Da die Computer immer wichtiger in jedem Aspekt des menschlichen Lebens sind, steigt der Bedarf um entsprechend neue Konzepte in den Programmiersprachen auszudrücken. Jedoch, damit unsere Denkweise sich weiterentwicklen könnte, müssen sich auch die Programmiersprachen weiterentwickeln. Aber welche Hilfsmittel gibt es um die Programmiersprachen zu schaffen und aufzurüsten? Wie kann man Entwickler ermutigen damit sie eigene Sprachen definieren, die dem Bereich in dem sie arbeiten am besten passen? Heutzutage gibt es zwei Methoden. -

Platform Systems Vs. Step Processes—The Value of Options and the Power of Modularity by Carliss Y
© Carliss Y. Baldwin Comments welcome. Design Rules, Volume 2: How Technology Shapes Organizations Chapter 13 Platform Systems vs. Step Processes—The Value of Options and the Power of Modularity By Carliss Y. Baldwin Note to Readers: This is a draft of Chapter 13 of Design Rules, Volume 2: How Technology Shapes Organizations. It builds on prior chapters, but I believe it is possible to read this chapter on a stand-alone basis. The chapter may be cited as: Baldwin, C. Y. (2019) “Platform Systems vs. Step Processes—The Value of Options and the Power of Modularity,” HBS Working Paper (January 2019). I would be most grateful for your comments on any aspect of this chapter! Thank you in advance, Carliss. Abstract The purpose of this chapter is to contrast the value structure of platform systems (e.g. a computer) with step processes (e.g. an assembly line). I first review the basic technical architecture of computers and argue that every computer is inherently a platform for performing computations as dictated by their programs. I state and prove five propositions about platform systems, which stand in contrast to the propositions derived for step processes in Chapter 8. The propositions suggest that platform systems and step processes call for different forms of organization. Specifically, step processes reward technical integration, unified governance, risk aversion, and the use of direct authority, while platform systems reward modularity, distributed governance, risk taking, and autonomous decision-making. Despite these differences, treating platform systems and step processes as mutually exclusive architectures sets up a false dichotomy. Creating any good requires carrying out a technical recipe, i.e., performing a series of steps. -

Piore Award, 1978; IEEE Computer Society Pioneer Award, 1980; member, Information Processing Hall of Fame, Infornart, Dallas, Texas, 1985. Mauchly was born in Cincinnati, Ohio, on August 30, 1907. He attended Johns Hopkins University initially as an engineering student but later transferred into physics. He received his PhD degree in physics in 1932 and the following year became a professor of physics at Ursinus College in Collegeville, Pennsylvania. At Ursinus he was well known for his excellent and dynamic teaching, and for his research in meteorology. Because his meteorological work required extensive calculations, he began to experiment with alternatives to mechanical tabulating equipment in an effort to reduce the time required to solve meteorological equations. -

Oral History Interview with Herman Goldstine
An Interview with HERMAN GOLDSTINE OH 18 Conducted by Nancy Stern on 11 August 1980 Charles Babbage Institute The Center for the History of Information Processing University of Minnesota 1 Herman Goldstine Interview 11 August 1980 Abstract Goldstine, associate director of the Institute for Advanced Study (IAS) computer project from 1945 to 1956, discusses his role in the project. He describes the acquisition of funding from the Office of Naval Research, the hiring of staff, and his relationship with John von Neumann. Goldstine explains that von Neumann was responsible for convincing the Institute to sponsor the computer project. Goldstine praises von Neumann's contributions, among which he counts the first logical design of a computer and the concept of stored programming. Goldstine turns next to the relations between the project and one of its funders, the Atomic Energy Commission. He points out the conflict of interest of IAS director Robert Oppenheimer, who chaired the AEC General Advisory Committee, and von Neumann who sat on this committee, when other AEC officials discontinued funding for the project. Goldstine also recounts the problems that arose during the project over patent rights and their resolution. Goldstine concludes by discussing the many visitors to the project and the many computers (Whirlwind, ILLIAC, JOHNNIAC, IBM 70l) modeled after the IAS computer. 2 HERMAN GOLDSTINE INTERVIEW DATE: 11 August 1980 INTERVIEWER: Nancy Stern LOCATION: Princeton, NJ STERN: This is an interview with Herman Goldstine in his home; August 11, 1980. What I'd like to talk about, Herman, for the most part today, is your work with von Neumann at the Institute; that is, the computer project at the Institute; because we've spoken in the past about the Moore School work. -
History of ENIAC
A Short History of the Second American Revolution by Dilys Winegrad and Atsushi Akera (1) Today, the northeast corner of the old Moore School building at the University of Pennsylvania houses a bank of advanced computing workstations maintained by the professional staff of the Computing and Educational Technology Service of Penn's School of Engineering and Applied Science. There, fifty years ago, in a larger room with drab- colored walls and open rafters, stood the first general purpose electronic computer, the Electronic Numerical Integrator And Computer, or ENIAC. It spanned 150 feet in width with twenty banks of flashing lights indicating the results of its computations. ENIAC could add 5,000 numbers or do fourteen 10-digit multiplications in a second-- dead slow by present-day standards, but fast compared with the same task performed on a hand calculator. The fastest mechanical relay computers being operated experimentally at Harvard, Bell Laboratories, and elsewhere could do no more than 15 to 50 additions per second, a full two orders of magnitude slower. By showing that electronic computing circuitry could actually work, ENIAC paved the way for the modern computing industry that stands as its great legacy. ENIAC was by no means the first computer. In 1839, an Englishman Charles Babbage designed and developed the first true mechanical digital computer, which he described as a "difference engine," for solving mathematical problems including simple differential equations. He was assisted in his work by a woman mathematician, Ada Countess Lovelace, a member of the aristocracy and the daughter of Lord Byron. They worked out the mathematics of mechanical computation, which, in turn, led Babbage to design the more ambitious analytical engine.
