Father of SQL Says Yes to NoSQL (theregister.com) 75

An anonymous reader shared this report from the Register: The co-author of SQL, the standardized query language for relational databases, has come out in support of the NoSQL database movement that seeks to escape the tabular confines of the RDBMS. Speaking to The Register as SQL marks its 50th birthday, Donald Chamberlin, who first proposed the language with IBM colleague Raymond Boyce in a 1974 paper [PDF], explains that NoSQL databases and their query languages could help perform the tasks relational systems were never designed for. "The world doesn't stay the same thing, especially in computer science," he says. "It's a very fast, evolving, industry. New requirements are coming along and technology has to change to meet them, I think that's what's happening. The NoSQL movement is motivated by new kinds of applications, particularly web applications, that need massive scalability and high performance. Relational databases were developed in an earlier generation when scalability and performance weren't quite as important. To get the scalability and performance that you need for modern apps, many systems are relaxing some of the constraints of the relational data model."

[...] A long-time IBMer, Chamberlin is now semi-retired, but finds time to fulfill a role as a technical advisor for NoSQL company Couchbase. In the role, he has become an advocate for a new query language designed to overcome the "impedance mismatch" between data structures in the application language and a database, he says. UC San Diego professor Yannis Papakonstantinou has proposed SQL++ to solve this problem, with a view to addressing impedance mismatch between heavily object-based JavaScript, the core language for web development and the assumed relational approach embedded in SQL. Like C++, SQL++ is designed as a compatible extension of an earlier language, SQL, but is touted as better able to handle the JSON file format inherent in JavaScript. Couchbase and AWS have adopted the language, although the cloud giant calls it PartiQL.

At the end of the interview, Chamblin adds that "I don't think SQL is going to go away. A large part of the world's business data is encoded in SQL, and data is very sticky. Once you've got your database, you're going to leave it there. Also, relational systems do a very good job of what they were designed to do...

"[I]f you're a startup company that wants to sell shoes on the web or something, you're going to need a database, and one of those SQL implementations will do the job for free. I think relational databases and the SQL language will be with us for a long time."

Are Small Modular Nuclear Reactors Costly and Unviable? (cosmosmagazine.com) 215

The Royal Institution of Australia is a national non-profit hub for science communication, publishing the science magazine Cosmos four times a year.

This month they argued that small modular nuclear reactors "don't add up as a viable energy source." Proponents assert that SMRs would cost less to build and thus be more affordable. However, when evaluated on the basis of cost per unit of power capacity, SMRs will actually be more expensive than large reactors. This 'diseconomy of scale' was demonstrated by the now-terminated proposal to build six NuScale Power SMRs (77 megawatts each) in Idaho in the United States. The final cost estimate of the project per megawatt was around 250 percent more than the initial per megawatt cost for the 2,200 megawatts Vogtle nuclear power plant being built in Georgia, US. Previous small reactors built in various parts of America also shut down because they were uneconomical.
The cost was four to six times the cost of the same electricity from wind and solar photovoltaic plants, according to estimates from the Australian Commonwealth Scientific and Industrial Research Organisation and the Australian Energy Market Operator. "The money invested in nuclear energy would save far more carbon dioxide if it were instead invested in renewables," the article agues: Small reactors also raise all of the usual concerns associated with nuclear power, including the risk of severe accidents, the linkage to nuclear weapons proliferation, and the production of radioactive waste that has no demonstrated solution because of technical and social challenges. One 2022 study calculated that various radioactive waste streams from SMRs would be larger than the corresponding waste streams from existing light water reactors...

Nuclear energy itself has been declining in importance as a source of power: the fraction of the world's electricity supplied by nuclear reactors has declined from a maximum of 17.5 percent in 1996 down to 9.2 percent in 2022. All indications suggest that the trend will continue if not accelerate. The decline in the global share of nuclear power is driven by poor economics: generating power with nuclear reactors is costly compared to other low-carbon, renewable sources of energy and the difference between these costs is widening.

The People Who Won't Give Up Floppy Disks (bbc.com) 96

Slashdot reader quonset writes: The last floppy disk was manufactured in 2011. Despite no new supplies being available for over a decade, there are still people, and organizations, who rely on floppy disks. Each has their own story as to why they rely on what is essentially 1970s technology.
From the BBC: Tom Persky, a US businessman, has been selling "new", as in, unopened, floppy disks for years and still finds the trade lucrative. He runs Floppydisk.com, which offers disks for about US$1 (£0.80) each, though some higher capacity versions cost up to US$10 (£8) per disk, he says. Persky has customers all over the world and you could split them roughly 50-50 into hobbyists and enthusiasts like Espen Kraft on one side, and industrial users on the other. This latter category encompasses people who use computers at work that require floppy disks to function. They are, essentially, locked in to a format that the rest of the world has largely forgotten.

"I sell thousands of floppy disks to the airline industry, still," says Persky. He declines to elaborate. "Companies are not happy about when I talk about them." But it is well-known that some Boeing 747s, for example, use floppy disks to load critical software updates into their navigation and avionics computers. While these older aircraft might not be so common in Europe or the US these days, you might find one in the developing world, for instance, Persky hints. There are also pieces of factory equipment, government systems — or even animatronic figures — that still rely on floppy disks.

And in San Francisco, the Muni Metro light railway, which launched in 1980, won't start up each morning unless the staff in charge pick up a floppy disk and slip it into the computer that controls the railway's Automatic Train Control System, or ATCS. "The computer has to be told what it's supposed to do every day," explains a spokesman for the San Francisco Municipal Transport Agency (SFMTA). "Without a hard drive, there is nowhere to install software on a permanent basis."

This computer has to be restarted in such a way repeatedly, he adds — it can't simply be left on, for fear of its memory degrading.

The article also includes this quote from a cybersecurity expert at Pen Test Partners. "If floppy was the only interface, the only way to get malware on to [the computer] would be via said floppy disk. That's quite a limiting factor for the attacker..."

'Tungsten Wall' Leads To Nuclear Fusion Breakthrough (qz.com) 45

A tokamak in France achieved a new record in fusion plasma by using tungsten to encase its reaction, which enabled the sustainment of hotter and denser plasma for longer periods than previous carbon-based designs. Quartz reports: A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA). WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak's interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible.

"These are beautiful results," said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. "We have reached a stationary regime despite being in a challenging environment due to this tungsten wall."

Google Cloud Accidentally Deletes UniSuper's Online Account Due To 'Unprecedented Misconfiguration' (theguardian.com) 52

A "one-of-a-kind" Google Cloud "misconfiguration" resulted in the deletion of UniSuper's account last week, disrupting the financial services provider's more than half a million members. "Services began being restored for UniSuper customers on Thursday, more than a week after the system went offline," reports The Guardian. "Investment account balances would reflect last week's figures and UniSuper said those would be updated as quickly as possible." From the report: The UniSuper CEO, Peter Chun, wrote to the fund's 620,000 members on Wednesday night, explaining the outage was not the result of a cyber-attack, and no personal data had been exposed as a result of the outage. Chun pinpointed Google's cloud service as the issue. In an extraordinary joint statement from Chun and the global CEO for Google Cloud, Thomas Kurian, the pair apologized to members for the outage, and said it had been "extremely frustrating and disappointing." They said the outage was caused by a misconfiguration that resulted in UniSuper's cloud account being deleted, something that had never happened to Google Cloud before.

While UniSuper normally has duplication in place in two geographies, to ensure that if one service goes down or is lost then it can be easily restored, because the fund's cloud subscription was deleted, it caused the deletion across both geographies. UniSuper was able to eventually restore services because the fund had backups in place with another provider.
"Google Cloud CEO, Thomas Kurian has confirmed that the disruption arose from an unprecedented sequence of events whereby an inadvertent misconfiguration during provisioning of UniSuper's Private Cloud services ultimately resulted in the deletion of UniSuper's Private Cloud subscription," the pair said. "This is an isolated, 'one-of-a-kind occurrence' that has never before occurred with any of Google Cloud's clients globally. This should not have happened. Google Cloud has identified the events that led to this disruption and taken measures to ensure this does not happen again."

Texas Spot Power Prices Jump Almost 100-Fold On Tight Supply (yahoo.com) 127

ArchieBunker quotes a report from Bloomberg: Texas electricity prices soared almost 100-fold as a high number of power-plant outages raised concerns of a potential evening shortfall. Spot prices at the North Hub, which includes Dallas, jumped to more than $3,000 a megawatt-hour just before 7 p.m. local time, versus about $32 at the same time Tuesday, according to data from the Electric Reliability Council of Texas. This morning, Ercot, as the state's main grid operator is known, issued a "watch" for a potential capacity reserve shortage from about 7-9 p.m., meaning the buffer of spare supplies could fall to low enough levels to call on back-up generation, cancel or delay outages or curb usage.

The conditions are the tightest of the year so far and raises the risk of prices rising to the $5,000 cap -- which they last did on April 16, when Ercot also warned of a potential shortfall. Unusually hot weather in the region has boosted demand for cooling and lowered the efficiency of many power plants. Wind output has also fallen from a day earlier and there are more outages. "Ercot has not called for conservation this evening," it said by email. "The grid is operating under normal conditions at this time."

Is the Era of Stickers In Apple Boxes Coming To an End? (9to5mac.com) 57

Citing a memo distributed to Apple Store employees, 9to5Mac reports that the new iPad Pro and iPad Air lineups will not include Apple stickers in the box -- "a key piece of memorabilia" that dates back as far as 1977's Apple II, notes Ars Technica. While the company says that this is part of its environmental goals to completely remove plastic from its packaging, it begs the question: is the era of stickers in Apple boxes coming to an end? 9to5Mac reports: The M3 MacBook Air that launched in March includes stickers in the box, but Apple Vision Pro (which launched in February) does not. Will the iPhone 16 include stickers in the box? Only time will tell. Ars' Andrew Cunningham writes about the origins of the Apple stickers: Apple has included stickers with its products at least as far back as the Apple II in 1977 when the stickers still said "Apple Computer" on them in the company's then-favored Motter Tektura typeface (I couldn't track down a vintage Apple II unboxing, but I did find some fun photos of Apple enthusiast Dan Budiac opening a sealed-in-box mid-'80s-era Apple IIc, complete with rainbow pack-in stickers). I myself became familiar with them during the height of the iPod in the early to mid-2000s when Apple was still firmly a tech underdog, and people would stick white Apple logo stickers to their cars to show off their non-conformist cred and/or Apple brand loyalty.

As Apple's products became more colorful in the 2010s, the Apple logo stickers would sometimes be color-matched to the device you had just bought, a cute bit of attention to detail that has carried over into present-day MagSafe cables and color-matched iMac keyboards and trackpads.
The report notes that you can still request an Apple sticker at Apple Stores at the time of your purchase; however, Amazon, Best Buy, and other retailers don't appear to have them available.

Renewable Energy Passes 30% of World's Electricity Supply (theguardian.com) 153

Renewable energy accounted for more than 30% of the world's electricity for the first time last year, according to climate thinktank Ember. The Guardian reports: Clean electricity has already helped to slow the growth in fossil fuels by almost two-thirds in the past 10 years, according to the report by climate thinktank Ember. It found that renewables have grown from 19% of electricity in 2000 to more than 30% of global electricity last year. Solar was the main supplier of electricity growth, according to Ember, adding more than twice as much new electricity generation as coal in 2023. It was the fastest-growing source of electricity for the 19th consecutive year, and also became the largest source of new electricity for the second year running, after surpassing wind power.

The first comprehensive review of global electricity data covers 80 countries, which represent 92% of the world's electricity demand, as well as historic data for 215 countries. The surge in clean electricity is expected to power a 2% decrease in global fossil fuel generation in the year ahead, according to Ember. [...] World leaders are aiming to grow renewables to 60% of global electricity by 2030 under an agreement struck at the UN's Cop28 climate change conference in December. This would require countries to triple their current renewable electricity capacity in the next six years, which would almost halve power sector emissions.

Apple Announces M4 With More CPU Cores and AI Focus (arstechnica.com) 66

An anonymous reader quotes a report from Ars Technica: In a major shake-up of its chip roadmap, Apple has announced a new M4 processor for today's iPad Pro refresh, barely six months after releasing the first MacBook Pros with the M3 and not even two months after updating the MacBook Air with the M3. Apple says the M4 includes "up to" four high-performance CPU cores, six high-efficiency cores, and a 10-core GPU. Apple's high-level performance estimates say that the M4 has 50 percent faster CPU performance and four times as much graphics performance. Like the GPU in the M3, the M4 also supports hardware-accelerated ray-tracing to enable more advanced lighting effects in games and other apps. Due partly to its "second-generation" 3 nm manufacturing process, Apple says the M4 can match the performance of the M2 while using just half the power.

As with so much else in the tech industry right now, the M4 also has an AI focus; Apple says it's beefing up the 16-core Neural Engine (Apple's equivalent of the Neural Processing Unit that companies like Qualcomm, Intel, AMD, and Microsoft have been pushing lately). Apple says the M4 runs up to 38 trillion operations per second (TOPS), considerably ahead of Intel's Meteor Lake platform, though a bit short of the 45 TOPS that Qualcomm is promising with the Snapdragon X Elite and Plus series. The M3's Neural Engine is only capable of 18 TOPS, so that's a major step up for Apple's hardware. Apple's chips since 2017 have included some version of the Neural Engine, though to date, those have mostly been used to enhance and categorize photos, perform optical character recognition, enable offline dictation, and do other oddities. But it may be that Apple needs something faster for the kinds of on-device large language model-backed generative AI that it's expected to introduce in iOS and iPadOS 18 at WWDC next month.
A separate report from the Wall Street Journal says Apple is developing a custom chip to run AI software in datacenters. "Apple's server chip will likely be focused on running AI models, also known as inference, rather than in training AI models, where Nvidia is dominant," reports Reuters.

Ten Years Ago Microsoft Bought Nokia's Phone Unit, Then Killed It As a Tax Write-Off (theregister.com) 82

The Register provides a retrospective look at how Microsoft "absorbed the handset division of Nokia" ten years ago, only to kill the unit two years later and write it off as a tax loss. What went wrong? "It was a fatal combination of bad management, a market evolving in ways hidebound people didn't predict, and some really (with a few superb exceptions) terrible products," reports The Register. From the report: Like Nokia, Windows Mobile's popularity peaked in 2007, then started to drop away. The iPhone was the tech item of choice for fashionistas, Blackberry was seen as essential for serious business, and Android -- with Google as its new owner -- was gaining traction. Microsoft by that time had a new CEO in Steve Ballmer, who completely and famously failed to see the shifting sands in the mobile market. He dismissed the iPhone as a threat to what he thought was Windows Mobile's unassailable market position, and was roundly mocked for it. So the scene was set for a mobile standards war, and Steve Ballmer staked his professional pride on winning it. Microsoft recruited Nokia to help out. [...]

Under [Executive VP of Microsoft Stephen Elop's] leadership, a closer working relationship with Microsoft was a given -- but in 2013 Redmond announced it was going the whole hog and buying Nokia's handset business outright for $7.2 billion. The deal was done in April 2014, a decade ago from today. Microsoft also got a ten-year license on Nokia's patents and the option to renew in perpetuity. It also got Elop back, as executive vice president of the Microsoft Devices Group. That meant stepping down as CEO of Nokia, for which he trousered an 18.8 million bonus package -- a payoff the Finnish prime minister at the time called "outrageous." Nokia retained its networking business in Finland. It purchased Siemens' half of the Nokia Siemens Networks joint venture and renamed in Nokia Networks. The Nokia board rolled the dice again on hiring another non-Suomi manager, Rajeev Suri, and this time hit a double D20 in D&D terms.

When Ballmer stepped down from the helm at Microsoft in 2014 -- shortly before the Nokia deal completion -- he left a hot mess to deal with. His plan had been to develop the mobile operating system in conjunction with Windows 10, and Windows Mobile 10 was supposed to be a part of a unified code environment. While Windows 10 on the desktop wasn't a bad operating system, Windows Mobile 10 really was. The promised synergy just didn't happen -- it was power-hungry, clunky, and about as popular as a rattlesnake in a pinata. It was this mess that Satya Nadella faced when he took over the reins. Nadella was never very keen on the phone platform and spent more time in press conferences talking about cricket or the cloud than Microsoft's mobile ambitions. It was clear to all that this really wasn't working. Elop was laid off by Redmond a year later.

It was clear that Windows Mobile wasn't going to work. Android and iOS were drinking Microsoft's milkshake, and Redmond realized the game was up. Microsoft started shedding mobile jobs -- both in Finland and Redmond. While mobile was still publicly touted as the way forward for Microsoft with Ballmer gone, the impetus wasn't there and support for the mobile OS shriveled. In 2015 Microsoft declared it was writing off $7.6 billion on the Phone Hardware division as "goodwill and asset impairment charges" -- $400 million more than it had originally paid for the Finnish firm. Nokia bought European networking giant Alcatel-Lucent in a $16.7 billion deal in 2015. Around the same time, Suri announced a move into tablets, since it had a non-compete agreement with Microsoft on mobiles. Meanwhile a bunch of former Nokia execs who'd fled Elop and Microsoft had started a mobile biz of their own: HMD. It was Finnish, but outsourced production to Foxconn in China, and was planning to make cheapish Android devices. In 2016 Microsoft sold its mobile hardware arm to HMD for an undisclosed -- but probably not large -- sum. Nadella clearly wanted out of the whole business and the Finnish startup concentrated on selling good-enough Android smartphones to Nokia's traditional cheap markets.

Finding Land for US Wind Farms Might Be Easier Than We Thought (msn.com) 81

The Washington Post reports that wind turbines "only take up five percent of the land where they've been built, new research shows." The rest of the space can be used for other purposes, such as agriculture, according to a study published recently in the peer-reviewed journal Environmental Science and Technology. This means developers could fit turbines in places that are often perceived as unsuitable for a wind farm.

The new study highlights that turbines and existing human development, such as agriculture, cannot only share the same area, but also that building wind farms where there are already roads and other infrastructure could help reduce impacts on the land. "Clever siting, use of existing infrastructure, multiple use of landscapes — all these things ... can really contribute to solutions in areas where wind power is acceptable to the local people," said Sarah Jordaan, the study's principal investigator.

Historically, planning studies for wind farms have often assumed that turbines would disturb all the land at the site and leave the area unusable for anything else, said Jordaan, an associate professor in the department of civil engineering at McGill University. The study's findings provide a more accurate accounting of how much land is needed for wind farms, she added.

Lithium-Free Sodium Batteries Exit the Lab, Enter US Production (newatlas.com) 138

Natron Energy, a pioneer in sodium-ion battery technology, has officially commenced mass production of its lithium-free sodium batteries in its Holland, Michigan facility, offering an alternative energy storage solution with benefits such as faster cycling, longer lifespan, and safer usage compared to lithium-ion batteries. New Atlas reports: Not only is sodium somewhere between 500 to 1,000 times more abundant than lithium on the planet we call Earth, sourcing it doesn't necessitate the same type of earth-scarring extraction. Even moving beyond the sodium vs lithium surname comparison, Natron says its sodium-ion batteries are made entirely from abundantly available commodity materials that also include aluminum, iron and manganese. Furthermore, the materials for Natron's sodium-ion chemistry can be procured through a reliable US-based domestic supply chain free from geopolitical disruption. The same cannot be said for common lithium-ion materials like cobalt and nickel.

Sodium-ion tech has received heightened interest in recent years as a more reliable, potentially cheaper energy storage medium. While its energy density lags behind lithium-ion, advantages such as faster cycling, longer lifespan and safer, non-flammable end use have made sodium-ion an attractive alternative, especially for stationary uses like data center and EV charger backup storage. [...] Natron says its batteries charge and discharge at rates 10 times faster than lithium-ion, a level of immediate charge/discharge capability that makes the batteries a prime contender for the ups and downs of backup power storage. Also helping in that use case is an estimated lifespan of 50,000 cycles.

A New Battery Warns Parents if Their Child Has Swallowed It (nytimes.com) 244

A new battery from Energizer comes with "color alert technology" to alert parents if their child has swallowed one. When the coin lithium battery comes into contact with saliva, it activates a blue dye "so parents and caregivers know that medical attention could be required," reports the New York Times. The battery also features more secure packaging and a nontoxic bitter coating. From the report: The new coin lithium battery features more secure packaging, a nontoxic bitter coating to discourage swallowing and "color alert technology" that activates a blue dye when the battery comes into contact with moisture, like saliva, so parents and caregivers know that medical attention could be required. The new battery was announced in a video last week by Energizer and Trista Hamsmith, whose 18-month-old daughter died after swallowing a button battery from a remote control. Ms. Hamsmith founded a nonprofit organization focused on children's safety, successfully advocated for legislation, known as Reese's Law, that requires a secure compartment of the batteries in products that use them as well as stronger warning labels on all packaging, and is now working to make the batteries themselves safer.

Ingested coin or button batteries result in thousands of emergency hospital visits each year, according to the U.S. Consumer Product Safety Commission, which notes that "the consequences of a child swallowing a battery can be immediate, devastating and deadly." "A button cell battery can burn through a child's throat or esophagus in as little as two hours if swallowed," according to the agency. Secure packaging and bitter coatings for batteries have long existed, but "the massive breakthrough here is the color alert technology, which helps give caretakers that indicator that something has happened," Jeff Roth, the global category leader for batteries at Energizer, said in an interview on Wednesday. "The most significant part about this is getting help early in the process," he said. "That's really what the color alert technology allows the family to do."

Dropbox Says Hackers Breached Digital-Signature Product (yahoo.com) 12

An anonymous reader quotes a report from Bloomberg: Dropbox said its digital-signature product, Dropbox Sign, was breached by hackers, who accessed user information including emails, user names and phone numbers. The software company said it became aware of the cyberattack on April 24, sought to limit the incident and reported it to law enforcement and regulatory authorities. "We discovered that the threat actor had accessed data related to all users of Dropbox Sign, such as emails and user names, in addition to general account settings," Dropbox said Wednesday in a regulatory filing. "For subsets of users, the threat actor also accessed phone numbers, hashed passwords, and certain authentication information such as API keys, OAuth tokens, and multi-factor authentication."

Dropbox said there is no evidence hackers obtained user accounts or payment information. The company said it appears the attack was limited to Dropbox Sign and no other products were breached. The company didn't disclose how many customers were affected by the hack. The hack is unlikely to have a material impact on the company's finances, Dropbox said in the filing. The shares declined about 2.5% in extended trading after the cyberattack was disclosed and have fallen 20% this year through the close.

China Launches World's Largest Electric Container Ship (techtimes.com) 94

AmiMoJo shares a report from Tech Times: China has reached a major landmark in green transportation with the launch of the world's largest fully electric container ship. Developed and manufactured by China Ocean Shipping Group (Cosco), the vessel is now operating a regular service route between Shanghai and Nanjing, aiming to reduce emissions significantly along its journey. The Greenwater 01, an all-electric container ship, is positioning itself to be a shipping industry pioneer. Equipped with a main battery exceeding 50,000 kilowatt-hours, the vessel can accommodate additional battery boxes for longer voyages. These battery boxes, each containing 1,600 kilowatt-hours of electricity and similar in size to standard 20-foot containers, provide flexibility in extending the ship's travel range. With 24 battery boxes onboard, the Greenwater 01 can complete a journey consuming 80,000 kilowatt-hours of electricity. This is equivalent to saving 15 tons of fuel compared to a standard container ship, highlighting the efficiency of electric propulsion systems. According to Cosco, the vessel can reduce CO2 emissions by 2,918 tons per year, which is equivalent to taking 2,035 family cars off the road or planting 160,000 trees.

America's Wind Power Production Drops For the First Time In 25 Years (yahoo.com) 110

An anonymous reader quotes a report from Bloomberg: U.S. wind power slipped last year for the first time in a quarter-century due to weaker-than-normal Midwest breezes, underscoring the challenge of integrating volatile renewable energy sources into the grid. Power produced by turbines slipped 2% in 2023, even after developers added 6.2 gigawatts of new capacity, according to a government report Tuesday. The capacity factor for the country's wind fleet -- how much energy it's actually generating versus its maximum possible output -- declined to an eight-year low of 33.5%. Most of that decline was driven by the central US, a region densely dotted with turbines.

Wind is a key component of the effort to cut carbon emissions, but the data highlights the downside of relying on intermittent energy sources tied to the effects of global weather. Last year's low wind speeds came during El Nino, a warming of the equatorial Pacific that tends to weaken trade winds. La Nina, the Pacific cooling pattern that dominated in 2022 and is poised to return later this year, usually has the opposite effect.
The U.S. Energy Information Administration shared the findings in a report published earlier today.

G7 Reaches Deal To Exit From Coal By 2035 148

An anonymous reader quotes a report from Reuters: Energy ministers from the Group of Seven (G7) major democracies reached a deal to shut down their coal-fired power plants in the first half of the 2030s, in a significant step towards the transition away from fossil fuels. "There is a technical agreement, we will seal the final political deal on Tuesday," said Italian energy minister Gilberto Pichetto Fratin, who is chairing the G7 ministerial meeting in Turin. On Tuesday the ministers will issue a final communique detailing the G7 commitments to decarbonize their economies. Pichetto said the ministers were also pondering potential restrictions to Russian imports of liquefied natural gas to Europe which the European Commission is due to propose in the short-term.

The agreement on coal marks a significant step in the direction indicated last year by the COP28 United Nations climate summit to phase out fossil fuels, of which coal is the most polluting. Italy last year produced 4.7% of its total electricity through a handful of coal-fired stations. Rome currently plans to turn off its plants by 2025, except on the island of Sardinia where the deadline is 2028. In Germany and Japan coal has a bigger role, with the share of electricity produced by the fuel higher than 25% of total last year.
"This is another nail in the coffin for coal," said Dave Jones, Ember's Global Insights program director. "The journey to phase out coal power has been long: it's been over seven years since the UK, France, Italy, and Canada committed to phase out coal power, so it's good to see the United States and especially Japan at last be more explicit on their intentions."

"The problem is that whilst coal power has already been falling, gas power has not. G7 nations already promised to 'fully or predominantly' decarbonize their power sectors by 2035, and that would mean phasing out not only coal by 2035 but also gas. Coal might be the dirtiest, but all fossil fuels need to be ultimately phased out."

Motherboard Makers Apparently To Blame For High-end Intel Core i9 CPU Failures (arstechnica.com) 57

An anonymous reader shares a report: Earlier this month, we wrote that some of Intel's recent high-end Core i9 and Core i7 processors had been crashing and exhibiting other weird issues in some games and that Intel was investigating the cause. An Intel statement obtained by Igor's Lab suggests that Intel's investigation is wrapping up, and the company is pointing squarely in the direction of enthusiast motherboard makers that are turning up power limits and disabling safeguards to try to wring a little more performance out of the processors.

"While the root cause has not yet been identified, Intel has observed the majority of reports of this issue are from users with unlocked/overclock capable motherboards," the statement reads. "Intel has observed 600/700 Series chipset boards often set BIOS defaults to disable thermal and power delivery safeguards designed to limit processor exposure to sustained periods of high voltage and frequency."

These are the specific settings that Intel believes are causing problems:
Disabling Current Excursion Protection (CEP)
Enabling the IccMax Unlimited bit
Disabling Thermal Velocity Boost (TVB) and/or Enhanced Thermal Velocity Boost (eTVB)

Additional settings which may increase the risk of system instability:
Disabling C-states
Using Windows Ultimate Performance mode
Increasing PL1 and PL2 beyond Intel recommended limits.

Austria Calls For Rapid Regulation as It Hosts Meeting on 'Killer Robots' (reuters.com) 38

Austria called on Monday for fresh efforts to regulate the use of AI in weapons systems that could create so-called 'killer robots', as it hosted a conference aimed at reviving largely stalled discussions on the issue. From a report: With AI technology advancing rapidly, weapons systems that could kill without human intervention are coming ever closer, posing ethical and legal challenges that most countries say need addressing soon. "We cannot let this moment pass without taking action. Now is the time to agree on international rules and norms to ensure human control," Austrian Foreign Minister Alexander Schallenberg told the meeting of non-governmental and international organisations as well as envoys from 143 countries.

"At least let us make sure that the most profound and far-reaching decision, who lives and who dies, remains in the hands of humans and not of machines," he said in an opening speech to the conference entitled "Humanity at the Crossroads: Autonomous Weapons Systems and the Challenge of Regulation." Years of discussions at the United Nations have produced few tangible results and many participants at the two-day conference in Vienna said the window for action was closing rapidly.

America's First Big-Rig Hydrogen Fuel Station Opens in California (msn.com) 131

Oakland, California is now home to "the first commercial hydrogen fuel station for big-rig trucks in the United States," according to the Los Angeles Times — serving 30 hydrogen fuel-cell trucks.

The newspaper says the facility "could mark the start of a nationwide network for fuel-cell truck refueling. It could also flop." Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. The fuel cells, which drive electric motors to drive the truck, are enormously expensive as well.... The vehicles themselves are expensive too. Both battery electric and hydrogen fuel-cell trucks can cost three times as much or more than a $120,000 diesel truck. Those buying the trucks can qualify for state and federal subsidies to make up most of the upfront costs.
But government regulations may spark some demand: New diesel truck sales will be outlawed in California by 2036. Only zero-tailpipe-emission new trucks will be allowed. Already, zero-emission requirements are in place for trucks that enter ocean ports. And only two technologies are available to achieve that goal: battery electric trucks and hydrogen fuel-cell trucks. "We believe a good portion of those will be hydrogen vehicles," said Matt Miyasato, chief of public policy for hydrogen fuel distributor FirstElement Fuel. FirstElement, through its True Zero brand fueling stations, is the largest hydrogen vehicle fuel distributor in the U.S...

Battery electric is gaining a strong foothold in the medium-sized delivery truck market, but hydrogen could have a leg up for long-haul trucking. While a fuel cell is comparable in size to a diesel engine, a battery big enough for long-haul trucks adds weight and size and cuts down on the total freight load the truck can deliver. And while an electric truck battery can take hours to recharge, the refill time for hydrogen is more comparable to filling up with diesel fuel.
