  • Also, some Architectures have specific machine instructions that Compilers just don’t take advantage of, no matter what flags you enable.

    Interesting. Do you have some examples?

    Writing those frequently-called leaf functions in assembly has certainly far outlived it’s use in other places. But, the word on the street, or I guess the conventional wisdom, is that compilers have gradually caught up even there.






  • To give them some credit, Americans know basic facts about their own geography, at least. Washington ends up with roughly the same favourability as Oregon here, and the two states do seem awfully similar.

    Now, knowing that DC is actually full of ordinary, mostly black people, or that Montana isn’t very different from North Dakota? Maybe not. That’s beyond just map facts.


  • Generators, batteries, just a better grid. If it happened tomorrow it would be scary, but it will be gradual. Really poor people in vulnerable areas might not have the option to adapt, which I mentioned, but the average Lemming does.

    Is dying your retirement plan or something? I’m not the one contradicting the experts here.


  • In classical statistical theory, manipulating a probabilistic state is equivalent to picking a single initial state with whatever probability, and then manipulating it. In quantum statistics it’s provably not (at least if we’re measuring particles with as much free will as we think); you need the whole thing for it to make sense. Two likely trajectories can interfere and cancel out, for example.

    So, sure, a position is a vector. But we can only meaningfully talk about functions from a (measurable) set of vectors to their probability amplitude (which is like a probability, but complex). Or, in practice, the infinitesimal density of probability amplitude at that given point

    The uncertainty principal is just one manifestation of that. And, like in the uncertainty principal, entanglement might not stay confined to just position if there’s other parameters, so you really have to talk about functions on the whole state vector. I can’t speak too much to quantum field theory, but the actual dynamics of basic quantum physics is about (very “basic”) functions on those functions.
