/* Merge multiple RSS feeds with SimplePie
 *
 * Just modify the path to SimplePie and 
 * modify the $feeds array with the feeds you want
 *
 * You should probably also change the channel title, link and description,
 * plus I added a CC license you may not want
 *
 * Help from: http://www.webmaster-source.com/2007/08/06/merging-rss-feeds-with-simplepie/

Running redis using upstart on Ubuntu

I've been trying to understand how to setup systems from the ground up on Ubuntu. I just installed redis onto the box and here's how I did it and some things to look out for.

To install:

if Rails.env.development?
  module My
    module PartialRenderer
      def render(context, options, block)
        msg = "rendering '#{options[:partial]}' with locals '#{(options[:locals] || {}).keys}'"
        "<!-- start #{msg}-->\n#{super(context, options, block)}\n<!-- end #{msg}-->\n".html_safe
      end
    end
  end
