June 2007 Archives

This is an easy one. I need a script to grab conference event data from the Perl community Google calendar. I've got it started, but it needs some polishing.

If you're interested, email me and I'll send you what I've got so far (cbrandt xatx perlfoundation xdotx org).

For a year or two now, I've hosted the Perl 6 and Parrot wikis on my home server, on a not-too-fast DSL line, at rakudo.org. They've now been moved to the wiki infrastructure at perlfoundation.org, on a dedicated box. This means much better performance, so if you've tried the wikis before and found them slow, check them out now.

The moved wiki workspaces are:

Thanks to Socialtext for the hosting.

The Pittsburgh Perl Workshop is a low-cost technical conference held at the University Center on Carnegie Mellon University's Oakland Campus. The workshop will be held on October 13–14 2007. You can sign up for the announcement mailing list at Google Groups.

06/22/07 Announcing PPW 2007 - October 13,14 2007

The Pittsburgh Perl Mongers are pleased to announce The PITTSBURGH PERL WORKSHOP 2007, a two-day, low-cost conference on Saturday and Sunday October 13-14, 2007.


The Pittsburgh Perl Workshop is an annual conference dedicated to the Perl programming language. In 2006, the Pittsburgh Perl Mongers broke new ground by hosting the first Perl Workshop based in the United States. This year, the Perl Mongers are expanding the Workshop to a two-day format. As always, the 2007 Workshop is designed to provide you with a comfortable, exciting, and enjoyable learning experience. It is structured as a series of short lectures, but the atmosphere is low key and engaging – the perfect combination to open your mind and then cram it full of good stuff.


After last year's conference, you gave us feedback – a lot. We listened. This year, we are giving you what you asked for:

  • The workshop has expanded to a two-day event to allow for more talks, BOF's, and social interactions.
  • We will be adding a one-day course for programmers with little or no Perl experience. This course will be given by a world-class Perl trainer.
  • The schedule has become more relaxed to allow for more peer interaction.
  • Scheduling of sessions has been improved to maximize flexibility in attending the sessions you want to attend.
  • The web site is now powered by "A Conference Toolkit" (ACT)

The Workshop will be held at Carnegie Mellon University in the University Center building. The CMU campus is located in Oakland, part of Pittsburgh's wonderful East End.


Registration details will be announced at a later date.


The call for papers is officially open! Talks are available in 20 minute, 50 minute or lightning talk durations. This year's theme is "Hands On Perl." What does this theme mean to you? We want to know. Please visit http://pghpw.org/ppw2007/newtalk to submit your proposals.


The Pittsburgh Perl Workshop relies heavily on sponsorship to make the conference low-cost for attendees. Please consider sponsoring the workshop financially. In return, you can send people to the workshop for free, promote your organization, and get a warm, happy feeling inside. It's a good deal. See the sponsorship prospectus for more details:


Allison Randal informs us that she has "...just signed an agreement with O'Reilly that assigns the full copyright in the book Perl 6 and Parrot Essentials to The Perl Foundation. The text is out-of-date, but can be updated much more rapidly than it can be rewritten from scratch." The contents of the book will soon be available via the perl.org Subversion server (svn.perl.org).

Many thanks to O'Reilly for this generous gift to the Perl community, and to the original authors for their hard work in producing the book in the first place.

On behalf of the Parrot team, I'm proud to announce Parrot 0.4.13 "Clifton." Parrot (parrotcode.org) is a virtual machine aimed at running all dynamic languages.

Parrot 0.4.13 can be obtained via CPAN (soon), or follow the download instructions at http://parrotcode.org/source.html.

Parrot 0.4.13 News:

  • Languages:
    • Updated Lisp, Lua, PHP ("Plumhead"), Python ("Pynie"), ABC, WMLScript, and Tcl ("ParTcl").
    • Perl 6 passes all of the sanity tests.
    • PGE supports latest Perl 6 grammar syntax. Perl 6, Python ("Pynie"), and ABC parsers updated to match.
    • Updated PHP ("Plumhead") to Antlr 3.0.
    • Lua added the beginnings of a PGE/TGE based compiler (not yet replacing the Perl/Yapp compiler).
    • Lisp updated for current features, added a test suite.
  • Core Implementation:
    • Filled in features and backward compatibility for PDD 15 objects. New object metamodel passes 85% of old test suite.
    • GCC API symbols are visible externally only when explicitly exported.
    • Added generated GCC compiler attributes to increase warnings, and cleaned up resulting warnings.
    • Code cleanup efforts and fixed memory leaks by the cage cleaners, resulting in notable speed increases.
  • Misc:
    • Updated Parrot distribution to Artistic License 2.0, from dual Artistic 1/GPL license.
    • SDL examples brought up-to-date with current features.
For those who would like to develop on Parrot, or help develop Parrot itself, we recommend using Subversion or SVK on the source code repository to get the latest and best Parrot code. The next scheduled release is July 17, 2007.

Thanks to all our contributors for making this possible, and our sponsors for supporting this project.


On Saturday, 16 June 2007, please join us on IRC in #parrot (irc.perl.org) to work on closing out as many RT tickets as possible in the parrot queue (https://rt.perl.org/rt3/) . This will help us get ready for the next release of parrot: 0.4.13, scheduled for Tuesday 19 June 2007. You'll find C, Parrot assembly, Perl, documentation, and plenty of tasks to go around. Core developers will be available most of the day to answer questions.

No experience with Parrot necessary.
