💥 It is said that Rust bids farewell to segmentation faults forever, yet I encountered a <span>cargo build</span> crash with SIGSEGV just 3 seconds later.Memory safety? Yes, but it only guarantees “safety” without ensuring “correctness”.Today, this post will dissect the three UB monsters I created with Rust, along with a troubleshooting toolbox, which I recommend … Read more
In embedded development, have you ever encountered the following issues: The speed mismatch between data producers (e.g., sensor acquisition) and consumers (e.g., data processing threads) Using a single buffer leads to read-write conflicts that cause data corruption Frequent memory copies result in low CPU efficiency Data loss issues are difficult to resolve completely Today, I … Read more
C++ multithreading programming has always been a highly technical topic. It can bring significant performance improvements, but improper handling of details can lead to serious issues. With the popularity of multi-core processors, many developers choose to introduce multithreading to optimize program performance when facing compute-intensive tasks. However, C++ multithreading programming is not as simple as … Read more
In multithreaded programming, there are two issues to pay attention to: one is data races, and the other is memory execution order. What is a data race? First, let’s look at what a data race is and what problems it can cause. #include <iostream> #include <thread> int counter = 0; void increment() { for (int … Read more

Multithreading Interview: Interview Questions on Thread Synchronization and Communication in C In multithreaded programming, thread synchronization and communication are very important topics. These concepts not only help programmers avoid data conflicts but also ensure effective collaboration between multiple threads. This article will explain these fundamental concepts in detail and demonstrate their implementation in C language … Read more
