Software product lines (SPLs) and adaptive systems aim at variability to cope with changing requirements. Variability can be described in terms of features, which are central for development and configuration of SPLs. In traditional SPLs, features are bound statically before runtime. By contrast, adaptive systems support feature binding at runtime and are sometimes called dynamic SPLs (DSPLs). DSPLs are usually built from coarse-grained components, which reduces the number of possible application scenarios. To overcome this limitation, we closely integrate static binding of traditional SPLs and runtime adaptation of DSPLs. We achieve this integration by statically generating a tailor-made DSPL from a highly customizable SPL. the generated DSPL provides only the runtime variability required by a particular application scenario and the execution environment. the DSPL supports self-configuration based on coarse-grained modules. We provide a feature-based adaptation mechanism that reduces the effort of computing an optimal configuration at runtime. In a case study, we demonstrate the practicability of our approach and show that a seamless integration of static binding and runtime adaptation reduces the complexity of the adaptation process.

Smooth integration of domain-specific languages into a general purpose host language requires absorbing of domain code written in arbitrary syntax. the integration should cause minimal syntactical and semantic overhead and introduce minimal dependency on external tools. In this paper we discuss a DSL integration technique for the C++ programming language. the solution is based on compile-time parsing of the DSL code. the parser generator is a C++ template metaprogram reimplementation of a runtime Haskell parser generator library. the full parsing phase is executed when the host program is compiled. the library uses only standard C++ language features, thus our solution is highly portable. As a demonstration of the power of this approach, we present a highly efficient and type-safe version of printf and the way it can be constructed using our library. Despite the well known syntactical difficulties of C++ template metaprograms, building embedded languages using our library leads to self-documenting C++ source code.

Service component Architecture specification (SCA) is an emerging and promising technology for the development, deployment and integration of Internet applications. this technology supports the management of dynamic availability and treats the heterogeneity between the components of distributed applications. However, this technology is not able to solve all problems. Currently, software systems are evolving. this factor makes development and maintenance of systems more complex than before. One solution to remedy this was the use of the Model Driven engineering (MDE) approach in the development process. the aim of this paper is to apply an MDE automation type ensuring the passage from an UML 2.0 model to SCA model. To achieve this, we study two metamodels: the UML 2.0 component metamodel and the SCA meta-model. To ensure traceability between these two meta-models, we have defined transformation rules in ATL language. © 2011 IEEE.

Lightweight Modular Staging: A Pragmatic Approach to Runtime Code Generation and Compiled DSLs

Software engineering demands generality and abstraction, performance demands specialization and concretization. generative programming can provide both, but developing high-quality program generators takes a large effort, even if a multi-stage programming language is used. We present lightweight modular staging, a library-based multi-stage programming approach that breaks with the tradition of syntactic quasi-quotation and instead uses only types to distinguish between binding times. through extensive use of component technology, lightweight modular staging makes an optimizing compiler framework available at the library level, allowing programmers to tightly integrate domain-specific abstractions and optimizations into the generation process. We argue that lightweight modular staging enables a form of language virtualization, i.e. allows to go from a pure-library embedded language to one that is practically equivalent to a stand-alone implementation with only modest effort.

there is only that much space in the CS curriculum, and there are always new subjects that should be accommodated by the curriculum. For instance, in our community, we would want all graduates to leave university with a modest background in technical spaces, software languages, and meta-programming;also, with conceptually informed and reasonably timeless skills to efficiently master related programming techniques and technologies. In reality, the curricula of few CS departments meet this expectation. In this talk, I will discuss such curricula-related expectations of our community and the suboptimal situation at CS departments-as I perceive them. More importantly, I will allude to a revision of the CS curriculum that could optimize matters and may stand a chance for mid-term adoption.

this paper investigates the employment of a Genetic Algorithm to optimally configure the parameters of a neural network architecture. Specifically, the issue of optimising the input connectivity or "connectivity map" for a class of weightless artificial neural networks is investigated by employing a genetic algorithm to intelligently 'search' the significantly large problem space, thereby reducing the potential for poor results based solely on a bad network layer group. this study takes as its example the mapping of independently produced solutions to programming exercises from a diverse range of specifications to the specification from which the implementation was derived. An important component of this technique lies in the crossover and mutation algorithms within the genetic algorithm, which have been specifically designed for this system. the results show significant promise for what is a novel and challenging problem domain for artificial neural systems.

Adding Genericity to a Plug-in Framework

Plug-in components are a means for making feature-rich applications customizable. Combined with plug-and-play composition, end users can assemble customized applications without programming. If plug-and-play composition is also dynamic, applications can be reconfigured on the fly to load only components the user needs for his current work. We have created ***, a plug-in framework that supports dynamic plug-and-play composition. the basis for plug-and-play in Plux is the composer which replaces programmatic composition by automatic composition. components just specify their requirements and provisions using metadata. the composer then assembles the components based on that metadata by matching requirements and provisions. When the composer needs to reuse general-purpose components in different parts of an application, the component model requires genericity. the composer depends on metadata that specify which components should be connected and for general-purpose components those metadata need to be different on each reuse. We present an approach for generic plug-ins with component templates and an implementation for Plux. the general-purpose components become templates and the templates get parameterized when they are composed.

A component-based Run-time Evolution Infrastructure for Resource-Constrained Embedded Systems

this paper deals with embedded systems software and the modification of its architecture and behavior at execution-time. Incautious implementation of these features demands both heavy memory and performance overrun. To accomplish such software evolution activities in resource-constrained embedded systems, we propose a component-based run-time evolution infrastructure that reconciles richness of evolution alternatives and performance requirements. Our proposal is based on off-site components reifications, which are representations of components that allow us to treat evolution concerns remotely. Hence, the workload to be processed by the embedded device is alleviated. Memory and processor-time resources consumption evaluation on a real-world scenario show the efficiency and pertinence of our approach.

Code Clones in Feature-Oriented Software Product Lines

Some limitations of object-oriented mechanisms are known to cause code clones (e. g., extension using inheritance). Novel programming paradigms such as feature-oriented programming (FOP) aim at alleviating these limitations. However, it is an open issue whether FOP is really able to avoid code clones or whether it even facilitates (FOP-related) clones. To address this issue, we conduct an empirical analysis on ten feature-oriented software product lines with respect to code cloning. We found that there is a considerable number of clones in feature-oriented software product lines and that a large fraction of these clones is FOP-related (i.e., caused by limitations of feature-oriented mechanisms). Based on our results, we initiate a discussion on the reasons for FOP-related clones and on how to cope with them. We show by means of examples how such clones can be removed by applying refactorings.
