    Your best bet might be to use a laptop as the basis. They are already designed with power efficiency in mind, and you won’t need an external screen and keyboard for local problem solving.

    I would also consider having a raspberry pi 3 or similar as a companion. Services that must be up all the time run on the pi (e.g. network admin). The main computer only gets kicked out of sleep mode when required. The pi 3 needs less power than the newer pis, while still having enough computing power to not lag unless pushed hard.

    I definitely agree with SSDs. HDDs don’t do well when rotated when running. Boats are less than a stable platform.


  • In short, Facebook are incentivised to increase conflict and hate, it improves user engagement. They have also leveraged their large user base to boost numbers in threads significantly. Threads is already a cess pip of bigotry and hate.

    Federating with them would be like connecting your house’s drinking water pipe with the sewage pipe of an industrial pig farm. It would pollute our community to the point of destruction.

    They might try and control this initially. Unfortunately, it would almost certainly be part of an embrace, extend, extinguish attempt. ( https://en.m.wikipedia.org/wiki/Embrace,_extend,_and_extinguish ). They play nice till they have control of enough communities, then they stop the controls, to increase profits.


  • The problem is they fit TOO well. We struggle to get either relativity or QM to deviate significantly close to their “realms”. However, neither predicts the existence of the other, and are incompatible in basic ideas about reality.

    Basically, we know they don’t align, but we can’t access the middle area, and we can’t find any useful cracks to pry at within the accessible areas. It’s been driving physicists up the wall for decades.


  • What’s really screwy is you can force light to only travel as a evanescent wave. It’s completely undetectable without a second interaction, but light must transmit energy using the purely imaginary part of the complex wave.

    The imaginary component definitely has some physical meaning, it’s not just a useful mathematical trick.




  • I think the key difference is that it’s “easier” to apply a meta to a RTS game. In shooters, the meta often involves quick reflex decisions, where to hide, where to shoot etc. This is hard, and requires practice. It also means there is a significant number of players not applying it, or doing so sub-optimally.

    With RTS games, the metas are easier to apply. This means that, in human Vs human games, the newer players often get flattened. It also means that far more complex metas can be developed and applied.

    Shooters tend to back load the difficulty curve. It’s easy to get into them, and not do badly, but hard to do well. RTS games tend to front load the difficulty. You need to get over the initial hump to get “ok” with it. Once over the hump, the curve smooths off and you get good fairly rapidly.

    One of the big differences between nerds and normals is that nerds enjoy punching through that wall. The difficulty is seen as a challenge, not an impediment. Most people want a faster feedback loop on the dopamine reward. FPS type games deliver that extremely well.





  • There will be.

    Colliders work best at specific speeds, like gears on a car. The big collider is fed by a smaller one. That one is likely fed by an even smaller one. Eventually, you get small enough that a simple linear accelerator can get the gas up to speed.

    Oh, and likely a scientist/engineer grinning manically as they “push the trigger” on the largest rail gun in existence.






  • It’s not too bad. Relativity says that no frame of reference is special.

    • On earth, a second looks like a second, but a second on the moon looks too quick.

    • On the moon, the second looks like a second, but a second on earth looks too slow.

    Both are actually correct. The simplest solution is to declare 1 to be the base reference. In this case, the earth second. Any lunar colonies will just have to accept that their second is slightly longer than they think it should be.

    If it helps, the difference is tiny. A second is 6.5x10^-10 seconds longer. This works out to 56 microseconds per 24 hours. It won’t affect much for a long time. About the only thing affected would be a lunar GPS.


  • The worst thing is the advent of AI image generation. Until now, faking a photo took a lot of skilled effort to do well. Holocaust deniers get shot down fairly easily due to the diligent documentation done at the time. One of the generals even ordered it despite protests (it slowed down giving aid). He knew that future generations wouldn’t believe the level we can sink too.

    Now (or in the near future) generating near flawless fakes will be easy. A photograph of a war crime will be no more believable than a scene from an action movie. We’ll likely find work around, but until then, we are in a dead zone on reliability of images.
