Development Insights
Challenges & Solutions
Resource Management
The primary challenge was ensuring proper cleanup of system resources across different processes. I solved this by implementing comprehensive RAII patterns and cleanup procedures.
Synchronization
Coordinating multiple processes required careful synchronization. I addressed this by using POSIX semaphores and implementing a robust flow control system.
Memory Safety
Working with shared memory required careful attention to memory safety. I implemented bounds checking, proper memory mapping, and thorough error handling to ensure safe operations.
