Python's logging module can realize log grading, output to console and files, record exception stacks, etc. 1. Use basicConfig to configure the log format and level, which only takes effect for the first time; 2. Create logger and set the level, output to the console through StreamHandler, and output to the file; 3. Use ifnotlogger.handlers to prevent repeated addition of handlers; 4. Use exc_info=True to record the exception stack when calling the log method; 5. It is recommended to use __name__ as the logger name to identify the source of the module; 6. It is recommended to use dictCon for large projects.

To correctly handle single quotes in SQL, you need to represent single quotes in strings with two single quotes, such as 'O''Connor', which is the standard method for most databases; 1. Use two single quotes in strings to represent a literal single quote; 2. Avoid relying on backslash escapes because their behavior depends on database schema settings; 3. The best practice is to use parameterized queries, and the database driver automatically and safely handle escapes, prevent SQL injection and simplify code.

Data attributes are custom attributes used in HTML to store additional information. They start with data- and can be accessed through the dataset attribute of JavaScript; 1. Use element.dataset to convert the data-* attribute to the camelCase form attribute to read; 2. The read and write values of dataset are strings and need to be manually converted to Boolean or numeric types; 3. Use bracket notation to dynamically access the attribute name. They are suitable for storing element metadata and passing server data to avoid abuse of global variables, but should not store large amounts of data.

Memory alignment is to improve access performance and avoid hardware exceptions, ensuring that data is stored by specific byte boundaries. 1. Members in the structure insert padding bytes according to their alignment requirements. If char is followed by int, 3 bytes must be added to make the int at the 4-byte alignment address; 2. The total size of the structure is aligned to a multiple of the maximum member alignment bytes; 3. Use alignof to obtain the alignment requirements of the type, and alignas specifies a custom alignment method, such as alignas(16) to ensure 16-byte alignment; 4. Use #pragmapack(1) to disable padding to compress the structure size, but may reduce performance or cause unaligned access errors; 5. Memory alignment is particularly important in SIMD, embedded and high-performance scenarios. Correct understanding

To turn off telemetry function of VSCode extensions, you can do it in the following three ways: 1. Disable telemetry globally: Search for telemetry in settings and configure "telemetry.enableTelemetry":false and "telemetry.enableCrashReporter":false; 2. Turn off telemetry for specific extensions separately: Find configuration items similar to python.telemetry.enabled in the extension details page and set to false; 3. Use a firewall or hosts file to block outreach requests: The extension may be

The first answer is: this Makefile is suitable for small to medium C projects, and supports automatic compilation, dependency tracking, and cleaning and reconstruction; 1. Use the G compiler to cooperate with the C 17 standard and debugging options; 2. The source file is located in the src/ directory, and the header file is in the include/ directory; 3. Output the target file to the build/ directory and automatically generate dependencies; 4. Provide all, clean, rebuild and other goals to facilitate the management of the construction process; 5. Automatically discover new source files through wildcard without manually modifying the rules; 6. Contain clear progress prompts and directory creation logic; finally generate the executable file build/app, which fully supports the development process.

Click on "Finish" to open a new private tab with a dark background. At this time, Safari will not save browsing history, automatically fill in data or cookies, but cannot hide IP addresses or prevent tracking of websites and network service providers. Therefore, it is suitable to protect local privacy on shared devices, but it is not the same as the anonymity provided by using a VPN. After use, you need to close all private tabs to completely clear the session.
