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…

Secure Avionics Update: Patch Management and Safe Software Delivery for Airborne Systems
Updating avionics software is not a routine maintenance task it is a high-stakes engineering operation where any failure can compromise safety, mission capability, and regulatory compliance. Modern aircraft rely on increasingly complex digital components, and keeping these systems secure and up to date requires a tightly controlled patch-management pipeline built around cryptographic trust, verification,…
