We just finished our 5th annual Hacking for Defense class at Stanford.\n\nWhat a year.\n\nAt the end of the quarter each of the eight teams give a final \u201cLessons Learned\u201d presentation. Unlike traditional demo days or Shark Tanks which are, \u201chere\u2019s how smart I am, please give me money,\u201d a Lessons Learned presentation tells the teams\u2019 stories of a 10-week journey of hard-won learning and discovery. For all the teams in a normal year it\u2019s a roller coaster narrative of what happens when you discover that everything you thought you knew on day one was wrong and how they eventually got it right.
