Ben Jervey from DeSmogBlog writes about how Toyota is "using questionable logic" to claim hybrid vehicles are superior than electric vehicles, when in reality it's only saying that because it decided years ago to invest in gasoline-electric hybrids and fuel cells in the long term instead of battery production. This decision is now coming back to haunt them. From the report: There are at least 12 car companies currently selling an all-electric vehicle in the United States, and Toyota isn't one of them. Despite admitting recently that the Tesla Model 3 alone is responsible for half of Toyota's customer defections in North America -- as Prius drivers transition to all-electric -- the company has been an outspoken laggard in the race to electrification. Now, the company is using questionable logic to attempt to justify its inaction on electrification, claiming that its limited battery capacity better serves the planet by producing gasoline-electric hybrids. For years, Toyota leadership has shunned investment in all-electric cars, laying out a more conservative strategy to "electrify" its fleet -- essentially doubling down on hybrids and plug-in hybrids -- as a bridge to a future generation of hydrogen fuel cell vehicles. As Tesla, Nissan, and GM have led the technological shift to fully battery electric vehicles, Toyota has publicly bashed the prospects of all-electric fleets. (See, for instance, the swipe the company took at plug-in vehicles in this recent Toyota Corolla Hybrid commercial.)

Last week, at the Geneva Auto Show, a Toyota executive provided a curious explanation for the company's refusal to launch a single battery electric vehicle. As Car and Driver reported, Toyota claims that it is limited by battery production capacity and that "Toyota is able to produce enough batteries for 28,000 electric vehicles each year -- or for 1.5 million hybrid cars." In other words, because Toyota has neglected to invest in battery production, it can only produce enough batteries for a trivial number of all-electric vehicles. Due to this self-inflicted capacity shortage, the company is forced to choose between manufacturing 1.5 million hybrids or 28,000 electric cars. Using what Car and Driver called "fuzzy math," the company tried to justify the strategy to forgo electric vehicles (EVs) on environmental grounds. As Toyota explained it, "selling 1.5 million hybrid cars reduces carbon emissions by a third more than selling 28,000 EVs." As for the "fuzzy math," Toyota's calculation "seems to assume that for every hybrid sold, a fully gasoline-powered car would be taken off the road," writes Jervey. "In reality, many Toyota hybrid buyers are replacing a Toyota hybrid. And, based on Toyota's own revelation that they are losing Prius drivers to Tesla, it stands to reason that many Toyota hybrid drivers would jump at the opportunity to transition to an all-electric Toyota."

According to a report from Yonhap News Agency, Samsung's vice president of its display R&D group, Yang Byung-duk, said the company is working on making the entire front of its phones a screen, with no need for bezels or a camera cutout of any kind. He said that "though it wouldn't be possible to make (a full-screen smartphone) in the next 1-2 years, the technology can move forward to the point where the camera hole will be invisible, while not affecting the camera's function in any way." The Verge reports: The comments come less than a month after Samsung announced its latest flagship, the Galaxy S10, which is the company's first phone to have a "hole-punch" cut out from its display for the selfie camera. Yang called the S10's Infinity-O display a "milestone" for the company, but suggested that Samsung eventually plans to place the selfie camera under the display itself, removing the need for any cut out or pop-up mechanism.

An anonymous reader quotes a report from Motherboard: Now, for Pi Day (March 14), music software programmer Canton Becker has crafted a million-hour song based on Pi that unfolds generatively on a virtual tape deck. Titled "Shepard's Pi," the song combines two of Becker's favorite infinities: Pi, and an auditory illusion called a Shepard tone, which he describes as an "unsettling sonic illusion of a pitch that climbs or descends forever, never reaching a top or a bottom." Found at PiSongs.com, users can tune into "Shepard's Pi" in real time with a custom virtual tape deck. The track itself evolves moment to moment, but the synthesized and sampled tones will be familiar to anyone who has ever listened to the electronic music of Kraftwerk, Tangerine Dream, Aphex Twin, and Global Communication. Far from being a mere gimmick, it is a highly evocative and transporting piece of electronic music, alternately ambient, glitchy, and interestingly rhythmic. The 58,999 GB MP3 file needed to be distributed via a webpage or app, so Becker "started hacking away at the basic algorithm in the programming languages PHP and Javascript," reports Motherboard. "In between coding marathons, Becker composed and recorded the loops and samples that would form the basis of the song. He experimented with sounds that would work well together regardless of being stacked one upon the other."

"When users hit 'play' on the virtual tape deck, the algorithm actually 'performs' the piece," the report says. "This way, the 114-year song can fit in just one gigabyte of space, which is mostly comprised of the digits of Pi. The virtual tape deck was also a solution to a built-in quirk of browsers such as Chrome, Safari, and Firefox -- users must click on a webpage to trigger a sound." From start to finish, the song lasts 999,999 hours, "a limitation imposed by only considering the first one billion digits of Pi."

MojoKid writes: NVIDIA took the wraps off yet another lower cost Turing-based graphics card today, dubbed the GeForce GTX 1660. For a $219 MSRP, the card offers a cut-down NVIDIA TU116 GPU comprised of 1408 CUDA cores with a 1785MHz boost clock and 6GB of GDDR6 RAM with 192.1GB/s of bandwidth. Generally speaking, the new GeForce GTX 1660 is 15% to 30% faster than NVIDIA's previous generation GeForce GTX 1060 but doesn't support new ray tracing and DLSS features that the majority of NVIDIA's new Turing cards support. Performance-wise, GeForce GTX 1660 is generally faster than an AMD Radeon RX 590 overall. Boards from various OEM partners should be in the channel for purchase this week.

Microsoft is bringing its Xbox Live network to iOS and Android devices. "The software giant is launching a new cross-platform mobile software development kit (SDK) for game developers to bring Xbox Live functionality to games that run on iOS and Android," reports The Verge. "Xbox Live features like achievements, Gamerscore, hero stats, friend lists, clubs, and even some family settings will all be available on iOS and Android." From the report: It's all part of a bigger push from Microsoft to make its Xbox games and services available across multiple platforms. Game developers will be able to pick and choose parts of Xbox Live to integrate into their games, and it will all be enabled through a single sign-in to a Microsoft Account. Microsoft is using its identity network to support login, privacy, online safety, and child accounts. Microsoft wants game developers to take a similar Minecraft approach and bring Xbox Live to more mobile games. Some iOS and Android games already have Xbox Live Achievements, but they're only enabled in titles from Microsoft Studios at the moment and this new SDK will open up Xbox Live functionality to many more games.

If you were hoping to see Xbox Live on Nintendo Switch then you might have to wait a little longer. "Our goal is to really unite the 2 billion gamers of the world and we're big fans of our Xbox Live community, but we don't have any specific announcements as it relates to Switch today," reveals Choudhry. Xbox Live on PlayStation 4 also looks unlikely, but Microsoft is open to the idea if Sony is willing to allow it. "If you've watched us for the past few years, we've taken a very inclusive approach," says Choudhry. "Phil [Spencer] has been very proactive on issues like crossplay, cross-progression, and uniting gamer networks, and we're willing to partner with the industry as much as we possibly can."

An anonymous reader quotes a report from Ars Technica: The Federal Aviation Administration issued an emergency order grounding all Boeing 737 MAX aircraft on March 13, citing new data that showed a possible link between the March 10 crash of an Ethiopian Airlines flight and the crash of a Lion Air flight off the coast of Indonesia last October. In an interview with NPR's David Greene this morning, acting FAA Director Dan Ewell said that "newly refined satellite data" from a flight telemetry system had led the agency to make the move. Both Ethiopian Airlines Flight 302 (ET302) and Lion Air Flight 610 (JT610) were recently acquired 737 MAX 8 aircraft, and both were lost with all aboard just minutes after take-off. According to the emergency order issued by the FAA, "new information from the wreckage concerning the aircraft's configuration just after takeoff that, taken together with newly refined data from satellite-based tracking of the aircraft's flight path, indicates some similarities between the ET302 JT610 accidents that warrant further investigation of the possibility of a shared cause for the two incidents that needs to be better understood and addressed."

The source of the data in question is a combination of telemetry feeds from the flights' Automatic Dependent Surveillance(ADS) system. Introduced in the US in 2001 and more widely worldwide in the wake of the crash of Malaysian Airlines flight 370 in 2014, Europe has required most aircraft to carry the UHF-band ADS-Broadcast (ADS-B) system since 2017, and the FAA has mandated ADS-B for most aircraft by 2020. While ADS-B data was initially meant to be picked up by other aircraft and ground stations, it is also tracked by satellites. Other, less-granular telemetry data sent in the subscription-based ADS-addressed/Contract (ADS-A/ADS-C) format, the Future Air Navigation System(FANS), and the Aircraft Communications Addressing and Reporting System (ACARS) are also picked up by satellite.

An anonymous reader shares a report: As more and more laptops find their way into middle and high schools, educators are using Google Docs to do collaborative exercises and help students follow along with the lesson plan. The students, however, are using it to organize running conversations behind teachers' backs. Teens told me they use Google Docs to chat just about any time they need to put their phone away but know their friends will be on computers. Sometimes they'll use the service's live chat function, which doesn't open by default, and which many teachers don't even know exists. Or, they'll take advantage of the fact that Google allows users to highlight certain phrases or words, then comment on them via a pop-up box on the right side: They'll clone a teacher's shared Google document, then chat in the comments, so it appears to the causal viewer that they're just making notes on the lesson plan. If a teacher approaches to take a closer look, they can click the "Resolve" button and the entire thread will disappear.

If the project isn't a collaborative one, kids will just create a shared document where they'll chat line by line in what looks like a paragraph of text. "People will just make a new page and talk in different fonts so you know who is who," Skyler said. "I had one really good friend and we were in different homerooms. So, we'd email each other a doc and would just chat about whatever was going on." At the end of class, they just delete a doc or resolve all the comments. Rarely does anyone save them the way previous generations may have stored away paper notes from friends.

An anonymous reader shares a report: Pilots now spend more time learning automated systems than practicing hands-on flying, so newer pilots are less comfortable with taking manual control when the computer steers them wrong, according to interviews with a dozen pilots and pilot instructors at major airlines and aviation universities around the world. "The automation in the aircraft, whether it's a Boeing or an Airbus, has lulled us into a sense of security and safety," said Kevin Hiatt, a former Delta Air Lines pilot who later ran flight safety for JetBlue. Pilots now rely on autopilot so often, "they become a systems operator rather than a stick-and-rudder pilot."

As a result, he said, "they may not exactly know or recognize quickly enough what is happening to the aircraft, and by the time they figure it out, it may be too late." [...] While automation has contributed to the airline industry's stellar safety record in recent years, it has also been a factor in many of the crashes that have still occurred around the world. A 2011 study by a federal task force found that in about 60 percent of 46 recent accidents, pilots had trouble manually flying the plane or handling the automated controls. Complicated automation systems can also confuse pilots and potentially cause them to take action they shouldn't, pilots said.

Facebook is sorry: The social media giant apologized for the technical errors that left many users globally unable to access apps for Facebook, Instagram, Messenger and WhatsApp starting Wednesday and stretching into Thursday, and said it's fixed the glitch. From a report: About 24 hours after users began reporting problems with Facebook, Instagram and other apps, Facebook announced Thursday -- on Twitter -- that it had resolved them and that its systems are "recovering." "Yesterday, as a result of a server configuration change, many people had trouble accessing our apps and services. We've now resolved the issues and our systems are recovering," the company said in a tweet. "We're very sorry for the inconvenience and appreciate everyone's patience."

physburn writes: The Register has spoken to some experts to get a better understanding of the risk quantum computers present to the existing encryption systems we have today. Richard Evers, cryptographer for a Canadian security biz called Kryptera, argues that media coverage and corporate pronouncements about quantum computing have left people with the impression that current encryption algorithms will soon become obsolete. But they will not be ready for at least 10 years, he said. As an example, Evers points to remarks made by Arvind Krishna, director of IBM research, at The Churchill Club in San Francisco last May, that those interested in protecting data for at least ten years "should probably seriously consider whether they should start moving to alternate encryption techniques now." In a post Evers penned recently with his business partner Alastair Sweeny, he contends, "The hard truth is that widespread beliefs about security and encryption may prove to be based on fantasy rather than fact." And the reason for this, he suggests, is the desire for funding and fame.

Tumblr's ban on pornography and adult content has led to an estimated fifth of its users deserting the platform. From a report: Tumblr's ban on pornography and adult content has led to a fifth of its users deserting the platform, figures reveal. The ban, which came into effect on 17 December, provoked a backlash from users who claimed it would penalise sex-positive, LGBT and NSFW art communities. Visits to the Tumblr website fell from 521 million in December to 437 million in January and 370 million in February, according to data from web analytics firm SimilarWeb. Tumblr's decision to update its content policy came after the discovery of child sexual abuse imagery on its blogs.

Dropbox has quietly removed unlimited device linking for free accounts, meaning that unless you upgrade to one of its paid plans, which start at $8.25 per month, you will be restricted to three devices for a single account. From a report: The change was rolled out earlier this month, though it's worth noting that those who had linked more than three devices prior to March 2019 won't be directly affected. However, anyone who already exceeds the new limit will be impacted at some point, as they won't be able to add any more devices to their account in the future, and if they upgrade to a new phone, tablet, or computer, the three device limit will catch up with them.

Pi just got bigger. Google's Compute Engine has calculated the most digits of pi ever, setting a new world record. From a report: Emma Haruka Iwao, who works in high performance computing and programming language communities at Google, used infrastructure powered by Google Cloud to calculate 31.4 trillion digits of pi. The previous world record was set by Peter Trueb in 2016, who calculated the digits of pi to 22.4 trillion digits. This is the first time that a publicly available cloud software has been used for a pi calculation of this magnitude.

Iwao became fascinated by pi when she learned about it in math class at school. At university, one of her professors, Daisuke Takahashi, was the record holder for the most-calculated digits of pi using a supercomputer. Now, y-cruncher is the software of choice for pi enthusiasts. Created in 2009, y-cruncher is designed to compute mathematical constants like pi to trillions of digits. "You need a pretty big computer to break the world record," says Iwao. "But you can't just do this with a computer from a hardware store, so people have previously built custom machines." In September of 2018, Iwao started to consider how the process of calculating even more digits of pi would work technically. Something which came up quickly was the amount of data that would be necessary to carry out the calculations, and store them -- 170 terabytes of data, which wouldn't be easily hosted by a piece of hardware. Rather than building a whole new machine Iwao used Google Cloud.

Iwao used 25 virtual machines to carry out those calculations. "But instead of clicking that virtual machine button 25 times, I automated it," she explains. "You can do it in a couple of minutes, but if you needed that many computers, it could take days just to get the next ones set up." Iwao ran y-cruncher on those 25 virtual machines, continuously, for 121 days.

An anonymous reader quotes a report from The New York Times: Federal prosecutors are conducting a criminal investigation into data deals Facebook struck with some of the world's largest technology companies (Warning: source may be paywalled; alternative source), intensifying scrutiny of the social media giant's business practices as it seeks to rebound from a year of scandal and setbacks. A grand jury in New York has subpoenaed records from at least two prominent makers of smartphones and other devices, according to two people who were familiar with the requests and who insisted on anonymity to discuss confidential legal matters. Both companies had entered into partnerships with Facebook, gaining broad access to the personal information of hundreds of millions of its users. The companies were among more than 150, including Amazon, Apple, Microsoft and Sony, that had cut sharing deals with the world's dominant social media platform. The agreements, previously reported in The New York Times, let the companies see users' friends, contact information and other data, sometimes without consent. Facebook has phased out most of the partnerships over the past two years. "We are cooperating with investigators and take those probes seriously," a Facebook spokesman said in a statement. "We've provided public testimony, answered questions and pledged that we will continue to do so."

DarkRookie2 shares a report from Ars Technica: After a seemingly endless run of rumors, the news Halo fans have been waiting for is here: the series is finally coming back to PC, and in pretty big fashion. Halo: The Master Chief Collection will arrive on Windows PCs "later this year," according to the official Halo Waypoint site, and fans will be able to buy the collection either via Steam or the Windows Store. (Anybody who's dealt with Windows 10's UWP woes will appreciate this rare example of Microsoft launching one of its first-party games on Steam at the same time as Windows Store, as opposed to delaying a Steam version for a few months.)

The game's listing confirms that PC gamers can look forward to full mouse-and-keyboard control support, along with support for resolutions up to 4K and an HDR toggle. Whether this version will also include the kinds of tweaks that hardcore PC gamers crave -- including ultra-widescreen ratios, higher frame rates, and fully remappable controls -- remains to be seen. We highly doubt Microsoft will include official mod support beyond letting players use individual games' built-in "Forge" creation tools. Halo Reach will also join the MCC when it launches on PC. Unfortunately, there's no word on cross-platform play.

pgmrdlm shares a report from CNN: Last May, Opportunity took a look around Perseverance Valley on the inner slope of Endurance Crater's western rim. The valley is about the length of two football fields and it's full of descending shallow troughs. Ironically, Perseverance Valley became Opportunity's final resting place when a planet-encircling dust storm took over Mars in June, blocking the sun from reaching the rover's solar panels. Engineers lost contact on June 10 and persistently sent more than a thousand signals and commands to the rover over eight months until they realized the mission was over on February 13. But before those dark days, Opportunity acted like a tourist, snapping 354 photos between May 13 and June 10 that would create one last beautiful panorama of the place it will forever call home. "This final panorama (embedded in the report) embodies what made our Opportunity rover such a remarkable mission of exploration and discovery," said Opportunity project manager John Callas of NASA's Jet Propulsion Laboratory. "To the right of center you can see the rim of Endeavour Crater rising in the distance. Just to the left of that, rover tracks begin their descent from over the horizon and weave their way down to geologic features that our scientists wanted to examine up close. And to the far right and left are the bottom of Perseverance Valley and the floor of Endeavour crater, pristine and unexplored, waiting for visits from future explorers."

fahrbot-bot shares a report from Phys.Org: Researchers from the Moscow Institute of Physics and Technology teamed up with colleagues from the U.S. and Switzerland and returned the state of a quantum computer a fraction of a second into the past. They also calculated the probability that an electron in empty interstellar space will spontaneously travel back into its recent past. The study is published in Scientific Reports.

Quantum physicists from MIPT decided to check if time could spontaneously reverse itself at least for an individual particle and for a tiny fraction of a second. That is, instead of colliding billiard balls, they examined a solitary electron in empty interstellar space. "Suppose the electron is localized when we begin observing it. This means that we're pretty sure about its position in space. The laws of quantum mechanics prevent us from knowing it with absolute precision, but we can outline a small region where the electron is localized," says study co-author Andrey Lebedev from MIPT and ETH Zurich. The physicist explains that the evolution of the electron state is governed by Schrodinger's equation. Although it makes no distinction between the future and the past, the region of space containing the electron will spread out very quickly. That is, the system tends to become more chaotic. The uncertainty of the electron's position is growing. This is analogous to the increasing disorder in a large-scale system -- such as a billiard table -- due to the second law of thermodynamics.

"However, Schrodinger's equation is reversible," adds Valerii Vinokur, a co-author of the paper, from the Argonne National Laboratory, U.S. "Mathematically, it means that under a certain transformation called complex conjugation, the equation will describe a 'smeared' electron localizing back into a small region of space over the same time period." Although this phenomenon is not observed in nature, it could theoretically happen due to a random fluctuation in the cosmic microwave background permeating the universe. The team set out to calculate the probability to observe an electron "smeared out" over a fraction of a second spontaneously localizing into its recent past. It turned out that even across the entire lifetime of the universe -- 13.7 billion years -- observing 10 billion freshly localized electrons every second, the reverse evolution of the particle's state would only happen once. And even then, the electron would travel no more than a mere one ten-billionth of a second into the past. The researchers then attempted to reverse time in a four-stage experiment by observing the state of a quantum computer made of superconducting qubits, instead of an electron. The researchers "found that in 85 percent of the cases, the two-qubit quantum computer returned back into the initial state," reports Phys.Org. "When three qubits were involved, more errors happened, resulting in a roughly 50 percent success rate. According to the authors, these errors are due to imperfections in the actual quantum computer. As more sophisticated devices are designed, the error rate is expected to drop."

President Trump announced an emergency order from the Federal Aviation Administration on Wednesday grounding Boeing 737 Max jets in the wake of an Ethiopian Airlines crash Sunday and a Lion Air accident in October that together killed 346 people. The emergency order comes two days after the FAA said the Boeing 737 Max planes are still airworthy. NBC News reports: Trump's announcement came as the FAA faced mounting pressure from aviation advocates and others to ban flights of the planes pending the completion of investigations into the deadly accidents. Sunday's crash killed 157 people and the one in Indonesia in October left 189 dead. "We're going to be issuing an emergency order of prohibition to ground all flights of the 737 Max 8 and the 737 Max 9 and planes associated with that line," Trump announced, referring to "new information and physical evidence that we've received" in addition to some complaints.

The FAA said it decided to ground the jets after it found that the Ethiopian Airlines aircraft that crashed had a flight pattern very similar to the Lion Air flight. "It became clear that the track of the Ethiopian flight behaved very similarly to the Lion Air flight," said Steven Gottlieb, deputy director of accident investigations for the FAA. United States airports and airlines reacted to the order Wednesday, acknowledging that it will lead to canceled flights. American has roughly 85 flights a day on the Boeing Max 8 and Max 9 jets. United Airlines has about 40 such flights. Southwest Airlines has the most, about 150 flights per day on these types of jets out of the airline's total of about 4,100 flights daily.

Amazon lobbied more government entities last year than any other public U.S. company, covering issues like healthcare, transportation, defense, and labor regulation. "Across 2018, Amazon contacted 40 different federal entities on 21 different general issue areas," reports Fortune, citing a report from Axios. "The only tech giant to lobby on more issues than Amazon was Google's Alphabet." From the report: In terms of money spent, Amazon's $14.4 million is topped only by Alphabet's $21 million, says Bloomberg. While the tech industry overall spent less than half of the $280 million from pharmaceutical and healthcare products companies in Washington, Amazon has increased spending 460% since 2012, growing quickly within its trade. According to Axios, Amazon lobbied on self-driving car and drone issues, hinting at new methods of delivery. It supported a law allowing pharmacists to tell patients when using their insurance is actually more expensive, aiding Amazon's new investment in PillPack. It also covered the labeling of bioengineered food and a pilot program allowing online shoppers to use the Supplemental Nutritional Assistance Program -- signs of Amazon's emerging grocery business.

Valve has announced the "early beta" release of Steam Link Anywhere, which will enable streamed gaming to any compatible device, and Steam Networking Sockets APIs, granting developers access to the technology and infrastructure that underlies CS:GO and Dota 2. PC Gamer reports: Steam Link Anywhere is an extension of Steam Link that will enable users to connect to their PCs and play games from anywhere (thus the name), rather than being limited to a local network. It's compatible with both the Steam Link hardware and app, and will be rolled out automatically (and freely) to everyone who owns the hardware with beta firmware installed, the Android app beta, or the Raspberry Pi app. You'll also need to be enrolled in the Steam client beta, and have the latest version installed. Assuming you've got all that covered, you'll see an "Other Computer" option on the screen when searching for computers to connect to via Steam Link. Select that, follow the instructions, and you'll be set. Valve didn't provide specific network requirements but said you'll need "a high upload speed from your computer and strong network connection to your Steam Link device" in order to use it.

Steam Networking Sockets APIs isn't as flashy (and that "flash" is definitely relative) but is aimed squarely at developers, and could be even more significant to Steam's fortunes given the pressure it's facing from the Epic Games Store: It enables developers to run their game traffic through Valve's own private gaming network, providing players "faster and more secure connections." It's free for developers, and "a large portion" of the API is now open source, which could be a pretty big draw for devs look to incorporate online play with a minimum of fuss. If that's your bag, you can get more detailed information at steamcommunity.com, and Valve will be talking about the new feature in-depth at a Game Developer's Conference panel next Thursday, March 21.
