China's fleet of electric buses appear to be denting oil demand more than electric cars. "By the end of this year, a cumulative 270,000 barrels a day of diesel demand will have been displaced by electric buses, most of it in China," reports Bloomberg, citing a new report published by BloombergNEF. "That's more than three times the displacement by all the world's passenger electric vehicles (a market where Tesla has a share of about 12 percent)." From the report: Despite rapid growth, the impact on the oil market from electric vehicles remains relatively small. Collectively, buses and electric vehicles account for about 3 percent of oil demand growth since 2011, and 0.3 percent of current global consumption, according to BloombergNEF figures and data from the International Energy Agency. Buses matter more because of their size and constant use. For every 1,000 electric buses on the road, 500 barrels of diesel are displaced each day, BloombergNEF estimates. By comparison, 1,000 battery electric vehicles remove just 15 barrels of oil demand.

Still, the EV market's impact on oil consumption is only going to grow. By 2040, electric vehicles could displace much as 6.4 million barrels a day of demand, while fuel efficiency improvements will erase another 7.5 million barrels a day, according to BloombergNEF's May 2018 long-term EV outlook.

Oculus VR unveiled the Oculus Rift S, a higher-resolution pair of virtual reality goggles that remove the need for external cameras by incorporating built-in tracking. The company partnered with Lenovo "to help it speed up manufacturing and to improve upon the design of the original Rift," reports The Verge. From the report: The result is a new VR device that is more comfortable, sports 2560 x 1440 resolution (or 1280 x 1440 per eye), and features the same inside-out tracking system that will ship on Oculus' upcoming standalone Quest headset, which the company calls Oculus Insight. That way, you won't need cumbersome cameras to enable full-body movement. In another twist, both the Quest and Rift S device will cost exactly the same at launch: $399, with the same pair of slightly modified Touch motion controllers included and the same integrated audio system (plus a headphone jack for external audio). That decision makes it clear that Oculus wants its VR platform to offer a choice not between two vastly different pieces of hardware, but by the more simple determination of whether you have the hardware to power PC-grade VR. The Rift S will support every existing and future game on the Rift platform. "The company is also enabling cross-buy and cross-play features," the report adds. "That way, you can buy a Quest and, at a later date, upgrade to a Rift S and still have your entire library intact. Additionally, multiplayer games that support both platforms will let players play one another, regardless of whether you're playing on a Quest or Rift device."

The Rift S and Quest will be shipping this spring.

A recent experiment by Josh Frantz, a senior security consultant at Rapid7, suggests that users are taking few if any steps to protect their private information before releasing their used devices back out into the wild. From a report: For around six months, he collected used desktop, hard disks, cellphones and more from pawn shops near his home in Wisconsin. It turned out they contain a wealth of private data belonging to their former owners, including a ton of personally identifiable information (PII) -- the bread and butter of identity theft. Frantz amassed a respectable stockpile of refurbished, donated, and used hardware: 41 desktops and laptops, 27 pieces of removable media (memory cards and flash drives), 11 hard disks, and six cellphones. The total cost of the experiment was a lot less than you'd imagine. "I visited a total of 31 businesses and bought whatever I could get my hands on for a grand total of around $600," he said.

Frantz used a Python-based optical character recognition (OCR) tool to scan for Social Security numbers, dates of birth, credit card information, and other sensitive data. And the result was, as you might expect, not good. The pile of junk turned out to contain 41 Social Security numbers, 50 dates of birth, 611 email accounts, 19 credit card numbers, two passport numbers, and six driver's license numbers. Additionally, more than 200,000 images were contained on the devices and over 3,400 documents. He also extracted nearly 150,000 emails.

schwit1 shares a report from ScienceAlert: Researchers at the University of Southern Carolina (USC) claim to have created the first AI-controlled robotic limb that can learn how to walk without being explicitly programmed to do so. The algorithm they used is inspired by real-life biology. Just like animals that can walk soon after birth, this robot can figure out how to use its animal-like tendons after only five minutes of unstructured play.

Today, most robots take months or years before they are ready to interact with the rest of the world. But with this new algorithm, the team has figured out how to make robots that can learn by simply doing. This is known in robotics as "motor babbling" because it closely mimics how babies learn to speak through trial and error. "During the babbling phase, the system will send random commands to motors and sense the joint angles," co-author Ali Marjaninejad an engineer at USC, told PC Mag. "Then, it will train the three-layer neural network to guess what commands will produce a given movement. We then start performing the task and reinforce good behavior."

dryriver writes: Crytek has published a video showing an ordinary AMD Vega 56 GPU -- which has no raytracing specific circuitry and only costs around $450 -- real-time ray tracing a complex 3D city environment at 4K 30 FPS. Crytek says that the technology demo runs fine on most normal NVIDIA and AMD gaming GPUs. As if this wasn't impressive already, the software real-time ray tracing technology is still in development and not even final. The framerates achieved may thus go up further, raising the question of precisely what the benefits of owning a super-expensive NVIDIA RTX 20xx series GPU are. Nvidia has claimed over and over again that without its amazing new RTX cores and AI denoiser, GPUs will choke on real-time ray tracing tasks in games. Crytek appears to have proven already that with some intelligently written code, bog ordinary GPU cores can handle real-time ray tracing just fine -- no RTX cores, AI denoiser or anything else NVIDIA touts as necessary.

In January 2019, iFixit revealed a design flaw where the ribbon cable that connects the body of some MacBook Pros to their display wears down too quickly, causing uneven backlighting at the bottom of the display. There now appears to be growing frustration among users at Apple's reaction. Vlad Savov from The Verge said it is time for the company to acknowledge and deal with the issue: A petition, now numbering more than 15,000, would beg to differ. It calls for Apple to publicly recognize Flexgate as a design flaw, and to commit to repair all MacBook Pro laptops affected by it. I think that's exactly what Apple should do, and it's no less than we should expect from a company that touts its reliability and user satisfaction numbers any chance it gets. No one should have to pay upwards of $500 to replace an entire display just because Apple (a) decided to affix a fragile cable to one of the most expensive components in its MacBook Pro, and (b) miscalculated the necessary length of that cable in its first design.

Today, Apple will finally begin taking orders for newly refreshed 21- and 27-inch iMacs. The new versions don't change the basic design or add major new features, but they offer substantially faster configuration options for the CPU and GPU. From a report: The 21.5-inch iMac now has a 6-core, eighth-generation Intel CPU option -- up from a maximum of four cores before. The 27-inch now has six cores as the standard configuration, with an optional upgrade to a 3.6GHz, 9th-gen, 8-core Intel Core i9 CPU that Apple claims will double performance over the previous 27-inch iMac. The base 27-inch model has a 3GHz 6-core Intel Core i5 CPU, with intermediate configurations at 3.1GHz and 3.7GHz (both Core i5). The big news is arguably that both sizes now offer high-end, workstation-class Vega-graphics options for the first time. Apple added a similar upgrade option to the 15-inch MacBook Pro late last year. In this case, the 21.6-inch iMac has an option for the 20-compute-unit version of Vega with 4GB of HBM2 video memory. That's the same as the top-end 15-inch MacBook Pro option.

The 27-inch iMac can now be configured with the Radeon Pro Vega 48 with 8GB of HBM2. For reference, the much pricier iMac Pro has Vega 56 and Vega 64 options. Apple claims the Vega 48 will net a 50-percent performance improvement over the Radeon Pro 580, the previous top configuration. Speaking of the previous top configuration, the non-Vega GPU options are the same as what was available yesterday. The only difference is that they now have an "X" affixed to the numbers in their names, per AMD branding conventions -- i.e., Radeon Pro 580X instead of 580. RAM options are the same in terms of volume (up to 32GB for the 21.5-inch and 64GB for the 27-inch), but the DDR4 RAM is slightly faster now, at 2666MHz.

Sophisticated AI generally isn't an option for homebrew devices when the mini computers can rarely handle much more than the basics. NVIDIA thinks it can do better -- it's unveiling an entry-level AI computer, the Jetson Nano, that's aimed at "developers, makers and enthusiasts." From a report: NVIDIA claims that the Nano's 128-core Maxwell-based GPU and quad-core ARM A57 processor can deliver 472 gigaflops of processing power for neural networks, high-res sensors and other robotics features while still consuming a miserly 5W. On the surface, at least, it could hit the sweet spot if you're looking to build your own robot or smart speaker. The kit can run Linux out of the box, and supports a raft of AI frameworks (including, of course, NVIDIA's own). It comes equipped with 4GB of RAM, gigabit Ethernet and the I/O you'd need for cameras and other attachments.

An anonymous reader quotes a report from The New York Times: The Department of Energy disclosed details on Monday of one of the most expensive computers being built: a $500 million machine based on Intel and Cray technology that may become crucial in a high-stakes technology race between the United States and China (Warning: source may be paywalled; alternative source). The supercomputer, called Aurora, is a retooling of a development effort first announced in 2015 and is scheduled to be delivered to the Argonne National Laboratory near Chicago in 2021. Lab officials predict it will be the first American machine to reach a milestone called "exascale" performance, surpassing a quintillion calculations per second. That's roughly seven times the speed rating of the most powerful system built to date, or 1,000 times faster than the first "petascale" systems that began arriving in 2008. Backers hope the new machines will let researchers create significantly more accurate simulations of phenomena such as drug responses, climate changes, the inner workings of combustion engines and solar panels.

Aurora, which far exceeds the $200 million price for Summit, represents a record government contract for Intel and a test of its continued leadership in supercomputers. The Silicon Valley giant's popular processors -- the calculating engine for nearly all personal computers and server systems -- power most such machines. But additional accelerator chips are considered essential to reach the very highest speeds, and its rival Nvidia has built a sizable business adapting chips first used with video games for use in supercomputers. The version of Aurora announced in 2015 was based on an Intel accelerator chip that the company later discontinued. A revised plan to seek more ambitious performance targets was announced two years later. Features discussed on Monday include unreleased Intel accelerator chips, a version of its standard Xeon processor, new memory and communications technology and a design that packages chips on top of each other to save space and power.

Ahead of a planned event next week, Apple today unveiled two new iPads. From a report: The new, larger, 10.5-inch iPad Air will arrive with a 70 percent performance boost compared to its predecessor, thanks to the company's A12 Bionic chip with Apple's Neural Engine. That'll be useful alongside the now 20-percent larger display -- which is compatible with the first-gen Apple Pencil too.

A new iPad Mini has been a long time coming. The 7.9-inch option will, barring screen size, match the Air on specs. The screen is also 25 percent brighter versus old iPad minis, and will also support Apple Pencil -- the tiniest model to do so. Both new iPads have a laminated display that brings the surface glass and screen closer together to improve visibility -- and making them at least a little more desirable than Apple's entry-level iPad. Neither has FaceID built-in, it seems. Look, there's that Home button. The new iPad mini starts at $399 for the Wi-Fi model and $529 for the variant that includes cellular support. The new iPad Air starts at $499 for Wi-Fi, and $629 for Wi-Fi and cellular model.

Munky101 tipped us off to some interesting comments from New York's activist congresswoman Alexandria Ocasio-Cortez. TechCrunch reports: It's impossible to discuss the seismic shift toward automation without a conversation about job loss. Opponents of these technologies criticize a displacement that could someday result in wide-scale unemployment among what is often considered "unskilled" roles. Advocates, meanwhile, tend to suggest that reports of that nature tend to be overstated. Workforces shift, as they have done for time immemorial. During a conversation at SXSW this week, New York congresswoman Alexandria Ocasio-Cortez offered another take entirely.

"We should not be haunted by the specter of being automated out of work," she said in an answer reported by The Verge. "We should be excited by that. But the reason we're not excited by it is because we live in a society where if you don't have a job, you are left to die. And that is, at its core, our problem... We should be excited about automation, because what it could potentially mean is more time educating ourselves, more time creating art, more time investing in and investigating the sciences, more time focused on invention, more time going to space, more time enjoying the world that we live in," The Verge quoted Ocasio-Cortez as saying. "Because not all creativity needs to be bonded by wage."

And Ocasio-Cortez cited Bill Gates' suggestion (first floated in a presentation on Quartz) that a robot tax might be a way to make that vision real. "What [Gates is] really talking about is taxing corporations," she reportedly said. "But it's easier to say: 'tax a robot.' "
Science fiction writer William Gibson called her comments "shockingly intelligent" for a politician. Fast Company adds that robots "have put half a million people out of work in the United States, and researchers estimate that bots could take 800 million jobs by 2030" -- then quotes Ocasio-Cortez's assessment of the unfair state of labor today.

"We should be working the least amount we've ever worked, if we were actually paid based on how much wealth we were producing, but we're not," she said. "We're paid by how little we're desperate enough to accept. And then the rest is skimmed off and given to a billionaire."

An anonymous reader quotes PC Gamer: Not too long into a 168-hour VR marathon session, Jak Wilmot admits the monotony got to him. Wilmot, who is the co-founder of Disrupt VR, also says this experiment is "quite possibly the dumbest thing" he's ever done. So, why do it? For science, of course. I can't imagine immersing myself in a virtual world for a full week, nonstop night and day. Wilmot did it, though, for the most part -- he allowed himself 30 seconds to switch VR headsets when needed, and 30 seconds without a headset on to eat, if required. Other than those small breaks, he spent every other moment in VR...

There doesn't seem to be some big takeaway from this experiment (aside from, perhaps, don't drink coffee while playing VR), though one thing I also found interesting was his integration back into the real world when the experiment was over. "I have never appreciated the smell of outside air so much. One thing we cannot replicate is nature. We can do it visually and auditorally, but there is something about the energy of outside that is amazing," Wilmot observed.
PC Gamer calls it "probably at least partially a publicity stunt. But it's still interesting to see how donning a VR headset for an extended period of time and essentially living in virtual worlds can mess with the mind." Wilmot wore VR gear while working -- and even while showering (with the VR gear protected by plastic), blacking out his windows so he couldn't tell day from night, calling it "a week in the future..."

"I almost feel like I'm in my own 500-suare-foot spaceship," he says at one point, "and I'm really missing earth, and I'm missing nature." Early on he also reported some mild claustrophobia.

You can watch the moment where after seven days he removes the headset and returns to conventional reality, joking "Oh my gosh, the graphics are so good." He reports a slight disorientation as his eyes catch up with real ilfe, and says it changed his perspective on people in the real world, seeing them as "individuals in one collection, one environment -- as avatars."

schwit1 shares a report from IEEE Spectrum: A team at Katholieke Universiteit Leuven, or KU Leuven, says it has developed a solar panel that converts sunlight directly into hydrogen using moisture in the air. The prototype takes the water vapor and splits it into hydrogen and oxygen molecules. If it scales successfully, the technology could help address a major challenge facing the hydrogen economy. A small but growing number of facilities are producing "green" hydrogen using electrolysis, which splits water molecules using electricity -- ideally from renewable sources such as wind and solar. Other researchers, including the team in Belgium, are developing what's called direct solar water-splitting technologies. These use chemical and biological components to split water directly on the solar panel, forgoing the need for large, expensive electrolysis plants.

KU Leuven sits on a grassy campus in Flanders, the Dutch-speaking northern region of Belgium. Earlier this month, professor Johan Martens and his team at the Center for Surface Chemistry and Catalysis announced their prototype could produce 250 liters of hydrogen per day on average over a full year, which they claim is a world record. A family living in a well-insulated Belgian house could use about 20 of these panels to meet their power and heating needs during an entire year, they predict. The solar panel measures 1.65 meters long -- roughly the height of a kitchen refrigerator, or this reporter -- and has a rated power output of about 210 watts. The system can convert 15 percent of the solar energy it receives into hydrogen, the team says. That's a significant leap from 0.1 percent efficiency they first achieved 10 years ago.

An anonymous reader quotes a report from Phys.Org: Coal is the primary fuel source for Midwest electric utilities. Michigan Technological University researchers found that increasing renewable and distributed generation energy sources can save Michigan electric consumers money. As renewable energy technologies and access to distributed generation like residential solar panels improve, consumer costs for electricity decrease. Making electricity for yourself with solar has become more affordable than traditional electricity fuel sources like coal. However, as three Michigan Tech researchers contend in a new study, while utility fuel mixes are slowly shifting away from fossil fuels toward renewable sources, Michigan utilities, and U.S. utilities broadly, continue a relationship with fossil fuels that is detrimental to their customers.

In the paper, Prehoda and co-authors Joshua M. Pearce, Richard Witte Endowed Professor of Materials Science and Engineering, and Chelsea Schelly, associate professor of sociology, note that in the U.S., "70 percent of coal plants run at a higher cost than new renewable energy and by 2030 all of them will." The researchers provide a breakdown of savings per kilowatt hour by county that Michigan residents could achieve if they produce their own electricity with solar photovoltaic panels. The most significant impacts of distributed generation with solar are in the Upper Peninsula, where residential customers could see savings of approximately 7 cents per kilowatt hour. Assuming the average residential consumer uses 600 kilowatt hours of electricity monthly, this is a savings of $42 per utility bill. Downstate, the average savings per utility bill under the researchers' model is approximately $30 monthly. However, not all Michigan consumers can take advantage of the opportunity to self-generate, as some utilities are blocking additional net-metered distributed generation in their areas. The study has been published in the journal Energies.

Last night, Tesla CEO Elon Musk unveiled the company's brand new electric SUV, the Model Y. The car is only slightly larger than the Model 3 and shares 75% of its parts, leaving many people wanting more. But, as USA Today reports, "The ho-hum reaction to Tesla's new electric SUV is, oddly enough, exactly what the company needs. [F]or a company that needs a little less pizzazz and a little more substance to make good on its promise to become a sustainable force in the auto industry, the Model Y hit the right marks." From the report: It's essentially a crossover version of the Tesla Model 3 compact car, bearing the design hallmarks of a hatchback and sharing the same architectural platform as its car sibling. That Tesla devotees weren't rewarded with sizzling new features on the Model Y illustrates that the company is getting serious about selling vehicles. After all, a compact SUV is precisely what Americans want: a driveable vehicle that puts safety first and flash second. Versions with five and seven seats will be available, with starting prices ranging from $39,000 for the base version to $60,000 for a performance model. If Musk had tried to break new technological barriers or adopt outlandish styling on the Model Y, he would have risked making the vehicle too difficult to manufacture and unappealing to conventional SUV buyers.

The first-available model will start at $47,000 and arrive in fall 2020. You can place a refundable deposit of $2,500 to secure your place in line when the vehicle becomes available. The base model of the Model Y -- the $39,000 version -- won't be available until "sometime in 2021," Musk said. Families can make the Model Y their primary vehicle since the battery range goes from 230 miles to 300 miles depending on the version. That stacks up well against other EVs on the market, such as the Chevrolet Bolt's 238 and the Hyundai Kona's 258. And while techies might not find the Model Y exhilarating, it will come equipped with software and sensors capable of autonomous driving, whenever it becomes legal. But buyers will have to pay for the system upgrade of $3,000 to $5,000.
