This is awesome, many thanks.

Jeremy, I know you're a fellow fan of J -- is it possible to do modern ML with J? It seems like numpy is just a worse version of the array paradigm from J/APL, but I'm guessing all the specialized ML packages are the real value of python here? Any idea of anyone has done similar work in J?

Has the classic ML course been deprecated? I noticed that following link no longer works: https://course.fast.ai/lessonsml1/lesson1.html

EDIT: looks like they've been moved to the following link instead: http://course18.fast.ai/ml.html

Is there a way to create lifestyle config for Sagemaker manually instead of using fast.ai created IAM ARN and config?

What are the main differences with last year's course ? Also can we expect http://course18.fast.ai/part2.html to be updated in the near future ?
