Louis Brandy on why you should never trust a programmer who says he knows C++:
Programmers (especially those coming from C) can very quickly get up to speed in C++ and feel quite proficient. These programmers will tell you that they know C++. They are lying. As a programmer continues in C++, he goes through this valley of frustration where he fully comes to terms with the full complexity of the language.
Very true, and worth a look just for the diagram.
