When encountering the "Youdonothavepermissiontosaveinthislocation" problem, it is usually caused by insufficient permissions or the folder is locked. Solutions include: 1. Run the program as an administrator and bypass permission restrictions; 2. Modify the permission settings of the target folder, check the permissions of "write" and "modify" to obtain ownership if necessary; 3. Save files in another place, such as desktop or new working folder; 4. Check whether they are occupied by other programs or have read-only attributes set, and make corresponding adjustments.

JavaScript provides a variety of methods to create objects, and should be selected according to requirements: 1. The object literal is suitable for simple singleton objects; 2. The constructor is suitable for creating multiple instances with the same structure; 3. The ES6 class provides clearer syntax and supports inheritance; 4. Object.create() can accurately set the prototype; 5. Factory functions can be flexibly created by returning objects; In addition, Object.assign() can be used to merge or clone objects, and the final selection should be based on the specific usage scenario and coding style.

Chrome's utility processes are responsible for handling system-level tasks that are not related to web pages or extensions, such as managing downloads, handling clipboard access, running network stacks, etc. 1. It isolates different types of practical tasks to improve security and performance, such as handling network, GPU and audio related tasks separately. 2. It is normal for multiple utility processes to run at the same time. Each process works independently to prevent one problem from causing overall crash. 3. If a utility process occupies too much resources, it may be caused by temporary operations, such as downloading large files. If it continues to be high, you can try restarting the browser, checking for extensions, or updating Chrome.

std::source_location is a class introduced by C 20 to obtain source code location information. 1. You can obtain file name, line number, function name and other information at compile time through std::source_location::current(); 2. It is often used for logging, debugging and error reporting; 3. It can automatically capture the call location in combination with macros; 4. Function_name() may return a mangled name, and it needs to be parsed with abi::__cxa_demangle to improve readability; 5. All information is determined at compile time, and the runtime overhead is extremely small, suitable for integration into logs or test frameworks to improve debugging efficiency.

To turn off Safari's strong password suggestions, Mac users need to go to "System Settings" → "Password" → uncheck "Auto-fill web passwords"; iPhone or iPad users turn off "Suggestions for using strong passwords" in "Settings" → "Safari Browser". If using iCloud Keychain, you can further turn off its synchronization or delete the saved password. In addition, when using a third-party password manager, the automatic filling order can be adjusted in "Settings" → "Password", rank third-party tools first, and Mac users modify the default behavior in "Keychain Access". Some operations may require restarting the device to take effect.

Return errors are an idiomatic way for Go language to process expected failures. They have the advantages of predictable, controllable, easy to test and high performance. They are suitable for routine errors such as file failure and network timeouts. 2. Panic is used in real exceptions, such as program logic errors or unrecoverable states. They are suitable for catching error assumptions or initialization failures in the development stage, but will interrupt the control flow, have high performance overhead and are difficult to manage; 3. Error return should be given priority to deal with problems in normal operations. Panic should be used only when programming errors, known invalid inputs, or library function pre-checking failures, and should not be used in conventional control processes.

The key to synchronizing Chrome bookmarks on iPhone is account login and synchronization settings. First, make sure that Chrome on the computer has logged in with Google account and enabled bookmark synchronization; secondly, install Chrome on the iPhone and logged in with the same account, and the system will automatically synchronize the bookmarks; if it is not displayed immediately, you can check whether the account is consistent or wait for the synchronization to be completed; in addition, you can add multiple accounts through settings but only one can be synchronized, or add common websites to the home screen bookmark bar; if you don’t want to use Chrome, you can also import bookmarks into Safari through third-party tools, but the operation is more complicated.
