Justin Weiss is a Rails developer who writes about Ruby and Rails techniques and wrote the book Practicing Rails.
HN links it for its monkey-patching post as an example of Ruby culture. The author says he writes for people who struggle to build with Rails.
I've been writing posts about Rails on http://www.justinweiss.com for a little over a year now, and I've heard from so many people that are excited about Rails, that have bought all kinds of videos and tutorials and courses and bootcamps, but just can't build their own projects.
So, I wrote a book to help. It's not so much a Rails tutorial as it is a guide to programming, project management, and motivation, using Rails as a medium.
I'm happy to answer any questions you have!
Ruby has a culture around it too: https://www.justinweiss.com/articles/3-ways-to-monkey-patch-without-making-a-mess/
And you can get some of the patching effect in any language with uniform function/method calls, though typically with a little more scoping and thus less ability to inflict unexpected side effects: https://en.wikipedia.org/wiki/Uniform_Function_Call_Syntax
