# 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

## Commands Implemented

### `fastestmirror find`
- Auto-detects distribution
- Tests mirrors concurrently
- Shows ranked results with performance metrics
- Configurable timeout and result count

### `fastestmirror apply`
- Requires appropriate privileges
- Creates automatic backups
- Applies fastest mirror safely
- Provides post-application instructions

### `fastestmirror version`
