A 40-year embedded systems veteran shares personal guiding principles for engineers, blending classic quotes from Feynman, Edison, and others with hard-earned aphorisms. Key themes include evidence-based thinking, testing rigorously (untested code is broken by definition), instrumenting systems for data, planning for contingencies, lifelong learning, the hacker mentality, and maintaining honesty and integrity. The principles apply broadly to developers, managers, and executives across disciplines.
