If you're wanting to speak at Pycon.ca you need to get your proposals in this weekend.  Don't delay.

[Update] Yeah, Mike, do that.  I now have way too many talks I'd like to do:

• Modern OpenGL Eat Your Vertices Raw (submitted)
• Profiling for Performance (submitted, but very brief outline)
• Using GStreamer 1.0 (an HTML5 Video Odyssey)
• The Observer Pattern: Django Signals, PyDispatcher and Caches
• Introduction to Ctypes
• or Pygame
• Multicast Sockets or mDNS (lightning talk?)
• Using lxml.etree and xpath (lightning talk?)
• Controlling Open Office with Python/PyUNO (lightning talk?)
• Using Memory Mapping to Load Quake Maps with Numpy (lightning talk?)
• Using Memory Mapped files with posix_ipc (lightning talk?)

Moral of the story, sit down to work out what talks you'd like to do well before the final weekend.
