GNU/Linux UFW VPN kill switch tutorial

GNU/Linux UFW VPN kill switch tutorial

This is a quick guide for setting up a kill switch using UFW (Uncomplicated FireWall). It is assumed you are using OpenVPN and optionally Network-Manager with network-manager-openvpn.

A2DP audio streaming using Raspberry PI (Raspbian Jessie)

What is this all about?

This tutorial will turn your Raspberry PI into a simple Bluetooth audio receiver, which plays music through connected speakers. It's like a regular car audio system, but it can be used anywhere and it's a good value.
