A Fedora contributor account recently came under scrutiny for apparently AI-generated activity that disrupted the project's bug tracker. 

Pokemon Go players' optional location scans reportedly helped train Niantic Spatial's visual positioning system, which uses camera imagery and 3D maps to navigate when GPS is unavailable or jammed. According to DroneXL, that technology is now being paired with Vantor's drone navigation software for military and intelligence use, raising questions about whether gamers understood that footage collected for in-game rewards could eventually support defense systems. From the report: The pipeline runs from a mobile game to the battlefield in three steps. Players scanned the physical world. Niantic Spatial turned those scans into a 3D map that lets a machine locate itself by sight when satellite signals fail. And in December 2025, Niantic Spatial announced a partnership with Vantor, the defense and intelligence firm formerly known as Maxar Intelligence, to fuse that ground-level system with Vantor's aerial navigation software for use in GPS-denied operations. I have spent years covering how drones lose their way the moment an electronic warfare unit switches on a jammer, a problem that has spread from the battlefield into civilian airspace, from Ukrainian workshops cycling through navigation generations to American programs scrambling for alternatives. The unsettling part of this story is not the technology. It is where the training data came from, and whether the people who supplied it would have agreed had anyone explained the destination. "Now as part of Scopely (the Saudi-owned company that acquired Niantic last year for $3.5 billion), Pokemon GO data is not shared with Niantic Spatial," a company spokesperson said in a statement to Kotaku. "AR Scans collected through Pokemon GO were submitted voluntarily by players who opted into the feature and were subject to the applicable Terms of Service and Privacy Policy at the time. The discontinuation of AR scanning and the end of data sharing with Niantic Spatial were part of the transition planning associated with Pokemon GO's move to Scopely."

Riverside County has launched an 8-mile "smart freeway" pilot on northbound I-15 near Temecula, using roadway sensors and an algorithm to coordinate ramp meters and suggest speeds rather than widening the freeway. Officials say the $33 million project could reduce stop-and-go traffic and travel times. According to SFGATE, similar systems in Australia and Denver reportedly cutting delays by 20% to 65%. From the report: Unlike typical on-ramp stoplights that run on a timer lasting a few seconds, Interstate 15 drivers could find themselves waiting up to four minutes or even longer while the system determines the necessary speed for traffic entering the freeway. By spacing out the cars, transportation officials hope to improve traffic flow, reduce stop-and-go traffic and decrease the amount of time that travelers have to spend on the freeway. The transportation commission spent $33 million to build the project, which will run for two years. Riverside County Transportation Commission spokesperson David Knudsen told SFGATE that if the program is successful, the agency will work with Caltrans to deploy it elsewhere in the county and then potentially to other traffic choke points in California. "This system is a lot less expensive than trying to build new lanes, and so the idea here is let's make the system that we have work better," he said. Knudsen said the program is not managed by artificial intelligence but instead uses advanced sensors in the roadway to monitor real-time traffic conditions and make adjustments. The stretch of freeway that connects Temecula at the Riverside/San Diego County line to the Interstate 215 interchange in Murrieta can be notoriously clogged. What can be less than a 10-minute drive with no traffic can take between 25 and 45 minutes during the afternoon peak period, according to the transportation commission. "The intent is to create a consistent flow of traffic on the freeway system, and the coordinated ramp metering among the three on-ramps ... will help do that," Knudsen said. "If we can manage that, then we can help prevent that stop-and-go traffic frustration that so many people feel ... on the freeway."

An anonymous reader quotes a report from Bloomberg: While traditional hotspots in the region such as Thailand, South Korea and Malaysia focus on services such as cosmetic surgery, IVF or physicals, China is trying to differentiate itself by providing some of the world's most advanced procedures. "There are two reasons why a patient travels for medical treatments: availability of advanced treatments and price," said Victor Cao, operations director of Joyful Medical, an agency in Shanghai that connects international patients to advanced cancer therapies in China. "Chinese people used to travel overseas for treatments that were not available at home, but now tables have turned." As expanding visa-free policies eased travel in the past year or so, videos are proliferating on social media of foreigners recounting their positive experiences of treatment in China, usually for consumer procedures like acupuncture and tooth scaling. But one treatment that's more quietly gaining traction is CAR-T, among the most promising breakthroughs in oncology but unavailable in most countries, or extremely costly. The process sees doctors collect T cells from the patient's blood then modify them in a lab to produce a special receptor, CAR, that can bind to a specific protein on cancer cells. These engineered cells are then multiplied into large numbers and infused back into the patient. The CAR-T cells seek out cancer cells carrying the target antigen and kill them. In the US, one single infusion can cost between $300,000 to $475,000, according to the American Cancer Society. In China, the equivalent costs about $150,000 to $180,000, and it could get even cheaper -- its drug regulator recently accepted a marketing application for a therapy aimed to be priced below 300,000 yuan ($44,000). China's medical tourism market remains in its infancy. Lecheng International Medical Tourism Pilot Zone in Hainan, which was designated as the country's only special medical zone in 2013, treated just a few thousand foreign medical tourists last year, compared to hundreds of thousands of domestic patients who visited. There, patients can access advanced drugs, devices, and therapies approved in other countries but not elsewhere in mainland China. But China is pushing to upgrade its economy and reshape its global image from just a manufacturing hub into a provider of high-value services, and demand for medical tourism is surging. Globally, the market is estimated at around $34 billion and expected to reach $126 billion by 2035, according to San Francisco-based Grand View Research. Meanwhile, China's sector is projected to grow from $1.3 billion in 2025 to $3.4 billion by 2035, according to New York-based firm Market Research Future. "The patients chose China for something they can't get at home," said Shi Haoying, the group's founder and chief executive officer. "I think the growing attention to medical tourism to China is the inevitable result of long-term accumulation and development in many areas, such as growing medical technologies, quality of service and cost-effectiveness." Jeroen Groenewegen-Lau, an analyst at the Mercator Institute for China Studies, added: "Many new treatments, including in very advanced areas, are made in China but too advanced for the state of its healthcare system and the ability of its patients to pay for these things. It's in China's interest to integrate into the international system."

Two recent studies argue that smartphones may have contributed to falling birthrates by reducing in-person social interaction, sexual frequency, and other conditions tied to unintended pregnancies. "One of the studies published in May is called 'The Collapse of Teen Fertility in the Digital Era' and the other, published just Monday, is titled 'Is the iPhone Birth Control? Causal Evidence from AT&T's 2007-2011 Carrier Monopoly,'" reports KTLA. "Both were chronicled in a New York Times piece by political writer Sabrina Tavernise on Monday." Slashdot reader sabbede submitted the story. From the report: The one from May, authored by two University of Cincinnati professors, posits that teen fertility "collapsed globally" starting around 2007 -- the same year the first iPhone was released. "Smart phones changed how teens spend time with each other ... this change in turn drove the collapse in teen fertility," the study's abstract reads. "Once enough teens are on the phone, being on the phone is where the peer network is; in-person time falls sharply, and with it the unstructured contact in which most unintended teen conceptions occur." The study claimed that countries "across the income and policy spectrum" were affected by the teen fertility drop, and that researchers used data from multiple countries, including the U.S., England and Wales, to rule out "country-specific contraceptive access and welfare reform stories." "This model predicts that the shift towards the phone-mediated equilibrium affects multiple aspects of teen behavior," the abstract continues, concluding that "the same instrument that produces a collapse in teen fertility produces a surge in teen suicides." The study published on Monday looks more closely at the United States, explaining that nationwide general fertility rates have fallen 22% since 2007. "[This is] a sustained decline not readily explained by economic conditions, contraceptive use, housing or childcare costs, or other commonly cited factors," the National Bureau of Economic Researchers study states. "We assess the potential role of a different shock: the diffusion of the smartphone." As mentioned before, the first iPhone was rolled out in 2007, and this study makes use of that timeframe as "a natural experiment" by using data from 2007 through 2011, when iPhones were only sold on AT&T. "From June 2007 through February 2011, the device was sold only on AT&T, allowing us to identify its effect from variation in AT&T's mobile broadband coverage," the study says. "Entropy-balanced Poisson and synthetic difference-in-differences event studies imply that access to the iPhone reduced births by 4.5-8.0% at ages 15-19 and 3.2-6.6% at ages 20-24, with statistically significant but smaller declines among older cohorts. Placebo analyses applied to Verizon and Sprint's pre-2011 coverage footprint are null. Taken together, these cohort effects imply that the diffusion of the iPhone deepened the decline in births among women under 30 while suppressing the rise in births among older women." "Overall, the diffusion of the iPhone explains 33-52% of the decline in the general fertility rate among women aged 15-44," researchers continued. "National-survey evidence on time use and sexual behavior is consistent with the iPhone reducing in-person interactions, increasing pornography use and reducing sexual frequency."

Polish lawmakers have voted to criminalize "trash streaming," with up to five years in prison for online broadcasts of serious crimes such as rape or murder, animal cruelty, humiliating violence, gambling promotion, or even simulated depictions of those acts. Reuters reports: The move is part of a broader push by Poland to tighten regulation of online content. Recent measures include banning the use of mobile phones by children under 16 in schools and introducing stricter age verification rules to access pornography. Under the new provisions, broadcasting crimes punishable by more than five years in prison, including murder or rape, will itself be classed as a separate offence punishable by up to five years behind bars. The law also covers content showing cruelty to animals, violence aimed at humiliating others, and the promotion of gambling. The same penalties will apply to individuals who simulate or falsely portray the commission of such crimes while streaming, lawmakers said.

From white-boarding my ideas on a Google Doc, to writing a formal design document in Crosswords, my ability to communicate technical ideas clearly is being put to the test.

Writing documentation is critical to guide others’ understanding of the code and choices made on a particular codebase. Especially when several developers are introduced to the system, a way to reference material leads to more preparedness to contribute to the codebase.

I wrote a design document introducing the concepts I would like to implement towards creating a way to generate a dynamic grid. Critique is welcome.

Standard libipuz crosswords currently rely on using an existing dictionary to fill a static box of X length x Y width. However, the implementation of vocab puzzles goes against this logic and instead generates a new grid of N length x M width based on a list of 0 <= W <= 30 words of 1 <= L <= 25 characters long.

I reconsidered the idea of using a GArray to store unplaced words because I want something idempotent. To avoid unwanted time complexity bloat, the backend should not carry the memory of unplaced words. Instead, the frontend will compare the generated grid against the original list to manage words that couldn’t be placed.

Integrating this new feature will be a fascinating technical challenge.

I created a new IpuzVocab class which inherits from IpuzCrossword. I learned how GNOME manages its developer documentation by writing a file myself to introduce this class. Writing this document made me think about the whole picture: how vocab puzzles handle grids, clues, and guesses, comparing it to standard crossword puzzles. I wrote the support to display a vocab puzzle in light and dark mode, with my next goal to integrate them via gi-docgen.
