The Linux IO model refers to the way in which user processes and the kernel perform input and output operations in a Linux system. Input and output operations usually involve the transmission and copying of data. These operations consume system resources and time. Therefore, choosing an appropriate IO model is very important to improve the […]

Class variables/methods, main syntax, code blocks
1. Class variables and methods Mind map overview: 1.1 Class variables (static variables) 1.What are class variables/methods? –Add the static keyword to modify the member properties or member methods in the class. Class variables/methods are also called static variables/methods. Static variables/methods are shared by all objects of the class itself. 2. A small case to […]
Blockchain development using Golang Web3 library
Introduction Blockchain, as a distributed ledger technology, has achieved tremendous development in recent years. Golang, as an efficient and highly concurrency programming language, is widely used in blockchain development. In Golang, we can use the Web3 library to interact with Ethereum or other blockchain networks. The Web3 library is a library of tools for interacting […]
