I'm not sure if this is meant for absolutely complete beginners, or if it's tongue-in-cheek.

#5, #4, #2 are general ignorance of Unix-like systems. (being unaware of password prompts of obscuring input, or in more technical terms setting /dev/tty to raw... really?)

#3: "But the one thing you can't write in the text editor? Unix commands!" To be pedantic, that's shell scripting.

#1 is basically a build-up for an ad.

In all cases, little of this is directly related to Rails.
