Need help looking for this blog/tutorial: small nano sized sets of codes/examples as proof of concept for of ML/deep learning concepts

I’m looking for this blog post, that consists of a number of example codes that shows small examples of some deep learning or machine learning concepts.

Each of the code segments are timed, and they’re all pretty terse.

It’s been helpful to me, but I can’t find it any more.

Anybody else know which article I’m talking about? (Can you gimme the link? )
