Valve has delayed the release of its Steam Deck handheld by several months, it announced in a statement today. The anticipated handheld will now start rolling out in February 2022, pushed back from an initial December release. Kotaku reports: "We're sorry about this -- we did our best to work around the global supply chain issues, but due to material shortages, components aren't reaching our manufacturing facilities in time for us to meet our initial launch dates," Valve wrote. "Based on our updated build estimates, Steam Deck will start shipping to customers February 2022. This will be the new start date of the reservation queue -- all reservation holders keep their place in line but dates will shift back accordingly."

Apple says it will back off its plan to break Face ID on independently repaired iPhones. Ars Technica reports: The company's often contentious relationship with the repair community was tested again when "unauthorized" iPhone 13 screen replacements started resulting in broken Face ID systems. A new report from The Verge says that Apple "will release a software update that doesn't require you to transfer the microcontroller to keep Face ID working after a screen swap." Screen replacements are the most common smartphone repairs. Apple included a new microcontroller in the iPhone 13's display that pairs each screen with other components in the phone. As iFixit reported, if a third-party repair shop replaced the iPhone 13 display, Apple would disable the phone's Face ID system. [...] After a wave of bad press, it's "crisis averted" for the repair community. It would be nice if this was never an issue in the first place, though.

An anonymous reader quotes a report from Motherboard: Just outside of Shiprock, New Mexico, on land belonging to the Navajo Nation, a Bitcoin mine owned and operated by a Canadian investment company consumes seven megawatts of power each month -- enough to power 19,600 homes. The operation is run by a firm called WestBlock Capital and mines between 23 and 25 bitcoins per month, equivalent to roughly $1.4 to $1.6 million USD, with a majority of its power coming from renewable solar energy. According to a press release from the mine's parent company, Luxxfolio, the mine accesses these resources "at significantly reduced cost in the bottom decile of global power costs."

But all around the mine, Dine -- citizens of the Navajo Nation -- live without electricity or running water in their homes. The Navajo Tribal Utility Authority (NTUA), the nation's non-profit utility enterprise that initially partnered with Calgary, Alberta blockchain company WestBlock on the mine project, is working to connect more homes on the nation to basic utilities. A short documentary detailing the project by Bitcoin mining hosting company Compass was released last week, framing the mine as a means to achieve sovereignty and economic prosperity for the nation. But some Dine are bristling at the idea of a foreign Bitcoin mining company getting access to dirt cheap electricity while residents in Navajo Nation live without basic utilities like power and running water.

Tyler Puente, who commented on a since-deleted Facebook post from Navajo Nation President Jonathan Nez's Facebook page about the mine's groundbreaking ceremony that Navajo leadership are allowing outsiders to take advantage of Dine, told Motherboard that he sees the Bitcoin mine as a form of "financial colonialism." "I think Bitcoin companies prey on communities like my own," said Puente. "My perspective is that we're being used." To some Dine, WestBlock project resembles a form of crypto-colonialism, a term that describes the exploitation of lands and resources by cryptocurrency and blockchain interests, often under the guise of progressive or egalitarian rhetorics for the host communities.

PolygamousRanchKid shares a report from the BBC: Rolls-Royce has been backed by a consortium of private investors and the UK government to develop small nuclear reactors to generate cleaner energy. The creation of the Rolls-Royce Small Modular Reactor (SMR) business was announced following a [195 million pound] cash injection from private firms and a [210 million pound] grant from the government. It is hoped the new company could create up to 40,000 jobs by 2050. However, critics say the focus should be on renewable power, not new nuclear.

Rolls-Royce SMR said one of its power stations would occupy about one tenth of the size of a conventional nuclear plant -- the equivalent footprint of two football pitches -- and power approximately one million homes. The firm said a plant would have the capacity to generate 470MW of power, which it added would be the same produced by more than 150 onshore wind turbines. Warren East, Rolls-Royce chief executive, said the company's SMR technology offered a "clean energy solution" which help tackle climate change.

However, Paul Dorfman, chairman of the Nuclear Consulting Group think tank, told the BBC's Today program there was danger that the money spent on nuclear power would hit funding for other power sources. "If nuclear eats all the pies which it is looking to be doing we won't have enough money to do the kind of things we need to do which we know practically and technologically we can do now," he said. Greenpeace's chief scientist Dr Doug Parr said SMRs were still more expensive than renewable technologies and added there was "still no solution to dispose of the radioactive waste they leave behind and no consensus on where they should be located." "What's worse, there's not even a prototype in prospect anytime soon," he added. "The immediate deadline for action is sharp cuts in emissions by 2030, and small reactors will have no role in that."

An anonymous reader quotes a report from Ars Technica: Disney+'s next major app update, coming to all devices later this week, continues the service's latest efforts to please nitpicky A/V obsessors with a new screen ratio format meant to fill more of your HDTV screen in a way that filmmakers originally intended. "IMAX Digital" is coming to all devices that support Disney+ starting this Friday as part of the service's "Disney+ Day" promotion. This "17.1:9" format will land exclusively on 13 Marvel Studios films to start, and the move coincides with the streaming premiere of Shang-Chi and the Legend of the Ten Rings -- a film that skipped Disney's experiment with simultaneous launches in theaters and on Disney+ earlier this year. When a film switches to an IMAX Digital ratio, the usual black bars that signify a wider-screen 21:9 ratio will be reduced, adding approximately 26 percent more image to your HDTV, all framed as originally intended. The full list of IMAX Digital-compatible films coming to Disney+ later this week include: Ant-Man and the Wasp, Avengers: Endgame, Avengers: Infinity War, Black Panther, Black Widow, Captain America: Civil War, Captain Marvel, Doctor Strange, Guardians of the Galaxy, Guardians of the Galaxy Vol. 2, Iron Man, Shang-Chi and the Legend of the Ten Rings, and Thor: Ragnarok.

France will start building its first new nuclear reactors in decades as part of efforts to meet its promises to reduce planet-warming emissions, French President Emmanuel Macron announced Tuesday. The Associated Press reports: He spoke as climate negotiators in Glasgow debate how to speed up efforts against climate change, and amid concerns around Europe about recent spikes in energy prices and the continent's dependence on global gas and oil producers, including Russia. "To guarantee France's energy independence, to guarantee our country's electricity supply, and to reach our goals -- notably carbon neutrality in 2050 -- we will for the first time in decades revive the construction of nuclear reactors in our country, and continue to develop renewable energy," Macron said in a televised address. He did not give any details of the plans.

Microsoft is going head to head with Chromebooks with a new $249 Surface Laptop SE, its most affordable Surface yet. While the software giant has attempted to compete with the popularity of Chrome OS in US schools for years, the Surface Laptop SE is the company's first true Chromebook competitor. From a report: Surface Laptop SE will be sold exclusively to schools and students, starting at $249. It's part of a much broader effort with Windows 11 SE, a new student edition designed to compete with Chrome OS that will ship on a range of low-cost laptops in the coming months. Surface Laptop SE is every bit the low-cost Windows device you'd expect to see for $249.

While it retains the same keyboard and trackpad found on Microsoft's Surface Laptop Go, the all-plastic body houses an 11.6-inch display running at just a 1366 x 768 resolution. This is the first 16:9 Surface device in more than seven years, after Microsoft switched to 3:2 for its Surface line with the Surface Pro 3 launch in 2014. The screen looks like the biggest drawback on this device, particularly as we weren't fans of the low-resolution screen (1536 x 1024) found on the $549 Surface Laptop Go. Lenovo's Chromebook Duet ships with a better 10.1-inch (1920 x 1200) display for the same $249 price as the Surface Laptop SE. Intel's Celeron N4020 or N4120 power the Surface Laptop SE, combined with 4GB / 8GB of RAM and 64GB or 128GB of eMMC storage.

Japan will create a scheme to subsidize construction of domestic chip factories with a new plant planned by Taiwan's TSMC likely to be the first recipient, the Nikkei newspaper reported on Monday. Reuters reports: The government will set aside several hundreds of billion yen under this year's supplementary budget to create a pool of funds at NEDO, a state-run body promoting research and development on energy and industrial technology, the paper said. Companies will be eligible for the subsidies on condition they ramp up chip production in times of short supply, the Nikkei said without citing sources.

The government is likely to subsidise up to half of TSMC's estimated 1-trillion-yen ($8.82 billion) investment for building a chip plant in Kumamoto, southern Japan, the Nikkei said. The plant in Kumamoto, southern Japan, is expected to produce semiconductors for automobiles, camera image sensors and other products which have been hit by a global chip shortage, and is likely to start operations by 2024, the paper said.

On Friday, a transparency activist group known as Distributed Denial of Secrets (DDoSecrets) posted a 1.8-terabyte trove of police helicopter footage to its website. "DDoSecrets cofounder Emma Best says that her group doesn't know the identity of the source who shared the data and that no affiliation or motivation for leaking the files was given," reports Wired. "The source simply said that the two police departments were storing the data in unsecured cloud infrastructure." Techdirt reports: The DDoS release shows law enforcement agencies aren't just deploying choppers to keep an eye on suspects in motion. They're also using them to engage in extended surveillance of people suspected of nothing, hovering over large gatherings and deploying infrared cameras to peer inside of buildings just for the fuck of it. Putting your stuff in the cloud means opening up additional attack vectors for those seeking your secrets. That appears to be the root source of this new leak. What a time to be alive!

Talking at the Web Summit in Lisbon, Arm CEO Simon Segars said this chip-supply crisis was the worst he'd ever seen (according to an EE Times article shared by Slashdot reader dkatana): The most important thing to do to get out of the woods in this situation and minimize similar ones in the future, he argued, is to improve collaboration between all players in the ecosystem. "We need better collaboration across all players in the supply chain. So, make sure we understand the bottlenecks and build resilience into this supply chain in a steady state that works okay. But when you get an event and obviously the pandemic was a Black Swan event, like no other, it froze things off the hillside, and it's very hard to recover."

Segars is optimistic that current and future investments would ease the supply chain in the short term, but he is also cautious about not creating huge expectations. "About $2 billion a week is going to be spent for the next couple of years to add capacity and build new facilities. And that's going to add about 50 percent additional capacity over the next five years...."

Segars predicted next year's Christmas might be much better for gift givers, but that consumers might still consider starting shopping early. And prices might not come down for a while. What is essential, Segars said, is to be patient, collaborate and invest. "Where are we going to be next Christmas? I expect these supply chain constraints to be a little better, but [they] won't be completely fixed because this isn't a short-term problem with a short-term solution. Billions of dollars are going to need to be spent in the coming years. And the decisions that we make today are going to affect the supply of this life, critical materials, semiconductors, over the next decade.

"Will we get this right? Will we spend enough? We spent too much, but we accidentally break the industries? That remains to be seen. That is the challenge that the industry is stepping up to" he added. "And in collaboration, across suppliers and customers and governments, we absolutely have to get it right!"
Segars also pointed out that it's hard to expand wafer production because there's so many different chemicals involved. "I mean virtually the whole periodic table that is used in making semiconductors. You need industrial style, very pure chemicals to feed into these factories downstream... So you need much more than just a chip factory to address these supply chain issues."

"In the early hours of October 30, 1961, a bomber took off from an airstrip in northern Russia and began its flight through cloudy skies over the frigid Arctic island of Novaya Zemlya," writes the Bulletin of the Atomic Scientists. Slashdot reader DanDrollette (who is also the deputy editor of The Bulletin of the Atomic Scientists) shares their report on "The secret history of the world's largest nuclear detonation, coming to light after 60 years." Slung below the plane's belly was a nuclear bomb the size of a small school bus — the largest and most powerful bomb ever created.

At 11:32 a.m., the bombardier released the weapon. As the bomb fell, an enormous parachute unfurled to slow its descent, giving the pilot time to retreat to a safe distance. A minute or so later, the bomb detonated. A cameraman watching from the island recalled:

A fire-red ball of enormous size rose and grew. It grew larger and larger, and when it reached enormous size, it went up. Behind it, like a funnel, the whole earth seemed to be drawn in. The sight was fantastic, unreal, and the fireball looked like some other planet. It was an unearthly spectacle...!

Within ten minutes, it had reached a height of 42 miles and a diameter of some 60 miles. One civilian witness remarked that it was "as if the Earth was killed." Decades later, the weapon would be given the name it is most commonly known by today: Tsar Bomba, meaning "emperor bomb...." at 50 megatons, it was more than 3,300 times as powerful as the atomic bomb that killed at least 70,000 people in Hiroshima, and more than 40 times as powerful as the largest nuclear bomb in the US arsenal today. Its single test represents about one tenth of the total yield of all nuclear weapons ever tested by all nations...

Within two years, though, the Soviet Union and the United States would sign and ratify the Limited Test Ban Treaty, prohibiting atmospheric nuclear weapons testing, and the 50-megaton bomb would fall into relative obscurity.
Drollette notes that "The United States dismissed the gigantic Tsar Bomba as a stunt, but behind the scenes it was working to build a 'superbomb' of its own."

The article argues there a lesson for our times in the 1961 episode, calling it "a potent example of how nationalism, fear, and high-technology can combine in a fashion that is ultimately dangerous, wasteful, and pointless."

Hecate Energy's plans for a 500-acre solar farm in upstate New York were cut by 50% "after facing an outcry from some in the community who feared the installation would mar the bucolic setting," reports the New York Times. (Alternate URL here.) The Copake fight mirrors similar battles raging across the country in rural areas like Lake County, Oregon; Clinton County, Ohio; and Troy, Texas. Developers say industrial-scale solar farms are needed to meet the nation's goals to mitigate the rise of climate change, but locals are fighting back against what they see as an encroachment on their pastoral settings, the loss of agricultural land and a decline in property values.

Until recently, most farms were built in the West, where abundant sunshine powers industrial-scale solar arrays and installations were farther away from sight lines. But now, with federal and state governments committing to a reduction in fossil fuels, joined by corporate giants like Amazon and Microsoft, the industry is seeking solar installations in areas where the calculus is more complicated... Improvements in the capabilities of the panels — including the development of so-called bifacial panels that capture the sun on both sides of a panel — allow for greater electricity generation in fewer panels, meaning a smaller footprint. Nonetheless, finding appropriate sites with sufficient sunlight, proximity to the grid and up-to-date infrastructure is challenging. Approximately 0.5 percent of U.S. land would need to be covered with solar panels to achieve the decarbonization goals proposed by the Biden administration in April, according to a study by the Energy Department. Urban settings usually lack enough space for significant projects; as a result, 90 percent of the suitable land sits in rural areas.

But even rural land is not entirely suitable. It needs to be in proximity to the electricity infrastructure that can add more power. The grade of land matters: Steeper slopes can be less efficient in the energy captured than flatter land. And wetlands are usually protected by federal or state law.

More important, development depends on owners willing to lease their property often for decades over the objection of neighbors.

Late Friday night U.S. Congressmen passed a long-awaited Bipartisan Infrastructure bill. "The infrastructure package contains $550 billion in entirely new investments, including money for electric-car charging stations and zero-emission school buses," reports the Washington Post.

"The spending is mostly paid for — without raising taxes. The bulk of the funding comes from repurposing unspent coronavirus relief money and tightening enforcement on reporting gains from cryptocurrency investments."

An additional $65 billion will fund broadband Internet, with new statements on the White House web site hailing the bill as "a once-in-a-generation investment in our nation's infrastructure and competitiveness" and "the largest investment in public transit in U.S. history."

This Bipartisan Infrastructure Deal will rebuild America's roads, bridges and rails, expand access to clean drinking water, ensure every American has access to high-speed internet, tackle the climate crisis, advance environmental justice, and invest in communities that have too often been left behind. The legislation will help ease inflationary pressures and strengthen supply chains by making long overdue improvements for our nation's ports, airports, rail, and roads. It will drive the creation of good-paying union jobs and grow the economy sustainably and equitably so that everyone gets ahead for decades to come. Combined with the President's Build Back Framework, it will add on average 1.5 million jobs per year for the next 10 years.
Or, as U.S. president Biden said in his own statement, the newly-passed bill "will create millions of jobs, turn the climate crisis into an opportunity, and put us on a path to win the economic competition of the 21st Century."

To address the climate crisis, the legislation "will upgrade our power infrastructure, by building thousands of miles of new, resilient transmission lines to facilitate the expansion of renewables and clean energy, while lowering costs," according to the White House's statement. "And it will fund new programs to support the development, demonstration, and deployment of cutting-edge clean energy technologies to accelerate our transition to a zero-emission economy."

More specifics from the White House:

• "Millions of Americans feel the effects of climate change each year when their roads wash out, power goes down, or schools get flooded. Last year alone, the United States faced 22 extreme weather and climate-related disaster events with losses exceeding $1 billion each — a cumulative price tag of nearly $100 billion.... The legislation makes our communities safer and our infrastructure more resilient to the impacts of climate change and cyber-attacks, with an investment of over $50 billion to protect against droughts, heat, floods and wildfires, in addition to a major investment in weatherization. The legislation is the largest investment in the resilience of physical and natural systems in American history."

• "In thousands of rural and urban communities around the country, hundreds of thousands of former industrial and energy sites are now idle — sources of blight and pollution. Proximity to a Superfund site can lead to elevated levels of lead in children's blood. The bill will invest $21 billion clean up Superfund and brownfield sites, reclaim abandoned mine land and cap orphaned oil and gas wells..."

• "U.S. market share of plug-in EV sales is only one-third the size of the Chinese EV market. That needs to change. The legislation will invest $7.5 billion to build out a national network of EV chargers in the United States. This is a critical step in the President's strategy to fight the climate crisis and it will create good U.S. manufacturing jobs. The legislation will provide funding for deployment of EV chargers along highway corridors to facilitate long-distance travel and within communities to provide convenient charging where people live, work, and shop. This investment will support the President's goal of building a nationwide network of 500,000 EV chargers to accelerate the adoption of EVs, reduce emissions, improve air quality, and create good-paying jobs across the country."

• "Broadband internet is necessary for Americans to do their jobs, to participate equally in school learning, health care, and to stay connected. Yet, by one definition, more than 30 million Americans live in areas where there is no broadband infrastructure that provides minimally acceptable speeds — a particular problem in rural communities throughout the country... The Bipartisan Infrastructure Deal will deliver $65 billion to help ensure that every American has access to reliable high-speed internet through a historic investment in broadband infrastructure deployment. The legislation will also help lower prices for internet service and help close the digital divide, so that more Americans can afford internet access...."

An anonymous reader quotes a report from Motherboard: A tweak to the iPhone's repairability that has been long prophesied and feared has finally come to pass, giving staggering new urgency for legislation that makes repair more accessible: The iPhone 13's screen cannot be replaced without special software controlled by Apple. This is a devastating blow to independent repair shops, who make the vast majority of their money doing screen replacements, and, specifically, make the vast majority of their money doing iPhone screen replacements. According to iFixit, replacing the screen on an iPhone 13 disables Face ID functionality. That's because the screen itself is paired to a small microcontroller attached to the display. Replacing a cracked screen with a new screen will disable this pairing, thus breaking a core piece of functionality in the phone. An authorized Apple repair tech can pair a new screen to an iPhone with the click of a few buttons using proprietary Apple tech. Everyone else will have a much harder time. "It is still possible to change a screen on an iPhone 13," notes Motherboard. "The difference is that in order to do so now, this microcontroller needs to be removed from the broken screen and resoldered onto the new screen (after the existing microcontroller on that screen is removed). Doing this requires microsoldering, which requires the use of a microscope and a highly skilled technician."

In an email to Motherboard, iFixit CEO Kyle Wiens said: "This is a clear case of a manufacturer using their power to prevent competition and monopolize an industry. Society loses: small repair shops will wither and fade away and consumers will be left with no choice but to pay top dollar for repairs or replace their device."

A modified consumer drone was used in an attack on an electrical substation in the US last year, according to a report from the FBI, Department of Homeland Security and National Counterterrorism Center. New Scientist reports: The report, which is being circulated to law enforcement agencies in the US, highlights the incident at a substation in Pennsylvania last year as the first known use of a drone to target energy infrastructure in the US. The location isn't specifically identified, but the drone crashed without causing damage. The drone was modified with a trailing tether supporting a length of copper wire. If the wire had come into contact with high-voltage equipment it could have caused a short circuit, equipment failures and possibly fires.

Electrical substations are normally protected by fences and other barriers, but Zak Kallenborn at the National Consortium for the Study of Terrorism and Responses to Terrorism in Maryland says these may not be sufficient against drones. [...] Counter-drone jammers are deployed at some locations but cannot defend every electrical substation, due to both cost and limitations on where they can be used. Kallenborn notes that while such drones only carry a tiny payload compared to a car bomb, they can cause a disproportionate amount of damage by targeting vulnerable spots. "Critical infrastructure owners and operators need to identify critical, sensitive components where small charges can cause significant harm to the facility's operation," says Kallenborn.

An anonymous reader quotes a report from PCMag: Intel has posted a release that the hybrid CPU core architecture on Alder Lake can be incompatible with certain games, specifically some protected by the anti-piracy DRM software from Denuvo. This was confirmed in our review of the Core i9-12900K when we tried to run the hit AAA Ubisoft title Assassin's Creed: Valhalla, part of our processor benchmark suite. The game would crash halfway through the test run, or simply not boot in at all. The errors occur because Denuvo's DRM software will mistakenly think the so-called "Performance-cores" and "Efficiency-cores" (P-cores and E-cores) on the chip belong to two separate PCs, when in reality the two types of processing cores are running on the same Alder Lake processor. (This P-core/E-core design is a new trait of Intel's chips with Alder Lake.)

Intel was originally mum on which specific games were affected, making it unclear the scale of the problem; the company cited "32" in pre-release briefings to the tech press. Whether these would be marginal titles or blockbusters we did not know, as hundreds of games use the Denuvo DRM scheme. But on Thursday, the company published a list of every PC title known to it that has incompatibility issues with Alder Lake. It spans 51 games, including For Honor, Mortal Kombat 11, Star Wars Jedi Fallen Order, and Shadow of the Tomb Raider, as well as the Assassin's Creed: Valhalla game we observed the issue on. Intel says it is working with game developers to roll out a software fix, although the company notes that some of the affected DRM-protected titles can run fine, so long as your PC is on Windows 11. In the meantime, the company says it has come up with a workaround that can run any of the affected games on Alder Lake. But it'll do so by placing the efficiency cores on standby. "According to Intel, 22 of the games won't work on Alder Lake under both Windows 10 and Windows 11," adds PCMag. "[T]he remaining 29 titles [...] will suffer incompatibility problems, but only when run on Windows 10. So owners can also solve the issue by updating their PCs to Windows 11 or using the Scroll Lock workaround if available."

MojoKid writes: After months of speculation and early look teases, Intel's 12th Gen Core processors are finally ready for prime time. Today marks the embargo lift for independent reviews of Alder Lake and it's clear Chipzilla is back and bringing the fight again versus chief rival AMD. Intel 12th Gen Core processors incorporate two new CPU core designs, dubbed Efficiency (E-core) and Performance (P-core). In addition to this new hybrid core architecture, 12th Gen Core processors and the Z690 motherboard chipset platform also feature support for the latest memory and IO technologies, including PCI Express Gen 5, DDR5, Thunderbolt 4 and Wi-Fi 6E. The new Core i9-12900K features a monolithic, 16-core (24-thread) die with 8 Performance cores and 8 Efficiency cores, while the Core i5-12600K has 10 cores/16-threads, comprised of 6 P-cores and 4 E-cores. Alder Lake E-cores don't support HyperThreading but P-cores can process two threads simultaneously while E-cores can manage only one, hence the asymmetric core counts.

In the benchmarks, the 16-core Core i9-12900K doesn't sweep AMD's 16-core Ryzen 9 5950X across the board in multi-threaded tests, but it certainly competes very well and notches plenty of victories. In the lightly-threaded tests though, it's a much clearer win for Intel and gaming is an obvious strong point as well. Alder Lake's performance cores are as fast as they come. The $589 (MSRP) 16-core Core i9-12900K competes well with the $750 16-core Ryzen 9 5950X, and the $289 10-core Core i5-12600K has a lower MSRP than a $299 6-core Ryzen 5 5600X. The new Core i5's power and performance look great too, especially when you consider this $289 chip outruns Intel's previous-gen flagship Core i9-11900K more often than not, and it smokes a Ryzen 5 5600X.

Apple is in discussions with Samsung and LG over applying OLED displays with a two-stack tandem structure to future iPad and MacBook models, but the devices are likely several years away from launch, according to Korean website The Elec. MacRumors reports: The report indicates that a two-stack tandem structure would consist of two layers of red, green, and blue emission layers, allowing for the future iPad and MacBook models to have significantly brighter displays with up to double the luminance. Apple's current OLED devices like the iPhone have a single-stack structure, the report adds. Given that OLED technology is expensive, it's likely the displays will be used on future iPad Pro and MacBook Pro models specifically. The report claims the future iPads will come in 11-inch and 12.9-inch sizes, which are indeed the current iPad Pro sizes.

The report claims the two-stack iPad displays will also be low-power LTPO panels, which could allow for a wider ProMotion refresh rate range between 10Hz and 120Hz, in line with the iPhone 13 Pro models. iPad Pro models have already supported ProMotion since 2017, but with a refresh rate between 24Hz and 120Hz. Timing remains a big question mark. While some earlier reports claimed the first iPad with an OLED display was slated for release in 2022, today's report claims the timeframe has been pushed back to late 2023 or 2024. The first MacBook with an OLED display might follow in 2025, but this plan could be postponed further, the report adds.

An anonymous reader quotes a report from Ars Technica: Carbon capture. Hydrogen production. Synthetic fuels. All of these technologies have been proposed as potential resources for dealing with the crises created by our carbon dioxide emissions. While they have worked in small pilot demonstrations, most of them haven't demonstrated that they can scale to provide the economical solutions we need. In the meantime, a group of European researchers sees the methods as part of a single coherent production platform, one that goes from sunlight and air to kerosene. Thanks to a small installation on the roof of a lab in Zurich, the team has been producing small amounts of different fuels using some mirrors and a handful of reaction chambers. While the full production process would also need to demonstrate that it can scale, the researchers calculate that the platform could fuel the entire commercial aircraft industry using a small fraction of the land in the Sahara.
[...]
Overall, the results are clear: The process can work, but it's not productive enough to matter in its current state, so a large portion of the paper considers optimization and scale. Optimization is mostly a matter of many little improvements, like the better use of waste heat to ensure all the necessary heat is provided by the solar reflectors. Other targets include better catalysts and more efficient means of storing the gasses between steps. Then there's a matter of scale. To fuel a daily round-trip flight between New York City and London, the researchers estimate, it would take 10 mirror farms directing sunlight at reaction chambers in an area that gets strong and consistent sunlight. That translates to covering around 3.8 square kilometers of the desert with mirrors. (For context, that's about a quarter of the size of California's Ivanpah solar facility.) Providing for all of commercial aviation's fuel needs would require taking over half of one percent of the surface of the Sahara Desert. And that means a lot of mirrors.

The researchers suggest we will likely see the sort of dramatic cost reductions seen in other renewable resources, including technologies like concentrating solar power. That mirror-based tech saw prices drop by 60 percent over a recent 15-year period. But it's questionable whether the sorts of price drops we've seen with photovoltaics are possible, given the large material costs of all those mirrors and their associated hardware, plus the maintenance costs of keeping them clean. The flipside is that concentrating solar power costs have continued to come down, and a lot of those savings could probably be applied to heat-driven chemistry like this. And it's possible that this basic concept -- solar-powered green chemistry -- could be adapted to produce fuels with a higher value than kerosene.

Although PCs are still selling at a greater volume than before the COVID-19 pandemic, demand is starting to drop. In Q3 2021, shipments of laptops, desktops, and tablets dropped 2 percent compared to Q3 2020, according to numbers that researcher Canalys shared on Monday. Interest in Chromebooks dropped the most, with a reported decline as high as 36.9 percent. Demand for tablets also fell, showing a 15 percent year-on-year decline, according to Canalys. From a report: Both Canalys and the IDC's Worldwide Quarterly Personal Computing Device Tracker shared Q3 numbers for Chromebooks and tablets on Monday. Canalys said 5.8 million Chromebooks shipped globally during this time, while the IDC said the number was 6.5 million. Both pointed to a huge decline compared to Q3 2020. Canalys reported the drop at 36.9 percent, and IDC pegged it at 29.8 percent. Canalys said that Q3 Chromebook sales took a "major downturn" as the education markets in the US, Japan, and elsewhere became saturated. Demand lessened as government programs supporting remote learning went away, the research group said. After reaching a high of 18 percent market share since the start of 2020, Chromebooks reportedly represented just 9 percent of laptop shipments in Q3 2021.
