I've been coding for a bit, picked up a few things along the way, and more than happy to share them with others. I am currently working at Bloomberg L.P., all opinions and comments are my own.

C++11 ends the battle over 0 vs nullptr with 0_ptr:

inline constexpr
std::nullptr_t operator "" _ptr(unsigned long long int)
    { return nullptr; }

or 42_ptr if you prefer
