Investigated stability regions for high order deferred correction schemes; see this notebook.
Finally, after about a year of searching, found a way to redirect all output from distutils to a file. This will avoid the massive amount of warnings that are currently printed to the screen when installing PyClaw. See the patch here, based on this StackOverflow answer.
I also put together an IPython notebook on shallow water solitary waves over periodic bathymetry. It will be in the Github repo soon.
