Hello, Perl world. This is the post-American-Thanksgiving issue of the
biweekly Perl newsletter, written just before American Thanksgiving.
There's not a lot to report this week, but here is what there is.
* Perl News
Perl 5.8.x pumpking Nicholas Clark revealed privately that a "u" had crept
incorrectly into his first name in the previous summary. There's no word
where it's escaped to now. If you've tried to send presents to Nick for
his hard work on releasing several stable versions of Perl in a timely
fashion, please make sure that you leave out spurious values.
In other news, the DBI has turned ten years old:
http://use.perl.org/article.pl?sid=04/11/17/1756239&tid=5
In the land of the CPAN, two important modules have had recent releases.
Itinerant coder Michael Schwern has resurfaced to release Test::Simple
0.51:
http://search.cpan.org/~mschwern/Test-Simple-0.51/
and ExtUtils::MakeMaker 6.22:
http://search.cpan.org/~mschwern/ExtUtils-MakeMaker-6.22/
These are highly important modules for building and testing Perl,
especially the core features, so developers, please test them with your
software and file bug reports if necessary.
* Perl.com Articles
Web Services haven't quite lived up to their hype (and RSS/Atom might save
us anyway), but there are still cases where client-server applications are
useful. Instead of building your own server, why not build atop Apache
httpd? Instead of building your own protocol, consider using Michael W.
Collins' mod_perlservice, an Apache module to make Perl server functions
available to clients written in a variety of languages. Client libraries
exist for C, Perl, and Flash already. Read more in "Cross-Language
Remoting with mod_perlservice":
http://www.perl.com/pub/a/2004/11/18/mod_perlservice.html
Maybe you have some free time over the upcoming holidays to polish that
module or program you've intended to finish. You'll likely spend a couple
of hours tracking down one last bug. Why not make your life easier and
pick up some practical skills with the debugger? The Perl Debugger Quick
Reference card, excerpted from Richard Foley's "Perl Debugger Pocket
Reference" is a printable refresher on some of the syntax you've read once
in perldebtut and never thought of again. Think of it as a present:
http://www.perl.com/pub/a/2004/11/24/debugger_ref.html
Finally, as usual, summarizer Matt Fowles covers the first weeks of
November in his Perl 6 Summary:
http://www.perl.com/pub/a/2004/11/p6pdigest/20041115.html
We'll be on a weekly schedule from here on out.
* Conclusion
That's all for this newsletter. Come back soon to learn how to write a
3D
engine in Perl.
Nope, not kidding,

*** Featured Articles ***
Perl Debugger Quick Reference
Perl's debugger is both powerful and somewhat esoteric. This printable
excerpt from Richard Foley's Perl Debugger Pocket Reference can help take
some of the mystery out of the common commands and put more advanced
features within your reach.
http://www.perl.com/pub/a/2004/11/24/debugger_ref.html
***
Cross-Language Remoting with mod_perlservice
Remoting -- sharing data between server and client processes -- is
powerful, but writing your own protocols is tedious and difficult. XML-RPC
is too simple and SOAP and CORBA are too complex. Isn't there something in
the middle, something easier to set up and use? Michael W. Collins
introduces mod_perlservice, an Apache httpd module that provides remote
services to C, Perl, or Flash clients.

This Week in Perl 6, November 9 - 15 2004
Matt Fowles summarizes the Perl 6 mailing lists, with the Parrot list
discussing continuations and the unchanging calling conventions, the Perl
6 folks discussing exports, and the Perl 6 Compiler list still strangely
quiet.
http://www.perl.com/pub/a/2004/11/p6pdigest/20041115.html

Implementing Flood Control
If the load of application relies on incoming events, you may eventually
face the happy curse of popularity: too much work to do with your
available resources. If you set a limit on how many events you can process
within a time period, you can avoid the flood. Vladi
Belperchinov-Shabanski explains the algorithm and demonstrates working
code.
http://www.perl.com/pub/a/2004/11/11/floodcontrol.html

This Week in Perl 6, November 2 - 8 2004
Matt Fowles summarizes the Perl 6 mailing lists, with the Parrot folks
talking about optimizations not to apply yet, the Perl 6 people receiving
updated Synopses and Apocalypses, and the Perl 6 Internals team being
strangely quiet.

Komodo 3.0 Review
ActiveState has recently released version 3.0 of its Komodo IDE,
supporting agile languages. Jason Purdy reviews the progress made since
the 2.0 release.
