The most taboo thing for learning any science knowledge is to cram various academic jargon and formulas, that's why almost any school textbooks with text-heavy approach always make us feel drowsy! Because when explaining those obscure and complicated knowledge points, they are not clear and readable enough to make us understand and absorb these knowledge points with ease and efficiency.

The Rails framework (formerly the MVC framework, AKA: Ruby on Rails) was put forward by David Heinemeier Hansson from Denmark for the first time in 2004. Different from any existing complex, ivory-towered Web development frameworks at that time, Rails is more in line with actual needs and more efficient. It combines the advantages of PHP system (rapid development) and Java system (structured programming). As a consequence, Rails received extensive attention in the industry not long after it was proposed.

For knowledge placing emphasis on the theory, only books like the Head First series that focuses on the cognitive science and learning theory can bring us multi-sensory and light learning experience, so as to avoid using too much text to make readers feel drowsy and harvest little just like most textbooks.

Maybe you ever found that too many computer network related books are full of boring text and web terms that let a reader feel tired and sleepy, which is the biggest obstacle for many beginners who want to learn the network technology. Then try the Head First Networking instead.

Head First Object-Oriented Analysis & Design (short for Head First OOA&D) will tell you how to analyze, design and write a truly object-oriented software, which is easy to reuse, simple to maintain and extensible anytime. That's one software will no longer break your heart and allows you to add new features without breaking the old mechanisms.
