These shoes were made for stalking

A friend of mine just gave me a pair of those way-kewl Nike shoes that include sensors which broadcast your footsteps to your iPod. As Apple and Nike proudly proclaim, their shoes are a revolution in fitness — because they allow an iPod to track precise information about how far you run and how many calories you burn. “Your shoes talk,” as Apple boasts. “Your iPod nano listens.”

And apparently, so does your creepy ex. A group of computer scientists at the University of Washington wondered if they could build a simple device to secretly track somebody by the signal emitted from their shoes. So they set up a laptop, and whaddya know: It turns out that each shoe broadcasts a unique identifier, and it took the scientists only a few hours to write computer code that would sniff it out and track it. They wrote a report summarizing the stalkertastic possibilities raised by the shoes, as their press release reports:

A jealous boyfriend could track a woman’s movements, or compare them with the movements of a suspected rival. And although a receiver only picks up the signal when a person is within range, a stalker could hide receivers near a home, a gym and a restaurant, for example, to closely monitor his or her target’s movements.

Nice! Of course, this is only the tip of the iceberg. As more and more products are shipped with radio-frequency ID labels, it’ll be increasingly easy for people to track where you’re going based on the radio-ID being constantly squirted out by, oh, your cup of coffee.

Speaking of which, you know those new credit cards with “blink” superfast payment technology — where you just wave the card at the cash register and it deducts the money? That’s also RFID technology, and as Boing Boing reported a while ago, those are pretty easy to scan and swipe your information from too. Time to start carrying your credit cards in a radio-proof Altoids tin!

From an interview with ethnobotanist and anthropologist Wade Davis:

One of the cultures you celebrate in Light at the Edge of the World is the Inuit. What do you most admire about them?

Davis: The Inuit didn’t fear the cold; they took advantage of it. During the 1950s the Canadian government forced the Inuit into settlements. A family from Arctic Bay told me this fantastic story of their grandfather who refused to go. The family, fearful for his life, took away all of his tools and all of his implements, thinking that would force him into the settlement. But instead, he just slipped out of an igloo on a cold Arctic night, pulled down his caribou and sealskin trousers, and defecated into his hand. As the feces began to freeze, he shaped it into the form of an implement. And when the blade started to take shape, he put a spray of saliva along the leading edge to sharpen it. That’s when what they call the “shit knife” took form. He used it to butcher a dog. Skinned the dog with it. Improvised a sled with the dog’s rib cage, and then, using the skin, he harnessed up an adjacent living dog. He put the shit knife in his belt and disappeared into the night.

“Video from a camp north of Toronto in December 2005 shows a car spinning around in a nearby, snow-covered parking lot. Prosecutors characterized that as special driver training but the defense, and many outsiders, said it was nothing more than “cutting doughnuts,” a favorite winter pastime of young Canadian motorists.” - A key piece of evidence submitted in the trial of a gang of alleged young Canadian terrorists.
