How can I cast from (long double*) to (const double*)
I have tried:
const double* Value1 = (const double*)Value2;
The compiler does not complain but the actual results when I access
the const double* are incorrect.
Note that the (long double*) is a pointer to an array of long doubles.

I have a string with format "0|first_name|last_name|..." which i can
split to a vector<stringby the "|" token.
At the moment to get the row number I'm using size_t row_number =
atoi(buf_string.s_scr()) which throws warnings.
What is the correct way to convert a string "2" to size_t 2?
Thanks in advance.

I'm having a very strange problem I can't seem to figure out and am hoping
maybe somebody has seen it before.
I get an exception "Cast string to date is invalid" with this chunk of code:

thing. This is were the exception occurs:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

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 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...
