Abstract of a paper on NBER: This paper documents video consumption among school-aged children in the U.S. and explores its impact on human capital development. Video watching is common across all segments of society, yet surprisingly little is known about its developmental consequences. With a bunching identification strategy, we find that an additional hour of daily video consumption has a negative impact on children's noncognitive skills, with harmful effects on both internalizing behaviors (e.g., depression) and externalizing behaviors (e.g., social difficulties). We find a positive effect on math skills, though the effect on an aggregate measure of cognitive skills is smaller and not statistically significant. These findings are robust and largely stable across most demographics and different ways of measuring skills and video watching. We find evidence that for Hispanic children, video watching has positive effects on both cognitive and noncognitive skills -- potentially reflecting its role in supporting cultural assimilation. Interestingly, the marginal effects of video watching remain relatively stable regardless of how much time children spend on the activity, with similar incremental impacts observed among those who watch very little and those who watch for many hours.

Authorities in Iran have sprayed clouds with chemicals to induce rain, in an attempt to combat the country's worst drought in decades. From a report: Known as cloud-seeding, the process was conducted over the Urmia lake basin on Saturday, Iran's official news agency Irna reported. Urmia is Iran's largest lake, but has largely dried out leaving a vast salt bed. Further operations will be carried out in east and west Azerbaijan, the agency said. Rainfall is at record lows and reservoirs are nearly empty. Last week President Masoud Pezeshkian warned that if there is not enough rainfall soon, Tehran's water supply could be rationed and people may be evacuated from the capital. Cloud seeding involves injecting chemical salts including silver or potassium iodide into clouds via aircraft or through generators on the ground. Water vapour can then condense more easily and turn into rain. The technique has been around for decades, and the UAE has used it in recent years to help address water shortages. Iran's meteorological organisation said rainfall had decreased by about 89% this year compared with the long-term average, Irna reported.

An anonymous reader shares a report: The use of AI in the latest Call of Duty has prompted a US lawmaker to call for regulations to prevent artificial intelligence from taking jobs away from human workers. Rep. Ro Khanna (D-Calif.), who represents a large swathe of Silicon Valley, took aim at Call of Duty: Black Ops 7 after buyers noticed the popular shooter contains a significant amount of AI-generated icons, posters, and achievements. Gamers are criticizing it as filled with "AI slop." On Friday, Khanna tweeted: "We need regulations that prevent companies from using AI to eliminate jobs to extract greater profits." He added, "Artists at these companies need to have a say in how AI is deployed. They should share in the profits. And there should be a tax on mass displacement."

Strauss Zelnick, CEO of Take-Two Interactive, which operates publishing labels including GTA-maker Rockstar Games and 2K, said on Monday that although gaming consoles are not going away, the industry is moving toward PCs in the next decade. From a report: "I think it's moving towards PC and business is moving towards open rather than closed," Zelnick told CNBC's "Squawk Box." "But if you define console as the property, not the system, then the notion of a very rich game that you engage in for many hours that you play on a big screen -- that's never going away." Zelnick said the current split between console and mobile is about even in the market, but mobile is growing more rapidly than consoles.

The UK government has been warned that its plan to ban operators of critical national infrastructure from paying ransoms to hackers is unlikely to stop cyber attacks and could result in essential services collapsing. From a report: The proposal, announced by the Home Office in July, is designed to deter cyber criminals by making it clear any attempt to blackmail regulated companies such as hospitals, airports and telecoms groups will not succeed. If enacted, the UK would be the first country to implement such a ban. But companies and cyber groups have told government officials that making paying ransoms illegal would remove a valuable tool in negotiations where highly sensitive data or essential services could be compromised, according to two people familiar with the matter. "An outright ban on payments sounds tough on crime, but in reality it could turn a solvable crisis into a catastrophic one," said Greg Palmer, a partner at law firm Linklaters.

For better or for worse, the NUMA node is the abstraction used by the kernel to keep track of different types of memory. How that abstraction is used, though, is still an active area of development. Two patch sets focused on this problem are currently under review; one addresses the perennial problem of promoting heavily used folios from slower to faster memory, while the other aims to improve the kernel's handling of nodes containing special memory installed for a specific purpose.

Global internet freedom declined for a 15th consecutive year, according to Freedom House's annual report. Semafor: "Always grim reading," this year's is particularly sobering, Tech Policy Press noted, with the lowest-ever portion of users living in countries categorized as "free." Conditions declined in 27 of the 72 countries assessed, with those in Kenya -- where anti-corruption protests were quelled, in part, by a seven-hour internet shutdown -- deteriorating the most. China and Myanmar tied for least-free, and the US' ranking dropped, while Iceland retained its top spot for the freest digital environment. Bangladesh improved the most. The most consistent trend observed over 15 years, Freedom House noted, is the growing digital influence of state actors: "Online spaces are more manipulated than ever."

Hotel cancellation policies have transformed over the past seven years. Travelers once could cancel reservations up until the day before check-in without penalty. That flexibility has largely vanished. The shift began around 2018 when third-party travel-booking sites deployed "cancel-rebook" strategies, the Atlantic writes. These platforms would monitor hotel rates after securing initial reservations. When prices dropped, the sites automatically canceled existing bookings and rebooked customers at lower rates. Hotels lost already-booked revenue whenever they reduced prices to fill empty rooms. Hotels responded by introducing tiered pricing structures. Travelers now encounter prepaid non-refundable rates at the lowest price point, mid-range rates with two- or three-day cancellation deadlines, and higher rates for same-day cancellation flexibility. The cancel-rebook sites could still swap reservations until deadlines arrived, but the damage to hotels diminished. Christopher Anderson, a professor at Cornell University's Nolan School of Hotel Administration, told the outlet that hotel cancellations differ from airline cancellations. Most hotels operate as franchises rather than centrally-owned properties. A canceled Ithaca Marriott reservation cannot be converted to credit at a New York Marriott Marquis because different owners operate each location. Anderson suggests travelers call hotels directly to request exceptions. Hilton confirmed it evaluates cancellation waivers case-by-case and extends broad waivers during natural disasters or major disruptions.

Anthropic CEO Dario Amodei says he's uneasy about how much power a handful of tech leaders -- including himself -- have over the future of artificial intelligence. From a report: "I think I'm deeply uncomfortable with these decisions being made by a few companies, by a few people," Amodei told Anderson Cooper in a "60 Minutes" episode that aired Sunday. "Like who elected you and Sam Altman?" asked Anderson. "No one. Honestly, no one," Amodei replied.

Debian developer Simon Josefsson has announced the Debian Libre Live Images project, to allow installing Debian without any non-free software:

Since the 2022 decision on non-free firmware, the official images for bookworm and trixie contains non-free software.

The Debian Libre Live Images project provides Live ISO images for Intel/AMD-compatible 64-bit x86 CPUs (amd64) built without any non-free software, suitable for running and installing Debian. The images are similar to the Debian Live Images distributed as Debian live images.

He does warn that this is a first public release, so there may be problems. See the current list of known issues before trying the images out.

An anonymous reader shares a report: Elementary-school students would have to learn how to write in cursive, under a bill set to be vetted by a House committee next week. Sen. Erin Grall, R-Vero Beach, filed a similar proposal (SB 444) on Monday. The House Student Academic Success Subcommittee is set to review the measure (HB 127) on Nov. 18. Sponsored by Rep. Toby Overdorf, R-Palm City, the bill would require cursive instruction in second through fifth grades. The proposal, filed for consideration for the legislative session that begins Jan. 13, also would require students to demonstrate proficiency in cursive by the end of fifth grade.

Jeff Bezos has founded an AI startup called Project Prometheus and will serve as its co-chief executive. This is his first formal operational role since stepping down as chief executive of Amazon in July 2021. The company has raised $6.2 billion in funding, The New York Times reports, partly from Bezos. The funding makes Project Prometheus one of the most well-financed early-stage startups in the world. Bezos's co-founder and co-chief executive is Vik Bajaj, a physicist and chemist who worked closely with Google co-founder Sergey Brin at Google X. Dr. Bajaj was among the founders of Verily in 2015 and co-founded Foresite Labs in 2018. He recently left that position to focus on Project Prometheus. The company is focusing on AI for engineering and manufacturing in computers, aerospace, and automobiles. The startup has already hired nearly 100 employees, the report said. Researchers from OpenAI, DeepMind, and Meta are among the hires. Project Prometheus is building AI systems that learn from physical experiments rather than just analyzing digital text.

Linux kernel maintainers "are grappling with how to integrate AI-generated contributions without compromising the project's integrity," reports WebProNews: The latest push comes from a proposal by Sasha Levin, a prominent kernel developer at NVIDIA, who has outlined guidelines for tool-generated submissions. Posted to the kernel mailing list, these guidelines aim to standardize how AI-assisted patches are handled. According to Phoronix, the v3 iteration of the proposal [posted by Intel engineer Dave Hansen] emphasizes transparency and accountability, requiring developers to disclose AI involvement in their contributions. This move reflects broader industry concerns about the quality and copyright implications of machine-generated code. Linus Torvalds, the creator of Linux, has weighed in on the debate, advocating for treating AI tools no differently than traditional coding aids. As reported by heise online, Torvalds sees no need for special copyright treatment for AI contributions, stating that they should be viewed as extensions of the developer's work. This perspective aligns with the kernel's pragmatic approach to innovation. The proposal, initially put forward by Levin in July 2025, includes a 'Co-developed-by' tag for AI-assisted patches, ensuring credit and traceability. OSTechNix details how tools like GitHub Copilot and Claude are specifically addressed, with configurations to guide their use in kernel development... ZDNET warns that without official policy, AI could 'creep' into the kernel and cause chaos... The New Stack provides insight into how AI is already assisting kernel maintainers with mundane tasks. According to The New Stack, large language models (LLMs) are being used like 'novice interns' for drudgery work, freeing up experienced developers for complex problems... The Linux kernel's approach could set precedents for other open-source projects. With AI integration accelerating, projects like those in the Linux Foundation are watching closely... Recent kernel releases, such as 6.17.7, include performance improvements that indirectly support AI applications, as noted in Linux Compatible.

655"Just a little more than a month after reaching an all-time high, Bitcoin has erased the more than 30% gain registered since the start of the year..." reports Bloomberg: The dominant cryptocurrency fell below US$93,714 on Sunday, pushing the price beneath the closing level reached at the end of last year, when financial markets were rallying following President Donald Trump's election victory. Bitcoin soared to a record US$126,251 on Oct 6, only to begin tumbling four days later after unexpected comments on tariffs by Trump sent markets into a tailspin worldwide. "The general market is risk-off," said Matthew Hougan, the San Francisco-based chief investment officer for Bitwise Asset Management. "Crypto was the canary in the coal mine for that, it was the first to flinch." Over the past month, many of the biggest buyers — from exchange-traded fund allocators to corporate treasuries — have quietly stepped back, depriving the market of the flow-driven support that helped propel the token to records earlier this year. For much of the year, institutions were the backbone of Bitcoin's legitimacy and its price. ETFs as a cohort took in more than US$25 billion, according to Bloomberg data, pushing assets as high as roughly US$169 billion. Their steady allocation flows helped reframe the asset as a portfolio diversifier — a hedge against inflation, monetary debasement and political disarray. But that narrative — always tenuous — is fraying afresh, leaving the market exposed to something quieter but no less destabilising: disengagement. "The selloff is a confluence of profit-taking by LTHs, institutional outflows, macro uncertainty, and leveraged longs getting wiped out," said Jake Kennis, senior research analyst at Nansen. "What is clear is that the market has temporarily chosen a downward direction after a long period of consolidation/ranging..." Boom and bust cycles have been a constant since Bitcoin burst into the mainstream consciousness with a more than 13,000% surge in 2017, only to be followed by a plunge of almost 75% the following year... Bitcoin has whipsawed investors through the year, dropping to as low as US$74,400 in April as Trump unveiled his tariffs, before rebounding to record highs ahead of the latest retreat... The market downturn has been even tougher on smaller, less liquid tokens that traders often gravitate toward because of their higher volatility and typical outperformance during rallies. A MarketVector index tracking the bottom half of the largest 100 digital assets is down around 60% this year.

"To be clear, the current economics of space-based data centers don't make sense," writes the Wall Street Journal. "But they could in the future, perhaps as soon as a decade or so from now, according to an analysis by Phil Metzger, a research professor at the University of Central Florida and formerly of the National Aeronautics and Space Administration." "Space enthusiasts (comme moi) have long sought a business case to enable human migration beyond our home world," he posted on X amid the new hype. "I think AI servers in space is the first real business case that will lead to many more...." The argument essentially boils down to the belief that AI's needs are eventually going to grow so great that we need to move to outer space. There the sun's power can be more efficiently harvested. In space, the sun's rays can be direct and constant for solar panels to collect — no clouds, no rainstorms, no nighttime. Demands for cooling could also be cut because of the vacuum of space. Plus, there aren't those pesky regulations that executives like to complain about, slowing construction of new power plants to meet the data-center needs. In space, no one can hear the Nimbys scream. "We will be able to beat the cost of terrestrial data centers in space in the next couple of decades," Bezos said at a tech conference last month. "Space will end up being one of the places that keeps making Earth better." It's still early days. At Alphabet, Google's plans sound almost conservative. The search-engine company in recent days announced Project Suncatcher, which it describes as a moonshot project to scale machine learning in space. It plans to launch two prototype satellites by early 2027 to test its hardware in orbit. "Like any moonshot, it's going to require us to solve a lot of complex engineering challenges," Pichai posted on social media. Nvidia, too, has announced a partnership with startup Starcloud to work on space-based data centers. Not to be outdone, Elon Musk has been painting his own updated vision for the heavens... in recent weeks he has been talking more about how he can use his spaceships to deploy new versions of his solar-powered Starlink satellites equipped with high-speed lasers to build out in-space data centers. On Friday, Musk further reiterated how those AI satellites would be able to generate 100 gigawatts of annual solar power — or, what he said, would be roughly a quarter of what the U.S. consumes on average in a year. "We have a plan mapped out to do it," he told investor Ron Baron during an event. "It gets crazy." Previously, he has suggested he was four to five years away from that ability. He's also touted even wilder ideas, saying on X that 100 terawatts a year "is possible from a lunar base producing solar-powered AI satellites locally and accelerating them to escape velocity with a mass driver." Simply put, he's suggesting a moon base will crank out satellites and throw them into orbit with a catapult. And those satellites' solar panels would generate 100,000 gigawatts a year. "I think we'll see intelligence continue to scale all the way up to where...most of the power of the sun is harnessed for compute," Musk told a tech conference in September.

"Windows is evolving into an agentic OS," Microsoft's president of Windows Pavan Davuluri posted on X.com, "connecting devices, cloud, and AI to unlock intelligent productivity and secure work anywhere." But former Uber software engineer and engineering manager Gergely Orosz was unimpressed. "Can't see any reason for software engineers to choose Windows with this weird direction they are doubling down on. So odd because Microsoft has building dev tools in their DNA... their OS doesn't look like anything a builder who wants OS control could choose. Mac or Linux it is for devs." Davuluri "has since disabled replies on his original post..." notes the blog Windows Central, "which some people viewed as an attempt to shut out negative feedback." But he also replied to that comment... Davuluri says "we care deeply about developers. We know we have work to do on the experience, both on the everyday usability, from inconsistent dialogs to power user experiences. When we meet as a team, we discuss these pain points and others in detail, because we want developers to choose Windows..." The good news is Davuluri has confirmed that Microsoft is listening, and is aware of the backlash it's receiving over the company's obsession with AI in Windows 11. That doesn't mean the company is going to stop with adding AI to Windows, but it does mean we can also expect Microsoft to focus on the other things that matter too, such as stability and power user enhancements. Elsewhere on X.com, Microsoft CEO Satya Nadella shared his own thoughts on "the net benefit of the AI platform wave ." The Times of India reports: Nadella said tech companies should focus on building AI systems that create more value for the people and businesses using them, not just for the companies that make the technology. He cited Bill Gates to emphasize the same: "A platform is when the economic value of everybody that uses it exceeds the value of the company that creates it."Tesla CEO Elon Musk responded to Nadella's post with a facepalm emoji. Nadella said this idea matters even more during the current AI boom, where many firms risk giving away too much of their own value to big tech platforms. "The real question is how to empower every company out there to build their own AI-native capabilities," he wrote. Nadella says Microsoft's partnership with OpenAI is an example of zero-sum mindset industry... [He also cited Microsoft's "work to bring AMD into the fleet."] More from Satya Nadella's post: Thanks to AI, the [coding] category itself has expanded and may ultimately become one of the largest software categories. I don't ever recall any analyst ever asking me about how much revenue Visual Studio makes! But now everyone is excited about AI coding tools. This is another aspect of positive sum, when the category itself is redefined and the pie becomes 10x what it was! With GitHub Copilot we compete for our share and with GitHub and Agent HQ we also provide a platform for others. Of course, the real test of this era won't be when another tech company breaks a valuation record. It will be when the overall economy and society themselves reach new heights. When a pharma company uses AI in silico to bring a new therapy to market in one year instead of twelve. When a manufacturer uses AI to redesign a supply chain overnight. When a teacher personalizes lessons for every student. When a farmer predicts and prevents crop failure.That's when we'll know the system is working. Let us move beyond zero-sum thinking and the winner-take-all hype and focus instead on building broad capabilities that harness the power of this technology to achieve local success in each firm, which then leads to broad economic growth and societal benefits. And every firm needs to make sure they have control of their own destiny and sovereignty vs just a press release with a Tech/AI company or worse leak all their value through what may seem like a partnership, except it's extractive in terms of value exchange in the long run.

"Three Chinese astronauts returned from their nation's space station Friday," reports the Associated Press, "after more than a week's delay because the return capsule they had planned to use was damaged, likely from being hit by space debris." The team left their Shenzhou-20 spacecraft in orbit and came back using the recently arrived Shenzhou-21, which had ferried a three-person replacement crew to the station, China's Manned Space Agency said. The original return plan was scrapped because a window in the Shenzhou-20 capsule had tiny cracks, most likely caused by impact from space debris, the space agency said Friday... Their return was delayed for nine days, and their 204-day stay in space was the longest for any astronaut at China's space station... China developed the Tiangong space station after the country was excluded from the International Space Station over U.S. national security concerns. China's space program is controlled by its military.

Android's security team published a blog post this week about their experience using Rust. Its title? "Move fast and fix things." Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in new code quickly yields durable and compounding gains. This year we look at how this approach isn't just fixing things, but helping us move faster. The 2025 data continues to validate the approach, with memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time. We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android's C and C++ code. But the biggest surprise was Rust's impact on software delivery. With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one... Data shows that Rust code requires fewer revisions. This trend has been consistent since 2023. Rust changes of a similar size need about 20% fewer revisions than their C++ counterparts... In a self-reported survey from 2022, Google software engineers reported that Rust is both easier to review and more likely to be correct. The hard data on rollback rates and review times validates those impressions. Historically, security improvements often came at a cost. More security meant more process, slower performance, or delayed features, forcing trade-offs between security and other product goals. The shift to Rust is different: we are significantly improving security and key development efficiency and product stability metrics. With Rust support now mature for building Android system services and libraries, we are focused on bringing its security and productivity advantages elsewhere. Android's 6.12 Linux kernel is our first kernel with Rust support enabled and our first production Rust driver. More exciting projects are underway, such as our ongoing collaboration with Arm and Collabora on a Rust-based kernel-mode GPU driver. [They've also been deploying Rust in firmware for years, and Rust "is ensuring memory safety from the ground up in several security-critical Google applications," including Chromium's parsers for PNG, JSON, and web fonts.] 2025 was the first year more lines of Rust code were added to Android than lines of C++ code...
