Use routing prefix for version control, and use Route::prefix('v1') in routes/api.php to group routes through Route::prefix('v1'); 2. Organize the controller by version into directories such as app/Http/Controllers/Api/V1, etc. to keep the code clear; 3. Optionally use AcceptHeader version control to parse the version information in the request header through middleware; 4. Use LaravelAPIResource to customize response structures for different versions, such as V1/UserResource and V2/UserResource; 5. When the old version is deprecated, the user should be notified in advance and the Deprecated response header should be added through middleware.

First, check and turn off the overclocking settings. 1. Enter BIOS/UEFI to restore the default settings or use IntelXTU, AMDRyzenMaster and other tools to cancel the overclocking; 2. Update or roll back the firmware and drivers, including upgrading the BIOS, installing the latest chipset drivers and Windows updates, and uninstalling the latest updates if necessary; 3. Test the hardware stability, run Prime95 or AIDA64 for CPU stress test, use HWMonitor to monitor the temperature, check whether the power supply is stable, and re-plug and unplug the CPU, memory, power cord and other hardware to try to minimize system startup; 4. You can try to disable the core stop or power management functions, such as switching the high-performance power plan through the command line, or

When using uintptr and unsafe packages, it is necessary to ensure that the object pointed to by the pointer is not garbage collected or moved, and is only used for underlying operations if necessary; ?Safe practices include type conversion using unsafe.Pointer, pointer arithmetic with uintptr in a single expression, and immediate return to unsafe.Pointer after pointer arithmetic with uintptr, and priority use of unsafe.Slice and unsafe.String of Go1.20; ?Hidden practices include converting local variable addresses to uintptr and returning, calling uintptr across functions, and creating slices with reflect.SliceHeader; ultimately, prioritize whether there is no unsa or not.

Use make to initialize slices, maps, and channels to make them available non-nil values; 2. Use new to allocate zero-value memory for any type and return a pointer to it, but it is usually only used when a zero-value pointer is needed; 3. Make returns the type itself, while new returns a pointer to the type; 4. In actual development, make should be used to process slices, maps, and channels, while new is less used. It is recommended to use structure literals instead of new initialization structures.

Use CSS to customize the ordered list counter to first define the count through counter-reset and counter-increment; 1. Use ::before and content to combine counter() to display the count; 2. You can set the styles such as lower-alpha or decimal-leading-zero through the second parameter; 3. You can add prefixes such as "Step" or build nested counts such as 1.1; 4. You need to set a list-style:none to avoid default numeric duplication; finally implement a fully customized counting style, suitable for document or design systems.

The id must be unique. One id in each page can only be used for one element, and the class can be reused on multiple elements, and one element can have multiple classes; 2. Scenarios using id include: positioning a single specific element, link anchors within the page, JavaScript operates elements through id, and labels associated with form elements; scenarios using class include: applying the same style or behavior to multiple elements, building reusable UI components, and selecting multiple elements in JavaScript; 3.
