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

@feritae thank you!!! 🙏
honestly one thing that greatly improved my experience of the Fediverse was following the hashtag 3GoodThings.
I’m hoping GratefulForYou will have the same effect.
And I feel so much gratitude towards Fedi people that turning this into a daily sign of appreciation already makes me smile 😊

@bleeptrack it's amazing that this thing exists?!

Weird things I bought recently: a camera cooler 💀
Basically a thermoelectric heat pump + fan and battery that snaps to the back of my Sony cam.
Turns out: if you shove smart tracking things into a tiny full frame camera and run for more than 20mins, this thing starts to melt and shuts off. ☀️

@gumnos thank you Tim ❤️

Ma si son mangiati tutto loro? 😱🤪

@comandante_virgola @carlux vuoi dire che son morti i Daikin o i pannelli ? Perché i pannelli solari molti dicono che salvo disastri durano parecchio…
I Daikin mi sa che mi toccherà metterne uno almeno per la camera da letto. Nonostante mura molto spesse in pietra quando un’ondata di calore dura una settimana il caldo si sente egualmente. Per ridurre le spese del gas oltre a tener la temperatura in casa a 19 C metterò una stufetta a pellet…. Mannaggia a tutte ste spese 😩
