Don’t expect a dry-as-dust description of how to plug things in or where to find your serial number. And you certainly won’t learn how to create a spreadsheet or a presentation. That’s really not computer science, it’s something else entirely. [...] We’re not going to make odd-coloured goop, but we will use experiments to discover how to program a computer to create your own games and animations, how to make graphics appear on screen just by typing in the right code (just like the developers of your favourite games do), how to get a cat to do your maths homework for you, and much more. [...] And that’s your first step on the journey to becoming a real computer programmer, a games developer, an über-hacker just like in the movies (only cooler and staying strictly within the law) and many other things besides.
