JBIG2 is an image compression standard for bi-level images, developed by the Joint Bi-level Image Experts Group. It is suitable for both lossless and lossy compression. According to a press release from the Group, in its lossless mode JBIG2 typically generates files one third to one fifth the size of Fax Group 4 and one half to one quarter the size of JBIG, the previous bi-level compression standard released by the Group. JBIG2 has been published in 2000 as the international standard ITU T.88, and in 2001 as ISO/IEC 14492.

Ideally, a JBIG2 encoder will segment the input page into regions of text, regions of halftone images, and regions of other data. Regions which are neither text nor halftones are typically compressed using a context-dependent arithmetic coding algorithm called the QM coder. Textual regions are compressed as follows: the foreground pixels in the regions are grouped into symbols. A dictionary of symbols is then created and encoded, typically also using context-dependent arithmetic coding, and the regions are encoded by describing which symbols appear where. Typically, a symbol will correspond to a character of text, but this is not required by the compression method. For lossy compression the difference between similar symbols (e.g., slightly different impressions of the same letter) can be neglected; for lossless compression, this difference is taken into account by compressing one similar symbol using another as a template. Halftone images may be compressed by reconstructing the grayscale image used to generate the halftone and then sending this image together with a dictionary of halftone patterns. An overview of JBIG2 may be found in. Overall, the algorithm used by JBIG2 to compress text is very similar to the JB2 compression scheme used in the DjVu file format for coding binary images.

Richard Thieme (born 1944), is a noted business consultant, author, media commentator and speaker.

Richard Thieme was born in Chicago. He graduated from Northwestern University in 1965 with a B.A. in English literature. He later earned a M.A. in English at the University of Chicago, where he studied with noted Joycean scholar Richard Ellmann. Thieme spent two years in England, then returned to Chicago to attend Seabury-Western Theological Seminary, where he earned his Masters of Divinity degree and became an Episcopal priest.

Thieme was a priest for 16 years, during which he became acquainted with computers. He began writing about technology and culture, including the spiritual dimension of technology. In 1993, he began a new career of consulting, writing and speaking. He has spoken often at the Def Con and Blackhat Briefings security conferences, where he would introduce himself by pointing out that his experiences as a priest made him "more than qualified to talk about social engineering".

Sean Michael Maurice Taylor (April 1, 1983 – November 27, 2007) was an American college and professional football player who was a free safety for the Washington Redskins of the National Football League (NFL) for four seasons. Taylor was drafted in the first round (fifth overall) of the 2004 NFL Draft by the Redskins. He played college football for the University of Miami, was a member of the Hurricanes' 2001 BCS National Championship team, and earned consensus All-American honors. Due to his ferocious hits, several of his pro teammates nicknamed him "Meast," a portmanteau word from the expression "half man, half beast."

Taylor died at the age of 24 on November 27, 2007, from critical injuries due to gunshots by intruders at his Miami area home. His death led to an outpouring of national support and sympathy, especially in the Washington area, where Taylor had been a fan favorite as a Redskin, and the Miami area, where Taylor had starred for the Miami Hurricanes, after leading Gulliver Prep to a Florida state high school championship and setting a state record for most touchdowns in a season (44).
