  • Density comes into it if we are measuring buoyancy. The weight of the displaced water is equal to the weight of the buoyant object, and the ratio of volume submerged vs above water should give a way to determine density, but I don’t have the precise method in my head right now.

    However assuming all you want is the volume, you simply need to fully submerge the object (by applying enough downward force if its density is too low), and the displaced volume is equal to the objects volume. The displaced water will have to flow to the top of the container, so by measuring the rise in water level and multiplying with the base area of your container you can get it easily.

    Just make sure you don’t accidentally also measure your hand if you’re pushing down the sphere.





  • Well… that would be hard. Maintaining, upgrading and extending a corner of the Internet is my day-job.

    So I guess the minimum would be that some other international communications network takes over and Swiss tertiary education institutes would all like to be connected to that instead of the Internet.

    Then all the multiplayer games I host for my international friend group would also have to support this new stack of protocols, same for my communications channels, most of all chat apps and email. Then I could also move my personal use cases off the Internet.

    Then I could be done with it.

    The real question is why would we ever do that, it sounds insanely costly, and not that much is wrong with IPv4 and IPv6.









  • I don’t think it makes any sense either:

    • Cooling will be large and expensive as hell
    • Getting computers there will be expensive
    • Getting solar cells there will be expensive
    • The radiolink to earthbound networks will be expensive and slow

    The only positive is that the energy will be cheap, and that the computers are safe except from nation state actors and untracked space debris.

    I lean towards this being a narrative for the markets. Space Exploration Technologies Corp. claimed a 370 billion USD total addressable market (TAM) in space enabled solutions, and a 26.5 trillion USD TAM for AI in their S-1 filing before going public. They state within that their goal over time is to launch 100 gigawatts of compute to space each year.

    By making the claim that this would be worthwhile they present themselves as uniquely positioned to profit from this situation. Moreso than other AI compute companies or other rocket launch companies.




  • The only use for machine learning I have is translation software, which was getting pretty good already before the LLM hype. Assuming I’d get that back at the pre-hype levels I’d have zero impact.

    I only use it for checking how it would propose to formulate a sentence in French, but then I write my own anyway. Since it would be weird to pretend that was my level of skill towards the customer. Or sometimes I translate back my wobbly French to see if I went really wrong or ran into some false friends (terms that sound similar among the languages but have different meaning).

    It’s like consulting the Chess Engine for the engine move to me.

    If this software too vanished, then I’d just have to use the online dictionaries even more. And be even slower, but who cares this is only once every few weeks, anyway. Most French speaking Swiss are fine with English in text form too.


  • Yeah it seems to be a feature of the text editor, it already replaced the combination of input characters with the proper singular output character when I used the preview feature.

    For context: The footer of my home instance says that it’s running Lemmy 0.19.20 at the moment, which is the latest stable version. Milan Ihl is good about keeping us up to date.
