    Answers to Exercises A bird does not sing because he has an answer, he sings because he has a song. —Chinese Proverb Intro.1: abstemious, abstentious, adventitious, annelidous, arsenious, arterious, face- tious, sacrilegious. Intro.2: When a software house has a popular product they tend to come up with new versions. A user can update an old version to a new one, and the update usually comes as a compressed file on a floppy disk. Over time the updates get bigger and, at a certain point, an update may not fit on a single floppy. This is why good compression is important in the case of software updates. The time it takes to compress and decompress the update is unimportant since these operations are typically done just once. Recently, software makers have taken to providing updates over the Internet, but even in such cases it is important to have small files because of the download times involved. 1.1: (1) ask a question, (2) absolutely necessary, (3) advance warning, (4) boiling hot, (5) climb up, (6) close scrutiny, (7) exactly the same, (8) free gift, (9) hot water heater, (10) my personal opinion, (11) newborn baby, (12) postponed until later, (13) unexpected surprise, (14) unsolved mysteries. 1.2: A reasonable way to use them is to code the five most-common strings in the text. Because irreversible text compression is a special-purpose method, the user may know what strings are common in any particular text to be compressed. The user may specify five such strings to the encoder, and they should also be written at the start of the output stream, for the decoder’s use.

There have been many significant events that need announcing. The highlights are: Release 2 of PASCAL 6000-3.4 has beeh made available by Dr. Urs Ammann at Eiqgenossische Technische Hochschule in Zurich, Switzerland. It is also available from Mr. George Richmond at the University of Colorado Computing Center in Boulder, Colorado and Mr. Carroll Morgan at the Basser Department of Computer Science, University of Sydney, Australia. Many improvements have been made over Release 1 and future developments are promised. See page 73. Mr. Carroll Morgan of the Basser Department of Computer Science at the University of Sydney, Australia has kindly agreed to distribute ETH Pascal and portable Pascal for Australia and neighboring regions. Interested parties should contact Mr. Morgan for more informa~ion. Mr. Andy Mickel of the University of Minnesota kindly agreed to take over editorial control and publication of the Pascal Newsletter commencing wi'th issue Number 5 in September 1976. He is also organizing a User's Group. See pages 88 and 89. An improved portable Pascal has been released from ETH, , zur ich. See page 81. News of Pascal compilers for numerous machines has been received. See pages 96 and following. An expanded bibliography .of Pascal literature has. been compiled. See pages 100 and following. I have enjoyed producing the first four newsletters but I have found it to be very time consuming. I am grateful to Andy for taking over these duties with enthusiasm.

  • Appendix a Information Theory
    Appendix A Information Theory This appendix serves as a brief introduction to information theory, the foundation of many techniques used in data compression. The two most important terms covered here are entropy and redundancy (see also Section 2.3 for an alternative discussion of these concepts). A.1 Information Theory Concepts We intuitively know what information is. We constantly receive and send information in the form of text, sound, and images. We also feel that information is an elusive nonmathematical quantity that cannot be precisely defined, captured, or measured. The standard dictionary definitions of information are (1) knowledge derived from study, experience, or instruction; (2) knowledge of a specific event or situation; intelligence; (3) a collection of facts or data; (4) the act of informing or the condition of being informed; communication of knowledge. Imagine a person who does not know what information is. Would those definitions make it clear to them? Unlikely. The importance of information theory is that it quantifies information. It shows how to measure information, so that we can answer the question “how much information is included in this piece of data?” with a precise number! Quantifying information is based on the observation that the information content of a message is equivalent to the amount of surprise in the message. If I tell you something that you already know (for example, “you and I work here”), I haven’t given you any information. If I tell you something new (for example, “we both received a raise”), I have given you some information. If I tell you something that really surprises you (for example, “only I received a raise”), I have given you more information, regardless of the number of words I have used, and of how you feel about my information.

Strecok National Energy Software Center Argonne National Laboratory Argonne, IL 60439 The National Energy Software Center (NESC) is c software exc!'ange and information center operated by Argonne National Laboratory for the U. S. Department of Energy (DOE), with support from the Nuclear Regulatory Commission. The major objectives of the NESC program are: o to promote the sharing of co=puter software among agency offices and contractors, o to facilitate the transfer of agency-developed conputer applications and technology to the information processing co=munity, and o to provide the focal point for DOE software exchange arrangements with other government agencies and for coordination of DOE acquisition of non-government software. HISTORY The Center is the successor to the Argonne Code Center, originally established by the U. S. Atomic Energy Co==ission in 1960 in response to a proposal by the Mathematics and Computation Division of the American Nuclear Society for a center dedicated to the collection and exchange of information on nuclear reactor codes. The Code Center operated initially as an adjunct to the Laboratory's Applications Programming activity, utilizing the major computer manufacturers' library facilities for , reproduction and distribution of designated program package material, and professional society services for disse =ination of abstracts describing the , software collection and other information. Beginning in 1965 the Reactor i Physics Branch of the AEC's Division of Reactor Development and Technology provided the direct funding to permit .he development of independent Center sof tware library ar.d information dissemination capabilities.
