Install Java JDK 6.0 update 31 on Ubuntu 12.04 LTS

Introduction
The first question is why are we installing an old JDK. The answer is that Oracle JDK 6.0 update 31 is the JDK recommended by Cloudera when installing CDH4 (Cloudera Distribution Hadoop v4).

This is an update to an older version of this post. Mainly I have changed the JDK from 1.6.0_26 to 1.6.0_31 as this is the recommended JDK for CDH4 .

Install Java
I have a 64 bit version of Ubuntu 12.04 LTS installed, so the instructions below only apply to this OS.

# When an RSpec test like this fails,
# 
#   @my_array.should == [@some_model, @some_model2]
# 
# RSpec will call inspect on each of the objects to "help" you figure out
# what went wrong. Well, inspect will usually dump a TON OF SHIT and make trying
# to figure out why `@my_array` is not made up of `@some_model` and `@some_model2`
# really really painful.
#
# This little module and technique helps get around that. It will redefine `inspect`
