Ruby Wizardry

February 15, 2015
An introductory programming guide is structured around a whimsical original fairy tale in a land run on the Ruby programming language.Weinstein turns his professional programming expertise and his experience as a computing educator designing curriculum for Codeacademy to creating an accessible introduction to coding for kids. The first chapter gives instructions on downloading and installing Ruby, as well as when to program "in window" and when to use a text editor. For an optimal experience, readers should read it while at a computer, inputting the suggested code and playing with it alongside the characters. The story stars young Ruby wizards Scarlet and Ruben, who find a king in great distress. After solving his problem, they notice more mishaps in the code that runs the kingdom. Deducing sabotage, they must travel the kingdom reprogramming code to correct errors and apprehend the guilty party. An episodic structure makes the book easy to put down and pick up again (as it's a lot of information for one sitting), and chapters frequently end with "You Know This!" recaps. Comprehensive backmatter includes further resources, troubleshooting and more. After completing their introduction to Ruby, readers can move onto Nick Morgan's JavaScript for Kids (2014), which, though it doesn't present a narrative such as this, is an absolutely phenomenal guide with a crisp design and clear, concise explanations. An enjoyable book that can turn any kid (or adult!) into a programming wizard. (index) (Nonfiction/fantasy. 10 & up)
