software safety

HAZOP (Hazard and Operability Study) was originally developed for the chemical process industry, where facilities routinely handle hazardous materials. In such environments, even small malfunctions in manufacturing processes can lead to serious safety incidents. The methodology was first developed in 1961 as a structured way to systematically identify hazards and operability issues in complex industrial processes. Over time, the approach matured and was formally standardized

The previous blog post examined how memory management deficiencies can lead to safety hazards in mission-critical systems. This article focuses on methods and design practices that help prevent or mitigate such failures. How to solve memory issues? Practical defenses that work Memory safety isn’t solved by one magic tool or one “best practice.” In mission-critical embedded systems, the reliable approach is layered defense: good design choices first, then disciplined coding,

How memory management can turn into real safety hazards   In mission-critical embedded systems, think automotive ECUs, avionics controllers, medical devices, industrial safety PLCs, memory safety is not a “nice-to-have.” It’s a reliability and safety requirement. A single memory bug can cause a watchdog reset, corrupt sensor readings, flip a state machine into the wrong mode, or silently degrade behavior over time. In safety terms, that means a software defect can become a ha

What are Embedded Systems? Before diving into Python's role, let's establish what embedded systems actually are. An embedded system is a specialized computer designed to perform specific tasks within a larger system. Unlike your laptop or smartphone, which runs many different applications, an embedded system typically does one job and does it reliably for years. You'll find embedded systems everywhere: in your car's braking system, your microwave, medical devices, and industr
