To help you craft a prompt for deep self-research across public information sources or AI knowledge bases, here's a structured approach and guidance on the details to include.

Your Self-Research Prompt Template

"Please conduct a comprehensive deep-dive research on [Your Full Name]. Focus on gathering publicly available information across various online platforms, historical records (if applicable and public), and any associated data within your knowledge base.

Prioritize information that reveals:
1.  **Professional Presence:** Roles, companies, projects, publications, presentations, patents, open-source contributions, and any publicly recognized achievements.
2.  **Academic Background:** Educational institutions, degrees, notable academic projects, research papers, or certifications.

	# Global Rate Limiting Settings
	# These settings define how Nginx will manage the rate of incoming requests across all services.

	# Increase the maximum number of memory map areas a process may have.
	# This helps prevent out-of-memory errors for applications like Nginx that handle many connections,
	# each potentially requiring its own memory mappings. Your value of 262144 is well-suited.

	# Increase the maximum number of file handles available system-wide.
	# Nginx, especially as a reverse proxy or load balancer, opens a large number of file descriptors
	# for incoming client connections, outgoing backend connections, log files, and cached content.
