Cross-Kernel Processing Running Multiple Kernels Simultaneously on a Single System
Introduction Cross-Kernel Processing is not a cosmetic optimization it is a structural break from how operating systems have traditionally been designed. Instead of forcing one monolithic kernel to handle every workload type, Cross-Kernel allows multiple specialized kernels to run simultaneously on the same hardware, each optimized for a distinct responsibility. This approach directly targets…

Code Running on Living Metal When Hardware Stops Playing by the Rules
Software engineers love to believe their code runs in a clean, deterministic universe. But once you drop below the OS layer and step onto bare metal, that illusion collapses. Microcontrollers, avionics systems, and industrial controllers operate inside physics not logic and physics doesn’t care about your abstractions. 1. Hardware Is Not a Perfect Machine…

Kernel Locking and Concurrency Pitfalls in Operating Systems
In modern operating systems, concurrency isn’t optional — it’s fundamental. Multiple threads and processes access shared resources constantly: memory, I/O, scheduling queues, filesystem metadata. Without strict synchronization, the kernel becomes a war zone of race conditions, data corruption, and unpredictable crashes. The kernel sits at the lowest level of control. If a locking mistake…
