Hello,
I have a table which has a foreign key relationship with itself. I
want and expect my updates to cascade (deletes definitely cascade as
expected) but instead I just get error 1217: foriegn key error.
I have written example code to use in reproducing the problem:

We're in the middle of upgrading from MySQL 3.23 to MySQL4.1.
I'm trying to import all of the info in the mysql database (ya know the
db that keeps track of all the users and what they can and cannot do).
I tried just a standard mysqldump from the old box. Copy the file over
to the new box. And do a mysql -uroot -p < /tmp/mysqldb.sql. Lo and
behold it doesn't work. Looks like there are more columns in some of
the tables.
Is there...

Hello PHP programmers.
I had a brilliant idea on one of my pages that selects some data from
my mysql database.
I first set the page up to display some info and an image, just one
item, with a row of data, etc.
then I thought it would be nice to do a select, and perhaps an update
(the title of the image) on the same page.

I want to add functionality to my site that will enable me to eMail users every time I post a new page or do a significant update.
I guess I will need a mechanism to enable my users to register and then some code somewhere that I can run to send my registered users a link to the new item.
My ISP gives me a MySql database where I guess I will have to store my registered users' info.
Can anyone point me at the code I neeed to do this?
I've...

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...
