Lecture 3, Unit 1: Introduction to condition variables and monitors 

nice tutorial but why upload this in 240p? can't see the text very well.

It's people like you that empower me to pass my exams without a tutor. Thank you so much!

This is pretty useful, thanks for uploading all these

Very helpful video, even though the text is hard to read. I appreaciate it

can i get the ppt as text is not visible

Wish my teacher could make it this simple. Thank you!!!!!

Very clear explanation... Thank you sir

Nice tutorial.

God bless you!

Thanks a lot !

can we get the PPT used in this video?

why only 240p

thanks a lot...

// General use of signal struct counter { int count; pthread_mutex_t lock; pthread_cond_t above_zero; }; void increment(struct counter *c){ pthread_mutex_lock(&c->lock); int n = c->count; c->count = n+1; pthread_cond_signal(c->above_zero); pthread_mutex_unlock(&c->lock); } void decrement(struct counter *c){ pthread_mutex_lock(&c->lock); int n = c->count; c->count = n+1; pthread_mutex_unlock(&c->lock); } void print_val(struct counter * c){ pthread_mutex_lock(&c->lock); if(c->count above_zero,&c->lock); } printf("Value = %d ",c->count); pthread_mutex_unlock(&c->lock); } /* Problem: no guarantee signal thread runs right away: * c->count = -1; * T1 : increment // c->ount = 0; * T2 : print_val // c->count = 0, waits * T3 : increment // c->count = 1, signals * T1 : decrement // c->count = 0 * T2 : wakes up // c->count = 0 WRONG */

the resolution is terrible

Resolution is terrible. You broke my eyes

Sir wtf is 240p video :(

thank you so much for sharing all these but please speak just a little slower and more clear to let us think about

The text can't be seen, and the flow is too quick and monocord

Can you say one more time that major facility of the monitor is the mutual exclusion? If you would not repeat things 100 times, your video would have been lasting for 5 minutes

Such a pathetic teacher this guy. Can put anyone to sleep.
