You read that right, the aging compression algorithm—bzip2, which still exists in countless software dependency trees, has officially embraced Rust. In the latest release of bzip2 crate 0.6.0, it no longer calls the C library by default, but instead fully utilizes the Rust-implemented libbz2-rs-sys. This means: faster performance, simpler cross-compilation, stronger compatibility, and enhanced safety. … Read more
Of course! Arrays are one of the most fundamental and commonly used data structures in C language. Understanding the underlying principles of arrays not only helps you write efficient programs but also lays a solid foundation for learning pointers, memory management, and more. 1. What is an Array? An array is a group of contiguous … Read more
1. Set a specific bit to 1: Macro #define setbit(x,y) x|=(1<<y) – Sets the y-th bit to 1.2. Set a specific bit to 0: Macro #define clrbit(x,y) x&=~(1<<y) – Sets the y-th bit to 0.3. Toggle a specific bit: Macro #define reversebit(x,y) x^=(1<<y) – Toggles the y-th bit. Note: XOR results in 0 for the … Read more

Simple Factory Pattern The Simple Factory Pattern, also known as the Static Factory Method Pattern, is a type of creational pattern. It encapsulates the object creation logic through a factory class, dynamically instantiating specific product classes based on input parameters, achieving decoupling of creation and … Read more
When learning and using PID, there are many motor options available. However, the PID parameters used for different motors can vary significantly. Therefore, we need to understand motors and drivers. 1 Types of Motors 1.1 Introduction to Motors A motor is a device that can convert electrical energy into mechanical energy and vice versa. Generators … Read more
Today’s AI agents are capable of perceiving, making decisions, and taking actions independently. With the rise of large language model (LLM)-driven AI agents, we are on the brink of a new era: AI agents may form their own societies and coexist harmoniously with humans. Below, we will discuss what AI agents are, why they are … Read more
