download. At the en you klik on a link that says download and this url is
mapped to a servlet. The servlet looks up the pictures you selected and

Hey,
I would appriciate if anyone can help on this one:
I have a java object/inteface having a method with a boolean
parameter. As I'm trying to call this method from a javascript it
fails on a type mismatch.
It is positively because of the boolean(java primitive)parameter. It
goes fine if I change this parameter to int or String.
This inteface has a lot more methods which works fine, it is just the

First of all, I don't know much about Java, even its naming and version
numbering nomenclature, and second, if there is a better group to ask this
in, please let me know.
System is Mac with 10.4.4. I have Java 1.3.1 and 1.4.2 plug-ins, and J2SE
5.0 (1.5.0) installed. The Java preferences application lets me choose J2SE

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

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.

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...
