Evented Ruby vs Node.js
While Node.js is the hot new kid on the block, evented libraries like EventMachine for Ruby and Twisted for Python have existed for a long time. When does it make sense to use one over the other? What are the advantages and disadvantages to using node over ruby?
This video explains how to get the same power of concurrency enjoyed by Node.js while continuing to write in the language you know and love. Topics covered include pubsub with redis or faye, building evented rack applications, and running evented applications alongside existing Rails apps.
