SQL Database Migration Tools and Strategies
Article Introduction：SQL database migration requires choosing the right tools, making preparations, and adopting reasonable strategies. Recommended tools include AWSDMS for cloud migration, SSMA for SQLServer ecological migration, MySQLWorkbench for migration to MySQL, Flyway and Liquibase for version control. Before migration, you must evaluate the structure and data volume, check compatibility, backup the source library, and verify in the test environment. The migration strategy can choose full incremental synchronization, phased migration, downtime migration or double write mechanisms. Common problems include data inconsistency, performance bottlenecks, structural conversion failures and permission issues, which need to be dealt with in advance.

How to solve the problem of virtual columns in Laravel model? Use stancl/virtualcolumn!
Article Introduction：During Laravel development, it is often necessary to add virtual columns to the model to handle complex data logic. However, adding virtual columns directly into the model can lead to complexity of database migration and maintenance. After I encountered this problem in my project, I successfully solved this problem by using the stancl/virtualcolumn library. This library not only simplifies the management of virtual columns, but also improves the maintainability and efficiency of the code.

Migrating a Large JavaScript Codebase to TypeScript
Article Introduction：First, configure tsconfig.json that supports progressive migration, and enable key options such as allowJs, checkJs and strict; 2. Adopt a file-by-file migration strategy, prioritize converting tool files or combining JSDoc to obtain type checking benefits in advance; 3. Respond to common problems such as implicitany, third-party library missing types, dynamic attribute access and circular dependencies; 4. Integrate type checking into lint, editor and CI processes to ensure quality; 5. Track progress through statistics of .ts file ratio and error reduction, maintain team motivation, and ultimately achieve a safer and maintainable code base.

Migrating from Python to Go: A Case Study
Article Introduction：The team's delay soared due to the CPU bottleneck and GIL restrictions under high concurrency. After switching to Go, the CPU was reduced by 60-70%, and the average delay was reduced from 120ms to 25ms; 2. Migration challenges include abandoning Python's dynamic features, adapting to Go modules and explicit error handling; 3. Unexpected gains are that static compilation single file deployment, toolchain standardization and ecological library are more reliable; 4. It is recommended to only rewrite the core hot path instead of full migration, gradually replace and measure the effect, and ultimately achieve a 1/3 cost reduction and stability improvement.

Handling character sets and collations issues in MySQL
Article Introduction：Character set and sorting rules issues are common when cross-platform migration or multi-person development, resulting in garbled code or inconsistent query. There are three core solutions: First, check and unify the character set of database, table, and fields to utf8mb4, view through SHOWCREATEDATABASE/TABLE, and modify it with ALTER statement; second, specify the utf8mb4 character set when the client connects, and set it in connection parameters or execute SETNAMES; third, select the sorting rules reasonably, and recommend using utf8mb4_unicode_ci to ensure the accuracy of comparison and sorting, and specify or modify it through ALTER when building the library and table.

How can you clone an Oracle database using RMAN or other methods?
Article Introduction：Methods to cloning Oracle databases include using RMANDuplicate, manual recovery of cold backups, file system snapshots or storage-level replication, and DataPump logical cloning. 1. RMANDuplicate supports replication from active databases or backups, and requires configuration of auxiliary instances and execution of DUPLICATE commands; 2. The cold backup method requires closing the source library and copying files, which is suitable for controllable environments but requires downtime; 3. Storage snapshots are suitable for enterprise-level storage systems, which are fast but depend on infrastructure; 4. DataPump is used for logical hierarchical replication, which is suitable for migration of specific modes or tables. Each method has its applicable scenarios and limitations.

How to Migrate a Large JavaScript Codebase to TypeScript
Article Introduction：Configure tsconfig.json and enable allowJs and checkJs to support progressive migration; 2. Add type prompts in JavaScript files through JSDoc; 3. Rename .js files to .ts one by one by one with bottom-up or high-impact area priority strategies and fix type errors; 4. Enable checkJs and @ts-check to gradually discover type problems in existing JS files; 5. Install the @types package or create .d.ts files to handle third-party library types; 6. Integrate Babel, ESLint and CI/CD to ensure that the build process is compatible and gradually strengthen type checking; 7. Promote team collaboration through training, specifications and code review; the ultimate goal is to continuously improve

Explain Laravel Passport vs Sanctum.
Article Introduction：Sanctum is lighter and suitable for SPA or mobile, while Passport is more powerful and suitable for OAuth2 services. 1. Passport supports third-party authorization for open API scenarios such as GitHub login, and Sanctum is suitable for front-end separation or mobile-side self-use APIs. 2. Passport is complex to install and configure client ID/Secret and token policies. Sanctum is simple to configure and publish migration and modify guard drivers. 3. Passport uses JWT to encrypt tokens without checking the library and verifying it. Sanctum plaintext storage tokens requires each query, but the management is more intuitive. 4. Passport is naturally stateless and suitable for cross-domain deployment, Sanc

Understanding Frontend Build Tools: Webpack vs Rollup vs Vite
Article Introduction：Webpack is suitable for large applications, with comprehensive functions but complex configuration; Rollup focuses on packaging libraries, with small output size and strong Tree-shaking; Vite is based on native ES modules, with fast development speed and suitable for modern frameworks. 1. Webpack is centered on "Everything is a module" and supports code segmentation and rich plug-ins. It is suitable for complex projects but slow to build; 2. Rollup supports ESM by default, outputs clean code, suitable for NPM library release, but weakly handles non-JS resources; 3. Vite uses browser native ESM, does not package in the development stage, starts quickly and supports mainstream frameworks, suitable for new projects, but TS and migration support needs to be improved.
