00:01 <_whitenotifier-653e> [Principia] eggrobin closed pull request #3300: Fix tolerances and a warning with Clang 12 - https://github.com/mockingbirdnest/Principia/pull/3300

01:59 <queqiao-> ⟨theeo⟩ i don’t really understand steps and tolerance, what does changing them do?

01:59 <queqiao-> ⟨theeo⟩ is it just calculation accuracy?

02:01 <queqiao-> ⟨Al2Me6⟩ Tolerance - what it says on the tin. How accurate the prediction is.

02:01 <queqiao-> Steps - more = longer prediction at the same tolerance.

02:06 <queqiao-> ⟨theeo⟩ okay, thank you

02:22 <queqiao-> ⟨n9gaming⟩ _can you though, and just not tell anyone else_ >.>

02:22 <queqiao-> ⟨Al2Me6⟩ For what, cleaning up old trajectories? That's getting fixed next 🌚

02:23 <queqiao-> ⟨lpg⟩ my main use for Hack Gravity is using hyperedit

02:23 <queqiao-> ⟨n9gaming⟩ ^ that's good to know! But moreso for launches, camera tools` static camera doesn't stay put unless hack gravity is toggled, let alone the few extra frames for launches 😛

03:04 <queqiao-> ⟨egg⟩ ⟪n9gaming⟫ ^ that's good to know! But moreso for […] ⮪ I am pretty sure hacking gravity is not how we should fix the camera

03:12 <raptop> /* Dirty hack, but should add enough indexes that we can finally properly do the tensors and fix Mercury's orbit */

03:52 <queqiao-> ⟨Kerbinator(no guarantee suggest)⟩ ⟪Al2Me6⟫ For what, cleaning up old trajectories? […] ⮪ Is it the reason of lag described by Reach, even reverted vessels can make game laggier?

10:08 <queqiao-> ⟨RurouniDonut⟩ 👀👀 I see lots of new stuff going on. Is this next update gonna be a performance king?

10:09 <queqiao-> ⟨Quadrupole⟩ It will solve the problem of save being too large and thus reduce scene change time

10:09 <queqiao-> ⟨RurouniDonut⟩ Thats awesome

10:10 <queqiao-> ⟨RurouniDonut⟩ Principia devs = best devs

10:38 <queqiao-> ⟨theeo⟩ ⟪Al2Me6⟫ Tolerance - what it says on the tin. […] ⮪ one more thing about that, does turning the tolerance up or down increase the accuracy? i’m assuming down?

10:39 <queqiao-> ⟨von Kerman⟩ Higher tolerance = Lower accuracy

10:40 <queqiao-> ⟨theeo⟩ alright, thank you

11:29 <queqiao-> ⟨Kobymaru⟩ so will the history be automatically converted to the new format or do we have to manually delete it with hack gravity?

11:31 <queqiao-> ⟨von Kerman⟩ This seems to suggest that hacking will not be required https://discord.com/channels/319857228905447436/480397772248580098/934249982448533595

11:32 <queqiao-> ⟨Kobymaru⟩ that would be awesome. I think the plan a few weeks/months ago was to leave existing trajectories untouched

12:23 <queqiao-> ⟨sichelgaita⟩ Existing trajectories won't be touched. There is not enough information there to compress them. Only new trajectories will benefit from the new, compact representation.

12:37 <queqiao-> ⟨von Kerman⟩ What makes a trajectory new? If there an existing vessel when I switch to the new version, will its future trajectory be compressed? Or only newly launched vessels benefit from the compression?

12:41 <queqiao-> ⟨von Kerman⟩ +is

12:41 <queqiao-> ⟨von Kerman⟩ +will

12:43 <queqiao-> ⟨egg⟩ ⟪von Kerman⟫ What makes a trajectory new? If there […] ⮪ > If there is an existing vessel when I switch to the new version, will its future trajectory be compressed?yes.

20:56 <queqiao-> ⟨egg⟩ ⟪_whitenotifier-653e⟫ [Principia] rnlahaye opened pull […] ⮪ rnlahaye I see we have come to the same conclusion, sichelgaita had told me to do this :D

20:57 <queqiao-> ⟨rnlahaye⟩ lol

20:58 <queqiao-> ⟨egg⟩ (though I think my conclusion was that that swap was pointless, accessing something moved-from is evil anyway)
