“Code is the new lingua franca.”Linda Liukas, author of the popular “Hello Ruby” book series, started writing because she thought storytelling was missing from computer science education. Although coding is an overarching theme in the books, her writing is not exclusively about coding. Linda has a great admiration for famous educators like Piaget, and she has a mission to prepare kids for a world where so many of the problems that they encounter are computer-related. She points out that computers are tools for self-expression and problem solving. In her opinion, computers are abstract machines and most of all, technology is built on humanity.
