They show dependencies and contexts in which design decisions were made, supporting programmers in understanding systems and helping them to recognize disadvantageous design decisions. IslandViz visualizes OSGi-based software architectures in Virtual Reality using an island metaphor; for now, the history of an architecture is not taken into account. We show how IslandViz can be extended to include changes on package and compilation unit level by changing the layout of islands. For this purpose we adapt the Enhanced Hexagon Tiling Algorithm and create growth corridors for each region of an island. As a result, island regions can change along with their respective packages without the possibility of being enclosed by other regions.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115633805","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}

The key idea of structured code editors is to constrain editing to syntactically valid program code, that is, the modifications ensure that the source code always conforms to the grammar. Syntax is considered an entry barrier when learning how to program. In this work we rehash the concept of structured code editors targeting programming education. We present Javardise, a structured editor for a subset of the Java language, and discuss its features in the light of programming pedagogy.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126663737","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}

A key feature of the streams framework is enabling parallelizing a computation as easy as calling a single method. Still, developers should test whether parallelizing a stream may results in performance, liveness or safety hazards. While such issues are mainly observable at runtime, there is a lack of tools capturing information that enable understanding the dynamic behavior of a stream application. In this extended abstract, we devise a profiler focused on characterizing dynamic attributes of a stream application running on a single JVM in a shared-memory multicore. Our tool aims at collecting runtime information and key metrics to support analysis of sequential and parallel stream processing, towards helping developers make better decisions to efficiently and safely use the streams framework.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114386396","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}

The programs’ outputs are digital architectural 3D models, which are visual by nature and, therefore, benefit from immersive visualization. Live Coding in Virtual Reality (LCVR) is a methodology for the interactive development of AD programs while immersed in Virtual Reality (VR), favoring a more intuitive development process for architectural designs. However, complex buildings tend to require complex AD programs and, despite the added visual aid, as programs grow in complexity, it becomes harder to understand which parts of the program were responsible for which parts of the model. Moreover, LCVR introduces a new level of complexity: interaction with both model and program in VR. This research proposes to ease the programming task for architects who wish to code their models in VR, by supporting program comprehension in the LCVR workflow with traceability and refactoring mechanisms. These features will help users interact with their designs from within the virtual environment.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116657793","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}

Unified and split are two popular textual representations supported by clients for source code management. Whether these representations differ in supporting source code commit assessment is still unknown, despite its ubiquity in software production environments. This paper performs a controlled experiment to test the causality between the textual representation of source code differences and the performance in term of commit evaluation. Our experiment shows that no significant difference was measured. We therefore conclude that both unified and split equally support the source code commit assessment for the tasks we considered.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123338872","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}

Spark relies on code generation to optimize the execution performance of SQL queries on a variety of data sources. Despite its already efficient runtime, Spark's code generation suffers from significant runtime overheads related to data de-serialization during query execution. Such performance penalty can be significant, especially when applications operate on human-readable data formats such as CSV or JSON.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116007121","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}

To allow efficient interactions within a projectional editor, it is necessary for the editor to clearly communicate the structure of the program to the user, such that it is clear what editing operations are supported for a given element. Making the abstract syntax tree visible within the editor may provide this clarity, however, it generally also results in considerably increased space usage, potentially also impacting usability. We present an early prototype of a tree-oriented projectional editor for Squeak/Smalltalk that tries to minimize space usage while retaining a clear visualization of the tree structure, balancing the two problems. We describe and discuss our design prototype and do a preliminary evaluation through individual account of experience working with the editor on various projects.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133354203","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}

Therefore, there is a need to guide developers in developing mobile applications in the most energy efficient way. One of the ways to improve this is to provide live feedback about the energy efficiency of a program while it's being programmed. We have analyzed and compared a total of 16 different tools and presented a list of 15 code smells and respective refactorings. From the analyzed tools, Leafactor is the closest to a valid solution to our problem because it's the only energy-aware tool with the highest liveness level. However, in order to be executed the programmer needs to trigger it on the IDE by selecting the file, instead of automatically being executed without the programmer being noticed and refactor his inefficient code.","PeriodicalId":373173,"journal":{"name":"Companion Proceedings of the 4th International Conference on Art, Science, and Engineering of Programming","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129031376","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}
