What should I use Android AccountManager for?

I've seen AccountManager in the Android SDK and that it is used for storing account information. Thus, I cannot find any general discussion of what it is intended for. Does anyone know of any helpful discussions of what the intention behind AccountManager is and what it buys you? Any opinions of wha...

Usually, you end up with a combination of the options below that best fit your needs. The following provides some in-depth reading: One more Nested Inte...

What is a plain English explanation of "Big O" notation?

Quick note, my answer is almost certainly confusing Big Oh notation (which is an upper bound) with Big Theta notation "Θ" (which is a two-side bound). But in my experience, this is actually typical of discussions in non-academic settings. Apologies for any confusion caused. BigOh complexit...

What do "branch", "tag" and "trunk" mean in Subversion repositories?
