Summary

This blog by Miro Samek examines how metaphors and mental models shape the way engineers design software, especially in embedded and resource-constrained systems. Readers learn why particular metaphors (objects, state machines, pipelines, actors) succeed or fail in firmware, RTOS, and bare‑metal contexts and how to choose clearer models for safer, simpler designs.

Key Takeaways

• Recognize common programming metaphors and their implicit assumptions when applied to embedded systems
• Map high-level metaphors (objects, actors, pipelines) onto concrete firmware constructs like ISRs, tasks, and state machines
• Apply better mental models to simplify concurrency and interaction in RTOS and bare‑metal designs
• Avoid misleading metaphors that cause inefficiency, fragility, or incorrect resource assumptions in embedded code

Who Should Read This

Intermediate firmware and embedded engineers, architects, or engineering leads who design or review low-level software and want clearer mental models to improve design decisions and maintainability.
