Hi there! Thanks for you feedback and questions 
- p.75, Ch 1, §“Handle Events”: “Finally, we return a tuple in the shape that LiveView expects—{:ok, socket}.” For
handle_eventI think the tuple has to be{:no_reply, socket}or{:reply, socket}?
You are correct! You’ll find this updated in the next Beta release 
- p.98, P 1 Ch 2, §“Reducers in Plug”: The second representation of the pipeline using pipe operators still has
plugin the last three lines, but I think shouldn’t?
Yes I think this example will be more clear with the change you are suggesting. You’ll find it in the next release!
p.71, Ch 1, § “Render the Live View”: Just wondering, since the links you’re rendering go nowhere, if the semantics here aren’t better represented by
<buttons>? And similarly the<h2>tag could be replaced by an ordered list?
Great suggestions and I think if I was building a “real” game, cleaning up the code in that way would be the way to go. But the current approach will suffice for this example
