This is the first time I enjoy a meme of this format / situation.
This feels like AI
In case you are serious: It’s probably not.
When you’re not careful with parallel processing / multithreading, you can run into something called a “race condition”, where results of parallel computations end up in the wrong order because some were finished faster than others.
The joke here is that whoever “programmed” this commic is bad at parallel progmming and got the bubbles in the wrong order because of that.
The image makes perfect sense if you read it in the order 3, 1, 2.🤦🏽♀️ Thanks for explaining, my brain must have corrected the race condition.
Regarding threads: I have had good experience with using thread safe queues everywhere to exchange data between threads, it’s the right tool in many cases, but I doubt queues to be useful when coding for performance.
Umm, queueing is standard practice particularly when a task is performance intensive and needs limited resources.
Basically any programming language using any kind of asynchronous runtime is using queues in their scheduler, as well.
Could be I was not clear when I wrote performance, I am talking about High Performance Computing, where you want to spend all CPU cycles on solving your problem. While taking Amdal’s Law into account. https://en.wikipedia.org/wiki/Amdahl’s_law
Apart from the fact that bubble 1 and 2 point to the wrong person.
I think that’s part of the joke too. Like the whole comic has been written out of order due to race conditions; rather than just the father represents race conditions.
It’s one degree of humour too far though, if that’s the case, doesn’t really land.
It definitely landed for me. The aspect of one thread coming out of a totally different routine for no reason was extra funny.
Oooh. Thanks for that, makes more sense now.
Not a lot of programmers on programmerhumor these days are there?
You have exactly 10 seconds to get the duck out of programmerhumor
Why is there a duck in your programmerhumor
They’re rubber-duck debugging
Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn’t work well for people on different instances. Try fixing it like this: !programmerhumor@lemmy.ml
I don’t get what’s supposed to be wrong here, it works on my machine
I am feeling confused with this meme. I am going to escalate this to my manager, secretly hopong he’ll tell me to do something else while he passes this on to the one dude in my team who’s worked with multithreading that one time.
good one! i have to admit I didn’t get it until I was browsing the comments and then it hit me 😀
I’m embarrassed to say I only finally got it now. After reading the joke last night. -_-;
You have NO IDEA how hard my autism hates you!

Why comment here at all
Because we’re programmers, and programmers are infamous for being rules-/logic-driven.
If, as a comment below suggests, the joke is that it’s meant to be read in order 3, 1, 2, that violates the rule that race conditions typically don’t cause an entirely different program to produce the output. So if the joke is meant to be “lol we have a race condition”, bubbles should be mixed up for one person, not mixed between people.
People don’t get the joke because the joke violates its own internal rules.
It doesn’t violate any rules… Imagine both the “speaker” and the “text” are being updated by separate threads. A program that would eventually display the behavior in this meme is simple, and I’m a bit embarrassed to have written it because of this comment:
#include <pthread.h> #include <stdio.h> char* speakers[] = { "Alice", "Bob" }; int speaker = 0; void* change_speaker(void* arg) { (void)arg; for (;;) { speaker = speaker == 0 ? 1 : 0; } } char* texts[] = { "Hi Bob", "Hi Alice, what's up?", "Not much Bob", }; int text = 0; void* change_text(void* arg) { (void)arg; for (;;) { switch (text) { case 0: text = 1; break; case 1: text = 2; break; case 2: text = 0; break; } } } int main(int argc, char* argv[]) { pthread_t speaker_swapper, text_swapper; pthread_create(&text_swapper, NULL, change_text, NULL); pthread_create(&speaker_swapper, NULL, change_speaker, NULL); for (int i = 0; i < 3; ++i) { printf("%s: %s\n", speakers[speaker], texts[text]); } }
