Most wine pH’s fall around 3 or 4; about 3.0 to 3.4 is desirable for white wines, while about 3.3 to 3.6 is best for reds.

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.”

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.
