Alumnet is a full-stack, AI-powered alumni exhibition and management system designed for school history museums. It consists of three workspaces: a touch-screen kiosk frontend (client) built with Vue 3, Three.js, and Tailwind CSS; an admin dashboard (admin) using Vue 3 and Element Plus; and a backend server (server) built with Express, TypeScript, PostgreSQL (with pgvector), and Qdrant for vector search. The system provides alumni CRUD, AI-powered natural language search via RAG, 3D galaxy visualization, timeline corridor, interactive message boards, video greetings, donation management, and comprehensive admin controls including content audit, backup/restore, and data import. It features JWT authentication with role-based access, privacy data masking, rate limiting, and a layered architecture (routes → services → repositories). The codebase includes extensive testing (unit, integration, property-based with fast-check) and is deployable via Docker Compose or PM2. While primarily an application, it incorporates data engineering patterns through its RAG pipeline and knowledge base management.
This repository is a comprehensive educational reference and cheat sheet for 42 School's C programming curriculum. It contains extensive documentation covering C basics, common mistakes, clean coding practices, development tools, curated learning resources, and tutorials on optimization, graphics, and security. The repository also includes a collection of standalone C/C++ code examples demonstrating various programming techniques (SIMD vectorization, multithreading, bit manipulation, socket programming) and a set of remote coding challenges with automated testing. While not a deployable application, it serves as a valuable learning resource and provides reusable code snippets, particularly the SIMD abstraction header for fast word/line counting.
