  • Your Brain Can Rewire Itself To Allow True Multitasking
    by BeauHD on 29/07/2026 at 9:00 am

    alternative_right shares a report from ScienceAlert: [I]n a new study published in the Journal of Cognitive Neuroscience, researchers from Georgetown University Medical Center in the U.S. have revealed that we can put certain tasks on autopilot in a way that enables something closer to true multitasking. Driving is the perfect example: When you take your test, your entire mental and physical energy is concentrated on executing the right combinations of movements and thoughts. After a decade behind the wheel, the brain is no longer consciously thinking everything through in great detail. In the new study, the researchers found that after extensive practice, the brain can effectively reroute some tasks around the brain's main computing center -- like a bypass road around a city -- to reduce mental overload and improve multitasking capability. "We have another stepping stone in our understanding of how the brain learns," says neuroscientist Maximilian Riesenhuber, senior author of the study. "The encouraging part is that you really can learn to multitask. There is actually a way to remodel your brain architecture and use other parts of your brain." [...] "Previous studies have shown that parts of the temporal cortex can be activated by particular object categories in experienced observers -- birds, cars, even Pokemon -- but a limitation of all of those studies is that they only looked after people became experts," says psychologist Patrick Cox, first author of the study. "We measure before and after training, so we can see that extensive training essentially put a category-selective area in the temporal lobe that was not there before." The study culminated in a dual-task experiment, in which the participants were asked to identify cars and take on another challenge. The individuals whose brains had offloaded more car-sorting work to the temporal cortex did better at the second task. Read more of this story at Slashdot.

  • Trump Administration Bans New Chinese Humanoid Robots
    by BeauHD on 29/07/2026 at 5:30 am

    The Trump administration has banned newly authorized foreign-made humanoid and four-legged robots, along with power inverters, citing "unacceptable risks" to the country's national security. FCC chairman Brendan Carr said the agency was doing its part "to secure America's critical supply chains." The BBC reports: The FCC has added the items to its Covered List -- a register of goods and services that are deemed a risk to US national security. The ban applies to new foreign-produced advanced robotic devices and power inverters and does not prevent the sale or import of any existing models that had been previously authorized by the FCC. The FCC cited concerns that the use of foreign-made inverters could allow overseas firms to turn them off, steal data, facilitate remote access and surveillance by "foreign government actors, or be otherwise exploited through a cyberattack." It added that the use of robots made outside the US could allow "malign actors to surveil Americans, enhance the capabilities of foreign intelligence services, or to remotely commandeer the robots."

  • Workplaces Look For Cheaper AI As 'Tokenmaxxing' Fades As a Corporate Fad
    by BeauHD on 29/07/2026 at 3:30 am

    An anonymous reader quotes a report from the Associated Press: A corporate fad of "tokenmaxxing" on artificial intelligence technology is hitting its limits as workplaces throwing AI at everything are seeing the costs rise without a similar spike in productivity. What started as tech industry-fueled springtime hype over squeezing as much AI-generated work as possible out of products like OpenAI's ChatGPT and Anthropic's Claude has shifted to a summertime backlash. [...] Just a few months ago, Silicon Valley executives were promoting high token consumption as a signal of high-performing employees. The stereotypical tokenmaxxer was staying up late -- perhaps ignoring their significant other -- while orchestrating an army of 24-hour AI agents performing work on their behalf. [...] The trend boosted revenue for leading AI large language model developers like Anthropic and OpenAI, but it fizzled as it became apparent it wasn't necessarily the best strategy for everyone else. [...] Bain & Company management consultant Jue Wang said many of the big businesses her firm advises have been taking a closer look at returns on their AI investments. "The token cost for them has been doubling, almost every other month," she said. "Let's say $200 per developer per month. Multiply that by 20,000 developers, which is often what we're dealing with at these companies, and that quickly gets you to a number that is not a line item that any general manager has planned for." Sometimes that just means not using the AI equivalent of a sledgehammer to crack a nut. "Not everything needs a Claude Opus 4.6," she said of one of Anthropic's more capable models suited to software engineering or deep research. "And yet you see so many companies, so many users, default to using Opus for everything, including generating emails." That's led to a search for tools that do AI "model routing" -- in which easier queries get automatically sent to cheaper and more efficient AI systems and more complex tasks go to more powerful models. [...] At the same time, those who favor racking up as many tokens as possible are having a field day with new open-source models from Chinese startups like Moonshot's Kimi or Zhipu's GLM, which nearly match the capabilities of top U.S. models at a fraction of the price. "There is some validity to the theory that this could push tokenmaxxing a little bit further," said Raffi Krikorian, the chief technology officer at Mozilla. "But if we look at the industry overall, I think it's realizing that tokenmaxxing is a dumb thing." It's similar, Krikorian said, to how software companies once considered how many lines of code a programmer wrote to be a good metric of productivity. That later fell out of favor. "I think tokenmaxxing is moving through the exact same pattern," he said. "I think this is going to be an interesting blip that we're all going to look back to laugh at in a year."

  • Apple Retires iPhone Upgrade Program For Klarna-Backed Leases
    by BeauHD on 28/07/2026 at 11:00 pm

    Apple has replaced its iPhone Upgrade Program with Apple Upgrade, a Klarna-backed U.S. leasing service covering most iPhones, iPads, Macs, and Apple Watches. MacRumors reports: Apple Upgrade has lower base prices than the iPhone Upgrade Program, with iPhones available starting at $17.99 per month and the Apple Watch available starting at $11.99 per month. Macs can be leased starting at $24.99 per month, and iPads start at $11.99 per month. AppleCare+ is optional and not included in the lease price, with customers also able to opt for AppleCare One. There are 12-month and 24-month leasing options for the iPhone and Apple Watch, along with 24-month and 36-month leasing options for the Mac and iPad. Lease cost varies based on device, and is lower with a device trade-in that's applied on a monthly basis. [...] When leasing an iPhone, customers are required to choose a plan from AT&T, Verizon, or T-Mobile, and prepaid plans are not eligible. iPhones need to be leased with a carrier plan, but the iPhones are unlocked so customers can switch carriers if desired. MVNOs like Mint Mobile or Visible are not supported. At the end of the leasing period, customers can choose to return the device and exit the program, pay off the remaining amount owed on the device with a one-time payment and keep it, or return it and upgrade to a new device with a new lease. The payoff amount is the difference between what was paid during the leasing period and the retail price of the device, minus any remaining trade-in credits. Klarna is not charging a fee for the leasing program, so an iPhone that's $1,099 can be leased and then purchased for $1,099 with no extra cost beyond taxes. As with trade-ins, Apple will send a pre-labeled and prepaid shipping box for device returns or upgrades. If you don't opt to pay the purchase fee at the end of the leasing program, you will not own the device and must return it. Last week, after Bloomberg reported on Apple's upcoming leasing program, 9to5Mac uncovered code in the iOS 27 beta suggesting the company was developing a system that could restrict leased iPhones when customers fall behind on payments. Apple has now told The Verge that the new "Restricted Mode" will not be activated in response to a missed lease payment. What the new system is actually meant for remains unclear.

  • AI-Found Bugs Aren't Proving Any Easier to Exploit Despite the Hype
    by BeauHD on 28/07/2026 at 10:00 pm

    AI-assisted vulnerability discovery has yet to produce the expected surge in real-world attacks: VulnCheck found that only 14 of 1,061 attributed discoveries, or 1.3 percent, had been exploited, which is "almost identical to the rate across all vulnerabilities in VulnCheck's dataset," reports The Register. "That's a far cry from the narrative that frontier AI is dramatically tilting the balance in attackers' favor by churning out instantly weaponizable bugs." The findings suggest AI is currently better at increasing the volume of bugs found than making them easier to weaponize. From the report: The report takes particular aim at Anthropic's much-publicized Project Glasswing, unveiled in April with warnings that AI-assisted vulnerability discovery could allow attackers to hijack systems, disrupt operations, or steal data. Claude Mythos may have identified 23,019 vulnerability candidates, but there's remarkably little public evidence showing what became of most of them. VulnCheck notes that only 126 have been published as CVEs, that just one has been confirmed exploited in the wild, and that Anthropic's public disclosure record has seen little movement since Project Glasswing launched. But that doesn't mean AI-assisted vulnerability research has failed, according to Patrick Garrity, security researcher at VulnCheck. "AI-assisted vulnerability discovery clearly has value for both attackers and defenders," Garrity wrote. "The data does not suggest that AI-discovered vulnerabilities are inherently more likely to be exploited than those found through traditional methods." Instead, he argues, AI is simply helping researchers discover more flaws, giving defenders an opportunity to patch them before criminals get there. Garrity stopped well short of declaring the threat overblown forever, but he did suggest some of the rhetoric has outpaced reality. "The data so far, including Anthropic's own stalled disclosure ledger, suggests that AI-assisted vulnerability discovery and frontier capabilities have been overhyped relative to the evidence available today," he wrote. "That doesn't mean the risk is imaginary. It means the impact has been real but modest." Read more of this story at Slashdot.

  • eBay Reaches $56 Million Settlement With E-Commerce Newsletter Writers It Terrorized In 2019
    by BeauHD on 28/07/2026 at 9:00 pm

    eBay and several former executives have agreed to pay $56 million to Ina and David Steiner, the newsletter writers targeted in a 2019 corporate harassment campaign that involved threats, surveillance attempts, and deliveries of live insects and other disturbing items. The settlement closes the couple's civil case after seven former employees pleaded guilty to criminal charges related to the scheme. TechCrunch reports: Ina and David Steiner, a married couple and the co-authors of EcommerceBytes, inspired the ire of high-level eBay executives after occasionally criticizing the company in their newsletter. In 2019, a plot was concocted to intimidate the couple into halting their negative coverage. Executives used sock puppet social media accounts to harass the couple, while also sending them anonymous threatening letters and bizarre items in the mail -- including live spiders and cockroaches, pornographic magazines, a bloody pig mask, a funereal wreath, and a book about surviving the death of a spouse. According to previously released court documents, a plan that was attempted but never successfully carried out involved affixing a GPS tracking device to the couple's car. Yet another internally broached plan involved sending a "Samoan gang" to the Steiners' home. The settlement this week resolves a 2021 civil case brought by the couple against eBay. The law office representing the Steiners writes that the settlement includes $46.15 million paid to the couple by eBay itself, as well as $2 million from former eBay executive CEO Devin Wenig. Additionally, $500,000 will be paid out to the couple from former eBay executive Wendy Jones, as well as $50,000 from former eBay executive Steve Wymer. Additional funds are being paid to various non-profits. In 2022, seven former eBay employees were criminally charged and pled guilty in relation to the plot, including the company's former security chief, James Baugh -- who was sentenced to nearly five years in prison. Others indicted by the U.S. Department of Justice include David Harville, Brian Gilbert, Stephanie Popp, Stephanie Stockwell, Philip Cooke, and former eBay contractor Veronica Zea.
