Folks,
I've asked this before but never got any response but its important and I
thought I'd pitch it again (hopefully a bit clearer)...
One can pass data from one function to another either by passing a copy, or
passing by reference.
My understanding of passing by reference (putting the & before a variable
during the function declaration) means that the original data is used.

I'm still trying to fully understand how best to pass variables between
pages/usercontrols/each other.
On a current site I've done, I've had one userControl do the logic and set
the variable, and then I had other usercontrols simply read this by
traversing the class structure: siteClass.userControlClass.specficVariable.
That worked fine.
The new site I'm working on is a bit different, as I'm using multiple

Hi,
I noticed in Python all function parameters seem to be passed by
reference. This means that when I modify the value of a variable of a
function, the value of the variable externally from the function is
also modified.
Sometimes I wish to work with "copies", in that when I pass in an
integer variable into a function, I want the function to be modifying
a COPY, not the reference. Is this possible?

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

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 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...
