"The tracking issues described in this document have all been relatively easy to exploit, and it only takes one person to package them up into a malicious app for others to use," the group wrote. "Most importantly though, these privacy issues are not inherent to the functionality of the app, and should have been caught during development and review." … [Read more...] about 6 million COVIDSafe downloads and a AU$60b JobKeeper data error

Sintering Whether or not they include urea, geopolymers are a promising alternative to sintering, the other main approach being explored for lunar construction, says Phil Metzger, a planetary scientist at the University of Central Florida and an expert on lunar resources. Sintering involves blasting regolith with high amounts of energy so that it melts together. Power is hard to come by on the Moon, and building large structures would require megawatt-scale solar farms that feed all their power to a sintering facility. It’s easier to scale polymer-based construction, but Metzger is skeptical that urine will end up being the superplasticizer of choice on the Moon. Instead, he says that polymers will likely be brought from Earth or mined from the lunar ice. … [Read more...] about On the Moon, astronaut pee will be a hot commodity
Hod offered that robotics is a pathway of that kind, the ability for machines to learn by navigating the world. LeCun concurred, referencing the work of Sergey Levine, a U.C. Berkeley professor whose lab does a lot of work on what might be called self-supervised, or semi-supervised learning in robotics systems. The same kind of work is going on at Facebook, LeCun noted. "One of the most interesting areas today is learning models of the world," he offered. "It would be a step toward the kind of learning humans do, which is different from supervised learning or reinforcement learning," he added. … [Read more...] about Artificial general intelligence is a Rorschach Test: Perhaps we need orangutans?
I have a soft spot for the film, standing as it does sort of on the bridge between Clarke’s slickly utopian machines-as-humans future and a grittier, '70s-influenced, hard-bitten dystopian corporate vision of the way things might be (though Hyams’ 1981 film Outland is far dirtier and grittier—and has far more exploding heads!). But like most films from the Cold War era, it failed to predict the end of Communism and the downfall of the Soviet Union. The central conflict in the film involves the Cold War turning very, very hot, and the lesson we’re supposed to take away—emphasized clumsily by a message from aliens—is that we need to all play nice because we’re all people. … [Read more...] about Video: Movies that predicted the future—and some that didn’t
