So I found this website that lists specific heat capacities for various foods, and while it doesn’t list “snacks”, dry foods values seem to range from 0.3 to 1 cal•g-1•K-1 = 0.0003 to 0.001 Cal•g-1•K-1. Assuming no phase change (i.e., melting) and otherwise temperature-invariant heat capacity, the energy required for heating a 100 g snack from freezer temps (-18 °C) to body temp (37 °C) is 1.65 to 5.5 Cal. More realistically, we can compare to eating an ambient-temp (20 °C) snack; that difference is only 1.1 to 3.8 Cal… in either case, the difference is negligible, generally < 1% of the calorie count of the snack itself.

No, sorry, I don’t know what kind of ass-backwards somersault your windows machine did this time. Your word doc is randomly missing every third paragraph? Too right mate.

I used to be basically intolerant of it but now hate eating non-spicy versions of foods I’ve grown accustomed to. Spicy peppers and hot chili powder have become a crutch for my otherwise mediocre cooking skills.

Homie dats a gas. Or supercritical fluid, which actually is indeed used for “washing” (SC CO2 is used to decaffeinate coffee). However, like others said, surface tension /= cleaning ability. Part of what soap does is increase the effective solubility of things that are not normally soluble.

ornery_chemist@mander.xyzto Programmer Humor@lemmy.ml•Solutions? Where we're going, we don't need solutions.6·1 year agoSo many solver solutions that day, either Z3 or Gauss-Jordan lol. I got a little obsessed about doing it without solvers or (god forbid) manually solving the system and eventually found a relatively simple way to find the intersection with just lines and planes:
- Translate all hailstones and their velocities to a reference frame in which one stone is stationary at 0,0,0 (origin).
- Take another arbitrary hailstone (A) and cross its (rereferenced) velocity and position vectors. This gives the normal vector of a plane containing the origin and the trajectory of A, both of which the thrown stone must intersect. So, the trajectory of the thrown stone lies in that plane somewhere.
- Take two more arbitrary hailstones B and C and find the points and times that they intersect the plane. The thrown stone must strike B and C at those points, so those points are coordinates on the line representing the thrown stone. The velocity of the thrown stone is calculated by dividing the displacement between the two points by the difference of the time points of the intersections.
- Use the velocity of the thrown stone and the time and position info the intersection of B or C to determine the position of the thrown stone at t = 0
- Translate that position and velocity back to the original reference frame.
It’s a suboptimal solution in that it uses 4 hailstones instead of the theoretical minimum of 3, but was a lot easier to wrap my head around. Incidentally, it is not too hard to adapt the above algorithm to not need C (i.e., to use only 3 hailstones) by using line intersections. Such a solution is not much more complicated than what I gave and still has a simple geometric interpretation, but I’ll leave that as an exercise for the reader :)
Oh absolutely, I don’t blame KDE or arch repos lol. I did see that it was a KDE update but somehow didn’t clock the version number. I had it in my head that KDE6 was much farther off.
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 addingnvidia_drm.modeset=1
to my kernel cmdline makes Wayland work (and quite well at that), though Xorg is still laggy.

I think water is rather rare as a coolant these days. Organics (chemical sense not farming sense) like propylene glycol or some kind of glyme aren’t potentially corrosive to metals if spilled, are harder to grow shit in, have lower volatility, and have a higher thermal limit. Maybe also with a little bit of antifouling agent thrown in. My main gripe with them is that if you do spill them, they don’t evaporate and you’re slipping over the floor for the next few days because you missed a spot.
But yeah, air cooling ftw

Yeah, transliterating to an English spelling doesn’t help much.
I think rz is linguistically equivalent to a soft r, so in this case rze would be “ре”, not “ж”. In some areas, rz is pronounced closer to the Czech ř. IIRC, ж transliterates to ż (not to be confused with ź, which is a soft z). The Polish Roman alphabet is very regular and well adapted to the language, representing palatalization and other non-Latin sounds as digraphs in a similar way to Italian or English.
The cyrillicization of Polish was historically done to a limited extent, but carried with it some, shall we say, sociopolitical baggage. There are also some peculiarities to Polish that either don’t exist or have ambiguous transliterations into Cyrillic, such as the Polish nasals ą and ę or ó (historically a long o, but currenly pronouned /u/).

Nonono, you don’t understand, flame wars build character! 'Twere the early aughts that made me the healthy and well adjusted person I am today!
Or at least, that’s what I’d say if what actually happened wasn’t that I became a jaded bastard and if I didn’t think it was just some ploy to drive engagement to let OP feel popular for a moment… in the best case scenario
Don’t worry, I was being 100% facetious! After all, γ is generally believed to have been a hard /g/ in Ancient Greek, which is the version of Greek that “graphic” is based on and is CLEARLY the wrong way to say gif :D
Kinda sorta un-jerking (but not really) for a moment, I don’t think that I’d include the rhotic in your hypothetical pronunciation in NASA and thus would say /neæ.sə/ over /neɚ.sə/. I also don’t palatalize the U in SCUBA (/sku:.bə/, not /sk^(j)u:bə/), but I suspect that’s just a dialectical difference.
Edit: I just saw your NZ lemmy instance name and now I understand the vowel choices. Cheers!
ornery_chemist@mander.xyzto Memes@lemmy.ml•When you hear someone pronounce GIF as 'JIF242·2 years agoWell, you see, the g in gif stands for “graphics” which is ultimately from Greek “γραφικός,” and because this is the 21st century, γ in front of a close front vowel is pronounced as neither /g/ nor /d͡ʒ/ but rather /ʝ/, which is pronounced a bit like English’s y, so in its purest rendition gif is really pronounced “yiff”, which doubles as homage to the online communities that OP frequents.
It doesn’t work as well spoken, though? Pretty sure Police is pronounced something like po-lee-tseh.
Also, I think you might have swapped a police with Police: “Police police, (whom) Police police police, police Police police.”
