MojoKid writes: Intel lifted the embargo veil today on performance results for its new Core i9-9900K 9th Gen 8-core processor. Intel claims the chip is "the best CPU for gaming" due to its high clock speeds and monolithic 8-core/16-thread design that has beefier cache memory (now 16MB). The chip also has 16-lanes of on-chip PCIe connectivity, official support for dual-channel memory up to DDR4-2666, and a 95 watt TDP. Intel also introduced two other 9th Gen chips today. Intel's Core i7-9700K is also an 8-core processor, but lacks HyperThreading, is clocked slightly lower, and has 4MB of smart cache disabled (12MB total). The Core i5-9600K takes things down to 6 cores / 6 threads, with a higher base clock, but lower boost clock and only 9MB of smart cache. In benchmark testing, the high-end Core i9-9900K's combination of Intel's latest microarchitecture and boost frequencies of up to 5GHz resulted in the best single-threaded performance seen from a desktop processor to date. The chip's 8-cores and 16-threads, larger cache, and higher clocks also resulted in some excellent multi-threaded scores that came close to catching some of Intel's many-core Core X HEDT processors in a few tests. The Core i9-9900K is a very fast processor, but it is also priced as such at $488 in 1KU quantities. That makes it about $185 to $225 pricier than AMD's Ryzen 7 2700X, which is currently selling for about $304 and performs within 3% to 12% of Intel's 8-core chip, depending on workload type.

An anonymous reader quotes a report from TechCrunch: Thermostats know the temperature of your house, and smart cameras and sensors know when someone's walking around your home. Smart assistants know what you're asking for, and smart doorbells know who's coming and going. And thanks to the cloud, that data is available to you from anywhere -- you can check in on your pets from your phone or make sure your robot vacuum cleaned the house. Because the data is stored or accessible by the smart home tech makers, law enforcement and government agencies have increasingly sought out data from the companies to solve crimes. And device makers won't say if your smart home gadgets have been used to spy on you. We asked some of the most well-known smart home makers on the market if they plan on releasing a transparency report, or disclose the number of demands they receive for data from their smart home devices. For the most part, we received fairly dismal responses. Amazon did not respond to requests for comment, but a spokesperson for the company said last year that it would not reveal the figures for its Echo smart speakers. Facebook said that its transparency report section will include "any requests related to Portal," its new hardware screen with a camera and a microphone. A spokesperson for the company did not comment on if the company will break out the hardware figures separately. Google also declined to comment, but did point TechCruch to Nest's transparency report. Apple, the last of the big tech giants, said that there's no need to disclose its smart home figures because there would be nothing to report, adding that user requests made to HomePod are given a random identifier that cannot be tied to a person. TechCrunch also asked a number of smaller smart home players, like August, iRobot, Arlo, Ring, Honeywell, Canary, Samsung, and Ecobee.

Some users on Reddit and Google's support forums are reporting an issue in which taking a photo using Google Camera occasionally fails to save. The issue appears to be widespread, "affecting original Pixel phones as well as the Pixel 2 / 2 XL," reports The Verge. From the report: The issue occurs specifically in cases when the user takes a photo with Google Camera, and switches to another app or locks the phone immediately after. Users are able to see a thumbnail of the photo in the Camera gallery circle, but upon tapping it, the photo disappears. In some occasions, the photo doesn't appear at all at first, but it will reappear in their gallery a day later.
There's also some reports of Galaxy S9, Moto Z2, Moto E4, and Nexus 5X owners experiencing the issue after using Google Camera, so it's unclear whether the issue is limited to Pixel phones or if it's connected to a larger Android bug. For now, users have come up with a workaround for an issue they believe is related to HDR photo processing time. Reddit user erbat suggests leaving the camera app open until HDR processing completes or turning off the HDR function completely.

Liquavista, a screen tech company Amazon acquired five years ago, has shut down. Rumblings of Liquavista's potential closure have been bouncing around the e-reader community for more than six months. It remains unclear if Liquavista's work has been brought inside Amazon and moved to other parts of the organization, or if it was shut down entirely. Amazon declined to release further details. From a report: Launched in 2006 as a spin off from Philips, Liquavista had been developing a unique type of screen tech that was based on running an electric current through a liquid. This is called electrowetting technology, which is a fancy way of saying that each pixel in a Liquavista screen contained 3 liquids (red, green, blue), and that the color shown by a pixel depended on the amount of power fed into each liquid. [...] The screens were originally being developed as a solution to the battery life issue. Mobile battery life was terrible back in the pre-iPad, pre-iPhone, and pre-netbook era, and people were willing to pay a premium for a screen which used less power than typical LCD screens.

An anonymous reader quotes a report from Ars Technica: Elon Musk took to Twitter on Thursday evening to inform his followers of a new addition to the Model 3 lineup. This is not the long-awaited $35,000 version, however; the mid-range Model 3 starts at $45,000. Musk also revealed that the Model 3 ordering process has been simplified and now has fewer options. One that's missing -- from all new Tesla orders, not just the Model 3 -- is the controversial "full self-driving" option. The reason? It was "causing too much confusion," Musk tweeted. The mid-range Model 3s will be rear-wheel drive only, prompting some to wonder if the company was using software to limit battery capacity on existing RWD inventory in order to get it out of the door. But Tesla says it's able to build these slightly cheaper cars by using the same battery pack as the more expensive, longer-range cars but with fewer cells inside (so no future software upgrades can increase their range at a later date). While Tesla is promoting the car as costing as little as $30,700 by factoring in "gas savings" and all federal and local tax incentives, it did also announce last week that any new Tesla delivered after October 15th might not ship before the beginning of next year. As Ars Technica notes, "Any new Tesla delivered after January 1st 2019 (but before July 1st 2019) is only eligible for a $3,750 IRS credit."

Like fingerprints, no 3D printer is exactly the same. That's the takeaway from a new University at Buffalo-led study that describes what's believed to be the first accurate method for tracing a 3D-printed object to the machine it came from. From the study: The advancement, which the research team calls "PrinTracker," could ultimately help law enforcement and intelligence agencies track the origin of 3D-printed guns, counterfeit products and other goods. "3D printing has many wonderful uses, but it's also a counterfeiter's dream. Even more concerning, it has the potential to make firearms more readily available to people who are not allowed to possess them," says the study's lead author Wenyao Xu, PhD, associate professor of computer science and engineering in UB's School of Engineering and Applied Sciences. [...] To understand the method, it's helpful to know how 3D printers work. Like a common inkjet printer, 3D printers move back-and-forth while "printing" an object. Instead of ink, a nozzle discharges a filament, such as plastic, in layers until a three-dimensional object forms. Each layer of a 3D-printed object contains tiny wrinkles -- usually measured in submillimeters -- called in-fill patterns. These patterns are supposed to be uniform. However, the printer's model type, filament, nozzle size and other factors cause slight imperfections in the patterns. The result is an object that does not match its design plan.

Louis Rossmann says US Customs and Border Patrol seized $1,000 worth of laptop batteries, claiming they were counterfeit. From a report: Earlier this year, Louis Rossmann, the highest-profile iPhone and Mac repair professional in the United States, told Motherboard that determining "the difference between counterfeiting and refurbishing is going to be the next big battle" between the independent repair profession and Apple. At the time, his friend and fellow independent repair pro, Jessa Jones, had just had a shipment of iPhone screens seized by Customs and Border Patrol. Rossmann was right: His repair parts were also just seized by the US government. Last month, US Customs and Border Protection (CBP) seized a package containing 20 Apple laptop batteries en route to Rossman's store in New York City. The laptop batteries were en route from China to Rossmann Repair Group -- a NYC based repair store that specializes in Apple products. "Apple and customs seized batteries to a computer that, at [the Apple Store], they no longer service because they claim it's vintage," Rossmann, the owner and operator of Rossmann Repair Group, said in a YouTube video. "They will not allow me to replace batteries, because when I import batteries that are original they'll tell me the they're counterfeit and have them stolen from by [CBP]." CBP seized the batteries on September 6, then notified Rossmann via a letter dated October 5. Rossmann produced the letter in its entirety in his video.

A new report sheds some light on the issue of paid click farms gaming Apple's long-running list of Top Podcasts. From a report: Earlier this month, Apple's long-running list of Top Podcasts began to exhibit some unusual issues -- no-name podcasts vaulting over popular, well-established ones -- but the company appeared to quickly fix its chart. Unfortunately, the problems have popped up again, and an analysis from podcast industry tracker Chartable suggests that paid click farms are now gaming the list, which it calls "the closest thing to the Billboard Top 100 in the podcast world." In theory, Apple's podcast popularity rankings might not matter -- podcasts are free, and Apple's only one source of such rankings. But after introducing its Podcast Directory in 2005, Apple became the world's largest aggregator of such programming, and its rankings serve two purposes: showing listeners what's hot, and helping advertisers determine which shows to support, thereby keeping their creators afloat. The core problem is that Apple's Top Podcasts chart appears to use a poor and easily manipulated ranking metric. Chartable believes that it's based entirely upon a podcast's total number of new subscribers over the past week, with weights assigned to movement in the past one to three days.

Slashdot's unprecedented department:
John Paczkowski and Joseph Bernstein, reporting for BuzzFeed News: Apple CEO Tim Cook, in an interview with BuzzFeed News, went on the record for the first time to deny allegations that the company was the victim of a hardware-based attack carried out by the Chinese government. And, in an unprecedented move for the company, he called for a retraction of the story that made this claim. Earlier this month Bloomberg Businessweek published an investigation alleging Chinese spies had compromised some 30 US companies by implanting malicious chips into Silicon Valley bound servers during their manufacture in China. The chips, Bloomberg reported, allowed the attackers to create "a stealth doorway" into any network running on a server in which they were embedded. Apple was alleged to be among the companies attacked, and a focal point of the story. [...] "We turned the company upside down," Cook said. "Email searches, datacenter records, financial records, shipment records. We really forensically whipped through the company to dig very deep and each time we came back to the same conclusion: This did not happen. There's no truth to this." A Bloomberg spokesperson said, "We stand by our story and are confident in our reporting and sources."

An anonymous reader shares a report: Factorising numbers into their constituent primes may sound esoteric, but the one-way nature of the problem -- and of some other, closely related mathematical tasks -- is the foundation on which much modern encryption rests. Such encryption has plenty of uses. It defends state secrets, and the corporate sort. It protects financial flows and medical records. And it makes the $2trn e-commerce industry possible. Nobody, however, is certain that the foundation of all this is sound. Though mathematicians have found no quick way to solve the prime-factors problem, neither have they proved that there isn't one. In theory, any of the world's millions of professional or amateur mathematicians could have a stroke of inspiration tomorrow and publish a formula that unravels internet cryptography -- and most internet commerce with it. In fact, something like this has already happened. In 1994 Peter Shor, a mathematician then working at Bell Laboratories, in America, came up with a quick and efficient way to find a number's prime factors. The only catch was that for large numbers his method -- dubbed Shor's algorithm -- needs a quantum computer to work. Quantum computers rely on the famous weirdness of quantum mechanics to perform certain sorts of calculation far faster than any conceivable classical machine. Their fundamental unit is the "qubit", a quantum analogue of the ones and zeros that classical machines manipulate. By exploiting the quantum-mechanical phenomena of superposition and entanglement, quantum computers can perform some forms of mathematics -- though only some -- far faster than any conceivable classical machine, no matter how beefy.

This week's FTC hearings on the growing power of companies like Amazon, Facebook, and Google only included economists who have taken money, directly and indirectly, from giant corporations that have a stake in the debate. From a report: Amid growing concern over the power of such behemoths as Amazon, Google, Facebook, and other tech giants, in recent months there's been a bipartisan push for better enforcement of antitrust rules -- with even President Trump saying in August that their size and influence could constitute a "very antitrust situation." The Federal Trade Commission (FTC) has launched its most wide-ranging study of corporate concentration in America in more than 20 years with a series of hearings being held around the country. Chairman Joseph Simons, a practical enforcement-minded leader, launched the hearings by expressing concern over the growing problem of monopoly, which is now found in nearly every sector of the economy. "I approach all of these issues with a very open mind," said Simons, "very much willing to be influenced by what I see and hear." But there's a problem. The FTC organized these hearings so that Simons and the public would be hearing from many economists who have taken money, directly or indirectly, from giant corporations. For example, on Monday, the FTC convened a panel titled "The Current Economic Understanding of Multi-Sided Platforms" to look specifically at the most dynamic and dangerous set of concentrated economic actors, the big tech platforms. Every single one of the economists who testified had financial ties to giant corporations. One example is David Evans, the chairman of the Global Economics Group. Evans scoffed at the danger of platform monopolies. He indicated that the question of "whether Facebook and Google and Amazon are monopolies, it's all interesting, it's great to read in the New York Times," but it's "not all that relevant" to the practice of antitrust. His firm has taken money directly from Microsoft, Visa, the large investment bank SIFMA, and the Chinese giant tech giant Tencent. Another example is Howard Shelanski, a partner at Davis Polk. Shelanski is more enforcement-minded, but he expressed caution, testifying that we don't know enough for antitrust enforcers to understand whether powerful technology companies hold unassailable market positions. Shelanski pointed to his own children, saying that they've stopped using Facebook because it's uncool. As it turns out, his law firm's clients include Facebook, as well as Comcast, and Chinese search giant Baidu.

Slashdot's art-of-maintenance department:
An anonymous reader shares an excerpt from The Economist: Events about making new things are ten a penny. Less common are events about keeping things as good as new. Maintenance lacks the glamour of innovation. It is mostly noticed in its absence -- the tear in a shirt, the mould on a ceiling, the spluttering of an engine. Not long ago David Edgerton of Imperial College London, who also spoke at the festival, drove across the bridge in Genoa that collapsed in August, killing 43 people (pictured). 'We're encouraged to pride ourselves on all being innovators and entrepreneurs,' he said. Maintenance is often dismissed as mere drudgery. But in fact, as he pointed out, repairing things is often trickier than making them.
It is also more difficult for economists to measure. The discipline's most prominent statistic, GDP, is gross (as opposed to net) because it leaves out the cost of wear and tear. To calculate these costs, statisticians must estimate the lifespan of a country's assets and make assumptions about the way they deteriorate. [...] And how much do economies spend fighting decay? No one knows, partly because most maintenance is performed in-house, not purchased on the market. The best numbers are collected by Canada, where firms spent 3.3% of GDP on repairs in 2016, more than twice as much as the country spends on research and development. In closing, the report mentions the tyrannies of the ancient East where people were forced to maintain fragile irrigation systems. "In those societies, to repair was to repress," the report says. "But some people today have the opposite concern. They see maintenance and repair as a right they are in danger of losing to companies that hoard spare parts and information too jealously."

In a paper published Thursday in the journal Science, Dr. Sergey Bravyi and his team reveal that they've developed a mathematical proof which, in specific cases, illustrates the quantum algorithm's inherent computational advantages over classical. Engadget reports: "It's good to know, because results like this become parts of algorithms," Bob Sutor, vice president of IBM Q Strategy and Ecosystem, told Engadget. "They become part of decisions about how people will start to attack problems. Where will they try classical techniques? Where will they try quantum techniques? How will those interplay? How will they work back and forth together?" What's more, the proof shows that, in these cases, the quantum algorithm can solve the problem in a fixed number of steps, regardless of how many inputs are added. With a classical computer, the more inputs you add, the more steps it needs to take in order to solve. Such are the advantages of parallel processing. "The main point of this paper is not that somehow we discover some incredibly important quantum algorithm, or some practical, interesting problem," Bravyi told Engadget. "We ask if we can separate a constant depth [between] quantum and classical algorithms. As we increase the problem size, the runtime of the quantum algorithm remains constant, but the total number of operations grows." As Bravyi points out, this new proof doesn't, in and of itself, solve any existing computational issues. Instead, "it gives us insight into what makes a quantum computers more powerful," he continued. "And hopefully in the future it will lead to more practical, useful algorithms."

OneHundredAndTen writes: A new article in Nature reports of a new, extremely precise measurement of the electric dipole moment of the electron. The conclusion is that, within the margin of error of the measurement, the electron remains a perfect sphere. This implies that supersymmetric theories keep running out of corners to hide, that another nail is driven into their coffin, and that string theory looks less and less compelling. By lighting up the molecules with lasers, "the scientists were able to interpret how other subatomic particles alter the distribution of an electron's charge," reports Scientific American. "The symmetrical roundness of the electrons suggested that unseen particles aren't big enough to skew electrons into squashed oblong shapes, or ovals. These findings once again confirm a long-standing physics theory, known as the Standard Model, which describes how particles and forces in the universe behave."
