    These dumbass people saying your English is bad and stuff like that. Fuck 'em. The most important thing you are doing is sharing knowledge and you could have done that in your own language but you chose English. Thank you so much for that. Highly appreciated!

    In case of semaphore, if the two threads accessing a shared resource, there will be race condition. Can tell, in this case, how synchronization is achieved?

    Thanks for the video, but please buy a good microphone. If video quality is bad thats one thing but audio quality should always be good, otherwise people tune out quickly.

    Very good explanation! Crisp and clean .
  • Vishal Gupta
    is mutex used in dining philospher problem?
  • Coque JC
    I love u mate
  • Ovi Hussain
    The only issue with your explanation is that when a mutex is locked, another thread trying to access the mutex doesn't get returned an error as you say. It just waits until the mutex is unlocked. I think you get it, just worded it improperly. Otherwise good video.
