your video is 4 years old but I really appreciate your help

i was here

Incredible. I've learned so much from you! appreciate all your efforts!

very good video adn explanation

Based guy

Nice! Thank you!

Thanks a lot

literal saviour

When you used wnohang, the parent process finished before the child processes. But wouldnt that cause zombie processes, since the parent process is responsible for terminating its child processes?

I have never seen someone explain programming this good! Nice work! If there is ever a chance u do videos for c++, please do!

legit everyone at my school recommends to watch this series, crazy work

1:13 I didn't even know you could initialize struct values like that...

thanks man!!

For accessing variables accross threads shouldn't that be limited to stuff created on heap?

I think if you're using Cmake the dependent libraries options are automatically set for compile/link

19:31 thread works only when it gets a task, otherwise wait and release lock

CAN YOU DO A VIDEO FOR POINTERS

mutex here to protect the shared memory (Task queue) 14:36

also make sure 13:21 each thread would not executeTask when they have no task! (found ==1)

okok after one thread got the task, the release the lock for other threads to get the tasks. But at the same time, we want every tasks immediately execute after they got the task. So execute Task should be available at any time. (even if 2 or more thread got their tasks.)

in first method actually we using deque you can't iterate queue backward

did you make a separate playlist/course of such functions? if so, please let me know its name.

thank you for making it simple to graspe.

Hey CodeVault, thank you for giving me back my sanity. You and portfolio courses and so many lucid people online really serve as a nice place to refresh my mind after taking an online course for a certificate. Thanks a lot. I need this tutorial. Stay frosty!

Great analysis, thank you! I have a quick question: I have a SafePal wallet with USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). Could you explain how to move them to Binance?

7:15 It's important to notice that bytes are in reveresed order at each element. It's called small endian. For example if there wouldn't be small endian arrangement, the first element, 16, should be represented as { 00 00 00 00 00 00 00 10 }. Firstly it's not very noticeable in the case if you used 16,31,32,65 or other numbers that can be represented as a byte but if you exceed that byte, the small endian arrangement will be noticable. Ex. (unsigned) 256 would be { 01 00 } but with small endian representation it's { 00 01 }. So this program is only good for these small numbers.

So it's a pointer to a pointer?

Thanks!

Phenomenal video, thank you.

I made a nice improvements to this code. maybe wanna have a look? I set a max size of the car's fuel tank and made sure the fuel tank was full before the car leaves the filling station and also made the the filling station only signal the car only when there's enough for the car(i.e fuel > 40) at least to help improve understanding

in the fuel filling function, if you don't sleep after a single loop, it completes all 5 iterations before it signals the car routine thread. why's that so?? the signal is in the for loop. and since the code executes for each iterations.

so we can do execlp("bash", "bash", "-c", "ping ....") ; ?

what if we don't know the count?

brilliant explanation. not only did you explain how to use it, but also what happens to the code in the background as well. thank you so much

Thanks Sergiu! Would love to see your take on arena allocators in C

hello , why in this case the child process doesn't have 0 as process id ? . Thank you

Race conditions can occur in both single-core and multi-core systems, though they are more common and likely to cause issues in multi-core systems. Here’s why: Definition of a Race Condition: A race condition happens when multiple threads or processes access shared data or resources at the same time, and the outcome depends on the order or timing of their execution. Without proper synchronization, these concurrent accesses can lead to unpredictable and incorrect behavior. Multi-Core Processors: In multi-core systems, different cores can execute threads or processes truly in parallel. This means that if two threads are accessing the same variable, one thread may read the value before the other has completed its write operation, leading to inconsistent results. The parallel nature of multi-core systems amplifies the risk of race conditions, especially if synchronization mechanisms (like locks or semaphores) are not used. Single-Core Processors: Although single-core processors execute threads in a time-sliced manner rather than truly in parallel, race conditions can still occur here. This is because the operating system can switch between threads at any time, interrupting one thread in the middle of an operation and allowing another to execute. If this interrupted thread was working on shared data, a race condition can still result, despite the lack of true parallel execution. In short, race conditions are possible in both single-core and multi-core systems, but multi-core systems make race conditions more apparent and challenging to avoid due to true concurrent execution.

if i don't want to declare x as global, how can i pass the value of x to the function? when i try this "sa.sa_handler = &handle_sigusr1(x);", give me an error. The prototype of my function was void "handle_sigusr1(int x);"

I understood what you meant, but I didn't understand how each thread sees the correct index just because it allocated a space in memory. Doesn't each thread, when it starts and enters the function, run the risk of accessing the same index? Why didn't you use the mutex in this case? Excuse my English, I'm using the translator

ありがとうございます！

amazing, I cant find any other platform that breaks it down like this to help me understand, thank you!

bro just saved me litteraly 16 hours of lab sessions in around 5 videos

Awesome video bro you are bright

hey @CodeVault , your linked site is not working anymore. is it only for me, or its offline in general?

thank you sir

your video is awesome bro, thank you so much!

Thanks ^^

There is still an infinite loop in `startThread`, which never returns. Any solutions for this?
