FastestMirror Project Summary

Project Overview

FastestMirror is a professional Go application that automatically detects Linux distributions and finds the fastest package repository mirrors. It's designed to be both technically impressive and subtly entertaining - perfect for a resume project.

Key Technical Features

🏗️ Architecture

• Clean Architecture: Organized with cmd/, internal/, and pkg/ structure following Go best practices
• Modular Design: Separate packages for distribution detection, mirror testing, and configuration management
• Concurrent Processing: Uses Go goroutines for parallel mirror testing
• Error Handling: Robust error handling throughout with meaningful error messages

🔍 Distribution Detection

• Parses /etc/os-release, /etc/lsb-release, and fallback detection methods
• Supports major Linux families: Debian, Arch, Fedora, openSUSE, Gentoo, Alpine, etc.
• Graceful fallback mechanisms for edge cases

⚡ Mirror Testing Infrastructure

• Concurrent HTTP speed testing with configurable timeouts
• Latency measurement and download speed calculation
• Smart scoring algorithm combining multiple metrics
• Proper connection handling and resource cleanup

🎨 User Experience

• Beautiful CLI interface with colors and progress bars
• Professional help text with subtle humor
• Comprehensive command structure with subcommands
• Safe operations with backup and dry-run modes

🔧 Configuration Management

• Safe backup creation with timestamps
• Support for major package manager configurations
• Atomic operations with rollback capability
• Proper permission handling and root privilege checks
