Foreword (1) In embedded programming, we often need to store data from various sensors. Most of the time sensors, such as infrared light sensors, return data that is either 0 or 1. Therefore, only one bit is needed to store it. However, many people often use char array storage, so that only one-eighth of the […]

State pattern – object states and their transitions
In a certain credit card business system, bank accounts have three states, and there are different behaviors in different states: 1) Normal state (balance is greater than 0), users can deposit or withdraw money; 2) Overdraft status (the balance is less than 0 and greater than -2000), the user can deposit or withdraw money, but […]

Deep approximation of molecular dynamics: Superconducting quantum computers have been shown to be able to effectively predict two- or three-dimensional molecular dynamics states, bringing new research into quantum computing.
Author: Zen and the Art of Computer Programming 1. Introduction In the past few decades, the field of scientific research has entered a new period of development due to enhanced computing power, major breakthroughs in bioinformatics, and new discoveries in physics. Humanity’s understanding of the world has evolved from simple “life” to complex molecular systems. […]
Quantum entangled states in quantum computing – building new communication methods
Author: Zen and the Art of Computer Programming 1. Introduction 1.1 Purpose of writing This article aims to elaborate on the construction methods, principles, applications and prospects of quantum entangled states, an emerging communication mode in the field of quantum computing. By elaborating on the characteristics, composition and assembly process of quantum entangled states, it […]
Conditional race coverage for temporary intermediate states of objects
Conditional Competition at Portswigger Training Ground Conditional competition for temporary intermediate states of objects Lab: Partial construction race conditions Necessary knowledge points before experiment Some frameworks try to prevent accidental data corruption by using some form of request locking. For example, PHP’s native session handler module handles only one request per session at a time. […]

Python uses matplotlib dynamic drawing to realize the comparative trend of GDP between China and the United States over the years.
As China’s various strengths improve, we often see comparisons of various indicator data between China and various countries over the years in various media. In order to more clearly display the development trends over the years, some even make animated graphics. Seeing China’s continuous counterattacks in various indicator data in recent years, I feel proud […]
