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.

An anonymous reader quotes a report from The Daily Beast: First Look Media announced Wednesday that it was shutting down access to whistleblower Edward Snowden's massive trove of leaked National Security Agency documents. Over the past several years, The Intercept, which is owned by First Look Media, has maintained a research team to handle the large number of documents provided by Snowden to Intercept journalists Laura Poitras and Glenn Greenwald. But in an email to staff Wednesday evening, First Look CEO Michael Bloom said that as other major news outlets had "ceased reporting on it years ago," The Intercept had decided to "focus on other editorial priorities" after expending five years combing through the archive. "The Intercept is proud of its reporting on the Snowden archive, and we are thankful to Laura Poitras and Glenn Greenwald for making it available to us," Bloom wrote. He added: "It is our hope that Glenn and Laura are able to find a new partner -- such as an academic institution or research facility -- that will continue to report on and publish the documents in the archive consistent with the public interest." Poitras reprimanded First Look Media for its decision to shut down its archives, and lay off 4 percent of its staff who had maintained them. "This decision and the way it was handled would be a disservice to our source, the risks we've all taken, and most importantly, to the public for whom Edward Snowden blew the whistle," she wrote.

"Late Thursday evening, Greenwald tweeted that both he and Poitras had full copies of the archives, and had been searching for a partner to continue research," reports The Daily Beast.

An anonymous reader shares a report: Robotic hands have a tough time getting a grip on pliable objects, but it's not for lack of trying -- most make do with rigid pincers that aren't designed for precision grasping. Fortunately, if a newly published paper is any indication, more versatile systems are on the horizon. In it, researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Harvard describe a novel gripper design that's capable of lifting items in a range of weights, shapes, and sizes.

The team's hollow, cone-shaped gripper comprises three parts -- a 3D-printed, 16-piece silicone rubber skeleton with a gripper-to-mount connector encased by an airtight skin -- that together collapse in on objects as opposed to clutching them. It was inspired by the "magic ball," an origami design that's folded from a rectangular piece of paper pre-creased with a repeating, offset pattern that reversibly changes between a spherical and cylindrical shape. The gripper is powered by a pneumatic vacuum and covered by either a 27-inch latex rubber balloon or a TPU-coated nylon fabric sheet, depending on the configuration. The researchers tested three: one with a self-folded fabric skin skeleton, a second with a rubber-molded skeleton, and a third with a tougher rubber skeleton.

[...] In one experiment where the team mounted the gripper on a robot to test its strength, it managed to lift and grasp objects -- 12 food items, 19 different bottles and cups, and 14 miscellaneous items, some weighing over four pounds -- that were 70 percent of its diameter and up to 120 times its weight without damaging them. It currently works best with cylindrical objects like bottles and cans, according to Shuguang Li, a joint postdoctoral student at MIT CSAIL and Harvard's John A. Paulson School of Engineering and Applied Sciences (SEAS), which makes it a natural fit for factory production lines.

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.

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.

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.

New Mexico's state House of Representatives passed the "Energy Transition Act" on Tuesday, where it's expected to be signed quickly by Governor Michelle Lujan Grisham. The bill "commits the state to getting 100 percent of its energy from carbon-free sources by 2045," reports Ars Technica. From the report: The bill includes interim goals mandating that 50 percent of the state's energy mix be renewable by 2030 and 80 percent of the energy mix be renewable by 2040. The state currently buys no nuclear power, which is not renewable but qualifies as a zero-carbon energy source. The bill passed yesterday does not require that 100 percent of the state's energy be renewable by 2045; it just specifies that no electricity come from a carbon-emitting source.

New Mexico is unique among these states because it is a relatively coal-heavy state, generating 1.5 gigawatts of coal-fired electricity as of November 2018. Last month, the state's Public Service Company of New Mexico had slated its 847MW San Juan coal plant for shut down by 2022, but a New York hedge fund called Acme Equities swooped in with an offer to buy the 46-year-old plant. According to Power Magazine, Acme intends to retrofit the plant with carbon capture and sequestration technology. If the deal goes through, Acme would use the captured carbon in enhanced oil recovery, where carbon is forced into older or weak oil wells to improve the pressure of the well and extract more oil. But with the passage of this bill, Acme's offer may not stand. New Mexico In Depth writes that the bill puts "$30 million toward the clean-up of the [San Juan] coal-fired power plant and the mine that supplies it and $40 million toward economic diversification efforts in that corner of the state and support for affected power plant employees and miners."

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.

Researchers at Google, the University of Massachusetts at Amherst, and the University of California Santa Barbara has solved one of the biggest limitations with quantum computing: all the control and readout circuits of quantum computer systems must be at room temperature, while their superconducting qubits live in a cryogenic enclosure at less than 1 kelvin. "For today's sub-100-qubit systems, there's enough space for specialized RF cabling to come in and out of the enclosure," reports IEEE Spectrum. "But to scale up to the million-qubit systems needed to do really cool stuff, there just won't be enough room."

At the IEEE International Solid-State Circuits Conference in San Francisco last month, the researchers reported making a key control circuit in CMOS that will work at cryogenic temperatures. They described it as "a high-performance, low-power pulse modulator needed to program the qubits." From the report: "The current approach is OK for now," says Joseph Bardin, a University of Massachusetts at Amherst associate professor of electrical and computer engineering who designed the IC while on sabbatical at Google. "But it's not scalable to a million qubits." For Google's 72-qubit quantum processor there are already 168 coaxial cables going into the refrigerator and connecting to the 10-millikelvin quantum processor. The pulse modulator IC Bardin worked on is used to encode quantum states on a qubit in order to execute a program. Quantum computers get their parallelizing power because qubits don't have to be just 0 or 1, like the bits in an ordinary computer. Instead, they can be a mix of those states. The pulse modulator uses a specific set of RF frequencies to produce that mix.

"The biggest challenge is heat dissipation," explains Bardin. The qubits are at 10 millikelvins, but the control circuits, which necessarily throw off heat, can't be held that low. The researchers aimed for 4 K for the control IC. "However, at 4 K, thermodynamics limits the efficiency of cooling. The best you're going to get is about 1 percent efficiency. In practice it's worse." So the power dissipated by the electronics per qubit had to be only in the milliwatt range. That power constraint had to be balanced with the need for control accuracy, Bardin says. This was complicated by how differently CMOS transistors behave at 4 k, which is a more than 200 degrees below what silicon foundries' simulation models can deal with. Bardin and the Google team managed to design the IC in a way that compensates for these problems and achieves the balance between power consumption and performance. The resulting IC consumed less than 2 mW, yet it was able to put a qubit through its paces in testing.

An anonymous reader quotes a report from Ars Technica: A report from Business Insider claims that Google has axed "dozens" of employees from its laptop and tablet division. BI's sources describe the move as "roadmap cutbacks" and also say that Google will likely "pare down the portfolio" in the future. Google's Hardware division is run by Rick Osterloh and is expected to launch a game streaming console later this month. The division is responsible for the Pixel phones, Google Home speakers, the Chromecast, Google Wi-Fi, and lately, the Nest smart home division.

You could also call the "laptop and tablet" division the "Chrome OS" division. Both the Pixelbook and Pixel Slate ran Chrome OS, and they are the company's only products supporting that operating system. Is Chrome OS going to be OK? BI notes that manufacturing roles in the hardware division haven't changed, so in the short-term, Google's product lineup is likely to keep going. The report says that Google had "a bunch of stuff in the works" that now probably won't see the light of day. The move comes after the group received pressure to turn Google Hardware into "a real business" from higher-ups at Google/Alphabet. It's easy to imagine that the laptops and tablets -- which are Google Hardware's most expensive products -- were selling the worst.

An anonymous reader quotes a report from VentureBeat: Google today launched Chrome 73 for Windows, Mac, and Linux. The release includes support for hardware media keys, PWAs and dark mode on Mac, and the usual slew of developer features. You can update to the latest version now using Chrome's built-in updater or download it directly from google.com/chrome. Chrome 73 supports Progressive Web Apps (PWAs) on macOS. These apps install and behave like native apps (they don't show the address bar or tabs). Google killed off Chrome apps last year and has been focusing on PWAs ever since. Adding Mac support means Chrome now supports PWAs on all desktop and mobile platforms: Windows, Mac, Linux, Chrome OS, Android, and iOS. Chrome now also supports dark mode on Apple's macOS; dark mode for Windows is on the way, the team promises.

The VentureBeat report includes a long list of developer features included in this release, as well as all the security fixes found by external researchers. Chrome 73 implements a total of 60 security fixes.

Shortages of Intel's CPUs are expected to worsen in the second quarter compared to the first as demand for Chromebooks, which are mostly equipped with Intel's entry-level processors, enters the high period, according to Digitimes Research. From the report: Digitimes Research expects Intel CPUs' supply gap to shrink to 2-3% in the first quarter with Core i3 taking over Core i5 as the series hit hardest by shortages. The shortages started in August 2018 with major brands including Hewlett-Packard (HP), Dell and Lenovo all experiencing supply gaps of over 5% at their worst moment. Although most market watchers originally believed that the shortages would gradually ease after vendors completed their inventory preparations for the year-end holidays, the supply gap in the fourth quarter of 2018 still stayed at the same level as that in the third as HP launched a second wave of CPU inventory buildup during the last quarter of the year, prompting other vendors to follow suit. Taiwan-based vendors were underprepared and saw their supply gaps expand from a single digit percentage previously to over 10% in the fourth quarter. With all the impacts, the notebook market continued suffering a 4-5% supply gap in the fourth quarter of 2018.

In 2017, Mozilla experimented with a service that let you transfer 1GB files by sharing a web address with the recipient. Firefox Send is now out of testing and boasts a magnified 2.5GB file-size limit if you log into your Firefox account. From a report: Firefox Send is handy for those moments when you need to share video, audio or photo files that can be too big to squeeze into an email attachment. [...] Firefox Send, which will also be available as an Android app, illustrates one of Mozilla's efforts to diversify beyond the Firefox browser. Mozilla touts Firefox Send as focusing on privacy and uses encryption to protect files. Firefox Send files are available for up to seven days and can be password-protected. You can also limit the number of times they're downloaded.
