I think most of the Python presentations went well, but we had two less 
than planned due to an unexpected surgery for one presenter and 
business demands keeping another away. I was unable to fill those slots 
with backup Python sessions, so other hot topics took their place. Ruby 
on Rails certainly seemed to have the buzz.

I wasn't that happy with my own presentation as I somehow managed to 
get a version of wxPython on my Mac with a TextField display problem 
and didn't realize that until it was too late to back out to another 
version. Like always though, I think I picked up a few more new users. 
I would like to figure out a better sample application that can be 
built in 15-20 minutes and uses more advanced controls like 
MultiColumnList, BitmapCanvas, etc. rather than doing the simplistic 
mortgage calculator which is a bit boring.

OSCON presentations are available at:

It is up to the presenter to get O'Reilly the slides, but if you don't 
see a presentation that you're interested in, you can always send an 
email to the presenter reminding them to mail their slides to Vee at 
O'Reilly.

There weren't any PythonCard 2.0 brainstorming discussions. I'm happy 
to schedule an IRC session on freenode in the next week if many people 
are interested, otherwise I'll probably just start making posts to the 
pythoncard-devel mailing list on various topics.

BTW, after bringing up Anti-Grain Geometry and the lack of anti-aliased 
full alpha channel support in wxPython during a discussion at OSCON I 
found out that Fredrik released aggdraw earlier this summer.

http://effbot.org/zone/draw-agg.htm

Turns out that there was also a small proof of concept for wrapping 
aggdraw calls in the wxPython DC API.

http://www.averdevelopment.com/python/wxAGG.html

The code will work with Python 2.3 if you simply add a

from sets import Set

and change set( to Set( in the code so it doesn't rely on the Python 
2.4 built-in. It is pretty easy to imagine doing a BitmapCanvas that 
supports aggdraw using the same API, but I haven't started working on 
it yet. I want to see some transparency drawing calls and whether that 
needs to just be a global flag like autoRefresh or something rolled 
into each method call. Anyway, this could get me working on another 
sample :)
