The Chinese behemoth that makes electric-car batteries for Tesla and Volkswagen developed a power pack that lasts more than a million miles -- an industry landmark and a potential boon for automakers trying to sway drivers to their EV models. From a report: Contemporary Amperex Technology is ready to produce a battery that lasts 16 years and 2 million kilometers (1.24 million miles), Chairman Zeng Yuqun said in an interview at company headquarters in Ningde, southeastern China. Warranties on batteries currently used in electric cars cover about 150,000 miles or eight years, according to BloombergNEF. Extending that lifespan is viewed as a key advance because the pack could be reused in a second vehicle. That would lower the expense of owning an electric vehicle, a positive for an industry that's seeking to recover sales momentum lost to the coronavirus outbreak and the slumping oil prices that made gas guzzlers more competitive.

Apple is preparing to announce a shift to its own main processors in Mac computers, replacing chips from Intel, as early as this month at its annual developer conference, Bloomberg reported Tuesday, citing people familiar with the plans. From the report: The company is holding WWDC the week of June 22. Unveiling the initiative, codenamed Kalamata, at the event would give outside developers time to adjust before new Macs roll out in 2021, the people said. Since the hardware transition is still months away, the timing of the announcement could change, they added, while asking not to be identified discussing private plans. The new processors will be based on the same technology used in Apple-designed iPhone and iPad chips. However, future Macs will still run the macOS operating system rather than the iOS software on mobile devices from the company. Bloomberg News reported on Apple's effort to move away from Intel earlier this year, and in 2018.

An anonymous reader quotes a report from TechCrunch: Researchers at MIT have published a new paper that describes a new type of artificial brain synapse that offers performance improvements versus other existing versions, and which can be combined in volumes of tens of thousands on a chip that's smaller physically than a single piece of confetti. The results could help create devices that can handle complex AI computing locally, while remaining small and power-efficient, and without having to connect to a data center. The research team created what are known as "memristors" -- essentially simulated brain synapses created using silicon, but also using alloys of silver and copper in their construction. The result was a chip that could effectively "remember" and recall images in very high detail, repeatedly, with much crisper and more detailed "remembered" images than in other types of simulated brain circuits that have come before. What the team wants to ultimately do is recreate large, complex artificial neural networks that are currently based in software that require significant GPU computing power to run -- but as dedicated hardware, so that it can be localized in small devices, including potentially your phone, or a camera.

Unlike traditional transistors, which can switch between only two states (0 or 1) and which form the basis of modern computers, memsistors offer a gradient of values, much more like your brain, the original analog computer. They also can "remember" these states so they can easily recreate the same signal for the same received current multiple times over. What the researchers did here was borrow a concept from metallurgy: When metallurgists want to change the properties of a metal, they combine it with another that has that desired property, to create an alloy. Similarly, the researchers here found an element they could combine with the silver they use as the memristor's positive electrode, in order to make it better able to consistently and reliably transfer ions along even a very thin conduction channel. That's what enabled the team to create super small chips that contain tens of thousands of memristors that can nonetheless not only reliably recreate images from "memory," but also perform inference tasks like improving the detail of, or blurring the original image on command, better than other, previous memristors created by other scientists.

An anonymous reader shares a report: Western Digital has been receiving a storm of bad press -- and even lawsuits -- concerning their attempt to sneak SMR disk technology into their "Red" line of NAS disks. To get a better handle on the situation, ArsTechnica purchased a Western Digital 4TB Red EFAX model SMR drive and put it to the test ourselves. [...] Recently, the well-known tech enthusiast site Servethehome tested one of the SMR-based 4TB Red disks with ZFS and found it sorely lacking. The disk performed adequately -- if underwhelmingly -- in generic performance tests. But when Servethehome used it to replace a disk in a degraded RAIDz1 vdev, it required more than nine days to complete the operation -- when all competing NAS drives performed the same task in around sixteen hours.

[...] We want to be very clear: we agree with Seagate's Greg Belloni, who stated on the company's behalf that they "do not recommend SMR for NAS applications." At absolute best, SMR disks underperform significantly in comparison to CMR disks; at their worst, they can fall flat on their face so badly that they may be mistakenly detected as failed hardware. With that said, we can see why Western Digital believed, after what we assume was a considerable amount of laboratory testing, that their disks would be "OK" for typical NAS usage. Although obviously slower than their Ironwolf competitors, they performed adequately both for conventional RAID rebuilds and for typical day-to-day NAS file-sharing workloads. We were genuinely impressed with how well the firmware adapted itself to most workloads -- this is a clear example of RFC 1925 2.(3) in action, but the thrust does appear sufficient to the purpose. Unfortunately, it would appear that Western Digital did not test ZFS, which a substantial minority of their customer base depends upon.

Battery-powered bikes "have become a compelling alternative for commuters who are being discouraged from taking public transportation and Ubers," according to the New York Times' lead consumer tech writer. In March, sales of e-bikes jumped 85% from a year earlier, according to the NPD Group, a research firm. Amazon, Walmart and Specialized are sold out of most models. Even smaller brands like Ride1Up and VanMoof have waiting lists. That's a remarkable shift. For many years, e-bikes carried the stigma of being vehicles for lazy pedalers and seniors... "I was convinced that e-bikes would completely change cities all over the world in the next 10 years, but it seems like because of this crisis, suddenly it's all happening in the next three or four months," said Taco Carlier, the chief executive of VanMoof, which is based in Amsterdam.
The Times' writer notes that e-bikes are at least twice as heavy as a road bike, make an attractive target for burglar, and may need manufacturer assistance for major repairs. But he ultimately concludes that "Despite some misgivings, my experience with e-bikes made me realize the benefits are far greater than the downsides." Most important, e-bikes kept me out of my car. Whenever I had a reason to go outside — like making a trip to the grocery store or dropping off baked goods at a friend's — I preferred riding an e-bike. This will become increasingly important in the coming months. As businesses reopen, the Centers for Disease Control and Prevention has advised commuters to drive in cars alone. An e-bike may become crucial for squeezing through nightmare traffic.
And the Times' reporter also claims another benefit for e-bikes: joy. "On an e-bike, I saw more of the outdoors than I normally would, while keeping a safe distance from people."

"It's the middle of 2020 and the USB-C standards are confusing even for the most technical person," writes Slashdot reader mprindle. Robert Triggs writes via Android Authority: USB-C is billed as the solution for all our future cable needs, unifying power, and data delivery with display and audio connectivity. Ushering in an age of the one-size-fits-all cable. Despite the USB-C connector supplied as default in modern smartphones, the standard has, unfortunately, failed to live up to its early promises. Even the seemingly most basic function of USB-C -- powering devices -- continues to be a mess of compatibility issues, conflicting proprietary standards, and a general lack of consumer information to guide purchasing decisions. The data speeds available over USB-C have also become increasingly convoluted. The problem is that the features supported by different USB-C devices aren't clear, yet the defining principle of the USB-C standard makes consumers think everything should just work... The article goes on to discuss the charging speed and data transfer speed disparities, USB-C port shortages, and compatibility issues with USB 2.0, 3.0, and 3.1 cables.

"Unfortunately, the USB-C ecosystem is more, not less convoluted in 2020 than it was when I first looked at this issue back in 2018," writes Robert Triggs in closing. "The announcement of USB 3.2 and USB 4 makes the standard more complex without giving the end-user clear information about what's supported. While the growth in USB Power Delivery support is a good sign, the introduction of PPS has already hampered any hopes that the industry might soon coalesce around a single charging standard. The USB spec changes every year, making it impossible for consumers to keep up. Years later, I still don't see a clear way out of this confusing mess."

The Apple Watch's Fall Detection feature is being credited as helping save an unresponsive man in Chandler, Arizona. AppleInsider reports: Fall Detection, introduced on the Apple Watch Series 4, can detect if a user takes a hard fall and will alert local emergency services if they don't respond within 60 seconds. The potentially life-saving capabilities of that feature were on display on April 23, when police dispatchers in Chandler received a 911 call from an automated voice, according to local media outlet KTAR. The auto-generated message indicated that an Apple Watch wearer had fallen and was not responding, and also provided authorities with the exact latitude and longitude of the man's location. When officers and the Chandler Fire Department showed up, they found that the man had fainted and collapsed.

Maddie Stone, writing for OneZero: For the past eight years, I've been working mainly on a late 2012 iMac. I'm no Luddite, but the computer has held up well over the years, and I've never felt the need to replace it. Recently, though, my iMac developed its first serious tic: The fan has started to power on loudly every time the computer goes to sleep. While the computer is long past warranty, I decided to call up Apple to see if the company could offer any help. When I did, I learned my iMac is considered "vintage" and was told Apple won't touch it. [...] According to Apple, "vintage" devices are those that the company discontinued selling more than five and less than seven years ago. Once Apple hasn't sold a product for seven years, it's considered "obsolete," meaning the company won't offer any repair services. But vintage products exist in a liminal space: Despite what I learned when I called Apple Support, Apple Stores as well as AASPs (Apple Authorized Service Provide) can, in theory, repair them for you "subject to availability of inventory, or as required by law," according to Apple.

In practice, people in the repair community told me Apple isn't particularly interested in fixing vintage tech. "The AASPs I've spoken to in the past have told me they don't bother with customers looking to repair older devices," said Rob Link, a right-to-repair advocate who owns a company that sells repair parts for older devices including iPhones, iPods, and iPads. In the past, Link said, he would call up AASPs to see if they had older parts to sell "but I would stop when no one did." "If you're taking in a vintage piece of equipment [to an AASP], outside of them still having something sitting on the shelf from years before, you're not going to be able to get service," said Adrian Avery-Johnson, the owner of Bridgetown Electronics Repair, an independent repair shop located in Portland, Oregon.

An anonymous reader quotes a report from Reuters: France and Germany threw their weight on Thursday behind plans to create a cloud computing ecosystem that seeks to reduce Europe's dependence on Silicon Valley giants Amazon, Microsoft and Google. The project, dubbed Gaia-X, will establish common standards for storing and processing data on servers that are sited locally and comply with the European Union's strict laws on data privacy. German Economy Minister Peter Altmaier, speaking in Berlin, described Gaia-X as a "moonshot" that would help reassert Europe's technological sovereignty, and invited other countries and companies to join. "We are not China, we are not the United States, we are European countries with our own values and with our own economic interest that we want to defend," his French counterpart Bruno Le Maire said in Paris in a joint video news conference.

In an initial step, 22 French and German companies will set up a non-profit foundation to run Gaia-X, which is not conceived as a direct rival to the "hyperscale" U.S. cloud providers but would instead referee a common set of European rules. "Building a European-based alternative is possible only if we play collectively," said Michel Paulin, CEO of independent French cloud service provider OVHcloud. One important concept underpinning Gaia-X is "reversibility," a principle that would allow users to easily switch providers. First services are due to be offered in 2021.

An anonymous reader quotes a report from The Guardian: A new study published in Scientific Reports reveals that crystalline rocks, such as granite, have a natural self-sealing mechanism, capable of keeping fluids locked away for millions of years. Careful analysis of the chemistry and structure of granites from Japan and the UK revealed that when fluid did enter the rock (via fractures), it travelled a few centimeters at most. The scientists believe that calcium in the rock reacted with carbonate in the fluid to create tiny crystals of calcite that plugged all the gaps and prevented further flow. "This amount of calcite would never be expected in a granite, and the distribution of it indicates it almost certainly formed from small quantities of fluid trying to move through the rock," says Roy Wogelius from the University of Manchester. Greater understanding is needed before we finalize our radioactive waste disposal strategies, but this is a promising step forward.

Dyson has revealed new photos and information about their failed electric SUV, which the company canceled last October due to high costs. The Verge reports: In a new blog post on his company's website, Dyson shows off some of the first images and videos of the real prototype it made before the project was killed last October, as well as a few more computer renderings. He describes the SUV as "a radical car which was loaded with technology," and says his company "solved lots of problems that are traditionally associated with electric vehicles," though the project was ultimately abandoned for not being "commercially viable." Missing from the post is any substantive explanation of what those problems were, though, or how the company was going to solve them. Dyson touts a "spoke, integrated and highly efficient Electric Drive Unit (EDU) comprising Dyson digital electric motor, single speed transmission and state of the art power inverter," though there's no explanation about what sets those technologies apart from the ones developed by other companies in the electric vehicle space.

Other listed design benefits (like a flexible battery pack design, improved interior space, longer wheelbase) and features (like a heads-up display or handle-free doors) are also far from unique. And while Autocar reports that the SUV was supposed to offer somewhere around 600 miles of range using a 150kWh battery, Dyson never got close enough to put that claim to the test. One of the few standout parts of the SUV is the steering wheel, which looks more like a video game controller than anything.

Following the rioting and looting from the death of George Floyd, Apple has a message for those who power on a stolen iPhone: "This device has been disabled and is being tracked. Local authorities will be alerted." Forbes reports: Apple CEO Tim Cook sent a message to his employees as those protests escalated, saying that "there is a pain deeply etched in the soul of our nation and in the hearts of millions. To stand together, we must stand up for one another, and recognize the fear, hurt, and outrage rightly provoked by the senseless killing of George Floyd and a much longer history of racism." Cook went on to say that "at Apple, our mission has and always will be to create technology that empowers people to change the world for the better. We've always drawn strength from our diversity, welcomed people from every walk of life to our stores around the world, and strived to build an Apple that is inclusive of everyone."

These words were being digested as the tech giant made the decision to close the majority of its U.S. stores for the safety of those staff and its customers, stores that had only just reopened after the COVID-19 shutdown. Apple has unsurprisingly become a favored target of looters, given the likely spoils on offer, and the decision was taken to remove stock from shop floors and shutter locations. It has long been known that Apple operates some form of proximity software that disables a device when it is taken illegally from a store. Until now, though, little had been seen of that technology in action. Well, thanks to social media, we can now see the message that greets a looter powering up their new device: "This device has been disabled and is being tracked," it says. "Local authorities will be alerted."

MojoKid writes: AI and Machine Learning performance benchmarks have been well explored in the data center, but are fairly new and unestablished for edge devices like smartphones. While AI implementations on phones are typically limited to inferencing tasks like speech-to-text transcription and camera image optimization, there are real-world neural network models employed on mobile devices and accelerated by their dedicated processing engines. A deep dive look at HotHardware of three popular AI benchmarking apps for Android shows that not all platforms are created equal, but also that performance results can vary wildly, depending on the app used for benchmarking.

Generally speaking, it all hinges on what neural networks (NNs) the benchmarks are testing and what precision is being tested and weighted. Most mobile apps that currently employ some level of AI make use of INT8 (quantized). While INT8 offers less precision than FP16 (Floating Point), it's also more power-efficient and offers enough precision for most consumer applications. Typically, Qualcomm Snapdragon 865 powered devices offer the best INT8 performance, while Huawei's Kirin 990 in the P40 Pro 5G offers superior FP16 performance. Since INT8 precision for NN processing is more common in today's mobile apps, it could be said that Qualcomm has the upper hand, but the landscape in this area is ever-evolving to be sure.

It's no secret that 5G networks drain battery. "To rectify that grim side effect, researchers at the University of Texas at Austin and the University of Lille in France have developed a new radio-frequency switch they say is 50 times more energy efficient than the current solid-state switches," reports Popular Mechanics. From the report: The solution is actually rooted right in the problem. Because smartphones are packed with switches that perform duties like hopping back and forth between different networks and spectrum frequencies (4G to LTE, to WiFi, to Bluetooth, etc.), batteries drain much faster. State-of-the-art radio-frequency switches are constantly running in the background on your iPhone or Android device, consuming not only battery life, but processing power. So when the limited number of 5G-enabled smartphones on the market are constantly bouncing back and forth between 4G and 5G communications, for instance, the problem is amplified.

"The switch we have developed can transmit an HDTV stream at a 100GHz frequency, and that is an achievement in broadband switch technology," lead researcher Deji Akinwande, a professor at the University of Texas at Austin, said in a prepared statement. And the premise is simple: the switches stay off most of the time. Unless the radio-frequency switches are actively helping the device jump between networks at that precise point in time, they stay off, preserving precious battery life for other processes.

To build it, the scientists used a nanomaterial called hexagonal boron nitride, a newcomer in the materials science field that comes from the same family as graphene, a honeycomb-lattice sheet of carbon atoms used in everything from bike tires to cleaning up radioactive waste. According to research in Semiconductors and Semimetals, hexagonal boron nitride is only as thick as a single layer of atoms and is the thinnest known insulator in the world, with a thickness of 0.33 nanometers (for comparison's sake, a human hair is about 100,000 nanometers thick). In this case, these scientists used a single layer of boron and nitrogen atoms in a honeycomb pattern. Then, they sandwiched the layers between a set of gold electrodes. The findings have been published in the journal Nature Electronics.

An anonymous reader quotes a report from Forbes: Last week the Energy Information Administration (EIA) reported something extraordinary. For the first time in 135 years, last year U.S. consumption of renewables surpassed consumption of coal. There are two interrelated reasons for this: The collapse of coal consumption over the past decade, which was fueled by the rise of cheaper alternatives. I have covered the reasons for coal's collapse previously. The short version is that policies to curb carbon emissions were put in place about the same time the shale boom and renewable power revolutions created cheaper, cleaner alternatives to coal. The graphic above shows the surge in renewables that helped collapse coal demand. This surge is better shown by the following graphic, which highlights the three categories of modern renewables that have driven the consumption surge: Wind power, solar power, and biofuels. The report points out that fossil fuels still dominate our energy consumption. "Last year the U.S. consumed 11.3 quadrillion BTUs (quads) of coal and 11.5 quads of renewables," adds Forbes. "But we also consumed 36.7 quads of petroleum and 32.1 quads of natural gas. Each of these categories of fossil fuel consumption was greater than our combined consumption of renewables and coal, which provides a broader perspective on our energy consumption."

"In total, the U.S. consumed 80.5 quads of fossil fuels, 11.5 quads of renewables, and 8.5 quads of nuclear power. Renewables represented 11.4% of U.S. energy consumption in 2019, versus 8.1% a decade ago."

Robotic hands capable of picking up objects as fragile as a crisp by "sensing" objects have been developed by researchers. The Independent reports: Two new tools built by MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) offer a breakthrough in the emerging field of soft robotics -- a new generation of robots that use squishy, flexible materials rather than traditional rigid equipment." These types of soft robots often draw inspiration from living organisms and offer numerous benefits in their versatile functionality. They are able to operate far more delicately than their rigid counterparts, but until now they have lacked the ability to perceive what items they are interacting with. To overcome this, the researchers equipped their robots with various sensors, cameras and software, allowing them to "see and classify" a range of objects.

The first robot built of research from MIT and Harvard University in 2019, where a team developed a robotic gripper in the shape of a cone. It worked by collapsing in on an object in a similar way to a Venus flytrap, allowing it to pick up a range of awkwardly shaped objects up to 100-times its weight. By adding tactile sensors, the robot was able to understand what it was picking up and adjust the amount of pressure exerted accordingly. Of the 10 objects used in the experiment, the sensors were able to identify them with an accuracy rate of more than 90 percent. The second robot made use of an innovative "GelFlex" finger, which uses a tendon-driven mechanism and an array of sensors to provide "more nuanced, human-like senses." The team now hopes to fine-tune the sensing algorithms and introduce more complex finger configurations, such as twisting.

When Dutch restaurants open tomorrow, one will be using two shiny white-and-red robot waiters, reports the Associated Press: "Hello and welcome," the robots say — in a voice best described as pre-programmed. Their duties will include greeting customers, serving drinks and dishes and returning used glasses and crockery. It's unclear whether diners will be expected to tip.

One thing the robots will certainly do is see that social distancing rules are respected. "We will use them to make sure the five feet we need during the corona crisis sticks," Leah Hu said. "I've had negative reactions," she said, "such as saying it makes it impersonal." But it may prove just what customers crave when Dutch restaurants are allowed to reopen Monday as lockdown restrictions are further eased.

In a stab at quasi-human panache, one robot wears a chiffon scarf around its neck....

And in the southern Zeeland province, the Hus don't want to hear any complaints about the robots robbing young people of a job. They say it's hard enough anyway to find staff in a rural region without any major city close by... "We are often busy and cleaning tables and the robots give us an extra hand." It also frees up the human staff for some more personal contact. "We are not disappearing. We are still here. They will always need people in this industry," she said.

AMD "has a potent combination of both CPU and GPU technologies," writes Slashdot reader MojoKid, that "can play well in the laptop market especially, where a tight coupling of the two processing engines can mean both performance and cost efficiencies." One of the first all-AMD laptops to hit the market powered by the company's new Ryzen 4000 mobile processors is the Dell G5 15 SE, it's a 5.5 pound, 14.4-inch machine [with a 15.6-inch display] that sports an understated design for a gaming notebook but with an interesting glittery finish that resists fingerprints well. With a retail price of $1199 (starting at $879), the model tested at HotHardware is powered by an AMD Ryzen 4800H 8-core processor that boosts to 4.2GHz and an AMD Radeon RX 5600M mobile GPU with 6GB of GDDR6 memory...

In the benchmarks, AMD's SmartShift technology load-balances CPU and GPU power supply for optimal performance and very respectable numbers that are competitive with any similar Intel/NVIDIA powered machine. The Dell G5 15 SE put up north of 60 FPS frame rates at maximum image quality in current-gen game titles, but with a significantly better price point, relatively speaking.
The GPU also has 2,304 stream processors across 36 compute units, and "Overall, we think Dell hit it out of the park with the new G5 15 SE," the review concludes.

"This all-AMD budget blockbuster has all of the gaming essentials: a fast processor, a powerful GPU, and a 144 Hz display."

An anonymous reader quotes a report from Ars Technica: All three of the surviving conventional hard drive vendors -- Toshiba, Western Digital, and Seagate -- have gotten caught sneaking disks featuring Shingled Magnetic Recording technology into unexpected places recently. But Western Digital has been the most brazen of the three, and it's been singled out for a class action lawsuit in response. Although all three major manufacturers quietly added SMR disks to their desktop hard drive line-up, Western Digital is the only one so far to slip them into its NAS (Network Attached Storage) stack. NAS drives are expected to perform well in RAID and other multiple disk arrays, whether ZFS pools or consumer devices like Synology or Netgear NAS appliances.

Hattis Law has initiated a class action lawsuit against Western Digital, accordingly. The lawsuit alleges both that the SMR technology in the newer Western Digital Red drives is inappropriate for the marketed purpose of the drives and that Western Digital deliberately "deceived and harm[ed] consumers" in the course of doing so. Hattis' position is strengthened by a series of tests that website ServeTheHome released yesterday. The results demonstrate that although Western Digital's new 4TB Red "NAS" disk performed adequately as a desktop drive, it was unfit for purpose in a ZFS storage array (zpool).

"Amazon is discontinuing its Echo Look camera, a standalone device that gave owners fashion advice using artificial intelligence and machine learning," reports The Verge. The gadget raised eyebrows when it was first announced as it included a virtual assistant with a microphone and a camera specifically designed to go somewhere in your bedroom, bathroom, or wherever the hell you get dressed. From the report: The Look's companion app and the device itself will stop functioning on July 24th. Between now and July 24th, 2021, Look users can back up their images and videos by making a free Amazon Photos account. (People with existing Photos accounts will have their media backed up automatically.) Anyone who wants to delete all their existing photos and videos will have to do so before the July 2020 deadline; otherwise, they'll have to call Amazon's customer service to have them deleted. They can currently delete them through the Look app.

Amazon points out that much of the Echo Look's functionality is now included in the Amazon Shopping app, including Style by Alexa, which involves the AI offering fashion pointers. The company says people should download the app to keep consulting with Amazon, and they should also recycle their Look through Amazon's program.
