“It’s not about
the code you
write, it’s about
the code you
live by.”

A decade ago, the programming industry was nothing like it is today. We found an opportunity to shine a spotlight on an industry largely in the dark.

Excerpt from “Defining The Modern-Day Programmer”

“I am a nonaccredited, overly logical psychologist, therapist, mechanic, diplomat, businessman, working in an industry that is still defining itself each and every day. That is as concise a definition I can give for the modern-day programmer.”

Derek Sivers
