It would have been awesome if they treated him to some Tandoori chicken.
Anyway, congrats on the award. Hopefully they showed you a few tricks to
get around some of the nuisances these latest "improvements" gave us?

Congratulations! Perhaps you could use your new clout to get the eBay
development team to improve their configuration management and change
control procedures.
That way we'd have fewer broken, untested web functions to deal with.

Subject: memory efficiency - for loop with reverse list
Message-Id: <1150032522.472561.176700@h76g2000cwa.googlegroups.com>
I am reading Damian Conways "Perl Best Practices", in chapter 8
(Built-in Functions), paragraph "reversing lists", he discusses coding
a down-iterating for loop:
I quote from the book
===========================
>> instead of writing:
>> for (my $remaining=$MAX; $remaining>=$MIN; $remaining--) {
...
>> write:
>> for my $remaining (reverse $MIN..$MAX) {
...
===========================
I understand the benefits of the second loop and Damian states that the
difference in iteration speed is usually not even noticable.
But I can't find any statement about memory efficiency, so my question
is this:
In the second for-loop (the one with the reverse-function):
would the entire list ($MIN..$MAX) be constructed first, then reversed
and iterated over ?
...or...
is there some optimizer which internally would translate the for-loop
into a memory efficient for (my $remaining=$MAX; $remaining>=$MIN;
$remaining--) ?

Sorry for this question but how do I write a simple "Hello world" HTML page from a
perl script?
In other words if I click in an already existing html page on a link like:
...
<a href="/export/home/aaa/cgi-bin/writehello.pl" target="_top">Click on this link</A>
...
a html page with the following stuff should be written and displayed in the browser:
<HTML>
<HEAD>
<TITLE>Test</TITLE>
</HEAD>
<BODY>
Hello World
</BODY>
</HTML>
How should the perl script look like ?
Do I have to change the perl script if I use the domain name instead of the internal path name?
<a href="http://www.mydomain.com/cgi-bin/writehello.pl" target="_top">Click on this link</A>

First thing to note is that something has to execute the Perl script - and
your browser isn't going to do that.
You need to run a webserver and then have the webserver run the script via
CGI (or FastCGI, or Apache::Registry, etc).
It is also possible to write Apache Modules in Perl using mod_perl. The
approach taken for them is somewhat different, I'll leave you to google up
some resources if you want to take that route.
> How should the perl script look like ?
http://search.cpan.org/~lds/CGI.pm-3.20/CGI.pm has examples.
The basics are that the script should output some HTTP headers, at a minimum
the Content-Type header, followed by a blank line, followed by the
document.
Template-Toolkit is a decent choice for producing the actual content. Other
options exist, such as HTML::Template.

As I said earlier, you can't typically persuade a browser to execute a Perl
script on your filesystem. As far as through a webserver it concerned, it
makes no difference if a link to the resource is relative or absolute.

It's a good question, but why did you crosspost it to an HTML group too,
without mentioning that you had set followups?
Using CGI.pm, you would write
use CGI qw(:standard);
print start_html('Test'), p('Hello world'), end_html;
Unfortunately, CGI.pm generates XHTML markup by default. XHTML is not
suitable for use (as a distribution format) on the WWW now or in the next
few years. If you do just simple things, you might have your XHTML
interpreted as good old HTML, though.
CGI.pm might have some switch to generated HTML 4.01, but personally I
prefer just writing it myself so that I know what I get, as opposite to what
different versions of CGI.pm on the server might generate this week,

That would only be the proper URL reference if, beneath the HTTP-served
document root of your Web server, the CGI scripts were found in a
subdirectory "export/home/aaa/cgi-bin", which is not a common
situation. Perhaps that "/export/...." stuff is intended as the full
path from the root of your machine? That's not what would be used in a
URL, whether it be to a script or a static HTML document. More likely,
the correct URL relative to your server document root is
"/cgi-bin/writehello.pl".

This can be done lots of ways; one would be:
print qq~
<HTML>

<TITLE>Test</TITLE>

Hello World

</HTML>
~;
> Do I have to change the perl script if I use the domain name instead of the internal path name?
The script doesn't know or care what form of URL you used to access it.
The matter of whether you used a relative or absolute URL is known
only to the browser, as the server itself gets a request with a fully
qualified URL.

But that's because *you* know what you are doing. Most folks who try
to hand-code - instead of using an appropriate module - succeed in
getting something wrong in their HTTP and/or their HTML. Sometimes it
will be sufficiently wrong that the effects will be obvious, which is
OK and then they can fix it; but other times the effects are more
insidious, aren't evident to the programmer, and only come to light
when their script turns out to be an open gateway for spamming or
other forms of abuse, and their IP is already blacklisted at the
anti-abuse services.
Furthermore, if things change, or bugs are discovered, the module is
likely to get updated accordingly, and anyone who is tracking changes
will get the benefit of the improvements, without having to re-design
their hand-knitted code.
CGI.pm is not without problems, but I would not choose to recommend
hand-coding to someone whose level of expertise is not known (well,
other than for tutorial or experimental reasons).

But of course, as I forgot to note, this must be preceded by sending an
appropriate content-type header:
print "Content-type: text/html; charset=iso-8859-1\n\n"
(end with an extra newline to show that the headers are finished and
the main content begins).
As others have noted, it might be better to use a standard library
module to generate the HTTP and/or HTML, though I'm one of the
curmudgeonly types who is more used to "rolling my own".

Well, your comment was challenged, and I offered a reasonable
interpretation of what you might have meant (which indicated a more
general point in any case, namely that libel law is not quite as simple
as the original poster was making it out to be). If you don't wish to
defend your position, that's fine, but pointing fingers is kind of weird
at this stage.

In the U.S, for instance, you wouldn't have to prove it. It would be
sufficent to demonstrate that there's enough evidence supporting it that you
weren't reckless in writing it.
