How To Generate Quantum Random Numbers With A Smartphone Camera
Bruno Sanguinetti and pals at the University of Geneva in Switzerland have worked out how to generate random numbers on an ordinary smartphone using genuine quantum processes. And they say their new technique can produce random numbers at the rate of 1 megabit per second, more than enough for most security applications.

Could Soylent Replace Food?
Rhinehart removed the Soylent. In the formula that he and his teammates have settled on, the major food groups are all accounted for: the lipids come from canola oil; the carbohydrates from maltodextrin and oat flour; and the protein from rice. To that, they’ve added fish oil (for omega-3s; vegans can substitute flaxseed oil), and doses of various vitamins and minerals: magnesium, calcium, electrolytes. Rhinehart is reluctant to associate Soylent with any flavor, so for now it just contains a small amount of sucralose, to mask the taste of the vitamins. That seems to fit his belief that Soylent should be a utility. “I think the best technology is the one that disappears,” he said. “Water doesn’t have a lot of taste or flavor, and it’s the world’s most popular beverage.” He hoisted the pitcher of yellowish-beige liquid. “Everything your body needs,” he said. “Do you want to try some?”
