Deep dives
Understanding Operating System Fundamentals
The efficient operation of modern software relies heavily on a deep understanding of operating system kernels. Engineering practices can greatly improve when software developers grasp how the kernel orchestrates processes such as memory access and data management. For example, accessing or writing data prompts the kernel to engage in a series of complex interactions between software and hardware, which can introduce unexpected performance costs. By demystifying kernel operations, developers can write more efficient code and approach programming with a mindset that questions the implications of each coding decision.
