02:25 <rsparkyc> so i remember hearing that it's a feature that you can't target celestials. What's the best way to get my relative inclination to one then?

12:37 <rsparkyc> um, how is this even possible?

20:26 <UmbralRaptor> o_o

20:26 <UmbralRaptor> pastebin?

20:27 <rsparkyc> you guys and your pastebin…

20:27 <rsparkyc> what's the ethical limit to number of lines you should paste here?

20:28 <UmbralRaptor> ambiguous, I'd use 4 as a guess.

20:28 <rsparkyc> ok

20:28 <rsparkyc> i'll paste in batches of 4 then :)

20:28 <UmbralRaptor> aaaaaa

20:28 <rsparkyc> i bet this is the issue

20:28 <rsparkyc> F0501 16:25:20.248947 2704909248 continuous_trajectory_body.hpp:215] Check failed: s.t_max() < checkpoint.t_max_ (-1.32383520000000000e+09 s vs. -1.32384000000000000e+09 s)

20:28 <rsparkyc> (there, 1 line)

20:29 <rsparkyc> got that from stderr.log

20:29 <rsparkyc> egg, any ideas?

20:30 <rsparkyc> ooo, termbin FTW

20:30 <rsparkyc> http://termbin.com/m5vx

20:30 <egg> rsparkyc: make an issue, send the INFO log that ends with this FATAL log

20:31 <rsparkyc> will do

20:31 <egg> it has to be the INFO log, otherwise we can't decode the stacktrace, and it has to be the one with that FATAL log obviously :-p

20:32 <rsparkyc> the Player.log?

20:32 <egg> ...

20:32 <egg> our logs

20:32 <rsparkyc> i'll find it

20:32 <egg> we have our logs, and we describe how to find them right at the beginning of the FAQ

20:32 <egg> which you have read

20:34 <rsparkyc> glog dir

20:36 <egg> ja genau

20:39 <rsparkyc> of course, i wipe out that directory, try to reproduce it, and it doesn't break...

20:39 <egg> why the fuck do you wipe that directory

20:39 <egg> it's the bloody logs

20:40 <egg> you're not supposed to wipe them, you're supposed to send them to me and do nothing else!

20:40 <rsparkyc> because 1) it was full of old crap, and 2) i like to make sure i'm sending you the right stuff so you're not waisting your time

20:40 <rsparkyc> and 3) it happened twice in a row, so i figured it was repeatable

20:41 <egg> never trust that something is repeatable, 1. is fine, that old crap can be useful, 2. that's why I ask you to look for the one that ends with that FATAL failure

20:41 <egg> (which you can find because it's *the exact same line*)

20:43 <rsparkyc> well, you're in luck, because i catted the file i think was it

20:44 <rsparkyc> http://termbin.com/cwrx

20:44 <rsparkyc> i'll make an issue with that

20:44 <egg> yup that's the right FATAL failure

20:44 <egg> oooooh but it's OS X

20:44 <rsparkyc> see, useless :)

20:44 <egg> I can't decode non windows traces, you'll have to forward that to lamont

20:45 <egg> keep that log though, it's interesting

20:46 <rsparkyc> !tell lamont egg thought you might like this one: http://termbin.com/cwrx

20:46 <Qboid> rsparkyc: I'll redirect this as soon as they are around.

20:47 <egg> rsparkyc: forwarded the FATAL log to phl, who agrees that it's going to be hard

20:48 <rsparkyc> hard to fix? hard to diagnose?

20:49 <egg> to diagnose

20:49 <rsparkyc> a little background: on a RealismOverhaul install, about 8 years in

20:49 <rsparkyc> that happened going into the tracking station

21:02 <lamont> hmmm

21:02 <Qboid> lamont: rsparkyc left a message for you in #principia [01.05.2017 20:46:10]: "egg thought you might like this one: http://termbin.com/cwrx"

21:03 <lamont> that looks like its just floating point differences

21:03 <lamont> there’s that pile of failing tests i ignored because it was tiny deltas off by even tinier deltas

21:03 <egg> it most certainly doesn't look like that, lamont

21:04 <lamont> F0501 16:25:20.248947 2704909248 continuous_trajectory_body.hpp:215] Check failed: s.t_max() < checkpoint.t_max_ (-1.32383520000000000e+09 s vs. -1.32384000000000000e+09 s)

21:04 <lamont> ^ that?

21:04 <egg> that's a huge difference, nowhere near the limit of precision

21:04 <lamont> oh ‘k

21:04 <lamont> oh e+09

21:04 <egg> if it's FP roundoff stuff, it's in the last digits

21:04 <lamont> welp

21:04 <egg> here it's only 6 digits in

21:05 <egg> there's a logic failure here of sorts, but good flippin' luck with that :-\

21:05 <rsparkyc> 1/1000 %?

21:05 <rsparkyc> where's the mantissa on that number?

21:05 <rsparkyc> and is it double precision?

21:05 <lamont> some sort of integration where a round off error of some sort gets magnitifed by orders of magnitude?

21:07 <egg> no

21:07 <egg> ;rpn -1.32383520000000000e+09 -1.32384000000000000e+09 -

21:07 <kmath> egg: 4800.0

21:08 <egg> that's off by a whole checkpoint probably

21:11 <egg> rsparkyc: this is a save you created with Cartan?

21:11 <rsparkyc> yeah

21:12 <egg> so the default timestep of the ephemeris is 10 min, which is 600 s

21:12 <rsparkyc> well, i gotta run

21:12 <egg> ;rpn 4800 600 /

21:12 <kmath> egg: 8.0

21:12 <egg> yeah, 8 points, that's a whole polynomial

21:12 <rsparkyc> i'll prob be on later tonight, feel free to leave me a message me if you want me to try anything

21:13 <egg> well try to reproduce it

21:13 <rsparkyc> not that I expect there to be anything for me to try :)

21:13 <rsparkyc> yeah, i will

21:13 <egg> if you can do so deterministically, turn on journalling
