some of the best practices from extreme programming, including should red programming,Status meeting, quick iteration and test driven programming.The progress that the team employs XP has shown certain strength as well as weaknesses. Each will be describedBelow.Strength:
Specified red programming boosts up performance.The team starts with barely any experience on the Android platform. By requiring members to work in pairs onSame functionality, members cocould be learning much quickly. working a

The records used to process the summary c-find. "Problem": However, there is a serious problem with local testing, and each time listpending returns a random result format. So what is causing the problem? Let's see if the listpending () function is capable of

For the development of Small embedded systems, you may not think of the "file" level. In fact, the file here does not fully refer to the Unit for storing data. It can be a device, such as a display, keyboard, serial port input and output. These devices can all be used as files. We only need to distinguish different files by file, and we can collect the corresponding output input mode for different files. In this way, file makes my extended space larger.
