Changes to ECMAScript, Part 2: Harmony Highlights – Proxies and Traits
Google Tech Talk April 20, 2010 ABSTRACT Presented by Tom Van Cutsem. We discuss two proposed language features for inclusion in ECMAScript-Harmony. The first, dynamic proxies, enables Javascript programmers to create proxy objects that can intercept property access, assignment, enumeration, etc. It is a powerful metaprogramming mechanism that provides a standard API for creating generic wrappers for transparent access control, implementing legacy API adaptors, profilers, lazy initialization, etc. The second part of the talk introduces a traits library for ECMAScript 5. Traits are a more robust alternative to multiple inheritance or mixin-based composition. Based on ECMAScript 5's new "property descriptor" API, we built a portable lightweight library that supports trait-based object composition. We discuss the limitations of introducing traits using a library approach and highlight the benefits of direct support for traits in ECMAScript-Harmony.

His research focus is on programming language design and implementation, with an emphasis on metaprogramming, concurrent and distributed programming. He is co-designer of the distributed scripting language AmbientTalk. Tom is currently on a six-month Visiting Faculty appointment at Google in MTV, cooperating with Mark Miller on <b>…</b>

Anders Hejlsberg opens the developer keynote at TechDays 2010 in Belgium with: ‘Trends and future directions in programming languages’, on March 31st 2010. In this keynote Anders discusses the paradigms and future directions in programming languages.

About Anders Hejlsberg:

Anders Hejlsberg is a Technical Fellow in the Developer Division. He is an influential creator of development tools and programming languages. He is the chief designer of the C# programming language and a key participant in the development of the Microsoft .NET framework. Since its initial release in 2000, the C# programming language has been widely adopted and is now standardized by ECMA and ISO. Before his work on C# and the .NET framework, Hejlsberg was an architect for Visual J++ development and the Windows Foundation classes.  Before joining Microsoft in 1996, Hejlsberg was one of the first employees of Borland International Inc. As principal engineer, he was the original author of Turbo Pascal, a revolutionary integrated development environment, and chief architect of its successor, Delphi.  Hejlsberg co-authored “The C# Programming Language”, published by Addison Wesley, and has received numerous software patents. In 2001, he was the recipient of the prestigious Dr. Dobbs Excellence in Programming Award.  He studied engineering at the Technical University of Denmark.

C9 Conversations: Yuri Gurevich On Logic, Imperative, Abstraction and Algorithms

Welcome to the latest installment of C9 Conversations. For this episode, we were very fortunate to get a chance to converse openly with one of the world’s preeminent mathematical logicians, the great Yuri Gurevich.

Dr. Gurevich is Professor Emeritus of Electrical Engineering and Computer Science at the University of Michigan. He is currently a principle research scientist in Wolfram Schulte’s RiSE team (Research in Software Engineering group at Microsoft Research).

Originally, Dr. Gurevich started his career as an algebraist. Later he became a logician. Then he moved to computer science, where his main projects have been Abstract State Machines, Average Case Computational Complexity, and Finite Model Theory. Dr. Gurevich has been honored as a Dr. Honoris Causa of the University of Limburg, Belgium (1998), as a Fellow of the Association for Computing Machinery (1996), as well as a Fellow of the John Simon Guggenheim Memorial Foundation (1995).

Dr. Gurevich’s fundamental work on the theory of Abstract State Machines (ASMs) is of paramount importance for theoretical and applied computer science. The significance of the theoretical concepts developed by Gurevich is confirmed by the substantial impact they have on mathematical modeling of discrete dynamic systems.

*This is probably the only interview in C9’s history where a good case is made for imperative programming versus declarative and functional (this starts right off the bat at around 02:31).
