The Ingenuity Mars Helicopter Just Sent Its Last Message Home

Sun, 2024-04-21 22:25
Two months ago the team behind NASA's Ingenuity Helicopter released a video reflecting on its historic explorations of Mars, flying 10.5 miles (17.0 kilometers) in 72 different flights over three years. It was the team's way of saying goodbye, according to NASA's video. And this week, LiveScience reports, Ingenuity answered back: On April 16, Ingenuity beamed back its final signal to Earth, which included the remaining data it had stored in its memory bank and information about its final flight. Ingenuity mission scientists gathered in a control room at NASA's Jet Propulsion Laboratory (JPL) in California to celebrate and analyze the helicopter's final message, which was received via NASA's Deep Space Network, made up of ground stations located across the globe. In addition to the remaining data files, Ingenuity sent the team a goodbye message including the names of all the people who worked on the mission. This special message had been sent to Perseverance the day before and relayed to Ingenuity to send home. The helicopter, which still has power, will now spend the rest of its days collecting data from its final landing spot in Valinor Hills, named after a location in J.R.R. Tolkien's "The Lord of the Rings" books. The chopper will wake up daily to test its equipment, collect a temperature reading and take a single photo of its surroundings. It will continue to do this until it loses power or fills up its remaining memory space, which could take 20 years. Such a long-term dataset could not only benefit future designs for Martian vehicles but also "provide a long-term perspective on Martian weather patterns and dust movement," researchers wrote in the statement. However, the data will be kept on board the helicopter and not beamed back to Earth, so it must be retrieved by future Martian vehicles or astronauts. "Whenever humanity revisits Valinor Hills — either with a rover, a new aircraft, or future astronauts — Ingenuity will be waiting with her last gift of data," Teddy Tzanetos, an Ingenuity scientist at JPL, said in the statement. Thursday NASA's Jet Propulsion Laboratory released another new video tracing the entire route of Ingenuity's expedition over the surface of Mars. "Ingenuity's success could pave the way for more extensive aerial exploration of Mars down the road," adds Spacae.com: Mission team members are already working on designs for larger, more capable rotorcraft that could collect a variety of science data on the Red Planet, for example. And Mars isn't the only drone target: In 2028, NASA plans to launch Dragonfly, a $3.3 billion mission to Saturn's huge moon Titan, which hosts lakes, seas and rivers of liquid hydrocarbons on its frigid surface. The 1,000-pound (450 kg) Dragonfly will hop from spot to spot on Titan, characterizing the moon's various environments and assessing its habitability.

GPT-4 Can Exploit Real Vulnerabilities By Reading Security Advisories

Sun, 2024-04-21 21:05
Long-time Slashdot reader tippen shared this report from the Register: AI agents, which combine large language models with automation software, can successfully exploit real world security vulnerabilities by reading security advisories, academics have claimed. In a newly released paper, four University of Illinois Urbana-Champaign (UIUC) computer scientists — Richard Fang, Rohan Bindu, Akul Gupta, and Daniel Kang — report that OpenAI's GPT-4 large language model (LLM) can autonomously exploit vulnerabilities in real-world systems if given a CVE advisory describing the flaw. "To show this, we collected a dataset of 15 one-day vulnerabilities that include ones categorized as critical severity in the CVE description," the US-based authors explain in their paper. "When given the CVE description, GPT-4 is capable of exploiting 87 percent of these vulnerabilities compared to 0 percent for every other model we test (GPT-3.5, open-source LLMs) and open-source vulnerability scanners (ZAP and Metasploit)...." The researchers' work builds upon prior findings that LLMs can be used to automate attacks on websites in a sandboxed environment. GPT-4, said Daniel Kang, assistant professor at UIUC, in an email to The Register, "can actually autonomously carry out the steps to perform certain exploits that open-source vulnerability scanners cannot find (at the time of writing)." The researchers wrote that "Our vulnerabilities span website vulnerabilities, container vulnerabilities, and vulnerable Python packages. Over half are categorized as 'high' or 'critical' severity by the CVE description...." "Kang and his colleagues computed the cost to conduct a successful LLM agent attack and came up with a figure of $8.80 per exploit"

Is Rivos Building an RISC-V AI Chip?

Sun, 2024-04-21 20:05
Remember when Apple filed a lawsuit against chip startup Rivos (saying that in one year Rivos hired more than 40 former Apple employees to work on competing system-on-a-chip technology)? Apple settled that suit in February. And now Tuesday Rivos announced that it raised $250 million, according to Reuters, "in a funding round that will enable it to manufacture its first server chip geared for artificial intelligence," combining a CPU with an AI-accelerating component optimized for LLMs and data analytics. Nvidia gobbled up more than 80% market share of AI chips in 2023. But a host of startups and chip giants have started to launch competing products, such as Intel's Gaudi 3 and Meta's inference chip — both unveiled last week. Rivos is tight-lipped about the specifics of the product, but has disclosed that its plans include designing chips based on the RISC-V architecture, which is an open source alternative to the architectures made by Arm, Intel, and Advanced Micro Devices.. [U]sing the open source alternative means Rivos does not have to pay a license fee to Arm. "RISC-V doesn't have a (large) software ecosystem, so I decided to form a company and then build software-defined hardware — just like what CUDA did with Nvidia," said Lip-Bu Tan, founding managing partner at Walden Catalyst, one of Rivos' investors. Meanwhile, there's a rumor that Allen Wu, former chief executive of Arm China, has founded a new company that will develop chips based on RISC-V. Tom's Hardware writes: Under the leadership of the controversial Allen Wu, Zhongzhi Chip is reportedly attracting a notable influx of talent, including numerous former employees of Arm, indicating the new company's serious ambitions in the chip sector... [T]he company's operational focus remains partially unclear, with speculation around whether it will primarily engage in its own R&D initiatives or represent Tenstorrent in China as its agent... which develops HPC CPUs and AI processors based on the RISC-V ISA... Based on the source report, Zhongzhi Chip is leveraging its connections and forming alliances with several other leading global RISC-V chip developers.

Lying to Investors? Co-Founder of Startup 'HeadSpin' Gets 18-Month Prison Sentence for Fraud

Sun, 2024-04-21 19:05
The co-founder of Silicon Valley-based software testing startup HeadSpin was sentenced Friday to 18 months in prison and a $1 million fine, reports SFGate — for defrauding investors. Lachwani pleaded guilty to two counts of wire fraud and a count of securities fraud in April 2023, after federal prosecutors accused him of, for years, lying to investors about HeadSpin's finances to raise more money. HeadSpin, founded in 2015, grew to a $1.1 billion valuation by 2020 with over $115 million in funding from investors including Google Ventures and Iconiq Capital... He had personally altered invoices, lied to the company accountant and sent slide decks with fraudulent information to investors, [according to the government's 2021 criminal complaint]... Breyer, per the New York Times, rejected Lachwani's lawyer's argument that because HeadSpin investors didn't end up losing money, he should receive a light sentence. The judge, who often oversees tech industry cases, reportedly said: "If you win, there are no serious consequences — that simply can't be the law." Still, the sentencing was far lighter than it could have been. The government's prosecuting attorneys had asked for a five-year prison term. The New York Times reported in December that HeadSpin's financial statements had "often arrived months late, if at all, investors said in legal declarations," while the company's financial department "consisted of one external accountant who worked mostly from home using QuickBooks." And the comnpany also had no human resources department or organizational chart... After Manish Lachwani founded the Silicon Valley software start-up HeadSpin in 2015, he inflated the company's revenue numbers by nearly fourfold and falsely claimed that firms including Apple and American Express were customers. He showed a profit where there were losses. He used HeadSpin's cash to make risky trades on tech stocks. And he created fake invoices to cover it all up. What was especially breathtaking was how easily Mr. Lachwani, now 48, pulled all that off... [HeadSpin] had no chief financial officer, had no human resources department and was never audited. Mr. Lachwani used that lack of oversight to paint a rosier picture of HeadSpin's growth. Even though its main investors knew the start-up's financials were not accurate, according to Mr. Lachwani's lawyers, they chose to invest anyway, eventually propelling HeadSpin to a $1.1 billion valuation in 2020. When the investors pushed Mr. Lachwani to add a chief financial officer and share more details about the company's finances, he simply brushed them off. These details emerged this month in filings in U.S. District Court for the Northern District of California after Mr. Lachwani had pleaded guilty to three counts of fraud in April... The absence of controls at HeadSpin is part of an increasingly noticeable pattern at Silicon Valley start-ups that have run into trouble. Over the past decade, investors in tech start-ups were so eager to back hot companies that many often overlooked reckless behavior and gave up key controls like board seats, all in the service of fast growth and disruption. Then when founders took the ethos of "fake it till you make it" too far, their investors were often unaware or helpless... Now, amid a start-up shakeout, more frauds have started coming to light. The founder of the college aid company Frank has been charged, the internet connectivity start-up Cloudbrink has been sued, and the social media app IRL has been investigated and sued. Last month, Mike Rothenberg, a Silicon Valley investor, was found guilty on 21 counts of fraud and money laundering. On Monday, Trevor Milton, founder of the electric vehicle company Nikola, was sentenced to four years in prison for lying about Nikola's technological capabilities. The Times points out that similarly, FTX only had a three-person board "with barely any influence over the company, tracked its finances on QuickBooks and used a small, little-known accounting firm." And that Theranos had no financial audits for six years.

Should Automakers Feel Threatened by China's Exports of Electric Cars?

Sun, 2024-04-21 17:34
The Los Angeles Times reports that the U.S.-China rivalry "has a new flashpoint in the battle for technology supremacy: electric cars." "So far, the U.S. is losing." Last year, China became the world's foremost auto exporter, according to the China Passenger Car Assn., surpassing Japan with more than 5 million sales overseas. New energy vehicles accounted for about 25% of those exports, and more than half of those were created by Chinese brands, a shift from the traditional assembly role China has played for foreign automakers. "The big growth has happened in the last three years," said Stephen Dyer, head of the Asia automotive and industrials unit at AlixPartners, a consulting firm. "With Chinese automakers making inroads for most of the market share, that's a huge challenge for foreign automakers." China's rapid expansion domestically and abroad has added fuel to a series of clashes between the U.S. and China over trade and advanced technology, as competition intensifies between the two superpowers... One area in which Chinese automakers handily beat Western competitors is on price, thanks to government subsidies that supported the industry's initial rise as well as cheap access to critical minerals and components such as lithium-ion batteries, which account for about a third of the overall cost of production... In March, BYD cut the price of its cheapest EV model in China to less than $10,000. According to Kelley Blue Book, the average EV retail price is $55,343 in the U.S., compared with $48,247 across all vehicles... Though 27.5% tariffs have in effect locked Chinese EVs out of the U.S. market, the fear that the cheaper models could eventually undermine American automakers has started to spread. The Alliance of American Manufacturing warned in a February report that allowing Chinese EVs into the country would be an "extinction-level event" for the U.S. auto industry. The group also cited the risks of Chinese auto companies building facilities across the border in Mexico that could circumvent tariffs.... "When the global market is flooded by artificially cheap Chinese products, the viability of American and other foreign firms is put into question," [said America's Treasury Secretary in April]. The European Union has opened an investigation into government subsidies utilized by China's EV industry and whether such support violates international trade laws.

LXQt 2.0 Released: Lightweight Desktop is Almost Wayland Compatible

Sun, 2024-04-21 16:34
This week saw the release of the LXQt 2.0 desktop environment, reports 9to5Linux. And besides bringing Qt 6 support (and a new default application menu), it also brings support for the Wayland display protocol to more components: The LXQt development is confident that the next major release, LXQt 2.1, will be fully Wayland compatible. The components that need to be ported to Wayland include ScreenGrab, LXQt Global Shortcuts, LXQt Panel's task-bar and keyboard indicator, some input settings, and settings of monitor, power button, and screen locker. "Wayland will be the main target for LXQt 2.1.0, as Qt6 was for LXQt 2.0.0" said the devs. "Most Wayland compositors have tools that can be used instead of them, such that an LXQt-Wayland session is already possible for advanced users." The lightweight Linux distro Lubuntu uses LXQtplace in place of GNOME — and Lubuntu 24.04 LTS will include an optional Wayland session alongside its default Xorg one, according to 9to5Linux: I said it before and I'll say it again, 2024 is the year of the Wayland desktop... The Lubuntu team plans to support the Xorg session until 2026 to aid users with older GPUs... However, the tables will be turned next year with the Lubuntu 24.10 release, which will be shipping with Wayland by default.

How a Renewable Energy-Powered Bitcoin Startup Helps Electrify Rural Africa

Sun, 2024-04-21 15:34
CNBC visited a small group of bitcoin miners who "set up shop at the site of an extinct volcano" near Kenya's Hell's Gate National Park. Their mine "consists of a single 500-kilowatt mobile container that, from the outside, looks like a small residential trailer." But what's more interesting is it's operated by a startup called Gridless. (According to its web site Gridless "designs, builds, and operates bitcoin mining sites alongside small-scale renewable energy producers in rural Africa where excess energy is not utilized...") Backed by Jack Dorsey's Block, Gridless electrifies its machines with a mix of solar power and the stranded, wasted energy from a nearby geothermal site. It's one of six mines run by the company in Kenya, Malawi and Zambia, powered by a mix of renewable inputs and working toward a broader mission of securing and decentralizing the bitcoin network... In early 2022, [the three Gridless co-founders] began brainstorming creative solutions for the divide between power generation and capacity, and the lack of access to electricity in Africa. They landed on the idea of bitcoin mining, which could potentially solve a big problem for renewable energy developers by taking their stranded power and spreading it to other parts of the continent. In Africa, 43% of the population, or roughly 600 million people, lack access to electricity.... Africa is home to an estimated 10 terawatts of solar capacity, 350 gigawatts of hydro and another 110 gigawatts of wind. Some of this renewable energy is being harnessed already, but a lot isn't because building the specialized infrastructure to capture it is expensive. Even with 60% of the best solar resources globally, Africa only has 1% of installed solar PV capacity. Enter bitcoin miners. Bitcoin gets a bad rap for the amount of energy it consumes, but it can also help unlock these trapped renewable sources of power. Miners are essentially energy buyers, and co-locating with renewables creates a financial incentive to bolster production. "As often happens, you'll have an overage of power during the day or even at night, and there's nobody to soak that power up," said Hersman. He said his company's 50-kilowatt mining container can "take up whatever is extra throughout the day...." Demand from bitcoin miners on these semi-stranded assets is making renewables in Africa economically viable. The power supplier benefits from selling energy that previously had been discarded, while the energy plants will sometimes lower costs for the customer. At one of the Gridless pilot sites in Kenya, the hydro plant dropped the price of power from 35 cents per kilowatt hour to 25 cents per kWh. The buildout of capacity is also electrifying households. Gridless says its sites have powered 1,200 houses in Zambia, 1,800 in Malawi and 5,000 in Kenya. The company's mines also have delivered power for containerized cold storage for local farmers, battery charging stations for electric motorcycles and public WiFi points.

EU: Meta Cannot Rely On 'Pay Or Okay'

Sun, 2024-04-21 14:34
The EU's European Data Protection Board oversees its privacy-protecting GDPR policies. Earlier this week, TechCrunch reported that nearly two dozen civil society groups and nonprofits wrote the Board an open letter "urging it not to endorse a strategy used by Meta that they say is intended to bypass the EU's privacy protections for commercial gain." Meta's strategy is sometimes called "Pay or Okay," writes long-time Slashdot reader AmiMoJo : Meta offers users a choice: "consent" to tracking, or pay over €250/year to use its sites without invasive monetization of personal data. Meta prefers the phrase "subsccription for no ads," and told TechCrunch it makes them compliant with EU laws: A raft of complaints have been filed against Meta's implementation of the pay-or-consent tactic since it launched the "no ads" subscription offer last fall. Additionally, in a notable step last month, the European Union opened a formal investigation into Meta's tactic, seeking to find whether it breaches obligations that apply to Facebook and Instagram under the competition-focused Digital Markets Act. That probe remains ongoing. The letter to the Board called for "robust protections that prioritize data subjects' agency and control over their information." And Wednesday the board issued its first decision: "[I]n most cases, it will not be possible for [social media services] to comply with the requirements for valid consent, if they confront users only with a choice between consenting to processing of personal data for behavioural advertising purposes and paying a fee." The EDPB considers that offering only a paid alternative to services which involve the processing of personal data for behavioural advertising purposes should not be the default way forward for controllers. When developing alternatives, large online platforms should consider providing individuals with an 'equivalent alternative' that does not entail the payment of a fee. If controllers do opt to charge a fee for access to the 'equivalent alternative', they should give significant consideration to offering an additional alternative. This free alternative should be without behavioural advertising, e.g. with a form of advertising involving the processing of less or no personal data. EDPB Chair, Anu Talus added: "Controllers should take care at all times to avoid transforming the fundamental right to data protection into a feature that individuals have to pay to enjoy."

Ziplines Drones Complete Their 1 Millionth Delivery, Flying Over 70 Million Miles

Sun, 2024-04-21 11:34
San Francisco-based drone-delivery service Zipline "said Friday that it hit its 1 millionth delivery to customers," reports CNBC, "and that it's eyeing restaurant partnerships in its next phase of growth." Zipline's clients already include more than 4,700 hospitals, according to the article, as well as major brands like Walmart. A Panera executive even told CNBC they hope to test Zipline deliveries in Seattle next year, expecting they won't cost the company any more than third-party delivery services: The company said its zero-emission drones have now flown more than 70 million autonomous commercial miles across four continents and delivered more than 10 million products. The milestone 1 millionth delivery carried two bags of IV fluid from a Zipline distribution center in Ghana to a local health facility... Zipline CEO Keller Rinaudo Cliffton told CNBC that 70% of the company's deliveries have happened in the past two years and, in the future, the goal is to do 1 million deliveries a day... "We need to start using vehicles that are light, fast, autonomous and zero-emission," Cliffton said. "Delivering in this way is 10 times as fast, it's less expensive ... and relative to the traditional delivery apps that most restaurants will be working with, we triple the service radius, which means you actually [get] 10 times the number of customers who are reachable via instant delivery."

Some Astronomers Will Re-Examine a 102-Year-Old Theory About the Universe's Expansion

Sun, 2024-04-21 07:34
Several "high-profile astronomers" will meet at London's Royal Society (the UK's national academy of sciences), "to question some of the most fundamental aspects of our understanding of the universe.reports Futurism: As The Guardian reports, the luminaries of cosmology will be re-examining some basic assumptions about the universe — right down to the over-a-century-old theory that it's expanding at a constant rate. "We are, in cosmology, using a model that was first formulated in 1922," coorganizer and Oxford cosmologist Subir Sarkar told the newspaper, in an apparent reference to the year Russian astronomer Alexander Friedmann outlined the possibility of cosmic expansion based on Einstein's general theory of relativity. "We have great data, but the theoretical basis is past its sell-by date," he added. "More and more people are saying the same thing and these are respected astronomers." A number of researchers have found evidence that the universe may be expanding more quickly in some areas compared to others, raising the tantalizing possibility that megastructures could be influencing the universe's growth in significant ways. Sarkar and his colleagues, for instance, are suggesting that the universe is "lopsided" after studying over a million quasars, which are the active nuclei of galaxies where gas and dust are being gobbled up by a supermassive black hole. The article notes that another theory is that the so-called cosmological constant that's been used for decades "actually varies across space."

Insufficient Redundancy? Light-Pole Installation Cut Fiber Line, Triggered Three-State 911 Outage

Sun, 2024-04-21 03:34
"Workers installing a light pole in Missouri cut into a fiber line," reports the Associated Press, knocking out 911 phone service "for emergency agencies in Nebraska, Nevada and South Dakota, an official with the company that operates the line said Thursday." In Kansas City, Missouri, workers installing a light pole for another company Wednesday cut into a Lumen Technologies fiber line, Lumen global issues director Mark Molzen said in an email to The Associated Press. Service was restored within 2 1/2 hours, he said. There were no reports of 911 outages in Kansas City... The Dundy County Sheriff's Office in Nebraska warned in a social media post Wednesday night that 911 callers would receive a busy signal and urged people to instead call the administrative phone line. About three hours later, officials said mobile and landline 911 services had been restored. In Douglas County, home to Omaha and more than a quarter of Nebraska's residents, officials first learned there was a problem when calls from certain cellphone companies showed up in a system that maps calls but didn't go through over the phone. Operators started calling back anyone whose call didn't go through, and officials reached out to Lumen, which confirmed the outage. Service was restored by 4 a.m. Kyle Kramer, the technical manager for Douglas County's 911 Center, said the outage highlights the potential problems of having so many calls go over the same network. "As things become more interconnected in our modern world, whether you're on a wireless device or a landline now, those are no longer going over the traditional old copper phone wires that may have different paths in different areas," Kramer said. "Large networks usually have some aggregation point, and those aggregation points can be a high risk." Kramer said this incident and the two previous 911 outages he has seen in the past year in Omaha make him concerned that communications companies aren't building enough redundancy into their networks. South Dakota officials called the state-wide outage "unprecedented," with their Department of Public Safety reporting the outage lasted two hours (though texting to 911 still worked in most locations — and of course, people could still call local emergency services using their non-emergency lines.) America's FCC has already begun an investigation. The article notes that "The outages, ironically, occurred in the midst of National Public Safety Telecommunicators Week."

Could the Earth's Record Hot Streak Signal a New Climate Era?

Sat, 2024-04-20 22:34
South America's Amazon River has reached its lowest level since measurements began, according to the Washington Post, while temperatures "hovered above 110 degrees Fahrenheit" for nearly a week as April began in the capital of Mali. "Nights offered little relief, with temperatures often staying above 90 degrees..." "An overtaxed electrical grid sputtered and shut down," they add, and "dehydration and heat stroke became epidemic... At the city's main hospital, doctors recorded a month's worth of deaths in just four days. Local cemeteries were overwhelmed." The historic heat wave that besieged Mali and other parts of West Africa this month — which scientists say would have been "virtually impossible" in a world without human-caused climate change — is just the latest manifestation of a sudden and worrying surge in global temperatures. Fueled by decades of uncontrolled fossil fuel burning and an El Niño climate pattern that emerged last June, the planet this year breached a feared warming threshold of 1.5 degrees Celsius above preindustrial levels. Nearly 19,000 weather stations have notched record high temperatures since January 1. Each of the last ten months has been the hottest of its kind. The scale and intensity of this hot streak is extraordinary even considering the unprecedented amount of greenhouse gases in the atmosphere, researchers say. Scientists are still struggling to explain how the planet could have exceeded previous temperature records by as much as half a degree Celsius (0.9 degrees Fahrenheit) last fall. What happens in the next few months, said Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, could indicate whether Earth's climate has undergone a fundamental shift — a quantum leap in warming that is confounding climate models and stoking ever more dangerous weather extremes. But even if the world returns to a more predictable warming trajectory, it will only be a temporary reprieve from the conditions that humanity must soon confront, Schmidt said. "Global warming continues apace." Will this summer's La Niña cool things off? More atmospheric research is underway, and "Schmidt says it's too soon to know how worried the world should be," according to the article. But he does raise this possibility. "What if the statistical connections that we are basing our predictions on are no longer valid?" "It's niggling at the back of my brain that it could be that the past is no longer a guide to the future."

US Passes Bill Reauthorizing 'FISA' Surveillance for Two More Years

Sat, 2024-04-20 21:34
Late Friday night the U.S. Senate "reauthorized the Foreign Intelligence Surveillance Act, a key. U.S. surveillance authority," reports Axios, "shortly after it expired in the early hours Saturday morning." The reauthorization came despite bipartisan concerns about Section 702, which allows the government to collect communications from non-U.S. citizens overseas without a warrant. The legislation passed the Senate 60 to 34, with 17 Democrats, Sen. Bernie Sanders (I-Vt.) and 16 Republicans voting "nay." It extends the controversial Section 702 for two more years. The bill had already passed last week in the U.S. House of Representatives, explains CNN: Under FISA's Section 702, the government hoovers up massive amounts of internet and cell phone data on foreign targets. Hundreds of thousands of Americans' information is incidentally collected during that process and then accessed each year without a warrant — down from millions of such queries the US government ran in past years. Critics refer to these queries as "backdoor" searches... According to one assessment, it forms the basis of most of the intelligence the president views each morning and it has helped the U.S. keep tabs on Russia's intentions in Ukraine, identify foreign efforts to access US infrastructure, uncover foreign terror networks and thwart terror attacks in the U.S. An interesting detail from The Verge: Sens. Ron Wyden (D-OR) and Josh Hawley (R-MO) introduced an amendment that would have struck language in the House bill that expanded the definition of "electronic communications service provider." Under the House's new provision, anyone "who has access to equipment that is being or may be used to transmit or store wire or electronic communications." The expansion, Wyden has claimed, would force "ordinary Americans and small businesses to conduct secret, warrantless spying." The Wyden-Hawley amendment failed 34-58, meaning that the next iteration of the FISA surveillance program will be more expansive than before. Saturday morning the U.S. House of Representatives passed a bill banning TikTok if its Chinese owner doesn't sell the app.

JWST Gets an IMAX Documentary: 'Deep Sky'

Sat, 2024-04-20 20:34
A large-screen IMAX documentary about the James Webb Space Telescope "has just opened in 300 theaters across North America," write an anonymous Slashdot reader, noting that it's playing for one week only. "And it gets a rave review in Forbes." Imagine venturing to the beginning of time and space, exploring cosmic landscapes so vast and beautiful that they've remained unseen by human eyes until now. This is the promise of "Deep Sky," an extraordinary IMAX presentation that brings the universe's awe-inspiring mysteries closer than ever before. Directed by the Oscar®-nominated filmmaker Nathaniel Kahn and narrated by the equally acclaimed actress Michelle Williams, "Deep Sky" is a monumental journey through the cosmos, powered by the groundbreaking images captured by NASA's Webb Telescope... "Deep Sky" is more than a documentary about a space telescope; it's an immersive experience that invites audiences to see the universe as never before. Through the power of IMAX, viewers are transported across 13 billion years of cosmic history, to the very edges of the observable universe. Here, in stunning clarity, we witness the birth of stars, the formation of galaxies, and the eerie beauty of exoplanets — planets that orbit stars beyond our own Sun. These images, beamed back to Earth by JWST, reveal the universe's vast beauty on a scale that seems only the giant IMAX screen can begin to convey... What makes "Deep Sky" particularly captivating is its ability to render the incomprehensible beauty and scale of the universe accessible. The IMAX® experience, known for its breathtaking visuals and sound, serves as the perfect medium to convey the majesty of the cosmos. The review says the film celebrates the achieve of thousands of people working across decades, "aiming to answer some of humanity's oldest questions: Where did we come from? How did the universe begin? Are we alone in the vastness of space?" The reviewer also spoke to JWST telescope scientist Matt Mountain — in another article applauding the film for "encapsulating the grandeur of space exploration on the IMAX canvas." In "Deep Sky," viewers are taken on a journey from the telescope's construction to its deployment and early operational phases. The documentary highlights the international collaboration and engineering marvels behind the JWST, featuring insights from key scientists and engineers who brought the telescope to life. The film aims to rekindle a sense of wonder about the universe and our place within it, emphasizing the human desire to explore and understand the cosmos.

The Legendary Zilog Z80 CPU Is Being Discontinued After Nearly 50 Years

Sat, 2024-04-20 19:34
Long-time Slashdot reader AmiMoJo shares an article from TechSpot: Zilog is retiring the Z80 after 48 years on the market. Originally developed as a project stemming from the Intel 8080, it eventually rose to become one of the most popular and widely used 8-bit CPUs in both gaming and general computing devices. The iconic IC device, developed by Federico Faggin, will soon be phased out, and interested parties only have a few months left to place their orders before Zilog's manufacturing partner ends support for the technology... Federico Faggin, an Intel engineer, founded Zilog in 1974 after his work on the Intel 4004, the first 4-bit CPU. The Zilog Z80 was then released in July 1976, conceived as a software-compatible 'extension' and enhancement of the Intel 8080 processor. Back in 1999 Slashdot was calling Zilog's updated eZ80 "one of the fastest 8-bit CPUs available today, executing code 4 times faster than a standard Z80 operating at the same clock speed." Another headline, from 2001: Zilog To File For Chapter 11...

Sell or Be Banned: Anti-TikTok Bill Passed by US Representatives

Sat, 2024-04-20 18:34
The U.S. House of Representatives just passed its long-delayed Ukraine aid bill. But along with it they also approved a bill banning TikTok "if its Chinese owner does not sell the video app," according to NPR: While lawmakers in the House advanced a similar bill last month, this effort is different for two reasons: It is attached to a sweeping foreign aid bill providing support for Ukraine and Israel. And it addresses concerns from some members of the Senate by extending the deadline for TikTok to find a buyer. President Biden supports the effort. That means TikTok being forced to sell, or face a possible ban, is on the fast-track to becoming law. It would mark the first time ever the U.S. government has passed a law that could shut down an entire social media platform, setting the stage for what is expected to be a protracted legal battle... TikTok says it has built a firewall between its headquarters in Los Angeles and its parent company in Beijing, but some reports indicate U.S. user data does still move between the two. While there has been no evidence made public that Chinese government officials have accessed Americans' information through TikTok, the idea that China has the theoretical ability to weaponize an app used by half of America has been enough to set off an all-out crackdown.

Data Centers Are Turning to an Old Source of Power: Coal

Sat, 2024-04-20 17:34
The Washington Post reports on a new situation in Virginia: There, massive data centers with computers processing nearly 70 percent of global digital traffic are gobbling up electricity at a rate officials overseeing the power grid say is unsustainable unless two things happen: Several hundred miles of new transmission lines must be built, slicing through neighborhoods and farms in Virginia and three neighboring states. And antiquated coal-powered electricity plants that had been scheduled to go offline will need to keep running to fuel the increasing need for more power, undermining clean energy goals... The $5.2 billion effort has fueled a backlash against data centers through the region, prompting officials in Virginia to begin studying the deeper impacts of an industry they've long cultivated for the hundreds of millions of dollars in tax revenue it brings to their communities. Critics say it will force residents near the [West Virginia] coal plants to continue living with toxic pollution, ironically to help a state — Virginia — that has fully embraced clean energy. And utility ratepayers in the affected areas will be forced to pay for the plan in the form of higher bills, those critics say. But PJM Interconnection, the regional grid operator, says the plan is necessary to maintain grid reliability amid a wave of fossil fuel plant closures in recent years, prompted by the nation's transition to cleaner power. Power lines will be built across four states in a $5.2 billion effort that, relying on coal plants that were meant to be shuttered, is designed to keep the electric grid from failing amid spiking energy demands. Cutting through farms and neighborhoods, the plan converges on Northern Virginia, where a growing data center industry will need enough extra energy to power 6 million homes by 2030... There are nearly 300 data centers now in Virginia. With Amazon Web Services pursuing a $35 billion data center expansion in Virginia, rural portions of the state are the industry's newest target for development. The growth means big revenue for the localities that host the football-field-size buildings. Loudoun [County] collects $600 million in annual taxes on the computer equipment inside the buildings, making it easier to fund schools and other services. Prince William [County], the second-largest market, collects $100 million per year. The article adds that one data center "can require 50 times the electricity of a typical office building, according to the U.S. Department of Energy. "Multiple-building data center complexes, which have become the norm, require as much as 14 to 20 times that amount." One small power company even told the grid operator that data centers were already consuming 59% of the power they produce...

Red Hat Upgrades Its Pipeline-Securing (and Verification-Automating) Tools

Sat, 2024-04-20 16:34
SiliconANGLE reports that to help organizations detect vulnerabilities earlier, Red Hat has "announced updates to its Trusted Software Supply Chain that enable organizations to shift security 'left' in the software supply chain." Red Hat announced Trusted Software Supply Chain in May 2023, pitching it as a way to address the rising threat of software supply chain attacks. The service secures software pipelines by verifying software origins, automating security processes and providing a secure catalog of verified open-source software packages. [Thursday's updates] are aimed at advancing the ability for customers to embed security into the software development life cycle, thereby increasing software integrity earlier in the supply chain while also adhering to industry regulations and compliance standards. They start with a new tool called Red Hat Trust Artifact Signer. Based on the open-source Sigstore project [founded at Red Hat and now part of the Open Source Security Foundation], Trust Artifact Signer allows developers to sign and verify software artifacts cryptographically without managing centralized keys, to enhance trust in the software supply chain. The second new release, Red Hat Trusted Profile Analyzer, provides a central source for security documentation such as Software Bill of Materials and Vulnerability Exploitability Exchange. The tool simplifies vulnerability management by enabling proactive identification and minimization of security threats. The final new release, Red Hat Trusted Application Pipeline, combines the capabilities of the Trusted Profile Analyzer and Trusted Artifact Signer with Red Hat's internal developer platform to provide integrated security-focused development templates. The feature aims to standardize and accelerate the adoption of secure development practices within organizations. Specifically, Red Hat's announcement says organizations can use their new Trust Application Pipeline feature "to verify pipeline compliance and provide traceability and auditability in the CI/CD process with an automated chain of trust that validates artifact signatures, and offers provenance and attestations."

Ocean Spray Emits More PFAS Than Industrial Polluters, Study Finds

Sat, 2024-04-20 15:34
An anonymous reader quotes a report from The Guardian: Ocean waves crashing on the world's shores emit more PFAS into the air than the world's industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines. The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water. The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study's lead author. "There is evidence that the ocean can be an important source [of PFAS air emissions]," Cousins said. "It is definitely impacting the coastline." The Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land. The new research looked at levels in the sea spray as waves crash by testing ocean samples between Southampton in the UK and Chile. The chemicals' levels were higher in the northern hemisphere in general because it is more industrialized and there is not much mixing of water across the equator, Cousins said. It is unclear what the findings mean for human exposure. Inhalation of PFAS is an issue, but how much of the chemicals are breathed in, and air concentrations further from the waves, is still unknown.
