You have successfully built an excellent IoT system: device data transmission is stable and smooth, and the real-time dashboard is functioning well. However, once asynchronous operations are involved, problems arise: critical firmware updates sent to offline smart locks fail; data processing nodes experience load imbalance, with some nodes idle while others are overwhelmed. The real-time … Read more
Have you ever experienced two processes frantically competing to read and write data, resulting in either fragmented data or the program getting stuck in “synchronization wait”?It’s like a cafeteria where no one is in line, everyone is pushing at the window, and in the end, the food spills, and no one gets to eat well. … Read more
Changing a sensor requires modifying 100 lines of code? This article teaches you three methods to completely solve the module coupling problem. 1. Have You Encountered These Problems? As an embedded engineer, the most painful experiences include: 🔥 Hardware Change Nightmare: The project needs to replace the DHT11 temperature and humidity sensor with the SHT30, … Read more
In this data-driven era, message queues have become the “nervous system” of modern application architecture. From microservices communication to real-time data stream processing, from IoT devices to AI systems, message queues are ubiquitous. However, with the exponential growth of business complexity, traditional message queues are facing unprecedented challenges. It is time to rethink this field … Read more
In the development of microservices architecture and distributed systems, message queues are an indispensable component. As a lightweight and high-performance message middleware, NATS has been widely used in many projects. For C++ developers, using a NATS client library is a key aspect of connecting systems. Today, I would like to recommend a very powerful C++ … Read more
