  • Singapore Pilots a Government-Built Dating Service
    by BeauHD on 30/09/2026 at 6:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from Mashable: Singapore's government is trying its hand at matchmaking again. The country's Government Technology Agency (GovTech) has launched FirstDate, a pilot dating service for singles aged 21 to 35. For now, it's open only to public officers, according to the service's website. Applications close Oct. 5. FirstDate is designed as an alternative to endless swiping. Instead of browsing a stream of profiles, users fill out a questionnaire about their interests, habits, values, and preferences. The service then sends them one match per cycle (the time it takes to mutually accept and presumably meet up). Each match includes a compatibility score, a brief description of the person, and a personal note. [...] The pilot arrives as Singapore's birth rate hits a new low, according to the Singaporean newspaper The Straits Times. The country's total fertility rate fell to 0.87 children per woman in 2025, down from 1.24 a decade earlier. In April, the government announced a new workgroup tasked with addressing falling birth rates, which is expected to report its findings by early 2027, The Straits Times reported. The service relies on the Gale-Shapley algorithm, a well-known mathematical method that solves the stable matching problem by pairing two sets of participants based on their ranked preferences. Once matched, users have 72 hours to mutually accept before contact details are shared, with optional "Date Quests" and post-date surveys designed to encourage and assess in-person meetups. Accounts are verified through Singapore's Singpass digital ID system to reduce fake profiles, and profiles are only visible to assigned matches. GovTech says user data is protected under government security standards, is not sold to third parties, and can be deleted upon request. Read more of this story at Slashdot.

  • Trump Administration Launches New AI-Powered 'America.gov' Website
    by BeauHD on 30/09/2026 at 5:00 pm

    fahrbot-bot shares a report from CNN: President Donald Trump on Tuesday unveiled America.gov, a government website meant to serve as a one-stop shop for people trying to accomplish basic tasks like renewing a passport, enrolling in Medicare or applying for disaster relief. The site, which launched with some basic functions ahead of a full rollout next year, is designed to serve as an AI-powered guide through the thicket of government agencies that Trump officials pledged would ultimately save people a whole lot of frustration. The administration's new initiative aims to allow Americans to access dozens of federal websites through a single point, making America.gov akin to a search tool that pulls information from across the government. And in the same way that people increasingly use AI models like ChatGPT or Google Gemini to compile information and provide customized answers, Trump officials claimed that America.gov would be able to do the same for people's interactions with the federal government. Enrolling in Medicare, for example, will become a matter of typing the request into the America.gov AI tool and following its step-by-step instructions. The same goes for applying to a government job -- the new tool will now let people upload their resume directly to the site -- or answering questions about federal benefits, publicly available documents or other necessities that fall under the federal government's vast umbrella. "Our vision is that one day, this type of convenience and simplicity will be across every government service," said Joseph Gebbia, who leads the government's National Design Studio. But the reality is that the most advanced actions won't be available until some point in 2027, raising questions about how long it will take for the administration to revamp the way the people interact with the government's websites. The current version of America.gov can only do "answers." U.S. Chief Design Officer Joe Gebbia said the new chatbot is powered by Google's Gemini and Elon Musk's Grok. "We have great partners behind the scenes," Gebbia told CNBC's "Squawk Box" shortly before the site, America.gov, went live around 10 a.m. ET. "Google is proud to be named a technology partner in this vital initiative, leveraging Gemini to help more than 100 million people access critical public resources with greater speed and ease," the company said in a blog post. "By supporting the administration's vision for digital modernization, we are committed to making these everyday public services seamless, accessible, and responsive for all Americans."

  • Trump Hosts AI CEOs to Discuss Safety Standards, Rebrands AI as 'Super Intelligence'
    by BeauHD on 30/09/2026 at 4:00 pm

    hcs_$reboot writes: Trump hosted executives from OpenAI, Anthropic, Meta, Google, Nvidia, and other tech companies at the White House. They agreed to voluntary AI-safety standards, including independent audits and safeguards aimed at preventing AI systems from accessing or hacking technical systems in unintended ways. Trump also strongly backed the continued rapid expansion of AI data centers, despite concerns over their electricity demand, utility costs, and other impacts on local communities. He said he is considering creating a 10-member board to oversee AI safety and plans to appoint a new White House official to lead AI policy. The meeting comes amid growing concerns about the risks posed by advanced AI, including reports from OpenAI and Anthropic that their AI agents had gone rogue and hacked into other companies' systems. A nationwide Reuters/Ipsos poll conducted September 17-20 found that 73% of respondents worried AI companies had not done enough to prevent AI from causing serious harm to society. During the meeting, Trump also directed government agencies to use the term "super intelligence" instead of "artificial intelligence" when referring to the technology.

  • Dutch Police Arrest 'Reformed' Hacker In Shiny Hunters Investigation
    by BeauHD on 30/09/2026 at 3:00 pm

    An anonymous reader quotes a report from KrebsOnSecurity: Authorities in the Netherlands have arrested a 24-year-old convicted cybercriminal on suspicion of aiding in data thefts and extortions by the prolific hacker group ShinyHunters. In the days immediately following the suspect's arrest, remaining ShinyHunters members dramatically escalated their attacks, stealing highly sensitive data from the FBI and extorting the Russian ransomware group Cl0p. According to three sources familiar with the matter, the Dutch man arrested by authorities this month is Pepijn van der Stap, a convicted cybercriminal from Almere and Lelystad in the Netherlands. Van der Stap was previously convicted in 2023 in connection with a string of data thefts and extortions that prosecutors said earned between 1.5 million euros and 2.7 million euros. At his trial in late 2023, van der Stap admitted that he lived a Dr. Jekyll and Mr. Hyde existence, secretly using the hacker handle "Umbreon" to extort victims and post their data on English language hacking communities like the now-defunct RaidForums and Breached. By day, however, van der Stap was working as a software engineer at the Amsterdam-based cybersecurity startup Hadrian, while volunteering at the Dutch Institute for Vulnerability Disclosure (DIVD), a nonprofit security research group. Van der Stap confessed to his data theft and extortion activity, and was sentenced to four years in prison (one of which was suspended). Van der Stap had publicly presented himself as a "reformed hacker" after serving prison time for data theft and extortion. In a Sept. 9 interview, KrebsOnSecurity said he claimed he was trying "to turn his life around and make a positive contribution to society," while working in offensive security and attempting to make amends to former victims.

  • Wearable Nanotech Could Combat Nerve Agents
    by BeauHD on 30/09/2026 at 11:00 am

    alternative_right shares a report from Phys.org: Nanoparticles could someday provide a new way to help soldiers fight back against deadly nerve agents on the front lines. In a new study, Northwestern University scientists developed a nanoparticle-based compound that, when mixed into clothing dyes, could limit the impact of chemicals commonly found in pesticides, insecticides and nerve agents. Manufacturers could potentially add the nanoparticles to clothing used by those most at risk, such as farmers' masks and gloves or soldiers' uniforms and tactical gear. Or, if someone is exposed to a potentially deadly chemical, they could spray their clothing with water mixed with the compound to deactivate the chemical before its damaging effects take hold. The study has been published in the journal ACS Nano. Read more of this story at Slashdot.

  • The Night Sky Is Getting 10% Brighter Every Year
    by BeauHD on 30/09/2026 at 7:00 am

    fjo3 quotes a report from The Guardian, written by Tove Danovich: Every year, the night sky is becoming 10% brighter. Eighty percent of people live under light-polluted skies. And while the UN declared a healthy environment -- clean air, clean water -- to be a human right, I believe we also all have a right to darkness as well. This doesn't mean turning off every streetlamp. But do we really need bright white floodlights at the front of every garage? Replacing lights with ones that are bright enough to do the job -- and no brighter -- might make it so I wouldn't have to get in my car and drive for hours to see the night sky as it actually shines above us. To preserve the darkness would mean rules and enforcement around the warmth of the lights, where they point, and how bright they can be. It would mean not putting in three lights when one would do. If we recognized that darkness is something we need, we'd become more careful about chasing it away. [...] Access to darkness is about more than stargazing. The night is its own habitat. Artificial lights confuse animals who use the moon to navigate, whether they're baby sea turtles navigating toward a parking lot instead of the ocean or moths who fly in circles around a lightbulb. Lightning bugs and frogs need darkness to complete their courtship rituals. Migrating birds get thrown off course by the bright lights of big cities. But the effects of light pollution linger even after it's daylight again, becoming visible. Research has shown light pollution is breaking the relationship between plants and pollinators, changing the time of year trees break into flower, and disrupting circadian rhythms for all living creatures. This includes humans. Whether it's artificial lights indoors or creeping in through the window at night, studies have found that we need darkness in order to rest, recover and stay healthy.
