10:32 <_whitenotifier-edb> [Principia] pleroy 8015837 - Merge.

10:53 <discord-> egg. — @lpg @scimas @Stonesmile @Zeusbeer *et al.*; here is a (Windows-only) test build of Principia with the fix for the first part of #2400, *i.e.*, things being slow if you are far from 1950, the problem for which scimas’s initial states were a workaround.

10:53 <discord-> egg. — This does *not* address issues arising from long histories, it merely improves performance when you are playing in modern times with short vessel histories.

10:53 <discord-> egg. — See <https://github.com/mockingbirdnest/Principia/issues/2400#issuecomment-830861942> for details.

10:53 <discord-> egg. — Please play with it somewhat far from 1950 (in the 60s or later) and see if you encounter any issues; it involves some fairly deep changes so we would like to make sure it is safe.

10:53 <discord-> egg. — Please report any issues you encounter with it, with a journal to the extent possible.

10:53 <discord-> egg. — https://bit.ly/3w7ejWX

11:17 <discord-> Zeusbeer. — 'This does not address issues arising from long histories, it merely improves performance when you are playing in modern times with short vessel histories. ' This is exactly what I wanted

11:17 <discord-> Zeusbeer. — because I mainly sandbox

11:18 <discord-> Zeusbeer. — 'This does not address issues arising from long histories, it merely improves performance when you are playing in modern times with short vessel histories. ' This is exactly what I wanted!!! (edited)

11:18 <discord-> Zeusbeer. — Ima testa 1970 load right now

11:18 <discord-> Zeusbeer. — Ima test a 1970 load right now (edited)

11:18 <discord-> Zeusbeer. — Ima test a 1970 load in a bit (edited)

11:21 <discord-> Zeusbeer. — WOW!

11:21 <discord-> Zeusbeer. — Is it possible that timewarping full speed also has performance improvements?

11:21 <discord-> Zeusbeer. — I'm at 1960 in no time, with no lag

11:21 <discord-> egg. — I don’t think it would affect timewarp speed (that is primarily limited by there being vessels)

11:22 <discord-> Zeusbeer. — hmm, with a blank save it would still lag at full speed

11:22 <discord-> Zeusbeer. — right now it doesn't and it's super smooth

11:26 <discord-> Zeusbeer. — Transition time is 35.61 seconds from kerbalX to tracking station in a blank save

11:26 <discord-> Zeusbeer. — Transition time is 35.61 seconds from kerbalX to tracking station in a blank save in 1976 (edited)

11:26 <discord-> Zeusbeer. — -30

11:26 <discord-> Zeusbeer. — Transition time is 35.61 seconds from kerbalX to tracking station in a blank save in 1976-5-30 (edited)

11:26 <discord-> Zeusbeer. — but I need to compare to the old build

11:27 <discord-> egg. — hm, I am getting something more like 10 s, and I am in 2002

11:27 <discord-> Zeusbeer. — hm

11:28 <discord-> Zeusbeer. — I was defenitly testing the test build, on an NVME drive too

11:28 <discord-> Zeusbeer. — on 1.11.2 too

11:29 <discord-> egg. — what is your max history length setting?

11:29 <discord-> egg. — (but that shouldn’t matter, because reconstructing the desired history is not blocking now…)

11:29 <discord-> Zeusbeer. — oh that might have been quite long

11:29 <discord-> egg. — oh

11:29 <discord-> egg. — oh wait

11:29 <discord-> egg. — we screwed up the releasing

11:29 <discord-> egg. — This is master, not Grassmannian

11:29 <discord-> Zeusbeer. — yeah on Grassman the timewarping is defenitly slower

11:30 <discord-> Zeusbeer. — ouch

11:30 <discord-> egg. — OK, so congratulations, you have found a completely unrelated performance improvement

11:30 <discord-> egg. — rnlahaye apparently did a stellar job at optimization

11:30 <discord-> Zeusbeer. — no problem 🙃

11:31 <discord-> Zeusbeer. — can I have a banana now

11:31 <discord-> Zeusbeer. — 🎊

11:32 <discord-> Zeusbeer. — yeah timewarping to 1976 is painfull with the old release

11:32 <discord-> Zeusbeer. — like at least 2x as low

11:32 <discord-> Zeusbeer. — like at least 2x as slow (edited)

11:33 <discord-> Zeusbeer. — time to benchmark kerbalX -> tracking station

11:34 <discord-> egg. — @Zeusbeer do you have asteroids on?

11:35 <discord-> Zeusbeer. — YES

11:35 <discord-> Zeusbeer. — yes (edited)

11:35 <discord-> Zeusbeer. — 34.98 seconds on Grassmann

11:35 <discord-> Zeusbeer. — also mind the human reaction time error

11:39 <discord-> Zeusbeer. — I will do another test on a blank save without asteroids

11:39 <discord-> Zeusbeer. — do I just turn tracking off?

11:39 <discord-> Zeusbeer. — Like this?

11:45 <discord-> Zeusbeer. — no history, no asteroids, still 35 seconds, are you sure 'TEST2985-0' is the correct version?

11:46 <discord-> egg. — No, as I said, it is not

11:46 <_whitenotifier-edb> [Principia] pleroy 6aa872c - Merge remote-tracking branch 'mockingbirdnest/master' into Grassmannian

11:46 <discord-> egg. — We screwed up

11:49 <discord-> egg. — Also no, this is not how you turn asteroids off, they are still being simulated, just not displayed; you have to remove the potatoroids entirely, see the FAQ.

11:51 <discord-> egg. — @Zeusbeer see https://discord.com/channels/319857228905447436/480397772248580098/843087791525068810, we developed those changes in a separate branch and built the wrong one. Currently building the correct one.

11:51 <discord-> Zeusbeer. — 👍

11:51 <discord-> Zeusbeer. — I guess also removing 'potatoComet' might help?

11:51 <discord-> egg. — I suppose; those are newer than that entry in the FAQ.

11:52 Hypergolic_Skunk has quit [Quit: Connection closed for inactivity]

11:54 <discord-> egg. — @Zeusbeer to clarify, because there are a lot of things being discussed here:

11:54 <discord-> egg. — — the faster warp you are seeing is probably specifically something about the vessels, so the potatoroids, from a change by rnlahaye ; without the potatoroids I would expect 2985 and Grassmann to have the same speed.

11:54 <discord-> egg. — — the thing we are interested in (for the upcoming 2986 build) is the faster transition times (this is about that part of 2400).

11:58 <discord-> egg. — @Zeusbeer New build, this time with the correct branch https://bit.ly/33KE2Zb

11:59 <discord-> Zeusbeer. — 🙂

11:59 <discord-> Zeusbeer. — if this works, this will be the most exciting update in a long time

12:04 <discord-> Zeusbeer. — WOW

12:04 <discord-> Zeusbeer. — 3.92 seconds from kerbalX to tracking station

12:05 <discord-> Zeusbeer. — in 1976-5-30

12:05 <discord-> egg. — Now we are talking :-)

12:05 <discord-> Zeusbeer. — a few more voyager attempts incoming in the next few months

12:05 <discord-> Zeusbeer. — I'll let it go towards 2050 or something in a bit, see how things go

12:05 <discord-> egg. — If you set a long history length, you can see what is happening under the hood: you will see the past trajectories of the planets increase towards the past in steps of 6 months

12:06 <discord-> egg. — i.e., we load first with no history, and then we recompute the past as needed, without blocking

12:06 <discord-> egg. — *i.e.*, we load first with no history, and then we recompute the past as needed, without blocking (edited)

12:06 <discord-> Zeusbeer. — I can see that yes

12:07 <discord-> Zeusbeer. — the performance is amazing

12:12 <discord-> Zeusbeer. — 4.4 seconds in 2021

12:13 <discord-> Zeusbeer. — 4.4 seconds in 2021-7 (edited)

12:21 <discord-> Zeusbeer. — 6.54 seconds for 2100

12:21 <discord-> Zeusbeer. — but I guess that would be a very rare test case

12:21 <discord-> Zeusbeer. — the planet alignment looks a lot different here 😂

12:22 <discord-> Zeusbeer. — https://cdn.discordapp.com/attachments/480397772248580098/843100989301325843/unknown.png

12:24 <discord-> Zeusbeer. — now it's finally mentally feasable to do a hohman transfer to Pluto!

12:28 <discord-> Zeusbeer. — now the next step is to add support for Haumea 😂

12:29 <discord-> Zeusbeer. — the ultimate egg

12:49 egg|cell|egg has joined #principia

12:51 <discord-> Kobymaru. — 😮

12:52 <discord-> Kobymaru. — I'm in 1972 and my scene changes went down from 80s to 15-20s

12:52 egg|cell|egg has quit [Ping timeout: 204 seconds]

12:53 <discord-> Kobymaru. — But that's with my full RP-1 install. It feels like the "freeze" after you click the button to change scene is now down to a few seconds

12:53 <_whitenotifier-edb> [Principia] Success. #1471 succeeded - https://dev.azure.com/mockingbirdnest/445d7b9d-0318-42e3-857f-b69d40b1ed1b/_build/results?buildId=1471

12:53 <discord-> egg. — yeah I have 10 s in 2002 with RSS/RO (but no RP)

12:54 <discord-> Kobymaru. — However, something funky is happening with the orientation and rotation

12:54 <discord-> siimav. — *Pedestrian programming* isn't so bad after all? 😉

12:54 <discord-> Kobymaru. — seems like it

12:55 <discord-> egg. — we never said it wasn’t effective, but it is tedious

12:55 <discord-> egg. — If there are two equally effective solutions to a problem, one is obvious, and the other a research problem, the latter must be preferred

12:55 <discord-> Kobymaru. — When I loaded it up, the orientation was wrong and rotation was stopped. I aligned myself again and induced a spin, went to tracking station. Went back to the vessel, for a brief moment the orientation was correct only to flip into the wrong direction. Rotation was stopped again

12:56 <discord-> Kobymaru. — rotation at time warp still seems to work

12:56 <discord-> egg. — That is weird; it sounds like some other mod is interfering with your orientation

12:57 <discord-> Kobymaru. — Well I definitely didn't install PersistentRotation. It worked before I changed to the test buld

12:57 <discord-> Kobymaru. — Well I definitely didn't install PersistentRotation. It worked before I changed to the test build (edited)

12:57 <discord-> egg. — hmm.

12:58 <discord-> egg. — @Kobymaru is the history of the relevant vessels still there?

12:58 <_whitenotifier-edb> [Principia] Success. #1470 succeeded - https://dev.azure.com/mockingbirdnest/445d7b9d-0318-42e3-857f-b69d40b1ed1b/_build/results?buildId=1470

12:59 <discord-> Kobymaru. — Nope, history is goe

12:59 <discord-> Kobymaru. — Nope, history is gone (edited)

12:59 <discord-> egg. — Aha!

13:00 <discord-> Kobymaru. — Max history length set to zero

13:00 <discord-> Kobymaru. — works for the celestials though

13:00 <discord-> Kobymaru. — As far as I can tell, history for ALL vessels has disappeared

13:01 <discord-> egg. — I think I know the culprit then, https://github.com/mockingbirdnest/Principia/pull/2983 must be a bit too eager

13:02 <discord-> Kobymaru. — what on earth are "unfaithful" parts? 😅

13:02 <discord-> Zeusbeer. — yes

13:03 <discord-> Zeusbeer. — ion engines?

13:03 <discord-> egg. — no rigidbody or NaN degrees of freedom

13:03 <discord-> Zeusbeer. — and in pedestrian programming language

13:03 <discord-> egg. — we also have a concept of truthful parts

13:03 <discord-> Kobymaru. — interesting

13:04 <discord-> Kobymaru. — I increased max history length to 2 days before switching scenes, orientation still flips and rotation stops when switching to a vessel

13:04 <discord-> egg. — max history length is a display setting

13:04 <discord-> Kobymaru. — is the "max history length" still just for show?

13:04 <discord-> egg. — yes

13:04 <discord-> Kobymaru. — ok

13:04 <discord-> egg. — my question was whether the history had been cut

13:04 <discord-> Zeusbeer. — green noodles 😋

13:05 <discord-> egg. — When you say « history is gone », does that mean that there is no history regardless of the choice of max history length for those vessels ?

13:05 <discord-> egg. — or does that mean you set the « for show » setting to 0

13:06 <discord-> Kobymaru. — It means that when I increase the displayed history, for celestials, the trajectory gets elongated back in time. but for vessels it is not. No green noodles for vessels anymore.

13:07 <discord-> Kobymaru. — except the part since the scene change, that's shown

13:07 <discord-> egg. — OK; so it does sound like the unfaithful check is messing with us

13:07 <discord-> Zeusbeer. — when my final exams are finished I'm gonna recreate New Horizons

13:07 <discord-> Zeusbeer. — 🙂

13:11 <discord-> egg. — oh wow, this is really bad

13:12 <discord-> egg. — @Zeusbeer I know why warp with asteroids was fast: all vessels are unmanageable

13:12 <discord-> egg. — so your asteroids (which slow high warp a lot) were ignored)

13:12 <discord-> egg. — so your asteroids (which slow high warp a lot) were ignored (edited)

13:12 <discord-> Zeusbeer. — so this version is not usable?

13:14 <discord-> egg. — Not really (but the fast transition is a real thing, it’s just that an unrelated bugfix broke having vessels other than the active one)

13:15 <discord-> lpg. — motorcycle programming now?

14:01 <discord-> egg. — yeah, since you have a bunch of vessels I suspect that is their histories making the save big (the other part of 2400). still, 45 s is a nice improvement

14:53 <discord-> Stonesmile. — Tried the latest build; my 1965 save loading a sat went from 44 sec down to 32 sec; quite a lot of vessel data to load

16:55 <discord-> Zeusbeer. — or more importantly: Giacobini-Zinner

17:35 <discord-> scimas. — If it's added like a planet then the same way the initial RSS state is provided with Principia, the same way I made 5 year initial states - by querying the JPL Horizons data.

17:42 <discord-> Zeusbeer. — hmm now the next question is, how to get the Cartesian vectors of Arrokoth from 1951?

17:50 <discord-> Zeusbeer. — You'd have to calculate this backwards

19:33 <discord-> Zeusbeer. — mhm I swear I put everything in correctly, it's still so inclined

20:08 <discord-> Zeusbeer. — well

20:08 <discord-> Butcher. — Ah the type random numbers and see what falls out approach.

20:09 <discord-> Zeusbeer. — I did check if they aligned with what was already in the file for different planets like Vesta

20:10 <discord-> egg. — If you click on change you get more detailed settings

20:10 <discord-> egg. — If your inclination is wrong, your choice of reference plane is probably wrong

20:12 <discord-> Zeusbeer. — I'll try @sun

20:12 <discord-> egg. — In fact it almost certainly is wrong given the summary in Table Settings

20:12 <discord-> egg. — Stop trying things

20:12 <discord-> egg. — Understand

20:12 <discord-> egg. — The table settings are wrong

20:12 <discord-> egg. — Read the options

20:13 <discord-> egg. — And compare that to the .f in the repo

20:13 <discord-> egg. — @sun would just be even more wrong

20:25 <discord-> Zeusbeer. — Thank you Egg

20:26 <discord-> egg. — SSB (@0) is correct fwiw

21:04 <discord-> Zeusbeer. — I'm not sure if you can use it for multiple flyby interplanetary transfers though

21:04 <discord-> Cristi. — We need to have an option in principia to change the colour of orbits :)

21:04 <discord-> Al2Me6. — It exists.

21:05 <discord-> Zeusbeer. — You can somewhere in the config

21:05 <discord-> Al2Me6. — https://github.com/mockingbirdnest/Principia/wiki/Principia-configuration-files#the-principia_draw_styles-configuration

21:05 <discord-> Zeusbeer. — red looks kinda cool tbh

21:06 <discord-> Zeusbeer. — or even cooler would be an option where the noodles would be colormapped based on the difference in altitude from the reference body

21:06 <discord-> egg. — but then it is no longer the Great Purple (or more accurately fuchsia) noodle

21:06 <discord-> Zeusbeer. — but my hotpink noodle 🙃

21:06 <discord-> Paculino (ŝi/ri/she/they). — If you're color blind enough, you can't tell the difference

21:09 <discord-> Zeusbeer. — (hotpink is actually a bad color, I prefer neon pink)

21:09 <discord-> Zeusbeer. — at least the hotpink from matplotlib

21:10 <discord-> Cristi. — egg, your fix will be implemented in the new moon? I'm in '70s and it started to get very slow.

21:10 <discord-> Zeusbeer. — I think he wanted to do one after the new moon

21:11 <discord-> Zeusbeer. — maybe we can get a half moon update 🙃

21:11 <discord-> Cristi. — Time to do something else then :)

21:11 <discord-> egg. — There is no such thing as a full moon release

21:11 <discord-> egg. — Unless someone finds a catastrophic bug, this should be in Gröbner

21:12 <discord-> Zeusbeer. — Is Gröbner after Grassmann?

21:12 <discord-> egg. — Is O after A?

21:12 <discord-> Cristi. — it's a trap, do not respond to that

21:13 <discord-> Zeusbeer. — Yes but there might be an inbetween letter

21:13 <discord-> Paculino (ŝi/ri/she/they). — Some something transliteration/diacritical marks in alphabetical order too

21:13 <discord-> egg. — well, yes, what is the current release

21:13 <discord-> Zeusbeer. — B,C,D,E,F,G,H,I,J,K,L,M,N

21:14 <discord-> Zeusbeer. — B,C,D,E,F,G,H,I,J,K,L,M,N, where G would obviously dissapear (edited)

21:14 <discord-> egg. — @Zeusbeer the current release is not Grassmann

21:14 <discord-> Paculino (ŝi/ri/she/they). — Grb etc would be hard to say, so just Gre and Gri should one consider

21:15 <discord-> egg. — Does anyone here actually know what the current version is

21:15 <discord-> Zeusbeer. — Green

21:15 <discord-> Zeusbeer. — I just found it 😂

21:15 <discord-> Cristi. — Yes

21:15 <discord-> Cristi. — Green with purple noodles

21:17 <discord-> Zeusbeer. — I'm getting bullied today 😂

21:21 <discord-> Paculino (ŝi/ri/she/they). — Cristi seems to have known

21:26 <discord-> Zeusbeer. — Timewarping to 2100-05 really gets to you
