Qubes is a Linux Operating System based around the concept of Virtual Machines (like multiple computers you can switch between) making full use of compartmentalisation.
Compartmentalisation allows you to take control of your digital life and is what the 10 Steps to Escape the Digital Prison is also based around.
Qubes is the Operating System used and recommended by Edward Snowden (NSA whistle blower)and seems to be the ultimate privacy Operating System
This is why I am interested and about to start build my own Qubes system.
Most people are not ready to switch to an Operating System like Qubes, but for those interested this video will give you a glimpse at what using and managing the Qubes privacy operating system is like.
