  There is some refactoring we can do, but not as much as you'd think: These are all client modules of the framework. They're the implementations. They get/put data from/into databases (7, including CSV and JSON), they get data from various...
• Posted Thoughts while changing the API of a massive framework... to preaction

  At the Bank we have a home-grown ETL framework that we've been using for quite some time. We recently completed a total rewrite, but unfortunately we left out a few changes. Had I gotten those changes in 5 months ago, I would have only had to break the API of about 10 modules. Today, in order to…

  "Man-hours" could have been perfectly innocent. "I refuse to acknowledge the term man hours, you patriarchical pig," made "man-hours" fully self-aware, and then belittled everyone who might have said "Hey, you know, you could have just said 'hours' here." This...

  The DAOInterface role is just an interface. By implementing the required methods, you can create an implementation that you can then give to another object. So I could have a DBIx::Class implementation of the DAOInterface, or a MongoDB implementation of...

  I'd argue that choosing one of the web frameworks would immediately invalidate all others. CGI.pm is an interface, not a framework. PSGI is an interface, Plack is what implements it (maybe even too richly). The people who choose not to...

• Posted Using MooseX::Types to inflate config values to preaction

  For a large application, configuration files become a necessity. They help flexible code be used in multiple instances across multiple modules. But they are, for the most part, only data structures, which can be a problem if the configured object is expecting another configured object.

• Posted Run-time Class Composition With Moose to preaction

  Moose is great! At its very basic, it simplifies the boilerplate required to create Perl objects immensely, providing attributes with type constraints, method modifiers for semantic enhancement, and role-based class composition for better code re-use.

• Duncan commented on Fat Versus Thin Core

  I think the premise of downloading a thin core and then an extended core is quite solid. I've come across two examples recently where other programs do this.

  I was working on a fresh Ubuntu installation and I couldn't get the Vim syntax highlighting to work. I went to the sys admin and asked him to download the full version of Vim. He knew immediately what I meant and once he had done it I had all the vim features I needed. I didn't have to keep going back.

  Later, on the same installation, I couldn't get our Perl modules to install because there wasn't a C compiler. Once I nu…

  Python has WSGI and Django and Ruby has Rack and Rails, and none of them are shipped with the language core.

  
  

• Joe McMahon commented on What exactly is going on at Perlmonks?

  The problem with, "well, it was just one bad joke" is that it's the death of a thousand cuts. Yeah, that one little thing this person did "wasn't that big a deal". And the one this other person said wasn't really supposed to be insulting. And these people didn't really mean to exclude you.
  

  
  It adds up. It's the emotional equivalent of repetitive stress injury. Overusing your hand today wasn't that big a deal, it's just a little sore. Do it over and over for months, and suddenly you hurt so bad you just can't type anymore.

• Pedro Melo commented on Fat Versus Thin Core

  I would prefer a thin Perl core, but not until we can install modules without super-user permissions on any system and having them recognised immediately by perl.

  The path to this nirvana-like place is not that hard:

  1. settle on ~/.perl5/local [1] as your own personal "local::lib" source;
  2. make sure perl always sources /etc/perl5_policy.pl first: this should take precedence even over sitecustomize.pl which is a per-library file;
  3. distribute a default perl5_policy.pl file that, if running as a non-priviledged user, and if ~/.perl/local exists, prepends the …
