This is Simon Cozens, managing editor of www.perl.com, here to
bring you the week's news and developments both in the Perl world
and on our own site.
* Perl at large.
Some very important news this week! The Perl Foundation has
announced its fundraising drive for next year. Through donations
from various generous companies and individuals, we managed to
sponsor Damian Conway to work on Perl for the whole of this year,
and this time around we're looking to sponsor both Damian and
Dan Sugalski, the internals designer for Perl 6. "The Foundation
is beginning drives for two Perl Development Grants, for Dan
Sugalski and Damian Conway, totalling $175,000 ($60,000 each
for stipend, $20,000 each for travel, and $15,000 for
Take this to your boss, your boss's boss, your bank manager, and
anyone else who you think will possibly give money to advance
the Perl cause. If you don't see why this is a good thing, check
out what Damian's been up to.
Oh, and talking of Damian, if you want *more* information about
what he's up to, there's an excellent interview with him on
pair.com's "Insider" newsletter:
As promised, Parrot 0.0.3 was released on Sunday, with the official
announcement going out to the world yesterday. This release is
particularly significant because it's the first one to have custom,
pluggable data types. Now you can create, for instance, Perl
strings, and have them magically numify to Perl number types on

More bioinformatics stuff! If you've ever used CGI.pm, GD, or read
Network Programming with Perl, you'll have heard of Lincoln Stein.
But what you might not have known about him is that he's a
bioinformaticist on the Human Genome Project, and has made some
interesting advancements in Perl's utility for bioinformatics.
We're highlighting an O'Reilly Network interview with Lincoln,
where he talks about what he's been doing with Perl and genomics:
Bryan Warnock is back, with another Perl 6 summary. He covers the
0.0.3 release, the newly-established Parrot FAQ, questions about
the use of the GCC register transfer language, and much, much more...
Steven Lidie, author of the forthcoming "Mastering Perl/Tk"
provides an inside look into one of the things he'd not managed
to get into the book - programming drag-and-drop services in
Perl/Tk. This week's article explains how to create an application
which can drag and drop objects from one Tk widget onto another.
