What is the difference between the states selected, checked and activated in Android?
... also that a call to ListView.setItemChecked() invokes the above. In other words, it could equally be called setItemActivated().
Prior to Honeycomb we had to implement workarounds to reflect state_checked in our list items. This is because ListView calls setChecked() ONLY on the topmost View in the ...

What's the difference between UTF-8 and UTF-8 without BOM?
...n, not divined." The heart and soul of the problem. +1, good sir. In other words: either standardize your content and say, "We're always using this encoding. Period. Write it that way.

Determining complexity for recursive functions (Big O notation)
...ll give us: T(n) = T(n-1-1) + 1 + 1 which is T(n) = T(n-2) + 2 or in other words we need to find our missing k: T(n) = T(n-k) + k. The next step is to take n-k and claim that n-k = 1 because at the end of the recursion it will take exactly O(1) when n<=0. From this simple equation we now know tha...
Using smart pointers for class members
...e, that weak_ptr is an observing pointer, not an owning pointer - in other words, it does not keep the pointed object alive if all other owning pointers to the pointed object go out of scope.
The advantage of weak_ptr over a regular raw pointer is that you can safely tell whether weak_ptr is dangl...
