Here's how the error looks while the installation: An error occurred during the setup process of the feature Attempted to perform an unauthorized operation. Clicking on Retry doesn't help, if I click on the Cancel button, it continues but then there will come up more errors like this one: NOTE: I'm not using any VM, I'm using Windows 7 Ultimate 32 bit as my OS.

Consider http://en.cppreference.com/w/cpp/experimental/when_any . The following is just a naive and simplified implementation: #include <future> template<typename Iterator> auto when_any(Iterator first, Iterator last) { while (true) { for (auto pos = first; pos != last; ++pos) { if (pos->is_ready()) { return std::move(*pos); } } } } I am not satisfied because it is a busy polling in an infinite loop. Is there a way to avoid busy polling? A polling free version would launch 1 thread per future and have them set a condition variable with which future is ready. Then you "leak" the threads until

Why is the first expression allowed, but the second not: void test() { int a; ++a = getSomeInt(); a++ = getSomeInt(); } I mean, why its forbidden for the second one to be an lvalue ? The second one makes sense and the first not. In the first one we increment the variable and immediately after we gave here a new value, we lose it. That's not the case in the second expression. It makes sense to assign some value and increment the variable after that. The result of postfix increment is prvalue which mean pure rvalue so it is not modifiable. This is per the draft C++ standard under postfix

Even though all major operating systems and programming languages/APIs have had locale support for at least a couple of decades, it seems that JavaScript still does not! With JavaScript becoming more and more of a full application programming language both in the browser and on the server, the lack of real locale support is becoming a real problem. Are there any proposals to add locale support as it exists in other languages to the EcmaScript standard? As part of the "harmony" project or anywhere else? I'd like to support and evangelize any such proposal. (This is a followup to my previous

Declaring a struct with typedef typedef struct some_struct { int someValue; } *pSomeStruct; and then passing it as a parameter to some function with const declaration, implying 'const some_struct * var' void someFunction1( const pSomeStruct var ) turns out to become some_struct * const var This is also stated in Section 6.7.5.1 of the ISO C standard which states that 'const' in this case applies to the pointer and not to the data to which it points. So the question is - is there a way to declare a pointer to a const struct in a shorthanded notation with typedef, or there must always be a
