Development and Optimization of Embedded Systems Hey, C++ friends, today Hui Xiaoqin wants to talk to you about the application of C++ in the Internet of Things (IoT), especially in the development and optimization of embedded systems. The IoT is like a giant network connecting various devices and sensors, and embedded systems are the brains … Read more
Writing embedded systems is indeed an interesting task. Unlike regular application development, we have to deal directly with the hardware and also worry about memory usage and real-time performance. As a veteran in embedded systems for over a decade, I find that developing embedded systems with C++ is quite cool. It allows us to utilize … Read more
C++ and Embedded Systems: Core Technologies for IoT Device Development Hello everyone, I’m Xiao Shao. Today, let’s talk about a very practical knowledge point in C++—smart pointers. In the world of C++, smart pointers are like our capable assistants in managing memory. They help us automatically manage memory, avoid memory leaks, and make our code … Read more
Introduction I have been researching IO for a long time and have been unable to connect bio and block device drivers. I only knew that bio is passed to the block device driver through the IO scheduling algorithm, but I never fully understood how this happens or where the IO scheduling algorithm plays its role. … Read more
Set Script Home as “Starred⭐” Receive article updates in real-time Source: Rust Development Notes (ID: gh_8009fefbaa0f) In the current programming world, Python is widely accepted by developers, and it goes without saying.

C++ exception handling is one of the important features for improving program robustness and maintainability. In C++, resource management is closely related to exception handling, especially in ensuring that resources are correctly released in the event of an exception. In this regard, RAII (Resource Acquisition Is Initialization) is a very important design pattern that uses … Read more
Hello everyone! Today we will explore a very important C++ concept—smart pointers. As a beginner, you may encounter memory management issues during your learning process. Smart pointers were created to solve these problems; they help us manage memory better and avoid those pesky memory leaks. Next, I will guide you step by step to understand … Read more
Pointers are extremely important in C. However, to fully understand pointers, one must not only have a proficient grasp of the C language but also basic knowledge of computer hardware and operating systems. Therefore, this article aims to explain pointers comprehensively. Why Use Pointers? Pointers solve some fundamental problems in programming. First, using pointers allows … Read more
