Slashdot videos: Now with more Slashdot!
We've improved Slashdot's video section; now you can view our video interviews, product close-ups and site visits with all the usual Slashdot options to comment, share, etc. No more walled garden! It's a work in progress -- we hope you'll check it out (Learn more about the recent updates).
We need strong encryption for use by law-abiding citizens, and weak encryption for use by criminals.
TSX was disabled in Broadwell and early Haswell chips due to a bug. Do these new Broadwell-U have the TSX fix?
I have an experimental workload for which TSX would be very helpful, due to a need for atomic reads and writes of unaligned 10-byte data items. As far as I can determine, x86 provides no other way to guarantee atomicity of an unaligned 10-byte read or write.
Wrong. We've produced "...machines that exhibit the agency and awareness of..." a worm: http://www.smithsonianmag.com/...
One vision of the future is already playing out in Grenoble, France, where residents can rent from a fleet of 70 pod-like Toyota i-Road and Coms electric cars for short city trips. "It is a sharing program like what you see in Portland with bicycles," says Lentz. Drivers can check out and return the cars at various charging points. Through a subscription, they pay the equivalent of $3.75 for 30 minutes. Because the vehicles are so small, its easy to build out their parking and charging infrastructure. Skeptics should consider the cynicism that greeted the horseless carriage more than a century ago, says Adam Jonas. He adds that fully autonomous vehicles will be here far sooner than the market thinks (PDF). Then, Jonas says, skeptics asked: "Why would any rational person want to replace the assuredness of that hot horse body trustily pulling your comfortable carriage with an unreliable, oil-spurting heap of gears, belts and chains?"
At the heart of their thinking is Heisenberg's uncertainty principle. This allows a small empty space to come into existence probabilistically due to fluctuations in what physicists call the metastable false vacuum. When this happens, there are two possibilities. If this bubble of space does not expand rapidly, it disappears again almost instantly. But if the bubble can expand to a large enough size, then a universe is created in a way that is irreversible. The question is: does the Wheeler-DeWitt equation allow this? "We prove that once a small true vacuum bubble is created, it has the chance to expand exponentially," say the researchers.
The case specifically involves cell tower data for a convicted drug dealer that police obtained from a telecom without a warrant. But the way the ruling is written (.pdf), it would also cover the use of so-called "stingrays" — sophisticated technology law enforcement agencies use to locate and track people in the field without assistance from telecoms. Agencies around the country, including in Florida, have been using the technology to track suspects — sometimes without obtaining a court order, other times deliberately deceiving judges and defendants about their use of the devices to track suspects, telling judges the information came from "confidential" sources rather than disclose their use of stingrays. The new ruling would require them to obtain a warrant or stop using the devices. The American Civil Liberties Union calls the Florida ruling "a resounding defense" of the public's right to privacy.
"The relationship between consumers and developers is symbiotic, one cannot exist without the other. If the Mac App Store is a hostile environment for developers, we are going to end up in a situation where, either software will not be supported anymore or even worse, won't be made at all. And the result is the same the other way around – if there are no consumers, businesses would go bankrupt and no software will be made. The Mac App Store can be work in ways that's beneficial to both developers and consumers alike, it doesn't have to be one or the other. If the MAS is harmful to either developers or consumers, in the long term, it will be inevitably harmful to both."
Perhaps. IEEE Spectrum credits Maruska, as do several other histories of the subject.
Maruska seems to have made the first working violet LED. Some people claim that it doesn't qualify as a blue LED, but as far as I know there's no agreed-upon hard distinction between violet and blue. Maruska developed the right materials and process to make it, even if RCA pulled the plug before he had solved all of the problems necessary for commercialization.
