Anton Shilov reports via Tom's Hardware: FFmpeg is an open-source video decoding project developed by volunteers who contribute to its codebase, fix bugs, and add new features. The project is led by a small group of core developers and maintainers who oversee its direction and ensure that contributions meet certain standards. They coordinate the project's development and release cycles, merging contributions from other developers. This group of developers tried to implement a handwritten AVX512 assembly code path, something that has rarely been done before, at least not in the video industry. The developers have created an optimized code path using the AVX-512 instruction set to accelerate specific functions within the FFmpeg multimedia processing library. By leveraging AVX-512, they were able to achieve significant performance improvements -- from three to 94 times faster -- compared to standard implementations. AVX-512 enables processing large chunks of data in parallel using 512-bit registers, which can handle up to 16 single-precision FLOPS or 8 double-precision FLOPS in one operation. This optimization is ideal for compute-heavy tasks in general, but in the case of video and image processing in particular. The benchmarking results show that the new handwritten AVX-512 code path performs considerably faster than other implementations, including baseline C code and lower SIMD instruction sets like AVX2 and SSSE3. In some cases, the revamped AVX-512 codepath achieves a speedup of nearly 94 times over the baseline, highlighting the efficiency of hand-optimized assembly code for AVX-512.

An anonymous reader quotes a report from Ars Technica: On Friday, Perplexity launched an election information hub that relies on data from The Associated Press and Democracy Works to provide live updates and information about the 2024 US general election, which takes place on Tuesday, November 5. "Starting Tuesday, we'll be offering live updates on elections using data from The Associated Press so you can stay informed on presidential, senate, and house races at both a state and national level," Perplexity wrote in a blog post. The site will pull data from special data sources (called APIs) hosted by the two organizations. As of Monday, Perplexity's hub currently provides interactive information on voting requirements, poll times, and summaries about ballot measures, candidates, policy positions, and endorsements. Users can ask questions about the information similar to using a chatbot like ChatGPT. Perplexity's embrace of providing election information is an exception in the AI field. Wary about accidentally providing misinformation, competitor AI assistants from OpenAI, Google, and Anthropic currently direct users elsewhere or decline to answer election questions. OpenAI's ChatGPT Search directs election result queries to The Associated Press and Reuters. Perplexity describes its new elections hub as "an entry point for understanding key issues." But like other AI models, Perplexity can produce confabulations (plausible incorrect information) when generating responses. That could present an accuracy problem because the site's Voter Guide service uses AI language models to summarize and interpret information pulled from the web. Here's what Ars Technica advises: "Take what you see on Perplexity's site with a huge grain of salt -- do not rely on it without verifying the information with a trustworthy external source."

An anonymous reader shares a report: With Windows 11 still failing to set the world alight, campaigners are warning that millions of perfectly good PCs could become landfill fodder when support for Windows 10 runs out in eleven and a bit months. Figures compiled by StatCounter show that Windows 11 commanded a 35.55 percent share of the desktop Windows market in October. In comparison, the share of Windows 10 dropped to 60.97 percent, continuing a downward trend that began earlier this year -- it was still at 69.9 percent in April. Unless there is some marked acceleration, Windows 11 is unlikely to dominate the market by the time Microsoft pulls the plug on free updates for most of the Windows 10 world on October 14, 2025.

Singapore plans to boost road capacity by 20,000 vehicles through a new satellite-based road pricing system, the Land Transport Authority (LTA) announced last week. The city-state will replace its current gantry-based Electronic Road Pricing (ERP) system with GPS tracking technology, enabling more precise congestion management without physical toll stations. The Register adds: "ERP 2.0 will provide more comprehensive aggregated traffic information and will be able to operate without physical gantries. We will be able to introduce new 'virtual gantries,' which allow for more flexible and responsive congestion management," explained the LTA. But the island's government doesn't just control inflow into urban areas through toll-like charging -- it also aggressively controls the total number of cars operating within its borders. Singapore requires vehicle owners to bid for a set number of Certificates of Entitlement -- costly operating permits valid for only ten years. The result is an increase of around SG$100,000 ($75,500) every ten years, depending on that year's COE price, on top of a car's usual price. The high total price disincentivizes mass car ownership, which helps the government manage traffic and emissions.

A former teacher has filed a federal lawsuit against PowerSchool, alleging the education technology giant illegally sells student data to third parties without proper consent. Emily Cherkin, lead plaintiff in the class action suit filed in San Francisco, claims PowerSchool has amassed 345 terabytes of data from 440 school districts, including sensitive information about students' health, behavior, and academic records. The company provides software services to more than 60 million students across 90 of the largest U.S. school districts. The lawsuit alleges PowerSchool sells anonymized student data to over 100 partners, including educational consultants and government agencies, while marketing its analytics for workforce and policy planning. The company's Naviance college-planning software alone tracks 6 million high school students. PowerSchool has denied the allegations.

Netflix's gaming division is shifting focus to generative AI weeks after shuttering its premium game studio and laying off 35 developers, the company's newly appointed VP of GenAI for Games has announced. Mike Verdu, previously Vice President of Games, called the move a "once in a generation inflection point" that will "accelerate development" and create novel gaming experiences. The pivot follows the closure of Blue, Netflix's internal studio that had recruited veterans from major franchises including Call of Duty and God of War. "Pay no mind to uninformed speculation," Verdu wrote on LinkedIn, describing recent changes as a "planned transition."

A hardware hacker has successfully modified Nintendo's $100 Alarmo device to run the classic video game Doom, marking another milestone in the gaming community's tradition of porting the 1993 shooter to unconventional devices. YouTuber GaryOderNichts demonstrated the 2.8-inch circular alarm clock running Chocolate Doom natively, using the device's wheel for movement and side buttons for weapons. The hack requires no hardware modifications and works on the current 2.0 software version. The hack came after researchers discovered vulnerabilities in the Alarmo's STM32H7 microcontroller, enabling custom firmware installation through its USB-C port. The trick omits audio due to memory restrictions, GaryOderNichts notes, but it allows for custom animations and displays.

Cybercriminals have breached dozens of major companies including AT&T, Ticketmaster and Hot Topic by exploiting "infostealer" malware that harvests login credentials from infected computers, an investigation has found. The malware, spread through pirated software and social media, has infected 250,000 new devices daily, according to cybersecurity firm Recorded Future. Russian developers create the malware while contractors distribute it globally, deliberately avoiding former Soviet states. Hot Topic suffered potentially the largest retail hack ever in October when attackers accessed 350 million customer records using stolen developer credentials. Google and Microsoft are racing to patch vulnerabilities, but malware makers quickly adapt to new security measures.

App developers Musi and Sarafan Mobile have sued Apple and Google in California federal court over app removals they claim were unjustified, highlighting tensions over the tech giants' intellectual property enforcement policies. Musi's music-streaming app was removed after YouTube complained about interface infringement, while Sarafan's "Reely" app was taken down following Instagram's claims about logo similarity. Both developers say the platforms breached their agreements by removing apps without sufficient evidence. The lawsuits underscore broader concerns about Apple and Google's dominance in app distribution. Their private IP dispute systems operate outside traditional legal frameworks, with platforms making unilateral decisions that can effectively shut down businesses, according to University of New Hampshire law professor Peter Karol. [...] "In a court proceeding, you can see here's a complaint with the allegations, and then we have the defendant respond, and then we have a judge come out with an opinion saying, 'Is the mark valid? Is the mark infringed?'" said Lisa Ramsey, law professor at University of San Diego. Google and Apple's systems, meanwhile, are "a black box."

An anonymous reader shares a report: Another illegal streaming app has made its way to the App Store -- but it only surfaces pirated films for people in certain regions outside the US, including France, Canada, and the Netherlands. As shown in a post on Threads, the App Store listing for "Univer Note" presents itself as a productivity platform that can "easily help you record every day's events and plan your time." However, if you're a user in certain countries, like France or Canada, opening the app shows a collection of pirated movies, such as Venom: The Last Dance, Joker: Folie a Deux, and Terrifier 3.

The clash between law's need for finality and science's evolving nature is creating serious justice problems, an opinion piece on Scientific American argued on Monday. Two recent cases highlight this: Robert Roberson faces execution based on now-discredited shaken baby syndrome science, while the Menendez brothers' life sentences are being questioned due to improved understanding of childhood trauma's effects on violence. Scientific understanding in criminal justice has repeatedly proven wrong. Texas executed Cameron Todd Willingham in 2004 based on invalidated arson science. The FBI found errors in 90% of their reviewed hair analysis cases. Courts still accept bite mark evidence despite experts failing to distinguish human from animal bites. The legal system fails in two critical ways, the story argues: Judges don't properly screen out bad science despite their "gatekeeper" role established in Daubert v. Merrell Dow, and courts resist reopening cases when scientific understanding changes. While some states like Texas and California have laws allowing appeals based on updated science, implementation remains weak. Roberson has spent 20 years on death row and the Menendez brothers 28 years in prison while courts drag their feet on reviewing their cases with current scientific knowledge. The piece argues that constitutional due process requires allowing convicts to challenge their cases when the science underlying their convictions proves faulty. The system can reform by enforcing stricter scientific evidence standards and creating clear paths to challenge convictions based on outdated science.

An anonymous reader shares a report: As world leaders gathered in Colombia this week, they also watched for news from home, where many of the headlines carried the catastrophic consequences of ecological breakdown. Across the Amazon rainforest and Brazil's enormous wetlands, relentless fires had burned more than 22m hectares (55m acres). In Spain, the death toll in communities devastated by flooding passed 200. In the boreal forests that span Siberia, Scandinavia, Alaska and Canada, countries were recording alarming signs that their carbon sinks were collapsing under a combined weight of drought, tree death and logging. As Canada's wildfire season crept to a close, scientists calculated it was the second worst in two decades -- behind only last year's burn, which released more carbon than some of the world's largest emitting countries. In global negotiations, climate and nature move along two independent tracks, and for years were broadly treated as distinct challenges. But as negotiations closed at the Cop16 biodiversity summit in Cali on Saturday, ministers from around the world underscored the crucial importance of nature to limiting damage from global heating, and vice versa -- emphasising that climate and biodiversity could no longer be treated as independent issues if either crisis was to be resolved. Countries agreed a text on links between the climate and nature, but failed to include language on a phase out of fossil fuels. The UK environment secretary, Steve Reed, said that attending the summit in Colombia had brought home the links between climate and biodiversity. "One of the other things that's really struck me coming here and speaking to the Colombians in particular is how for them the nature crisis and the climate crisis are exactly the same thing. In the UK, perhaps more widely in the global north, we tend to talk a lot about climate and particularly net zero, and much less about nature -- perhaps because we're already more nature-depleted. But those two things connect entirely," he said. The Cop16 president, Susana Muhamad, Colombia's environment minister, has sought to put nature on a level with global efforts to decarbonise the world economy during the summit, warning that slashes to greenhouse gas emissions must be accompanied by the protection and restoration of the natural world if they are to be effective. Her presidency has repeatedly described nature and climate as "two sides of the same coin."

Apple has scrapped plans for a budget mixed-reality headset initially slated for 2025, pushing the launch to 2027, according to supply chain analyst Ming-Chi Kuo. The company will instead focus on releasing an upgraded Vision Pro next year featuring its M5 chip and enhanced AI capabilities, he said. The canceled lower-cost model would have stripped features like EyeSight and used cheaper components to target mainstream consumers.

An anonymous reader shares a report: Plans by Mark Zuckerberg's Meta to build an AI data centre in the US that runs on nuclear power were thwarted in part because a rare species of bee was discovered on land earmarked for the project, according to people familiar with the matter. Zuckerberg had planned to strike a deal with an existing nuclear power plant operator to provide emissions-free electricity for a new data centre supporting his artificial intelligence ambitions. However, the potential deal faced multiple complications including environmental and regulatory challenges, these people said. The discovery of the rare bee species on a location next to the plant where the data centre was to be built would have complicated the project, Zuckerberg told a Meta all-hands meeting last week, according to two people familiar with the meeting.

An anonymous reader shared this report from the Los Angeles Times: Los Angeles County has filed suit against the world's largest beverage companies — Coca-Cola and Pepsi — claiming the soda and drink makers lied to the public about the effectiveness of plastic recycling and, as a result, left county residents and ecosystems choking in discarded plastic... The Los Angeles County suit alleges — in a vein similar to that of [California attorney general] Bonta's suit against Exxon Mobil — that the global beverage companies misrepresented the environmental impact of their plastic bottles, "despite knowing that plastics cannot be readily disposed of without associated environmental impacts." "Coke and Pepsi need to stop the deception and take responsibility for the plastic pollution problems" their products are causing, said Los Angeles County Board of Supervisors Chair Lindsey P. Horvath... Currently, just 9% of the world's plastics are recycled. The rest ends up being incinerated, sent to landfills, or discarded on the landscape, where they are often flushed into rivers or out to sea. At the same time, there is growing concern about the health and environmental consequences of microplastics — the bits of degraded plastic that slough off as the product ages, or is used, or washed. The tiny particles have been detected in every ecosystem on the planet that has been surveyed, as well as nearly every living organism examined... According to the county's statement, the two companies have consistently ranked as the world's "top plastic polluters...." The beverage maker lawsuit was filed in Los Angeles Superior Court by County Counsel Dawyn R. Harrison on behalf of the people of the state of California... "The goal of this lawsuit is to stop the unfair and illegal conduct, to address the marketing practices that deceive consumers, and to force these businesses to change their practices to reduce the plastic pollution problem in the County and in California," Harrison said in a statement. "My office is committed to protecting the public from deceptive business practices and holding these companies accountable for their role in the plastic pollution crisis."

Five years ago remote workers were offered $10,0000 to move to Tulsa, Oklahoma for at least a year. Since then roughly 3,300 have accepted the offer, according to the New York TImes. [Alternate URL here.] But more importantly, now researchers are looking at the results: Their research, released this month, surveyed 1,248 people — including 411 who had participated in Tulsa Remote and others who were accepted but didn't move or weren't accepted but had applied to the program — and found that remote workers who moved to Tulsa saved an average of $25,000 more on annual housing costs than the group that was chosen but didn't move... Nearly three-quarters of participants who have completed the program are still living in Tulsa. The program brings them together for farm-to-table dinners, movie nights and local celebrity lectures to help build community, given that none have offices to commute to. The article says every year the remote workers contribute $14.9 million in state income taxes and $5.8 million in sales taxes (more than offsetting the $33 million spent over the last five years). And additional benefits could be even greater. "We know that for every dollar we've spent on the incentive, there's been about a $13 return on that investment to the city," the program's managing director told Fortune — pointing out that the remote workers have an average salary of $100,000. (500 of the 3,300 even bought homes...) The Tulsa-based George Kaiser Family Foundation — which provides the $10,000 awards — told the New York Times it will continue funding the program "so long as it demonstrates to be a community-enhancing opportunity." And with so much of the population now able to work remotely, the lead author on the latest study adds that "Every heartland mayor should pay attention to this..."

GitHub released its annual "State of the Octoverse" report this week. And while "Systems programming languages, like Rust, are also on the rise... Python, JavaScript, TypeScript, and Java remain the most widely used languages on GitHub." In fact, "In 2024, Python overtook JavaScript as the most popular language on GitHub." They also report usage of Jupyter Notebooks "skyrocketed" with a 92% jump in usage, which along with Python's rise seems to underscore "the surge in data science and machine learning on GitHub..." We're also seeing increased interest in AI agents and smaller models that require less computational power, reflecting a shift across the industry as more people focus on new use cases for AI... While the United States leads in contributions to generative AI projects on GitHub, we see more absolute activity outside the United States. In 2024, there was a 59% surge in the number of contributions to generative AI projects on GitHub and a 98% increase in the number of projects overall — and many of those contributions came from places like India, Germany, Japan, and Singapore... Notable growth is occurring in India, which is expected to have the world's largest developer population on GitHub by 2028, as well as across Africa and Latin America... [W]e have seen greater growth outside the United States every year since 2013 — and that trend has sped up over the past few years. Last year they'd projected India would have the most developers on GitHub #1 by 2027, but now believe it will happen a year later. This year's top 10? 1. United States 2. India 3. China 4. Brazil 5. United Kingdom 6. Russia 7. Germany 8. Indonesia 9. Japan 10. Canada Interestingly, the UK's population ranks #21 among countries of the world, while Germany ranks #19, and Canada ranks #36.) GitHub's announcement argues the rise of non-English, high-population regions "is notable given that it is happening at the same time as the proliferation of generative AI tools, which are increasingly enabling developers to engage with code in their natural language." And they offer one more data point: GitHub's For Good First Issue is a curated list of Digital Public Goods that need contributors, connecting those projects with people who want to address a societal challenge and promote sustainable development... Significantly, 34% of contributors to the top 10 For Good Issue projects... made their first contribution after signing up for GitHub Copilot. There's now 518 million projects on GitHub — with a year-over-year growth of 25%...

The Atlantic complains that our chaos of different plug types "was supposed to end, with USB-C as our savior." But part of the problem is what they call "the second circle of our cable hell: My USB-C may not be the same as yours. And the USB-C you bought two years ago may not be the same as the one you got today. And that means it might not do what you now assume it can." A lack of standardization is not the problem here. The industry has designed, named, and rolled out a parade of standards that pertain to USB and all its cousins. Some of those standards live inside other standards. For example, USB 3.2 Gen 1 is also known as USB 3.0, even though it's numbered 3.2. (What? Yes.) And both of these might be applied to cables with USB-A connectors, or USB-B, or USB-Micro B, or — why not? — USB-C. The variations stretch on and on toward the horizon. Hope persists that someday, eventually, this hell can be escaped — and that, given sufficient standardization, regulatory intervention, and consumer demand, a winner will emerge in the battle of the plugs. But the dream of having a universal cable is always and forever doomed, because cables, like humankind itself, are subject to the curse of time, the most brutal standard of them all. At any given moment, people use devices they bought last week alongside those they've owned for years; they use the old plugs in rental cars or airport-gate-lounge seats; they buy new gadgets with even better capabilities that demand new and different (if similar-looking) cables. Even if Apple puts a USB-C port in every new device, and so does every other manufacturer, that doesn't mean that they will do everything you will expect cables to do in the future. Inevitably, you will find yourself needing new ones. Back in 1998, the New York Times told me, "If you make your move to U.S.B. now, you can be sure that your new devices will have a port to plug into." I was ready! I'm still ready. But alas, a port to plug into has never been enough. Obligatory XKCD.

Our bodies divest themselves of 60 billion cells every day through a natural process called "apoptosis". So Stanford medicine researchers are developing a new approach to cancer therapy that could "trick cancer cells into disposing of themselves," according to announcement from Stanford's medical school: Their method accomplishes this by artificially bringing together two proteins in such a way that the new compound switches on a set of cell death genes... One of these proteins, BCL6, when mutated, drives the blood cancer known as diffuse large cell B-cell lymphoma... [It] sits on DNA near apoptosis-promoting genes and keeps them switched off, helping the cancer cells retain their signature immortality. The researchers developed a molecule that tethers BCL6 to a protein known as CDK9, which acts as an enzyme that catalyzes gene activation, in this case, switching on the set of apoptosis genes that BCL6 normally keeps off. "The idea is, Can you turn a cancer dependency into a cancer-killing signal?" asked Nathanael Gray, PhD, co-senior author with Crabtree, the Krishnan-Shah Family Professor and a chemical and systems biology professor. "You take something that the cancer is addicted to for its survival and you flip the script and make that be the very thing that kills it...." When the team tested the molecule in diffuse large cell B-cell lymphoma cells in the lab, they found that it indeed killed the cancer cells with high potency. They also tested the molecule in healthy mice and found no obvious toxic side effects, even though the molecule killed off a specific category of of the animals' healthy B cells, a kind of immune cell, which also depend on BCL6. They're now testing the compound in mice with diffuse large B-cell lymphoma to gauge its ability to kill cancer in a living animal. Because the technique relies on the cells' natural supply of BCL6 and CDK9 proteins, it seems to be very specific for the lymphoma cells — the BCL6 protein is found only in this kind of lymphoma cell and in one specific kind of B cell. The researchers tested the molecule in 859 different kinds of cancer cells in the lab; the chimeric compound killed only diffuse large cell B-cell lymphoma cells. Scientists have been trying to shut down cancer-driving proteins, one of the researchers says, but instead, "we're trying to use them to turn signaling on that, we hope, will prove beneficial for treatment." The two researchers have co-founded the biotech startup Shenandoah Therapeutics, which "aims to further test this molecule and a similar, previously developed molecule," according to the article, "in hopes of gathering enough pre-clinical data to support launching clinical trials of the compounds. "They also plan to build similar molecules that could target other cancer-driving proteins..."

Long-time Slashdot reader schwit1 shared this report from the blog Interesting Engineering: A team of students made history this month by performing Europe's first rocket hop test. Those who have followed SpaceX's trajectory will know hop tests are a vital stepping stone for a reusable rocket program, as they allow engineers to test their rocket's landing capabilities. Impressively, no private company or space agency in Europe had ever performed a rocket hop test before. Essentially, a group of students performed one of the most important rocket tests in the history of European rocketry. However, the remarkable nature of this story doesn't end there. Amazingly, the whole thing was almost derailed by a piece of cheese. A slice of Gruyère the team strapped to their rocket's landing legs almost caused the rocket to spin out of control. Thankfully, disaster was averted, and the historic hopper didn't end up as rocket de-Brie.
