Global PC Market Swells by 55% in Q1 2021 To 82.7 Million (canalys.com) 11

The latest data from research firm Canalys shows continued strength in the worldwide PC market in the first quarter of 2021, with shipments of desktops and notebooks, including workstations, up 55% year on year. From the report: Though this growth rate was buoyed by a weak Q1 2020, total shipments of 82.7 million units is still impressive, and the highest Q1 shipment number since 2012. Backlogs on orders from 2020, particularly for notebooks, were a key driver, though new demand is also a factor as smaller businesses begin their recoveries. Shipments of notebooks and mobile workstations increased 79% year on year to reach 67.8 million units. Desktops improved slightly at the start of 2021 after a string of poor quarters in 2020, with the level of shipment decline easing. Shipments of desktop and desktop workstations fell 5% year on year to 14.8 million units.

The strong recovery from a weak Q1 2020 saw all vendors in the top five achieve double-digit year-on-year shipment growth. Lenovo maintained pole position in the PC market, securing a 25% market share and posting year-on-year growth of 61%, with shipments of 20.4 million units. HP, spurred by strong Chromebook shipments, came second with total shipments of 19.2 million units, a 64% increase on Q1 2020. Dell lost market share against Q4, but took third place in the rankings, growing shipments 23% year on year to hit 12.9 million units. Apple and Acer made up the rest of the top five, shipping 6.6 million and 5.7 million units to enjoy the highest and second-highest annual growth respectively. Cumulatively, the top five vendors accounted for 78.5% of all PC shipments in Q1 2021.

Tesla Drastically Increases Price of Solar Roof (electrek.co) 180

Tesla appears to have drastically increased the price of its Solar Roof tiles in an update to its configurator and quote estimates. Electrek reports: After years of delays, the Tesla Solar Roof is finally gaining momentum with a sharp rise in installations over the last few quarters. The increased deployment came after Tesla launched version 3 of its Solar Roof tiles, which brought a significant price decrease through optimization and faster installation process. Tesla kept refining the product and changed its online cost estimates a few times, decreasing the price again last summer.

But now Tesla appears to have changed course and significantly increased the price of its solar roof in its online configurator. Several Electrek readers and prospective solar roof buyers reached out this weekend to let us know that they are seeing higher prices for the same quotes. Last summer, a quote for a 3,947-square-foot roof with a 12,3 kW solar roof tile system was $54,966 before incentives. Now the Tesla Solar Roof configurator shows prices between $79,938 and $100,621 for the same size roof. While this is a sharp increase in price, Tesla also appears to try to make its online quotes more accurate with a new "roof complexity" factor. [...] However, in this case, the least to the most complex options all result in higher prices than previously quoted for the same address with the same square footage.

Nvidia To Make CPUs, Going After Intel (bloomberg.com) 111

Nvidia said it's offering the company's first server microprocessors, extending a push into Intel's most lucrative market with a chip aimed at handling the most complicated computing work. Intel shares fell more than 2% on the news. From a report: The graphics chipmaker has designed a central processing unit, or CPU, based on technology from Arm, a company it's trying to acquire from Japan's SoftBank Group. The Swiss National Supercomputing Centre and U.S. Department of Energy's Los Alamos National Laboratory will be the first to use the chips in their computers, Nvidia said Monday at an online event. Nvidia has focused mainly on graphics processing units, or GPUs, which are used to power video games and data-heavy computing tasks in data centers. CPUs, by contrast, are a type of chip that's more of a generalist and can do basic tasks like running operating systems. Expanding into this product category opens up more revenue opportunities for Nvidia.

Founder and Chief Executive Officer Jensen Huang has made Nvidia the most valuable U.S. chipmaker by delivering on his promise to give graphics chips a major role in the explosion in cloud computing. Data center revenue contributes about 40% of the company's sales, up from less than 7% just five years ago. Intel still has more than 90% of the market in server processors, which can sell for more than $10,000 each. The CPU, named Grace after the late pioneering computer scientist Grace Hopper, is designed to work closely with Nvidia graphics chips to better handle new computing problems that will come with a trillion parameters. Systems working with the new chip will be 10 times faster than those currently using a combination of Nvidia graphics chips and Intel CPUs. The new product will be available at the beginning of 2023, Nvidia said.

Iran Nuclear Facility Suffers Blackout, Cyberattack Suspected (apnews.com) 117

While difficult negotiations continue over a deal to curtail Iran's nuclear ambitions, this morning Iran suddenly experienced a blackout at its underground Natanz atomic facility, the Associated Press reports: While there was no immediate claim of responsibility, suspicion fell immediately on Israel, where its media nearly uniformly reported a devastating cyberattack orchestrated by the country caused the blackout. Israeli Prime Minister Benjamin Netanyahu later Sunday night toasted his security chiefs, with the head of the Mossad, Yossi Cohen, at his side on the eve of his country's Independence Day... Netanyahu, who also met Sunday with U.S. Defense Secretary Lloyd Austin, has vowed to do everything in his power to stop the nuclear deal...

Natanz has been targeted by sabotage in the past. The Stuxnet computer virus, discovered in 2010 and widely believed to be a joint U.S.-Israeli creation, once disrupted and destroyed Iranian centrifuges at Natanz amid an earlier period of Western fears about Tehran's program. Natanz suffered a mysterious explosion at its advanced centrifuge assembly plant in July that authorities later described as sabotage. Iran now is rebuilding that facility deep inside a nearby mountain. Iran also blamed Israel for the November killing of a scientist who began the country's military nuclear program decades earlier.

Multiple Israeli media outlets reported Sunday that an Israeli cyberattack caused the blackout in Natanz. Public broadcaster Kan said the Mossad was behind the attack. Channel 12 TV cited "experts" as estimating the attack shut down entire sections of the facility. While the reports offered no sourcing for their information, Israeli media maintains a close relationship with the country's military and intelligence agencies...

On Tuesday, an Iranian cargo ship said to serve as a floating base for Iran's paramilitary Revolutionary Guard forces off the coast of Yemen was struck by an explosion, likely from a limpet mine. Iran has blamed Israel for the blast. That attack escalated a long-running shadow war in Mideast waterways targeting shipping in the region.

Japan Poised to Approve Release of Fukushima Nuclear Plant Water Into the Ocean (japantoday.com) 99

New submitter evaverdeazul shared this report from Japan Today: The Japanese government is poised to release treated radioactive water accumulated at the crippled Fukushima nuclear plant into the sea despite opposition from fishermen, sources familiar with the matter said Friday. It will hold a meeting of related ministers as early as Tuesday to formally decide on the plan, a major development following over seven years of discussions on how to discharge the water used to cool down melted fuel at the Fukushima Daiichi plant.

The treated water containing radioactive tritium, a byproduct of nuclear reactors, is said to pose little risk to human health because even if one drinks the water, so long as the tritium concentration is low, the amounts of tritium would not accumulate in the body and would soon be excreted. There is also no risk of external exposure even if the water comes in contact with skin. Still, concerns remain among Japan's fisheries industry and consumers as well as neighboring countries such as South Korea and China.

The government has said it cannot continue postponing a decision on the disposal issue, given that the storage capacity of water tanks at the Fukushima complex is expected to run out as early as fall next year. It asserts that space needs to be secured on the premises, such as for keeping melted fuel debris that will be extracted from the damaged reactors, to move forward with the decades-long process of scrapping the complex.

Plant operator Tokyo Electric Power Company Holdings Inc (TEPCO) says it will take around two years for the discharge to start.

Data Center Backup Generator Kicks In During Power Outage and Catches Fire (theregister.com) 71

Joe_Dragon shares a report from The Register: A power outage kicked off a fire in web hosting biz WebNX's Ogden data center in Utah on Sunday, knocking the facility offline temporarily and leaving several servers in need of a rebuild. Kevin Brown, Fire Marshal for the US city's Fire Department told The Register in a phone interview that firefighters responded to a call on Sunday evening. The fire, he said, "originated in a generator in the building and spread to several servers." Brown said the facility's fire suppression system contained the blaze and that fire department personnel assisted with the cleanup. He said power was cut to the building until an electrical engineer could inspect the facility to make sure current could be restored safely, which he added is standard procedure. He also confirmed that some of Ogden City's IT services were down on Sunday and Monday as a result of the data center fire. "Sunday afternoon the city power was disrupted and, as designed, our backup generators automatically switched on," the company said in a Facebook post. "However, during that transition, one of our backup generators that had been recently tested and benchmarked specifically for this situation experienced a catastrophic failure, caught fire, and as a result initiated the fire suppression protocol."

"Some servers will have an extended outage as they may require rebuilds due to some water damage. Those builds have a high probability that data is intact." They added: "Customer's servers in one of our main bays were exposed to water and possible damage may have occurred. No fire damage was inflicted on customer servers."

TAE Technologies Claims Landmark In Fusion Energy, Sees Commercialization By 2030 (techcrunch.com) 118

TAE Technologies, a 20-year-old fusion energy technology developer, is claiming to have hit a milestone in the development of a new technology for generation power from nuclear fusion. The company said its reactors could be operating at commercial scale by the end of the decade, thanks to its newfound ability to produce stable plasma at temperatures over 50 million degrees (nearly twice as hot as the sun). TechCrunch reports: For TAE Technologies, the achievement serves as a validation of the life's work of Norman Rostoker, one of the company's co-founders who had devoted his life to fusion energy research and died before he could see the company he helped create reach its latest milestone. "This is an incredibly rewarding milestone and an apt tribute to the vision of my late mentor, Norman Rostoker," said TAE's current chief executive officer, Michl Binderbauer, in a statement announcing the company's achievement. "Norman and I wrote a paper in the 1990s theorizing that a certain plasma dominated by highly energetic particles should become increasingly better confined and stable as temperatures increase. We have now been able to demonstrate this plasma behavior with overwhelming evidence. It is a powerful validation of our work over the last three decades, and a very critical milestone for TAE that proves the laws of physics are on our side."

Rostoker's legacy lives on inside TAE through the company's technology platform, called, appropriately, "Norman." In the last 18 months that technology has demonstrated consistent performance, reaching over 50 million degrees in several hundred test cycles. Six years ago, the company had proved that its reactor design could sustain plasma indefinitely -- meaning that once the switch is flipped on a reaction, that fusion reaction can continue indefinitely. Now, the company said, it has achieved the necessary temperatures to make its reactors commercially viable. It's with these milestones behind it that TAE was able to raise an additional $280 million in financing, bringing its total up to $880 million and making it one of the best financed private nuclear fusion endeavors in the world.

Amazon Warns Texas: Don't Pass Bill That Would Drive Up Wind Power Costs (arstechnica.com) 155

Fallout from Texas' statewide power outages in February continues to spread. Today, the Texas House of Representatives is scheduled to debate a bill that would require power producers to bear the costs of services that help keep the electrical grid stable. From a report: If the bill passes, it would "unfairly shift the cost of ancillary electric services exclusively onto renewable generators rather than all the beneficiaries," according to a letter written by the Partnership for Renewable Energy Finance (PREF), an industry group, and signed by Amazon, Berkshire Hathaway Energy, Goldman Sachs, and a number of other firms. Amazon and other big tech firms have invested heavily in renewable power, seeking to spruce up their images while cutting their power bills. Costs for wind and solar have dropped precipitously in recent years, making investments in wind farms and solar plants attractive to power-hungry data center operators like Amazon, Facebook, and Google.

"It is important to note that these changes neither enhance electric reliability nor lower consumer costs," the letter states. "They appear to be premised on the assumption that renewable energy was disproportionately responsible for the state's February power outages, a thesis that has been unequivocally discredited." The bill would require the grid operator, the Electric Reliability Council of Texas (ERCOT), to "directly assign" ancillary service costs to wind and solar power, specifically. The PREF letter counters that not only do all generators utilize ancillary services, but costs for those services have remained flat over the last decade while wind and solar have grown by more than 250 percent.

Saskatchewan To Roll Out $150 Annual Tax For Passenger Electric Vehicles (www.cbc.ca) 215

innocent_white_lamb writes: The Saskatchewan government will implement a new tax for passenger electric vehicles. The announcement was made Tuesday. The new $150 annual tax on passenger electric vehicles (EVs) will take effect Oct. 1, 2021. The government said the reason for this tax is that EVs do not contribute to highway maintenance through the provincial fuel tax. The new tax will be collected when the vehicle is registered. The province says it will continue to examine the future potential for expanding the EV tax to commercial vehicles and inter-jurisdictional trucking. The province will also consider options to apply a tax at EV charging stations.

Great Britain's Electricity System Has Greenest Day Ever Over Easter (theguardian.com) 128

An anonymous reader quotes a report from The Guardian: Great Britain's electricity system recorded its greenest ever day over the Easter bank holiday as sunshine and windy weather led to a surge in renewable energy. The power plants generating electricity in England, Scotland and Wales produced only 39g of carbon dioxide for every kilowatt-hour of electricity on Monday, according to National Grid's electricity system operator, the lowest carbon intensity recorded since National Grid records began in 1935.

On Easter Monday, wind turbines and solar farms generated 60% of all electricity as households enjoyed a bank holiday lunch. At the same time the UK's nuclear reactors provided 16% of the electricity mix, meaning almost 80% of the grid was powered from low-carbon sources. The low-carbon power surge, combined with lower than average demand for electricity over the bank holiday, kept gas-fired power in Great Britain to 10% of the electricity mix and caused the "carbon intensity" of the electricity system to plummet to its lowest on record.

GM Is Building An Electric Chevy Silverado With 400 Miles of Range (theverge.com) 112

General Motors confirmed it's making an all-electric version of the Chevy Silverado pickup truck with around 400 miles of range on a full charge. The Verge reports: The company did not immediately say when the electric Silverado will go on sale, but GM president Mark Reuss said at an event on Tuesday that the company will also make commercial fleet-focused versions of the truck. The electric Silverado will be made at "Factory Zero," the recently rebranded Detroit-Hamtramck plant dedicated to EVs and AVs that GM is currently retooling at a cost of more than $2 billion. It's the same plant where GM will build the all-electric Hummer SUV and Hummer pickup.

The Silverado EV will undoubtedly be a flagship vehicle of the custom electric vehicle platform GM announced last year, called Ultium. Designed to be modular, the Ultium platform is what will power most of GM's forthcoming electric vehicles. The company has promised the platform will be able to provide as much as 400 miles of range in the biggest configurations, and that the trucks built on Ultium will feature 800-volt architecture that allows for really fast charging.

Why Shortages of a $1 Chip Sparked Crisis in Global Economy (bloomberg.com) 117

To understand why the $450 billion semiconductor industry has lurched into crisis, a helpful place to start is a one-dollar part called a display driver. From a report: Hundreds of different kinds of chips make up the global silicon industry, with the flashiest ones from Qualcomm and Intel going for $100 apiece to more than $1,000. Those run powerful computers or the shiny smartphone in your pocket. A display driver chip is mundane by contrast: Its sole purpose is to convey basic instructions for illuminating the screen on your phone, monitor or navigation system. The trouble for the chip industry -- and increasingly companies beyond tech, like automakers -- is that there aren't enough display drivers to go around. Firms that make them can't keep up with surging demand so prices are spiking. That's contributing to short supplies and increasing costs for liquid crystal display panels, essential components for making televisions and laptops, as well as cars, airplanes and high-end refrigerators.

"It's not like you can just make do. If you have everything else, but you don't have a display driver, then you can't build your product," says Stacy Rasgon, who covers the semiconductor industry for Sanford C. Bernstein. Now the crunch in a handful of such seemingly insignificant parts -- power management chips are also in short supply, for example -- is cascading through the global economy. Automakers like Ford Motor, Nissan Motor and Volkswagen have already scaled back production, leading to estimates for more than $60 billion in lost revenue for the industry this year. The situation is likely to get worse before it gets better.

Intel MacBook Pro Owner Adds Water Cooling To Silence Noisy Fans, Boost Performance (macrumors.com) 48

An inventive MacRumors forums member has successfully retrofitted a water-cooling system to their 15-inch Intel-based MacBook Pro, thereby eliminating fan noise and boosting performance. From the report: MacRumors forums member "theodric" explained that the noise of their MacBook Pro's fans had become disruptive during conference calls, so amid ordering an M1 MacBook Air, they decided to fit a water cooling system to their machine. theodric used inexpensive parts such as Bitcoin ASIC miner blocks from AliExpress, an Aquastream XT Ultra water pump, and a Zalman radiator and reservoir from 2005 to create the system.

High-transmissivity thermal pads were added between the case shell and various motherboard components to conduct heat away from the MacBook Pro and into the water cooling system. The thermal shielding from the bottom of the case was also removed, as well as the feet, to ensure full contact with the new cooling plates. The pump, which requires Windows software to operate, was run via a virtual machine, and a Raspberry Pi was used for monitoring. theodric says that they have "hardly heard the fan since I started using it" and have seen benchmark scores significantly improve under the system. See theodric's full post for more information about the ambitious project.

What We're Expecting From Google's Custom 'Whitechapel' SoC In the Pixel 6 (arstechnica.com) 16

An anonymous reader quotes a report from Ars Technica: It sounds like this custom Google SoC-powered Pixel is really going to happen. Echoing reports from about a year ago, 9to5Google is reporting that the Pixel 6 is expected to ship with Google's custom "Whitechapel" SoC instead of a Qualcomm Snapdragon chip. The report says "Google refers to this chip as 'GS101,' with 'GS' potentially being short for 'Google Silicon.'" It also notes that chip will be shared across the two Google phones that are currently in development, the Pixel 6 and something like a "Pixel 5a 5G." 9to5 says it has viewed documentation that points to Samsung's SLSI division (Team Exynos) being involved, which lines up with the earlier report from Axios saying the chip is "designed in cooperation with Samsung" and should be built on Samsung's 5nm foundry lines. 9to5Google says the chip "will have some commonalities with Samsung Exynos, including software components."

XDA Developers says it can corroborate the report, saying, "According to our source, it seems the SoC will feature a 3 cluster setup with a TPU (Tensor Processing Unit). Google also refers to its next Pixel devices as 'dauntless-equipped phones,' which we believe refers to them having an integrated Titan M security chip (code-named 'Citadel')." A "3 cluster setup" would be something like how the Snapdragon 888 works, which has three CPU core sizes: a single large ARM X1 core for big single-threaded workloads, three medium Cortex A78 cores for multicore work, and four Cortex A55 cores for background work. The Pixel 6 should be out sometime in Q4 2021, and Pixel phones always heavily, heavily leak before they launch. So I'm sure we'll see more of this thing soon.
"I think the biggest benefit we'll see from a Google SoC is an expanded update timeline," writes Ron Amadeo. "Android updates go a lot smoother when you get support from the SoC manufacturer, but Qualcomm abandons all its chips after the three-year mark for major updates. This lack of support makes updates significantly harder than they need to be, and today that's where Google draws the line at updates."

"Beyond easier updates, I don't know that we can expect much from Whitechapel," adds Amadeo, noting that lots of Android manufacturers have made their own chips but none of them have been able to significantly beat Qualcomm. "It's hard to be bullish on Google's SoC future when the company doesn't seem to be making the big-money acquisitions and licensing deals that Apple, Qualcomm, and Samsung are making. But at least it's a start."

How Children Beating Up a Robot Inspired a New Escape Maneuver System (ieee.org) 87

Long-time Slashdot reader AmiMoJo quotes a classic article from IEEE Spectrum: A study by a team of Japanese researchers shows that, in certain situations, children are actually horrible little brats^W^W^W may not be as empathetic towards robots as we'd previously thought, with gangs of unsupervised tykes repeatedly punching, kicking, and shaking a robot in a Japanese mall...

The Japanese group didn't just document the bullying behavior, though; they wanted to find clever ways of helping the robot avoid the abusive situations. They started by developing a computer simulation and statistical model of the children's abuse towards the robot, showing that it happens primarily when the kids are in groups and no adults are nearby. Next, they designed an abuse-evading algorithm to help the robot avoid situations where tiny humans might gang up on it. Literally tiny humans: the robot is programmed to run away from people who are below a certain height and escape in the direction of taller people.

When it encounters a human, the system calculates the probability of abuse based on interaction time, pedestrian density, and the presence of people above or below 1.4 meters (4 feet 6 inches) in height. If the robot is statistically in danger, it changes its course towards a more crowded area or a taller person. This ensures that an adult is there to intervene when one of the little brats decides to pound the robot's head with a bottle (which only happened a couple times).
