This is an interesting thought. The interactivity and the implementation are actually as important or possibly more important than the book text.

This could lead to a dramatic shift in how technical books are created.

Imagine a new website that didn't offer videos or text or tutorials, but actually was integrated with all of those things together?

So in your case, the book can be read or listened to, as you work on the example implementations. Using a little ML, you could probably even offer suggestions to roadblocks.

Just got sidetracked on this thought.

I'm a DDD guy, but have never personally implemented CQRS and event streams. I love the idea of separate read and write streams, but what is the best mesh of tech to do it well? (rhetorical question)

I'll buy the eBook. Thanks for working on this.
