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.

To create the Bootstrap5 drop-down menu, you need to first introduce the Bootstrap's CSS and JS files, and then build the structure using specific classes and data attributes. 1. Introduce BootstrapCSS and JS through CDN in HTML; 2. Create drop-down buttons, use the .dropdown-toggle button, and data-bs-toggle="dropdown" attribute, and add .dropdown-menu and .dropdown-item to build menu items; 3. Understand the structure: .dropdown is an outer container, button is used to trigger, .dropdown-

Install the BIND package; 2. Configure the named.conf file to allow query and recursion; 3. Create forward zone files and define A records; 4. (Optional) Create reverse zone files to support PTR records; 5. Set correct file permissions and SELinux context; 6. Enable and start named services; 7. Configure the firewall to allow DNS traffic; 8. Use named-checkzone, named-checkconf and dig to test the configuration; 9. Point the client DNS to this server; each time you modify the zone file, you need to increment the serial number. It is recommended to configure the DNS server from the DNS server and disable public recursion to ensure security. After all steps are completed, the DNS server will run normally.

To clear all items in the session storage, you should use the sessionStorage.clear() method, which is the easiest and most effective way. You can remove all key-value pairs in the current domain. It is suitable for scenarios such as user logout, reset application status, or prevent data retention between sessions. Note that this operation is irrevocable and only affects the current source (protocol, host, and port). The data will continue to exist before the end of the page session. If you only need to delete a specific item, you can use sessionStorage.removeItem('keyName') to remove one by one, but if the goal is to clear all data, you should use sessionStorage.clear() to complete it.

Use semantic HTML, provide text substitution, ensure the keyboard is accessible, use ARIA reasonably, organize titles correctly, label form elements, ensure color contrast, use descriptive links, and test with real users through tools; 1. Use semantic HTML elements such as, , etc.; 2. Add alt attribute or alt="" to the picture; 3. Ensure that all interactive elements can be accessed through the keyboard and retain the focus style; 4. Use aria-label or aria-describedby if necessary; 5. Use h1 to h6 titles at logical levels; 6. Each form control should have corresponding label tags; 7. Text and background contrast should reach at least 4.5:1; 8. Avoid "points"

Use dict() to directly convert the list containing key-value pairs into a dictionary; 2. When the keys and values are stored in two lists, use dict(zip(keys, values)) for mapping; 3. If you need to use an index as a key, you can implement it through {index:valueforindex,valueinenumerate(items)}; 4. For custom key-value logic, you can use dictionary derivation formulas, such as {item:default_valueforiteminlist} or generate values based on functions; choose a suitable method based on the data structure, the key is to clarify the source of the keys and values, and then perform the correct mapping.

The path parameters are used to extract dynamic values from the URL. FastAPI realizes automatic parsing and verification through type prompts; 1. In the basic usage, {user_id} is used as a parameter, and the input can be automatically converted and verified with the int type prompts. For example, /users/42 returns user information, and non-numbers will be reported as 422 errors; 2. Support multiple path parameters, such as /users/{user_id}/items/{item_id}, which can extract the integer user_id and string item_id at the same time; 3. Enum type restriction values can be defined in combination with Enum, such as Category enumeration only allows electronics, books, and clothes, otherwise 422 errors will be returned; 4.

ORDERBYRAND() should be avoided for large tables, 1. Small table (=(SELECTFLOOR(RAND()(MAX(id)-MIN(id) 1)) MIN(id)FROMyour_table)ORDERBYidLIMIT1; 3. The better solution is to generate a random ID and find the first record greater than or equal to the ID, and cooperate with the retry mechanism to deal with the ID gap; 4. Pre-computed random columns with indexes can be added in high-performance scenarios, such as ALTERTABLEyour_tableADDCOLUMNrand_colFLOAT, CREATEINDEXidx_randONyour_table(rand)

Go does not have built-in functions to find the maximum or minimum values in slices, but it can be implemented through loops; 1. Iterate through the slices and record the current minimum and maximum values; 2. The empty slices should return a boolean value to indicate whether it is successful rather than panic; 3. It can be implemented separately for int, float64 and other types; 4. Go1.18 can use generics to write general functions with constraints.Ordered, but it should be noted that the constraints package is not a standard library, and the production environment should be used with caution; the most effective and clear method is a single traversal.

The key to drawing subgraphs using matplotlib is to create multiple subgraphs through plt.subplots() and personalize them. 1. plt.subplots() returns fig (graphic object) and axs (subgraph array), 2. Use axs[i,j] to index subgraphs (when multi-dimensional array), 3. Use plt.tight_layout() to automatically adjust the spacing to prevent overlap, 4. Use subplot_mosaic to achieve non-uniform layout (such as a subgraph occupying multiple grids), 5. Use shareex/sharey parameters to share axes, 6. Use fig.delaxes() to delete unused subgraphs, 7. Use fig.suptitle() to set it with fig.suptitle().

When using Yii2 or Yii3 to format data display, clear separation should be achieved through Formatter components, model getter methods, GridView/DetailView configuration and custom auxiliary tools; 1. Use Yii::$app->formatter to standardize date, currency, Boolean values, etc. and can be set uniformly in the configuration; 2. Define getter methods in the model such as getFormattedPrice to encapsulate reusable formatting logic; 3. Use format options and anonymous functions in the GridView or DetailView to achieve view-level formatting; 4. Use static help classes or custom small

Create an element using document.createElement(); 2. Optionally add content or attributes; 3. Add elements to the DOM using appendChild() or append(). For example: constp=document.createElement('p');p.textContent='Thisisaparagraph.';document.body.append(p); element must be mounted to the DOM to be visible, and create→configure→append is the standard process.
