00:42 <queqiao-> ⟨S​paceman Spiff⟩ How massive is that cat?

01:03 <queqiao-> ⟨S​umguy⟩ @egg how goes the bowtie development?

01:05 <queqiao-> ⟨e​gg⟩ haven’t looked at that in a while, I should

01:05 <queqiao-> ⟨S​umguy⟩ looking forward to it

01:07 <queqiao-> ⟨A​l2Me6⟩ Bowtie?

01:07 <queqiao-> ⟨A​l2Me6⟩ Is that some kind of KC thing?

01:08 <raptop> oh, different KC

01:08 <queqiao-> ⟨A​l2Me6⟩ Is that some kind of _Kerbalism Contracts thing? (edited)

07:46 <queqiao-> ⟨S​tandecco⟩ Relatively large, but not that large

07:46 <queqiao-> ⟨S​tandecco⟩ He ate bits of it

16:09 <_whitenotifier> [Principia] eggrobin synchronize pull request #3076: Test passage in the compatibility paths, add a save by Reach - https://git.io/J4Rma

17:39 <queqiao-> ⟨e​gg⟩ hm, computing the angular velocity line-of-sight/plane-of-the-sky thing sounds mildly tedious

17:39 <queqiao-> ⟨D​amien⟩ ~~mildly tedious~~

17:39 <queqiao-> ⟨D​amien⟩ developmentally interesting

17:40 <queqiao-> ⟨e​gg⟩ yeah I mean it’s always soluble in linear algebra ultimately, but I don’t know if there is a way that doesn’t involve me looking at the rotation matrix and differentiating it

17:42 <queqiao-> ⟨D​amien⟩ we've already established that anything suggested for principia is automatically scheduled to be in the next release

17:42 <queqiao-> ⟨D​amien⟩ don't fight it

20:28 <queqiao-> ⟨M​3tex⟩ Hey ! I want to try to rdv with principia, from what ppl told me here few days ago, they use the target mode of the navball, but i get this (i can't see anything). Am i doing something wrong ? If yes how to fix it, and do you have extra tips ? thanks a lot

20:28 <queqiao-> ⟨M​3tex⟩ https://cdn.discordapp.com/attachments/480397772248580098/869315175650578492/Kerbal_Space_Program_Screenshot_2021.07.26_-_22.22.46.91.png

20:29 <queqiao-> ⟨e​gg⟩ Well you can’t see much because there isn’t much to see, because you are basically there already ; but you can see your trajectory with respect to the target, you keep bobbing up and down

20:29 <queqiao-> ⟨e​gg⟩ if you hover over the yellow markers you will see the approach distances

20:30 <queqiao-> ⟨e​gg⟩ (and in that screenshot you can see that you are going 295 m/s out of plane, so I recommend slowing that down lest you slam violently into the target)

20:32 <queqiao-> ⟨M​3tex⟩ ok thanks i see the distances (pretty far because i accidentally ended in almost the same orbit as my target, i'll try to change it a little bit to catch up and see what i can do with the planner) thanks again

20:34 <queqiao-> ⟨e​gg⟩ see also https://github.com/mockingbirdnest/Principia/wiki/A-guide-to-performing-low-orbit-rendezvous

20:39 <queqiao-> ⟨M​3tex⟩ thanks ^^

20:57 <queqiao-> ⟨e​gg⟩ blarg that angular velocity really looks like it is nasty

20:59 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ That is unfortunate

21:00 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Have any of the reference frames been more difficult to do the math for that the angular velocity stuff appears to be?

21:02 <queqiao-> ⟨e​gg⟩ that question does not make much sense, since the angular velocity in question is the angular velocity of a reference frame I am trying to add, and all reference frames have such a thing

21:03 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I phrased that poorly; does this reference frame appear more difficult than the prior ones you have implemented

21:03 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I phrased that poorly; does this reference frame appear more difficult than the prior ones you have implemented? (edited)

21:03 <queqiao-> ⟨e​gg⟩ yes, otherwise I wouldn’t be complaining about it :-p

21:04 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Well, I thought maybe one had been as hard or harder in the past maybe

21:05 <queqiao-> ⟨e​gg⟩ I mean, there are only four reference frames, two of them are basically the same (the barycentric and the aligned/orbit rotate in the same way), one has constant rotation, and the remaining one doesn’t even rotate

21:06 <queqiao-> ⟨e​gg⟩ the orbit reference frame rotates reasonably nicely in that the rotation is purely determined from the dynamics, whereas here we are injecting local celestial north to avoid having the reference frame flipping upside-down whenever the apparent motion goes retrograde
