I just ran into a case where clickable children in the scrollview can grab the touch events and onScroll won't get called at all. Otherwise, thanks, great ...
Difference between core and processor
...t the single CPU into two virtual CPUs i.e we have two cores for our task. Now the CPU is single, but it is only pretending (masqueraded) that it has a dual CPU and performs multiple tasks. But having real multiple cores will be better than that so people develop making multi-core processor i.e. mul...

...aid ride, but there may be rides being underutilized elsewhere. If you are now able to ride these rides as well as the rides you have to wait on, then you can increase the overall efficiency of the park.

What is the best way to get all the divisors of a number?
...ad of n/2.
I will give you example so that you can understand it easily. Now the sqrt(28) is 5.29 so ceil(5.29) will be 6. So I if I will stop at 6 then I will can get all the divisors. How?
First see the code and then see image:
import math
def divisors(n):
divs = [1]
for i in xrange(2,...
