Maximum number of characters using keystrokes A, Ctrl+A, Ctrl+C and Ctrl+V
...
@marcog - your notation is at least confusing and at most wrong. n is the keystrokes you're allowed to use. You have to compute how many As you can type with n keystrokes. So 7 => 7 makes no sense.

Constant Amortized Time
...e last enlarge. But you've also waited twice as long before doing it! The cost of each enlargement can thus be "spread out" among the insertions. This means that in the long term, the total time taken for adding m items to the array is O(m), and so the amortised time (i.e. time per insertion) is O(1...
How do exceptions work (behind the scenes) in c++
...viously a lot of overhead in actually throwing and catching an exception. Most of it is hidden within __cxa_throw, which must:
Walk the stack with the help of the exception tables until it finds a handler for that exception.
Unwind the stack until it gets to that handler.
Actually call the handler...

How do I style a dropdown with only CSS?
...right-hand-side of the div.
The advantage of this approach is that it is cross-browser (Internet Explorer 8 and later, WebKit, and Gecko). However, the disadvantage of this approach is that the options drop-down juts out on the right-hand-side (by the 20 pixels which we hid... because the option e...
Realistic usage of the C99 'restrict' keyword?
...aliasing, enabling better optimization by the compiler.
For instance, suppose I have a machine with specialized instructions that can multiply vectors of numbers in memory, and I have the following code:
void MultiplyArrays(int* dest, int* src1, int* src2, int n)
{
for(int i = 0; i < n; i++...
When should one use a spinlock instead of mutex?
...e lock won't be unlocked either. IOW, a spinlock wastes only CPU time on those systems for no real benefit. If the thread was put to sleep instead, another thread could have ran at once, possibly unlocking the lock and then allowing the first thread to continue processing, once it woke up again.
