  • The First New Subsea Habitat In 40 Years Is About To Launch
    by BeauHD on 08/11/2025 at 3:30 am

    An anonymous reader quotes a report from MIT Technology Review: Vanguard feels and smells like a new RV. It has long, gray banquettes that convert into bunks, a microwave cleverly hidden under a counter, a functional steel sink with a French press and crockery above. A weird little toilet hides behind a curtain. But some clues hint that you can't just fire up Vanguard's engine and roll off the lot. The least subtle is its door, a massive disc of steel complete with a wheel that spins to lock. Once it is sealed and moved to its permanent home beneath the waves of the Florida Keys National Marine Sanctuary early next year, Vanguard will be the world's first new subsea habitat in nearly four decades. Teams of four scientists will live and work on the seabed for a week at a time, entering and leaving the habitat as scuba divers. Their missions could include reef restoration, species surveys, underwater archaeology, or even astronaut training. One of Vanguard's modules, unappetizingly named the "wet porch," has a permanent opening in the floor (a.k.a. a "moon pool") that doesn't flood because Vanguard's air pressure is matched to the water around it.It is this pressurization that makes the habitat so useful. Scuba divers working at its maximum operational depth of 50 meters would typically need to make a lengthy stop on their way back to the surface to avoid decompression sickness. This painful and potentially fatal condition, better known as the bends, develops if divers surface too quickly. A traditional 50-meter dive gives scuba divers only a handful of minutes on the seafloor, and they can make only a couple of such dives a day. With Vanguard's atmosphere at the same pressure as the water, its aquanauts need to decompress only once, at the end of their stay. They can potentially dive for many hours every day. That could unlock all kinds of new science and exploration. Read more of this story at Slashdot.

  • 'Vibe Coding' Named Word of the Year By Collins Dictionary
    by BeauHD on 08/11/2025 at 2:20 am

    Collins Dictionary has named "vibe coding" its 2025 word of the year -- a term coined by Andrej Karpathy for when a user makes an app or website by describing it to AI rather than writing programming code manually. The term, which is confusingly made up of two words, was "one of 10 words on a shortlist to reflect the mood, language and preoccupations of 2025," reports the BBC. From the report: By giving an AI tool a simple description such as "make me a program that schedules my weekly meals", people can use "vibe coding" to make basic apps without any previous programming knowledge. More complicated tools still require skill, but the practice has opened up creating digital platforms to non-coders. As many have discovered, it isn't perfect - with no guarantee the code will actually work or be free of bugs. Alex Beecroft, the Managing Director of Collins, said the term "perfectly captures how language is evolving alongside technology." Other words that made the list include "clanker," "aura farming," "broligarchy," "biohacking," and "coolcation." You can view the full list here. Read more of this story at Slashdot.

  • James D. Watson, Co-Discoverer of the Structure of DNA, Is Dead At 97
    by BeauHD on 08/11/2025 at 1:40 am

    ole_timer shares a report from the New York Times: James D. Watson, who entered the pantheon of science at age 25 when he joined in the discovery of the structure of DNA, one of the most momentous breakthroughs in the history of science, died on Thursday in East Northport, N.Y., on Long Island. He was 97. His death, in a hospice, was confirmed on Friday by his son Duncan, who said Dr. Watson was transferred to the hospice from a hospital this week after being treated there for an infection. Dr. Watson's role in decoding DNA, the genetic blueprint for life, would have been enough to establish him as one of the most important scientists of the 20th century. But he cemented that fame by leading the ambitious Human Genome Project and writing perhaps the most celebrated memoir in science. Read more of this story at Slashdot.

  • 'Nintendo Has Too Many Apps'
    by BeauHD on 08/11/2025 at 1:00 am

    The Verge's Ash Parrish writes: Nintendo has released a new store app on Android and iOS giving users the ability to purchase hardware, accessories, and games for the Switch and Switch 2. When I open my phone and scroll down to the N's, I get a neat, full row dedicated entirely to Nintendo. That's four apps: the Switch app, the music app, the Nintendo Today news app, and now the store. (The tally increases to five if you're a parent using the Switch Parental Controls app.) And it is entirely too much. Nintendo has always been the one company of the big three publishers that does its own thing, and that's worked both for and against it. The company hasn't chased development trends with the same zeal as Microsoft and Sony. That insulates Nintendo when those trends don't pan out, like exorbitant spending on live-service games that fail. But also hurts it when it comes to performance and user experience. Console-native voice chat, for example, has been a standard on other platforms for a long time, but was only offered on a Nintendo console with the Switch 2 this year. With the deployment of these apps, Nintendo is both trying to innovate and playing catch-up with results that feel confusing and overwhelming. Do we really need four distinct apps? That's not to say these apps shouldn't exist; they serve valuable and necessary purposes. But when I look at all the programs I have to manage in my Nintendo life, it just feels like it's too much...

  • You Can't Leave Unless You Buy Something
    by BeauHD on 08/11/2025 at 12:20 am

    An anonymous reader quotes a report from SFGATE: At the Safeway on San Francisco's King Street, you now can't leave the store unless you buy something. The Mission Bay grocery store recently installed new anti-theft measures at the entrance and exit. New gates at the entrance automatically swing open when customers walk in, but they're set to trigger an alarm if someone attempts to back out. And if you walk into Safeway and change your mind about grocery shopping, you might find yourself trapped: Another gate that only opens if you scan your receipt blocks the store's sole exit. During my Monday visit, I purchased a kombucha and went through the check-out line without incident. (No high-tech gates block the exit if you go through the line like normal.) But for journalism's sake, I then headed back into the store to try going out the new gate. While I watched some customers struggle with the new technology, my receipt scanned immediately. The glass doors slid open, and I was free. But if, like this person on the San Francisco subreddit recounted, I hadn't bought anything, my only means of exit would have been to beg the security guard to let me out.

  • Texas Sues Roblox For Allegedly Failing To Protect Children On Its Platform
    by BeauHD on 07/11/2025 at 11:40 pm

    Texas is suing Roblox, alleging the company misled parents about safety, ignored online-protection laws, and allowed an environment where predators could target children. Texas AG Ken Paxton said the online game platform is "putting pixel pedophiles and profits over the safety of Texas children," alleging that it is "flagrantly ignoring state and federal online safety laws while deceiving parents about the dangers of its platform." The Verge reports: The lawsuit's examples focus on instances of children who have been abused by predators they met via Roblox, and the activities of groups like 764 which have used online platforms to identify and blackmail victims into sexually explicit acts or self harm. According to the suit, Roblox's parental controls push only began after a number of lawsuits, and a report released last fall by the short seller Hindenburg that said its "in-game research revealed an X-rated pedophile hellscape, exposing children to grooming, pornography, violent content and extremely abusive speech." Eric Porterfield, Senior Director of Policy Communications at Roblox, said in a statement: "We are disappointed that, rather than working collaboratively with Roblox on this industry-wide challenge and seeking real solutions, the AG has chosen to file a lawsuit based on misrepresentations and sensationalized claims." He added, "We have introduced over 145 safety measures on the platform this year alone." Read more of this story at Slashdot.
