Submission + - The people rescuing forgotten knowledge trapped on old floppy disks (bbc.com)

smooth wombat writes: At one point in technology history, floppy disks reigned supreme. Files, pictures, games, everything was put on a floppy disk. But technology doesn't stand still and as time went on disks were replaced by CDs, DVDs, thumb drives, and now cloud storage. Despite these changes, floppy disks are still found in long forgotten corners of businesses or stuffed in boxs in the attic. What is on these disks is anyone's guess, but Cambridge University Library is racing against time to preserve the data. However, lack of hardware and software to read the disks, if they're readable at all, poses unique challenges.

Some of the world's most treasured documents can be found deep in the archives of Cambridge University Library. There are letters from Sir Isaac Newton, notebooks belonging to Charles Darwin, rare Islamic texts and the Nash Papyrus – fragments of a sheet from 200BC containing the Ten Commandments written in Hebrew.

These rare, and often unique, manuscripts are safely stored in climate-controlled environments while staff tenderly care for them to prevent the delicate pages from crumbling and ink from flaking away.

But when the library received 113 boxes of papers and mementoes from the office of physicist Stephen Hawking, it found itself with an unusual challenge. Tucked alongside the letters, photographs and thousands of pages relating to Hawking's work on theoretical physics, were items now not commonly seen in modern offices – floppy disks.

They were the result of Hawking's early adoption of the personal computer, which he was able to use despite having a form of motor neurone disease known as amyotrophic lateral sclerosis, thanks to modifications and software. Locked inside these disks could be all kinds of forgotten information or previously unknown insights into the scientists' life. The archivists' minds boggled.

These disks are now part of a project at Cambridge University Library to rescue hidden knowledge trapped on floppy disks. The Future Nostalgia project reflects a larger trend in the information flooding into archives and libraries around the world.

Submission + - Why GPS fails in cities. And how it was fixed (sciencedaily.com)

alternative_right writes: Our everyday GPS struggles in “urban canyons,” where skyscrapers bounce satellite signals, confusing even advanced navigation systems. NTNU scientists created SmartNav, combining satellite corrections, wave analysis, and Google’s 3D building data for remarkable precision. Their method achieved accuracy within 10 centimeters during testing. The breakthrough could make reliable urban navigation accessible and affordable worldwide.

Submission + - Elon Musk's Satellites Now Constantly Falling Out of the Sky (futurism.com)

fjo3 writes: According to storied Smithsonian astrophysicist Jonathan McDowell, there are now one or two of these Starlink satellites falling back to Earth every single day, he recently told EarthSky. And that figure, McDowell warned, is only going to keep climbing.

The alarming statistic underscores the concerns around rapidly populating the planet’s Low Earth Orbit with expendable satellites. Musk’s SpaceX has been launching thousands of them up there using his reusable rockets since 2019, with more than 8,000 currently in operation.

With those efforts accelerating in recent years, SpaceX has launched more than 2,000 satellites in 2025 alone. Meanwhile, its competitors are rushing to catch up with their own satellite-based internet service, with Amazon kickstarting its plan to deploy more than 3,200 with its first batch launched earlier this year.

Submission + - Scientists seek to turbocharge a natural process that cools the Earth (msn.com)

fjo3 writes: Across vast stretches of farmland in southern Brazil, researchers at a carbon removal company are attempting to accelerate a natural process that normally unfolds over thousands or millions of years.

The company, Terradot, is spreading tons of volcanic rock crushed into a fine dust over land where soybeans, sugar cane and other crops are grown. As rain percolates through the soil, chemical reactions pull carbon from the air and convert it into bicarbonate ions that eventually wash into the ocean, where the carbon remains stored.

The technique, known as “enhanced rock weathering,” is emerging as a promising approach to lock away carbon on a massive scale. Some researchers estimate the method has the potential to sequester billions of tons of carbon, helping slow global climate trends. Other major projects are underway across the globe and have collectively raised over a quarter-billion dollars.

After this long commercial users will have planned for a hardware refresh. Their discards will be a feast far larger than the potential Linux user market (burp!) as always. I consider it a friendly Linux user hardware subsidy.

Home Windows users will amble on as usual. Clueful users (the tiny few who perform their own installs) long ago figured out how to run W11 on unsupported hardware and how to multiboot and/or run VM if they want W10 for something.

W10 VMs run fine on Linux hosts.

Submission + - 'Circular' mega-deals by Bay Area tech giants are raising eyebrows (sfgate.com)

mspohr writes: The deals are so vast that they defy comprehension — the Financial Times put the company’s recent commitments at north of $1 trillion – and they’re making public companies’ stock prices jump. Stock analysts dub some of these agreements “circular,” because investment money is flowing between companies that also buy from or sell to one another. The worry then is that such deals might prop up or overhype a bad business.

Here’s one indicatively tangled pathway through the morass of companies. Nvidia is investing billions in and selling chips to OpenAI, which is also buying chips from and earning stock in AMD. AMD sells processors to Oracle, which is building data centers with OpenAI — which also gets data center work from CoreWeave. And that company is partially owned by, yes, Nvidia. Taken together, it’s a doozy. There are other collaborations and rivalries and many other factors at play, but OpenAI is the many-tentacled octopus in the middle, spinning its achievement of ChatGPT into a blitz of speculative investments.

Submission + - PC sales explode in Q3 as Windows 11 deadlines force millions to upgrade (nerds.xyz)

BrianFagioli writes: IDC says global PC shipments jumped 9.4 percent in Q3 2025, reaching nearly 76 million units. Asia and Japan led the growth thanks to school projects and corporate refreshes tied to Windows 10â(TM)s end of support. North America was the weak link, with tariffs and economic unease keeping buyers on the sidelines even as aging fleets strain under Windows 11 pressure.

Lenovo kept its top spot with 25.5 percent market share, followed by HP at 19.8 and Dell at 13.3. Apple and ASUS both posted double-digit growth. IDCâ(TM)s takeaway is clear: the PC market is not surging on flashy new features, it is being pulled forward by deadlines, old batteries, and the reality that five-year-old laptops do not cut it anymore.

The public (nearly all tech-illiterates, use is not literacy) are easily appealed to by manipulating their emotions which happens to be the purpose of art, secondary even to money laundering.

Artists have easy, low effort jobs and want to keep being paid to churn out kitsch images AI could vomit out at least as effectively at lower cost to the end user. There is nothing left to invent.

Many people cannot compete so they want free money to subsidize their increasingly outdated skills. There is nothing special or admirable about modern "art". That's why art regurgitators want free money to make up for their inability to compete.

Indeed. Most readers won't be ancient enough to remember stenographer pools, mechanical typewriters, and telegrams. They'll have seen video but that cannot convey lived experience. They won't have experienced the transition between manual machine tools and vastly mor capable CNC machining, but we all live in the outcomes.

Post-slop AI (which will take a while and whose improvement will not be uniform) like CNC machine tools will empower imagination like any effective tool. It will also be misused like every other tool because most of humanity are silly and cannot be otherwise.

Submission + - OpenAI bans suspected China-linked accounts for seeking surveillance proposals (reuters.com)

schwit1 writes: OpenAI said on Tuesday it has banned several ChatGPT accounts with suspected links to the Chinese government entities after the users asked for proposals to monitor social media conversations.

In its latest public threat report, OpenAI said some individuals had asked its chatbot to outline social media "listening" tools and other monitoring concepts, violating the startup's national security policy.

The San Francisco-based firm's report raises safety concerns over potential misuse of generative AI amid growing competition between the U.S. and China to shape the technology's development and rules.

OpenAI said it also banned several Chinese-language accounts that used ChatGPT to assist phishing and malware campaigns and asked the model to research additional automation that could be achieved through China's DeepSeek.

The Chinese embassy in the U.S. did not immediately respond to a request for comment on the report.

It also banned accounts tied to suspected Russian-speaking criminal groups that used the chatbot to help develop certain malware, OpenAI said.

Submission + - Black holes might hold the key to a 60-year cosmic mystery (sciencedaily.com)

alternative_right writes: Scientists may have finally uncovered the mystery behind ultra-high-energy cosmic rays — the most powerful particles known in the universe. A team from NTNU suggests that colossal winds from supermassive black holes could be accelerating these particles to unimaginable speeds. These winds, moving at half the speed of light, might not only shape entire galaxies but also fling atomic nuclei across the cosmos with incredible energy.
