<SnoopJeDi> bofh, ...I fell down the sonification rabbit hole and ended up at this: https://www.youtube.com/watch?v=vZi-hXWjRWY
<kmath> YouTube - Kronos Quartet w/ Total Solar Eclipse Sonification | Exploratorium
<SnoopJeDi> Live data-driven (think noisebox) composition for 3 hours, joined by a quartet for ~40 min around totality
<bofh> Okay, this seems *fascinating*
<bofh> also rofl a friend of mine gifted me some standard Lindt chocolate and I ate the entire thing in like, a half-hour while talking to them.
<bofh> it's not my fault most chocolate here in the USA is dogshite and so when I get something actually reasonable I'll just eat the whole damn thing,
<SnoopJeDi> I stopped for a bottle of wine on the way home and mosied through the food section of the store as well. Saw a cheddar with (unfortunately artificial) horseradish flavor.

<SnoopJeDi> bofh, have you ever been to an American chocolatier?
<SnoopJeDi> although even if you can source it, it's certainly going to be more expensive because of the milk chocolate obsession with MOAR VOLUME candy manufacturing heh
<bofh> No, and I don't know if I'll have the opportunity to unless there are ones in Chicago.
<bofh> And yeah. Don't forget the butyric acid.
<SnoopJeDi> You'll *definitely* find chocolate in a city that large yea
<SnoopJeDi> We have a nice shop here, even (twin cities, ~150k)
<SnoopJeDi> Two if you're willing to endure a 30 minute drive (which is practically next-door by Texan standards)
<SnoopJeDi> But then, maybe I'm my American tastes aren't up to snuff ;P
<bofh> (it was fun starting an explanation to egg about why US mass-market milk chocolate is so vile with "so, butyric acid is a 4-chain carboxylic acid present in, among other things, rancid butter & vomit; it is the principal odorant of the former. now, what does this have to do with chocolate, you may ask?...")
<bofh> (funnier still was our discussion about US voting machines and the horror that is the paper butterfly ballots)
<SnoopJeDi> bofh, so I'm teaching my girlfriend a few dishes at her request (this week will probably be a mushroom risotto, *maybe* with spinach wilted in to make it green and hearty)
<SnoopJeDi> and being...me...I couldn't help but talk about the chemistry of the sear on the roasted chicken we did for the first dish, and the principles of emulsion for the pan sauce
<bofh> SnoopJeDi: I mean my standards aren't *that* high, like I love actual proper high-class European Space Foods but those are too expensive for me to eat often, and I basically get chocolate cravings daily, so honestly just about anything that doesn't skimp on the cocoa and *doesn't* add butyric acid to it is okay by my standards.
<SnoopJeDi> and also the fineness of a chop/dice/mince determining the character of aromatics (because oxidation)
<bofh> I mean those are fascinating topics, in all honesty.
<SnoopJeDi> we got to the end of it and she thanked me for pointing out how much there is to everything
<SnoopJeDi> yea, they are! I mean, I think so anyway, but I also accept that a lot of people don't seem to care all that much, food is something that goes in your mouth.
<SnoopJeDi> so it was very gratifying that she took to my cooking style of "I'm gonna need to get a picture in my head for what's happening, here"
<bofh> I mean sure, but if you're going to prepare it, might as well learn about what you're doing.
<bofh> And yep, that's wonderful to hear :)
<SnoopJeDi> yea! I really love Kenji's "hacks" that result from his experimentation on those principles
<SnoopJeDi> "Hmm, this could use some umami...Oh! MSG or fish sauce to the rescue!"
<SnoopJeDi> my favorite being the lemon juice garlic trick that I think I've mentioned before (suppressing alliinase with low pH to prevent hot-garlic flavor)
<bofh> Oh that's neat (and explains pretreating onion with lemon juice prior to slicing).
<SnoopJeDi> bofh, I suspect your standard for chocolate is higher than mine, which is mostly "dark, please."
<bofh> I mean dark is the correct kind imho.
<SnoopJeDi> Ooh, I don't know that trick
<bofh> "Butyric acid is a pharmacologically active compound which functions as an agonist of hydroxycarboxylic acid receptor 2 (HCA2) and the free fatty acid receptors FFAR2 and FFAR3.[13][14] It also acts as a histone deacetylase inhibitor which is selective for class I histone deacetylase enzymes (i.e., HDAC1, HDAC2, HDAC3, and HDAC8).[13][14]"
<bofh> what the hell
<bofh> what the actual hell
xShadowx has joined #kspacademia
<bofh> what even is the endogeneous ligand of HCA2
<bofh> WAIT THAT'S GPR109A
<bofh> AKA THE NIACIN RECEPTOR
<SnoopJeDi> translate up a layer of human abstraction for me?
<bofh> I, what the hell.
<bofh> okay, so niacin (Vitamin B3) when taken in high doses improves cholesterol profiles (and also causes facial flushing).
<bofh> it does this by binding to a particular receptor that I always used to know as GPR109A, b/c it hadn't been named for ages, but was a major pharmacological target
<SnoopJeDi> because of the cholesterol, or for more general effects?
<SnoopJeDi> oh nvm, you said the receptor is a target. I'm with you
<bofh> yeah, b/c of the cholesterol (but also b/c they wanted to create something that had the same cholesterol effects but w/o the facial flushing)
<SnoopJeDi> (leaving aside the pharmacological myth of receptors being a "button" in a vacuum heh)
<bofh> anyway I literally just now learned that apparently this receptor's endogeneous ligand is butyrate/β-hydroxybutyrate (which, fwiw, looks nothing like niacin structurally)
<bofh> which, wtf.
<SnoopJeDi> [1950s+50] "WOW YOU GUYS turns out biochemistry is REALLY pretty complicated"
<SnoopJeDi> [narrator voice] ...I mean yea kinda
<SnoopJeDi> ah!
<SnoopJeDi> ...wow.
<bofh> (also my original what the actual hell is that it functioned as an HDAC inhibitor at some high dose, but that's a lot trickier to explain... basically histone deacetylases are these enzymes that affect gene expression by switching certain genes on and off by adding acetyl groups to certain parts of the DNA called histones... and it's kind of weird to see a really common simple small molecule to be an
<bofh> inhibitor).
<bofh> like it's triply weird since before skimming wiki just now the main thing I knew about butyrate is that it smelled like rancid butter.
<SnoopJeDi> oh okay, I see it's produced by fermentation, so that is well within biological "huh okay that's imaginable"
<bofh> (which I know from personal experience from crushing and smelling gingko fruit, which contain it in large quantities).
<SnoopJeDi> Yea histones I can grok at this level of abstraction, that's one of the few things that really stuck well in high school bio (regrettably I never had to take courses in college and didn't think to do so for 'fun')
<SnoopJeDi> Things might've gone very differently if I had, I loved microbio then and figured it was a coinflip between that and physics, heh.
<bofh> I mean most of my bio knowledge started out from reading wikipedia
<bofh> (then pubmed when I wanted more detail)
<SnoopJeDi> bofh, ...the above conversation serves as further reason for loving cooking
<SnoopJeDi> inasmuch as it can kick off that sort of conversation when you mix the right folks (a bit like an emulsion!)
<bofh> I mean exactly!
<SnoopJeDi> ...I should get David Weitz to sign a paper or something if he comes here again next year
<SnoopJeDi> for the physics of cooking stuff
<SnoopJeDi> and the associated mini-lecture about chocolate materials physics :D
<bofh> Oh man that sounds *amazing*.
<SnoopJeDi> they have a chocolatier come and do some live tempering and other confectionary stuff
<bofh> OMG I WOULD *LOVE* TO SEE THAT HOLY CRAP
<SnoopJeDi> and it's improved each year so far, so we're all very excited for it to be a running thing at the Festival
<bofh> Nice :)
<SnoopJeDi> bonus shot of the elasticity-of-steak-as-a-function-of-temp bit
<bofh> ROFL PERFECT
<bofh> (also this reminds me of me getting nerdsniped into answering 'from what height would one need to drop a steak from s.t. when it hits the ground it is cooked medium-rare from the reentry?' :P)

<UmbralRaptop> there's some quasi-standard extension to IRC for transferring files.
<bofh> egg|work|egg: hrm. why is this reading like an application of the implicit function thm. to me?
<egg|work|egg> (also, why the hell is mass flow a function of remaining mass in KSP, stabbity,)
<UmbralRaptop> wat
<egg|work|egg> UmbralRaptop: the thrustCurve is a multiplier for m', and a function of the proportion of fuel mass consumed
* UmbralRaptop is failing to understand how the second part of that sentence can possibly work.
* bofh is as well
<bofh> like wouldn't that, erm, turn it into an ODE?
<egg|work|egg> UmbralRaptop: bofh: actually yeah that's very weird considering you can jettison tanks, does your thrust change if you jettison empty tanks and have a thrust curve!?
<egg|work|egg> in practice I think the thrust curve is only used for SRBs that are no-flow
APlayer has joined #kspacademia
<egg|work|egg> bofh: yes, it does, but that's not a problem for KSP, it just Eulers all the thing anyway
<egg|work|egg> at every time step of the game, subtract the right amount of fuel, compute the mass ratio, etc.
<UmbralRaptop> Is this thrust curve as in atmospheric pressure, velocity, or something else?
<egg|work|egg> there are three thrust curves
<UmbralRaptop> aaaaaaa
<egg|work|egg> well, no, there are many curves,
<egg|work|egg> there's atmCurve, atmCurveIsp, atmosphereCurve, throttleIspCurve, throttleIspCurveAtmStrength, thrustCurve, velCurve, velCurveIsp,
<UmbralRaptop> I thought SRBs when 0 <--> max in 1 frame >_>;;
<egg|work|egg> by default, yes, but if you have a thrustCurve (documentation: "The curve to use") this can vary
<egg|work|egg> RO uses that to model actual SRBs
<UmbralRaptop> Is this the documentation that @rygorous was calling homeopathic?
<egg|work|egg> aaaaaah but RO uses another module that has its own thrust curve?!!
<egg|work|egg> wtf
<bofh> LOL
<UmbralRaptop> Does RO just avoid the stock curves?
<egg|work|egg> I don't know
<egg|work|egg> and I don't know if anyone does
<egg|work|egg> aaaah it inherits from ModuleEngines ultimately, so *now* they use the KSP one https://github.com/KSP-RO/SolverEngines/blob/master/SolverEngines/EngineModule.cs#L13
<egg|work|egg> bofh, UmbralRaptop: okay so thrustCurve "the curve to use" is something by NK et al. that got shoved into KSP when they were there
* UmbralRaptop 📄 NK
<egg|work|egg> and somehow NK et al. decided that m'(m_fuel_remaining / m_fuel_initial) was a good idea,
<egg|work|egg> !u 📄
<Qboid> U+1F4C4 PAGE FACING UP (📄)
<UmbralRaptop> stabbing with a sheet of paper
<UmbralRaptop> I can see why thrust would want fuel remaining, but why initial fuel?
<egg|work|egg> UmbralRaptop: because NK probably wanted some normalized support so it's a function on [0, 1]
<UmbralRaptop> oh
<egg|work|egg> bofh: tbh it might be better to just solve the ODE, since I'll need to do that if I want to simulate the fuel flow logic anyway
<egg|work|egg> (yes I'm going to have to simulate KSP except I'll be integrating it properly, stabbity,)
<UmbralRaptop> KSP, but each physics step uses leapfrog instead of normal Euler?
<egg|work|egg> nah, a high-order method
<egg|work|egg> and probably variable steps for things like fuel flow, there's no symplecticity anyway
<egg|work|egg> bofh: I wonder whether I should pre-integrate the fuel flow ODE, interpolate F(t) and m(t) and use that in the equation of motion, or whether I should integrate it all at the same time
<bofh> egg|work|egg: the former sounds marginally trickier but also a lot saner.
<awang> egg|work|egg: What is mass flow supposed to be a function of? Time?
<awang> thrustCurve being a function of the proportion of fuel mass consumed makes me want to see those SRB thrust-over-time curves compared against thrust-to-mass-consumed
<awang> Like what is that supposed to look like
<awang> "homeopathic documentation"
<awang> I need to remember that
<Sarbian> You only have to trust that it works
<egg|work|egg> !wpn Sarbian
* Qboid gives Sarbian a gravitomagnetic meson
<egg|work|egg> awang: well, a function of time would be way more convenient
<egg|work|egg> also a function of fuel remaining / initial fuel is really weird when initial fuel can change if tanks are jettisoned :-p
<egg|work|egg> drop empty tank -> change thrust

<Sarbian> (but I did get a new keyboard)
<awang> egg|work|egg: Oh jeez that's a good point
<awang> I'm curious I haven't heard of thrust changing with dropping tanks before
<awang> Does KSP compensate for it or something?
<awang> Er, thrustCurve changing
<Sarbian> hum, mass changes ?
<awang> UmbralRaptop: I didn't know "potemkin" was a word
* UmbralRaptop blinks
<awang> Also, that guy's recent tweets on autovectorizing COBOL compilers makes me really want to hear those compiler war stories
<awang> Sarbian: True
<egg|work|egg> awang: Sarbian: it's not so much that mass changes (fuel mass doesn't change), but "total fuel mass" as computed by KSP changes
<egg|work|egg> which means the thrust changes when using a thrustCurve
<egg|work|egg> (which it shouldn't; the mass change obviously causes a change in acceleration, but that's different)
<kmath> <uenoune> 香港お土産にもらった可愛いクリップ。「小心同事」は社内で何があったんだ…。 https://t.co/ofxlfU1yvT
<Sarbian> hum. I do not remind anything using the total fuel mass
<egg|work|egg> Sarbian: thrustCurve does
<awang> egg|work|egg: Right, I just don't remember seeing anything thrust-related when dropping tanks in right-click menus or MJ/KER
<egg|work|egg> Sarbian: it's only documented as "The curve to use", but it's upstreamed from https://github.com/NathanKell/ModularFuelSystem/blob/21b0bad4170ba496657cfd25901ddf60473c8bd4/RealFuels/Readme_RF.txt#L479
<Sarbian> oh yeah. I see it now
<egg|work|egg> Sarbian: maybe your fuel simulator doesn't take thrustCurve into account? in practice it's only used by RO SRBs
<Sarbian> I ll check
<egg|work|egg> Sarbian: also I feel like I'm going to write my own fuel simulator eventually :-p
<egg|work|egg> MOAR FUEL FLOW SIMULATORS
<Sarbian> Well SRB drop tank are not a thing I guess :D
<egg|work|egg> yeah
<egg|work|egg> it's more that if you used thrustCurve on liquid engines you would get *really weird* behaviour
<Sarbian> MJ ignores it.

<UnqualifiedRaptor> egg: oh, good. I'm north of the cone. (Is it a 1 σ cone?)
<egg> ask bofh
<egg> bofh knows about things
<UnqualifiedRaptor> I *think* this means that it'll just be a bad t-storm.
<egg> I know that the ANBO barometer says "variable"
<egg> the ANBO barometer is a bit odd
<egg> it has 76 cm Hg at the top, goes down to Nice and up to 80
<SnoopJeDi> UnqualifiedRaptor, "The cone represents the probable track of the center of a tropical cyclone, and is formed by enclosing the area swept out by a set of circles (not shown) along the forecast track (at 12, 24, 36 hours, etc). The size of each circle is set so that two-thirds of historical official forecast errors over a 5-year sample fall within the circle."
* UnqualifiedRaptor was eggstremely confused as to why Nice would see lower pressures than ANBO.
<egg> no, not the city,
<UnqualifiedRaptor> SnoopJeDi: uh, fake 1 σ, I guess?
<SnoopJeDi> I've seen someone refer to such cones as marking areas of equal probability
<UnqualifiedRaptor> gaj
<UnqualifiedRaptor> *gah
<SnoopJeDi> guess it depends on how you think errors are distributed. uniform doesn't seem implausible
<SnoopJeDi> Meteorology really needs to step it up in terms of communicating probabilities :|
<egg> UnqualifiedRaptor: roughly these markings, though the ANBO one looks fairly different https://le-pere-yves.fr/wp-content/uploads/347626-474x500.jpg
<SnoopJeDi> UnqualifiedRaptor, it's worth making preparations if you had to leave the area. Just having a bag packed is a HUGE difference </emergency_preparedness_meritbadge>
<SnoopJeDi> egg, why is that odd?
<egg> well, the discontinuity being off to the side is a bit funny
<egg> also the words have limited usefulness, at ANBO it's always "variable" (and often rainy)

<SnoopJeDi> oh between the high/low values? I would assume it'd be more legible if it were a segment on an arc, yea
<UnqualifiedRaptor> egg: the rain is a uniform random variable?
<egg> um
<bofh> egg: I still can't get over the ANBO barometer using cmHg as a unit.
<egg> what's wrong with cm Hg, :-p
<SnoopJeDi> that's water from rainfall, too
<bofh> !acr -add:MEOW Maximum Envelope Of Water

<bofh> MEOW?
<Qboid> bofh: [MEOW] => Maximum Envelope Of Water
<bofh> oh cool.
<SnoopJeDi> not sure if they do comparable gfx for storm surge though

<Qboid> egg: I added the explanation for this acronym.
<APlayer> What about solid rocket fuel?
<SnoopJeDi> Isabel knocked the cooling offline and all the Qs for the cavities changed
<bofh> Oh yuck.
<bofh> When was Isabel again btw?
<SnoopJeDi> 2003
<bofh> oh, so awhile ao.
<bofh> ago*
<egg> meow
<SnoopJeDi> Florence is getting more comparisons to Andrew, though, which was *bad*
<SnoopJeDi> bofh, yea, it screwed with heat load management for a while. I'm aware of it because of this neat paper: https://journals.aps.org/prab/abstract/10.1103/PhysRevSTAB.17.101003
<SnoopJeDi> Balša's a really nice guy
<bofh> SnoopJeDi: like, I'm afraid it'll turn into the Carolinas' Harvey
<SnoopJeDi> And knows optimization inside and out
<SnoopJeDi> bofh, yea. I'm hoping it doesn't stall.
<UnqualifiedRaptor> bofh: Hugo 2.0?
<SnoopJeDi> But AFAICT the odds of a stall are pretty good
<bofh> the models have it stalling inland for 12h-48h atm, but that bit's somewhat finicky compared to our over-water models, so I'm hoping that doesn't happen.
<SnoopJeDi> and the East just isn't used to dealing with flooding
<bofh> like the fact that it's going to run aground as a cat4 or cat5 is already horrifying.
<SnoopJeDi> yep
<bofh> esp. in a place that just isn't used to hurricanes.
<bofh> at least of that magnitude

<UnqualifiedRaptor> … you're making it sound like I should drive out to Dayton and crash at B787_300's or Rokker's
<SnoopJeDi> UnqualifiedRaptor, see above re: at least have a bag
<bofh> ^
<SnoopJeDi> I'm a little touchy on hurricanes considering last year, though
<SnoopJeDi> Gave my dad the same lecture over the weekend because they live on the water in MD (so, probably fine)
<bofh> Same, and I wasn't even in an affected area. (Hoping that Hurricane-where-is-IL doesn't ever happen).
<SnoopJeDi> I've been thinking a lot about where in the US I'd like to move
<bofh> *checks NHC site* oh come ON, possible two NEW hurricanes within 48h?!?
<bofh> on top of the three that already exist.
<bofh> (well, tropical storms at least)

<SnoopJeDi> Helene is at least just gonna blow itself out
<bofh> I recall commenting to someone in Paris back in August that this year was so far unusually quiet re: hurricanes.
<bofh> Turns out they just ambushed in packs this year.
<SnoopJeDi> I don't usually pay much attention, but it seems hard to say from where we stand
<bofh> Like, so far this is mirroring a slightly delayed last year :/
<SnoopJeDi> A lot easier to point to the differences in warm-water energy, ground soak, etc.
<SnoopJeDi> and uh
<SnoopJeDi> the atlantic current slowing down
<SnoopJeDi> but global conspiracy or whatever
<bofh> I mean there's about as much warm water energy off the East coast.
<bofh> +as last year*
<SnoopJeDi> right
<bofh> that's how Florence went from a tropical depression to a cat4 in like, 48hrs.
<SnoopJeDi> and we can say for sure that *that* is anomalous
<SnoopJeDi> and two seasons in a row wow lookie that
<bofh> just needed the wind shear to go away and then burst of deep convection and there you go, swirling ocean death.
<bofh> YEP.
<SnoopJeDi> I'm quite bitter about it
<bofh> SAME.
<SnoopJeDi> and also everything
<bofh> I mean EU got hit pretty badly by ~*~ le canicule ~*~ this year too.
<SnoopJeDi> huh, I didn't realize "dog days" was related to Sirius

<egg> bofh: there are *a lot* of them https://fr.wikipedia.org/wiki/Les_Deux_Amies
<bofh> egg: there's a part of me that *almost* wants to go to the Grande Galerie this time around but OTOH, no thanks, too many crowds.
<egg> bofh: wtf, don't dismiss the paintings entirely, the grande galerie in nocturne in autumn should be fine
<bofh> egg: so I'm waiting until the crowds become acceptable.
<egg|zz|egg> anyway, there are other museums too
<egg|zz|egg> some of those on that page are in the petit palais
<bofh> like I don't really have social anxiety at all but the crowds I saw in August even out by Νίκη της Σαμοθράκης still made me go "hm... nah". :/
<bofh> Petit Palais is def. on my "to attend" list.
<bofh> (granted, August in .fr is I think a particularly bad time for crowds)
<egg|zz|egg> bofh: uh, so, Νίκη is kind of a popular piece, and you were there *in summer*, also iirc during daytime
<bofh> Yeah, daytime around 16:30 iirc.
<egg|zz|egg> lol
<bofh> I mean I know Nocturne is the correct time to attend, and I'll hit up the paintings eventually during a Nocturne, it just may take a bit just given the scope of the Louvre.
<egg|zz|egg> bofh: obviously avoid the joconde (though you might be able to look the other way at the Noces de Cana), but even during daytime it's not catastrophic usually
<bofh> like again, I spent 2x evenings and an entire day there and I think I can confidently say I covered maybe 10% of 2 wings.
<bofh> :p
<bofh> And I didn't eggsactly stay in one place or loiter either.
<egg|zz|egg> that's a lot actually :-p
<egg|zz|egg> yeah, you should spend more time loitering :-p
<bofh> I mean yeah, that is the plan,
<egg|zz|egg> (Joconde is left of frame)
<egg|zz|egg> well, behind really
<egg|zz|egg> opposite the Noces
<bofh> I mean when I went with my parents in 2006 they went to see the Joconde and I took a look at the Noces, walked around a good few halls and still had enough time to sit and daydream out a window and come back before they got to see the Joconde, lol.
<bofh> but we went also during August then
<bofh> that crowd in the image you linked is actually reasonable
<egg|zz|egg> bofh: no, the crowd is left of frame and behind
<egg|zz|egg> the crowd is likely never reasonable there
<egg|zz|egg> esp. for a painting this size
<bofh> I mean I'm referring to the crowd *outside* the Joconde line.
<egg|zz|egg> maybe late in nocturne on a shitty winter day
