Hi All,
I have a class that creates a thread, a mutex and a condition variable
in its constructor. I am writing a copy constructor for this class in
C++. I am doing a simple copy using the member initialization list.
First of all, does anyone have any opinion about whether this will work
fine. I think it will. I believe a copy constructor, when using a
member initialization list, does a memory copy of the object's members
to be copied....

The design philosophy behind the boost Lock concept seems to be to
implement short-lived, tightly-scoped locks which automatically unlock
the mutex when they go out of scope. This design is nice because it
clears up all the pthread_mutex_lock/unlock clutter you find in code
that needs to unlock a mutex before leaving scope.
However, I find that sometimes you need to keep a mutex locked even
after the program proceeds beyond the current...

Hi.
I have a C# program that fires an external VB6 program which writes to
a file and terminates.
It is ugly, but this is how I have to do it. I cannot change this part
of the program.
The problem I am encountering is that the former process created by
this EXE is not complete
(it runs for a few seconds) when the next one wants to start. A

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...
