Python Web Frameworks - Django and Pylons

The two dominant python-based web frameworks are Django and Pylons. They can be used to deploy web applications such as news sites, online ticket tracking systems, or wikis. An overview and comparison of Django and the recently reinvented Pylons Project will be presented. Individual dependencies of the Pylons Project will be described including the Pyramid WSGI engine, the SQLAlchemy database Object Relational Mapper (ORM), and the Mako HTML template generator. A very simple blog engine will be implemented as an instructive example.

March 2012 Meeting

Unity is the new desktop environment for Ubuntu, having first premiered in
version 11.04, significantly enhanced with version 11.10, and very much the
cornerstone of the upcoming 12.04 release.

A striking departure from Gnome 2, Unity has been seen as a source of
controversy in the Linux world.

This talk will outline some of the design goals that Unity addresses, noting
strengths, weaknesses, and improvements across the three versions of Ubuntu in which it's been included.

While Unity offers many usability affordances, some Ubuntu users prefer to
customize it for their specific workflows. Linux is famous for its
customizability, and Unity is no exception if you know which tools to look

This presentation will outline some of the tools available through the Ubuntu
Software Center to show you how to customize the Unity interface.
