I have that cartoon on my wall. I do so many software installs in the course of a day, you'd think a progress barr would become JAPB.
I prefer the minimal approach as well, and have often cursed M$ for their animated flying papers that wriggle and float from one folder to another.
For my part, not being a programmer, I have often wondered how the darned things work. Do they actually measure progress? Is it a percentage of the over all program size that's measured? Is it the percentage of the number of files that are to be installed? Does it measure the programmers' perceived notion of how long the install should take? Does it measure some sort of programmatic "marker" during the install, and then in turn updates the progress bar?
Maybe now someone will be able to answer these questions for me, and I can get on with more important things in my life, such as how they get the tiny grains of sand into that little hourglass, how close to the speed of light does my clothes washer goes on the spin cycle, or perhaps why my cat has a slice of buttered toast stuck her back....
I guess I'm still the retard everyone tells me I am.
