  • Venmo Redesign Makes New Users' Posts Friends-Only by Default
    by BeauHD on 22/05/2026 at 5:00 pm

    Venmo is testing a major redesign that will make new users' payment posts viewable by their friends by default instead of being public. The Verge reports: It's a notable update for a platform that has struggled with privacy in the past. In 2021, BuzzFeed News tracked down President Joe Biden's Venmo account and the accounts of people in his inner circle because Venmo, at the time, had no way to keep your Venmo contacts private. It fixed that soon after. As part of the redesign, if you're a new user and you do want your posts to be public (or private just to you), you'll be able to set that as part of the new onboarding flow. You can also change your preference in settings after the fact; an updated screen for sending money will also show if that post is private, visible just to friends, or is visible publicly before you make the transaction.

  • Samsung Chip Workers To Get $340,000 Average Bonus In AI Boom
    by BeauHD on 22/05/2026 at 4:00 pm

    Samsung is reportedly set to pay chip-division workers an average bonus of about $340,000 after reaching a tentative deal with its union, according to Bloomberg (paywalled). The deal ended a standoff that "could have cost the economy as much as 1 trillion won ($658 million) daily, with losses potentially multiplying to 100 trillion won ($68 billion) if in-progress semiconductor wafers were rendered unusable," reports Quartz. From the report: The agreement, subject to a union ratification vote running May 22 through May 27, calls for Samsung to direct 10.5% of operating profit into stock bonuses along with a separate 1.5% cash component, according to Bloomberg. The program runs for 10 years, contingent on the company meeting profit thresholds. One-third of the stock award can be liquidated right away, with the rest parceled out in installments across the next two years, Bloomberg reported. The first payout is expected in early 2027. Not all workers will fare equally. As an illustration, Reuters cited a union source estimating that someone in the memory chip unit earning an 80-million-won base salary could take home roughly 626 million won in total bonuses this year. By comparison, workers at SK Hynix stand to collect upward of 700 million won should their employer post annual profit of 250 trillion won, Reuters calculated. Unlike at Samsung, SK Hynix employees are not limited to stock payouts and may instead opt for cash, Reuters reported. Read more of this story at Slashdot.

  • A Bipartisan Amendment Would End Police License Plate Tracking Nationwide
    by BeauHD on 22/05/2026 at 3:00 pm

    An anonymous reader quotes a report from Wired: US lawmakers plan to introduce an amendment Thursday at a House committee markup hearing that would prohibit any recipient of federal highway funding from using automated license plate readers for any purpose other than tolling -- a sweeping restriction that, if adopted, would bring an immediate end to state and local ALPR programs across the United States. The amendment, obtained first by WIRED, is sponsored by Representative Scott Perry, a Pennsylvania Republican and Freedom Caucus member, and Representative Jesus "Chuy" Garcia, an Illinois progressive whose state has become a flash point in the national fight over ALPR misuse. The House Transportation and Infrastructure Committee will mark up the underlying bill -- a $580 billion, five-year reauthorization of federal surface transportation programs -- at 10 am ET on Thursday. The amendment runs a single sentence: "A recipient of assistance under Title 23, United States Code, may not use automated license plate readers for any purpose other than tolling." The amendment is brief, but its reach would be vast. Title 23 funds roughly a quarter of all public road mileage in the US, including most state and county arteries and many city streets where ALPR cameras are becoming ubiquitous. Conditioning that funding on a ban of the technology would, in practical effect, force any state, county, or municipality that takes federal highway money (essentially all of them) to either remove the cameras or restructure their use around tolling alone. The amendment's cosponsors, Perry and Garcia, represent opposite ends of the House's ideological spectrum but converge on a surveillance concern that has gathered momentum in legislatures and city halls across the US as ALPR networks have quietly become a pervasive layer of American road infrastructure. ALPR cameras -- mounted on poles, overpasses, traffic signals, and police cruisers -- photograph every passing license plate, log times and locations, and feed data into searchable databases shared across agencies and jurisdictions. [...] Privacy advocates have long warned that the aggregation of license plate data amounts to a de facto warrantless tracking system. New York University School of Law's Brennan Center for Justice has documented the integration of ALPR feeds into police data-fusion systems that combine plate data with surveillance and social media monitoring. And the Electronic Frontier Foundation, a digital rights nonprofit, has documented a range of police misuse, including the past targeting of mosques and the disproportionate deployment of the technology in low-income neighborhoods. Earlier this week, 404 Media reviewed FBI procurement records that reveal the agency is seeking up to $36 million for nationwide access to ALPR data, which could let it query vehicle movements across the U.S. and its territories through a commercial database.

  • Steve Wozniak Tells Graduates They All Have 'AI': Actual Intelligence
    by BeauHD on 22/05/2026 at 11:00 am

    While other commencement speeches have been met with boos for hyping up artificial intelligence, Apple cofounder Steve Wozniak reminded college graduates that they already posses "AI" of their own: "actual intelligence." He framed AI as an attempt to duplicate brain-like routines, and encouraged students to "think different" as they enter a workforce being reshaped by automation. Business Insider reports: Steve Wozniak did what other college graduation commencement speakers couldn't this year: earn applause when talking about AI. The Apple cofounder took the stage during Grand Valley State University's graduation ceremony earlier this month. During his speech, Wozniak offered reassurance to new graduates who are entering the workforce at the height of the AI revolution. "It would take too long to go deeply into what I think about AI, but we've been trying to create a brain," Wozniak said. "Is there a way we can duplicate a routine a trillion times and have it work like a brain? AI is one of those attempts." [...] During his commencement address, Wozniak reflected on working at Apple and offered students some advice as they begin their careers. "You should always try to think different," he said. "Don't follow the same steps as a million other people. Think, is there something I can do a little different?" You can watch the clip on YouTube. Read more of this story at Slashdot.

  • At Least 80% Responsibility For Ill Health In Old Age Down to Individual, Study Says
    by BeauHD on 22/05/2026 at 7:00 am

    A new Oxford Longevity Project report argues that individuals bear at least 80% of the responsibility for ill health in old age. "The report (PDF), launched at the Smart Ageing Summit in Oxford last week, argues that individuals have far greater control over their longevity than is commonly understood," reports The Guardian. "The authors call on the government to take legislative action on alcohol comparable to restrictions on smoking." From the report: Living Longer, Better -- the Oxford Longevity Project's first Age-less report -- was co-authored by an interdisciplinary panel of UK-based experts in medicine, physiology, ageing and education policy. It was sponsored by Oxford Healthspan. The report's authors, Sir Christopher Ball, Sir Muir Gray, Dr Paul Ch'en, Leslie Kenny and Prof Denis Noble, present the figure of 80% as a conservative estimate. [...] The claim, however, has been described as simplistic and said to neglect wider arguments about whether people are genuinely in control of individual choices when it comes to issues including poverty, pollution and healthcare access. [...] Ball, however, pointed to research including the Landmark Twins Study, where researchers concluded at least 75% of human lifespan is determined by environmental and modifiable lifestyle factors. He also cited large-scale analysis led by Oxford Population Health using data from nearly 500,000 UK Biobank participants which found that environmental exposures and habits carry far greater weight in premature death and biological ageing than inherited genetics. The report's recommendations include avoiding processed foods, abstaining entirely from alcohol, prioritising sleep, not eating after 6.30pm, and cultivating what it calls "a not-meat mindset." On alcohol, it takes a position more forthright than current government guidance. "Alcohol is toxic, don't drink it," said Ball. "The report bravely says so -- whereas the government is afraid to tell the public the truth." Read more of this story at Slashdot.

  • AT&T Sues California In Bid To Stop Offering Traditional Phone Service
    by BeauHD on 22/05/2026 at 3:30 am

    An anonymous reader quotes a report from Reuters: AT&T on Wednesday filed suit (PDF) against California officials seeking a court order declaring it does not have to continue offering traditional copper wire phone service to new customers as it vowed to spend $19 billion on modern telecom services. California requires the U.S. wireless carrier to spend $1 billion annually to maintain a century-old telephone network that few use, AT&T said, saying the network now serves just 3% of households in AT&T's California territory. AT&T's suit named the California Public Utilities Commission and the state attorney general. AT&T said it is committing to investing $19 billion in California as it works to connect more than 4 million additional households and businesses across California by 2030 and added IP-based networks are far more reliable and efficient. AT&T also Wednesday asked the Federal Communications Commission for permission to discontinue traditional phone service in parts of California where it has faster, more reliable service available. It also filed a petition with the FCC to declare that California's rules that effectively require AT&T to power, repair and sell traditional phone service, even after the FCC has authorized the service to be phased out, are preempted by federal standards. AT&T added that transitioning from copper will save an estimated 300 million kilowatt-hours annually by 2030 or the equivalent of eliminating emissions from 17 million gallons of gasoline. The company added that California has already suffered about 2,000 outages from copper thefts this year and it struggles to find replacement parts. The federal government and virtually all states where AT&T historically offered copper-wire service "have now eliminated outdated regulatory obstacles" allowing AT&T to begin powering down its old network and increasing its investments in modern communication technologies, the company said in its lawsuit filed in U.S. District Court in southern California.
