What is the difference between the following concepts in layman terms: spinning lock, blocking and condition?
(If your GF doesn't already know this, she should be made aware that CS colleges are the most prolific users of plagarism detection software in the free world.)
Spinning lock:
To quote Lisa and Bart: "Are we there yet? Are we there yet? Are we there yet?" - cute in small quantities, extremely annoying in large doses.
Blocking:
The gate at the starting line of a horse track, or the locked door at a store before a product launch work as examples of blocking operations. You can't get your new iPad until some guy in a black t-shirt opens the door.
Condition:
Don't do anything (or keep doing what you're doing) until you hear otherwise from me.
