Since the localtime function is documented to return the year minus
1900 (which is not the same as the year modulo 100) it will return a
four digit year in 2900, as long as the people who make operating
systems and C libraries make an appropriate sized time_t.

Check out this URL, it talks about a script to ask yahoo to give it links. I
think it's pretty cool, and it was quite helpful for me to figure out how to do
such things.

From: Robert L. <email@in.the.sig>
Subject: group moderation -cgi script
Message-Id: <6i9lcg$j39@news-central.tiac.net>
Hi,
I'm looking for a cgi script that can be used to moderate a
news group or a mailing list through the www.
Here are my ideas on how this should work:
One of the moderators accesses a page that requiers a password.
The script reads a mailbox, checks the amount of mails, checks that
none of the messages exceed a certain size limit, takes the first five
messages from the mailbox and makes an html page out of them. Each of
the mails is separated by a bar, under each there is a form that
allows the moderator to add a comment, as well as chose from three
options: accept, reject (return to sender), forward to the next moderator
for a second opinion. No matter what option is chosen, the comment is
added to the mail. At the buttom of the page there is a send button.
When the moderator clicks on the button, the script processes the
form, adds text and appropriate headers when needed (in case the mail
was accepted), forwards emails to appropriate destinations, asks whether
the moderator would like to process the next five emails (should also
give a number of emails left).
The script should allow an unlimited amount of moderators, and keep
track of date, time, mails accepted and who processed them (just in
case someone keeps on screwing up and his access has to be revoked),
and have a different user name and password for each moderator.
Well, that's my ideal script, but of course anything that works would do.
:)
This would allow us to have an unlimited number of moderators. I know
there are already listservers that, using some kind of a round-robin
system, can do this also. There is a problem with those however,
mail has to sit in someone's box until that person is ready to process
it.
With moderation through www, the mail simply waits in a central place
for the next available moderator, is sent in the right order, and with
say...10 moderators wouldn't have to wait longer then aprox. 3 hours.
Has anyone seen anything like this? If not, could someone write this?
This is for non-profit use, and I would imagine a lot of groups/mailing
lists could use something like this (unless ofcourse there are better
solutions I'm not aware of.)
Thanks for any help,
Robert L.

Subject: how quickly can you unpack your shorts ?!
Message-Id: <Es86IJ.BFt@news.rbgkew.org.uk>
I'm trying to speed up some code that processes a large (50MB) binary file:
..open file etc...
for ($i=0,$i<1000;$i++){
$byte_count = read (IN, $buffer, 5000); # read a 5K chunk
push (@array, map (hex($_), unpack (("H2" x 5000), $buffer)));
....do things with array data....
@array = (); # clear the array
}
...close file etc....
most of the time in the loop is spent unpacking data. Can anyone suggest
something that would achieve the same thing but more quickly?
Currently takes about 3-4 mins.
thanks
Tony
p.s. I can't read the whole 50MB of data at one time because I don't have
enough memory.

Shouldn't do the following the same, but without the extra
map/hex loop?
push (@array, unpack ("C" x 5000, $buffer));
Or am I misunderstanding the pack/unpack templates?

But if the "<URL:" and the ">" is the jar, then why does Deja News
only use from the "<URL:" to the end of a line, breaking many of the
URLs I put in my text?
And why didn't they respond to my mail asking why their software
doesn't use the "Recommendations for URLs in Context" of RFC1738?
(I've had some suspicions on the answers. My links are broken, because
Deja News' software is broken. They didn't respond because they don't
care. If anyone else has some alternate theories, I'd be willing to
entertain them.)
Deja News' first suggestion was to make sure URLs stay on line line,
but that would make some lines containing URLs extend past 60-70
columns, which then would break Usenet conventions.

"Jason He" <jason@itrade.net> writes:
>does anyone know how to pass a hash from C to Perl ?
Depends on what you mean. Do you want to create a C function that
takes a hash and then have perl call it? If so, first you need to
learn how to write C extensions and then learn how perl represents a
hash. For that, you should look at the perlxstut, the perlxs, and the
perlguts man pages. Do you want to put perl inside of your C program
so that you can ask your C code to create a hash and then use it in
perl? If so, you'll still need the perlguts man page, but then also
look at perlembed.
Or do you want run the C program and the perl sript as two different
processes (maybe calling the other with system(), using perl's
backticks, or C's popen() or whatever.) then you need to convert the
hash into a format that can be read by the other. One simple form
would just be a text stream:
key: value
key2: value2
Another simple way would be to use DBM files. The text stream method
may be faster if you pass the information through a pipe rather than a
file, DBM files are inherently disk based. On the other hand, Perl's
module of handling DBM files looks a lot like its hash arrays, and the
C interface to DBM isn't bad either. (For more information on DBM
files see the tie function in the perlfunc man page and the perltie
man page.)

I am trying to find a particular patter in a document and it doesn't

What seems to be happening is that the serahc is getting mucked up with
carriage returns. This causes the search to fail. I've tried using the

creating a single line - and thus eliminating any carriage returns.
When I did this it worked like a charm.
I would very much appreciate any help on the situation. I have posted
some relevant code below. Pleazse excuse the primitive look.
$NewHRef = '<!--#include file="clindisc.mdssi"-->';
$LookFor1 = "<TABLE(.*?)Clinical Discussion(.*?)Submit Your

$buffer =~ s/$LookFor1/$NewHRef/ig;

But who cares? Your editor is the most important tool you use, and you
can sacrifice a few bytes of memory and a few MB of disk space for it.
I mean, it's *the* tool you use for development, and if you can't make
room for it, why bother programming? Your editor should be one
place where you never skimp.
Besides, I've always said Emacs is the most bloated vi clone

To me, the most basic and important difference between Perl and Java is
when you get Perl program and it doesn't work on your system, you can
hack the code and make it work. If a Java binary doesn't work, you're
just SOL and there's nothing you can do. At least Perl doesn't pretend
to work as-is on all platforms and gives you an out. Java assumes that
everything is fine and breaks down horribly when it is not, but Perl
assumes that it is in the real, Murphy's Law world and helps you out.
This is one reason why I've never been able to figure out the Perl ->
Java cross compiler thing. It seems like it is throwing away the best
aspects of Perl.

That's not necessarily true. I can hack the code on a Java app or
applet to make it work on my system just as easily as I can with Perl.
I think there is a large misconception about "Write Once Run
Anywhere". Just b/c the creators claim that, they know good and well
that there are always going to be exceptions. Hell I can code an app
in VB that runs great on one Win95 machine but the very next machine
may croak the very instant I invoke the application. Same for Java,
C, C++, or Perl.

If you think in terms of a scalar being a variable with zero dimensions
then the Perl usage makes sense. Whenever you want to specify a size
as well as a direction for something, then you need more than one
number, so zero dimensions of storage is not enough and you need an
array.

No, it uses the "right" port, where you have defined "right"
and "wrong" wrongly :-)
smtp is defined to be 25/tcp. If you use a different port,
you have to tell your code to use that port instead.
Of course, you can set up a local service called smtp on a
different port but that is probably asking for trouble. You
can tell the usual MTAs to use ports other than 25 for
outgoing mail (e.g. M mailer defs. in sendmail).

It's quite possible that there is no DNS A record - what
happens during the gethost* lookup depends on how your local
nameservice is implemented, and how you address your smtp
server box.

To handle all possible situations - everyone does it
differently :-)

Only if you are allowed to send mail to that server, or if
that server allows anyone to relay, which it shouldn't.

Depends on how you set it up. Presumably "yes" in the
default situation where you are a local user on the same
machine.

Subject: visual basic replacement
Message-Id: <35487AA8.25A0D13A@etsetb.upc.es>
I'm just doing little cgi with perl.
I know perl can be used in win32.
I wonder if I could make windows applications
in perl and get rid of visual basic.
I'm talking about database client applications
where the db could be in a server or access.
I know I can use DBI for access a db, what
I want to know if perl is suitable for building
typical windows stuff and if there are modules
for displaying forms and dialogs ...

I think that's what I mean when I say "Popularity ain't all it's cracked
up to be." AOL and the Internet in general, and I'm sure others can
furnish examples, did not fare too well be being "popular."

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
