I am new to Linux and trying to use some modules (even CGI.pm) and compile
them for the Apache server I am playing with (educational purposes).  I am
running Mandrivia 2006..
I am trying to compile a couple of modules and with both of them I get the

I'm writing a simple client-server application, and I'm trying to find a
way to tell if the other end of an open TCP connection has gone offline.
I heard that with C you can send a packet of data and check if an ACK
packet comes back. If it doesn't then the connection is closed. ...

Dear Sirs,
I want to convert a HoA into AoH. Basically what it does
is to create a distinct hash for each pair of array element that comes
from different keys (see the example below).

Not sure how much of a beginner question this is.  I've been searching
mail archives and can't find anything about it.  I've embarrassed myself
by giving advice based on my reading of the Camel book, but the advice
doesn't work.

I would like to execute a dir */s command in windows and save the output into an array. I know I can do this in perl by doing executing the following command in a perl script:

Dear Sirs,
I have the following problem.
I am trying to put the bracket in a string given the set of its substrings.

to knacker my filesystem.

I see where you can test for a match in a string of data using the If ( )
statement, but can you use it with an 'index' statement?
The data may look like this:
$DD = "5000|SIHHTEXT"

i want to search for a pattern in html text and replace only those
occurences that are not enclosed inside <> (html tag, not perl operator).
i was thinking of something like
$string =~ s/$pattern/test for <> or similar; else replace/ge;

When die is used, there is message something like:

I'm making a crude attempt to parse through some database BLOBS with
some success.  Some of the information is in XML format, some in
"text".  But a lot of crud exists because of the binary characters.
I originally tried this:

Does anyone know what happened to pdl.perl.org?  This is supposed to the
the home site of Perl PDL, a scientific programming and graphics-producing
add-on for Perl.  The website is defunct, and I am seeking an alternative
source of information.
