Any reason why scala does not explicitly support dependent types?
...
Syntactic convenience aside, the combination of singleton types, path-dependent types and implicit values means that Scala has surprisingly good support for dependent typing, as I've tried to demonstrate in shapeless.
Scala's intrinsic support for ...

What does T&& (double ampersand) mean in C++11?
...ntax is now legal:
T&& r = T();
rvalue references primarily provide for the following:
Move semantics. A move constructor and move assignment operator can now be defined that takes an rvalue reference instead of the usual const-lvalue reference. A move functions like a copy, except it ...

...r, which will persist (there is no LogOut-like feature here), some server-side additional CPU consumption, and the fact that the user-name and password are transmitted (over HTTPS) into the Server (it should be more secure to let the password stay only on the client side, during keyboard entry, and ...
Scala: Abstract types vs generics
...uld argue that this distinction is fairly arbitrary.
The Scala Way
We decided to have the same construction principles for all three sorts of members.
So you can have abstract fields as well as value parameters.
You can pass methods (or "functions") as parameters, or you can abstract over them.
Yo...
Why does struct alignment depend on whether a field type is primitive or user-defined?
...
I think this is a bug. You are seeing the side-effect of automatic layout, it likes to align non-trivial fields to an address that's a multiple of 8 bytes in 64-bit mode. It occurs even when you explicitly apply the [StructLayout(LayoutKind.Sequential)] attribute. T...
Why is a round-trip conversion via a string not safe for a double?
...ber is pretty simple -- it just calls _ecvt, which is in the C runtime:
void DoubleToNumber(double value, int precision, NUMBER* number)

WRAPPER_CONTRACT
_ASSERTE(number != NULL);
number->precision = precision;
if (((FPDOUBLE*)&value)->exp == 0x7FF) {
number->...
