How do you create a static class in C++?

{
// I CAN'T access Foo::myGlobal !!!
}
At first sight, the fact the free function barC can't access Foo::myGlobal seems a good thing from an encapsulation viewpoint... It's cool because someone looking at the HPP won't be able (unless resorting to sabotage) to access Foo::myGlobal.
But if yo...
Turn a simple socket into an SSL socket

{
ERR_free_strings();
EVP_cleanup();
}
void ShutdownSSL()
{
SSL_shutdown(cSSL);
SSL_free(cSSL);
}
Now for the bulk of the functionality. You may want to add a while loop on connections.

Foreach loop, determine which is the last iteration of the loop
... this:
var elements = new[] { "A", "B", "C" };
elements.ForEach((element, info) => {

Console.WriteLine(element);
} else {
Console.WriteLine("Last one: " + element);
}
});
The extension method looks like this (as an added bonus, it will also tell ...
Android: AsyncTask vs Service
...o away, Android thinks, "Oh, now is a good time to kill this app, so I can free up resources".)
Also, depending on the last return value from Service.onCreate(), Android can attempt to "revive" apps/services that were killed due to resource pressure [ref].
AsyncTasks don't do any of that. It doesn...

What's the difference between git clone --mirror and git clone --bare
...ror option does not copy hooks, the config file, the description file, the info/exclude file, and at least in my test case a few refs (which I don't understand.) I would not call it a "functionally identical copy, interchangeable with the original."

What is the difference between application server and web server?

The information traveling back and forth between the server and its client is not restricted to simple display markup, but to interaction between the two.
In most cases, the server creates this interaction through a component API...
When is TCP option SO_LINGER (0) required?

What happens to a declared, uninitialized variable in C? Does it have a value?
... behavior.
void foo() {
int x;
printf("%d", x); // the compiler is free to crash here

In practice, they tend to just have some nonsensical value in there initially - some compilers may even put in specific, fixed values to make it obvious when looking in a debugger - but strictly speaking...
