How to make such a socket?:)
I understood that there are 2 ways:
using IO::Socket
using Fcntl ?
I'm sort of familiar with IO::Socket, and I write simple IRC bots/servers. I thought that: 
$sock->autoflush(1);
$| = 1;

makes the socket non-blocking, but a friend of mine just laughed and said that I'm wrong :) He said that I better use Fcntl, but it still could be done with IO::Socket... I'm confused.
Let's say according to me, a non-blocking socket allows other parts of the code to be executed in the same time where the socket is being read or wrote. This is how I do with IO::Socket: 
IO::Socket -> create the socket
$sock->autoflush(1);
$| = 1;
while (<$sock> ){
if ($sock =~ /some stuff/){
do(some other stuff);
}
}

So in that way I make simple query-response bots, but nothing more than that.
I want to make simple application: a timer bot. Let's say at every 30 seconds, it writes a line to the socked, and uses time() function. I don't know even where from to start. Somebody give me a direction please?
