I wrote a game in Labview once. I took me 2 days to learn to program in Labview. I did a software radio project two years ago and had it up and running in 3 days. The team then took the program and tried to rewrite it using C+. Three months later they gave up; Labview ran faster, and crashed less.

Names convey meanings; our choice of names determines the meaning of what we say. An inappropriate name gives people the wrong idea. A rose by any other name would smell as sweet—but if you call it a pen, people will be rather disappointed when they try to write with it. And if you call pens “roses”, people may not realize what they are good for. If you call our operating system Linux, that conveys a mistaken idea of the system's origin, history, and purpose. If you call it GNU/Linux, that conveys (though not in detail) an accurate idea.
