Add to @INC

You might need to add a path to @INC for Perl on some hosts:

BEGIN{push @INC, "/home/user/perl/usr/lib/perl5/site_perl/5.8.7";}

Favicons

The following will work under any modern browser (IE included):

<link rel="shortcut icon" href="/favicon.ico"
  type="image/vnd.microsoft.icon" />
<link rel="icon" href="/favicon.ico" type="image/vnd.microsoft.icon" />
  1. link must be inside head
  2. /favicon.ico is a legacy name and path that older browsers will sniff regardless of the above code
  3. type may be image/gif or image/png (but it doesn't work in IE)

Function arguments in Perl

a.k.a. URGHHH...

The three ways you want to remember are:

  1. If you don't know exactly what's coming, roll it all in a hash:

    sub perlFunc {
  my %args = @_;
  print $args{what_was_that_again};

  return(%args);
}

  2. Or, if you do know what's coming:

    sub otherPerlFunc {
  my ($what_was_that_again, $oh_yeah, $never_mind) = @_;
}

  3. And finally, if it's a single parameter you might as well just:

    sub oneMorePerlFunc {
  my $singleValue = shift;
}
