Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Lee Daniel Crocker is an American computer programmer and poker player. He is best known for rewriting the software upon which Wikipedia runs to address scalability problems. This new software, originally known as "Phase III," went live in July 2002 and became the foundation of what is now called MediaWiki. Today, MediaWiki's Subversion code repository is still named "phase3." He was involved in the creation of the GIF, JPEG, and PNG image file formats, and appears as a co-author of the PNG specification. He invented the per-scanline variable pre-filtering compression method used by PNG, the sum-of-abs heuristic used by many encoding programs, and proposed an early version of the Adam7 algorithm, using 5 passes rather than 7.show more
