Nice and short book that is written in tutorial style with lots of interesting details. It will teach you how to use Chef and Capistrano in a practical manner, starting with basics. Definitely a worth reading, even you know this stuff, you can find a few tricks to add to your arsenal.
Very similar with “Thinking, Fast and Slow” by Daniel Kahneman in a way that aims to provide insights about how human mind works and how that can be exploited on the road of product creation and innovation. Even if the former was a more deep reading on the subject, the comparisons with real-world products were good. Some real world (and very obvious) examples were provided (Twitter, Instagram, Snapchat) but that was expected.
I liked the fact that it spoke about Framing and Anchoring effects and if you get interest in that, definitely give a read to Kahneman's book. It is a masterpiece.
