v.assign(&vv[0], &vv[0]+2);
Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:
template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N...
AES Encryption for an NSString on the iPhone
... that post includes this adapted code, which works for me, and seems a bit more straightforward. If you include their code for the NSData category, you can write something like this: (Note: The printf() calls are only for demonstrating the state of the data at various points — in a real applicatio...
What is a Java ClassLoader?
... a general class path as well as your application classes.
Since there is more than one class loader, they are represented in a tree whose root is the bootstrap class loader. Each class loader has a reference to its parent class loader. When a class loader is asked to load a class, it consults its ...
Which is faster: while(1) or while(2)?
...
Both loops are infinite, but we can see which one takes more instructions/resources per iteration.

What is a “surrogate pair” in Java?
... one or two "char" chunks (surrogate pair), and a grapheme could be one or more of those code points (i.e. a base character code plus one or more combining character codes, each of which could be one or two 16-bit chunks or "chars" long). So a single grapheme could be three combining characters eac...

This is now possible with WebAPI 2.1 (see the What's New):
