AMD NGG Improvements Make It Into Mesa 25.2 Ahead Of Next Week's Code Branching

13 juillet 2025 à 11:19
Last week I wrote about a number of patches coming out of AMD for Next-Gen Geometry "NGG" improvements to the AMD OpenGL and Vulkan drivers for Linux. Some of that code hadn't been merged as of writing but fortunately this week the remainder of the NGG improvements were successfully merged to Mesa Git for this quarter's Mesa 25.2 release...

DC's 'Brighter' Superman Movie Smashes Box Offices Expectations

13 juillet 2025 à 11:34
James Gunn's Superman "appears to be succeeding in rebooting DC Studios and its most iconic comic book franchise," writes The Hollywood Reporter, noting the film is "headed for a possible record domestic box office debut of $115 million to $120 million." Gunn is in a unique position, being both the film's writer-director and the co-head of the Warner Bros.-owned DC, which he co-runs with Peter Safran. Overseas, Superman is launching to $100 million-plus from 78 markets after earning $40 million midweek from its first raft of international markets for an early global total of $96.5 million through Friday. Superman will be the first superhero film to cross $100 million in its North American bow since Marvel Studios and Ryan Reynolds' Deadpool & Wolverine launched to $211 million in summer 2024 ("superhero fatigue" has become part of the Hollywood lexicon). And it's the first DC title to cross $100 million in eight long years since Wonder Woman debuted to $103.3 million in 2017. And if the $225 million tentpole comes in north of $116.6 million, it will beat Zack Snyder's 2013 film Man of Steel ($116.7 million) to rank as the biggest domestic launch ever for a solo Superman pic, not adjusted for inflation. Snyder's mash-up Batman v Superman: Dawn of Justice scored the biggest DC opening of all time when earning $166.6 million over Easter weekend in 2016... Gunn's movie is only the third Hollywood title of 2025 to launch north of $100 million after fellow Warners tentpole A Minecraft Movie, which opened to $162.8 million, and Disney's live-action Lilo & Stitch, which sewed up $146 million in its debut. Crossing the century mark is no small feat for any movie in the post-pandemic era, and particularly for the troubled superhero genre. The pic should enjoy a long run thanks to strong word-of-mouth. Critics and audiences alike are embracing the film. The pic earned an A- CinemaScore from moviegoers, the same grade given to Man of Steel and ahead of Superman Returns' B+. The audience score on Rotten Tomatoes is a stellar 94 percent, while the critics' score is a pleasing 82 percent... Other upcoming DC Studios projects include HBO's Green Lantern series, Lanterns, and a Supergirl movie due out in 2026. Superman's weekend debut at nearly $130 million domestically smashes early estimates of around $90 million (according to a senior media analyst at Comscore). And the film also got a positive reaction from the author of the cultural history Superman: The Unauthorized Biography (writing for NPR): Recent attempts to tell live-action Superman stories have shied away from his bright, hopeful, altruistic nature in favor of making him more cool and relatable (read: dark and brooding). That's not who he is; it never has been. Superman is an ideal. He represents the best we can aspire to be. He's not the hero you relate to, à la Peter Parker/Spider-Man's ongoing struggle to pay his rent and buy Aunt May her damn medicine. He's the hero who inspires you, who shows you the way... It doesn't have to be about slogging through trauma and shame and shadow-selves and endlessly tedious redemption arcs. Sometimes, it's simpler, cleaner, brighter. And also? Not for nothing? More fun.

Astronomers Plan Far Side of the Moon Satellite to Hear Billion-Year-Old Radio Waves

13 juillet 2025 à 07:34
An anonymous reader shared this report from Cosmos magazine about a plan to "pick up those faint signals from billions of years ago." Astronomers are planning to launch a tiny spacecraft to the far side of the Moon to listen out for "ancient whispers" in a quest to uncover the secrets of the early universe. The mission will focus on understanding the 'Cosmic Dawn', a period in the early stages of the universe after the Big Bang but before the first stars and galaxies appeared. One of the difficulties in studying this period of the universe is that silence is essential. With all the electronics and interference in our atmosphere, Earth becomes too loud, making it unsuitable for this kind of research... The proposed mission will utilise the Moon as a giant shield, blocking out the noise from Earth, in order to observe these signals... The mission, known as CosmoCube, is a joint study between the UK's University of Portsmouth, University of Cambridge and Rutherford Appleton Laboratory Space... CosmoCube's radio will operate at low frequencies (10-100MHz), which should hopefully be able to detect extremely faint signals. The team hope to reach lunar orbit before the end of the decade, with a roughly 5-year roadmap planned. The article includes this quote from Professor David Bacon, from the University of Portsmouth and CosmoCube researcher. "It's incredible how far these radio waves have travelled, now arriving with news of the universe's history. "The next step is to go to the quieter side of the Moon to hear that news."

Amelia Earhart's Airplane May Finally Have Been Found

13 juillet 2025 à 03:34
An anonymous reader shared this report from Jalopnik: On July 2, the 88th anniversary of famed aviator Amelia Earhart's disappearance, Purdue University announced an expedition [which will launch in November] to confirm whether or not the wreckage of her plane has been found. Satellite imagery from a decade ago indicated the presence of something that sure looks plane-like under the waters of Nikumaroro Island, an uninhabited spit of land in the middle of the Pacific Ocean that just happens to be near Earhart's intended flightpath... This isn't the first time Earhart investigators have been to Nikumaroro. Human bones were recovered from the island previously, which scientists determined with 99% confidence to belong to the beloved pilot, per the university's student newspaper the Purdue Exponent. The investigators also found some women's beauty products from the 1930s. If that is indeed where Earhart died, it stands to reason that her Lockheed Electra 10E, nicknamed the Flying Laboratory, wouldn't be far away. Since nobody noticed any aircraft wreckage on the island (which isn't very big), it would probably be under the water. Recovering such a legendary airplane will be a multi-stage process spanning years. This expedition, which will embark in November, is only planning to verify what's actually there, not retrieve anything. Recent satellite imagery doesn't show the object anymore, meaning it might have become buried; in fact, it was only ever visible in 2015, right after a cyclone blew threw and shifted a bunch of sand, as NBC News reports. The team will start with non-invasive procedures, such as sonar and magnetometers, before drilling through the silt with a hydroglobe to make physical contact with the object. Lastly, they will use a suction dredge to pull off loose sediment. If they're lucky, that will be sufficient to actually see part of the Lockheed Electra.

EV Sets New Record for Longest Trip on a Single Charge - 749 Miles

13 juillet 2025 à 01:34
Lucid Motors set a Guinness World Record for the longest journey by an electric car on a single charge, covering a distance of 749 miles (about 1,205 km), reports New Atlas. "In doing so, Lucid broke the 1,045-km (649-mile) record previously achieved by the Mercedes-Benz EQS450+ in June 2025 by the Japanese car website www.webcg.net/articles/-/52268webCG." The electric vehicle covered this journey between St. Moritz, Switzerland, and Munich, Germany, traveling through highways, secondary roads, and alpine roads — all without a single halt for charging. Given that the vehicle has a 960-km (596-mile) WLTP range, my guess is that the test team must have made good use of favorable road and weather conditions to make the feat possible. With a net elevation decrease of just over 1,310 m (about 4,300 ft) throughout the drive, the EV most certainly benefited from regenerative braking, a rather useful feature that turns downhill momentum back into battery power. Lucid has yet to release official data like average speed or total drive time, but what is apparent is that this was not a high-speed dash but rather a well-planned route to achieve one impressive result... The Air Grand Touring has two all-wheel drive electric motors with a combined system output of 611 kW (819 horsepower) and 1,200 Nm (885 lb.ft) of torque. Power is provided by an NMC battery, which has a gross energy capacity of 117 kWh (112 kWh usable). Best of all, it can go from 0-60 mph in just three seconds flat... For reference, the almost half-priced BMW i4 and jazzy Porsche Taycan offer less than half the WLTP range of the Lucid Air GT. So, it's not like there's a head-to-head competition out there. Lucid is miles ahead in its class (pun intended!) Starting at US$112,650, the Air Grand Touring is among the most luxurious sedans on the market right now. But as you can see, it comes at a price. Still, knowing that there is technology to conquer range anxiety is comforting. It might take a while, but there's no reason why we can't expect such range figures from reasonably priced EVs in the near future.

'Firefox is Fine. The People Running It are Not'

12 juillet 2025 à 22:34
"Firefox is dead to me," wrote Steven J. Vaughan-Nichols last month for The Register, complaining about everything from layoffs at Mozilla to Firefox's discontinuation of Pocket and Fakespot, its small market share, and some user complaints that the browser might be becoming slower. But a new rebuttal (also published by The Register) argues instead that Mozilla just has "a management layer that doesn't appear to understand what works for its product nor which parts of it matter most to users..." "Steven's core point is correct. Firefox is in a bit of a mess — but, seriously, not such a bad mess. You're still better off with it — or one of its forks, because this is FOSS — than pretty much any of the alternatives." Like many things, unfortunately, much of computing is run on feelings, tradition, and group loyalties, when it should use facts, evidence, and hard numbers. Don't bother saying Firefox is getting slower. It's not. It's faster than it has been in years. Phoronix, the go-to site for benchmarks on FOSS stuff, just benchmarked 21 versions, and from late 2023 to now, Firefox has steadily got faster and faster... Ever since Firefox 1.0 in 2004, Firefox has never had to compete. It's been attached like a mosquito to an artery to the Google cash firehose... Mozilla's leadership is directionless and flailing because it's never had to do, or be, anything else. It's never needed to know how to make a profit, because it never had to make a profit. It's no wonder it has no real direction or vision or clue: it never needed them. It's role-playing being a business. Like we said, don't blame the app. You're still better off with Firefox or a fork such as Waterfox. Chrome even snoops on you when in incognito mode... One observer has been spectating and commentating on Mozilla since before it was a foundation — one of its original co-developers, Jamie Zawinksi... Zawinski has repeatedly said: "Now hear me out, but What If...? browser development was in the hands of some kind of nonprofit organization?" "In my humble but correct opinion, Mozilla should be doing two things and two things only: — Building THE reference implementation web browser, and — Being a jugular-snapping attack dog on standards committees. — There is no 3." Perhaps this is the only viable resolution. Mozilla, for all its many failings, has invented a lot of amazing tech, from Rust to Servo to the leading budget phone OS. It shouldn't be trying to capitalize on this stuff. Maybe encourage it to have semi-independent spinoffs, such as Thunderbird, and as KaiOS ought to be, and as Rust could have been. But Zawinski has the only clear vision and solution we've seen yet. Perhaps he's right, and Mozilla should be a nonprofit, working to fund the one independent, non-vendor-driven, standards-compliant browser engine.

NVIDIA Warns Its High-End GPUs May Be Vulnerable to Rowhammer Attacks

12 juillet 2025 à 21:34
Slashdot reader BrianFagioli shared this report from Nerds.xyz: NVIDIA just put out a new security notice, and if you're running one of its powerful GPUs, you might want to pay attention. Researchers from the University of Toronto have shown that Rowhammer attacks, which are already known to affect regular DRAM, can now target GDDR6 memory on NVIDIA's high-end GPUs when ECC [error correction code] is not enabled. They pulled this off using an A6000 card, and it worked because system-level ECC was turned off. Once it was switched on, the attack no longer worked. That tells you everything you need to know. ECC matters. Rowhammer has been around for years. It's one of those weird memory bugs where repeatedly accessing one row in RAM can cause bits to flip in another row. Until now, this was mostly a CPU memory problem. But this research shows it can also be a GPU problem, and that should make data center admins and workstation users pause for a second. NVIDIA is not sounding an alarm so much as reminding everyone that protections are already in place, but only if you're using the hardware properly. The company recommends enabling ECC if your GPU supports it. That includes cards in the Blackwell, Hopper, Ada, and Ampere lines, along with others used in DGX, HGX, and Jetson systems. It also includes popular workstation cards like the RTX A6000. There's also built-in On-Die ECC in certain newer memory types like GDDR7 and HBM3. If you're lucky enough to be using a card that has it, you're automatically protected to some extent, because OD-ECC can't be turned off. It's always working in the background. But let's be real. A lot of people skip ECC because it can impact performance or because they're running a setup that doesn't make it obvious whether ECC is on or off. If you're not sure where you stand, it's time to check. NVIDIA suggests using tools like nvidia-smi or, if you're in a managed enterprise setup, working with your system's BMC or Redfish APIs to verify settings.

Robinhood Up 160% in 2025, But May Face Obstacles

12 juillet 2025 à 20:34
Robinhood's stock hit is up more than 160% for 2025, reports CNBC, and the trading platform's own stock hit an all-time high on Friday. But "Despite its stellar year, the online broker is facing several headwinds..." Florida Attorney General James Uthmeier opened a formal investigation into Robinhood Crypto on Thursday, alleging the platform misled users by claiming to offer the lowest-cost crypto trading. "Robinhood has long claimed to be the best bargain, but we believe those representations were deceptive," Uthmeier said in a statement. The probe centers on Robinhood's use of payment for order flow — a common practice where market makers pay to execute trades — which the AG said can result in worse pricing for customers. Robinhood is also facing opposition to a new 25% cut of staking rewards for U.S. users, set to begin October 1. In Europe, the platform will take a smaller 15% cut. Staking allows crypto holders to earn yield by locking up their tokens to help secure blockchain networks like ethereum, but platforms often take a percentage of those rewards as commission. Robinhood's 25% cut puts it in line with Coinbase, which charges between 25.25% and 35% depending on the token. The cut is notably higher than Gemini's flat 15% fee. It marks a shift for the company, which had previously steered clear of staking amid regulatory uncertainty... The company now offers blockchain-based assets in Europe that give users synthetic exposure to private firms like OpenAI and SpaceX through special purpose vehicles, or SPVs. An SPV is a separate entity that acquires shares in a company. Users then buy tokens of the SPV and don't have shareholder privileges or voting rights directly in the company. OpenAI has publicly objected, warning the tokens do not represent real equity and were issued without its approval... "What's important is that retail customers have an opportunity to get exposure to this asset," [Robinhood CEO Vlad Tenev said in an interview with CNBC], pointing to the disruptive nature of AI and the historically limited access to pre-IPO companies. "It is true that these are not technically equity," Tenev added, noting that institutional investors often gain similar exposure through structured financial instruments... Despite the regulatory noise, many investors remain focused on Robinhood's upside, and particularly the political tailwinds.

Northern Arizona Resident Dies From Plague

12 juillet 2025 à 19:34
It killed tens of millions of people in 14th century Europe," CNN reports, though "today, it's easily treated with antibiotics." And yet "A resident of northern Arizona has died from pneumonic plague, health officials said Friday." Plague is rare to humans, with on average about seven cases reported annually in the U.S., most of them in the western states, according to federal health officials. The death in Coconino County, which includes Flagstaff, was the first recorded death from pneumonic plague since 2007, local officials said... The bubonic plague is the most common form of the bacterial infection, which spreads naturally among rodents like prairie dogs and rats. There are two other forms: septicemic plague that spreads through the whole body, and pneumonic plague that infects the lungs. Pneumonic plague is the most deadly and easiest to spread.

Microsoft Outlook Malfunctioned For Over 21 Hours Wednesday and Thursday

12 juillet 2025 à 18:34
"Microsoft's Outlook email service malfunctioned for over 21 hours Wednesday and Thursday," reports CNBC, "prompting some people to post on social media about the inability to reach their virtual mailboxes." The issue began at 6:20 p.m. Eastern time on Wednesday, according to a dashboard the software company maintains. It affected Outlook.com as well as Outlook mobile apps and desktop programs. At 12:21 ET on Thursday, the Microsoft 365 Status account posted that it was rolling out a fix. Although earlier on Thursday Microsoft posted on X that "We identified an issue with the initial fix, and we've corrected it..." More details from the Associated Press: Disruptions appeared to peak just before noon ET on Thursday, when more than 2,700 users worldwide reported issues with Outlook, formerly also Hotmail, to outage tracker Downdetector. Some said they encountered problems like loading their inboxes or signing in. By later in the afternoon, reports had fallen to just over a couple hundred... Microsoft did not immediately provide more information about what had caused the hourslong outage. A spokesperson for Microsoft had no further comment when reached by The Associated Press on Thursday.

Much of the World's Solar Gear is Made Using Fossil Power in China

12 juillet 2025 à 17:34
China "accounts for more than half of global coal use," reports Asia Times, "even as it builds the world's largest solar-panel and EV industries." Much of the world's solar gear is made on fossil power. The International Energy Agency finds that "coal generates over 60% of the electricity used for global solar PV manufacturing," far above coal's ~36% share of typical grids. That is because over 80% of PV factories sit in Chinese provinces like Xinjiang and Jiangsu, where coal dominates the grid. China has poured over $50 billion into solar factories since 2011, roughly ten times Europe's investment, cutting panel costs by about 80% and fueling a worldwide solar boom. But those panels were produced on coal. In one analysis, they repay their manufacturing CO2 in only months, meaning the emissions were dumped up-front in China's coal plants. Any major disruption to China's coal power or factories (from grid shocks to trade barriers) could thus send ripples through the global PV market. China's coal and heavy industries also feed its clean-tech supply chain. Coal-fired steel mills supply the aluminum and metal parts for EVs and panels, and coal chemicals provide battery precursors and silicon for solar... At the same time, Chinese oil and gas giants (CNPC, Sinopec) have set up solar, wind and battery divisions, redirecting fossil profits into green ventures. Another interesting statistic from the article: "In Thailand, Asia's long-time auto hub, Chinese EV brands now command more than 70% of EV sales." Thanks to Slashdot reader RossCWilliams for sharing the news.

Bitcoin Hits an All-Time High of $118,000, Up 21% for 2025

12 juillet 2025 à 16:34
Bitcoin "vaulted to a fresh all-time high Friday, breaking above $118,000," reports Yahoo Finance: Year to date, the token is up roughly 21%, buoyed in part by crypto-friendly policies from the Trump administration, including the establishment of a strategic bitcoin reserve and a broader digital asset stockpile... "At the heart of this rally lies sustained structural inflows from institutional players," wrote Dilin Wu, research strategist at Pepperstone. "Corporates are also ramping up participation," he added. The analyst noted companies like Strategy and GameStop have continued to add bitcoin to their balance sheets. Trump Media & Technology Group this week also filed for approval to launch a "Crypto Blue Chip ETF", which would include about 70% of its holdings in bitcoin. The timing of bitcoin's breakout also comes days before Congress kicks off its highly anticipated "Crypto Week" on July 14. Lawmakers will debate a series of bills that could define the industry's regulatory framework... The GENIUS Act is among the regulations the House will consider. The bill, which recently passed through the Senate, proposes a federal framework for stablecoins. "After jumping above $118,000 on Thursday, technical analyst Katie Stockton, founder and managing partner of research firm Fairlead Strategies, believes bitcoin is on track to reach $134,500, about 14% higher than current levels," writes Business Insider . It's not just bitcoin that's jumped this week. Other cryptos are surging as well. Ethereum has rallied over 16% in the past five days, and as DOGE rose 8% in the last day alone... Additionally, over $1 billion in short positions were liquidated in the last 24 hours as the price of bitcoin surged and traders were forced to close their positions, [said Thomas Perfumo, global economist at crypto Kraken].
