Speaking Sessions

  • WebSocket I/O with Ruby EventMachine

    1:45 PM Saturday   Room: 4201
    <b>Overview</b> In this session, I will cover using Ruby EventMachine to create a real-time - event driven - web application. This session will cover setting up an EventMachine server, Registering endpoints (unique websocket connections), and handling live or autonomous communication. <br/> <b>Session will cover following ruby technologies</b> <br/> 1. RVM - using rvm gemsets with .rvmrc ( - triggering use of custom rvm gemsets from within github repo<br/> 2. Gemfile (for bundle install) (gem install bundler)<br/> 3. Ruby EventMachine (<br/> 4. em-websocket (gem), em-http-request (gem) usage, patterns<br/> 5. JSON object serialization<br/> 6. Concurrent Programming in Ruby<br/> 7. Autonomous Communication <br/> <b>Session Application</b> <br/> During the course of this session, we will build a real-time, multi-threaded communications platform that can connect to any socket based endpoint, including another user, or HTTP API, or custom endpoint, or protocol. <br/> - Utilize html5 websockets and Json messaging to build an event-driven communications platform <br/> - Drive socket based communication utilizing the Observer and Reactor patterns<br/> - Use blocks (&block) to deliver http responses - from any 3rd party rest API - from your eventmachine server, back down through a websocket to the user who generated the request, or on time-based cycles.<br/> - Learn how to use Modules (mix-ins)<br/> - Build configuration files with YAML<br/> - Accept Command-Line arguments using ARGV<br/> - Have fun with other Ruby geeks!<br/>
