Increasingly, software is required to accommodate new features after the design and deployment stages. Applications are designed to improve their adaptability and flexibility. Software needs to evolve at runtime with minimal interruptions and, when possible, never stop running. Different motivations push software design to allow such evolution at runtime. For example, production systems with critical availability requirements need to be updated with little perceived execution interruption. This paper enumerates challenges in the construction of dynamic component-based applications that are capable of undergoing changes during execution, with minimal impact.

The evolution of software product lines (SPLs) is particularly challenging. SPL functionalities, usually decomposed into features, naturally depend among them. As the SPL evolves, the implementation of each feature dependency might increasingly affect more code elements. Therefore, as the complexity of feature dependency implementation grows up through code evolution, it is likely to negatively impact on the SPL stability. Stability refers to the amount of changes between SPL releases and it is directly influenced by the complexity of feature dependency implementation. In this context, a number of emerging programming techniques can be used to keep the complexity of feature dependency code under control. Nevertheless, there is a lack of studies analysing the impact of different programming techniques on the stability of feature dependency code in evolving SPLs. This paper presents a first exploratory analysis on the use of programming techniques to implement and evolve feature dependencies. Our analysis was developed in the context of three evolving SPL systems, which are made up of 210 feature dependencies. Our initial findings reveal that two particular types of feature dependency implementation using different programming techniques play a role in the SPL stability.

The creation of tools, techniques and methodologies to support the manipulation of large data sets has been receiving special attention of both scientific and industrial communities, in order to discover new ways of dealing with the underlying information, including learning purposes, identification of patterns, decision making support, amongst others. However, making use of computing resources to enhance awareness and understanding of software information and the software itself is still a challenge in software/systems engineering, since it involves the identification of suitable mechanisms, adequate abstractions, and studies on stimulation of the human perceptive and cognitive abilities. This paper presents some of the challenges in this context, based on current trends of software development lifecycle, program comprehension, and software engineering education. At the end, a special focus is given on ongoing research on using and improving current mechanisms for supporting software reuse practices and software comprehension in general.
