Iterate through the fields of a struct in Go
...ce value then represents the
value of the field.
There is no function to convert the value of the field to a concrete type as there are,
as you may know, no generics in go. Thus, there is no function with the signature GetValue() T
with T being the type of that field (which changes of course, depe...

Does Flask support regular expressions in its URL routing?
I understand that Flask has the int, float and path converters, but the application we're developing has more complex patterns in its URLs.

How is “int* ptr = int()” value initialization not illegal?
...o zero or a prvalue of type std::nullptr_t. A null pointer constant can be converted to a pointer type; the result is the null pointer value of that type and is distinguishable from every other value of object pointer or function pointer type. Such a conversion is called a null pointer conversion. [...

Weird Integer boxing in Java
...ion code is handled by the compiler.
So during compilation phase compiler converts Integer a = 1000, b = 1000; to Integer a = Integer.valueOf(1000), b = Integer.valueOf(1000);.
So it is Integer.valueOf() method which actually gives us the integer objects, and if we look at the source code of Integ...
