When some people say "Modern C++" they mean template meta-programming (traits, partial template specialisation, etc) as exemplified by Alexandrescu's book "Modern C++ design": http://www.amazon.com/Modern-Design-Generic-Programming-Patt... (note that I am not necessarily advocating such techniques, but understanding them will certainly help when you run across them in the wild).

The C++ FAQ is really helpful but doesn't seem to be updated to C++11 http://www.parashift.com/c++-faq/

Fortunately you can refer to Stroustrup's FAQ about C++11 http://www.stroustrup.com/C++11FAQ.html

For reference (like libc manpage, basic usage, which header to include): http://en.cppreference.com/
