FaceMashup: An end-user development tool for social network data

Every day, each active social network user produces and shares texts, images and videos. While developers can access such data through application programming interfaces (APIs) for creating games, visualizations and routines, end users have less control on such information. Their access is mediated by the social application features, which limits them in combining sources, filtering results and performing actions on groups of elements. In order to fill this gap, we introduce FaceMashup, an end user development (EUD) environment supporting the manipulation of the Facebook graph. We describe the tool interface, documenting the choices we made during the design iterations. Data types are represented through widgets containing user interface (UI) elements similar to those used in the social network application. Widgets can be connected with each other with the drag and drop of their inner fields, and the application updates their content. Finally, we report the results of a user-test on the FaceMashup prototype, which shows a good acceptance of the environment by end-users

Perancangan Aplikasi Learning By Doing Interaktif Untuk Mendukung Pembelajaran Bahasa Pemrograman

AbstrakPembelajaran bahasa pemrograman adalah salah satu mata kuliah dasar untuk mengembangkan kompetensi keahlian pemrograman di bidang teknik Informatika, salah satunya adalah mata kuliah Algoritma dan Pemrograman. Sesuai dengan analisis instruksional, mata kuliah ini memberikan kompetensi tentang konsep dasar Algoritma Pemrograman yang akan menjadi dasar bagi pengembangan dan penerapan mata kuliah-mata kuliah selanjutnya. Banyak mahasiswa kurang memahami dasar-dasar pemrograman, sehingga menemui kesulitan ketika mengerjakan tugas-tugas mata kuliah yang membutuhkan keahlian pemrograman.Melalui inovasi pembelajaran ini, dikembangkan sebuah media pembelajaran baru dan interaktif bagi mahasiswa dengan mengintegrasikan berbagai faktor yang mempengaruhi permasalahan yang telah disebutkan sebelumnya. Aplikasi learning by doing interaktif untuk mendukung pembelajaran bahasa pemrograman ini dibangun menggunakan pendekatan Web Framework menggunakan Codeigniter. Aplikasi ini juga memanfaatkan fitur share kode pemrograman yang dikembangkan oleh Trinket. Hasil penelitian menunjukan bahwa kebermanfaatan aplikasi ini mampu membuat ketertarikan tehadap belajar pemrograman sebesar 79%. Ketertarikan yang tinggi ini membuat mahasiswa sering mencoba kode-kode program secara mandiri sehingga jumlah mahasiswa yang lulus dengan kemampuan baik selisihnya 14% dibandingkan dengan pembelajaran biasa.Kata kunci: bahasa pemrograman, pembelajaran, learning by doing, trinket AbstractLearning programming language is one of the basic courses to develop the competence of programming skills in Informatics engineering, one of which is the course of Algorithm and Programming.Based on instructional analysis, this lectures provides competence on the basic concepts of Programming Algorithm which will be the basis for the development and application of further lectures.

Using Clustering Techniques to Guide Refactoring of Object-Oriented Classes

Much of the cost of software development is maintenance. Well structured software tends to be cheaper to maintain than poorly structured software, because it is easier to analyze and modify. The research described in this thesis concentrates on determining how to improve the structure of object-oriented classes, the fundamental unit of organization for object-oriented programs. Some refactoring tools can mechanically restructure object-oriented classes, given the appropriate inputs regarding what attributes and methods belong in the revised classes. We address the research question of determining what belongs in those classes, i.e., determining which methods and attributes most belong together and how those methods and attributes can be organized into classes. Clustering techniques can be useful for grouping entities that belong together; however, doing so requires matching an appropriate algorithm to the domain task and choosing appropriate inputs. This thesis identifies clustering techniques suitable for determining the redistribution of existing attributes and methods among object-oriented classes, and discusses the strengths and weaknesses of these techniques. It then describes experiments using these techniques as the basis for refactoring open source Java classes and the changes in the class quality metrics that resulted. Based on these results and on others reported in the literature, it recommends particular clustering techniques for particular refactoring problems. These clustering techniques have been incorporated into an open source refactoring tool that provides low-cost assistance to programmers maintaining object-oriented classes. Such maintenance can reduce the total cost of software development

Model Transformation Languages with Modular Information Hiding

Model transformations, together with models, form the principal artifacts in model-driven software development. Industrial practitioners report that transformations on larger models quickly get sufficiently large and complex themselves. To alleviate entailed maintenance efforts, this thesis presents a modularity concept with explicit interfaces, complemented by software visualization and clustering techniques. All three approaches are tailored to the specific needs of the transformation domain
