I think this is a great idea. In fact, when I do an intro to numpy, I spend
a bit of time on those issues, 'cause I think it's key to "Getting" numpy,
and not something that people end up learning on their own from tutorials,
etc. However, in my  case, I try to jam it into a low-level intro, and I
think that fails :-(

So doing it on it's own with the assumption that participant already know
the basics of the high level python interface is a great idea.

Maybe a "advanced" numpy tutorial for SciPy 2017 in Austin also???

Here is my last talk -- maybe it'll be helpful.

http://uwpce-pythoncert.github.io/SystemDevelopment/scipy.html#scipy

the strides stuff is covered in a notebook here:

https://github.com/UWPCE-PythonCert/SystemDevelopment/blob/master/Examples/numpy/stride_tricks.ipynb

other notebooks here:

https://github.com/UWPCE-PythonCert/SystemDevelopment/tree/master/Examples/numpy

and the source for the whole thing is here:
