Submission + - NVIDIA Reveals Details On Pascal GPU With Up To 16GB Of HBM2, 1TB/Sec Bandwidth (hothardware.com)

MojoKid writes: This week at NVIDIA's GPU Technology Conference in Japan, the company announced that their next gen GPU, code named Pascal, will have close to a 2x performance-per-watt improvement over the current Maxwell GPU architecture. It was also been revealed that Pascal will be produced using TSMC's 16nm FinFET process, which will put it right up against AMD which is moving to use 14nm/16nm with two new Graphics Core Next (GCN) products in 2016. Other improvements including replacing PLX PCIe Gen3 bridging with NVLink, which enables bi-directional communications between two GPUs at 80GB/sec, up from 16GB/sec in NVIDIA's current generation Maxwell GPUs. Pascal also includes High Bandwidth Memory 2 (HBM2), which will significantly increase available memory bandwidth compared to current generation offerings. Flagship consumer Pascal boards will ship with four 4GB modules, combining to provide up to 16GB of memory and up to 1TB/sec of bandwidth.

Submission + - Louis Friedman says humans will never venture beyond Mars (examiner.com)

MarkWhittington writes: Dr. Louis Friedman, one of the co-founders of the Planetary Society, is coming out with a new book, “Human Spaceflight: From Mars to the Stars,” an excerpt of which was published in Scientific America. Friedman revives and revises a version of the humans vs. robots controversy that has roiled through aerospace circles for decades. Unlike previous advocates of restricting space travel to robots, such as Robert Park and the late James Van Allen, Friedman admits that humans are going to Mars to settle. But there, human space travel will end. Only robots will ever venture further.

These stories get more and more attention of the media and every time they will emphasize that this is considered as a federal crime for which penalty is severe fines and possibly jail time. But this does not seem to be at all effective with the population.
The question is, are people doing this out of a really bad intention or are just not intelligent enough to understand the risks and the sentences they are facing for, literally, no personal gain?

Exactly. Spitzer is capable of detecting it as a very faint signal, knowing that the actual source is a star. If they are using EM communication, the prower is probably orders of magnitude smaller than the star emission itself. Good luck, catching that with sufficient SNR in the radio domain...

Submission + - Badly-Coded Ransomware Locks User Files And Throws Away Encryption Key

An anonymous reader writes: A new ransomware family was not tested by its developer and is encrypting user files and then throwing away the encryption key because of an error in its programming. The ransomware author wanted to cut down costs by using a static encryption key for all users, but the ransomware kept generating random keys which it did not store anywhere. The only way to recover files is if users had a previous backup. You can detect it by the ransom message which has the same ID:qDgx5Bs8H

Submission + - WaPo runs anti-Linux FUD article, claims Torvalds does not care about security (washingtonpost.com)

LichtSpektren writes: The Washington Post has put on its front page an article by Craig Timberg titled "The Internet’s future rests with a man who calls most security experts ‘completely crazy’". The purpose of this article fairly blatantly attempts to smear Linux as insecure and the kernel team as indifferent to matters of security.

Here are some examples. Under the heading "The Cassandras", the author attempts to paint kernel development as being a matter of the arbitrary preferences of Torvalds: "Because the Linux kernel is not produced by a business, it does not respond to market conditions in a conventional way, but it is unquestionably shaped by incentives — and, most of all, by Torvalds’s priorities". Is Timberg unaware that Google, Samsung, IBM, Red Hat, SUSE, and dozens of other security-minded companies submit plenty of security patches, and the funding to maintain them, for their own economic benefit?

Under the section "Signs of trouble", Timberg attempts to paint the 2011 "towelroot" exploit for the Android operating system as the fault of Linux, and then finishes off the section by writing: "The security stakes for the tech industry were underscored in the keynote address at an August summit on Linux security that pointedly compared the blinkered attitude of software makers today to that of the automobile industry in the 1960s, when cars functioned well but failed to protect people during unforeseen events such as crashes."

Should the Washington Post get away with this kind of FUD?

Submission + - MIT Drone Autonomously Avoids Obstacles at 30 MPH (roboticstrends.com)

An anonymous reader writes: Traditional obstacle-avoidance software uses images from each camera, and search through the depth-field at multiple distances to determine if an object is in the drone’s path. Such approaches are computationally intensive, meaning the drone can’t fly faster than 6 miles per hour without specialized processors.

Barry’s realization was that, at the fast speeds that his drone could travel, the world simply does not change much between frames. Because of that, he could get away with computing just a small subset of measurements — distances of 10 meters away.

“As you fly, you push that 10-meter horizon forward, and, as long as your first 10 meters are clear, you can build a full map of the world around you,” Barry says.

Take 2 polarized filters, and measure the amount of light that gets through as a function of the angle between them. With a classical model of polarization, you'd expect it to fall directly with the angle, but instead it falls of as cos^2 of the angle.

The classical E.M. theory perfectly predicts the cos^2 term. See Malus law.

What's really weird, though, is that of you take 2 polarizing filters at right angles, such that no light gets through, then stick a third between them at a 45 degree angle, then it's as bright as one filter alone.

No, you would have less power than a single polarizer. This also very well explained by Jones calculus.

No, with entanglement it would seem that you cannot force one particle to a state so that the other is switching as well. Thus, you cannot effectively use this as a communication channel.

A very crude picture can be stated as the following : you send two letters containing the same unique number (0...9) to both Alice and Bob (who also know this rule). When Alice opens her letter and reads the number, she knows that Bob has the same number but she cannot use that to communicate a particular number to Bob directly.
WARNING : This explanation is using the hidden variable model which is wrong, as the EPR paradox/Bell's inequality and these researchers are proving. But this is the only simple explanation I know (with my limited knowledge of QM) to convey the fact that entanglement can not be used as a communication channel.

This quantity of fuel is treated as a potential risk in France and in the EU mostly due to industrial catastrophes such as Seveso (Italy) in 76 or AZF in 01. The zoning laws are now pretty strict for sites having large stocks of flammable/explosive materials. It also appears that this data-center has several aerial container.

For the noise, my guess is that the court ruling is only temporary and will require the owner of the facility to shield the sources.

Submission + - Bank's severance deal requires IT workers to be on call for two years (computerworld.com) 3

dcblogs writes: SunTrust Banks in Atlanta is laying off about 100 IT workers as it moves work offshore. But this layoff is unusual for what it is asking of the soon-to-be displaced workers: The bank's severance agreement requires terminated employees to remain available for two years to provide help if needed, including in-person assistance, and to do so without compensation. Many of the affected IT employees, who are now training their replacements, have years of experience and provide the highest levels of technical support. The proof of their ability may be in the severance requirement, which gives the bank a way to tap their expertise long after their departure. The bank's severance includes a "continuing cooperation" clause for a period of two years, where the employee agrees to "make myself reasonably available" to SunTrust "regarding matters in which I have been involved in the course of my employment with SunTrust and/or about which I have knowledge as a result of my employment at SunTrust."

When a new species is discovered, the honor of naming it goes to whoever found it. However, Eric H. Metzler, an entomologist from the Wedge Entomological Foundation, decided to ask Western National Parks Association—who funded some of his research—to start an online auction and take the proceeds.
