egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <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…
<queqiao-> ⟨egg⟩ Is the bridge working?
<queqiao-> ⟨egg⟩ Apparently.
<queqiao-> ⟨egg⟩ Oh, but there was a netsplit, so the notifier isn’t there.
<paculino> Has the notifier failed before? I don't remember that happening.
<queqiao-> ⟨egg⟩ Not sure if it has failed, maybe it is just stuck on the wrong side of a netsplit.
<queqiao-> ⟨egg⟩ The logs say raptop was split for several hours.
<paculino> _whitelogger is still showing as connected for me
<queqiao-> ⟨egg⟩ yes, but that is the logger. The notifier is _whitenotifier-[some hex]
<paculino> Oh. That is offline.
<raptop> Yeah, there was a major netsplit
_whitelogger has joined #principia
<queqiao-> ⟨gh0st⟩ i have no clue what I'm doing, but that's half the fun
_whitelogger has joined #principia

<queqiao-> ⟨sichelgaita⟩ PSA: We have had reports that vessel targetting was broken in the new release (ابن الهيثم). Our best engineers are currently investigating.
<queqiao-> ⟨Vlood⟩ One has to wonder if "our best engineers" is code for "our cats" on this channel
<queqiao-> ⟨egg⟩ Notifier still either down or split, bridge still up.
<queqiao-> ⟨egg⟩ https://github.com/mockingbirdnest/Principia/issues/3653 is the bug report.
<queqiao-> ⟨Damien⟩ ⟪egg⟫ Who reviewed <https://github.com/mocking[…] ⮪ _it is terrifying that this compiled._
<queqiao-> ...
<queqiao-> ...
<queqiao-> _we have a new bug_
<queqiao-> ⟨Damien⟩ 😄
<queqiao-> ⟨egg⟩ Unrelated, I think. The commit that introduced the bug is _what the hell_
<queqiao-> ⟨sichelgaita⟩ A new version of ابن الهيثم is now available which fixes https://github.com/mockingbirdnest/Principia/issues/3653. Please go to the README and download it again from the links there.
<queqiao-> ⟨KrazyKerbal⟩ Lagrange points! Equipotentials!!!! I'm absurdly excited that its' finally here
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ extended body gravitation refers to the fact that the body is not a point mass, right?
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ Also, how is that implemented in principia? multiple points, or something more advanced?
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ +I was always curious about that
<raptop> egg plays the music of the spheres with math
<raptop> (joke aside, spherical harmonics)
<queqiao-> ⟨Basila⟩ i don't know how it was made but it works. SSO is real and gives much dopamine as well as ballistic capture 🙂
<queqiao-> ⟨Damien⟩ ⟪🇺🇦 Katniss 🇺🇦⟫ Also, how is that implemented in […] ⮪ the one thing you can trust when it comes to eggdev, is that shortcuts are haram
<queqiao-> ⟨Damien⟩ I don't doubt that the gravity model of earth is 1:1 with actual earth
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ ⟪raptop⟫ (joke aside, spherical harmonics) ⮪ Oof, I guess I have another thing I can learn about
<raptop> (Y_l^m is an untrustworthy orb)
<queqiao-> ⟨Damien⟩ anyone managed to reliably get an inclined l-point orbit and if so what's the trick?
<queqiao-> ⟨Damien⟩ I know that Queqiao used a lunar swing by to get into its halo orbit but if you were sending a satellite from earth to ESL1 how would you reliably get into a vertically aligned orbit?
<queqiao-> ⟨sichelgaita⟩ ⟪🇺🇦 Katniss 🇺🇦⟫ Also, how is that implemented in […] ⮪ https://en.wikipedia.org/wiki/Geopotential_model#Spherical_harmonics_representation
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ Advanced stuff 👀
<queqiao-> ⟨🇺🇦 Katniss 🇺🇦⟩ very nice
<queqiao-> ⟨sichelgaita⟩ The Principia install has somewhere a file "sol_gravity_model.cfg" that has all the coefficients for the spherical harmonics.
<queqiao-> ⟨sichelgaita⟩ FWIW the Wikipedia page has a number of errors, the real truth is at https://github.com/mockingbirdnest/Principia/blob/master/documentation/Geopotential.pdf
<paculino> Would wikipedia accept that as a source?
<queqiao-> ⟨Damien⟩ > FWIW the Wikipedia page has a number of errorsif only it had a feature where you could make edits
