  • Retrocomputing As Preservation and Remix
    Retrocomputing as Preservation and Remix Yuri Takhteyev Quinn DuPont University of Toronto University of Toronto [email protected] [email protected] Abstract This paper looks at the world of retrocomputing, a constellation of largely non-professional practices involving old computing technology. Retrocomputing includes many activities that can be seen as constituting “preservation.” At the same time, it is often transformative, producing assemblages that “remix” fragments from the past with newer elements or joining together historic components that were never combined before. While such “remix” may seem to undermine preservation, it allows for fragments of computing history to be reintegrated into a living, ongoing practice, contributing to preservation in a broader sense. The seemingly unorganized nature of retrocomputing assemblages also provides space for alternative “situated knowledges” and histories of computing, which can sometimes be quite sophisticated. Recognizing such alternative epistemologies paves the way for alternative approaches to preservation. Keywords: retrocomputing, software preservation, remix Recovering #popsource In late March of 2012 Jordan Mechner received a shipment from his father, a box full of old floppies. Among them was a 3.5 inch disk labelled: “Prince of Persia / Source Code (Apple) / ©1989 Jordan Mechner (Original).” Mechner’s announcement of this find on his blog the next day took the world of nerds by storm.1 Prince of Persia, a game that Mechner single-handedly developed in the late 1980s, revolutionized computer games when it came out due to its surprisingly realistic representation of human movement. After being ported to DOS and Apple’s Mac OS in the early 1990s the game sold 2 million copies (Pham, 2001).

Käyttöjärjestelmissä Applen pahin kilpailija Microsoft on saavuttanut markkina-asemansa lisensoimalla käyttöjärjestelmänsä kenelle tahansa, Apple sen sijaan on sitonut käyttöjärjestelmänsä tiukasti itse valmistamiinsa tieto- koneisiin. Muun muassa tämän takia Applen markkinaosuus henkilökohtaisista tie- tokoneista on pysynyt matalana viimeiset 20 vuotta. Pienestä markkinaosuudestaan huolimatta sen tuotteet ovat aina herättäneet huomiota. Apple on käyttöjärjestel- missään esitellyt monia mullistavia teknologioita. Tämän esitelmän tarkoitus on esi- tellä Applen käyttöjärjestelmiä ja niitä varten kehitettyjen tietokoneiden kehitystä, historiaa ja teknisiä ominaisuuksia.

  • An Introduction to ESS + Xemacs for Windows Users of R
    An Introduction to ESS + XEmacs for Windows Users of R John Fox∗ McMaster University Revised: 23 January 2005 1WhyUseESS+XEmacs? Emacs is a powerful and widely used programmer’s editor. One of the principal attractions of Emacs is its programmability: Emacs can be adapted to provide customized support for program- ming languages, including such features as delimiter (e.g., parenthesis) matching, syntax highlight- ing, debugging, and version control. The ESS (“Emacs Speaks Statistics”) package provides such customization for several common statistical computing packages and programming environments, including the S family of languages (R and various versions of S-PLUS), SAS, and Stata, among others. The current document introduces the use of ESS with R running under Microsoft Windows. For some Unix/Linux users, Emacs is more a way of life than an editor: It is possible to do almost everything from within Emacs, including, of course, programming, but also writing documents in mark-up languages such as HTML and LATEX; reading and writing email; interacting with the Unix shell; web browsing; and so on. I expect that this kind of generalized use of Emacs will not be attractive to most Windows users, who will prefer to use familiar, and specialized, tools for most of these tasks. There are several versions of the Emacs editor, the two most common of which are GNU Emacs, a product of the Free Software Foundation, and XEmacs, an offshoot of GNU Emacs. Both of these implementations are free and are available for most computing platforms, including Windows. In my opinion, based only on limited experience, XEmacs offers certain advantages to Windows users, such as easier installation, and so I will explain the use of ESS under this version of the Emacs editor.1 As I am writing this, there are several Windows programming editors that have been customized for use with R.

  • Survey and Benchmarking of Machine Learning Accelerators
    1 Survey and Benchmarking of Machine Learning Accelerators Albert Reuther, Peter Michaleas, Michael Jones, Vijay Gadepally, Siddharth Samsi, and Jeremy Kepner MIT Lincoln Laboratory Supercomputing Center Lexington, MA, USA freuther,pmichaleas,michael.jones,vijayg,sid,[email protected] Abstract—Advances in multicore processors and accelerators components play a major role in the success or failure of an have opened the flood gates to greater exploration and application AI system. of machine learning techniques to a variety of applications. These advances, along with breakdowns of several trends including Moore’s Law, have prompted an explosion of processors and accelerators that promise even greater computational and ma- chine learning capabilities. These processors and accelerators are coming in many forms, from CPUs and GPUs to ASICs, FPGAs, and dataflow accelerators. This paper surveys the current state of these processors and accelerators that have been publicly announced with performance and power consumption numbers. The performance and power values are plotted on a scatter graph and a number of dimensions and observations from the trends on this plot are discussed and analyzed. For instance, there are interesting trends in the plot regarding power consumption, numerical precision, and inference versus training. We then select and benchmark two commercially- available low size, weight, and power (SWaP) accelerators as these processors are the most interesting for embedded and Fig. 1. Canonical AI architecture consists of sensors, data conditioning, mobile machine learning inference applications that are most algorithms, modern computing, robust AI, human-machine teaming, and users (missions). Each step is critical in developing end-to-end AI applications and applicable to the DoD and other SWaP constrained users.

  • Autodesk and Autocad
    Chapter 8 Autodesk and AutoCAD Autodesk as a company, has gone through several distinct phases of life. There were the “Early Years” which covers the time from when Autodesk was founded as a loose programmer-centric collaborative in early 1982 to the company’s initial public offering in 1985, the “Adolescent Years” during which the company grew rapidly but seemed to do so without any clear direction and the “Mature Years.” The beginning of the latter phase began when Carol Bartz became president and CEO in 1992 and continues to the current time. Even under Bartz, there were several well defined periods of growth as well as some fairly stagnant years.1 Mike Riddle gets hooked on computers Mike Riddle was born in California with computers in his veins. In junior high school, he built his first computer out of relays. It didn’t work very well, but it convinced him that computers were going to be an important part of his life. After attending Arizona State University, Riddle went to work for a steel fabricator where he had his first exposure to CAD. The company had a $250,000 Computervision system that, although capable of 3D work, was used strictly for 2D drafting. The company was engaged in doing steel detailing for the Palo Verde nuclear power plant in Arizona. Riddle felt that anything they were doing on this project with the Computervision system could be done on a microcomputer-based system. About the same time Riddle began working at a local Computerland store where they provided him with free computer time to do with as he wanted.
