<UmbralRaptop> egg|zzz|egg: does https://i.imgur.com/qgGNwbB.jpg have anything misleading? Like telling the player to select tanks instead of engines?
<egg|zzz|egg> UmbralRaptop: what's a cancellation group
<egg|zzz|egg> what's a cancellation sequence
<egg|zzz|egg> why is it talking about cancellation
<UmbralRaptop> It's for the "abort" action group
<egg|zzz|egg> ... okay
<UmbralRaptop> Incidentally, this is the stock advanced construction tutorial.
<egg|zzz|egg> it uses the word "découpler" a lot instead of "larguer" which feels really weird
<egg|zzz|egg> but it might be par for the course with the original using "decouple" instead of "jettison"
<egg|zzz|egg> but somehow "découpler" feel much weirder to me than "decouple"
<egg|zzz|egg> *shrug*
<UmbralRaptop> A player misunderstood shutting down engines as cutting fuel flow to tanks, and I'm borrowing you to see if that's a reasonable mistake >_>;;
<UmbralRaptop> eggsplosive bolts
<egg|zzz|egg> UmbralRaptop: well it says "cut"
<egg|zzz|egg> it refers to a functionality called "cut", and tells you to use that
<egg|zzz|egg> I could read that as "cut the fuel lines" or "cut the throttle" or "cut the mistranslations"
<UmbralRaptop> Ah
<egg|zzz|egg> UmbralRaptop: now, in the last paragraph it clarifies itself
<egg|zzz|egg> because it says the liquid ergol engines will cut themselves, and there it's obvious that it's in the cut-the-power sense
<egg|zzz|egg> actually
<egg|zzz|egg> even there you might read it as cut themselves from the rest of the system?
<egg|zzz|egg> UmbralRaptop: but the issue isn't in this message basically
<egg|zzz|egg> it's in the engines using the word "Cut" for "shut down"
<egg|zzz|egg> UmbralRaptop: honestly the entire thing is a hot mess of terrible translation
<egg|zzz|egg> découpler should probably be séparer in general, it just feels weird
<egg|zzz|egg> cancellation for abort is WTF
<egg|zzz|egg> well
<egg|zzz|egg> i guess there isn't a word that conveys nonrecoverable emergency cancellation nicely here
<egg|zzz|egg> UmbralRaptop: e.g. launch abort/escape systems are called "saving towers" in french (same construct as lifeboat, but tower instead of boat)
<egg|zzz|egg> no reference to the launch being done something about
<UmbralRaptop> Obviously we should just use transliterated russian.
<egg|zzz|egg> UmbralRaptop: okay there is one word that is actually used by arianespace
<UmbralRaptop> hrm
<egg|zzz|egg> UmbralRaptop: https://youtu.be/PTJJ3d7OEVY?t=15
<egg|zzz|egg> UmbralRaptop: "avorté" is aborted, however its primary meaning would be in the pregnancy sense, so you would need another word with it
<egg|zzz|egg> you can't have an "abortion group", that sounds wrong
<egg|zzz|egg> here they say "launch aborted" (well, "shot aborted" if you want to translate closely)
<egg|zzz|egg> UmbralRaptop: but same for cancellation, without context this is extremely confusing
<egg|zzz|egg> you'd have to say "launch cancellation group" or whatever
<egg|zzz|egg> at which point you're running out of UI for your title :-p
<UmbralRaptop> hah
<egg|zzz|egg> "abort" sounds aerospacey enough that it's clear what it's about
<egg|zzz|egg> aside from "abort retry ignore" you don't expect to see it referring to anything
<egg|zzz|egg> "annulation" is literally "cancellation", there are plenty of things you can cancel
<egg|zzz|egg> UmbralRaptop: okay the article on LES https://fr.wikipedia.org/wiki/Tour_de_sauvetage#Un_seul_cas_d'utilisation_:_la_mission_Soyouz_T-10-1 does use "avorté"
<egg|zzz|egg> but "groupe d'avortement de lancement" still sounds very weird
<UmbralRaptop> hrm
<egg|zzz|egg> "launch abortion group" O_o
<egg|zzz|egg> UmbralRaptop: if you can go with quotes, ["aborted launch" group] might work
<egg|zzz|egg> something like groupe « lancement avorté » (or « tir avorté », but then you run into the issue of having to rewrite quite a bit of UI to s/lancement/tir/ for terminology consistency)
<egg|zzz|egg> UmbralRaptop: but then it quickly gets awkward if you quote
UmbralRaptor has joined #kspacademia
<egg|zzz|egg> UmbralRaptop: the best would probably be "groupe d'annulation de lancement", no that it's explicit that it's about cancelling the launch, not the engines or whatever
<egg|zzz|egg> but space
<egg|zzz|egg> groupe d'annulation du lancement, might as well invest in an article
<UmbralRaptor> Space is hard. Especially when you need to properly internationalize it.
<egg|zzz|egg> i18n is hard
UmbralRaptop has quit [Ping timeout: 202 seconds]
<egg|zzz|egg> UmbralRaptor: yikes, I had focused on the von kerman dialog box, but the bar on the left is really bad
<egg|zzz|egg> it says
<egg|zzz|egg> Action groups: Stage / Equipment / Lighting / RCS / SAS / Brakes / Cancel
<egg|zzz|egg> UmbralRaptor: in a UI, on its own, Cancel means a very specific thing
<egg|zzz|egg> and that's not this one
<UmbralRaptor> blarg
<egg|zzz|egg> UmbralRaptor: well, Cancel or Undo
<egg|zzz|egg> it's a word at the intersection of those two :D
<egg|zzz|egg> UmbralRaptor: so this should say "Annulation lancement" or something (except that's too long so you'll end up with "Annul. lanc." which quickly gets confusing
<egg|zzz|egg> s/lancement/tir/ would gain some space :D
<egg|zzz|egg> bofh: space french
<bofh> egg|zzz|egg: yeah I saw, still not sure why "cancellation" for abort is weird, that's what I'd translate "launch abort" as...
<egg|zzz|egg> bofh: because without context, cancel, in a UI, means something
<egg|zzz|egg> if I see a cancel button somewhere, I don't think it's going to mean "things that happen on launch abort"
<egg|zzz|egg> whereas if i see an abort button and it's not abort/retry/ignore and it's KSP, i'm more likely to interpret "abort" correctly
<bofh> I mean fair, but what would be a *better* translation of "abort" then in the context of scrubbing a launch?
<egg|zzz|egg> bofh: so "annulation" also has a sort of "softer" feeling to it, as in "oh we've decided to call it off", rather than "everything is on fire"; the arianespace « tir avorté » doesn't have this connotation for instance
<bofh> I mean that's literally the opposite of what I'd expect to be desired, generally launches are scrubbed b/c if they don't things will *be* on fire
<egg|zzz|egg> bofh: we're talking launch abort action group
<egg|zzz|egg> i.e. "fire off the LES"
<egg|zzz|egg> the "fire off the LES" button shouldn't be labeled "cancel"
<egg|zzz|egg> big red button on yellow stripes: [ CANCEL ]
<UmbralRaptor> Yeah, KSP would want the "everything is on fire"
<egg|zzz|egg> other big red button on yellow stripes [ OK ]
<egg|zzz|egg> bofh: i.e. abort in the sense of abort-implies-failure
<egg|zzz|egg> not retriable abort
<egg|zzz|egg> (which might be called hold or scrub in en i guess)
<bofh> Scrub is the term I usually hear used
<egg|zzz|egg> bofh: e.g. you wouldn't say Soyouz МС-10 was cancelled
<egg|zzz|egg> it is techniacally true that at some point the flight computer elected to cancel the mission
<egg|zzz|egg> but
<egg|zzz|egg> that's not what you'd call cancel
<bofh> LOL
<egg|zzz|egg> bofh: I mean, this does say "annulation" but by literal translation of the original figure label https://fr.wikipedia.org/wiki/Soyouz_T-10-1#/media/File:Soyuz_launch_pad_abort_sequence.svg
<egg|zzz|egg> you would not call this the launch cancellation sequence of a союуз ροχκετ
<egg|zzz|egg> rocket even
<egg|zzz|egg> *flight manual*: to cancel a scheduled launch: 1. fire the explosive bolts retaining the spacecraft to the launcher, fire the launch escape tower, open the grid fins
<bofh> rofl ροχκετ
<bofh> Also huh.
<egg|zzz|egg> bofh: i mean, would you call that a launch cancellation
<egg|zzz|egg> in en
<bofh> I'd call that a mission abort
<bofh> not a launch abort, since there is no possible way to rerun the launch (since the craft is kind of. well. yeah).
<egg|zzz|egg> bofh: well the launch abort system makes the launch unretriable
<egg|zzz|egg> it's called launch abort
<bofh> OH okay I see what you're getting at
<egg|zzz|egg> bofh: if it were called "launch cancellation system" it would be weird
<egg|zzz|egg> bofh: and with the UI-specific semantics of that word, if you pressed a "cancel" button to abort your launch and fire the LES, it would be *very* weird
<egg|zzz|egg> "Piloting is calm, on-board parameters are nominal" [OK] [Cancel]
<bofh> rofl
<UmbralRaptor> [Nominal] [Abort]
<bofh> I mean those ARE basically the two states it seems.
<egg|zzz|egg> bofh: I mean, Abort/Retry/Ignore seems to be appropriate here
<bofh> Point.
<egg|zzz|egg> bofh: UmbralRaptor: unrelated: the idea of a zonal-only selenopotential seems conceptually weird
<egg|zzz|egg> lathed-turned moon
<UmbralRaptor> hah
<egg|zzz|egg> s/thed/the/
<bofh> egg|zzz|egg: I mean a zonal-only selenopotential is sufficient for stable orbits, no?
<egg|zzz|egg> bofh: it's complicated
<egg|zzz|egg> bofh: it tends to have the right secular behaviour wrt to stability, so won't generally turn an unstable orbit into a stable one and vice-versa
<egg|zzz|egg> but short-period perturbations will be massively different
<egg|zzz|egg> including short-period oscillations of the eggscentricity
<egg|zzz|egg> and if the eggscentricity oscillates too much on a low orbit, you might be faced with non-gravitational forces that very much perturb your orbit and your structural integrity
<egg|zzz|egg> and obviously it's not enough for RGT orbits
<bofh> I mean yes, but do short-period perturbations matter if you're not trying to land or escape the selenopotential?
<egg|zzz|egg> bofh: well yes, if you're also not trying to lithobrake
<egg|zzz|egg> or trying to RGT for ground coverage reasons or whatever
<egg|zzz|egg> ;rpn 305 2 * 60 /
<kmath> egg|zzz|egg: 10.166666666666667
<bofh> I do not recommend unintentionally lithobraking, fwiw.
<egg|zzz|egg> bofh: yes, and eggscentricities oscillating on low orbits will do that to you
<egg|zzz|egg> so you need to take that into account
<egg|zzz|egg> even though the stability is often captured just by the lathe-turned selenopotential, there's a ground

<egg|zzz|egg> bofh: meanwhile in Principia: for Orbit C to work reasonably close to the real deal, we probably need degree and order 30
<egg|zzz|egg> a shittonne faster than 50, but still quite high
<egg|zzz|egg> 25 is very noticeably different for instance
<bofh> Huh, interesting.
<bofh> So I am again going to ask if it makes any sense to do degree 50 but any non-zonal harmonics from degree >15 are unused.
<bofh> i.e. degree and order 15, then zonal-only to 50
<bofh> (with the actual cutoff being possibly different depending on things)
<egg|zzz|egg> bofh: hmph, we haven't actually written any code to take advantage of pentagonal harmonic coefficient matrices
<bofh> pentagonal?

<egg|zzz|egg> for comparison the Grimm et al. paper reaches χ² = 342.29

<bofh> it turns out convergence is useful!
<UmbralRaptop> Strange, but true.
