Hi Jonathan,
Argh, really stupid mistake by me. ) But let's use it to explain some
points a bit further, shall we?
A skilled craftsman knows his tools well, and Perl programmer (with CPAN as
THE collection of tools of all sizes and meanings) has an advantage here: even

Hi John, yes, good point! Totally forgot this. ) Adding new files to a
directory as you browse it is just not right, of course. Possible, but not
right. )
I'd solve this by using hash with filenames as keys and collected 'result'
strings (with md5 and filesizes) as values, filled by File::Find tar

Yes, I agree the code looks strange. Do you have any idea to do this
with a clear code? I mean to find two same letters, "p" in @a?

Hi Xi,
You're looking only for 'p' letters, not D and O? Why?
Anyway, generic solution will be something like...
my %seen;
my @repeated = grep { /some regex here/ && $seen{$_} > N } @source_array;
... where N is how many times the symbols should appear in the source array
to be counted as dupl
Oh my, of course it should be...
my @repeated = grep { /some regex here/ && ++$seen{$_} > N } @source_array;
... to work properly.

I'm not sure if this is the right list for this, so bear with me. If it
isn't I'll be glad to post it on the correct one.
I've got a problem with passing variables to a SQL server inside a CGI
script. My code is like this:
my $begin_time = "2011-11-16 11:00:00";
my $end_time = "2011-11-16 1
Hi all,
I've finally finished writing the 5th part of "Perl for Perl Newbies":

Hi Mark,
If your variables are strictly internal and by no means might be ever
tainted (read: user input), what you're doing is mostly ok.
But you need to quote the dates passed within query itself, like this:
my $sql = qq/SELECT * FROM `events` WHERE `date` BETWEEN '$begin_time' AND
'$end_time'/

If you pass into SQL query something assigned by user, use placeholders by
all means. ) It's not that hard, but it'll save you a lot of headaches,
believe me. )

I am confused what this variable does: $_
If someone could give an example or explanation of what this variable $_ does
in perl, that would be great!
Thanx.

$_ is the default variable, which gets assigned to and used in vario

Great work, Jonathan!
Notice how simple your script has become - and that's a good sign as well
in Perl. :) We can make it even simpler, however.
As you probably know, Perl has two fundamental types of collections: arrays
