Hiya,
I'm setting up some code in the spirit of Design Patterns, OOP, etc. All
nice and well, it handles pretty much all OO style things and serves my
purposes well. There's one last final question remaining: How to properly,
simple and eleganty implement functions. The functions are encapsulated in
the objects, the objects themselves are stored in a binary tree and objects
contain 'methods' (functions) along with data. I don't want to...

I've noticed that when constructing a subclass, the base class get's
it's contructors called.
Is there some way to avoid this? The base class has one variable, which
gets initialised to 0.
The subclass's constructor sets this variable to a real value.
So first the variable is set to 0, the variable is never used before it
once again gets set to a real value. It's a waste. Any ideas anyone?

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...

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...
