About the Talks 

   Factory is an object-oriented approach to partial function 
application, also known as "currying." Python 2.5 added support 
for currying with the addition of functools.partial: 
http://docs.python.org/whatsnew/2.5.html#pep-309-partial-function-application
The Factory module is a more powerful implementation of this pattern.  

Some improvements include:
- safer, as invalid arguments are detected immediately, instead of  
at call time
- intelligent support for classes, instance methods, and all other  
callables
- bound arguments can be inspected and modified as attributes
- several convenient methods for (re)binding arguments

   Using Factories can:
- simplify writing callbacks
- reduce bugs in concurrent applications
- provide easy lazy evaluation 

   This talk will demonstrate the Factory module and discuss its  
implementation and uses. Familiarity with currying is helpful but 
not required. 
   More information is available at http://pypi.python.org/pypi/Factory/


   Tonight's second talk is a PyDev primer, which will cover the basics 
of PyDev and PyDev Extensions.
