  • Claude Code Is Coming To Slack
    by BeauHD on 09/12/2025 at 7:00 am

    Anthropic is bringing Claude Code directly into Slack, letting developers spin up coding sessions from chat threads and automate workflows without leaving the app. TechCrunch reports: Previously, developers could only get lightweight coding help via Claude in Slack -- like writing snippets, debugging, and explanations. Now they can tag @Claude to spin up a complete coding session using Slack context like bug reports or feature requests. Claude analyzes recent messages to determine the right repository, posts progress updates in threads, and shares links to review work and open pull requests. The move reflects a broader industry shift: AI coding assistants are migrating from IDEs (integrated development environment, where software development happens) into collaboration tools where teams already work. [...] While Anthropic has not yet confirmed when it would make a broader rollout available, the timing is strategic. The AI coding market is getting more competitive, and differentiation is starting to depend more on integration depth and distribution than model capability alone.

  • Cold Case Inquiries Stall After Ancestry.com Revisits Policy For Users
    by BeauHD on 09/12/2025 at 3:30 am

    An anonymous reader quotes a report from the New York Times: Since online genealogy services began operating, millions of people have sent them saliva samples in hopes of learning about their family roots and discovering far-flung relatives. These services also appeal to law enforcement authorities, who have used them to solve cold case murders and to investigate crimes like the 2022 killing of four University of Idaho students. Crime-scene DNA submitted to genealogy sites has helped investigators identify suspects and human remains by first identifying relatives. The use of public records and family-tree building is crucial to this technique, and its main tool has been the genealogy site Ancestry, which has vast amounts of individual DNA profiles and public records. More than 1,400 cases have been solved with the help of so-called genetic genealogy investigations, most of them with help from Ancestry. But a recent step taken by the site is now deterring many police agencies from employing this crime-solving technique. In August, Ancestry revised the terms and conditions on its site to make it clear that its services were off-limits "for law enforcement purposes" without a legal order or warrant, which can be hard to get, because of privacy concerns. This followed the addition last year to the terms and conditions that the services could not be used for "judicial proceedings." Investigators say the implications are dire and will result in crucial criminal cases slowing or stalling entirely, denying answers to grieving families. "Everyone who does this work has depended on the records database that Ancestry controls," said David Gurney, who runs Ramapo College's Investigative Genetic Genealogy Center in New Jersey. "Without it, casework is going to be a lot slower, and there will be some cases that can't be resolved at all." Read more of this story at Slashdot.

  • 193 Cybercrims Arrested, Accused of Plotting 'Violence-As-a-Service'
    by BeauHD on 09/12/2025 at 2:00 am

    Europol's GRIMM taskforce has arrested nearly 200 people accused of running or participating in "violence-as-a-service" schemes where cybercrime groups recruit youth online for real-world attacks. "These individuals are groomed or coerced into committing a range of violent crimes, from acts of intimidation and torture to murder," the European police said on Monday. The Register reports: GRIMM began in April, and includes investigators from Belgium, Denmark, Finland, France, Germany, Iceland, the Netherlands, Norway, Spain, Sweden, the UK, plus Europol experts and online service providers. During its first six months, police involved in this operation arrested 63 people directly involved in carrying out or planning violent crimes, 40 "enablers" accused of facilitating violence-for-hire services, 84 recruiters, and six "instigators," five of whom the cops labeled "high-value targets." [...] Many of the criminals involved in recruiting and carrying out these violence-for-hire services are also members of The Com. This is a loosely knit gang, primarily English speakers, involved in several interconnected networks of hackers, SIM swappers, and extortionists. Their reach has spread across the Atlantic, and over the summer, the FBI warned that a subset of this cybercrime group, called In Real Life (IRL) Com, poses a growing threat to youth. The FBI's security bulletin specifically called out IRL Com subgroups that offer swat-for-hire services, in which hoaxers falsely report shootings at someone's residence or call in bomb threats to trigger massive armed police responses at the victims' homes.

  • Nvidia Can Sell H200 Chips To China For 25% US Cut
    by BeauHD on 09/12/2025 at 1:30 am

    The Trump administration will allow Nvidia to resume selling H200 chips to China, but only if the U.S. government takes a 25% cut. Axios reports: Trump said on Truth Social that he'll allow Nvidia to sell H200 chips -- the generation of chips before its current, more-advanced Blackwell lineup -- to China, with the U.S. government pocketing a quarter of the revenue. He said he would apply "the same approach to AMD, Intel, and other GREAT American Companies." American defense hawks fear that China could use Nvidia chips to advance its military ambitions. Trump said Monday that the sales will be subject to "conditions that allow for continued strong National Security." The blockade remains in place for Nvidia's current generation of Blackwell chips, which will be replaced in the second half of 2026 by even more advanced Rubin chips. Huang said recently he was unsure if China would want the older chips. "We applaud President Trump's decision to allow America's chip industry to compete to support high paying jobs and manufacturing in America," Nvidia said in a statement. "Offering H200 to approved commercial customers, vetted by the Department of Commerce, strikes a thoughtful balance that is great for America." Read more of this story at Slashdot.

  • More Than 200 Environmental Groups Demand Halt To New US Datacenters
    by BeauHD on 09/12/2025 at 1:10 am

    An anonymous reader quotes a report from the Guardian: A coalition of more than 230 environmental groups has demanded a national moratorium on new datacenters in the U.S., the latest salvo in a growing backlash to a booming artificial intelligence industry that has been blamed for escalating electricity bills and worsening the climate crisis. The green groups, including Greenpeace, Friends of the Earth, Food & Water Watch and dozens of local organizations, have urged members of Congress to halt the proliferation of energy-hungry datacenters, accusing them of causing planet-heating emissions, sucking up vast amounts of water and exacerbating electricity bill increases that have hit Americans this year. "The rapid, largely unregulated rise of datacenters to fuel the AI and crypto frenzy is disrupting communities across the country and threatening Americans' economic, environmental, climate and water security," the letter states, adding that approval of new data centers should be paused until new regulations are put in place. The push comes amid a growing revolt against moves by companies such as Meta, Google and Open AI to plow hundreds of billions of dollars into new datacenters, primarily to meet the huge computing demands of AI. At least 16 datacenter projects, worth a combined $64 billion, have been blocked or delayed due to local opposition to rising electricity costs. The facilities' need for huge amounts of water to cool down equipment has also proved controversial, particularly in drier areas where supplies are scarce. [...] At the current rate of growth, datacenters could add up to 44m tons of carbon dioxide to the atmosphere by 2030, equivalent to putting an extra 10m cars on to the road and exacerbating a climate crisis that is already spurring extreme weather disasters and ripping apart the fabric of the American insurance market. But it is the impact upon power bills, rather than the climate crisis, that is causing anguish for most voters, acknowledged Emily Wurth, managing director of organizing at Food & Water Watch, the group behind the letter to lawmakers. "I've been amazed by the groundswell of grassroots, bipartisan opposition to this, in all types of communities across the US," said Wurth. "Everyone is affected by this, the opposition has been across the political spectrum. A lot of people don't see the benefits coming from AI and feel they will be paying for it with their energy bills and water." "It's an important talking point. We've seen outrageous utility price rises across the country and we are going to lean into this. Prices are going up across the board and this is something Americans really do care about."

  • Taiwan Cries Censorship As Government Bans Rednote
    by BeauHD on 09/12/2025 at 12:30 am

    Longtime Slashdot reader hackingbear writes: Taiwan's government has ordered a one-year block of a popular, mainland Chinese-owned social media app Xiaohongshu, also known as The Little RedNote, citing its failure to cooperate with authorities over fraud-related concerns. Taiwan's Ministry of the Interior on Thursday cited Xiaohongshu's, which does not have business presence on the island, refusal to cooperate with authorities as the basis for the ban, claiming that the platform has been linked to more than 1,700 fraud-related cases that resulted in financial losses of 247.7 million Taiwanese dollars ($7.9 million). "Due to the inability to obtain necessary data in accordance with the law, law enforcement authorities have encountered significant obstacles in investigations, creating a de facto legal vacuum," the ministry said in a statement. Chinese Nationalist Party (KMT), Taiwan's opposition party, Chairwoman Cheng Li-wun decried the government plan to suspend access to Chinese social media platform Xiaohongshu for one year as censorship. "Many people online are already asking 'How to climb over the firewall to access Xiaohongshu,'" Cheng posted on social media. Meta was facing fines earlier this year for failing to disclose information on individuals who funded advertisements on its social media platforms, marking the second such penalty in Taiwan for violating the anti-fraud act. "Meta failed to fully disclose information regarding who paid for the advertisement and who benefited from it," Depute Minister Lin of Ministry of Digital Affairs said at a news conference on June 18. If MODA decides to impose the fine, it would mark the second such penalty against Meta in Taiwan, following a NT$1 million ($33,381) fine issued in May for violating the Fraud Crime Hazard Prevention Act by failing to disclose information on individuals who commissioned and funded two Facebook advertisements. Meta's Threads were also included in the regulatory framework following nearly 1,900 fraud-related reports associated with the platform, with 718 confirmed as scams. Xiaohongshu has surged in popularity among young Taiwanese in recent years, amassing 3 million users in the island of 23 million. Read more of this story at Slashdot.
