Developer Happiness and why it matters
summary
Research shows deep focus matters: one meeting = 99% chance of feeling progress, two meetings = 75%, and three meetings = 14%, so blocking uninterrupted time drastically improves outcomes. Tooling lowers cognitive load: GitHub Codespaces and Dev Containers cut onboarding from ~45 minutes to under a minute, GitHub Copilot reduces keystrokes and explains code, and CI/automated tests tighten feedback loops. A 5‑minute end‑of‑day reflection also meaningfully raises the likelihood of calling it a good day.
