13:37 <queqiao-> ⟨Z​eusbeer⟩ well crap

13:37 <queqiao-> ⟨Z​eusbeer⟩ I updated to gröbner, didn't realize it didn't work, and now my rp-1 save broke

13:37 <queqiao-> ⟨Z​eusbeer⟩ (because I timewarped with conics)

13:40 <queqiao-> ⟨Z​eusbeer⟩ no backups 😅

13:43 <queqiao-> ⟨Z​eusbeer⟩ weird, gröbner is not working at all

13:44 <queqiao-> ⟨Z​eusbeer⟩ This is how it's supposed to look right?

13:44 <queqiao-> ⟨Z​eusbeer⟩ https://cdn.discordapp.com/attachments/480397772248580098/853993230555152384/unknown.png

13:44 <queqiao-> ⟨Z​eusbeer⟩ downloaded it straight from releases

13:44 <queqiao-> ⟨s​iimav⟩ Is that your GameData? 😱

13:44 <queqiao-> ⟨Z​eusbeer⟩ part of

13:45 <queqiao-> ⟨s​iimav⟩ That's very wrong then

13:45 <queqiao-> ⟨s​iimav⟩ Folder name should be Principia and there shouldn't be another Principia folder inside it

13:45 <queqiao-> ⟨Z​eusbeer⟩ there isn't

13:46 <queqiao-> ⟨Z​eusbeer⟩ it was called principia on the test version

13:46 <queqiao-> ⟨Z​eusbeer⟩ I guess I rename it, I don't like unzipping things

13:54 <queqiao-> ⟨Z​eusbeer⟩ I guess I'll put it in a folder called principia (edited)

14:13 <queqiao-> ⟨e​gg⟩ WTF

14:54 <queqiao-> ⟨e​gg⟩ @Zeusbeer I suggest reading https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions#installing-principia again

14:55 <queqiao-> ⟨e​gg⟩ and not downloading a random thing that looks nothing like what Principia looked like last time you installed it

14:55 <queqiao-> ⟨e​gg⟩ because chances are, that’s not the right thing

14:56 <queqiao-> ⟨S​tonesmile⟩ Well there's your porblem; never get release - download from readMe

14:57 <queqiao-> ⟨A​l2Me6⟩ (Release contains the source code only, that ain't gonna run)

15:04 <queqiao-> ⟨Z​eusbeer⟩ Lmao

15:44 <queqiao-> ⟨D​amien⟩ @Zeusbeer's lady friend: unzip my dress pls

15:44 <queqiao-> ⟨D​amien⟩ @Zeusbeer: no sorry best I can do is give you a new name

15:58 <raptop> ...is getting the tar out of it sufficient?

16:29 <queqiao-> ⟨S​tandecco⟩ he renamed the entire file bit by bit until he had principia working

16:31 <raptop> O_o O_O o_O

16:34 <queqiao-> ⟨Z​eusbeer⟩ I'm retarded

16:34 <queqiao-> ⟨Z​eusbeer⟩ Stop bullying please

16:35 <queqiao-> ⟨Z​eusbeer⟩ Even egg saying WTF 🤣

16:37 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ this is why you make backups

17:10 <queqiao-> ⟨e​gg⟩ I wonder how big a DLL that just pops up a « this is not how you install the mod, do not load a save » dialog would be, checking in such a thing into the tree would be a way to handle this disturbingly common failure to install

17:20 <queqiao-> ⟨S​tonesmile⟩ What is the reason for hosting the download on G-drive instead of GH?

17:47 <raptop> something about trackikng # of downloads

17:51 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I wonder if anyone actually tried that

18:08 <queqiao-> ⟨e​gg⟩ yeah specifically we use bit.ly analytics to count downloads

18:10 <queqiao-> ⟨e​gg⟩ (those analytics are also how we found out we had a lot of users in CN, which is why we then added the 腾讯微云 download)

18:10 <queqiao-> ⟨S​tonesmile⟩ Gotcha!

18:17 <queqiao-> ⟨A​shnoom⟩ OnLoad(){ System.Exit("moron");}

18:17 <queqiao-> ⟨A​shnoom⟩

18:17 <queqiao-> ⟨A​shnoom⟩ No?

18:18 <queqiao-> ⟨A​shnoom⟩ It whatever a proper C# impl would be

18:18 <queqiao-> ⟨A​shnoom⟩ Or whatever a proper C# impl would be (edited)

18:19 <queqiao-> ⟨e​gg⟩ yeah (or even a UnityEngine.GUILayout modal window to actually make the error visible) it’s more the size of the resulting DLL that I wonder about (I don’t like checking in binaries, let alone large ones)

18:20 <queqiao-> ⟨s​iimav⟩ <10kB

18:25 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ What if you just put the current binaries main folder into another folder saying "Always Install Principia from ReadMe"

18:25 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ What if you just put the current binaries main folder into another folder named "Always Install Principia from ReadMe" (edited)

18:25 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ What if you just put the current binaries main folder into another folder named "Always Install Principia from ReadMe"? (edited)

18:36 <queqiao-> ⟨e​gg⟩ ??? the issue is that people are not downloading the binaries, they are downloading the source tree

18:38 <raptop> git pull && make clean

18:38 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Oh

18:38 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Well, I meant put all of the folders of incorrect downloads for installation into another folder that is named something telling to install from ReadMe

18:40 <queqiao-> ⟨e​gg⟩ The incorrect downloads are literally downloading the source tree, I am not going to start messing with the structure of that (which is the thing we work with when developping Principia, and the specifics of which all the tooling depends on) to deal with people not reading the docs

18:41 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Oh, I was unaware of the difficulty that putting it all under a new folder would add

18:42 <queqiao-> ⟨e​gg⟩ it would also likely make revision history illegible, etc.

18:43 <queqiao-> ⟨e​gg⟩ and even then, people would not see that directory; the directory they download is named after repo and the release name

18:44 <raptop> Obviously Principia should be ported to a language like Perl or Python, so you can directly run the source tree

18:44 <queqiao-> ⟨e​gg⟩ So unless you are suggesting we rename the mod to YouAreInstallingPrincipiaWrong rather than Principia I don’t think it would help, people would still end up downloading a Principia-date-SomeMathematician directory

18:45 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Yeah... horrible idea I had

18:47 <bees> python might work

18:48 <queqiao-> ⟨A​shnoom⟩ With what supercomputer?

18:48 <queqiao-> ⟨A​shnoom⟩ Also. No threading. Only subprocessing

18:49 <queqiao-> ⟨A​shnoom⟩ Something something GIL. United you go for ItonPython

18:49 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ It's python, there is a plugin to fix that already

18:49 <queqiao-> ⟨A​shnoom⟩ Something something GIL. Unless you go for ItonPython (edited)

18:50 <queqiao-> ⟨A​shnoom⟩ There is a plug-in that avoids the GIL? What sorcery is this?

18:50 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ <https://github.com/N-BodyPhysicsSimulator>

18:50 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Stephen Meijer, the more northern egg using python

18:51 <raptop> ...supercomputer Principia should be written in FORTRAN

18:51 <queqiao-> ⟨A​shnoom⟩ COBOL

18:51 <queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Make it out of minecraft redstone logic gates, or Conway's game of life /s

18:52 <raptop> Ah, yes, N-glider gravity

19:00 <bees> also multiprocessing exists for python

19:01 <bees> ...with all usual !!FUN!! stuff

19:03 <bees> also something like numpy just ignores GIL

20:30 <queqiao-> ⟨A​shnoom⟩ True! But multithreading != Multiprocessing. Both having their outfits and cons

20:30 <queqiao-> ⟨A​shnoom⟩ True! But multithreading != Multiprocessing. Both having their pros and cons (edited)

21:02 <queqiao-> ⟨s​ichelgaita⟩ Windows "Previous Versions" might help you, maybe.

21:17 <queqiao-> ⟨e​gg⟩ @Butcher There is someone called Sesshaku on the fora who appears to have difficulty going to the Moon from Cape Canaveral, you might want to advertise your fancy script

21:19 <queqiao-> ⟨B​utcher⟩ Then I have to support it. 😐

21:19 <queqiao-> ⟨B​utcher⟩ People like their missions complicated anyway.

21:20 <queqiao-> ⟨B​utcher⟩ *He says having just built a sky crane*

21:59 <queqiao-> ⟨l​amont⟩ is there any easy way to pull state vectors and masses out of JPL ephemerides?

22:00 <queqiao-> ⟨l​amont⟩ snapshot at a current date, with bulk quantities of bodies

22:18 <queqiao-> ⟨e​gg⟩ sort of

22:18 <queqiao-> ⟨e​gg⟩ it involves sending a mail with the query in the correct format (otherwise you get an error message back), and getting back one mail per body

22:19 <queqiao-> ⟨e​gg⟩ (then parsing the vectors out of those mails but the tables are easily parsed with awk or something like that)

22:20 <queqiao-> ⟨e​gg⟩ the contents of the email should look like https://github.com/mockingbirdnest/Principia/blob/master/astronomy/query.f

22:20 <queqiao-> ⟨e​gg⟩ (the ! lines are comments)

22:21 <queqiao-> ⟨e​gg⟩ (and those comments are very dated anyway)

22:54 <queqiao-> ⟨l​amont⟩ oh cool

22:54 <queqiao-> ⟨l​amont⟩ i guess i'll see if i can blow up my e-mail then

23:25 <queqiao-> ⟨l​amont⟩ @egg so it looks like a lot of the small bodies have GM, but i guess all the major ones do not?

23:26 <queqiao-> ⟨e​gg⟩ yeah we source our masses (and geopotentials etc.) from elsewhere

23:26 <queqiao-> ⟨e​gg⟩ that is constant though so you only need to maintain one of those per body, not one per body and initial time

23:27 <queqiao-> ⟨l​amont⟩ well looks like i can find that off the telnet interface which should be good enough?

23:27 <queqiao-> ⟨e​gg⟩ that works too

23:27 <queqiao-> ⟨e​gg⟩ in case you want our fancy gravity models (with sources) see https://github.com/mockingbirdnest/Principia/blob/master/astronomy/sol_gravity_model.proto.txt

23:28 <queqiao-> ⟨e​gg⟩ yikes, this does not use proper bibliography keys

23:28 <queqiao-> ⟨l​amont⟩ ah cool

23:28 <queqiao-> ⟨l​amont⟩ so currently i just have an RK4 O(n^2) nbody integrator written in go (my first go project)

23:28 <queqiao-> ⟨l​amont⟩ i will probably need to do a bit of work before i quite get to that model...

23:29 <queqiao-> ⟨e​gg⟩ (nowadays all our references look like [New87] and correspond to entries in https://github.com/mockingbirdnest/Principia/blob/master/documentation/bibliography.pdf)

23:30 <queqiao-> ⟨e​gg⟩ (note that [New87] is neither the same New— nor the same 80s as [New89])
