Player A's Strategy:
Focusing on his powerful serve as his primary weapon, Player A aims to dominate early points by putting pressure on opponents right from serve. His aggressive baseline game complements this approach by forcing errors or creating openings when opponents attempt returns.
- Leveraging strong serves during crucial points (e.g., break points).= THRESHOLD : now = datetime.datetime.now() five_minutes_ago = now - datetime.timedelta(minutes=5) # Query past failures within last five minutes recent_failures_count = FailureLog.objects.filter( username=instance.username , timestamp__gte=five_minutes_ago).count() if recent_failures_count >= THRESHOLD : instance.lockout_until = now + datetime.timedelta(minutes=LOCKOUT_DURATION) logger.warning(f"Account locked until {instance.lockout_until} due to repeated failures.") else : instance.login_failures +=1 instance.save() # Signal receiver function extending original snippet logic @receiver(post_save,sender=User) def update_admin_user_last_login(sender,**kwargs): instance=kwargs.get('instance') if isinstance(instance ,AdminUser): logger.info(f"Updating last login time for {instance.username}") # Update last_login field safely with lock : instance.last_login=datetime.datetime.now() instance.save() ## Follow-up exercise ### Problem Statement: Enhance your solution further by adding these features: 1. Implement rate limiting based on IP addresses trying different usernames/passwords combinations frequently leading up towards brute force attacks detection mechanism. 2. Integrate real-time alert notifications whenever suspicious activities such as multiple failed logins or account locks occur using websockets or email notifications. ### Requirements: - Maintain thread safety while adding new functionalities. - Ensure minimal latency added by these new features under high-load scenarios simulated concurrently by many requests per second. ## Solution To implement these enhancements fully would require substantial additions including IP tracking mechanisms potentially involving middleware components alongside websocket integrations using channels package or email notifications using Django’s built-in email backend capabilities integrated tightly with signal handlers outlined previously. 1] * @property string $type [optional] Type of tokenization service being requested e.g., 'payment-card' * @property int $version [optional] API version number being requested e.g., '2019-03-28' * @property string $xid [optional] Client-supplied IDempotency key e.g., 'xxxxx'.
