....... yeah you're probably right. I could never get it working for some
reason. Only Alsa worked, and Alsa is arcane to configure :ms_confused:

Pretty sure I use ALSA, but I might have installed Pulseaudio for
compatibility reasons. I'll see

hehe if I don't understand how it works it's difficult for me to use things.
My Linux friends get so exasperated with me because I'm like "cool script
gimme like 2 days to figure it out" and they're like "bro just use these
flags" and I'm like "no"

I always get a little suspicious when my machine pseudo-randomly starts
running the fans super loud and when I open my resource monitor they suddenly
drop to silent
like... bro what are you hiding

Hi, I'm learning about semaphores right now and trying to explain them to a
friend. But I only sorta understand how they work - can anyone look at this
pseudocode and tell me if I'm on the right track?
![Some C pseudocode working through the semaphore design pattern. Here's the text of the pseudocode: /* no lock example */ void start_thread(int* x) { *x += 1; } int main() { int x = 0; for (1000 times){ start_thread(&x); } print(x); } /* in this case you have no idea what will print because thread A will take x and be like "ah yes it's 423" and then in the next instruction it'll be like "I'll increment this to be 424" and in the next one it'll say "okay now it's time to store 424 in the variable X" but like... there's a thousand threads all doing that at the same time, so odds are you'll have 5 that are like "ah yes this is 423 I'll set it to 424" */ /* not a good plan. Need a lock, so only one thread can use it at once. */ /* mutex example: */ void start_thread(int* x, int* x_mutex) { *x += 1; *x_mutex = 0; } int main() { int x = 0; int x_mutex = 0; for (1000 times){ while (x_mutex != 0){ } /* do nothing */ x_mutex = thread_id; start_thread(&x, &x_mutex); } print(x); } /* this should print 1000, but it's basically as slow as doing it single threaded. */ #define MAX 10 void start_thread(int* x, int* x_semaphore) { *x += 1; *x_semaphore += 1; } int main() { int x[MAX]; int x_semaphore = MAX; for (1000 times) { for (int i = 0; i < MAX; i++) { x_semaphore -= 1; start_thread(&x[i], &x_semaphore); } while (x_semaphore != MAX) { } /* do nothing */ } int value = sum(x, MAX); print(value); }](/similar-different/media/224b236a8660c34a.png "Some C pseudocode working through the semaphore design pattern.

yeah uhhhh the one you helped me setup. The error is just "connection refused"
because it "could not write header for output file" because of incorrect input
parameters, but I don't think I changed anything since we used it a couple
weeks ago. Have you seen any errors like that?

@user-36 ideally you'd convert to an arbitrary base (in this case 9) and shift
from there, but shifting two places might work. idk I haven't thought about it.
