web|web2| Security Developers must weigh the relationship between security and functionality to see how likely an attack is to succeed and how important the system is. Developers can use many basic principles to enhance the security of Web applications. The following three principles are mainly: 　　Minimize permissions When configuring an account that accesses resources, always limit the permissions on those accounts to the minimum permissions that are

The generated Android application APK file is best optimized because the essence of the APK package is a zip-compressed document that optimizes the orderly arrangement of uncompressed data in the package, reducing the memory consumption at the time the application runs. We can use the Zipalign tool for APK optimization. Zipalign is an important tool for optimizing APK applications, according to the Android official website. Most software developers

Tips for freeing drive space on your computer. You need to touch the input hardware to experience the touch features in Windows 8.1. For more information, see Multitouch hardware requirements. Can I keep my files, settings, and applications? If you start your computer from an installation media (such as a DVD or U disk) that you created when you download ISO, you will not be able to keep your application, Windows, settings, or personal files when

SummaryThis paper enumerates several representative applications of triggers: Data dispersion-centralized model design, historical data export, data interface between application systems. And how to design these triggers are discussed. 　　 Key WordsTriggers, data dispersion-centralized model, historical data export, data interface 1 IntroductionTriggers are often used in large database designs. It is characterized by: once defined, it exists in the b

In our previous article, "Using the platform interface provided by Ubuntu-app-platform to reduce QT application Size", we have learned how to use platform interface to reduce the size of QT applications. The implementation of this principle is to use content sharing to achieve. In today's tutorial, we use a Python interpreter snap installation package developed by developers themselves to achieve the same thing. For some systems, if you want to use th

Ajax| Program | error SummaryWhen some applications crash, they often give the user an opportunity to submit information about the error. This information can help developers track and fix bugs. This article will show you how to implement this functionality in your Javascript/ajax application. 　　 first, the introduction If you can access the end user's computer, the end user's JavaScript error is easy to debug. Now that you can't do this, you can

Programs deploy applications in C # Deploying the project in Visual Studio.NET is simple. Most programs can be done automatically with some handy wizards, without any effort.

This topic lists the URI schemes that you can use to start a built-in application. Many applications that are built into Windows Phone can be started from your application by calling Launchuriasync (URI) and passing in a URI that uses the scheme associated with the application to start. For example, the following call can start the Bluetooth settings application. Windows.System.Launcher.LaunchUriAsync (New Uri ("Ms-settings-bluetooth:")); Both manag
