Ubuntu "is adopting the memory-safe Rust language," reports ZDNet, citing remarks at this year's Ubuntu Summit from Jon Seager, Canonical's VP of engineering for Ubuntu: . Seager said the engineering team is focused on replacing key system components with Rust-based alternatives to enhance safety and resilience, starting with Ubuntu 25.10. He stressed that resilience and memory safety, not just performance, are the principal drivers: "It's the enhanced resilience and safety that is more easily achieved with Rust ports that are most attractive to me". This move is echoed in Ubuntu's adoption of sudo-rs, the Rust implementation of sudo, with fallback and opt-out mechanisms for users who want to use the old-school sudo command.

In addition to sudo-rs, Ubuntu 26.04 will use the Rust-based uutils/coreutils for Linux's default core utilities. This setup includes ls, cp, mv, and dozens of other basic Unix command-line tools. This Rust reimplementation aims for functional parity with GNU coreutils, with improved safety and maintainability.

On the desktop front, Ubuntu 26.04 will also bring seamless TPM-backed full disk encryption. If this approach reminds you of Windows BitLocker or MacOS FileVault, it should. That's the idea.
In other news, Canonical CEO Mark Shuttleworth said "I'm a believer in the potential of Linux to deliver a desktop that could have wider and universal appeal." (Although he also thinks "the open-source community needs to understand that building desktops for people who aren't engineers is different. We need to understand that the 'simple and just works' is also really important.")

Shuttleworth answered questions from Slashdot's readers in 2005 and 2012.

Longtime Slashdot reader AmiMoJo shares a report from the Financial Times: Solar power developers want to cover an area larger than Washington, DC, with silicon panels and batteries, converting sunlight into electricity that will power air conditioners in sweltering Las Vegas along with millions of other homes and businesses. But earlier this month, bureaucrats in charge of federal lands scrapped collective approval for the Esmeralda 7 projects, in what campaigners fear is part of an attack on renewable energy under President Donald Trump. "We will not approve wind or farmer destroying [sic] Solar," he posted on his Truth Social platform in August. Developers will need to reapply individually, slowing progress.

Thousands of miles away on the other side of the Pacific Ocean, it is a different story. China has laid solar panels across an area the size of Chicago high up on the Tibetan Plateau, where the thin air helps more sunlight get through. The Talatan Solar Park is part of China's push to double its solar and wind generation capacity over the coming decade. "Green and low-carbon transition is the trend of our time," President Xi Jinping told delegates at a UN summit in New York last month. China's vast production of solar panels and batteries has also pushed down the prices of renewables hardware for everyone else, meaning it has "become very difficult to make any other choice in some places," according to Heymi Bahar, senior analyst at the International Energy Agency. [...]

More broadly, the US's focus on fossil fuels and pullback of support for clean energy further cedes influence over the future global energy system to China. The US is trying to tie its trading partners into fossil fuels, pressing the EU to buy $750 billion of American oil, natural gas, and nuclear technologies during his presidency as part of a trade deal, scuppering an initiative to begin decarbonizing world shipping and pressuring others to reduce their reliance on Chinese technology. But the collapsing cost of solar panels in particular has spoken for itself in many parts of the world. Experts caution that the US's attacks on renewables could cause lasting damage to its competitiveness against China, even if an administration more favorable to renewables were to follow Trump's.

Disney's channels, including ESPN, ABC, FX, and NatGeo, have gone dark on YouTube TV after Google and Disney failed to renew their carriage agreement before the October 30 deadline, with each side blaming the other for using unfair negotiating tactics and price hikes. YouTube TV says it will issue a $20 credit to subscribers if the blackout continues while negotiations proceed. Engadget reports: "Last week Disney used the threat of a blackout on YouTube TV as a negotiating tactic to force deal terms that would raise prices on our customers," YouTube said in an announcement on its blog. "They're now following through on that threat, suspending their content on YouTube TV." YouTube added that Disney's decision harms its subscribers while benefiting its own live TV products, such as Hulu+Live TV and Fubo.

In a statement sent to the Los Angeles Times, however, Disney accused Google's YouTube TV of choosing to deny "subscribers the content they value most by refusing to pay fair rates for [its] channels, including ESPN and ABC." Disney also accused Google of using its market dominance to "eliminate competition and undercut the industry-standard terms" that other pay-TV distributors have agreed to pay for its content.

An anonymous reader shares a report: Is installing Windows 11 with a local account or on unsupported hardware harmful or dangerous? YouTube's AI moderation system seems to think so, as it has started pulling videos that show users how to sidestep Microsoft's setup restrictions.

Tech YouTuber Rich White, aka CyberCPU Tech, was the first to go public about the issue on October 26, when he posted a video reporting the removal of a how-to he published on installing Windows 11 25H2 with a local account instead of a Microsoft account. In the video, White expressed concern that YouTube's automated flagging process may be the root of the problem, as he found it hard to believe that "creating a local account in Windows 11 could lead to serious harm or even death," as YouTube reportedly alleged when it removed the video.

When he appealed, White said that YouTube denied the request within 10 to 20 minutes, early on a Sunday morning, which led him to speculate that there wasn't a human in the loop when the request was shut down. That wasn't his only video removed, either. The next day, White uploaded his video for this week on installing Windows 11 25H2 on unsupported hardware, which was removed hours after being posted. YouTube justified the removal on similar grounds. [...] At least two other YouTubers - Britec09 and Hrutkay Mods - have released videos alleging much of the same.

Trevor McNally posts videos of himself opening locks. The former Marine has 7 million followers and nearly 10 million people watched him open a Proven Industries trailer hitch lock in April using a shim cut from an aluminum can. The Florida company responded by filing a federal lawsuit in May charging McNally with eight offenses. Judge Mary Scriven denied the preliminary injunction request in June and found the video was fair use.

McNally's followers then flooded the company with harassment. Proven dismissed the case in July and asked the court to seal the records. The company had initiated litigation over a video that all parties acknowledged was accurate. ArsTechnica adds: Judging from the number of times the lawsuit talks about 1) ridicule and 2) harassment, it seems like the case quickly became a personal one for Proven's owner and employees, who felt either mocked or threatened. That's understandable, but being mocked is not illegal and should never have led to a lawsuit or a copyright claim. As for online harassment, it remains a serious and unresolved issue, but launching a personal vendetta -- and on pretty flimsy legal grounds -- against McNally himself was patently unwise. (Doubly so given that McNally had a huge following and had already responded to DMCA takedowns by creating further videos on the subject; this wasn't someone who would simply be intimidated by a lawsuit.)

In the end, Proven's lawsuit likely cost the company serious time and cash -- and generated little but bad publicity.

A top United States regulator plans to unveil a faster approach to approving custom gene-editing treatments, a move designed to unleash a wave of industry investment that will yield cures for patients with rare diseases. From a report: Vinay Prasad, who oversees gene therapies at the Food and Drug Administration, said scientific advances, like Crispr, have forced the agency to relax some of its strict rules. As an example, he cited the case of 10-month-old KJ Muldoon, who this year became the first person in history to have his genes custom edited to cure an inherited disease.

"Regulation has to evolve as fast as science evolves," Prasad said in an interview with Bloomberg News. The agency is "going to be extremely flexible and work very fast with the scientists who want to bring these therapies to kids who need it." Prasad plans to publish a paper in early November outlining the FDA's new approach. He predicted it will spark interest in developing treatments for conditions that may affect only a handful of people.

An anonymous reader shares a report: Immigration and Customs Enforcement (ICE) does not let people decline to be scanned by its new facial recognition app, which the agency uses to verify a person's identity and their immigration status, according to an internal Department of Homeland Security (DHS) document obtained by 404 Media. The document also says any face photos taken by the app, called Mobile Fortify, will be stored for 15 years, including those of U.S. citizens.

The document provides new details about the technology behind Mobile Fortify, how the data it collects is processed and stored, and DHS's rationale for using it. On Wednesday 404 Media reported that both ICE and Customs and Border Protection (CBP) are scanning peoples' faces in the streets to verify citizenship.

"ICE does not provide the opportunity for individuals to decline or consent to the collection and use of biometric data/photograph collection," the document, called a Privacy Threshold Analysis (PTA), says. A PTA is a document that DHS creates in the process of deploying new technology or updating existing capabilities. It is supposed to be used by DHS's internal privacy offices to determine and describe the privacy risks of a certain piece of tech. "CBP and ICE Privacy are jointly submitting this new mobile app PTA for the ICE Mobile Fortify Mobile App (Mobile Fortify app), a mobile application developed by CBP and made accessible to ICE agents and officers operating in the field," the document, dated February, reads. 404 Media obtained the document (which you can see here) via a Freedom of Information Act (FOIA) request with CBP.

An anonymous reader shares a report: The International Criminal Court will switch its internal work environment away from Microsoft Office to Open Desk, a European open source alternative, the institution confirmed to Euractiv. The switch comes amid rising concerns about public bodies being reliant on US tech companies to run their services, which have stepped up sharply since the start of US President Donald Trump's second administration.

For the ICC, such concerns are not abstract: Trump has repeatedly lashed out at the court and slapped sanctions on its chief prosecutor, Karim Khan. Earlier this year, the AP also reported that Microsoft had cancelled Khan's email account, a claim the company denies. "We value our relationship with the ICC as a customer and are convinced that nothing impedes our ability to continue providing services to the ICC in the future," a Microsoft spokesperson told Euractiv.

Gallup: After peaking at a record high of 39.9% in 2022, the U.S. adult obesity rate has gradually declined to 37.0% in 2025. This is a statistically meaningful decrease representing an estimated 7.6 million fewer obese adults compared with three years ago. Meanwhile, diagnoses of diabetes -- a lifetime disease that can be managed but not cured -- have now reached an all-time high of 13.8%. Both metrics are part of the ongoing Gallup National Health and Well-Being Index.

[...] Over the past year, more Americans have turned to Type 2 antidiabetic GLP-1 drugs such as semaglutide (brand names Ozempic and Wegovy) for weight loss purposes. The percentage of adults who report taking this class of medicine specifically for weight loss has increased to 12.4%, compared with 5.8% in February 2024 when Gallup first measured it. Usage among women (15.2%) continues to outpace men (9.7%), but both groups have more than doubled their use in the past year. These results dovetail with increased awareness of the drugs used for weight loss, which has risen from 80% to 89% nationally in the same period.

Britain is facing mounting pressure to ban mercury dental fillings, one of the few countries yet to prevent the practice, as new data reveals alarming contamination levels in the nation's fish and shellfish. The Guardian: Mercury is a potent neurotoxin that can harm the nervous, digestive and immune systems, as well as the lungs, kidneys, skin and eyes, even at low levels of exposure. Its organic form, methylmercury, is particularly dangerous to unborn babies and can move through the food chain building up in insects, fish and birds.

Britain is lagging behind the rest of the world on phasing out mercury dental fillings, with 43 countries having already banned mercury amalgam, including the EU, Sweden, Norway, Tanzania, Uganda, Indonesia and the Philippines. Northern Ireland will outlaw mercury fillings from 2035 but no such ban is planned in the rest of Britain. According to new analysis by the Rivers Trust and Wildlife and Countryside Link, more than 98% of fish and mussels tested in English rivers and coastal waters contain mercury above safety limits proposed by the EU, with more than half containing more than five times the recommended safe level.

New submitter hadleyburg writes: President Trump has directed the Department of War to restart nuclear weapons testing. The directive appears to be a counter measure to rival nations catching up with the US. The last US nuclear test was an underground test, on September 23, 1992, in Nevada.

More than a half dozen federal departments and agencies have backed a proposal to ban future sales of the most popular home routers in the United States on the grounds that the vendor's ties to mainland China make them a national security risk, Washington Post reported Thursday, citing people briefed on the matter. From the report: The proposal, which arose from a months-long risk assessment, calls for blocking sales of networking devices from TP-Link Systems of Irvine, California, which was spun off from a China-based company, TP-Link Technologies, but owns some of that company's former assets in China.

The ban was proposed by the Commerce Department and supported this summer by an interagency process that includes the Departments of Homeland Security, Justice and Defense, the people said. "TP-Link vigorously disputes any allegation that its products present national security risks to the United States," Ricca Silverio, a spokeswoman for TP-Link Systems, said in a statement. "TP-Link is a U.S. company committed to supplying high-quality and secure products to the U.S. market and beyond."

If imposed, the ban would be among the largest in consumer history and a possible sign that the East-West divide over tech independence is still deepening amid reports of accelerated Chinese government-supported hacking. Only the legislated ban of Chinese-owned TikTok, which President Donald Trump has averted with executive orders and a pending sale, would impact more U.S. consumers.

Nvidia chief executive Jensen Huang said that maintaining the US edge in AI will require a steady approach that ensures China remains hooked on American technology. From a report: The chipmaker is in an "awkward place" as President Donald Trump prepares to meet with his Chinese counterpart Xi Jinping later this week, Huang told reporters Tuesday at a company conference in Washington. The Nvidia chief praised Trump's commitment to winning but urged careful engagement with China because of the country's massive software developer base and its growing technology capabilities.

During the meeting, Trump and Xi are expected to finalize an agreement to ease trade tensions between the world's two largest economies. When it comes to those negotiations, Huang said he has "no idea" if GPUs -- the chips central to artificial intelligence capabilities -- will be a topic between Trump and Xi.

Huang was careful to leave the negotiating to Trump but encouraged US leadership to think longer term on its overall AI strategy. "A policy that causes America to lose half of the world's developers is not beneficial long-term," Huang said, warning that it was still possible for the US to cede the AI race to China. Keeping US technology in front requires finesse," he said. "It requires balance. It requires long-term thinking."

YouTube says it will automatically upscale videos uploaded below 1080p (full-HD to higher resolution using AI. The Google-owned platform, however, assured that it will give creators and viewers the option to opt out of the enhancement. The feature will apply only to videos uploaded in resolutions from 240p to 720p and will not affect videos that creators have already remastered to 1080p. Creators will retain control over their original files, and viewers will be able to watch videos in their uploaded resolution through a settings option.

YouTube said it plans to support upscaling to 4K in the near future. The company also said it is expanding the video thumbnail size limit from 2MB to 50MB to support 4K images. On videos with tagged products, viewers will soon be able to scan a QR code on TV screens to purchase items directly.

Nvidia became the world's first $5 trillion company on Wednesday after its stock climbed 5% in early Wall Street trading to push its market capitalization to $5.13 trillion. The Silicon Valley chipmaker reached the milestone three months after hitting $4 trillion and three years after it was valued at roughly $400 billion before the debut of ChatGPT.

Nvidia chief executive Jensen Huang said Tuesday that Nvidia had secured half a trillion dollars in orders for its AI chips over the next five quarters. The stock had already gained 5% on Tuesday and added more than $200 billion to its market value. President Donald Trump said Wednesday he planned to discuss Nvidia's Blackwell chip with China's President Xi Jinping when the two leaders meet later this week. Nvidia's latest generation of graphics processing units is not currently available in China because of US export controls. The company's shares have risen more than 85% in the past six months.
