hi all,
I'm a newbie Python programmer with a C++ brain inside. I have a
lightweight framework in which I design a base class and expect user to
extend. In other part of the framework, I heavily use the instance of
this base class (or its children class). How can I ensure the instance
IS-A base class instance, since Python is a fully dynamic typing
language?
I searched and found several different ways to do this:

Hello!
Private inheritance is sometimes called implementation inheritance.
If you use this private inheritance how is with the usage of overriding
then.
Is overriding used less often when having private inheritance then when you
have public inheritance.
I just want to have you opinion about this matter.

Hi,
Have this following hierarchy which am implementing for a networking
program. The base class 'ASocket' is the base class from which
'AListener' and 'ATalker' inherit . None of the functions in the
derived classes would override functions from the base class. The
derived classes would extend the base class. A couple of doubts :
1. Should the functions in the base class be declared virtual ?

Hi!
I am getting the following error message for my fairly simple web service. I
have classes and have two DataSets that reference the same classes. The error
is:
The XML element named 'GetCustNoResponse' from namespace 'http://mydomain/'
references a method and a type. Change the method's message name using
WebMethodAttribute or change the type's root element using the
XmlRootAttribute.

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...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

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...
