I have been reading and searching (repeat) for Julia resources in the intermediate to advanced range but also materials covering things like Julia internals.
I heard about this youtube channel while listening to the Talk Julia podcast, Julia for Talented Amateurs, which appears to cover a range of topics. I’ve watched about four videos so far and they were very well done. It is strange that in all my youtube-ing I never stumbled across this channel.
Anyway - I am posting it here to share since others may also find it useful.
