Hi,
I'm wondering how C++ .NET initializes class members. I have code that
looks aproximately like this:

// Factory object creates instances
_gc class Factory {

I am trying to create a way to register static members of a **class**, not
an object, for making an object factory. The main thing I want is to be
able to make a call like
class MyClass
{
public:
MyClass *factory();
};
register(MyClass);

Hi
I'd like to use metaclasses to dynamically generate a class based on a
parameter to the objects init function.
For example:
class MetaThing(type):
def __init__(cls, name, bases, dict, extra_information):
super(MetaThing, cls).__init__(name, bases, dict)

I come from a background of Java and C# where it is common practise to have
one class per file in the file/project structure. As I have understood it,
it is more common practice to have many classes in a Python module/file.
What is the motivation behind it, would it be a bad idea to have a guideline
in your project that promotes a one class per file structure (assuming most
of the programmers a background similar to mine)?

Hi
I found that a type/class are both a subclass and a instance of base
type "object".
It conflicts to my understanding that:
1.) a type/class object is created from class statement
2.) a instance is created by "calling" a class object.

I have a class that reads an XML and
according to its contents, it creates a
List<Letter>, where Letter is an abstract
class that is implemented in Alpha and
Beta classes.
I use a foreach statement consisting of a
switch upon which i create an instance of
e.g. Alpha an add it to the list.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
