It has R̶u̶b̶y̶’̶s a Ruby-inspired syntax and compiles to native code. It is actually unreal how similar to Ruby this language looks like.<br>This language combines efficient code with developer productivity, adds full OOP, a great
Introduction to Concurrency Models with Ruby. Part II
In the second part of our series we will take a look at more advanced concurrency models such as Actors, Communicating Sequential Processes, Software Transactional Memory and of course Guilds — a new concurrency model which may be implemented in Ruby 3. If you haven’t read our first post in the series, I’d definitely recommend reading it first. There I described Processes, Threads, GIL, EventMachi
RubyKaigi 2017, September 18..20, Hiroshima, Japan #rubykaigi
Masatoshi Seki is a Ruby committer and the author of several Ruby standard libraries including dRuby, ERB, and Rinda. He’s an expert in object-oriented programming, distributed systems, and eXtreme programming. He has been speaking at RubyKaigi every year since 2006 when the Kaigi first started. Ruby threads are amazing, but for some reason they don't seem to be very popular. So I decided I'd try
Concurrency Deep Dive: Event loops | AppSignal Blog
Welcome to the last Ruby Magic article in our series about concurrency. In the previous editions we implemented a chat server using multiple processes and multiple threads. This time we're going to do the same thing using an event loop. Recap We're going to use the same client and the same server setup we used in the earlier articles. Our aim is to build a chat system that looks like this: Please
Concurrency Deep Dive: Multi-process | AppSignal Blog
In a previous Ruby Magic article on Mastering Concurrency, we gave an introduction to the three methods of achieving concurrency that are available to us as Ruby developers. This article is the first in a three-part series where we take a deep dive into each method. First up: Multi-process. With this method a master process forks itself to multiple worker processes. The worker process does the act
Concurrency in Rails 5.0
My previous posts on concurrency in ActiveRecord have been some of the most popular on this blog (which I’d like to think means concurrency is getting more popular in Rails-land), so I’m going to share what I know about some new concurrency architecture in Rails5 — which is no longer limited to ActiveRecord. (update: Hours before I started writing this unawares, matthewd submitted a rails PR for a

Mastering Concurrency | AppSignal Blog
Mastering concurrency Multiple people will use your app at the same time, and you want to deliver your app as fast as possible. So you'll need some way to handle concurrency. Fear not! Most web servers already do this by default. But when you need to scale, you want to use concurrency in the most efficient way possible. Different types of concurrency There are multiple ways to handle concurrency:
Celluloidのはなし - Qiita
require 'celluloid' class Counter include Celluloid attr_reader :count def initialize @count = 0 end def increment(n = 1) sleep n @count += n end end actor = Counter.new p actor.count #=> 0 p actor.increment #=> 1 p actor.async.increment(41) #=> nil p actor.count #=> 1 Celluloidの機能を使うには、ActorにしたいクラスにCellloidをincludeします。 #asyncをはそれに続くメソッド呼び出しが非同期になるようなプロキシを返します。メソッド呼び出しはnilを返すため、本来返ってくるはずの返り値は使えません
