Hello,
Thought I read somewhere saying that there is a limit to how many
connections are available per mySQL account or something like that. Can
someone please clarify?
I wrote a PHP tool that uses a different PHP file whenever someone hit an
HTML form button (ie Submit). It turned out that each one of these PHP
files need to re-open the link to the mySQL database by the following
snippet or else that particular file won't work:

Hi,
I guess there is no way to limit COUNT(*). Is that right? We cannot use the
result of COUNT in WHERE condition or LIMIT doesn't help. In this case so
far I have retrieved a field and used LIMIT. Is there a better way to
control it?
Thanks

I am setting up a huge database in mysql, and I get the above error in
Linux. I believe it is related to the size of one of my tables, which
is 4,294,966,772 bytes in size. Can someone help. How can I break
that barrier.
A google search did not turn up anything useful.

Mysql is filling my /var partition because the log limit doesn't seem
to be respected.
I've tried many different settings in /etc/mysql/my.cnf but nothing
works.
Logrotate is not enabled/configured. I just want mysql to use a maximum
of, let's say, 1GB of my /var partition
The log is /var/log/mysql/

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

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...
