Apple Chips Can Be Hacked To Leak Secrets From Gmail, ICloud, and More (arstechnica.com) 28

An anonymous reader quotes a report from Ars Technica: Apple-designed chips powering Macs, iPhones, and iPads contain two newly discovered vulnerabilities that leak credit card information, locations, and other sensitive data from the Chrome and Safari browsers as they visit sites such as iCloud Calendar, Google Maps, and Proton Mail. The vulnerabilities, affecting the CPUs in later generations of Apple A- and M-series chip sets, open them to side channel attacks, a class of exploit that infers secrets by measuring manifestations such as timing, sound, and power consumption. Both side channels are the result of the chips' use of speculative execution, a performance optimization that improves speed by predicting the control flow the CPUs should take and following that path, rather than the instruction order in the program. [...]

The researchers published a list of mitigations they believe will address the vulnerabilities allowing both the FLOP and SLAP attacks. They said that Apple officials have indicated privately to them that they plan to release patches. In an email, an Apple representative declined to say if any such plans exist. "We want to thank the researchers for their collaboration as this proof of concept advances our understanding of these types of threats," the spokesperson wrote. "Based on our analysis, we do not believe this issue poses an immediate risk to our users."
FLOP, short for Faulty Load Operation Predictor, exploits a vulnerability in the Load Value Predictor (LVP) found in Apple's A- and M-series chipsets. By inducing the LVP to predict incorrect memory values during speculative execution, attackers can access sensitive information such as location history, email content, calendar events, and credit card details. This attack works on both Safari and Chrome browsers and affects devices including Macs (2022 onward), iPads, and iPhones (September 2021 onward). FLOP requires the victim to interact with an attacker's page while logged into sensitive websites, making it highly dangerous due to its broad data access capabilities.

SLAP, on the other hand, stands for Speculative Load Address Predictor and targets the Load Address Predictor (LAP) in Apple silicon, exploiting its ability to predict memory locations. By forcing LAP to mispredict, attackers can access sensitive data from other browser tabs, such as Gmail content, Amazon purchase details, and Reddit comments. Unlike FLOP, SLAP is limited to Safari and can only read memory strings adjacent to the attacker's own data. It affects the same range of devices as FLOP but is less severe due to its narrower scope and browser-specific nature. SLAP demonstrates how speculative execution can compromise browser process isolation.

US Solar Boom Continues, But It's Offset By Rising Power Use (arstechnica.com) 84

In the first 11 months of 2024, solar energy generation in the US grew by 30%, enabling wind and solar combined to surpass coal for the first time. However, as Ars Technica's John Timmer reports, "U.S. energy demand saw an increase of nearly 3 percent, which is roughly double the amount of additional solar generation." He continues: "Should electric use continue to grow at a similar pace, renewable production will have to continue to grow dramatically for a few years before it can simply cover the added demand." From the report: Another way to look at things is that, between the decline of coal use and added demand, the grid had to generate an additional 136 TW-hr in the first 11 months of 2024. Sixty-three of those were handled by an increase in generation using natural gas; the rest, or slightly more than half, came from emissions-free sources. So, renewable power is now playing a key role in offsetting demand growth. While that's a positive, it also means that renewables are displacing less fossil fuel use than they might.

In addition, some of the growth of small-scale solar won't show up on the grid, since it offset demand locally, and so also reduced some of the demand for fossil fuels. Confusing matters, this number can also include things like community solar, which does end up on the grid; the EIA doesn't break out these numbers. We can expect next year's numbers to also show a large growth in solar production, as the EIA says that the US saw record levels of new solar installations in 2024, with 37 Gigawatts of new capacity. Since some of that came online later in the year, it'll produce considerably more power next year. And, in its latest short-term energy analysis, the EIA expects to see over 20 GW of solar capacity added in each of the next two years. New wind capacity will push that above 30 GW of renewable capacity each of these years.

That growth will, it's expected, more than offset continued growth in demand, although that growth is expected to be somewhat slower than we saw in 2024. It also predicts about 15 GW of coal will be removed from the grid during those two years. So, even without any changes in policy, we're likely to see a very dynamic grid landscape over the next few years. But changes in policy are almost certainly on the way.

Should Big Tech Plug Its Data Centers Directly Into Power Plants? (apnews.com) 86

"Looking for a quick fix for their fast-growing electricity diets, tech giants are increasingly looking to strike deals with power plant owners to plug in directly," reports the Associated Press, "avoiding a potentially longer and more expensive process of hooking into a fraying electric grid that serves everyone else." (It can take up to four years to connect a data center to the grid, one data center trade group says in the article — years longer than it takes to build a new data center.)

But the idea of bypassing the grid is "raising questions over whether diverting power to higher-paying customers will leave enough for others and whether it's fair to excuse big power users from paying for the grid." Front and center is the data center that Amazon's cloud computing subsidiary, Amazon Web Services, is building next to the Susquehanna nuclear plant in eastern Pennsylvania. The arrangement between the plant's owners and AWS — called a "behind the meter" connection — is the first such to come before the Federal Energy Regulatory Commission. For now, FERC has rejected a deal that could eventually send 960 megawatts — about 40% of the plant's capacity — to the data center. That's enough to power more than a half-million homes... [But the FERC's 2-1 rejection "was procedural. Recent comments by commissioners suggest they weren't ready to decide how to regulate such a novel matter without more study."]

In theory, the AWS deal would let Susquehanna sell power for more than they get by selling into the grid... The profit potential is one that other nuclear plant operators, in particular, are embracing after years of financial distress and frustration with how they are paid in the broader electricity markets. Many say they have been forced to compete in some markets against a flood of cheap natural gas as well as state-subsidized solar and wind energy. Power plant owners also say the arrangement benefits the wider public, by bypassing the costly buildout of long power lines and leaving more transmission capacity on the grid for everyone else...

Monitoring Analytics, the market watchdog in the mid-Atlantic grid, wrote in a filing to FERC that the impact would be "extreme" if the Susquehanna-AWS model were extended to all nuclear power plants in the territory. Energy prices would increase significantly and there's no explanation for how rising demand for power will be met even before big power plants drop out of the supply mix, it said.

California's Battery Plant Fire Sparks Call for Investigation, New Regulations (yahoo.com) 60

Earlier this month a major fire erupted at a California battery plant. But several factors contributed to its rapid spread, the fire district's chief told the Los Angeles Times: A fire suppression system that is part of every battery rack at the plant failed and led to a chain reaction of batteries catching on fire, he said at a news conference last week. Then, a broken camera system in the plant and superheated gases made it challenging for firefighters to intervene. Once the fire began spreading, firefighters were not able to use water, because doing so can trigger a violent chemical reaction in lithium-ion batteries, potentially causing more to ignite or explode.
The county's Board of Supervisors has now requested that the plant remain offline until an investigation is completed. A county supervisor told the newspaper "What we're doing with this technology is way ahead of government regulations and ahead of the industry's ability to control it."

And plans for a new battery storage site nearby are now being questioned, with an online petition to halt all new battery-storage facilities in the county drawing over 3,200 signatures. The fire earlier this month was the fourth at Moss Landing since 2019, and the third at buildings owned by Texas-based Vistra Energy... Already, the fire has prompted calls for additional safety regulations around battery storage, and more local control over where storage sites are located...

California Assemblymember Dawn Addis (D-Morro Bay) has introduced Assembly Bill 303 — the Battery Energy Safety & Accountability Act — which would require local engagement in the permitting process for battery or energy storage facilities, and establish a buffer to keep such sites a set distance away from sensitive areas like schools, hospitals and natural habitats... Gov. Gavin Newsom, a fierce advocate of clean energy, agrees an investigation is needed to determine the fire's cause and supports taking steps to make Moss Landing and similar facilities safer, his spokesperson Daniel Villaseñor said in a statement. Addis and two other state legislators sent a letter to the California Public Utilities Commission Thursday requesting an investigation.

"The Moss Landing facility has represented a pivotal piece of our state's energy future, however this disastrous fire has undermined the public's trust in utility scale lithium-ion battery energy storage systems," states the letter. "If we are to ensure California moves its climate and energy goals forward, we must demonstrate a steadfast commitment to safety..."

initial testing from the U.S. Environmental Protection Agency ruled that the levels of toxic gases released by the batteries, including hydrogen fluoride, did not pose a threat to public health during the fire. [The EPA says their monitoring "showed concentrations of particulate matter to be consistent with the air quality index throughout the Monterey Bay and San Francisco Bay regions, with no measurements exceeding the moderate air quality level... In addition to EPA's monitoring, Vistra Energy brought in a third-party environmental consultant with air monitoring expertise, right after the fire started"]

Still, many residents remain on edge about potential long-term impacts on the nearby communities of Watsonville, Castroville, Salinas and the ecologically sensitive Elkhorn Slough estuary.

Europe Made More Electricity from Solar Than Coal In 2024 (theguardian.com) 75

Long-time Slashdot reader AmiMoJo shared this report from the Guardian: More electricity was made from sunshine than coal in the EU last year, a report has found, in what analysts called a "milestone" for the clean energy transition. Solar panels generated 11% of the EU's electricity in 2024, while coal-burning power plants generated 10%, according to data from climate thinktank Ember...

Coal-burning in the EU power sector peaked in 2003 and has fallen by 68% since then. At the same time, clean sources of electricity have boomed. Wind and solar energy rose to 29% of EU electricity generation in 2024, while hydropower and nuclear energy continued to rebound from the 2022 lows...

The report found the share of coal fell in 16 of the 17 countries that still used it in 2024. It said the fuel has become "marginal or absent" in most systems. Germany and Poland, the two countries that burn most of the EU's coal, were among those where there was a shift to cleaner sources of energy. The share of coal in Germany's electricity grid fell 17% year-on-year, while in Poland it dropped8%, the report found.

Fossil gas also fell for the fifth year in a row, declining in 14 of the 26 countries, according to the article, and now accounting for just 16% of the electricity mix.

"The findings come despite a small increase in electricity demand after two years of steep decline brought on by Russia's full-scale invasion of Ukraine."

Could New Linux Code Cut Data Center Energy Use By 30%? (datacenterdynamics.com) 65

Two computer scientists at the University of Waterloo in Canada believe changing 30 lines of code in Linux "could cut energy use at some data centers by up to 30 percent," according to the site Data Centre Dynamics.

It's the code that processes packets of network traffic, and Linux "is the most widely used OS for data center servers," according to the article: The team tested their solution's effectiveness and submitted it to Linux for consideration, and the code was published this month as part of Linux's newest kernel, release version 6.13. "All these big companies — Amazon, Google, Meta — use Linux in some capacity, but they're very picky about how they decide to use it," said Martin Karsten [professor of Computer Science in the Waterloo's Math Faculty]. "If they choose to 'switch on' our method in their data centers, it could save gigawatt hours of energy worldwide. Almost every single service request that happens on the Internet could be positively affected by this."

The University of Waterloo is building a green computer server room as part of its new mathematics building, and Karsten believes sustainability research must be a priority for computer scientists. "We all have a part to play in building a greener future," he said. The Linux Foundation, which oversees the development of the Linux OS, is a founder member of the Green Software Foundation, an organization set up to look at ways of developing "green software" — code that reduces energy consumption.

Karsten "teamed up with Joe Damato, distinguished engineer at Fastly" to develop the 30 lines of code, according to an announcement from the university. "The Linux kernel code addition developed by Karsten and Damato was based on research published in ACM SIGMETRICS Performance Evaluation Review" (by Karsten and grad student Peter Cai).

Their paper "reviews the performance characteristics of network stack processing for communication-heavy server applications," devising an "indirect methodology" to "identify and quantify the direct and indirect costs of asynchronous hardware interrupt requests (IRQ) as a major source of overhead...

"Based on these findings, a small modification of a vanilla Linux system is devised that improves the efficiency and performance of traditional kernel-based networking significantly, resulting in up to 45% increased throughput..."

Heat Pumps Are Now Outselling Gas Furnaces In America (cleantechnica.com) 155

CleanTechnicareports that last year Americans "bought 37% more air source heat pumps than the next most popular heating appliance — gas furnaces."

And Americans bought 21% more heat pumps than they did in 2023. Canary Media is quick to point out that in many homes, more than one heat pump is required, so that data should be interpreted with that in mind. Typically, a home uses only one furnace. Nevertheless, the trend for heat pumps is up. Russell Unger, the head of decarbonizing buildings at RMI, said, "There's just been this long term, consistent trend."

It's easy to understand why heat pumps are gaining in popularity. In addition to providing heated air in the winter and cool air in the summer, they are far more efficient than conventional heat sources — delivering three to four times more heat per dollar spent than oil- or gas-fired heating equipment or old fashioned electric baseboard heat. They also create far less carbon pollution. How much less depends on the source of electricity in the local area,

EV Maker Canoo 'Goes Belly-Up After Moving to Texas' (sfgate.com) 68

2021: "Automotive Startup Canoo Debuts a Snub-Nosed Electric Pickup"
2025: Canoo "Goes Belly-Up After Moving to Texas"

"Its production volumes paled in comparison to Canoo's rate of cash burn, which was substantial, with net losses in 2023 totaling just over $300 million..." reports AutoWeek. "It was able to deliver small batches of vans to a few customers, but apparently remained distant from anything approaching volume production."

"Back in 2020, electric vehicle maker Canoo snagged a $2.4 billion valuation before it had shipped a single car," remembers SFGate. "Now, just months after yanking its headquarters from Los Angeles County to Texas, the company has gone belly-up." In its four-year span as a public company, Canoo battled investor lawsuits, Securities and Exchange Commission charges, executive departures and a mixed reception of its cars. Auto tech blogger Steven Symes recently likened Canoo's cargo-style van to an "eraser on wheels."
"Canoo is the latest EV startup to go bankrupt after merging with a special purpose acquisition company (SPAC) as a shortcut to going public," notes TechCrunch. "Electric Last Mile Solutions was the first in June 2022. But since then, Fisker, Lordstown Motors, Proterra, Lion Electric, and Arrival all filed for different levels of bankruptcy protection in their various home countries." In the years since it went public, [Canoo] made a small number of its bubbly electric vans and handed them over to partners — some paying — willing to trial the vehicles. The U.S. Postal Service, Department of Defense, and NASA all have or had Canoo vehicles.

Bambu Labs' 3D Printer 'Authorization' Update Beta Sparks Concerns (theverge.com) 47

Slashdot reader jenningsthecat writes: 3D printer manufacturer Bambu Labs has faced a storm of controversy and protest after releasing a security update which many users claim is the first step in moving towards an HP-style subscription model.
Bambu Labs responded that there's misinformation circulating online, adding "we acknowledge that our communication might have contributed to the confusion." Bambu Labs spokesperson Nadia Yaakoubi did "damage control", answering questions from the Verge: Q: Will Bambu publicly commit to never requiring a subscription in order to control its printers and print from them over a home network?

A: For our current product line, yes. We will never require a subscription to control or print from our printers over a home network...

Q: Will Bambu publicly commit to never putting any existing printer functionality behind a subscription?

Yes...

Bambu's site adds that the security update "is beta testing, not a forced update. The choice is yours. You can participate in the beta program to help us refine these features, or continue using your current firmware."

Hackaday notes another wrinkle: This follows the original announcement which had the 3D printer community up in arms, and quickly saw the new tool that's supposed to provide safe and secure communications with Bambu Lab printers ripped apart to extract the security certificate and private key... As the flaming wreck that's Bambu Lab's PR efforts keeps hurtling down the highway of public opinion, we'd be remiss to not point out that with the security certificate and private key being easily obtainable from the Bambu Connect Electron app, there is absolutely no point to any of what Bambu Lab is doing.
The Verge asked Bambu Labs about that too: Q: Does the private key leaking change any of your plans?

No, this doesn't change our plans, and we've taken immediate action.

Bambu Labs had said their security update would "ensure only authorized access and operations are permitted," remembers Ars Technica. "This would, Bambu suggested, mitigate risks of 'remote hacks or printer exposure issues' and lower the risk of 'abnormal traffic or attacks.'" This was necessary, Bambu wrote, because of increases in requests made to its cloud services "through unofficial channels," targeted DDOS attacks, and "peaks of up to 30 million unauthorized requests per day" (link added by Bambu).
But Ars Technica also found some skepticism online: Repair advocate Louis Rossmann, noting Bambu's altered original blog post, uploaded a video soon after, "Bambu's Gaslighting Masterclass: Denying their own documented restrictions"... suggesting that the company was asking buyers to trust that Bambu wouldn't enact restrictive policies it otherwise wrote into its user agreements.
And Ars Technica also cites another skeptical response from a video posted by open source hardware hacker and YouTube creator Jeff Geerling: "Every IoT device has these problems, and there are better ways to secure things than by locking out access, or making it harder to access, or requiring their cloud to be integrated."

America Lags on Renewable Energy. Blame Regulations and Grid Connection Issues (msn.com) 127

"For years, renewable energy proponents have hoped to build a U.S. electric grid powered by wind, solar, geothermal and — to a lesser extent — nuclear power..." writes the Washington Post. In America's power markets "the economics of clean energy are strong," with renewable energy cheaper than fossil fuel plants in many jurisdictions.

But the Post spoke to the "electricity modeling" director at nonpartisan clean energy think tank Energy Innovation, who offered this assessment. "The technology is ready, and the financial services are ready — but the question nobody really put enough thought into was, could the government keep up? And at the moment, the answer is no." [R]enewable developers say that the new technologies are stymied by complicated local and federal regulations, a long wait to connect to the electricity grid, and community opposition... "The U.S. offshore wind business is at a very nascent stage versus Europe or China," Rob Barnett, a senior analyst at Bloomberg Intelligence, said in an email. "With the new permitting pause, it's doubtful much progress for this emerging industry will be made...." After the Inflation Reduction Act passed, Rhodium Group — an independent clean energy research firm — estimated that between 2023 and 2025, on average, the country would add between 36 and 46 gigawatts of clean electricity to the grid every year. Late last year, however, the group found that the country only installed around 27 gigawatts in 2023. The U.S.'s renewable growth is now expected to fall on the low end of that range — or miss it entirely.

"It actually is really hard to build a lot of this stuff fast," said Trevor Houser, partner in climate and energy at Rhodium Group. As a result, Rhodium found, the country only cut carbon emissions by 0.2 percent in 2024... A significant amount of this lag has come from wind power, where problems with supply chains and getting permits and approval to build has put a damper on development. But solar construction is also on the low end of what experts were expecting...

Developers point to lags in the interconnection queue — a system that gives new solar, wind or fossil fuel projects permission to connect to the larger electricity grid. According to a report from Lawrence Berkeley National Laboratory, it can now take nearly 3 years for a project to get through the queue. The grid operator that covers the Mid-Atlantic and parts of the Midwest, PJM, had over 3,300 projects in its queue at the end of 2023. The vast majority of these applications are for renewables — more than the entire number of active wind farms in the nation... There are possible solutions. Some developers hope to reuse old fossil fuel sites, like coal plants, that are already connected to the grid — bypassing the long queue entirely. The Federal Energy Regulatory Commission has instated new rules to make it easier to build transmission lines.

Part of the problem is that wind and solar facilities "sometimes need to be built hundreds or even thousands of miles away" — requiring long transmission lines. Sandhya Ganapathy, CEO of EDP Renewables North America, tells the Post that in America, "The grid that we have was never designed to handle this kind of load." And yet last year just 255 miles of new transmission line were built in the U.S., according to the American Clean Power Association. And Ganapathy also complains that approval for a new renewable energy project takes "anywhere between six to eight years" — which makes developers hesitant to build. "Why are we taking a big risk of a massive investment if I will not be able to sell the electrons?"

The end result? The Washington Post writes that "Experts once hoped that by the end of the decade the United States could generate up to 80 percent of its power with clean power... Now, some wonder if the country will be able to reach even 60 percent."

Researchers Say New Attack Could Take Down the European Power Grid (arstechnica.com) 33

An anonymous reader quotes a report from Ars Technica: Late last month, researchers revealed a finding that's likely to shock some people and confirm the low expectations of others: Renewable energy facilities throughout Central Europe use unencrypted radio signals to receive commands to feed or ditch power into or from the grid that serves some 450 million people throughout the continent. Fabian Braunlein and Luca Melette stumbled on their discovery largely by accident while working on what they thought would be a much different sort of hacking project. After observing a radio receiver on the streetlight poles throughout Berlin, they got to wondering: Would it be possible for someone with a central transmitter to control them en masse, and if so, could they create a city-wide light installation along the lines of Project Blinkenlights?

The first Project Blinkenlights iteration occurred in 2001 in Berlin, when the lights inside a large building were synchronized to turn on and off to give the appearance of a giant, low-resolution monochrome computer screen. The researchers, who presented their work last month at the 38th Chaos Communication Congress in Hamburg, Germany, wondered if they could control streetlights in Berlin to create a city-wide version, though they acknowledged it would likely be viewable only from high altitudes. They didn't know then, but their project was about to undergo a major transformation.

After an extensive and painstaking reverse-engineering process that took about a year, Braunlein and Melette learned that they could indeed control the streetlights simply by replaying legitimate messages they observed being sent over the air previously. They then learned something more surprising — the very same system for controlling Berlin's lights was used throughout Central Europe to control other regional infrastructure, including switches that regulate the amount of power renewable electric generation facilities feed into the grid. Collectively, the facilities could generate as much as 40 gigawatts in Germany alone, the researchers estimate. In addition, they estimate that in Germany, 20 GW of loads such as heat pumps and wall boxes are controlled via those receivers. That adds up to 60 GW that might be controllable through radio signals anyone can send.

When Braunlein and Melette realized how much power was controlled, they wondered how much damage might result from rogue messages sent simultaneously to multiple power facilities in strategically designed sequences and times of day. By their calculation, an optimally crafted series of messages sent under certain conditions would be enough to bring down the entire European grid. [...]
The grid security experts Ars talked to for this story said they're doubtful of the assessment. "A sudden deficit of 60 GW will definitely lead to a brownout because 60 GW is far more than [the] reserves available," said Albert Moser, a RWTH Aachen professor with expertise in power grids. "A sudden deficit of 60 GW could even lead to a blackout due to the very steep fall of frequency that likely cannot be handled fast enough by underfrequency relays (load shedding)." He wasn't able to confirm that 60 GW of generation/load is controlled by radio signals or that security measures for Radio Ripple Control are insufficient.

Jan Hoff, a grid security expert, was also doubtful there'd be enough electricity dropped quickly enough to cause a brownout. "He likened the grid to the roly-poly toys from the 1970s, which were built to be knocked around but not fall over," said Ars.

Charming Science reports: China's "artificial sun," officially known as the Experimental Advanced Superconducting Tokamak (EAST), has achieved a groundbreaking milestone in fusion energy research. According to the Chinese Academy of Sciences (CAS), EAST recently sustained high-confinement plasma operation for an unprecedented 1,066 seconds, shattering the previous world record of 403 seconds, also set by EAST in 2023. [...] The 1,000-second mark is considered a critical threshold in fusion research. Sustaining plasma for such extended durations is essential for demonstrating the feasibility of operating fusion reactors. This breakthrough, accomplished by the Institute of Plasma Physics under the CAS, signifies a major leap towards realizing the potential of fusion energy. [...] The success of EAST's recent experiment can be attributed to several key advancements. Researchers have made significant strides in improving the stability of the heating system, enhancing the accuracy of the control system, and refining the precision of the diagnostic systems.

Dumb New Electrical Code Could Doom Most Common EV Charging (motortrend.com) 226

Longtime Slashdot reader schwit1 shares a report from MotorTrend: A coming ground-fault circuit-interrupter revision could make slow-charging your car nearly impossible. The National Fire Protection Agency (NFPA) publishes a new National Electric Code every three years, and we almost never notice or care. But the next one, NFPA 70 2026, has the Society of Automotive Engineers (SAE) electric-vehicle charging subcommittee, OEMs, and companies in the EV Supply Equipment (EVSE, or charger) biz mightily concerned. That's because it proposes to require the same exact ground-fault circuit-interrupter protection that makes you push that little button on your bathroom outlet every time the curling iron won't heat up. Only now, that reset button will often be down in an electric panel, maybe locked in a room where you can't reset it. If EV drivers can't reliably plug in and expect their cars to charge overnight at home or while at work, those cars will become far less practical. [...]

The national code doesn't care what you're plugging in, but vehicle chargers deserve their own carve-out. That's because no current ever flows until the charger has verified a solid ground connection from car to charger and from charger to electrical panel. They also include their own GFPE (Ground Fault Protection of Equipment), which is intended to protect equipment and is permitted to trip at values larger than 5mA, often in the 15-20mA range. That's why this new code REALLY needs to set a higher supply-side cutout (like what is allowed for marine vehicle shore power, which is up to 30mA). Because even if the Special Purpose GFCI with its 15-20mA trip level were allowed, it would be a 50/50 chance that any fault would trip the electrical-supply breaker or the device's internal breaker. But while the device is programmed to automatically reset and try again, the panel requires a manual reset. There is one EV-charger carve-out: Bi-directional chargers are exempt.

This problematic application of 5 mA trip to most 240-volt equipment was added into this regulation late, during a second draft, and now the only way to head it off is for interested parties (SAE, OEMs, and EVSE manufacturers) to register their notice of motion in February for consideration in March. This isn't a government regulation, so it's utterly unaffected by the change in federal administration. These are functionary folks with minimal experience of EV charging, so the arguments must aim to convince the NFPA that implementing this code as is could grossly embarrass the Agency. (Understanding that any such embarrassment will only arise after buildings and projects are completed under the new code.)

Bill Gates' TerraPower Signs Agreement For Nuclear To Power Data Centers 42

An anonymous reader quotes a report from The Verge: TerraPower, a nuclear energy startup founded by Bill Gates, struck a deal this week with one of the largest data center developers in the US to deploy advanced nuclear reactors. TerraPower and Sabey Data Centers (SDC) are working together on a plan to run existing and future facilities on nuclear energy from small reactors. A memorandum of understanding signed by the two companies establishes a "strategic collaboration" that'll initially look into the potential for new nuclear power plants in Texas and the Rocky Mountain region that would power SDC's data centers. [...]

There's still a long road ahead before that can become a reality. The technology TerraPower and similar nuclear energy startups are developing still have to make it through regulatory hurdles and prove that they can be commercially viable. Compared to older, larger nuclear power plants, the next generation of reactors are supposed to be smaller and easier to site. Nuclear energy is seen as an alternative to fossil fuels that are causing climate change. But it still faces opposition from some advocates concerned about the impact of uranium mining and storing radioactive waste near communities. TerraPower's reactor design for this collaboration, Natrium, is the only advanced technology of its kind with a construction permit application for a commercial reactor pending with the U.S. Nuclear Regulatory Commission, according to the company. The company just broke ground on a demonstration project in Wyoming last year, and expects it to come online in 2030.

Intel Pitches Modular PC Designs To Make Repairs Less Painful (theregister.com) 62

Intel is advocating for modular PC designs to improve repairability, reduce e-waste, and align with the right-to-repair movement. A trio of executives makes their case for such designs in a recent blog post. The Register reports: Intel's approach to the problem is to draft three proposals targeting different market segments, saying that a one-size-fits-all approach would not be able to address the nuanced demands of these varied segments. Those three segments comprise "Premium Modular PC" (actually a laptop design); "Entry/Mainstream Modular PC" (another laptop); and "Desktop Modular PC."

The first envisages a three-board system, comprising a core motherboard plus universal left and right I/O boards, the latter engineered to be common across fan-less Thin & Light designs with a 10W power envelope, and premium fanned designs for up to 20W or 30W. The Entry/Mainstream Modular PC is similar, with a core motherboard and left and right I/O boards, although in this segment, Intel says these can be redesigned to allow multiple SKUs of the design. The circuit boards are also cost-optimized here to cater to the mainstream segment, it says.

The Desktop Modular PC design appears from Intel's diagram to use a midplane that has the Platform Controller Hub (PCH) silicon, with other modules connecting to this. These include CPU, memory, and GPU modules, removable using slide rails, along with hot-swappable storage, all designed to fit inside a 5 liter desktop chassis. Intel also said it is introducing subsystem-level replaceable modules. In practice, this means something like a Type-C connector on a flexible printed circuit (FPC) or an M.2 circuit board. The idea is that the module can easily be swapped out if the port or connector is damaged.

Solar-Charging Backpacks Are Helping Children To Read After Dark (cnn.com) 30

A Tanzanian entrepreneur is transforming cement bags into solar-powered backpacks, helping students study after dark in areas without electricity. Innocent James's company, Soma Bags, sold 36,000 solar backpacks across Africa last year, with prices ranging from 12,000 to 22,500 Tanzanian shillings ($4-8), according to CNN. The innovation comes as 600 million Africans lack electricity access. In Tanzania, fewer than half of mainland households have power, forcing families to rely on expensive kerosene lamps.

The backpacks, manufactured in James's Bulale factory employing 65 staff, feature flexible solar panels that charge during students' walks to school. One day of sunlight provides six to eight hours of reading light, making them more cost-effective than kerosene lamps commonly used in Tanzania, where fewer than half of mainland households have electricity access.

Samsung's Galaxy S25 Phones Once Again Lean Heavily on AI 25

At Galaxy Unpacked today in San Jose, California, Samsung unveiled the new Galaxy S25 series of flagship smartphones loaded with AI capabilities and LLMs. "Currently, the Galaxy S25 range is comprised of the Galaxy S25 ($800), Galaxy S25+ ($1,000), and Galaxy S25 Ultra ($1,300)," reports Wired. "The phones are available for preorder today and will officially go on sale February 7." Since the hardware is relatively unchanged from last year's Galaxy S24 series, here's what Wired has to say about the new AI smarts: The Galaxy S25 is a tale of two AIs: Gemini and Bixby. Yes, while Google's Gemini AI assistant sits at the forefront -- it can finally be triggered through a long press of the power button-- Samsung is bringing its original Bixby voice assistant out from the shadows. Bixby has been enhanced with large language models but is still designed to handle phone functions, like changing device settings. Gemini is meant to be used for general web queries and more complex actions. You can even have two hot words, one for each assistant. I foresee all of this being confusing [...].

The highlight AI feature debuting on the Galaxy S25 series is "cross-app experiences." These are tasks you can ask Gemini to perform, even if the task requires multiple apps. For example, you can ask for the schedule of this season's Arsenal matches and then add it to your calendar; Gemini will then search and add every Arsenal FC game in the season to your schedule. Or you can ask it to find pet-friendly vegan restaurants nearby and text the list to a friend. It even works with images too -- snap a pic of your fridge and ask Gemini to find you a recipe based on the available ingredients. These cross-app experiences work with Google apps, Samsung's Galaxy apps, and select third-party apps, like WhatsApp and Spotify.

All these AI features have culminated in a new app: Now Brief. Samsung calls this proactive assistance (remember Google's Now on Tap?) where a morning brief arrives with the weather, upcoming calendar events, stock details, news articles, and suggestions to trigger routines. There's also an evening brief with a summary of the day's events with photos. Since the feature can plug into email, it'll send reminders about expiring coupons and upcoming travel tickets. Samsung claims it can even suggest changing an 8:45 am alarm even earlier if it sees a 9 am meeting on the schedule. On the lock screen, a "Now Bar" widget persists at the bottom, much like Apple's Live Activities. It'll offer quick access to the Now Brief app, but it will also show updates for favorite sports teams, along with glanceable directions from Google Maps.

The rest of the AI features are playing a bit of catch-up to Apple and Google's Pixel phones. There's Drawing Assist, a generative AI tool to craft new images in different art styles based on sketches or text prompts. AI Select works with the S Pen stylus on the S25 Ultra and understands what is selected -- for example, if a video is selected, it will suggest turning it into a GIF. Audio Eraser is an editing tool to cut out background noise in videos post-capture, canceling out the sound of a crowd's chatter or an ambulance's siren. Finally, Samsung's Generative Edit feature, which lets you erase unwanted objects in images, now works locally on the device and is much more accurate and faster.

South Carolina To Reboot Giant Nuclear Project to Meet AI Demand (msn.com) 67

Santee Cooper, the big power provider in South Carolina, has tapped financial advisers to look for buyers that can restart construction on a pair of nuclear reactors that were mothballed years ago. From a report: The state-owned utility is betting interest will be strong, with tech giants such as Amazon.com and Microsoft in need of clean energy to fuel data centers for artificial-intelligence capabilities. The details Santee Cooper announced Wednesday it is seeking proposals for buyers to complete the project at South Carolina's sprawling V.C. Summer Nuclear Station, confirming an earlier report from The Wall Street Journal.

The utility is working with bankers at Centerview Partners, which will accept proposals until May 5. Santee Cooper will likely look to tap a consortium that could include a construction firm, a tech company that will use the power and an additional partner for capital, according to people familiar with the matter. It is also looking for another power company partner because it doesn't plan to own or operate the units once they are up and running.

China To Host World's First Human-Robot Marathon (scmp.com) 19

Beijing will host the world's first human-robot half-marathon in April, with dozens of humanoid robots competing alongside 12,000 human runners in the capital's Daxing district. The robots, from more than 20 companies, must be between 0.5 and 2 meters tall, bipedal, and capable of walking or running without wheels, according to local authorities. Both remote-controlled and autonomous robots can participate, with battery changes permitted during the 21km (13 miles) race.
