<Asymptote> Hello guys, if there are any modders in here, I need your help. I'm writing my Phd dissertation about "co-development strategies in the game software industry" and I'm looking to gather data from active modders. I made an online survey : https://goo.gl/forms/1vrkPYH4az8l32sb2
<Asymptote> It takes around 10 to 15mn to complete, it's anonymous, will be a great help and I'll be very thankful!
<Asymptote> Sorry for those who have already read this message from other mod-related # , i'm doing a tour of the factory :^)
<Asymptote> Lastly, know that I'm not affiliated with Squad or T2 in any way.

<whitequark> egg: someone should hook up AGC to KSP
<whitequark> instead of the shitty excuse for a guidance computer we have now
<egg> whitequark: do you mean the stock PID crap, MechJeb, or KOS? MechJeb is getting PEG thanks to lamont, so is going to get decent
<egg> also while we're doing fun comments, I wonder who gets this comment e
<egg> uh
<whitequark> KOS
<egg> whitequark: KOS is silly, yes
<egg> whitequark: but then the AGC would also be a bit odd for more modern missions
<egg> whitequark: as for algorithms rather than arch, PEG in MJ sounds eggsciting

TonyC has quit [Ping timeout: 186 seconds]
<whitequark> mmm
* NomalRaptor ? things, and ponders giving up on having a roomate.
<lamont> well PEG needs to evolve into IGM (the algorithms AGC uses) and be more generalized
<egg> whitequark: lamont: and eventually we need to get some guidance together in principia for low-energy stuff, but that'll likely be completely independent
icefire has joined #kspacademia
<Iskierka> lamont, PEG is pretty much as-is the AGC algorithm. If you want more generalised you want EPFG
<Iskierka> (I think that was the algorithm)
<lamont> PEG has a bunch of low pitch approximations in it, the apollo IGM routines i think don’t make those approximations
<Iskierka> The apollo systems definitely had a number of approximations. The shuttle system will have significantly less
<lamont> oh
<lamont> PEG Atlas-Centaur vs. PEG Shuttle
<egg> so many PEGs

<egg> hm, who was that
<Asymptote> egg: merci, car j'allais te demander si je devais sortir l'éditeur LaTeX :p
<egg> Asymptote: il y a aussi thesis.pdf pour la version au format ETHZ, mais je prefere ma mise en page dense
<Asymptote> egg: LaTeK est très pratique pour ça
<NomalRaptor> edit LaTeX in vim. >_>
<NomalRaptor> (though MSU would rather I submit a docx than a pdf…)
<egg> (using different sectioning scheme in the ETHZ template and in mine)
<Asymptote> egg, j'ai l'impression de lire un manuel secret Bourbaki, donc clairement pas le niveau pour te lire (socioéconomiste de formation) mais est-ce que je me trompe si je dis que tes développements te servent pour coder Principa?
<Asymptote> *Principia
<egg> aucun rapport, vraiment :-p
<Asymptote> really? thought geometric graphs and triangulation would help in that matter
<egg> la formation en maths, en general, est utile pour ca, mais la recherche est ad hoc, j'ai une cinquantaine de papiers imprimes juste pour ca
<egg> c'est de l'analyse numerique
<Asymptote> Une cinquantaine de papiers publiés ?
<Asymptote> Dans des revues académiques?
<egg> euh, je pense qu'on se comprend pas
<egg> j'ai imprime une cinquantaine de papiers
<egg> pour les besoins de principia
<Asymptote> Intéressant
<egg> j'ai pas publié quoique ce soit hein :-p
<egg> Asymptote: c'est ceux qu'on voit dans la photo avec l'oeuf
<egg> Asymptote: also NomalRaptor made me write this bibliography a while back (it's woefully out of date now though) https://github.com/mockingbirdnest/Principia/blob/master/documentation/bibliography.pdf
<Asymptote> je regarde ta vidéo sur les nombres de catalan
<NomalRaptor> <_<
<egg> Asymptote: ah yes, I had a bit of free time between my MSc and getting a job so that produced that :_p
<egg> Asymptote: the video *is* related to my MSc otoh
<egg> the Catalan numbers came up oddly often in my thesis

<egg> Snoozee: an actual weapon!
<Asymptote> J'aimerais bien comprendre en quoi l'impression de papiers a pu t'aider dans Principia
<egg> parce que je prefere lire sur papier :-p
<Asymptote> Combien de temps t'ont pris ces recherches?
<egg> (et, plus serieusement, parce qu'apres ca j'implemente les methodes d'integration numerique de certains de ces papiers)
<Asymptote> Et pour être plus précis, je voulais dire : est-ce au niveau conceptuel? des données, résulats de chercheurs que tu as mobilisées?
<egg> Asymptote: c'est pas bien subdivise en "maintenant je taupine des papiers" "maintenant je code", de temps en temps je trouve un truc qui pourrait etre pertinent pour nos problemes du moment et j'imprime
<egg> des methodes, c'est de la numerique
<Asymptote> Ok je comprends mieux
<egg> plus ou moins appliquee, mais c'est en gros tout de la numerique
<egg> pareil avec lamont
<egg> lamont also did quite a bit of research for his PEG work
<egg> though you might want to talk to him in English, iirc he is also swimming in a lake of papers, if not quite a sea yet :-)
<lamont> i mostly only know ‘murican
<lamont> and yeah i’ve got a pile of papers
<Asymptote> lamont, do these papers' results helped you into writing lines of code as well?
<lamont> yes
<Asymptote> egg, je ne te demandais pas de subdiviser ton temps d'investissement à l'heure près, mais de me donner une ordre de grandeur, ça t'a pris des jours, des semaines, des mois? Tu continues à implémenter à ce jour?
<egg> Asymptote: lamont's papers were probably NASA technical notes rather than things in academic journals, due to the nature of his project
<Asymptote> *un
<lamont> yeah https://u.pomf.is/qmepvr.pdf is the primary reference i used
<egg> I mean I'm working on principia as we speak, if that's the question :-p
<egg> yeah, NASA TN
<Asymptote> How can you work on Principia and be able to write on IRC simultaneously
<egg> my powers are limitless
<Asymptote> Are you a borg drone?
<egg> I literally just made a pull request to fix a bug, #1470 :D
<Qboid> [#1470] title: Make the horizon band of the inertial navball horizon blue | Fix #1449. | https://github.com/mockingbirdnest/principia/issues/1470
<lamont> generally i’m finding NASA TN’s to be more accessable, the academic journals assume a bit too much background
<egg> lamont: that they do
<egg> which is why as I told Asymptote, the math education did help
<egg> not the specific research work I did for the MSc, but the general math background allowed me to read those papers
<lamont> and i last took a calculus of variations course 20 years ago
<egg> some of those papers find it convenient to say that this is all happening on a very fancy Lie group, which might not be helpful for the average, say, astronomer
<egg> the astronomy-specific papers are more accessible
<Asymptote> Is Qboid a bot that reports every time someone commits to the repo?
<lamont> yeah for an undergrad i took a pile of math, including grad level calculus of variations and group theory and senior level mathematical physics (green’s functions, method of steepest descent, etc)
<Asymptote> lamont, what mod are you working on?
<egg> Asymptote: no, for live repo commits go to #principia; qboid expands refs to github
<lamont> MechJeb
<egg> e.g. google/protobuf#1
<Qboid> [#1] title: Added const qualifier to iterator to enable compiling with VS2008 | | https://github.com/google/protobuf/issues/1
<egg> Qboid does many things
<egg> expand acronyms
<egg> WISE?
<Qboid> egg: [WISE] => Wide-field Infrared Survey Explorer
<egg> SPELDA?
<Qboid> egg: [SPELDA] => Structure Porteuse Externe pour Lancement Double Ariane
<egg> SYLDA?
<Qboid> egg: [SYLDA] => SYstème de Lancement Double Ariane
<egg> KZM?
<Qboid> egg: [KZM] => Кабель-Заправочная Мачта
<egg> MaDCoWS?
<Qboid> egg: [MaDCoWS] => Massive and Distant Clusters of WISE Survey
<Asymptote> lamont, have you taken after sarbian?
<egg> AAAAAA?
<egg> AAAAA?
<Qboid> egg: [AAAAA] => Association Amicale des Amateurs d'Andouillette Authentique
<egg> :-p
<egg> Asymptote: Sarbian still exists :D
<Asymptote> I know, hence my wonder
<Asymptote> :D
<egg> well you can have several people working on the same thing, it's possible :-p
<Asymptote> I can see that
<egg> (ok, maybe not if they're all parisian)
<Asymptote> Have you guys ever met in person?
<egg> nah, but I should try meeting Sarbian when I next go to paris
<egg> maybe I'll go there in august or so to synch with the paris folks for work, we'll see :-p
<egg> NK has met Sarbian once I think
<lamont> nope, never met any other mod authors IRL
<lamont> and i just contribute to MechJeb — Sarbian is just good about running an open project
<lamont> and there’s mutliple benefits of doing things this way. if i wrote my own ascent autopilot, i’d have to rewrite piles of code that would be basically the same as MechJeb
<Asymptote> egg: C'est toi qui a configuré ce bot? Quelle est sa fonction générale ici, et sur #Principia?
<egg> principia is a bit odd from that perspective since it reinvents everything orbit-related
<lamont> plus if it was my own mod i couldn’t piss off and take a KSP vacation for 6 months without the mod becoming dead (or LGG forking a “Whatever Continued” version)
<egg> Asymptote: c'est le bot de Thomas|AWAY
<egg> il est utilitaire
<egg> ok, non, ca principale fonction est la chose stupide suivante:
<egg> !wpn Asymptote
* Qboid gives Asymptote a logarithmic ㎭ protractor
<egg> a part ca, il est utilitaire :-p
<egg> lamont: see we're protected from LGG with principia :D
<egg> building it is Everest from the north face :-p
<egg> but yeah, with principia reinventing its own things for orbits and flight planning, it means it doesn't really integrate well with, e.g., MechJeb
<egg> I mean it doesn't *interfere* with it, but it doesn't integrate either
<egg> guidance for principia would likely have to be written as part of principia
<Asymptote> lamont, what does LGG stands for in the context of forking? Also, being able to delegate a task to one another - or to know that someone else is gonna take a lead anyway - seems like a benefit of open project, I guess?
<egg> lamont: speaking of which, I welcome contributions :D
<Asymptote> lamont, egg, Guys I hope you stepped in my questionnaire because the things you say here (e.g. the way you coordinate your efforts) is very valuable for my inquiry. But tell me if you're annoyed at my questions :p
<egg> I'll look at the questionnaire tomorrow maybe, right now I'll be busy sleeping
