What does your mobile carrier know about you? Just how much information do they collect? And what the hell does it look like? German Green politician Malte Spitz has a brilliant TED talk showing what happened when he fought Deutsche Telekom to see just what was being collected under a European law -- and won. His prize? Six months of his mobile life. Some 35,830 lines of code. And an eye-opening look at what carriers, governments and, yes, private companies could learn about you.

It's far too easy to cry that the sky is falling when it comes to online privacy. (See Exhibits A, B, C and D, to note but a few.) But that doesn't mean there's not cause for concern, or that developers don't take it seriously. (They most certainly do.) Spitz, along with ZEIT ONLINE, has given us an incredible granular look at some of that data, but we each still need to be vigilant with our online lives.
