I am working on an install program, for another program that will need a
list of printers on a system. Originally I found the printers by doing
this:
public PrintNames() {
String tName = "";
PrintService pServices = PrintServiceLookup.lookupPrintServices(null,
null);
System.out.println("Service count: "+pServices.length);
cPrinter = new String;

After many years of using LISP, I'm taking a class in Java and finding
the two roughly comparable in some ways and very different in other
ways. Each has a decent size library of useful utilities as a standard
portable part of the core language, the LISP package, and the java.lang
package, respectively. Both have big integers, although only LISP has
rationals as far as I can tell. Because CL supports keyword arguments,
it has a wider range...

Can anyone tell me what is wrong with the goto command. I noticed it is one

Hi,
is there something wrong with this code? It seems that it crashes
at the else { clause, when allocating a second record. Excuse for
the indentation, the g_warnings are from gtk.
Also, i'm using 2 pointers in the struct, which consists of 3 ints,
and 2 pointers, which i give 256 bytes each. Much to much ofcourse,
but it's just testcode.
The code doesn't even reach the g_warning in the { code.

I have the following code in a C# aspx page, but I keep getting the

I found the code for a program that is suppose to be able to work out
the sumation of i from 1 to a certain integer n.
however, when I implemented to code into Visual C++, it doesn't work.
The original sample code provided by the website:
unsigned int Sum (unsigned int n) {
unsigned int result = 0;
for (unsigned int i=1; i<=n; i++) {
result+=1;

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

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...
