What is uintptr_t data type
...y means that it's the same size as a pointer.
It is optionally defined in C++11 and later standards.
A common reason to want an integer type that can hold an architecture's pointer type is to perform integer-specific operations on a pointer, or to obscure the type of a pointer by providing it as a...
Is std::unique_ptr required to know the full definition of T?
...
Adopted from here.
Most templates in the C++ standard library require that they be instantiated with complete types. However shared_ptr and unique_ptr are partial exceptions. Some, but not all of their members can be instantiated with incomplete types. The motivatio...
What can I do with a moved-from object?
...
17.6.5.15 [lib.types.movedfrom]
Objects of types defined in the C++ standard library may be moved from
(12.8). Move operations may be explicitly specified or implicitly
generated. Unless otherwise specified, such moved-from objects shall
be placed in a valid but unspecified state.

Do c++11 lambdas capture variables they don't use?
...ble is not captured. In your example, my_huge_vector is not captured.
Per C++11 §5.1.2[expr.prim.lambda]/11:
If a lambda-expression has an associated capture-default and its compound-statement odr-uses this or a variable with automatic storage duration and the odr-used entity is not explicitly c...
What happens to a detached thread when main() exits?
...n signal handlers may execute ([basic.start.term]/1, 1st sentence). Of the C++ standard library, that is only the <atomic> library ([support.runtime]/9, 2nd sentence). In particular, that—in general—excludes condition_variable (it's implementation-defined whether that is save to use in a s...
Why does C++11's lambda require “mutable” keyword for capture-by-value, by default?
...
This is a good point. I totally agree. In C++0x though, I don't quite see how the default helps enforce the above. Consider I am on the receiving end of the lambda, e.g. I am void f(const std::function<int(int)> g). How am I guaranteed that g is actually refere...
Why do you have to link the math library in C?
...or this libm/libc split, none of them very convincing.
Interestingly, the C++ runtime libstdc++ requires libm, so if you compile a C++ program with GCC (g++), you will automatically get libm linked in.

What Every Programmer Should Know About Memory?
