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. -

Towards Gradual Typing for Generics
Towards Gradual Typing for Generics Lintaro Ina and Atsushi Igarashi Graduate School of Informatics, Kyoto University {ina,igarashi}@kuis.kyoto-u.ac.jp Abstract. Gradual typing, proposed by Siek and Taha, is a framework to combine the benefits of static and dynamic typing. Under gradual typing, some parts of the program are type-checked at compile time, and the other parts are type-checked at run time. The main advantage of gradual typing is that a programmer can write a program rapidly without static type annotations in the beginning of development, then add type annotations as the development progresses and end up with a fully statically typed program; and all these development steps are carried out in a single language. This paper reports work in progress on the introduction of gradual typing into class-based object-oriented programming languages with generics. In previous work, we have developed a gradual typing system for Feather- weight Java and proved that statically typed parts do not go wrong. After reviewing the previous work, we discuss issues raised when generics are introduced, and sketch a formalization of our solutions. 1 Introduction Siek and Taha have coined the term “gradual typing” [1] for a linguistic sup- port of the evolution from dynamically typed code, which is suitable for rapid prototyping, to fully statically typed code, which enjoys type safety properties, in a single programming language. The main technical challenge is to ensure some safety property even for partially typed programs, in which some part is statically typed and the rest is dynamically typed. The framework of gradual typing consists of two languages: the surface lan- guage in which programmers write programs and the intermediate language into which the surface language translates. -
Type Feedback for Bytecode Interpreters Position Paper ICOOOLPS 2007
Type Feedback for Bytecode Interpreters Position Paper ICOOOLPS 2007 Michael Haupt1, Robert Hirschfeld1, and Marcus Denker2 1 Software Architecture Group Hasso-Plattner-Institut University of Potsdam, Germany 2 Software Composition Group Institute of Computer Science and Applied Mathematics University of Berne, Switzerland michael.haupt,hirschfeld @hpi.uni-potsdam.de, [email protected] { } Abstract. This position paper proposes the exploitation of type feed- back mechanisms, or more precisely, polymorphic inline caches, for purely interpreting implementations of object-oriented programming languages. Using Squeak’s virtual machine as an example, polymorphic inline caches are discussed as an alternative to global caching. An implementation proposal for polymorphic inline caches in the Squeak virtual machine is presented, and possible future applications for online optimization are outlined. 1 Introduction Bytecode interpreters are small in size and comparatively easy to implement, but generally execute programs much less efficiently than just-in-time (JIT) compilers. Techniques like threaded interpretation [9, 11, 2] focus on speeding up bytecode interpretation itself, and caching [4, 5, 1] improves the performance of message sends—the most common operation in object-oriented software [7]. It is interesting to observe that, while threading mechanisms are used natu- rally to a varying degree in bytecode interpreter implementations, such systems usually employ only global caching to speed up dynamic method dispatch. A global cache is clearly beneficial with respect to overall performance. Still, it does not provide optimal support for polymorphic message send sites, and it does not allow for exploiting type information (we provide details on these issues in the following section). In our opinion, the employment of polymorphic inline caches (PICs) [5] instead can provide means for achieving significant speedups in bytecode interpreters while exhibiting only a moderate increase in memory footprint and implementation complexity. -
A Tour of the Squeak Object Engine
A Tour of the Squeak Object Engine A Tour of the Squeak Object Engine Tim Rowledge, [email protected] Introduction This chapter is intended to explain some basics of how a Virtual Machine (VM) works, why a VM is useful, what it does for the Squeak programmer and user, and how the Squeak VM might develop in the future. What is a Virtual Machine and why do we need one? A Virtual Machine provides us with a pretense of being a machine other than the actual hardware in use. Using one allows systems that behave differently than the host hardware to run as if on hardware designed for them. The term Object Engine is less commonly used but is a useful concept that includes the lowest system areas of the langauge environment running on the VM. Since there is often some flux in the definition of which components are within the actual VM and which are part of the supported environment, Object Engine is useful as a more inclusive term. The term Virtual Machine is used in several ways. When IBM refer to VM/CMS they are referring to a way of making a mainframe behave as if it is many machines, so that programs can assume they have total control even though they do not. Intel provide a somewhat similar facility in the x86 architecture(?), referred to as Virtual Mode. This sort of VM is a complete hardware simulation, often supported at the lowest level by the hardware. Another sort of VM is the emulator - SoftWindows for the Mac, Acorn's !PC, Linux's WINE are good examples - where another machine and/or OS is simulated to allow a Mac user to run Windows programs, an Acorn RiscPC or a Linux machine to run Windows98 programs and so on. -
Research Purpose Operating Systems – a Wide Survey
GESJ: Computer Science and Telecommunications 2010|No.3(26) ISSN 1512-1232 RESEARCH PURPOSE OPERATING SYSTEMS – A WIDE SURVEY Pinaki Chakraborty School of Computer and Systems Sciences, Jawaharlal Nehru University, New Delhi – 110067, India. E-mail: [email protected] Abstract Operating systems constitute a class of vital software. A plethora of operating systems, of different types and developed by different manufacturers over the years, are available now. This paper concentrates on research purpose operating systems because many of them have high technological significance and they have been vividly documented in the research literature. Thirty-four academic and research purpose operating systems have been briefly reviewed in this paper. It was observed that the microkernel based architecture is being used widely to design research purpose operating systems. It was also noticed that object oriented operating systems are emerging as a promising option. Hence, the paper concludes by suggesting a study of the scope of microkernel based object oriented operating systems. Keywords: Operating system, research purpose operating system, object oriented operating system, microkernel 1. Introduction An operating system is a software that manages all the resources of a computer, both hardware and software, and provides an environment in which a user can execute programs in a convenient and efficient manner [1]. However, the principles and concepts used in the operating systems were not standardized in a day. In fact, operating systems have been evolving through the years [2]. There were no operating systems in the early computers. In those systems, every program required full hardware specification to execute correctly and perform each trivial task, and its own drivers for peripheral devices like card readers and line printers.
