  • Students Around the World are Using AI-Powered Smart Glasses to Cheat on Tests
    by EditorDavid on 28/06/2026 at 4:34 pm

    Students are using AI-powered smart glasses to cheat on tests, reports CNN. "And in East Asia's test-obsessed societies, where a single exam could impact the trajectory of a student's future career and social status, educators are scrambling to get ahead of the problem." Already, countries are stepping up inspections for test-takers. For China's grueling annual college entrance exam earlier this month — which more than 10 million hopefuls take each year — authorities required screening of all glasses. In the United Kingdom, the head of England's exam watchdog warned earlier this month that AI glasses and smart devices like earpieces could worsen cheating in exams... [T]wo incidents in South Korea were the country's first reported cases of cheating with AI glasses... In Taiwan, the university where a prospective student was caught cheating is now reviewing rules and standard operating procedures for AI eyewears during examinations. But experts worry these individual cases point to a more widespread issue. "If we're seeing a few cases being reported, we're seeing a lot more cases not being reported," said Thomas Corbin, lecturer at Deakin University in Australia, who has conducted research around the usage of AI-powered glasses and other smart devices in academic assessment. With the rapid development of AI technology, however, smart glasses are becoming slimmer, less noticeable, while integrating AI models that can operate independently with connectivity, raising concerns not only about exam integrity, but also about broader privacy risks... "Wearable AI is as much of a challenge to exams as ChatGPT was to essays in 2022 and I just don't think there is any real way that we can reliably have exam practices moving forward," Corbin said.

  • 'Supergirl' Movie Criticized for Script, Poor Visual Effects
    by EditorDavid on 28/06/2026 at 3:34 pm

    The Onion joked the new movie Supergirl is about a hero who must single-handedly save the world "after the catastrophic collapse of interest in the genre." Unfortunately, The Hollywood Reporter says the film's reviews "range from negative to tepid praise (averaging a 58 percent Rotten Tomatoes score)." Many point fingers at the film's script, with Variety's line — "a comic-book movie with the worst script I can remember" — going viral... Not to pile on, but there's another recurring gripe from the reviews that stood out: Critics bashed the film as being murky, dark and gray, with poor VFX: "Muddy CG sludge" wrote one. Another said the film was full of "sludgy browns and grays" and "the visual murkiness of the settings makes it hard to follow the already unintelligible action sequences." A third wrote the "VFX is so rough it makes The Flash look like Avatar." Moviegoers increasingly despise murky, dark visuals (often used to hide weak effects), along with obvious CGI and incoherent action. They've seen it so many times they've become allergic. The Bulwark agreesterribly lit, incoherently staged, and just generally weightless and ugly... [I]t's reminiscent of the disaster that was The Flash: It's just very obvious during certain sequences that everyone was in a big green-screen warehouse and the camera was whipping around with the knowledge that everything would be painted in later, so who really gives a crap how anything looks on the day of." They call the movie "a tremendous slog of a film, a real step backwards for the James Gunn-overseen DC Universe of movies and TV shows" that's "neither fun nor exciting" and "feels empty." The film does have one bright spot: Lobo, who is played by Jason Momoa as something like Michael Keaton's Beetlejuice by way of Jason Momoa's Aquaman. He's blustery and cantankerous and saucy and just a little menacing; it's a perfect piece of casting and a really nice performance. Unfortunately, it's the only spark of life in what is otherwise a deeply dour, deeply boring piece of filmmaking... Supergirl is just a misfire on nearly every level, one that lacks the sincerity and fun of last year's reboot of this universe or the comic pathos present in Gunn's Peacemaker series on HBO Max. Reason calls it "dark, depressive, and dull" and "a downer of a movie in nearly every way." It's not fun. It's barely even righteous. It's just miserable. At one point, Supergirl flat-out murders a guy by pushing a giant sword through his neck. Somehow, I suspect even Zack Snyder would be appalled. Time argued fans of last decade's superhero movies "should be demanding more, not less." Though "Will there be rioting in the streets once audiences get some idea of how lousy Supergirl is? Probably not." Read more of this story at Slashdot.

  • Developer AI Token Costs Could Exceed Their Salaries in Two Years
    by EditorDavid on 28/06/2026 at 11:34 am

    "Enterprises may soon be paying as much for their developers' AI token usage as they do for their salaries," writes InfoWorld: According to Gartner, these costs will meet, or even exceed, the typical software engineer's monthly salary within the next two years. This is not only because developers are increasingly adopting generative AI and agentic tools, it reflects a trend toward consumption-based licensing models as vendors balance infrastructure investments with profitability... Gartner senior principal analyst Nitish Tyagi explained that it's important to note that Gartner's prediction is based on a global average salary of $2,000 per month; it doesn't mean AI token usage will exceed all salaries. For instance, in the US, yearly pay rates can be six digits or more. However, that kind of spend is not out of the realm of possibility, Tyagi emphasized. "I have heard scary numbers like 'My developer consumed $20K last month,' or 'A business user consumed $32K'." If these amounts sound shocking, that's the point. "The goal is to alarm the industry about the impact of token cost if it is not governed and controlled," he said... AI coding vendors have yet to deliver "mature, built-in cost optimization capabilities," Tyagi said, and prices will likely only continue to rise as vendors further build out their models while at the same time trying to remain profitable. Thus, enterprises struggle to forecast and control costs, and, because AI is moving so fast, many organizations lack the "maturity and frameworks" to determine ROI, he noted. Agent-driven workflows are difficult to govern, context windows become bloated, budgets are wiped out earlier than anticipated, and token spend becomes hard to justify.... "Without a governed engineering operating model, costs can escalate faster than the productivity gains these tools are designed to deliver," Tyagi said. Read more of this story at Slashdot.

  • An Amazon Seller Says They Were Offered a Way to Bribe an Amazon Employee
    by EditorDavid on 28/06/2026 at 7:34 am

    Jack Nekhala had a business selling on Amazon — and in December he received an unusual offer, reports Bloomberg. A woman said she could bribe an Amazon employee "to help him retrieve $90,000 in funds that the e-commerce giant had frozen after suspending him over an alleged violation of review policy." Hoping to ingratiate himself with the company and restart his business, Nekhala offered to provide evidence, including recorded conversations and screen shots, that he said proved Amazon personnel were peddling inside information and influence. The smoking gun, Nekhala told the representative: information about his seller account. Only certain Amazon employees are supposed to have access to such details, but Nekhala had received them from the woman on WeChat, the Chinese messaging app. Nekhala's experience, which he documented and shared with Bloomberg, provides a rare glimpse into an international black market that has been a persistent scourge of Amazon's online store. On one side are sellers looking for a variety of favors: a competitive edge over their rivals, information on how to boost sales, a way to get themselves unsuspended. On the other are middlemen who lurk on message apps like Telegram, WeChat and WhatsApp offering access to people inside Amazon who can get things done for a price... It's impossible to determine the scope of the illicit activity, but it's an open secret among Amazon sellers and consultants, who are frequently approached on social-media platforms and messaging apps. "The message is always the same: 'I'm going to show you screenshots to prove I have inside access,'" said Chris McCabe, a former Amazon employee who runs a seller consulting firm... In 2020, federal prosecutors exposed an international bribery scheme involving Amazon sellers and employees. The ring allegedly extracted about $100 million in unfair advantages by bribing Amazon employees in Asia to help them sell more products and sabotage their competitors. Five people in the US were convicted and received jail terms or probation. Last year, law enforcement officials in India began investigating more than 20 former Amazon employees suspected of accepting bribes from trucking companies in exchange for routes, according to The Times of India. After Nekhala reported his own experience to Amazon, the representative committed to "do some digging" and to email him instructions on how his evidence could be shared, according to a recording of the conversation. But Nekhala said he never heard back. The employee who leaked his personal information had already been fired for unrelated misconduct, according to Amazon. Amazon told Bloomberg employee involvement was "very rare," and that "We invest heavily in this area and have dedicated teams and systems in place to prevent all types of fraud, including by our own employees."

  • IBM is Getting Ready to Scale Quantum Computing
    by EditorDavid on 28/06/2026 at 4:34 am

    IBM spent a decade "building, testing and improving" quantum computing, reports the Wall Street Journal. "This year, the company is laying the groundwork to turn that technology into a fully-fledged, scalable business from an expensive science project." IBM said last month it plans to form a new independent subsidiary called Anderon, a foundry to produce the silicon wafers needed to make quantum-computing processors. The venture is seeded by a $1 billion investment from the Trump administration and another $1 billion of IBM's own cash. Anderon will give the company a new line of business in selling wafers to other quantum-computing companies. It will also provide a steady stream of wafers to continue developing its own quantum technology, positioning IBM to capture part of what the Boston Consulting Group projects will be a $90 billion to $170 billion market for quantum-computing providers by 2040... The company also plans to spend an additional $9 billion over five years to advance the final stages of its quest to build a quantum-mechanics-powered computer capable and reliable enough for widespread use, a goal known as fault tolerance. That computer, named Starling, is being targeted for 2029. With Anderon, IBM is thinking beyond Starling, or even a more powerful quantum computer planned for 2033.

  • Renewable Energy Just Hit 30% of America's Electricity Generation
    by EditorDavid on 28/06/2026 at 1:34 am

    America generated 10.06% more energy with renewables in the first four months of 2026 than it did in the same period the year before. That's according to new figures from America's Energy Information Administration, cited in this report from Electrek: The growth was led by utility-scale solar (+21.3%), hydropower (+15.7%), small-scale solar In April alone, wind and solar each produced more electricity than US coal plants, while the combination of solar and wind produced 57.0% more electricity than nuclear power. The mix of all renewables, including biomass and geothermal, accounted for 30.0% of total US electrical generation during the first third of 2026 — up from 27.8% a year earlier... EIA reported that, in April, utility-scale solar capacity surpassed wind capacity for the first time (160,208.1 MW vs. 160,100.6 MW). Further, utility-scale battery energy storage capacity increased by 17,703.5 MW, or 58.1%. Nuclear added just 18.4 MW. The combined capacity growth of all utility-scale renewable energy sources for the 12-month period (55,980.3 MW) is two-thirds more (i.e., 67.6%) than that added during the previous 12 months (33,392.0 MW). "EIA projects no new nuclear generating capacity and a net decline of 5,200.5 MW in fossil fuel capacity." Read more of this story at Slashdot.
