Over the last few months I've googled
Numerous Weapon Systems (I have a fascination with WW1, WWII and Cold War history - stuff like Black Arrow etc).
Insurgencies during the British Empire
Electronics (want to get back into and saw a fun project to make on reddit the other day) - http://www.youtube.com/watch?v=movVFYWheGM
Linux stuff (settings, security, the usual stuff a developer/system administrator would look at).
Programming stuff (relating to security, encryption etc)
NSA related material (following the story closely).
Setting up a VPN (so I can access Netflix US because Netflix UK is basically crap).
The US constitution and some case law.
NSA Report: "User noir_lord has an interest in privacy, weapons, insurgencies and excellent technical skills, user noir_lord should be monitored"
Where in reality I'm a 34 year old web developer from the North of England who enjoys history, techy stuff and playing with my cats.
