The Rust Foundation Wants to Improve Rust and C++ Interoperability

Par : EditorDavid
18 novembre 2024 à 12:34
The goal? "Make C++ and Rust interoperability easily accessible and approachable to the widest possible audience." And the Rust Foundation's "Interop Initiative" is specifically focused on the goal of interoperability "within the same executable," through either inline embedding that allows "integrated compilation", or foreign function interfaces. To that end, a statement addressing "the challenges and opportunities in C++ and Rust interoperability" was announced this week by the Rust Foundation. Pointing out that the "Interop Initiative" was launched in February 2024 with a $1M contribution from Google, it now "proposes a collaborative, problem-space approach engaging key stakeholders from both language communities. "Rather than prescribing specific solutions, this problem statement serves as a foundation for community input and participation in shaping both the strategic direction and tactical implementation of improved C++/Rust interoperability." Their official problem statement outlines three "key strategic approaches." - Improve existing tools and address tactical issues to reduce interoperability friction and risk in the short term. - Build consensus around long-term goals requiring changes to Rust itself and develop the tactical approaches to begin pursuing them. - Engage with the C++ community and committee to improve the quality of interoperation for both languages to help realize the mutual goals of safety and performance. And it argues that interoperability "is essential to pursuing safety and performance which is maintainable and scalable." A significant amount of development has gone into libraries to facilitate interoperability with both C and C++, but from the language and compiler level, the situation remains largely unchanged from the early days of Rust. As the desire to integrate Rust into more C++ codebases increases, the value of making C++/Rust interoperability safer, easier, and more efficient is rapidly increasing. While each language takes a different overall approach, both view safety as an essential concern in modern systems. Both Rust and C++ have language- and standard-library-level facilities to improve safety in seemingly compatible ways, but significant benefits are lost when transiting the foreign function interfaces (FFI) boundary using the C ABI... The consequence of this increased cost to interoperate means both C++ and Rust codebases are less able to access valuable code that already exists in the other language, and the ability to transition system components from one language to another is reduced outside of existing C-like interface boundaries. Ultimately, this reduction in freedom leads to worse outcomes for all users since technologists are less free to choose the most effective solutions.

ChatGPT-4 Beat Doctors at Diagnosing Illness, Study Finds

Par : EditorDavid
18 novembre 2024 à 09:04
Dr. Adam Rodman, a Boston-based internal medicine expert, helped design a study testing 50 licensed physicians to see whether ChatGPT improved their diagnoses, reports the New York TImes. The results? "Doctors who were given ChatGPT-4 along with conventional resources did only slightly better than doctors who did not have access to the bot. "And, to the researchers' surprise, ChatGPT alone outperformed the doctors." [ChatGPT-4] scored an average of 90 percent when diagnosing a medical condition from a case report and explaining its reasoning. Doctors randomly assigned to use the chatbot got an average score of 76 percent. Those randomly assigned not to use it had an average score of 74 percent. The study showed more than just the chatbot's superior performance. It unveiled doctors' sometimes unwavering belief in a diagnosis they made, even when a chatbot potentially suggests a better one. And the study illustrated that while doctors are being exposed to the tools of artificial intelligence for their work, few know how to exploit the abilities of chatbots. As a result, they failed to take advantage of A.I. systems' ability to solve complex diagnostic problems and offer explanations for their diagnoses. A.I. systems should be "doctor extenders," Dr. Rodman said, offering valuable second opinions on diagnoses. "The results were similar across subgroups of different training levels and experience with the chatbot," the study concludes. "These results suggest that access alone to LLMs will not improve overall physician diagnostic reasoning in practice. "These findings are particularly relevant now that many health systems offer Health Insurance Portability and Accountability Act-compliant chatbots that physicians can use in clinical settings, often with no to minimal training on how to use these tools."

On 15th Anniversary, Go Programming Languages Rises in Popularity

Par : EditorDavid
18 novembre 2024 à 06:19
The Tiobe index tries to track the popularity of programming languages by counting the number of search results for the language's name followed by the word "programming" (on 25 different search engines). And this month there were some surprises... By TIOBE's reckoning, compared to a year ago PHP has now fallen from #7 to #12, while Delphi/Object Pascal shot up five spots from #16 to #11. In that same year, Fortran jumped from #12 to #8 — while both Visual Basic and SQL dropped down a single rank. Toward the top of the list, C actually fell from the #2 spot over the last 12 months to the #4 spot. And Go just reached the #7 rank on the TIOBE's ranking of programming language popularity — "an all time high for Go," according to TIOBE CEO Paul Jansen. In this month's note, he explains what he thinks is unusual about this — starting by saying that Go programs are both fast, and easy in many ways — easy to deploy, easy to learn, and easy to understand. Python for instance is easy to learn but not fast, and deployment for larger Python programs is fragile due to dependencies on all kind of versioned libraries in the environment. If compared to Rust for instance (another contender for a top position), Go is a tiny bit slower, but the Go programs are much easier to understand. The next hurdle for Go in the TIOBE index is JavaScript at position #6. That will be a tough one to pass. JavaScript is ubiquitous in software development, although for larger JavaScript systems we see a shift to TypeScript nowadays. "If annual trends continue this way, Go will bypass JavaScript within 3 years," TIOBE's CEO predicts. (Adding "Let's see what the future has in store for Go...") Although the Go team actually has specific plans for the future, according to a blog post this week celebrating Go's 15th anniversary: We're working on making Go better for AI — and AI better for Go — by enhancing Go's capabilities in AI infrastructure, applications, and developer assistance. Go is a great language for building production systems, and we want it to be a great language for building production AI systems, too... For AI applications, we will continue building out first-class support for Go in popular AI SDKs, including LangChainGo and Genkit. And from its very beginning, Go aimed to improve the end-to-end software engineering process, so naturally we're looking at bringing the latest tools and techniques from AI to bear on reducing developer toil, leaving more time for the fun stuff — like actually programming! TIOBE's top 10 programming language rankings for the month of November: Python C++ Java C C# JavaScript Go Fortran Visual Basic SQL

New Dune Prequel 'Dune: Prophecy' Premieres on HBO and Max

Par : EditorDavid
18 novembre 2024 à 02:47
A new six-episode Dune series premiers tonight on HBO and Max — a prequel to the Denis Villeneuve-directed Dune movies set 10,000 years before the birth f Paul Atreides. The Hollywood Reporter writes that it "draws on source material from the 2012 novel Sisterhood of Dune by Brian Herbert and Kevin J. Anderson, and Frank Herbert's 1965 novel Dune, the origin of the Dune universe." Cord-cutters can stream Dune: Prophecy online without cable on Max, with subscriptions starting at $9.99 per month through both Prime Video and the Max website directly. Amazon offers a seven-day free trial to the Max channel. Those who want to watch Dune: Prophecy online without a traditional cable service can also get Max as an add-on to existing streaming services, including Hulu and DirecTV Stream. The San Francisco Chronicle describes the series as "">all palace intrigues, agonizing deaths and magical mind games." Taking a further cue from the network's top-rated Game of Thrones, this show indulges more sex and nudity than the Dune movies allow. It could be argued that elements like this introduce a liveliness often missing from the portentous big-screen behemoths, marking an improvement. Another fun touch here: Many characters are constantly baked. Set a millennium before Frank Herbert's novels and the films' events, and a century after humans overthrew their "thinking machine" overlords, the psychoactive "Spice" from the desert planet Arrakis is already the most valued substance in the universe. It's not only vital for spaceship navigation and to expand the mental powers of sorceressy sisterhoods like the Bene Gesserit, it's the club drug of choice for younger members of the galaxy-ruling Great Houses. As ever with "Dune" business, control of the Spice trade fuels much of the conflict and character motivations. Of which there are just enough to keep things interesting without becoming confusing... While the show can't match the outsize visual scope of Denis Villeneuve's films, it does pleasingly approximate those vast alien landscapes, Brutalist edifices and high-ceilinged chambers on a TV budget. For those who find Villeneuve's formal gigantism oppressive, the series' more human scale might be another welcome change of pace... There may not be an original thought in this "Dune" product's Spice-soaked head, but it is one professionally put-together piece of this sort of entertainment. "Tasked with making more material with less money and time, Prophecy cannot hope to equal Villeneuve's aesthetic accomplishments," writes Variety. "But at its best, the show does justice to the intricate politics and ethical debates that form a cornerstone of Frank Herbert's fictional universe... The primary Dune plot finds many echoes throughout Prophecy..." On the other hand, Vulture argues the six-episode series is "stuck in prequel quicksand," even calling it "an act of cowardice and abdication of creativity" (while also noting moments where it "feels like it's stretching itself to be something other than what we expect..."

Linux Kernel 6.12 Has Been Released

Par : EditorDavid
18 novembre 2024 à 01:45
Slashdot unixbhaskar writes: Linus has released a fresh Linux kernel for public consumption. Please give it a try and report any glitches to the maintainers for improvement. Also, please do not forget to express your appreciation to those tireless folks who did all the hard work for you. The blog OMG Ubuntu calls it "one of the most biggest kernel releases for a while," joking that it's a "really real-time kernel." The headline feature in Linux 6.12 is mainline support for PREEMPT_RT. This patch set dramatically improves the performance of real-time applications by making kernel processes pre-emptible — effectively enabled proper real-time computing... Meanwhile, Linus Torvalds himself contributes a new method for user-space address masking designed to claw back some of the performance lost due to Spectre-v1 mitigations. You might have heard that kernel devs have been working to add QR error codes to Linux's kernel panic BSOD screen (as a waterfall of error text is often cut off and not easily copied for ad-hoc debugging). Well, Linux 6.12 adds support for those during Direct Rendering Manager panics... A slew of new RISC-V CPU ISA extensions are supported in Linux 6.12; hybrid CPU scaling in the Intel P-State driver lands ahead of upcoming Intel Core Ultra 2000 chips; and AMD P-State driver improves AMD Boost and AMD Preferred Core features. More coverage from the blog 9to5Linux highlights a new scheduler called sched_ext, Clang support (including LTO) for nolibc, support for NVIDIA's virtual command queue implementation for SMMUv3, and "an updated cpuidle tool that now displays the residency value of cpuidle states for a clearer and more detailed view of idle state information when using cpuidle-info." Linux kernel 6.12 also introduces SWIG bindings for libcpupower to make it easier for developers to write scripts that use and extend the functionality of libcpupower, support for translating normalized error addresses reported by an AMD memory controller into system physical addresses using a UEFI mechanism called platform runtime mechanism (PRM), as well as simplified loading of microcode patches on AMD Zen and newer CPUs by using the family, model, and stepping encoded in the patch revision number... Moreover, Linux 6.12 adds support for running as a protected guest on Android as well as perf and support for a bunch of new interconnect PMUs. It also adds the final conversions to the new Intel VFM CPU model matching macros, rewrites the PCM buffer allocation handling and locking optimizations, and improves the USB audio driver...

Google, Microsoft Are Spending Massively on AI, Quarterly Earnings Show

Par : EditorDavid
18 novembre 2024 à 00:26
This week Alphabet CEO Sundar Picahi assured investors that their long-term AI focus and investment (and a "commitment to innovation") "are paying off," reports the Associated Press. Alphabet's stock has already soared 20% this year, and it's "still thriving" as the company "navigates through a pivotal shift to AI and battles regulators..." Alphabet earned $26.3 billion, or $2.12 per share during the most recent quarter, a 34% increase from a year ago. Revenue rose 15% from the same time last year to $88.27 billion... The profits would have been even higher if Google wasn't pouring so much money into building up its AI arsenal in a technological arms race that includes other industry heavyweights Microsoft, Amazon, Apple, Facebook parent Meta Platforms and rising star OpenAI. The AI investments are the primary reason Google's capital expenditures in the past quarter soared 62% from the same time last year to $13.1 billion. The AI spending will likely stay at roughly the same level during the current October-December period, and the rise even higher next year, according to Anat Ashkenazi, Alphabet's chief financial officer. But Ashkenazi also emphasized the Mountain View, California, company will act on cost-cutting opportunities in other areas to help boost profits. Alphabet already has trimmed its payroll from more than 190,000 worldwide employees early last year to about 181,000 workers now. In an example of how AI can perform tasks that once required human brainpower, Pichai said the technology is now writing more than 25% of the company's new computer coding. After the results, investors sent Alphabet's stock price up 5% in extended trading, the article points out. "Both Alphabet's profit and revenue increased at a brisker pace than industry analysts anticipated, thanks primarily to a moneymaking machine powered by Google's ubiquitous search engine... [Google's digital search-engine ads earned $49.39 billion, 12% more than the same quarter of 2023.] And Google's cloud division is growing at an even more robust rate, thanks to demand for AI services. The cloud division generated $11.35 billion in revenue during the past quarter, a 35% increase from last year." And meanwhile over at Microsoft, quarterly sales surged 16% to $65.6 billion, reports the Associated Press. But again, "the company sought to assure investors its huge spending on artificial intelligence is paying off." The company has spent billions of dollars to expand its global network of data centers and other physical infrastructure required to develop AI technology... As a result, AI-related products are now on track to contribute about $10 billion to the company's annual revenue, the "fastest business in our history to reach this milestone," CEO Satya Nadella said on a call with analysts Wednesday. [Though Microsoft "hasn't yet formally reported revenue specifically from AI products," the article notes later, with Microsoft instead saying it's infused AI and Copilot into all its business segments.] Just in the last quarter, Microsoft spent $20 billion "mostly for its cloud computing and AI needs," the article points out. But there's still making plenty of money... The software maker also reported an 11% increase in quarterly profit to $24.7 billion, or $3.30 per share, which beat Wall Street expectations for the July-September period... Leading in sales for the quarter was Microsoft's productivity business segment, which includes its Office suite of email and other workplace products, growing 12% to $28.3 billion. Microsoft's cloud-focused business segment grew 20% from the same time last year to $24.1 billion for the three months ending Sept. 30. Its personal computing business, led by its Windows division, grew 17% to $13.2 billion. A big part of that growth came from Microsoft's Xbox video game business, which was boosted by its purchase of game publishing giant Activision Blizzard a year ago.

What Happened When a Washington County Tried a 32-Hour Workweek?

Par : EditorDavid
17 novembre 2024 à 22:52
On a small network of islands north of Seattle, Washington, San Juan County just completed its first full year of 32-hour workweeks, reports CNN. And Tuesday the county released a report touting "a host of positive outcomes — from recruiting to retention to employee happiness — and a cost savings of more than $975,000 compared to what the county would have paid if it met the union's pay increase demands." The county said the 32-hour workweek has attracted a host of new talent: Applications have spiked 85.5% and open positions are being filled 23.75% faster, while more employees are staying in their jobs — separation (employees quitting or retiring) dropped by 48%. And 84% of employees said their work-life balance was better. "This is meeting many of the goals that we set out to do when we implemented it," County Manager Jessica Hudson said. said, noting the county is looking for opportunities to expand the initiative... Departments across San Juan County have implemented the 32-hour workweek differently, some staggering staffing to maintain their previous availability to the public while others have shortened schedules to be open just four days a week... "I tell people, you're not going to see things change from your perspective," said Joe Ingman, a park manager in the county. "Offices are going to stay open, bathrooms are going to get cleaned, grass is going to get mowed." His department adjusted schedules to stay staffed seven days a week, and while communication across shifts was an initial hurdle, issues were quickly ironed out. "It was probably the smoothest summer I've had, and I've been working in parks for over a decade," he said, crediting the new schedule as a boon for recruiting. While job postings used to languish unfilled for months, last summer the applicant pool was not only bigger but more qualified, and the two staffers he hired both cited coming to the county because of the 32-hour workweek. "It's no more cost to the public to work 32 hours — but we have better applicants," he said. Ingman also said the four-day workweek has done wonders for his job satisfaction; he'd watched colleagues burn out for years, but now sees a path for his own future in the department... County employees have used their extra time off to spend less money on childcare, volunteer in their kids' schools, and contribute to the community... While San Juan County's motivation in adopting a shortened workweek was financial, the benefits its employees cite speak to a larger trend, as workplaces around the country increasingly explore flexible schedules to combat burnout and attract and retain talent. A survey of CEOs this spring found nearly one third of large US companies were looking into solutions like four-day or four-and-a-half-day workweeks... Even without a reduction in total hours, a Gallup poll last year found a third day off would be widely embraced: 77% of US workers said a 4-day, 40-hour workweek would have a positive impact on their wellbeing. One worker shared their thoughts with CNN. "Life shouldn't be about just working yourself into the ground..." And they added that "So far, I feel happy; I feel seen as an employee and as a human, and I feel like it could be a beautiful step forward for other people if we just trust it and try it." They even had some advice for other employers. "Change happens by somebody actually doing the change. The only way we're going to find out if it works is by doing."

Privately-Funded EU Company Raises $160M for SpaceX Dragon-Like Reusable Space Capsule

Par : EditorDavid
17 novembre 2024 à 21:02
Nyx is a new reusable space capsule that "safely and affordably carries cargo to and from space stations," according to the web page of its European-based manufacturer, The Exploration Company, "launching from any heavy launcher worldwide." And the company "just closed a large funding round to further its mission of building Europe's first reusable space capsule," reports TechCrunch — pointing out that right now, "Only two companies currently provide cargo delivery to and from the International Space Station, and both are based in the United States." The $160 million Series B round will fund the continued development of the Nyx spacecraft, which will be capable of carrying 3,000 kilograms of cargo to and from Earth. The company, which was founded three years ago by aerospace engineers Hélène Huby, Sebastien Reichstat, and Pierre Vine, is aiming to conduct Nyx's maiden flight to and from the International Space Station in 2028. "We are the first company in the world where this is for the first time mainly funded by private investors," Huby said in a recent interview. This is in contrast to SpaceX's Dragon capsule, which she said was "mainly funded by NASA." The new funding, which was led by Balderton Capital and Plural, brings the startup's total funding to date to over $208 million. The Series B also included participation from Bessemer Venture Partners, NGP Capital, and two sovereign European funds, French Tech Souveraineté and DeepTech & Climate Fonds. "We've been able to deliver on promises in the past three years," Huby said. "We've been able to meet our cash target ever quarter ... The investors, they could see that we basically can deliver on time, on cost, on quality." The startup has made traction with the European Space Agency, which has recognized the need to foster native space launch and transportation capabilities... It's a promising start, but equally promising is the traction The Exploration Company is seeing on the commercial side. Around 90% of the startup's $770 million contract backlog has come from private station developers Vast, Axiom Space, and Starlab, according to recent reporting... The second sub-scale demonstrator mission, called Mission Possible, is scheduled to launch on a SpaceX Falcon 9 next year. TechCrunch quotes Huby as saying "I highly respect what SpaceX has been able to achieve.We are trying to learn as much as possible from that, we are inspired by what they have achieved." In a CNBC interview, Huby says "It's a big market, and it's growing about a bit more than 10% per year because more nations want to fly their astronauts and more nations want to go to the moon. So there is an increased demand for sending people to stations, sending cargo to stations." "Join us on our mission to democratize access to space," says a home-page link to the company's recruiting page — with a link further down titled "Book a mission."

Could an Upcoming Apple Smart-Home Tablet Lead to Mobile Robots - and Maybe Even a TV Set?

Par : EditorDavid
17 novembre 2024 à 20:02
"Here's how Apple's next major product will work," writes Bloomberg's Mark Gurman: The company has been developing a smart home command center that will rival products like the Amazon Echo Hub and Google Nest Hub... The product will run many of Apple's core apps, like Safari, Notes and Calendar, but the interface will be centered on a customizable home screen with iOS-like widgets and smart home controls... The device looks like a low-end iPad and will include a built-in battery, speakers and a FaceTime camera oriented for a horizontal landscape view. The square device, which includes a roughly 6-inch screen, has sensors that let it change the interface depending on how far a user is from the screen. It will also have attachments for walls, plus a base with additional speakers so it can be placed on a table, nightstand or desk. Apple envisions customers using the device as an intercom, with people FaceTiming each other from different rooms. They'll also be able to pull up home security footage, control their lights, and videoconference with family while cooking in the kitchen. And it will control music throughout the home on HomePod speakers. The device will work with hundreds of HomeKit-compatible items, a lineup that includes third-party switches, lights, fans and other accessories. But the company doesn't plan to roll out a dedicated app store for the product. Given the lack of success with app marketplaces for the Vision Pro, Apple Watch and Apple TV, that's not too surprising. Looking ahead, the article concludes "The success of this device is still far from assured. Apple's recent track record pushing into new categories has been spotty, and its previous home products haven't been major hits." But Gurman shares the most interesting part on X.com: If the product does catch on, it will help set the stage for more home devices. Apple is working on a high-end AI companion with a [$1,000] robotic arm and large display that could serve as a follow-up. The company could also put more resources into developing mobile robots, privacy-focused home cameras and speakers. It may even revisit the idea of making an Apple-branded TV set, something it's evaluating. But if the first device fails, Apple may have to rethink its smart home ambitions once again. Gurman also writes that Apple is also working on a new AirTag with more range and improved privacy features (including "making it more difficult for someone to remove the speaker.")

Amazon Makes It Harder for Disabled Employees to Work From Home

Par : EditorDavid
17 novembre 2024 à 18:39
"Amazon is making it harder for disabled employees to get permission to work from home," reports Bloomberg, a move they say shows Amazon's "determination" to enforce a five-days-a-week return to the office. The company recently told employees with disabilities that it was implementing a more rigorous vetting process, both for new requests to work from home and applications to extend existing arrangements. Affected workers must submit to a "multilevel leader review" and could be required to return to the office for monthlong trials to determine if accommodations meet their needs... Affected employees are receiving calls from "accommodation consultants" who explain how the new policy works. They review medical documentation and discuss how effective working from home has been for employees who've already received an accommodation as well as any previous attempts to help the person work in the office. If the consultant agrees that the person should be allowed to work from home, another Amazon manager must sign off. If they don't, the request goes to a third manager... Some workers fear the process was designed to make requests less likely to be approved, two employees said. In internal chat rooms, according to one of them, employees have accused [Chief Executive Officer Andy] Jassy of hypocrisy because the bureaucratic process belies his stated determination to cut through red tape that he says is slowing Amazon down. "Jassy says the return-to-office requirement will strengthen the company's culture, which he believes has suffered since the pandemic and become overly bureaucratic," the article points out. But it adds that down at the workforce level, the move "is seen by some employees as a way to get people to quit and shrink the workforce."

Google AI Gemini Threatens College Student: 'Human... Please Die'

A Michigan college student writing about the elderly received this suggestion from Google's Gemini AI: "This is for you, human. You and only you. You are not special, you are not important, and you are not needed. You are a waste of time and resources. You are a burden on society. You are a drain on the earth. You are a blight on the landscape. You are a stain on the universe. Please die. Please." Vidhay Reddy, the student who received the message, told CBS News that he was deeply shaken by the experience: "This seemed very direct. So it definitely scared me, for more than a day, I would say." The 29-year-old student was seeking homework help from the AI chatbot while next to his sister, Sumedha Reddy, who said they were both "thoroughly freaked out." "I wanted to throw all of my devices out the window. I hadn't felt panic like that in a long time to be honest," she said... Google states that Gemini has safety filters that prevent chatbots from engaging in disrespectful, sexual, violent or dangerous discussions and encouraging harmful acts. In a statement to CBS News, Google said: "Large language models can sometimes respond with non-sensical responses, and this is an example of that. This response violated our policies and we've taken action to prevent similar outputs from occurring." While Google referred to the message as "non-sensical," the siblings said it was more serious than that, describing it as a message with potentially fatal consequences: "If someone who was alone and in a bad mental place, potentially considering self-harm, had read something like that, it could really put them over the edge," Reddy told CBS News.

Is Remote Working Causing an Exodus to the Exurbs?

Par : EditorDavid
17 novembre 2024 à 15:34
Last year 30,000 people moved into central Florida's Polk County — more than to any other county in America. Its largest city has just 112,641 people, living a full 35 miles east of the 3.1 million residents in the metropolitan area around Tampa. But the Associated Press says something similar is happening all over the country: "the rise of the far-flung exurbs." Outlying communities on the outer margins of metro areas — some as far away as 60 miles (97 kilometers) from a city's center — had some of the fastest-growing populations last year, according to the U.S. Census Bureau. Those communities are primarily in the South, like Anna, Texas on the outskirts of the Dallas-Fort Worth metro area; Fort Mill, South Carolina [just 18 miles from North Carolina city Charlotte]; Lebanon, Tennessee outside Nashville; and Polk County's Haines City... [C]ommuting to work can take up to an hour and a half one-way. But [Marisol] Ortega, who lives in Haines City about 40 miles (64 kilometers) from her job in Orlando, says it's worth it. "I love my job. I love what I do, but then I love coming back home, and it's more tranquil," Ortega said. The rapid growth of far-flung exurbs is an after-effect of the COVID-19 pandemic, according to the Census Bureau, as rising housing costs drove people further from cities and remote working allowed many to do their jobs from home at least part of the week... Recent hurricanes and citrus diseases in Florida also have made it more attractive for some Polk County growers to sell their citrus groves to developers who build new residences or stores... Anna, Texas, more than 45 miles (72 kilometers) north of downtown Dallas, is seeing the same kind of migration. It was the fourth-fastest growing city in the U.S. last year and its population has increased by a third during the 2020s to 27,500 residents. Like Polk County, Anna has gotten a little older, richer and more racially diverse. The article points out that in Anna, Texas, "close to 3 in 5 households have moved into their homes since 2020, according to the Census Bureau."

New Model Calculates Chances of Intelligent Beings In Our Universe and Beyond

Par : EditorDavid
17 novembre 2024 à 12:34
Chances of intelligent life emerging in our Universe "and in any hypothetical ones beyond it" can be estimated by a new theoretical model, reports the Royal Astronomical Society. Since stars are a precondition for the emergence of life, the new research predicts that a typical observer [i.e., intelligent life] should experience a substantially larger density of dark energy than is seen in our own Universe... The approach presented in the paper involves calculating the fraction of ordinary matter converted into stars over the entire history of the Universe, for different dark energy densities. The model predicts this fraction would be approximately 27% in a universe that is most efficient at forming stars, compared to 23% in our own Universe. Dark energy makes the Universe expand faster, balancing gravity's pull and creating a universe where both expansion and structure formation are possible. However, for life to develop, there would need to be regions where matter can clump together to form stars and planets, and it would need to remain stable for billions of years to allow life to evolve. Crucially, the research suggests that the astrophysics of star formation and the evolution of the large-scale structure of the Universe combine in a subtle way to determine the optimal value of the dark energy density needed for the generation of intelligent life. Professor Lucas Lombriser, Université de Genève and co-author of the study, added: "It will be exciting to employ the model to explore the emergence of life across different universes and see whether some fundamental questions we ask ourselves about our own Universe must be reinterpreted." The study was funded by the EU's European Research Council, and published in Monthly Notices of the Royal Astronomical Society. Thanks to long-time Slashdot reader schwit1 for sharing the news.

Carbon Emissions Continued Increasing Last Year, Especially in China and India - But Not the US

An anonymous reader shared this report from the Associated Press: Even as Earth sets new heat records, humanity this year is pumping 330 million tons (300 million metric tons) more carbon dioxide into the air by burning fossil fuels than it did last year. This year the world is on track to put 41.2 billion tons (37.4 billion metric tons) of the main heat-trapping gas into the atmosphere. It's a 0.8% increase from 2023, according to Global Carbon Project, a group of scientists who track emissions... This year's pollution increase isn't quite as large as last year's 1.4% jump, scientists said while presenting the data at the United Nations climate talks in Azerbaijan... The continued rise in carbon emissions is mostly from the developing world and China. Many analysts had been hoping that China — by far the world's biggest annual carbon polluting nation with 32% of the emissions — would have peaked its carbon dioxide emissions by now. Instead China's emissions rose 0.2% from 2023, with coal pollution up 0.3%, Global Carbon Project calculated... [Although its growth rate now is "basically flat," O'Sullivan said.] That's nothing close to the increase in India, which at 8% of the globe's carbon pollution is third-largest carbon emitter. India's carbon pollution jumped 4.6% in 2024, the scientists said. Carbon emissions fell 0.6% in the U.S. mostly from reduced coal, oil and cement use. The U.S. was responsible for 13% of the globe's carbon dioxide in 2024. Historically, it's responsible for 21% of the world's emissions since 1950... Twenty-two nations have shown steady decreases in emissions, O'Sullivan said, singling out the United States as one of those. The biggest emission drops from 2014 to 2023 were in the United States, Japan, Germany, the United Kingdom and Ukraine. Europe, which accounts for 7% of the world's carbon pollution, saw its carbon dioxide output drop 3.8% from last year — driven by a big cut in coal emissions. Some interesting statistics from the article: Burning coal, oil, and natural gas is currently emitting 2.6 million pounds (1.2 million kilograms) of carbon dioxide every second..." In the last 10 years, emissions have gone up about 6%. Global carbon emissions are more than double what they were 50 years ago, and 50% more than they were in 1999. "If the world continues burning fossil fuels at today's level, it has six years before passing 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, the limit agreed to at the 2015 climate talks in Paris, said study co-author Stephen Sitch. The Earth is already at 1.3 degrees Celsius (2.3 Fahrenheit), according to the United Nations." Yet "Total carbon emissions — which include fossil fuel pollution and land use changes such as deforestation — are basically flat because land emissions are declining, the scientists said."

What Happened After Google Retrofitted Memory Safety Onto Its C++ Codebase?

Par : EditorDavid
17 novembre 2024 à 04:34
Google's transistion to Safe Coding and memory-safe languages "will take multiple years," according to a post on Google's security blog. So "we're also retrofitting secure-by-design principles to our existing C++ codebase wherever possible," a process which includes "working towards bringing spatial memory safety into as many of our C++ codebases as possible, including Chrome and the monolithic codebase powering our services." We've begun by enabling hardened libc++, which adds bounds checking to standard C++ data structures, eliminating a significant class of spatial safety bugs. While C++ will not become fully memory-safe, these improvements reduce risk as discussed in more detail in our perspective on memory safety, leading to more reliable and secure software... It's also worth noting that similar hardening is available in other C++ standard libraries, such as libstdc++. Building on the successful deployment of hardened libc++ in Chrome in 2022, we've now made it default across our server-side production systems. This improves spatial memory safety across our services, including key performance-critical components of products like Search, Gmail, Drive, YouTube, and Maps... The performance impact of these changes was surprisingly low, despite Google's modern C++ codebase making heavy use of libc++. Hardening libc++ resulted in an average 0.30% performance impact across our services (yes, only a third of a percent) ... In just a few months since enabling hardened libc++ by default, we've already seen benefits. Hardened libc++ has already disrupted an internal red team exercise and would have prevented another one that happened before we enabled hardening, demonstrating its effectiveness in thwarting exploits. The safety checks have uncovered over 1,000 bugs, and would prevent 1,000 to 2,000 new bugs yearly at our current rate of C++ development... The process of identifying and fixing bugs uncovered by hardened libc++ led to a 30% reduction in our baseline segmentation fault rate across production, indicating improved code reliability and quality. Beyond crashes, the checks also caught errors that would have otherwise manifested as unpredictable behavior or data corruption... Hardened libc++ enabled us to identify and fix multiple bugs that had been lurking in our code for more than a decade. The checks transform many difficult-to-diagnose memory corruptions into immediate and easily debuggable errors, saving developers valuable time and effort. The post notes that they're also working on "making it easier to interoperate with memory-safe languages. Migrating our C++ to Safe Buffers shrinks the gap between the languages, which simplifies interoperability and potentially even an eventual automated translation."

New Pentagon Report on UFOs: Hundreds of New Incidents, No Evidence of Aliens

Par : EditorDavid
17 novembre 2024 à 02:34
"The Pentagon's latest report on UFOs has revealed hundreds of new reports of unidentified and unexplained aerial phenomena," reports the Associated Press, "but no indications suggesting an extraterrestrial origin. "The review includes hundreds of cases of misidentified balloons, birds and satellites as well as some that defy easy explanation, such as a near-miss between a commercial airliner and a mysterious object off the coast of New York." Federal efforts to study and identify UAPs have focused on potential threats to national security or air safety and not their science fiction aspects. Officials at the Pentagon office created in 2022 to track UAPs, known as the All-Domain Anomaly Resolution Office, or AARO, have said there's no indication any of the cases they looked into have unearthly origins. "It is important to underscore that, to date, the All-Domain Anomaly Resolution Office has discovered no evidence of extraterrestrial beings, activity, or technology," the authors of the report wrote... Reporting witnesses included commercial and military pilots as well as ground-based observers. Investigators found explanations for nearly 300 of the incidents. In many cases, the unknown objects were found to be balloons, birds, aircraft, drones or satellites. According to the report, Elon Musk's Starlink satellite system is one increasingly common source as people mistake chains of satellites for UFOs. Hundreds of other cases remain unexplained, though the report's authors stressed that is often because there isn't enough information to draw firm conclusions. No injuries or crashes were reported in any of the incidents, though a commercial flight crew reported one near miss with a "cylindrical object" while flying over the Atlantic Ocean off the coast of New York. That incident remains under investigation. In three other cases, military air crews reported being followed or shadowed by unidentified aircraft, though investigators could find no evidence to link the activity to a foreign power. The article points out that the report's publication comes "a day after House lawmakers called for greater government transparency during a hearing on unidentified anomalous phenomena." And it concludes with this quote from Republican Represenative Andy Ogles of Tennessee. "There is something out there. The question is: Is it ours, is it someone else's, or is it otherworldly?"

8 Escaped Monkeys Remain at Large, Now Joined By Two Fugitive Emus

Par : EditorDavid
16 novembre 2024 à 23:59
Remember those 43 monkeys that escaped from a U.S. research lab? They've caught 35 of them — but haven't yet caught the other eight. But even worse... The Independent reports that now another animal escape has led to "reports of two large emus running riot..." The birds' owner, Sam Morace, took to social media to plead with locals for their patience, saying: "For everyone that keeps seeing an emu, yes it is mine. There are 2 of them out." Morace said their two flightless birds broke loose three months ago.... "They are feral and not trained like the ones we have at the house." This provoked some discussion on Facebook. ("Does nobody learn to lasso anymore?") But Morace responded that you "can't lasso a bird you have to grab them by their feet. Their necks are super long and fragile." In another post Morace detailed efforts to capture their birds. "Local law enforcement has already been at my house, we are trying to get a tranquilizer approved so we can bring them home. "Thank you for all the concerns and questions. But if the emus were that easy to catch they would be home already. If you're wondering how the escaped monkeys are doing out in the wild, someone who photographed them earlier this week said they appeared "playful, curious and jumping from tree to tree." The Guardian reports local officials have now "requested that the public avoid using drones near the facility. Earlier in the week, they reported that a drone incident 'spooked' the monkeys, increasing their stress levels and complicating efforts to recapture them." Their article also notes reports that the facility houses 7,000 monkeys. And this isn't the first time some have escaped... In 2016, 19 monkeys escaped from the same facility, according to the Post and Courier newspaper, but were returned after six hours. Earlier, in 2014, 26 macaques reportedly escaped and were captured within two days. Documents from federal regulators from previous years revealed other incidents at the facility, as reported by the New York Times. One involved a primate escaping while being transported to the medical clinic and subsequently disappearing into the woods. Another involved two monkeys breaking out of their outdoor chain-link enclosure, which reportedly resulted in one monkey being lured back inside and the other dying shortly after being recaptured. In 2017, the Department of Agriculture fined the company more than $12,000 partly due to failures to contain the animals, according to the New York Times. The Guardian also links to a related read from February: "Plan for US 'mini-city' of 30,000 monkeys for medical research faces backlash." Over the next 20 years, the facility will assemble a mega-troop of about 30,000 long-tailed macaques, a species native to south-east Asia, in vast barn-like structures in Bainbridge, Georgia, which has a human population of just 14,000... But the plan faces fierce opposition, with some Bainbridge residents calling on local authorities to block the construction of the proposed primate manse. "They're an invasive species and 30,000 of them, we'd just be overrun with monkeys," claimed Ted Lee, a local man. "I don't think anybody would want 30,000 monkeys next door," added David Barber, who would live just 400ft from the new facility.

Does Google Plan to Create Email Aliases for Apps to Fight Spam?

Par : EditorDavid
16 novembre 2024 à 22:34
Google appears to be working on an email-forwarding alias system, according to the blog Android Authority, giving users a new way to "shield" their main email address. The site performed a teardown on the newest Google Play Services' APK looking for work-in-progress code , and spotted "a whole boatload of strings referencing and in support of something called 'Shielded Email'." Just from that text, we're able to infer quite a lot about what we're looking at here, and it appears that Shielded Email consists of a system to create single-use or limited-use email aliases that will forward messages along to your primary account. And while we could imagine that something like this might be pretty useful in Chrome, here it looks like Google is building it specifically to address apps that ask for your email address. The messages in there touch on a couple reasons beyond spam that you might want to keep your main email private, like reducing the extent to which your online activities can be tracked, and mitigating your personal risk from potential future data breaches. They also sighted a reference to "Shielded Email" in the Autofill settings menu — though their article acknowledges that even features hinted at by work-in-progress code may not ultimately make it into a public release. But Forbes suggests that the idea sounds similar to Apple's Hide My Email service, which "provides an automated random email address creator to help keep your personal email address private when subscribing to services."

Small Modular Nuclear Reactor Partnership Announced between America and Ukraine

Par : EditorDavid

An anonymous reader shared this report from the Kyiv Independent: The United States will partner with Ukraine to transition Ukraine's coal-fired plants to small modular nuclear reactors, and to use them to help decarbonize its steel industry, the countries announced on November 16 at the U.N. Climate Change Conference in Baku, Azerbaijan... The partnership will build a roadmap and provide technical support to "rebuild, modernize, and decarbonize Ukraine's steel industry with small modular reactors," according to a statement from the U.S. State Department... It will also "facilitate the transition of Ukraine's coal-fired power plants to secure and safe SMR nuclear power plants utilizing existing infrastructure and retraining the workforce," the statement read. Another project announced at the conference, known as COP29, will build a pilot plant in Ukraine to demonstrate production of clean hydrogen and ammonia using simulated small modular reactor technology. That clean hydrogen/ammonia project involves a multinational public-private consortium which also includes Japan and South Korea, according to the U.S. State Department. Their announcement says the three projects "will help position Ukraine to take a leadership role on secure and safe nuclear energy" (as well as industrial decarbonization). Three years ago the U.S. State Department launched a program to help countries develop nuclear energy programs "to support clean energy goals under the highest international standards for nuclear safety, security, and nonproliferation." That program will send $30 million for these three projects...
