Next meeting will be on 5 March 2012, as usual at Common Roots (www.commonrootscafe.com) in the Community Room. However, our start time is *NOT* as usual. Our meeting will start at 7:00 PM (the room is reserved by another group until 7:00 PM); figure that the talk will start at 7:30PM. Some of us are likely to be there starting around 6:00 PM to eat dinner, etc.

CL-MW: The development of a Master/Worker framework in Common Lisp

CL-MW is a Common Lisp Master/Worker framework for rapid prototyping of pleasantly parallel applications with fine-grained tasks. It focuses on low cognitive overhead for application development, easy integration with well-known batch scheduling systems, and scalability in the ~10K worker and the billions of tasks range. Hear about the challenges and solutions in the development of this framework.

If you haven’t started your entry for the TC Lisper’s Programming Contest, you’re not too late. The deadline is September 19th.

If you have started, post a comment here or there to let us know how it’s going!

Your Lisp program will be given two input images from the same web cam. The first image will contain zero people, the second image will contain at least one person.

Your program’s goal is to find the people. You will get points for emitting the pixel coordinates of a pixel inside a person. You’ll get bonus points if it’s a head pixel. Be careful, though. You’ll lose points for emitting more than one pixel per person.

• Deadline: September 19th.
• Target Platform: SBCL or Clozure under Mac OS X (10.6.4).
• Prizes for: Tournament winner, Prettiest code
• Full Details: http://tclispers.org/contest-find-the-people

Apology: Unfortunately, ScreenFlow bombed out on me when I went to stop recording. It subsequently saw that it had a partial project there but was unable to recover it. As such, there is no video available for this presentation. Feh. — Patrick
