raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Fréchet. We currently target 1.5.1, 1.6.1, and 1.7.x. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly… | <egg> also 4e16 m * 2^-52 is uncomfortably large

neph. — egg, I believe you might be interested in this lovely brand new mod. Is there any reason to believe it would conflict with Principia's camera handling?
<discord->
egg. — the save gets big, and the memory usage is even worse because some things are recomputed rather than saved
<discord->
Pteropodidae. — Would it be possible to use "checkpoint" ephemerides?
<discord->
Pteropodidae. — So integrate until something like 1970, then restart integration using precomputed ephemerides?
<discord->
Pteropodidae. — Also, as far as I can tell c++1z is a synonym for c++17
<discord->
egg. — > So integrate until something like 1970, then restart integration using precomputed ephemerides?
<discord->
egg. — that would mitigate the computation time a little bit, but the primary issue in that issue is one of storage
<discord->
egg. — the saves are chonk
<discord->
Pteropodidae. — Oh right, since you don't store history for the planets
<discord->
Pteropodidae. — Or do you?
<discord->
Pteropodidae. — > Obviously that's not very smart of us, but then the alternative of explicitly storing 72 years of history has its own drawbacks (it runs out of memory on my machine, for instance).
<discord->
Pteropodidae. — Apparently not?
<discord->
Pteropodidae. — If vessels themselves are taking up that much space then idk
<kmath>
<eggleroy> <Majiir> I really am imagining egg just drowning in a sea of papers https://t.co/P2iqkDT7CN

egg. — specifically, see the footnote in https://forum.kerbalspaceprogram.com/index.php?/topic/162200-wip151-161-17x-181-principia%E2%80%94version-frobenius-released-2020-03-24%E2%80%94n-body-and-extended-body-gravitation-axial-tilt/page/60/&tab=comments#comment-3753887
<discord->
egg. — (yes my forum posts have footnotes)
<discord->
Pteropodidae. — At this point I'm convinced Principia is less a mod and more a lab for implementing astrophysics-related papers
<discord->
egg. — yeah, a geometry, numerics, physics, and astronomy library with a KSP mod in a corner for some reason
<discord->
DRVeyl. — The KSP mod is so you can have library testers. 😉
<discord->
egg. — We roughly replicated the parameter search from the TRAPPIST-1 paper at one point
<discord->
lpg. — isn't KSP a mod for principia?
<discord->
egg. — KSP is a graphical frontend for Principia

egg. — I think pleroy preferred that they not be executable
<discord->
egg. — @Pteropodidae I think you definitely need to source rather than eggsecute the `principia_variable_override` files at least, since they set variables
<discord->
Standecco. — better without the preview
<discord->
Standecco. — @Butcher that's true almost anywhere, and it's why people go to "historical" places; that type of building just looks better 99% of the time

Butcher. — Apparently it's a grey cat thing.

Standecco. — my cat is incredibly lazy too, and he's black and white

Standecco. — he's never reacted to TV or mirrors or whatever cats usually react to either

Pteropodidae. — @egg The files are sourced, but they use the POSIX-standard `.` notation instead of the bash-speciic `source`. Should I change that?
<discord-_>
egg. — . is fine
<discord-_>
egg. — LGTM overall, will add some comments to the script and merge
<discord-_>
egg. — but also worrying about the aerodynamics bug right now

<discord-_>
Sir Mortimer. — nö 😛
<discord-_>
Sir Mortimer. — oh and there are some things that are utterly untested (hence buggy)
* discord-_
egg. — pets cat_
<discord-_>
Sir Mortimer. — and regarding DOP... i'm not sure how to do this in a way that lets the player improve his constellation based on nothing but the status indication I display in the contract. doing an accurate real life calculation would probably overdo it, unless there is something people can look at that says "do this to improve it"

Sir Mortimer. — for instance, dual frequency transmitters and stratospheric effects are pretty much out of scope
<discord-_>
Sir Mortimer. — for instance, dual frequency transmitters and ionospheric effects are pretty much out of scope (edited)
<discord-_>
egg. — I think we had discussed that already
<discord-_>
egg. — you can show eggsagerated shells of error
<discord-_>
egg. — highlight their intersections, and that gives you a visualization of the error
<discord-_>
egg. — and the rest follows naturally
<discord-_>
egg. — dual frequency transmitters make the shell thinner, this is something you can see
<discord-_>
egg. — this does require some map view visualization to be usable, but then so do things like radiation belts

Acer_Saccharum. — These things take time
<discord-_>
Acer_Saccharum. — this is the 128 from yesterday
<discord-_>
Acer_Saccharum. — I could try a 256, but I'd need to make it much larger
<discord-_>
Sir Mortimer. — Seeing what you did there I’m reluctant of generating a 256
<discord-_>
Acer_Saccharum. — I printed this on an 11x17 (A3-ish) inch sheet of paper
<discord-_>
Sir Mortimer. — Besides half the ball would be impossible o glue because of the tiny flaps, but you could just glue some paper strips on the back
<discord-_>
Acer_Saccharum. — well to go larger I'd split each strip of polygons into it's own shape
<discord-_>
Acer_Saccharum. — and print them separately
<discord-_>
Sir Mortimer. — A3 helps. Shame I haven’t got that 🙂
<discord-_>
Acer_Saccharum. — well the structural limit is probably around 1k, beyond that it might just collapse under its own weight
<discord-_>
Sir Mortimer. — ok. generating 256 faces. this will take a while.
<discord-_>
Acer_Saccharum. — is there a way to make the lines thinner?

Sir Mortimer. — it would appear so, yes

Sir Mortimer. — ^ i guess that's it

<discord-_>
AgustinCaniglia. — Its hard to reproduce since it only happened on kerbin twice when I landed sideways... Maybe it is a parts bug....

AgustinCaniglia. — Yeah.. I think principia has nothing to do with itt..... erasing commentaries...
