# FDJ SLAYER
|
|
|
|
A Python application that generates random EuroMillions lottery draws using multiple entropy sources to maximize randomness.
|
|
|
|
## Description
|
|
|
|
This project aims to create truly random EuroMillions lottery draws by combining various entropy sources including hardware information, weather data, system metrics, and cryptographic functions. It generates a configurable number of draws and allows users to view them.
|
|
|
|
## Features
|
|
|
|
- Multiple entropy sources for good randomness:
|
|
- Weather data from [OpenMeteo API](https://open-meteo.com/)
|
|
- Hardware and system information
|
|
- OS random data and cryptographic functions
|
|
- CPU/memory usage and other dynamic metrics
|
|
- Configurable number of lottery draws
|
|
- Progress bar visualization during draw generation (yes, it's a huge feature :p)
|
|
|
|
## Installation
|
|
|
|
1. Clone the repository:
|
|
```bash
|
|
git clone https://github.com/Floriansylvain/FDJ-SLAYER.git
|
|
cd FDJ-SLAYER
|
|
```
|
|
|
|
2. Install dependencies:
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
## Usage
|
|
|
|
Run the main script to generate lottery draws:
|
|
```bash
|
|
python main.py
|
|
```
|
|
|
|
The program will:
|
|
|
|
1. Generate the configured number of random draws
|
|
2. Display a randomly selected draw as the final result
|
|
3. Allow you to view additional draws on request
|
|
|
|
## How It Works
|
|
|
|
The application uses a combination of entropy sources to generate truly random lottery draws:
|
|
|
|
1. **Static Entropy Sources**:
|
|
- OS random data
|
|
- Hardware identifiers
|
|
- System configuration
|
|
- Weather data from geographically random locations
|
|
|
|
2. **Dynamic Entropy Sources**:
|
|
- Current timestamp
|
|
- CPU and memory usage
|
|
- Process and thread information
|
|
- Network statistics
|
|
|
|
All sources are combined, hashed, and processed to create seeds for the random number generator that selects the lottery numbers.
|
|
|
|
## Testing
|
|
|
|
Unit tests are included to verify the functionality of all major components.
|
|
|
|
### Running Tests
|
|
|
|
Run the test suite with pytest:
|
|
|
|
```bash
|
|
python -m pytest test/
|
|
```
|
|
|
|
For a coverage report:
|
|
|
|
```bash
|
|
python -m pytest --cov-report term --cov=./fdj_slayer test/
|
|
```
|
|
|
|
## Configuration
|
|
|
|
Edit the constants in ``src/constants.py`` to modify:
|
|
|
|
| Parameter | Description |
|
|
|------------------------|-------------------------------------------------------|
|
|
| `NUMBER_OF_DRAWS` | Number of draws to generate |
|
|
| `NUMBER_OF_NUMBERS` | Number of main numbers in a draw (5 for EuroMillions) |
|
|
| `MAX_NUMBER` | Maximum main number value (50 for EuroMillions) |
|
|
| `NUMBER_OF_STARS` | Number of star numbers in a draw (2 for EuroMillions) |
|
|
| `MAX_STAR` | Maximum star number value (12 for EuroMillions) |
|
|
| Weather API parameters | Configuration for the OpenMeteo API |
|
|
|
