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:

Hi.
Can anyone refer me to any articles about the compatibility between
c++ polymorphism and real-time programming?
I'm currently on a real-time c++ project, and we're having a
discussion about whether we should allow polymorphism. Our system is
not embedded and does not need to be as real-time as, say, a
pacemaker. But it does involve updating displays based on radar
input. So a need for something close to real-time is desired...

Hi, I understand the concept/definition of polymorphism. But what does the
term "runtime polymorphism" mean? I was asked to define it during a
technical interview. I gave a guy vanilla definition of polymorphism, but he
insisted on runtime. Did I miss a new buzzword while I was sick with the flu
last week or something like that?

Hello all!
Perhaps the most important feature of dynamic polymorphism is
ability to handle heterogeneous collections of objects.
("C++ Templates: The Complete Guide" by David Vandevoorde
and Nicolai M. Josuttis. Chapter 14.)
How to implement analogue of this technique via static polymorphism?
Perhaps there is special design pattern for this purpose...

I have to write a paper about object oriented programming and I'm doing
some reading to make sure I understand it. In a book I'm reading,
however, polymorphism is defined as:
"the ability of two different objects to respond to the same request
message in their own unique way"
I thought that it was:

Hi all,
I need a small clarification reg. Templates and
Polymorphism. I believe templates is really a good feature, which can
be used to implement generic functions and classes. But i doubt whether
it should not be used in certain cases.
Consider the case when all the params to a template
function/class are similar. My questions is that whatever can be
acheived by a template in such a case, can be acheived by runtime
polymorphism....

I've been programming in C++ for a little over 2 years, and I still
find myself wondering when I should use polymorphism.
Some people claim that polymorphism is such an integral part of C++,
that anybody who doesn't use it might as well just program in plain
C. I totally disagree with this, because I think C++ has a lot of
great features apart from polymorphism, such as the ability to
organize code into classes, code reuse through...

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.
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...
