Implementing MySQL Read Replicas for Scalability
Article Introduction：MySQL read replica is a read-only instance created through the master-slave replication mechanism, which is used to share the pressure of master library query. The settings steps include: configuring the main library to enable binlog and create a copy account; configuring the slave library to set server-id and start the copy process; verifying the status and monitoring delays and errors regularly. The application layer can utilize read replicas through manual shunt, connection pooling, middleware proxy, or DNS polling. When using it, you need to pay attention to data consistency, connection limit, index optimization and lack of monitoring.

Speeding up Existing Apps with a Redis Cache
Article Introduction：Redis accelerates existing applications: cache queries to reduce server load
Core points:
Redis effectively accelerates existing applications by caching query results, thereby reducing server stress. It stores query results for a specified time (for example, 24 hours), and then reuses these results, significantly improving application speed.
The installation of Redis can be done through the operating system package manager or manually. The installation process includes avoiding common warnings and ensuring that Redis starts automatically after the server restarts.
The Predis library works with Redis to provide a memory cache layer for applications. This process involves checking whether the results of the current query exist in the cache, if not, get the result and transfer it

Contributing to Open Source: Gatekeeper Case Study
Article Introduction：Contributing to open source projects: A practical case
This article will use a practical case to explain in detail how to contribute code to open source projects. We will take the GateKeeper library as an example to add a counting function and gradually demonstrate the entire process, including communication with the project owner, code implementation, testing, and submitting Pull Request.
Introduction to GateKeeper Library
GateKeeper is a PHP library for user registration, authentication, and authorization. It uses its own database to store and query user records. This makes it completely decoupled from the main application, making it easy to scale and modify.
Add counting function
At present, if GateKeeper wants to obtain the total number of users in the database, it needs to obtain all users first

Jumping from PHP to Go: Blasphemy, Bravado or Common Sense?
Article Introduction：Core points
Migrating the underlying Laravel application of Boxzilla applications from PHP to Go ends up with a more efficient program with better performance, easier deployment and higher test coverage, despite initial concerns about potential business risks.
Go is a compiled language with a standard library that is better than PHP, and can generate faster, smaller applications with fewer lines of code even if external dependencies are considered. The conversion from PHP to Go needs to adapt to new syntax and features, but the end result is considered worthwhile.
Despite PHP's larger community and rich resources, Go's growing popularity, ease of use, and excellent performance features make it a strong contender for developers to consider conversions. The author predicts that the future will be

Introduction to Java Native Interface (JNI) Use Cases
Article Introduction：Common usage scenarios for JNI include improving the execution efficiency of performance-sensitive parts, accessing operating system or hardware-specific features, reusing existing local library resources, and enhancing security and anti-reverse protection. 1. For high-performance tasks such as image processing, encryption and decryption, C/C can be used to implement key logic through JNI to improve efficiency, but attention should be paid to cross-language call overhead; 2. When accessing device drivers, sensor data or system APIs is required, it can be implemented with the help of the JNI call platform related local libraries, and compatibility issues should be considered; 3. In order to reuse existing C/C code assets, it can be encapsulated through JNI for Java application calls to reduce duplicate development, but a reasonable interface should be designed; 4. Placing the key logic at the native layer can increase the reverse difficulty
