The physical world exists objectively, while the human "visual imaging" is the "idealism" reconstruction of the current world. This reconstruction is based on personal "experience", "perception" and "collective consciousness". At first, scientists believed that human beings created a personal Visual database by visually passively acquiring all the image information of the world around them, and that nearly 10 years of research have shown that capturin
modified the class it belongs to.Strategy: Define a series of algorithms, encapsulate them one by one, and make them interchangeable with each other. This mode allows the algorithm to be changed independently of the customer using it.Templatemethod: Defines the skeleton of an algorithm in an operation, and delays some steps into subclasses. Templatemethod allows subclasses to redefine some specific steps of the algorithm without altering the structure of an algorithm.Visitor: Represents an oper
Article Description: the design and research of gesture operation used in mobile terminals are discussed.
Gesture refers to a system of language that is built up by a human language center with the position and shape of the palm and finger.

Three, in-depth rddThe Rdd itself is an abstract class with many specific implementations of subclasses:
The RDD will be calculated based on partition:
The default partitioner is as follows:
The documentation for Hashpartitioner is described below:
Another common type of partitioner is Rangepartitioner:
The RDD needs to consider the memory policy in the persistence:
Spark offers many storagelevel to choose from:

"Design Mode" (GOF): Not recommended for beginners to see. These four are PhD levels, they are the first to propose design patterns, high theoretical level, although a thin one, but the text is relatively obscure, but also lack of easy to understand examples. When you get to a certain level, if you are interested, you can look at it."Head First design mode": Good

I recently published an article in Jakob Nielsen's Alertbox article, which mentions a method of "measuring beauty", and many people let me talk more about "consensual research". Consensual research is not just about measurement, because we can also use them to inform or enlighten you about the direction of different visual designs that you might be considering. In this article I refer to a metho
