Towards Joyful Development
summary
Argues that tightening feedback loops—more small, hermetic unit tests, fewer brittle end-to-end Appium/Selenium tests, and parallelized builds—returns frequent “green bar” dopamine hits and faster delivery. Recommends TDD/test-first, ports-and-adapters (aka hexagonal architecture) to swap fast local doubles for slow services, aims for a 10 second local build and 10 minute CI runs, uses Bazel-like incremental builds and distributed caches, treats feature flags and staged rollouts as deployment safety, and ruthlessly deletes flaky or unused tests.
