Duff’s Device Is a Lie. Here’s the Truth.

Duff’s Device is revered as the most elegant optimization in C history β€” a switch-case fused with a do-while loop to unroll iteration. But on the very systems it was designed for, it was often slower than the naive loop it replaced. The real lesson isn’t about cleverness. It’s about the discipline of benchmarking and the danger of revering patterns instead of measuring them.

Stop Reinventing the Wheel. Templates Are the Most Underrated Innovation Tool You Have.

Most engineering managers treat templates as bureaucratic noise. They’re wrong. The best templates aren’t compliance documents β€” they’re cognitive leverage. They handle the 80% of routine decisions so you can focus your real energy on the 20% that actually matters: judgment calls, team dynamics, and the problems no template can solve.

The Transistor Gets All the Credit. But Modern Computing Was Born in a Glowing Glass Bottle.

The transistor didn’t invent digital logic β€” it just made it cheaper. In 1948, IBM’s 604 system was already running reliable binary computation inside fragile, glowing vacuum tubes, using modular, field-replaceable components that pioneered the architecture behind every modern computer. The real breakthrough wasn’t silicon. It was the idea that logic could be wrestled from chaos.
