I have two different versions of a Perl module.

Dynamic loading and symbols sharing
Hi, I'm trying to load a module library via dl in such way, that the module can access globals from the main application. How is that possible to do?

Writing Python packages with multiple C modules
Hello, I am writing a Python C extension which uses the pygame C API. So far so good. Now I wonder how I organize my source code so that I can have multiple submodules in the package.

Parent App access vs Events in Flex Modules
Inspired by this Flex question, is it seen as better practice to dispatch an event back to the parent app, as opposed to calling a method on the instance of the parent app, from within a module? To me it seems that the module shouldn't know what methods are available at the parent, as such approach leads to tight coupling. Thoughts? ...

Launching code for Javascript modules
Most of the javascript I work with is UI code - code that attaches additional functionality to the HTML framework of my pages and interacts with various HTML elements.

How bad is it to override a method from a third-party module?
How bad is it to redefine a class method from another, third-party module, in Python? In fact, users can create NumPy matrices that contain numbers with uncertainty; ideally, I would like their code to run unmodified (compared to when the code manipulates float matrices); in particular, it would be great if the inverse of matrix m could...

Is there a way to set a Module to behave like a static class?
This questions is for VBers, it's irrelevant in C#. In VB, when you create a module, all it's fucntions and members are available in the scope without need to type the module name, just like all the VB functions (Rnd, Mid, IIf etc.). I want to create a module but I should have to explicitly write it's name to access it's members, i.e. ...
