Synchronous:How to distinguish between synchronous and asynchronous? A synchronous switching power supply has two MOSFETs, one is the switching transistor, and the other is the synchronous transistor. When the switching transistor is off, the synchronous transistor turns on to continue the current flow. Synchronous switching power supplies have higher efficiency. A switching power supply that … Read more

In today’s Internet of Things (IoT) era, the MQTT (Message Queuing Telemetry Transport) protocol has become one of the mainstream protocols for connecting various devices and systems. For .NET developers, choosing a high-performance, stable, and easy-to-use MQTT library is crucial. Today, we will recommend a high-performance .NET library—MQTTnet. Introduction to MQTTnet MQTTnet is an open-source … Read more
In high-performance computing fields, such as high-frequency trading (HFT), every nanosecond is crucial. A slight delay can lead to significant opportunity costs. Therefore, developers must scrutinize every aspect of their code to eliminate unnecessary performance overhead. Logging is essential for debugging and monitoring, but if implemented poorly, it can itself become a major performance bottleneck. … Read more
