  • Motorola Sues Social Media Platforms and Creators in India
    by EditorDavid on 19/04/2026 at 5:34 pm

    "Motorola has filed a lawsuit in India against social media platforms and content creators," reports TechCrunch, "over posts it alleges are defamatory..." The lawsuit, filed in a Bengaluru court and obtained by TechCrunch, names platforms such as X, YouTube, and Instagram along with dozens of content creators, and seeks takedown of the content as well as broader restraint on what it describes as false or defamatory material related to the company's devices. In its over 60-page filing, Motorola has sought a permanent injunction restraining the defendants from publishing or sharing what it describes as false or defamatory content about its products, including reviews, videos, comments, and boycott campaigns. The complaint cites hundreds of posts across platforms, including videos alleging device issues and phones catching fire. But it is also targeting unfavorable product reviews and user commentary that the company alleges are false or defamatory. In a statement after publication, a Motorola spokesperson said it had initiated legal action "in the interest of public safety" against what it described as demonstrably false claims that its devices had exploded or caught fire. One online creator told TechCrunch "they expect more such legal action in the future, as evolving rules around online content increase liability for creators and platforms — a trend reflected in recently proposed changes to India's IT rules aimed at tightening oversight of online content." A Motorola spokesperson "said the company did not seek to suppress legitimate reviews or criticism and was reviewing the scope of the proceedings, adding that it apologized to creators affected inadvertently."

  • Nevada Police Can Now Track Cellphones Without a Warrant
    by EditorDavid on 19/04/2026 at 4:34 pm

    "Nevada quietly signed an agreement earlier this year with a company that collects location data from cellphones, allowing police to track a device virtually in real time," reports the Associated Press. "All without a warrant." The software from Fog Data Science, adopted this January in Nevada through a Department of Public Safety contract, pulls information from smartphone apps in order to let state investigators identify the location of mobile devices. The state is allowed more than 250 queries a month using the tool, which allows officers to track a device's location over long stretches of time and enables them to see what Fog calls "patterns of life," according to company documents from 2022. It can help them deduce where and when people work and live, with whom they associate and what places they visit, according to privacy experts... Traditionally, police must obtain a warrant from a judge to access cellphone location information — a process that can take days or weeks. And while cellphone users may be aware that they are sharing their location through apps such as Google Maps, critics say few are aware that such information can make its way to police... Other agencies in Nevada have been known to use technology similar to Fog. In 2013, Las Vegas Metropolitan Police Department acquired something known as a cell-site simulator that mimics cellphone towers and can sweep up signals from entire areas to track individuals, with some models capable of intercepting texts and calls. Police have not released detailed information about the technology since then. "Police in other states have said the technology (and its low price tag) has helped expand investigatory capacity," the article adds. But it also points out that Fog Data Science has a web page letting individuals opt out of all their data sets. Read more of this story at Slashdot.

  • HP Will Discontinue 'HP Anyware' Remote Desktop, Trusted Zero Clients
    by EditorDavid on 19/04/2026 at 3:34 pm

    kriston (Slashdot reader #7,886) writes: HP Anyware, the new name of the Teradici PCoIP remote desktop solution that was acquired by HP in 2021, is being discontinued. "Maintenance and support for customers and partners with multi-year terms will continue until 31 October, 2029," a href="https://anyware.hp.com/hp-anyware-end-of-life">according to HP's announcement. But HP is also announcing the planned End of Life for Anyware Trust Center and Trusted Zero Clients, with support now limited to setup and troubleshooting, no new updates or patches, and support ending in a little over six months on October 31, 2026. While for Desktop Access customers — Tera2 Zero Clients and PCoIP Management Console — "the previously announced EOL date remains December 31, 2029," sales have already ended for other customers. HP Anyware renewals are available for purchase through October 31 of 2027, but with a maximum one year term, with support ending October 31, 2028. HP says the decision "enables us to focus our resources on product categories where we can deliver the greatest customer value and drive long-term innovation." Read more of this story at Slashdot.

  • Disney Creates Its Own IMAX for 'Avengers: Doomsday' After Losing Screens to 'Dune: Part 3'
    by EditorDavid on 19/04/2026 at 2:34 pm

    Ahead of December's release of Avengers: Doomsday, Disney has unveiled "Infinity Vision," reports Kotaku, which they describe as "a new theater-going experience that will be certain to transform your pedestrian $15 night out into an exotic $43 one." (Though those prices appear to be estimates...) Disney's announcement calls it "a new certification for premium large format (PLF) theaters," helping ticket-buyers find "a huge screen with the sharpest, clearest color and sound," including laser projection "for superior brightness and clarity ") and "premium audio formats for fully immersive sound". Light on specifics, Disney says they will be certifying premium large format theaters for the Infinity Vision experience, highlighting laser projection and immersive audio quality. The new program will begin in the summer for a theater run of 2019's Avengers: Endgame ahead of Doomsday's holiday release. Now you might be thinking: Giant screen? Booming audio? That sounds an awful lot like IMAX. The most consumer-recognized premium movie-going screen is the coveted throne for big blockbuster events, from Avatar to One Battle After Another. Unfortunately for Doomsday, IMAX screens are already booked for the holiday season by Dune: Part Three, the anticipated return to Arrakis, where Timothée Chalamet's Muad'Dib will begin to go worm-mode. Locked out of the popular choice for doubling your ticket price, Disney appears to have made up a new one... Disney says they aim to certify 75 theaters in the United States and 300 internationally for the Infinity Vision program. Read more of this story at Slashdot.

  • Can the 'Attention Liberation Movement' Foment a Rebellion Against Screens?
    by EditorDavid on 19/04/2026 at 11:34 am

    The Associated Press looks at the small-but-growing "rebellion" against attention-hogging devices, citing "a growing body of literature calling for people to move away from screens and pay attention to life." D. Graham Burnett is a historian of science at Princeton University and one of the authors of " Attensity! A Manifesto of the Attention Liberation Movement," making him a pillar of the growing backlash against the corporate harvesting of human attention. Along with MS NOW host Chris Hayes' bestselling " The Sirens' Call: How Attention Became the World's Most Endangered Resource," his work is part of a growing body of literature calling for people to move away from screens and pay attention to life. Burnett says the "attention liberation movement" is about throwing off the yoke of time-sucking apps. People "need to rewild their attention. Their attention is the fullness of their relationship to the world".... There are several dozen "attention activism" groups across the United States and Canada, and the movement has also cropped up in Spain, Italy, Croatia, France and England. Burnett said he expects it to spread further. Some examples cited in the article: "More than a dozen millennials gathered in a brownstone apartment in Brooklyn and placed their phones in a metal colander before two hours of reading, drawing and conversation." A few miles away "Nearly 20 people in their 30s stared at their cellphones for a few minutes. Then they set them down and looked at their bared palms for a while. Then those of their neighbors."

  • Remembering Zip Drives - the Trendy Storage Technology of the 1990s
    by EditorDavid on 19/04/2026 at 7:34 am

    Back in the 1990s, floppy disks "had a mere capacity of 1.44MB," remembers XDA Developers, "which would soon become absolutely tiny for the increasingly large pieces of software that would come about." Floppy disks also felt quite fragile, and while we got "superfloppy" formats that were physically larger and had more capacity, those were pretty unwieldy as portable storage. Enter 1994, when a company called Iomega introduced its variant of a "superfloppy", the Zip drive... [T]he initial capacity introduced in 1994 reached a whopping 100MB, which was huge number when put up against the traditional floppy disk. Zip drives also had major performance benefits, with read speeds that could average 1.4MB/s, as opposed to the comparatively sluggish 16kB/s speeds of a traditional floppy disk, as well as a seek time of around 28ms seconds, whereas a floppy disk averaged 200ms. Zip drives weren't quite as fast as desktop HDDs, but for portable storage, this was a huge step forward... [I]n 1998, Iomega introduced the Zip 250 disks, which increased the capacity to 250MB, and, already in the new millennium, we got the Zip 750, which took that further to 750MB... It was an appealing enough proposition that big computer manufacturers like Dell started including a Zip drive in some of their PCs. Even Apple included Zip drives in some of its Power Macintosh models from the mid-to-late 90s. However, things started to shift towards the end of the decade as other portable formats rose to prominence, most notably CDs and USB flash drives. Despite their initial success, it didn't take long for users to start noticing a major drawback of Zip drives: many times, they would just fail. It wasn't necessarily related to age or any particular misuse of the disks, it just happened. It was a big enough phenomenon that it became known as the "click of death", and once it happened, your drive was gone. The problem was estimated by Iomega to affect around 0.5% of Zip drives, but while that sounds like a small number, when you sell products by the thousands, it becomes fairly widespread. It was a big enough issue that, in September 1998, a class action lawsuit was filed against Iomega for the common problems. Some of the complaints in that lawsuit were eventually dismissed by the court of Delaware, but others were not, and once the public became aware of the problems with Zip drives, it was hard for the brand to make a comeback. It didn't help that this happened around the same time as formats such as CDs were becoming more popular... And eventually, USB flash drives became the most popular way to carry data around since they were smaller and offered much faster speeds... Eventually, after seeing its profits plummet by the mid-2000s, Iomega was sold to a company called EMC in 2008, and in 2013, EMC and Lenovo formed a joint venture that took over Iomega's business and removed all of the Iomega branding from its products. The article does note that "as late as 2014, some aviation companies were still using Zip drives to distribute updates for navigation databases." Are there any Slashdot readers who still remember their own Zip drive experiences? Share your memories in the comments of that once-so-trendy storage technology from the 1990s...
