  • About: I blog about Perl.
  • Commented on I'm wondering how to learn good perl
    Try http://learn.perl.org that should get you started with Perl in general. I'd also recommend learning how to get on IRC and hanging out on some of the common Perl support channels. See http://www.irc.perl.org/channels.html for channel info. Welcome to the community!...
  • Commented on Moose-iplicity
    Its a neat trick but I wonder if tying the orchestration / object initialization logic in that way isn't a bit too much implementation details in the interface? You could more carefully separate it (and avoid tying yourself to Moose)...

  • Commented on The Hot New Language Named Rakudo
    The issue with naming this new language Perl6 is two fold: 1) The vast majority of people in IT that are outside the Perl community see the slow development of Perl6 as proof the language is a dead end. I...
  • Commented on Because CPAN Needs More Templating Modules
    I like it since I'm a fan of strongly typed interfaces for the template. I'd love to take it even further, like the template is a subclass of Template::Compiled::Class and the class attributes and methods are exposed to the template...

    Great post and thanks for sharing your success. I think Perl needs more PR like this. If you don't mind me asking, did you consider Catalyst for your project and if so I'd love to heard the reasons for rejection....

  • Commented on Perl 6 Is Slower Than My Fat Momma!
    I'm glad you seem really passionate about Perl6 but I'm not clear after reading this if I understand how some of these problems are being addressed. I think it would be better to have a little more humility here, instead...
  • Commented on On The Mojolicious Codebase
    From where I stand it appears that Mojolicious attracts a different type of person to Perl than perhaps us ‘old schoolers’. Historically Perl and CPAN has followed the Unix philosophy of ‘do one thing and do it as good as...
  • Commented on Perl 6: The Next Node.js, Done Right
    I think the issue with NPM here has shown a defect in the corporate patronage model of open source, rather than any defect in Javascript as a language. Perl (and Perl6) has done the hard work of building a community...
  • Commented on Perl6 module namespace
    It would be nice if it was better organized but that's probably not going to be easy in such a decentralized project. In any case its no worse than npm or github. It makes discovery harder, yeah that's a problem,...

    Thanx for the comment Wayan. I'm always glad to see folks jumping into the discussion.

    > * some unspecified action for which foo and bar are needed, which is the sole purpose of Thing instances

    Well a couple of things here:

    • This is just an example. Reading from a config file is a pretty basic thing to write example code for, and it's…

  • Wayan commented on Moose-iplicity

    k, no universally bad design.

    Most of my comment comes from the fact that I am very much dependency injection oriented.
    For me the foo, bar are the dependencies of $thing thus they should be passed to it
    - most naturally as simple and required arguments of constructor. Where the caller
    of Thing->new(..) gets them is another thing.

    When I accept this, there is no room for Thing to initialize the arguments and dereference them from the config bunch.
    Thus there is no space (in this particular example) for Moose cleverness
    like Moose::Meta::Attribut…

  • Wayan commented on Moose-iplicity

    Sorry for typo. "k, no universally bad design" should be "Ok, no universally bad design"

  • Yuki Kimoto commented on SPVM is now 6x faster than Perl 5.26.

    SPVM maybe bind cuda(GPGPU) easily. If so, Perl parallel calculation is available.

    And maybe bind OpenMP, SIMD easily. These are CPU paralel processing.

    Well, sure: if you don't need lazy attributes to solve your problem, then you don't need this pattern. But, also, if you don't need objects, you don't need this pattern. ;-> (And we could continue in that vein forever, basically—if you don't need software, if you don't need a computer, if you don't need technology ...)
