    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:

                Download a cacert.pem for RailsInstaller
              
          
    Why?

There is a long standing issue in Ruby where the net/http library by default does not check the validity of an SSL certificate during a TLS handshake. Rather than deal with the underlying problem (a missing certificate authority, a self-signed certificate, etc.) one tends to see bad hacks everywhere. This can lead to problems down the road.
From what I can see the OpenSSL library that Rails Installer delivers has no certificate authorities defined. So, let's go fetch some from the curl website. And since this is for ruby, why don't we download and install the file with a ruby script?
Installation

The Ruby Way! (Fun)

Beyond IP Transactions: towards a payment protocol
==================================================

IP transactions were originally introduced as a first "out-of-band" protocol
for negotiating a transaction output's public key. Being inconvenient and
insecure, they became obsolete, and recent versions of bitcoin don't support
them anymore.

The result is that static bitcoin addresses have become the most common way of
defining requested payments. This may be fine for anonymous donations, but is not
