Welcome to ECOOP 2008 in Paphos! ECOOP 2008‘s Organizing Committee is pleased to welcome you to the lovely city of Paphos. Since it was first held in Paris in 1987, ECOOP travels for the first time to the sunny island of Cyprus. As it is traditional for the ECOOP event, this year’s “ECOOP week” fea- tures a number of workshops, tutorials, and other events, all of them complementing the main technical program. From the beginning, ECOOP has been the premier forum for discussing and advancing a broad range of topics woven together by the common thread of object technology. It offers a well-integrated collage of events, including outstanding invited speakers, carefully refereed technical pa- pers, topic-focused workshops and late-breaking demonstrations. The main reason for ECOOP‘s ongoing success is its excellent technical program, put together each year from a large number of high-quality sub- Welcome Message Message Welcome missions. This year‘s Program Chair is Jan Vitek, with whom it has been a great pleasure to cooperate. We are delighted to announce three outstanding keynote talks. The con- ference keynote will be given by Rachid Guerraoui. The other keynote talks will be given by Akinori Yonezawa and Wolfgang De Meuter, the 2008 winners of the AITO Dahl-Nygaard Awards. These prizes, named after Ole-Johan Dahl and Kristen Nygaard in recognition of their pioneer- ing work on object-oriented programming, are being awarded for the fourth time this year. We wish to thank all those who are organizing workshops, giving tutori- als, presenting demonstrations or offering posters for their significant efforts, all of which contribute to the richness of the ECOOP tapestry. ECOOP 2008 is being organized by the University of Cyprus. It is being held under the auspices of AITO, the Association Internationale pour les Technologies Objets, in cooperation with ACM, SIGPLAN and SIG- SOFT. The conference would not have been possible without the financial sup- port of sponsors. Special thanks go to our Silver Sponsors Google, IBM and Microsoft Research. Enjoy ECOOP 2008! Enjoy your stay in Paphos! George A. Papadopoulos on behalf of the Organizing Committee SENIOR PRIZE Prizes Dahl-Nygaard Aito Akinori Yonezawa systematically developed theories and prac- tical implementations for concurrent object-oriented lan- guages, from the early incarnation of Actors in the late 70’s to the ABCL language series in the early 90’s, eventually lead- ing to the seminal book "Object-Oriented Concurrent Pro- gramming", published with Mario Tokoro in 1987. His con- tributions to concurrent object-oriented languages range from theoretical foundations and massively parallel and effi- cient implementations of programs, to incorporating compu- tational reflection in concurrent language designs – long be- fore reflection was considered mainstream in object-oriented languages. In his work on theoretical foundations, he tackled the problem of formalizing the notion of concurrent objects in various ways, defining succinct operational semantics for concurrent objects using higher-order calculi and other forms of logical systems, such as linear logic, to provide the much needed rigor to the discipline of concurrent object program- ming. On the implementation side, in the early 90’s he lead the team that implemented several variants of ABCL on su- percomputers such as the Fujitsu AP1000 that embodied 512 nodes which was by far one of the largest and fastest parallel supercomputers in those days. He was also the first person to suggest a model of computational reflection for concurrent objects, and continuously extended the work so that reflec- tive capabilities became both functionally powerful and effi- ciently implementable in today’s object oriented program- ming languages and systems. With JavaGo, he has continued to contribute in the area of object mobility and concurrency. 2 JUNIOR PRIZE Wolfgang De Meuter has shown promising potential as a young researcher by proposing innovative ideas and by prov- ing that these are conceptually sound and realistically imple- mentable. He has focused his research and teaching on sev- eral different concepts such as formal semantics of proto- type-based languages, innovation in AOP (e.g., monads for AOP and jumping aspects giving rise to cflow), and more recently programming languages for ambient systems. In his Ph.D. dissertation on "Move Considered Harmful: A Lan- guage Design Approach to Mobility and Distribution for Open Networks", he proposes a new conceptual model for strong code mobility in prototype-based object-oriented sys- tems. The Ph.D. was the precursor of the AmbientTalk lan- guage that was recently developed by Wolfgang and his stu- dents. The language targets ambient-oriented environments where failure is the rule rather than the exception. It sup- ports new service discovery techniques, techniques to deal Aito Dahl-Nygaard Prizes Dahl-Nygaard Aito with knowledge that is distributed over volatile connections, and advanced remote object referencing techniques, as well as replication and reversible computations. Like Dahl and Nygaard, Wolfgang challenges students to look at new things, be it virtual machine technology or context-aware programming, with a disciplined questioning eye. And he is not afraid to challenge old established concepts as witnessed by the title of his Ph.D. He encourages the development of sound concepts backed with the practice of prototype imple- mentations in preparing a new generation of researchers. He also continues to work toward putting dynamic languages back on the scientific agenda. 3 MONDAY, JULY 7TH Workshops WS1 International Workshop on Aliasing, Confinement and Ownership in object-oriented programming (IWACO) Room: Akamas A WS2 International Workshop on Multiparadigm Program- ming with Object-Oriented Languages (MPOOL) Room: Akamas B WS3 Reflection, AOP and Meta-Data for Software Evolu- tion (RAM-SE) Room: Akamas C WS4 Fifth European Lisp Workshop (ELW) Room: Aphrodite A WS5 3rd Workshop on Implementation, Compilation, Optimization of Object-Oriented Languages, Programs and Systems (ICOOOLPS) Room: Aphrodite B 4 TUESDAY, JULY 8TH WS6 Tenth Workshop on Formal Techniques for Java-like Programs (FTfJP) Room: Akamas B WS7 International Workshop on Advanced Software De- velopment Tools and Techniques (WASDeTT) Workshops Workshops Room: Akamas C WS8 Parallel/High-Performance Object-Oriented Scien- tific Computing workshop (POOSC) Room: Aphrodite A WS9 Aspects, Dependencies, and Interactions Workshop (ADI) Room: Aphrodite B WS10 2nd International Workshop on Equation-Based Ob- ject-Oriented Languages and Tools (EOOLT) Room: Leda WS11 Twelfth Workshop on Quantitative Approaches on Object Oriented Software Engineering (QAOOSE 2008) Room: Athena WS12 PhD Workshop Room: Zeus 5 WEDNESDAY, JULY 9TH papers Technical 8:00 - 9:00 Registration 9:00 - 10:00 Invited Talk The Return of Transactions Rachid Guerraoui - EPFL, Switzerland Major chip manufacturers have recently shifted their focus from speeding individual processors to multiplying them on the same chip and shipping multicore architectures. Boosting the performance of programs will thus necessarily go through parallelizing them. This is not trivial and the aver- age programmer will badly need abstractions for synchronizing concur- rent accesses to shared memory objects. The transaction abstraction looks promising for this purpose and there is a lot of interest around its use in modern parallel programming. This talk will investigate whether the "return" of the old transaction idea brings any interesting research ques- tion, especially

  • Object-Oriented Programming Basics with Java
    Object-Oriented Programming Object-Oriented Programming Basics With Java In his keynote address to the 11th World Computer Congress in 1989, renowned computer scientist Donald Knuth said that one of the most important lessons he had learned from his years of experience is that software is hard to write! Computer scientists have struggled for decades to design new languages and techniques for writing software. Unfortunately, experience has shown that writing large systems is virtually impossible. Small programs seem to be no problem, but scaling to large systems with large programming teams can result in $100M projects that never work and are thrown out. The only solution seems to lie in writing small software units that communicate via well-defined interfaces and protocols like computer chips. The units must be small enough that one developer can understand them entirely and, perhaps most importantly, the units must be protected from interference by other units so that programmers can code the units in isolation. The object-oriented paradigm fits these guidelines as designers represent complete concepts or real world entities as objects with approved interfaces for use by other objects. Like the outer membrane of a biological cell, the interface hides the internal implementation of the object, thus, isolating the code from interference by other objects. For many tasks, object-oriented programming has proven to be a very successful paradigm. Interestingly, the first object-oriented language (called Simula, which had even more features than C++) was designed in the 1960's, but object-oriented programming has only come into fashion in the 1990's.

    Noname manuscript No. (will be inserted by the editor) Turing Award elites revisited: patterns of productivity, collaboration, authorship and impact Yinyu Jin1 · Sha Yuan1∗ · Zhou Shao2, 4 · Wendy Hall3 · Jie Tang4 Received: date / Accepted: date Abstract The Turing Award is recognized as the most influential and presti- gious award in the field of computer science(CS). With the rise of the science of science (SciSci), a large amount of bibliographic data has been analyzed in an attempt to understand the hidden mechanism of scientific evolution. These include the analysis of the Nobel Prize, including physics, chemistry, medicine, etc. In this article, we extract and analyze the data of 72 Turing Award lau- reates from the complete bibliographic data, fill the gap in the lack of Turing Award analysis, and discover the development characteristics of computer sci- ence as an independent discipline. First, we show most Turing Award laureates have long-term and high-quality educational backgrounds, and more than 61% of them have a degree in mathematics, which indicates that mathematics has played a significant role in the development of computer science. Secondly, the data shows that not all scholars have high productivity and high h-index; that is, the number of publications and h-index is not the leading indicator for evaluating the Turing Award. Third, the average age of awardees has increased from 40 to around 70 in recent years. This may be because new breakthroughs take longer, and some new technologies need time to prove their influence. Besides, we have also found that in the past ten years, international collabo- ration has experienced explosive growth, showing a new paradigm in the form of collaboration.

  • Ole-Johan Dahl
    Ole-Johan Dahl Born October 12, 1931, Mandal, Norway; with Kristen Nygaard, developer of the SIMULA programming language, which introduced classes and inheritance into the field of programming languages. Education: MS, numerical mathematics, University of Oslo, 1957. Professional Experience: Norwegian Defense Research Establishment (NDRE), 1952-1963; Norwegian Computing Center, 1963-1968; professor, computer science, University of Oslo, 1968-present. Dahl worked with the Norwegian Defense Research Establishment (NDRE) from 1952 to 1963 in computing and programming under Jan V. Gatwick. From 1956 onwards his main activity was software development. His master's thesis (“Numerical Mathematics,” 1957, University of Oslo) addressed the representation and manipulation of multidimensional arrays on a two-level store computer. His main contribution at the NDRE was a high-level programming language, MAC, used locally during the 1960s (first specification was dated 1957; the implemented version was modified as a result of the Algol effort). In 1963 he joined the Norwegian Computing Center for full-time work on SIMULA, and in 1968 he became a professor of computer science, then a new discipline at the University of Oslo. His main research during recent years has been in the areas of program architecture, specification tools, and verification techniques. From 1964 to 1976 he was the Norwegian delegate to IFIP Technical Committee 2 (Programming Languages), and from 1970 to 1977 he was a working member of IFIP Working Group 2.2 (Language Definition). He has been a member of IFIP Working Group 2.3 (Programming Methodology) since its founding in Oslo in 1969.1 BIBLIOGRAPHY Biographical Nygaard, Kristen, and Ole-Johan Dahl, “The Development of the SIMULA Languages,” in Wexelblat, Richard L., ed., History of Programming Languages, Academic Press, New York, 1981.

  • Object-Oriented Programming in the Beta Programming Language
    OBJECT-ORIENTED PROGRAMMING IN THE BETA PROGRAMMING LANGUAGE OLE LEHRMANN MADSEN Aarhus University BIRGER MØLLER-PEDERSEN Ericsson Research, Applied Research Center, Oslo KRISTEN NYGAARD University of Oslo Copyright c 1993 by Ole Lehrmann Madsen, Birger Møller-Pedersen, and Kristen Nygaard. All rights reserved. No part of this book may be copied or distributed without the prior written permission of the authors Preface This is a book on object-oriented programming and the BETA programming language. Object-oriented programming originated with the Simula languages developed at the Norwegian Computing Center, Oslo, in the 1960s. The first Simula language, Simula I, was intended for writing simulation programs. Si- mula I was later used as a basis for defining a general purpose programming language, Simula 67. In addition to being a programming language, Simula1 was also designed as a language for describing and communicating about sys- tems in general. Simula has been used by a relatively small community for many years, although it has had a major impact on research in computer sci- ence. The real breakthrough for object-oriented programming came with the development of Smalltalk. Since then, a large number of programming lan- guages based on Simula concepts have appeared. C++ is the language that has had the greatest influence on the use of object-oriented programming in industry. Object-oriented programming has also been the subject of intensive research, resulting in a large number of important contributions. The authors of this book, together with Bent Bruun Kristensen, have been involved in the BETA project since 1975, the aim of which is to develop con- cepts, constructs and tools for programming.

  • Software Education for Changing Computing Technology
    Software Education for Changing Computing Technology Benjamin Cooper1 and Steve E. Watkins2 1 CMC Technologies Limited LLC and 2Missouri University of Science and Technology Abstract Software education has been dominated by procedural-based programming languages such as BASIC, FORTRAN and C, and before that, the assembly languages. The primary reason that this methodology has held such sway in education was that it allowed quick action for the first major users of computers. This approach was the most straight-forward means of utilizing hardware that, over the last 60 years, has gotten faster and more complex through smaller and more densely packed elements. However, traditional advances as described by Moore’s law are now reaching both physical and economic limits. Pure object-oriented programming approaches offer benefits for hardware that is highly parallel and that is of non-traditional design. This work describes the evolution of computational technology, explores features of pure object-oriented languages such as Squeak Smalltalk, and discusses proactive curricula options. Introduction Programming literacy and proficiency are key curricula concerns whether as an independent specialty or as a fundamental component of other engineering specialties. Software education typically emphasized procedural-based programming languages. Such programming approaches, which use sequential calculations and simple decision-making processes, are the traditional option, but they are not the only possible methodology. Alternative approaches have been explored with advanced features. Also, software choices are not unrelated to the hardware. Improvements in computational capabilities require both hardware and software considerations. Students that are educated today must be prepared for the next generation of digital technologies.
