This is only tangentially related, but is https://poignant.guide/ https://poignant.guide/ missing some chapters? Chapter 3^ says (among other things) > Two chapters from now you'll be writing your own Ruby programs. In fact, it's right about there that I'll have you start writing your own role-playing game, your own file-sharing network (a la BitTorrent), as well as a program that will pull genuine random numbers from the Internet. Which always sounded cool to me (and still does), but it's never brought up again in the book. Were those meant (and I realize no one can say for sure) merely as examples of projects one could do, or did (a version of) the book walk you through their implementations? Or am I missing something? ^ https://poignant.guide/book/chapter-3.html https://poignant.guide/book/chapter-3.html
