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

@aeva god, on the 3rd day:
-
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?"
in a way magpie math is kinda refreshing, like imagine not throwing everything away every few years because of industry fads

@aeva I think part of it is we stopped trying to guess based on date and moved to measurements and short term extrapolation
-
the math's not quite right, but i managed to get the moon more or less working
@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

eee my copy of ｢The Astronomical Almanac 2025｣ arrived in the mail today while I was at work :D my hell spine hurts too much to be fussing with it tonight, but from flipping through it, it looks like it explains most of the information I've been missing and provides ample data to validate against <3

I'm so excited I'm gonna figure out where the moon is :O

@rygorous too much light pollution :(

@aeva it's probably for the best. Being an astronomer, it's a young man's game. If I were to eat something like that now, I'd be in a food coma for the rest of the day

@stefano Close one. Glad you made! It had rear traction, right? A bugger to regain control if traction gets lost.
It's a bit like a certain subtle sound I'll never forget. A very large wood construction- and timber market center right before my window of my childrens bedroom completely went up into flames in the middle of the dead night when I was young.
Much later, when my wife and me were living together one night I woke up by that subtle sound again and knew right away something big lit up. It was the bikeshed of our neigbours. We were able to call the FD and alerted the neighbours, who were still asleep at that point, to get out.🤷♀️

@robhardware excellent point Rob. I also feel that vanity metrics play a lot into it too... they are reluctant to leave behind a platform - and rebuild from scratch in a new place - if they had accumulated a lot of followers over the years.
IMHO it's all about optics and ego - even if X has armies of bots and engagement has plummeted for real users... when will they see the light?

Ieri su Radio Popolare è andata in onda una chiacchierata con me.

@elena @404mediaco @Em0nM4stodon Absolutely agree. I imagine there are quite a few politicians who instinctively feel they should be off X being advised by their political parties comms teams that they are losing a huge advertising opportunity, especially during elections, if they leave, and that they would be at a disadvantage to their opponents. Until the stigma of using X outweighs the electoral cost, I'm just not sure how much change we'll see.

@macfranc @lauramassera @eticadigitale beh, attenzione perché la Apple deve assolutamente garantire (quasi per contratto) ai suoi clienti la privacy e la protezione dei loro dati. Tanto da avvisare loro stessi diversi clienti che nemmeno si erano accorti di aver subito intrusioni e controlli attivi sui propri dispositivi offrendo persino assistenza legale. Difendono semplicemente il loro "feudo" dando protezione (finché conviene) ai loro protetti che continuano semplicemente a consumare gadget e giochini digitali. Della libertà e della privacy in sé non gliene importa nulla a nessuno, né a chi si lascia possedere né tantomeno alle grandi aziende come Apple.

Lavoratore muore per il freddo nei cantieri delle olimpiadi a cortina. “lo specchio del lavoro tossico e nocivo dei grandi eventi”
@anarchia
È morto per il freddo all’età di 55 anni Pietro Zantonini, originario di Brindisi, durante un turno di vigilanza notturna nel cantiere delle olimpiadi Milano-Cortina.

@lauramassera Hai assolutamente ragione, ma diciamo anche che nel 2025 è impossibile non riconoscere che la malvagità antisociale è il tratto distintivo di quelle Big Tech che spesso si presentavano eticamente candide.
L'unica eccezione è probabilmente quella di Apple che effettivamente ha deciso, sia anche solo per questioni di marketing e narrativa aziendale, di opporsi alle nuove tendenze del cattivismo trumpiano
