:57

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 Remote and theScore are hiring!

Web Development Frameworks: Elixir and Phoenix vs. Ruby on Rails with Owen Bickford & Dan Ivovich 41:41

1 year ago41:41

41:41

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 Links Mentioned in this Episode: SmartLogic.io Dan’s LinkedIn Owen’s LinkedIn Ruby https://www.ruby-lang.org/en/ Rails https://rubyonrails.org/ Sams Teach Yourself Ruby in 21 Days Learn Ruby in 7 Days Build Your Own Ruby on Rails Web Applications Django https://github.com/django Sidekiq https://github.com/sidekiq Kafka https://kafka.apache.org/ Phoenix Framework https://www.phoenixframework.org/ Phoenix LiveView https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html#content Flask https://flask.palletsprojects.com/en/3.0.x/ WebSockets API https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API WebSocket connection for Phoenix https://github.com/phoenixframework/websock Morph Dom https://github.com/patrick-steele-idem/morphdom Turbolinks https://github.com/turbolinks Ecto https://github.com/elixir-ecto Capybara Testing Framework https://teamcapybara.github.io/capybara/ Wallaby Testing Framework https://wallabyjs.com/ Cucumber Testing Framework https://cucumber.io/ RSpec https://rspec.info/…

Garbage Collection in Erlang vs JVM/Akka with Manuel Rubio & Dan Plyukhin 44:08

1 year ago44:08

44:08

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 Help your local researcher!
