what if I made a little visual programming language for my synthesizer 🤔

I switched pygame from initializing everything by default like they recommend to just initializing the two modules I actually need (display and font) and the audio thread time dropped, probably because now it's not contending with the unused pulse audio worker thread pygame spun up. The typical patch sample eval is about 1.5 microseconds now, and a full batch is now under a millisecond.
tracy is a good tool for profiling C++, but the python and C support feels completely unserious :/

making building with cmake a requirement to use the python bindings and then only providing vague instructions for how to do so is an odd choice.

using cmake is a bridge too far, so I figure I'll just mimic what the bindings do, but it turns out they're a bit over engineered as they're meant to adapt C++ RAII semantics to python decorators and I don't want to pay for the overhead for that when I could just have a begin and end function call to bind instead. that probably will have to be wrapping new and delete like they do though because there is no straight forward C call for this.

The relevant C APIs are provided as a pile of macros that declare static variables that track the context information for the begin and end regions. This seems to be on the theory that you would never ever ever want to wrap these in a function for the sake of letting another language use them in a general purpose way. The inner functions they call are all prefixed with three underscores, which is basically the programmer way of saying "trespassers will be shot without hesitation or question"

also there's this cute note in the docs saying that if use the C API it'll enable some kind of expensive validation step unless you go out of your way to disable it, which you shouldn't do but here's how 🙄

C++ RAII semantics are so universally applicable to all programs (sarcasm) that even the C++ standard library provides alternatives to scope guard objects if you don't want to use them. come on man

tragic. pygame.display.flip seems to always imply a vsync stall if you aren't using it to create an opengl context, and so solving the input events merging problem is going to be a pain in the ass. it is, however, an ass pain for another night: it is now time to "donkey kong"
EDIT: pygame.display.flip does not imply vsync! I just messed up my throttling logic :D huzzah!

ideally the ordering of those events would be represented in the patch evals but they just happen as they happen. It's plenty responsive with a mouse though. I'll have to try out the touch screen later and see if the problem is basically solved now or not.

ok I can go ape shit with a mouse and it works perfectly and like I mean double kick ape shit, but the dropped events problem still persists with the touch screen ;_;

it's possible that I'm doing something wrong with the handling of touch events and it's something i can fix still, but now i'm wondering if there's a faster way to confirm if "going ape shit" playing virtual instruments is a normal intended use case for touch screen monitors by their manufacturers and the people who wrote the linux infrastructure for them, or if they all were going for more of a "tapping apps" vibe

and by "going ape shit" i just mean gently flutter tapping two fingers rapidly to generate touch events faster than i could with just one finger, such as to trill between two notes or repeatedly play one very quickly. doing that on one mouse button to generate one note repeatedly very fast feels a lot more aggressive

if i do the same on my laptop's touch pad (which linux sees as a mouse) the same thing happens, but if I really go ham on it such that it engages a click with the literal button under the touch pad, then the events all go through just fine. this is why i'm starting to think there's some filtering happening elsewhere

i wonder if there's a normal way to ask linux to let me raw dog the touch screen event stream without any gesture stuff or other filtering, or if this sort of thing isn't allowed for security and brand integrity reasons

someone brought up a really good point, which is that depending on how the touch screen works, it may be fundamentally ambiguous whether or not rapidly alternating adjacent taps can be interpreted as one touch event wiggling vs two separate touch events
easy to verify if that is the case, but damn, that might put the kibosh on one of my diabolical plans

ok great news, that seems to not be the case here. I made little touch indicators draw colors for what they correspond to, and rapid adjacent taps don't share a color.
bad news; when a touch or sometimes a long string of rapid touches is seemingly dropped without explanation, nothing for them shows up in evtest either D: does that mean my touch screen is just not registering them?

side note: if you try to use gnome's F11 shortcut to take a screen recording, it doesn't give you the option to pick which screen, and it just defaults to recording the main screen. i assume this too is security

I want to add a pair of instructions for switching between (0, 1) range and (-1, 1) range. so
u = s * .5 + .5
and
s = u * 2 - 1
what are good short names for these operations?
EDIT: can be up to three words, less than 7 letters each preferably closer to 4 each

ok thanks to the magic of variable width font technology, "unipolar" squeaks in under the limit despite being 8 letters

@katttivizzima da sempre, le persone dotate di una buona padronanza della lingua, quando devono scrivere velocemente dei testi descrittivi o esplicativi, tendono a concentrarsi sul contenuto e a lasciar andare, quasi in autonomia, il flusso scrittorio sulla base del patrimonio linguistico assimilato, generando varianti di frasi già sentite; inoltre, invece che impiegare più subordinate, indulgono sui punti elenco. In pratica fanno già quello che gli LLM sono programmati per fare

That's what I keep doing. *fingers crossed*

@alberto_cottica @mora @FlaviaMarzano Alla prova dei fatti molte persone si scoraggiano prima. Spesso restano soprattutto quelle che hanno la fortuna di entrare in un’istanza dove trovano subito persone con interessi in comune, con cui riescono ad allargare la propria rete.
Per molti altri, invece, l’esperienza iniziale può essere piuttosto desolante, nei primi giorni si vede poco movimento, si conosce quasi nessuno e non è facile orientarsi. Ed è proprio in quella fase che tanti abbandonano.

Prof @Adrianogallina ma che fine ha fatto https://untempoperpensare.wordpress.com/ ? Ha smesso di scrivere? Lo sa che puó collegare il sito al fediverso? https://m.youtube.com/watch?v=t4pmWufYRr0&pp=ugMGCgJpdBABugUEEgJpdMoFFXdvcmRwcmVzcyBhY3Rpdml0eXB1YtgHAQ%3D%3D
Lo fece tempo fa @WhiteJolly con il suo @get-backs.com ma adesso si è preso una pausa… chissà perchè 🤔

Un mio contatto autore, si è lamentato che in molti gli hanno scritto che i suoi testi sarebbero stati prodotti da IA.
Lui dice di averli scritti di suo pugno.
Così ha passato un capitolo di un suo romanzo al sw che individua scritti da parte di IA. il responso: 76% è opera di IA.
Cosa a suo dire non vera.Non sono solo gli umani che non sanno valutare l'origine genuina di un testo. Non lo sa fare neppure un software studiato appositamente per quello scopo.
