  • The UK Finally Starts Reforming Its 'Computer Misuse Act'
    by EditorDavid on 17/05/2026 at 7:34 am

    Computer Weekly reports on "the long-awaited reform of Britain's outdated Computer Misuse Act of 1990 — which has hamstrung the work of the nation's cyber security professionals and researchers for years." The Computer Misuse Act was passed 35 years ago in response to a high-profile hacking incident involving no less than the King's father, the late Duke of Edinburgh. It defined the offence of unauthorised access to a computer — which has been used successfully in countless cyber crime prosecutions over the years. However, as the cyber security landscape has developed into its current form, this language has become increasingly vague and for some years now, a growing number of bona fide security professionals have been arguing that it potentially criminalises their work because from time to time, they may need to gain covert access to IT systems in the course of legitimate research. Speaking to Computer Weekly in 2025, Belfast-based security consultant Simon Whittaker described how the police showed up at his front door after his research was erroneously implicated in the infamous WannaCry incident of 2017... Sabeen Malik, vice-president for global government affairs and public policy at Rapid7, added: "As AI-driven vulnerability discovery scales, defenders need to run automated scanning, agentic red-teaming, and large-scale vuln research at machine speed — activities the 1990 Computer Misuse Act's broad unauthorised-access provisions were never designed to accommodate, leaving UK researchers exposed to criminal risk for work their adversaries face no equivalent friction performing." The reforms are part of a new bill that's "enhancing the powers available to law enforcement and the security services," according to the article. It points out that the U.K. government also intends "to create a Cyber Crime Risk Order that can be applied to control the behaviour of cyber criminals, and new abilities to search people believed to be concealing evidence on behalf of suspected offenders." It's all part of a proposed bill "designed to make the UK a harder target for hostile foreign states and other dangerous groups to attack." Read more of this story at Slashdot.

  • Amazon Stops Supporting Pre-2013 Kindles Today. Some Owners Turn to Jailbreaking
    by EditorDavid on 17/05/2026 at 3:34 am

    Today Amazon ends support for first- and second-generation versions of Kindles and Kindle Fire tablets, along with the Kindle Touch, the 9.7-inch Kindle DX, and other devices released in 2012 or earlier. Owners can continue reading ebooks that they've already downloaded, and they can also still sideload books using a USB cable (from, for example, Project Gutenberg). And PCMag points out that "There are plenty of e-stores where you can buy DRM-free novels legally, such as ebook.com and Smashwords. If you want to try this process for free, public-domain repositories such as the one at Standard Ebooks are a great place to start." (eBook files can be converted for the Kindle with the open source tool Calibre.) New ebooks can no longer be purchased directly from Amazon. But most of Amazon's affected devices "have not received firmware updates for over a decade," notes the blog OMG Ubuntu, "and most lost on-device access the Kindle Store." Some Kindle owners are taking things even further: You can unlock the firmware of older devices to add extra functionality (custom screensavers, epub support) or run entirely different software. On the hardware hacks side, some choose to turn old Kindles into photo frames or online dashboards. TechCrunch offers some caveats about jailbreaking: This process allows users to install custom fonts, new screensavers, alternative reading apps, and even third-party tools that expand the Kindle's functionality... [I]t's important to note that jailbreaking a Kindle might violate Amazon's terms of service. In many jurisdictions, jailbreaking isn't considered a criminal offense for personal use, but it may become a crime if it involves copyright infringement, illegal software distribution, or the sale of modified devices. Many Kindle owners who opt to jailbreak view it as a method to gain control over a device they purchased that is still functional, rather than being forced to buy a new device. However, jailbreaking is technical and carries risks, including the possibility of rendering the device unusable if something goes wrong. It also isn't possible on every Kindle model or firmware version, so before proceeding, Kindle owners should first spend some time researching if their device is compatible. Alternately, PCMag notes, "If you're feeling particularly virtuous, you can donate your old Kindle to a local library or send it back to Amazon free of charge via its electronic recycling program."

  • Some Datacenters Divert Power from Homes. Will It Drive Homeowners to Solar and Batteries?
    by EditorDavid on 17/05/2026 at 1:34 am

    An anonymous reader shared this report from Electrek: A Nevada utility just told 49,000 Lake Tahoe residents that it's redirecting 75% of their electricity supply to data centers, and they have less than a year to find a new power source. It's one of the starkest examples yet of the AI boom's impact on everyday Americans... NV Energy needs the capacity for data centers being built by Google, Apple, and Microsoft around the Tahoe-Reno Industrial Center east of Reno, according to Fortune... Data centers drove half of all US electricity demand growth last year.... That dynamic — small residential customers losing out to massive industrial electricity buyers — is exactly what's driving the broader shift to distributed solar and storage. When the grid becomes unreliable or unaffordable because of data center demand, the homeowners who have solar panels and a battery in the garage are the ones with options. "The shift is measurable," they argue: Third-party ownership models (leases and power purchase agreements), which still qualify for the [U.S.] commercial investment tax credit through 2027, are projected to grow 25% in 2026 and capture up to 69% of residential installations, up from roughly 45% in 2025. Homeowners aren't waiting for incentives to come back — they're finding new ways to get solar on their roofs... [A] battery that can store cheap solar energy and deploy it during peak hours is increasingly essential. California utility customers alone are adding roughly 8,000 new home batteries per month — about 100 MW of new storage capacity. Municipal programs are accelerating the trend. Ann Arbor, Michigan, recently became the first US city to directly deploy solar and battery systems on 150 homes through its city-owned utility. Vermont's Green Mountain Power is offering home batteries at little to no upfront cost. These programs signal that utilities themselves recognize the value of distributed energy.

  • An Entire Wikipedia That's 100% AI Hallucinations
    by EditorDavid on 16/05/2026 at 10:34 pm

    "Every link leads to an entry that does not exist yet," explains the GitHub page for a Wikipedia-like site called Halupedia. "Until you click it, at which point an LLM pretends it has always existed and writes it for you, in the deadpan register of a 19th-century scholarly press..." Every article is invented on demand. The footnotes are also lies... The hardest problem with an infinite, on-demand encyclopedia is internal contradiction... When the LLM writes an article, it is required to add a context="..." attribute on every <a> it inserts, summarising the future article it is linking to (e.g. context="19th-century clerk who formalized footnote drift, Pellbrick's mentor")... When that target article is later requested for the first time, the worker loads the accumulated hints and injects them into the system prompt as "PRIOR REFERENCES — these are CANON". The LLM is instructed that the encyclopedia is hallucinated and absurd, but it must not contradict itself. Fast Company reports that Halupedia was created by software developer BartÅomiej Strama, who confessed in a Reddit comment that the site came about after a drunk night with a friend. In the week since launch, he says Halupedia has amassed more than 150,000 users." Beyond indulging in silly alternate histories, what's the point of using Halupedia? Strama hinted at one larger purpose in a reply to a donor on his Buy Me a Coffee page: "Your contribution towards polluting LLM training data will surely benefit society!" he wrote. The site is licensed as free software under the GPL-3.0 license. Thanks to long-time Slashdot reader schwit1 for sharing the news. Read more of this story at Slashdot.

  • How I Added an LLM-Based Grammar Checking + TeX Math Import To LibreOffice
    by EditorDavid on 16/05/2026 at 9:34 pm

    Former Microsoft programmer Keith Curtis "wrote and self-published After the Software Wars to explain the caliber of free and open source software," according to his entry on Wikipedia, "and why he believes Linux is technically superior to any proprietary OS." He's also KeithCu (long-time Slashdot reader #925,649), and has written a blog post on "How I added an LLM-based grammar checking + TeX math import to LibreOffice." : At Microsoft, I spent five years working on the text components RichEdit and Quill, and came to understand the "physics" of word processing: the file formats, data structures, and algorithms that provided fast access to text and properties, independent of the length of the file. Selecting one million characters to make them bold took about the same time as changing one character, because of the clever data structures (piece tables) and algorithms in these engines... When I decided to add a real-time AI grammar checker to [LibreOffice plugin] WriterAgent, I knew what I was getting into, but I underestimated the trickery of LibreOffice's UNO. His site shares the surprises he encountered, one by one. (Starting with "the office suite throws a bunch of initialization variables at your constructor. If your Python __init__ method doesn't handle them, the code fails to map the call, the stack misaligns, and the program dies.") There's sentence casing issues, duplicate words, and foreign-language syntax — all culminating in new features for "a LibreOffice extension (Python + UNO) that adds generative AI editing to Writer, Calc, and Draw..." "If you want to try it out, the repo is here... Let's make LibreOffice and the free desktop AI-native!" Read more of this story at Slashdot.

  • The Apple-OpenAI Alliance is Fraying, Setting Up a Possible Legal Fight
    by EditorDavid on 16/05/2026 at 8:34 pm

    Bloomberg reports that Apple's two-year-old partnership with OpenAI "has become strained, according to people familiar with the matter." Bloomberg describes OpenAI as "failing to see the expected benefits from the deal and now preparing possible legal action." OpenAI lawyers are actively working with an outside legal firm on a range of options that could be formally executed in the near future, said the people, who asked not to be identified because the deliberations are private. That could include sending the iPhone maker a notice alleging breach of contract without necessarily filing a full lawsuit at the outset, according to the people... OpenAI believed that the companies' partnership, which wove ChatGPT into Apple software, would coax more users into subscribing to the chatbot. It also expected deeper integration across more Apple apps and prime placement within the Siri assistant. Instead, Apple's use of OpenAI technology across its operating systems remains limited, and features can be hard to find... Apple has had its own concerns about OpenAI, including whether the company does enough to protect user privacy. And a recent push [by OpenAI] to make devices — an effort overseen by former Apple executives — has rankled the iPhone maker. Any legal move by OpenAI likely wouldn't come until after the conclusion of the Musk trial, according to the people. No final decisions have been made, and OpenAI still hopes to resolve its issues with Apple outside of court. The article points out that OpenAI "initially believed the deal could generate billions of dollars per year in subscriptions — something that hasn't come close to happening." An OpenAI executive argues to Bloomberg that from a product perspective Apple hasn't done everything they could, "and worse, they haven't even made an honest effort."
