GIF was one of the first two image formats commonly used on Web sites, the other being the black-and-white XBM. [5] In September 1995 Netscape Navigator 2.0 added the ability for animated GIFs to loop. While GIF was developed by CompuServe, it used the Lempel–Ziv–Welch (LZW) lossless data compression algorithm patented by Unisys in 1985.
The header often contains a signature or magic number which can identify the format. For example, a GIF file can contain multiple images, and headers are used to identify and describe each block of image data. The leading bytes of the header would contain text like GIF87a or GIF89a that can identify the binary as a GIF file.
Magic numbers become particularly confusing when the same number is used for different purposes in one section of code. It is easier to alter the value of the number, as it is not duplicated. Changing the value of a magic number is error-prone, because the same value is often used several times in different places within a program. [6]

The original "up to eleven" knobs in the 1984 film This Is Spinal Tap "Up to eleven", also phrased as "these go to eleven", is an idiom from popular culture, coined in the 1984 film This Is Spinal Tap, where guitarist Nigel Tufnel demonstrates a guitar amplifier whose volume knobs are marked from zero to eleven, instead of the usual zero to ten.
The Numbers Do Lie. Drake London’s WR23 PPG rank was a lie. A huge Week 18 padded his stats, but London was the WR23 in fantasy points per game during the fantasy season (Weeks 1-17), so he ...
Common raster compression algorithms include run-length encoding (RLE), JPEG, LZ (the basis for PNG and ZIP), Lempel–Ziv–Welch (LZW) (the basis for GIF), and others. For example, Run length encoding looks for repeated values in the array, and replaces them with the value and the number of times it appears.
