1
Writing code that interacts directly with the operating system kernel, bypassing standard user-space APIs. This is necessary for drivers, custom file systems, or performance monitoring tools. It demands expert knowledge of memory management, concurrency primitives, and the specific kernel ABI. Error...

This involves writing code that interacts directly with hardware memory addresses, managing interrupts, and implementing core OS primitives (scheduling, memory management). It is the pinnacle of systems programming difficulty. While offering ultimate control and performance, debugging requires speci...
