Netty's heartbeat Detection Technology (IV.)I. INTRODUCTION　　"Heartbeat" sounds like a bull x, but it's just a technique for detecting end-to-end connection state. To give a simple "chestnut", existing both ends of A and b are connected, but they have not had data interaction for a long time, so how can a and b determine if the connection is available? Our usual practice is to let either side, such as we let a end, timed send (for example every 5 seco

QT Mobile Application Development (IV): applying particle effectsThe previous article describes how QT quick supports frame animations. The realization of frame animation is inseparable from state machine, while state machine, animation and state switch (transitions) are the core content of QT framework. That is, they can be built in whatever graphical display module a Qobject object does not have to rely on QT. Take a sample to say it. Suppose you wa

Iv. Analysis of Hello,worldC language is a computer language oriented to process programming, and it mainly takes the method of function call to control the process. Process-oriented programming emphasizes modularity. Analyze the problems that need to be solved, find out the steps needed to solve the problem, and then use the function to implement the steps of solving the problem step by step, then call the function from the top down one by one.
