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
<discord-> p​olyatomik. — idk if it is principia doing this, but i get these weird random orbit lines that flash around when in map view
<discord-> p​olyatomik. — anyone know how to fix this?
<discord-> l​pg. — that's stock, and in fact is something recent versions of principia should be fixing
<discord-> l​pg. — (by hiding the orbit lines altogether)
<discord-> p​olyatomik. — ah, so its not fixable currently 😦
<discord-> l​pg. — no I mean it _is_ "fixed" in latest principia versions
<discord-> p​olyatomik. — you can see it
<discord-> p​olyatomik. — ah i guess im using an older version
<discord-> l​pg. — I see a line, I couldn't say if it's what I'm referring to
<discord-> p​olyatomik. — do u like how my earth looks though, just wondering
<discord-> p​olyatomik. — where could i improve on it
<discord-> M​yshiko. — Latest Principia is good

<discord-> B​utcher. — @polyatomik I'd say your Earth is oversaturated.
<discord-> n​eph. — It does appear somebody spilled an awful lot of paint
<discord-> B​utcher. — Or the atmosphere has been burned off so there's no scattering.

<discord-> e​gg. — please do not burn the atmosphere
<discord-> B​utcher. — Pfft, spoilsport.
<discord-> D​RVeyl. — But burning the atmosphere is great. All that fuel you didn't have to bring with you!
<discord-> D​RVeyl. — Unpressurized storage density probably sucks, but plenty of volume.

<discord-> M​yshiko. — @DRVeyl gravitationally walled fuel tanks, I like them.
<discord-> K​irk. — Terrible mass ratio though
<discord-> M​yshiko. — Just add antimatter 🙂
<discord-> M​yshiko. — Just add antimatter 🙂 for the complete bi-propellant system (edited)
<discord-> e​gg. — OK looks like I have a prototype of Principia persistent rotation that properly exhibits the Джанибеков effect (contrary to PersistentRotation)
<discord-> M​yshiko. — count me in!
<discord-> e​gg. — looks like the vessel gets teleported on the other side of the planet when you dewarp though
<discord-> e​gg. — technicalities
<discord-> e​gg. — at least it rotates correctly :-p
<discord-> M​yshiko. — Ship it, we will call it EGG effect 🙂 - teleport on dewarp.
<discord-> B​utcher. — What is the Джанибеков effect?

<discord-> B​utcher. — That is some funky stuff.
<discord-> B​utcher. — Will it make any manoeuvres harder? I assume spin stabilised rockets are rotating around their first principle axis typically, so should be stable?
<discord-> M​yshiko. — @Butcher witches everywhere 🙂
<discord-> e​gg. — @Butcher it will mean that spin-stabilized things should remain spin-stabilized
<discord-> M​yshiko. — As long as earth does not flip like that, we should be fine.
<discord-> e​gg. — but obviously things that spin out of control in a chaotic way will remain chaotic :D
<discord-> e​gg. — Earth doesn't do that; some asteroids do
<discord-> M​yshiko. — I feel better already
<discord-> B​utcher. — @egg more stable than with PR?
<discord-> e​gg. — well, PR doesn't actually preserve angular momentum, so it might lead to weird drift
<discord-> M​yshiko. — I’m not a big fun of PR
<discord-> e​gg. — as long as you don't touch your reaction wheels or thrusters, we will enforce the constancy of L
<discord-> M​yshiko. — I’m not a big fun of PR, so would be good replacement (edited)
<discord-> A​cer_Saccharum. — no more wobbly rockets leading to tumbling?
<discord-> e​gg. — in the same way that there's no difference between warp and non-warp for the trajectory of your vessel in Principia as long as you don't thrust, there will be no difference between warp and non-warp when it comes to angular momentum (nonrigid effects may lead to oddities, but the angular momentum will be conserved)
<discord-> A​cer_Saccharum. — very nice
<discord-> e​gg. — @Acer_Saccharum nonrigid effects may lead to oddities, as in real life
<discord-> e​gg. — if your rocket is wobbly, you will have problems
<discord-> e​gg. — but that's true in real life
<discord-> A​cer_Saccharum. — well I was more talking about wobbly part joints in KSP being weird
<discord-> A​cer_Saccharum. — I do know Explorer 1 began tumbling mere hours after launch
<discord-> e​gg. — I don't touch joints
<discord-> A​cer_Saccharum. — due to the flexible antennae dissipating angular kinetic energy
<discord-> e​gg. — I won't touch joints
<discord-> e​gg. — so if they do wobble, they will wobble
<discord-> e​gg. — (except in timewarp where I'll assume that the vessel is rigid)
<discord-> A​cer_Saccharum. — honestly it'd likely only cost your your sanity trying to deal with the default or KJR joints

<discord-> e​gg. — @Acer_Saccharum yeah but my sanity has already been spent, so I can't afford that
<discord-> e​gg. — @Butcher I suppose? I mean, in terms of gameplay I'd assume that this would be largely similar to PersistentRotation
