Longtime Slashdot reader AmiMoJo shares a report from the BBC: Banning phones in schools is not linked to pupils getting higher grades or having better mental wellbeing, the first study of its kind suggests. Students' sleep, classroom behavior, exercise or how long they spend on their phones overall also seems to be no different for schools with phone bans and schools without, the academics found. But they did find that spending longer on smartphones and social media in general was linked with worse results for all of those measures.

The first study in the world to look at school phone rules alongside measures of pupil health and education feeds into a fierce debate that has played out in homes and schools in recent years. [...] The University of Birmingham's findings, peer-reviewed and published by the Lancet's journal for European health policy, compared 1,227 students and the rules their 30 different secondary schools had for smartphone use at break and lunchtimes. The schools were chosen from a sample of 1,341 mainstream state schools in England.

The paper says schools restricting smartphone use did not seem to be seeing their intended improvements on health, wellbeing and focus in lessons. However, the research did find a link between more time on phones and social media, and worse mental wellbeing and mental health, less physical activity, poorer sleep, lower grades and more disruptive classroom behavior. The study used the internationally recognized Warwick-Edinburgh Mental Wellbeing Scales to determine participants' wellbeing. It also looked at students' anxiety and depression levels. Dr Victoria Goodyear, the study's lead author, told the BBC the findings were not "against" smartphone bans in schools, but "what we're suggesting is that those bans in isolation are not enough to tackle the negative impacts."

She said the "focus" now needed to be on reducing how much time students spent on their phones, adding: "We need to do more than just ban phones in schools."

Software developer and prolific blogger Herman Ounapuu, writing in a blog post: I liked Ubuntu. For a very long time, it was the sensible default option. Around 2016, I used the Ubuntu GNOME flavor, and after they ditched the Unity desktop environment, GNOME became the default option.

I was really happy with it, both for work and personal computing needs. Estonian ID card software was also officially supported on Ubuntu, which made Ubuntu a good choice for family members.

But then something changed. Ounapuu recounts how Ubuntu's bi-annual long-term support releases consistently broke functionality, from minor interface glitches to catastrophic system failures that left computers unresponsive. His breaking point came after multiple problematic upgrades affecting family members' computers, including one that rendered a laptop completely unusable during an upgrade from Ubuntu 20.04 to 22.04. Another incident left a relative's system with broken Firefox shortcuts and duplicate status bar icons after updating Lubuntu 18.04.

Canonical's aggressive push of Snap packages has drawn particular criticism. The forced migration of system components from traditional Debian packages to Snaps resulted in compatibility issues, broken desktop shortcuts, and government ID card authentication failures. In one instance, he writes, a Snap-related bug in the GNOME desktop environment severely disrupted workplace productivity, requiring multiple system restarts to resolve. The author has since switched to Fedora, praising its implementation of Flatpak as a superior alternative to Snaps.

Temperatures at the north pole soared more than 20C above average on Sunday, crossing the threshold for ice to melt. From a report: Temperatures north of Svalbard in Norway had already risen to 18C hotter than the 1991-2020 average on Saturday, according to models from weather agencies in Europe and the US, with actual temperatures close to ice's melting point of 0C.

By Sunday, the temperature anomaly had risen to more than 20C. "This was a very extreme winter warming event," said Mika Rantanen, a scientist at the Finnish Meteorological Institute. "Probably not the most extreme ever observed, but still at the upper edge of what can happen in the Arctic." Burning fossil fuels has heated the planet by about 1.3C since preindustrial times, but the poles are warming much faster as reflective sea ice melts. The increase in average temperatures has driven an increase in fiercely hot summers and unsettlingly mild winters.

An anonymous reader quotes a report from The Guardian: The pace of global heating has been significantly underestimated, according to renowned climate scientist Prof James Hansen, who said the international 2C target is "dead." A new analysis by Hansen and colleagues concludes that both the impact of recent cuts in sun-blocking shipping pollution, which has raised temperatures, and the sensitivity of the climate to increasing fossil fuels emissions are greater than thought. The group's results are at the high end of estimates from mainstream climate science but cannot be ruled out, independent experts said. If correct, they mean even worse extreme weather will come sooner and there is a greater risk of passing global tipping points, such as the collapse of the critical Atlantic ocean currents.

Hansen, at Columbia University in the US, sounded the alarm to the general public about climate breakdown in testimony he gave to a UN congressional committee in 1988. "The Intergovernmental Panel on Climate Change (IPPC) defined a scenario which gives a 50% chance to keep warming under 2C -- that scenario is now impossible," he said. "The 2C target is dead, because the global energy use is rising, and it will continue to rise." The new analysis said global heating is likely to reach 2C by 2045, unless solar geoengineering is deployed. [...] In the new study, published in the journal Environment: Science and Policy for Sustainable Development, Hansen's team said: "Failure to be realistic in climate assessment and failure to call out the fecklessness of current policies to stem global warming is not helpful to young people."

[...] Hansen said the point of no return could be avoided, based on the growing conviction of young people that they should follow the science. He called for a carbon fee and dividend policy, where all fossil fuels are taxed and the revenue returned to the public. "The basic problem is that the waste products of fossil fuels are still dumped in the air free of charge," he said. He also backed the rapid development of nuclear power. Hansen also supported research on cooling the Earth using controversial geoengineering techniques to block sunlight, which he prefers to call "purposeful global cooling." He said: "We do not recommend implementing climate interventions, but we suggest that young people not be prohibited from having knowledge of the potential and limitations of purposeful global cooling in their toolbox." Political change is needed to achieve all these measures, Hansen said: "Special interests have assumed far too much power in our political systems. In democratic countries the power should be with the voter, not with the people who have the money. That requires fixing some of our democracies, including the US."

OpenAI is partnering with the California State University (CSU) system to bring ChatGPT Edu to the 23-campus community of 500,000 students, calling it the "largest implementation of ChatGPT by any single organization or company anywhere in the world." Fortune reports: As part of ChatGPT Edu, members of the CSU community will get special access to ChatGPT-4o and advanced research and analysis capabilities. The partnership allows schools to create customizable AI chatbots for any project, like a campus IT help desk bot, financial aid assistant, chemistry tutor, or orientation buddy. CSU also plans to introduce free AI skills training for its students, faculty, and staff as well as connect students with AI-related apprenticeship programs. CSU joins a number of other schools with ChatGPT Edu partnerships, including Arizona State University (AS), The University of Texas, Austin, University of Oxford, Columbia University, and the Wharton School at the University of Pennsylvania.

An anonymous reader writes: Low quality books that appear to be AI generated are making their way into public libraries via their digital catalogs, forcing librarians who are already understaffed to either sort through a functionally infinite number of books to determine what is written by humans and what is generated by AI, or to spend taxpayer dollars to provide patrons with information they don't realize is AI-generated.

Public libraries primarily use two companies to manage and lend ebooks: Hoopla and OverDrive, the latter of which people may know from its borrowing app, Libby. Both companies have a variety of payment options for libraries, but generally libraries get access to the companies' catalog of books and pay for customers to be able to borrow that book, with different books having different licenses and prices. A key difference is that with OverDrive, librarians can pick and choose which books in OverDrive's catalog they want to give their customers the option of borrowing. With Hoopla, librarians have to opt into Hoopla's entire catalog, then pay for whatever their customers choose to borrow from that catalog. The only way librarians can limit what Hoopla books their customers can borrow is by setting a limit on the price of books. For example, a library can use Hoopla but make it so their customers can only borrow books that cost the library $5 per use.

On one hand, Hoopla's gigantic catalog, which includes ebooks, audio books, and movies, is a selling point because it gives librarians access to more for cheaper price. On the other hand, making librarians buy into the entire catalog means that a customer looking for a book about how to diet for a healthier liver might end up borrowing Fatty Liver Diet Cookbook: 2000 Days of Simple and Flavorful Recipes for a Revitalized Liver. The book was authored by Magda Tangy, who has no online footprint, and who has an AI-generated profile picture on Amazon, where her books are also for sale. Note the earring that is only on one ear and seems slightly deformed. A spokesperson for deepfake detection company Reality Defender said that according to their platform, the headshot is 85 percent likely to be AI-generated. [...] It is impossible to say exactly how many AI-generated books are included in Hoopla's catalog, but books that appeared to be AI-generated were not hard to find for most of the search terms I tried on the platform. "This type of low quality, AI generated content, is what we at 404 Media and others have come to call AI slop," writes Emanuel Maiberg. "Librarians, whose job it is in part to curate what books their community can access, have been dealing with similar problems in the publishing industry for years, and have a different name for it: vendor slurry."

"None of the librarians I talked to suggested the AI-generated content needed to be banned from Hoopla and libraries only because it is AI-generated. It might have its place, but it needs to be clearly labeled, and more importantly, provide borrowers with quality information."

Sarah Lamdan, deputy director of the American Library Association, told 404 Media: "Platforms like Hoopla should offer libraries the option to select or omit materials, including AI materials, in their collections. AI books should be well-identified in library catalogs, so it is clear to readers that the books were not written by human authors. If library visitors choose to read AI eBooks, they should do so with the knowledge that the books are AI-generated."

The DeepComputing RISC-V Mainboard that Framework announced last year for its 13-inch laptops is now available for $199. Liliputing reports: If you already have a Framework Laptop 13 with an Intel or AMD motherboard, the new board is a drop-in replacement. But if you don't have a Framework Laptop you can also use the mainboard as a standalone computer: Framework sells a $39 Cooler Master case that effectively turns its mainboards into mini desktop computers. The RISC-V Mainboard comes from a partnership between Framework and DeepComputing, the Chinese company behind the DC-ROMA laptops, which were some of the first notebook computers to ship with RISC-V processors.

The board features a StarFive JH7110 processor, which is a 1.5 GHz quad-core chip featuring SiFive U74 RISC-V CPU cores and Imagination BXE-4-32 graphics, 8GB of onboard RAM, and a a 64GB SD card for storage (there's also support for an optional eMMC module, but you'll need to bring your own). Since the board is designed to fit in existing laptop frames, it's the same size and shape as AMD or Intel models and has four USB ports in the same locations. But these ports are a little less versatile than the ones you might find on other Framework Laptop 13 Mainboards [...]. There's also a 3.5mm audio jack. You can check out the new board via the Framework Marketplace.

Further reading: Late last year, Framework CEO Nirav Patel delivered one of the best live demos we've ever seen at a tech conference -- modifying a Framework Laptop from x86 to RISC-V live on stage.

Americans quit 39.6 million jobs in 2024, an 11% drop from 2023 and 22% below the 2022 peak, Labor Department data showed Tuesday, signaling an end to the post-pandemic job-switching frenzy. The monthly quit rate fell below pre-pandemic levels as workers faced diminishing options in a cooling labor market. Available positions per unemployed worker dropped to 1.1 from 2 in March 2022, while hiring declined to a monthly average of 3.5% in 2024 from 4.4% in 2021.

Total hiring fell to 66 million in 2024 from 71 million in 2023, though the job market remained stable. The unemployment rate held at 4.1%, with economists expecting steady job growth in Friday's upcoming labor report. The Conference Board's latest survey showed fewer respondents viewing jobs as plentiful compared to the early 2020s, with more reporting difficulties finding work.

The proportion of people being diagnosed with lung cancer who have never smoked is increasing, with air pollution an "important factor," the World Health Organization's cancer agency has said. From a report: Lung cancer in people who have never smoked cigarettes or tobacco is now estimated to be the fifth highest cause of cancer deaths worldwide, according to the International Agency for Research on Cancer (IARC). Lung cancer in never-smokers is also occurring almost exclusively as adenocarcinoma, which has become the most dominant of the four main subtypes of the disease in both men and women globally, the IARC said.

About 200,000 cases of adenocarcinoma were associated with exposure to air pollution in 2022, according to the IARC study published in the Lancet Respiratory Medicine journal. The largest burden of adenocarcinoma attributable to air pollution was found in east Asia, particularly China, the study found.

Chris Anderson, who transformed TED from a small conference into a global platform for sharing ideas, announced today he's stepping down after 25 years at the helm. The nonprofit's leader is seeking new ownership through an unusual open call for proposals. Anderson told WIRED he wants potential buyers -- whether universities, philanthropic organizations, media companies or tech firms -- to demonstrate both vision and financial capacity.

The organization, which charges $12,500 for its flagship conference seats, maintains $25 million in cash reserves and reports a $100 million break-even balance sheet. The future owner must commit to keeping the conference running and maintaining TED's practice of sharing talks for free.

The Department of Homeland Security's Inspector General has launched an audit of the TSA's use of facial recognition technology at U.S. airports following concerns from lawmakers and privacy advocates. The Register reports: Homeland Security Inspector General Joseph Cuffari notified a bipartisan group of US Senators who had asked for such an investigation last year that his office has announced an audit of TSA facial recognition technology in a letter [PDF] sent to the group Friday. "We have reviewed the concerns raised in your letter as part of our work planning process," said Cuffari, a Trump appointee who survived the recent purge of several Inspectors General. "[The audit] will determine the extent to which TSA's facial recognition and identification technologies enhance security screening to identify persons of interest and authenticate flight traveler information while protecting passenger privacy," Cuffari said.

The letter from the Homeland Security OIG was addressed to Senator Jeff Merkley (D-OR), who co-led the group of 12 Senators who asked for an inspection of TSA facial recognition in November last year. "Americans don't want a national surveillance state, but right now, more Americans than ever before are having their faces scanned at the airport without being able to exercise their right to opt-out," Merkley said in a statement accompanying Cuffari's letter. "I have long sounded the alarm about the TSA's expanding use of facial recognition ... I'll keep pushing for strong Congressional oversight."

[...] While Cuffari's office was light on details of what would be included in the audit, the November letter from the Senators was explicit in its list of requests. They asked for the systems to be evaluated via red team testing, with a specific investigation into effectiveness - whether it reduced screening delays, stopped known terrorists, led to workforce cuts, or amounted to little more than security theater with errors.

U.S. President Donald Trump signed an executive order on Monday ordering the U.S. Treasury and Commerce Departments to create a sovereign wealth fund and said it may purchase TikTok. From a report: "We're going to stand this thing up within the next 12 months. We're going to monetize the asset side of the U.S. balance sheet for the American people," Treasury Secretary Scott Bessent told reporters. "There'll be a combination of liquid assets, assets that we have in this country as we work to bring them out for the American people."

Trump had previously floated such a government investment vehicle as a presidential candidate, saying it could fund "great national endeavors" like infrastructure projects such as highways and airports, manufacturing, and medical research. Details on how exactly the fund would operate and be financed were not immediately available, but Trump previously said it could be funded by "tariffs and other intelligent things." Typically such funds rely on a country's budget surplus to make investments, but the U.S. operates at a deficit.

U.S. Representative Zoe Lofgren has introduced a bill that would allow courts to block access to foreign websites primarily engaged in copyright infringement. The Foreign Anti-Digital Piracy Act would enable rightsholders to obtain injunctions requiring large Internet service providers and DNS resolvers to block access to pirate sites.

The bill marks a shift from previous site-blocking proposals, notably including DNS providers like Google and Cloudflare with annual revenues above $100 million. Motion Picture Association CEO Charles Rivkin backed the measure, while consumer group Public Knowledge criticized it as "censorious." The legislation requires court review and due process before any blocking orders can be issued. Sites would have 30 days to contest preliminary orders.

The blog OMG Ubuntu reports: Ubuntu's key developers have agreed to switch to Matrix as the primary platform for real-time development communications involving the distro. From March, Matrix will replace IRC as the place where critical Ubuntu development conversations, requests, meetings, and other vital chatter must take place... Only the current #ubuntu-devel and #ubuntu-release Libera IRC channels are moving to Matrix, but other Ubuntu development-related channels can choose to move — officially, given some projects were using Matrix over IRC already.

As a result, any major requests to/of the key Ubuntu development teams with privileged access can only be actioned if requests are made on Matrix. Canonical-employed Ubuntu developers will be expected to be present on Matrix during working hours... The aim is to streamline organisation, speed up decision making, ensure key developers are reliably reachable, and avoid discussions and conversations from fragmenting across multiple platforms... It's hoped that in picking one platform as the 'chosen one' the split in where the distro's development discourse takes place can be reduced and greater transparency in how and when decisions are made restored.

IRC remains popular with many Ubuntu developers but its old-school, lo-fi nature is said to be off-putting to newer contributors. They're used to richer real-time chat platforms with more features (like discussion history, search, offline messaging, etc). It's felt this is why many newer developers employed by Canonical prefer to discuss and message through the company's internal Mattermost instance — which isn't publicly accessible. Many Ubuntu teams, flavours, and community chats already take place on Matrix...
"End-users aren't directly affected, of course," they point out. But an earlier post on the same blog notes that Matrix "is increasingly ubiquitous in open-source circles. GNOME uses it, KDE embraces it, Linux Mint migrated last year, Mozilla a few years before, and it's already widely used by Ubuntu community members and developers." IRC remains unmatched in many areas but is, rightly or wrongly, viewed as an antiquated communication platform. IRC clients aren't pretty or plentiful, the syntax is obtuse, and support for 'modern' comforts like media sending, read receipts, etc., is lacking.To newer, younger contributors IRC could feel ancient or cumbersome to learn.

Though many of IRC's real and perceived shortcomings are surmountable with workarounds, clients, bots, scripts, and so on, support for those varies between channels, clients, servers, and user configurations. Unlike IRC, which is a centralised protocol relying on individual servers, Matrix is federated. It lets users on different servers to communicate without friction. Plus, Matrix features encryption, message history, media support, and so, meeting modern expectations.

An anonymous reader shared this post from the blog OMG Ubuntu Want to find out if the text you're reading online was written by an real human or spat out by a large language model trying to sound like one? Mozilla's Fakespot Deepfake Detector Firefox add-on may help give you an indication. Similar to online AI detector tools, the add-on can analyse text (of 32 words or more) to identify patterns, traits, and tells common in AI generated or manipulated text.

It uses Mozilla's proprietary ApolloDFT engine and a set of open-source detection models. But unlike some tools, Mozilla's Fakespot Deepfake Detector browser extension is free to use, does not require a signup, nor an app download. "After installing the extension, it is simple to highlight any text online and request an instant analysis. Our Detector will tell you right away if the words are likely to be written by a human or if they show AI patterns," Mozilla says.

Fakespot, acquired by Mozilla in 2023, is best known for its fake product review detection tool which grades user-submitted reviews left on online shopping sites. Mozilla is now expanding the use of Fakespot's AI tech to cover other kinds of online content. At present, Mozilla's Fakespot Deepfake Detector only works with highlighted text on websites but the company says it image and video analysis is planned for the future.
The Fakespot web site will also analyze the reviews on any product-listing pages if you paste in its URL.

An aircraft carrier in the U.S. Navy tested "vastly increased" levels of internet connectivity, reports the defense-news web site TWZ, callling it "a game-changer for what a ship, and its sailors, can do while at sea." The F-35 Joint Strike Fighters assigned to the carrier offer a case in point for what more shipboard bandwidth — provided by commercial providers like Starlink and OneWeb — can mean at the tactical level. Jets with the embarked Marine Fighter Attack Squadron 314 took on critical mission data file updates in record time last fall due to the carrier's internet innovations, a capability that is slated to expand across the fleet. "This file offers intelligence updates and design enhancements that enable pilots to identify and counter threats in specific operational environments," the Navy said in an October release announcing the feat. "The update incorporated more than 100 intelligence changes and multiple design improvements, significantly enhancing the aircraft's survivability and lethality...." [Capt. Kevin White, then the Lincoln's combat systems officer] noted how the F-35 "eats and breathes data daily," and it has to be shared with commands ashore. The connectivity innovations he's pioneered will enable such data transfers, which will only grow more complex over time. "If you can't get the data onboard, you're probably going to be at a loss," White said. "So large file transfer capability increases combat readiness...."

When the system was on, it provided not only mission benefits, but benefits to the hard-working Lincoln crew as well, which was at sea for 107 days at one point with no port calls [Capt. Pete "Repete" Riebe, told WEST conference attendees]... White said the average age of an embarked Lincoln sailor was 20.8, and Riebe noted that to attract young people into service, the Navy needs to recognize the innate connection they have to their devices. "The next generation of sailors grew up with a cell phone in their hand, and they are uncomfortable without it," Riebe said. "I don't necessarily like that, but that's reality, and if we want to compete for the best folks coming into the Navy, we need to offer them bandwidth at sea." Having better connectivity also helped with the ship's administrative functions, Riebe said, making medical, dental and other work far easier than they have been in the past...

A sailor who can FaceTime with his family back home carries less non-Navy stress with them as they focus on the life-or-death duties at hand, White said... This beefed-up bandwidth allowed 38 sailors to witness the birth of their child, while others were able to watch their kids' sporting events, White said. Several crew members pursued doctorate and master's degrees while deployed due to better internet, while others were able to deal with personal or legal issues they had left behind back home. One officer was able to commission his wife remotely from the ship... On the operational side, from "the most desolate waters," Lincoln used its bandwidth to connect with a command in Norfolk, which undertook the ship's annual cybersecurity scans "from halfway around the world," White said... Taxpayer dollars can also be saved if a ship isn't paying for WiFi access while in port, White noted, and the crew was able to start getting to know Italian allies online before an exercise, enhancing the personal aspects of such partnerships.

More bandwidth also means more onboard training, meaning some sailors who don't have to leave to go to the school house, and sailors were able to get answers to maintenance questions from ashore commands faster as well. "Just by being able to have more reliable access to support resources, we definitely become more effective at maintenance," White said.
Every day the aircraft carrier averaged four to eight terabytes of transferred data, according to the article (with a team of two full-time system administrators managing 7,000 IP addresses), and ultimately saw 780 terabytes of data transferred over five-and-a-half months. The article notes it's part of the Navy's larger "Sailor Edge Afloat and Ashore" (SEA2) program to provide all its warships with high-bandwidth connectivity around the world.

The program "involves moving some communications aspects away from proprietary Defense Department satellites, while leaning on commercial satellite constellations and even cellular providers to keep ships more connected at sea for both personal and tactical uses."

Bill Gates' blog has been updated with short videos about his upcoming book, including one about how his school ended up with an ASR-33 teletype that could connect their Seattle classroom to a computer in California. "The teachers faded away pretty quickly," Gates adds, "But about six of us stayed hardcore. One was Paul Allen..." — the future co-founder of Microsoft. And the experience clearly meant a lot to Gates. "Microsoft just never would've happened without Paul — and this teletype room."

In a longer post thanking his "brilliant" teachers, Gates calls his teletype experience "an encounter that would shape my entire future" and "opened up a whole new world for me." Gates also thanks World War II Navy pilot and Boeing engineer Bill Dougall, who "was instrumental in bringing computer access to our school, something he and other faculty members pushed for after taking a summer computer class... The fascinating thing about Mr. Dougall was that he didn't actually know much about programming; he exhausted his knowledge within a week. But he had the vision to know it was important and the trust to let us students figure it out."

Gates shared a similar memory about the computer-room's 20-something overseer Fred Wright, who "intuitively understood that the best way to get students to learn was to let us explore on our own terms. There was no sign-up sheet, no locked door, no formal instruction." Instead, Mr. Wright let us figure things out ourselves and trusted that, without his guidance, we'd have to get creative... Some of the other teachers argued for tighter regulations, worried about what we might be doing in there unsupervised. But even though Mr. Wright occasionally popped in to break up a squabble or listen as someone explained their latest program, for the most part he defended our autonomy...

Mr. Wright gave us something invaluable: the space to discover our own potential.

On January 24th Brooklyn blogger Jeffrey Emanuel made the case for shorting NVIDIA, remembers MarketWatch, "due to a number of shifting tides in the AI world, including the emergence of a China-based company called DeepSeek."

He published his 12,000-word post "on his personal blog and then shared it with the Value Investors Club website and across Reddit, X and other platforms." The next day he saw 35 people read his post. "But then the post started to go viral..." Well-known venture capitalist Chamath Palihapitiya shared Emanuel's post on Nvidia's short case with his 1.8 million X followers. Successful early stage investor Naval Ravikant shared the post with his 2.6 million followers... Morgan Brown, a vice president of product and growth at Dropbox, pointed to it in a thread that was viewed over 13 million times. Emanuel's own X post got nearly half a million views. He also quickly gained about 13,000 followers on the platform, going from about 2,000 to more than 15,000 followers...

[Emanuel] pointed to the fact that so many people in San Jose were reading his blog post. He theorized that many of them were Nvidia employees with thousands — or even millions — of dollars worth of Nvidia stock tied up in employee stock options. With that much money in a single asset, Emanuel speculated that many were already debating whether to hold the stock or sell it to lock in profits. He believes his blog post helped convince some of them to sell. "A lot of the sell pressure you saw on Monday morning wasn't necessarily what you might think. I believe a fair amount of that was from shares that had never been active because they had been sitting in workplace.schwab.com accounts..."
Emanuel stresses he's "the most bullish on AI," with MarketWatch emphasizing that "while the points Emanuel laid out in his blog post might be bearish for Nvidia, he still thinks they paint a positive future for AI." Nevertheless, Monday NVIDIA's market capitalization dropped $600 billion, which MarketWatch calls "the largest single-day market-cap drop to date for any company." What countless Wall Street firms and investment analysts had seemingly missed was being pointed out by some guy in his apartment.... Matt Levine, the prominent Bloomberg News financial columnist, noted the online chatter that claimed Emanuel's post "was an important catalyst" for the stock-market selloff and said it was a "candidate for the most impactful short research report ever." Emanuel spent the rest of the week booked solid as hedge funds paid him $1,000 per hour to speak on the phone and give his take on Nvidia and AI...

Emanuel wrote that the industry may be running low on quality data to train that AI — that is, a potential "data wall" is looming that could slow down AI scaling and reduce some of that need for training resources... Some of these companies, like Alphabet, have also been investing in building out their own semiconductor chips. For a while, Nvidia's hardware has been the best for training AI, but that might not be the case forever as more companies, such as Cerebras, build better hardware. And other GPU makers like AMD are updating their drivers software to be more competitive with Nvidia... Add all these things together — unsustainable spending and data-center building, less training data to work with, better competing hardware and more efficient AI — and you get a future where it's harder to imagine Nvidia's customers spending as much as they currently are on Nvidia hardware... "If you know that a company will only earn supersized returns for a couple years, you don't apply a multiple. You certainly don't put a 30-times multiple," Emanuel told MarketWatch.
The article notes that DeepSeek "is open-source and has been publishing technical papers out in the open for the past few months... The $5.6 million training-cost statistic that many investors cited for sparking the DeepSeek market panic was actually revealed in the V3 technical paper published on Dec. 26."

Wednesday the Linux Foundation wrote that both "regulatory compliance" and "increased cybersecurity risk" were "creating burdens...that must be met" for open source communities.

And so, as Steven J. Vaughan-Nichols writes, "the Linux Foundation has released a comprehensive guide to help open source developers navigate the complex landscape of the U.S. Office of Foreign Assets Control (OFAC) sanctions..." These rules, aimed at achieving economic, foreign policy, and national security goals, apply to various interactions, including those in the open source community. The total Sanctions Programs and Country list amounts to over 17 thousand entries ranging from individuals to terrorist organizations to countries.

If that rings a bell, it's because, in October 2024, the Linux kernel developers ran right into this issue. The Linux kernel's leadership, including Greg Kroah-Hartman, the stable Linux kernel maintainer, and Linus Torvalds, Linux's founder, announced that eleven Russian kernel developers had been removed from their roles working on the Linux kernel. Why? Because, as Torvalds said, of "Russian sanctions." This, he added, in a Linux kernel mailing list (LKML) message was because "the 'various compliance requirements' are not just a US thing."

For developers, this means exercising caution about who they interact with and where their contributions originate. The sanctions target specific countries, regions, and individuals or organizations, many of which are listed on the Specially Designated Nationals and Blocked Persons (SDN) List... Most OFAC sanctions are exempted for "informational materials," which generally include open source code. However, this only applies to existing code and not to requests for new code or modifications. So, for example, working with a Russian developer on a code patch could land you in hot water... While reviewing unsolicited patches from contributors in sanctioned regions is generally acceptable, actively engaging them in discussions or improvements could cross legal boundaries... Developers are warned to be cautious of sanctioned entities attempting to contribute indirectly through third parties or developers acting "individually."
Countries currently sanctioned include:

• Russia
• Cuba
• Iran
• North Korea
• Syria
• The following regions of Ukraine: Crimea, Donetsk and Luhansk regions of the Ukraine.

The Linux Foundation had written that the OFAC sanctions rules are "strict liability" rules, "which means it does not matter whether you know about them or not. Violating these rules can lead to serious penalties, so it's important to understand how they might affect your open source work." But J. Vaughan-Nichols offers this quote from open source licensing attorney Heather Meeker.

"Let's be honest: Smaller companies usually ignore regulations like this because they just don't have the resources to analyze them, and a government usually ignores smaller companies because it doesn't have the resources to enforce against them. Big companies that are on the radar need specialized counsel."

"Sometimes, government makes a bad bet..." writes the Los Angeles Times. Opening in 2014, the Ivanpah concentrated solar plant "quickly became known as an expensive, bird-killing eyesore." Assuming that state officials sign off — which they most likely will, because the deal will lead to lower bills for PG&E customers — two of the three towers will shut down come 2026. Ivanpah's owners haven't paid off the project's $1.6-billion federal loan, and it's unclear whether they'll be able to do so. Houston-based NRG Energy, which operates Ivanpah and is a co-owner with Kelvin Energy and Google, said that federal officials took part in the negotiations to close PG&E's towers and that the closure agreement will allow the federal government "to maximize the recovery of its loans." It's possible Ivanpah's third and final tower will close, too. An Edison spokesperson told me the utility is in "ongoing discussions" with the project's owners and the federal government over ending the utility's contract.

It might be tempting to conclude government should stop placing bets and just let the market decide. But if it weren't for taxpayers dollars, large-scale solar farms, which in 2023 produced 17% of California's power, might never have matured into low-cost, reliable electricity sources capable of displacing planet-warming fossil fuels. More than a decade ago, federal loans helped finance some of the nation's first big solar-panel farms.

Not every government investment will be a winner. Renewable energy critics still raise the specter of Solyndra, a solar panel manufacturer that filed for bankruptcy in 2011 after receiving a $535-million federal loan. But on the whole, clean power investments have worked out. The U.S. Department of Energy reported that as of Dec. 31, it had disbursed $40.5 billion in loans. Of that amount, $15.2 billion had already been repaid. The federal government was on the hook for $1.03 billion in estimated losses but had reaped $5.6 billion in interest.
The article notes recent U.S. energy-related loans to a lithium mine in Nevada (close to $1 billion) and $15 billion to expand hydropower, upgrade power lines, and add batteries. Some of the loans won't get paid back "If federal officials are doing their jobs well," the article adds. "That's the risk inherent to betting on early-stage technologies." About the Ivanpah solar towers, they write "Maybe they never should have been built. They're too expensive, they don't work right, they kill too many birds... It's good that their time is coming to an end. But we should take inspiration from them, too: Don't get complacent. Keep trying new things."

PG&E says their objective at the time was partly to "support new technologies," with one senior director of commercial procurement noting "It's not clear in the early stages what technologies will work best and be most affordable for customers. Solar photovoltaic panels and battery energy storage were once unaffordable at large scale." But today they've calculated that ending their power agreements with Ivanpah would cost customers "substantially less." And once deactivated, Ivanpah's units "will be decommissioned, providing an opportunity for the site to potentially be repurposed for renewable PV energy production," NRG said in a statement.

The Las Vegas Review-Journal notes that instead the 3,500-acre, 386-megawatt concentrated thermal power plant used a much older technology, "a system of mirrors to reflect sunlight and generate thermal energy, which is then concentrated to power a steam engine." Throughout the day, 350,000 computer-controlled mirrors track the sunlight and reflect it onto boilers atop 459-foot towers to generate AC. Nowadays, photovoltaic solar has surpassed concentrated solar power and become the dominant choice for renewable, clean energy, being more cost effective and flexible... So many birds have been victims of the plant's concentrated sun rays that workers referred to them as "streamers," for the smoke plume that comes from birds that ignite in midair. When federal wildlife investigators visited the plant around 10 years ago, they reported an average of one "streamer" every two minutes.
"Meanwhile, environmentalists continue to blame the Mojave Desert plant for killing thousands of birds and tortoises," reports the Associated Press. And a Sierra Club campaign organizer also says several rare plant species were destroyed during the plant's construction. "While the Sierra Club strongly supports innovative clean energy solutions and recognizes the urgent need to transition away from fossil fuels, Ivanpah demonstrated that not all renewable technologies are created equal."
