Article Introduction：Nested Generic Functions Generic functions in Go 1.18 allow the creation of functions that apply to multiple types, and nested generic functions can create reusable code hierarchies: Generic functions can be nested within each other, creating a nested code reuse structure. By composing filters and mapping functions into a pipeline, you can create reusable type-safe pipelines. Nested generic functions provide a powerful tool for creating reusable, type-safe code, making your code more efficient and maintainable.

Article Introduction：The Linux architecture is shown in the figure below. The Linux architecture can be broadly divided into user space (UserSpace) and kernel space (KernelSpace). User space includes C libraries and user applications. Some architecture diagrams also include shells. Of course, shell scripts are also an integral part of the Linux system. Kernel space includes hardware platform, platform dependent code, kernel and system call interface. In any modern operating system, there are layers. Why is layering necessary? From a programmer's perspective, separating the Linux underlying and applications allows each to focus on its own area, thereby improving efficiency. From a security perspective, layering is about protecting the internal

Article Introduction：In software development, version control is a very important link. Git is one of the most popular distributed version control systems currently. Git has many configuration options, including global configuration, warehouse-level configuration, local branch-level configuration, remote branch-level configuration, etc. So, at which level should Git be configured? First, we need to understand Git's configuration hierarchy. Git configuration is divided into three levels: system level, global user level and warehouse level. System-level configuration takes effect for all users and repositories using Git, including those installed on the machine.

Article Introduction：Vue (pronounced /vjuː/, similar to view) is a progressive framework for building user interfaces. Unlike other large frameworks, Vue is designed to be applied layer by layer from the bottom up. Vue's core library only focuses on the view layer, which is not only easy to get started, but also easy to integrate with third-party libraries or existing projects. On the other hand, when combined with a modern tool chain and various supporting libraries, Vue is fully capable of providing drivers for complex single-page applications.

Article Introduction：What is SQLC SQLC is a powerful development tool whose core function is to convert SQL queries into type-safe Go code. By parsing SQL statements and analyzing database structures, sqlc can automatically generate corresponding Go structures and functions, greatly simplifying the code writing process for database operations. Using sqlc, developers can focus on writing SQL queries and leave the tedious Go code generation work to the tool, thus accelerating the development process and improving code quality. SQLC transaction implementation The code generated by Sqlc usually contains a Queries structure, which encapsulates all database operations. This structure implements a pass

Article Introduction：The function library is not the PHP syntax for defining functions, but a design pattern in programming. Functions are modules of structured programming and are the core of code reuse. In order to better organize the code, custom functions can be used in multiple files in the same project.

Article Introduction：Introduction to PHPSPL Data Structure Library The PHP Standard Library (SPL) contains a rich set of built-in data types called data structures. These structures provide efficient and flexible management of complex data collections. Using SPL data structures can bring the following benefits to your application: Performance Optimization: SPL data structures are specifically designed to provide optimal performance in a variety of situations. Improved maintainability: These structures simplify the handling of complex data types, thereby improving code readability and maintainability. Standardization: SPL data structures conform to PHP programming specifications, ensuring consistency and interoperability across applications. SPL Data Structure Types SPL provides several data structure types, each with its own unique characteristics and uses: Stack (St

Article Introduction：The choice of the best C++ container library container depends on the application requirements. The STL container library provides common data structures, while the Boost container library extends STL. Third-party container libraries (such as EASTL, Folly, and Abseil) provide containers designed for specific needs. When choosing a container, consider data types, required operations, performance, memory footprint, and thread safety.

Article Introduction：Code refactoring is key to PHP application performance optimization and involves changing existing code to improve performance. Practical strategies include caching query results to avoid repeated database queries. Function decomposition breaks large functions into smaller modules. Duplicate code elimination uses functions or loops to eliminate redundant code. Use data structures to organize data to improve access efficiency. Reduce branch judgments and use switch-case or if-else statements to optimize nested if-else chains. Optimize database queries using indexes, restricted result sets, and cached queries.
