Supernova Slowdowns Confirm Einstein's Predictions of Time Dilation

Par : BeauHD
22 juin 2024 à 10:00
Jonathan O'Callaghan reports via Scientific American: Despite more than a century of efforts to show otherwise, it seems Albert Einstein can still do no wrong. Or at least that's the case for his special theory of relativity, which predicts that time ticks slower for objects moving at extremely high speeds. Called time dilation, this effect grows in intensity the closer to the speed of light that something travels, but it is strangely subjective: a passenger on an accelerating starship would experience time passing normally, but external observers would see the starship moving ever slower as its speed approached that of light. As counterintuitive as this effect may be, it has been checked and confirmed in the motions of everything from Earth-orbiting satellites far-distant galaxies. Now a group of scientists have taken such tests one step further by observing more than 1,500 supernovae across the universe to reveal time dilation's effects on a staggering cosmic scale. The researchers' findings, once again, reach an all-too-familiar conclusion. "Einstein is right one more time," says Geraint Lewis of the University of Sydney, a co-author of the study. In the paper, posted earlier this month on the preprint server arXiv.org, Ryan White of the University of Queensland in Australia and his colleagues used data from the Dark Energy Survey (DES) to investigate time dilation. For the past decade, researchers involved with DES had used the Victor M. Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile to study particular exploding stars called Type 1a supernovae across billions of years of cosmic history. [...] Type 1a supernovae are keystone cosmic explosions caused when a white dwarf -- the slowly cooling corpse of a midsized star -- siphons so much material from a companion that it ignites a thermonuclear reaction and explodes. This explosion occurs once the growing white dwarf reaches about 1.44 times the mass of our sun, a threshold known as the Chandrasekhar limit. This physical baseline imbues all Type 1a supernovae with a fairly consistent brightness, making them useful cosmic beacons for gauging intergalactic distances. "They should all be essentially the same kind of event no matter where you look in the universe," White says. "They all come from exploding white dwarf stars, which happens at almost exactly the same mass no matter where they are." The steadfastness of these supernovae across the entire observable universe is what makes them potent probes of time dilation -- nothing else, in principle, should so radically and precisely slow their apparent progression in lockstep with ever-greater distances. Using the dataset of 1,504 supernovae from DES, White's paper shows with astonishing accuracy that this correlation holds true out to a redshift of 1.2, a time when the universe was about five billion years old. "This is the most precise measurement" of cosmological time dilation yet, White says, up to seven times more precise than previous measurements of cosmological time dilation that used fewer supernovae. [...] This particular supernova-focused facet of the Dark Energy Survey has concluded, so until a new dataset is taken, White's measurement of cosmological time dilation is unlikely to be beaten. "It's a pretty definitive measurement," says [Tamara Davis of the University of Queensland, a co-author of the paper]. "You don't really need to do any better."

Youth Plaintiffs In Hawaii Reach Historic Climate Deal

22 juin 2024 à 07:00
Justine Calma writes via The Verge: A group of young plaintiffs reached a historic climate settlement with the state of Hawaii and Hawaii Department of Transportation in a deal that will push the state to clean up tailpipe pollution. The 13 youth plaintiffs filed suit in 2022 when they were all between the ages of 9 and 18. In the suit, Navahine F. v. Hawaii Department of Transportation (HDOT), they alleged that the state and HDOT had violated their right to "a clean and healthful environment," which is enshrined in Hawaii's constitution. The settlement (PDF), reached on Thursday, affirms that right and commits the DOT to creating a plan to reach zero greenhouse gas emissions from transportation by 2045. To hit that goal, the state will have to dedicate at least $40 million to building out its EV charging network by the end of the decade and complete new pedestrian, bicycle, and transit networks over the next five years. The settlement also creates a new unit within HDOT tasked with coordinating CO2 emission reductions and a volunteer youth council to advise HDOT. This is the first settlement agreement in which "government defendants have decided to resolve a constitutional climate case in partnership with youth plaintiffs," according to nonprofit legal groups Our Children's Trust and Earthjustice, which represent the plaintiffs. Back in 2018, Hawaii committed to reaching net-zero carbon dioxide emissions by 2045 -- in line with what climate research determined was necessary to meet the Paris climate accord goal of stopping global warming. But the state wasn't doing enough to reach that goal, the plaintiffs alleged. Transportation makes up the biggest chunk of the state's greenhouse gas pollution.

Why Going Cashless Has Turned Sweden Into a High-Crime Nation

Par : BeauHD
22 juin 2024 à 03:30
An anonymous reader quotes a report from Fortune: Ellen Bagley was delighted when she made her first sale on a popular second-hand clothing app, but just a few minutes later, the thrill turned to shock as the 20-year-old from Linkoping in Sweden discovered she'd been robbed. Everything seemed normal when Bagley received a direct message on the platform, which asked her to verify personal details to complete the deal. She clicked the link, which fired up BankID -- the ubiquitous digital authorization system used by nearly all Swedish adults.After receiving a couple of error messages, she started thinking something was wrong, but it was already too late. Over 10,000 Swedish kronor ($1,000) had been siphoned from her account and the thieves disappeared into the digital shadows. "The fraudsters are so skilled at making things look legitimate," said Bagley, who was born after BankID was created. "It's not easy" to identify scams. Although financial crime has garnered fewer headlines than a surge in gang-related gun violence, it's become a growing risk for the country. Beyond its borders, Sweden is an important test case on fighting cashless crime because it's gone further on ditching paper money than almost any other country in Europe. Online fraud and digital crime in Sweden have surged, with criminals taking 1.2 billion kronor in 2023 through scams like the one Bagley fell for, doubling from 2021. Law-enforcement agencies estimate that the size of Sweden's criminal economy could amount to as high as 2.5% of the country's gross domestic product. To counter the digital crime spree, Swedish authorities have put pressure on banks to tighten security measures and make it harder on tech-savvy criminals, but it's a delicate balancing act. Going too far could slow down the economy, while doing too little erodes trust and damages legitimate businesses in the process.Using complex webs of fake companies and forging documents to gain access to Sweden's welfare system, sophisticated fraudsters have made Sweden a "Silicon Valley for criminal entrepreneurship," said Daniel Larson, a senior economic crime prosecutor. While the shock of armed violence has grabbed public attention -- the nation's gun-homicide rate tripled between 2012 and 2022 -- economic crime underlies gang activity and needs to be tackled as aggressively, he added. "That has been a strategic mistake," Larson said. "This profit-generating crime is what's fueling organized crime and, in some cases, leads to these conflicts." Sweden's switch to electronic cash started after a surge of armed robberies in the 1990s, and by 2022, only 8% of Swedes said they had used cash for their latest purchase, according to a central bank survey. Along with neighboring Norway, Sweden has Europe's lowest number of ATMs per capita, according to the IMF. The prevalence of BankID play a role in Sweden's vulnerability. The system works like an online signature. If used, it's considered a done deal and the transaction gets executed immediately. It was designed by Sweden's banks to make electronic payments even quicker and easier than handing over a stack of bills. Since it's original rollout in 2001, it's become part of the everyday Swedish life. On average, the service -- which requires a six-digit code, a fingerprint or a face scan for authentication -- is used more than twice a day by every adult Swede and is involved in everything from filing tax returns to paying for bus tickets.Originally intended as a product by banks for their customers, its use exploded in 2005 after Sweden's tax agency adopted the technology as an identification for tax returns, giving it the government's official seal of approval. The launch of BankID on mobile phones in 2010 increased usage even further, along with public perception that associated cash with criminality.The country's central bank has acknowledged that some of those connotations may have gone too far. "We have to be very clear that there are still honest people using cash," Riksbank Governor Erik Thedeen told Bloomberg.

iOS 18 Brings AirPods Setup Experience To Third-Party Accessories

Par : BeauHD
21 juin 2024 à 23:40
Filipe Esposito reports via 9to5Mac: When Apple introduced AirPods in 2016, the company also unveiled a new, easy and intuitive way to pair wireless accessories to iPhone and iPad. Rather than having to go to Bluetooth settings and press buttons, the system identifies the accessory nearby and prompts the user to pair it. With iOS 18, this quick pairing process will be available for the first time to accessory makers. Called AccessorySetupKit, the new API gives third-party accessories the same setup experience as Apple accessories such as AirPods and AirTag. As soon as the iPhone or iPad running iOS 18 with the right app detects a compatible accessory, it will show the user a popup to confirm pairing with that device. With just a tap, the system will automatically handle all the Bluetooth or Wi-Fi connectivity required by the accessory. This also means that users will no longer have to manually give Bluetooth and Wi-Fi permissions individually to that accessory's app. If the accessory requires a more complex pairing process, such as confirming a PIN code, the iOS 18 API can also ask the user for this information without the need to open an app. Once the accessory has been paired, more information about it can be found in a new Accessories menu within the Privacy settings.

OpenAI's First Acquisition Is Enterprise Data Startup 'Rockset'

Par : BeauHD
21 juin 2024 à 23:00
In a bog post on Friday, OpenAI announced it has acquired Rockset, an enterprise analytics startup, to "power our retrieval infrastructure across products." The Verge reports: This acquisition is OpenAI's first where the company will integrate both a company's technology and its team, a spokesperson tells Bloomberg. The two companies didn't share the terms of the acquisition. Rockset has raised $105 million in funding to date. "Rockset's infrastructure empowers companies to transform their data into actionable intelligence," OpenAI COO Brad Lightcap says in a statement. "We're excited to bring these benefits to our customers by integrating Rockset's foundation into OpenAI products." "Rockset will become part of OpenAI and power the retrieval infrastructure backing OpenAI's product suite," Rockset CEO Venkat Venkataramani says in a Rockset blog post. "We'll be helping OpenAI solve the hard database problems that AI apps face at massive scale." Venkataramani says that current Rockset customers won't experience "immediate change" and that the company will gradually transition them off the platform. "Some" members of Rockset's team will move over to OpenAI, Bloomberg says.

Hacker Claims To Have 30 Million Customer Records From Ticket Giant TEG

Par : BeauHD
21 juin 2024 à 22:20
An anonymous reader quotes a report from TechCrunch: A hacker is advertising customer data allegedly stolen from the Australia-based live events and ticketing company TEG on a well-known hacking forum. On Thursday, a hacker put up for sale the alleged stolen data from TEG, claiming to have information of 30 million users, including the full name, gender, date of birth, username, hashed passwords, and email addresses. In late May, TEG-owned ticketing company Ticketek disclosed a data breach affecting Australian customers' data, "which is stored in a cloud-based platform, hosted by a reputable, global third party supplier." The company said that "no Ticketek customer account has been compromised," thanks to the encryption methods used to store their passwords. TEG conceded, however, that "customer names, dates of birth and email addresses may have been impacted" -- data that would line up with that advertised on the hacking forum. The hacker included a sample of the alleged stolen data in their post. TechCrunch confirmed that at least some of the data published on the forum appears legitimate by attempting to sign up for new accounts using the published email addresses. In a number of cases, Ticketek's website gave an error, suggesting the email addresses are already in use. There's evidence that the company's "cloud-based platform" provider is Snowflake, "which has been at the center of a recent series of data thefts affecting several of its customers, including Ticketmaster, Santander Bank, and others," notes TechCrunch. "A now-deleted post on Snowflake's website from January 2023 was titled: 'TEG Personalizes Live Entertainment Experiences with Snowflake.' In 2022, consulting company Altis published a case study (PDF) detailing how the company, working with TEG, 'built a modern data platform for ingesting streaming data into Snowflake.'"

Stability AI Appoints New CEO

British startup Stability AI has appointed Prem Akkaraju as its new CEO. The 51-year-old Akkaraju, former CEO of visual effects company Weta Digital, "is part of a group of investors including former Facebook President Sean Parker that has stepped in to save Stability with a cash infusion that could result in a lower valuation for the firm," reports the Information (paywalled). "The new funding will likely shrink the stakes of some existing investors, who have collectively contributed more than $100 million." In March, Stability AI founder and CEO Emad Mostaque stepped down from the role to pursue decentralized AI. "In a series of posts on X, Mostaque opined that one can't beat 'centralized AI' with more 'centralized AI,' referring to the ownership structure of top AI startups such as OpenAI and Anthropic," reported TechCrunch at the time. The move followed a report in April that claimed the company ran out of cash to pay its bills for its rented cloud GPUs. Last year, the company raised millions at a $1 billion valuation.

Ontario Science Center To Close Immediately Over Roof Collapse Risk

Par : BeauHD
21 juin 2024 à 21:20
The Ontario Science Center, a world-class science and cultural institution in Toronto, is shutting down immediately due to the risk that the building's roof could collapse, the province announced Friday. CBC News: The abrupt closure, which the province says could last years, comes after the government's controversial announcement in 2023 that the popular landmark and attraction would be moved to the Ontario Place site -- a move it says will save costs. "The actions taken today will protect the health and safety of visitors and staff," said Infrastructure Minister Kinga Surma in a news release. "We are making every effort to avoid disruption to the public and help the Ontario Science Centre continue delivering on its mandate." An engineering report this week by Rimkus Consulting Group showed each of the centre's three buildings contain roof panels in a "distressed, high-risk" condition, the Ministry of Infrastructure said in a news release. The panels require fixing by Oct. 31, 2024 to "avoid further stress due to potential snow load which could lead to roof panel failure," the release said. Fixing the roof will cost between $22 million and $40 million, the ministry said, requiring the centre be closed for up to two years. "These estimates are incomplete and subject to change," said the ministry, noting the costs make up only a "small portion" of the funding needed to keep the science centre open. The government says the centre needs $478 million to tackle its "failing infrastructure" and sustain programming.

TikTok Confirms It Offered US Government a 'Kill Switch'

TikTok revealed it offered the U.S. government a "kill switch" in 2022 to address data protection and national security concerns, allowing the government to shut down the platform if it violated certain rules. The disclosure was made as it began its legal fight against legislation that will require ByteDance to divest TikTok's U.S. assets or face a ban. The BBC reports: "This law is a radical departure from this country's tradition of championing an open Internet, and sets a dangerous precedent allowing the political branches to target a disfavored speech platform and force it to sell or be shut down," they argued in their legal submission. They also claimed the US government refused to engage in any serious settlement talks after 2022, and pointed to the "kill switch" offer as evidence of the lengths they had been prepared to go. TikTok says the mechanism would have allowed the government the "explicit authority to suspend the platform in the United States at the US government's sole discretion" if it did not follow certain rules. A draft "National Security Agreement", proposed by TikTok in August 2022, would have seen the company having to follow rules such as properly funding its data protection units and making sure that ByteDance did not have access to US users' data. The "kill switch" could have been triggered by the government if it broke this agreement, it claimed. In a letter - first reported by the Washington Post - addressed to the US Department of Justice, TikTok's lawyer alleges that the government "ceased any substantive negotiations" after the proposal of the new rules. The letter, dated 1 April 2024, says the US government ignored requests to meet for further negotiations. It also alleges the government did not respond to TikTok's invitation to "visit and inspect its Dedicated Transparency Center in Maryland."

AT&T Can't Hang Up On Landline Phone Customers, California Agency Rules

Par : BeauHD
21 juin 2024 à 20:20
An anonymous reader quotes a report from Ars Technica: The California Public Utilities Commission (CPUC) yesterday rejected AT&T's request to end its landline phone obligations. The state agency also urged AT&T to upgrade copper facilities to fiber instead of trying to shut down the outdated portions of its network. AT&T asked the state to eliminate its Carrier of Last Resort (COLR) obligation, which requires it to provide landline telephone service to any potential customer in its service territory. A CPUC administrative law judge recommended rejection of the application last month, and the commission voted to dismiss AT&T's application with prejudice on Thursday. "Our vote to dismiss AT&T's application made clear that we will protect customer access to basic telephone service... Our rules were designed to provide that assurance, and AT&T's application did not follow our rules," Commissioner John Reynolds said in a CPUC announcement. State rules require a replacement COLR in order to relieve AT&T of its duties, and AT&T argued that VoIP and mobile services could fill that gap. But residents "highlighted the unreliability of voice alternatives" at public hearings, the CPUC said. "Despite AT&T's contention that providers of voice alternatives to landline service -- such as VoIP or mobile wireless services -- can fill the gap, the CPUC found AT&T did not meet the requirements for COLR withdrawal," the agency said. "Specifically, AT&T failed to demonstrate the availability of replacement providers willing and able to serve as COLR, nor did AT&T prove that alternative providers met the COLR definition." The administrative law judge's proposed decision said AT&T falsely claimed that commission rules require it "to retain outdated copper-based landline facilities that are expensive to maintain." The agency stressed that its rules do not prevent AT&T from upgrading to fiber. "COLR rules are technology-neutral and do not distinguish between voice services offered... and do not prevent AT&T from retiring copper facilities or from investing in fiber or other facilities/technologies to improve its network," the agency said yesterday. AT&T California President Marc Blakeman said the company is lobbying to change the state law. "No customer will be left without voice and 911 services. We are focused on the legislation introduced in California, which includes important protections, safeguards, and outreach for consumers and does not impact our customers in rural locations. We are fully committed to keeping our customers connected while we work with state leaders on policies that create a thoughtful transition that brings modern communications to all Californians," Blakeman said. According to SFGATE, the legislation pushed by AT&T "would create a way for AT&T to remain as COLR in rural regions, which the company estimates as being about 100,000 customers, while being released from COLR obligations everywhere else."

Public Servants Uneasy As Government 'Spy' Robot Prowls Federal Offices

Par : BeauHD
21 juin 2024 à 13:00
An anonymous reader quotes a report from CBC News: A device federal public servants call "the little robot" began appearing in Gatineau office buildings in March. It travels through the workplace to collect data using about 20 sensors and a 360-degree camera, according to Yahya Saad, co-founder of GlobalDWS, which created the robot. "Using AI on the robot, the camera takes the picture, analyzes and counts the number of people and then discards the image," he said. Part of a platform known as VirBrix, the robot also gathers information on air quality, light levels, noise, humidity, temperature and even measures CO2, methane and radon gas. The aim is to create a better work environment for humans -- one that isn't too hot, humid or dim. Saad said that means more comfortable and productive employees. The technology can also help reduce heating, cooling and hydro costs, he said. "All these measures are done to save on energy and reduce the carbon footprint," Saad explained. After the pilot program in March, VirBrix is set to return in July and October, and the government hasn't ruled out extending its use. It's paying $39,663 to lease the robot for two years. Bruce Roy, national president of the Government Services Union, called the robot's presence in federal workplaces "intrusive" and "insulting." "People feel observed all the time," he said in French. "It's a spy. The robot is a spy for management." Roy, whose union represents more than 12,000 federal workers across several departments, said the robot is unnecessary because the employer already has ways of monitoring employee attendance and performance. "We believe that one of the robot's tasks is to monitor who is there and who is not," he said. "Folks say, why is there a robot here? Doesn't my employer trust that I'm here and doing my work properly?" [...] Jean-Yves Duclos, the minister of public services and procurement, said the government is instead using the technology as it looks to cut its office space footprint in half over the coming years. "These robots, as we call them, these sensors observe the utilization of office space and will be able to give us information over the next few years to better provide the kind of workplace employees need to do their job," Duclos said in French. "These are totally anonymous methods that allow us to evaluate which spaces are the most used and which spaces are not used, so we can better arrange them." "In those cases we keep the images, but the whole body, not just the face, the whole body of the person is blurred," said Saad. "These are exceptional cases where we need to keep images and then the images would be handed over to the client." The data is then stored on a server on Canadian soil, according to GlobalDWS.

Meta has released the Threads API for developers to build "unique integrations" into the text-based conversation app. The move could potentially result in third-party apps. The Verge reports: "People can now publish posts via the API, fetch their own content, and leverage our reply management capabilities to set reply and quote controls, retrieve replies to their posts, hide, unhide or respond to specific replies," explains Jesse Chen, director of engineering at Threads. Chen says that insights into Threads posts are "one of our top requested features for the API," so Meta is allowing developers to see the number of views, likes, replies, reposts, and quotes on Threads posts through the API. Meta has published plenty of documentation about how developers can get started with the Threads API, and there's even an open-source Threads API sample app on GitHub.

Mathematician Reveals 'Equals' Has More Than One Meaning In Math

Par : BeauHD
21 juin 2024 à 07:00
"It turns out that mathematicians actually can't agree on the definition of what makes two things equal, and that could cause some headaches for computer programs that are increasingly being used to check mathematical proofs," writes Clare Watson via ScienceAlert. The issue has prompted British mathematician Kevin Buzzard to re-examine the concept of equality to "challenge various reasonable-sounding slogans about equality." The research has been posted on arXiv. From the report: In familiar usage, the equals sign sets up equations that describe different mathematical objects that represent the same value or meaning, something which can be proven with a few switcharoos and logical transformations from side to side. For example, the integer 2 can describe a pair of objects, as can 1 + 1. But a second definition of equality has been used amongst mathematicians since the late 19th century, when set theory emerged. Set theory has evolved and with it, mathematicians' definition of equality has expanded too. A set like {1, 2, 3} can be considered 'equal' to a set like {a, b, c} because of an implicit understanding called canonical isomorphism, which compares similarities between the structures of groups. "These sets match up with each other in a completely natural way and mathematicians realised it would be really convenient if we just call those equal as well," Buzzard told New Scientist's Alex Wilkins. However, taking canonical isomorphism to mean equality is now causing "some real trouble," Buzzard writes, for mathematicians trying to formalize proofs -- including decades-old foundational concepts -- using computers. "None of the [computer] systems that exist so far capture the way that mathematicians such as Grothendieck use the equal symbol," Buzzard told Wilkins, referring to Alexander Grothendieck, a leading mathematician of the 20th century who relied on set theory to describe equality. Some mathematicians think they should just redefine mathematical concepts to formally equate canonical isomorphism with equality. Buzzard disagrees. He thinks the incongruence between mathematicians and machines should prompt math minds to rethink what exactly they mean by mathematical concepts as foundational as equality so computers can understand them. "When one is forced to write down what one actually means and cannot hide behind such ill-defined words," Buzzard writes. "One sometimes finds that one has to do extra work, or even rethink how certain ideas should be presented."

Researchers Still Fighting For MDMA Therapy After FDA Advisors Vote Against It

Par : BeauHD
21 juin 2024 à 03:30
An anonymous reader quotes a report from the BBC: A vote against using MDMA as part of therapy for PTSD has provoked a powerful backlash among researchers who study psychedelic drugs. Some 13 million Americans struggle with post-traumatic stress disorder (PTSD). Existing therapies only bring relief for a fraction of patients, and new treatments are sorely needed, according to psychiatrists wrestling with the scale of the problem. So, there was distinct disappointment when an advisory committee at the US Food and Drug Administration (FDA) voted earlier this month against a therapy that many had hoped could offer the first new treatment for PTSD in 25 years. A number of experts who study psychedelics have since spoken out in support of MDMA-assisted therapy for PTSD and have sharply criticized the recommendations of the FDA's Psychopharmacological Drugs Advisory Committee. But some are still optimistic that the treatment might be approved when the FDA delivers its final decision in August. While MDMA, also commonly known as ecstasy or molly, is listed as a Schedule 1 controlled substance in the US and so is illegal to use outside research, there has been a growing number of studies suggesting that when used with psychotherapy it could have potential for treating PTSD and some other mental health conditions. Ahead of the meeting, FDA approval of MDMA-assisted therapy for PTSD seemed likely, says Sandeep Nayak, an assistant professor of psychiatry at Johns Hopkins University, who investigates psychedelics as treatments for substance use and mood disorders. About two-thirds of people who received three sessions of MDMA and talk therapy no longer qualified for a PTSD diagnosis at the end of two Phase 3 clinical trials. It's an outcome that is "almost double that of existing medications", says Gul Dolen, a neuroscientist at the University of California, Berkeley, who researches the mechanisms of how psychedelics achieve therapeutic effects. "What's more, [the treatment] led to durable improvements in these patients lasting at least six months." About half of people who enroll in current gold standard PTSD treatments drop out, which is "absurd," says Loree Sutton, a psychiatrist and retired Brigadier General in the US Army. She says new treatments are essential. "We have to do better." "Even if there are risks, we've got to figure this out, because we cannot not let this treatment be available," adds Rachel Yehuda, a professor of psychiatry and neuroscience at the Icahn School of Medicine at Mount Sinai who has conducted studies on the effects of MDMA-assisted therapy for PTSD. "Without it, we're just leaving too many people in suffering that they don't need to be in, and that is not right." The FDA is currently considering an application from California-based drug company Lykos Therapeutics for using MDMA capsules taken in conjunction with therapy in the treatment of PTSD. In the recent FDA advisory meeting, committee members cited apparent flaws in study design and data collection. The nine-hour hearing concluded with committee members voting 9-2 that the available data do not show "that the drug is effective" for PTSD, and voting 10-1 that the benefits of MDMA do not outweigh the risks.

IBM, Kyndryl Sued For Age Discrimination By Its Own VPs

Par : BeauHD
21 juin 2024 à 01:50
Thomas Claburn reports via The Register: Once again, IBM has been sued for age discrimination, this time alongside spin-off Kyndryl, for allegedly cutting the jobs of older workers while creating similar positions for younger ones. The complaint [PDF] was filed on Tuesday in New York City, on behalf of five veteran executives and employees who collectively served the two corporations for more than 150 years. The IBM plaintiffs include: Michael Nolan, former Director of Strategy and Planning for IBM's Software Unit; Karla Bousquet, former VP, CEO of Events at IBM, Karla; Jay Zeltzer, former Business Automation Leader; and Teresa Cook, former VP of Client Experience. Randall Blanchard, former Services Account manager, is suing Kyndryl, having previously been with Big Blue. Despite IBM chief global HR officer Nickel LaMoreaux's 2022 rejection of what she characterized as "false claims of systemic age discrimination," the lawsuit argues the mainframe titan is still targeting older workers. The legal filing cites a 2021 case, Townsley v. Int'l Bus. Machines Corp, in which executive Sam Ladah, who is accused of attempting "to keep ageist IBM executive level planning documents confidential," said those documents from five to six years earlier were still being used for hiring decisions. To further support the claim that the targeting of older workers continues to this day, the complaint says, "A recently leaked video of [CEO Arvind] Krishna confirms that IBM has continued its practice of using secretive top-down pressure to gerrymander its workforce to reflect the demographic preferences of its executives." The 2023 video, published by conservative political activist James O'Keefe, appears to show Krishna tying manager bonuses to diversity targets in a context where such targets are alleged to be discriminatory. Basically, IBM has been accused of threatening to withhold bonuses from bosses if they don't hire a diverse enough range of techies -- more Hispanic and Black people -- leading to qualified candidates -- Asian people and others -- being ignored on the basis of their race. The latest lawsuit also points to Wimbish v. IBM, an age discrimination complaint filed in September by two human resources managers. "In their complaint, these fired HR managers alleged that IBM's HR still constantly consider an employee's 'runway' when determining if that worker would be terminated," the complaint says. "'Runway' is coded language for how long IBM HR expects an employee to remain at IBM before they retire, a direct proxy for age."

Sweden Rejects a New Electrical Interconnection With Germany

Par : BeauHD
21 juin 2024 à 01:10
sonlas writes: Germany's energy transition plan includes extensive interconnection projects to distribute its intermittent renewable energy production. However, these projects face significant challenges. The latest example is Sweden. One such project, Hansa PowerBridge, announced in 2017, intended to link Germany and Sweden via a 300 km HVDC line through the Baltic Sea. This 700 MW project, estimated at 600 million euro, aimed to stabilize Germany's volatile electricity prices. However, on June 14, 2024, Sweden rejected the project, citing incompatibility between the countries' electricity systems. The connection would link northern Germany to southern Sweden, an area with insufficient infrastructure. Concerns also arose about the volatile German market disrupting Sweden's and increasing local prices. Energy Minister Ebba Busch justified this decision by saying the German market is currently not efficient enough and a connection would risk leading to higher prices and a more unstable electricity market in southern Sweden. This highlights the difficulty Germany faces with its Energiewende, or energy transition model. This model leads to erratic electricity price behaviors and significant challenges in balancing production capacities. While a possible solution for Germany lies in interconnection with neighboring countries, the examples of Norway (which cancelled the NorGer project too) and Sweden show that from the perspective of these neighbors, it looks more like an "export of German problems" rather than a solution.

500,000 Books Have Been Deleted From the Internet Archive's Lending Library

The Internet Archive's Open Library, which operates similarly to traditional libraries by lending out digital copies of purchased or donated physical books, has been forced to remove 500,000 books due to a lawsuit by big publishers. Mike Masnick reports via Techdirt: As we've discussed at great length, the Internet Archive's Open Library system is indistinguishable from the economics of how a regular library works. The Archive either purchases physical books or has them donated (just like a physical library). It then lends them out on a one-to-one basis (leaving aside a brief moment where it took down that barrier when basically all libraries were shut down due to pandemic lockdowns), such that when someone "borrows" a digital copy of a book, no one else can borrow that same copy. And yet, for all of the benefits of such a system in enabling more people to be able to access information, without changing the basic economics of how libraries have always worked, the big publishers all sued the Internet Archive. The publishers won the first round of that lawsuit. And while the court (somewhat surprisingly!) did not order the immediate closure of the Open Library, it did require the Internet Archive to remove any books upon request from publishers (though only if the publishers made those books available as eBooks elsewhere). As the case has moved into the appeals stage (where we have filed an amicus brief), the Archive has revealed that around 500,000 books have been removed from the open library. The Archive has put together an open letter to publishers, requesting that they restore access to this knowledge and information -- a request that will almost certainly fall on extremely deaf ears: "We purchase and acquire books -- yes, physical, paper books -- and make them available for one person at a time to check out and read online. This work is important for readers and authors alike, as many younger and low-income readers can only read if books are free to borrow, and many authors' books will only be discovered or preserved through the work of librarians. We use industry-standard technology to prevent our books from being downloaded and redistributed -- the same technology used by corporate publishers. But the publishers suing our library say we shouldn't be allowed to lend the books we own. They have forced us to remove more than half a million books from our library, and that's why we are appealing."

SUSE Upgrades Its Distros With 19 Years of Support

An anonymous reader quotes a report from ZDNet: At SUSECon in Berlin, SUSE, a global Linux and cloud-native software leader, announced significant enhancements across its entire Linux distribution family. These new capabilities focus on providing faster time-to-value and reduced operational costs, emphasizing the importance of choice in today's complex IT landscape. SUSE Linux Enterprise Server (SLES) 15 Service Pack (SP) 6 is at the heart of these upgrades. This update future-proofs IT workloads with a new Long Term Service (LTS) Pack Support Core. How long is long-term? Would you believe 19 years? This gives SLES the longest-term support period in the enterprise Linux market. Even Ubuntu, for which Canonical recently extended its LTS to 12 years, doesn't come close. You may ask yourself, "Why 19 years?" SUSE General Manager of Business Critical Linux (BCL) Rick Spencer, explained in an interview that the reason is that on 03:14:08 Greenwich Mean Time (GMT, aka Coordinated Universal Time) Tuesday, January 19, 2038, we reach the end of computing time. Well, not really, but Linux, and all the other Unix-based operating systems, including some versions of MacOS, reach what's called the Epoch. That's when the time-keeping code in 32-bit Unix-based operating systems reaches the end of the seconds it's been counting since the beginning of time -- 00:00:00 GMT on January 1, 1970, as far as Linux and Unix systems are concerned -- and resets to zero. Just like the Y2K bug, that means that all unpatched 32-bit operating systems and software will have fits. The Linux kernel itself had the problem fixed in 2020's Linux 5.6 kernel, but many other programs haven't dealt with it. Until then, though, if you're still running SLES 15 SP6, you'll be covered. I strongly suggest upgrading before then, but if you want to stick with that distro to the bitter end, you can. The new SLES also boasts enhanced security features like confidential computing support with encryption in memory, utilizing Intel TDX and AMD SEV processors, along with remote attestation via SUSE Manager. Additionally, SLES for SAP Applications 15 SP6 offers a secure and reliable platform for running mission-critical SAP workloads, incorporating innovations from Trento to help system administrators avoid infrastructure issues.

X Window System Turns 40

Ancient Slashdot reader ewhac writes: On June 19, 1984, Robert Scheifler announced on MIT's Project Athena mailing list a new graphical windowing system he'd put together. Having cribbed a fair bit of code from the existing windowing toolkit called W, Scheifler named his new system X, thus giving birth to the X Window System. Scheifler prophetically wrote at the time, "The code seems fairly solid at this point, although there are still some deficiencies to be fixed up." The 1980's and 1990's saw tremendous activity in the development of graphical displays and user interfaces, and X was right in the middle of it all, alongside Apple, Sun, Xerox, Apollo, Silicon Graphics, NeXT, and many others. Despite the fierce, well-funded competition, and heated arguments about how many buttons a mouse should have, X managed to survive, due in large part to its Open Source licensing and its flexible design, allowing it to continue to work well even as graphical hardware rapidly advanced. As such, it was ported to dozens of platforms over the years (including a port to the Amiga computer by Dale Luck in the late 1980's). 40 years later, despite its warts, inconsistencies, age, and Wayland promising for the last ten years to be coming Real Soon Now, X remains the windowing system for UNIX-like platforms.
