Colleges are turning students’ phones into surveillance machines – The Washington Post

January 24, 2020

A rather worrisome article, with a great quote: “Building technology was a lot more fun before it went all 1984.”

But the perils of increasingly intimate supervision — and the subtle way it can mold how people act — have also led some to worry whether anyone will truly know when all this surveillance has gone too far. “Graduates will be well prepared … to embrace 24/7 government tracking and social credit systems,” one commenter on the Slashdot message board said. “Building technology was a lot more fun before it went all 1984.”

Fooling Big Brother – As face-recognition technology spreads, so do ideas for subverting it | Science and technology | The Economist

January 23, 2020


In 2010, for instance, as part of a thesis for a master’s degree at New York University, an American researcher and artist named Adam Harvey created “cv [computer vision] Dazzle”, a style of make-up designed to fool face recognisers. It uses bright colours, high contrast, graded shading and asymmetric stylings to confound an algorithm’s assumptions about what a face looks like. To a human being, the result is still clearly a face. But a computer—or, at least, the specic algorithm Mr Harvey was aiming at—is ba ed. …
An even subtler idea was proposed by researchers at the Chinese University of Hong Kong, Indiana University Bloomington, and Alibaba, a big Chinese information-technology rm, in a paper published in 2018. It is a baseball cap tted with tiny light-emitting diodes that project infra-red dots onto the wearer’s face. Many of the cameras used in face-recognition systems are sensitive to parts of the infra-red spectrum. Since human eyes are not, infra-red light is ideal for covert trickery.

The Day the Dinosaurs Died

January 5, 2020

“When I left Hell Creek, DePalma pressed me on the need for secrecy: I was to tell no one, not even close friends, about what he’d found. The history of paleontology is full of tales of bribery, backstabbing, and double-­dealing. In the nineteenth century, ­Othniel C. Marsh and Edward Drinker Cope, the nation’s two leading paleontologists, engaged in a bitter competition to collect dinosaur fossils in the American West. They raided each other’s quarries, bribed each other’s crews, and vilified each other in print and at scientific meetings. In 1890, the New York Herald began a series of sensational articles about the controversy with the headline “Scientists Wage Bitter Warfare.” The rivalry has since become known as the Bone Wars. The days of skulduggery in paleontology have not passed; DePalma was deeply concerned that the site would be expropriated by a major museum.” “}}
