What is the purpose of the “final” keyword in C++11 for functions?
...ady mentioned in a comment is that if you are overriding a function from a base class, then you cannot possibly mark it as non-virtual:
struct base {
virtual void f();
};
struct derived : base {
void f() final; // virtual as it overrides base::f
};
struct mostderived : derived {

Conveniently Declaring Compile-Time Strings in C++

Fastest way to determine if an integer's square root is an integer
... doing a bit-wise "and." Perfect squares can only end in 0, 1, 4, or 9 in base 16, So for 75% of your inputs (assuming they are uniformly distributed) you can avoid a call to the square root in exchange for some very fast bit twiddling.

You commonly see MD5 values represented in hex, however WordPress uses Base64 instead. Your hex value would be sZRqySSS0jR8YjW00mERhA== in Base64, which uses 25% less characters than hex ...
