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

Slashdot - Sun, 2024-11-17 09:34
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?

Slashdot - Sun, 2024-11-17 05:34
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

Slashdot - Sun, 2024-11-17 03:34
"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

Slashdot - Sun, 2024-11-17 00:59
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?

Slashdot - Sat, 2024-11-16 23:34
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

Slashdot - Sat, 2024-11-16 22:16
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...

An anonymous reader shared this report from the Verge: Bluesky might be on the rise, but Instagram and Threads boss Adam Mosseri wants you to know that Threads is still much bigger. In a post on Thursday, Mosseri said that Threads has gotten "more than 15 million signups in November alone," seemingly trying to throw some cold water over Bluesky crossing 15 million users total on Wednesday. Mosseri also reiterated that the platform has been getting more than a million signups per day — a stat that CEO Mark Zuckerberg revealed during last month's earnings call — and noted that the platform has been seeing that volume of signups for "going on three months." As November began, Mosseri posted that Threads had 275 million monthly active users....

ISS Astronauts are Safe. But NASA and Russia Disagree on How to Fix Leak

Slashdot - Sat, 2024-11-16 20:34
"NASA has emphasized the ISS crew is in no immediate danger," reports Space.com. "The leaking area in the Russian segment of the orbital complex has been ongoing for five years," and "there was a temporary increase in the leak rate that was patched earlier this year..." Former astronaut Bob Cabana emphasized that troubleshooting is ongoing during a brief livestreamed meeting on Wednesday. But NASA and Roscosmos "don't have a common understanding of what the likely root causes or the severity of the consequences of these leaks." "The Russian position is that the most probable cause of the cracks is high cycling caused by micro-vibrations," Cabana said, referring to flexing of metal and similar components that heat and cool as the ISS orbits in and out of sunlight. "NASA believes the PrK cracks are likely multi-causal — including pressure and mechanical stress, residual stress, material properties and environmental exposures," Cabana continued. NASA and Russia disagree about whether "continued operations are safe", he added, but the remedy for now is to keep the hatch closed between the U.S. and Russian side as investigations continue. The two agencies will continue meeting to seek "common understanding of the structural integrity", Cabana pledged, but he did not provide a timeline. Academic and industry experts will also be consulted.

'Automotive Grade Linux' Will Promote Open Source Program Offices for Automakers

Slashdot - Sat, 2024-11-16 19:34
Automotive Grade Linux is a collaborative open source project developing "an open platform from the ground up that can serve as the de facto industry standard" for fast development of new features. Automakers have joined with tech companies and suppliers to speed up development (and adoption) of "a fully open software stack for the connected car" — hosted at the Linux Foundation, and "with Linux at its core..." And this week they created a new Open Source Program Office expert group, led by Toyota, to promote the establishment of Open Source Program Offices within the automotive industry, "and encourage the sharing of information and best practices between them." Open source software has become more prevalent across the automotive industry as automakers invest more time and resources into software development. Automakers like Toyota and Subaru are using open source software for infotainment and instrument cluster applications. Other open source applications across the automotive industry include R&D, testing, vehicle-to-cloud and fleet management. "Historically, there has been little code contributed back to the open source community," said Dan Cauchy, Executive Director of Automotive Grade Linux. "Often, this was because the internal procedures or IT infrastructure weren't in place to support open source contributions. The rise of software-defined vehicles has led to a growing trend of automakers not just using, but also contributing, to open source software. Many organizations are also establishing Open Source Program Offices to streamline and organize open source activities to better support business goals." Automakers including Toyota, Honda, and Volvo have already established Open Source Program Offices. The new AGL OSPO Expert Group provides a neutral space for them to share pain points and collaborate on solutions, exchange information, and develop best practices that can help other automakers build their own OSPOs. "Toyota has been participating in AGL and the broader open source community for over a decade," said Masato Endo, Group Manager of Open Source Program Group, Toyota. "We established an OSPO earlier this year to promote the use of open source software internally and to help guide how and where we contribute. We are looking forward to working with other open source leaders to solve common problems, collaborate on best practices, and invigorate open source activities in the automotive industry." The AGL OSPO EG is led by Toyota with support from Panasonic and AISIN Corporation.

Does Casio's New Calculator Watch Take You Back To 6th Grade Math Class?

Slashdot - Sat, 2024-11-16 18:34
Slashdot reader jjslash brings word that Casio "has reintroduced its iconic calculator watch featuring a retro design with green text on a negative LCD and a classic keypad layout." TechSpot reports that the watch was based on the Casio Mini personal calculator first released in the early 1970s — even offering a keypad using the original fonts (with numbers separated by grid lines): Even the mode button, colored red, is a nod to the calculator's power indicator. The watches' calculator function can add, subtract, multiply, and divide up to eight digits. As for watch functions, you get dual time, an alarm, stopwatch functionality, and more... Casio's original personal calculator debuted in 1972, and cost $59.95. It featured a six-digit display, was a quarter the size of its competitors, and cost just a third of rival products. The calculator was an instant hit for Casio, selling a million units in the first 10 months on the market and more than six million units over the span of the series.

AI Lab PleIAs Releases Fully Open Dataset, as AMD, Ai2 Release Open AI Models

Slashdot - Sat, 2024-11-16 17:34
French private AI lab PleIAs "is committed to training LLMs in the open," they write in a blog post at Mozilla.org. "This means not only releasing our models but also being open about every aspect, from the training data to the training code. We define 'open' strictly: all data must be both accessible and under permissive licenses." Wednesday PleIAs announced they were releasing the largest open multilingual pretraining dataset, according to their blog post at HuggingFace: Many have claimed that training large language models requires copyrighted data, making truly open AI development impossible. Today, Pleias is proving otherwise with the release of Common Corpus (part of the AI Alliance Open Trusted Data Initiative) — the largest fully open multilingual dataset for training LLMs, containing over 2 trillion tokens of permissibly licensed content with provenance information (2,003,039,184,047 tokens). As developers are responding to pressures from new regulations like the EU AI Act, Common Corpus goes beyond compliance by making our entire permissibly licensed dataset freely available on HuggingFace, with detailed documentation of every data source. We have taken extensive steps to ensure that the dataset is high-quality and is curated to train powerful models. Through this release, we are demonstrating that there doesn't have to be such a [heavy] trade-off between openness and performance. Common Corpus is: — Truly Open: contains only data that is permissively licensed and provenance is documented — Multilingual: mostly representing English and French data, but contains at least 1B tokens for over 30 languages — Diverse: consisting of scientific articles, government and legal documents, code, and cultural heritage data, including books and newspapers — Extensively Curated: spelling and formatting has been corrected from digitized texts, harmful and toxic content has been removed, and content with low educational content has also been removed. Common corpus builds on a growing ecosystem of large, open datasets, such as Dolma, FineWeb, RefinedWeb. The Common Pile currently in preparation under the coordination of Eleuther is built around the same principle of using permissible content in English language and, unsurprisingly, there were many opportunities for collaborations and shared efforts. But even together, these datasets do not provide enough training data for models much larger than a few billion parameters. So in order to expand the options for open model training, we still need more open data... Based on an analysis of 1 million user interactions with ChatGPT, the plurality of user requests are for creative compositions... The kind of content we actually need — like creative writing — is usually tied up in copyright restrictions. Common Corpus tackles these challenges through five carefully curated collections... Last week AMD also released its first series of fully open 1 billion parameter language models, AMD OLMo. And last month VentureBeat reported that the non-profit Allen Institute for AI had unveiled Molmo, "an open-source family of state-of-the-art multimodal AI models which outpeform top proprietary rivals including OpenAI's GPT-4o, Anthropic's Claude 3.5 Sonnet, and Google's Gemini 1.5 on several third-party benchmarks."

Five-Year Prison Sentence for Man who Stole 120,000 Bitcoin from Bitfinex in 2016

Slashdot - Sat, 2024-11-16 16:34
More than 120,000 bitcoin were stolen in a 2016 breach of Bitfinex. Seven years later the perpetrator pleaded guilty. And Thursday he was sentenced to a five-year prison term, reports the Associated Press: Ilya Lichtenstein masterminded one of the largest-ever thefts from a virtual currency exchange before he and his wife, Heather Rhiannon Morgan, carried out an elaborate scheme to liquidate the stolen funds, according to federal prosecutors... "Over half a decade, the defendant engaged in what IRS agents described as the most complicated money laundering techniques they had seen to date," prosecutors wrote... The couple successfully laundered about 21 percent of the funds stolen from Bitfinex. The laundered money was worth at least $14 million at 2016 prices. Its value would have exceeded $1 billion at the time of their 2022 arrest. Authorities seized the remaining funds, collectively valued at over $6 billion at current prices... An attorney for Bitfinex said the hack "devastated" its finances and its reputation with its customers, with the stolen funds accounting for approximately 36% of the company's assets at the time of theft. "Bitfinex had to take unprecedented and immediate action to ensure that any losses from the Hack would ultimately be borne by Bitfinex and its shareholders alone, not its customers," the lawyer, Barry Berke, wrote in a letter to the judge. A prosecutor said Lichtenstein immediately began cooperating with federal authorities after his arrest, helping them with other cybercrime investigations. Over 96% of the stolen funds have been recovered, with help from Lichtenstein, according to defense attorney Samson Enzer. The "vast bulk" of the stolen money was never spent, the lawyer said. Lichtenstein also "pleaded with the judge to spare his wife from prison, blaming himself for her involvement," according to the article. His wife — a rap artist who records under the name Razzlekhan — will be sentenced Monday, but has pleaded guilty to the same charge, and prosecutors are recommending an 18-month sentence.

Samples Obtained By Chinese Spacecraft Show Moon's Ancient Volcanism

Slashdot - Sat, 2024-11-16 11:00
China's Chang'e-6 mission made history by retrieving the first surface samples from the moon's far side, revealing evidence of volcanic activity spanning 1.4 billion years. Reuters reports: Researchers said on Friday the soil brought back from the Chang'e-6 landing site contained fragments of volcanic rock - basalt - dating to 4.2 billion years ago and to 2.8 billion years ago. This points to a long period of volcanic activity - at least 1.4 billion years - on the far side during the first half of the moon's history, when it was a more dynamic world than it is today. The moon, like Earth, formed about 4.5 billion years ago. Volcanism on the moon, Earth and other planetary bodies involves the eruption of molten rock from the mantle - the layer just under the outer crust - onto the surface. The landing site in the South Pole-Aitken Basin, an impact crater, is an area with the thinnest crust on the moon, helpful for finding evidence of volcanism. The samples contained various volcanic rock fragments, and the researchers used a method called radioisotope dating to determine their age. Lunar basalt samples previously were obtained from the moon's near side, which perpetually faces Earth, during U.S. Apollo, Soviet Luna and Chinese Chang'e-5 missions. These showed that volcanism on the near side had occurred as long ago as 4.0 billion years ago and continued for at least two billion years, Li said. "The exact timing and duration of lunar volcanism is elusive and maybe varied across different regions. Some small-scale volcanism may have also occurred on the near side as late as about 120 million years ago as recorded by volcanic glass beads from Chang'e-5 samples" collected in 2020, Li said. The new study also found that the basalt dating to 4.2 billion years ago differed in composition from the basalt dating to 2.8 billion years ago, meaning they originated from different sources of molten rock - magma - in the mantle, Li said. The Chang'e-6 samples, Li said, also differ in composition compared with previously collected lunar samples from the near side.

Is NASA's Moon Rocket Getting Canceled?

Slashdot - Sat, 2024-11-16 08:00
"NASA has squandered $27 billion on the SLS moon rocket -- $6 billion over budget and 5 years late," writes longtime Slashdot reader schwit1. "The SLS isn't reusable so even if they finished it -- it is already obsolete. It is clear to everyone that the boondoggle has failed but the newest plan is to find a way to blame Trump. There is a big desire for big changes." Futurism reports: According to Ars Technica senior space reporter Eric Berger's insider sources, there's an "at least 50-50" chance that the rocket "will be canceled." "Not Block 1B. Not Block 2," he added, referring to the variant that was used during NASA's uncrewed Artemis I test flight in 2022 and a more powerful design with a much higher translunar injection payload capacity, respectively. "All of it." To be clear, as Berger himself points out, we're still far "from anything being settled." Nonetheless, the reporter's sources have historically been highly reliable, suggesting the space agency may indeed be getting cold feet about continuing to pour billions of dollars into the non-reusable rocket. [...] "Honestly the people who will ultimately make this decision aren't even in place yet," Berger wrote in a followup tweet, likely referring to the incoming Trump administration. "But there is a big desire for big changes."

With First Mechanical Qubit, Quantum Computing Goes Steampunk

Slashdot - Sat, 2024-11-16 04:30
An anonymous reader quotes a report from Science Magazine: Qubits, the strange devices at the heart of a quantum computer that can be set to 0, 1, or both at once, could hardly be more different from the mechanical clockwork used in the earliest computers. Today, most quantum computers rely on qubits made out of tiny circuits of superconducting metal, individual ions, photons, or other things. But now, physicists have made a working qubit from a tiny, moving machine, an advance that echoes back to the early 20th century when the first computers employed mechanical switches. "For many years, people were thinking it would be impossible to make a qubit from a mechanical system," says Adrian Bachtold, a condensed matter physicist at the Institute of Photonic Sciences who was not involved in the work, published today in Science. Stephan Durr, a quantum physicist at the Max Planck Institute for Quantum Optics, says the result "puts a new system on the map," which could be used in other experiments—and perhaps to probe the interface of quantum mechanics and gravity. [...] The new mechanical qubit is unlikely to run more mature competition off the field any time soon. Its fidelity -- a measure of how well experimenters can set the state they desire -- is just 60%, compared with greater than 99% for the best qubits. For that reason, "it's an advance in principle," Bachtold says. But Durr notes that a mechanical qubit might serve as a supersensitive probe of forces, such as gravity, that don't affect other qubits. And ETHZ researchers hope to take their demonstration a step further by using two mechanical qubits to perform simple logical operations. "That's what Igor is working on now," [says Yiwen Chu, a physicist at ETH Zurich]. If they succeed, the physical switches of the very first computers will have made a tiny comeback.

NSO, Not Government Clients, Operates Its Spyware

Slashdot - Sat, 2024-11-16 02:40
jojowombl shares a report from The Guardian: Legal documents released in ongoing US litigation between NSO Group and WhatsApp have revealed for the first time that the Israeli cyberweapons maker -- and not its government customers -- is the party that "installs and extracts" information from mobile phones targeted by the company's hacking software. The new details were contained in sworn depositions from NSO Group employees, portions of which were published for the first time on Thursday. It comes five years after WhatsApp, the popular messaging app owned by Facebook, first announced it was filing suit against NSO. The company, which was blacklisted by the Biden administration in 2021, makes what is widely considered the world's most sophisticated hacking software, which -- according to researchers -- has been used in the past in Saudi Arabia, Dubai, India, Mexico, Morocco and Rwanda. [...] At the heart of the legal fight was an allegation by WhatsApp that NSO had long denied: that it was the Israeli company itself, and not its government clients around the world, who were operating the spyware. NSO has always said that its product is meant to be used to prevent serious crime and terrorism, and that clients are obligated not to abuse the spyware. It has also insisted that it does not know who its clients are targeting. [...] To make its case, WhatsApp was allowed by Judge Phyllis Hamilton to make its case, including citing depositions that have previously been redacted and out of public view. In one, an NSO employee said customers only needed to enter a phone number of the person whose information was being sought. Then, the employee said, "the rest is done automatically by the system." In other words, the process was not operated by customers. Rather NSO alone decided to access WhatsApp's servers when it designed (and continuously upgraded) Pegasus to target individuals' phones. A spokesperson for NSO, Gil Lainer, said in a statement: "NSO stands behind its previous statements in which we repeatedly detailed that the system is operated solely by our clients and that neither NSO nor its employees have access to the intelligence gathered by the system. We are confident that these claims, like many others in the past, will be proven wrong in court, and we look forward to the opportunity to do so."

T-Mobile Hacked In Massive Chinese Breach of Telecom Networks

Slashdot - Sat, 2024-11-16 02:20
Chinese hackers, reportedly linked to a Chinese intelligence agency, breached T-Mobile as part of a broader cyber-espionage campaign targeting telecom companies to spy on high-value intelligence targets. "T-Mobile is closely monitoring this industry-wide attack, and at this time, T-Mobile systems and data have not been impacted in any significant way, and we have no evidence of impacts to customer information," a company spokesperson told the Wall Street Journal. Reuters reports: It was unclear what information, if any, was taken about T-Mobile customers' calls and communications records, according to the report. On Wednesday, The Federal Bureau of Investigation (FBI) and the U.S. cyber watchdog agency CISA said China-linked hackers have intercepted surveillance data intended for American law enforcement agencies after breaking into an unspecified number of telecom companies.

Chegg, Down From $12 Billion To $159 Million In Value, Lays Off Hundreds; CEO Blames Google and AI

Slashdot - Sat, 2024-11-16 02:00
Chegg, the online education company, is laying off 319 workers as it struggles to compete against modern AI chatbots. SFGATE reports: Chegg announced the new layoff round, which will hit 21% of its workforce, in a filing with the Securities and Exchange Commission on Tuesday. The company delivered the news alongside another brutal quarterly financial report; Chegg lost more than $212 million from July through September. CEO Nathan Schultz, in prepared remarks accompanying the report, expressed some optimism but called it a "trying time" for his company. Chegg provides grammar and plagiarism checkers, plus course-by-course study help, along with much-used textbook solution guides. "Technology shifts have created headwinds for our industry and Chegg's business specifically," Schultz said. "Recent advancements in the AI search experience and the adoption of free and paid generative AI services by students, have resulted in challenges for Chegg. These factors are adversely affecting our business outlook and are requiring us to refocus and adjust the size of our business." He specifically called out Google's AI overviews, a recent change to search results that pulls information from news outlets and sites like Chegg and summarizes above the classic blue links. Schultz said that his team believes Google is "shifting from being a search origination point to the destination" in an attempt to keep market share. Schultz also blamed generative AI chatbots like OpenAI's ChatGPT, saying that students see the tool and others like it as "strong alternatives" to Chegg. Web traffic has dropped sharply as a result, Schultz wrote. A Wall Street Journal story published Saturday said Chegg "is trying to avoid becoming [ChatGPT's] first major victim" and that the company had lost more than 500,000 subscribers, some who paid almost $20 a month, since the chatbot's 2022 launch. Despite the negative business impact, it seems Chegg is experimenting with new tech. Schultz said in the remarks that the company had formed an "arena" to evaluate AI models and aims to "integrate AI into the full learning journey."

Bluesky Says It Won't Train AI On Your Posts

Slashdot - Sat, 2024-11-16 01:20
Bluesky, the social network surging in popularity, says it has "no intention" of training AI tools on users content. "The social network made the announcement on the same day that X (formerly Twitter) is implementing its new terms of service that allow the platform to use public posts to train AI," notes TechCrunch. From the report: "A number of artists and creators have made their home on Bluesky, and we hear their concerns with other platforms training on their data," Bluesky said in a post on its app. "We do not use any of your content to train generative AI, and have no intention of doing so." The company went on to note that it uses AI internally to help with content moderation and that it also uses the technology in its "Discover" algorithmic feed. However, Bluesky says "none of these are Gen AI systems trained on user content."

Once Worth $7.3 Billion, Grubhub Sells For Just $650 Million

Slashdot - Sat, 2024-11-16 00:40
An anonymous reader quotes a report from CNN: Europe's biggest meal delivery firm, Just Eat Takeaway, said on Wednesday it had struck a deal to sell its U.S. unit Grubhub to Wonder for $650 million, sending its shares soaring 20% in early trading. The Amsterdam-listed company had been looking to offload Chicago-based Grubhub since as early as 2022, after acquiring it in 2020 in a $7.3 billion deal amid a pandemic-driven boom in delivery services -- a process that was hampered by slowing growth, high taxes and a question of fee caps in New York City. "Just Eat Takeaway is at last putting an end to its disastrous U.S. journey," Bryan Garnier analyst Clement Genelot said, noting the group had destroyed more than $7 billion in shareholder value there. Grubhub's enterprise value of $650 million includes $500 million of senior notes and $150 million cash, Wonder said in a statement. Wonder is a food-delivery startup led by former Walmart executive Marc Lore.
