whitequark: actually that can be *very* confusing e.g. between french-speaking switzerland, where they have a sane idea of what engineer means, and france: an engineer chemist in switzerland probably means somebody who knows how to do industrial-scale stuff, an engineer chemist in france might mean someone who had a sword called a tangent during his studies and does lab preparations

<0xabad1dea> This might just finally spur eggs to take the two microseconds to stop being eggs, but who knows the mind of egg https://t.co/4jIl11y1MR
<whitequark>
egg|zzz|egg: "egg" on twitter generally means a an account with seven followers that suddenly appears in your mentions with something like "well actually we should've killed all jews #MAGA"
<whitequark>
because these people often don't bother changing the default avatar. those who do usually crop something from anime, which is just as irritating.
<whitequark>
you could observe them in the wild by opening the replies to any political tweet with >1000 RTs
<Iskierka>
finding an avatar that isn't just anime is hard. eggs work fine
* Iskierka
is considering just saving the default, uploading, and setting as avatar, though
<whitequark>
I use a black square
<whitequark>
works nicely
<bofh>
I use a random shot of YBCO exhibiting the Meissner effect, works well. :P
<bofh>
since all the rest of an Rb frequency reference is either just photodiodes or can be implemented with an Si5351c
<bofh>
basically you just sweep an oscillator around 6834682610.904Hz, feed this RF into the discharge lamp cavity, and then lock the PLL frequency when the light intensity dips slightly, which it will once you hit the Rb-87 hyperfine transition frequency point.
<bofh>
so basically it's just a gas discharge bulb with a C-band RF emitter loop around the cavity
<whitequark>
bofh: ... huh
<egg|zzz|egg>
whitequark: Iskierka: bofh: I just use my face, which is admittedly eggstremely unoriginal
<egg|zzz|egg>
on the KSP fora I used a photo of robin eggs
<egg|zzz|egg>
whitequark: and yeah, I was aware of this use of egg, it's just that since everybody calls me egg around here twitter gets a bit confusing at times :-p
<GreeningGalaxy>
come on, why does trying to change my touchpad driver break the mouse AND keyboard
* GreeningGalaxy
ſtabs X11
<GreeningGalaxy>
under Manjaro if I switched to the evdev driver, something would break and/or work in a way that let me adjust the pointer speed even though it's really sure that it's not a touchpad.
<bofh>
whitequark: oh, that seems to be basically exactly what I need.
<bofh>
like that is moderately pricey but far less than what they actually sell full Rb discharge tubes for...
<bofh>
am I failing at google or are there basically no suppliers for like cheap Rb discharge tubes? I am actually really surprised if that were the case, but I also can't find any.
<GreeningGalaxy>
Rb is pretty rare, isn't it? and hard to contain without having react with stuff.
<whitequark>
GreeningGalaxy: any decent chemical supplier will have it
<whitequark>
unfortunately, they *may* only have it in like, 50 gram quantities
<whitequark>
which is a *lot* of Rb.
<whitequark>
(can you tell I needed it)
<GreeningGalaxy>
heh, you and your over-large quantities of chemicals
<GreeningGalaxy>
why is ionization energy always given in kJ/mol and not, like, eV
<whitequark>
in chemistry it's kJ/mol, in physics it's eV
<bofh>
GreeningGalaxy: so I can get Rb trivially. what I want is someone to have done the work of filling a tube with it, sealing it, attaching electrodes to it, and connecting that to an 80MHz neon sign transformer and a small heater.
<GreeningGalaxy>
although I fully expect there to be a Rubidium (mathematics) page
<GreeningGalaxy>
bofh: ah
<bofh>
like basically a neon tube, except with rubidium.
<GreeningGalaxy>
why a heater?
<bofh>
so, like, gas discharge tube...
* GreeningGalaxy
didn't know GDTs usually needed heaters?
<bofh>
so, Rubidium, at room temperature and about 0.2atm pressure is in what phase?
<GreeningGalaxy>
oh, is it solid?
<bofh>
yep.
<GreeningGalaxy>
also, TIL phosphors don't actually involve any phosphorus at all. My entire life has been a lie.

also, everything sucks: with the window open, it's cool enough in here to sleep, but then pollen blows in and murders my nose; with the window closed, my nose works, but it gets too hot to sleep.
<Iskierka>
sleep in fridge?
<GreeningGalaxy>
someday I want to live in a residence where I get full exclusive control over the thermostat.
<whitequark>
GreeningGalaxy: aircon?
<GreeningGalaxy>
I have an air conditioner... but it seems dumb to put it on when it's 6°C outside.
<GreeningGalaxy>
friggin neighbors want their posh non-basement apartments to be roasty toasty, and I get to live with the furnace.
<whitequark>
why is it dumb?
<whitequark>
expensive, I can understand
<GreeningGalaxy>
maybe this thing has a fan-only mode or something, hmm
<GreeningGalaxy>
although I don't know what kind of filter it has.
<whitequark>
um, no, it won't work for pollen
<whitequark>
you need a HEPA filter for that, and if you open a window that won't help you anyway
<whitequark>
just close the window and turn on the aircon *shrug*
<GreeningGalaxy>
the aircon needs the window, it's one of those portable units
<GreeningGalaxy>
I really get *no* control over the building centrals.
<GreeningGalaxy>
well I mean, I could go in there and pull the breaker, but that wouldn't last long.
<whitequark>
ohhh
<GreeningGalaxy>
the window's too small for a normal window unit, so I have one of the ones that looks like a dehumidifier with a big hose.
<whitequark>
oh lol those
<whitequark>
just give up
<whitequark>
it'll still draw in pollen
<whitequark>
maybe sleep in a respirator.
<GreeningGalaxy>
right now I have the window open but a bedsheet sort of stuffed into it, and it's actually almost working?
<GreeningGalaxy>
like my nose is only sort of dead and the temp in here is reasonable
<whitequark>
personally I would just make a proper air conditioner
<GreeningGalaxy>
yeah but like, you're you.
<whitequark>
come on it's not hard
<whitequark>
do you *want* me to come and make you a proper air conditioner.
<GreeningGalaxy>
that would be awesome actually
<GreeningGalaxy>
but in all seriousness the only equipment I have access to is not geared up for mechanical shenanigans and I have to live for the next three weeks on about $200
<whitequark>
where you at
<GreeningGalaxy>
chicago
<whitequark>
mm
<whitequark>
so I planned to go by chicago next time i'm in the US anyway
<whitequark>
... *and* I have my set of aircon tools with me...
<egg|zzz|egg>
:D
<GreeningGalaxy>
say, why don't you come by around August or so, for the eclipse? Illinois is supposed to have the best view anywhere.
<whitequark>
I thought about that
<egg|zzz|egg>
egglipse!
<whitequark>
but eclipse means every hotel's gonna be booked
<whitequark>
actually I am pretty sure they sold out like a year before the eclipse
<GreeningGalaxy>
I've got a couch, but here is what, 5 hours away from the eclipse path?
<whitequark>
keep in mind i don't have a driver's license
<whitequark>
which is awfully inconvenient in the US
<whitequark>
I've been meaning to rectify that but it's... hard
<whitequark>
also I *really* don't want to deal with DMV just yet because reasons
<GreeningGalaxy>
tzz, me either.

I think one of my profs is going to do a balloon thing for the eclipse, so I assume he's going to drive me down there
<GreeningGalaxy>
or maybe one of the grad students or somebody
<GreeningGalaxy>
I like how cleaning off my desk almost always pays more than minimum wage
<GreeningGalaxy>
spend 20 minutes doing it and find like $10 in change
<GreeningGalaxy>
of course if you actually look at that mechanism holistically, it not only pays far less than minimum wage to wait for coins to accumulate, but there's also the little detail of whose pockets those coins are coming from
<GreeningGalaxy>
but I'm nothing if not occasionally optimistic

cooool. This shitty $3 webcam has a lens made in such a way that you can adjust it to focus pretty much arbitrarily close.

<GreeningGalaxy>
This camera's lens looks like it could be a relative of a hyperboloid. Honestly if I had to guess I'd say they put molten plastic in a cylinder and spun it until it hardened.

UmbralRaptor: I need to run Late, not FashionablyLate
<egg|zzz|egg>
[this probably raises more questions than it answers]
<UmbralRaptor>
Pretty much.
<egg|zzz|egg>
I think I should document what I know of the KSP APIs at some point
<egg|zzz|egg>
probably as an epic written in Akkadian cuneiform
<UmbralRaptor>
You'll mail us a box of clay tablets on request, right?
<egg|zzz|egg>
whitequark: btw, re. KSP airplanes, you can ask Iskierka or ferram4 about thoughts on airplane design, that's a great way to learn things about aerodynamics

well removing Fashionably hasn't quite solved my problem apparently

please don't do γ-imagery of cats
<whitequark>
and probably don't do X-rays of cats either unless it's like, a licensed CT machine
<whitequark>
I know a guy who got up an X-ray tube and then observed his hand on a scintillator or something until he got a few roentgens into it
<egg|zzz|egg>
whitequark: well, I was thinking imagery in the astronomical (non-arecibo) sense, just staring at photons emitted by the object, or reflected from astronomical sources off the object; which admittedly will yield very dim catpics in those wavelengths
<whitequark>
that fucked it up pretty well
