@8petros So those 300 participants are always passive/usually passive/...?

@8petros

I don't get what their setup is. They have 300-1000 people sending video to a chat room? If so, who views which of these streams? (I don't think I could fit 300 streams on my screen at more than a thumbnail size.)

@tqbf I think it's a good exercise to consider whether Cramer's Rule is a numerically sound way of solving equations.

@grrrr_shark By persuasion she meant simply steadfastly asking for this concrete thing that you know you want, without any subterfuges or anything. (She stopped using contacts 3(?) years ago, so technically something could have changed?)

@grrrr_shark So, I asked a friend who used to use contact lenses and lives here. She was pretty confused: in her experience you could mail-order contact lenses trivially and physical stores might try to make you take an eye exam, but would relent after a reasonable amount of persuasion.

@grrrr_shark what does LB mean?

@LaF0rge I know little about the setup, so might be very off the mark: have you considered shutting down on (sufficiently long) inactivity? If the device can detect that it's being used and can shut itself down, that should work and might be significantly simpler.

@hollie I started wondering whether it's actually worse on a sailing ship: the ship's center of water resistance shifts forward, so is in a different position vs the center of wind resistance. I don't know how narrow is the acceptable range of the distances between them. If that's important enough, broken rudder would be strictly worse than a stuck rudder.

@leo @whitequark Care to elaborate? I expected the datasheet to give something like the equilibrium RH in presence of unbounded amount of silica as a function of temperature, but i can't find anything like that there.

@x4nw @whitequark

Technically they are _because they're missing alt text_. One might say that that's similar to the jokes being incomprehensible because they are missing an explanation (for some of them the explanation would be be absurdly long, but for some it wouldn't be longer than a typical alt text).

@Ange What do different arrow colors/styles mean? I'm confused by e.g. lack of path from Exif tags to Exif in .jpg that doesn't pass through Tiff.

@LukaszOlejnik That probably won't happen, because it'd ~require Nintendo's approval/help/support, while a Steam Deck is just a reasonably typical x86_64 computer in a weird form factor.

@dunkelstern Hm~ I wonder how related what you want here is from a missing format I see in 3d printing: there we have either shape description (STL or one of the ones based on parametric surfaces), or toolpath description (basically gcode). There's no format that would allow one to specify a shape, with tolerances (e.g. "this surface can be arbitrary as long as it stays between these two provided surfaces") and with printing expectations (e.g. "this has to be at least two extrusions wide"). Currently that lack causes people to have to reverse-engineer e.g. what thickness of a wall will cause it to be formed out of 2 circumferences without a space between them (e.g. from the POV of mechanical strength, width of 2.5 seems worst, because it creates a weird print with a somewhat wider gap between the two lines of extrusion), or what is the shape of an unimportant surface that causes the object to be printable without supports.

@dunkelstern I am thinking of (a) numerically unstable implementations (which, in some parameter regions, amplify floating point inaccuracies ~arbitrarily much) or (b) slightly buggy implementations, rather than simply floating point inaccuracy adding up.

@dunkelstern I don't get how repetitions or calculations have no effect on positioning. If you simulate them inaccurately, you'll end up in a different final position than you'd otherwise, no? Then, given that the usual gcode I've seen contained mostly (only?) relative movement commands, such errors would be applied additively to the rest of the program. Do I misunderstand some part?

@dunkelstern I'm not surprised that's not supported TBH. If controllers support such high-level commands, you end up with multiple codebases (or multiple different implementations of floating point underneath) trying to do the same thing, so much more opportunity for translation bugs (esp. if the computation of position after a command was not trivial from the command's arguments).

Would you want controllers to have that support, or to have _a_ language that has all those higher-level constructs that can be compiled down to g-code?

@dunkelstern Do you mean that gcode interpreters we use don't support instructions that that controller did, and that were useful for hand-writing gcode? If not, I'd appreciate a more verbose version.

Ah, and boosts are very welcome.
