i nerd sniped myself tonight and i imagine the NSA operative who is assigned to me is very confused by the increasingly erratic and frustrated google searches for HOW DO I CALCULATE THE MOON WHERE IS THE MOON
-
astronomy math is out of this fucking world btw like want to know where the moon is? great buckle up you're in for a few hundred years of bizarre hacks and lots of exciting questions like "wait, why are they using the julian calendar?"
@aeva I think part of it is we stopped trying to guess based on date and moved to measurements and short term extrapolation
-
@aeva wait, is it your fault that we’re losing the moon in however many millions of years?
-
ok so back to the moon thing, i found another resource and i think i understand the why behind the asinine coordinate systems a little better but it also glosses over the math so it's kinda useless at the same time. i'm tempted to just make shit up and move on, but it would bother me that the function was wrong if i did that
@aeva This is why we threw our hands up and said, just use what's already been done. We outsource "where are the space things" to NAIF SPICE: https://naif.jpl.nasa.gov/naif/aboutspice.html (there's also the rust rewrite, ANISE, but we don't trust that at my place of work yet)

@c0dec0dec0de it might not be!

@squirrelbaffler it occurred to me that this is one of those situations where one would probably normally use a library, but the problem is I need to prioritize speed over accuracy because it's repeatedly invoked in a real time audio thread, a use case which i'd not expect to be shared by serious scientific or industrial use cases

I warn you though, if I see the moon is broken tonight, I'll be complaining to you about it.

@CliftonR I will happily accept moon-related bug reports

@aeva at least now we have the J2000 epoch, which kiiiiinda hides away a bit of the old cruft... but yeah, it's pretty wild.
On the other hand, thanks to these whacky calendar conversions they can apparently use observations made by Chinese astronomers 2000 years ago, so hey, maybe they have a point

@jon_valdes tbh i respect that modern astronomers decided this was fine and didn't go and add new problems to the pile

@generalespecifico @pare E così, posso continuare a non giocare esattamente come già facevo prima 😅

@generalespecifico io vinco sempre un importo pari a quello dei biglietti che non ho comprato. Poi, succedono anche cose divertenti, come il fatto che prendevo in giro i miei colleghi che giocavano al Gratta e Vinci nel bar dove andavamo a prendere il caffè. Poi quando me ne sono andato dal lavoro e mi hanno fatto un regalo erano avanzate delle quote e per prendermi simpaticamente per il culo hanno speso i €20 che restavano in biglietti del gratta e vinci. E ho vinto 135 euro 🤣

@matz perché nella meravigliosa società neoliberista tutti i costi (non solo economici) della produzione sono esternalizzati sul singolo individuo e sull'ambiente (e anche sulle generazioni future, va').

@Ihazchaos thank you! I love to see the hashtag in action. This and 3GoodThings are brightening up my feed 😊
