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: https://github.com/UWPCE-PythonCert/SystemDevelopment/blob/master/slides_sources/source/scipy.rst All licensed under: Creative Commons Attribution-ShareAlike -- so please use anything you find useful. -CHB And Julian's temporary work lends itself to a very nice talk, more on > Python internals than on NumPy, but it's a very cool subject nonetheless. > > So my thinking is that I am going to propose those two, as a workshop and > a talk.
