This repository is a Unity-based MMORPG framework that extends the MultiplayerARPG template to support a multi-server architecture with central, map, and database servers. The client provides a full pre-game UI flow (login, registration, server/channel selection, character creation) and in-game features such as guilds, parties, mail, cash shop, gacha, storage, and IAP validation. The server is component-based, with CentralNetworkManager handling authentication and character operations, MapNetworkManager managing per-map gameplay and persistence, and DatabaseNetworkManager abstracting SQLite/MySQL storage. Data flows involve periodic saving of player and building state via data updaters with hash-based change tracking, and caching of social data (parties, guilds) with configurable refresh intervals. External dependencies include LiteNetLib for networking, SQLite/MySQL for databases, and custom ASN.1 parsers for Apple/Google Play receipt validation. The codebase demonstrates modular design through interfaces (IDatabaseClient, IChatProfanityDetector, IIAPReceiptValidator) and reusable utilities (MiniJSON, Asn1Processor).

OptimaJet.Workflow is a .NET workflow engine library designed for business process management and automation. It provides a core runtime for defining, executing, and persisting workflow schemes (process definitions) across multiple database backends including SQL Server, MySQL, PostgreSQL, Oracle, SQLite, and MongoDB. The engine supports multi-tenancy, version control of workflow schemes, and includes a visual HTML5 designer for creating workflows. It is architected as a library/framework layer, intended to be integrated into applications rather than running as a standalone service. The codebase demonstrates a hybrid architecture, combining modern .NET Core samples with legacy .NET Framework implementations using Windows Workflow Foundation (WWF). This duality is evident in the presence of both `OptimaJet.Workflow.Core` (modern) and `Other/WorkflowFoundation` (legacy) directories. The library relies heavily on the Provider Pattern for persistence, allowing developers to swap database backends via dependency injection. It also features a robust migration framework (FluentMigrator for SQL, custom scripts for MongoDB) to manage schema evolution, particularly around multi-tenancy support (`TenantId` columns). While the library offers solid engineering patterns like generic database abstraction (`DbObject<T>`) and async/await persistence, the codebase suffers from significant technical drift. It includes deprecated technologies such as `System.Workflow` and WCF, and sample applications rely on older versions of frameworks like ABP (v6.5.0) and .NET Core 2.2. The duplication of persistence logic across five different database providers increases maintenance overhead and the risk of schema drift between implementations.

DBeam is a mature Java library and CLI tool that extracts data from SQL databases (PostgreSQL, MySQL, MariaDB, H2) and exports it as Apache Avro files, typically stored in Google Cloud Storage. It operates as a single-threaded Apache Beam pipeline, first inferring the table schema by reading one row, then streaming the full result set via JDBC directly into Avro binary encoding using a custom Beam sink. The tool supports partitioned exports, parallel query execution via a split column (experimental), multiple Avro codecs, KMS-decrypted passwords, and various array handling modes. It is designed for reliability in production batch data extraction pipelines and has been in use at Spotify since 2017. The codebase is well-tested and uses modern Java practices (AutoValue, Beam SDK 2.76), with CI/CD workflows for Maven Central releases.

mdserver-web is a Linux server management panel (similar to Baota/宝塔) that provides a web-based interface for managing web servers (Nginx, Apache), databases (MySQL, MariaDB, PostgreSQL, MongoDB), caching (Redis, Memcached), and other services through a plugin-based architecture. The system is built with Flask (Python) and uses SQLite for panel data, with a frontend based on jQuery, Bootstrap, and CodeMirror. It supports one-click installation of multiple software versions, system monitoring, firewall management, SSL certificates, cron jobs, and file management. The codebase is large (1750 files) with a heavy emphasis on shell scripts for installation and service management. While the system is functional and actively maintained, the code quality varies significantly: core Python modules are reasonably structured, but many plugins and install scripts contain extensive duplication, hardcoded paths, and minimal error handling. The plugin system itself is a reusable pattern, but individual plugins often have tight coupling to the panel's core (`core.mw`). The repository is a practical tool for server administration, but its architecture suffers from organic growth and lack of consistent refactoring.

This repository is a full-stack, multi-client rental property management platform called 'rightHouse' (房适). It consists of three frontends: a Vue 3 + Arco Design admin panel (RH-admin), a uni-app landlord mobile app (RH-landlord), and a uni-app tenant mobile app (RH-tenant), all backed by an Egg.js Node.js REST API (RH-server) with MySQL, Redis, MinIO, and OSS storage. The system enables landlords to publish houses, tenants to search and apply for rentals, and administrators to manage users, houses, and lease applications. Key workflows include lease application with approval flow, maintenance requests, rental market listings with location-based search, and tenant reviews. The architecture is monolithic on the server side but with separate client applications sharing some UI components (uView UI) and a custom HTTP client (luch-request). The codebase is functional and covers the full rental lifecycle, but suffers from duplicated UI component libraries across mobile apps, mixed Vue 2/Vue 3 frameworks, hardcoded configuration values, and lack of automated tests. The admin panel uses modern Vue 3 tooling, while the mobile apps rely on the older uView 2.0 library. The server side includes JWT authentication, SMS notifications, and file upload capabilities. Overall, it is a solid but not exceptional implementation of a rental management system, useful as a reference for similar multi-tenant applications but with several areas of technical debt.

Tieba-Cloud-Sign is a PHP web application designed to automate the sign-in process for Baidu Tieba forums. It provides a web interface for managing multiple Tieba accounts (via BDUSS cookies) and scheduling automatic sign-in tasks through a built-in cron system. The application features a plugin architecture that allows extending functionality, such as pushing sign-in results to QQ via go-cqhttp or backing up the database to QQ. The core system handles user authentication, Tieba API interactions (including retrieving TBS tokens and performing sign-ins), and provides an administrative interface for configuration. Plugins are integrated via hooks and can add their own settings, cron jobs, and UI components. Data is stored in a MySQL database, with tables for users, account credentials, plugin configurations, and operational logs. Key technical components include a custom WebSocket client for real-time communication with go-cqhttp (used by QQ-related plugins), a SQL dump utility for database backups, and an AJAX-driven settings interface. The frontend relies on Bootstrap 3.3.2 and jQuery for responsive UI elements, including modal dialogs for plugin configuration.

Pikachu is a deliberately vulnerable web application built as a training ground for web penetration testing, covering common security flaws such as SQL injection, XSS, CSRF, RCE, file inclusion, unsafe file upload/download, SSRF, XXE, and deserialization. It is a LAMP stack (PHP + MySQL + Apache) monolith using a legacy Ace Admin template and Bootstrap 3. The codebase is organized into vulnerability categories under `/vul/`, a main application for navigation and configuration, and a separate XSS management backend (`/pkxss/`) for collecting stolen cookies, phishing credentials, and keystrokes. The project intentionally uses insecure coding patterns (e.g., raw SQL concatenation, `eval()`, `unserialize()` on user input) to demonstrate exploitation, and includes some secure alternatives for comparison. The repository is explicitly marked as 'asleep' by its authors, who recommend a successor project. It is not suitable for production deployment but serves as a valuable educational resource for security students and CTF players.

TravianZ is a self-hosted multiplayer browser strategy game server, a clone of the popular Travian game. It implements the complete game loop: village building, resource production, troop training, combat, hero system (T4), alliance management with bonuses, market trading, world wonders, and an admin panel for server management. The architecture is a PHP 8.3+/MySQL monolith with procedural entry points and class-based game logic. Key systems include a trait-based database layer (Database.php split into domain-specific traits), a cron-like automation engine (Automation.php split into traits), and a templating system using .tpl files. Features include support for 9 tribes, multi-language (English, French, Italian, Romanian, Chinese), Docker deployment, and an admin panel with CSRF protection and logging. The codebase has undergone significant refactoring from an older codebase, but still retains global state, mixed SQL access patterns (prepared statements alongside raw queries), and legacy JavaScript (MooTools). It is actively maintained with documented bug fixes and performance optimizations.

This is a full-stack blog/CMS application built with ThinkJS 3.x (Node.js MVC framework) on the backend and Vue.js 2 + iView UI on the admin panel. The backend serves both a RESTful API and server-rendered public pages (ThinkJS templates). The admin SPA provides CRUD for posts, pages, categories, tags, comments, user management, and site configuration. Authentication uses JWT tokens. Image upload supports local storage or Qiniu CDN. Email notifications can be sent for new comments. The database is MySQL, with models defined using ThinkJS ORM. The codebase follows traditional MVC patterns but relies on heavily outdated dependencies (Vue 2, Webpack 3, iView 2, Node 16), uses an insecure `eval` in the admin, and lacks tests or CI. It is functional for its intended purpose but shows no recent maintenance and would require significant modernization for reuse.

This repository contains a collection of example SQLMap command lines for bypassing Web Application Firewalls (WAF) during SQL injection penetration testing. It is essentially a cheat sheet or reference guide, not a software application. The content is provided in plain text files with various tamper script combinations and techniques. The repository has no actual code, scripts, or executable components; it solely consists of documentation and example usage. While the commands may be useful for security professionals, the repository itself is not a functional tool and has seen no active development since its creation around 2021.

This repository contains a technical book titled 'The Art of Problem-Solving in Software Engineering: How to Make MySQL Better'. It is structured as a collection of Markdown files covering MySQL internals, performance optimization, and problem-solving methodologies. The book does not contain executable code or data processing scripts; instead, it provides theoretical explanations, case studies, and references to MySQL versions 8.0.x and 5.7. Topics include transaction throttling, latch sharding, hybrid data structures, Group Replication enhancements, and performance testing techniques using tools like BenchmarkSQL and SysBench. The repository serves as an educational resource for database administrators, performance engineers, and MySQL contributors seeking to understand and resolve MySQL scalability and performance issues. It emphasizes analytical approaches over trial-and-error, drawing from computer science fundamentals such as queueing theory, distributed systems, and algorithmic optimization. While the book references benchmark results and visualizations (stored as images in the media/ directory), it does not include the raw data, scripts, or tools needed to reproduce those results. As a documentation-focused repository, it lacks traditional software engineering components like APIs, CLI tools, or reusable libraries. Its value lies in the consolidated knowledge presented across chapters, which readers can apply to MySQL tuning and troubleshooting scenarios. The content appears well-organized and researched, but the absence of runnable code or data assets limits its direct utility as a software artifact.
