Great Barrier Reef Suffers Worst Coral Decline on Record

Slashdot - 목, 2025/08/07 - 5:50오전
Parts of the Great Barrier Reef have suffered the largest annual decline in coral cover since records began nearly 40 years ago, according to a new report. BBC: Northern and southern branches of the sprawling Australian reef both suffered their most widespread coral bleaching, the Australian Institute of Marine Science (AIMS) found. Reefs have been battered in recent months by tropical cyclones and outbreaks of crown-of-thorns starfish that feast on coral, but heat stress driven by climate change is the predominant reason, AIMS said. AIMS warns the habitat may reach a tipping point where coral cannot recover fast enough between catastrophic events and faces a "volatile" future. AIMS surveyed the health of 124 coral reefs between August 2024 and May 2025. It has been performing surveys since 1986. Often dubbed the world's largest living structure, the Great Barrier Reef is a 2,300km (1,429-mile) expanse of tropical corals that houses a stunning array of biodiversity. Repeated bleaching events are turning vast swaths of once-vibrant coral white. Australia's second largest reef, Ningaloo -- on Australia's western coast -- has also experienced repeated bleaching, and this year both major reefs simultaneously turned white for the first time ever. Coral is vital to the planet. Nicknamed the sea's architect, it builds vast structures that house an estimated 25% of all marine species.

Astronomers Cannot Agree On How Fast the Universe is Expanding

Slashdot - 목, 2025/08/07 - 5:10오전
Two fundamentally different methods for measuring the universe's expansion rate continue to produce incompatible results -- with direct observations of receding galaxies yielding approximately 73 kilometers per second per megaparsec and cosmic microwave background radiation analysis producing closer to 67 km/s/mpc. The discrepancy, known as the Hubble tension, has strengthened annually for the past decadem, according to Duke University astronomer Dan Scolnic. The persistent disagreement prevents calculation of the universe's precise age or size. The Lambda-CDM model, which holds that dark energy and dark matter comprise 95% of the universe while visible matter constitutes just 5%, assumes dark energy's nature has remained constant since the Big Bang. Some theorists propose dark energy's potency changes over time, while others suggest the Milky Way sits within a comparatively empty region of space. A June study using gravitational lensing of quasar light, bypassing traditional distance measurements, matched the higher value. New telescopes including the Vera Rubin Observatory and Nancy Grace Roman Space Telescope may provide additional data. Past improvements in measurement precision have only reinforced rather than resolved the tension.

Sci-Fi Adaptation War of the Worlds Scores 0% on Rotten Tomatoes

Slashdot - 목, 2025/08/07 - 4:34오전
A new War of the Worlds adaptation starring Ice Cube has achieved a 0% critical rating on Rotten Tomatoes after arriving on Prime Video in late July. The science fiction film, produced by Universal Pictures during the 2020 pandemic using actors filming separately through video calls, features alien tripods emerging from meteors to attack Earth. The movie sat unreleased for approximately five years before streaming debut. Critics cite poor visual effects that "wouldn't pass muster on a whimsical Snickers ad" and performances where actors appear to be "performing in a Zoom-style vacuum." The film was shot using screenlife format with most action unfolding on computer screens.

Google Says AI Search Features Haven't Hurt Web Traffic Despite Industry Reports

Slashdot - 목, 2025/08/07 - 3:50오전
Google says total organic click volume from its search engine to websites has remained ""relatively stable year-over-year" despite the introduction of AI Overviews, contradicting third-party reports of dramatic traffic declines. The company reports average click quality has increased, with users less likely to immediately return to search results after clicking through to websites. Google attributes stable traffic patterns to users conducting more searches and asking longer, more complex questions since AI features launched, while AI Overviews display more links per page than traditional results.

Call of Duty's Anti-Cheat Will Require TPM 2.0 and Secure Boot for PC Players

Slashdot - 목, 2025/08/07 - 3:10오전
Activision will require PC players of Call of Duty: Black Ops 7 to enable Trusted Platform Module 2.0 and Windows Secure Boot when the game launches later this year. The company begins testing these anti-cheat measures with Black Ops 6's Season 5 on Thursday without enforcement. TPM 2.0 verifies untampered boot processes while Secure Boot ensures Windows loads only trusted software at startup. Both features perform checks during system and game startup but remain inactive during gameplay. Activision has also pursued legal action against 22 individuals who developed and sold cheats.

Native NVIDIA support for AlmaLinux OS 9 and 10

lwn.net - 목, 2025/08/07 - 2:34오전

The AlmaLinux project has announced the availability of packages to enable native NVIDIA driver support, including CUDA and Secure Boot, for AlmaLinux 9 and 10.

When AlmaLinux started just 5 years ago, this wouldn't have been possible. With NVIDIA's open source version of their graphics drivers things have changed. This open source version is slowly becoming the flagship driver, with new products being added exclusively to it. With the help of some incredible people in the open source ecosystem and the AlmaLinux community, we were able to do something that has yet to be done in the EL ecosystem - ship Secure Boot signed, open source, NVIDIA kernel modules.

Full documentation is available on the AlmaLinux wiki.

A Manhattan jury convicted Tornado Cash co-founder Roman Storm on Wednesday of conspiring to operate an unlicensed money-transfer business, though jurors deadlocked on charges of money laundering conspiracy and sanctions violations after three days of deliberation. Federal prosecutors alleged Storm helped cybercriminals launder more than $1 billion through the cryptocurrency mixing platform, which launched in 2019 as a decentralized protocol designed to obscure transaction origins by pooling and redistributing funds through smart contracts.

Almeida: a brief introduction on how GPU drivers work

lwn.net - 목, 2025/08/07 - 1:16오전
Daniel Almeida continues his look at graphics drivers on the Collabora blog.

The starting point is to understand that a kernel-mode GPU driver connects a much larger UMD (user-mode driver) to the actual GPU. The UMD will actually implement APIs like Vulkan, OpenGL, OpenCL, and others. These APIs, in turn, will be used by actual programs to describe their workload to the GPU. This includes allocating and using not only the geometry and textures, but also the shaders being used to process said data into the final result. This means that a key aspect of GPU drivers is actually allocating GPU memory to house data related to the current scene being drawn so that it can actually be operated on by the hardware.

Google Suffers Data Breach in Ongoing Salesforce Data Theft Attacks

Slashdot - 목, 2025/08/07 - 1:05오전
Google is the latest company to suffer a data breach in an ongoing wave of Salesforce CRM data theft attacks conducted by the ShinyHunters extortion group. BleepingComputer: In June, Google warned that a threat actor they classify as 'UNC6040' is targeting companies' employees in voice phishing (vishing) social engineering attacks to breach Salesforce instances and download customer data. This data is then used to extort companies into paying a ransom to prevent the data from being leaked. In a brief update to the article last night, Google said that it too fell victim to the same attack in June after one of its Salesforce CRM instances was breached and customer data was stolen. "In June, one of Google's corporate Salesforce instances was impacted by similar UNC6040 activity described in this post. Google responded to the activity, performed an impact analysis and began mitigations," reads Google's update.

Trump, Apple To Announce New $100 Billion Commitment To Manufacturing in US

Slashdot - 수, 2025/08/06 - 11:48오후
President Trump and Apple are expected to announce a new $100 billion commitment by Apple to boost manufacturing in the U.S. CBS News: The new investment would increase Apple's commitment to U.S. manufacturing to $600 billion over the next four years, according to a White House official. And it's expected to include a new "American Manufacturing Program" focused on bringing more of Apple's supply chain and advanced manufacturing to the U.S. [...] In May, the president threatened to impose a 25% tariff on iPhones made outside the U.S., writing on Truth Social that he told Cook that he expects that iPhones that will be sold in the U.S. "will be manufactured and built in the United States, not India, or anyplace else."

Nvidia Rejects US Demand For Backdoors in AI Chips

Slashdot - 수, 2025/08/06 - 11:05오후
Nvidia's chief security officer has published a blog post insisting that its GPUs "do not and should not have kill switches and backdoors." From a report: It comes amid pressure from both sides of the Pacific, with some US lawmakers pushing Nvidia to grant the government backdoors to AI chips, while Chinese officials have alleged that they already exist. David Reber Jr.'s post seems pointedly directed at US lawmakers. In May a bipartisan group introduced the Chip Security Act, a bill that would require Nvidia and other manufacturers to include tracking technology to identify when chips are illegally transported internationally, and leaves the door open for further security measures including remote kill switches. While Nvidia is expecting to be granted permits to once again sell certain AI chips in China, its most powerful hardware is still under strict US export controls there and elsewhere.

A kbuild and kconfig maintainer change

lwn.net - 수, 2025/08/06 - 10:41오후
For eight years, Masahiro Yamada has been the sole maintainer of the kernel's build and configuration systems — two complex pieces of infrastructure that many people interact with, but few truly understand. Yamada has just stepped down from that position. Maintenance of the build system will be taken up by Nathan Chancellor and Nicolas Schier (in the "odd fixes" capacity), while the configuration system is now entirely unmaintained.

Thanks are due to Yamada for all that work, and to Chancellor and Schier for stepping up. Hopefully a way will be found to better support these important subsystems in the near future.

Lyft Will Use Chinese Driverless Cars In Britain and Germany

Slashdot - 수, 2025/08/06 - 10:00오후
An anonymous reader quotes a report from the New York Times: China's automakers have teamed up with software companies togo global with their driverless cars, which are poised to claim a big share of a growing market as Western manufacturers are still preparing to compete. The industry in China is expanding despite tariffs imposed last year by the European Union on electric cars, and despite some worries in Europe about the security implications of relying on Chinese suppliers. Baidu, one of China's biggest software companies, said on Monday that it would supply Lyft, an American ride-hailing service, with self-driving cars assembled by Jiangling Motors of China (source paywalled; alternative source). Lyft is expected to begin operating them next year in Germany and Britain, subject to regulatory approval, the companies said. The announcement comes three months after Uber and Momenta, a Chinese autonomous driving company, announced their own plans to begin offering self-driving cars in an unspecified European city early next year. Momenta will soon provide assisted driving technology to the Chinese company IM Motors for its cars sold in Britain. While Momenta has not specified the model that Uber will be using, it has already signaled it will choose a Chinese model. In China, "the pace of development and the pressure to deliver at scale push companies to improve quickly," said Gerhard Steiger, the chairman of Momenta Europe. China's state-controlled banking system has been lending money at low interest rates to the country's electric car industry in a bid for global leadership. [...] Expanding robotaxi services to new cities, not to mention new countries, is not easy. While the individual cars do not have drivers, they typically require one controller for every several cars to handle difficulties and answer questions from users. And the cars often need to be specially programmed for traffic conditions unique to each city. Lyft and Baidu nonetheless said that they had plans for "the fleet scaling to thousands of vehicles across Europe in the following years."

Meta Eavesdropped On Period-Tracker App's Users, Jury Rules

Slashdot - 수, 2025/08/06 - 7:00오후
A San Francisco jury ruled that Meta violated the California Invasion of Privacy Act by collecting sensitive data from users of the Flo period-tracking app without consent. "The plaintiff's lawyers who sued Meta are calling this a 'landmark' victory -- the tech company contends that the jury got it all wrong," reports SFGATE. From the report: The case goes back to 2021, when eight women sued Flo and a group of other tech companies, including Google and Facebook, now known as Meta. The stakes were extremely personal. Flo asked users about their sex lives, mental health and diets, and guided them through menstruation and pregnancy. Then, the women alleged, Flo shared pieces of that data with other companies. The claims were largely based on a 2019 Wall Street Journal story and a 2021 Federal Trade Commission investigation. Google, Flo and the analytics company Flurry, which was also part of the lawsuit, reached settlements with the plaintiffs, as is common in class action lawsuits about tech privacy. But Meta stuck it out through the entire trial and lost. The case against Meta focused on its Facebook software development kit, which Flo added to its app and which is generally used for analytics and advertising services. The women alleged that between June 2016 and February 2019, Flo sent Facebook, through that kit, various records of "Custom App Events" -- such as a user clicking a particular button in the "wanting to get pregnant" section of the app. Their complaint also pointed to Facebook's terms for its business tools, which said the company used so-called "event data" to personalize ads and content. In a 2022 filing (PDF), the tech giant admitted that Flo used Facebook's kit during this period and that the app sent data connected to "App Events." But Meta denied receiving intimate information about users' health. Nonetheless, the jury ruled (PDF) against Meta. Along with the eavesdropping decision, the group determined that Flo's users had a reasonable expectation they weren't being overheard or recorded, as well as ruling that Meta didn't have consent to eavesdrop or record. The unanimous verdict was that the massive company violated the California Invasion of Privacy Act. The jury's ruling could impact over 3.7 million U.S. users who registered between November 2016 and February 2019, with updates to be shared via email and a case website. The exact compensation from the trial or potential settlements remains uncertain.

NASA Satellites That Scientists and Farmers Rely On May Be Destroyed On Purpose

Slashdot - 수, 2025/08/06 - 4:00오후
The Trump administration has reportedly directed NASA to draw up plans to shut down its Orbiting Carbon Observatory satellite missions, which provide vital climate and agricultural data for scientists, oil and gas companies and farmers who need detailed information about carbon dioxide and crop health. As NPR reports, the satellites are "the only two federal satellite missions that were designed and built specifically to monitor planet-warming greenhouse gases." From the report: It is unclear why the Trump administration seeks to end the missions. The equipment in space is state of the art and is expected to function for many more years, according to scientists who worked on the missions. An official review by NASA in 2023 found that "the data are of exceptionally high quality" and recommended continuing the mission for at least three years. Both missions, known as the Orbiting Carbon Observatories, measure carbon dioxide and plant growth around the globe. They use identical measurement devices, but one device is attached to a stand-alone satellite while the other is attached to the International Space Station. The standalone satellite would burn up in the atmosphere if NASA pursued plans to terminate the mission. NASA employees who work on the two missions are making what the agency calls Phase F plans for both carbon-monitoring missions, according to David Crisp, a longtime NASA scientist who designed the instruments and managed the missions until he retired in 2022. Phase F plans lay out options for terminating NASA missions. The OCO missions would lose funding under the Trump Administration's budget proposal for Fiscal Year 2026, which begins Oct. 1 but has yet to pass. "Presidential budget proposals are wish lists that often bear little resemblance to final congressional budgets," notes NPR. "The Orbiting Carbon Observatory missions have already received funding from Congress through the end of the 2025 fiscal year, which ends Sept. 30." "Draft budgets that Congress is currently considering for next year keep NASA funding basically flat. But it's not clear whether these specific missions will receive funding again, or if Congress will pass a budget before current funding expires on Sept. 30."
