  • In grocery stores in many parts of the US at least, it is extremely hard not to find bread in plastic bags. Even the one of 3 near me that has its own bakery puts the bread in a plastic bag, and then in another bag that is paper with a plastic “window”, and the paper part has a PE wax lining for god knows what reason.



  • Nah, reach is a huge advantage. I’m not sure how rapier fencing differs from regulation sabre/epée/foil, but here’s my 2 cents from that perspective:

    Smaller people are not, as a rule, substantially quicker than larger. If you see any difference in your experience, it’s likely a selection bias (shorter people have to be quicker to compete at the same level). The shorter person must enter the strike range of the taller person before the taller person comes within theirs and must be significantly quicker or more skilled to overcome that dead space. If the taller person can maintain a proper distance, gg. Taller people can also lunge farther, giving a wider active range.

    Targeting is a smaller issue than you make it out to be; footwork and maintaining balance, which reposition the core, are at least as important as leaning to dodge, and advantage the taller person (longer legs = more movement range). If the taller person is coming from above as you say, they can just continue their slash (sabre) downward toward that less mobile core, or squat a bit deeper if the arc won’t reach. If instead you were referring to a poke, they’re either already targeting the torso anyway (foil) or whatever body part is most easily reachable (epée; still often torso, but cheeky wrist/arm strikes can be something of an equalizer here), and anyway they are already striking at a range that the shorter person cannot, making a successful counterattack more difficult.

    Besides reach, a height difference is brutal when it comes to sabre fencing; the shorter person is restricted to targeting arms and torso (can’t reach the head easily), so the taller person can anticipate strikes from fewer angles. The taller person can come from any direction and has gravity on their side for own overhead strikes. Those suck to defend against.











  • Didn’t realize this was happening and yay -Syu went brrr and it broke my shit. Probably doesn’t help that I’m running nvidia with linux (endeavouros). Wayland doesn’t work at all (black screen on login with only mouse ptr, wrong resolution), while Xorg is now much less smooth e.g. on the switching desktop animations. Moving windows around and in-window graphics are fine. Some graphical config stuff changed too; I’m still taking inventory.

    I’m also currently playing with nvidia vs nvidia-dkms with different kernels to see if that solves anything.

    EDIT: Looks like that my configuration was failing to set nvidia_drm modeset=1 correctly due to my unfamiliarity with dracut. Manually adding nvidia_drm.modeset=1 to my kernel cmdline makes Wayland work (and quite well at that), though Xorg is still laggy.







  • One thing that helped me intuit the “sidereal” result (4) was to consider what happens as the radius of circle B approaches 0. At least in my mind, it seems pretty clear that A has to undergo at least one rotation.

    That said, I am unsure that I would have caught this as a test-taker. Derek’s videos always have some “trick”, putting me on guard, but in a testing scenario I would have seen the answer for 3 with no answer for 4, marked it down, and moved on quickly.
