At CES 2025, AMD unveiled the Z2, Z2 Go, and Z2 Extreme chipsets -- all powered by Zen 5 CPU cores and designed for handheld gaming PCs. IGN reports: The AMD Zen 2 Extreme, along with lower-specced cousins the Z2 and Z2 Go, are powered by Zen 5 CPU cores. While the Zen 2 Extreme is using a RDNA 3.5-based GPU, the Z2 and Z2 Go are still using RDNA 3 and RDNA 2, respectively. This creates an entire family of APUs (Advanced Processing Units) for handheld gaming PCs that should hopefully cause the price of handhelds to go down a bit. With the Z2 Extreme, AMD is hoping to dramatically improve battery life, while also delivering console-like gaming performance to devices like the Lenovo Legion Go. By and large, the biggest limiting factor of these handhelds, especially at the high end, is how quickly their batteries drain when playing demanding games away from a wall outlet. The company also introduced the "Fire Range" HX3D processors for gaming laptops, leveraging 3D V-cache technology for enhanced gaming performance and efficiency. "All of these mobile chipsets, from 'Fire Range' HX3D to the AMD Z2 Extreme, will end up in gaming laptops and handhelds over the next few months," adds IGN. AMD published a press release with additional details and specifications.

An anonymous reader quotes a report from Reuters: The U.S. Defense Department said on Monday it has added Chinese tech giants including gaming and social media leader Tencent Holdings and battery maker CATL to a list of firms it says work with China's military. The list also included chip maker Changxin Memory Technologies, Quectel Wireless and drone maker Autel Robotics, according to a document published on Monday. The annually updated list (PDF) of Chinese military companies, formally mandated under U.S. law as the "Section 1260H list," designated 134 companies, according to a notice posted to the Federal Register. U.S.-traded shares of Tencent, which is also the parent of Chinese instant messaging app WeChat, fell 8% in over-the-counter trading. Tencent said in a statement that its inclusion on the list was "clearly a mistake." It added: "We are not a military company or supplier. Unlike sanctions or export controls, this listing has no impact on our business." CATL called the designation a mistake, saying it "is not engaged in any military related activities." A Quectel spokesperson said the company "does not work with the military in any country and will ask the Pentagon to reconsider its designation, which clearly has been made in error." While the designation does not involve immediate bans, it can be a blow to the reputations of affected companies and represents a stark warning to U.S. entities and firms about the risks of conducting business with them. It could also add pressure on the Treasury Department to sanction the companies. Two previously listed companies, drone maker DJI and Lidar-maker Hesai Technologies, both sued the Pentagon last year over their previous designations, but remain on the updated list. The Pentagon also removed six companies it said no longer met the requirements for the designation, including AI firm Beijing Megvii Technology, China Railway Construction Corporation Limited, China State Construction Group Co and China Telecommunications Corporation.

Toyota's Woven City, a $10 billion "living laboratory" on the site of a former car factory, is set to welcome its first 100 residents in fall 2025. The first residents will be Toyota employees and affiliates, but the city aims to expand to include "external inventors and their families." The Verge reports: Toyota said it completed "phase 1" of the construction, with the official launch planned for 2025. "Woven City is more than just a place to live, work, and play," Toyota Chairman Akio Toyoda said during today's press conference at CES. "Woven City is a place where people can invent and develop all kinds of new products and ideas. It's a living laboratory where the residents are willing participants, giving inventors the opportunity to freely test their ideas in a secure, real-life setting." [...] In fall 2025, Toyota said it will welcome the first 100 residents to Woven City, all of whom will be employees of Toyota or its subsidiary, Woven by Toyota. The community will gradually expand to include "external inventors and their families" who will be invited to relocate to the new city. In total, the first phase of the city will eventually house 360 residents, Toyota says. Toyota dubs these first residents "Weavers," adding that they are people who "share a passion for the 'expansion of mobility' and a commitment to building a more flourishing society. Through their participation in co-creation activities, Weavers will contribute to realizing the full potential of Woven City." That said, the first "inventors" confirmed for Woven City are mostly in the food services business, including a vending machine company and a startup that wants to explore "the potential value of coffee through futuristic cafe experiences." Toyoda mentioned several other ideas during his press conference, including high-powered motorized wheelchairs for people with disabilities who want to experience the thrill of racing. He also pitched the idea of a personal drone that follows joggers for added security, and "pet robots" for elderly people. The Woven City site, which is located at the base of Mount Fuji, includes buildings that are designed by famed Danish architect Bjarke Ingels. The goal, through phase 2 and subsequent phases, is to build enough housing and facilities for up to 2,000 people to live year-around, with utilities powered by the company's hydrogen fuel cell technology. The site is private for now, though Toyota says it plans on inviting the general public to see it in 2026. The name "Woven City" is a reference to weaving together three different types of streets or pathways, each for a specific type of user. One street would be for faster vehicles only. The second would be a mix of lower-speed personal mobility vehicles, like bikes and scooters, as well as pedestrians. And the third would be a park-like promenade for pedestrians only. Japan first announced the "prototype city of the future" at CES 2020.

A forthcoming peer-reviewed study (PDF) from Rutgers University's Network Contagion Research Institute argues that TikTok surfaces fewer anti-CCP posts compared to Instagram and YouTube, despite higher user engagement with such content. It also found that heavy TikTok usage correlates with more favorable views of China's human rights record. The findings come a Supreme Court hearing later this week on whether the federal government can ban TikTok. Gizmodo reports: The new peer-reviewed paper, which was first reported by The Free Press, begins by examining whether content on TikTok, Instagram, and YouTube related to the keywords "Tiananmen," "Tibet," "Uyghur," and "Xinjiang" tends to display pro- or anti-CCP sentiment. The researchers found that TikTok's algorithm didn't necessarily surface more pro-CCP content in response to searches for those terms, but it delivered fewer anti-CCP posts than did Instagram or YouTube and significantly more posts that were irrelevant to the subject. In the second stage of their study, the NCRI team tested whether the lower performance of anti-CCP content was a result of less user engagement (likes and comments) with those posts. They found that TikTok users "liked or commented on anti-CCP content nearly four times as much as they liked or commented on pro-CCP content, yet the search algorithm produced nearly three times as much pro-CCP content" while there was no similar discrepancy on Instagram or YouTube. Finally, the researchers surveyed 1,214 Americans about their social media usage and their views on China's human rights record. The more time users spent on any social media platform, the more likely they were to have favorable views of China's human rights record, the survey showed. Users were particularly more likely to have favorable views if they spent more than three hours a day using TikTok. The researchers wrote that they could not definitively conclude that spending more time on TikTok resulted in more positive views of China, but "taken together, the findings from these three studies raise the distinct possibility that TikTok is a vehicle for CCP propaganda."

An anonymous reader quotes a report from Ars Technica: After ditching the traditional Dell XPS laptop look in favor of the polarizing design of the XPS 13 Plus released in 2022, Dell is killing the XPS branding that has become a mainstay for people seeking a sleek, respectable, well-priced PC. This means that there won't be any more Dell XPS clamshell ultralight laptops, 2-in-1 laptops, or desktops. Dell is also killing its Latitude, Inspiron, and Precision branding, it announced today. Moving forward, Dell computers will have either just Dell branding, which Dell's announcement today described as "designed for play, school, and work," Dell Pro branding "for professional-grade productivity," or be Dell Pro Max products, which are "designed for maximum performance." Dell will release Dell and Dell Pro-branded displays, accessories, and "services," it said. The Pro Max line will feature laptops and desktop workstations with professional-grade GPU capabilities as well as a new thermal design. Dell claims its mid-tier Pro line emphasizes durability, "withstanding three times as many hinge cycles, drops, and bumps from regular use as competitor devices." The statement is based on "internal analysis of multiple durability tests performed" on the Dell Pro 14 Plus (released today) and HP EliteBook 640 G11 laptops conducted in November. Also based on internal testing conducted in November, Dell claims its Pro PCs boost "airflow by 20 percent, making these Dell's quietest commercial laptops ever." Within each line are base models, Plus models, and Premium models. In a blog post, Kevin Terwilliger, VP and GM of commercial, consumer, and gaming PCs at Dell, explained that Plus models offer "the most scalable performance" and Premium models offer "the ultimate in mobility and design." By those naming conventions, old-time Dell users could roughly equate XPS laptops with new Dell Premium products. [...] Dell will maintain its Alienware line of gaming PCs and peripherals (Dell acquired Alienware in 2006). The changes were made to create more "unified branding" that will make it "easier and faster to find the right PCs, accessories, and services," said Dell in a press release. It also serves to push the company's "AI PCs" onto consumers. Dell notes that it will maintain its Alienware line of gaming PCs and peripherals "that's been service PC gamers for nearly 30 years."

Computer scientists are using hypothetical devices called "oracles" to advance the field of computational complexity theory, exploring fundamental questions about problem-solving difficulty. These theoretical tools, which instantly provide correct yes-or-no answers to specific questions, help researchers understand relationships between different classes of computational problems. Oracles have proved particularly valuable in studying quantum computing, leading to breakthroughs like Peter Shor's 1994 quantum algorithm for factoring large numbers. The technique has also helped researchers rule out certain approaches to solving the longstanding P versus NP problem, a central question in computer science.

Intel, which has been fending off mounting competition in notebook processors, says a new range of chips will help enable the longest battery life available in laptops. From a report: New computers based on the latest version of its Core Ultra processors will go on sale starting this month, the company said Monday at CES, an annual consumer electronics show. Intel was for decades the world's largest chipmaker thanks to its dominance of the computer processor market. Production technology stumbles and slow product introductions have opened the door to both long-time rivals and firms just entering the space. The company's board last month ousted its chief executive officer, citing the need to improve its offerings. The new chips, intended for corporate PCs and high-end consumer devices, are aimed at boosting performance in two areas the company considers key selling points: battery life and the ability to run artificial intelligence functions. According to Intel, an HP laptop that uses one of the new processors can run Microsoft's Teams software for as long as 10.5 hours on a single charge. It can go 20.3 hours between charges when the user is running Microsoft's cloud-based 365 suite, Intel added. By comparison, Intel says a Dell device using a Qualcomm Snapdragon processor can last as long as 9.2 hours and 18.5 hours, respectively, under those conditions.

More than 1.6 million Americans have been jobless for at least six months, up 50% since late 2022, despite the economy adding over two million jobs last year, Labor Department data shows. The average job search now takes six months, primarily affecting high-paying sectors like tech, law, and media. While the 4.2% unemployment rate remains below pre-pandemic averages, job postings have dropped to one per unemployed worker from two in early 2022. Software development, data science, and marketing roles are 20% below pre-pandemic levels, while healthcare and government sectors account for half of recent job creation. The number of Americans receiving unemployment benefits reached 1.8 million in late December, approaching post-pandemic highs, as wage growth declined to 4% from 6% during the early 2020s hiring peak.

The climate crisis is "wreaking havoc" on the planet's water cycle, with ferocious floods and crippling droughts affecting billions of people, a report has found. The Guardian: Water is people's most vital natural resource but global heating is changing the way water moves around the Earth. The analysis of water disasters in 2024, which was the hottest year on record, found they had killed at least 8,700 people, driven 40 million from their homes and caused economic damage of more than $550bn. Rising temperatures, caused by continued burning of fossil fuels, disrupt the water cycle in multiple ways. Warmer air can hold more water vapour, leading to more intense downpours. Warmer seas provide more energy to hurricanes and typhoons, supercharging their destructive power. Global heating can also increase drought by causing more evaporation from soil, as well as shifting rainfall patterns. Deadly flash floods hit Nepal and Brazil in 2024, while river flooding caused devastation in central Europe, China and Bangladesh. Super Typhoon Yagi, which struck south-east Asia in September, was intensified by the climate crisis, as was Storm Boris which hit Europe the same month. Droughts also caused major damage, with crop production in southern Africa halving, causing more than 30 million people to face food shortages. Farmers were also forced to cull livestock as their pastures dried up, and falling output from hydropower dams led to widespread blackouts.

The Walt Disney Co. will merge its streaming multichannel video service Hulu with Live TV with its competitor Fubo in a surprise deal that will shake up the streaming TV business, the companies said Monday. From a report: The new company will continue to be traded publicly under the Fubo name, however Disney will control 70% and appoint a majority of the board. Fubo management, including co-founder and CEO David Gandler, will run the combined venture. The deal will do a couple of big things if and when it is completed: For starters, it will create a much bigger player in the virtual multichannel video provider (vMVPD) space, one that can more aggressively take on the market leader YouTube TV. YouTube TV said a year ago that it had 8 million subscribers, while Hulu + Live TV had 4.6 million subscribers and Fubo had 1.6 million subscribers, giving a combined offering 6.2 million subs.

"Millions of computers are heading towards a security crisis as Microsoft plans to end support for Windows 10 on October 14, 2025," writes BetaNews: 32 million devices — roughly 65 percent of household computers in Germany — are still running the aging operating system. In the DACH region, including Austria and Switzerland, over 35 million systems rely on Windows 10, leaving millions of users exposed to potential cyberattacks once updates stop. By contrast, only about 33 percent of German devices have transitioned to Windows 11, and over a million are still running even older systems like Windows 8, 7, or XP. Thorsten Urbanski, an IT security expert at ESET, is sounding the alarm. "It's five minutes to midnight to prevent a security fiasco in 2025. We strongly urge users not to wait until October. Upgrade to Windows 11 now or choose an alternative operating system if your device cannot support the latest version. Otherwise, users are exposing themselves to significant security risks, including dangerous cyberattacks and data breaches...." Urbanski also points out that the current situation is worse than when Windows 7 support ended in 2020. By late 2019, over 70 percent of users had already switched to Windows 10, while only about 20 percent remained on Windows 7. Today, the transition to Windows 11 is far slower, creating a dangerous environment. "Cybercriminals know these numbers well and are waiting for the end-of-support date. Once that hits, vulnerabilities will be exploited en masse." "Those unable to move to Windows 11 are being advised to consider Linux as a secure alternative, especially for older hardware." Thanks to Slashdot reader BrianFagioli for sharing the news.

As America begins a six-day state funeral for former president Jimmy Carter, Microsoft co-founder/philanthropist Bill Gates shared "my fondest memory" this week. "He and Rosalynn were among my first and most inspiring role models in global health." They played a pretty profound role in the early days of the Gates Foundation. I'm especially grateful that they introduced us to Dr. Bill Foege, who once helped eradicate smallpox and was a key advisor for our global health work. Jimmy and Rosalynn were also good friends to my dad. One of my favorite photographs of all time shows Jimmy Carter, Nelson Mandela, and my dad in South Africa holding babies at a medical clinic. I remember my dad coming back from that trip with a whole new appreciation for Jimmy's passion for helping people with HIV. At the time, then-President Thabo Mbeki was refusing to let people with HIV get treatment, and my dad watched Jimmy almost get into a fist fight with Mbeki over the issue. As Jimmy said in a 2012 conversation at the Gates Foundation hosted by my dad, "He was claiming there was no relationship between HIV and AIDS and that the medicines that we were sending in, the antiretroviral medicines, were a white person's plot to help kill black babies." At a time when a quarter of all people in South Africa were HIV positive, Jimmy just couldn't accept Mbeki's obstructionism. Ars Technica reported it was also Jimmy Carter who saved America's space shuttle program. And Carter installed solar panels on the roof of the White House (which "were later removed by his successor, Ronald Reagan," according to Boiling Point, an environmental newsletter from the Los Angeles Times: He tried and largely failed to block construction of more than a dozen expensive, environmentally destructive water infrastructure projects such as dams, canals and reservoirs. He also tried to reduce U.S. dependence on foreign oil, implementing the first vehicle fuel-efficiency standards and tasking researchers with bringing down the cost of solar panels — an effort he predicted could be "a small part of one of the greatest and most exciting adventures ever undertaken by the American people...." And although he was largely thinking about how to free Americans from geopolitical crises that could wreak havoc on oil supplies and gasoline prices, he also had heat-trapping greenhouse gases in mind... The final report from the White House Council on Environmental Quality warned that fossil fuel combustion could cause "widespread and pervasive changes in global climatic, economic, social, and agricultural patterns." It advised that to avoid such risks, we should limit global temperature increases to 2 degrees Celsius above preindustrial levels — the goal eventually agreed to by nearly 200 nations, 35 years later. Even if Carter's actions were targeted more at reducing oil imports than at cutting planet-warming pollution — he was willing to increase domestic coal production if it meant less dependence on foreign crude — the political battles he fought, particularly those he lost, have lessons for those of us who care about the climate today. The historian Kai Bird, for instance, notes that after struggling to pass a tax on gas-guzzling cars, Carter wrote in his diary, "The influence of the oil and gas industry is unbelievable, and it's impossible to arouse the public to protect themselves." Indeed, oil and gas companies still wield huge influence. SUVs are more popular than ever. The newsletter argues the story of Carter's life can be an inspiration, since Carter saw a lot of changes in his 100 years. "We need to see more changes to survive. May we all be as lucky as Carter was."

Ted's company hired a contract team to build an application. The budget eventually ran out without a finished application, so the code the contract team had produced was handed off to Ted's team to finish.

This is an example of the Ruby code Ted inherited:

def self.is_uniqueness(mr_number) out = false mrn = PatientMrn.find_by_mr_number(mr_number) if mrn out = true return mrn end return nil end

The function is called is_uniqueness which is definitely some language barrier naming (is_unique is a more English way of wording it). But if we trace through the logic, this is just a wrapper around PatientMrn.find_by_mr_number- it returns an "mrn".

So, the first obvious problem: this isn't checking uniqueness in any way, shape or form.

Then there's the whole check for a valid record- either we find a record or we return nil. But since find_by_mr_number is clearly returning something falsy, that doesn't seem necessary.

And that is the default behavior for the Rails generated find_by methods- they just return nil if there are no records. So none of the checks are needed here. This whole method isn't needed here.

Finally, there's out. I have no idea what they were trying to accomplish here, but it smells like they wanted a global variable that they could check after the call for error statuses. If that was their goal, they failed in a few ways- first, returning nil conveys the same information. Second, global variables in Ruby get a $ sigil in front of them.

What the out variable truly represents is "do I want out of this codebase?" True. That is definitely true.

This week New York Times technology columnist Kevin Roose published his annual "Good Tech" awards to "shine the spotlight on a few tech projects that I think contributed positively to humanity." And high on the list is "Andres Freund, and every open-source software maintainer saving us from doom." The most fun column I wrote this past year was about a Microsoft database engineer, Andres Freund, who got some odd errors while doing routine maintenance on an obscure open-source software package called xz Utils. While investigating, Freund inadvertently discovered a huge security vulnerability in the Linux operating system, which could have allowed a hacker to take control of hundreds of millions of computers and bring the world to its knees. It turns out that much of our digital infrastructure rests on similar acts of nerdy heroism. After writing about Freund's discovery, I received tips about other near disasters involving open-source software projects, many of which were averted by sharp-eyed volunteers catching bugs and fixing critical code just in time to foil the bad guys. I could not write about them all, but this award is to say: I see you, open-source maintainers, and I thank you for your service. Roose also acknowledges the NASA engineers who kept Voyager 1 transmitting back to earth from interstellar space — and Bluesky, "for making my social media feeds interesting again." Roose also notes it was a big year for AI. There's a shout-out to Epoch AI, a small nonprofit research group in Spain, "for giving us reliable data on the AI boom." ("The firm maintains public databases of AI models and AI hardware, and publishes research on AI trends, including an influential report last year about whether AI models can continue to grow at their current pace. Epoch AI concluded they most likely could until 2030.") And there's also a shout-out to groups "pushing AI forward" and positive uses "to improve health care, identify new drugs and treatments for debilitating diseases and accelerate important scientific research." The nonprofit Arc Institute released Evo, an AI model that "can predict and generate genomic sequences, using technology similar to the kind that allows systems like ChatGPT to predict the next words in a sequence." A Harvard University lab led by Dr. Jeffrey Lichtman teamed with researchers from Google for "the most detailed map of a human brain sample ever created. The team used AI to map more than 150 million synapses in a tiny sample of brain tissue at nanometer-level resolution..." Researchers at Stanford and McMaster universities developed SyntheMol, "a generative AI model that can design new antibiotics from scratch."
