Abstract
Graphical user interfaces (GUls) make software easy to use by providing the user with visual controls. Therefore, correctness of GUI's code is essential to the correct execution of the overall software. Models can help in the evaluation of interactive applications by allowing designers to concentrate on its more important aspects. This paper describes our approach to reverse engineer an abstract model of a user interface directly from the GUI's legacy code. We also present results from a case study. These results are encouraging and give evidence that the goal of reverse engineering user interfaces can be met with more work on this technique.

Abstract
This paper presents a web portal for the certification of open source software. The portal aims at helping programmers in the internet age, when there are (too) many open source reusable libraries and tools available. Our portal offers programmers a web-based and easy setting to analyze and certify open source software, which is a crucial step to help programmers choosing among many available alternatives, and to get some guarantees before using one piece of software. The paper presents our first prototype of such web portal. It also describes in detail a domain specific language that allows programmers to describe with a high degree of abstraction specific open source software certifications. The design and implementation of this language is the core of the web portal. © Springer-Verlag Berlin Heidelberg 2014.

Abstract
This paper presents techniques for the design and implementation of domain specific languages. Our techniques are based on higher-order attribute grammars. Formal languages are specified in the classical attribute formalism and domain specific languages are embedded in the specification via higher-order attributes. We present a domain specific language for pretty-printing and we show how such language can be easily embedded in the specification of a powerful spreadsheet-like tool. From such specification an incremental implementation is automatically derived and the first results are presented. © 2003 IEEE.
