Crayon Drawing Is a Vital Engineering Skill
summary
Claim: quick, hand-drawn system overview diagrams produce shared understanding that speeds onboarding, debugging and design decisions. Examples: three compact views of a home network, a two-minute sketch of Google Traffic (GFE, maglev, gslb, 8888, frontends) and an Orion SDN diagram (ofe, flow manager, topology manager, NIB) are reproducible from memory and about 90% similar across teammates. Use low-friction tools—whiteboards, pen and paper, or mermaid.js / Dot / SVG—and favor memorable abstractions over exhaustive accuracy.
