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.
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
Half of the people posting here act like they are terrified of using threads. Then someone is explaining what a race condition is and they get 100+ upvotes like they just solved world hunger.
This feels like AI

lol your operating system is using queues and buffers with multiple threads everywhere.
Correct, and your point is?
My point is you don’t need to doubt the usefulness of queues 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.

Ah gotcha, fair enough. Definitely depends on the workload. If you have compute you want to dedicate to solely to a single task, have at it.
Not a lot of programmers on programmerhumor these days are there?

I don’t think it is, the joke is a bit poorly executed, but if you look at the text, the speach bubbles were made white by hand
