MacBook won't detect external monitor

MacBook won't detect external monitor

MacBooks do not recognize external monitors are usually caused by connection, setup, or compatibility issues, rather than hardware corruption. 1. Check whether the cable is intact and whether the interface is tight, and confirm that the monitor power and input source are correct; 2. Try to restart the system, reset the display settings or use safe mode to troubleshoot software conflicts; 3. Adjust the resolution/refresh rate or update the monitor firmware to improve compatibility; 4. Further troubleshoot through third-party tools, terminal commands or create a new user account; 5. If the above steps are invalid, it is recommended to detect the monitor itself or contact professional repairs.

What is the difference between function declaration and function expression in JavaScript?

What is the difference between function declaration and function expression in JavaScript?

Function declarations are directly defined using the function keyword, and function expressions assign functions to variables; 2. Function declarations are completely improved and can be called in advance, function expressions are only variable promotion and cannot be called in advance; 3. Function declarations are created during parsing, function expressions are created at runtime, and conditional definitions are supported; 4. Function declarations are suitable for scenarios that require advance call and readability, and function expressions are suitable for dynamic assignment, callbacks and conditional logic scenarios. Therefore, function declarations are available earlier and function expressions are executed sequentially.

How to Perform Point-in-Time Recovery Using the Binary Log?

How to Perform Point-in-Time Recovery Using the Binary Log?

To restore the MySQL database to a specific point in time, you must first restore the complete backup, and then use binary logs to replay the changes. The specific steps are: 1. Use mysqldump and other tools to restore the most recent complete backup to bring the database back to the state at the time of backup; 2. Use mysqlbinlog to analyze the binary logs in combination with time range or location information, and locate the time point or event location that needs to be restored; 3. Use mysqlbinlog to read the binary log from the backup time to the target time point, and redirect its output to the MySQL server for execution, thereby replaying all legal operations within this time period; To ensure accuracy, it is recommended to use log location instead of timestamp, and test the recovery process in a non-production environment, and enable-

How does garbage collection work in Golang?

How does garbage collection work in Golang?

Go's garbage collection (GC) is automatic, using a concurrent three-color mark removal algorithm, implements concurrent collection through a write barrier, optimizes short-life cycle object recycling, and maintains low pause time. Developers can improve performance through object reuse and avoids memory leaks. 1.GC marks accessible objects from the root object and clears unreachable objects. 2. Write barrier ensures that reference updates are not omitted during concurrency. 3. Although there is no explicit generational division, it is optimized according to "most objects die prematurely", and short-cycle GC is frequently executed. 4. Only submillisecond pauses will occur at the beginning and end of the mark to ensure low latency. 5. Developers can use sync.Pool to reuse objects to reduce allocation pressure and avoid memory problems caused by long-term holding of large objects or global references. Go's GC runs efficiently in the background and balances

How to create a sticky header with CSS?

How to create a sticky header with CSS?

To create a sticky header, just use CSS's position:sticky; first apply position:sticky to the head element and set top:0 to fix it when scrolling to the top of the viewport; make sure that the parent container does not have properties that disable sticky behavior, such as overflow:hidden or transform; to improve visual effects, background colors, box-shadow, z-index and transition animations can be added; finally verify that the HTML structure is correct and the content is enough to trigger scrolling. This method is widely supported in modern browsers and can be implemented without JavaScript.

How to provide a fallback image for browsers that don't support a specific format in HTML

How to provide a fallback image for browsers that don't support a specific format in HTML

Use elements to combine multiple tags to achieve compatibility support for modern image formats. 1. The browser tries to load the specified image format in sequence; 2. Prioritize the use of newer formats such as AVIF and WebP; 3. If none of them are supported, fall back to widely supported formats such as JPEG or PNG; 4. The tag must be retained at the end as the final fallback to ensure that all browsers can display images; 5. This method does not require JavaScript, which is more reliable and efficient than onerror; 6. Responsive image loading can be achieved by combining srcset and media; this solution ensures that modern browsers enjoy efficient compression formats while ensuring that old browser users view pictures normally. It is a semantic, standardized and accessible best practice.
