Boolean method naming readability
... think were missed by several other answers here
It depends if this is a C++ class method or a C function. If this is a method then it will likely be called if (user.exists()) { ... } or if (user.isExisting()) { ... }
not if (user_exists(&user)) .
This is the reason behind coding standards tha...

Are inline virtual functions really a non-sense?
...
Virtual functions can be inlined sometimes. An excerpt from the excellent C++ faq:
"The only time an inline virtual call
can be inlined is when the compiler
knows the "exact class" of the object
which is the target of the virtual
function call. This can happen only
when the compiler h...
Static member initialization in a class template
...
Since C++17, you can now declare the static member to be inline, which will define the variable in the class definition:
template <typename T>
struct S
{
...
static inline double something_relevant = 1.5;
};

Hidden Features of PHP? [closed]
...lled on var_export()
public static function __set_state($array);
}
A C++ developer here might notice, that PHP allows overloading some operators, e.g. () or (string). Actually PHP allows overloading even more, for example the [] operator (ArrayAccess), the foreach language construct (Iterator ...
How do I pass multiple parameters into a function in PowerShell?

What __init__ and self do on Python?
...ss. The self parameter refers to the instance of the object (like this in C++).
class Point:
def __init__(self, x, y):
self._x = x
self._y = y
The __init__ method gets called when memory for the object is allocated:
x = Point(1,2)
It is important to use the self parameter ...
Should I compile with /MD or /MT?
...it will cause the application to link with the static multithread Standard C++ Library (libcpmt.lib) instead of the dynamic version (msvcprt.lib) while still dynamically linking to the main CRT via msvcrt.lib.
So if I am interpreting it correctly then /MT links statically and /MD links dynamically....
Detecting programming language from a snippet
... but when a file extension matches multiple candidates (e.g. ".h" --> C,C++,ObjC), it will tokenize the input code sample and classify against a pre-trained set of data. The Github version can be forced to scan the code always without looking at the extension too.

Addition: C++ templates are essentially cut-and-paste at compile time with the correct values substituted. In C# the actual generic template (not an "instantiation" of it) exists after compilation and thus must (pardon the pun) be gene...
