  • And I have a hard time believing that there isn’t some solid or liquid (or maybe some other exotic state of matter, due to the heat and pressure) inner core way down in there, even if it’s relatively tiny compared to the size of the planet.

    Even if it was entirely made of gas when it formed, surely some materials would have fallen in over the eons that could stay solid/liquid at the pressure/temperature of a gas giant’s core?

    Sure. 25% --> 37% … as long as you (for some arbitrary reason) only consider 8 “places” in the solar system.

    7 of those are planets, but Titan is a moon. If we’re going to include moons, then there’s going to be a whole lot more than 8 “places” in the solar system, so the percentage of places where helicopters can work is going to be greatly reduced. If we get really pedantic and consider any orbiting body in the solar system to be a “place”, then there will be hundreds, thousands of them where helicopters can’t possibly work, once you start tallying up asteroids and comets.

    Also, why does the list include 7 planets, not 8? What? Are you not interested in trying to make a helicopter work on Mercury? That’s quitter talk!


  • That’s just because ZFS’s disc cache shows up as application-used memory, instead of disc cache memory. (Disc cache memory is often reported in system monitor tools as ‘free’ memory, because it can be freed up as soon as you need it. ZFS’s disc cache works the same way, but it’s not reported separately to the OS, so that makes it look like ZFS is using a shitload of RAM.) If it bothers you, you can set a maximum amount of RAM for ZFS to use, and that will clear it up. It will mean that your performance is slightly worse, though, because ZFS won’t be able to use disc caching optimally.
