Article Introduction：To solve the problem that VSCode causes the Explorer to refresh continuously due to frequent changes in files, you can configure the ignorant file monitoring behavior. The specific steps are: 1. Add files.watcherExclude configuration item in the .vscode/settings.json file in the root directory of the project; 2. Use glob pattern matching rules to set files or directories to be excluded, such as "**/*.log":true ignores .log files in all locations, and "**/tmp/**":true ignores tmp folders and contents at any level; 3. If the configuration does not take effect, check whether the path is correct, the impact of plug-in monitoring, and multiple configuration conflicts.

Article Introduction：IntersectionObserver is a practical API provided by H5, suitable for lazy loading and animation triggering. 1. Lazy loading pictures: By monitoring whether the element enters the viewport, assign the real image address from data-src to src to reduce the loading pressure on the first screen; 2. Animation trigger: When the element enters the field of view, add class names to start CSS animation, save resources and improve experience; 3. Usage tips: reuse Observer instances, cancel monitoring in time, pay attention to compatibility and mobile adaptation issues. Compared with scroll events, IntersectionObserver has better performance and concise code.

Article Introduction：The problem of the middle click cannot open a new tab in the browser, which is usually caused by plug-in conflicts, browser settings abnormalities, mouse driver configuration or system shortcut keys. 1. First check whether all extension test functions can be temporarily disabled due to browser extensions (such as ad blocking plug-ins), and troubleshoot problems plug-ins one by one; 2. Troubleshoot the browser's own settings, cache exceptions or experimental function restrictions, try to clear cache, use incognito mode, or check event blocking behavior in the developer tool; 3. Check the mouse driver settings, confirm that the intermediate scroll wheel action has not been remapped, and test the mouse's performance on other devices or browsers; 4. If the problem is still not solved, technical users can simulate the intermediate click behavior through scripts or key mapping tools as an alternative.

Article Introduction：The choice of SQL query optimization tool depends on the usage scenario. 1. Open source tools such as DBeaver and MySQLWorkbench are suitable for small and medium-sized projects. The former supports multi-database and interface-friendly, while the latter is specially designed for MySQL and has built-in visual analysis functions, but the two lack automation suggestions. 2. Commercial tools such as SolarWindsDPA and Datadog are suitable for enterprise environments. The former provides real-time monitoring and automatic indexing suggestions, while the latter supports full-stack monitoring and can locate system-level problems, but are at a high price. 3. Integrated solutions such as JetBrainsDataGrip plug-in and AzureDataStudio are suitable for use in the development stage. They can write and check to improve efficiency, but in-depth analysis

Article Introduction：The key to Java debugging is to master the use of VisualVM and JConsole tools. 1. VisualVM is a graphical troubleshooting tool that integrates multi-JDK tools. It can view the JVM running status in real time, analyze hotspot methods and frequent objects through "Sampler", and supports remote monitoring configuration and plug-in extensions. 2. JConsole is suitable for quickly viewing memory, threads, and class loading, and can detect deadlocks and observe GC frequency. 3. It is better to use the two in combination: first use JConsole to observe the exception, then deeply analyze the performance bottlenecks through VisualVM, and it is recommended to grab heapdump for further diagnosis.

Article Introduction：Use Flask's before_request and after_request hooks to simulate middleware functions, suitable for in-app logic such as logging, performance monitoring and authentication; 2. Lower-level control can be achieved through WSGI middleware, such as modifying environment and response headers, suitable for cross-frame reuse or plug-in design; 3. The JWT authentication example shows how to perform permission verification before requesting and inject user information, and pass data in combination with g objects. Summary: Most scenarios recommend using the Flask hook function, because it is simple and efficient. WSGI middleware is only selected when the underlying WSGI control is needed. The combination of the two can flexibly implement various middleware requirements.

Article Introduction：Using IntersectionObserver API to achieve lazy loading can effectively improve page loading speed and reduce bandwidth consumption; 2. By storing the real image address in the data-src attribute, combined with IntersectionObserver listening elements to load the image when they enter the viewport; 3. The advance loading conditions can be configured through threshold and rootMargin to optimize the user experience; 4. Placeholders and fixed width and height should be set to prevent layout offset; 5. The same method is suitable for lazy loading of embedded content such as iframes; 6. The performance of this solution is better than traditional scroll event monitoring, and modern browsers widely support it. If necessary, loading="la can be downgraded if necessary
