I think I've finally found a tutorial that can get me started:
http://www.zib.de/Visual/people/mueller/Course/Tutorial/tutorial.html
and I've been lurking for awhile as well. What happened is, I've
been playing with Qt in KDE on a Slackware 10.0 system, and following
their cookbook exercises, and everything's working, and I have no
clue what the code is doing, i.e.. how do I connect my brain to the

I'm having trouble finding out how to find the current PGconn

didn't give this up. Could anyone suggest where to look? I didn't even
see anything similar to this in the SPI_* documentation. Perhaps I am
totally mislead here?
Why:

Thanks your reply.
The article I read is from
www.hakin9.org/en/attachments/stackoverflow_en.pdf.
And you're right. I don't know it very clearly. And that's why I want
to understand it; for it's useful to help me to solve some basic
problem which I may not perceive before.
I appreciate your help,
sincerely.

Hello,
A couple days ago my friend (OOP guy) shows me what OOP was all about
in C++. This morning I figured I can do pretty much the same thing
with C (by putting function pointers in structures and using Macros).
I've gone pretty far but I'm running into problems because the function
pointers within the structures need an extra argument (a pointer to
that type of structure) so they know which data to operate on. Also, I
have to...

Hi, I'm using the following code to retrieve data from an xml file and
populate a javascript array. The data is then displayed in html table
form. I would like to then be able to sort by each column. Once the
array elements are split, what is the best way to sort them? Thank you.

I have been writing games and I also read about good programming
techniques. I tend to create large objects that do lots of things. A
good example I have is a unit object. The object controls and holds
everything a unit in my game is supposed to do. What are some some
cures for this kind of large object or are they OK because they
represent one thing. If not what are better ways to design objects
that behave the same way. Would it be...

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...

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...
