  • Biercuk said. Over an 80-mile test window, a sensor on the tip of the plane’s wing resulted in an average position estimate within about 620 feet of the true position, and the margin of error didn’t increase with the duration of the flight, he said. The performance was more than 10 times better than the inertial navigation system.

    That is a fascinating technique. I wonder if the accuracy will increase with further development.





  • And in the USA and Canada.

    “I didn’t like the look of the place. It didn’t look like a hospital to me,” she told the BBC from her home in Manitoba.

    That hospital – once the home of a Scottish shipping magnate – would be her home for a month in April 1958, after a judge ordered the then-16-year-old to undergo treatment for “disobedient” behaviour.

    It was there that Ms Ponting became one of thousands of people experimented on as part of the CIA’s top-secret research into mind control. Now, she is one of two named plaintiffs in a class-action lawsuit for Canadian victims of the experiments. On Thursday, a judge denied the Royal Victoria Hospital’s appeal, paving the way for the lawsuit to proceed.


  • Let’s devote the full force of modern technology to create a tool that is designed to answer questions in a convincing way. The answer must seem like an accurate answer, but there is no requirement that it be accurate. The terminology and phrasing of the answer must support the questioner’s apparent position and the overall conversation must believably simulate an interaction with a friendly, or even caring individual.

    Yeah, in a world of lonely people who are desperate for human contact and emotional support and are easily manipulated, this is in retrospect, an obvious recipe for disaster. It’s no wonder we’re seeing things like this and some people even developing a psychosis after extended interactions with chat-bots.




  • The 20-foot-long Ran submersible used pulsed sound waves (advanced multibeam sonar) on the ice to map its features, but because of its subantarctic location, Wåhlin and her team couldn’t communicate with the AUV or track its movements with GPS. After 14 missions—some lasting a couple hours and others stretching longer than a day—Ran mapped around 50 square miles of ice, and the structures imaged were more complex than anyone imagined.

    “The mapping has given us a lot of new data that we need to look at more closely,” Wåhlin said in a press statement. “It is clear that many previous assumptions about melting of glacier undersides are falling short. Current models cannot explain the complex patterns we see. But with this method, we have a better chance of finding the answers.”

    The secret structures are melt patterns in the underside of the ice shelf.

    These surveys were conducted in 2022, and the team returned earlier this year to see what changes to the ice shelf had occurred. That’s when Wåhlin and her team’s worst fears were realized—Ran didn’t emerge at the pre-planned rendezvous point. The team suspects that the AUV either ran aground or became the target of some curious seals.

    Yeah, probe broke under the ice shelf and didn’t come back.

    I have to say, Popular Mechanics has become complete shit with headlines like this. I mean, the article is fine for what it is, a story about a group using and self piloting submersible to study glacial melting from below. But that headline is one of the worst click-bait pieces of shit I’ve ever read.




  • Golden Dome is a pipe dream . It simply not technologically feasible to protect the entire country from incoming missiles.

    You probably have to shoot down missiles during the boost phase, when the warheads are still attached. For SDI, the U.S. was dealing with Soviet liquid-fueled missiles that would boost, or burn, for about four minutes. Well, modern ones burn for less than three—that’s a whole minute that you no longer have. This is actually much worse than it sounds because you’re probably unable to shoot for the first minute or so. Even with modern detectors [that are] much better than [those] we had in the 1980s, you may not see the missile until it rises above the clouds. And once it does, your sensors, your computers, still have to say, “Aha! That is a missile!” And then you have to ensure that you’re not shooting down some ordinary space launch—so the system says, “I see a missile. May I shoot at it, please?” And someone or something has to give the go-ahead. So let’s just say you’ll have a good minute to shoot it down; this means your space-based interceptor has to be right there, ready to go, right? But by the time you’re getting permission to shoot, the satellite that was overhead to do that is now too far away, and so the next satellite has to be coming there. This scales up really, really fast.

    And that’s just one of many issues. I recommend reading the whole piece. It really shows what a joke this whole concept is.

    I suspect that this is really just another way for Trump to hand billions of dollars to his buddies. Just watch. When some company is given a contract for this it’ll be a brand new company that just happens to be owned by former republican operatives or politicians. Needless to say, the company will never be required to produce anything either. They’ll just pay out all those billions to consultants and other newly created companies owned by other GOP operatives.

    Do you mean the Gros Michel banana ? It went commercially extinct in the '60s due to a fungus. So, yeah, probably not coming back. Sadly, the Cavendish banana is also subject to the same fungus so may also get wiped out at some point in the future.

    But Race 4 (also known as TR4 or fusarium wilt), the new version of Panama disease that started affecting crops in the subtropics in the 1980s and wiping them out, has since moved to infect crops in the Vietnam, Laos, Pakistan, India, Mozambique, and Australia. In 2019, Colombia declared a national disaster when it was discovered there. As it inches closer to Latin America, the likelihood of losing the Cavendish increases.





  • I actually find it kind of fascinating. There are loads of people in this thread defending this guy and saying that he’s being victimized by a corrupt system, all the while not noticing that he is a retired cop who spent his career as part of that corrupt system and who almost certainly sent more than a few people to jail for a couple of months on charges as bogus as these seem to be. That sounds like it might be karmic payback to me.

    Personally, I’m just keeping an open mind and suspecting that there is more to the story based on the rather large bail.
