I have a class called 'PrimaryKey' that represents the primary key of a
table.
PrimaryKeys can only be created and the class only implements .ToString().
The PrimaryKey class internally stores the data as either a int or a Guid
depending on the structure of the database.
If we simply used int to represent a primary key, rather than this
PrimaryKey class then programmers could do things like performing
mathematically operations on the...

Hi everyone,
I'm writing a webservice where I'm trying to expose a framework that
contains a number of classes which have read-only properties. I want to
expose data-transfer proxies of these objects with both getters and setters
and so that all the properties are exposed via the webservice and want to
copy all the data to the proxy before sending the data and only copy the data
from the proxy where the underlying object's property...

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,...

I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
