Use Vue's components to wrap elements to achieve transition effects, define CSS class name prefixes through name attributes; 2. Use CSS classes automatically added by Vue at different stages (such as fade-enter-active, fade-leave-to, etc.) to define transition styles, realize fade-out or combine @keyframes to create more complex animations; 3. For list rendering, use components to apply transitions to each list item, and prevent layout jumps by setting position:absolute; 4. Advanced control can be achieved through JavaScript hooks (such as @before-enter, @enter) combined with GSAP and other animation libraries, and set: css=&quo

When Windows File Explorer is unresponsive, you can solve the following methods: 1. Check whether the program occupies too high resources, close the high-occupancy program through the Task Manager or restart the Explorer; 2. If the Explorer is stuck, restart it directly in the Task Manager, or run explorer.exe; 3. Clean up temporary files and use sfc/scannow to repair system files; 4. Update or roll back the graphics card driver to troubleshoot compatibility issues. In most cases, you can restore normal use by operating in sequence.

Use newDate() to get the current date and time object; 2. Use the toLocaleString() method to generate user-friendly localized strings; 3. Use getFullYear(), getMonth(), 1, getDate() and other methods to obtain specific parts such as year, month, day and other methods; 4. Use toISOString() to obtain the UTC time in ISO format; 5. Use Date.now() to obtain Unix timestamps (milliseconds), which are suitable for storage, comparison or logging. The appropriate format should be selected according to specific needs.

The use of NumPy arrays includes: 1. Creating arrays (such as creating from lists, all zeros, all ones, and ranges); 2. Shape operations (reshape, transpose); 3. Vectorization operations (addition, subtraction, multiplication and division, broadcast, mathematical functions); 4. Indexing and slicing (one-dimensional and two-dimensional operations); 5. Statistical calculations (maximum, minimum, mean, standard deviation, summing and axial operations); these operations are efficient and do not require loops, and are suitable for large-scale numerical calculations. Finally, you need to practice more.

Use the memory-profiler library to effectively monitor the memory usage of Python programs. 1. Use the @profile decorator to realize line-by-line memory analysis. You need to install memory-profiler and run the script with python-mmmemory_profiler; 2. Use mprofrun to record the memory consumption when the program is run, and then use mprofplot to generate memory change charts; 3. It is recommended to use @profile only on necessary functions to avoid retaining the decorator in production code. Combined with time.sleep, you can observe memory changes more clearly. You can load and make it in Jupyter through %load_extmemory_profiler and load it with %load_extmemory_profiler in Jupyter.

In C, command line parameters are passed through argc and argv of the main function, where argc represents the number of parameters and argv is the parameter array; 1. argv[0] is the program name, followed by input parameters; 2. It can read all parameters through argv; 3. The boundaries need to be checked during parsing, such as after obtaining -f, the parameters must be ensured to exist; 4. The string can be processed in combination with std::string; 5. Note that different platforms support wmain such as Windows. Mastering this mechanism is the basis for developing command line tools, and parameter boundaries and type conversions must be handled correctly to ensure the safe operation of the program.

Custom elements are part of the WebComponents standard, allowing developers to create reusable custom HTML tags. 1. Create a class that inherits HTMLElement, and use connectedCallback, attributeChangedCallback and other life cycle methods to process logic; 2. Register an element through customElements.define('my-element',MyClass), note that the element name must contain hyphen; 3. Use this element directly in HTML, such as. ShadowDOM should be used to implement styles and structure encapsulation to avoid side effects in the constructor, and

The most secure password management tools depend on specific needs, but Bitwarden, 1Password and Keeper are the first choice; 1. Bitwarden adopts open source mode and AES-256 encryption, and supports two-factor authentication and self-hosting options, suitable for users who value transparency; 2. Top password managers generally use zero-knowledge architecture to ensure that only users can access data and cannot view it by service providers; 3. In terms of user experience, functions such as automatic filling, cross-device synchronization and emergency access improve the convenience of use. For example, 1Password has built-in password generator and anti-phishing detection, and Keeper provides dark web monitoring; 4. In terms of price, Bitwarden provides a free version, with the premium version starting from $10 per year.

To view the size of the database and its tables, you need to use the corresponding methods according to different database management systems: 1. In MySQL, query information_schema.TABLES, use data_length and index_length fields to calculate the size; 2. In PostgreSQL, use functions such as pg_database_size() and pg_total_relation_size() to format the output together with pg_size_pretty(); 3. In SQLServer, you can execute sp_spaceused stored procedures or query sys.master_files and sys.all

Define the relationship in the model class, use hasOne(), hasMany() and other methods to establish one-to-one, one-to-many and many-to-many associations; 2. Access the associated data through attribute syntax to achieve lazy loading, but pay attention to the N 1 query problem; 3. Use with() to actively load to improve performance and support nested relationships; 4. Query the associated data through joinWith() and where(), and conditions can also be added in with(); 5. Saving the associated data requires manual processing, and it is recommended to use transactions to ensure data consistency; 6. Many-to-many relationships are defined through viaTable(), and manually operate the connection table or encapsulation method to manage the association; correctly use indexes, avoid the abuse of lazy loading, and use active loading and transactions reasonably

Running a database container must ensure persistence, security and correct configuration. 1. Select the official image and use the version tag; 2. Use DockerCompose to manage services, configure environment variables, port mapping and named volumes; 3. Always use named volumes such as db-data:/var/lib/postgresql/data to ensure data durability; 4. Set strong passwords, avoid exposing ports, use Docker network to isolate services and use .env files to manage sensitive information; 5. Connect the database from the application or client through localhost and specified ports; 6. Export backup commands regularly such as dockerexec-t container pg_dump and automate with scripts; 7.

Open settings and enter the Face ID and password (or Touch ID and password); 2. Click to open the password and select the password type, including custom code, 4-digit or 6-digit password; 3. Enter and confirm the selected password, optionally use a custom alphanumeric password to enhance security; 4. It is recommended to avoid using easy-to-guess passwords such as birthday or "1234", and enable the clear data function after 10 failures to improve security; 5. After setting, you need to enter a password every time you unlock your phone, authorize purchases, or use ApplePay, even if the Face ID or Touch ID is enabled. Your iPhone is now better protected by setting a password.

When G-Sync is turned on, Chrome plays videos or scrolls the page flashes, mainly due to conflicts between graphics card, monitor settings and browser rendering. The solution is as follows: 1. Confirm the display refresh rate matches and enable G-Sync correctly; 2. Turn off "Allow G-Sync in window mode" to reduce switching interference; 3. Disable hardware acceleration in Chrome and restart the browser; 4. Specify high-performance GPU for Chrome through the NVIDIA control panel; 5. Modify Chrome startup parameters and add --disable-gpu--disable-software-rasterizer to force software rendering; 6. Update the graphics card driver and Chrome to the latest version to repair
