YunoHost

Version of Linux which makes it as easy as possible to install and maintain your own self-hosted online services. There’s a really easy graphical interface, it works on home servers or remote ones, and it supports older and lower powered computers too.

Tails

A special version of Linux that aims for maximum privacy and anonymity. Tails runs entirely off a USB stick, it uses the Tor network to connect to the internet, and by default it resets/forgets everything you’ve done when you switch it off. (You can also optionally save encrypted data if you need to keep something.)
