If S is the stock return and M is the market return, then Beta = cor(S,M)*vol(S)/vol(M) Where cor(A,B) is correlation between A and B, and vol(X) is volatility of X (i.e. standard deviation).

Maybe I should have just said that I think GPU support would be a great addition. Distributed memory and GPUs are not mutually exclusive. Multi-GPU clusters are extremely common. In fact the latest devices (e.g. Tesla K10) have multiple GPU

Without GPU support I don't see how this is a good idea, if we are talking about HPC applications. Based on my understanding, a large number of dense matrix operations can be significantly accelerated in GPUs.

Xeon Phi is not for games. It could theoretically be used for accelerated software rendering but it does not have any video hardware (such as a DVI output connector).

const int * - pointer to const int I see this is as (const int)* foo; which is the same as (int const)* foo; And people prefer const int foo; over int const foo; So it all makes sense in terms of the grammar. Admittedly, it can be difficult

I think of Stroustrup's book as a reference manual. It is very comprehensive in covering the standard. Fact is that you don't learn to program by reading books any more than you learn to play a sport by reading books.

How about a picture of an F35 fighter jet? Because a fighter jet goes much faster than [insert your preferred hipster language]? Or, you know, the F35 uses C++ code (and not Python/Clojure/LISP/PHP/Ruby/whatever).
