Course Introduction：Personalized customization of VSCode welcome pages can be achieved by installing extensions and custom configurations. 1. Install extensions such as "CustomWelcomePage", edit the index.html and style files it generates, and insert HTML, CSS or JS to change the content of the welcome page; 2. Use the "CustomizeUI" class plug-in to inject custom CSS/JS, and achieve deeper appearance control by hiding original elements or dynamically generating new content; 3. Modify startup parameters such as code--new-window or specified path, and combine with the local server to open the custom page by default. Although VSCode itself does not support it directly

Course Introduction：Summary of key points Server-side rendering of React code helps reduce loading times and improve SEO flexibility, but handling asynchronous APIs can be challenging because of the need to render the application before knowing the required data. Existing solutions, such as Next.js, Redux Connect, and react-frontload, have their own advantages and disadvantages when dealing with asynchronous APIs in server- rendered React code. A custom solution can be implemented by performing two server-side renderings: the first time handles API calls and asynchronous operations, and the second time, the second time, the final page rendering is performed using the acquired data. Custom solutions require careful handling of different shapes in components

Course Introduction：Measuring thread performance in C can use the timing tools, performance analysis tools, and custom timers in the standard library. 1. Use the library to measure execution time. 2. Use gprof for performance analysis. The steps include adding the -pg option during compilation, running the program to generate a gmon.out file, and generating a performance report. 3. Use Valgrind's Callgrind module to perform more detailed analysis. The steps include running the program to generate the callgrind.out file and viewing the results using kcachegrind. 4. Custom timers can flexibly measure the execution time of a specific code segment. These methods help to fully understand thread performance and optimize code.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
