# Description: Simple demo to showcase Redis PubSub with EventMachine | |
# | |
# Update 7 Oct 2010: | |
# - This example does *not* appear to work with Chrome >=6.0. Apparently, | |
# the WebSocket protocol implementation in the cramp gem does not work | |
# well with Chrome's (newer) WebSocket implementation. | |
# | |
# Requirements: | |
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby |
