: "Programmers are said to have a dream to change the world: programming magic and full of power, countless young people join in, with dreams and thinking to change the world." "For us to have such a dream and to realize the joy and satisfaction in the realization of the dream, then no matter what the outcome, it should be a very happy thing."Due to the rigid requirements of the job, it is not free to choose the progress of reading. "Dream Broken Code" although read, but I think also will be in

and deserialization, PHP has two hook functions (hooks) __sleep () and __wakeup () for objects. Serialization is called before the __sleep, which can perform some cleanup work, such as closing the database connection, outputting unsaved persisted data, which returns an array of names of data members written to the byte stream, and if an empty array is returned, no data is written to the byte stream. The __wakeup () is called after deserialization, which can perform some initialization operation

. From here, the CPU is a series of operations that can be used to process processes.The creation of processes, the destruction of the state of communication between transitions between synchronous asynchronous concurrency and the scheduling of processes. The details are as follows:3.2 Memory 内存的主要作用就是给cpu提供数据，既然是内存那就避免不免的流程： 分配 回收 我们所有的操作也都时围绕这俩点进行的，说道内存的分配那就肯定分为俩中情况： 连续 非连续 类似于数据结构 的线性和非线性。 连续分配内存就是很简单了，就是分配连续的内存，但是分配多少呢，这就是一个问题了，所以就分为固定内存的分配 和动态内存的分配（根据程序，数据 大小），并且采用相关的分配算法。缺点：内存碎片化

The eighth chapter describes the types of software requirements, stakeholders, the common methods and steps to obtain user requirements, the framework of competitive demand analysis NABCD, four-quadrant approach, and the project planning and estimating techniques. Among them, software requirements are divided into: 1. Acquiring and guiding requirements2. Analyze and define Requirements3. Verification Requirements4. Managing requirements in the life cycle of software products The st

not allow you to really achieve the goal, but will certainly let you get closer to the target place.About reading and writingThe last and most important point is that the Zhou Yun teacher has repeatedly stressed the reading and writing, but also I think I did not do enough of the place. Reading is an important way to acquire knowledge, enrich personal connotation, and learn from others ' life to guide their own correct life, while writing is a process of recording and a process of helping to co
