India's Plan To Let 1998 Digital Trade Deal Expire May Worsen Chip Shortage

Slashdot - 24 February, 2024 - 11:02
An anonymous reader quotes a report from Ars Technica: India's plan to let a moratorium on imposing customs duties on cross-border digital e-commerce transactions expire may end up hurting India's more ambitious plans to become a global chip leader in the next five years, Reuters reported. It could also worsen the global chip shortage by spiking semiconductor industry costs at a time when many governments worldwide are investing heavily in expanding domestic chip supplies in efforts to keep up with rapidly advancing technologies. Early next week, world leaders will convene at a World Trade Organization (WTO) meeting, just before the deadline to extend the moratorium hits in March. In place since 1998, the moratorium has been renewed every two years since -- but India has grown concerned that it's losing significant revenues from not imposing taxes as demand rises for its digital goods, like movies, e-books, or games. Hoping to change India's mind, a global consortium of semiconductor industry associations known as the World Semiconductor Council (WSC) sent a letter to Indian Prime Minister Narendra Modi on Thursday. Reuters reviewed the letter, reporting that the WSC warned Modi that ending the moratorium "would mean tariffs on digital e-commerce and an innumerable number of transfers of chip design data across countries, raising costs and worsening chip shortages." Pointing to Modi's $10 billion semiconductor incentive package -- which Modi has said is designed to advance India's industry through "giant leaps" in its mission to become a technology superpower -- the WSC cautioned Modi that pushing for customs duties may dash those global chip leader dreams. Studies suggest that India should be offering tax incentives, not potentially threatening to impose duties on chip design data. That includes a study from earlier this year, released after the Semiconductor Industry Association and the India Electronics and Semiconductor Association commissioned a report from the Information Technology and Innovation Foundation (ITIF). [...] It's possible that India and other developing nations may seek to narrow the moratorium rather than end it. An Indian government official told Reuters that "these issues need to be discussed and settled" before India can make a decision on whether to extend the moratorium.

US Man Accused of Making $1.8 Million From Listening In On Wife's Remote Work Calls

Slashdot - 24 February, 2024 - 10:20
Kalyeena Makortoff reports via The Guardian: US regulators have accused a man of making $1.8 million by trading on confidential information he overheard while his wife was on a remote call, in a case that could fuel arguments against working from home. The Securities and Exchange Commission (SEC) said it charged Tyler Loudon with insider trading after he "took advantage of his remote working conditions" and profited from private information related to the oil firm BP's plans to buy an Ohio-based travel centre and truck-stop business last year. The SEC claims that Loudon, who is based in Houston, Texas, listened in on several remote calls held by his wife, a BP merger and acquisitions manager who had been working on the planned deal in a home office 20ft (6 meters) away. The regulator said Loudon went on a buying spree, purchasing more than 46,000 shares in the takeover target, TravelCenters of America, without his wife's knowledge, weeks before the deal was announced on 16 February 2023. TravelCenters's stock soared by nearly 71% after the deal was announced. Loudon then sold off all of his shares, making a $1.8m profit. Loudon eventually confessed to his wife, and claimed that he had bought the shares because he wanted to make enough money so that she did not have to work long hours anymore. She reported his dealings to her bosses at BP, which later fired her despite having no evidence that she knowingly leaked information to her husband. She eventually moved out of the couple's home and filed for divorce.

Google Is Sunsetting the Google Pay App

Slashdot - 24 February, 2024 - 09:40
Google is shutting down the Google Pay app, as the standalone app has largely been replaced by Google Wallet. According to TechCrunch, Google Pay "will only be available in Singapore and India" after its shuts down in the United States. From the report: Users can continue to access the app's most popular features right from Google Wallet, which Google says is used five times more than the Google Pay app in the United States. After June 4, users will no longer be able to send, request or receive money through the U.S. version of the Google Pay app. Users have until that date to view and transfer their Google Pay balance to their bank account via the app. If you still have funds in your account after that date, you can view and transfer your funds to your bank from the Google Pay website. Users who used the Google Pay app to find offers and deals can still so do using the new deals destination on Google Search, the company says. Google Wallet is the company's primary place for mobile payments in the United States, and will likely remain so. The app lets you use your phone to pay in stores, board a plane, ride transit, store loyalty cards, save driver's licenses and start your car via a digital key.

Tyler Perry Puts $800M Studio Expansion On Hold After Seeing OpenAI's Sora

Slashdot - 24 February, 2024 - 09:00
An anonymous reader quotes a report from the Hollywood Reporter: Over the past four years, Tyler Perry had been planning an $800 million expansion of his studio in Atlanta, which would have added 12 soundstages to the 330-acre property. Now, however, those ambitions are on hold -- thanks to the rapid developments he's seeing in the realm of artificial intelligence, including OpenAI's text-to-video model Sora, which debuted Feb. 15 and stunned observers with its cinematic video outputs. "Being told that it can do all of these things is one thing, but actually seeing the capabilities, it was mind-blowing," he said in an interview with The Hollywood Reporter on Thursday, noting that his productions might not have to travel to locations or build sets with the assistance of the technology. As a business owner, Perry sees the opportunity in these developments, but as an employer, fellow actor and filmmaker, he also wants to raise the alarm. In an interview between shoots Thursday, Perry explained his concerns about the technology's impact on labor and why he wants the industry to come together to tackle AI: "There's got to be some sort of regulations in order to protect us. If not, I just don't see how we survive." What in particular was shocking to you about its capabilities? Perry: I no longer would have to travel to locations. If I wanted to be in the snow in Colorado, it's text. If I wanted to write a scene on the moon, it's text, and this AI can generate it like nothing. If I wanted to have two people in the living room in the mountains, I don't have to build a set in the mountains, I don't have to put a set on my lot. I can sit in an office and do this with a computer, which is shocking to me. It makes me worry so much about all of the people in the business. Because as I was looking at it, I immediately started thinking of everyone in the industry who would be affected by this, including actors and grip and electric and transportation and sound and editors, and looking at this, I'm thinking this will touch every corner of our industry. How are you thinking about approaching the threat that AI poses to certain job categories at your studio and on your productions? Perry: Everything right now is so up in the air. It's so malleable. The technology's moving so quickly. I feel like everybody in the industry is running a hundred miles an hour to try and catch up, to try and put in guardrails and to try and put in safety belts to keep livelihoods afloat. But me, just like every other studio in town, we're all trying to figure it all out. I think we're all trying to find the answers as we go, and it's changing every day -- and it's not just our industry, but it's every industry that AI will be affecting, from accountants to architects. If you look at it across the world, how it's changing so quickly, I'm hoping that there's a whole government approach to help everyone be able to sustain. You can read the full interview here.

Reddit Warns That r/WallStreetBets Could Wreak Havoc on Its Stock Price

Slashdot - 24 February, 2024 - 08:20
An anonymous reader shares a report: Beware the apes, Reddit told the world in its IPO documents, though not in such explicit terms. Put simply, the company warned potential investors that one of its subreddits, the infamous r/WallStreetBets, could make its stock price and volume extremely volatile -- and there's little Reddit can do about it. Reddit listed r/WallStreetBets as one of the possible risks to investing in the company in its S-1 form on Thursday, referencing the subreddit's role in the meme stock craze of 2021, where retail investors banded together to raise the price of struggling companies like GameStop and AMC. The goal of r/WallStreetBets back then was to screw over professional investors on Wall Street and make them lose money for betting against certain companies. It's entirely possible that the everyday people on r/WallStreetBets, a subreddit of 15 million retail investors who refer to themselves as "apes" and "degenerates," and other online forums could do the same thing with Reddit's stock, the company stated. Reddit writes: "Given the broad awareness and brand recognition of Reddit, including as a result of the popularity of r/ wallstreetbets among retail investors, and the direct access by retail investors to broadly available trading platforms, the market price and trading volume of our Class A common stock could experience extreme volatility for reasons unrelated to our underlying business or macroeconomic or industry fundamentals." The volatility could cause people to lose all or part of their investment, the company explained, if they are unable to sell their shares at or above the IPO price. The long-term effect of movements like those propelled by r/WallStreetBets is already documented, with the takeaway being that surges of interest and heavy investment don't necessarily bring success to companies over time.

Vision Pro Owners Are Reporting a Mysterious Crack in the Front Glass

Slashdot - 24 February, 2024 - 07:42
An anonymous reader shares a report: Vision Pro owners are posting near-identical reports of a crack appearing on the front glass of their headsets. None of them seem to know how it happened, either. The issue was first spotted by MacRumors, and so far, there have been five separate Redditors who have posted about it in the r/VisionPro subreddit. Engadget also reported that the same happened with its review unit. What makes it curious is that all of the uploaded pictures appear to show vertical hairline cracks in the same exact area above the nose bridge. All the affected Redditors say they didn't do anything obvious to cause the cracks, like dropping the device or storing it improperly. Reddit user @dornbirn claims that they polished the front glass, placed the soft cover on, packed it away in the case, and woke up to see the crack the next morning. Most of the other affected Redditors also noted they either stored their Vision Pros in cases or placed the soft cover on.

Staff Say Dell's Return To Office Mandate is a Stealth Layoff

Slashdot - 24 February, 2024 - 07:01
Dell's "return to office" mandate has left employees confused about which offices they can use and the future of their jobs -- and concerned the initiative is a stealth layoff program that will disproportionately harm women at the IT giant. From a report: As El Reg broke this month, Dell told employees they each needed to choose between resuming a hybrid work schedule -- working from a corporate office part of the time -- or continue working remotely. Those who chose to remain as remote workers were effectively making a career-limiting decision. The implications of choosing to work remotely, we're told, are: "1) no funding for team onsite meetings, even if a large portion of the team is flying in for the meeting from other Dell locations; 2) no career advancement; 3) no career movements; and 4) remote status will be considered when planning or organization changes -- AKA workforce reductions." Another employee said: "Choosing to be remote does indeed put career advancement at a standstill. If you choose to accept a promotion after going remote, that comes with the requirement of being in office 39 days out of the quarter" and you have to reclassify yourself as hybrid. The employee continued: "Even if you choose to make a lateral career move, the same expectation applies. In-role promotions are possible, but rare enough to not be a realistic option."

Tech Job Interviews Are Out of Control

Slashdot - 24 February, 2024 - 06:20
Tech companies are famous for coddling their workers, but after mass layoffs the industry's culture has shifted. Engineers say that getting hired can require days of work on unpaid assignments. From a report: Nearly a dozen engineers, hiring managers, and entrepreneurs who spoke with WIRED describe an environment in which technical job applicants are being put through the wringer. Take-home coding tests used to be rare, deployed only if an employer needed to be further convinced. Now interviewees are regularly given projects described as requiring just two to three hours that instead take days of work. Live-coding exercises are also more intense, industry insiders say. One job seeker described an experience where an engineering manager said during an interview, "OK, we're going to build a To Do List app right now," a process that might normally take weeks. Emails reviewed by WIRED showed that in one interview for an engineering role at Netflix, a technical recruiter requested that a job candidate submit a three-page project evaluation within 48 hours -- all before the first round of interviews. A Netflix spokesperson said the process is different for each role and otherwise declined to comment. A similar email at Snap outlined a six-part interview process for a potential engineering candidate, with each part lasting an hour. A company spokesperson says its interview process hasn't changed as a result of labor market changes.

An anonymous reader shares a report: News publishers are worried -- with good reason -- about changes coming to Google Search. AI-generated content replacing links on some of the most valuable space on the internet, in particular, has left media types with a lot of questions, starting with "is this going to be a traffic-destroying nightmare?" The News filter disappearing from Google search results for some users this week won't help publishers sleep any easier. Google confirmed some users were not seeing the News filter as part of ongoing testing. "We're testing different ways to show filters on Search and as a result, a small subset of users were temporarily unable to access some of them," a Google spokesperson confirmed via email.

Ransomware Associated With LockBit Still Spreading 2 Days After Server Takedown

Slashdot - 24 February, 2024 - 05:00
Two days after an international team of authorities struck a major blow to LockBit, one of the Internet's most prolific ransomware syndicates, researchers have detected a new round of attacks that are installing malware associated with the group. From a report: The attacks, detected in the past 24 hours, are exploiting two critical vulnerabilities in ScreenConnect, a remote desktop application sold by Connectwise. According to researchers at two security firms -- SophosXOps and Huntress -- attackers who successfully exploit the vulnerabilities go on to install LockBit ransomware and other post-exploit malware. It wasn't immediately clear if the ransomware was the official LockBit version. "We can't publicly name the customers at this time but can confirm the malware being deployed is associated with LockBit, which is particularly interesting against the backdrop of the recent LockBit takedown," John Hammond, principal security researcher at Huntress, wrote in an email. "While we can't attribute this directly to the larger LockBit group, it is clear that LockBit has a large reach that spans tooling, various affiliate groups, and offshoots that have not been completely erased even with the major takedown by law enforcement." Hammond said the ransomware is being deployed to "vet offices, health clinics, and local governments (including attacks against systems related to 911 systems)."

The Sun Just Launched Three Huge Solar Flares in 24 Hours.

Slashdot - 24 February, 2024 - 03:40
Three top-tier X-class solar flares launched off the sun between Wednesday and Thursday. The first two occurred seven hours apart, coming in at X1.9 and X1.6 magnitude respectively. The third, the most powerful of the current 11-year "solar cycle," ranked an impressive X6.3. From a report: Solar flares, or bursts of radiation, are ranked on a scale that goes from A, B and C to M and X, in increasing order of intensity. They usually originate from sunspots, or bruiselike discolorations on the surface of the sun. Sunspots are most common near the height of the 11-year solar cycle. The current cycle, number 25, is expected to reach its peak this year. The more sunspots, the more opportunities for solar flares. Solar flares and accompanying coronal mass ejections, or CMEs, can influence "space weather" across the solar system, and even here on Earth. CMEs are slower shock waves of magnetic energy from the sun. Flares can reach Earth in minutes, but CMEs usually take at least a day. All three of the X-class solar flares disrupted shortwave radio communications on Earth. But the first two flares did not release a CME; the verdict is still out regarding whether the third flare did. High-frequency radio waves propagate by bouncing off electrons in Earth's ionosphere. That's a layer of Earth's atmosphere between 50 and 600 miles above the ground. When a solar flare occurs, that radiation travels toward Earth at the speed of light. It can ionize additional particles in the lower ionosphere. Radio waves sent from devices below it then impact that extra-ionized layer and lose energy, and aren't able to be bent by ions at the top of the ionosphere. That means signals can't travel very far, and radio blackouts are possible. Three back-to-back radio blackouts occurred in response to the trio of flares, but primarily over the Pacific and Indian oceans. They were rated "R3" or greater on a 1 through 5 scale. According to the National Oceanic and Atmospheric Administration's Space Weather Prediction Center, that results in a "wide area blackout of [high frequency] radio communication, [and] loss of radio contact for about an hour on sunlit side of Earth." Low-frequency navigation signals, like those used on aircraft traveling overseas, can be degraded too.

Leisure Firm in UK Told Scanning Staff Faces is Illegal

Slashdot - 24 February, 2024 - 02:24
Bruce66423 writes: The data watchdog has ordered a leisure centre group to stop using facial recognition tech to monitor its staff. The Information Commissioner's Office (ICO) says Serco Leisure has been unlawfully processing the biometric data of more than 2,000 employees at 38 UK leisure facilities. It did so to check staff attendance - a practice the ICO said was "neither fair nor proportionate." Serco Leisure says it will comply with the enforcement notice. But it added it had taken legal advice prior to installing the cameras, and said staff had not complained about them during the five years they had been in place. The firm said it was to "make clocking-in and out easier and simpler" for workers. "We engaged with our team members in advance of its roll-out and its introduction was well-received by colleagues," the company said in a statement.

UnitedHealth Says Change Healthcare Hacked by Nation State, as US Pharmacy Outages Drag On

Slashdot - 24 February, 2024 - 01:48
U.S. health insurance giant UnitedHealth Group said Thursday in a filing with government regulators that its subsidiary Change Healthcare was compromised likely by government-backed hackers. From a report: In a filing Thursday, UHG blamed the ongoing cybersecurity incident affecting Change Healthcare on suspected nation state hackers but said it had no timeframe for when its systems would be back online. UHG did not attribute the cyberattack to a specific nation or government, or cite what evidence it had to support its claim. Change Healthcare provides patient billing across the U.S. healthcare system. The company processes billions of healthcare transactions annually and claims it handles around one-in-three U.S. patient records, amounting to around a hundred million Americans. The cyberattack began early Wednesday, according to the company's incident tracker.

JSTOR is Now Available in 1,000 Prisons

Slashdot - 24 February, 2024 - 01:08
JSTOR: At the end of 2023, JSTOR -- a vast digital library of secondary and primary sources to support teaching and learning -- reached a once unimaginable goal: providing JSTOR access in 1,000 prisons. Spread across four continents, the JSTOR Access in Prison initiative now supports the education and growth of more than 550,000 incarcerated people. Incarcerated learners have been left behind for decades. Limited access to the internet and scarce funding and support for higher education in prisons made access to digital libraries like JSTOR all but impossible. In October 2021, with funding from the Mellon Foundation, JSTOR set an ambitious goal to change that. The aspiration? For every incarcerated college student in the United States to have access to JSTOR, along with the research skills to use it and other digital resources. Prior to 2021, JSTOR developed an offline index of its digital library. At the time, less than twenty prisons had access to it. Since then, developers have created an online version that meets the unique needs of carceral settings, most recently delivering online access on tablets. These changes -- and the leadership of Stacy Burnett, a graduate of the Bard Prison Initiative who was hired to lead the JSTOR Access in Prison initiative -- have enabled 1,000 prisons and more than 500,000 people to gain access to the digital equivalent of a college library.

Stable Diffusion 3.0 Debuts New Architecture To Reinvent Text-To-Image Gen AI

Slashdot - 24 February, 2024 - 00:00
An anonymous reader quotes a report from VentureBeat: Stability AI is out today with an early preview of its Stable Diffusion 3.0 next-generation flagship text-to-image generative AI model. The new Stable Diffusion 3.0 model aims to provide improved image quality and better performance in generating images from multi-subject prompts. It will also provide significantly better typography than prior Stable Diffusion models enabling more accurate and consistent spelling inside of generated images. Typography has been an area of weakness for Stable Diffusion in the past and one that rivals including DALL-E 3, Ideogram and Midjourney have also been working on with recent releases. Stability AI is building out Stable Diffusion 3.0 in multiple model sizes ranging from 800M to 8B parameters. Stable Diffusion 3.0 isn't just a new version of a model that Stability AI has already released, it's actually based on a new architecture. "Stable Diffusion 3 is a diffusion transformer, a new type of architecture similar to the one used in the recent OpenAI Sora model," Emad Mostaque, CEO of Stability AI told VentureBeat. "It is the real successor to the original Stable Diffusion." [...] Stable Diffusion 3.0 is taking a different approach by using diffusion transformers. "Stable Diffusion did not have a transformer before," Mostaque said. Transformers are at the foundation of much of the gen AI revolution and are widely used as the basis of text generation models. Image generation has largely been in the realm of diffusion models. The research paper that details Diffusion Transformers (DiTs), explains that it is a new architecture for diffusion models that replaces the commonly used U-Net backbone with a transformer operating on latent image patches. The DiTs approach can use compute more efficiently and can outperform other forms of diffusion image generation. The other big innovation that Stable Diffusion benefits from is flow matching. The research paper on flow matching explains that it is a new method for training Continuous Normalizing Flows (CNFs) to model complex data distributions. According to the researchers, using Conditional Flow Matching (CFM) with optimal transport paths leads to faster training, more efficient sampling, and better performance compared to diffusion paths.

Mercedes-Benz Backs Off Plan To Only Sell EVs By 2030

Slashdot - 23 February, 2024 - 21:00
In its fourth quarter earnings statement on Thursday, Mercedes-Benz said it is backing off its plan to only sell electric vehicles after 2030. Instead, the company said it "only expects 50 percent of its sales to be all-electric -- a significant drop from the once rosier outlook," reports The Verge. "Gas and hybrid vehicles will remain a part of the company's future for years to come." From the report: "Customers and market conditions will set the pace of the transformation," Mercedes said in its report. "The company plans to be in a position to cater to different customer needs, whether it's an all-electric drivetrain or an electrified combustion engine, until well into the 2030s." Not even in Europe, where EV sales growth outpaces North America's, does Mercedes expect to transition to EV-only sales anytime soon, the company's CEO Ola Kallenius told Reuters. "It's not going to be 100% in 2030, obviously... from the whole European market, but probably from the Mercedes side as well," he said. In 2021, Mercedes was a lot more bullish about plug-in powertrains, saying that by 2030 it would only sell EVs and completely phase out gas-powered vehicles.

Switzerland Calls On UN To Explore Possibility of Solar Geoengineering

Slashdot - 23 February, 2024 - 18:00
Switzerland is advocating for a United Nations expert group to explore the merits of solar geoengineering. The proposal seeks to ensure multilateral oversight of solar radiation modification (SRM) research, amidst concerns over its potential implications for food supply, biodiversity, and global inequalities. The Guardian reports: The Swiss proposal, submitted to the United Nations environment assembly that begins next week in Nairobi, focuses on solar radiation modification (SRM). This is a technique that aims to mimic the effect of a large volcanic eruption by filling the atmosphere with sulphur dioxide particles that reflect part of the sun's heat and light back into space. Supporters of the proposal, including the United Nations environment program (UNEP), argue that research is necessary to ensure multilateral oversight of emerging planet-altering technologies, which might otherwise be developed and tested in isolation by powerful governments or billionaire individuals. Critics, however, argue that such a discussion would threaten the current de-facto ban on geoengineering, and lead down a "slippery slope" towards legitimization, mainstreaming and eventual deployment. Felix Wertli, the Swiss ambassador for the environment, said his country's goal in submitting the proposal was to ensure all governments and relevant stakeholders "are informed about SRM technologies, in particular about possible risks and cross-border effects." He said the intention was not to promote or enable solar geoengineering but to inform governments, especially those in developing countries, about what is happening. The executive director of the UNEP, Inger Andersen, stressed the importance of "a global conversation on SRM" in her opening address to delegates at a preliminary gathering in Nairobi. She and her colleagues emphasized the move was a precautionary one rather than an endorsement of the technology.

Facial-Recognition System Passes Test On Michelangelo's David

Slashdot - 23 February, 2024 - 14:30
An anonymous reader quotes a report from Ars Technica: Facial recognition is a common feature for unlocking smartphones and gaming systems, among other uses. But the technology currently relies upon bulky projectors and lenses, hindering its broader application. Scientists have now developed a new facial recognition system that employs flatter, simpler optics that also require less energy, according to a recent paper published in the journal Nano Letters. The team tested their prototype system with a 3D replica of Michelangelo's famous David sculpture and found it recognized the face as well as existing smartphone facial recognition can. [...] Wen-Chen Hsu, of National Yang Ming Chiao Tung University and the Hon Hai Research Institute in Taiwan, and colleagues turned to ultrathin optical components known as metasurfaces for a potential solution. These metasurfaces can replace bulkier components for modulating light and have proven popular for depth sensors, endoscopes, tomography. and augmented reality systems, among other emerging applications. Hsu et al. built their own depth-sensing facial recognition system incorporating a metasurface hologram in place of the diffractive optical element. They replaced the standard vertical-cavity surface-emitting laser (VCSEL) with a photonic crystal surface-emitting laser (PCSEL). (The structure of photonic crystals is the mechanism behind the bright iridescent colors in butterfly wings or beetle shells.) The PCSEL can generate its own highly collimated light beam, so there was no need for the bulky light guide or collimation lenses used in VCSEL-based dot projector systems. The team tested their new system on a replica bust of David, and it worked as well as existing smartphone facial recognition, based on comparing the infrared dot patterns to online photos of the statue. They found that their system generated nearly one and a half times more infrared dots (some 45,700) than the standard commercial technology from a device that is 233 times smaller in terms of surface area than the standard dot projector. "It is a compact and cost-effective system, that can be integrated into a single chip using the flip-chip process of PCSEL," the authors wrote. Additionally, "The metasurface enables the generation of customizable and versatile light patterns, expanding the system's applicability." It's more energy-efficient to boot.
