In modern enterprises, especially in technology-driven companies, C++ plays a crucial role as an efficient and flexible programming language in software development, game development, and system programming. Therefore, effective human resource planning is essential for ensuring the success of the team. This article will explore how to assess the demand for C++ talent and develop … Read more
When programming in C++ under the Linux environment, multithreading provides excellent concurrency capabilities, allowing programs to perform more efficiently when handling complex tasks. However, multithreaded programming is not without its challenges; deadlock issues lurk like hidden “killers,” potentially causing programs to become stuck. Once a deadlock occurs, the program is trapped in an unbreakable loop, … Read more
If you are a long-time Python user, you are certainly familiar with the term “performance bottleneck.” Issues like ineffective multithreading, low efficiency in heavy computations, and relying on C extension packages to barely maintain performance often lead to both love and frustration. However, the emergence of Codon may truly address these longstanding challenges. Codon is … Read more
In modern computing, multithreaded programming is a common technique that allows programs to execute multiple tasks simultaneously, thereby improving efficiency and responsiveness. In C, we can use the POSIX Threads (pthread) library to implement multithreaded programming. This article will introduce the fundamentals of multithreading in C and demonstrate with example code. 1. What is Multithreading? … Read more
Thread Synchronization and Mutex Mechanisms in C Language In multithreaded programming, multiple threads may access shared resources simultaneously, which can lead to data inconsistency and unpredictable program behavior. To avoid these issues, we need to use thread synchronization and mutex mechanisms. This article will detail several commonly used synchronization and mutex mechanisms in C language, … Read more
In C, a signal is an asynchronous event used to notify a program that a certain condition has occurred. Signals can be generated by the operating system, hardware, or the program itself. Common signals include process termination and illegal memory access. In this article, we will introduce how to capture and handle these signals in … Read more

Implementing Multiprocessing in C: Process Creation and Management In modern operating systems, multiprocessing is a common technique that allows programs to execute multiple tasks simultaneously. The C language provides robust support for implementing multiprocessing, primarily through the <span>fork()</span> system call to create new processes. This article will detail how to implement multiprocessing in C, including … Read more

The C language provides robust multithreading support through the POSIX threads (pthread) library. This article will detail how to create and manage threads in C, as well as how to synchronize them. 1. … Read more
This article is a lab note for Lab7 of the MIT6.S081 Operating Systems course. The task is to simulate kernel process switching by implementing a user-level thread switching functionality. Additionally, I will introduce how xv6 achieves process switching by examining the source code. Lab7 address: https://pdos.csail.mit.edu/6.828/2020/labs/thread.html My lab records: https://github.com/yibaoshan/xv6-labs-2020/tree/thread Before starting the experiment, you … Read more
