2/16    Perl Question: Under perl5 does local() do anything or do you have
        to use my()?
        \_ "When in doubt, use my. When not in doubt, think twice, and
            then use my." local() has very limited applications and can
            almost always be replaced by my.
                \_ Certain variables cannot be my'd. Basically, think of
                   local as "assigning a temporary value", and my as
                   "creating a private variable." See perlsub, like the
                   poster below suggests. -brg
        \_ Use local for dynamic scope, my for lexical.
           \_ And use perlsub(1) for a detailed explanation of exactly
              what this means.
                   \_ Thanks this had the explanation I needed. Basically,
                      in perl5 I need my() whereever I used to use local().
                \_ Go back to CS 60a/61a if you don't know what this means.
                   Do not pass 164, do not collect diploma.
        \_ Go read http://www.cpan.org you idiot.
           \_ This is a language issue, moron.  CPAN distributes packages.
              \_ Yes, RTFM before wasting people's time.  CPAN has, among
                 other things, the entire perl manpage in convenient
                 html form.  Idiot.
                 \_ THE MOTD IS FOR PEOPLE WHO WANT TO WASTE TIME.  DUH.
                 \_ It's only a waste of a person's time if that person
                    chooses to respond. And even then, that person may not
                    find it a waste. How much time did you waste to respond
                    anyway?
                    \_ You must be a fellow tweaker.  --tweaker
                       \_ I admit it. I tweak a lot.

3/4     Does anybody have some code or know of a program that will take a
        network/mask and return the list of address in that CIDR block?
        e.g. "iplist 10.10.10.0/24" and return 10.10.10.0 ... 10.10.10.255
        [I have a way to do this, but it involves distributing a large
        amount of code, which is kind of a hassle. Looking for something
        lightweight and either standard or easdy to rpm/port/yum install.]

        authenticate to a web page protected by a login form ('post'
        method to send username/pass, and cookies.)  Cookies don't seem
        to be the problem, with --save-cookies and --keep-session-cookies
        but getting the username/password submitted isn't doing it.  On
        this particular page, getting to a link, let's say 'example.aspx',

        upgrading Perl, DBI 1.48, & DBD 3.0002_1 I'm seeing something
        really weird. The following used to work:

8/31    Looking for an XML parser for Perl, preferably one that
        doesn't require installation (something already built in).
        If it's not already built in, I prefer something that doesn't
        require C compilation, and that I can just stick the *.pm
        to use. I'm looking for portability, not performance. Thanks.

4/10    In perl, how do I get time precise to the milisecond? The CPAN module
        requires recompilation and root access to install it, I'm looking for
        something more portable. Thanks!
        \_ If you need to know the time, there's no portable way to do it
           without modules.  However, if you just want a sub-second delay,
           you can do it with select -- for example, select "", "", "", 0.1;
