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

I am confused what this variable does: $_
If someone could give an example or explanation of what this variable $_ does

Hi Mark,
If your variables are strictly internal and by no means might be ever

But you need to quote the dates passed within query itself, like this:

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:

Hi all,
I've finally finished writing the 5th part of "Perl for Perl Newbies":

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
in this code what is the

Oh my, of course it should be...

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
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 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
