What is the windows variation to those/Instruments.app? (generally speaking, I am aware that it might not apply to debugging node apps running on top of cygwin)
This is a completely philosophical discussion, but I do not think blueprints can be the code, since blueprints in every other industry still leave a degree of freedom for the final implementation and in the software industry code IS the final implementation.
It was hard for the skunk works teams to use UML for a long time since it was only published in the late 90's, but what makes you so sure they are not using it now? or do you have a survey of which "good things" are not designed in this fashion?
And besides what is the relative share of skunk works type teams from the overall software development market?
