Python Metaclasses Deep Dive
Article Introduction：Metaclass is a "template" of a class, used to control how classes are created, suitable for scenarios where framework design or large number of custom class behaviors are performed. It customizes the generation logic of the class by inheriting the type and rewriting the new or init methods. Common uses include automatic registration of subclasses, unified interface constraints, dynamic modification of class attributes, realizing singleton mode and ORM framework design, etc. When using it, you need to pay attention to avoid abuse, high debugging complexity, unintuitive reading order, and compatibility issues. Simple needs can be replaced by decorators.

How to build a web application with Flask in Python
Article Introduction：To build a FlaskWeb application, first set up the environment and install Flask, then create the basic application to return HTML content, then use the template to separate the logic and interface, add multi-page routing, process user input through forms, and introduce static files such as CSS for style design. Finally, it can expand the functions of database, user authentication, and other functions and deploy them online. The whole process is simple, flexible and easy to expand.

What is the Curiously Recurring Template Pattern (CRTP) in C ?
Article Introduction：CRTP is a C static polymorphic design pattern, with its core being the inheritance of the derived class itself of the base class template parameter. 1. The definition method is that the base class uses a template to accept the derived class as a parameter, and the derived class then inherits the base class instance; 2. Its advantage lies in the analysis method call during compilation to avoid the overhead of running virtual functions; 3. It is often used in static polymorphism, code reuse, interface uniformity and mixed behavior scenarios; 4. When using it, you need to pay attention to the correctness of type delivery, lack of dynamic binding, increased debugging complexity and possible code bloating problems.

How to style selection highlighting (`::selection`)?
Article Introduction：Use the ::selection pseudo-element of CSS to customize the highlighting style when the web page text is selected to improve the aesthetics and unity of the page. 1. Basic settings: define background-color and color through ::selection, such as yellow background with dark gray fonts; specific elements such as p::selection can also be limited. 2. Compatibility processing: Add the -webkit- prefix to be compatible with Safari and mobile browsers, and the Firefox and Edge standards are well supported. 3. Pay attention to readability: Avoid excessive color contrast or too fancy, and should be coordinated with the overall design. For example, choose a soft blue base in dark mode to improve visual comfort. Reasonable use can enhance the texture of the interface, ignore details

How to create a color picker using an HTML input tag
Article Introduction：Use HTML to create color selectors, 1. Add the type="color" attribute to display the system color selection interface; 2. Set the default color through the value attribute, and it needs to be a 7-bit hexadecimal format such as #ff00000; 3. Use JavaScript's input event to obtain the selected color value in real time and use it to update styles or storage; 4. Common uses include theme customization, design tools and form options; 5. You can save user preferences in combination with CSS variables, real-time background updates and localStorage, and achieve full functions without additional libraries.

C tutorial for GUI development with Qt
Article Introduction：It is recommended to use C for graphical interface development. It is recommended to choose the Qt framework because it is powerful and has good cross-platform support; 1. When installing Qt, it is recommended to check the MinGW or MSVC compiler and corresponding version library files. Using QtCreator can simplify the development process; 2. Create the first GUI program to be implemented through the QtWidgetsApplication template, and use the .ui file to visualize the design interface; 3. Use signal and slot mechanisms (such as connect function or automatically generated slot function) to achieve control interaction, such as a button click to pop up a dialog box; 4. It is recommended to start with QtWidgets and gradually master QML, document examples, official tutorials and open source project structure.

Understanding the JavaScript Template Method Pattern
Article Introduction：The template method pattern is a behavioral design pattern that defines an algorithm framework in the base class and delays specific steps to the subclass implementation. It enhances code reuse and structural clarity by encapsulating fixed processes and allowing local customization. 1. The core idea is to define the algorithm skeleton and delay some steps to subclasses; 2. Define template methods and steps through the parent class in JavaScript, and subclasses inherit and rewrite specific methods to implement; 3. Applicable scenarios include multiple subclasses sharing logic but different details, keeping the algorithm structure stable and requiring flexible changes; 4. When using it, pay attention to avoid excessive dependence on inheritance, ensuring that the step naming is clear, and non-abstract steps can be directly implemented in the parent class, and beware of the runtime risks brought by JS lacking interface support.

What is Docker and what is its architecture?
Article Introduction：Docker is a platform that allows developers to build, run and manage applications in containers. Its core structure includes DockerEngine, mirroring and containers, client-server architecture, and namespace-based isolation mechanism. 1.DockerEngine is a core component, including a daemon running in the background (responsible for building images and running containers), a RESTAPI interface and a command line client (CLI). 2. Mirror is a static template that contains the application and its dependencies. The container is a running instance of the image. Multiple containers can originate from the same image, and the image is built through the Dockerfile. 3. Docker uses the client-server architecture, the CLI communicates with the daemon through the API, and can also connect to remote guards.

how to create a certificate in word
Article Introduction：The steps to create a professional certificate using Microsoft Word are as follows: 1. Use built-in templates to quickly create, enter "certificate" to search and select the appropriate template before editing the content; 2. Pay attention to the layout structure when customizing the design, including title, text, signature area, date and decorative elements; 3. Set the page layout, insert background watermarks, and align content with text boxes or tables; 4. Unify the font size, the title is recommended to be bolded by No. 24, and use No. 14-16 for the text; 5. Adjust the margin to about 2.5cm to avoid content congestion; 6. Use high-quality mode and 120g or more jams to improve the texture; 7. Use the email merge function to generate similar certificates in batches.

Design Patterns in Java for Enterprise Applications
Article Introduction：The most commonly used design patterns in enterprise-level Java applications include: 1. Creation mode: Singleton mode is used to ensure globally unique instances, such as log manager; factory method mode is used to decouple object creation, such as database connection creation; abstract factory mode is used to create object families, such as cross-platform UI components. 2. Structural mode: The proxy mode is used to control object access, such as remote calls and delayed loading; the adapter mode is used for interface conversion, such as integrated WeChat payment; the decorator mode is used for dynamic expansion functions, such as packaging of Java I/O streams. 3. Behavioral mode: Observer mode is used for status notification, such as event monitoring system; policy mode is used to encapsulate variable algorithms, such as different discount strategies; template method mode is used to define algorithm skeletons, such as order processing flow.
