Since the hope I express above is evidently in vain, it seems I should also have
pointed out that Tom's remarks were not accurate.
Yes, I erred horribly ... horribly. But anyone who cares to review the thread which
prompted Tom's aggression ("Re: Documenting character encoding --
comments/corrections?", on comp.infosystems.www.authoring.html) can see I was more
than ready to promptly correct any protocol breach that was brought to my
attention. In other words, Tom's goon tactics were wholly gratuitous.

"Massively," you say. Well. Congratulations for speaking your mind.
The irony is considerable. Tom Christiansen's own post in the above-mentioned
thread, sent around the same time he lobbed his clever grenade at me, uses a full
18 lines to promote the entry of hard RETURN's when composing messages.
(Incidentally, it does not make for fascinating reading.)
This is obviously on-topic for his supporters; others may wonder about their
Kool-Aid.
In passing, he misquotes a Netscape designer and offers a piercing criticism of the
Netscape interface ("totally fucked up").
Frankly, I find it unbelievable that anyone’s defending this guy. What kind of
place is the Internet?
But I think I may understand this passion about Netscape and Windows. It appears
there are still people surviving today who enter text into computers the way people
used to type on typewriters decades ago, monitoring their horizontal position and
hitting RETURN at regular intervals. The only way, some seem to think, to achieve
"writer-directed formatting."
Now, no one can deny (though this is not literally true) that both Netscape and
Windows are execrable, abominable products, embarrassments to mankind. But *at
least* some elementary concepts from the dawn of thinking have penetrated, and we
have autowrap. (Other features too, colors etc.; things that produce ire on
comp.infosystems.www.authoring.html aren't even remarked on ng's where people use
more modern apps.)
The greatest irony is that for all the protracted discussions of posting protocols,
html esoterica, bandwidth concerns, the record shows people talking at cross
purposes; misunderstanding simple English; failing, in short, to communicate.

Responsibility for what? Are you pissed off, miguel, that I called tom

Well, you're arrogant enough to believe that we're all going to
carefully examine the entrails of the previous discussion, most of which
has presumably no relevance to the point that you wanted to make, and

Thanx, but perhaps I should have said that the script is only run on an
extern server (I don't host it myself on my computer but on an professional
webspace provider). I use a proxy, but others who come from AOL or somewhere
don't use the same proxy as me, but my script always gives me the same IP,
that's why I thought it would be the IP of my webspace provider. I use it
for an IP check, so that hits are not counted more than once.

Using grep and a file sounds an inefficient way of doing this. Why not
use a hash? If you need persistence of the cache between runs, you
could use a tied hash.
Here's an example. This reads filenames on STDIN, one per line, and
calculates the MD5 signature of each file. The most recent 1000 signatures
are held in a tied hash. An array is used as a FIFO to decide which
signature to delete from the cache when it's full.
#!/usr/bin/perl -w
use strict;
use Digest::MD5;
use DB_File;
use Fcntl;
my $max = 1000; # Max number of MD5 signatures to keep
my %sigs; # Hash to hold MD5 signatures
my $sig_db = 'sigs'; # DB file in which to record MD5 signatures
# Tie the hash to the DB file, creating if necessary
tie(%sigs, 'DB_File', $sig_db,
O_CREAT | O_RDWR, # open r/w, create if doesn't exist
0640,
$DB_HASH)
or die "Error tying hash to $sig_db: $!";
# Get initial list of known signatures. This is used to decide which to
# drop when the cache is full. Note: when the program starts with an
# existing DB file, this list will *not* be in order of arrival
my @sigs = keys %sigs;
# $sig is the Digest::MD5 object used for calculating each file's signature
my $sig = Digest::MD5->new or die "Error creating MD5 object: $!";
# Loop, reading list of files
while (my $file = <STDIN>)
{
chomp $file;
unless (open(F, $file))
{
warn "Error opening $file: $!";
next;
}
# Calculate file's signature
binmode(F);
$sig->reset;
$sig->addfile(*F);
my $this_sig = $sig->hexdigest;
close(F);
# Is this signature in our cache?
print "$file: signature is ";
if (exists $sigs{$this_sig})
{
print "in the cache\n";
}
else
{
print "not in the cache\n";
# Add signature to cache
$sigs{$this_sig}++;
push(@sigs, $this_sig);
# Drop oldest signature if cache full
delete $sigs{shift @sigs} if @sigs > $max;
}
}
# Finished
untie %sigs;
__END__
Some alternatives:
1. Lose the tied hash. Keep the signatures in a text file as before.
Read them into the hash at startup and rewrite the file at exit, but
leave the file alone during the run.
2. If, for some reason, you must have a text file holding the signatures,
and it must be kept up to date during a run, you could use the fact that
the signatures are always the same length by opening the flat signature
file with +< and using seek to set the file position before updating it:
the position of the nth signature is (($n - 1) % 1000) * 33. You'd
need to maintain an external record of the position of the current 'first'
signature, since this would cycle through the file.

The de facto internet standards, the RFCs, have been written in plain

I can read RFC 1, dated 7 April 1969 without any problems; I don't

And in another 30 years, I will still be able to read the same RFC.
Without any problems. Without needing any special software.
The RFCs are published in plain text for damn good reasons. And they
communicate effectively - otherwise, you would not be reading this.
It's unlikely the IETF will change to non-plain-text format anytime soon.
And that's a very good thing.
Now, it might be true that www.mtv.com attracts more visitors and gets
more "hits" than a site that makes RFCs available. But who the fuck cares?

Well, I disagree. You didn't include my site
(http://www.plover.com/~mjd/perl/) in your list, but I think you would
have if you had known about it. Pages are black text on a white
background. I don't want to include a lot of graphic crap that will
make it less useful. I want my pages to come up as fast as possible.
I want them to be easy to read when they get there.
I don't want to use a lot of frames and tables that will slow down the
loading time and take up valuable screen space. I want people to be
able to start reading immediately and not to have to wait until the
entire page has loaded before any text appears. I want blind people
to be able to use my site.
When you say `the appeal of the web is' you are expressing your opinion.
Other people have a different opinion. That does not mean that they
are having `difficulties'.

perldoc File::Find to make it easy to recurse the directory tree.
Check errors and don't forget to write $! on error conditions, too.
And you can use '/' for path separator even in DOS.

my apologies for wasting your time Malcolm .. my original ('working')
test script has long since been written over .. so I can only guess that
in my haste I originally made the same mistake that the Cookbook authors
probably did .. ie. didn't use '-w' in the running of my script
without the '-w' all I saw was the successful mail arriving in my
mailbox and thought that it had worked .. now - with the warnings on I'm
seeing the same error as you regarding the "Odd number of elements"
your comments regarding the SMTP listener put my own mind to rest
because in your previous posting - when you asked about Mail::Mailer
versions - I took a glance at smtp.pm and was struggling to understand
how the "wrong" syntax was working .. back on the straight and narrow
now though

I work with it more; I don't recall having seen many stories.

I think it happens less easily in Python than in C (Perl did right in
my opinion to require { and } around all blocks). To me these problems
seem to be at least easily avoided, but this may be because I'm spoiled
my the wonderful python-mode that's supplied for Emacs, that knows
all about indenting.

[snip discussion on how this doesn't occur with braces in Perl]
Yes, this can be a slight annoyance with Python. Of course the parser
catches it so it not a cause for bugs, but still a slight annoyance. Not
a very large one though in my humble opinion, but I think I've been bitten
by it once or twice.

I thought of doing that, but I liked the single-sub version better,
because that way you don't have two separate closures that operate on
the same thing.
TMTOWTDI, of course.

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" from
almanac@ruby.oce.orst.edu. The real FAQ, as it appeared last in the
newsgroup, can be retrieved with the request "send perl-users FAQ" from
almanac@ruby.oce.orst.edu. 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" from
almanac@ruby.oce.orst.edu.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
