Summary
For decades, software engineering has "dreamed an impossible dream", to build software as easily as building Lego houses. In this talk, James Noble imagines a world where the dream has been realized, where software parts can be found in worldwide repositories, where most software is built by reusing existing software, and where we've finally been freed from the mundane necessity of programming.

Bio
James Noble is Professor of CS and SE at Victoria University of Wellington, New Zealand. His research centers around software design and is colored by longstanding interest in OO approaches to design, aliasing and object ownership, design patterns, agile methodology, via usability, visualization and computer music, to postmodernism and the semiotics of programming.

Many people assume that agile methods mean an absence of design. Design still happens in agile projects, but it shifts from an up-front phase to a continual evolution.
