# 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

def tree(): return defaultdict(tree)

That's it!

Setting up github and bitbucket on the same computer (Windows)

Guide for Windows

mix3d asked for some help using this guide with windows so here we go. This was tested with Windows 10. Run all commands in Git Bash once it's installed.

Git for Windows

• Download and install Git for Windows
  • In the installer, select everything but decide if you want a desktop icon (2nd step)
