How to optimize image assets in a Vue app?
Article Introduction：Optimizing image resources in Vue applications requires starting from three aspects: format selection, lazy loading and distribution strategies. 1. Use WebP format to replace PNG/JPG, and automatically generate and fall back through the construction tool; 2. Enable lazy loading, combine IntersectionObserver or component library, configure placeholder maps and exclude the content on the first screen; 3. Introduce CDN distribution as needed, call tool function stitching paths uniformly, and access object storage acceleration services; 4. Compress pictures before uploading, and further reduce the size in combination with automation tools or CI/CD processes.

How to convert a string to an int in C ?
Article Introduction：The recommended way to convert a string to an integer in C is to use the std::stoi function. 1.std::stoi is the simplest and most direct way in modern C (C 11 and above). It is defined in a header file and can automatically handle most cases, but will throw exceptions. It needs to be used in combination with try-catch; 2.atoi is a C standard library function, which accepts constchar* type, which is simple to use but poor error handling ability, and returns 0 when encountering illegal characters; 3.std::istringstream provides a more flexible parsing method, suitable for complex parsing scenarios, but has a slightly lower performance. Choose the appropriate method according to your needs, and recommend std::stoi first.

MySQL dual master hot standby solution based on Keepalived
Article Introduction：The MySQL dual master hot standby solution based on Keepalived ensures that the database service is not interrupted. 1. Keepalived monitors the database instance, and switches the VIP to the backup library when the main library fails; 2. MySQL replication function (such as GTID) ensures the synchronization and consistency of the data of the two main libraries; 3. Keepalived relies on the heartbeat package to detect the status of the main node through the VRRP protocol, and switches the VIP according to the configuration parameters (priority, detection interval, etc.). Carefully configures to avoid the phenomenon of split brain; 4. A script is required to monitor the MySQL status and troubleshoot problems in combination with logs; 5. High availability requires selecting appropriate hardware, regular backups, reasonable monitoring, and continuous maintenance and optimization.

How to properly initialize a golang struct with default values?
Article Introduction：In Go language, the default initialization of the structure can be achieved through constructors, nested structures, or reflections. 1. It is recommended to use a constructor starting with New to return a structure pointer with a default value to improve readability and scalability; 2. If multiple structures share fields, they can be extracted into an infrastructure structure and encapsulated default initialization logic to reduce duplicate code; 3. For complex scenarios, if a large number of field default values ??need to be dynamically processed, a general initialization function can be written in combination with field labels and reflections, but pay attention to performance and readability. The standard library does not directly support this function, and some third-party libraries are optional. The core is to keep the initialization logic unified and clear.
