  • Former Google CEO Eric Schmidt Booed During Graduation Speech About AI
    by EditorDavid on 17/05/2026 at 11:46 pm

    Today former Google CEO Eric Schmidt "was booed multiple times," reports NBC News, "while discussing AI during a commencement speech at the University of Arizona." Schmidt had started by remembering how computer platforms "gave everyone a voice" but also "degraded the public square... They rewarded outrage. They amplified our worst instincts. They coarsen the way we speak to each other, and that way, and in the way that we treat each other, is in the essence of a society." But then Schmidt "drew a parallel between artificial intelligence and the transformative impact of the computer — and was immediately met with boos." "I know what many of you are feeling about that. I can hear you," Schmidt said, addressing the crowd as many continued to boo him. "There is a fear ... there is a fear in your generation that the future has already been written, that the machines are coming, that the jobs are evaporating, that the climate is breaking, that politics is fractured, and that you are inheriting a mess that you did not create, and I understand that fear." He went on to argue that the future remains unwritten and that the graduating class of 2026 has real power to shape how AI develops — a claim that drew further disapproval from parts of the audience... He closed by congratulating the class and offering them closing words. "The future is not yet finished. It is now your turn to shape it." 404 Media shared a video on YouTube of the crowd's booing — and what Schmidt said that provoked them: SCHMIDT: "If you don't care about science that's okay because AI is going to touch everything else as well. [Very loud booing] Whatever path you choose, AI will become part of how work is done..." "You can now assemble a team of AI agents to help you with the parts that you could never accomplish on your own. [Loud booing] When someone offers you a seat on the rocket ship, you do not ask which seat. You just get on... The rocket ship is here." Read more of this story at Slashdot.

  • Small Town Fights Over Flock's AI-Enhanced Network of License Plate-Reading Cameras
    by EditorDavid on 17/05/2026 at 10:39 pm

    160 miles north of New York City, a man was convicted of manslaughter "with the help of license plate reader technology," reports a local news station. In the small town of Troy (population: 51,000), the mayor described the cameras as "a critical tool" in that investigation. But locals and city officials "have raised concerns about who can access the data collected locally, along with data security, privacy invasions and use by federal authorities, including U.S. Immigration and Customs Enforcement, reports WNYT: When Troy's contract came up for renewal, Mayor Carmella Mantello wanted to keep paying Flock and the council paused payments. The mayor then issued a public safety emergency declaration to keep the license plate readers active. The council has filed a lawsuit to overturn that..."If this illegal emergency order is left unchallenged, we give this mayor and any future mayor regardless of their political party or ideology, unchecked authority to issue an emergency declaration whenever they disagree with the council on any issue," [said Troy council president Sue Steele]. "The technology that's in place today is not the technology of six years ago," council president Steele told another local news station. "We have AI, we have rapidly changing and advancing technology. So that begs the need for regulations to protect certain data." The American Civil Liberties Union warns that Flock will use AI to let law enforcement search its trove of videos. But "Listen, if it was infringing on people's rights, people's liberties, we'd be the first to get rid of it. We have safeguards in place," [mayor] Mantello responded. Mantello noted that data captured by Troy's Flock cameras is only being shared with other local municipalities. Steele said the data had been shared nationally until she and other elected officials raised concerns. "As far as sharing with local law enforcement, that's necessary in the normal course of investigations. The concern is what Flock does with this data: sharing it with ICE, for instance, and other nefarious outlets," Steele said. As the debate continues over the small city's 26 Flock cameras, a columnist in Albany wrote that "it's a good thing. We should be asking questions about the growing surveillance state. We should be debating whether this is the future we want." As the American Civil Liberties Union noted, [Flock] has quietly built a broad mass-surveillance infrastructure, with cameras installed in 5,000 communities around the country, and is continually expanding how that network is used. Did we ask for that? Did we vote for it? Not really. The cameras have been installed in municipality after municipality, mostly with little discussion or controversy, which makes us like the proverbial frogs who didn't notice the water getting warmer until it was boiling. Suddenly, surveillance cameras are everywhere; we're always being watched... [T]he City Council's Democratic majority is considering legislation that, among other steps, would require that data collected by the cameras be generally deleted after 48 hours and that the city be more transparent about how the cameras are used. The controversy and pushback continues to draw local coverage. The mayor complains the proposed rules restricts the cameras "almost exclusively to cases involving individuals with outstanding felony arrest warrants or situations where officers can determine in advance that an incident will result in a felony charge... This is beyond reckless." But the Albany columnist still argues many of America's Flock cameras are unnecessary and are "being installed just because... It's worth considering where this might lead and whether the future we're installing is the future we want." Read more of this story at Slashdot.

  • Microsoft Exchange Server Vulnerability Actively Exploited, in a Bad Week for Microsoft
    by EditorDavid on 17/05/2026 at 8:56 pm

    Forbes describes it as "definitely already out there, and under active exploitation according to the U.S. Cybersecurity and Infrastructure Security Agency, urging all organizations to prioritize timely remediation as the attack vector poses a significant risk." "We have issued CVE-2026-42897 to address a spoofing vulnerability affecting Exchange Outlook Web Access (OWA)," Microsoft told SecurityWeek. "We recommend customers enable EEMS to be better protected, and to follow our guidance available here." Microsoft this week patched 137 vulnerabilities with its Patch Tuesday updates and the cybersecurity industry was surprised to see that the latest updates did not address any zero-days. However, a zero-day was disclosed just 48 hours later, on May 14... described as a spoofing and XSS issue affecting Exchange Server Subscription Edition, 2016, and 2019. "Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Exchange Server allows an unauthorized attacker to perform spoofing over a network," Microsoft said in its advisory. The company noted that the vulnerability affects Exchange Outlook Web Access (OWA) and an attacker can exploit it by sending a specially crafted email to the targeted user. "If the user opens the email in Outlook Web Access and certain interaction conditions are met, arbitrary JavaScript can be executed in the browser context," Microsoft explained. CSO Online shares more details. "Admins should note there are known issues once the mitigation is applied either manually or automatically through the EM Service." - OWA Print Calendar functionality might not work. As a workaround, copy the data or screenshot the calendar you want to print, or use Outlook Desktop client. - Inline images might not display correctly in the recipient's OWA reading pane. As a workaround, send images as email attachments or use Outlook Desktop client... - Admins may get a message saying "Mitigation invalid for this Exchange version." in mitigation details. This issue is cosmetic and the mitigation does apply successfully if the status is shown as "Applied". Microsoft is investigating how to address this glitch. Forbes notes "It's been something of a rough few days for Microsoft Exchange on the security vulnerability front," since this week also saw a zero-day demonstrated at the Pwn2Own Berlin hacking event, "which has been responsibly disclosed and not released into the wild." The Berlin event got off to a flying start on May 14 as Windows 11 was hit by no less than three zero-day exploits. On day two, hacking teams were no less successful, chaining together three new vulnerabilities in Microsoft Exchange in order to achieve the holy grail of SYSTEM-level remote code execution. Such was the level of this achievement that Orange Tsai from the DEVCORE Research Team was rewarded with a $200,000 bounty payment in return for immediately handing over all the technical details to the event organizers. "This is, in fact, good news," Forbes writes, since "full details of the vulnerabilities underlying the exploits, along with the technical nature of the exploit code itself, will be handed over to Microsoft, which will then have 90 days to provide a fix before any details are made public."

  • 'We Still Can't See Dark Matter. But What If We Can Hear It?'
    by EditorDavid on 17/05/2026 at 7:09 pm

    "We may have accidentally detected dark matter back in 2019," writes ScienceAlert. "What if instead of trying to see dark matter, scientists attempted to hear it instead?" asks Space.com: New research suggests dark matter could leave a tiny but discernible imprint in the cacophony of ripples in spacetime called "gravitational waves" that ring through the cosmos when two black holes slam together and merge... Fortunately, when it comes to detecting gravitational waves from colliding black holes, humanity's instruments, such as LIGO (Laser Interferometer Gravitational-Wave Observatory), are getting more and more sensitive all the time... Vicente and colleagues searched through data gathered by LIGO and its fellow gravitational wave detectors, KAGRA (Kamioka Gravitational Wave Detector) and Virgo, focusing on 28 of the clearest signals from merging black holes. Of these, 27 appeared to have come from mergers that occurred in the relative vacuum of space. One signal, however, GW190728, first heard on July 19, 2019, and the result of merging binary black holes with a combined mass of 20 times that of the sun and located an estimated 8 billion light-years away, seemed to carry the telltale trace of this merger occurring in a region of dense, "buttery" dark matter. The team behind this research is quick to point out that this can't be considered a positive detection of dark matter, but does say it gives us a hint at what to look for and thus where to direct follow-up investigations... "We know that dark matter is around us. It just has to be dense enough for us to see its effects," said team leader Josu Aurrekoetxea, of the Massachusetts Institute of Technology (MIT) Department of Physics. "Black holes provide a mechanism to enhance this density, which we can now search for by analyzing the gravitational waves emitted when they merge." They published their results this week in the journal Physical Review Letters. Read more of this story at Slashdot.

  • US Math/Reading Scores Continue 13-Year Decline. Researchers Blame Reduced Testing and Social Media
    by EditorDavid on 17/05/2026 at 5:34 pm

    Test scores "are lower than they were a decade ago in school districts across the U.S.," reports Times magazine, citing new data released Wednesday by Stanford researchers. "Reading scores were down roughly 0.6 grades in 2025 compared to 2015, and math scores were down about 0.4 grades. This means that students were 60% of one school year behind where their peers were in reading a decade earlier and 40% of one school year behind in math." But Stanford's announcement notes that America's schools "were in a 'learning recession' for seven years before the COVID-19 pandemic, with student test scores in math and reading on a steady decline since 2013." This reversal ended two decades of progress, according to Sean Reardon, the Professor of Poverty and Inequality at Stanford Graduate School of Education, whose data forms the backbone of the new research... The study reframes the narrative of pandemic-era learning loss, arguing that the crisis of the last few years was an acceleration of a problem that was already underway. "The pandemic was the mudslide that followed seven years of erosion in student achievement," said Professor Tom Kane, faculty director of the Center for Education Policy Research at Harvard University, and a lead author of the report... The study found that the slowdown in learning coincided with two major shifts in American childhood and education policy: the widespread dismantling of test-based accountability systems that defined the No Child Left Behind era and the rise of social media use among young people. Reading scores, in particular, suffered consistently, with the average annual loss in the years just before the pandemic being just as large as the loss during it... Today, 8th-grade reading scores on national assessments are at their lowest point since 1990. Compounding the problem, chronic student absenteeism remains a major obstacle to improving learning. Though down from its pandemic peak, 23 percent of students were chronically absent in the 2024-25 school year, far above the pre-pandemic rate of 15 percent. More context from Time magazine: Reading scores were down roughly 0.6 grades in 2025 compared to 2015, and math scores were down about 0.4 grades. This means that students were 60% of one school year behind where their peers were in reading a decade earlier and 40% of one school year behind in math... "The decline started around the time that social media's use among teens was exploding, and this was also occurring in a number of other countries," says Thomas Kane, one of the authors of the Educational Scorecard report and a professor at Harvard University... [H]e maintains that it is at the core of the decline in reading achievement. He points out that social media use was shown to be heaviest among the lowest achieving students. "Some states and school districts are making progress," notes the Associated Press, "largely by shifting toward phonics-based instruction and providing extra support for struggling readers." And "The picture is also brighter in math. Almost every state in the analysis saw improvements in math test scores from 2022 to 2025." Read more of this story at Slashdot.

  • How Owners of EVs from Bankrupt Fisker Saved Their Cars With an Open Source Nonprofit
    by EditorDavid on 17/05/2026 at 4:34 pm

    An anonymous reader shared this report from Electrek: When Fisker Inc. filed for Chapter 11 bankruptcy in June 2024, it left roughly 11,000 Ocean SUV owners holding the keys to vehicles that cost them anywhere from $40,000 to $70,000 — and that were rapidly losing the software brains that made them work. No more over-the-air updates. No more connected services. No more warranty. The manufacturer was dead. What happened next is one of the most remarkable stories in the history of the electric vehicle industry. Instead of accepting that their cars would become rolling paperweights, Fisker Ocean owners organized, reverse-engineered their vehicles' proprietary software, hacked into CAN bus networks, built open-source tools on GitHub, and effectively stood up a volunteer-run open-sourced car company from the ashes of Fisker... Within months of the bankruptcy filing, thousands of Ocean owners formed the Fisker Owners Association (FOA) — a nonprofit that quickly grew to 4,000 members and began operating as something between a car club, a tech startup, and an independent automaker. The FOA hired independent tech experts who began reverse-engineering Fisker's proprietary software patches. Members taught each other how to flash firmware. They organized bulk purchases of replacement parts — negotiating the price of key fobs down from roughly $1,000 each to a fraction of that through coordinated group buys. They hosted free global key fob pairing events, saving each owner $100 to $250... What started as desperate troubleshooting has evolved into a genuine open-source ecosystem around the Fisker Ocean. On GitHub, a developer named MichaelOE reverse-engineered the API behind Fisker's official "My Fisker" mobile app and built a Home Assistant integration that exposes every cloud API value as a sensor — with all the app's buttons available as Home Assistant controls... [Community members have also been systematically mapping CAN bus files.] The article noes this "is not an isolated incident. Nikola also filed for bankruptcy, leaving its owners in a similar bind. Canoo and Arrival are headed for liquidation auctions..." Consumer advocates are now pushing for structural changes: mandatory software escrow funds that would keep vehicle software running even if the manufacturer disappears, open-source mandates in bankruptcy proceedings, and shared repair data requirements... European automakers, meanwhile, are moving in a different direction entirely — Volkswagen, BMW, Mercedes-Benz, and eight suppliers signed a memorandum in 2025 to develop a shared open-source automotive software platform.... The Fisker Owners Association has proven that a dedicated community can keep orphaned EVs on the road. But they shouldn't have had to... [O]wners shouldn't need to become hackers and parts brokers and quasi-manufacturers just to keep driving the cars they already paid for. Read more of this story at Slashdot.
