Linux C++ Programming: A Detailed Tutorial on Using Shell + GDB to Diagnose Deadlocks

Linux C++ Programming: A Detailed Tutorial on Using Shell + GDB to Diagnose Deadlocks

1. Introduction In the process of writing projects, multithreading is often involved. Programming multithreaded applications usually involves issues of thread safety, which is why mutexes are often used to ensure thread safety. However, the use of mutexes can often lead to another problem: deadlocks. A deadlock, simply put, occurs when there are two shared resources, … Read more

Understanding the Destruction Order of Static Objects in C++

Understanding the Destruction Order of Static Objects in C++

In the vast world of C++ programming, the static keyword acts as a low-key yet crucial behind-the-scenes hero, widely used in variables, functions, and class members, playing an indispensable role. From modifying local variables to retain their state, to limiting the scope of functions, and to achieving shared class members, the presence of static is … Read more

The Guardian of Stable Program Operation: A Detailed Implementation of C++ Watchdog

The Guardian of Stable Program Operation: A Detailed Implementation of C++ Watchdog

In critical scenarios such as industrial control and server applications, the stable operation of programs directly relates to business continuity and system reliability. Imagine if a server program suddenly becomes unresponsive without anyone knowing; it could lead to severe consequences such as data loss and service interruption. Today, we will introduce the “Watchdog” technology, which … Read more

Semaphore Overview (C++)

Semaphore Overview (C++)

Semaphore is a very important synchronization mechanism in concurrent programming (multithreading/multiprocessing), used to control access to shared resources by multiple threads or processes, preventing issues such as race conditions, data inconsistency, or deadlocks. 1. What is a Semaphore? ✅ Definition: A semaphore is a synchronization tool used to control access to shared resources by multiple … Read more

Semaphore Special Topic (C)

Semaphore Special Topic (C)

A semaphore is a mechanism used for inter-process synchronization and mutual exclusion, widely applied in multithreaded programming and operating systems. Semaphores can control access to shared resources, ensuring that multiple processes or threads can orderly use these resources, avoiding race conditions. 1. What is a Semaphore? ✅ Definition: A semaphore is a synchronization mechanism used … Read more

Basics of Python Multithreading: From Thread to ThreadPoolExecutor

Basics of Python Multithreading: From Thread to ThreadPoolExecutor

1. What Can Multithreading Solve? First, we need to clarify a concept: Concurrency (ćč¶ć‘) ≠ Parallelism (ćč¶èĄŒ). Concurrency is “appearing to run simultaneously”. For example, when you listen to music while coding, your brain quickly switches between the two tasks, which is called concurrency. Parallelism is “actually running simultaneously”. This requires multiple CPU cores, just … Read more
