　　Regular cleaning of dust in the computer The dust in the computer is apt to cause the parts to accelerate the aging, cause the hardware to run slow, even causes some to be unable to turn on normally because of the contact bad. For example, the fan, not in time to clean up easily cause the computer temperature is too high, it is easy to boot slow computer. So in order to time the dust in the computer, especially the desktop computer, should be

>/dev/nullNote:-j2 This option means that in the process of compiling, 2 jobs are derived simultaneously (when the CPU is doing time-consuming operations, the performance of multicore processors can be guaranteed to take full advantage) 16-core processors can derive 32 jobs simultaneously, i.e.-j32>/dev/null This option is used to process compilation information during compilation. This is configured to redirect useless information from the compilation process to a black hole with no return val

Classes that overwrite Auto-configuration Dynamic configuration with external properties "this article" Customizing the Error page "second article" The automatic configuration of Spring boot can save a lot of uninteresting configuration work, but not all automatic configuration can meet the requirements. For example, when you link a database, you need to use some or-mapping middleware, such as security-related configurations that require

The startup optimizations for Android are divided into three main parts:(1) bootloader optimization(2) Tailoring and optimization of Linux kernel(3) Tailoring and optimization of Android OS partsThis article focuses on the start-up optimization of the Android OS section, and the noteworthy optimization points are described below:1. Streamlining preload's classes and resourceAs described earlier, since all Android applications are forked from the zygote process, in order to share some class and r

We complete our example by creating a fully self-contained executable jar file that can be run in production env. An executable jar (sometimes called a "fat jars") is an archive file that contains the classes you compile and all the jar dependencies your code needs to run.This example continues on the basis of Spring Boot (1): Guide.(1) Add the following dependencies in Maven:1 can be punched into a runnable jar package -2 Build>3 Plug
