  • The Future: the Story of Squeak, a Practical Smalltalk Written in Itself
    Back to the future: the story of Squeak, a practical Smalltalk written in itself Dan Ingalls, Ted Kaehler, John Maloney, Scott Wallace, and Alan Kay [Also published in OOPSLA ’97: Proc. of the 12th ACM SIGPLAN Conference on Object-oriented Programming, 1997, pp. 318-326.] VPRI Technical Report TR-1997-001 Viewpoints Research Institute, 1209 Grand Central Avenue, Glendale, CA 91201 t: (818) 332-3001 f: (818) 244-9761 Back to the Future The Story of Squeak, A Practical Smalltalk Written in Itself by Dan Ingalls Ted Kaehler John Maloney Scott Wallace Alan Kay at Apple Computer while doing this work, now at Walt Disney Imagineering 1401 Flower Street P.O. Box 25020 Glendale, CA 91221 [email protected] Abstract Squeak is an open, highly-portable Smalltalk implementation whose virtual machine is written entirely in Smalltalk, making it easy to debug, analyze, and change. To achieve practical performance, a translator produces an equivalent C program whose performance is comparable to commercial Smalltalks. Other noteworthy aspects of Squeak include: a compact object format that typically requires only a single word of overhead per object; a simple yet efficient incremental garbage collector for 32-bit direct pointers; efficient bulk- mutation of objects; extensions of BitBlt to handle color of any depth and anti-aliased image rotation and scaling; and real-time sound and music synthesis written entirely in Smalltalk. Overview Squeak is a modern implementation of Smalltalk-80 that is available for free via the Internet, at http://www.research.apple.com/research/proj/learning_concepts/squeak/ and other sites. It includes platform-independent support for color, sound, and image processing.

DON’T PANIC ABSTRACT During the past decade, software developers widely adopted JVM and CLI as multi-language virtual machines (VMs). At the same time, the multicore revolution burdened developers with increasing complexity. Language im- plementers devised a wide range of concurrent and parallel programming concepts to address this complexity but struggle to build these concepts on top of common multi-language VMs. Missing support in these VMs leads to tradeoffs between implementation simplicity, correctly implemented lan- guage semantics, and performance guarantees. Departing from the traditional distinction between concurrency and paral- lelism, this dissertation finds that parallel programming concepts benefit from performance-related VM support, while concurrent programming concepts benefit from VM support that guarantees correct semantics in the presence of reflection, mutable state, and interaction with other languages and libraries.

The NoteTaker2 is a portable computer of considerable power useful for a wide range of computational and simulation­ oriented functions. XEROX PALO ALTO RESEARCH CENTER 3333 Coyote Hill Road / Palo Alto / California 94304 This document is for Xerox internal use only DRAFT· DRAFT· DRAFT· DRAFT NoteTaker2 System Manual - DRAFT· DRAFT ~ September 30, 1979 5:39 PM 2 PREFACE NoteTaker2 is a very powerful portable computer intended for a wide variety of applications. Its intended users are "children of all ages": five-year-olds and high school students, as well as writers, researchers, artists, managers, and engineers. NoteTaker2 offers the capability of a general-purpose minicomputer, and allows it to be used without even plugging it into an AC power outlet. This manual describes the hardware components of the system in three levels of detail. The introduction summarizes the main features of the NoteTaker2 hardware. Section 2 gives an overview of the architecture. Section 3 offers the detail required to program the system and to interface other devices to it. NoteTaker2 has its roots in the long-time desire of the Learning Research Group at the Xerox Palo Alto Research Center (Xerox PARe) to have a portable system on which to experiment with its ideas concerning personal computers. The architecture of the machine was defined by Douglas Fairbairn of the LSI Systems Area at PARC in conjunction with LRG.

  • On the Revival of Dynamic Languages
    On the Revival of Dynamic Languages Oscar Nierstrasz, Alexandre Bergel, Marcus Denker, St´ephane Ducasse, Markus G¨alli, and Roel Wuyts Software Composition Group, University of Bern www.iam.unibe.ch/∼scg Abstract. The programming languages of today are stuck in a deep rut that has developed over the past 50 years. Although we are faced with new challenges posed by enormous advances in hardware and internet technology, we continue to struggle with old-fashioned languages based on rigid, static, closed-world file-based views of programming. We argue the need for a new class of dynamic languages that support a view of pro- gramming as constant evolution of living and open software models. Such languages would require features such as dynamic first-class namespaces, explicit meta-models, optional, pluggable type systems, and incremental compilation of running software systems. 1 Introduction It is no exaggeration to say that mainstream programming languages of today are inherently static. That is to say, these languages tolerate change at compile time, but precious little at run-time. To state the case more strongly, most languages assume a closed world view: specifically, they assume that the world is consistent, and it will not change. That this assumption is patently false is obvious to anyone who has experi- enced the development of real, large software systems. Nevertheless, it is a fact that virtually no programming language today provides specific language mech- anisms to help developers cope with the fact that the systems they work on will, inevitably change [LB85]. As concrete examples, we can observe that it is hard to: – modify a running system, – make changes that impact the whole system, – reason about consequences of change, – introduce run-time reflection on-demand, – keep code, documentation and tests synchronized.

  • Chapter 3 – Design Patterns: Model-View- Controller
    SOFTWARE ARCHITECTURES Chapter 3 – Design Patterns: Model-View- Controller Martin Mugisha Brief History Smalltalk programmers developed the concept of Model-View-Controllers, like most other software engineering concepts. These programmers were gathered at the Learning Research Group (LRG) of Xerox PARC based in Palo Alto, California. This group included Alan Kay, Dan Ingalls and Red Kaehler among others. C language which was developed at Bell Labs was already out there and thus they were a few design standards in place[ 1] . The arrival of Smalltalk would however change all these standards and set the future tone for programming. This language is where the concept of Model-View- Controller first emerged. However, Ted Kaehler is the one most credited for this design pattern. He had a paper in 1978 titled ‘A note on DynaBook requirements’. The first name however for it was not MVC but ‘Thing-Model-View-Set’. The aim of the MVC pattern was to mediate the way the user could interact with the software[ 1] . This pattern has been greatly accredited with the later development of modern Graphical User Interfaces(GUI). Without Kaehler, and his MVC, we would have still been using terminal to input our commands. Introduction Model-View-Controller is an architectural pattern that is used for implementing user interfaces. Software is divided into three inter connected parts. These are the Model, View, and Controller. These inter connection is aimed to separate internal representation of information from the way it is presented to accepted users[ 2] . fig 1 SOFTWARE ARCHITECTURES As shown in fig 1, the MVC has three components that interact to show us our unique information.

  • Commemorative Booklet for the Thirty-Fifth Asilomar Microcomputer Workshop April 15-17, 2009 Programs from the 1975-2009 Worksho
    35 Commemorative Booklet for the Thirty-Fifth Asilomar Microcomputer Workshop April 15-17, 2009 Programs from the 1975-2009 Workshops This file available at www.amw.org AMW: 3dh Workshop Prologue - Ted Laliotis The Asilomar Microcomputer Workshop (AMW) has played a very important role during its 30 years ofexistence. Perhaps, that is why it continues to be well attended. The workshop was founded in 1975 as an IEEE technical workshop sponsored by the Western Area Committee ofthe IEEE Computer Society. The intentional lack of written proceedings and the exclusion of general press representatives was perhaps the most distinctive characteristic of AMW that made it so special and successful. This encouraged the scientists and engineers who were at the cutting edge ofthe technology, the movers and shakers that shaped Silicon Valley, the designers of the next generation microprocessors, to discuss and debate freely the various issues facing microprocessors. In fact, many features, or lack of, were born during the discussions and debates at AMW. We often referred to AMW and its attendees as the bowels of Silicon Valley, even though attendees came from all over the country, and the world. Another characteristic that made AMW special was the "required" participation and contribution by all attendees. Every applicant to attend AMW had to convince the committee that he had something to contribute by speaking during one of the sessions or during the open mike session. In the event that someone slipped through and was there only to listen, that person was not invited back the following year. The decades ofthe 70's and 80's were probably the defining decades for the amazing explosion of microcomputers.

  • Making Applications in Ksworld
    Making Applications in KSWorld Yoshiki Ohshima, Aran Lunzer, Bert Freudenberg Ted Kaehler VPRI Memo M-2013-003 Viewpoints Research Institute, 1209 Grand Central Avenue, Glendale, CA 91201 t: (818) 332-3001 f: (818) 244-9761 Making Applications in KSWorld Yoshiki Ohshima Aran Lunzer Bert Freudenberg Ted Kaehler Viewpoints Research Institute [email protected], [email protected], [email protected], [email protected] Abstract We report on our experiences in creating a GUI framework called KSWorld, which supports an interactive and declara- tive manner of application writing. The framework embod- ies direct manipulation, a high degree of loose coupling, and time-aware execution derived from Functional Reactive Pro- gramming (FRP). We also describe how a universal docu- ment editor was developed in this framework. The fields, or slots, of graphical widgets in KSWorld are reactive variables. Definitions of such variables can be added or modified in a localized manner, allowing on-the-fly cus- tomization of the visual and behavioral aspects of widgets and entire applications. Thus the KSWorld environment sup- ports highly exploratory application building: a user con- structs the appearance interactively with direct manipula- tion, then attaches and refines reactive-variable definitions to achieve the desired overall behavior. We also show that the system scales up sufficiently to sup- port a universal document editor. About 10,000 lines of code were needed to build the framework, the FRP evaluator, the document model and the editor, including the implementa- tion of the special language created for KSWorld.
