Using shift to multiply is often a great idea on most CPUs.
Which CPU's are those? The fastest way to multiply today on AMD/Intel is to use the multiply instructions.
Didn't know that? yeah... it seems like only assembly language programs know this.
A mutex is a way of controlling access to a shared resource. Imagine you have a car with one key. If you and your sibling both want to use the car for the night, the key is the mutex. Whoever gets the key first gets to use the car until they put the key back.
But, wait, don't cars come with two keys ?
Now I'm confused.
Nothing in progression can rest on its original plan. We may as well think of rocking a grown man in the cradle of an infant. -- Edmund Burke
