<stratochief> oh right, different perceived G at each end of the teather because of where ever the COM falls. man, crazy stuff
<stratochief> xShadowx: it went haywire when I tried to make it one docked vessel at that high of a rotation :)
<xShadowx> stratochief: why would one make wire out of hay
ferram4 has quit [Read error: Connection reset by peer]
<xShadowx> also measure rotation speed, and distance from CoM, see if the perceived G is correct
ferram4 has joined #RO
<stratochief> that would require calculating where the CoM is. I'll trust the computer to do basic math right :)
<stratochief> but it sticks together well when I spin it up to simulate Earth or Martian G
<stratochief> next experiment will being trying to reproduce the same thing in RSS/RO, but that won't be tonight

<stratochief> every space program continues to disappoint me; no human artificial G experiments since Gemini, at that was at like 0.005 G
<SirKeplan> sometimes it feels like they lost any sense of imagination after Apollo era.
<SirKeplan> disapointing that all space stations have been made out of cramped tubes since Skylab too :P
<blowfish> There was a proposal at one point to reuse Space Shuttle EFTs as station modules wasn't there?
<xShadowx> stratochief: im betting the Gs a kerbal feels is based on CoM of hopefully the part, else worse the vessel CoM, both being incorrect, and i dout its using seat position x.x
<xShadowx> sure its all slight details and not a big diff but still :P
<blowfish> KSP physics are mostly part based rather than vessel based, so I would expect part CoM
<xShadowx> reason im thinkin vessel, is pod > girder > pod, spin, atleast around 1.1 it wasnt showing them under G forces as no movement
<xShadowx> but still incorrect either way heh

<egg|principia|egg> stratochief: zilti: barring big bugs, we should be looking at a release at the new moon; we'll switch to a more regular release cycle after Cardano, new moon = new release
<zilti> I tried it, but it misplaced my ships on the launchpad (ships were about 20 meters off) and as soon as I left the atmosphere I had baad lag :\
<egg|principia|egg> releasing whatever we have at that point
<zilti> Nice to hear
<egg|principia|egg> zilti: principia#1244 I gather?
<Qboid> [#1244] title: Is there a commit I can build that will work with 1.2.2? | I was wondering if there's a commit that'd work with 1.2.2. I know how to build the project, and already tried building both the latest commits in the master and Cardano branches. The Cardano behaves ... | https://github.com/mockingbirdnest/principia/issues/1244
<zilti> egg|principia|egg: Heh, yes ^^
<egg|principia|egg> zilti: so, principia#1258 should have fixed the bad lag (ooops)
<Qboid> [#1258] title: Profile kraken | It is not a good idea to go through all the objects at 50 Hz. | https://github.com/mockingbirdnest/principia/issues/1258

<zilti> Heh, nice commit message :P
<zilti> I'm probably gonna try to find out how to compile that behemoth on Linux tonight
<egg|principia|egg> hmm, not sure it builds on Linux, it's been a while since we've run clang on it
<egg|principia|egg> but we've reconverged Cardano -> master, and tests pass on Windows
<zilti> Well, then I'm gonna throw bugs at you :P
<egg|principia|egg> (and lint passes too)
egg|principia|egg is now known as egg
<zilti> Heavens, that docker file is *old* ^^ Well, I'm gonna try the next days, and maybe let you know in case I stumble over some problems (and hopefully solutions to these)
<egg> zilti: so, I don't actually use the docker file
<egg> zilti: there's the Vagrantfile, which I use to spawn the VM that builds principia
<egg> that should work
<egg> also I extensively reworked the makefile some time ago; it works on that setup, not sure how it will fare in others
<egg> stratochief: oh and that's cute too http://i.imgur.com/WfmezB4.png
<egg> launched into the wrong plane to get to the moon, did a transfer in that plane, let the moon help me out of my plane a bit
<stratochief> egg: does it wander into lunar orbit, then wander back out? cool, but a bit scary to me :P
<egg> well eventually I circularized
<egg> mind you this is a shitty transfer but it was fun seat-of-the-pants stuff
<egg> also that circularization was too high, so the thing ended up crashing because of Kerbin perturbation
<egg> (like within half a Kerbin year)
<stratochief> egg: which is awesome, because that is what happens to real lunar orbits, right?
<stratochief> or is it mostly mas-cons of the Moon that cause lunar orbitting things to crash?
<egg> stratochief: well, real Lunar orbits are worse
<egg> see that's because it's a high orbit
<egg> so you get screwed by Kerbin even though the Mun is a point mass
<egg> but low orbits are safe for now
<stratochief> egg: ahh. but for RSS, both Earth and the Moon aren't as point masses, correct?
<egg> when we get mass cons, they will be killers too
<egg> stratochief: they're just oblate
<egg> so nodal and apsidal precession, but that's it
<egg> eventually we'll add higher harmonics and have fun :D
<stratochief> egg: ahh, so for Principia there aren't mass cons, higher harmonics for the Moon yet?
<egg> nope, just J2
<stratochief> egg: in theory is Principia a framework that could support atmospheric drag from outside the stock atmosphere, if it was coded correctly to co-exist with principia?
<egg> it would have to be written *as part of* Principia
<egg> but it's eventually planned, any century now
<stratochief> egg: lol. well, I'm highly considering helping the maker of Orbital Decay produce more accurate decay for elliptical orbits, if anybody ever gets back to me on that thread
<egg> yeah, so that mod isn't compatible with Principia, and it also plans to have n-body gravitation on its own? so really they're pretty much alternatives
<stratochief> and once I have a half-decent understanding that I'm approximating that right, I could probably do my best to bend that into Principia
<egg> stratochief: I mean you can't bend anything into principia if it relies on the concept of orbit, for instance
<stratochief> egg: they 'plan to', but Orbital Decay doesn't appear to be under active development, while Principia is
<egg> so if your drag thing deals specially with eccentric orbits, that's probably a red flag
<egg> what you want to do is just integrate some drag force
<egg> but mind you, that's a nonconservative contribution, so you'd have to switch integrators when you get to regions where it matters
<egg> so you'd want to have a smooth cutoff thingy too
<egg> that way you can get back to the symplectic goodness once you're far enough
<stratochief> egg: yeah, indeed. Orbital Decay currently approximate drag in a decent way, for circular orbits. it fails abysmally for elliptical ones
<egg> stratochief: I would expect that the best way to do drag would be to happily ignore this mod, and do it in principia independently
<egg> ... also licensing, yet another person using CC for code
<stratochief> 'best' is a mixed bag. I can probably improve Orbital Decay massively in a weekend, while doing anything to Principias standard would take me ~10x as much time
<egg> stratochief: you cannot make Orbital Decay work with principia in a weekend
<egg> or in a month
<egg> they're fundamentally incompatible
<stratochief> indeed. and I -know- I can improve Orbital Decay with my existing skills, in a reasonable amount of time. I'm not at all certain I could make something that worked inside principia, given infinite time
<egg> stratochief: you can't make orbital decay work with principia, that's just what I'm saying
<stratochief> so, the Orbital Decay process for me would be to improve my understanding of decay, calculating and approximating it sufficiently to even consider attempting to approach it from the Principia direction
<egg> how does orbital decay approach approximating things though? does it integrate?
<egg> if it doesn't, and does a per-orbit approach, this is an approach that doesn't even theoretically translate to the way you'd have to do it with principia
<stratochief> I know enough about calculus and code to understand how the approaches are different, and fundamentally incompatible. the basic learning from the simple one will improve my chances of succeeding at the complex one
<egg> I'm not convinced by that second sentence though
<egg> they're really unrelated approaches
<stratochief> no, it doesn't do 'per orbit'. but it doesn't perform proper integrals/integration either
<egg> what does it do then?
<stratochief> I don't mean to convince you beyond reasonable doubt, I'm just explaining what I am intending to do :)
<stratochief> I mean, you might see how all that abstracts to proper integration, but I don't
<egg> stratochief: I mean, you do what you want, but the thing is that is not going to teach you anything remotely useful if you ever want to do it your way
<stratochief> In contrast, I -know- it will, so you'll simply have to accept that we disagree on that :)
<egg> I suspect you don't really understand at all how principia does things, if you think that :-p
<egg> literally none of the calculations done here are relevant to the principia approach
<egg> you'd be better off looking at FAR's code or somesuch
<egg> (or if you want to contribute to principia eventually, looking at the principia codebase and familiarizing yourself with it, because this takes a lot of work)
<zilti> egg: Ah so you ditched Autotools from Principia and went for plain Makefile instead?
<egg> I don't think we ever used autotools?
<zilti> The install_deps.sh says otherwise :P
<zilti> Ahh no that's for a dep, sorry
<egg> that's possibly to build a dep
<egg> I tried bazel, but it doesn't like our unicode filenames
<egg> so for now it's makefile
<zilti> I know Autotools quite well, so if you would use the result, I could work on it. While I'm building it for at least Linux using Docker anyways.
<egg> meh, I'm fine with the makefile we have
<zilti> What's bazel btw?
<egg> !g bazel build
<Qboid> egg: https://bazel.build/ [Bazel: Home] (14900 results found, took 0.77s)
<zilti> The Dockerfile seems to work btw. At least it's still running
<egg> zilti: I'm not sure what it's for or what it does

* Qboid gives stratochief an atomic bundle
<zilti> Dear heavens...
* stratochief places the atomic bundle inside a graphite cupboard for safe keeping
* stratochief attempts to give egg empathy
<egg> empathy?
<egg> why?
<zilti> "Separable algebra" is such an obscure term, there's not even an article on the German wikipedia about it ^^
<egg> zilti: well, Qboid generates things from adjectives and nouns
<egg> so it probably made that up (and it happens to be a thing because mathematicians)
<stratochief> egg: so you can do a better job of convincing others of your ideas, rather than just loudly convincing yourself that you are right
<egg> stratochief: grump
<egg> zilti: yup
* zilti closes browser tab
<egg> stratochief: well, so, I'm not sure what your ultimate aim is here: if it is to understand how decay works, sure, play with maintaining that mod; if it is to contribute to principia (to add decay), that's not going to be very helpful (and there are likely much bigger hurdles, like understanding our mad libraries, familiarizing yourself with modern C++ if you don't use that already, etc., and on the physics/math side of thing,
<egg> specifically studying how to compute drag at low densities)
<egg> stratochief: much like to implement oblateness (J2), knowing about or understanding these equations was of no use to me https://en.wikipedia.org/wiki/Nodal_precession#Equation
<egg> they're approximations that are nice to work in something that *has* oblateness, but are utterly irrelevant to *implementing* oblateness
<stratochief> egg: I will gain some better understanding of aero drag in low density air in parallel to working on Orbital Decay things
<egg> stratochief: right, but for principia purposes that's basically digging up one equation; most of the work is doing programming and design, so if your aim is to contribute understanding modern C++ is the major thing to do (and our libs, because there's like 50 kilolines of the stuff)
<stratochief> I understand that they are entirely different routes to achieving drag, but having two 'ways of doings things' and looking at them in parellel is a particularly effective way for me to learn about the more complex one etter
<egg> stratochief: again, if you just want to familiarize yourself with the physics of working in a world that has drag, that's a fine way to do things; it's just not measureably going to help with having it in principia
<egg> because if I want to do the background research to have the physics/equations for that, I can have them written on a sheet of paper by sundown
<egg> the work is all programmind & design, to knot that through our libs in a good way
<egg> stratochief: btw, if you *are* interested in getting familiar with the principia libs, I can probably find small starter projects for you to write (tests of astronomical scenarii are generally a good way to approach that, I did that with UmbralRaptor; maybe you could do solar egglipses or somesuch)

<soundnfury> RO needs you to not get sucked down the principia rabbit hole :P

* soundnfury gives egg a mock turtle, a jabberwock, and a white king that resembles a kitten
<zilti> A Kingtten
<egg> zilti: depends on the lecture
<egg> my math lectures at ETHZ were on the whole quite interesting

<egg> yes, I do that quite often

<egg> ok greeninggalaxy says I should eat >_>
<zilti> I had a huge thick brownie with nuts in it for "lunch" ^^
<stratochief> egg: or, wine and baget
<zilti> stratochief: See, that's what intimidates me a bit because I don't know it yet - that basically "calculating with infinitely small things"
<egg> stratochief: well, unless you can compute it formally
<stratochief> zilti: don't know calculus? what are you, a zygot? :P
<egg> in which case that's likely to be far more accurate
<stratochief> egg: sure, but that is only possible for problems with analytical solutions, or something, right? anything with more than 2 bodies gravity wise can't be done formally, I had thought
<zilti> stratochief: Maybe? I dunno :P
<stratochief> zilti: for me, the breakthrough to calculus came from graphs, and the fact that ultimately basic calculus is silly simple, easier than Trig, and intro physics is a great place to see calculus in action
<egg> stratochief: sure; though everything is complicated (in the Wisdom-Holmann splitting you use Kepler between steps to help with the dominant solar term on the planets)
<egg> yall need to get into kspacademia and I should prepare a course on symplecticity with that thing whitequark linked me :-p
<egg> but in any case foodtime

<stratochief> egg: I keep academia on the other side of the event horizon from me; thar be dragons
<stratochief> we record episodes of gameplay, egg should record lectures, with a blackboard, lab coat, science and er'thing
<zilti> I'm maybe simply an autodidact. I've yet to see a bachelor computer science lecture about something I didn't teach myself years ago
<zilti> (then again, we didn't come across C++ templates thankfully)
<stratochief> zilti: around third and fourth year, most programs specialize and offer things you didn't already know. at that point, it ends up being your fault for not picking the right classes
<stratochief> why pick optional classes about stuff you already knew, after all
<zilti> stratochief: yes, it's going to specialize in masters classes
<zilti> stratochief: I wish those were optional... It's all mandatory in bachelor's, you gotta do all lectures.
<stratochief> if your university doesn't offer optional specialized courses during undegrad, you're at the wrong university for your specialization IMO :P
<waerloga> ^
<waerloga> hell, mine had some starting the second year for some stuff
<zilti> stratochief: well, it's considered one of the better ones for computer science, maths and especially astrophysics in Europe :P
<waerloga> my uni had a bachelors of science in physics that specalized in astrophysics
<stratochief> considered does not equal equals :P
<egg|nomz|egg> zilti: if you want templates, have a look at principia :D
<egg|nomz|egg> template porn everywhere \o/
<zilti> (there's stuff from my uni on the moon and on the rosetta vessel)
<stratochief> zilti: what is your specialization?
<waerloga> fun thing was the overlap in classes....only 3 "extra" courses to end up with a triple degree in computer science, physics, and math
<stratochief> zilti: my definition of a good university is simple, "it taught me stuff I didn't already know, and did so well"
<waerloga> also consider what they may be teaching, or what you should be learning anyway, isn't always what the course is directly about
<zilti> stratochief: just computer science. Specialization is in master's. In bachelor's we have everything from assembler over boolean algebra, circuitry up to "normal" programming and a software engineering training
<stratochief> although university and uni students have it hard these days, so many good educational resources exist online for free now
<stratochief> zilti: in that case, by specialization I mean "obscure/narrow enough shit, you wouldn't have learned it beforehand"
<zilti> At this point I'm not even sure if I'm gonna finish uni, since I lucked out with getting a software engineering part-time job. Otoh, master's going to get really interesting when I finally reach it
<stratochief> zilti: why not both? part time masters while working?
<zilti> Because I learn much better on my own. I kinda don't see the point of forcing myself to absolve a strict timetabled programme with weekly weird assignments when I can have fun learning the same stuff on my own by participating in little and not-so-little projects
<zilti> stratochief: That's what I did when I wanted to learn a new programming language and how to efficiently parse and write a data format: https://bitbucket.org/zilti/edn/src/be5d7fec2289c9ccd1e311394570712aa9d67e91/edn-impl.scm?at=default&fileviewer=file-view-default
<stratochief> yeah, as long as you can find projects you find engaging and interesting outside of academia, that seems fine. it is't like CS academia won't still be there if you ever consider checking in on it later :)
<egg|nomz|egg> zilti: why learn CS at uni if you can do so on your own though? why not do something else at uni?
<waerloga> some of the best programmers I know have degrees in...other things...
<waerloga> best QA person? english degree
* egg|nomz|egg MSc. math
<stratochief> zilti: what language is that?
* egg|nomz|egg likes math, but couldn't have learned quite that much of it on his own
<egg|nomz|egg> whereas programming and enough CS to get by is quite doable
<zilti> stratochief: Chicken Scheme, an implementation of Scheme. Though that code should be implementation-agnostic and adhering to R7RS of Scheme
<zilti> egg|nomz|egg: I already have the pleasure of having to do 20 ECTS in Maths together with the mathematicians :)
<zilti> Astrophysics would be an interesting thing though. Especially since my uni is top-notch in that field
<egg|nomz|egg> zilti: yeah, but that's not a lot, and a lot of it for CS people isn't all that interesting :-p
<egg|nomz|egg> zilti: e.g. for some reasons CS people don't do numerics O_o
<egg|nomz|egg> so they have no idea how to into floating point (and then they write code that does floating point things and they fall flat on their face)
<egg|nomz|egg> [insert rant here]
egg|nomz|egg is now known as egg
<zilti> egg|nomz|egg: But it's a start :P I especially liked how in the very first hour of the first maths lecture what we did was look at the lemmas of very basic maths. Like addition, subtraction and stuff.
<zilti> Finally getting to look behind the curtains instead of stupidly learning some formulas to apply in the next exam
<stratochief> I'm happy not looking behind the plus sign. I trust him to be an upstanding, honest guy :)
<zilti> egg: Ugh, yeah. I mean, maybe I'm overly cautious, but I wouldn't use a float anywhere where I need actual precision
<egg> zilti: well, that approach has its own problems, but at least you know your incompetence when it comes to the realm of the Dark Lord Kahan
<zilti> stratochief: well, we have it on our flag, so I kinda have to :P Jokes aside, plus is one of the fundamentals without anything behind it. It's just a fundamental basic rule and everything is built on that
<zilti> egg: but yeah, I'm aware of how floating points work on the "metal level"
<egg> yeah, but that's semi-useless in practice :D
<zilti> Well, it's how you know where it gets imprecise, and why
<egg> knowing about guard bits and sticky bits doesn't help; once you know that the operations are exact then rounded to whichever mode that's what you use
<egg> and in fact you tend to use higher-level properties
<egg> (that's principia's integrators btw)
<egg> (all 37 symplectic & conjugate symplectic integrators of principia)
<zilti> So, gotta go home Soo, gotta go home now. Thanks, and later!
<egg> \o
<stratochief> zilti: now that you know all the gears and levers behind the plus sign, when does that simple rule not work for me?
<stratochief> I like to learn the behind the scenes workings of things, but only when a more complex understanding will benefit me
<stratochief> Probus: thanks :)
<stratochief> I do wish the technical broadcast showed the speedometre though
<Probus> Yeah, it really should.
<stratochief> and in m/s :P

<zilti> egg: The "latest" they have is completely different and from 3 years ago...
<egg> uuuuh wat
<egg> zilti: the one we're using is this one, right? https://atlas.hashicorp.com/ubuntu/boxes/wily64
<zilti> egg: Interesting...
egg is now known as egg|nomz|egg
<egg|nomz|egg> huh, no idea
<stratochief> Rokker: what are the odds of all of them actualy occuring this week, and succeeding?

<zilti> The Ariane is kinda a weird rocket. It's the only one where you get a feeling of how massive it is when you see it on a picture. Must be something about the proportions.
<stratochief> ariane, like the shuttle before it is a 'uge hydrogen tank with 'uge SRBs to toss it above the atmosphere, where hydrogen engines belong
HypergolicSkunk has joined #RO
<riocrokite> imho ariane is most similar to titan 4, new ariane 6 will be most similar to H2-A
<riocrokite> taking into account proportions between srbs, tank and fairing
<Rokker> riocrokite: interesting idea, how so?
<Rokker> riocrokite: the boosters?
<Rokker> ignore that
<Rokker> riocrokite: connection cut out before that second bit
<stratochief> wasn't the titan 4 solids, then hypergols, then LH2 for the upper?
<riocrokite> yah
<riocrokite> also inb4 titan - ariane not completed human rated versions https://s-media-cache-ak0.pinimg.com/736x/7b/8f/eb/7b8feb54f0f8ef8c26e7a255ab1cc956.jpg

<zilti> waerloga: well, the soviet rockets are reliable :p
<zilti> egg|nomz|egg: I changed the Vagrantfile to Ubuntu Xenial, that one's working ^^
<stratochief> zilti: you can always rely on a crewed Proton or N1 :)
<stratochief> in russia, either you R-7 or you R-dead
<zilti> Well, in russia, you R-7, in the US, you *were* seven :P

<xShadowx> i find it funny google is full of benchmarks of ryzen vs i7, but all use 'older gen' i7 in the tests XD
<zilti> Well, that's because there's about zero difference from last to current gen i7
<xShadowx> uhhhhhhhhhhhhhh no
<zilti> And last gen is cheaper, so they're more comparable to Ryzen
Wetmelon has quit [Ping timeout: 206 seconds]
<zilti> Between the 6k and 7k Core i7? Yeah, what was it, 2%?
<riocrokite> xShadowx: pulled the trigger on ryzen
<xShadowx> oh 6k to 7k sure

<xShadowx> im seeing ryzen vs 3k and laughin
<riocrokite> won't get good fps but for my productivity needs its perfect :)
<xShadowx> if only games would get more multithreading in :P
<riocrokite> KSP won't ;)
<riocrokite> still should be a bit better than my 3.6 xeon
<xShadowx> ksp partway does but ya too late for ksp
<xShadowx> even if ksp did get full multithreading, imo itd prolly kill ksp as so many mods would likely break too
<riocrokite> lol
<xShadowx> without mods ksp is .....<checks this isnt kspo> shite :P
<riocrokite> speaking about ksp as a physx fps limited game I wonder how APE guys are doing
<riocrokite> not much changed for a couple of months on their website
<xShadowx> my only dream for ksp atm is to get vive controllers to work on an eva kerbal to move kerbal hands, then add rcs ability to said hands, then see in a practical test how well you can iron man mode it during eva :3
<riocrokite> interestingly unity guys responded that physx offers similar mechanics under 'articulated joints' tab but it's much more cpu demanding
<Probus> Interesting
<riocrokite> i mean physx guys, not unity ones
<zilti> *sigh* ok, I give up trying to compile Principia on Linux...
<egg|nomz|egg> huh?
<egg|nomz|egg> it builds here
<zilti> Can you share the binaries for me? :D
<egg|nomz|egg> on the new moon :-p
<egg|nomz|egg> zilti: see that's the thing, principia must be built on a new moon
<egg|nomz|egg> :-p
<zilti> I can simulate a new moon :-P
<zilti> But seriously, how did you do that?
<regex> new Principia?
<egg|nomz|egg> zilti: make release?
<egg|nomz|egg> regex: we've decided on a release every new moon
<regex> nice
<egg|nomz|egg> barring new bugs, starting on the next new moon
<regex> is the next one Cantor?
<regex> the one with Axial tilt?
<egg|nomz|egg> no that's the current one
<egg|nomz|egg> the next one is Cardano
<egg|nomz|egg> with axial tilt
<regex> *\o/*
<egg|nomz|egg> and enforcement of the laws of conservation
<egg|nomz|egg> by the eggsecutive power
<xShadowx> axial tilt of planets/moons?
<regex> awesome!
<xShadowx> real axial tilt? not texture fakery?
<regex> yes
<regex> Like, seriously, asking egg whether he used "texture fakery" is kind of insulting.
<UmbralRaptor> egg is a mathematician, not a game designer. =P

<ale260382> does anyone have any idea why my rcs have two "engine - show gui" buttons in vab ?
<xShadowx> because 2 of a partmodule (unsure which) are on said part likely due to a mod / MM script mixup
<ale260382> yep
<ale260382> but what two modules ?
<xShadowx> someoneknowing buttons can prolly tell you which easier, but if you dont want to wait - see MM cache > search part name > see which modules listed for said part
<ale260382> mm thanks i didn't think of that
<xShadowx> after that its a fun trip to browse ksp.log / MM scripts adding said partmodule
<xShadowx> if you're wanting to fix anyways
<ale260382> i think i did that thing various times in the past
<ale260382> i just forgot ;)
<Rokker> how much does your first orbital manned mission typically cost in RP-0, guys?
<xShadowx> 2 kerbals, and the tears and hopes of 14 children
<stratochief> xShadowx pays the 'Iron Price"
<ale260382> mm in effect, the rcs has a duplicate ModuleEngineConfigs
<ale260382> similar but slightly different, IE syntax is slightly different, one has cavea-b one has not
<soundnfury> Rokker: about 100k to unlock mercury pod and bits, maybe 10k for the rocket, another 10k for a test flight with an Able core playing the role of "Ham" the chimp
<soundnfury> the point being, next to the part unlock costs, the actual vehicle is cheap
<Rokker> soundnfury: I'm spending like 5.5 k on my rocket but I feel like I could be doing it cheaper
<soundnfury> nah, that's pretty good (if it includes the capsule)
<Rokker> stratochief: ready for the launch?
* soundnfury usually just builds a (FASA) Atlas
<Rokker> soundnfury: I'm basically sticking an X-1 cockpit with a heat shield on top of cancer in rocket form
<ale260382> btw got it, installation issue
<ale260382> ckan forces installation of realfuels stock configs with realfuels
<Rokker> soundnfury: can you like Dropbox or Google Drive me the fasa bit of your install, because I remember all of my attempts failing on load
<Rokker> and just gave up on it
