The Quest To Build a Telescope On the Moon

Par : msmash
24 septembre 2024 à 17:37
silverjacket writes: A feature for The New Yorker describes a plan to use robots to mine lunar materials and build a radio telescope on the far side of the moon that will help answer questions about the early universe. An excerpt from the story: he dream of a lunar telescope dates to the nineteen-sixties. The moon has the advantage of being hundreds of thousands of miles away from earthly electronics; on the far side of the moon, in particular, there's virtually no noise from human technology or the Earth's magnetosphere. After the Apollo landings, however, interest in the moon waned. Jack Burns, an astrophysicist who is now at the University of Colorado Boulder, has been advocating for a moon-based telescope since 1984. "I never, never would have guessed that it would take this long," he told me. "I just won't accept no for an answer." Today, Burns is the chief scientist of FarView, as well as the primary investigator of a sort of mini-FarView: FARSIDE, which would have one or two hundred antennas instead of a hundred thousand. If FarView is built, it would be able to detect some of the oldest light in existence. The universe began 13.8 billion years ago as a dense, fast-expanding soup of matter and energy; around three hundred and eighty thousand years later, it had cooled enough for hydrogen atoms to hold together. After that came the Cosmic Dark Ages: millions of years without stars or galaxies, a period we know very little about. But hydrogen occasionally releases light with a wavelength of twenty-one centimetres -- radio waves. Some of that light is still around. Because twenty-one-centimetre radiation is stretched by the steady expansion of the universe -- it's now tens to hundreds of metres long -- scientists can figure out how old it is, and how far away. (The longer the wavelength, the older the light and the more distant its source.) This means that if scientists can build a radio telescope on the moon, they will be able to create a three-dimensional picture of the early universe.

Low-Lying Pacific Islands Pin Hopes on UN Meeting as Sea Rise Threatens Survival

An anonymous reader shares a report: The Pacific country of Kiribati might be surrounded by water, but on land its population is running dry. The ocean around them is steadily encroaching, contaminating underground wells and leeching salt into the soil. "Our waters have been infected," climate activist and law student Christine Tekanene says. "Those who are affected, they now can't survive with the water that changed after sea level rise." The freshwater crisis is just one of the many threats driven by rising seas in Kiribati. Its people live on a series of atolls, peaking barely a couple of metres above a sprawling tract of the Pacific Ocean. As global temperatures rise and ice sheets melt, Kiribati -- and other low-lying nations like it -- are experiencing extreme and regular flooding, frequent coastal erosion and persistent food and water insecurity. This week the United Nations general assembly will hold a high-level meeting to address the existential threats posed by sea level rise as the issue climbs the international agenda; last year the UN security council debated it for the first time. Wednesday's meeting aims to build political consensus on action to address the widespread social, economic and legal consequences of rising seas. Samoa's UN representative, Fatumanava Dr Pa'olelei Luteru, says the upcoming UN meeting is long overdue and "extremely important" for island nations. "Economically, militarily, we're not powerful," says Luteru, who also serves as the current chair of the Alliance of Small Island States (AOSIS). "At least within the context of the UN and the multilateral system we have the possibility and the opportunity to engage and achieve some of the things that are a priority for us."

An anonymous reader shares a report: The alleged Iranian hack of Donald Trump's orbit continued at least until mid-September and may be ongoing, a document the hackers shared with a progressive publication reveals. Iranian authorities have denied any involvement in the efforts to leak internal documents from Trump's campaign, which have reportedly been sent to major US publications including Politico and The New York Times, and to the Biden campaign. But the campaign and outside analysts have blamed the hack on the Iranians, who have ample reasons for hostility to the former president and also allegedly plotted his assassination. The publisher of the newsletter Popular Information, Judd Legum, writes this morning that a source under the name "Robert" shared a set of documents with him. Those included a research dossier on JD Vance matching other publications' descriptions of the hacked material. But the leak also included a legal letter to The New York Times complaining about an article that raised questions about the validity of Trump's image as a successful businessman.

WordPress hosting service WP Engine on Monday sent a cease-and-desist letter to Automattic after the latter's CEO Matt Mullenweg called WP Engine a "cancer to WordPress" last week. From a report: The notice asks Automattic and Mullenweg to retract their comments and stop making statements against the company. WP Engine, which (like Automattic itself) commercializes the open-source WordPress project, also accused Mullenweg of threatening WP Engine before the WordCamp summit held last week. "Automattic's CEO Matthew Mullenweg threatened that if WP Engine did not agree to pay Automattic -- his for-profit entity -- a very large sum of money before his September 20th keynote address at the WordCamp US Convention, he was going to embark on a self-described 'scorched earth nuclear approach' toward WP Engine within the WordPress community and beyond, the letter read. "When his outrageous financial demands were not met, Mr. Mullenweg carried out his threats by making repeated false claims disparaging WP Engine to its employees, its customers, and the world," the letter added.

Google is getting ready to show off updated Street View imagery in nearly 80 countries. The Verge: In a now-removed blog post seen by The Verge, Google announced that the new images are coming to countries like Australia, Brazil, Denmark, Japan, the Philippines, Rwanda, Serbia, South Africa, and more. Google is also bringing Street View to a handful of countries where it's never been available, including Bosnia, Namibia, Lichtenstein, and Paraguay. The company said its more portable Street View camera, which launched in 2022, will help offer images of "even more places in the future." Google Maps and Google Earth are getting sharper satellite imagery as well, thanks to the company's cloud-removal AI tool that takes out clouds, shadows, haze, and mist. This should result in "brighter, more vibrant" images, according to Google.

24 septembre 2024 à 14:00
Speaking of California, its governor Gavin Newsom has signed into law a a bill that requires schools to limit or ban the use of smartphones, amid a growing consensus that excess usage can increase the risk of mental illness and impair learning. From a report: Thirteen other states this year have banned or restricted cellphones in school or recommended local educators do so, after Florida led the way by banning phones in class in 2023, according to Education Week. California, with nearly 5.9 million public school students, has followed the lead of its own Los Angeles County, whose school board banned smartphones for its 429,000 students in June. That same month U.S. Surgeon General Vivek Murthy called for a warning label on social media platforms, akin to those on cigarette packages, likening the problem to a mental health emergency. Murthy cited a study in the medical journal JAMA showing adolescents who spend more than three hours a day on social media may be at heightened risk of mental illness, while referring to a Gallup poll showing the average teen spends 4.8 hours per day on social media. California's bill, which passed 76-0 in the state assembly and 38-1 in the senate, requires school boards or other governing bodies to develop a policy to limit or prohibit student use of smartphones on campus by July 1, 2026, and update the policy every five years.

joshuark shares a report: Microsoft has officially announced that Windows Server Update Services (WSUS) is now deprecated, but plans to maintain current functionality and continue publishing updates through the channel. This move isn't surprising, as Microsoft first listed WSUS as one of the "features removed or no longer developed starting with Windows Server 2025" on August 13. In June, the company also revealed that it would also soon deprecate WSUS driver synchronization. While new features and development for WSUS will cease, Microsoft said today that it plans to continue supporting the service's existing functionality and updates, which will still be distributed, even after deprecation. "Specifically, this means that we are no longer investing in new capabilities, nor are we accepting new feature requests for WSUS," Microsoft's Nir Froimovici said on Friday. "However, we are preserving current functionality and will continue to publish updates through the WSUS channel. We will also support any content already published through the WSUS channel."

Some Kaspersky Customers Receive Surprise Forced-Update To New Antivirus Software

23 septembre 2024 à 20:55
Customers of Kaspersky antivirus in the United States found out in the last few days that their cybersecurity software was automatically replaced with a new one called UltraAV, according to several customers. And while Kaspersky said earlier this month that its U.S. customers would be transitioned to UltraAV, many of its customers said they had no idea this was going to happen and that it would automatically be forced upon them. From a report: "Woke up to Kasperky [sic] completely gone from my system with Ultra AV and Ultra VPN freshly installed (not by me, just automatically while I slept)," a user on Reddit wrote. Others reported having the same experience in the same Reddit thread, as well as in other threads. A reseller, who until recently sold Kaspersky products prior to the recent sales ban, told TechCrunch that he was left "annoyed" by the move to automatically remove Kaspersky software and replace it with an entirely different antivirus. A former senior U.S. government cybersecurity official said that this was an example of the "huge risk" posed by the access granted by Kaspersky software. It's worth noting that, on the other hand, other customers did report receiving an email from Kaspersky about the transition to UltraAV.

Government of Bhutan Holds Over $825 Million, or Nearly a Third of Its GDP, in Bitcoin, Arkham Data Shows

Par : msmash
23 septembre 2024 à 20:05
The government of Bhutan is currently holding over $828 million in bitcoin, according to onchain data by Arkham Intelligence. From a report: "Unlike most governments, Bhutan's BTC does not come from law enforcement asset seizures, but from bitcoin mining operations, which have ramped up dramatically since early 2023," the crypto intelligence firm explained. Crypto intelligence firm Arkham highlighted the Kingdom of Bhutan's bitcoin holdings on social media platform X last week. Bhutan is a small, landlocked kingdom located in the eastern Himalayas, bordered by China to the north and India to the south. The country currently has a population of less than 800,000 people. We learned last year that Bhutan had been secretly mining bitcoin using its abundant hydroelectric resources since around 2019. The operation, which began when bitcoin was priced at approximately $5,000, aims to harness the country's vast renewable energy reserves to power mining rigs. Hydroelectricity already accounts for 30% of Bhutan's GDP and powers nearly all of its 800,000 residents. The government claimed last year that mining profits are used to subsidize power and hardware costs. This revelation makes Bhutan one of the few countries globally to run a state-owned bitcoin mine, alongside El Salvador. At over $800 million in Bitcoin holdings, the reserve accounts for nearly a third of Bhutan's 2022-calculated GDP.

Earth May Have Breached Seven of Nine Planetary Boundaries, Health Check Shows

Industrial civilisation is close to breaching a seventh planetary boundary, and may already have crossed it, according to scientists who have compiled the latest report on the state of the world's life-support systems. From a report: "Ocean acidification is approaching a critical threshold," particularly in higher-latitude regions, says the latest report on planetary boundaries. "The growing acidification poses an increasing threat to marine ecosystems." The report, from the Potsdam Institute for Climate Impact Research (PIK), builds on years of research showing there are nine systems and processes -- the planetary boundaries -- that contribute to the stability of the planet's life-support functions. Thresholds beyond which they can no longer properly function have already been breached in six. Climate change, the introduction of novel entities, change in biosphere integrity and modification of biogeochemical flows are judged to be in high-risk zones, while planetary boundaries are also transgressed in land system change and freshwater change but to a lesser extent. All have worsened, according to the data. Stratospheric ozone depletion has remained stable, however, and there has been a slight improvement in atmospheric aerosol loading, the research says. At a briefing outlining the findings, Levke Caesar, a climate physicist at PIK and co-author of the report, said there were two reasons the levels of ocean acidification were concerning.

Microsoft unveiled detailed security reforms Monday, five months after CEO Satya Nadella pledged to prioritize cybersecurity following major breaches. The 25-page Secure Future Initiative report [PDF] outlines technical and governance changes addressing criticisms in an April 2024 Cyber Safety Review Board report that deemed Microsoft's security culture "inadequate." Microsoft said it implemented significant security upgrades to its Entra ID and Microsoft Account systems, introducing Azure-managed hardware security modules for access token signing keys. The company has also purged 5.75 million inactive tenants to minimize potential attack vectors and adopted a new testing system with secure defaults to prevent legacy-related security issues. Concurrently, Microsoft has enhanced its network tracking capabilities, now monitoring over 99 percent of its physical network through a centralized inventory system, which aids in firmware compliance and logging. Internal security measures have been tightened, with engineering teams facing stricter access controls. Personal access tokens are now limited to seven days, SSH access has been disabled for internal engineering repositories, and access to critical engineering systems has been restricted to fewer groups. Additionally, Microsoft has extended its audit log retention period to a minimum of two years, bolstering its ability to investigate and respond to potential security incidents.

Marc Benioff said Microsoft's Copilot AI hasn't lived up to the hype. The Salesforce CEO said on the company's second-quarter earnings call that its own AI is nothing like Copilot, which he said was unimpressive. From a report: "So many customers are so disappointed in what they bought from Microsoft Copilot because they're not getting the accuracy and the response that they want," Benioff said. "Microsoft has disappointed so many customers with AI." Microsoft Copilot integrates OpenAI's ChatGPT tech into the company's existing suite of business software like Word, Excel, and PowerPoint that comes with Microsoft 365. Launched last year, Copilot is meant to help companies boost productivity by responding to employee prompts and helping them with daily tasks like scheduling meetings, writing up product announcements, and creating presentations. In response to Benioff's comments, Jared Spataro, Microsoft's corporate vice president for AI at work, said in a statement to Fortune that the company was "hearing something quite different" from its customers.

Messaging app Telegram will provide users' IP addresses and phone numbers to relevant authorities in response to valid legal requests, according to Chief Executive Officer Pavel Durov. From a report: The platform changed its terms of service to deter criminals from abusing it, Durov said in a post on Telegram Monday. The move comes less than a month after his arrest in France, where he faces charges of alleged complicity in the spread of child sexual abuse materials. The move represents a marked difference from Telegram's approach to government requests for data and its reputation for lax moderation. The United Arab Emirates-based platform has been notoriously non-responsive to takedown requests from governments around the world, and often ignored requests for information about suspected criminals.

How Sonos Botched an App and Infuriated Its Customers

Par : msmash
23 septembre 2024 à 15:21
Sonos launched a disastrous app update in May, prompting CEO Patrick Spence to commission an internal investigation led by chief counsel Eddie Lazarus. The software release, plagued with missing features and bugs, has sparked widespread customer outrage and led to a $200 million revenue shortfall. Sonos shares have plummeted 25% this year. Lazarus interviewed about two dozen employees and reviewed meeting recordings before presenting his findings to the board in late July. Bloomberg: What has happened to Sonos is at its heart a cautionary tale of company leadership ignoring the perils of "technical debt," the term used by software engineers to describe the compounding threat of outdated code and infrastructure on security, usability and stability. For two decades, Sonos had allowed its tech debt to pile high. When it undertook in earnest its effort to revamp its app in mid-2022, the company knew it was sitting on infrastructure and code written in languages that were pretty much obsolete. The Sonos app had been adapted and spliced and tinkered with so often, the vast majority of work being performed for the new app was less about introducing new functionality than sorting out the existing mess. The company could have tackled its tech debt sooner but appears to have lacked a crucial element: urgency. It finally came in the form of the Sonos Ace headphones, the first product in the Sonos range to be fully mobile rather than using home or office Wi-Fi. The app needed to be rebuilt, as did the cloud computing setup underpinning it. Ace is a critical product for Sonos. Now that Sonos' pandemic sales boom has subsided, Wall Street has started to question where revenue growth will come from. Sonos Ace is a big part of the answer. Despite the company's lofty and well-earned reputation, Sonos' share of the $100 billion audio market is only around 2% because it has not gone toe-to-toe in the headphones category with Apple, Sennheiser, Bose and the rest.

US Proposes Ban on Smart Cars With Chinese and Russian Tech

23 septembre 2024 à 14:00
The US Commerce Department on Monday will propose a ban on the sale or import of smart vehicles that use specific Chinese or Russian technology because of national security concerns, according to US officials. From a report: A US government investigation that began in February found a range of national security risks from embedded software and hardware from China and Russia in US vehicles, including the possibility of remote sabotage by hacking and the collection of personal data on drivers, Secretary of Commerce Gina Raimondo told reporters Sunday in a conference call. "In extreme situations, a foreign adversary could shut down or take control of all their vehicles operating in the United States, all at the same time, causing crashes (or) blocking roads," she said. The rule would not apply to cars already on the road in the US that already have Chinese software installed, a senior administration official told CNN. The software ban would take effect for vehicles for "model year" 2027 and the hardware ban for "model year" 2030, according to the Commerce Department. The proposed regulatory action is part of a much broader struggle between the United States and China, the world's two biggest economies, to secure the supply chains of the key computing technology of the future, from semiconductors to AI software. China, in particular, has invested heavily in the connected car market, and inroads made by Chinese manufacturers in Europe have worried US officials.

Tech Giants Push To Dilute Europe's AI Act

The world's biggest technology companies have embarked on a final push to persuade the European Union to take a light-touch approach to regulating AI as they seek to fend off the risk of billions of dollars in fines. From a report: EU lawmakers in May agreed the AI Act, the world's first comprehensive set of rules governing the technology, following months of intense negotiations between different political groups. But until the law's accompanying codes of practice have been finalised, it remains unclear how strictly rules around "general purpose" AI (GPAI) systems, such as OpenAI's ChatGPT will be enforced and how many copyright lawsuits and multi-billion dollar fines companies may face. The EU has invited companies, academics, and others to help draft the code of practice, receiving nearly 1,000 applications, an unusually high number according to a source familiar with the matter who requested anonymity because they were not authorised to speak publicly. The AI code of practice will not be legally binding when it takes effect late next year, but it will provide firms with a checklist they can use to demonstrate their compliance. A company claiming to follow the law while ignoring the code could face a legal challenge.

American Battery Technology and lithium-producer Albemarle are among 25 companies getting more than $3 billion in funding from the Biden administration to boost domestic production of advanced batteries and components. From a report: The funding -- part of a broader White House goal of creating an American battery supply chain -- is going to projects that are building, expanding or retrofitting facilities to process critical minerals, build components and batteries and recycle materials, the Energy Department said Friday. American Battery Technology received $150 million to build a commercial-scale lithium-ion battery recycling facility in South Carolina. Albemarle is getting $67 million to retrofit a facility to manufacture commercial anode material for next-generation lithium-ion batteries around Charlotte, North Carolina. Other projects included $50 million for Cabot and $225 million for SWA Lithium, a joint venture of Standard Lithium and Equinor. Batteries -- which are used for electric vehicles as well as storing renewable energy for use on the electric grid -- are considered critical to reaching the administration's goal of net-zero emissions by 2050 and for boosting electric vehicles to half of all new light-duty vehicle sales by 2030.

Antarctic 'Doomsday Glacier' Melting Faster, Scientists Warn

Par : msmash
21 septembre 2024 à 07:31
A massive Antarctic glacier, dubbed the "Doomsday Glacier," is melting at an accelerating rate and could be approaching irreversible collapse, international researchers are reporting. The Thwaites Glacier, holding enough ice to raise global sea levels by over two feet, has seen rapid retreat in the past 30 years. Scientists from the International Thwaites Glacier Collaboration used ice-breaking ships and underwater robots to study the glacier up close since 2018. Their findings reveal warm ocean water funneling through deep cracks in the ice, causing unexpected melting patterns. While computer modeling suggests catastrophic cliff collapse is less likely than feared, researchers project Thwaites and the Antarctic Ice Sheet could disintegrate within 200 years. This collapse could ultimately lead to 10 feet of sea level rise, devastating coastal communities worldwide.
