General design issues in integration and programming have been covered in great detail in many pattern languages since the beginnings of the patterns movement, and service-oriented infrastructure design patterns have also been published in the last decade. However, the interface representations (i.e., the content of message payloads) have received less attention. We presented five structural representation patterns in our previous work; in this paper we continue our coverage of the API design space and propose five interface quality patterns that deal with the observable aspects of quality-attribute-driven interface design for efficiency, security, and manageability: An API Key allows API providers to identify clients. Providers may offer rich data contracts in their responses, which not all consumers might need. A Wish List allows the client to request only the attributes in a response data set that it is interested in. If a client makes many API calls, the provider can employ a Rate Limit and bill clients according to a specified Rate Plan. A provider has to provide a high-quality service while at the same time having to use its available resources economically. The resulting compromise is expressed in a provider's Service Level Agreement.","PeriodicalId":136534,"journal":{"name":"Proceedings of the 23rd European Conference on Pattern Languages of Programs","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117083384","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}

With the advent of the cloud, computing power shifted back again to centralized locations. In past decades, we have seen an alternation between centralization and decentralization. Although the cloud is highly scalable and performant, it exhibits limitations such as real-time capabilities. Fog computing is an approach that tries to overcome these shortcomings. The implementation guidelines for fog computing system are vague to be implemented in real-world applications. Smart objects at the edge benefit from low latency responses, location awareness, and higher availability provided by fog computing. In this paper, we present Fogxy, an architectural pattern for fog computing. It serves as an implementation guidance that describes a solution to a recurring problem in a given context. Fogxy is composed of different patterns and is based on the idea of the proxy pattern. Fogxy gives an overview of the implementation of fog computing applications and takes into account the integration of cloud computing and Internet of Things (IoT) technologies.","PeriodicalId":136534,"journal":{"name":"Proceedings of the 23rd European Conference on Pattern Languages of Programs","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121727968","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}

It is difficult to discover effective strategies because it takes a lot of trial and error before a teacher can conclude that a particular approach improves student learning. Researchers have used educational design patterns to encapsulate high-quality strategies that facilitate the transfer of pedagogical knowledge. In this work, we investigated the feasibility of utilizing three educational design patterns as a teaching tool for math preservice teacher education: Feedback Sandwich, Pitfall Diagnosis and Prevention, and Worked Examples. Specifically, we used design patterns to investigate how preservice teachers provided feedback to students who gave common wrong answers to a given math problem and compared their feedback before and after they were introduced to educational design patterns. Results indicated that design patterns helped preservice teachers consider other aspects of feedback such as students' self-regard, common misconceptions, and prior knowledge into their feedback for common wrong answers on math problems. The limited set of three design patterns introduced in the study focused on feedback presentation. Results also indicated preservice teachers may benefit from design patterns that address other aspects of feedback such as content granularity, feedback length, and presentation medium. Implications of this study, including the potential of using educational design patterns to improve preservice teacher education, are discussed.","PeriodicalId":136534,"journal":{"name":"Proceedings of the 23rd European Conference on Pattern Languages of Programs","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123778725","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}

Blockchain provides a shared infrastructure to execute programs, called smart contracts, and to store data. Since blockchain technologies are at an early stage, there is a lack of a systematic and holistic view on designing software systems that use blockchain. We view blockchain as part of a bigger system, which requires patterns for using blockchain in the design of their software architecture. In this paper, we collect a list of patterns for blockchain-based applications. The pattern collection is categorized into four types, including interaction with external world patterns, data management patterns, security patterns and contract structural patterns. Some patterns are designed considering the nature of blockchain and how it can be specifically introduced within real-world applications. Others are variants of existing design patterns applied in the context of blockchain-based applications and smart contracts.","PeriodicalId":136534,"journal":{"name":"Proceedings of the 23rd European Conference on Pattern Languages of Programs","volume":"396 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131679546","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}
