Hi together, Today I was looking for some (almost) scientific sources (pdf, articles, ...) that give an insight what really happens behind the scenes and that explains the technical details of Ruby; how does Ruby actually work?? Unfortunately I only found language references, how to code guides and alike. Nothing that states what is really happening with my piece of code when I call 'ruby myfile.rb' If you guys know some sources of such pdfs, books, articles, please let me know.
