AUUGN Vol 5 No 3 Editorial Well, if the number of phone calls and letters that I receive is anything to go by, interest in UNIX is really hotting up. We now have nearly 200 subscribers, up from 30 at the beginning of volume 5, and 580 people on the mailing list. AUUG Meeting in Melbourne The preliminary announcement for the Melbourne AUUG meeting has been mailed out, but for those who may have missed out, here are a few details. The 1984 Winter meeting of the AUUG will be held at the University of Melbourne on Monday August 27 and Tuesday August 28. Keynote speaker for the conference will be Rob Pike, from AT&T Bell Laboratories, co-author of the book "The UNIX Programming Environment". Papers on any subject related to the UNIX system, or UNIX-like systems will be considered for the meeting. Prospective authors should send a detailed abstract (approximately a page) of their talk to Robert Elz, at the address below, before July i. Vendors desiring to display equipment should also contact Robert Elz as soon as possible to reserve space° Space will be allocated on a first come first served basis, and those who request early will obtain prime positions. Vendors should provide details of space, power and any other special requirements with their application. Charges will be based on facilities allocated and will be set individually for each display. A final announcement will be mailed to people on the AUUG mailing list early in July. Registrants seeking early registration discounts, or reserved accommodation in University Colleges, should reply by August i, 1984.

I plan to keep twisting, so watch out! Opinions expressed by authors and reviewers are not necessarily those of the Australian UNIX Users Group, its Newsletter or the editorial committee. Vol 5 No 3 AUUGN Books Does anyone out there know who publishes "A Programmer’s Guide to UNIX", "A Business Guide to the UNIX System", "A Programmer’s Guide to Xenix" and "A Business Guide to the Xenix System"? All are written by Jean Yates and Rebecca Thomas. Hopefully complete information will be available by next issue but for the moment, add the following to your list. Related Books 5. Pascal Under UNIX J.N.Po Hume and RoCo Holt Reston Publishing Company I also have not one, but TWO book reviews. Peter Mason has reviewed "Programming in C" by Stephen G Kochan, and Damian McGuckin has reviewed "Starting With UNIX" by P. Jo Brown. If you want to review some books, drop me a line. A Review of "Programming in C" by Stephen G. Kochan Hayden Book Company, Inc. Copyright 1983 by Stephen G. Kochan. Reviewed by Peter J. Mason Australian Graduate School of Management This is a book of rather large dimensions, 17.5cm by 24cm, and its 373 pages give a thickness of 2.5cm. It’s pages open out fully and the book can be made to stay open without too much trouble, making study from it easy. Soft covered and moderate grade paper shouldn’t make it too expensive. Unfortunately, no clues to the price came with the review copy, so value is something on which I am unable to comment. l’d like to have had a text such as this when I was learning C. It treats the language as just another language with no particular reference to UNIX, though the operating system does get mentioned in the Introduction and several Appendices. It should be equally applicable to programming under any other operating system. The book is most definitely for the novice and intended for classroom use with possibly a dozen or more exercises at the end of each chapter. Much effort has been put into giving good explanations in the body of the chapters, but this does not seem to have flowed over to the exercises with the same enthusiasm. The exercises are frankly boring. They range from "compare the output", and "modify the function", through to "write a program" type questions. For the most part, theyPre uninspiring, but do exercise aspects from their respective chapters. All features of the language are investigated with (in most cases) sufficiently wordy explanation to satisfy the curious student, though of necessity, several forward references are made to tantalize at times. The AUUGN Vol 5 No 3 back cover tells me that there are over 90 examples included in the volume. These appear to demonstrate most of C’s wonders and quirks. This is not a text to inspire good programming habits and well structured design, but as a first course in C it is adequate. Each chapter handles one aspect of C and the challenge to write large programs is not made at all. Data structures beyond the most primitive may infuse the imagination while working through it, but it will be up to the lecturer to enforce some implementation of them° I would like to present the table of contents here complete with beginning page numbers° This should yield some idea of the space devoted to ~ each. i Introduction i 2 Some Fundamentals 4 3 Writing a Program in C i0 4 Variables, Constants, Data Types, and Arithmetic Expressions 17 5 Program Looping 34 6 Making Decisions 53 7 Arrays ~80 8 Functions 99 9 Structures 138 i0 Character Strings 162 ii Pointers 196 12 Operations on Bits 234 13 The Preprocessor 254 14 More on Data Types 271 15 Working with Larger Programs 279 16 Input and Output 285 17 Miscellaneous Features and Advanced Topics 308 Appendix A Language Summary 321 Appendix B Common Programming Mistakes 351 Appendix C The UNIX C Library 355 Appendix D Compiling Programs under UNIX 363 Appendix E The Program LINT 367 Appendix F The ASCII Character Set 368 Index 369 In summary, we have a good, very easy to read text for its purpose, being to familiarize to reader with the language C. The strength of the book lies in its easy readability. Does this sound like the book for you? It’s a text book rather than a reference book, and excellent reading for the learner. Vol 5 No 3 AUUGN A Review of "Starting with UNIX" PoJo Brown Addison Wesley (1984) Reviewed by Damian McGuckin, Department of Civil Engineering Materials, University of New South Wales. Even though this book is aimed at beginners, it is one of those books which everybody should/must read at least once. It is not the sort of book on UNIX which would be kept as a reference, but definitely something everyone could use at some stage when dealing with UNIX. Unlike many books which give a detailed account of how to use UNIX, this book spends a lot of time going into the ideas and concepts behind UNIX. At the same time, it highlights the philosophy or way of thinking one should use to get the most out of UNIX. The author still raises the small-is-beautiful concept of UNIX, a feature that some argue is going out of vogue in the UNIX community of today. Finally, armed with this, one can then go out and (hopefully) use UNIX effectively, or maybe more effectively than one has in the past. The book begins with covering such basic concepts as timesharing systems in general, files, the UNIX file system and the command interpreter. It then goes into more detail on the shell sh, the editor ed, the online manual, communication between users and document preparation. These are adequately documented with various "SAMPLE SESSIONS". There is a short cursory section on program development covering cc, pascal, f77, lint, make and basic although cursory is the operative word in this chapter of 12 pages, 2 of which are code examples. There is an excellent chapter on problems one encounters when using UNIX. It covers such areas as the affect of a system crash and what to do after it, hung terminals, screenfuls of garbage, what to do if caught in a program which seems to ignore interrupts, and what to do when encountering the (sometimes cryptic) UNIX error messages. Finally, there is the mandatory appendix with a short list of fundamental UNIX commands. One could argue about the order in which certain topics are raised, (the editor appears halfway through the book), but in general this is really a book that needs to be read cover to cover and then read selectively to get the bits out of it that are wanted.

Olson Bren Professor of Information and Computer Sciences Department of Informatics Donald Bren School of Information and Computer Sciences 949-824-0080 [email protected] Gillian R. Hayes Assistant Professor Department of Informatics Donald Bren School of Information and Computer Sciences 949-824-1483 [email protected] November 19, 2012 1 Introduction 1.1 Aims and Objectives This proposal represents a natural evolution in the field of Informatics (elsewhere called Information or Information Science), a broad term covering a host of subspecialties, including human-computer interaction, social informatics, information economics, information policy, and library and archival science. Complementing our existing offerings, we propose to offer a Ph.D. in Informatics in the Department of Informatics to signify the recognizable “flavor” of the field of study we offer. Until recently, the department offered four tracks within the Informatics concentration of the ICS Ph.D.: • Informatics – General • Informatics – Track in Interactive and Collaborative Technology • Informatics – Track in Ubiquitous Computing • Informatics – Track in Software Engineering A Ph.D. degree in Software Engineering has now been added, replacing the degree currently called Informatics—Track in Software Engineering. This proposal specifies the Ph.D. in Informatics, replacing the three remaining tracks (Informatics- General, Informatics-ICT and Informatics-Ubiquitous Computing). The new arrangement (two PhDs, one in Software Engineering and one in Informatics) mirrors our undergraduate offerings (two B.S. degrees, one in Software Engineering and one in Informatics.) In contrast to our current Ph.D. offering in Information and Computer Science, we believe that the naming of the Ph.D.

  • Software Inspections at Nasa Ames
    N86-.. 30363 Oualitv Assurance Software Insoections at NASA Ames Metrics for Feedback and Modification Greg Wenneson, Informatics General Corporation Software Inspections are a set of formal technical review procedures held at selected key points during software development for the purpose of finding defects in software documents. Inspections are a Quality Assurance tool and a Management tool. Their primary purposes are to improve overall software system quality while reducing lifecycle costs and to improve management control over the software development cycle. The Inspections process can be customized to specific project and development type requirements and are specialized for each stage of the development cycle. For each type of Inspection, materials to be inspected are prepared to predefined levels. The Inspection team follows defined roles and procedures and uses a specialized checklist of common problems in reviewing the materials. The materials and results from the Inspection have to meet explicit completion criteria before the Inspection is finished and the next stage of development proceeds. Statistics, primarily time and error data, from each Inspection are captured and maintained in a historical database. These statistics provide feedback and feedforward to the developer and manager and longer term feedback for modification and control of the development process for most effective application of design and quality assurance efforts. HISTORY Software Inspections were developed in the early mid-1970s at IBM by Dr. Mike Fagan, who was subsequently named software innovator of the year. Fagan also credits IBM members O.R.Kohli, R.A.Radice and R.R.Larson for their contributions to the development of Inspections.
