Adaptive programming allows developers to write structureshy programs. However, in Adaptive programming, recursive computations are known to require a good deal of boiler plate code to express. This paper describes perobject visitors; a programming construct that allows developers to write recursive adaptive computations at a higher level of abstraction. This paper also describes a prototype implementation for perobject visitors.

Two important problems of object-oriented reuse are the propagation of design and implementation specifics of the base software to the inheritors, and the protection of the inheritors against changes in the base software. In this paper, we argue that the simple inheritance rules of existing object-orientedlanguages are not sufficient for properly dealing with these problems. In the proposal presented in this paper, programmers are enabled to make metalevel declarations of the internal protocols and dependencies of their classes. Additionally, changes of the base module are automatically monitored to filter out information about the alterations that may invalidate already existing inheritors. Based on these informations, the subclassing semantics is adjusted such that the maintenance of the base module properties and the protection of the inheritor is ensured during their integration. In this way, language support is provided for keeping the behavior of reusable software consistent during its evolution.

Web applications exemplify the need for generative programmingtechniques in part due to the many languages, artifacts, and groups of developers involved. Some problems remain, including those that that arise from the interplay with versioning. This paper proposes addressing these problems with structured program transformations, and explores a framework for the co-evolution of platform artifacts and the models that generate them.

This paper explains how patterns can be used to describe the implementation of other patterns. It is demonstrated how certain design patterns can describe their own design. This is a fundamental reflexive relationship in pattern relationships. The process of assembling patterns by other patterns is named pattern tiling. Tiling enables us to interweave simple understood concepts of patterns into their complex real-life implementation. Several pattern tilings for the Interpreter design pattern are illustrated.

Developing large software systems has largely become an exercise in integration. The main effort is writing "glue" that holds externally developed components together. We will explore the shift away from commercial off-the-shelf (COTS) to free/open source software (F/OSS) components, and identify the opportunities and issues introduced by it.
