testing notes from go

Lessons learned testing in Go

  • components should be silent when on the road, noisy when manufacturing

    • log/printf for debugging as you develop

  • use testing to help eliminate noise as your components are built

    • look at test output, when everything reads PASS, everything should be quiet. That means no more remaining log/printf output!

  • good unit tests help eliminate noise; less noise = more coverage!

ftd

ftd

ftd aims to be a tool for drawing text-based diagrams in the same vein as OmniGraffle, Visio, and Monodraw. It should provide a UI that is WYSIWYG and should be "pixel perfect."

Desiderata

Software

  1. Must be cross-platform and support Desktop Linux/Windows/Mac. The UI must be consistent across all platforms.
  2. Must be released in source and binary form as public domain (i.e. prevent crippling from the bondage of licensing).
