Global computing refers to computation over "global computers," i.e., com- tational infrastructures available globally and able to provide uniform services with variable guarantees for communication, cooperation and mobility, resource usage, security policies and mechanisms, etc., with particular regard to explo- ing their universal scale and the programmability of their services. As the scope and computational power of such global infrastructures continue to grow, it - comes more and more important to develop methods, theories and techniques for trustworthy systems running on global computers. This book constitutes the thoroughly refereed proceedings of the ?fth e- tion of the International Symposium on Trustworthy Global Computing (TGC 2010)thatwasheldinMunich, Germany, February24-26,2010.TheSymposium on Trustworthy Global Computing is an international annual venue dedicated to safe and reliable computation in global computers. It focuses on providing frameworks, tools, and protocols for constructing well-behaved applications and on reasoning rigorouslyabout their behavior and properties. The related models of computation incorporate code and data mobility over distributed networks with highly dynamic topologies and heterogeneous devices.

This volume contains the papers from the workshop "e;Radical Innovations of Software and Systems Engineering in the Future."e; This workshop was the ninth in the series of Monterey Software Engineering workshops for formulating and advancing software engineering models and techniques, with the fundamental theme of increasing the practical impact of formal methods. During the last decade object orientation was the driving factor for new system solutions in many areas ranging from e-commerce to embedded systems. New modeling languages such as UML and new programming languages such as Java and CASE tools have considerably in?uenced the system development techniques of today and will remain key techniques for the near future. However, actual practice shows many de?ciencies of these new approaches: - there is no proof and no evidence that software productivity has increased with the new methods; - UML has no clean scienti?c foundations, which inhibits the construction of powerful analysis and development tools; - support for mobile distributed system development is missing; - formanyapplications,object-orienteddesignisnotsuitedtoproducingclean well-structured code, as many applications show.

This monograph details several important advances in the direction of a practical proofs-as-programs paradigm, which constitutes a set of approaches to developing programs from proofs in constructive logic with applications to industrial-scale, complex software engineering problems.
