Professionalism definition from Uncle Bob in his recent talk at RailsConf 2009:

“Discipline to wielding of power.”

— Robert Martin (aka Uncle Bob)

To me, it looks pretty much similar to the “Ruby” definition from Chad Fowler in the last Rails Summit Brasil:

“Ruby is a dangerous tool.”

— Chad Fowler

Wich makes me remember Uncle Ben’s advice to Spider Man:

“With great power comes great responsibility.”

— Uncle Ben

Would be Uncle Bob inspired by Uncle Ben? What if they are the same person? 😀
