Detailed explanation of multi-thread programming and Python multi-thread programming in python I. Introduction Multi-threaded programming technology can achieve code parallelism and optimize processing capabilities. At the same time, smaller division of functions can make the code more reusable. The threading and Queue modules in Python can be used to implement m

Summary of Socket network programming, socket network programming Currently, almost all C/C ++ background programs require network communication. There are two Implementation Methods: Using the underlying system socket or using the existing encapsulated network library. This article summarizes the two methods and introduces a lightweight network communication library ZeroMQ. 1. Basic Scoket

Summary of Python object-oriented programming knowledge points, python Object-Oriented Programming Preface If you have never been familiar with object-oriented programming languages before, you may need to first understand some basic features of object-oriented languages and form a basic object-oriented concept in your mind, this helps you learn Python object-ori

Common Vulnerabilities and code instances in PHP programming, and php programming vulnerability instances With the widespread use of PHP, some hackers do not want to bother themselves with PHP, and attacking through PHP program vulnerabilities is one of them. In this section, we will analyze the security of PHP in terms of global variables, remote files, file uploads, library files, Session files, data type

Seven Principles of object programming and seven principles of object programmingSeven Principles of object programming: 1. OCPFull name: "Open-Closed Principle" Open-Closed PrincipleNote: It is open to extensions and closed to modifications.Advantages: the system designed according to the OCP principle reduces the coupling between various parts of the program, and has good adaptability, flexibility, and st

Linux Network Programming: original socket programming and instance analysis (1) I. What can the original socket do? Generally, the programmer receives two types of sockets: (1) stream Socket (SOCK_STREAM): a connection-oriented Socket for connection-oriented TCP Service applications; (2) datagram Socket (SOCK_DGRAM): a connectionless Socket that corresponds to a connectionless UDP Service Application. Fro

I learned Web programming at the age of 22. I learned PHP and ASP. I am still a student. I learned the basics of these two languages and I think programming is really hard, I am not very interested in this aspect, but I am not disgusted with it and I like it a bit. how can I stick to it now? what are the good experiences of the heroes? congratulations, I have already found the direction (I learned Web

Today I suddenly thought of this topic. Some readers may not quite understand what I mean. Defense-based programming: What problems do customers ask. Attack programming: proactively detects problems. Some of these problems are performance optimization problems, and some are bugs that customers fail to discover. Solve the problem as soon as possible. Real Scenario: When a function was made, the developer tri

I have never thought about those software engineering ideas for a long time, nor have I ever thought about rigid and hard work. It is enough to bring and combine useful tools so that they can really do a good job. On the basis of doing well, try to extract useful things, try to improve and improve tools and methods, and strive to do better. I just searched for the words "Object-Oriented Programming, structured pro
