Software developers in these projects collaborate via FOSS informalisms, i.e. mailing list, bug repository and code repository. Analysing the human collaborative work of these software developers over a time period, e.g. five years, sheds light on the underlying structure and dynamics of how the software is being developed, how the project is led, who the influencers are, and how to achieve a state of sustainability. In this paper, we propose to use temporal social network analysis with temporal visualization to study the evolution and social dynamics of FOSS communities. With these techniques we aim to identify measures associated with unhealthy group dynamics, e.g. a simmering conflict, as well as early indicators of major events in the lifespan of a community. One dynamic we are especially interested in, are those of forked FOSS projects. We used the results of a study of forked FOSS projects by [Robles and Gonzalez-Barahona 2012] as the starting platform for our study, and tried to gain a better understanding of the evolution of these communities.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126914913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a fluid dynamics problem is considered and an example of a *AIDA program for fluid flow simulation is provided. The program is presented as a set of information resources oriented not only to the executable code generation, but also to an explanation of the problem and its application algorithm. Various features of the *AIDA program are discussed and some comparisons with a Fortran equivalent are performed.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124070025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Online open source repositories provide scripts available for reuse. Yet just because these scripts are open source does not mean they are all reusable: many are specialized and irrelevant to most peoples' needs, while others are hard to understand or learn from. Repositories offer keyword-based search engines to find scripts relevant to specialized needs, but they lack any means for filtering search results according to reusability. To address this shortcoming, we present an approach for creating a model to automatically estimate the reusability of web automation scripts. To test this approach, we prototyped a search engine that uses these reusability estimates to sort one particular kind of web automation scripts, CoScripter macros, according to reusability. An empirical evaluation confirmed that the system's reusability estimates are significantly correlated with user perceptions of macro reusability, thus implying that our approach presents a viable means for helping end-user programmers to find reusable web automation scripts.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117282266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While undoubtedly a milestone, all of this occurs at the expense of high energy costs needed to supply servers, data centers, and any use of computers. Associated with these high energy costs is the emission of greenhouse gases. These two issues have become major problems in society. The ICT sector contributes up to 8% of the overall energy consumption, with 50% of the energy costs of an organization being attributed to the IT departments.The paper discusses a tool which applies the proposed techniques on software code. This tool would guide the developer into programming more energy-aware software by alerting him/her of red smells, and offering green refactorings, all this in a simple visual layout to allow the software developer to become energy-aware. This application will also provide the ability to navigate between less energy efficient areas (packages, classes, modules, functions, methods, blocks and even lines), making its implementation more energy efficient.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"463 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132305804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a principled approach to teach programming using a debugging game called Gidget, which was created using a unique set of seven design principles. A total of 44 teens played it via a lab study and two summer camps. Principle by principle, the results revealed strengths, problems, and open questions for the seven principles. Taken together, the results were very encouraging: learners were able to program with conditionals, loops, and other programming concepts after using the game for just 5 hours.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114703623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We enhance here their capabilities by including references to resources that are required to persist in some state or to perform some state transition. To this end, we introduce a notion of annotation, which can be expressed through a restriction of Conceptual Spider Diagrams (extended over domains), where domains are partially ordered and predicate edges have to be consistent with this ordering. The resulting notion of Annotated Modeling Spider Diagrams can then be used to express constraints on the usage of resources, so that conformance to a policy can be verified with respect to resource availability. We provide additional options for user-modelling choices via a natural equivalent representation in terms of (classical) Spider Diagrams, restricted on the domain of interest, and the use of colour for domain identification.","PeriodicalId":165006,"journal":{"name":"2014 IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125331293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
