Book Description
At the dawn of the computer age, an elite development team at IBM built the most influential computer programming language in history: FORTRAN. Abstracting Away the Machine tells the epic story of how they did it--and what happened next. Over the past six decades, programming languages like ALGOL, BASIC, C/C++, COBOL, Java, LISP, LOGO, Pascal, PL/I, Python, Visual Basic, and many others opened up the field of computer science, and of computer programming in general, to the masses. But all of these high-level languages (HLLs)--computer languages that automate, hide, or otherwise abstract away the underlying operations of the machine--owe a huge debt of gratitude to FORTRAN (FORmula TRANslation), the first HLL to achieve widespread adoption. Many programming practices that we take for granted now came about as a result of FORTRAN. Created over a three-year period at IBM by a development team led by a brilliant but wayward mathematician named John W. Backus, FORTRAN was implemented initially on the IBM 704 mainframe computer in the mid-1950s, with dialects of the language quickly spreading thereafter to other platforms. FORTRAN's powerful compiler, which translated human-readable code into code a computer could understand, produced incredibly clean and optimized standalone executable programs, all of which could be run independently of the compiler, setting the standard for decades to come--and overcoming the doubts of many skeptics along the way, who thought the FORTRAN project would never succeed. In the 1960s the language was standardized, with machine-dependent commands excised, and many platform-independent implementations followed. With the language now portable, able to run on any computer (at least in theory), FORTRAN, almost by accident, secured a stranglehold in the fields of science and engineering. The language also came to dominate in the supercomputing industry. But FORTRAN, a blue-collar workhorse more concerned with results than with style, was a victim of its own success--the language sowed the seeds of its own demise. New high-level languages sprouted up, stealing the good bits from FORTRAN while simultaneously defining themselves in opposition to it. FORTRAN had become the foil. As these new languages pierced the cutting edge of the programming landscape, they redefined computing paradigms (e.g., with structured programming, object-oriented programming, and the like), and FORTRAN--though eventually (and repeatedly) modernized and formally renamed Fortran--struggled to keep up through multiple standardization efforts, finally ceding significant ground to its successors as it slowly withdrew from the spotlight. To add insult to injury, even John Backus eventually turned against his creation. This is not a book on how to program in FORTRAN, nor is it a technical manual. Rather, the focus in Abstracting Away the Machine, which chronicles the complete history and development of the FORTRAN programming language, is set squarely on telling three interlocking stories: (1) How an elite group of computing trailblazers built FORTRAN, (2) Why the conditions at the time were ripe for them to succeed, and (3) What happened after they did. Tracing the long arc of FORTRAN's development and maturation is integral to understanding not only the history of programming but also the state of computer science today. The birth of FORTRAN planted a seed that led to the full flowering of high-level languages, since FORTRAN overcame initial skepticism by demonstrating to the world that a well-made HLL really could abstract away the machine.

Book Description
"Endless Loop" chronicles the complete history of the BASIC programming language--from its humble beginnings at Dartmouth College, to its widespread adoption and dominance in education, to its decline and subsequent modern rebirth.In the early morning hours of May 1, 1964, Dartmouth College birthed fraternal twins: BASIC, the Beginner's All-purpose Symbolic Instruction Code programming language, and, simultaneously, the Dartmouth Time-Sharing System (DTSS). It hadn't been an easy birth, and the gestation period was likewise difficult. BASIC was primarily the idea of one man, mathematics professor John Kemeny, a brilliant Hungarian mathematician who had once been an assistant to Albert Einstein, while the DTSS satisfied the vision of another, mathematics and statistics professor Thomas Kurtz, who had brought a democratizing spirit to Dartmouth's campus in the form of free computing for all.BASIC and DTSS caught on at Dartmouth quickly, with a vast majority of undergraduates (and faculty) making use of the computer system via teletypewriters only several years after its inception. But by the early 1970s, with the personal computer revolution fast approaching, Kemeny and Kurtz began to lose control over BASIC as it achieved widespread popularity outside of Dartmouth. The language was being adapted to run on a wide variety of computers, some much too short of memory to contain the full set of Dartmouth BASIC features. Most notably, Microsoft built its business on the back of ROM-based BASIC interpreters for a variety of microcomputers. Although the language was ubiquitous in schools by the early 1980s, it came under attack by such notables as computer scientist Edsger W. Dijkstra for its lack of structure as well as by Kemeny and Kurtz themselves, who viewed non-Dartmouth "Street BASIC" as blasphemous and saw it as their mission to right the ship through language standardization and the release of True BASIC. But by then it was too late: the era of BASIC's global dominance was over.In "Endless Loop," author Mark Jones Lorenzo documents the history and development of Dartmouth BASIC, True BASIC, Tiny BASIC, Microsoft BASIC--including Altair BASIC, Applesoft BASIC, Color BASIC, Commodore BASIC, TRS-80 Level II BASIC, TI BASIC, IBM BASICA/GW-BASIC, QuickBASIC/QBASIC, Visual Basic, and Small Basic--as well as 9845 BASIC, Atari BASIC, BBC BASIC, CBASIC, Locomotive BASIC, MacBASIC, QB64, Simons' BASIC, Sinclair BASIC, SuperBASIC, and Turbo Basic/PowerBASIC, among a number of other implementations.The ascendance of BASIC paralleled the emergence of the personal computer, so the story of BASIC is first and foremost a story--actually, many interlocking stories--about computers. But it is also a tale of talented people who built a language out of a set of primal ingredients: sweat, creativity, rivalry, jealousy, cooperation, and plain hard work, and then set the language loose in a world filled with unintended consequences. How those unintended consequences played out, leading to the demise of the most popular computer language the world has ever known, is the focus of "Endless Loop."

The First Computers

The First Computers PDF Author: Raul Rojas
Publisher: MIT Press
ISBN: 9780262681377
Category : Science
Languages : en
Pages : 476

Book Description
This history of computing focuses not on chronology (what came first and who deserves credit for it) but on the actual architectures of the first machines that made electronic computing a practical reality. The book covers computers built in the United States, Germany, England, and Japan. It makes clear that similar concepts were often pursued simultaneously and that the early researchers explored many architectures beyond the von Neumann architecture that eventually became canonical. The contributors include not only historians but also engineers and computer pioneers. An introductory chapter describes the elements of computer architecture and explains why "being first" is even less interesting for computers than for other areas of technology. The essays contain a remarkable amount of new material, even on well-known machines, and several describe reconstructions of the historic machines. These investigations are of more than simply historical interest, for architectures designed to solve specific problems in the past may suggest new approaches to similar problems in today's machines.

This book is for anyone who uses Fortran, from the novice learner to the advanced expert. It describes best practices for programmers, scientists, engineers, computer scientists and researchers who want to apply good style and incorporate rigorous usage in their own Fortran code or to establish guidelines for a team project. The presentation concentrates primarily on the characteristics of Fortran 2003, while also describing methods in Fortran 90/95 and valuable new features in Fortran 2008. The authors draw on more than a half century of experience writing production Fortran code to present clear succinct guidelines on formatting, naming, documenting, programming and packaging conventions and various programming paradigms such as parallel processing (including OpenMP, MPI and coarrays), OOP, generic programming and C language interoperability.

Semantics Engineering with PLT Redex

Semantics Engineering with PLT Redex PDF Author: Matthias Felleisen
Publisher: MIT Press
ISBN: 0262062755
Category : Computers
Languages : en
Pages : 515

Book Description
The first comprehensive presentation of reduction semantics in one volume, and the first tool set for such forms of semantics. This text is the first comprehensive presentation of reduction semantics in one volume; it also introduces the first reliable and easy-to-use tool set for such forms of semantics. Software engineers have long known that automatic tool support is critical for rapid prototyping and modeling, and this book is addressed to the working semantics engineer (graduate student or professional language designer). The book comes with a prototyping tool suite to develop, explore, test, debug, and publish semantic models of programming languages. With PLT Redex, semanticists can formulate models as grammars and reduction models on their computers with the ease of paper and pencil. The text first presents a framework for the formulation of language models, focusing on equational calculi and abstract machines, then introduces PLT Redex, a suite of software tools for expressing these models as PLT Redex models. Finally, experts describe a range of models formulated in Redex. PLT Redex comes with the PLT Scheme implementation, available free at http://www.plt-scheme.org/. Readers can download the software and experiment with Redex as they work their way through the book.

How to Design Programs, second edition

How to Design Programs, second edition PDF Author: Matthias Felleisen
Publisher: MIT Press
ISBN: 0262344122
Category : Computers
Languages : en
Pages : 793

Book Description
A completely revised edition, offering new design recipes for interactive programs and support for images as plain values, testing, event-driven programming, and even distributed programming. This introduction to programming places computer science at the core of a liberal arts education. Unlike other introductory books, it focuses on the program design process, presenting program design guidelines that show the reader how to analyze a problem statement, how to formulate concise goals, how to make up examples, how to develop an outline of the solution, how to finish the program, and how to test it. Because learning to design programs is about the study of principles and the acquisition of transferable skills, the text does not use an off-the-shelf industrial language but presents a tailor-made teaching language. For the same reason, it offers DrRacket, a programming environment for novices that supports playful, feedback-oriented learning. The environment grows with readers as they master the material in the book until it supports a full-fledged language for the whole spectrum of programming tasks. This second edition has been completely revised. While the book continues to teach a systematic approach to program design, the second edition introduces different design recipes for interactive programs with graphical interfaces and batch programs. It also enriches its design recipes for functions with numerous new hints. Finally, the teaching languages and their IDE now come with support for images as plain values, testing, event-driven programming, and even distributed programming.
