I'm new to python, so excuse me if i'm asking something dumb.
Does python provide a mechanism to implement virtual functions?
Can you please give a code snippet also...:)
Thanx in advance

Hello!
Assume you have the following interface and classes shown below.
It is said that a class must implement all the methods in the interface it
inherits.
Below we have class MyDerivedClass that inherits IMyInterface but
MyDerivedClass doesn't implement method DoSomething() it inherits it from
the base class MyBaseClass.
So the statement that a class must implement all method in an interface that

I have an interface class with maybe eight functions, defined in one
workspace and am defining a class in a second workspace that derives from
this interface.
Unfortunately only 7 of the 8 functions in my derived class compile whilst
just one of them refuses to be recognised, leading to an error message
"...does not implement interface member...".
Try as I might, I can't fix the error. I have cut and paste names so can
rule out simple...

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

Overview:
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.

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...
