Holy grails of free, online courses?

I like the Python course on HackerRank.

Not necessarily tech-related, but I consider Ableton's online music classes to be a brilliant gift to the online portion of humanity:

There's cs61a:

(I'm doing the Denero version: https://cs61a.org/denero.html) If you pass the command-line flag: `--local` you can run the tests without triggering the submission system.

The moocs from University of Helsinki are really good. Here's the current Python one:

And there's their web dev course, called Full Stack Open:

If learning web dev, you can't go wrong with The Odin Project:

Dan Grossman’s Programming Language series on Coursera is one of the best courses I’ve taken at any level of education

For guitarists, Paul Davids’ courses through his website are excellent

Hastie and Tibshirani's class on Statistical Learning is a must for someone that wants to learn about ML. All of the classes are available here (https://www.youtube.com/playlist?list=PLoROMvodv4rOzrYsAxzQy...) and the book recently got a Python version to complement the original R classes.

Very fun watching this guy chat about probability.

Statistics 110 Probability: https://projects.iq.harvard.edu/stat110/youtube

And this guy (Erik Demaine) is an absolute gem for introductory algorithms.

Introduction to Algorithms: https://ocw.mit.edu/courses/6-006-introduction-to-algorithms...

edX had some absolutely amazing free courses that still is a part of me. They were really tough though

Big list of free programming books:

FastAI’s course seems good so far

I can thoroughly recommend Execute Program [0] by Destroy All Software
