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.
"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.
| # --- General System Resource Limits --- | |
| # 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. | |
| vm.max_map_count = 262144 | |
| # 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. |

| # Global Rate Limiting Settings | |
| # These settings define how Nginx will manage the rate of incoming requests across all services. | |
| # 'warn' log level means only significant events (like requests being limited) are logged. | |
| # The 'global' zone tracks requests based on client IP, allowing 10 requests per second. | |

| # --- HTTP Traffic Handler (Port 80) --- | |
| # This section defines how Nginx processes standard, unencrypted web requests on port 80. | |
| # It's intended for traffic forwarded by a load balancer, potentially after SSL termination. |
