What is a closure? To put it simply, closures get different results based on different configuration information. Let's take a look at our professional explanation: closure is short for lexical closure, a function that references free variables.

Mutex lock is the simplest thread synchronization mechanism. The condition object provided by Python provides support for complex thread synchronization problems. Condition is called a condition variable. In addition to providing acquire and release

During the summer vacation, I didn't go home. I stayed at school to do a text message sending project. The conversion of Chinese characters and Unicode codes made me quite awkward. At the beginning, I started to use C language, and there was always

Some time ago, I made an article on porting qt4.6.3 to mini2440, and I have also reproduced it. I found that many problems have been encountered according to the above, and now I have recorded some of them,To avoid detours in the future.First, refer
