Usually I use Python for scientific computing, and find it good for machine learning, and I know some R/Stan which I find better for Bayesian statistics. I'm hoping Julia will be the best of both, but the homepage doesn't have great resources for getting started - any recommendations?

It's mostly problem-based. I hope that by showing you a manual, some resources I like to use, some problems, and then some high level discussions you can get up and working in no time. Sources for "how to write a function" can be found elsewhere: this resource starts assuming you can read a manual if you know what to search for.
(Note that there are some v1.0 updates still necessary, but most works)
