A command that can be used on a Linux machine if you're running Gnome to delete the oldest image and movie thumbnails in your desktop's cache to reclaim disk space. I run this command once a month as a cronjob.

A website with a downloadable shell script which turns a raspi into a personal OpenVPN server. Lets you customize the configuration if you like. Appears to use a hardened OpenVPN configuration. The script will work with pretty much any Debian or Ubuntu v14.04 server you stand up someplace. The script can also be use to manage the server so you don't have to fight with the OpenVPN command lines.
