<Thomas> :D
<egg|unit_tests|egg> whitequark: the Qboid weapon combinatorics occur here https://github.com/StollD/QIRC.Kerbal/blob/master/Source/QIRC.Weapons/Weapon.cs#L157
<egg|unit_tests|egg> Qboid used to put that in a signed 32-bit integer, which we promptly overflowed
<Thomas> *whistle*
<whitequark> reminds me that rust has a library for dealing with overflows in a structured way
<whitequark> it's called "overflower"
<egg|unit_tests|egg> cute :D
<egg|unit_tests|egg> whitequark: so I figured out that the bug that for which we had done (and are still doing) a big refactor of half the ksp_plugin was actually something I had misdiagnosed, and was fixed with a dozen lines in the C# layer. Sooo, I guess that had I been less stupid you could be playing principia with 1.2 now :-p
<egg|unit_tests|egg> but then this refactor will give us conservation of momentum when engines are not firing, which is nice
<Thomas> haha
<egg|unit_tests|egg> the KSP APIs are so fun to work with
<egg|unit_tests|egg> and by that I mean "at least they don't try obfuscating the code anymore"
<whitequark> ha, I wondered how you deal with that
<egg|unit_tests|egg> and by that I mean "but then given how it's written that's not much of an improvement"
<whitequark> lol
<egg|unit_tests|egg> they used to obfuscate, but that was fairly trivial to read
<egg|unit_tests|egg> because their shitty obfuscator added empty loops with a goto or a case
<egg|unit_tests|egg> and that looked nothing like the real code, so you just skipped that
<whitequark> so I wrote a deobfuscator/decompiler for flash once
<whitequark> if they ever start it again...
<egg|unit_tests|egg> some people used a deobfuscator too, I just used a decompiler
<egg|unit_tests|egg> I think someone tried deobfuscating the assembly and noticed that the performance increased measurably?
<egg|unit_tests|egg> Stratege_: it was you, right?
<egg|unit_tests|egg> !seen Stratege
<Stratege_> hm
<Qboid> egg|unit_tests|egg: I haven't seen the user Stratege yet.
<Stratege_> I don't think I ever got a deobfuscated version to run. But I did notice that there are some horrible issues in the original code.
Stratege_ is now known as Stratege
<Stratege> actually, I might have once.
<Stratege> But tbh, most of what I recall from diving way way too deep into the source was one function that was in O(n^5) or something where n is the part count of a rocket.
<Stratege> And which probably was a big part of why large rockets killed perf
<egg|unit_tests|egg> that's... impressive? :D
<Stratege> yeah...
<Stratege> loops within loops within recursion.
<Stratege> I never got that fixed version done and patched in for testing perf differences though, sadly :/
<Thomas> egg|unit_tests|egg: I think 32-bit is still obfuscated, 64-bit isnt
<Thomas> because jenkins incompetence or something like that xD
<egg|unit_tests|egg> The APIs are something though: to get the velocity of an Orbit, you have GetVel(), GetWorldSpaceVel(), getOrbitalVelocityAtObT(double, double, out Vector3d), getOrbitalVelocityAtTrueAnomaly(double), getOrbitalVelocityAtUT(double), GetRelativeVel(), GetFrameVel(), GetFrameVelAtUT(double), and vel. They're all in m/s, but I have no bloody idea which frame they're in (in particular, "World" is misleading,
<egg|unit_tests|egg> because it may or may not include the Krakensbane velocity offset)
<whitequark> krakensbane??
<whitequark> getOrbitalVelocityAtTrueAnomaly???
<egg|unit_tests|egg> that identifier makes sense
<egg|unit_tests|egg> krakensbane... less so
<Thomas> krakensbane is a hack for allowing large speeds of an object in unity
<whitequark> whats true anomaly
<egg|unit_tests|egg> a parameterization of an orbit
<Stratege> I mean krakensbane is just the attempt to move things around so you don't lose precision with floats in the realm where you care about it.
<egg|unit_tests|egg> otoh, what's ObT? No fucking clue
<Thomas> orbital time?
<Thomas> (I have no idea)
<Stratege> wasn't there a documentation project at some point? To get some somewhat okay-ish docs for the API nightmare?
<Thomas> There are docs from squad now
<egg|unit_tests|egg> whitequark: true anomaly is an astronomer thing, it's the time since periapsis, rescaled from 0 to 2π.
<Thomas> Well "docs"
<whitequark> oh
<Stratege> I'd trust squad docs about as much as I'd trust their code to be sane.
<egg|unit_tests|egg> whitequark: so Unity does its crap in binary32, so you want to use high bits in double + low bits in a float or somesuch; so first they did that for positions, with FloatingOrigin, a sane name. but their velocities were smallish (that was when there was one celestial body, Kerbin, the sun was but a lens flare)
<Thomas> It got a lot saner in 1.2
<Thomas> partly because NK stopped sleeping
<Thomas> :P
<whitequark> NK?
<whitequark> egg|unit_tests|egg: wait ksp used to have only one celestial body?
<Thomas> NathanKell
<Thomas> A former developer
<Thomas> whitequark: Yup
<egg|unit_tests|egg> whitequark: and then they added celestials, and people went to solar orbit, and velocities were large, and their vessel was destroyed in strange ways. And they did complain about it on the fora, and they did call it the kraken. And in that time squad wrote a floating origin but for velocities, differently, and independently, and they did call it Krakensbane. And the people did feast upon the lambs, and
<egg|unit_tests|egg> sloths, and carp, and anchovies, and orangutans, and breakfast cereals, and fruit bats, and---
<whitequark> damn I want food now
<Stratege> and the literary style of the bible is not recommended.
<egg|unit_tests|egg> :D
<egg|unit_tests|egg> Stratege: it's appropriate to recount the nonsensical tales of squad development
<Stratege> fair enough xD
<egg|unit_tests|egg> whitequark: and in those strange eons of early KSP, in a time before timewarp, the Sun was but a flare fixed in the skybox, and Kerbin did not rotate, and the dark side of Kerbin exploded all who landed there. And it was in that time that the first modders appeared, making part mods because there were no plugins.
<Thomas> and then there was the modder that made the plugin loader
<egg|unit_tests|egg> [who was that actually? I don't remember that time quite well, because I dropped KSP for a while when I started studying at ETH]
<Thomas> N3X15
<egg|unit_tests|egg> oooh
<ferram4> Yes, who got hired on very early.
<egg|unit_tests|egg> Nova was one of the two earliest part modders that I remember
<egg|unit_tests|egg> there was SundayPunch whose work was quite popular early on
<ferram4> But he was never hired.
<egg|unit_tests|egg> SundayPunch disappeared afaict, Nova got hired
<egg|unit_tests|egg> also, fuck, that was in *2011* ?! blarg
<whitequark> you're old. also, I'm old
<egg|unit_tests|egg> well if you are to be believed we're about equally old :-p
<egg|unit_tests|egg> (assuming that you didn't follow some weird geodesics)
<whitequark> hahaha
<egg|unit_tests|egg> also principia was started in 2014
<egg|unit_tests|egg> well maybe some code was written in late 2013 before I gitted it
<egg|unit_tests|egg> gitted? that sounds like it should be an irregular verb
<egg|unit_tests|egg> so while I'm recounting ancient history, Nova is a central character to the creation of Principia
<egg|unit_tests|egg> in late 2013 he made a custom solar system, Alternis Kerbol http://forum.kerbalspaceprogram.com/index.php?/topic/57742-023-alternis-kerbol-release-thread-v01-jan-3-development-halted/&page=1
<egg|unit_tests|egg> and he was interested in the stability thereof (with some alternatives, there was the possibility of a tiny bop as a moon-of-a-moon, which I dubbed Boepli in swiss fashion)
<egg|unit_tests|egg> I knew about symplectic integrators from my numerics course, so I tried running things in Mathematica to simulate it, with the options chosen to use symplectic integrators. That was a bit slow since I was always poking a new modified system, so I wrote the integrator in C# (and then I emitted text to plot with Mathematica, it's nice for data visualization)
<egg|unit_tests|egg> it wasn't very stable btw http://imgur.com/a/VO1h6
<egg|unit_tests|egg> another simulation run: http://imgur.com/a/l2nW1
<egg|unit_tests|egg> at which point Nova poked me into putting that integrator into KSP to see how much it would slow things down (not at all, at the time it was just celestials), and after some confusion with KSP's API yielding http://i.imgur.com/0ugq0e5.png I got some prototype plotting http://imgur.com/a/FSZ4h
<egg|unit_tests|egg> and that was the start of principia, except when I started writing it I got tired of always confusing reference frames and units, so I tried using strongly-typed quantities, which C#'s type system can't really do, and we switched to C++ (around that time phl joined)

<egg|unit_tests|egg> bofh: I was using my father old's refractor in normandy, and during the day there's not much to look at except the cows across the Seine; so I took those photos; then Iskierka looked at some cows (possibly other animals) in her telescope in England
<bofh> LOL
<bofh> so what's the magnification on that?
<egg|unit_tests|egg> hmm, I don't recall, but I think the most magnified are with barlow... lemme check, I have my scope config saved in stellarium
<egg|unit_tests|egg> so, the refractor is 800 mm focal length, the eyepiece is probably either the 4 mm ortho or the 6 mm HM

<whitequark> hi regex
<SnoopJeDi> bofh, you're a superconductivity whatsit?
<bofh> I'd say theorist but that's not quite true at this point.
<SnoopJeDi> My labmate's thesis topic is Bi-2212 wire fabrication!
<egg|nomz|egg> this feels like a differential geometry problem, fundamentally https://twitter.com/sigfig/status/840294191892590592
<kmath_> <sigfig> the basic mechanic the algorithm for this includes distorting distances to synchronize with walls and tables https://t.co/pLBYrsQWrw
egg|nomz|egg is now known as egg
<egg> whitequark: further on the "french people give silly names to things" point, I named something "conifer" in my MSc. thesis
<egg> it's something that feels a bit like a tree (it's counted by Catalan numbers at least), and it is made of cones :-p
* whitequark stares at egg
<Thomas> That repository name deserves an award
<egg> well that's just the title of my thesis
<Thomas> Still, thats the longest repo name I've ever seen
pizzaoverhead has joined #kspacademia
<egg> yeah typically repo names don't look like paper titles for some reason
<egg> o/ pizzaoverhead, meet whitequark and bofh
<pizzaoverhead> egg! \o
<pizzaoverhead> 'Sup whitequark and bofh
<pizzaoverhead> :D
<egg> inf whitequark and bofh >_>
<whitequark> hi pizzaoverhead
<whitequark> ... food again!
<pizzaoverhead> Hey whitequark!
<whitequark> also egg is food
<whitequark> i am in hell!
<egg> D:
<egg> ... I may have made this joke to whitequark a page above :D
<pizzaoverhead> ...joke? :D
<whitequark> lol
<pizzaoverhead> I must revive the pizza pod mod.
<egg> pizzaoverhead: <whitequark> maybe I should just go buy some<egg|unit_tests|egg> that sounds like a solution to that problem<egg|unit_tests|egg> whitequark: I mean, I'd gladly offer some, but I don't have an ICBM at hand to lob food at you
<whitequark> in hk there's a brand of fruit juice called "minutemaid"
<bofh> > My labmate's thesis topic is Bi-2212 wire fabrication!
<whitequark> and all i can think of is the ICBM
<bofh> oh COOL!
* UmbralRaptor is fairly certain that minutemaid is also a thing in the US.
<whitequark> oh it's just whitewashed cocacola
<egg> whitequark: speaking of food, drinks, and missiles, I launched a bottle of wine into orbit with KSP (RO) a while ago http://imgur.com/a/gLG9j
<whitequark> why is it angled? O_o
<whitequark> I've never seen anyone build craft like that
<egg> whitequark: no guidance except on the last stage, japanese style
<egg> well there is no wine in RealFuels so it was probably hydrazine or somesuch to get a close enough density
<whitequark> oh
<whitequark> huh
<egg> I like the MJ graphs btw
<pizzaoverhead> egg: Reminds me of something: http://postwarv2.com/littleJoeII/js640_andrey_little_joe_II_01.jpg
<pizzaoverhead> Also RO is looking stunning these days.
<bofh> SnoopJeDi: currently feeding ~60T across some La(1.8-x)Eu0.2SrxCuO4 and watching AC susceptibility data
<egg> whitequark: the first stage of that is the first stage of a Minuteman I (M55) I think?
<SnoopJeDi> neato
<pizzaoverhead> egg: Entirely unrealistic though. No cloud cover over the British Isles.
<egg> I hadn't installed the clouds mods
<SnoopJeDi> bofh, I don't do any of the SC stuff, I mostly spend my time thinking about accelerator dynamics and making bad simulations thereof
<egg> just blackrack's shaders mods probably
<egg> pizzaoverhead: also taht was 1.0.5
<pizzaoverhead> :D
<SnoopJeDi> but since we're a magnet lab it's a subject of some concern to us
<pizzaoverhead> No Planetshine?
<bofh> which one?
<bofh> ^SnoopJeDi
<SnoopJeDi> bofh, TAMU
<SnoopJeDi> I mean, I say "magnet lab" but there hasn't really been much rubber meeting the road since 2013 on hardware, DOE yanked the carpet out from under us
<bofh> ahh, ouch.
<SnoopJeDi> Seems like the official US policy on magnets is to close up shop
<bofh> I'm at LANL Pulsed-Field for another uh 6 hours
<pizzaoverhead> That sucks :/ Seems to be the policy on lots of research these days.
<SnoopJeDi> oh neat
<SnoopJeDi> ever met a Dr. Wood? (or maybe she goes by Dr. Sooby out there)
<bofh> also starting to suspect the US policy on * is to close up shop
<SnoopJeDi> bofh, the fact that a DOE proposal I was supposed to hear about 2 weeks ago is still outstanding seems to agree
<bofh> so like the entire US govt is currently, uh
<pizzaoverhead> The UK decided to leave Euratom earlier this year, cutting the funding for the JET tokamak.
<bofh> somewhere between nonfunctional and negative expected utility?
<pizzaoverhead> It ain't just the US
<SnoopJeDi> Certainly not in accelerators
<bofh> oh man I forgot about Brexit almost. yaey.
<SnoopJeDi> CERN's official policy re: FCC is "16 T IS VERY FEASIBLE LA LA LA WE CAN'T HEAR YOU"
<pizzaoverhead> breuratomexit is the worst part
<bofh> FCC?
<SnoopJeDi> "future circular collider"
<SnoopJeDi> 100 km, 100 TeV mega-LHC basically
<SnoopJeDi> 100 km circumference, that is
<egg> !acr -add:FCC Future Circular Collider
<Qboid> egg: I added the explanation for this acronym.
<egg> (to test the latest and greatest from what's featured in the Not Even Wrong blog, I gather? :-p)
<pizzaoverhead> !acr FCC
<Qboid> pizzaoverhead: [FCC] => Future Circular Collider
<pizzaoverhead> :D
<SnoopJeDi> egg, you think they have a purpose?
<egg> SnoopJeDi: well, yes, also they're good toys :-p
<SnoopJeDi> the state of high-energy hadron is "lol it'd be cool though," there's no reason to expect 100 TeV to be a particularly important energy
<egg> (had a TA who worked on CMS in physics I)
<SnoopJeDi> and FCC certainly didn't pick their numbers for physics reasons
<SnoopJeDi> egg, the detector people have it even worse!
<egg> s/physics/Physik
<SnoopJeDi> Supposing you could build such a monster machine, the pile-up would make LHC look like a cakewalk
<Qboid> egg meant to say: (had a TA who worked on CMS in Physik I)
<bofh> SnoopJeDi: so they claim 16T ring magnet fields or what?
<bofh> also rofl I agree 16T is feasible but that depends on the timescale involved)
<SnoopJeDi> 16 T is their absolute minimum
<SnoopJeDi> and that's bending field
<SnoopJeDi> not "this is how we're deciding on J_e" field
<SnoopJeDi> so in reality, they probably *actually* need an 18 T bending field and a magnet with a short-sample limit of ~ 20 T
<SnoopJeDi> but even taking them at face value, 16 T is pants-on-head insanity
<SnoopJeDi> FNAL has some notion of like a 6-shell cos(θ), there's talk of a so-called "canted" cos(θ) floating around...
<bofh> LOL
<bofh> Yeah I assumed when you said that you meant bending field, which, uh, I wish them luck.
<SnoopJeDi> yyyyyep
<egg> FNAL?
* egg pokes Qboid
<bofh> I assume Fermilab Accelerator?
<SnoopJeDi> !acr -add:FNAL Fermilab National Accelerator Laboratory
<Qboid> SnoopJeDi: I added the explanation for this acronym.
<egg> the site says Fermi National Accelerator Laboratory
<SnoopJeDi> err, yea
<egg> otherwise there are too many labs
<SnoopJeDi> (nobody calls it that, it's Fermilab)
<egg> !acr -update:FNAL Fermi National Accelerator Laboratory
<Qboid> egg: I updated the explanation for FNAL
<SnoopJeDi> Just like nobody calls Jefferson Lab "Thomas Jefferson National Accelerator Facility"
<bofh> rofl yep
<egg> !ACR -ADD:TJNAF Thomas Jefferson National Accelerator Facility
<Qboid> egg: I added the explanation for this acronym.
<egg> Thomas: sorry about all the pinging :D
<Thomas> pong
<SnoopJeDi> it'll be neat if the US builds an electron-ion collider, though
<UmbralRaptor> !acr -add:LANL Los Alamos National Laboratory
<Qboid> UmbralRaptor: I added the explanation for this acronym.
<SnoopJeDi> probably our last best shot at dominance in a "traditional" accelerator sense
<UmbralRaptor> Is RHIC still doing anything?
<SnoopJeDi> yep!
<SnoopJeDi> there's an eRHIC conceptual design for an EIC that competes pretty directly with JLab's concept
<Iskierka> surely the US has enough empty land to just build something LHC-sized above ground for easier maintenance
<SnoopJeDi> eRHIC would add an electron ring to a proton (and kinda ion) machine, JLEIC would add a proton complex to CEBAF
<UmbralRaptor> Isli
<UmbralRaptor> er
<UmbralRaptor> Iskierka: like SCC?
<SnoopJeDi> Iskierka, it'd be way worse
<SnoopJeDi> to build it above-ground, I mean
<SnoopJeDi> for pretty much every reason you can think of
<UmbralRaptor> SnoopJeDi: rogue cows?
<SnoopJeDi> except $$$ I guess
<egg> SCC?
<Iskierka> isn't that america's only care?

<SnoopJeDi> (might as well)
<bofh> Heh. This is actually a fairly useful bot.
<egg> well
<egg> !wpn bofh
* Qboid gives bofh an indium goose
<whitequark> nice
<bofh> hey like that would be very useful for that vacuum chamber
<egg> bofh: goose-shaped seals?
<bofh> why not? possibly might need to deform it a little though
<egg> whitequark: (also apologies, geese are food too)
<bofh> so I did undergrad in a location which had basically a goose sanctuary
<bofh> so many canada geese. way more than necessary.
<SnoopJeDi> Any number of canada geese is more than necessary
<SnoopJeDi> Vicious little jerks
<bofh> They're as vicious as they are stupid :P
<bofh> Had one that spent most of his day attacking his reflection in a building
<whitequark> egg: i don't think geese are food
<whitequark> also chickens aren't food
<whitequark> chicken *meat* is food though
* egg finds geese tasty than ducks tbh
<whitequark> ... now i did it to myself
<egg> uh the preceding message lacks a comparator
<egg> s/tasty/less tasty/
* Qboid finds geese less tasty than ducks tbh
<pizzaoverhead> whitequark: You can eat every part of a chicken :D
<pizzaoverhead> It might not be a good idea, but you can :D
<egg> pizzaoverhead: pigs too
<whitequark> pizzaoverhead: no, *I* can't
<bofh> mm... vCJD

<UmbralRaptor> (also, is whitequark fasting, or something?)
<whitequark> UmbralRaptor: nope
<whitequark> just can't be arsed to go get food
<egg> :D
<whitequark> I haven't eaten for like 30 hours at this point
<whitequark> it's mildly annoying
<egg> oh fuck O_o
<egg> ok, we must jointly fund an ICBM to send a pizza to whitequark
<whitequark> ... a few weeks ago I rediscovered KSP and just played it for four days straight
<pizzaoverhead> !acr ICBM
<Qboid> pizzaoverhead: This key is not registered!
<whitequark> I slept
<whitequark> but that was it
<egg> (or duck confit or whatever)
<whitequark> sleep and KSP
<egg> whitequark: ... drink at least?
<whitequark> yeah
<whitequark> water
<bofh> whitequark: so like your food schedule is like my sleep schedule
<pizzaoverhead> !acr -add:ICBM Intercontinental Ballistic Missile
<Qboid> pizzaoverhead: I added the explanation for this acronym.
<whitequark> actually you stop feeling hunger after about two days
<whitequark> but it became somewhat hard to walk
<egg> O_o
<whitequark> bofh: I *used* to have sleep schedule like that (well it was never quite as bad)
<whitequark> I think at some point I watched the entire Battlestar Galactica in one go
<pizzaoverhead> google ICBM: Top stories: "Revealed: This is when Kim Jong-un's ICBM nuke will hit the US"
<pizzaoverhead> No. Bad google.
<bofh> no. that is not a thin.
<bofh> thing*
<whitequark> what isn't
<bofh> NK having ICBMs with that range.
<whitequark> ah yeah.
<egg> bofh: or at least that range *and that precision*
<egg> they have orbital launchers
<bofh> when did google get into the business of shoddily scraping their search results for keywords and then reporting that as "news"?
<whitequark> bofh: about a year ago I think
<egg> the machine learning people are nuts I believe
<bofh> I refuse to believe it's even ML since how do you fuck up ML that badly
<pizzaoverhead> bofh: Hawaii and Alaska perhaps.
<egg> the problem is googlers are sort of the last to learn about google things, so this has started making waves internally
<egg> (i.e. memegen is full of it)
<pizzaoverhead> bofh: ML relies on a sensible training set
<whitequark> bofh: I think by living in San Francisco
<pizzaoverhead> !acr ML
<Qboid> pizzaoverhead: This key is not registered!
<bofh> so have we finally come to the consensus that the NK seismic signatures are that of nukes and not, like, someone tossing a bunch of ANFO down a mineshaft and lighting it?
<whitequark> it's like -10 to wisdom
<pizzaoverhead> !acr -add:ML Machine learning

<whitequark> !acr -add:SF San Francisco
<Qboid> whitequark: I added the explanation for this acronym.

<whitequark> egg: 21:36 <@bofh> NK having ICBMs with that range.
<pizzaoverhead> !acr -add:EGG Evaporating Gaseous Globule
<Qboid> pizzaoverhead: I already know an explanation for EGG! (Update it with !acr -update:EGG Evaporating Gaseous Globule)
<whitequark> oh
<pizzaoverhead> EGG?
<Qboid> pizzaoverhead: [EGG] => Educated Gravity Geek
<whitequark> lol
<egg> that's gregox
<pizzaoverhead> !acr -update:EGG Evaporating Gaseous Globule
<Qboid> pizzaoverhead: I updated the explanation for EGG
<whitequark> I *wish* HK had dominos
<whitequark> since that's the only sort of pizza I consider edible
<whitequark> but no
* egg considers shipping whitequark some homemade duck confit
<whitequark> what's confit
<egg> (but then maybe they wouldn't consider that edible)
<egg> whitequark: salted duck cooked in fat with spices
<pizzaoverhead> whitequark: confit is definitely short for confetti.
<egg> (in duck fat that is)
<whitequark> fat ._.
* whitequark doesn't like fat
<pizzaoverhead> whitequark: What about oil?
<whitequark> i never use fat when cooking (which is why i only cook on teflon)
<whitequark> yeah, same with oil
<whitequark> and butter
<whitequark> and... etc
<egg> D:
<egg> no butter? D: D: D:
<whitequark> no butter.
<pizzaoverhead> Triglycerides?
* egg french, so sauces are 50 % butter by mass
<whitequark> i guess *very small* amounts of butter are fine
<egg> puree too :-p
<pizzaoverhead> Ooh, dominos has arrived
<whitequark> pizzaoverhead: no
<whitequark> i just don't like the taste and feel
<whitequark> actually i dislike the majority of foods i ever tried
<whitequark> also food in general
<whitequark> a literal glucose IV drip would be great if it wasn't so inconvenient
<egg> o_O
<whitequark> the soylent people don't go far enough tbqh.
<egg> O_o
<whitequark> what
<bofh> so like actually I think they went a bit too far
<bofh> and put in too much Enterotoxin B
<whitequark> well yes I mean soylent not as in literal soylent
<bofh> (the RDA for that is 0ug/day)
<whitequark> but as the abstract concept, which they did not invent
<bofh> ahh
<whitequark> also from the reviews I am pretty sure it is not properly balanced
<whitequark> do they employ a nutritionist?
<whitequark> I don't actually know
<bofh> well after reading some of /r/soylent I really hope you aren't thinking that they haven't gone far enough :P
<bofh> seeing as I was afraid to joke about "well try orellanine" to the guy who complained about peeing
<bofh> for fear they might try it
<whitequark> oh cool, superoxide generator
<pizzaoverhead> whitequark: Scurvy is also inconvenient. What do you do for food currently?
<whitequark> pizzaoverhead: oh, i like fruit
<pizzaoverhead> Perfect :D
icefire has joined #kspacademia
<egg> whitequark: ahem, sorry, took me a while to dig through the reply tree in that thread, but in response to your <whitequark> what, https://twitter.com/FioraAeterna/status/815579328499027968
<kmath_> <FioraAeterna> @whitequark @oshepherd you're mad. I mean this as a complement
<egg> (though arguably that thread is a better example thereof :-p)
<whitequark> egg: lol
<bofh> whitequark: so like I still say you should write up the procedure for that in lab.whitequark.org
<egg> I was thinking the same thing
<bofh> like in detail
<egg> whitequark: though I am somewhat surprised at your aversion for food, iirc there's some cooking in that lab notebook?
<whitequark> egg: yeah
<whitequark> well uhh
<whitequark> i can just enumerate the things I like there are not that many of them?
<egg> whitequark: also, an update by phl on principia https://github.com/mockingbirdnest/Principia/issues/1237#issuecomment-285790499

<egg> Qboid stop truncating links
<whitequark> pickles, fried chicken or beef or pork if there's absolutely no fat or bone or sinew in it, potatoes (as long as they have only one phase), apples, plums, whichever thing it is that's like a middle ground between an apple and a plum whose name I don't recall, ramen, bread, jello
<whitequark> uhm
<whitequark> that's largely it
<whitequark> combinations are fine as long they are distinct phases. sauces are *not* fine
<egg> whitequark: so you don't like fat, but you like your chicken fried?
<whitequark> erm
<SnoopJeDi> http://thepotato.tech is a good thing
<whitequark> I think that word is ambiguous, sec
<whitequark> (adj) cooked in hot fat or oil
<whitequark> yeah that's not what I mean
<whitequark> I mean just heated in a pan at over 100°C
<egg> aah ok
<SnoopJeDi> pan-fried usually disambiguates that
<egg> yeah the english are terrible at food terminology
<SnoopJeDi> well, it's still frying in its own fat
<egg> and what do you mean by one phase of potatoes?
<whitequark> which fat
<bofh> whitequark: also is any phase fine?
<bofh> i.e. gas-phase potatoes okay?
<SnoopJeDi> egg, besides, the French have a word for fond and that's just silly :P
<egg> :D
<SnoopJeDi> Kenji has a propensity to refer to it as "tasty brown gunk"
<egg> SnoopJeDi: but it litterally means "bottom" (of a vessel)
<whitequark> egg: I mean they could be mashed or fried or boiled (fried potatoes are the one thing with oil i like) but you ought not boil them in their own skin
<whitequark> because that would be two distinct phases
<whitequark> bofh: sure why not
<whitequark> oh
<egg> SnoopJeDi: so it's what at the bottom of the pot
<whitequark> eggs, hard-boiled
<whitequark> and sausage, which is another incredibly ambiguous english word
<SnoopJeDi> egg, I believe the etymology is actually because it's the foundation of the sauce you build by deglazing?
<whitequark> >deglazing
<egg> déglacer
<egg> they stole that too :-p
<SnoopJeDi> wikipedia says referring to the bits as fond is a US thing so eh
<pizzaoverhead> Sausage: Minced meats of mostly animal origin in cylinder form.
<SnoopJeDi> with/without novel stress patterns that make it curl when cooked, depending on method of preparation
<egg> SnoopJeDi: a fond doesn't have large solids
<pizzaoverhead> The Scottish modify the recipe by making "square sausage"
<SnoopJeDi> yea I didn't realize "sucs" was used to refer to the material egg
<whitequark> pizzaoverhead: yeah but there are so many kinds of sausage
<whitequark> bologna sausage ≠ smoked sausage ≠ whatever is the kind of sausage you put in boiling water before eating
<SnoopJeDi> egg, but that rather proves my point about French and culinary language ;P
<whitequark> bologna sausage is seriously underappreciated
<egg> whitequark: I wonder whether you would like potato puree (that is potatoes mashed and mixed with some amount of butter), given that you do like oil in fried potatoes
<egg> (they should ideally be filtrated)
<pizzaoverhead> whitequark: Cylindrical spiced meat affords quite an amount of variation.
<egg> (so I guess that makes it very much one phase)
<whitequark> egg: I don't know if the thing you call puree is the thing I call puree so I can't answer
<egg> (well filtrated with a coarse enough sieve that you can shove mashed potatoes through them)
<pizzaoverhead> egg: Filtrated? Centrifugally separated :D
<egg> whitequark: boil potatoes; mash them; mix with butter (proportions vary); pass through coarse sieve; probably reheat if the sieving was slow and let things cool; serve with something.
<egg> (like meat or whatever)
<SnoopJeDi> with or without skins?
<egg> you peel em first
<SnoopJeDi> potato preparation that discards the skin makes me sad :(
<bofh> pizzaoverhead: related, it annoys me so much most kitchens lack an LN2 tap
* egg agrees with bofh
<egg> also should try to find a way of getting some
<SnoopJeDi> egg, there are certainly mashed potato variants with skins kept on
<whitequark> egg: come to RU
<egg> yes but that is not what I mean by puree :-p
<pizzaoverhead> bofh: You mean you don't have a dispenser on your fridge? How else do you supercool your drinks?
<whitequark> LN2 here is a waste, you walk into Курчатовский институт with a thermos flask and they are glad to get rid of it
<SnoopJeDi> you said mash not puree in the last message :P
<egg> I mean it's cheap here too iirc
<egg> recall a physics prof saying "it's like beer"
<SnoopJeDi> There's an LN2 ice cream joint in Austin that we visit occasionally whenever we trek down there
<egg> (comparing it with helium, which isn't cheap)
<whitequark> egg: LN2 is genreally cheaper than bottled water
<SnoopJeDi> It does exactly nothing for the taste
<whitequark> much less beer
<pizzaoverhead> egg: Beer eh? Tell me more :D
<SnoopJeDi> But Modernist Cuisine's perfect burger calls for LN2 soooo...
<bofh> 22:11 <@whitequark> LN2 here is a waste, you walk into Курчатовский институт with a thermos flask and they are glad to get rid of it
<whitequark> you have humongous amounts of discarded LN2 from liquefaction of air, which you do if you need noble gases or LOX
<SnoopJeDi> you sous vide the patty, dunk in LN2 to establish a thermal buffer, then deep fry to get Maillard on the exterior without cooking the interior
<whitequark> bofh: yes, they will just pour it into any provided container
<bofh> so like that's how it is at the chem lab both at my old place nad new one
<egg> I mean if I tried I could probably talk to someone at ETHZ
<SnoopJeDi> which is...waaaaaay too much work for a hamburger
<egg> SnoopJeDi: yeah I have MC
<egg> it's a good book
<bofh> like I mean I would fill up dewars at 4AM alone all the time
<SnoopJeDi> So I hear, egg
<SnoopJeDi> I'm still mastering the basics, so I mostly stick to whatever Kenji is saying on any subject (also because fanboyism)
<SnoopJeDi> Still yet to make all of the mother sauces, I think Béchamel is really the only one I've done
<bofh> egg: so once I joked about what someone would do if I vented a 500L liquid He dewar
<egg> D:
<bofh> response was something like "so we'd debate killing you, but your life insurance wouldn't be enough to pay for that"
<bofh> (I wouldn't ever actually do that)
<bofh> (good god)
<SnoopJeDi> calling a 500 L vessela dewar makes me really uncomfortable
<egg> whitequark: https://twitter.com/whitequark/status/840323838764183553 I haven't but I have MC which has recipes involving that
<kmath_> <whitequark> Has anyone tried to use a centrifuge in cooking yet
<egg> centrifuging tomatoes, or carrots, or corn, or peas or whatever
<SnoopJeDi> but I'm not sure where I'd draw the cutoff between a dewar and just "a tank"
<egg> I think there's a goulash obtained by centrifugation
<egg> or with a centrifugation step at least
<SnoopJeDi> salad spinners? :P
<bofh> ^
<egg> that's a flimsy centrifuge though
<pizzaoverhead> I'm sure at least some chicken-derived semi-meats are created via centrifuge

<egg> oh right there's not much of it https://lab.whitequark.org/notes/cooking/
<egg> whitequark: though cake doesn't figure in your list of things you like?
<UmbralRaptor> Frosting probably makes it multiphase?
<pizzaoverhead> whitequark: Part of the process of baking is drying. The closed environment of the saucepan and lid without a moisture sink may have contributed to the difficulty.
<SnoopJeDi> Baking science is fascinating. I'm still blown away by the difference a bit of water in a pan (or ice cubes) makes in the crispness of a baguette or loaf
<egg> wet bulb vs dry bulb \o/
<egg> (aka relative humidity in the oven screws with you in creative ways)
<SnoopJeDi> this year's public lecture to open the festival is the science of cooking with a Harvard prof and a local chef \o/ http://physicsfestival.tamu.edu/david-weitz/
<egg> (aka if you cook two cakes they cook faster)
<pizzaoverhead> SnoopJeDi: There is a lot happening. I find it incredible that humans have tuned it to a fine art over millennia with little understanding of the underlying processes.
<SnoopJeDi> yea pizzaoverhead, the historical implications of bread are fun to consider
<SnoopJeDi> i.e. it's very obvious how you get from unleavened bread to leavened bread, but what the heck was going on that people took a not-very-tasty plant, ground it up, mixed it with water, and put it to heat?
<SnoopJeDi> and then yea all the details of cultivating starters, kneading...
<pizzaoverhead> I was at a beer brewing course recently where I learned that beers were originally given their yeast by a "magic stick" (with yeast colony) that turns things into beer when you stir them with it.
<SnoopJeDi> active fermentation is active
<pizzaoverhead> :D
<pizzaoverhead> What's cooking?
<SnoopJeDi> that one was an extra special bitter that we christened "Brewedboi: pickitup pickitup pickitup" because we're idiots
<pizzaoverhead> :D
<SnoopJeDi> I've been meaning to get a glass carboy of my own and make some apfelwein since a friend sent me a recipe
<egg> whitequark: to expand upon your tweet: if something's not used for cooking somebody is probably working on it
<egg> whitequark: rotor-stator homogenisers have plenty of applications
<egg> vacuum filtration systems, vacuum chambers
<egg> (not just vacuum sealing that is, some preparations involve letting things cool in a vacuum
<UmbralRaptor> I'd ask about telescopes, but that's too obvious.
<UmbralRaptor> So, lasers?
<bofh> precision cooking?
<UmbralRaptor> Maybe
<egg> apparently there's some gadgety stuff to draw on toast or bacon
<pizzaoverhead> Likely laser "sintering" for 3D printed foods
<egg> not sure if there's anything more serious
<pizzaoverhead> There are some polymer 3D printing methods that use lasers for solidification if I'm remembering correctly.
* egg pokes the sky with a stick
<pizzaoverhead> egg: Careful, it might collapse into a small dome and cause a new moon
<egg> hahahaha
<egg> hmm
<egg> clear sky, some moon
<egg> and I don't feel like getting out, so this will be through the window
<egg> eh, let's see what's there
* egg turns on dim red lights
<pizzaoverhead> Window?
* pizzaoverhead googles "outside"
<bofh> yeah, and Outlook Express is even worse
<pizzaoverhead> ^ Valid for every version of Office
<pizzaoverhead> :D
<pizzaoverhead> bofh: http://explosm.net/comics/4303/
<pizzaoverhead> While I'm digging around my "sky is falling" stuff, have some KSC kitbash: http://i.imgur.com/DJneFfG.png
<bofh> pizzaoverhead: LOL
<pizzaoverhead> ...ignore the shipping crates on the launchpad
<egg> Ow the full moon through an 80 mm is bright
* egg looks for the ND filter
pizzaoverhead_ has joined #kspacademia
<egg> !acr -add:ND Neutral Density
<Qboid> egg: I added the explanation for this acronym.
<egg> hmm... basically nothing out the window but the moon; no deep sky objects of interest, no planets

<egg> UmbralRaptor: ^
<egg> wow the atmosphere is a mess
<pizzaoverhead> The Moon's atmosphere shows up well there.
<whitequark> lol
<egg> nah, but I'm staring through the eyepiece and it's blinking in and out of focus like crazy
<pizzaoverhead> Ooh
<pizzaoverhead> What kind of telescope?
<egg> redractor, achromat possibly, but not apochromat, 80 mm diametre, 300 mm focal length (v. short so still lots of chromatic aberration)
<egg> tis actually a finder
<egg> a fat finder
<egg> which I use on its own
<egg> I might get a cat
<egg> (or I might get a cat I guess? who knows)
<pizzaoverhead> :D
<egg> I want to find that photo of cats with a cat, but that's hard to google
<pizzaoverhead> It's less "hard to google" and more "not something that has been photographed before"
<egg> no there are photos of cats confused looking at a cat
<egg> UmbralRaptor: is there anything in Sex?
<egg> that's a refractor though
<pizzaoverhead> No, it's a "kitten in space chasing a taco" mousemat
<pizzaoverhead> :D
<pizzaoverhead> ...google image search for "cat telescope" is a strange place
<pizzaoverhead> Wait a minute... "silverfox"?
<pizzaoverhead> =_=
<SilverFox> ????
<pizzaoverhead> Is this your doing?
<pizzaoverhead> It has your name all over it
<SilverFox> no
<pizzaoverhead> well... part of it
<SilverFox> i hate cats
<SilverFox> also dont have a deviant art
<pizzaoverhead> Ah, so you have a motive for defacing them. THE PLOT THICKENS
<SilverFox> also my numbers are 8124
<egg> whitequark: ok, here's a hardware project, the flexible handles for this mount keep falling off :-p
<whitequark> egg: I told you about solvespace yet right?
<egg> yes
<egg> (they are mounted by tightening screws against a, what do you call that in english, a shaft whose cross-section is a half-moon (the screw presses against the flat part), and the screws unscrew themselves as you use the handles)
Wetmelon has joined #kspacademia
<egg> there's probably an easy fix by making notches on the shafts
<Wetmelon> o/
<egg> but anyway, observing time
<Wetmelon> Defnitely do that
<whitequark> egg: set screw and a D-shaft
<whitequark> I think
<egg> I gather from this map that Sex is boring (there's one galaxy in there, and that's definitely not something for this scope and sky)
<whitequark> what is boring
<egg> (bounded by Leo, Crt, and Hya, and exactly where my window is right now)
<egg> also it's cold
* egg looks for socks and gloves
<whitequark> i just turn up the air conditioner :p
<egg> whitequark: oh, were the window not wide open this would not be an issue
<whitequark> I *wish* I could live with an open window here
<egg> whitequark: but I am trying to minimize the amount of dirty glass between my eye and the sky
ferram4 has quit [Read error: Connection reset by peer]

<egg> blorg the g/are vwith that teonn kills deey sky anytoy
<bofh> so it's not as bad as Tawian, but May - Sept there's a good chance of at least one typhoon hitting inland (though they weaken to the point where they aren't dangerous by the time they're inland)
<egg> also typinf with glves is hard
<bofh> oh would it be an issue if I invite a friend into this channel? (astro master's student, fairly quiet even on irc)
<bofh> egg: that it is
<whitequark> bofh: yes I know about typhoons
<whitequark> once I was going to buy something or the like, I go out, there's light rain
<egg> bofh: 1. sure, 2. typing with gloves? yeah (I am back to freezing my hands for this message actually :-p
<whitequark> then I realize everything's closed
<whitequark> and apparently HKO has issued "typhoon warning 7" or whatever
<whitequark> it was just a bit of wind! wtf, hongkongers?!
<whitequark> and a taxi driver charged me extra. asshole.
<egg> I have *one* naked eye star in this window with the @#$%^& moon
<Iskierka> "Any sufficiently advanced technology is indistinguishable from death rays."
<bofh> egg: like okay I have thin enough gloves that typing isn't too bad, I was for some reason thinking you were typing w/mitts on which is like much worse
<bofh> whitequark: heh rofl
<bofh> whitequark: so someone I know once got caught in a typhoon that hit inland
<egg> not mitt- but leather doubled with wool
<bofh> described it as "walking through a slightly vigorous bathroom shower"
<Iskierka> ;wpn -add:wpn ray
<egg> so possible but hald
<Iskierka> !wpn -add:wpn ray
<Qboid> Iskierka: Weapon already added!
<Iskierka> !wpn -add:wpn death ray
<Qboid> Iskierka: Weapon added!
<Iskierka> !wpn -add:adj death
<Qboid> Iskierka: Adjective added!
<egg> buts thes you can eget a death tdeath ray
<whitequark> bofh: that is very accurate.
<whitequark> also I am told that while HK loves to close, SZ just over the border doesn't care.
<Iskierka> for extra death
<Iskierka> !wpn egg
* Qboid gives egg a monad
* whitequark slaps Qboid around a bit with a large trout
<bofh> TW also doesn't care despite them getting some of the strongest bits
<bofh> so I think this is just HK being uh
<egg> around alphard ut's saner with the glare
<bofh> so you know how like 1mm of osnow falls in like Texas sometimes and EVERY ROAD JAMS and places close?
<bofh> s/osnow/snow/
<Qboid> bofh meant to say: so you know how like 1mm of snow falls in like Texas sometimes and EVERY ROAD JAMS and places close?
<bofh> yeah that
<whitequark> lol
<bofh> !wpn Qboid
* Qboid gives Qboid a finite nova
<whitequark> yes, inexplicably, I know
<whitequark> despite never having been in texas
<bofh> a good chunk of California does the same
<egg> france can do that too, but they can also do that when the weather's nice
<egg> or when it rains
<egg> or really whenever
<bofh> so like once me and someone I knew from North Saskatchewan were talking with south Canada folk about how snow days work
<bofh> basically how snow days work in North Sask is they debate sending you home from school when the temperature drops from -30C to -40C and the blizzard visibility goes from 1m to not
<bofh> don't worry the students wound up having to push the bus part of the way
<bofh> to me this seems perfectly reasonable but everyone else there was like "WTF???"
<bofh> egg: I think that's just a property of France, not a property of weather.
<egg> hehe
<egg> bofh: also naming things in mathematics
* egg likes his conifers
<soundnfury> !wpn
* Qboid gives soundnfury a boiled thyme pentagon
* soundnfury gives Qboid some sage advice.
<soundnfury> (well, that's only parsley true)
<egg> ok, Hya is mostly under a roof, Sex is boring, and the moon is mmessing up all of Leo, that's it for today's observing session :-p
<bofh> soundnfury: *facepalm*
<whitequark> dear. these Apple identifiers are monstrous
<whitequark> CFStringGetMaximumSizeOfFileSystemRepresentation
<bofh> egg: I'm partial to Picea spp., you?
<bofh> whitequark: my god that's worse than NT native API
<soundnfury> bofh: *clicky* I'm afraid that palm doesn't exist. *clicky* I meant, that _face_ doesn't exist.
<whitequark> how about CFStringCreateMutableWithExternalCharactersNoCopy
<egg> bofh: hah
<soundnfury> whitequark: and then they wonder why us unix folk act so smug and superior
<bofh> (NtDeviceIoControlFile gets very irritating to type around the second time you need to invoke it)
<whitequark> bofh: or this snippet, which is typical
<whitequark> [path stringByAppendingPathExtension:[extensions objectAtIndex:extensionIndex]]]
<whitequark> or this method I had to override
<whitequark> - (BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)theApplication { return YES;
<whitequark> soundnfury: macos *is* unix, bsds and linux arent :p
<whitequark> (maybe oracle is still paying the unix fee, I don't know, FOSS ones definitely don't bother)
<bofh> so that reminds me of RtlDosPathNameToNtPathName_Ustr() (which needs a parameter initialized via RtlInitUnicodeString())
<bofh> also rofl
<bofh> there's a automatic "reap process after last visible window is closed" thing in iOS?
<soundnfury> whitequark: uh, no, just because you have a Unix layer, that doesn't make you unix.
<bofh> that seems odd
<whitequark> soundnfury: that doesn't matter
<soundnfury> The kernel is some microkernel shit, and the userland/api is some Apple shit
