Ancient Slashdot reader Alain Williams shares a report from The Guardian: Mark Zuckerberg has faced questions over why a small cruise ship in south-east Alaska rescued a stranded skiff and its crew when his 387ft superyacht had been closer. The Silicon Valley billionaire's yacht, worth a reported $300 million, is said to have "repeatedly" declined to assist when a nearby boat called for help last week. Zuckerberg, CEO of Facebook and Instagram owner Meta Platforms, was not on board at the time, a spokesperson told Forbes. When a nearby 21ft skiff ran out of fuel between Petersburg and Juneau, the Alaska Beacon reported operators of a cruise ship that was further away than Zuckerberg's yacht came to the rescue. "I'm on a small-ship Alaska cruise with my son," a passenger on the UnCruise Adventures ship Wilderness Legacy posted on Bluesky. "Our boat rescued a stranded vessel last night and apparently we did that after the Coast Guard radioed Mark Zuckerberg's yacht -- which was closer -- and they repeatedly refused to respond. (There was near unanimous booing when the captain announced this)." A spokesperson for Zuckerberg told Forbes that the yacht crew had been operating on a different radio channel and "the assist was already under way" by the time they discovered the broadcast.

The Democratic brand is just too toxic in large swaths of the country.

Longtime Slashdot reader DF5JT writes: On July 26, I posted a single announcement in r/backgammon: GNU Backgammon for Android, GPLv3, the first standalone backgammon engine on F-Droid. Reddit's spam filter removed the post and permanently banned my 11-year, 30,000-karma account -- the result is publicly visible at reddit.com/user/OE1FEU. To this day, Reddit has given no reason whatsoever, although Article 17 of the EU's Digital Services Act makes a statement of reasons mandatory. The only appeal channel is a 250-character web form that sends no confirmation and has never been answered; Reddit's own help text admits: "you may not have received a message to your inbox." A GDPR export of 11 years of data came to 7.2 MB; every post was truncated after a few lines, with zero data about the ban decision. So I spent one day escalating through every mechanism the EU provides: certified out-of-court dispute settlement at Austria's RTR, complaints with the Austrian and Dutch Digital Services Coordinators, the data protection authority (citing the ECJ's SCHUFA ruling on automated decisions), noyb, and Austria's consumer association. Bonus finding: the European Commission's DSA Transparency Database contains 14,067 Reddit statements of reasons for that week -- none for my ban -- and the Commission's own feedback form limits reports to 500 characters and crashed with a 500 Server Error. Is the DSA enforceable for ordinary users, or just paperwork?

alternative_right shares a report from 404 Media: Robotics companies promise that video-camera-toting security robots can deter and detect crime. But many companies are rethinking the approach after a trail of canceled contracts and questions about whether the artificial intelligence-powered bots are meeting the needs of businesses and local governments. Proof News found evidence of at least 21 security robot deployments since 2015. We contacted contract holders and combed news articles and determined that at least 13 of those programs have ended. Silicon Valley-based Knightscope secured the most security robot contracts, according to Proof's analysis, and also suffered the bulk of cancellations. For example, New York City's then-Mayor Eric Adams installed a Knightscope robot on the overnight shift at the Times Square subway station, but the program was scrapped when the pilot expired in 2024. City leaders did not respond to Proof News' questions about why the robot wasn't renewed. By the end of its assignment, it was reportedly gathering dust in an empty storefront. Outside Columbus, Ohio, the city of Dublin pulled the plug on a Knightscope robot in May, ending its two-year pilot program after less than 10 months. The city enlisted the robot, dubbed DubBot, to patrol a downtown park, but city spokeswoman Robyn Gray said it "did not fully meet our operational needs," and failed to identify any criminal incidents or lead to any tickets or arrests. [...] Seeking a new path forward in the security industry, Knightscope CEO William Santana Li said the company is forging a new model, combining its robots and AI-powered software with another key ingredient: human security guards. Knightscope announced it purchased Event Risk LLC, a national security guard firm, earlier this year. Knightscope has incurred net losses since inception in 2013, according to its most recent quarterly filing with the U.S. Securities and Exchange Commission, and is $273 million in debt. Knightscope hopes its pivot to incorporate people will give it a greater share of the physical security market -- which the company believes is worth an estimated $230 billion annually. Li declined to answer questions about the disbanded programs, but said in an email, "Technology cannot do everything -- and neither can people -- but the combination can be very powerful."

An anonymous reader shares a report from The Conversation, written by Hatim Sharif, a civil and environmental engineer who has "spent more than two decades staring at maps" and spatial data. Sharif finds one connection especially fascinating: the link between spatial reasoning and why taxi drivers seem to have lower rates of Alzheimer's. From the report: Taxi and ambulance drivers are less likely than workers in almost any other job to die of Alzheimer's disease. That was the surprising result of a 2024 study examining the death certificates of nearly 9 million people in the U.S. [...] Of the 9 million death certificates from January 2020 to December 2022 that researchers examined, taxi and ambulance drivers had the lowest risk of dying from Alzheimer's disease out of 443 occupations. After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer's, compared with 1 in 60 people overall. This pattern did not extend to other driving jobs. The researchers concluded that the key to reducing the risk of Alzheimer's was not driving itself but continuous real-time navigation: the constant work of locating yourself in space, tracking a destination and updating a mental map as conditions change. Drivers whose jobs relied on fixed or predetermined routes, like bus drivers and aircraft pilots, didn't seem to experience a similar advantage. Researchers believe the association between navigation-heavy work and lower Alzheimer's risk centers on the hippocampus, a part of the brain that governs memory and spatial navigation. It's one of the first brain regions that Alzheimer's damages: Problems with spatial navigation and orientation are among the earliest signs of the disease, sometimes surfacing before obvious memory loss. In one landmark 2000 study, neuroscientists compared the brains of licensed London taxi drivers with those of people who did not drive cabs. Their findings provided the first evidence via structural imaging that regions of the adult brain can measurably change under sustained navigational demand. To earn a license, London cabbies must memorize more than 25,000 streets within a 6-mile radius of Charing Cross, a challenge known as "The Knowledge" that takes three to four years. The researchers found that London taxi drivers had measurably more gray matter in the posterior hippocampus, a brain area tied to storing large-scale spatial maps. That volume tracked with experience: The longer someone had driven, the larger that part of the brain. The change was built through practice, not inherited. While people who are good at navigation might gravitate to this kind of job, the job itself does have an impact on the brain. Together, these two studies make a coherent case: Work that intensively exercises the hippocampus may reshape it, and that reshaping may protect against one of the most feared diseases of aging.
