In actual work, the implementation of MySQL delayed backup bitsCN.com often happens when you accidentally delete the database or table and regret it. is there any regret? The delayed backup described today can be achieved.
Delayed backup causes slave to lag behind the master for a period of time. when a misoperation occurs, you only need to immediately stop slave synchronization, and you can easily retrieve the accidentally deleted data from the delayed backup database.

Figure 1 makefile structure of Android
Android compilation files mainly depend on MK files. The source code compilation name is Android. mk, which is not a common MAKEFILE file.
The MAKEFILE file in the android Directory includes the main. mk file in the build/Core directory.

The basic structure of makefile of u-boot1.3.2 is analyzed as follows:The main directory contains a makefile, a config. mk, and a mkconfig script.(1) first, the user needs makeSmdk2410_config, so that makefile will generate include/config. mk using the mkconfig script.Arch, board, CPU, Soc, and other variables can be used by other makefiles as a basic configuration.MakeSmdk2410_config, so include/config.

The following is a problem with the HDU server code. the maximum time for each submission is 765 ms or a small value.
Of course, it can be further optimized. For example, bit operation processing may take more than twice as long as it is too time-consuming to write.

Android Compilation System Analysis
Since the android open source, it has aroused a boom in the embedded industry. Many embedded developers expressed strong interest in Android and downloaded the android source code for compilation and transplantation. The huge Android source code (repo down, about 2 GB) gives people the illusion that android is quite complex. From the android compiling system perspective, this article shows you that android is actually pure.
