Put the awesome redux-devtools in it's own window so it doesn't obscure or be obscured by your application
// give it a name so it reuses the same window
var win = window.open(null, "redux-devtools", "menubar=no,location=no,resizable=yes,scrollbars=no,status=no");
// reload in case it's reusing the same window with the old content
win.location.reload();
// wait a little bit for it to reload, then render

# A modification of https://gist.github.com/1064640/ to include a white-list of URLs

# Despite the W3C guidance suggesting that a list of origins can be passed as part of

# don't seem to play nicely with this.

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.

An EventMachine Syslog Protocol
# this is a configurable version of an EventMachine syslogger
# It was build to replace https://github.com/melito/em-syslog
#
# You can instantiate many of them (no global variables) as
# well as configure the facility. It also quacks like a ruby
# logger so it can be interchanged with a ruby logger.
#
# Example:
#
# # 11 is the facility code for an FTP daemon
