"..Gamma encoding of images is required to compensate for properties of human vision - to maximize the use of the bits or bandwidth relative to how humans perceive light and color. Human vision under common illumination conditions (not pitch black or blindingly bright) follows an approximate gamma or power function. If images are not gamma encoded, they allocate too many bits or too much bandwidth to highlights that humans cannot differentiate, and too few bits/bandwidth to shadow values that humans are sensitive to and would require more bits/bandwidth to maintain the same visual quality. Gamma encoding of floating point images is not required (and may be counterproductive) because the floating point format already provides a pseudo-logarithmic encoding. A common misconception is that gamma encoding was developed to compensate for the input–output characteristic of cathode ray tube (CRT) displays.. But in fact, the gamma characteristics of the display device do not play a factor in the gamma encoding of images and video—they need gamma encoding to maximize the visual quality of the signal, regardless of the gamma characteristics of the display device. The similarity of CRT physics to the inverse of gamma encoding needed for video transmission was a combination of luck and engineering which simplified the electronics in early television sets.."
"dd copies a file (from standard input to standard output, by default) with a changeable I/O block size, while optionally performing conversions on it.. The only options are --help and --version.. dd accepts the following operands.."
Banks create money as debt (loans). The interest required on these is not created. Hence the scarcity of money & consequent spiralling "Robbing Peter to pay Paul". Competition, family breakdown, war.
"This website is dedicated to providing you with resources to educate yourself about currency. We hope you will find space in your busy life to ponder deeply what kinds of economic relationships you wish to be in. Conventional money is just one way to measure wealth. How will you measure the wealth you create?"

"If these are the labels that you stick onto a dvd ..then IMO I wouldn't bother as these can make your discs unplayable. You are better off printing straight onto a printable dvd.. when a disc with this sort of label applied , when it becomes hot the label can start to peel at the edges and become unbalanced, it may even stick in your drive.."
"..the name "government-letter" was given by the IEEE Printer Working Group: the 8 × 101⁄2 in (203.2 × 266.7 mm) paper that is used in the United States and Canada for children's writing. It was prescribed by Herbert Hoover when he was Secretary of Commerce to be used for U.S. government forms, apparently to enable discounts from the purchase of paper for schools. In later years, as photocopy machines proliferated, citizens wanted to make photocopies of the forms, but the machines did not generally have this size paper in their bins. Ronald Reagan therefore had the U.S. government switch to regular letter size (81⁄2 × 11 in/215.9 × 279.4 mm). The 8 × 101⁄2 in (203.2 × 266.7 mm) size is still commonly used in spiral-bound notebooks and the like.."
