Disabling hardware acceleration is the most common way to solve the problem of black screen of Google Chrome on Windows 10. It can be achieved by setting or adding --disable-gpu parameters in the shortcut; 2. Update or use the DDU tool to completely reinstall the graphics card driver to troubleshoot driver compatibility issues; 3. Reset the experimental features in Chrome://flags to the default state to avoid rendering failures due to abnormal settings; 4. Clear Chrome's GPU cache folder (ShaderCache) to fix the black screen caused by cache corruption; 5. If the problem remains the same, uninstall and reinstall Chrome to troubleshoot program files; In addition, you can try to enable "overwrite" in Chrome://flags

Use the signal.Notify() function in the os/signal package to listen to system signals such as SIGINT and SIGTERM. 2. It is recommended to use a channel with a buffer size of 1 to avoid signal loss. 3. In scenarios such as HTTP servers, elegant shutdown with timeout can be triggered by receiving signals. 4. Signal monitoring can be stopped by signal.Stop(). 5. SIGKILL and SIGSTOP should be avoided. The program should clean up resources correctly and exit.

Create a modular application of Java9, you must first write the module-info.java file to define the module name, dependency and export package; 2. Organize the code according to the standard directory structure, such as src/module name/; 3. Use javac to compile to the output directory with --module-source-path and -d; 4. Run the main class of the specified module through java-module-path and -m; 5. If there is a dependency, you must declare requirements in module-info and compile together; 6. You can optionally use the jar command to package it as a modular JAR and run it with --module-path; modularity improves maintainability through clear encapsulation and dependencies, and must be exported to access

object-fit is a way to control media elements to fill containers. The width and height of the element must be set to take effect. 1.fill will stretch the image and may cause deformation; 2.contain scale to ensure that the full image is displayed but may leave blank; 3.cover scale to scale but may be cropped; 4.none maintains the original size; 5.scale-down selects a smaller scaling method; it is often used in picture and video containers, and adjusts the focus with object-position. It is recommended to use cover or contain in responsive design and test different screen sizes to achieve a consistent layout without distorting content. This property is well supported in modern browsers and can be used safely.

std::back_inserter is used to automatically insert elements into containers that support push_back in STL algorithms. 1. Must include header files; 2. It is often used with algorithms such as std::copy, std::transform, etc. to avoid undefined behavior caused by insufficient space in the target container; 3. It is suitable for dynamic containers such as std::vector, std::list, std::deque, etc., and cannot be used for containers that do not support push_back such as std::set or std::array; 4. The insertion operation is always appended to the end of the container, and will not overwrite existing elements, making the code safer and more concise.

First generate the SSH key pair, then copy the public key to the server, and finally optionally disable password authentication; the specific steps are: 1. Run ssh-keygen-trsa-b4096-C "your_email@example.com" on the client to generate the key pair, save the private key in ~/.ssh/id_rsa, and save the public key in ~/.ssh/id_rsa.pub; 2. Use ssh-copy-idusername@server_ip to copy the public key to the CentOS server, or manually append the public key to ~/.ssh/authorized_keys, and set the permissions chmod700~/.

There are three ways to check whether the key in std::map exists: 1. Use find(), the recommended method, time complexity O(logn), and do not modify the map, which is efficient and safe; 2. Use count(), the code is concise but the performance is slightly lower than find(), which is suitable for scenarios that are insensitive to performance; 3. Use contains(), introduced by C 20, with clear semantics and good performance, which is the first choice for modern C; pay attention to avoid using operator[] to judge existence, because it will insert default values when the key does not exist, resulting in unexpected behavior; Summary: Use contains() for C 20 and above, and use find() first for old versions, and use count() for simple scenarios.

Safari needs to manually enable permissions to access the camera and microphone. The specific steps are as follows: 1. Enter "Privacy and Security" in the macOS system settings to ensure that Safari is checked to allow the use of the camera and microphone; 2. In the "Website" tab of Safari's preferences, find the camera and microphone options respectively, and set the target website to "Allow"; 3. When the web page requests permission, click the address bar to select "Allow". If it is wrong, you can adjust it manually through settings. The above operations must be set in the system and browser at the same time, otherwise it will not be used normally.

SUMPRODUCT can not only multiply and sum the array elements in Excel, but also achieve flexible condition summing and counting through logical conditions. 1. The basic usage is =SUMPRODUCT(array1,[array2],...). All arrays need the same dimensions, and non-numeric values are regarded as 0. When a single array is directly summed. 2. Simple multiplication and addition calculations such as =SUMPRODUCT(A2:A5, B2:B5) can obtain the total sales of 194. 3. Logical expressions available for condition summing, such as =SUMPRODUCT((A2:A10="North")C2:C10) realizes only summing of sales of "North" areas. 4. Use multiple logic when multiple conditions

Create a custom DefaultHandler and rewrite startElement, endElement, characters and other methods to handle parse events; 2. Create a SAXParser instance using SAXParserFactory, and associate the XML file with the custom processor through the parse method for parse; 3. SAX parsing is based on event-driven, with low memory usage, and is suitable for large files, but can only be read in sequence and cannot modify XML. The context state needs to be manually maintained to handle nested structures. The parsing process starts from startDocument to endDocument.

You can use requests.get() to initiate a GET request and check status_code and response content; 2. Support POST, PUT, DELETE and other methods, such as requests.post(url,json=data) to send JSON data; 3. You can add request headers and query parameters through headers and params parameters; 4. You should use the try-except block to catch exceptions and call raise_for_status() to handle errors; 5. You can set t
