egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…
<queqiao-> ⟨night_beast⟩ Is like 2 3/4 years the most you can "plan" out? Tying to make sure I get this right
<queqiao-> ⟨test_account⟩ Its amazing that such a long plan if such a curved and complicated trajectory is even possible
<queqiao-> ⟨test_account⟩ * of
<queqiao-> ⟨test_account⟩ However, its probably completely worthless with a precision of 1jm
<queqiao-> ⟨test_account⟩ * 1km
<queqiao-> ⟨night_beast⟩ oh no doubt... the calculations that have to go into almost 3 years of planning 😮 .
<queqiao-> Why do you say a precision of 1km is "worthless"? I'm not trying to land on a landing pad, I'm trying to orbit L5
<queqiao-> ⟨test_account⟩ The error is too high, the trajectory is likely incorrect
<queqiao-> ⟨test_account⟩ When i tried increasing tolerance to 1km for a mission to saturn, it broke down bad enough to be unusable
<queqiao-> ⟨test_account⟩ Here even very little errors can totally change its shape
<queqiao-> ⟨night_beast⟩ I've got to do some stage separation events anyway, so it'll get me close enough and I'll just fine-tune from there.
<queqiao-> ⟨sichelgaita⟩ Funny, I thought that I had fixed the "error 4" message?!
<queqiao-> ⟨egg⟩ night_beast, are you using the latest version?
<queqiao-> ⟨Al₂Me₆⟩ ⟪egg⟫ night_beast (@_discord_32508018845299507[…] ⮪ (They evidently do have equipotentials...)
<queqiao-> ⟨egg⟩ oh, right.
<queqiao-> ⟨night_beast⟩ the one that was available when RP-1 V2 launched... let me see
<queqiao-> ⟨egg⟩ ⟪night_beast⟫ the one that was available when RP-1 V2 […] ⮪ nevermind, as Al₂Me₆ pointed out you have the latest version.
<queqiao-> ⟨night_beast⟩ yea, downloaded on 6/5 and the last relesae was on 5/19 (if the naming convention can be used)
<queqiao-> ⟨egg⟩ ⟪sichelgaita⟫ Funny, I thought that I had fixed the […] ⮪ You did. But in 3658, after ابن الهيثم.
<queqiao-> ⟨egg⟩ So this will be fixed (well, the error message will be clarified, the underlying issue is still open) in 伊藤.
<queqiao-> ⟨egg⟩ Which we need to build, uh, today.
<queqiao-> ⟨night_beast⟩ I guess this is going to have to do for now, and I'll have to come back and reset it in a year or so
<queqiao-> ⟨Al₂Me₆⟩ This ought to be called the clam orbit
<queqiao-> ⟨night_beast⟩ well I have something for the back side of the moon coverage now, so I can start planning those missions
<queqiao-> ⟨night_beast⟩ Interestingly enough, an S-Band antenna in L5 covers L1 to L2 almost exactly
<queqiao-> ⟨thunkii⟩ ⟪Al₂Me₆⟫ This ought to be called the clam orbit ⮪ relative of the tadpole
<queqiao-> ⟨thunkii⟩ i guess clam is what happens when the mass ratio is a bit smaller than earth/sun
<queqiao-> ⟨thunkii⟩ ⟪egg⟫ So this will be fixed (well, the error […] ⮪ https://en.wikipedia.org/wiki/Kiyosi_It%C3%B4

<queqiao-> ⟨test_account⟩ Principia download from bit.ly doesn't work. "bit.ly sent an invalid response."
<queqiao-> ⟨test_account⟩ I can download from the Chinese link though.
<queqiao-> ⟨test_account⟩ well, no, I can't, it asks for something in Chinese, likely some registration 😦
<queqiao-> ⟨the rocket science kid⟩ ⟪test_account⟫ well, no, I can't, it asks for […] ⮪ it shows up in english for me, but yes it is registration
<queqiao-> ⟨egg⟩ The bit.ly link works for me FWIW.
<queqiao-> ⟨test_account⟩ interesting

<queqiao-> ⟨test_account⟩ looks like my ISP issue; I can't access it on the stationary connection but can access on mobile
<queqiao-> ⟨test_account⟩ nevermind then
<queqiao-> ⟨the rocket science kid⟩ one of the past releases is Green, and another is l’Hôpital (doesn’t that mean hospital in French)
<queqiao-> ⟨egg⟩ It does.

<queqiao-> ⟨egg⟩ Will people be more confused by 伊藤 followed by 岩澤 than they were by Гельфанд followed by Гельфонд?
<queqiao-> ⟨test_account⟩ no )
<queqiao-> ⟨the rocket science kid⟩ 伊藤 and 岩澤 look completely different as kanji. Those two Russian names literally look identical. There is one letter of difference.
<queqiao-> ⟨the rocket science kid⟩ I know Chinese so I don't know how hard it is to read these characters to foreigners, but stuff in Japanese alphabet thingys look different enough that I can differentiate between them.

<queqiao-> ⟨egg⟩ * #σκοπός; see the README linked in the /topic for a general introduction, and the pinned posts for instructions to use the α.
<queqiao-> ⟨thunkii⟩ > This morning (Friday, June 16, 2023), the waning crescent moon was sighted in Blacksburg, VA (Lat: 37� 15' 40" N, Lng: 80� 26' 56" W, and elevation: 646 meters). I was at my sighting location by 5:13 am EST (moonrise: 4:25 am). The eastern horizon was partly cloudy with too much haze. Using a pair of binoculars (7X50), I started looking for the crescent. My first binocular sighting of the crescent moon was at 5:15 am....
<queqiao-> ... Then I saw it with the naked eye. The horns were approximately at 5:30 and 9:30 O'clock (5:30;7:30;9:30). I left the area at 5:43 am (sunrise: 5:54 am). At 5:35 am, the temperature, dew point, relative humidity, and pressure were 58.0 F, 58.0 F, 100%, and 29.85 in, respectively.
<queqiao-> ⟨sichelgaita⟩ 🇺🇸 got the first download.

<queqiao-> ⟨night_beast⟩ Any chance putting a Sat in L5 caused this? https://discord.com/channels/319857228905447436/845457276641738782/1119737055530987540
<queqiao-> ⟨night_beast⟩ It works... now if I can just figure out the LTP problem 😦
<queqiao-> ⟨fiora⟩ whats going on here
<queqiao-> ⟨egg⟩ huh.
<queqiao-> ⟨egg⟩ ⟪fiora⟫ whats going on here ⮪ A bug involving overloaded equality and OO, I think.
<queqiao-> ⟨egg⟩ Can you file an issue?
<queqiao-> ⟨fiora⟩ do you need a save file or just the issue filed?
<queqiao-> ⟨egg⟩ Just the issue with the screenshot, this is probably trivial to reproduce, and getting the save to run sounds extremely nontrivial.
<_whitenotifier-1adf> [Principia] FioraAeterna opened issue #3686: Incorrect "maneuver frame differs from plotting frame" message - https://github.com/mockingbirdnest/Principia/issues/3686
<queqiao-> ⟨egg⟩ A bug involving overloaded equality and […] ⮪ Or maybe something to do with the horrible hacks to reconcile the thing that uses -1 as a null value and the one that uses an empty array.
<queqiao-> ⟨fiora⟩ language designers: null pointer exceptions are a major cause of bugs and crashes. we should design languages without null
<queqiao-> programmers: -1 is now null
<queqiao-> ⟨fiora⟩ * #define NULL -1
<queqiao-> ⟨egg⟩ (we tend to be less messy than this, but this is the interchange stuff where we generate interop code that deals with ownership transfers between the C# and C++ from protocol buffers, so it gets complicated)
<queqiao-> ⟨egg⟩ (Background: Those protocol buffers are what the journal contains https://github.com/mockingbirdnest/Principia/blob/master/serialization/journal.proto, so we can replay what happened to the C++ without the game.)
<queqiao-> ⟨fiora⟩ hearing "protobuf" sent my brain back in time a decade, holy moley
<queqiao-> ⟨egg⟩ ⟪fiora⟫ hearing "protobuf" sent my brain back […] ⮪ Principia is full of those, the stuff that goes in the save (zipped and base-64ed) is protos
<queqiao-> ⟨fiora⟩ makes sense, serialization
<queqiao-> ⟨egg⟩ (proto2. We don’t do proto3.)
