Recently I wanted to optimise the performance of MongoDB for test and development environments where persistent data storage and logging isn't important. I also wanted a solution that was easy to deploy and maintain across multiple development machines.
Encrypting an Ubuntu Server that you have physical access is a fairly easy and straight forward process. But what happens if you don't have physical access to the server? How do you enter the passphrase to unlock the drive during boot?
I've been considering moving my data off of cloud services such as CrashPlan and Dropbox and putting it back onto hardware that I own and fully control. In my new setup I have opted to store my data in a fault tolerant method using ZFS.

I have an ACR122U NFC smartcard reader that I use with Linux Mint 17.1 and Kubuntu 15.04. This is a quick guide on how to get the reader working from a clean install of Mint or Kubuntu.
