whitequark: whenever you get this, I have a question for you... https://en.wikipedia.org/wiki/Hydrogen_fluoride lists a refractive index of very nearly unity. Is this A) nonsense, B) referring to the gaseous form, not the liquid, or C) really saying that pure liquid HF is nearly invisible in air?
<galois>
[WIKIPEDIA] Hydrogen fluoride | "Hydrogen fluoride is a chemical compound with the chemical formula HF. This colorless gas or liquid is the principal industrial source of fluorine, often as an aqueous solution called hydrofluoric acid. It is an important feedstock in the preparation of many important compounds including pharmaceuticals..."
<Ellied>
I ask you because someone told me you had some HF.

Ellied: so not sure in general, but "pure liquid HF"? keep in mind that its azeotropic point with water is only ~37%
<Ellied>
oh. is pure liquid HF not a thing, then?
<Ellied>
I recall that e.g. fluoroantimonic acid is generally not prepared with water as a solvent since its hydration is too exothermic, and I think wikipedia says it's generally prepared in anhydrous HF
<mofh>
I mean anhydrous HF *is* a thing, just generally not what one sees.
<Ellied>
ah.
<mofh>
it's much less used, basically
<mofh>
Anyway I'd ask /r/chemistry or something, imho.

whitequark: you have to pick a sufficiently late (but not too late or they will have switched to SP3-c) file from MCC (MCC being the 3-letter analysis centre code for ЛОАЦ ЦУП, Лазерный Операционно-Аналитический Центр - Центр Управления Полётами)
<egg>
earlier MCC emits files that are almost b, but have the version field set to a
<egg>
and the others switch to setting version to b earlier, but then put data in the wrong columns

<✔mbeisen> Now that flipped classrooms are all the rage, maybe we should consider flipped labs in which the grad students sit… https://t.co/gkLLrMb4gV

I am suddenly really glad that I randomly decided to backup my old laptop contents while at ANBO back in July
<mofh>
since it meant I had basically no dataloss when shit got stolen in August, instead of, well, not quite "my entire thesis" levels of bad, but it would've been a pretty big problem.

mofh: yeah that kind of shit makes the news every now and then
