Rediscovering C++

It's time to renew my C/C++ knowledge.
I spent many hours in C and C++ programming and today I'm going to be annoyed with that language. But programming languages are so similar to human languages: they change, evolve and surprise us!
So I'm looking for new aspects of C++ languages that I've never used or I don't know yet.
My first stop in this path is on SIMD and other techniques for fast numerical programming with gcc

I'd like to introduce in my coding style a new consciousness!
