Source code shows that NSA uses Tor server as the target For the first time, German public television station ARD disclosed source code snippets of the NSA Monitoring System XKeyscore to the world.

I encountered a small problem when I used the object meta class in combination with the namespace today. Let's summarize it. This scenario: A is a connection class and B is a client class. Different namespaces are defined in different header files, A wants B to be able to access its own private members, so B is set as its friend Meta class, Class B needs class A objects for initialization during instantiation (constructors use Class A object pointers ). This involves the mutual inclusion of hea
