To modify the mouse scrolling speed of VSCode, 1. You can add "editor.mouseWheelScrollSensitivity" by editing the settings.json file and set the value (default 1, the larger the value, the faster the faster); 2. Windows users can also adjust the "number of scrolling lines" in the system settings to change the scrolling speed globally; 3. Mac users need to use third-party tools such as Karabiner-Elements or ScrollReverser to adjust the scrolling behavior; in addition, press and hold Ctrl (Mac is Cmd) to scroll to zoom the font, or close "editor.mous

Send plain text emails with smtplib and email.mime; 3. Replace the MIMEText parameter to "html" to send HTML format emails; 4. Use the MIMEBase and encoders module to add file attachments; Gmail users need to enable two-step verification and use 16-bit application password, or you can also choose to yagmail to simplify operations. Finally, always pay attention to security and anti-spam rules, and exit the server connection and end the program after the operation is completed.

Use position:sticky and top:0 to create a sticky head fixed to the top as the page scrolls; 2. For the sticky bottom bar, use position:sticky and bottom:0 to adsorb to the bottom when scrolling to the viewport; 3. If the bottom bar that is always visible, use position:fixed and set bottom:0 and width:100%, while adding margin to the content to avoid occlusion; 4. Ensure that setting z-index prevents hierarchical overlay issues, and note that position:sticky has good compatibility in modern browsers, but it is not supported in older browsers such as IE, and ultimately, it mainly relies on CSS.

First, use the Pattern.compile() method to compile the regular expression into a Pattern object; 2. Then call the matcher() method of the object to create a Matcher instance to match the input string; 3. Use the find() method to find all matches or matches() method to verify the exact match; 4. You can extract the matching content through the group() method or use flags such as CASE_INSENSITIVE to ignore case and other matches; 5. For one-time matching, you can directly use the static Pattern.matches() method to complete. This method is suitable for simple verification, and finally select the appropriate method to complete the pattern matching task according to your needs.

Add a reference to IWshRuntimeLibrary, you can manually add COM references through NuGet installation package or in old projects; 2. Use the CreateShortcut method of the WshShell class to create a shortcut and set attributes such as target path, parameters, description, icon position and working directory; 3. Call the Save method to save the .lnk file to the specified path, ensuring that the path ends in .lnk and has write permissions; finally using IWshRuntimeLibrary is the most concise and reliable method to create .lnk shortcuts in C#, suitable for most scenarios.

When using onMounted and other life cycle hooks in Vue3's Composition API, you must first import from vue. 1. Use import{onMounted}from'vue' to import the hook; 2. Call onMounted(()=>{/processing logic/}) directly to perform post-mount operations; 3. Other hooks such as onUpdated, onUnmounted, etc. also need to be imported and used similarly; 4. All hooks must be executed synchronously in setup and cannot be called in conditions or loops; 5. Actual applications include initiating a request or starting a timer in onMounted, clearing the timer or event monitoring in onUnmounted.

Use the fixed-bottom class to implement a navigation bar fixed at the bottom, but you need to pay attention to content occlusion. The specific steps are as follows: 1. Add the navbarfixed-bottom class to the nav tag to fix the position; 2. To avoid the content being blocked, add margin-bottom (at least 56px) to the main body of the page; 3. You can combine the style to improve contrast or use JS to control the display logic.

Confirm that the signature is displayed correctly and save the file; 4. Verify whether the recipient supports digital signature before sending. In addition, commercial use is recommended to use certificates issued by authoritative agencies to ensure compliance.

Deadlock cannot be completely avoided, but can be effectively managed through the following measures: 1. Catch deadlock errors in application code (such as MySQL's 1213 error) and retry the transaction. It is recommended to use exponential backoff delay; 2. Shorten the time when the transaction holds locks, move non-database operations out of the transaction and commit as soon as possible; 3. Access tables and rows in a consistent order in all transactions to prevent loop waiting; 4. Use a lower isolation level (such as READCOMMITTED) when allowed to reduce the use of gap locks; 5. Optimize indexes to reduce lock contention, ensure that query conditions, connections and sort fields use appropriate indexes; 6. Use SELECT...FORUPDATE and LOCKINSHAREMODE with caution, lock only necessary rows

Using Bootstrap5's Offcanvas component and responsive grid system, it is easy to create a responsive sidebar that slides out on a small screen and is fixedly displayed on a large screen; 2. Trigger the offcanvas display menu through the "ToggleSidebar" button on mobile devices, and the medium and above screen sidebars are always visible as col-md-3 columns; 3. Optionally add desktop folding function through JavaScript, combined with CSS media query to achieve click shrink into narrow bars and hide text; 4. It is recommended to use icons to optimize compact views, keep navigation concise, avoid unnecessary fixed positioning, and test the response effect through developer tools, and ultimately achieve a smooth user experience with minimal code.

Check the status of the application pool, if it is stopped, start and observe whether it is stopped again; 2. Verify the identity and permissions of the application pool to ensure that the account is correct and has sufficient permissions; 3. View the system and application logs in the event viewer to locate the root cause of the error; 4. Check port conflicts and confirm that the website binding port is not occupied by other processes; 5. Try to recycle or rebuild the application pool to eliminate configuration corruption; 6. Enable failed request tracking to analyze the detailed reasons for the 503 error. The root cause of HTTP error 503 in IIS is usually the application pooling problem, and the above steps can be checked one by one to solve this problem.

Iterrows() provides index and row data (Series format), suitable for simple row traversal but slow performance and does not retain data types; 2. itertuples() returns named tuples, faster and retain data types, and is recommended for high-performance requirements; 3. Manual access through indexing and .loc can provide more flexible control; 4. Prioritize vectorization operations using apply() rather than explicit loops; in short, row iteration is only performed when vectorization cannot be used, and itertuples() is recommended for better performance and type support.

Use HttpURLConnection (built-in in Java, no dependencies): Send GET requests through URL and HttpURLConnection classes, set request methods and header information, read response codes and response bodies, suitable for scenarios without external dependencies, but the code is lengthy and error-prone. 2. Use HttpClient (Java11): A modern HTTP client introduced by Java11 supports smooth syntax and asynchronous requests, configures timeouts and read responses concisely. It is recommended for new projects in Java11 and above. 3. Use ApacheHttpClient (external library): powerful function, suitable for complex scenarios, need to add Maven dependencies, and use Clo
