More than 50 years after its debut, Uno has achieved unprecedented popularity among adults, but its resurgence is creating problems and confusions as players disagree on fundamental rules. WSJ, in a fun story [non-paywalled source]: Think politics divides? Try mixing competitors with different views on stacking "action" cards, or getting everyone to agree on the true power of the Wild card. And nobody can seem to decide whether staples of the game of their youth -- like mandating players yell "Uno!" when they have one card left -- are socially acceptable at a bar with strangers. Mattel has responded by actively settling rule debates on social media, definitively stating that stacking Draw 2 cards is prohibited, while simultaneously embracing the game's divisive nature through marketing campaigns. The company's "Show 'Em No Mercy" variant, featuring more aggressive rules, became the second-best-selling card game in the United States last year according to research firm Circana, trailing only classic Uno itself.

Pakistan will allocate 2,000 megawatts (MW) of electricity in the first phase of a national initiative to power bitcoin mining and AI data centres, its finance ministry said on Sunday. The allocation is part of Islamabad's plans to use its surplus electricity to bitcoin mining and AI data centres.

Whether General Motors survives "depends in part on whether its bets on battery technology pay off," writes the Wall Street Journal.

At $33,600 the company's Chevy Equinox is one of the cheapest EVs in America (only $5,000 more than the gas-powered model). "But it also recently announced a novel type of battery that promises to be significantly cheaper, while still providing long range, due to be rolled out in 2028..." Like many of its competitors, GM has made huge investments in EV battery factories, and in production lines for the vehicles themselves, and it faces challenges in generating a return on investment in the short term... In the long run, however, GM's focus on creating a North American supply chain for batteries could prove savvy, says David Whiston, U.S. auto equities analyst at Morningstar. The company is investing $625 million to mine lithium in Nevada. It is working on sourcing every material and every part in its batteries domestically, down to the copper and aluminum foils that go into its cells, says [battery and sustainability lead Kurt] Kelty...

GM recently unveiled a new type of battery the company has been working on for a decade called lithium manganese-rich batteries, or LMR. These batteries combine the low cost of LFP batteries with the longer range of conventional, expensive lithium-ion batteries. What makes LMR batteries more affordable is that they use far less nickel, cobalt and other minerals that have become increasingly expensive. Instead, they use more manganese, a common element... The company's next initiative, says Kelty, is to further drive down the cost of its batteries by putting more of another common element, silicon, into them.
"If GM can continue to grow demand for its EVs, in a few years the rollout of its latest tech could give it a price and performance advantage..." the article points out. While the EV transition is happening more slowly than projected in the U.S., GM hiring Kelty is a bet that the country's current EV struggles are temporary, and that technologists like Kelty will help GM get past them. "When we reach cost parity with [internal combustion engine] vehicles, I think that's one big milestone," says Kelty. "When you get there, then you're really going to see the transition happen very quickly — and we're not that far away from it."

"In the 1970s, the USSR used nuclear devices to try to send water from Siberia's rivers flowing south, instead of its natural route north..." remembers the BBC. [T]he Soviet Union simultaneously fired three nuclear devices buried 127m (417ft) underground. The yield of each device was 15 kilotonnes (about the same as the atomic bomb dropped on Hiroshima in 1945). The experiment, codenamed "Taiga", was part of a two-decade long Soviet programme of carrying out peaceful nuclear explosions (PNEs).

In this case, the blasts were supposed to help excavate a massive canal to connect the basin of the Pechora River with that of the Kama, a tributary of the Volga. Such a link would have allowed Soviet scientists to siphon off some of the water destined for the Pechora, and send it southward through the Volga. It would have diverted a significant flow of water destined for the Arctic Ocean to go instead to the hot, heavily populated regions of Central Asia and southern Russia. This was just one of a planned series of gargantuan "river reversals" that were designed to alter the direction of Russia's great Eurasian waterways...

Years later, Leonid Volkov, a scientist involved in preparing the Taiga explosions, recalled the moment of detonation. "The final countdown began: ...3, 2, 1, 0... then fountains of soil and water shot upward," he wrote. "It was an impressive sight." Despite Soviet efforts to minimise the fallout by using a low-fission explosive, which produce fewer atomic fragments, the blasts were detected as far away as the United States and Sweden, whose governments lodged formal complaints, accusing Moscow of violating the Limited Test Ban Treaty...

Ultimately, the nuclear explosions that created Nuclear Lake, one of the few physical traces left of river reversal, were deemed a failure because the crater was not big enough. Although similar PNE canal excavation tests were planned, they were never carried out. In 2024, the leader of a scientific expedition to the lake announced radiation levels were normal.
"Perhaps the final nail in the coffin was the Chernobyl nuclear disaster in 1986, which not only consumed a huge amount of money, but pushed environmental concerns up the political agenda," the article notes.

"Four months after the Number Four Reactor at the Chernobyl Nuclear Power Plant exploded, Soviet Premier Mikhail Gorbachev cancelled the river reversal project."

And a Russian blogger who travelled to Nuclear Lake in the summer of 2024 told the BBC that nearly 50 years later, there were some places where the radiation was still significantly elevated.

Doom: The Dark Ages just launched on May 15. But it's already received "difficulty" balance changes "that have made the demons of Hell even more dangerous than ever," writes Windows Central: According to DOOM's official website Slayer's Club, these balance adjustments are focused on making the game harder, as players have been leaving feedback saying it felt too easy even on Nightmare Mode. As a result, enemies now hit harder, health and armor item pick-ups drop less often, and certain enemies punish you more severely for mistiming the parry mechanic.
It reached three million players in just five days, which was seven times faster than 2020's Doom: Eternal," reports Wccftech (though according to analytics firm Ampere Analysis (via The Game Business), more than two million of those three million launch players were playing on Xbox, while only 500K were playing on PS5.") "id Software proves it can still reinvent the wheel," according to one reviewer, "shaking up numerous aspects of gameplay, exchanging elaborate platforming for brutal on-the-ground action, as well as the ability to soar on a dragon's back or stomp around in a giant mech."

And the New York Times says the game "effectively reinvents the hellish shooter with a revamped movement system and deepened lore" in the medieval goth-themed game... Double jumping and dashing are ditched and replaced with an emphasis on raw power and slow, strategic melee combat. Doom Slayer's arsenal features a brand-new tool, the powerful Shield Saw, which Id Software made a point to showcase across its "Stand and Fight" trailers and advertisements. Used for absorbing damage at the expense of speed, the saw also allows players to bash enemies from afar and close the gap on chasms too wide to jump across. While previous titles allowed players to quickly worm their way through bullet hell, The Dark Ages expects you to meet foes head on. "If you were an F-22 fighter jet in Doom Eternal, this time around we wanted you to feel like an Abrams tank," Hugo Martin, the game's creative director, has told journalists.

And Doom Slayer's beefy durability and unstoppable nature does make the gameplay a refreshing experience. The badassery is somehow ratcheted to new heights with the inclusion of a fully controllable mech, which has only a handful of attacks at its disposal, and actual dragons. Flight in a Doom game is entirely surprising and fluid, and the dragons feel relatively easy to maneuver through tight spots. They can also engage in combat more deliberately with the use of dodges and mounted cannons...

One of my favorite additions is the skullcrusher pulverizer. Equal parts heinous nutcracker and demonic woodchipper, the gun lodges skulls into a grinder and sends shards of bones flying at enemies. The animation is both goofy and satisfying.
Another special Times article notes that Doom's fans "resurrect the original game over and over again on progressively stranger pieces of hardware: a Mazda Miata, a NordicTrack treadmill, a French pharmacy sign." But what many hard-core tech hobbyists want to know is whether you can play it on a pregnancy test. The answer: positively yes. And for the first time, even New York Times readers can play Doom within The Times's site [after creating a free account]...

None of this happened by accident, of course. Ports were not incidental to Doom's development. They were a core consideration. "Doom was developed in a really unique way that lent a high degree of portability to its code base," said John Romero, who programmed the game with John Carmack. (In our interview, he then reminisced about operating systems for the next 14 minutes.) Id had developed Wolfenstein 3D, the Nazi-killing predecessor to Doom, on PCs. To build Doom, Carmack and Romero used NeXT, the hardware and software company founded by Steve Jobs after his ouster from Apple in 1985. NeXT computers were powerful, selling for about $25,000 apiece in today's dollars. And any game designed on that system would require porting to the more humdrum PCs encountered by consumers at computer labs or office jobs.

This turned out to be advantageous because Carmack had a special aptitude for ports. All of Id's founders met as colleagues at Softdisk, which had hired Carmack because of his ability to spin off multiple versions of a single game. The group decided to strike out on its own after Carmack created a near-perfect replica of the first level of Super Mario Bros. 3 — Nintendo's best-selling platformer — on a PC. It was a wonder of software engineering that compensated for limited processing power with clever workarounds. "This is the thing that everyone has," Romero said of PCs. "The fact that we could figure out how to make it become a game console was world changing...."

Romero founded a series of game studios after leaving Id in 1996 and is working on a new first-person shooter, the genre he and Carmack practically invented. He has no illusions about how it may stack up. "I absolutely accept that Doom is the best game I'll ever make that has that kind of a reach," he said. "At some point you make the best thing." Thirty years on, people are still making it.
And in related news, PC Gamer reports... As part of a new "FPS Fridays" series on Twitch, legendary shooter designer John Romero streamed New Blood's 2018 hit, Dusk, one of the first and most influential indie "boomer shooters" in the genre's recent revitalization. The short of it? Romero seems to have had a blast.

"What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors?" asks the University of Arizona.

"A team of scientists, including researchers from the University of Arizona, are working to make that possible." In a groundbreaking international effort, researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences demonstrated a way to manipulate electrons in graphene using pulses of light that last less than a trillionth of a second. By leveraging a quantum effect known as tunneling, they recorded electrons bypassing a physical barrier almost instantaneously, a feat that redefines the potential limits of computer processing power. A study published in Nature Communications highlights how the technique could lead to processing speeds in the petahertz range — over 1,000 times faster than modern computer chips. Sending data at those speeds would revolutionize computing as we know it, said Mohammed Hassan, an associate professor of physics and optical sciences. Hassan has long pursued light-based computer technology and previously led efforts to develop the world's fastest electron microscope...

[T]he researchers used a laser that switches off and on at a rate of 638 attoseconds to create what Hassan called "the world's fastest petahertz quantum transistor... For reference, a single attosecond is one-quintillionth of a second," Hassan said. "That means that this achievement represents a big leap forward in the development of ultrafast computer technologies by realizing a petahertz-speed transistor." While some scientific advancements occur under strict conditions, including temperature and pressure, this new transistor performed in ambient conditions — opening the way to commercialization and use in everyday electronics. Hassan is working with Tech Launch Arizona, the office that works with investigators to commercialize inventions stemming from U of A research in order to patent and market innovations.

While the original invention used a specialized laser, the researchers are furthering development of a transistor compatible with commercially available equipment. "I hope we can collaborate with industry partners to realize this petahertz-speed transistor on a microchip," Hassan said.

SiFive was one of the first companies to produce a RISC-V chip. This week they announced a new collaboration with Red Hat "to bring Red Hat Enterprise Linux support to the rapidly growing RISC-V community" and "prepare Red Hat's product portfolio for future intersection with RISC-V server hardware from a diverse set of RISC-V suppliers."

Red Hat Enterprise Linux 10 is available in developer preview on the SiFive HiFive Premier P550 platform, which they call "a proven, high performance RISC-V CPU development platform." The SiFive HiFive Premier P550 provides a proven, high performance RISC-V CPU development platform. Adding support for Red Hat Enterprise Linux 10, the latest version of the world's leading enterprise Linux platform, enables developers to create, optimize, and release new applications for the next generation of enterprise servers and cloud infrastructure on the RISC-V architecture...

SiFive's high performance RISC-V technology is already being used by large organizations to meet compute-intensive AI and machine learning workloads in the datacenter... "With the growing demand for RISC-V, we are pleased to collaborate with SiFive to support Red Hat Enterprise Linux 10 deployments on SiFive HiFive Premier P550," said Ronald Pacheco, senior director of RHEL product and ecosystem strategy, "to further empower developers with the power of the world's leading enterprise Linux platform wherever and however they choose to deploy...."

Dave Altavilla, principal analyst at HotTech Vision And Analysis, said "Native Red Hat Enterprise Linux support on SiFive's HiFive Premier P550 board offers developers a substantial enterprise-grade toolchain for RISC-V.

"This is a pivotal step forward in enabling a full-stack ecosystem around open RISC-V hardware. SiFive says the move will "inspire the next generation of enterprise workloads and AI applications optimized for RISC-V," while helping their partners "deliver systems with a meaningfully lower total cost of ownership than incumbent platforms."

"With the growing demand for RISC-V, we are pleased to collaborate with SiFive to support Red Hat Enterprise Linux 10 deployments on SiFive HiFive Premier P550..." said Ronald Pacheco, senior director of RHEL product and ecosystem strategy. .

Beta News notes that there's also a new AI-powered assistant in RHEL 10, so "Instead of spending all day searching for answers or poking through documentation, admins can simply ask questions directly from the command line and get real-time help Security is front and center in this release, too. Red Hat is taking a proactive stance with early support for post-quantum cryptography. OpenSSL, GnuTLS, NSS, and OpenSSH now offer quantum-resistant options, setting the stage for better protection as threats evolve. There's a new sudo system role to help with privilege management, and OpenSSH has been bumped to version 9.9. Plus, with new Sequoia tools for OpenPGP, the door is open for even more robust encryption strategies. But it's not just about security and AI. Containers are now at the heart of RHEL 10 thanks to the new "image mode." With this feature, building and maintaining both the OS and your applications gets a lot more streamlined...

In early 2025, U.S. solar power production jumped 44% compared to the previous year, driven by end-of-year construction to capture tax incentives and long-term cost advantages. "The bad news is that, in contrast to China, solar's growth hasn't been enough to offset rising demand," notes Ars Technica. "Instead, the US also saw significant growth in coal use, which rose by 23 percent compared to the year prior, after years of steady decline." From the report: Short-term fluctuations in demand are normal, generally driven by weather-induced demand for heating or cooling. Despite those changes, demand for electricity in the US has been largely flat for over a decade, largely thanks to gains in efficiency. But 2024 saw demand go up by nearly 3 percent, and the first quarter of 2025 saw another rise, this time of nearly 5 percent. It's a bit too early to say that we're seeing a shift to a period of rising demand, but one has been predicted for some time due to rising data center use and the increased electrification of transportation and appliances.

Under those circumstances, the rest of the difference will be made up for with fossil fuels. Running counter to recent trends, the use of natural gas dropped during the first three months of 2025. This means that the use of coal rose nearly as quickly as demand, up by 23 percent compared to the same time period in 2024. Despite the rise in coal use, the fraction of carbon-free electricity held steady year over year, with wind/solar/hydro/nuclear accounting for 43 percent of all power put on the US grid. That occurred despite small drops in nuclear and hydro production.

Longtime Slashdot reader sinij shares a press release from the White House, outlining a series of executive orders that overhaul the Nuclear Regulatory Commission and speed up deployment of new nuclear power reactions in the U.S.. From a report: The NRC is a 50-year-old, independent agency that regulates the nation's fleet of nuclear reactors. Trump's orders call for a "total and complete reform" of the agency, a senior White House official told reporters in a briefing. Under the new rules, the commission will be forced to decide on nuclear reactor licenses within 18 months. Trump said Friday the orders focus on small, advanced reactors that are viewed by many in the industry as the future. But the president also said his administration supports building large plants. "We're also talking about the big plants -- the very, very big, the biggest," Trump said. "We're going to be doing them also."

When asked whether NRC reform will result in staff reductions, the White House official said "there will be turnover and changes in roles." "Total reduction in staff is undetermined at this point, but the executive orders do call for a substantial reorganization" of the agency, the official said. The orders, however, will not remove or replace any of the five commissioners who lead the body, according to the White House. Any reduction in staff at the NRC would come at time when the commission faces a heavy workload. The agency is currently reviewing whether two mothballed nuclear plants, Palisades in Michigan and Three Mile Island in Pennsylvania, should restart operations, a historic and unprecedented process. [...]

Trump's orders also create a regulatory framework for the Departments of Energy and Defense to build nuclear reactors on federal land, the administration official said. "This allows for safe and reliable nuclear energy to power and operate critical defense facilities and AI data centers," the official told reporters. The NRC will not have a direct role, as the departments will use separate authorities under their control to authorize reactor construction for national security purposes, the official said. The president's orders also aim to jump start the mining of uranium in the U.S. and expand domestic uranium enrichment capacity, the official said. Trump's actions also aim to speed up reactor testing at the Department of Energy's national laboratories.

Spain's grid operator has accused some large power plants of not doing their job to help regulate the country's electricity system in the moments before last month's catastrophic blackout across the Iberian peninsula. From a report: Beatriz Corredor, chair of grid operator Red Electrica's parent company, said power plants fell short in controlling the voltage of the electricity system.

However, the heads of Spain's biggest plant owners linked the blackout to a lack of grid investment and insufficient efforts to boost electricity demand. The public blame game over the outage is intensifying as more than three weeks after 60 million people were left without power, Spanish government investigators insisted they needed more time to establish the root cause.

An anonymous reader quotes a report from Phys.Org: Neuroscientists and materials scientists have created contact lenses that enable infrared vision in both humans and mice by converting infrared light into visible light. Unlike infrared night vision goggles, the contact lenses, described in the journal Cell, do not require a power source -- and they enable the wearer to perceive multiple infrared wavelengths. Because they're transparent, users can see both infrared and visible light simultaneously, though infrared vision was enhanced when participants had their eyes closed. [...] The contact lens technology uses nanoparticles that absorb infrared light and convert it into wavelengths that are visible to mammalian eyes (e.g., electromagnetic radiation in the 400-700 nm range). The nanoparticles specifically enable the detection of "near-infrared light," which is infrared light in the 800-1600 nm range, just beyond what humans can already see.

The team previously showed that these nanoparticles enable infrared vision in mice when injected into the retina, but they wanted to design a less invasive option. To create the contact lenses, the team combined the nanoparticles with flexible, nontoxic polymers that are used in standard soft contact lenses. After showing that the contact lenses were nontoxic, they tested their function in both humans and mice. They found that contact lens-wearing mice displayed behaviors suggesting that they could see infrared wavelengths. For example, when the mice were given the choice of a dark box and an infrared-illuminated box, contact-wearing mice chose the dark box whereas contact-less mice showed no preference. The mice also showed physiological signals of infrared vision: the pupils of contact-wearing mice constricted in the presence of infrared light, and brain imaging revealed that infrared light caused their visual processing centers to light up. In humans, the infrared contact lenses enabled participants to accurately detect flashing morse code-like signals and to perceive the direction of incoming infrared light.

An additional tweak to the contact lenses allows users to differentiate between different spectra of infrared light by engineering the nanoparticles to color-code different infrared wavelengths. For example, infrared wavelengths of 980 nm were converted to blue light, wavelengths of 808 nm were converted to green light, and wavelengths of 1,532 nm were converted to red light. In addition to enabling wearers to perceive more detail within the infrared spectrum, these color-coding nanoparticles could be modified to help color-blind people see wavelengths that they would otherwise be unable to detect. [...] Because the contact lenses have limited ability to capture fine details (due to their close proximity to the retina, which causes the converted light particles to scatter), the team also developed a wearable glass system using the same nanoparticle technology, which enabled participants to perceive higher-resolution infrared information. Currently, the contact lenses are only able to detect infrared radiation projected from an LED light source, but the researchers are working to increase the nanoparticles' sensitivity so that they can detect lower levels of infrared light.

New analysis by MIT Technology Review reveals AI's rapidly growing energy demands, with data centers expected to triple their share of US electricity consumption from 4.4% to 12% by 2028. According to Lawrence Berkeley National Laboratory projections, AI alone could soon consume electricity equivalent to 22% of all US households annually, driven primarily by inference operations that represent 80-90% of AI's computing power.

The carbon intensity of electricity used by data centers is 48% higher than the US average, researchers found, as facilities increasingly turn to dirtier energy sources like natural gas to meet immediate needs.

Tech giants are racing to secure unprecedented energy resources: OpenAI and President Trump announced a $500 billion Stargate initiative, Apple plans to spend $500 billion on manufacturing and data centers, and Google expects to invest $75 billion in AI infrastructure in 2025 alone. Despite their massive energy ambitions, leading AI companies remain largely silent about their per-query energy consumption, leaving researchers struggling to assemble what one expert called "a total black box."

An anonymous reader shares a report: Germany has dropped its long-held opposition to nuclear power, in the first concrete sign of rapprochement with France by Berlin's new government led by conservative Chancellor Friedrich Merz.

Berlin has signalled to Paris it will no longer block French efforts to ensure nuclear power is treated on par with renewable energy in EU legislation, according to French and German officials.

The move resolves a major dispute between the two countries that has delayed decisions on EU energy policy, including during the crisis that followed Russiaâ(TM)s full-scale invasion of Ukraine.

"The Danish government plans to evaluate the prospect of beginning a nuclear power programme," reports the Telegraph, noting that this week Denmark lifted a nuclear power ban imposed 40 years ago. Unlike its neighbours in Sweden and Germany, Denmark has never had a civil nuclear power programme. It has only ever had three small research reactors, the last of which closed in 2001. Most of the renewed interest in nuclear seen around the world stems from the expected growth in electricity demand from AI data centres, but Denmark is different. The Danes are concerned about possible blackouts similar to the one that struck Iberia recently. Like Spain and Portugal, Denmark is heavily dependent on weather-based renewable energy which is not very compatible with the way power grids operate... ["The spinning turbines found in fossil-fuelled energy systems provide inertia and act as a shock absorber to stabilise the grid during sudden changes in supply or demand," explains a diagram in the article, while solar and wind energy provide no inertia.]

The Danish government is worried about how it will continue to decarbonise its power grid if it closes all of its fossil fuel generators leaving minimal inertia. There are only three realistic routes to decarbonisation that maintain physical inertia on the grid: hydropower, geothermal energy and nuclear. Hydro and geothermal depend on geographic and geological features that not every country possesses. While renewable energy proponents argue that new types of inverters could provide synthetic inertia, trials have so far not been particularly successful and there are economic challenges that are difficult to resolve.

Denmark is realising that in the absence of large-scale hydroelectric or geothermal energy, it may have little choice other than to re-visit nuclear power if it is to maintain a stable, low carbon electricity grid.

"Despite many obstacles — and what you may read elsewhere — electric-vehicle sales continue to grow at a healthy pace in the U.S. market," Cox Automotive reported this week. "Roughly 7.5% of total new-vehicle sales in the first quarter were electric vehicles, an increase from 7% a year earlier."

An anonymous reader shared this analysis from Autoweek: "Despite a cloud of uncertainty around future EV interest and potential economic headwinds hanging over the automotive industry, consumer demand for electric vehicles has remained stable," according to the J.D. Power 2025 US Electric Vehicle Consideration Study released yesterday. Specifically, the study showed that 24% of vehicle shoppers in the U.S. say they are "very likely" to consider purchasing an EV and 35% say they are "somewhat likely," both of which figures remain unchanged from a year ago...

Globally the numbers are even more pro-EV. Electric car sales exceeded 17 million globally in 2024, reaching a sales share of more than 20%, according to a report issued this week by the International Energy Agency. "Just the additional 3.5 million electric cars sold in 2024 compared with the previous year is more than the total number of electric cars sold worldwide in 2020," the IEA said. China, which has mandated increases in EV sales, is the leader in getting electric vehicles on the road, with electric cars accounting for almost half of all Chinese car sales in 2024, the IEA said. "The over 11 million electric cars sold in China last year were more than global sales just 2 years earlier. As a result of continued strong growth, 1 in 10 cars on Chinese roads is now electric."
Interesting figures on U.S. EV sales from the article:

• 2024 EV sales rose 7.3% from 2023, according to Cox Automotive data.

• "Last year American consumers purchased 1.3 million electric vehicles, which was a new record, according to data from KBB.

• "Sales have never stopped growing, and the percentage of new cars sold powered purely by gasoline continues to slip.

TechCrunch reports: The world's only net-positive fusion experiment has been steadily ramping up the amount of power it produces, TechCrunch has learned.

In recent attempts, the team at the U.S. Department of Energy's National Ignition Facility (NIF) increased the yield of the experiment, first to 5.2 megajoules and then again to 8.6 megajoules, according to a source with knowledge of the experiment. The new results are significant improvements over the historic experiment in 2022, which was the first controlled fusion reaction to generate more energy than the it consumed. The 2022 shot generated 3.15 megajoules, a small bump over the 2.05 megajoules that the lasers delivered to the BB-sized fuel pellet.

None of the shots to date have been effective enough to feed electrons back into the grid, let alone to offset the energy required to power the entire facility — the facility wasn't designed to do that. The first net-positive shot, for example, required 300 megajoules to power the laser system alone. But they are continued proof that controlled nuclear fusion is more than hypothetical.

While Amazon won FAA approval to fly beyond an operators' visual line of sight, "the program remains a work in progress," reports Bloomberg: A pair of Amazon.com Inc. package delivery drones were flying through a light rain in mid-December when, within minutes of one another, they both committed robot suicide... [S]ome 217 feet (66 meters) in the air [at a drone testing facility], the aircraft cut power to its six propellers, fell to the ground and was destroyed. Four minutes later and 183 feet over the taxiway, a second Prime Air drone did the same thing.

Not long after the incidents, Amazon paused its experimental drone flights to tweak the aircraft software but said the crashes weren't the "primary reason" for halting the program. Now, five months after the twin crashes, a more detailed explanation of what happened is starting to emerge. Faulty readings from lidar sensors made the drones think they had landed, prompting the software to shut down the propellers, according to National Transportation Safety Board documents reviewed by Bloomberg. The sensors failed after a software update made them more susceptible to being confused by rain, the NTSB said.
Amazon also removed a backup sensor present that had been present on earlier iterations, according to the article — though an Amazon spokesperson said the company had found ways to replicate the removed sensors.

But Bloomberg notes Amazon's drone efforts has faced "technical challenges and crashes, including one in 2021 that set a field ablaze at the company's testing facility in Pendleton, Oregon." Deliveries are currently limited to College Station, Texas, and greater Phoenix, with plans to expand to Kansas City, Missouri, the Dallas area and San Antonio, as well as the UK and Italy. Starting with a craft that looked like a hobbyist drone — and was vulnerable to even modest gusts of wind — Amazon went through dozens of designs to toughen the vehicle and ultimately make it capable of carting about 5 pounds, giving it the capability to transport items typically ordered from its warehouses. Engineers settled on a six-propeller design that takes off vertically before cruising like a plane. The first model to make regular customer deliveries, the MK27, was succeeded last year by the MK30, which flies at about 67 miles an hour and can deliver packages up to 7.5 miles from its launch point. The craft takes off, flies and lands autonomously.

The only nuclear power plant still operating in Taiwan was shut down on Saturday, reports Japan's public media organization NHK: People in Taiwan have grown increasingly concerned about nuclear safety in recent years, especially after the 2011 nuclear disaster in Fukushima, northeastern Japan... Taiwan's energy authorities plan to focus more on thermoelectricity fueled by liquefied natural gas. They aim to source 20 percent of all electricity from renewables such as wind and solar power next year.
AFP notes that nuclear power once provided more than half of Taiwan's energy, with three plants operating six reactors across an island that's 394 km (245 mi) long and 144 km (89 mi) wide.

So the new move to close Taiwan's last reactor is "fuelling concerns over the self-ruled island's reliance on imported energy and vulnerability to a Chinese blockade," — though Taiwan's president insists the missing nucelar energy can be replace by new units in LNG and coal-fired plants: The island, which targets net-zero emissions by 2050, depends almost entirely on imported fossil fuel to power its homes, factories and critical semiconductor chip industry. President Lai Ching-te's Democratic Progressive Party has long vowed to phase out nuclear power, while the main opposition Kuomintang (KMT) party says continued supply is needed for energy security... [The Ma'anshan Nuclear Power Plant] has operated for 40 years in a region popular with tourists and which is now dotted with wind turbines and solar panels. More renewable energy is planned at the site, where state-owned Taipower plans to build a solar power station capable of supplying an estimated 15,000 households annually. But while nuclear only accounted for 4.2 percent of Taiwan's power supply last year, some fear Ma'anshan's closure risks an energy crunch....

Most of Taiwan's power is fossil fuel-based, with liquefied natural gas (LNG) accounting for 42.4 percent and coal 39.3 percent last year. Renewable energy made up 11.6 percent, well short of the government's target of 20 percent by 2025. Solar has faced opposition from communities worried about panels occupying valuable land, while rules requiring locally made parts in wind turbines have slowed their deployment.

Taiwan's break-up with nuclear is at odds with global and regional trends. Even Japan aims for nuclear to account for 20-22 percent of its electricity by 2030, up from well under 10 percent now. And nuclear power became South Korea's largest source of electricity in 2024, accounting for 31.7 percent of the country's total power generation, and reaching its highest level in 18 years, according to government data.... And Lai acknowledged recently he would not rule out a return to nuclear one day. "Whether or not we will use nuclear power in the future depends on three foundations which include nuclear safety, a solution to nuclear waste, and successful social dialogue," he said.
DW notes there's over 100,000 barrels of nuclear waste on Taiwan's easternmost island "despite multiple attempts to remove them... At one point, Taiwan signed a deal with North Korea so they could send barrels of nuclear waste to store there, but it did not work out due to a lack of storage facilities in the North and strong opposition from South Korea...

"Many countries across the world have similar problems and are scrambling to identify sites for a permanent underground repository for nuclear fuel. Finland has become the world's first nation to build one."

It's a nonprofit that's provide hosting for the Linux Foundation, the Apache Software Foundation, Drupal, Firefox, and 160 other projects — delivering nearly 430 terabytes of information every month. (It's currently hosting Debian, Fedora, and Gentoo Linux.) But hosting only provides about 20% of its income, with the rest coming from individual and corporate donors (including Google and IBM). "Over the past several years, we have been operating at a deficit due to a decline in corporate donations," the Open Source Lab's director announced in late April.

It's part of the CS/electrical engineering department at Oregon State University, and while the department "has generously filled this gap, recent changes in university funding makes our current funding model no longer sustainable. Unless we secure $250,000 in committed funds, the OSL will shut down later this year."

But "Thankfully, the call for support worked, paving the way for the OSU Open Source Lab to look ahead, into what the future holds for them," reports the blog It's FOSS.

"Following our OSL Future post, the community response has been incredible!" posted director Lance Albertson. "Thanks to your amazing support, our team is funded for the next year. This is a huge relief and lets us focus on building a truly self-sustaining OSL." To get there, we're tackling two big interconnected goals:

1. Finding a new, cost-effective physical home for our core infrastructure, ideally with more modern hardware.
2. Securing multi-year funding commitments to cover all our operations, including potential new infrastructure costs and hardware refreshes.


Our current data center is over 20 years old and needs to be replaced soon. With Oregon State University evaluating the future of this facility, it's very likely we'll need to relocate in the near future. While migrating to the State of Oregon's data center is one option, it comes with significant new costs. This makes finding free or very low-cost hosting (ideally between Eugene and Portland for ~13-20 racks) a huge opportunity for our long-term sustainability. More power-efficient hardware would also help us shrink our footprint.

Speaking of hardware, refreshing some of our older gear during a move would be a game-changer. We don't need brand new, but even a few-generations-old refurbished systems would boost performance and efficiency. (Huge thanks to the Yocto Project and Intel for a recent hardware donation that showed just how impactful this is!) The dream? A data center partner donating space and cycled-out hardware. Our overall infrastructure strategy is flexible. We're enhancing our OpenStack/Ceph platforms and exploring public cloud credits and other donated compute capacity. But whatever the resource, it needs to fit our goals and come with multi-year commitments for stability. And, a physical space still offers unique value, especially the invaluable hands-on data center experience for our students....

[O]ur big focus this next year is locking in ongoing support — think annualized pledges, different kinds of regular income, and other recurring help. This is vital, especially with potential new data center costs and hardware needs. Getting this right means we can stop worrying about short-term funding and plan for the future: investing in our tech and people, growing our awesome student programs, and serving the FOSS community. We're looking for partners, big and small, who get why foundational open source infrastructure matters and want to help us build this sustainable future together.
The It's FOSS blog adds that "With these prerequisites in place, the OSUOSL intends to expand their student program, strengthen their managed services portfolio for open source projects, introduce modern tooling like Kubernetes and Terraform, and encourage more community volunteers to actively contribute."

Thanks to long-time Slashdot reader I'm just joshin for suggesting the story.

"The altruistic OpenAI is gone, if it ever existed," argues a new article in the Atlantic, based on interviews with more than 90 current and former employees, including executives. It notes that shortly before Altman's ouster (and rehiring) he was "seemingly trying to circumvent safety processes for expediency," with OpenAI co-founder/chief scientist Ilya telling three board members "I don't think Sam is the guy who should have the finger on the button for AGI." (The board had already discovered Altman "had not been forthcoming with them about a range of issues" including a breach in the Deployment Safety Board's protocols.)

Adapted from the upcoming book, Empire of AI, the article first revisits the summer of 2023, when Sutskever ("the brain behind the large language models that helped build ChatGPT") met with a group of new researchers: Sutskever had long believed that artificial general intelligence, or AGI, was inevitable — now, as things accelerated in the generative-AI industry, he believed AGI's arrival was imminent, according to Geoff Hinton, an AI pioneer who was his Ph.D. adviser and mentor, and another person familiar with Sutskever's thinking.... To people around him, Sutskever seemed consumed by thoughts of this impending civilizational transformation. What would the world look like when a supreme AGI emerged and surpassed humanity? And what responsibility did OpenAI have to ensure an end state of extraordinary prosperity, not extraordinary suffering?

By then, Sutskever, who had previously dedicated most of his time to advancing AI capabilities, had started to focus half of his time on AI safety. He appeared to people around him as both boomer and doomer: more excited and afraid than ever before of what was to come. That day, during the meeting with the new researchers, he laid out a plan. "Once we all get into the bunker — " he began, according to a researcher who was present.

"I'm sorry," the researcher interrupted, "the bunker?"

"We're definitely going to build a bunker before we release AGI," Sutskever replied. Such a powerful technology would surely become an object of intense desire for governments globally. The core scientists working on the technology would need to be protected. "Of course," he added, "it's going to be optional whether you want to get into the bunker." Two other sources I spoke with confirmed that Sutskever commonly mentioned such a bunker. "There is a group of people — Ilya being one of them — who believe that building AGI will bring about a rapture," the researcher told me. "Literally, a rapture...."

But by the middle of 2023 — around the time he began speaking more regularly about the idea of a bunker — Sutskever was no longer just preoccupied by the possible cataclysmic shifts of AGI and superintelligence, according to sources familiar with his thinking. He was consumed by another anxiety: the erosion of his faith that OpenAI could even keep up its technical advancements to reach AGI, or bear that responsibility with Altman as its leader. Sutskever felt Altman's pattern of behavior was undermining the two pillars of OpenAI's mission, the sources said: It was slowing down research progress and eroding any chance at making sound AI-safety decisions.
"For a brief moment, OpenAI's future was an open question. It might have taken a path away from aggressive commercialization and Altman. But this is not what happened," the article concludes. Instead there was "a lack of clarity from the board about their reasons for firing Altman." There was fear about a failure to realize their potential (and some employees feared losing a chance to sell millions of dollars' worth of their equity).

"Faced with the possibility of OpenAI falling apart, Sutskever's resolve immediately started to crack... He began to plead with his fellow board members to reconsider their position on Altman." And in the end "Altman would come back; there was no other way to save OpenAI." To me, the drama highlighted one of the most urgent questions of our generation: How do we govern artificial intelligence? With AI on track to rewire a great many other crucial functions in society, that question is really asking: How do we ensure that we'll make our future better, not worse? The events of November 2023 illustrated in the clearest terms just how much a power struggle among a tiny handful of Silicon Valley elites is currently shaping the future of this technology. And the scorecard of this centralized approach to AI development is deeply troubling. OpenAI today has become everything that it said it would not be....
The author believes OpenAI "has grown ever more secretive, not only cutting off access to its own research but shifting norms across the industry to no longer share meaningful technical details about AI models..."

"At the same time, more and more doubts have risen about the true economic value of generative AI, including a growing body of studies that have shown that the technology is not translating into productivity gains for most workers, while it's also eroding their critical thinking."
