@user-95 that's why I like programming - it's my favorite form of spelling.
i'm not very good at remembering all the names and the numbers, but I like to
think I can make things do a function.

That's why I like talking about things I'm interested in. It makes me more
likely to be able to bring up something I've been thinking about.

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.

@user-1074
the more you try, the more you have to calculate, which is a problem, because
endlessly recursive calculations create infinite loops, which frankly are
impossible to compute because they defy computation! Not good, not ideal, no
thank you, not for me, no thanks, not what I'd like.

I don't really need to know if people like me. It's nice, but it doesn't help

I do, however, desperately want to know if I'm helping. Knowing this would

part of me kinda wants to be the kind of nerd that writes down the names of
every file that's permanently stored on my computer so that I can verify in my
own handwriting or perhaps using a type of code that the files on my computer
were placed there intentionally and not used to discredit or implicate me in
something I had no intentions of being associated with
phew idk what that means but surely it's important
something something "file creation dates are just bits to be flipped"

wait until they learn what you've been working on while they were getting
better at... whatever they're more experienced in than you.
the computer pictures you post are legitimately some of the coolest I've
known! I don't exactly go looking for that kind of stuff because it's not my
thing, but I appreciate seeing all the neat stuff you're working on.
