    Context, these are cars that contained both Palestinian and Israeli people, that were destroyed by Israel due to the Hannibal Directive.

    the IDF fired on Israeli civilian hostages while they were being driven by Hamas militants into Gaza

    The IDF confirmed this to be true, stating

    it would not be morally sound to investigate these incidents [due to the complexity of the situation]

    TLDR: Israel felt it better to kill their own citizens than to let them be taken hostage.






  • When wind speed doubles, the energy it carries increases eightfold,

    Edit: I’m wrong, see edit below!

    Huh? Kinetic energy increase is square, not cubic.

    KE=1/2 m v^2

    So every doubling of speed should increase the available kinetic energy by 4 times, not 8. 3 times the speed is 9 times the energy. Granted there are probably some efficiency gains in excess of this at the low end, but as a rule that’s just wrong.

    Edit: Cool, I learned something new! I neglected to consider it in terms of power, just thought about kinetic energy.

    So something like: KE = 1/2 m v^2

    = 1/2 ( rho V) v^2

    = 1/2 ( rho A d) (d/t)^2

    = 1/2 rho A d^3 1/t^2

    Where P = KE/t

    Thus:

    P = 1/2 rho A (d/t)^3

    = 1/2 rho A v^3

    Lots of other aspects I’m sure I have wrong, but I see how the cubic came to be.












  • Also work in software, and still tweaking the smart home setup to be as intervention free as possible. The upside of the blinds is that I can leave the house and they automatically close to keep cool. When my morning alarm goes off it opens the top half to let in natural light - I’m a heavy sleeper so this is well worth it for me personally. Still haven’t set up smart switches, but it’s next on the list. Ideally a guest could stay and never even know it’s “smart”.
