The New York Linux User's Group invites you to a special presentation by Alex Martelli of Google, on the Python Object Model. This presentation will be held at P.J. Clarke's Sidecar, rather than our usual location, and Google is picking up the tab for an hour and a half of open bar and food. Additionally, if you're looking for a job as a Python developer, bring your resume. Please RSVP at http://rsvp.nylug.org to attend, as seating is limited. - Ron (announcement follows) The New York Linux User's Group Presents Alex Martelli - on - The Python Object Model Held at P.J. Clarke's Sidecar 915 Third Avenue @ 55th Street - NY Python is a multi-paradigm programming language, but, out of the paradigms it supports, there is no doubt that OOP (Object Oriented Programming) is the paradigm that forms Python's core. If you have done any substantial programming with Python, you have, most likely, used some of its OOP features. But -- have you ever stopped to really think about those OOP features, the mechanisms that Python uses (and exposes!) to implement them, and how best to make use of the possibilities this state of things offers? This subject is generally known as the "Object Model" of a language. This talk stops a bit short of examining every level of Python's Object Model -- in particular, it does not get into metatypes (metaclasses) and similar levels of "Black Magic". Rather, the talk sticks to the most practically interesting aspects of Python's Object Model as seen from the point of view of a programmer using Python -- understanding exactly what's going on in all kind of everyday OOP-usage situation, what alternatives and trade-offs these mechanisms imply (for example, when should you use closures, and when should you use functors instead? when to inherit, and when to delegate instead?), and how Design Patterns play into the mix (Python subsumes and build-ins some classic DPs, and makes a few others irrelevant due to its highly dynamic typing, but other classic DPs yet remain extremely relevant and important for optimal day to day use of OOP in Python). About Alex Martelli ------------------- Alex Martelli is Uber Technical Lead at Google, in Production Software. He wrote Python in a Nutshell and co-edited the Python Cookbook, and is a member of the Python Software Foundation.

Meetings are free and open to the public, but require advance RSVP due to fire code and security requirements at our usual meeting space at the IBM Building. Our announcements mailing list at http://nylug.org/mailman/listinfo/nylug-announce provides a low-volume but steady stream of Linux, Free and Open Source, and related community and other user group announcements for the tri-state area. Our technical discussion list is a moderate-volume list featuring a diverse group that from home users to enterprise security experts. http://nylug.org/mailman/listinfo/nylug-talk http://www.nylug.org/
