The dictionary defines elegance as "graceful and graceful in form", and "scientific precision and simplicity", and we believe that elegant design, at least in the interactive design, combines both of these two kinds of perfection. The flowing experience of interaction and the design form of simple and complex, bring to the user is each instantaneous perfect experience, can let you feel the whole interactio

of Application layerThere are also three methods: decomposing the pressure, reducing reliance and virtual data manipulation.The most important method of decomposition pressure is divided by function, and the level is scaled by load balance, and some of the specific techniques in the PPT are mentioned that we should discard most Java ee things, keep the application layer stateless, and use the cache as much as possible.The most important way to reduce dependencies is to divide the code into func

javascript| Script Recently on the Internet to see an article, said JavaScript = C+lisp, so think about the problem, since JavaScript contains some of the lisp of the lineage, then use JavaScript to implement a Lisp-like AI script what will it look like? As a "functional" language family, the LISt processing has conquered many researchers and enthusiasts with its simple and graceful style and concise and efficient structure since the birth date.

appearance and feelings are very simple and clear. hand-drawn style applications enable users to recall the basic sketch, allowing users to focus on the presentation of basic functions, instead of focusing on the product appearance details. At the same time, this appearance also forms the unique style of Balsamiq. 　　 　Recognition and personalization Hand-painted style brings a higher degree of recognition, allowing users to remember your product. For example, the new logo of the famous Code E

But those who have done real business projects must have realized that it is not a few more than 10 classes, usually hundreds of thousands of classes, and there is a complex association between them, the interaction between the objects they create is quite complex, and usually must follow a bunch of business rules, even if it is based on a relatively stable static class for analysis design
