First time I opened this website I watched a girl sunbathing near a lake. She had no idea anyone could watch her security camera. Like her, many people let their cameras connected to the internet without a password. Insecam exposes this problem allowing you to watch those cameras. All legal and creepy.
One time I heard about the "Way of Samurai", in basic words it's about doing your own things, avoid the black box of just buying things without know how works. Instructables teaches you doing almost everything by yourself. It's amazing the knowledge of handmade this site has.
