Bitcoin Mining On Raspberry Pi

This is a quick and dirty guide to Bitcoin Mining on your Raspberry Pi. It's not going to be fast or efficient and may cause damage. I'm not responsible if you break anything, kill a cat or your wife leaves you as a result of this.

The following commands are to be run via either Terminal on the Pi or via SSH. If you are looking for a Windows SSH client, I recommend PuTTY

#/etc/init.d/vboxdrv setup Not Found - VirtualBox Fix!

When setting up Virtual Box I was faced with the immortal error telling me to run sudo /etc/init.d/vboxdrv setup. Simple enough, until you're told it doesn't exist.

Thus began my fight to get it working. The fix is here in the hope that it helps someone else.

To follow this guide you need to have a basic understanding of shell commands. If you don't, then just be careful.

First off I like aptitute so let's install it.
