Course Introduction：Setting up a custom cache directory helps manage disk space and optimize system performance, and operations are not complicated. 1. Reasons include freeing system disk space, centrally managing data, and improving performance with faster storage; 2. Linux/macOS can be implemented by setting the XDG_CACHE_HOME environment variable, creating a new directory and modifying the shell configuration file and reloading it; 3. In Windows, you can change the cache path through application settings or command line parameters (such as Chrome's --disk-cache-dir), and some programs also support registry modification; 4. Specific programs such as Steam allow you to specify the cache location by adding library folders, and AndroidStudio, etc. can customize the path in the system settings.

Course Introduction：PHP iterator and generator: a powerful tool for efficient processing of large data sets Arrays and iterations are the cornerstone of any application. As we get new tools, the way we use arrays should also improve. For example, a generator is a new tool. At first we only have arrays, and then we gain the ability to define our own class array structure (called iterators). But since PHP 5.5, we can quickly create class iterator structures called generators. Generators look like functions, but we can use them as iterators. They provide us with a simple syntax for creating essentially interruptible, repeatable functions. They are amazing! We will look at several areas where generators can be used and explore the need to note when using generators

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.
