Some middle-aged guy on the Internet. Seen a lot of it, occasionally regurgitating it, trying to be amusing and informative.

Lurked Digg until v4. Commented on Reddit (same username) until it went full Musk.

Was on kbin.social (dying/dead) and kbin.run (mysteriously vanished). Now here on fedia.io.

Really hoping he hasn’t brought the jinx with him.

  • What does “lift” mean in this context? A web search turns up a Doris Day musical from 1951 which is kind of funny to think about but I’m guessing is not what you mean.

    As for the general case of modifying the Sun - or any star - in some way, it’s all but certain to need a huge number of resources (or amount of energy, or both), and considering the Sun is on the order of a million times larger than Earth, far more than can be obtained from Earth alone.

    I mean, I’d like to be proven wrong and there’s some exotic-physics way of causing the helium in the Sun to spontaneously turn back into hydrogen, but if that was easy, you’d expect that we’d see stars do that by themselves occasionally. We don’t, which implies there would still need to be some kind of energy input required to get it started.

    Without exotic physics, we’d pretty much need on the order of the energy that the star had output from birth up to that point, and if we had that, we’d be better off using that energy in other ways.

    We could get all Earth life off Earth and into a self-sustaining, space-faring habitat with a minuscule fraction of the resources. We might be better off aiming for something like that.


  • The gravitational collapse of a cloud of mostly hydrogen in the vacuum of space.

    And anything falling together under gravity was given that kinetic energy from somewhere* and ultimately it can all be traced back to the Big Bang.

    As for where that energy came from, it’s possible we’ll never know. Most organised religions (and no doubt a few disorganised ones) have their theories, of course. You may subscribe to one of these.

    * This is the principle most commonly simplified as “what goes up, must come down”


  • Given that magic eye pictures are basically a certain convolution of a repetitive source image (or random noise) and a depth map, it ought to be possible for an AI, if not a standard procedural algorithm, to at least attempt to “factor out” the source and map from the result image.

    Whether that even counts as seeing and whether this guy’s neural network could do this, or maybe “see” in some other way is open to question. But I’m guessing it’s a no.


  • Yeah, that’ll go great when the car is suddenly driving 14 miles down the driveway of the house I lived at as a child - a driveway that is walkable in less than a minute - before entering the garage which is a large house that slightly resembles a place I used to work and has a view over a clock tower that may or may not be larger when you look at it from a different angle and I think I’ll nap in this bed that’s here.

    Now tell me: Where is the car relative to its position when that five-second-long dream sequence began, and will that pedestrian ever walk again?

    “But I did nothing wrong” – the boy who dared challenge Putin’s ideology.

    Look, kid, if you speak out against things Poots says are OK, you’re going to prison, simple as.

    Gotta be a mindless yes-man automaton, or suffer the consequences. Get any idea of independent thought out of your head and consider yourself lucky you weren’t standing near any windows.
