unique_ptr and rvalue question
I have a unique_ptr type: typedef std::unique_ptr<int, void(*)(int*)> unique_fd; In a function that returned unique_fd I use it like this: unique_fd u_sock = make_unique_fd(sock); if (bind(*u_sock, cur_addr->ai_addr, cur_addr->ai_addrlen) == 0) return u_sock; GCC ... 29 Mar 2010 16:56

const is an overrated concept that is a source of extra typing and maintenan

The D programming language has const. It differs from C++ const in that D cons... 28 Mar 2010 20:04

Using template parameters to simplify interfaces
I'm wondering if there is any mileage in the idea of using template parameter/arguments solely for the purpose of reducing the clutter of an interface. To give a contrived example, suppose that I am modelling a system that comprises a known collection of members of the system and that I am only interested in how t... 29 Mar 2010 02:35

Template aliases with default arguments and parameter packs
Is it allowed to use default template-arguments and template parameter pack in templated alias declaration? template <class T, class... Types> struct X { typedef typename T<Types...>::type type; }; // is it legal? template <class T = void, class... Types> using A... 27 Mar 2010 16:31

Project to recover UnderC C/C++ interpreter
Hello ! I'm managing to update UnderC C/C++ interpreter to work with modern c+ + compilers, actually it works on windows with gcc 4, compiles on linux but doesn't work properly, and crash with vc++ 2008. I think that will be a great framework having FLTK and UnderC working together, will be easy to prototype/e... 26 Mar 2010 13:08

Shift/Move Decimal Place
Hi, I just wonder whether there is an efficient way to shift/move the decimal place of a double by x (an int) to the left without losing precision. e.g. shifting the decimal place of 11096.2345 by 2 => 110.962345 Thanks in advance. -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] ... 26 Mar 2010 10:20
