Hybrid concurrency patterns
Ruby developers need to stop using EventMachine. It's the wrong direction. Lost in the "Threads vs Event Driven vs Process Spawning" debate is that you can combine them! Learn how Celluloid is improving thread programming by abstracting them using a higher level framework called Celluloid, how you can use Celluloid::IO to throw a reactor pattern into a thread. Using this approach, you can take adv

If you really like evented programming, use node. Everything there is evented. I tried EventMachine and it just felt worse than node, documentation is worse, libraries are worse, it just wasn't a whole lot of fun.I haven't tried celluloid yet, but I've learned one lesson building things with PHP, Ruby, Python, Node, Java, Scala, etc. That lesson is to use tools with a community of people around it
Ruby 1.9 Fibers + EventMachine for Big Ruby Webapp Performance Gains
Ruby Weekly is a weekly newsletter covering the latest Ruby and Rails news. Developers hankering for more performance from their Rack and Rails applications are using Ruby 1.9 fibers and event-based EventMachine-driven libraries as a way to boost the performance of their applications - in opposition to scaling by merely running multiple processes or using threads. It's no secret that thread-based

EventMachine: Scalable Non-Blocking I/o in Ruby | PDF | Network Socket | Port (Computer Networking)
EventMachine is a Ruby library that implements non-blocking I/O using the reactor pattern similar to Python's Twisted. It allows Ruby applications to handle thousands of concurrent connections using a single process by avoiding blocking on I/O and using callbacks. EventMachine works across various Ruby implementations like MRI, YARV, Rubinius, and JRuby using different underlying reactors. It is c
Fast, concurrent ruby web applications with EventMachine and EM::Synchrony
Fast, concurrent ruby web applications with EventMachine and EM::Synchrony This document summarizes Kyle Drake's presentation on using EventMachine (EM) and EM::Synchrony to build fast, concurrent Ruby web applications without blocking I/O or callback hell. Key points include: - EM implements the reactor pattern to handle blocking I/O without threads by using callbacks and kernel threads. - EM::Sy
Any success with Sinatra working together with EventMachine WebSockets?
I have been using Sinatra for sometime now and I would like to add some realtime features to my web-app by pushing the data via websockets. I have successfully used the gem 'em-websocket' on its own, but have not been able to write one ruby file that has a sinatra web server AND a web-socket server. I've tried spinning the run! or start! methods off in separate threads with no success. Has anyone
Fiberを使ってem-http-requestとかを同期的に呼び出す - monthly gimite
EventMachineの関数(em-http-requestとか)を多用すると、コールバックだらけになって訳が分からなくなるのが欠点です。 Ruby 1.9のFiberを使うと、em-http-requestみたいな非同期関数を同期的に呼ぶことができます。em-synchronyというライブラリがそのようなラッパを提供してるのを見つけました。 require "em-synchrony" require "em-synchrony/em-http" p EM::HttpRequest.new("http://www.google.com").get.response p EM::HttpRequest.new("http://www.yahoo.com").get.response こうするとhttp://www.google.comとhttp://www.yahoo.comを順にロード
Fibers & Cooperative Scheduling in Ruby - igvita.com
By Ilya Grigorik on May 13, 2009 Continuations have been a part of the Ruby API for quite some time, but for a variety of reasons have not seen much practical use: early Ruby 1.8 implementations suffered from serious memory leak problems, which were consequently mostly resolved, and the somewhat academic nature of the concept didn't help either. However, with the production versions of Ruby 1.9 ou

What is EventMachine? EventMachine is a library for Ruby, C++, and Java programs. It provides event-driven I/O using the Reactor pattern. EventMachine is designed to simultaneously meet two key needs: Extremely high scalability, performance and stability for the most demanding production environments; An API that eliminates the complexities of high-performance threaded network programming, allowin
