    Along with the clone feature I added last cut that allows you to clone instances for specific projects/purposes, this new version provides a fetch command that automatically updates the Perls that are available, displaying the most recent point release available for each major version.

    If any of your existing installed versions don't match what available lists, we'll automatically register those instances as custom, which allows them to continue to be maintained by berrybrew. Here's the full blog post.



Github makes your code, your code

    I applaud this decision by Github, as it allows expression to be expanded without fear. I do understand the concern that an employer could have (as I did run a few small businesses), but hacking out a few lines of code while at work during a break, for Open Source projects shouldn't be claimed as corporate IP.

    This is a thing of opinion depending on the reader, but I digress. I am totally in favour.

    What's mine is mine.

    In other news, it is critically important to actually read the documents you sign when you start on with a new employer.

    This was posted at Perl is dead over on with that title (here's the actual follow-through link to the real article). The title is over the top, but this topic has been brought up here recently, so I thought I'd put it here for our mathematicians/statisticians and other interested Monks.

    Personally, I don't care. I love Perl, and likely always will. I have learned other languages while knowing Perl, but as I learn other languages, I just learn new ways to incorporate what I know into Perl. Learning new things and incorporating them into experience I've gained is how I approach everything anyways.

    Hello! is glad to annonce new module Protocol::FIX to parse and serialize FIX messages (Financial Information eXchange).

    With the module it now becomes much more easy to create your own FIX-client or FIX-server in Perl.

    Any comments or feedback are very welcome!

    WBR, basiliscos.

Interest in Perl as a "weekend" language rising

    Of note: The top weekend programming languages — based on GitHub’s activity

    And in my estimation, the recent, highly publicized StackOverflow analysis is probably severely flawed because once all the popular questions are answered, they generally never have to get asked again and so fewer questions would have tags from languages that have been around awhile. So their analysis would skew toward brand new languages. Using GitHub would seem to be a much more accurate sample method.

New Perl 6 book coming out with O'Reilly

    Dear sisters and brothers,

    it is my pleasure to announce that O'Reilly has posted an early release (i.e. incomplete and not fully edited version) of a new book on Perl 6:

    Think Perl 6 - How to Think Like a Computer Scientist

    by Laurent Rosenfeld (with Allen B. Downey)

    Early Release Ebook ISBN: 978-1-4919-8048-4 | ISBN 10: 1-4919-8048-6

    At this point, only the first seven chapters (about 150 pages out of a total 450 pages) are publicly available as HTML. The book is fully written, the rest only needs to be processed in O'Reilly's editing process, which should take another few weeks.

    If you want to learn how to program and think like a computer scientist, this practical guide will get you started on your programming journey with Perl 6, the new version of the popular programming language. Ideal for beginners, Think Perl 6 contains numerous exercises with multiple solutions and over 1,000 code examples. Even experienced programmers will learn a lot from this book, especially those familiar with Perl 5.

    In an interview with LinuxVoice (July 2015), Larry Wall said: “We do think that Perl 6 will be learnable as a first language.” Hopefully this book will contribute to make this happen.

    If you see anything that would need to be corrected or that could be improved, please kindly send your comments to the following address: think (dot) perl6 (at) gmail (dot) com.

Are Restricted/Locked Hashes a Failed Experiment?

    demerphq kicked off a discussion on of the hash APIs that Perl (and perl) provides. The discussion also has a parallel strand on

    In my interpretation, the discussion moved on from removing restricted and locked hashes towards realizing that restricted and/or locked hashes can get a different hash implementation in the backend than plain hashes and maybe even plain hashes can get different implementations. This makes me somewhat happy because I really like using locked hashes for DBI query results and don't really care for the (potential) performance overhead.

    Other people see a benefit in removing the performance overhead incurred by supporting restricted hashes, which I don't know about. But as these people know more about the internals, I'm inclined to trust them on their judgement as well.

    Allowing different implementations of hashes opens up the interesting question of if or how a hash can move from one implementation to another, and personally I expect that only to happen for explicit assignments:

    use feature 'superfast_hashes'; my %hash_with_implementation_A = ( foo => 'bar' ); no feature 'superfast_hashes'; my %hash_with_implementation_B = %hash_with_implementation_A;

    If you have an opinion either way on the features of locked / restricted hashes, consider participating in the discussion either on or

    Because of the hard work of Kenichi Ishigaki (ISHIGAKI on CPAN, charsbar on IRC), Text::CSV is back in sync with Text::CSV_XS again. That must have been an awful lot of work. THANK YOU!

    Enjoy, Have FUN! H.Merijn
