  • Commented on Starship bloopers
    Greg Tingey noted: "Belt-&-Road is old-fashioned colonialism + Imperial expansion" Absolutely not. China hasn't taken over the government of any of the Belt and Road countries, nor has it lopped the arms off slave laborers (in those countries) who can't...
  • Commented on Starship bloopers
    re. the physical capability of power armor vs. the human body: I have less problem with this for powered armor, which should be designed to take the pressure off the body so that using the armor is survivable. If memory...
  • Commented on Starship bloopers
    Re. the thermodynamics of power armor and related topics: I always interpreted the armor as a kind of "personal tank", with the question then becoming just how small you could make a functionally useful tank. But mostly, I just interpreted...
  • Commented on Starship bloopers
    Troutwaxer noted: "I'm going to put on a helmet and some armor before making this comment, but the fundamental strategic error of the post 9/11 world was not making an extensive effort to prune back the Saudis" Yup. The rot...
  • Commented on Starship bloopers
    Troutwaxer noted: "That makes sense. I think you've got to be U.S. born and of a certain age to really feel Heinlein in your gut." Not necessarily. I'm Canadian born and still living here, and pushing 60. I first encountered...
  • Commented on Starship bloopers
    Side note on using "comic book" to mean "overly simplistic" or just plain "stupid". If you believe that, you haven't read any comic books (in which I include graphic novels) since, say, 1970. A lot of the newer stuff is...
  • Commented on Starship bloopers
    fwiw, my take on Starship Troopers the movie: perfectly credible first-person shooter of a movie, bearing no resemblance whatsoever to the book, and redeemed from a literary perspective only by the scene with the brain-eating bug-eyed monster. YMMV....
  • Commented on Starship bloopers
    Troutwaxer noted: "I don't know if I'd agree that Heinlein was a right-wing libertarian, at least not as we understand the term today. He obviously believed that adulthood came with responsibilities as well as privileges, which is something modern right-wing...
  • Commented on Starship bloopers
    Fully agree with Charlie, but one point must be emphasized: "The political framework Heinlein dreamed up for his human population—voting rights as a quid pro quo for military (or civilian public) service" As you note, Heinlein made it clear early...
  • Commented on Lying to the ghost in the machine
    On the whole, I've been favorably impressed with GPS vehicle navigation, but you have to keep your brain engaged the whole time. My personal story: While driving to a mountaintop village in Sicily a few years ago, the software kept...
  • Commented on Lying to the ghost in the machine
    David L notes: "I more and more think it's just that we (wet meat) have a decade or five of experiences that our brains sort through to interpret the visual world. And as we wander further off that pile of...

    The link seems to have disappeared. Here it is again, minus angle brackets: https://mapasyst.extension.org/whats-the-difference-between-a-supervised-and-unsupervised-image-classification/ If that disappears, try Googling "What’s the difference between a supervised and unsupervised image classification?" and "Cooperative Extension" [[ You can't just put angle brackets round...
  • Commented on Lying to the ghost in the machine
    Barry notes: "Everything I've read about 'supervised' learning/classification refers to ML techniques with labels for each case. Human involvement is not necessarily involved, and of course it is very expensive." Note that I was referring to the terminology used in...
  • Commented on Lying to the ghost in the machine
    Elderly Cynic notes: "Your example wouldn't help, because it would have correctly classified the trees as non-tank - what made it a Russian tank was the presence of trees." No, what made it a Russian tank was the fact that...

    On a related note: https://www.thelocal.de/20210305/intern-at-german-prison-faces-hefty-bill-after-sending-photo-of-master-key-to-friends/...

    Oops... substitute (1) = binary 1 = true for (!) in the previous comment. I didn't mean to imply "not"....
  • Commented on Lying to the ghost in the machine
    I suspect we're going to need a lot more (and a lot more sophisticated) use of "supervised classification". Short version: That's the term used in remote sensing to describe when humans "supervise" the classification performed by a computer algorithm to...
  • Commented on Submarine coming through!
    Battery life data points: The 11-year-old main battery on our 2008 Prius hybrid was still working at full or near-full potential when we sold it. That is, the battery had not yet begun to degrade sufficiently to affect the fuel...

    whitroth noted: "They don't pay their employees a good wage. Even more fun with "profit extraction" when employees are over in the third world." Minor correction: the people who assemble Apple products aren't Apple employees; they're employees of a manufacturer...

    Speaking of renewable energy, a promising data point: https://earther.gizmodo.com/great-britain-set-a-wind-energy-milestone-1845961853...
  • Commented on Submarine coming through!
    Graydon noted: "It's difficult to find really large examples, because really large examples are subject to financialisation." Not really. The union I belonged to (PSAC, https://en.wikipedia.org/wiki/Public_Service_Alliance_of_Canada) had 200K members. Our sister union, PIPSC had ca. 60K members. Neither was "financialized",...

    re. unions: My one experience with being a union member was 7 years in the federal government, including several as co-chairman of the workplace safety committee at a research institute. My take was that the people who actually gave a...

    Concerning electric vehicles, a data point from Montreal (Quebec): My wife and I live in west suburban Montreal, about 20 km from the periurbs. We have a Prius Prime hybrid, which gets us a little better than 40 km on...
  • Commented on Submarine coming through!
    Thanks for the explanation Nojay. In response to one point: "Since a 'thorium' reactor is in reality a U-233 fission reactor I fail to see how it would have less waste isotopes from fission than a regular PWR or similar...
  • Commented on Submarine coming through!
    Charlie noted: "You can have safe civil nuclear power or cheap civil nuclear power: it's not obvious that you can have both." Honest question: There's been talk about thorium-fueled reactors for decades, with the nominal benefits being that thorium is...

    JBS wondered: "Oh yes, the mythical "pee tape". How much leverage do you think that provides after "grab 'em by the pussy". If it exists, it might provide significant leverage. One thing Trump hates more than anything else is seeming...
  • Commented on Submarine coming through!
    Re. "self-pardoning": Seems unlikely to survive SCOTUS. I'm not a fan of most of their members, but they've already rejected Trump initiatives that they considered to be a threat to the rule of law or just ill-considered*. I won't claim...

    whitroth observed: "Next you're going to tell me that no one should be allowed to make up an acronym first, and decide what it means after. And you're going to say they can't be drinking or smoking while doing it."...
  • Commented on Submarine coming through!
    SFReader: Agreed in principle, but relying on insurance math kinda fails the ethic test, don't you think?...
  • Commented on Submarine coming through!
    mdive noted: "Quantum Teleportation - way too far out of my knowledge to judge." Ditto, but with one quibble: it's not teleportation. Whatever the denotation of the word (the strict etymological meaning), connotation (how words are actually used) outweighs denotation...
