It's does not take a huge amount of knowledge and skill to get a program working.Kids in high school do it all the time. young men and women in college start billion-dollar business based on scrabbling together a few lines of PHP or Ruby. Hoards of junior programmers in cube farms around the world slog through massive requirements documents held in huge issue tracking systems to get their systems to "work" by the sheer force of will. The code they produce may not be pretty; but it works. It works because getting something to work-once-just is not that hard.
