Take 5 minutes to enjoy this satirical ride with Grey Lens Man [1] as he takes you through the very real challenge he faced bringing new technology into a large company. He starts with "You see, I have a small problem - 3 million lines of RPG and COBOL, 5,500 logical and physical files on a few AS400s" and it has got to be replaced. He reveals the magnitude of the beast and explains how the group set about slaying it; the heresy of using Scala; how Java programmers came to like it. And an in-the-face reminder that "he who dares wins". You will see the solution to a current problem, but much more valuable, the insight and tools he plans to use for solving the next ones too. And it's just plain fun!
