  • When I check out a device in the store I definitely pick it up, hold it, turn it over, and generally look at every part of it. Things like a charging port on the bottom would probably stick out…

    Or like in this case, with the power button on the bottom, I’d definitely notice that as annoying.

    What software do they let you load?

    Basically anything you want, they don’t tend to watch you at the apple store, unless you seem like you actually want to buy something. They want you to mess around with the machines, so I’ve never seen them password protected in any way, you have admin access.






  • What’s amazing about this headline is that it’s clearly inaccurate as they’re confusing causation and correlation, but then at the same time, the correlation itself is completely obvious and hardly worth researching. Of course groups of different demographics behave differently, that’s what the word “demographic” is all about.





  • So to sum up the article, most meteorites (the ones that actually hit earth) are the result of just a few (perhaps three) large asteroid collisions some time in the past.

    Most asteroids seem to be in relatively stable orbits which is basically necessary for them to still be orbiting. So it follows that it would take something altering that orbit for them to end up in an earth intercept course. Ejecta from a collision makes sense.

    I guess the truly surprising part is that most of the samples we have are such good matches that we can conclude they belonged to the same individual asteroids.

    That turns out to not be true, at least not with the tokamak reactors most groups are pursuing.

    You see, at some point you need a shield around the reactor to actually absorb all the high energy particles released, and turn that energy into heat. That’s the whole point of the reactor, to generate heat and run a turbine. You absorb those high energy particles with a “blanket”, that’s just what they call the shield around the reactor.

    Here’s the issue, absorbing all those high energy particles necessarily results in transmuting the material absorbing them. That blanket becomes brittle and eventually needs to be replaced. Not coincidentally, that blanket is also now radioactive, because you’ve bombarded it with protons and neutrons and it’s now partially made up of unstable, radioactive elements.

    So while fission reactors have radioactive fuel rods to dispose of, fusion reactors will have radioactive blankets to dispose of. Who knows if this is an improvement.
