Walmart is Ditching ZIP Codes in Favor of Honeycomb-Style Maps As It Looks To Speed Up Deliveries
Walmart is taking a lesson from the humble honeybee in its quest to make its deliveries as fast as possible. From a report: The retail giant already boasts a formidable store count of 4,700 locations across the US, which puts it within a short drive of more than 90% of households. But in order to grow its reach without necessarily having to build new supercenters, Walmart says it has been using a relatively new hexagonal map segmentation -- a change from the conventional ZIP code or radius-based strategies that are commonly used in determining delivery areas.
Walmart says the strategy allows it to better understand where customers are and which stores have what they want. As bees have long known, hexagons can be an excellent shape for making the most of a given space, and Walmart says the more precise maps allow it to reach an additional 12 million US households with same-day delivery.
"This is helping us to adapt how we service our customers, by allowing us to go from a fixed-mile radius into a much more dynamic catchment area that caters to the needs of the customers that a particular store will serve," Walmart global tech senior director of engineering Parthibban Raja told Fast Company in December, following a pilot of the concept. Walmart says its platform uses a combination of its own data and open-source software to create new delivery zones.

At Trial, Instagram Co-founder Says Zuckerberg Withheld Resources Over 'Threat' Fears
An anonymous reader shares a report: Kevin Systrom, the co-founder of Instagram, testified on Tuesday in a landmark federal antitrust trial that he left Meta in 2018 because his company was denied resources. The government has argued that Meta purchased Instagram in 2012 as part of a "buy-or-bury strategy" to illegally cement its social media monopoly by killing off its rivals. Last week, current and former Meta executives testified that the social media giant, formerly known as Facebook, used its deep pockets to invest in Instagram after its purchase.
In testimony at the U.S. District Court of the District of Columbia, Mr. Systrom painted a different picture, saying he left Meta because Mark Zuckerberg, the chief executive, wasn't investing enough. At that time, Instagram had grown to 1 billion users, about 40 percent of Facebook's size, yet the photo-sharing app had only 1,000 employees compared to 35,000 employees at Facebook, he said. "We were by far the fastest growing team. We produced the most revenue and relative to what we should have been at the time, I felt like we should have been much larger," said Mr. Systrom, who is expected to testify for six hours.
Mr. Systrom said he found the decisions baffling. When asked by an F.T.C. lawyer why Mr. Zuckerberg might have decided to give Instagram fewer resources, Mr. Systrom said it was a consistent pattern during his tenure at Meta. "Mark was not investing in Instagram because he believed we were a threat to their growth," he said, referring to Mr. Zuckerberg's prioritization of Facebook.

AI Floods Amazon With Strange Political Books Before Canadian Election
An anonymous reader shares a report: Canada has seen a boom in political books created with generative artificial intelligence, adding to concerns about how new technologies are affecting the information voters receive during the election campaign.
Prime Minister Mark Carney was the subject of at least 16 books published in March and listed on Amazon.com, according to a review of the site on April 16. Five of those were published on a single day. In total, some 30 titles were published about Carney this year and made available on Amazon -- but most were taken down from the site after inquiries from Bloomberg News.
One author, James A. Powell, put his name to at least three books about the former central banker, who's now leading the Liberal Party and is narrowly favored to win the election. Among the titles that Amazon removed: "Carney's Code: Climate Capitalism, Digital Currencies, and the Technocratic Takeover of the Global Economy -- Inside Mark Carney's Blueprint for the Post-Democratic World."

The Quest To Build Islands With Ocean Currents In the Maldives
An anonymous reader quotes a report from MIT Technology Review: Arete Glacier Initiative has raised $5 million to improve forecasts of sea-level rise and explore the possibility of refreezing glaciers in place.
Off one atoll, just south of the Maldives' capital, Male, researchers are testing one way to capture sand in strategic locations -- to grow islands, rebuild beaches, and protect coastal communities from sea-level rise. Swim 10 minutes out into the En'boodhoofinolhu Lagoon and you'll find the Ramp Ring, an unusual structure made up of six tough-skinned geotextile bladders. These submerged bags, part of a recent effort called the Growing Islands project, form a pair of parentheses separated by 90meters (around 300 feet). The bags, each about two meters tall, were deployed in December 2024, and by February, underwater images showed that sand had climbed about a meter and a half up the surface of each one, demonstrating how passive structures can quickly replenish beaches and, in time, build a solid foundation for new land. "There's just a ton of sand in there. It's really looking good," says Skylar Tibbits, an architect and founder of the MIT Self-Assembly Lab, which is developing the project in partnership with the Male-based climate tech company Invena.
The Self-Assembly Lab designs material technologies that can be programmed to transform or "self-assemble" in the air or underwater, exploiting natural forces like gravity, wind, waves, and sunlight. Its creations include sheets of wood fiber that form into three-dimensional structures when splashed with water, which the researchers hope could be used for tool-free flat-pack furniture.Growing Islands is their largest-scale undertaking yet. Since 2017, the project has deployed 10 experiments in the Maldives, testing different materials, locations, and strategies, including inflatable structures and mesh nets. The Ramp Ring is many times larger than previous deployments and aims to overcome their biggest limitation.
In the Maldives, the direction of the currents changes with the seasons. Past experiments have been able to capture only one seasonal flow, meaning they lie dormant for months of the year. By contrast, the Ramp Ring is "omnidirectional," capturing sand year-round. "It's basically a big ring, a big loop, and no matter which monsoon season and which wave direction, it accumulates sand in the same area," Tibbits says. The approach points to a more sustainable way to protect the archipelago, whose growing population is supported by an economy that caters to 2 million annual tourists drawn by its white beaches and teeming coral reefs. Most of the country's 187 inhabited islands have already had some form of human intervention to reclaim land or defend against erosion, such as concrete blocks, jetties, and breakwaters.

Google Faces Off With US Government in Attempt To Break Up Company in Search Monopoly Case
Google is confronting an existential threat as the U.S. government tries to break up the company as punishment for turning its revolutionary search engine into an illegal monopoly. From a report: The drama began to unfold Monday in a Washington courtroom as three weeks of hearings kicked off to determine how the company should be penalized for operating a monopoly in search. In its opening arguments, federal antitrust enforcers also urged the court to impose forward-looking remedies to prevent Google from using artificial intelligence to further its dominance. "This is a moment in time, we're at an inflection point, will we abandon the search market and surrender them to control of the monopolists or will we let competition prevail and give choice to future generations," said Justice Department attorney David Dahlquist.
The proceedings, known in legal parlance as a "remedy hearing," are set to feature a parade of witnesses that includes Google CEO Sundar Pichai. The U.S. Department of Justice is asking a federal judge to order a radical shake-up that would ban Google from striking the multibillion dollar deals with Apple and other tech companies that shield its search engine from competition, share its repository of valuable user data with rivals and force a sale of its popular Chrome browser. Google's attorney, John Schmidtlein, said in his opening statement that the court should take a much lighter touch. He said the government's heavy-handed proposed remedies wouldn't boost competition but instead unfairly reward lesser rivals with inferior technology. "Google won its place in the market fair and square," Schmidtlein said.

The Bees Are Disappearing Again
"Honeybee colonies are under siege across much of North America..." reported the New York Times last week. [Alternate URL here.] Last winter beekeepers across America "began reporting massive beehive collapses. More than half of the roughly 2.8 million colonies collapsed, costing the industry about $600 million in economic losses..."
America's Department of Agriculture says "sublethal exposure" to pesticides remains one of the biggest factors threatening honeybees, according to the article — but it's one of several threats. "Parasites, loss of habitat, climate change and pesticides threaten to wipe out as much as 70% or more of the nation's honeybee colonies this year, potentially the most devastating loss that the nation has ever seen."
Some years are worse than others, but there has been a steady decline over time. Scientists have named the phenomenon colony collapse disorder: Bees simply disappear after they fly out to forage for pollen and nectar. Illness disables their radar, preventing them from finding their way home. The queen and her brood, if they survive, remain defenseless.
The precise causes remain unknown.
Bee colonies have become even more vulnerable because of the increase in extreme weather conditions, including droughts, heat waves, monster hurricanes, explosive wildfires and floods that have damaged or destroyed the bees and the vegetation they pollinate. If that isn't bad enough, parasites — and other creatures researchers refer to as "biotic" threats that prey on bees — proliferate when there is damage to ecosystems.
All that means that the U.S. beekeeping industry has contracted by about 2.9% over the past five years, according to data collected by IBISWorld, a research firm. Annual loss rates have been increasing among all beekeepers over the past decade with the most significant colony collapses in commercial operations happening during the past five years.
The article notes that "compounding the troubles for the bee industry are recent federal cuts" proposed by DOGE to America's Department of Agriculture, "where researchers were studying ways to protect the nation's honeybees." And while federal policies like tariffs could make farming more expensive, "Beekeepers also often depend on immigrants to manage their hives and to help produce commercial honey..."

Arch Linux Is the Latest Distro Replacing Redis with Valkey
In NoSQL database news, Arch Linux "is the latest Linux distribution replacing its Redis packages with the Valkey fork," reports Phoronix.
Valkey is backed by the Linux Foundation, Google, Amazon Web Services, and Oracle, which the article points out is due to Redis's decision last year to shift the upstream Redis license from a BSD 3-clause to RSALv2 and SSPLv1.
Valkey is replacing Redis in the Arch Linux extra repository and after a two week period the Redis package will be moved out to AUR and receive no further updates. Users are encouraged to migrate to Valkey as soon as possible.

A Musician's Brain Matter Is Still Making Music Three Years After His Death
An anonymous reader quotes a report from Popular Mechanics: American composer Alvin Lucier was well-known for his experimental works that tested the boundaries of music and art. A longtime professor at Wesleyan University (before retiring in 2011), Alvin passed away in 2021 at the age of 90. However, that wasn't the end of his lifelong musical odyssey. Earlier this month, at the Art Gallery of Western Australia, a new art installation titled Revivification used Lucier's "brain matter" -- hooked up to an electrode mesh connected to twenty large brass plates -- to create electrical signals that triggered a mallet to strike the varying plates, creating a kind of post-mortem musical piece. Conceptualized in collaboration with Lucier himself before his death, the artists solicited the help of researchers from Harvard Medical School, who grew a mini-brain from Lucier's white blood cells. The team created stem cells from these white blood cells, and due to their pluripotency, the cells developed into cerebral organoids somewhat similar to developing human brains. "At a time when generative AI is calling into question human agency, this project explores the challenges of locating creativity and artistic originality," the team behind Revivification told The Art Newspaper. "Revivification is an attempt to shine light on the sometimes dark possibilities of extending a person's presence beyond the seemed finality of death."
"The central question we want people to ask is: could there be a filament of memory that persists through this biological transformation? Can Lucier's creative essence persist beyond his death?" the team said.

GoDaddy Registry Error Knocked Zoom Offline for Nearly Two Hours
A communication error between GoDaddy Registry and Markmonitor took Zoom's services offline for almost two hours on Wednesday when GoDaddy mistakenly blocked the zoom.us domain. The outage affected all services dependent on the zoom.us domain.
GoDaddy's block prevented top-level domain nameservers from maintaining proper DNS records for zoom.us. This created a classic domain resolution failure -- when users attempted to connect to any zoom.us address, their requests couldn't be routed to Zoom's servers because the domain effectively disappeared from the internet's addressing system.
Video meetings abruptly terminated mid-session with browser errors indicating the domain couldn't be found. Zoom's status page (status.zoom.us) went offline, hampering communication efforts. Even Zoom's main website at zoom.com failed as the content delivery network couldn't reach backend services hosted on zoom.us servers. Customer support capabilities collapsed when account managers using Zoom's VoIP phones lost connectivity.
Resolution required coordinated effort between Zoom, Markmonitor, and GoDaddy to identify and remove the block. After service restoration, users needed to manually flush their DNS caches using command line instructions (including the sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder command for Mac users).

Police Using AI Personas to Infiltrate Online Activist Spaces, Records Reveal
samleecole shares a report from 404 Media: American police departments near the United States-Mexico border are paying hundreds of thousands of dollars for an unproven and secretive technology that uses AI-generated online personas designed to interact with and collect intelligence on "college protesters," "radicalized" political activists, and suspected drug and human traffickers, according to internal documents, contracts, and communications 404 Media obtained via public records requests. Massive Blue, the New York-based company that is selling police departments this technology, calls its product Overwatch, which it markets as an "AI-powered force multiplier for public safety" that "deploys lifelike virtual agents, which infiltrate and engage criminal networks across various channels." According to a presentation obtained by 404 Media, Massive Blue is offering cops these virtual personas that can be deployed across the internet with the express purpose of interacting with suspects over text messages and social media. [...]
While the documents don't describe every technical aspect of how Overwatch works, they do give a high-level overview of what it is. The company describes a tool that uses AI-generated images and text to create social media profiles that can interact with suspected drug traffickers, human traffickers, and gun traffickers. After Overwatch scans open social media channels for potential suspects, these AI personas can also communicate with suspects over text, Discord, and other messaging services. The documents we obtained don't explain how Massive Blue determines who is a potential suspect based on their social media activity. Salzwedel, of Pinal County, said "Massive Blue's solutions crawl multiple areas of the Internet, and social media outlets are just one component. We cannot disclose any further information to preserve the integrity of our investigations." [...] Besides scanning social media and engaging suspects with AI personas, the presentation says that Overwatch can use generative AI to create "proof of life" images of a person holding a sign with a username and date written on it in pen.

'We Are Not Programmed to Die,' Says Nobel Laureate Venki Ramakrishnan
In a recent interview with Wired, Nobel laureate Venkatraman Ramakrishnan discusses his book Why We Die, in which he argues that death is not genetically programmed but rather a consequence of evolution favoring reproduction over longevity. Here are some of the most thought-provoking excerpts:
WIRED: Professor Ramakrishnan, the crucial question in your book is why we die. But exactly what is death?
Venki Ramakrishnan: By death, we mean the irreversible loss of the ability to function as a coherent individual. It is the result of the failure of a critical system or apparatus, for example, heart, brain, lung, or kidney failure. In this sense there is an apparent paradox: When our organism, as a whole, is alive, millions of cells within us are constantly dying, and we do not even realize it. On the other hand, at the time of death, most of the cells in our bodies are still alive, and entire organs are still functioning and can be donated to people in need of transplantation. But at that point the body has lost the ability to function as a whole. In this sense, it is therefore important to distinguish between cell death and death of the individual.
Speaking of death and aging, you say in your most recent book that you "wanted to offer an objective look at our current understanding of the two phenomena." What was the biggest surprise or most deeply held belief that you had to reconsider while writing and researching this work?
There have been several surprises, actually. One is that death, contrary to what one might think, is not programmed by our genes. Evolution does not care how long we live, but merely selects the ability to pass on our genes, a process known as "fitness" in evolutionary biology. Thus, the traits that are selected are those that help us survive childhood and reproduce. And it is these traits, later in life, that cause aging and decline. Another curious finding was the fact that aging is not simply due to wear and tear on cells. Wear and tear happens constantly in all living things, yet different species have very different lifespans. Instead, lifespan is the result of a balance between the expenditure of resources needed to keep the organism functioning and repairing it and those needed to make it grow, mature, and keep it healthy until it reproduces and nurtures offspring.
Do you think there is an aspect of the biology of aging that is still deeply misunderstood by the general public?
Certainly the indefinite extension of life. Although in principle there are no laws or constraints that prevent us from living much longer than we do currently, great longevity or "eternal youth" are still far off, and very significant obstacles to increasing our maximum life expectancy remain. We must also beware of the pseudoscience -- and business -- around the concepts of "anti-aging" or the "reversal of aging." These are often baseless concepts, unsupported by hard evidence, even though they may use language that sounds scientific. Unfortunately, we are all afraid of growing old and dying, so we are very sensitive to any claim that promises to help us avoid it. [...]
What do you think are the social and ethical implications of our desire to live longer?
Ever since we became aware of our mortality, we have desired to defeat aging and death. However, our individual desires may conflict with what is best for society. A society in which fertility rates are very low and lifespans are very high will be a stagnant society, with very slow generational turnover, and probably much less dynamic and creative. The Nobel Prize-winning South American novelist Mario Vargas Llosa, who recently passed away, expressed it best: "Old age on the one hand terrifies us, but when we feel anxious, it is important to remember how terrible it would be to live forever. If eternity were guaranteed, all the incentives and illusions of life would vanish. This thought can help us live old age in a better way."

Microsoft Confirms Classic Outlook CPU Usage Spikes, Offers No Fix
Microsoft has acknowledged that Classic Outlook can mysteriously transform into a system resource hog, causing CPU usage spikes between 30-50% and significantly increasing power consumption on both Windows 10 and 11 systems.
Users first reported the issue in November 2024, but Microsoft only confirmed the problem this week, offering little resolution beyond stating that "the Outlook Team is investigating this issue." The company's sole workaround involves forcing a switch to the Semi-Annual Channel update through registry edits -- an approach many enterprise environments will likely avoid. Microsoft hasn't announced a definitive end date for Classic Outlook, but the company continues pushing users toward its New Outlook client despite its incomplete feature set.

Harvard's RoboBee Masters Landing, Paving Way For Agricultural Pollination
After more than a decade of development, Harvard's insect-sized flying robot, RoboBee, has successfully learned to land using dragonfly-inspired legs and improved flight controls. The researchers see RoboBee as a potential substitute for endangered bees, assisting in the pollination of plants. From a report: RoboBee is a micro flying robot that Harvard has been developing since 2013. As the name suggests, it is the size of a bee, capable of flying like a bee and hovering in mid-air. Its wings are 3 cm long and it weighs only 0.08 g. The weight was reduced by using light piezoelectric elements instead of motors. Piezoelectric elements change shape when an electric current flows through them. The researchers were able to make RoboBee flap its wings 120 times per second by turning the current on and off, which is similar to actual insects.
While RoboBee exhibited flight capabilities comparable to those of a bee, the real problem was landing. Being too light and having short wings, it could not withstand the air turbulence generated during landing. It is easy to understand if you think about the strong winds generated when a helicopter approaches the ground. Christian Chan, a graduate student at Harvard who participated in the research, said, "Until now, it was a matter of shutting off the robot while it attempted to land and praying for a proper touchdown."
To ensure RoboBee's safe landing, it was important to dissipate energy just before touchdown. Hyun Nak-Seung, a professor at Purdue University who participated in the development of RoboBee, explained, "For any flying object, the success of landing depends on minimizing speed just before impact and rapidly dissipating energy afterward. Even for tiny flapping like RoboBee's, the ground effect cannot be ignored, and after landing, the risk of bouncing or rolling makes the situation more complex." The findings have been published in the journal Science Robotics.

Discord Begins Testing Facial Recognition Scans For Age Verification
Discord has begun testing age verification via facial scans or ID uploads for users in the UK and Australia seeking access to sensitive content. "The chat app's new process has been described as an 'experiment,' and comes in response to laws passed in those countries that place guardrails on youth access to online platforms," reports Gizmodo. From the report: Users may be asked to verify their age when encountering content that has been flagged by Discord's systems as being sensitive in nature, or when they change their settings to enable access to sensitive content. The app will ask users to scan their face through a computer or smartphone webcam; alternatively, they can scan a driver's license or other form of ID. "We're currently running tests in select regions to age-gate access to certain spaces or user settings," a spokesperson for Discord said in a statement. "The information shared to power the age verification method is only used for the one-time age verification process and is not stored by Discord or our vendor. For Face Scan, the solution our vendor uses operates on-device, which means there is no collection of any biometric information when you scan your face. For ID verification, the scan of your ID is deleted upon verification."

Following Layoffs, Automattic Employees Discover Leak-Catching Watermarks
An anonymous reader quotes a report from 404 Media: As part of the company's months-long obsession with catching employees leaking internal developments to the press, staff at Wordpress parent company Automattic recently noticed individually-unique watermarks on internal sites, according to employees who spoke to 404 Media. Automattic added the watermarks to an internal employee communications platform called P2. P2 is a WordPress product other workplaces can also use. There are hundreds of P2 sites across teams at Automattic alone; many are team-specific, but some are company-wide for announcements. The watermarks in Automattic's P2 instance are nearly invisible, rendered as a pattern overlaid on the site's white page backgrounds. Zooming in or manually changing the background color reveals the pattern. If, for example, a journalist published a screenshot leaked to them that was taken from P2, Automattic could theoretically identify the employee who shared it.
In October, as part of a series of buyout offers meant to test employee's loyalty to his leadership, Automattic CEO Matt Mullenweg issued a threat for anyone speaking to the press, saying they should "exit gracefully, or be fired tomorrow with no severance." Earlier this month, the company laid off nearly 300 people. [...] It's not clear when the watermarks started appearing on P2, and Automattic has not responded to a request for comment. But Mullenweg has been warring with web hosting platform WP Engine -- and as the story has developed, seemingly with his own staff -- since last year. [...] One Automattic employee told me they don't think anyone is shocked by the watermarking, considering Mullenweg's ongoing campaign to find leakers, but that it's still adding to the uncertain, demoralized environment at the company. "Can't help but feel even more paranoid now," they said.

Older People Who Use Smartphones 'Have Lower Rates of Cognitive Decline'
An anonymous reader quotes a report from The Guardian: Fears that smartphones, tablets and other devices could drive dementia in later life have been challenged by research that found lower rates of cognitive decline in older people who used the technology. An analysis of published studies that looked at technology use and mental skills in more than 400,000 older adults found that over-50s who routinely used digital devices had lower rates of cognitive decline than those who used them less. It is unclear whether the technology staves off mental decline, or whether people with better cognitive skills simply use them more, but the scientists say the findings question the claim that screen time drives what has been called "digital dementia".
"For the first generation that was exposed to digital tools, their use is associated with better cognitive functioning," said Dr Jared Benge, a clinical neuropsychologist in UT Health Austin's Comprehensive Memory Center. "This is a more hopeful message than one might expect given concerns about brain rot, brain drain, and digital dementia." Benge and his colleague Dr Michael Scullin, a cognitive neuroscientist at Baylor University in Texas, analysed 57 published studies that examined the use of digital technology in 411,430 adults around the world. The average age was 69 years old and all had a cognitive test or diagnosis. The scientists found no evidence for the digital dementia hypothesis, which suggests that a lifetime of using digital technology drives mental decline. Rather, they found that using a computer, smartphone, the internet or some combination of these was associated with a lower risk of cognitive impairment. The details have been published in Nature Human Behaviour. "Using digital devices in the way that we use televisions -- passive and sedentary, both physically and mentally -- is not likely to be beneficial," said Scullin. "But, our computers and smartphones also can be mentally stimulating, afford social connections, and provide compensation for cognitive abilities that are declining with ageing. These latter types of uses have long been regarded as beneficial for cognitive ageing."

OpenAI is Building a Social Network
An anonymous reader shares a report: OpenAI is working on its own X-like social network, according to multiple sources familiar with the matter. While the project is still in early stages, we're told there's an internal prototype focused on ChatGPT's image generation that has a social feed. CEO Sam Altman has been privately asking outsiders for feedback about the project, our sources say. It's unclear if OpenAI's plan is to release the social network as a separate app or integrate it into ChatGPT, which became the most downloaded app globally last month.
Launching a social network in or around ChatGPT would likely increase Altman's already-bitter rivalry with Elon Musk. In February, after Musk made an unsolicited offer to purchase OpenAI for $97.4 billion, Altman responded: "no thank you but we will buy twitter for $9.74 billion if you want." Entering the social media market also puts OpenAI on more of a collision course with Meta, which we're told is planning to add a social feed to its coming standalone app for its AI assistant. When reports of Meta building a rival to the ChatGPT app first surfaced a couple of months ago, Altman shot back on X again by saying, "ok fine maybe we'll do a social app."

Chinese Robotaxis Have Government Black Boxes, Approach US Quality
An anonymous reader quotes a report from Forbes: Robotaxi development is speeding at a fast pace in China, but we don't hear much about it in the USA, where the news focuses mostly on Waymo, with a bit about Zoox, Motional, May, trucking projects and other domestic players. China has 4 main players with robotaxi service, dominated by Baidu (the Chinese Google.) A recent session at last week's Ride AI conference in Los Angeles revealed some details about the different regulatory regime in China, and featured a report from a Chinese-American YouTuber who has taken on a mission to ride in the different vehicles.
Zion Maffeo, deputy general counsel for Pony.AI, provided some details on regulations in China. While Pony began with U.S. operations, its public operations are entirely in China, and it does only testing in the USA. Famously it was one of the few companies to get a California "no safety driver" test permit, but then lost it after a crash, and later regained it. Chinese authorities at many levels keep a close watch over Chinese robotaxi companies. They must get approval for all levels of operation which control where they can test and operate, and how much supervision is needed. Operation begins with testing with a safety driver behind the wheel (as almost everywhere in the world,) with eventual graduation to having the safety driver in the passenger seat but with an emergency stop. Then they move to having a supervisor in the back seat before they can test with nobody in the vehicle, usually limited to an area with simpler streets.
The big jump can then come to allow testing with nobody in the vehicle, but with full time monitoring by a remote employee who can stop the vehicle. From there they can graduate to taking passengers, and then expanding the service to more complex areas. Later they can go further, and not have full time remote monitoring, though there do need to be remote employees able to monitor and assist part time. Pony has a permit allowing it to have 3 vehicles per remote operator, and has one for 15 vehicles in process, but they declined comment on just how many vehicles they actually have per operator. Baidu also did not respond to queries on this. [...] In addition, Chinese jurisdictions require that the system in a car independently log any "interventions" by safety drivers in a sort of "black box" system. These reports are regularly given to regulators, though they are not made public. In California, companies must file an annual disengagement report, but they have considerable leeway on what they consider a disengagement so the numbers can't be readily compared. Chinese companies have no discretion on what is reported, and they may notify authorities of a specific objection if they wish to declare that an intervention logged in their black box should not be counted. On her first trip, YouTuber Sophia Tung found Baidu's 5th generation robotaxi to offer a poor experience in ride quality, wait time, and overall service. However, during a return trip she tried Baidu's 6th generation vehicle in Wuhan and rated it as the best among Chinese robotaxis, approaching the quality of Waymo.

OpenAI Unveils Coding-Focused GPT-4.1 While Phasing Out GPT-4.5
OpenAI unveiled its GPT-4.1 model family on Monday, prioritizing coding capabilities and instruction following while expanding context windows to 1 million tokens -- approximately 750,000 words. The lineup includes standard GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano variants, all available via API but not ChatGPT.
The flagship model scores 54.6% on SWE-bench Verified, lagging behind Google's Gemini 2.5 Pro (63.8%) and Anthropic's Claude 3.7 Sonnet (62.3%) on the same software engineering benchmark, according to TechCrunch. However, it achieves 72% accuracy on Video-MME's long video comprehension tests -- a significant improvement over GPT-4o's 65.3%.
OpenAI simultaneously announced plans to retire GPT-4.5 -- their largest model released just two months ago -- from API access by July 14. The company claims GPT-4.1 delivers "similar or improved performance" at substantially lower costs. Pricing follows a tiered structure: GPT-4.1 costs $2 per million input tokens and $8 per million output tokens, while GPT-4.1 nano -- OpenAI's "cheapest and fastest model ever" -- runs at just $0.10 per million input tokens.
All models feature a June 2024 knowledge cutoff, providing more current contextual understanding than previous iterations.

Can AI Help Manage Nuclear Reactors?
America's Department of Energy launched a federally funded R&D center in 1946 called the Argonne National Laboratory, and its research became the basis for all of the world's commercial nuclear reactors.
But it's now developed an AI-based tool that can "help operators run nuclear plants," reports the Wall Street Journal, citing comments from a senior nuclear engineer in the lab's nuclear science and engineering division:
Argonne's plan is to offer the Parameter-Free Reasoning Operator for Automated Identification and Diagnosis, or PRO-AID, to new, tech-forward nuclear builds, but it's also eyeing the so-called dinosaurs, some of which are being resurrected by companies like Amazon and Microsoft to help power their AI data centers. The global push for AI is poised to fuel a sharp rise in electricity demand, with consumption from data centers expected to more than double by the end of the decade, the International Energy Agency said Thursday. The owners of roughly a third of U.S. nuclear plants are in talks with tech companies to provide electricity for those data centers, the Wall Street Journal has reported.
PRO-AID performs real-time monitoring and diagnostics using generative AI combined with large language models that notify and explain to staff when something seems amiss at a plant. It also uses a form of automated reasoning — which uses mathematical logic to encode knowledge in AI systems — to mimic the way a human operator asks questions and comes to understand how the plant is operating [according to Richard Vilim, a senior nuclear engineer within the lab's nuclear science and engineering division].
The tool can also help improve the efficiency of the personnel needed to operate a nuclear plant, Vilim said. That's especially important as older employees leave the workforce. "If we can hand off some of these lower-level capabilities to a machine, when someone retires, you don't need to replace him or her," he said... Part of the efficiency in updating technology will come from consolidating the monitoring staff at a utility's nuclear plants at a single, centralized location — much as gas-powered plants already do.
It hasn't found its way into a commercial nuclear plant yet, the article acknowledges. But the senior nuclear engineer points out that America's newer gas-powered plants ended up being more automated with digital monitoring tools.
