How many Activities vs Fragments?
...Also what I have read about the ActionBarSherlock is that it seems to work best with Fragments instead of Activities (but I have not worked with it yet).

Iterate through pairs of items in a Python list [duplicate]
...a stream of data (i.e. array access); rather, it only needs to ingest each item once, and caches it for the next evaluation. So if you have, say, a Twitter firehose, you don't ever need to read the firehose into a gigantic (perhaps infinite-length) array for this to work.

SearchView's OnCloseListener doesn't work

Looping through array and removing items, without breaking for loop
I have the following for loop, and when I use splice() to remove an item, I then get that 'seconds' is undefined. I could check if it's undefined, but I feel there's probably a more elegant way to do this. The desire is to simply delete an item and keep on going.
