This is really inspiring! I had no idea that Linda co-founded Rails Girls, and for some reason I had formed the impression that she was an illustrator before becoming a programmer. I didn't know that she had learned to draw so that she could create the book. This advice is golden, and it's pretty cool to see such joy, enthusiasm, and generosity rewarded.
Makes me think that maybe I could write the code equivalent of "Scary Stories to Tell in the Dark" using Java
Most startups have a coding conventions guide for new hires -- and in my experience, it's a dry and tedious thing to study.
It would be funny and interesting to engage new programmers with animated horror stories instead of just: "Braces go on the next line...and please sanitize your data."
