  • I think this has existed as an intentional goal for a long time, albeit from another point of view. I’m thinking of like the piracy days of early 2000, then there was talk about how to lock down devices to prevent any sort of copying of media. The discussion sort of died when Spotify came. But I’m worrying that this development will trigger a reemergence of such a goal. As your self built computer will be more and more expensive, a new possibilty may open up to sell prebuilts that are more locked down. Similarly to how Android is moving from a more open device to a locked down one. HDMI forum locking down their protocols. This may become reality for your general purpose computer. Companies controlling compute and media streaming have a similar motive here, if they do set their mind to it to have this as a fully intentional goal… sigh







  • It is described as that, but I have doubts that any “left” tendencies in there is just to make facism more effective. As I remember a pod episode of the head of that party, then he talks about how Marx described workers as alienated cogs in a machine, basically, and that we should use that by controlled sterilization of immigrants turn their offspring into cogs for the swedish industry/society. Sort of. I don’t know if that really could be classified as a continuation of Marxist thought, but sure.


  • I wouldn’t necessarily say it “tells us something about reality”, as the expression goes, but it is useful in describing reality. Like the last statement of waves, which was supposed to be an spaced out exageration, is how much of physics is built. You look at something and wonder how to describe it. Sometimes it make sense to start with a single pulse, wave, or oscillator, which does not solve it completely and so you add more perturbations to it. You do this sort of stuff basically everywhere in physics. Everywhere else, some other correspondence usually appear. In computer science you use hard problems to design cryptos, physics gets stuck at the same problems. String theory uses algebraic geometry and end up with models where the areas they cannot solve is where elliptic curve crypos come from.



  • Not really that simple. Is EM curving space time? Yes. But it does it in a very different way. EM is a force which couples to charges, magnetism, transferred by light. Gravity is a completely different beast. Super weak, but couples to everything. Mass? Yeah. Massless particles (light)? Yeah. The interraction strength itself is not an indication on how it affects the curvature of space (well, EM as a gauge theory is a curvature of a mathematical space, but gravity is one of physical space).

    As far as I know, none of the observed black holes (like in LIGO) have ever observed something that would be a charged black hole, but there is the theoretical formulation of one called a Reissner Nordström black hole. In that formulation you can see how adding charge and mass acts differently. For one thing, EM charge can be negative and positive, but either sign affects the spacetime the same, in a very simple way: the square of the charge appears in the expression. But mass only appears linear. Just as an example of how they play a very different role when it comes to curvature.



  • They had a linux version way back. I do not think it will ever come back. Not in Sweden at least. Either Google will pressure the cartel of banks which develops the eID app to use the dumb Google Play attestation API which prevents it from working even on more open android versions like GrapheneOS, or they will simply find it too convenient to start using that API. Then it’s finished. There is no demand from anyone, as you cannot even run it on any non-Google sanctioned device. There is no competition, but just a cartel of all the biggest banks which develops the single eID app (there is one alternative which works in very few places). It is not looking good.
