I saw it on careercup.
"How do you think the updates on facebook work? What kind of a data
structure do you think they use? How would you be linked to your friends
updates?"
one reply is
"use hash table to find changes, use observer pattern to inform changes to
all user who is publishing the article"
Could someone give me some detail or reference? Thanks a lot.
