Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert

I recently had to install MySQL 5.6 on Ubuntu 12.04 from a .deb package on the MySQL website.  It seems that either the package has been updated recently or nobody uses this method to install so I ended up running into endless problems.  Through trial and error I found the following method works for me.

Install libaio-dev:
  sudo apt-get install libaio-dev

Now install your package(mine was enterprise edition, community may have a different filename):
  sudo dpkg -i mysql-advanced-5.6.10-debian6.0-x86_64.deb

This will install your files to the /opt directory, instead of the more common /etc directory.  No worries, all we need to do is point our system at this new directory.

//Sample HTML to use
<a class="modal-dialog"><img src="thumb.png" alt="Image Title" data-full-size="full-size.png"></a>


// Look for modal pop-ups
var modalPops = $("a.modal-dialog");

//If there's modals, inject all the necessary code.
if(modalPops.length) { 
  //First add the data attributes
