Google can't find me a good example of how to use the "if exists"
syntax in MySql. Is it right that to use it this way:
INSERT INTO IF EXISTS tMyTable VALUES("xxlk", "lkjlkjlkjljk")
I want to insert into a table but only if the table exists.
How does one, in general, from PHP, test for the existence of a table,
without getting an error message?

Is the following code correct for serializing a quasi-single class, that is
a class that has a descreet (though more than one, so not a true singleton)
number of static instances and no dynamically creatable instances? Please
forgive my use of terms. Quasi-signleton is a term I made up and static
instances is a little bogus too but I don't know the correct terms for what
I mean if there are any. However, I think the code below should be...

Hi,
I have a problem when I try to access a DLL I have created. Basically I have
an application which uses a number of custom DLLs, I needed to amend one of
the DLLs, so I removed the specific Reference from the application, amended
and rebuild the DLL and then added the reference back into the application.
There was no need to amend the applications code as this was a very minor
change.
When I run the application I get the following:

I'm flipping my wig here, people. I'm using classes and making each class a
file. when I'm including dependet classess, I use require_once to avoid
multiple declarations - yet they happen. I put debug_print_backtrace in the
file to see how it is included, and here's the output:

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
