 Django!
 Python rapid application development
framework
 Python Imaging Library for some of the

11. Django Background
 Started in 2005 by a newspaper in Kansas
 Open source
 “The Framework for perfectionists with
deadlines”
 Key features
 Clean Object-relational mapper (your Python
classes become database tables)
 Easy templating system
 Nice, clean URLs

16. Lessons Learned
 Planning ahead and doing the dev work over
summer was critical
 Students are opinionated and will have many
“wants”; trick is to prioritize them
 Your interface design does impact quality &
tone of submissions
 Likewise, if you make it easy for Teaching
Assistants to provide feedback, they will

17. Next Steps
 Courseapp is available at http://
hci.stanford.edu/research/courseapp/
 Open Source
 SVN repository & trac for bug management
 Will be used in future design classes at
Stanford, and hopefully other schools
 Deploying for a different class (CS294h) this
quarter took only 2 lines of changes
