    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.


  • One of Sir Issac Newton’s famous phrases is

    “If I have seen further it is by standing on the shoulders of Giants”

    This sounds very nobal and humbling. However, its meaning totally changes with a few facts. It was written in an open letter to Robert Hooke. Hooke was apparently quite short, and EXTREMELY sensitive about this. Newton was basically dissing Hooke. Nobody will be standing on your shoulders, shortie!







  • I’m a parent, and we made the conscious decision to become parents. That said, I can fully understand people who don’t want to have that responsibility. It can be exhausting and thankless, changing almost everything with your life, hobbies and habits.

    On the other side of the coin, the depth of love you feel as a parent is impossible to describe. With that comes a set of incredible feelings, watching your children experience, learn and grow.

    Basically, parenthood is almost completely thankless, but I wouldn’t give it up for the world.


  • The best bet is to let your local aviation authority know. They are generally the ones with the actual powers, as well as the knowledge to apply them.

    At least in the UK, the laws cover anything that leaves the ground under an open sky. There are exceptions for RC toys and drones, but they have limits. One of the limits is you cannot fly within a certain distance of anyone or anything not under your control.

    Basically, most places require your permission to fly over, or near to your land. If they are overflying, they are breaking the rules.

    It’s worth noting, depending on the size of the system, it can be difficult to judge distances. The ones I work with are large. We regularly have officials insisting we are massively out of our flight area. GPS logs show that it was well within the entire time.



  • It very much depends on the task. So long as the tasks don’t overlap, in cognitive requirements, you’re fine. E.g. you can listen to a podcast, while washing up. As soon as the requirements overlap, then your point holds. E.g. I personally can’t write anything down, while listening to an audiobook. The resource requirements overlap.

    It’s also worth noting that different people can do the same task with different parts of the brain. E.g. accurate timekeeping. Some people do it visually, others audibly etc.


  • 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.





  • 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.
