visual c++: #include files from other projects in the same solution
I am working on a game using Visual C++. I have some components in separate projects, and have set the project dependencies. How do I #include a header file from a different project? I have no idea how to use classes from one project in another.

C++ Tuple vs Struct
...
Uh... C++ has functions pointers, so template <typename C, typename T, T C::*> struct struct_less { template <typename C> bool operator()(C const&, C const&) const; }; should be possible. Spelling it out is slig...

...m/BCp5r), it scores 18.5 MB/s, about half the speed of sprintf. And with VC++ 2010, it gets about 50 MB/s, about twice the speed of sprintf.

return statement vs exit() in main()
...lly, there is a difference, but it's subtle. It has more implications for C++, but the differences are important.

Most C++ users are quite happy reading std::string, std::vector, etc. In fact, seeing a raw vector makes me wonder if this is the std::vector or a different user-defined vector.
I am always against using using namespace std;. It ...
Why no generics in Go?
... programmers being the result of no generics, slow compilers are caused by C++ like generics and slow execution times stem from the boxing-unboxing approach that Java uses.
The fourth possibility not mentioned in the blog is going the C# route. Generating the specialized code like in C++, but at ru...
