alternative_right shares a report from ScienceAlert: A new study adds to the growing body of evidence that swearing can help us unleash our inner strength, improving physical performance, it seems, by helping people break through certain psychological barriers. [...] [Psychology researcher Richard Stephens of Keele University in the UK] and his colleagues at Keele and the University of Alabama wanted to test whether swearing could not only improve physical performance, as they had done in previous research, but also see whether it does so by changing a person's psychology in the moment, especially when it comes to letting go of inhibitions.

Eighty-eight participants, aged 18 to 65, all in good enough shape to exert themselves physically, were recruited at a university campus to participate in the first experiment. They each selected a pair of words based on the following prompts: a swear word you might utter after bumping your head, and a neutral word you might use to describe a table. Then, they undertook a chair push-up, which involves sitting in a chair and, holding each side of the seat, using your arms to lift your entire body weight (bottom off the chair, feet off the floor). [...]

Both experiments suggested that swearing offers an advantage in physical performance, with participants achieving longer chair push-up hold times as they repeated their foul-mouthed mantras. Scores for positive emotion, humor, distraction, and novelty were also elevated in the swearing tests, which suggests invoking their favorite four-letter word might enable people to transition into more action-oriented states, and perhaps actually enjoy their workout more. The research is published in American Psychologist.

Meta has paused its third-party Horizon OS headset program, effectively canceling planned VR headsets from Asus and Lenovo as it refocuses on "building the world-class first-party hardware and software needed to advance the VR market." Road to VR reports: A little over a year and a half ago, Meta made an "industry-altering announcement," as I called the move in my reporting: the company was rebranding the Quest operating system to 'Horizon OS' and announced it was working with select partners to launch third-party VR headsets powered by the operating system. Meta specifically named Asus and Lenovo as the first partners it was working with to build new Horizon OS headsets. Asus was said to be building an "all-new performance gaming headset," while Lenovo was purportedly working on "mixed reality devices for productivity, learning, and entertainment."

But as we've now learned, neither headset is likely to see the light of day. Meta say it has frozen the third-party Horizon OS headset program. "We have paused the program to focus on building the world-class first-party hardware and software needed to advance the VR market," a Meta spokesperson told Road to VR. "We're committed to this for the long term and will revisit opportunities for 3rd-party device partnerships as the category evolves."

The traditional signals that employers used to evaluate entry-level job candidates -- college GPAs, cover letters, and interview performance -- have lost much of their value as grade inflation and widespread AI use render these metrics nearly meaningless, writes The Atlantic.

The recent-graduate unemployment rate now sits slightly higher than the overall workforce's, a reversal from historical norms where new college graduates were more likely to be employed than the average worker. Job postings on Handshake, a career-services platform for students and recent graduates, have fallen by more than 16 percent in the past year. At Harvard, 60% of undergraduate grades are now A's, up from fewer than a quarter two decades ago. Seven years ago, 70% of new graduates' resumes were screened by GPA; that figure has dropped to 40%.

Two working papers examining Freelancer.com found that cover-letter quality once strongly predicted who would get hired and how well they would perform -- until ChatGPT became available. "We basically find the collapse of this entire signaling mechanism," researcher Jesse Silbert said. The average number of applications per open job has increased by 26% in the past year. Students at UC Berkeley are now applying to 150 internships just to land one or two interviews.

Stanford researchers spent much of the past year building an AI bot called Artemis that scans networks for software vulnerabilities, and when they pitted it against ten professional penetration testers on the university's own engineering network, the bot outperformed nine of them. The experiment offers a window into how rapidly AI hacking tools have improved after years of underwhelming performance.

"We thought it would probably be below average," said Justin Lin, a Stanford cybersecurity researcher. Artemis found bugs at a fraction of human cost -- just under $60 per hour compared to the $2,000 to $2,500 per day that professional pen testers typically charge. But its performance wasn't flawless. About 18% of its bug reports were false positives, and it completely missed an obvious vulnerability on a webpage that most human testers caught. In one case, Artemis found a bug on an outdated page that didn't render in standard browsers; it used a command-line tool called Curl instead of Chrome or Firefox.

Dan Boneh, a Stanford computer science professor who advised the researchers, noted that vast amounts of software shipped without being vetted by LLMs could now be at risk. "We're in this moment of time where many actors can increase their productivity to find bugs at an extreme scale," said Jacob Klein, head of threat intelligence at Anthropic.

Wired published an article by California-based writer/programmer Sheon Han arguing that Ruby "is not a serious programming language."

Han believes that the world of programming has "moved on", and "everything Ruby does, another language now does better, leaving it without a distinct niche. Ruby is easy on the eyes. Its syntax is simple, free of semicolons or brackets. More so even thanPython — a language known for its readability — Ruby reads almost like plain English... Ruby, you might've guessed, is dynamically typed. Python and JavaScript are too, but over the years, those communities have developed sophisticated tools to make them behave more responsibly. None of Ruby's current solutions are on par with those. It's far too conducive to what programmers call "footguns," features that make it all too easy to shoot yourself in the foot.

Critically, Ruby's performance profile consistently ranks near the bottom (read: slowest) among major languages. You may remember Twitter's infamous "fail whale," the error screen with a whale lifted by birds that appeared whenever the service went down. You could say that Ruby was largely to blame. Twitter's collapse during the 2010 World Cup served as a wake-up call, and the company resolved to migrate its backend to Scala, a more robust language.

The move paid off: By the 2014 World Cup, Twitter handled a record 32 million tweets during the final match without an outage. Its new Scala-based backend could process up to 100 times faster than Ruby. In the 2010s, a wave of companies replaced much of their Ruby infrastructure, and when legacy Ruby code remained, new services were written in higher-performance languages.

You may wonderwhy people are still using Ruby in 2025. It survives because of its parasitic relationship with Ruby on Rails, the web framework that enabled Ruby's widespread adoption and continues to anchor its relevance.... Rails was the framework of choice for a new generation of startups. The main code bases of Airbnb, GitHub, Twitter, Shopify, and Stripe were built on it.
He points out on Stack Overflow's annual developer survey, Ruby has slipped from a top-10 technology in 2013 to #18 this year — "behind evenAssembly" — calling Ruby "a kind of professional comfort object, sustained by the inertia of legacy code bases and the loyalty of those who first imprinted upon it." But the article drew some criticism on X.com. ("You should do your next piece about how Vim isn't a serious editor and continue building your career around nerd sniping developers.")

Other reactions...

• "Maybe WIRED is just not a serious medium..."

• "FWIW — Ruby powered Shopify through another Black Friday / Cyber Monday — breaking last year's record."

• "Maybe you should have taken a look at TypeScript..."

Wired's subheading argues that Ruby "survives on affection, not utility. Let's move on." Are they right? Share your own thoughts and experiences in the comments.

Is Ruby still a 'serious' programming language?

sinij shares news of the Trump administration surprising the auto industry by granting approval for "tiny cars" to be built in the United States. Bloomberg reports: President Donald Trump, apparently enamored by the pint-sized Kei cars he saw during his recent trip to Japan, has paved the way for them to be made and sold in the U.S., despite concerns that they're too small and slow to be driven safely on American roads. "They're very small, they're really cute, and I said "How would that do in this country?'" Trump told reporters on Wednesday at the White House, as he outlined plans to relax stringent Biden-era fuel efficiency standards.

"But we're not allowed to make them in this country and I think you're gonna do very well with those cars, so we're gonna approve those cars," he said, adding that he's authorized Transportation Secretary Sean Duffy to approve production. [...] In response to Trump's latest order, Duffy said his department has "cleared the deck" for Toyota Motor Corp. and other carmakers to build and sell cars in the U.S. that are "smaller, more fuel-efficient." Trump's seeming embrace of Kei cars is the latest instance of passenger vehicles being used as a geopolitical bargaining chip between the U.S. and Japan. "This makes a lot of sense in urban settings, especially when electrified," comments sinij. "Hopefully these are restricted from the highway system."

The report notes that these Kei cars generally aren't allowed in the U.S. as new vehicles because they don't meet federal crash-safety and performance standards, and many states restrict or ban them due to concerns that they're too small and slow for American roads. However, they can be imported if they're over 25 years old, but then must abide by state rules that often limit them to low speeds or private property use.

AWS is deepening its partnership with Nvidia by adopting "NVLink Fusion" in its upcoming Trainium4 AI chips. "The NVLink technology creates speedy connections between different kinds of chips and is one of Nvidia's crown jewels," notes Reuters. From the report: Nvidia has been pushing to sign up other chip firms to adopt its NVLink technology, with Intel, Qualcomm and now AWS on board. The technology will help AWS build bigger AI servers that can recognize and communicate with one another faster, a critical factor in training large AI models, in which thousands of machines must be strung together. As part of the Nvidia partnership, customers will have access to what AWS is calling AI Factories, exclusive AI infrastructure inside their own data centers for greater speed and readiness.

Separately, Amazon said it is rolling out new servers based on a chip called Trainium3. The new servers, available on Tuesday, each contain 144 chips and have more than four times the computing power of AWS's previous generation of AI, while using 40% less power, Dave Brown, vice president of AWS compute and machine learning services, told Reuters. Brown did not give absolute figures on power or performance, but said AWS aims to compete with rivals -- including Nvidia -- based on price. "Together, Nvidia and AWS are creating the compute fabric for the AI industrial revolution - bringing advanced AI to every company, in every country, and accelerating the world's path to intelligence," Nvidia CEO Jensen Huang said in a statement.

An anonymous reader quotes a report from the Wall Street Journal: The Trump administration has agreed to inject up to $150 million into a startup (source paywalled; alternative source) trying to develop more advanced semiconductor manufacturing techniques in the U.S., its latest bid to support strategically important domestic industries with government incentives. Under the arrangement, the Commerce Department would give the incentives to xLight, a startup trying to improve the critical chip-making process known as extreme ultraviolet lithography, the agency said in a Monday release. In return, the government would get an equity stake that would likely make it xLight's largest shareholder.

The Dutch firm ASML is currently the only global producer of EUV machines, which can cost hundreds of millions of dollars each. XLight is seeking to improve on just one component of the EUV process: the crucially important lasers that etch complex microscopic patterns onto chemical-treated silicon wafers. The startup is hoping to integrate its light sources into ASML's machines. XLight represents a second act for Pat Gelsinger, the former chief executive of Intel who was fired by the board late last year after the chip maker suffered from weak financial performance and a stalled manufacturing expansion. Gelsinger serves as executive chairman of xLight's board.

[...] The xLight deal uses funding from the 2022 Chips and Science Act allocated for earlier stage companies with promising technologies. It is the first Chips Act award in President Trump's second term and is a preliminary agreement, meaning it isn't finalized and could change. "This partnership would back a technology that can fundamentally rewrite the limits of chipmaking," Commerce Secretary Howard Lutnick said in the release.

Digital Trends reports: A wave of shortages now threatens to ripple across RAM, SSDs, and even hard drives, affecting not only performance-hungry rigs but also everyday systems.

— CyberPowerPC has publicly confirmed it will raise prices on all systems starting December 7th due to RAM costs spiking by 500% and SSD prices doubling since October.

— Memory suppliers warn of a global DRAM and SSD shortage running into late 2026 or even 2027, driven heavily by AI server demand.

— As reported by Bloomberg, Lenovo has already stockpiled memory to ride out the crunch and maintain steadier PC pricing.

— Among other OEMs, HP, in its recent earnings call, flagged possible price increases or lower-spec models on the back of rising component costs.
But Apple "may also be in a good position to weather the shortage," reports Ars Technica, since "analysts at Morgan Stanley and Bernstein Research believe that Apple has already laid claim to the RAM that it needs and that its healthy profit margins will allow it to absorb the increases better than most."

Ars Technica also shows how much RAM and storage prices have jumped — sometimes as much as 2x or even 3x in just three months. "In short, there's no escaping these price increases, which affect SSDs and both DDR4 and DDR5 RAM kits of all capacities (though higher-capacity RAM kits do seem to be hit a little harder)." Memory and storage shortages can be particularly difficult to get through. As with all chips, it can take years to ramp up capacity and/or build new manufacturing facilities... And memory makers in particular may be slow to ramp up manufacturing capacity in response to shortages. If they decide to start manufacturing more chips now, what happens if memory demand drops off a cliff in six months or a year (if, say, an AI bubble deflates or pops altogether)? It means an oversupply of memory chips — consumers benefit from rock-bottom prices for components, but it becomes harder for manufacturers to cover their costs... The upshot is: Not only are memory prices getting bad now, but it's exceptionally difficult to predict when shortage-fueled price hikes might end...

Tom's Hardware reports that AMD has told its partners that it expects to raise GPU prices by about 10 percent starting next year and that Nvidia may have canceled a planned RTX 50-series Super launch entirely because of shortages and price increases.

Nvidia pushed back against investor concerns about Google's competitive positioning in AI on Tuesday after the chipmaker's shares tumbled 4.4% and erased nearly $200 billion in market cap on fears that Alphabet's tensor processing units were gaining ground against its dominance in AI computing. The company said it was "delighted by Google's success" but asserted that it continues to supply chips to Google.

Nvidia said it remains "a generation ahead of the industry" as the only platform that runs every AI model and operates everywhere computing is done. The statement came after investors reacted to the release of Google's Gemini 3 large language model last week. The model was trained using TPUs rather than Nvidia chips. A report in The Information on Monday said Google was pitching potential clients including Meta on using TPUs in their data centers rather than Nvidia's chips.

Nvidia said its platform offers "greater performance, versatility, and fungibility than ASICs," referring to application-specific integrated circuits like Google's TPUs that are designed for specific AI frameworks or functions. Google's TPUs have until now only been available for customers to rent through its cloud computing service. Nvidia has lost more than $800 billion in market value since it peaked above $5 trillion less than a month ago.

The abstract of a paper on NBER: This paper examines a large-scale randomized evaluation of the One Laptop Per Child (OLPC) program in 531 Peruvian rural primary schools. We use administrative data on academic performance and grade progression over 10 years to estimate the long-run effects of increased computer access on (i) school performance over time and (ii) students' educational trajectories. Following schools over time, we find no significant effects on academic performance but some evidence of negative effects on grade progression. Following students over time, we find no significant effects on primary and secondary completion, academic performance in secondary school, or university enrollment. Survey data indicate that computer access significantly improved students' computer skills but not their cognitive skills; treated teachers received some training but did not improve their digital skills and showed limited use of technology in classrooms, suggesting the need for additional pedagogical support.

In the latest Windows Insider beta update, Microsoft has announced that it is exploring preloading File Explorer in the background to improve launch performance. The feature will load File Explorer silently before users click on it and can be toggled off for those who prefer not to use it. Microsoft introduced a similar capability earlier this year for Office called Startup Boost that loads parts of Word in the background so the application launches more quickly. The company is also removing elements from the File Explorer context menu in the same update.

Amazon is committing up to $50 billion to massively expand AI and supercomputing capacity for U.S. government cloud regions, adding 1.3 gigawatts of high-performance compute and giving federal agencies access to its full suite of AI tools. Reuters reports: The project, expected to break ground in 2026, will add nearly 1.3 gigawatts of artificial intelligence and high-performance computing capacity across AWS Top Secret, AWS Secret and AWS GovCloud regions by building data centers equipped with advanced compute and networking technologies. The project, expected to break ground in 2026, will add nearly 1.3 gigawatts of artificial intelligence and high-performance computing capacity across AWS Top Secret, AWS Secret and AWS GovCloud regions by building data centers equipped with advanced compute and networking technologies.

Under the latest initiative, federal agencies will gain access to AWS' comprehensive suite of AI services, including Amazon SageMaker for model training and customization, Amazon Bedrock for deploying models and agents, as well as foundation models such as Amazon Nova and Anthropic Claude. The federal government seeks to develop tailored AI solutions and drive cost-savings by leveraging AWS' dedicated and expanded capacity.

Apple's next major iPhone software update will prioritize stability and performance over flashy new features, according to Bloomberg's Mark Gurman, who reports that iOS 27 is being developed as a "Snow Leopard-style" release [non-paywalled source] focused on fixing bugs, removing bloat and improving underlying code after this year's sweeping Liquid Glass design overhaul in iOS 26.

Engineering teams are currently combing through Apple's operating systems to eliminate unnecessary code and address quality issues that users have reported since iOS 26's September release. Those complaints include device overheating, unexplained battery drain, user interface glitches, keyboard failures, cellular connectivity problems, app crashes, and sluggish animations.

iOS 27 won't be feature-free. Apple plans several AI additions: a health-focused AI agent tied to a Health+ subscription, expanded AI-powered web search meant to compete with ChatGPT and Perplexity, and deeper AI integration across apps. The company has also been internally testing a chatbot app called Veritas as a proving ground for its re-architected Siri, though a standalone chatbot product isn't currently planned.

"Copilot Actions on Windows 11" is currently available in Insider builds (version 26220.7262) as part of Copilot Labs, according to a recent report, "and is off by default, requiring admin access to set it up."

But maybe it's off for a good reason...besides the fact that it can access any apps installed on your system: In a support document, Microsoft admits that features like Copilot Actions introduce "\novel security risks ." They warn about cross-prompt injection (XPIA), where malicious content in documents or UI elements can override the AI's instructions. The result? " Unintended actions like data exfiltration or malware installation ."

Yeah, you read that right. Microsoft is shipping a feature that could be tricked into installing malware on your system. Microsoft's own warning hits hard: "We recommend that you only enable this feature if you understand the security implications." When you try to enable these experimental features, Windows shows you a warning dialog that you have to acknowledge. ["This feature is still being tested and may impact the performance or security of your device."]

Even with these warnings, the level of access Copilot Actions demands is concerning. When you enable the feature, it gets read and write access to your Documents, Downloads, Desktop, Pictures, Videos, and Music folders... Microsoft says they are implementing safeguards. All actions are logged, users must approve data access requests, the feature operates in isolated workspaces, and the system uses audit logs to track activity.

But you are still giving an AI system that can "hallucinate and produce unexpected outputs" (Microsoft's words, not mine) full access to your personal files.
To address this, Ars Technica notes, Microsoft added this helpful warning to its support document this week. "As these capabilities are introduced, AI models still face functional limitations in terms of how they behave and occasionally may hallucinate and produce unexpected outputs."

But Microsoft didn't describe "what actions they should take to prevent their devices from being compromised. I asked Microsoft to provide these details, and the company declined..."

A week ago Bitcoin was at $93,714. Saturday it dropped to $85,300.

Late Thursday, market researcher Ed Yardeni blamed some of Thursday's stock market sell-off on "the ongoing plunge in bitcoin's price," reports Fortune: "There has been a strong correlation between it and the price of TQQQ, an ETF that seeks to achieve daily investment results that correspond to three times (3x) the daily performance of the Nasdaq-100 Index," [Yardeni wrote in a note]. Yardeni blamed bitcoin's slide on the GENIUS Act, which was enacted on July 18, saying that the regulatory framework it established for stablecoins eliminated bitcoin's transactional role in the monetary system. "It's possible that the rout in bitcoin is forcing some investors to sell stocks that they own," he added... Traders who used leverage to make crypto bets would need to liquidate positions in the event of margin calls.

Steve Sosnick, chief strategist at Interactive Brokers, also said bitcoin could swing the entire stock market, pointing out that it's become a proxy for speculation. "As a long-time systematic trader, it tells me that algorithms are acting upon the relationship between stocks and bitcoin," he wrote in a note on Thursday.

ScienceDaily reports: Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre "pinball" state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for advanced quantum technologies...

When electrons settle into these rigid arrangements, the material undergoes a shift in its state of matter and stops conducting electricity. Instead of acting like a metal, it behaves as an insulator. This unusual behavior provides scientists with valuable insight into how electrons interact and has opened the door to advances in quantum computing, high-performance superconductors used in energy and medical imaging, innovative lighting systems, and extremely precise atomic clocks... [Florida State University assistant professor Cyprian Lewandowski said] "Here, it turns out there are other quantum knobs we can play with to manipulate states of matter, which can lead to impressive advances in experimental research."

An anonymous reader quotes a report from Ars Technica: Some Dell and HP laptop owners have been befuddled by their machines' inability to play HEVC/H.265 content in web browsers, despite their machines' processors having integrated decoding support. Laptops with sixth-generation Intel Core and later processors have built-in hardware support for HEVC decoding and encoding. AMD has made laptop chips supporting the codec since 2015. However, both Dell and HP have disabled this feature on some of their popular business notebooks.

HP discloses this in the data sheets for its affected laptops, which include the HP ProBook 460 G11 [PDF], ProBook 465 G11 [PDF], and EliteBook 665 G11 [PDF]. "Hardware acceleration for CODEC H.265/HEVC (High Efficiency Video Coding) is disabled on this platform," the note reads. Despite this notice, it can still be jarring to see a modern laptop's web browser eternally load videos that play easily in media players. HP and Dell didn't explain why the companies disabled HEVC hardware decoding on their laptops' processors.

A statement from an HP spokesperson said: "In 2024, HP disabled the HEVC (H.265) codec hardware on select devices, including the 600 Series G11, 400 Series G11, and 200 Series G9 products. Customers requiring the ability to encode or decode HEVC content on one of the impacted models can utilize licensed third-party software solutions that include HEVC support. Check with your preferred video player for HEVC software support."

Dell's media relations team shared a similar statement: "HEVC video playback is available on Dell's premium systems and in select standard models equipped with hardware or software, such as integrated 4K displays, discrete graphics cards, Dolby Vision, or Cyberlink BluRay software. On other standard and base systems, HEVC playback is not included, but users can access HEVC content by purchasing an affordable third-party app from the Microsoft Store. For the best experience with high-resolution content, customers are encouraged to select systems designed for 4K or high-performance needs."

An anonymous reader quotes a report from Ars Technica: This year's newest iPhones included one momentous change that marked a new phase in the evolution of Apple Silicon: the Apple N1, Apple's first in-house chip made to handle local wireless connections. The N1 supports Wi-Fi 7, Bluetooth 6, and the Thread smart home communication protocol, and it replaces the third-party wireless chips (mostly made by Broadcom) that Apple used in older iPhones. Apple claimed that the N1 would enable more reliable connectivity for local communication features like AirPlay and AirDrop but didn't say anything about how users could expect it to perform. But Ookla, the folks behind the SpeedTest app and website, have analyzed about five weeks' worth of users' testing data to get an idea of how the iPhone 17 lineup stacks up to the iPhone 16, as well as Android phones with Wi-Fi chips from Qualcomm, MediaTek, and others.

While the N1 isn't at the top of the charts, Ookla says Apple's Wi-Fi chip "delivered higher download and upload speeds on Wi-Fi compared to the iPhone 16 across every studied percentile and virtually every region." The median download speed for the iPhone 17 series was 329.56Mbps, compared to 236.46Mbps for the iPhone 16; the upload speed also jumped from 73.68Mbps to 103.26Mbps. Ookla noted that the N1's best performance seemed to improve scores most of all in the bottom 10th percentile of performance tests, "implying Apple's custom silicon lifts the floor more than the ceiling." The iPhone 17 also didn't top Ookla's global performance charts -- Ookla found that the Pixel 10 Pro series slightly edges out the iPhone 17 in download speed, while a Xiaomi 15T Pro with MediaTek Wi-Fi silicon featured better upload speeds.

pbahra writes: Saudi Arabia is betting that the future of Hollywood won't be built in physical stages but in datacenters. In a push to anchor itself in next-generation film production, Riyadh-based Humain has led Luma AI's latest Series C round, backing the shift towards cloud-based, AI-generated video rather than traditional studio infrastructure.. Humain's announcement says the new investment will accelerate Luma's development of world models capable of learning from video, audio and language to generate photorealistic scenes, environments and characters on demand. Supporters argue this could upend film-making by pushing much of Hollywood's production pipeline into high-performance datacenters rather than physical sets.
