1. Driver Development: Errors Shadow Us In the field of C++ device driver development, error handling and exception management are like a hidden “shadow” that constantly affects the quality and stability of the driver program. When we eagerly expect the device to run smoothly, but encounter issues like the device not being recognized or data … Read more
1.The Importance of Driver Loading Loading drivers is the cornerstone of normal device operation. Take a graphics card as an example: when we install a new graphics card on a computer, if we do not load the corresponding driver, the operating system will not be able to recognize the various functions of the graphics card. … Read more
1. Interrupts: The “Emergency Contact” Between Devices and Processors In the complex operation of computer systems, interrupts are a crucial technology. Simply put, an interrupt is when the computer pauses the currently running program to execute a related service program upon encountering an urgent event that needs to be processed. Once completed, it automatically returns … Read more
Device Driver – The “Translator” Between Hardware and Software In the world of computers, hardware is like human limbs, responsible for executing various specific tasks; software acts like the human brain, issuing commands and processing data. The device driver is the crucial bridge connecting hardware and the operating system, playing an essential “translating” role. Whenever … Read more
A few days ago, I saw in the envoy-wasm Slack group that a Google engineer, Yan, was discussing bringing Rust into Envoy.

Type Deduction and Auto Keyword in C++: Master Unknown Types In the world of C++ programming, type safety is a very important feature. However, sometimes manually specifying types can become cumbersome and error-prone when dealing with complex expressions or function return types. At this point, the auto keyword acts like a helpful assistant, helping us … Read more
Review of Basic Concepts of References A reference is essentially an alias for an existing variable. When we create a reference, we are essentially giving another name to a variable, and both point to the same memory address. For example: int num = 10; int& ref = num; Here, ref is a reference to num. … Read more
