Vancouver Python/Zope/Plone Meeting Reminder
Tuesday January 4th is the first Tuesday of the month and the Vancouver Python, Zope and Plone user's group will have its monthly meeting at ActiveState. The topic is "What's new in Python 2.4": Among other things, we will discuss: * Function/method decorators * Generator expressions * Built-in sets * Unification of integers More information is available here: http://www.vanpyz.org/news Topics for the next few months have also been tentatively scheduled: January 4, 2005 What's New in Python 2.4, Paul Prescod February 1, 2005 Creating OS X Cocoa Applications Using XML and Python, Dethe Elza March 1, 2005 GNU Radio and Python, Ian Caven April 5, 2005 Large Scale Python, TBD Paul Prescod -- http://mail.python.org/mailman/listinfo/python-list
Re: Problem parsing namespaces with xml.dom.minidom
You've reversed some function parameters. Here's a program that works
fine (note that you don't need to set up a SAX parser):
from xml.dom import minidom
text = '''
alias
Thu Jan 30 15:06:06 NZDT 2003
Nothing
'''
# Parse the string into a minidom
mydom = minidom.parseString(text)
# Look for some elements
# This one shouldn't return any (I think).
object_el1 = mydom.getElementsByTagName("xte:object")
# This one definitely should, at least for what I want.
object_el2 = mydom.getElementsByTagNameNS(
'http://www.mcs.vuw.ac.nz/renata/xte',"object",
)
print '1: ' + str(object_el1)
print '2: ' + str(object_el2)

Vancouver Python/Zope/Plone: Creating OS X Cocoa Applications Using XML and Python
February 1, 2005
Creating OS X Cocoa Applications Using XML and Python, Dethe Elza
This talk will cover the use of Renaissance and Python to develop
programs for OS X, focussing on both rapid application development, and
ease of maintenance. Renaissance is an XML dialect for describing Cocoa
(or GNUstep) user interfaces, which can be used as an alternative to
Apple's binary NIB format. It grew out of the GNUstep? project and is
intended for use with Objective-C, but works seamlessly from Python with
the PyObjC bridge.
Hosted by ActiveState ("a division of Sophos") at 580 Granville St.,

Vancouver Python User Group Reminder
Tuesday March 1st is the first Tuesday of the month and the Vancouver Python, Zope and Plone user's group will have its monthly meeting at ActiveState (580 Granville) at 7:00. The topic is GNU Radio and Python. GNU Radio is a free software implementation of Software Defined Radio. "Imagine if the only thing stopping your handheld PDA from simultaneously being a GPS receiver, phone, radio or miniature TV was your willingness to download and install some free software program." "We're pretty much turning all hardware problems into software problems," Blossom says. "We want to facilitate evolution in the radio arena." "A software radio is a radio whose channel modulation waveforms are defined in software. That is, waveforms are generated as sampled digital signals, converted from digital to analog via a wideband DAC and then possibly upconverted from IF to RF. The receiver, similarly, employs a wideband Analog to Digital Converter (ADC) that captures all of the channels of the software radio node. The receiver then extracts, downconverts and demodulates the channel waveform using software on a general purpose processor." GNU Radio is a hybrid C++ / Python system. The primitive signal processing blocks are implemented in C++. All graph construction, policy decisions and non-performance critical operations are performed in Python. All of the underlying runtime system is manipulatable from Python. Upcoming talks: April 5, 2005 Large Scale Python -- http://mail.python.org/mailman/listinfo/python-list
Reminder: Vanouver Python Meeting Tonight
DateTime: April 5, 2005, 7:00 PM Place: http://www.vanpyz.org/ActiveState Topic: Python Quirks, Warts and Complaints Nothing is perfect: even Python. This meeting will be an opportunity for Python programmers to get together and learn from each other. We'll go through issues we've run into and things we would like changed in future versions of Python. The discussion will start with a presentation based on a talk from last year's conference. From there we'll open the floor to everyone. More information: http://www.vanpyz.org/ (or reply to me) Paul Prescod -- http://mail.python.org/mailman/listinfo/python-list
May 3: Vancouver Python, Zope and Plone User's Group
This month's talk: 10 coolest things about Plone, Andy McKay
This talk was originally supposed to be: "137 cool things about
Plone" but we negotiated Andy down to just ten. But these ten things are
not just cool: they are the coolest. Plone enthusiasts and hecklers
equally welcome.
The group meets monthly (first Tuesday of each month) at 7pm. It is
hosted by ActiveState ("a division of Sophos") at 580 Granville St.,
Vancouver
