Is Enron Transforming Into a Real Texas Retail Electricity Provider?

13 juillet 2025 à 18:47
HGP Storage is a (real) Texas company providing distributed battery-based, utility-scale energy storage systems. Founded in 2013, it has "successfully developed over 20+ sites and closed over 200 MW of distributed energy projects," according to its web site. And they just teamed up with Enron, reports the Houston Chronicle: The company that took over the defunct Enron brand, led by a "Birds Aren't Real" cofounder [28-year-old Connor Gaydos], held a mostly satirical quarterly earnings call Thursday afternoon but gave updates to an application to become a legitimate Texas energy provider... DJ Withee, chief operating officer and legal counsel at HGP Storage, a company developing utility-scale battery storage farms, was introduced as Enron's vice president of energy service. Withee said he was brought on by Gaydos to set up the customer-facing energy services business. Enron Energy Texas LLC, a subsidiary of Enron, filed to become a Texas retail electric provider in January. Gaining this designation would allow Enron to sell electricity plans to Texas consumers. "Our business model is actually going to be very simple," Withee said. "We buy wholesale electricity, just like everybody else, but because of our efficiency, because of our use of technology, we are going to have lower costs than our competitors. Lower costs means greater savings that we can pass back to our customers...." According to Withee, Enron's goal is to provide energy at a competitive lower cost that will not only make energy more accessible but also push other Texas retail companies to drop their own prices... Enron's filing in January included sworn and notarized affidavits from a man named Gregory Forero, who was identified in the documents as vice president of Enron Texas Energy LLC. Forero is the founder and CEO of HGP Storage. "Forero, who signed his name to three sworn affidavits attesting to the accuracy of the application, could risk perjury charges if the statements of intention to start a legitimate retail electric company are found to be false, according to the Texas Penal Code..." But does this replace Enron's plans to sell egg-shaped home nuclear reactors?

Some Gut Microbes Can Absorb and Help Expel 'Forever Chemicals', Study Shows

13 juillet 2025 à 17:47
"Certain kinds of gut microbes absorb toxic Pfas 'forever chemicals' and help expel them from the body," reports the Guardian, citing a "new first-of-its-kind University of Cambridge research shows." The microbes were found to remove up to 75% of some Pfas from the gut of mice. Several of the study's authors plan to develop probiotic dietary supplements that boost levels of helpful microbes in the human gut, which would likely reduce Pfas levels... Pfas are a class of about 15,000 compounds most frequently used to make products water-, stain- and grease-resistant. They have been linked to cancer, birth defects, decreased immunity, high cholesterol, kidney disease and a range of other serious health problems. They are dubbed "forever chemicals" because they do not naturally break down in the environment. The US Environmental Protection Agency has found no level of exposure to Pfos or Pfoa, two of the most common Pfas compounds, in drinking water is safe. They have a half-life in human blood of anywhere from two to five years, by most estimates. That means the body expels half the amount of the chemical that is in blood during that period. Depending on blood levels, it can take decades to fully expel Pfas naturally. Though the findings represent the first time gut microbes have been found to remove Pfas, they have been found to alleviate the impacts of other contaminants, such as microplastics... The microbes largely addressed "long-chain" Pfas, which are larger compounds and more dangerous than smaller "short chains" because they stay in the body longer.

Underwater Turbine Spins 6.5 Years Off Scotland's Coast, Proving Viability of Tidal Energy

13 juillet 2025 à 16:34
An underwater turbine has been spinning for more than six years "to harness the power of ocean tides for electricity," reports the Associated Press. The long-running turbine (off the coast of Scotland) has now proven the commercial viability of the technology: Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy Europe. Tidal energy projects would be prohibitively expensive if the turbines had to be taken out of the water for maintenance every couple of years. Tidal energy technologies are still in the early days of their commercial development, but their potential for generating clean energy is big. According to the National Renewable Energy Laboratory, marine energy, a term researchers use to refer to power generated from tides, currents, waves or temperature changes, is the world's largest untapped renewable energy resource. This long-running tidal energy project off the coast of Scotland has four 1.5-megawatt turbines — enough to power 7,000 homes for a year, according to the article. But they plan to add 20 turbines in 2030 ("after needed upgrades to the electricity grid are finished"), and the site "could eventually hold as many as 130 turbines that are more powerful than those at the site today." Thanks to Slashdot reader Bruce66423 for sharing the news.

China's Omoway Announces a New Self-Driving Electric Scooter Named 'Omo X'

13 juillet 2025 à 15:34
Electrek reports on the new Omo X, a scooter planned for release in 2026 that's "full of premium tech features that blur the lines between e-scooter and self-driving EV." At its recent launch in Jakarta, the Omo X didn't just sit pretty center stage, it actually drove itself onto the stage using its "Halo Pilot" system, which apparently comes complete with adaptive cruise control, remote summon, self-parking, and even automatic reversing and self-balancing at low speeds. This is legit autonomous behavior previously reserved for cars, now shrunk down and smoothed out for a two-wheeler. Under the hood — or rather, behind the sleek bodywork — Omoway's Halo architecture delivers collision warning, emergency-brake assist, blind spot monitoring, and V2V [vehicle-to-vehicle] communication. The frame is modular, too. It can be reconfigured in step-through, straddle, or touring posture to suit casual riders, commuters, and motorcycle wannabes alike. That kind of flexibility isn't just a marketing gimmick, but rather it looks purpose-built to capture diverse motorcycle-heavy markets like Indonesia, which counts over 120 million two-wheelers and is quickly transitioning to electric models... It's tech-rich, head-turning, and seems built to evolve with software updates. The remote summon and AI-assisted features could genuinely simplify urban mobility, and tricks like automatically driving itself to a charging station sound legitimately useful... [But] Omoway's vision here will have to carry extra sensors, actuators, and redundant systems to support those smart functions. With added costs and complexity, will riders in developing markets pay a premium, carry extra maintenance risk, or worry about obsolescence? Much hinges on Omoway's software support and local service networks. The article reports a projected price around €3,500 (roughly $3,800). "And while Indonesia may have been the launchpad, global markets aren't off the table..."

Nintendo Banned Switch 2 Owner For Playing a Used Switch 1 Game They Bought Online

13 juillet 2025 à 14:34
"A Nintendo Switch 2 user reportedly got his brand-new console banned by Nintendo after buying used Switch 1 games and patching them on his console," reports Tom's Hardware: According to Reddit user dmanthey, they purchased four used titles off the Facebook marketplace, inserted them into the Switch 2, and had them all updated. When they turned on their handhelds the following day, they received a message saying that they were restricted from Nintendo's online services and that they couldn't even download the games they had already bought... [T]hey were able to prove their innocence by pulling up the Facebook Marketplace listing for their games and sending the photos of their purchased cartridges. According to the Redditor, the process was painless and fast, and it was "so much easier than getting support from Microsoft or Sony...." Other users warned, though, that this isn't always a guaranteed resolution. Nintendo is known for being protective of its intellectual property and delivers harsh penalties to anyone caught violating it. We've already had several reports of users getting banned for using Mig Flash, even on their own ROMs. And while it's not true that getting banned turns your Switch 2 into a brick, it will still prevent you from accessing the company's online services, which severely restricts its features and usability. "Nintendo attaches unique codes to its Switch game cartridges to prevent piracy," notes Engadget. "However, bad actors can copy games onto a third-party device, like the MIG Flash, and then resell the physical game card. Once Nintendo detects two instances of its unique code being online at the same time, it will ban any accounts using it..." This anti-piracy policy isn't new — Nintendo has long had a reputation for fiercely combating any type of piracy — but it has become relevant again thanks to the recently released Switch 2, which offers backwards compatibility with original Switch titles. The company even recently amended its user agreement to allow itself the power to brick a Nintendo Switch that's caught running pirated games or mods.

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.
