  • John Deere To Pay $99 Million In Monumental Right-To-Repair Settlement
    by BeauHD on 09/04/2026 at 3:30 am

    An anonymous reader quotes a report from The Drive: Farmers have been fighting John Deere for years over the right to repair their equipment, and this week, they finally reached a landmark settlement. While the agricultural manufacturing giant pointed out in a statement that this is no admission of wrongdoing, it agreed to pay $99 million into a fund for farms and individuals who participated in a class action lawsuit. Specifically, that money is available to those involved who paid John Deere's authorized dealers for large equipment repairs from January 2018. This means that plaintiffs will recover somewhere between 26% and 53% of overcharge damages, according to one of the court documents (PDF) -- far beyond the typical amount, which lands between 5% and 15%. The settlement also includes an agreement by Deere to provide "the digital tools required for the maintenance, diagnosis, and repair" of tractors, combines, and other machinery for 10 years. That part is crucial, as farmers previously resorted to hacking their own equipment's software just to get it up and running again. John Deere signed a memorandum of understanding in 2023 that partially addressed those concerns, providing third parties with the technology to diagnose and repair, as long as its intellectual property was safeguarded. Monday's settlement seems to represent a much stronger (and legally binding) step forward. The report notes that a judge's approval of the settlement is still required but likely to happen. John Deere also faces another lawsuit by the U.S. FTC, accusing the company of forcing farmers to use its authorized dealer network and driving up their costs for parts and repairs.

  • 'Survivor' Style Corporate Retreat Descends Into Hellish Nightmare
    by BeauHD on 08/04/2026 at 11:00 pm

    A $500,000 "Survivor"-style corporate retreat for 120 Plex employees in Honduras "turned into a week-long disaster involving illness, wild animals, armed guards, and employees stranded on a remote island," reports the Daily Beast. The CEO was bedridden by E. coli, staff were collapsing in brutal heat during Navy SEAL-led drills, there were fire ant attacks, uncooked food, and failing utilities. At one point, a porcupine even crashed through the ceiling of a guest's room. Here's an excerpt from the report: Tech media company Plex flew its 120 employees to a Honduran resort in 2017 for what was billed as a Survivor-style getaway. They called it "Plexcon." The first harbinger of trouble was an email that arrived before the group departed, informing them that the hotel manager and chef had both quit within days of each other. Things went sharply downhill from there. CEO Keith Valory, 54, had flown out a day early, intending to channel his inner Jeff Probst and welcome his staff off the buses like a game show host. Instead, he spent the arrival morning flat on his back. "I got E. coli, which is maybe the worst thing you could get, possibly, ever," Valory told the Wall Street Journal this week. "Just as people were arriving on the buses, I was like, 'Uh oh.' I lost 8 or 10 pounds. They had a doctor come to me, which apparently is pretty standard. They nailed an IV bag to the bedpost." With the CEO incapacitated, chief product officer and co-founder Scott Olechowski, 52, stepped in to run proceedings -- beginning with a forced eating challenge in which one employee had to consume a dead tarantula. [...] Sean Hoff, 42, founder of Moniker Partners, the independent retreat agency that planned the trip, was running himself ragged attempting damage control -- the showers, water, and electricity kept cutting out. [...] Meanwhile, senior software engineer Rick Phillips, 53, was trying to sleep when he heard a crash in his room. He ignored it until morning. "I got up and went over to get in the shower, and there was a porcupine," he said. "It must have climbed a tree and fallen through the ceiling." Read more of this story at Slashdot.

  • Iran-Linked Hackers Disrupted US Oil, Gas, Water Sites
    by BeauHD on 08/04/2026 at 10:00 pm

    The FBI says (PDF) Iran-linked hackers disrupted internet-connected systems used by U.S. oil, gas, and water companies. Even with the recent two-week ceasefire between Iran and the United States and Israel, hackers backing Tehran say they won't end their retaliatory cyberattacks. The Hill reports: The report warned that similar companies across the country should be aware of an increased push by hackers to take over programmable logic controller (PLC) systems, which can be used to digitally control physical machinery from remote locations. Secure internet access for PLCs from one company, Rockwell Automation, were removed by Iran-linked coders who then "maliciously interacted with project files and altered data," according to the report. Hackers first gained access to some of the platforms in January of last year. All access to compromised platforms ended in March, the report said. The FBI said the move resulted in "operational disruption" and "financial loss." [...] Rockwell Automation wasn't the only company to recently face cyberattacks from Iran-linked hackers. Stryker, a major U.S. medical device maker, was targeted by Iran-affiliated coders in mid-March. It was unclear if physical operations were affected by the security breach. FBI Director Kash Patel was personally impacted by hackers who leaked his emails and records related to his personal travels and business from more than 10 years ago. [...] The FBI urged companies to adopt network defenders and multifactor authentication to prevent future attacks. Tuesday's report was published alongside the National Security Agency, the Department of Energy, and the Cybersecurity and Infrastructure Security Agency. "Government and experts have been warning about internet connected systems for years, and how vulnerable they are," one source familiar with the federal investigation into the hacks told CNN. Many companies have "ealready removed those systems and followed the guidance," the person added. Read more of this story at Slashdot.

  • NYT Claims Adam Back Is Bitcoin Creator Satoshi Nakamoto
    by BeauHD on 08/04/2026 at 9:00 pm

    A New York Times investigation by John Carreyrou claims a British cryptographer named Adam Back is the strongest circumstantial candidate yet for being Satoshi Nakamoto. The report citing overlaps in writing style, ideology, technical background, and old posts that outlined key parts of Bitcoin years before its launch. Carreyrou is a renowned investigative journalist and author, best known for exposing the massive fraud at Theranos while at the Wall Street Journal. Here's an excerpt from the report: ... As anyone steeped in Bitcoin lore will tell you, Satoshi was a master at the art of maintaining anonymity on the internet, leaving few, if any, digital footprints behind. But Satoshi did leave behind a corpus of texts, including a nine-page white paper (PDF) outlining his invention and his many posts on the Bitcointalk forum, an online message board where users gathered to discuss the digital currency's software, economics and philosophy. And that corpus, it turned out, had expanded significantly during the impostor's civil trial when Martti Malmi, a Finnish programmer who collaborated with Satoshi in Bitcoin's early days, released a trove of hundreds of emails he had exchanged with him. Emails Satoshi sent to other early Bitcoin adopters had surfaced before, but none came close in volume to the Malmi dump. If Satoshi was ever going to be found, I was convinced the key lay somewhere in these texts. Then again, others must have gone down this road before me. Journalists, academics and internet sleuths had been trying to identify Satoshi for 16 years. During that span, more than 100 names had been put forward, including those of an Irish cryptography student, an unemployed Japanese American engineer, a South African criminal mastermind and the mathematician portrayed in the movie "A Beautiful Mind." The most alluring theories had focused on coincidences that aligned with what little was known about Satoshi: a particular code-writing style, a mysterious work history, an expertise in Bitcoin's key technical concepts, an anti-government worldview. But they had run aground under the weight of an alibi or some other piece of inconsistent or contrary evidence. Each failure had been met with glee by many members of the Bitcoin community. As they liked to point out, only Satoshi could definitively prove his identity by moving some of his coins. Any evidence short of that would be circumstantial. It seemed foolish to think that I could somehow crack a case that had confounded so many others. But I craved the thrill of a big, challenging story. So I decided to try once more to unmask Bitcoin's mysterious creator. Back, for his part, denies being Satoshi, writing in a post on X: "i'm not satoshi, but I was early in laser focus on the positive societal implications of cryptography, online privacy and electronic cash, hence my ~1992 onwards active interest in applied research on ecash, privacy tech on cypherpunks list which led to hashcash and other ideas."

  • Amazon Is Ending Support For Older Kindles
    by BeauHD on 08/04/2026 at 8:00 pm

    Starting May 20th, Amazon will stop Kindle Store access for Kindle and Kindle Fire devices released in 2012 and earlier. After that date, those devices will "no longer be able to purchase, borrow, or download new content." Owners can still read content already on the device, but if an affected device is reset or deregistered after the cutoff, it can't be re-registered. The Verge reports: The complete list of affected devices goes all the way back to the original Kindle that launched in 2007 with a full keyboard and scroll wheel. [...] Amazon will be notifying affected users over email ahead of May 20th with an explanation of what their older devices can and cannot do. Pre-2012 Kindle Fire devices will be subjected to the same limitations as Kindle e-readers when it comes to books, but other apps and Amazon services on those devices won't be impacted. For longtime users wanting to take the opportunity to upgrade to newer Kindle hardware, Amazon will offer a 20 percent discount on new Kindle devices and a $20 ebook credit that will be added to their accounts after upgrading, valid until June 20th, 2026, at 11:59PM PT. Their older purchases will be available on new devices as long as they log in to the same account they've been using for the past 14 years or more. Read more of this story at Slashdot.

  • Iran Demands Bitcoin For Ships Passing Hormuz During Ceasefire
    by BeauHD on 08/04/2026 at 7:00 pm

    An anonymous reader quotes a report from the Financial Times: Iran will demand that shipping companies pay tolls in cryptocurrency for laden oil tankers passing through the Strait of Hormuz (source paywalled; alternative source), as it seeks to retain control over passage through the key waterway during the two-week ceasefire. Hamid Hosseini, a spokesperson for Iran's Oil, Gas and Petrochemical Products Exporters' Union, told the FT on Wednesday that Iran wanted to collect tolling fees from any tanker passing and to assess each ship. "Iran needs to monitor what goes in and out of the strait to ensure these two weeks aren't used for transferring weapons," said Hosseini, whose industry association works closely with the state. "Everything can pass through, but the procedure will take time for each vessel, and Iran is not in a rush," he added. [...] Hosseini said that each tanker must email authorities about its cargo, after which Iran will inform them of the toll to be paid in digital currencies. He said that the tariff is $1 per barrel of oil, adding that empty tankers can pass freely. "Once the email arrives and Iran completes its assessment, vessels are given a few seconds to pay in Bitcoin, ensuring they can't be traced or confiscated due to sanctions," Hosseini added.
