  • An STL file describes an object/shape. This needs to be translated into actual print instructions such as move to X/Y position, squirt plastic, move again, etc. This is what a slicer does: It “translates” from a shape to actual print instructions. I’m not sure, but I’ve always assumed that it’s called slicing because it takes the 3D object and creates many vertical slices with print instructions.

    I don’t know about your printer specifically, but I guess it takes Gcode (which is what you get as output from a slicer) like most other printers? I suggest you grab PrusaSlicer as it’s very flexible and supports a lot of different printer defaults. Load your STL in there, slice it, transfer the result to your printer, and you should in theory be good to go.

    Tip: Start with something small.









  • Not only that song, but I remember it from I was a kid, long before hampsterdance existed.

    The original is from Disney’s version of Robin Hood, you know that version with the fox and the other animals. And I am pretty sure that the one that was sped up and used for hampsterdance is the intro song to the Norwegian version of the audiobook, recorded by Øystein Sunde in 1974.








  • It’s important to distinguish between interaction and constraints. Electromagnetic radiation is a connection, in a sense, but it is not functioning as a constrain, I. E. it does not mechanically link the two bodies. While they do have an effect on each other, their interaction with spacetime is still separated.

    Hubble flow is only disrupted if two bodies in a system have a spatial constraint. Radiation does not provide such a constraint. Gravity can, under some circumstances, but it is not considered a rigid constraint in most cases.

    General relativity is weird, I know.



  • One problem with your thought experiment is that it is by its definition not generating infinite energy.

    The way I understand it is that a remote body will tug on a mithril wire which turns a generator as it unspools. Alright, fair enough for a thought experiment on it’s own, but without any reciprocating action, infinite energy would require an infinitely large spool to unwind.

    Another problem is that the laws of cosmic expansion affects the wire itself. There would be no tugging force between the two bodies. Connecting the two bodies imposes a constraint on them, disrupting the Hubble flow.


  • Simply put, yes. In the same way subdomains are independent of eachother (for example balls.microsoft.com vs balls.apple.com), communities in different instances are independent of each other, even if they share the same name. That’s because a communitys full designation is, for example !asklemmy@lemmy.world

    As for the multiple mod accounts on different instances, this is often because the mod-log and reports often don’t federate properly, so it is common for mods to sign up an identical account on the instance of a community they moderate.

    When it comes to creating identical communities, first thing you need to ask yourself if you should. Sure, if an identical community exists on a different instance, but it’s dead, it shouldn’t be a problem.
    However, when there’s already an active community, it’s better to join and contribute to that one, as fragmentation isn’t really helping anyone in particular or the fediverse in general.
