When using Homebrew (http://brew.sh) and searching formulas or pull requests you may get the dreaded error message: Github API Rate limit exceeded

Let's fix that! (yeah!)

CREATE TABLE empsalary (

Add union_hack.rb to your project, for example at lib folder and ensure you're loading it on your application.rb file:

    # You'll need to add something like that
    config.autoload_paths += %W(#{config.root}/lib)

Then extend your favourite model with the module and you'll be able to do unions with unique records, sorted by any fields and limited in number of records (see my_timeline_method):

    class Profile < ActiveRecord::Base
      extend UnionHack

Prereq:

apt-get install zsh
apt-get install git-core

Getting zsh to work in ubuntu is weird, since sh does not understand the source command. So, you do this to install zsh
