For non C-programmer, it is difficult to take his/her first step toward reading implementation of Ruby interpreter. I’m now trying to read it. At the last the last Rubyconf.tw 2014, I talked about ""how to take the first step"", titled ""walking-around-the-ruby-forest"": introduced the books for reference, glanced Ruby source files, and showed basic ruby data-structure. https://speakerdeck.com/yotii23/walking-around-the-ruby-forest. In RubyKaigi 2014, I’ll talk about one more step, more detailed Ruby Implementation.
