When applications fail under heavy load or suffer from mysterious memory leaks, treating the operating system as a black box is no longer an option. To build truly scalable and resilient software, you must cross the boundary between user space and kernel space.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eEssential System Calls Explained\u003c\/b\u003e is a definitive guide designed to transition competent application developers into expert systems programmers.
