Production use of Jakarta's Tomcat.
First, some brief background.
My company have a servlet application that connects to a MySQL
database.

tomcat servers is via DNS round robin load balancing).
The database is on a another win2k server.

I'm a Java Web developer NEWBIE that has inherited a website that
fails every 2 hours due to poor connection pooling between Tomcat
4.0.6 and mySQL. In efforts to resolve this problem, I've created
another replica DEVELOPMENT website and upgraded it to Tomcat 4.1.27.

Hi guys,
We have a problem with Dual AMD64 Opteron/MySQL 4.0.18/Mandrake 10
for a very high volume site. We are evaluating the performance on our
new server AMD64 and it seems it's slow compared to Dual Xeon/MySQL
4.0.15/RedHat8 and Dual Xeon/MySQL 4.0.18/Mandrake 10.
And it seems there are zombie threads. 570 threads in 1 hour and we
didn't even use JDBC connection pooling at all. These threads are
supposed to be gone within 60...

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.

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,...
