How can I use interface as a C# generic type constraint?
...nHolt: I think think the creators of .NET, in deciding what constraints to allow, were focused on ones that would let generic classes and methods do things with generic types that they otherwise could not, rather than on preventing them from being used in nonsensical ways. That having been said, an...
Difference between “managed” and “unmanaged”
...
Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.
No free memory management or anything else the CLR provides.

How does one go about and try to find all subclasses of a given class (or all implementors of a given interface) in Java?

Cmake vs make sample codes?

Makefile by default builds a release target, but offers also a debug target:
#Makefile
CC = gcc
CPP = g++
RANLIB = ar rcs

Why can't we have static method in a (non-static) inner class?

Is there a printf converter to print in binary format?
..._PATTERN"\n",
BYTE_TO_BINARY(m>>8), BYTE_TO_BINARY(m));
You need all the extra quotes unfortunately. This approach has the efficiency risks of macros (don't pass a function as the argument to BYTE_TO_BINARY) but avoids the memory issues and multiple invocations of strcat in some of the oth...
What is the purpose of the '@' symbol in CSS?
...ructs. The @ syntax itself, though, as I mentioned, is not new.
These are all known in CSS as at-rules. They're special instructions for the browser, not directly related to styling of (X)HTML/XML elements in Web documents using rules and properties, although they do play important roles in control...
