  • Left pedal looks more like a dead pedal to me.

    And as others have said, change in direction is still acceleration. That’s part of Newton’s (apocryphal?) apple story — he witnessed an apple falling, and wondered why the moon doesn’t also fall. His amazing insight is that it does fall (accelerate), it’s just that it falls in such a way that it orbits, rather than hits, the Earth (for timescales relevant to a human).


  • Most of the time that leads to them dying.

    Well, squishing has a 100% chance of them dying. With a toddler and a baby, having them run loose sadly isn’t an option.

    We live in a very mild climate, and there’s under-deck and fence space around our house, in addition to bushes, trees, and underbrush — fairly suitable for a variety of arachnids. It’s not the same as indoors, and survival rate certainly isn’t 100%, but it’s not the death sentence of going from a climate controlled house to below-freezing outdoors.



  • I think large planes “look” like they can’t work because their “relative speed” is really low — that is, their speed relative to their length. We’re used to seeing birds cover tens of lengths per second, whereas a large airliner covers ~1ish per second at takeoff.

    Or not, but this always seemed like a plausible explanation as to why planes look impossible. (Though given that hovering birds don’t look funny, maybe this is a silly observation…).






  • It is “backwards” from some other commands — usually you run copy/rsync/link from source to destination, but with tar the destination (tarball) is specified before the source (directory/files).

    That, and the flags not needing dashes always just throws me for a loop.

    And the icing on the cake is that I don’t use tar for tarring that often, so I lose all muscle memory (untaring a tgz or tar.bz2 is frequent enough that I can usually get that right at least…).
