oder Best Practices

### Sicherheit
- Prüfsummen beim Herunterladen immer überprüfen
- Verwenden Sie starke Authentifizierungsmethoden
- Regelmäßig auf die neueste Version aktualisieren
- Prinzip der Mindestberechtigung

### Performance
- Verwenden Sie entsprechende Puffergrößen
- Ressourcennutzung überwachen
- Optimieren Sie die Konfiguration für Ihren Anwendungsfall
- Regelmäßige Wartung und Reinigung

### Wartung
```bash
# Update gem
gem update

# Clean temporary files
gem clean

# Backup configuration
gem backup --config

# Restore from backup
gem restore --config <backup-file>
```_

Integration

### Scripting
```bash
#!/bin/bash
# Example script using gem

# Check if gem is available
if ! command -v gem &> /dev/null; then
    echo "gem is not installed"
    exit 1
fi

# Run gem with error handling
if gem <command>; then
    echo "Success"
else
    echo "Failed"
    exit 1
fi
```_

### API Integration
```python
# Python example
import subprocess
import json

def run_gem(command):
    try:
        result = subprocess.run(['gem'] + command.split(),
                              capture_output=True, text=True)
