Hello!
I recently started picking up Bayesian modelling and PyMC3 and picked up a lot of great tips and tricks. I kept a blog post updated with everything I’ve learnt from @twiecki and @aseyboldt in the past two weeks. I’ve more or less stopped updating the blog post, since I’m starting to learn very niche or model-specific things that aren’t really the main concern of a beginner (although I’m not sure if this means I’ve graduated from being a beginner… 
)
I thought I’d just share this, in case someone here finds it to be a useful resource. Enjoy!
