An anonymous reader quotes a report from Popular Mechanics: American composer Alvin Lucier was well-known for his experimental works that tested the boundaries of music and art. A longtime professor at Wesleyan University (before retiring in 2011), Alvin passed away in 2021 at the age of 90. However, that wasn't the end of his lifelong musical odyssey. Earlier this month, at the Art Gallery of Western Australia, a new art installation titled Revivification used Lucier's "brain matter" -- hooked up to an electrode mesh connected to twenty large brass plates -- to create electrical signals that triggered a mallet to strike the varying plates, creating a kind of post-mortem musical piece. Conceptualized in collaboration with Lucier himself before his death, the artists solicited the help of researchers from Harvard Medical School, who grew a mini-brain from Lucier's white blood cells. The team created stem cells from these white blood cells, and due to their pluripotency, the cells developed into cerebral organoids somewhat similar to developing human brains. "At a time when generative AI is calling into question human agency, this project explores the challenges of locating creativity and artistic originality," the team behind Revivification told The Art Newspaper. "Revivification is an attempt to shine light on the sometimes dark possibilities of extending a person's presence beyond the seemed finality of death." "The central question we want people to ask is: could there be a filament of memory that persists through this biological transformation? Can Lucier's creative essence persist beyond his death?" the team said.

OpenAI's latest reasoning models, o3 and o4-mini, hallucinate more frequently than the company's previous AI systems, according to both internal testing and third-party research. On OpenAI's PersonQA benchmark, o3 hallucinated 33% of the time -- double the rate of older models o1 (16%) and o3-mini (14.8%). The o4-mini performed even worse, hallucinating 48% of the time. Nonprofit AI lab Transluce discovered o3 fabricating processes it claimed to use, including running code on a 2021 MacBook Pro "outside of ChatGPT." Stanford adjunct professor Kian Katanforoosh noted his team found o3 frequently generates broken website links. OpenAI says in its technical report that "more research is needed" to understand why hallucinations worsen as reasoning models scale up.

With macOS now 24 years old and Apple officially designating all Intel-based Mac minis as "vintage" or "obsolete," The Register takes a look at new internet tools that help keep vintage Macs online and surprisingly relevant: Cameron Kaiser of Floodgap Systems is a valuable ally. His retro computing interests are broad, and we've mentioned him a few times on The Register, such as his deep dive into the revolutionary Canon Cat computer, and his evaluation of RISC-V hardware performance. Back in 2020, he revived the native Classic Mac OS port of the Lynx web browser, MacLynx. Earlier this month, he came back to it and has updated it again, including adding native Mac OS dialog boxes. His account is -- as usual -- long and detailed but it's an interesting read. He also maintains some other web browsers for elderly Macs, including TenFourFox for Mac OS X 10.4 and Classilla for Mac OS 8.6 and 9.x. If you're not up to git pull commands and elderly Mac OS X build tools, then there is a fork of TenFourFox that may be worth a look, InterWebPPC. It's not current with the new batch of patches, but we can still hope for another build. In other "Classic on the internet" news, although it's not a huge amount of use on its own, there's also a newly released Classic Mac OS version of Mbed-TLS on GitHub. This ports the SSL library -- also used in the super-lightweight Dillo browser -- to the older C89/C90 standard, so that it can build in CodeWarrior and run with OpenTransport from Mac OS 9 right back to later versions of Mac OS 7. Modern macOS is UNIX certified and as such it's not all that dissimilar from other Unix-like OSes, such as Linux and the BSD family. Classic Mac OS is a profoundly different beast, which makes porting modern code to it a complex exercise -- but equally, it's a good learning exercise, and we're delighted to see 21st century programmers exploring this 1980s OS. That may be part of the motivation behind the newly announced and still incomplete SDL 2 "rough draft" that appeared a week ago. It builds on the existing SDL 1.2 port, but so far, it's less complete -- for instance, there's no sound support.

Merged today ahead of the Linux 6.15-rc3 kernel test release on Sunday were the set of "x86 fixes" for the week. Of these x86 fixes are two notable changes in particular...

Bluesky is testing a new verification system featuring blue checks issued by "Trusted Verifiers" like news organizations, rather than a centralized authority or pay-to-play model like X (formerly Twitter). "Looking at the comments on the pull request, it's clear this idea has sparked a lot of discussion and a lot of concern among the community who follow the platform's development closely," reports Neowin. "Many users voiced strong opposition to the change, arguing that the existing domain name verification is sufficient and more aligned with the decentralized ethos that Bluesky aims for." From the report: There's a general worry that adding a visual badge, especially one controlled in part by Bluesky, feels too much like the centralized systems they were trying to escape from by joining Bluesky: "Do not want. BSky is not Twitter 2.0. Do not become like Elon Musk. We came here to get AWAY from that bs." Several commenters also expressed that the current domain name system, while not perfect, is an elegant and decentralized way to build trust, and that adding this new layer feels redundant and gives too much power to centralized entities, including Bluesky itself: "Let's please not do this. Domain names as user IDs is an elegant solution as a system of trust that builds off the infrastructure of an open web." While the majority of the initial reaction seems negative, focusing on concerns about centralization and the value of the existing domain verification, there was some support for the idea of a visual badge, making it easier to quickly identify genuine accounts. One user commented: "I support this change. I like someone to verify that the account is indeed genuine and the username field showing the domain isn't helpful that much... A badge makes it easier to just tick it off that it's genuine." The PR author, estrattonbailey, later added a description to the pull request explaining that the goal is a "stronger visual signal" for notable accounts and clarifying it's not a paid service.

Netflix's Q1 revenue rose to $10.5 billion, a 13% increase from last year, while net income grew to $2.9 billion. The company says it expects more growth in the coming months when it sees "the full quarter benefit from recent price changes and continued growth in membership and advertising revenue." The Verge reports: Netflix raised the prices across most of its plans in January, with its premium plan hitting $24.99 per month. It also increased the price of its Extra Member option -- its solution to password sharing -- to $8.99 per month. Though Netflix already rolled out the increase in the US, UK, and Argentina, the streamer now plans to do the same in France. This is the first quarter that Netflix didn't reveal how many subscribers it gained or lost. It decided to only report "major subscriber milestones" last year, as other streams of revenue continue to grow, like advertising, continue to grow. Netflix last reported having 300 million global subscribers in January. During an earnings call on Thursday, Netflix co-CEO Greg Peters said the company expects to "roughly double" advertising revenue in 2025. The company launched its own advertising technology platform earlier this month. There are some changes coming to Netflix, too, as Peters confirmed that its homepage redesign for its TV app will roll out "later this year." He also hinted at adding an "interactive" search feature using "generative technologies," which sounds a lot like the AI feature Bloomberg reported on last week.

An anonymous reader quotes a report from SecurityWeek: An October 2024 study by Software AG suggests that half of all employees are Shadow AI users, and most of them wouldn't stop even if it was banned. The problem is the ease of access to AI tools, and a work environment that increasingly advocates the use of AI to improve corporate efficiency. It is little wonder that employees seek their own AI tools to improve their personal efficiency and maximize the potential for promotion. It is frictionless, says Michael Marriott, VP of marketing at Harmonic Security. 'Using AI at work feels like second nature for many knowledge workers now. Whether it's summarizing meeting notes, drafting customer emails, exploring code, or creating content, employees are moving fast.' If the official tools aren't easy to access or if they feel too locked down, they'll use whatever's available which is often via an open tab on their browser. There is almost also never any malicious intent (absent, perhaps, the mistaken employment of rogue North Korean IT workers); merely a desire to do and be better. If this involves using unsanctioned AI tools, employees will likely not disclose their actions. The reasons may be complex but combine elements of a reluctance to admit that their efficiency is AI assisted rather than natural, and knowledge that use of personal shadow AI might be discouraged. The result is that enterprises often have little knowledge of the extent of Shadow IT, nor the risks it may present. According to an analysis from Harmonic, ChatGPT is the dominant gen-AI model used by employees, with 45% of data prompts originating from personal accounts (such as Gmail). Image files accounted for 68.3%. The report also notes that 7% of empmloyees were using Chinese AI models like DeepSeek, Baidu Chat and Qwen. "Overall, there has been a slight reduction in sensitive prompt frequency from Q4 2024 (down from 8.5% to 6.7% in Q1 2025)," reports SecurityWeek. "However, there has been a shift in the risk categories that are potentially exposed. Customer data (down from 45.8% to 27.8%), employee data (from 26.8% to 14.3%) and security (6.9% to 2.1%) have all reduced. Conversely, legal and financial data (up from 14.9% to 30.8%) and sensitive code (5.6% to 10.1%) have both increased. PII is a new category introduced in Q1 2025 and was tracked at 14.9%."

Some actors who sold their likenesses to AI video companies like Synthesia now regret the decision, after finding their digital avatars used in misleading, embarrassing, or politically charged content. Ars Technica reports: Among them is a 29-year-old New York-based actor, Adam Coy, who licensed rights to his face and voice to a company called MCM for one year for $1,000 without thinking, "am I crossing a line by doing this?" His partner's mother later found videos where he appeared as a doomsayer predicting disasters, he told the AFP. South Korean actor Simon Lee's AI likeness was similarly used to spook naive Internet users but in a potentially more harmful way. He told the AFP that he was "stunned" to find his AI avatar promoting "questionable health cures on TikTok and Instagram," feeling ashamed to have his face linked to obvious scams. [...] Even a company publicly committed to ethically developing AI avatars and preventing their use in harmful content like Synthesia can't guarantee that its content moderation will catch everything. A British actor, Connor Yeates, told the AFP that his video was "used to promote Ibrahim Traore, the president of Burkina Faso who took power in a coup in 2022" in violation of Synthesia's terms. [...] Yeates was paid about $5,000 for a three-year contract with Synthesia that he signed simply because he doesn't "have rich parents and needed the money." But he likely couldn't have foreseen his face being used for propaganda, as even Synthesia didn't anticipate that outcome. Others may not like their AI avatar videos but consider the financial reward high enough to make up for the sting. Coy confirmed that money motivated his decision, and while he found it "surreal" to be depicted as a con artist selling a dystopian future, that didn't stop him from concluding that "it's decent money for little work." Potentially improving the climate for actors, Synthesia is forming a talent program that it claims will give actors a voice in decision-making about AI avatars. "By involving actors in decision-making processes, we aim to create a culture of mutual respect and continuous improvement," Synthesia's blog said.

IBM is mandating that U.S. sales and Cloud employees return to the office at least three days a week, with work required at designated client sites, flagship offices, or sales hubs. According to The Register, some IBM employees argue that these policies "represent stealth layoffs because older (and presumably more highly compensated) employees tend to be less willing to uproot their lives, and families where applicable, than the 'early professional hires' IBM has been courting at some legal risk." From the report: In a staff memo seen by The Register, Adam Lawrence, general manager for IBM Americas, billed the return-to-office for most stateside sales personnel as a "return to client initiative."Citing how "remarkable it is when our teams work side by side" at IBM's swanky Manhattan flagship office, unveiled in September 2024, Lawrence added IBM is investing in an Austin, Texas, office to be occupied in 2026. Whether US sales staff end up working in NYC, Austin, or some other authorized location, Lawrence told them to brace for -- deep breath -- IBM's "new model" of "effective talent acquisition, deployment, and career progression." We're told that model is "centered on client proximity for those dedicated to specific clients, and anchored on core IBM locations for those dedicated to territories or those in above-market leadership roles." The program requires most IBM US sales staff "to work at least three days a week from the client location where their assigned territory decision-makers work, a flagship office, or a sales hub." Those residing more than 50 miles from their assigned location will be offered relocation benefits to move. Sales hubs are an option only for those with more than one dedicated account. [...] IBM's office policy change reached US Cloud employees in an April 10 memo from Alan Peacock, general manager of IBM Cloud. Peacock set a July 1, 2025, deadline for US Cloud employees to work from an office at least three days per week, with relocating workers given until October 1, 2025. The employee shuffling has been accompanied by rolling layoffs in the US, but hiring in India -- there are at least 10x as many open IBM jobs in India as there are in any other IBM location, according to the corporation's career listings. And earlier this week, IBM said it "is setting up a new software lab in Lucknow," India.

An anonymous reader quotes a report from 404 Media: A judge in Nevada has ruled that "tower dumps" -- the law enforcement practice of grabbing vast troves of private personal data from cell towers -- is unconstitutional. The judge also ruled that the cops could, this one time, still use the evidence they obtained through this unconstitutional search. Cell towers record the location of phones near them about every seven seconds. When the cops request a tower dump, they ask a telecom for the numbers and personal information of every single phone connected to a tower during a set time period. Depending on the area, these tower dumps can return tens of thousands of numbers. Cops have been able to sift through this data to solve crimes. But tower dumps are also a massive privacy violation that flies in the face of the Fourth Amendment, which protects people from unlawful search and seizure. When the cops get a tower dump they're not just searching and seizing the data of a suspected criminal, they're sifting through the information of everyone who was in the location. The ruling stems from a court case involving Cory Spurlock, a Nevada man charged with drug offenses and a murder-for-hire plot. He was implicated through a cellphone tower dump that law enforcement used to place his device near the scenes of the alleged crimes. A federal judge ruled that the tower dump constituted an unconstitutional general search under the Fourth Amendment but declined to suppress the evidence, citing officers' good faith in obtaining a warrant. It marks the first time a court in the Ninth Circuit has ruled on the constitutionality of tower dumps, which in Spurlock's case captured location data from over 1,600 users -- many of whom had no way to opt out.

Netflix Co-CEO Ted Sarandos pushed back on director James Cameron's recent assertion that AI could slash film production costs by half, arguing instead for quality improvements over cost reduction during Netflix's first-quarter earnings call Thursday. "I read the article too about what Jim Cameron said about making movies 50% cheaper," Sarandos said. "I remain convinced that there's an even bigger opportunity to make movies 10% better." Sarandos pointed to Netflix's current AI implementations in set references, pre-visualization, VFX sequence preparation, and shot planning. He said AI-powered tools have democratized high-end visual effects that were once exclusive to big-budget productions. The executive cited 2019's "The Irishman" as a benchmark, noting its "very cutting-edge, very expensive de-aging technology that still had massive limitations." In contrast, he referenced cinematographer Rodrigo Prieto's directorial debut "Pedro Paramo," which employed AI-powered de-aging at "a fraction" of The Irishman's cost. "The entire budget of the film was about what the VFX cost on The Irishman," Sarandos explained. "Same creator using new tools, better tools, to do what was impossible five years ago."

A new Seagate report reveals that hard drives significantly outperform solid-state drives in environmental sustainability metrics, particularly when accounting for manufacturing processes. According to the storage-maker's ""Decarbonizing Data">Decarbonizing Data" [PDF] study, the embodied carbon from manufacturing a 30TB SSD reaches 4,915 kg of CO2 -- approximately 160 times higher than the 29.7 kg produced in creating a comparable hard drive. The analysis measures the full manufacturing footprint, including "upstream extraction, production, transport, bill of material, manufacturing, packaging, and distribution stages" of each technology's lifecycle. When calculated per terabyte annually, the difference remains stark: less than 0.2 kg CO2/TB/year for hard drives versus 32 kg for SSDs. Operational efficiency follows similar patterns, with hard drives consuming 9.6 watts during use versus 20 watts for SSDs, translating to 0.32 and 0.5 watts per terabyte respectively.

Bruce66423 shares a report: Toothpaste can be widely contaminated with lead and other dangerous heavy metals, new research shows. Most of 51 brands of toothpaste tested for lead contained the dangerous heavy metal, including those for children or those marketed as green. The testing, conducted by Lead Safe Mama, also found concerning levels of highly toxic arsenic, mercury and cadmium in many brands. About 90% of toothpastes contained lead, 65% contained arsenic, just under half contained mercury, and one-third had cadmium. Many brands contain a number of the toxins. The highest levels detected violated the state of Washington's limits, but not federal limits. The thresholds have been roundly criticized by public health advocates for not being protective -- no level of exposure to lead is safe, the federal government has found. Bruce66423 asks: "As ever the question that should be asked is: 'What level is worth worrying about and why?'"

An anonymous reader shares a report: Members of the European Parliament were offered special pouches to protect digital devices from espionage and tampering for a visit to Hungary this week, a sign of rising spying fears within Europe. Five lawmakers from the Parliament's civil liberties committee traveled to Hungary on Monday for a three-day visit to inspect the EU member country's progress on democracy, the rule of law and fundamental rights. One lawmaker on the trip confirmed to POLITICO that the Parliament officials joining the delegation were offered Faraday bags -- special metal-lined pouches that block electromagnetic signals -- by the Parliament's services and were also advised to be cautious about using public Wi-Fi networks or charging facilities.

A communication error between GoDaddy Registry and Markmonitor took Zoom's services offline for almost two hours on Wednesday when GoDaddy mistakenly blocked the zoom.us domain. The outage affected all services dependent on the zoom.us domain. GoDaddy's block prevented top-level domain nameservers from maintaining proper DNS records for zoom.us. This created a classic domain resolution failure -- when users attempted to connect to any zoom.us address, their requests couldn't be routed to Zoom's servers because the domain effectively disappeared from the internet's addressing system. Video meetings abruptly terminated mid-session with browser errors indicating the domain couldn't be found. Zoom's status page (status.zoom.us) went offline, hampering communication efforts. Even Zoom's main website at zoom.com failed as the content delivery network couldn't reach backend services hosted on zoom.us servers. Customer support capabilities collapsed when account managers using Zoom's VoIP phones lost connectivity. Resolution required coordinated effort between Zoom, Markmonitor, and GoDaddy to identify and remove the block. After service restoration, users needed to manually flush their DNS caches using command line instructions (including the sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder command for Mac users).

Rice, the world's most consumed grain, will become increasingly toxic as the atmosphere heats and as carbon dioxide emissions rise, potentially putting billions of people at risk of cancers and other diseases, according to new research published this week in The Lancet. From a report: Eaten every day by billions of people and grown across the globe, rice is arguably the planet's most important staple crop, with half the world's population relying on it for the majority of its food needs, especially in developing countries. But the way rice is grown -- mostly submerged in paddies -- and its highly porous texture mean it can absorb unusually high levels of arsenic, a potent carcinogenic toxin that is especially dangerous for babies. After growing rice in controlled fields for six years, researchers from Columbia University and international partners found that when both temperature and CO2 increased in line with climate projections, arsenic levels in rice grains rose significantly. "When we put both of them together, then wow, that was really something we were not expecting," said Lewis Ziska, a plant physiologist at Columbia University who led the study. "You're looking at a crop staple that's consumed by a billion people every day, and any effect on toxicity is going to have a pretty damn large effect." Inorganic arsenic exposure has been linked to cancers, heart disease, and neurological problems in infants. Disease risk rose across all seven top rice-consuming Asian countries analyzed. "This is one more reason to intervene -- to control people's exposure," said co-author Keeve Nachman of Johns Hopkins University. "The No. 1 thing we can do is everything in our power to slow climate change."

Nature has published an analysis of the 21st century's most-cited scientific papers, revealing a surprising pattern: breakthrough discoveries like mRNA vaccines, CRISPR, and gravitational waves don't make the list. Instead, a 2016 Microsoft paper on "deep residual learning" networks claims the top spot, with citations ranging from 103,756 to 254,074 depending on the database. The list overwhelmingly features methodology papers and software tools rather than groundbreaking discoveries. AI research dominates with four papers in the top ten, including Google's 2017 "Attention is all you need" paper that underpins modern language models. The second-most-cited paper -- a 2001 guide for analyzing gene expression data -- was explicitly created to be cited after journal reviewers rejected references to a technical manual. As sociologist Misha Teplitskiy noted, "Scientists say they value methods, theory and empirical discoveries, but in practice the methods get cited more."
