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

@jon_valdes @dotstdy though I guess the corner the intel case is cutting is where the slope starts to level out so I guess that makes sense. are CPU trig functions just as bad?

@jon_valdes @dotstdy would mollytime get a warmer, fuller sound if i switched to expensive software sine waves :3

@aeva @jon_valdes generally cpu trig is not so bad, but does vary between platforms if you're just calling the c stdlib functions (but we're talking differences of 1 ulp or so). so yes, absolutely you can get a warmer fuller soundstage by switching to a different sin.

@dotstdy @jon_valdes maybe I'll call the expensive exact soft sin oscillator "gold plated sin"

@demofox @dotstdy @jon_valdes well so far I can't tell the difference by ear between the soft sin and the double precision sin that clang gives me

@demofox @dotstdy @jon_valdes assuming I didn't screw anything up adapting Jon's shader toy, the 30 iteration soft sin also has the surprising property of being able to clip out of the expected -1.0 to 1.0 output range https://github.com/Aeva/mollytime/blob/af58e9237903856b6193a116ae6408038dc47d4a/src/patch.cpp#L319

@aeva @demofox @dotstdy @jon_valdes There's lots of versions of CPU sin/cos as well. The fastest is basically identical to the GPU one - about 12 bits of precision, IIRC. Then they do iteration internally if you want higher precision. There's no magic - everything costs!
As you noticed, sometimes it's better not to call sin-vs-cos, because you're not guaranteed to get magnitude 1.0. In those cases it's better to get sin and derive the other by doing sqrt(1-sin^2).

@aeva @demofox @dotstdy @jon_valdes Also, if you care about precision at all, do range reduction yourself beforehand. Otherwise you have no idea how it's being done internally.

@TomF @demofox @dotstdy @jon_valdes I already do the range reduction. I learned that the hard way once upon a time XD

Ho una buona opinione di Chiara Valerio, la trovo sempre molto attenta al tema delle varie identità e che se ne porti rispetto. La ascolto anche per saperne di più in merito. Mi è chiaro che, essendo in linea con la lingua che mi definisce, mi avvalgo della fortuna di non sentirmi esclusa. Non significa però che voglia appositamente ignorare o negare che esistano altre identità, perchè non uso la schwa. Penso pure che non esiste termine per un genitore che perde il figlio.

@evadm le recensioni non ne parlano benissimo...

Riescono a rigirare qualsiasi cosa a loro vantaggio, temo siano imbattibili.
Nel Regno Unito sono necessari uno "scioglimento del Parlamento" e un "cambio di governo". Lo ha detto Elon Musk in videocollegamento col palco della manifestazione organizzata dall'estrema destra a Londra. "Non si può: non abbiamo altri quattro anni, o quando ci saranno le prossime elezioni, è troppo tempo. Bisogna fare qualcosa", ha dichiarato il tycoon riferendosi all'esecutivo laburista di Keir Starmer con cui in passato è entrato più volte in polemica. Ha poi dichiarato che "la sinistra è il partito della violenza e dell'omicidio", riferendosi all'assassinio di Charlie Kirk negli Usa.

Also fuck you Musk wearing a "What Would Orwell Think"
I don't think it's putting Orwell on a pedestal or really even saying anything extreme about him to say that Orwell would think "fuck fascists", he literally wrote some of the most famous books in the canon about authoritarianism, some of which are being *banned* by right-wing groups right now
