Dark Matter Is Even More of a Mystery Than Expected 94

Posted by Soulskill
from the does-not-play-well-with-other-matter dept.
schwit1 writes: Using the Hubble and Chandra space telescopes astronomers have discovered that dark matter is not only invisible to direct observation, it is invisible to itself! Quoting: "As two galactic clusters collide, the stars, gas and dark matter interact in different ways. The clouds of gas suffer drag, slow down and often stop, whereas the stars zip past one another, unless they collide — which is rare. On studying what happens to dark matter during these collisions, the researchers realized that, like stars, the colliding clouds of dark matter have little effect on one another. Thought to be spread evenly throughout each cluster, it seems logical to assume that the clouds of dark matter would have a strong interaction — much like the colliding clouds of gas as the colliding dark matter particles should come into very close proximity. But rather than creating drag, the dark matter clouds slide through one another seamlessly." The data here is on the very edge of reality, built on too many assumptions. We know that something undetected as yet is influencing the motions of galaxies, but what exactly it is remains completely unknown. These results only make the mystery more mysterious.

Toshiba Announces 3D Flash With 48 Layers 21

from the going-to-need-an-elevator dept.
Lucas123 writes: Admitting it has bumped up against a 15 nanometer process wall, Toshiba announced it's focusing its efforts on three dimensional NAND using its Bit Cost Scalable technology (PDF) in order to increase capacity. It has dedicated a Japanese fab plant to it and developed 48-level 3D NAND, which bumps density up 33% over previous 3D NAND flash. The new 3D NAND will be able to store 128Gb of data per chip (16GB). Samsung has been mass producing 32-layer, triple-level cell (TLC) 3D NAND since last October and has incorporated it into some of its least expensive SSDs. Yesterday, Micron and Intel announced their own 32-layer 3D TLC NAND, which they claimed will lead to 10TB SSDs. While Toshiba's 3D NAND is multi-level cell (meaning it stores two bits per transistor versus three), the company does plan on developing a TLC version. Toshiba said it's not abandoning 15nm floating gate flash, but it will focus those efforts on lower capacity applications.

Hoax-Detecting Software Spots Fake Papers 32

Posted by Soulskill
from the solving-the-problems-we-created-for-ourselves dept.
sciencehabit writes: In 2005, three computer science Ph.D. students at the Massachusetts Institute of Technology created a program to generate nonsensical computer science research papers. The goal was "to expose the lack of peer review at low-quality conferences that essentially scam researchers with publication and conference fees." The program — dubbed SCIgen — soon found users across the globe, and before long its automatically generated creations were being accepted by scientific conferences and published in purportedly peer-reviewed journals. But SCIgen may have finally met its match. Academic publisher Springer this week is releasing SciDetect, an open-source program to automatically detect automatically generated papers. SCIgen uses a "context-free grammar" to create word salad that looks like reasonable text from a distance but is easily spotted as nonsense by a human reader.

mpicpp sends this report from CNET: The floodgates are now open for UK users to sue Google over privacy violations tied to tracking cookies. In a landmark ruling, the UK's Court of Appeal has dismissed Google's request to prevent British Web users from suing the company over tracking cookies and privacy violations. The decision was announced Friday, according to the BBC. In spite of default privacy settings and user preferences — including an opt-out of consent to be tracked by cookies — Google's tracking cookies gathered information on Safari browser users for nine months in 2011 and 2012.

Amazon Requires Non-Compete Agreements.. For Warehouse Workers 263

Posted by Soulskill
from the you-may-not-lift-and-carry-objects-for-anyone-else dept.
Rick Zeman writes: Amazon, perhaps historically only second to Newegg in the IT nerdling's online shopping heart, has not only subjected their warehouse employees to appalling working conditions, but they're also making them sign a non-compete agreement for the privilege. Here's an excerpt from the agreement: "During employment and for 18 months after the Separation Date, Employee will not, directly or indirectly, whether on Employee's own behalf or on behalf of any other entity (for example, as an employee, agent, partner, or consultant), engage in or support the development, manufacture, marketing, or sale of any product or service that competes or is intended to compete with any product or service sold, offered, or otherwise provided by Amazon (or intended to be sold, offered, or otherwise provided by Amazon in the future)."

Behind the Scenes At a Quantum Dot Factory 30

Posted by Soulskill
from the harvesting-the-dot-crop dept.
Tekla Perry writes: In a nondescript office complex in Milpitas, Calif., Nanosys is making enough quantum dots to populate 6 million 60-inch television screens annually. "The process goes on in what looks like a microbrewery. In about half a dozen large metal tanks ... Nanosys combines cadmium and selenium and adjusts the temperature, concentration, and catalysts added to force these precursors to combine into stable crystals of cadmium selenide. Then, by readjusting the conditions, the system stops the formation of crystals and triggers the beginning of crystal growth. A computer controls the process according to a programmed “recipe;” staff members monitor the growth of the crystals by shining light on them and measuring the wavelength of the fluorescence; the smallest crystals don’t fluoresce at all, then, as the crystals get larger, the wavelength changes. Nanosys stops the process when the fluoresced light hits the target wavelength, which varies depending on what particular display industry standard that the batch of film is designed to meet."

In a landmark ruling, the UK's Court of Appeal has dismissed Google's request to prevent British Web users from suing the company over tracking cookies and privacy violations.

The decision was announced Friday, according to the BBC.

The case revolves around Apple's Safari browser, Google's Safari workaround, and cookies — small text files installed on PCs that record data on surfing activity. In spite of default privacy settings and user preferences — including an opt-out of consent to be tracked by cookies — Google's tracking cookies gathered information on Safari browser users for nine months in 2011 and 2012.

Google profits from DoubleClick tracking cookies by installing them on computing devices and leading users to tailored advertisements. The DoubleClick ID Cookie, when settled within a user's browser, tracks and gathers data about the user based on Web activity and searches.

This information can include surfing habits, ethnicity, sexual interests, religious and political beliefs, and potentially financial data."

braindrainbahrain writes: Hacker Oscarv wanted a PDP-8 mini computer. But buying a real PDP-8 was horribly expensive and out of the question. So Oscarv did the next best thing: he used a Raspberry Pi as the computing engine and interfaced it to a replica PDP-8 front panel, complete with boatloads of fully functional switches and LEDs.

Modern Cockpits: Harder To Invade But Easier To Lock Up 323

Posted by Soulskill
from the difficulty-with-edge-cases dept.
HughPickens.com writes: Jad Mouawad And Christopher Drew write in the NY Times that although airplane cockpits are supposed to be the last line of defense from outside aggressors, airlines have fewer options if the threat comes from within. One of the major safety protocols that actually made planes safer in the past 15 years was that the cockpits were turned into fortresses. Unfortunately, that exact advantage was exploited by the co-pilot of the Germanwings plane on Tuesday to crash it intentionally. "It is shocking to me that there was not a second person present in the cockpit," says Mark Rosenker, a former chairman of the National Transportation Safety Board. Access to the cockpit is strictly regulated in the United States. Passengers are not allowed to congregate near the cockpit door, and whenever the door is open, no one is allowed in the forward bathroom and flight attendants usually block aisle access, sometimes using a food cart. The Federal Aviation Administration mandates that a flight attendant must sit in the cockpit when either pilot steps into the passenger area; European regulations do not have a similar two-person rule, but they're now talking about creating one.

The Germanwings accident also points to potential shortcomings in how pilots are screened for mental problems, a recurring concern for an industry that demands focus and discipline in an increasingly technical job, often in stressful situations. In 2012, a well-regarded pilot with JetBlue, one of the airline's earliest employees, was physically restrained by passengers on a flight from New York to Las Vegas after displaying erratic behavior. In that case, the co-pilot locked the pilot out of the cabin and made an emergency landing in Amarillo, Tex. "Aircraft-assisted pilot suicides," as the Federal Aviation Administration calls them, are rare. They include the November 2013 crash of a Mozambique Airlines plane bound for Luanda, Angola, which bears an eerie resemblance to the Germanwings plane's demise. When the flight's co-pilot left to use the lavatory, the captain locked him out of the cockpit and manually steered the aircraft earthward. The crash of Egypt Airlines Flight 990 off Nantucket, Mass., in 1999, which killed all 217 people on board, was also caused by deliberate action, a National Transportation Safety Board investigation concluded. Experts on suicide say that the psychology of those who combine suicide with mass murder may differ in significant ways from those who limit themselves to taking their own lives.

US Air Force Overstepped In SpaceX Certification 57

Posted by Soulskill
from the don't-ruin-this-for-us,-government dept.
Rambo Tribble writes: An internal review commissioned by Air Force Secretary Deborah James has concluded that Air Force personnel tasked with evaluating SpaceX's certification treated it as a design review, going so far as to dictate organizational changes in the company. This was judged contrary to the intention of promoting a competitive environment. The report, prepared by former Air Force Chief of Staff General Larry Welch, concluded, "The result to date has been ... the worst of all worlds, pressing the Falcon 9 commercially oriented approach into a comfortable government mold that eliminates or significantly reduces the expected benefits to the government of the commercial approach. Both teams need to adjust."

jones_supa (887896) writes "Intel Linux developers have landed a lot of Broadwell CPU architecture enablement code into Coreboot. While there has been basic Broadwell support code within Coreboot for a number of months, pushed in the past few hours has been a lot more Broadwell code. This is likely an indication that more Google Chromebooks based on this latest-generation Intel architecture should be surfacing soon. See the patches in Coreboot Git browser."

Github Under JS-Based "Greatfire" DDoS Attack, Allegedly From Chinese Government 107

Posted by Soulskill
from the year-of-the-ddos dept.
An anonymous reader writes: During the past two days, popular code hosting site GitHub has been under a DDoS attack, which has led to intermittent service interruptions. As blogger Anthr@X reports from traceroute lists, the attack originated from MITM-modified JavaScript files for the Chinese company Baidu's user tracking code, changing the unencrypted content as it passed through the great firewall of China to request the URLs github.com/greatfire/ and github.com/cn-nytimes/. The Chinese government's dislike of widespread VPN usage may have caused it to arrange the attack, where only people accessing Baidu's services from outside the firewall would contribute to the DDoS. This wouldn't have been the first time China arranged this kind of "protest."

Quebec Plans To Require Website Blocking, Studies New Internet Access Tax 227

Posted by Soulskill
from the welcome-to-the-information-supertollroad,-eh dept.
An anonymous reader writes: Michael Geist reports that the Government of Quebec released its budget (PDF) yesterday featuring two Internet-related measures that are sure to attract attention and possible litigation. First, it is moving forward with plans to study a new tax on residential Internet services in order to provide support for the cultural sector. Second, the government says it will be introducing a new law requiring ISPs to block access to online gambling sites. The list of blocked sites will be developed by Loto-Quebec, a government agency. The government views this as a revenue enhancing measure because it wants to channel gamblers to its own Espacejeux, the government's own online gaming site.
