Hi,
We are implementing some wrappers in C++ according to the Adapter
Pattern. The classes and their methods in the Adaptee classes
(open-source library) have already the interface that we like, but we
want to rename them so we want to implement the Adapter classes in
such a way that we only have to rename the Adaptee classes. We prefer
to use #define's because of the better run-time performance, in stead
of implementing wrapper...

Hello Everyone,
I am implementing a simple interface in C# using Visual Studio .net and was
quite surprised to discover that the C# compiler does NOT complain if a
method on the interface is not implemented.
VB.net on the other hand generates a compile error if a method is not
implemented. This helps in ensuring that all interface methods are
implemented.

In a typical class, do I need to indicate that it implements the IDisposable
interface and then create a Dispose method that implements the Dispose
required by the IDisposable interface or can I just make a Sub Dispose() and
the CLR will know that this is the Dispose method to call when the object
falls out of scope?
Thanks.

hi,
My question is:
1. To avoid possible memory leaks, when you use this pattern, after you
have dealth with the unmanaged resources and before you take your
object off the finalize queue, how are you sure that your managed
object resources are completely freed up of resources it's might be
using? In my case below I have a private bool variable. Are there any
other managed resource that you might need to explicitly free up in

Hello,
What is the purpose of implementing the Observer Pattern if we can trigger
an event easily?
For example (from books),
You have a "Forecaster" which notifies "Observable" when a prediction is
ready, then there is a "WeatherViewer" which calls methods from the
"Observer Interface".

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,...

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...

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...
