    Update -- Now participating also: New York, Atlanta, Philadelphia, Chicago, Sydney Australia, Turkey, and other parts of the the EU

    You could call it the's "Winter of Code". You could call it a contest. You could call it fun. You could call it Perl...

    ...And you'd be right. (so far joined by -- all groups invited) is holding in a competition that runs from now until January 8th when the code of each competitor will be pitted against the others in a live Google hangout world-wide Perl Mongers meeting.

    The aim of the competition is to "deduplicate" 100 gigabytes of random file data, using Perl, as fast as possible. If your code can do it the fastest, without killing the contest server, you win. The winner gets to choose the topic of the next hackathon competition (and/or host it), and gets the recognition of having won a world-wide competition in Perl.

    The competition is open to all, provided a few criteria are met which establish legitimacy of participation. YOU'RE INVITED!

    Full details can be read on the website.

    The contest is discussed on The mailing list

    The hackathon was organized by Tommy Butler and John Fields of Dallas, TX, and is being hosted by the Dallas Makerspace.

    Our resources are finite, so we may have to stop accepting entries if server load gets too high. Get your notice of intention to participate to the mailing list asap.

    Greetings, Monks.

    As I toyed with the notion of creating a JavaScript to Perl converter; I stumbled across a table. While seasoned veterans of both languages may not have a need for it. I thought it still might be a nice reference, for quick-n-easy comparison of both languages. To others needing this sort of information.

    You can find it here: Equivalents in JavaScript and Perl

    Best wishes.


    EDIT: corrected typo to the external link -- thanks zentara. :)

    Dear Youngster,

    this year my wishing-wells come from irish lore:

    May the Good Saints* protect you,
    And bless you today.
    And may troubles ignore you,
    Each step of the way.

    May your life be a constant source of joy for you.

    cheers and all the best
    from a old fart

    *) which are, of course, the Perl Saints

    Unfortunately because SAP Sybase's OpenClient is proprietary, it can't be included in the ActiveState Perl PPM repositories. I've built the latest DBD::Sybase (1.15) for Activestate Perl 5.16.2 (Win32) for everyone. Get it here.

Yet Another XS Tutorial

    Hello. I recently had to figure out how to use a C library from Perl (which means using XS, obviously). Since that felt a bit harder than it ought to, I tried to write down what I learned, in the hope that it may help someone else not have to do the exact same mistakes I did. The text is mainly intended to give a basic understanding of how things work, to the point where the ordinary documentation becomes understandable. It also gives recommendations for what docs to read in which order. If this sounds interesting, you can find the text on my work's blog.

    The text is also available in less Javascripty form on github. There you can also see the code examples in useable form.

    3D stereo cameras save in a format called MPO. Script uses Perl to make calls for splitting the left and right, then recombining as a cross-eye stereogram for posting on the web.

    Hi all. Long ago I promised an explanation of why Perl hash function was changed in 5.18.

    You can read up on it here

    Sorry it took so long, many vendors did not patch for a long time.


Concurrency in Perl 6

    »»» Caution: this post is about the immature Perl 6, not the rock solid Perl 5 «««

    A quick summary of recent news on concurrency in Perl 6:

    • jnthn has recently published a nice set of slides ("Composable Concurrency in Perl 6") that defines terms (especially "asynchrony", "parallelism" and "concurrency") and introduces the current rationale behind the design of Perl 6's concurrency features.

    • jnthn also wrote a completely new Perl 6 Concurrency Synopsis.

      (This is a pleasant read, replacing the relatively incoherent old Perl 6 "Processes and Concurrency" synopsis document.)

    • Most of the features mentioned in these new documents have already been implemented (on Rakudo/JVM).

    • The naming of things is undergoing rapid change right now, eg the async keyword has just been renamed start in the spec but is still the former in current Rakudo/JVM.

    If you're interested in concurrency features and would like to participate in their development for Perl 6, please visit the #perl6 IRC channel and join in the discussion.
