One of the reasons I love Hartl's Rails Tutorial <https://www.railstutorial.org/book> https://www.railstutorial.org/book> is because he integrated a completely free c9.io account which (with the commands he gives you) is guaranteed to setup Rails and a shell environment identical to what the book expects. I have seen so many aspiring programmers stymied by things like installing a text editor, let alone the right version of Ruby or incompatible gems. And, people with less money are more likely to have a cheap Windows laptop, which makes configuration even more difficult. By contrast, anyone with a computer or even an Internet cafe should be able to get an up-to-date browser, and c9 is plenty good enough for getting started. I've started taking my 9-year-old son through the book, and though it's crazy how large a vocabulary you need if you really wanted to understand everything, that's not actually necessary and he's able to follow the directions and make progress.
