Check out the Julia for Data Science YouTube series that’s on the official Julia channel. A link to the first video in the series is here.
Check out mybinder.org for making your notebooks fully executable in the browser, without the user having to download anything. I created a very basic, intro to Julia notebook (specifically for colleagues of mine) that I have running on Binder so you can see what that looks like here: https://mybinder.org/v2/gh/mthelm85/Intro-to-Julia/master
I’ve been very frustrated at the lack of good data analysis/data science content on the web that relies on Julia. There are loads of great courses on a variety of online learning sites that make use of R/Python but almost nothing for Julia. I would be happy to contribute to this project and would be interested in linking up with you to share thoughts/organize an outline for topics to cover.
