The request classes use a Python built-in Event class instance to communicate with the main controlling thread when processing is complete. Python made this application of threading incredibly easy.

  • Python Software Foundation: Minutes of Board of Directors Meeting (July 12, 2005)

    ...centered on the issue of migrating the Python codebase from CVS to SVN: Whose decision would it be to move from [SourceForge's] CVS to SVN? If the python-dev crew want to move to SVN, they should. If they don't, they won't. The PSF should facilitate what they need with cash or whatever, but it's about letting people do the work the way they see fit. Nobody acted on converting from CVS to Subversion because nobody felt they had the power to do so. SourceForge is studying SVN for possible futur...

Deibel asked if the PSF should set aside some money to fund PyCon attendees. Last year the board didn't plan ahead and the system was somewhat unfair.

Christian and I both had previous experience with Python, but primarily as a scripting language to process text or automate miscellaneous tasks. I went to PyCon 2004, and was shocked by the number of interesting projects that were developed and maintained by lone developers or very small teams. I was particularly impressed by the demos and presentations given by the Twisted team. We briefl...

This model, known as the ERP5 Universal Business Model, makes it possible to reuse code by abstracting away from the specific domain and encapsulating the generic relationships and actions common to many business processes. As a result, modules as different as Payroll and Invoice can share almost of all their code. In this example of the ERP5 Universal Business Model, Movement allows the transfer of a quantity of resource ...

  • Unifying types and classes in Python 2.2

    ...classes are more accessible and less dangerous. Terminology-wise, a metaclass is simply "the class of a class". Any class whose instances are themselves classes, is a metaclass. When we talk about an instance that's not a class, the instance's metaclass is the class of its class: by definition, x's metaclass is x.__class__.__class__. But when we talk about a class C, we often refer to its metaclass when we mean C.__class__ (not C.__class__.__class__, which would be a meta-metaclass; th...
