I've been going out of my way to not read permaculturebooks lately. I ran across this author and read a few of his books. Now I'm, seemingly properly, paranoid and stuff; Thanks Cory Doctorow.
His books can be found here: http://craphound.com/?cat=5 Little Brother, Homeland, and Lawful Interception all follow a young fellow by the name of Marcus Yallow. They are pretty fun and also deal with a lot of technology that is currently out in the world.
I wish kids would read this instead of Hunger Games...
They mention TOR (The onion router) as a way to anonymize your internet browsing. While it's not a perfect system (if your not using HTTPS people can still snoop on you.) it is kinda fun to play around with. I like to use it at my work to test our work websites. It's like an instant VPN to outside computers from inside my network.
On another topic, I was looking for an alternate to paying for dropbox (I really like dropbox, they are super secure and provide an awesome service.)
and I ran across BitTorrent Sync. This is basically dropbox but you provide the cloud.
I've set this up on a work computer, home computer, and a raspberry pi with an external USB Hard drive. It really seems to work well.
Basically, you need to have a couple computer for this to work properly, but The raspberry pi option could easily give you a 500GB-1TB "personal cloud storage" for around $100.
okay, I'm a little late to this topic but I love Cory Doctorow and highly recommend little brother as well as Down and Out in the Magic Kingdom. that book has some really excellent ideas about the future and it inspires me to this day.
