Book Reviewscomplex techniques. The book’s title tells you exactlywhat to expect. He shows you what is possible but tellsyou very little about how to do it. When he describesa particular way to present highly complex data usingcomputer software packages, he provides a footnotecontaining the URL for finding that software.Mazza’s examples are from computer presentationsof complex data. For example, he shows a way topresent computer usage by students in 345 onlineclasses on a single screen by conveying information forindividual courses at the pixel level and using color toindicate usage by the course. Presumably, one couldinsert a visual presentation into a document, but he doesnot address that issue.The book addresses what he sees as the mainproblem in designing a visual representation: “creatingvisual mapping that, on the one hand, faithfullyreproduces the information codified in the data and,on the other, facilitates the user in the predeterminedgoal” (p. 24). This emphasis on the user culminates inan entire chapter on evaluating the effectiveness of thevisual presentation. This chapter will be quite familiarto those who regularly do usability studies. While notspecifically adding anything new, its very presence in abook on visual representation is unusual.Mazza makes clear that the book is meant to be atextbook for a course in information visualization. Itcertainly would be an effective text for such a courseextending over 16 or 17 weeks, but the instructor wouldneed to add material, especially on how to actually createthe different visual types.As mentioned before, the final chapter exploresevaluation. Principally, the designer needs to evaluatethe presentation correctly so that it “can revealpotential problems and indicate which actions haveto be carried out to improve the quality of the visualrepresentation” (p. 132).I find this book highly useful in understandinghow to handle massive quantities of data visually. It isan introduction and, if used as a textbook, would needheavy supplementing. If used as a reference book, itpoints the way to solving problems related to visualrepresentation of data in real time. I think it a usefulbook for both academics and practitioners.Tom WarrenTom Warren is an STC Fellow, a winner of the Jay R.

Beyer. 2009. Cambridge, MA: The MIT Press. [ISBN 978-0-262-01310-9. 408 pages, including index. US$27.95.]In Grace Hopper and theInvention of the InformationAge, Beyer weaves U.S.history into Hopper’s lifein a book that is difficult toput down. Although I wasghostwriter on the collegetextbook published by WestPublishing Company in the1980s under Hopper’s name,I was unaware of the lastingimpact of the attack on PearlHarbor and the U.S. involvement in World War II onthe computer industry. Pearl Harbor created careeropportunities for women. At about that time, Hopperdivorced her husband, left her teaching position atVassar College, and joined the Navy.Beyer includes a humorous quote from Hopperregarding her adjustment to the Navy after her intenseteaching schedules at both Vassar and Barnard College.In the Navy, she found an environment where she wasrelieved of all minor decisions: “I just promptly relaxedinto it like a featherbed and gained weight and had aperfectly heavenly time” (p. 33).The early computers were used by the governmentto simulate rocket trajectories and the movementof ships. Although the Mark I—the first computingmachine used by the government—was thought to docalculations quickly, today’s laptop computer has thecapacity to process information 333 million times faster.The Mark I (also known as the Automatic SequenceControlled Calculator) was 51 feet long, weighed 9,445pounds, and had 530 miles of wiring. Manipulating thehardware of the early computing machines could bedangerous. Beyer notes that operator David Green was348 Technical Communication l Volume 57, Number 3, August 2010
Book Reviewsnearly strangled when his tie got caught in the sequencemechanism.Hopper is credited with finding the first computerbug. Since the windows at Harvard University didn’thave screens on them, bugs flew in. When the Mark IIstopped running, Hopper found a large moth with a4-inch wing span beaten to death in one of the relays.The workers used Scotch tape to add the corpse to thelog book on September 9, 1945.Beyer covers many details about Hopper, includingthe following:• Was among the first modern programmers.• Developed a system of documentation within eachsegment of code.• Developed COBOL.• Braved a hurricane in fall 1944 to work in theHarvard Computation Laboratory.• Used the vanity mirror in her handbag as thepreferred tool to inspect the $750,000 Mark I.• Developed the first compiler.• Had a clock in her office that ran counterclockwiseto illustrate that there are many ways toconceptualize solutions to problems.• Helped establish the Association for ComputingMachinery.• Was named the first Computer Sciences “Manof the Year” in 1969 by the Data ProcessingManagement Association.• Retired in 1986 as the oldest active officer in theNavy.Hopper died in her sleep on January 1, 1992, atage 86 and was buried in Arlington Cemetery withfull honors. Her advice for maintaining a youthful andcreative outlook by constantly broadening one’s ownknowledge base is good advice for anyone.Beyer not only writes about Hopper’s life but stringstogether the history of computers and details of thelives of others who were involved with the informationage into a well-researched book. His vivid writing styleand the numerous photos from the archives make pastevents come alive in the reader’s mind.For those who are interested in the early history ofcomputers and Hopper’s involvement in computing,the Archives Center of the Smithsonian Institution’sNational Museum of American History in Washington,DC, contains many items from the early days ofcomputing, including photos, academic articles, technicalnotes, manuals, and press clippings.Rhonda LunemannRhonda Lunemann is a senior technical writer with SiemensPLM Software and a senior member of STC’s Twin CitiesChapter.Conversation and Community: The SocialWeb for DocumentationAnne Gentle. 2009. Fort Collins, CO: XML Press. [ISBN 978-0-9822191-1-9.236 pages, including index. US$29.95 (softcover).]Anne Gentle’s Conversation andCommunity: The Social Web forDocumentation is a wake-up callfor technical communicatorswho are still not ready toembrace the social Web thattakes them beyond theircomfort zone of in-houseproduceduser guides andonline help to the realm ofblogs, wikis, and forums.Accustomed to a more formalwriting environment that allows for rigorous editingand complete content control, writers often shun thelax user-generated content populating the Internet.This, according to Gentle, is a big mistake. Instead,professional writers need to view this communicationshift as an opportunity to embrace a new collaborationwith their online audience. The results will be betterserved, happier users and continued relevance of theprofessional technical communicator.Gentle’s knowledge of this growing social Webis vast, and she excitedly shares what she knows. Shesuggests that blogs and wikis encourage a productivedialogue between writer and users. “Writers have moreconversation-starting tools at their disposal than atany other time in history,” she explains (p. 14). To helpnovices understand these social media tools, Gentlededicates an entire chapter to describing them. Sheexplains in some detail the terminology common inthe social Web, terms such as tagging, syndicated content,and community. In addition, she lists online communitiesVolume 57, Number 3, August 2010 l Technical Communication 349
