This books tend to teach programming (the syntax of a programm language), not

Do you ever join your threads?
Which Perl-Version do you use?
Try update to the latest. Threads had memoryleaks and might

Hi there!
I have a string "bbbababbaaassass". I want to get a string without any
double a 'aa' or and without the 'b's.
but if I do:

$s=~ s/aa|b//g;
as a result I will get a string "aaassass".
(I understand WHY I get this result.

is there an easy why to determit from which package/modul a function/methode is

Hey, If you are "looking" for a not so hard but very interessting project,

It will wait. This behaviour is called "blocking".
If you want to just start it and the go on in your code "non-blocking"
or If you want to do some tasks "at the same time", you should take a look at
fork, threads or easier Proc::ParallelLoop.
But If the bottleneck is your computingpower, this wi
There are some moduls I use under linux.
Problem is that Cisco CLI may change prompt.
Checkout Net::SSH and Perl Expect. (Also there is a Modul called
Net::SSH::Expect,
which I had not tried yet.)
You may need to install Cygwin. This gives you a lot of linux utils.
HaveFun,

I just wanted to ask if somebody has implementet an "nonblocking" socket reader,

The last time I considered using eval is years ago.

Hi there,
in the early days of the dbi-modul there was a function $dbh->ping().
nearly no driver ever implemented it.
I want to check the status of my db, in my daemon on a regular base.
I could not find any standard solution. Today I´m just doing a query
and check then if there where errors.
don´t like writing input checks for every methode, too^^)
Hope to see c++/java like polymorphism some day in perl.

Try unbuffer IO, this might be on off the Problem.

Ok, that was easier then I had expected.
The undocumented methode $sock->peerhost() will return the "human readable"
ip-address of the current datagram.

Hi there,
I got a question regarding IO::Socket. I am using IO::Socket to receive UPD
datagrams from a number of hosts. It works fine, but I can´t figure out how to
tell which host (and from which port) the datagram was send. I don´t want to
change the packet data. Here is a code snipplet of wh

There are some modul with many common regex to steal from or just import.
