The history of the computing community, although small in number, is great in spirit, and is as welcoming a collection of scholars as I have ever encountered. Two of the senior members of this community have proven particu- larly supportive of me and my work. William Aspray has served as an adviser and mentor from almost the beginning of my career, and has been unfailingly generous in his time, energy, and encouragement. The late Michael Mahoney, whose wit and erudition will be sorely missed by the community, also served as a model of unselfi sh scholarship. It would be impossible to detail the many ways in which both of these scholars have informed, and continue to inform, my own thinking and scholarship. This book started as a dissertation, and owes much to the friends and advisers who guided it through its earliest incarnations. Emily Thompson, Robert Kohler, and Walter Licht served as patient readers of many, many early drafts, and without their kind and enlightened counsel this project would never have made it past its infancy. Josh Buhs, Thomas Haigh, Atsushi Akera, and the rest of my graduate school cohort listened for years to my vague musings on the eccentricities of early computer pro- grammers, and their feedback helped refi ne my thoughts and arguments. Edward Bell and the rest of the crew at E. J. Bell and Associates, by providing me with frequent opportunities to pick up consulting work, made it possible for me to fi nish graduate school without going under fi nancially. My colleagues at the University of Pennsylvania have been patient and gracious sounding boards and mentors. Ruth Schwartz Cowan, who x Acknowledgments served as the chair of the department for most of the formative years of this manuscript, allowed me time and space to balance my research and teaching. Susan Lindee has continued that tradition. Both of them have provided much support and encouragement. Janet Tighe has served as a fount of wisdom and sanity for almost a decade. John Tresch and Beth Linker have struggled alongside me in the trenches as my fellow junior faculty members. My other senior colleagues have been endlessly giving of their advice and solicitude. I appreciate all of them greatly. There are far too many archivists, librarians, and fellow historians who contributed to this project to identify them individually here. The Charles Babbage Institute, however, cannot go unmentioned. Not only does the Babbage hold the vast majority of the source material used to construct this history but also it serves as the center of gravity of the entire history of the computing community. It also provided generous funding in the form of the Tomash Fellowship in the History of Information Processing. Tom Misa, Jeff Yost, and Arthur Norberg have all served as trusted friends and advisers. Finally, like most academic book projects, this one has absorbed more than its share of my time and energy outside the offi ce. Many thanks to all of my family. My parents, Elisabeth and Stephen, made possible so many opportunities in my life. My wife, Deborah, has been a constant companion and source of loving support, and has been endlessly forgiv- ing of my need to stretch the project out with “ just one more ” revision. My three sons, Asher, Tate, and Tucker, made the process bearable by providing joy, motivation, and strength each day. 1 Introduction: Computer Revolutionaries To be a good programmer today is as much a privilege as it was to be a literate man in the sixteenth century. This privilege leads the programmer to expect rec- ognition and respect on the part of society. Unfortunately, such recognition is not always realized. — Andrei Ershov, Aesthetics and the Human Factor in Programming , 1972 The Computer People Chances are that you or someone close to you makes their living “ working with computers. ” In the decades since the 1950s, the technical spe- cialists most directly associated with the electronic digital computer— computer programmers, systems analysts, and network and database administrators — have assumed an increasingly active and visible role in the shaping of our modern information society. All but the smallest organizations now have their own information technology departments fi lled with such specialists, and in many cases they represent some of the organization ’ s most valued — or at least most highly paid — employees. In the United States alone there are more than three million professional computer experts; the total worldwide estimate is nearly thirty-fi ve million. 1 There are now more people working in computing than in all of the other fi elds of engineering and architecture combined. In recent years, “ computer people ” have become some of our wealthiest citizens, most important business leaders and philanthropists, and most recog- nized celebrities. It is likely, however, that unless you yourself are one of these com- puter people, you have at best a vague notion of what it actually means to work with computers. Even compared to other esoteric scientifi c or technical disciplines, the work of computer specialists is opaque to out- siders. Their activities are often regarded by nonpractitioners as being at 2 Chapter 1 once too diffi cult and technical to be understood by mere mortals, and too trivial and tedious to be worth the effort. The specialists themselves talk about what they do as being a mysterious blend of art and science, high tech and black magic. Many of the colloquial terms that are fre- quently used to describe these experts — “ hackers, ” “ wizards, ” “ cowboys, ” or “ gurus ” — refl ect the ambivalent fusion of wonder, awe, and suspicion with which they are generally regarded. 2 That so many of these computer specialists seem unwilling (or unable) to communicate to others what it is they do or how they do it only exacerbates the apparent impenetrabil- ity of their discipline. But while you might not know much about what it is that these com- puter specialists do, you probably can at least imagine what they look like: the stereotype of the scruffy, bearded, long-haired programmer, wearing (inappropriately) sandals and a T-shirt, has been a staple of popular culture since at least the early 1960s.

  • Women in Computing History
    Women in Computing History Denise Gfirer ACM-W0) Co-Chair EMD Consulting Scotts Valley, California 95066 USA <[email protected]> Introduction Exciting inventions, innovative technology, human interac- tion, and intriguing politics fill computing history. However, the recorded history is mainly composed of male achieve- ments and involvements, even though women have played substantial roles. This situation is not unusual. Most science fields are notorious for excluding, undervaluing, or over- looking the accomplishments of their female scientists [1, 16, 17, 22]. As J.A.N. Lee points out, it is up to the histori- ans and others to remedy this imbalance (see this issue [14]). Some steps have been taken towards this goal through pub- lishing biographies on women in technology [2, 5, 6, 8, 10, 12, 13, 18, 20, 21, 23, 24], also see this issue [7], and through honoring the pioneers with various awards such as the GHC'97 Pioneering Awards(z) (Figure 1), the WITI Hall of Fame(3), and the AWC Lovelace Award(n). A few online sites Figure 1: Computer Science Pioneer Celebration, at the Grace Hopper contain biographies of women in technology, shown in Table Celebration of Women in Computing '97.

Abstract Software is developed in increasingly dynamic environments. Organizations need the capability to deal with uncertainty and to react to unexpected changes in require- ments and technologies. Agile methods already improve the flexibility towards changes and with the emergence of continuous delivery, regular feedback loops have become possible. The abilities to maintain high code quality through reviews, to regularly re- lease software, and to collect and prioritize user feedback, are necessary for con- tinuous software engineering. However, there exists no uniform process model that handles the increasing number of reviews, releases and feedback reports. In this dissertation, we describe Rugby, a process model for continuous software en- gineering that is based on a meta model, which treats development activities as parallel workflows and which allows tailoring, customization and extension. Rugby includes a change model and treats changes as events that activate workflows. It integrates re- view management, release management, and feedback management as workflows. As a consequence, Rugby handles the increasing number of reviews, releases and feedback and at the same time decreases their size and effort.

What interests us is how past futures and therefore history were stabilized. The development, operation, and implementation of machines and programs gave rise to a historicity of the field of computing. Whenever actors have been grouped into communities – for example, into industrial and academic developer communities – new orderings have been constructed historically. Such orderings depend on the ability to refer to archival and published documents and to develop new narratives based on them. Professional historians are particularly at home in these waters – and nevertheless can disappear into the whirlpool of digital prehistory. Toward the end of the 1980s, the first critical review of the literature on the history of computers thus offered several programmatic suggestions. It is one of the peculiar coincidences of history that the future should rear its head again just when the history of computers was flourishing as a result of massive methodological and conceptual input.

  • Turing's Influence on Programming — Book Extract from “The Dawn of Software Engineering: from Turing to Dijkstra”
    Turing's Influence on Programming | Book extract from \The Dawn of Software Engineering: from Turing to Dijkstra" Edgar G. Daylight∗ Eindhoven University of Technology, The Netherlands [email protected] Abstract Turing's involvement with computer building was popularized in the 1970s and later. Most notable are the books by Brian Randell (1973), Andrew Hodges (1983), and Martin Davis (2000). A central question is whether John von Neumann was influenced by Turing's 1936 paper when he helped build the EDVAC machine, even though he never cited Turing's work. This question remains unsettled up till this day. As remarked by Charles Petzold, one standard history barely mentions Turing, while the other, written by a logician, makes Turing a key player. Contrast these observations then with the fact that Turing's 1936 paper was cited and heavily discussed in 1959 among computer programmers. In 1966, the first Turing award was given to a programmer, not a computer builder, as were several subsequent Turing awards. An historical investigation of Turing's influence on computing, presented here, shows that Turing's 1936 notion of universality became increasingly relevant among programmers during the 1950s. The central thesis of this paper states that Turing's in- fluence was felt more in programming after his death than in computer building during the 1940s. 1 Introduction Many people today are led to believe that Turing is the father of the computer, the father of our digital society, as also the following praise for Martin Davis's bestseller The Universal Computer: The Road from Leibniz to Turing1 suggests: At last, a book about the origin of the computer that goes to the heart of the story: the human struggle for logic and truth.

    The Strange Birth and Long Life of Unix - IEEE Spectrum Page 1 of 6 COMPUTING / SOFTWARE FEATURE The Strange Birth and Long Life of Unix The classic operating system turns 40, and its progeny abound By WARREN TOOMEY / DECEMBER 2011 They say that when one door closes on you, another opens. People generally offer this bit of wisdom just to lend some solace after a misfortune. But sometimes it's actually true. It certainly was for Ken Thompson and the late Dennis Ritchie, two of the greats of 20th-century information technology, when they created the Unix operating system, now considered one of the most inspiring and influential pieces of software ever written. A door had slammed shut for Thompson and Ritchie in March of 1969, when their employer, the American Telephone & Telegraph Co., withdrew from a collaborative project with the Photo: Alcatel-Lucent Massachusetts Institute of KEY FIGURES: Ken Thompson [seated] types as Dennis Ritchie looks on in 1972, shortly Technology and General Electric after they and their Bell Labs colleagues invented Unix. to create an interactive time- sharing system called Multics, which stood for "Multiplexed Information and Computing Service." Time-sharing, a technique that lets multiple people use a single computer simultaneously, had been invented only a decade earlier. Multics was to combine time-sharing with other technological advances of the era, allowing users to phone a computer from remote terminals and then read e -mail, edit documents, run calculations, and so forth. It was to be a great leap forward from the way computers were mostly being used, with people tediously preparing and submitting batch jobs on punch cards to be run one by one.

  • MAKING DATA MODELS READABLE David C
    MAKING DATA MODELS READABLE David C. Hay Essential Strategies, Inc. “Confusion and clutter are failures of [drawing] design, not attributes of information. And so the point is to find design strategies that reveal detail and complexity ¾ rather than to fault the data for an excess of complication. Or, worse, to fault viewers for a lack of understanding.” ¾ Edward R. Tufte1 Entity/relationship models (or simply “data models”) are powerful tools for analyzing and representing the structure of an organization. Properly used, they can reveal subtle relationships between elements of a business. They can also form the basis for robust and reliable data base design. Data models have gotten a bad reputation in recent years, however, as many people have found them to be more trouble to produce and less beneficial than promised. Discouraged, people have gone on to other approaches to developing systems ¾ often abandoning modeling altogether, in favor of simply starting with system design. Requirements analysis remains important, however, if systems are ultimately to do something useful for the company. And modeling ¾ especially data modeling ¾ is an essential component of requirements analysis. It is important, therefore, to try to understand why data models have been getting such a “bad rap”. Your author believes, along with Tufte, that the fault lies in the way most people design the models, not in the underlying complexity of what is being represented. An entity/relationship model has two primary objectives: First it represents the analyst’s public understanding of an enterprise, so that the ultimate consumer of a prospective computer system can be sure that the analyst got it right.
