Comment Variable-focus lenses have been done, but not auto (Score 1) 120

Variable-focus lenses have been tried before, but not autofocus. A friend had a manually controlled pair from Superfocus and loved them. But Superfocus is no longer selling them. http://www.allaboutvision.com/... The mechanisms used may differ, but the function is similar. What's new here is the autofocus feature - look at a scene, and a sensor will measure the distance and use that information to focus the lens as your visual system would do if your organic lens still had its depth adaptation capability. That's cool and potentially useful. They claim 5.8 diopter focusing range, good enough to go from distance to reading. But their prototype lens is 8.4 mm (1/3 inch) thick and weighs 14.4 gm. So there's a way to go yet.

Comment Looks like software, but more testing is needed (Score 1) 212

The inconsistency of Safari is weird and the difference from the consistent efficiency of Chrome is odd, but they stopped the tests too soon to tell us much. They should have run tests on Firefox and checked the Activity Monitor to see it they could spot obvious differences. One possibility is that interactions among Apple software may be contributing to the reduction of battery life.

Comment Correction - which "The New American": (Score 4, Informative) 437

Wrong group. The New American is indeed a magazine published by the John Birch Society, as clearly stated on their web site . However, the original poster made an error. Lina Khan is a fellow in a program run by The New America Foundation , which was founded in 1999. According to Soucewatch, the New America Foundation received over $6 million through 2013 from the Bill and Melinda Gates Foundation, and lesser amounts from other foundations. https://tech.slashdot.org/stor...

Comment Re:"Better" or just "Different"? (Score 2) 113

The more opaque Google gets, the harder it becomes to rely on their searches. User-specified options would help. Do you want a person, a place, a product? Do you want a fact search with a mobile display because you're discussing some arcane bit of history with a friend? As long as Google controls all the options, the search process remains opaque and becomes increasingly difficult to interpret.
