Ask HN: Learn Distributed Systems Interactively

Hi HN,

TLDR: What are the interactive tools to learn distributed systems?

I have been trying to learn distributed systems by reading papers, blogs, and open-source docs. Every time it feels I haven't grokked the fundamental concepts.

For no particular reasons, I have failed finish any book or complete an online courses on the topic.

So, I want to explore different approach to learn. For example, a visual or interactive tool like pythontutor.com

Thanks
