Its aim was to equip Master's students embarking on a bioinformatics course with a comprehensive set of programming skills and an appreciation of some of the fundamental issues in computing. The module was built around a five-day taught component, supplemented by a background reading exercise and a short project. We discuss the circumstances in which the module was created, the thinking behind our choice of content, the means of presentation, and the outcome of the teaching and learning process. Further we identity some of the lessons learnt from the experience.","PeriodicalId":120999,"journal":{"name":"PPPJ/IRE","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127607872","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 mixin based programming classes are defined which support particular roles or capabilities, which may require to be attached to a number of other classes. Mixin classes can be composed dynamically so that composite objects with differing combinations of roles and capabilities may be created without redundancy. Implementing the mixin concept in C++ is straightforward, using the parameterized inheritance capabilities provided by C++ templates. In standard Java it is not possible to use this approach because Java does not currently provide templates. But the Java language has other powerfull facilities, of which one is reflection. In this paper we outline an approach to mixin programming in Java, which is subject to ongoing development and which is based on exploiting Java's reflection capabilities.","PeriodicalId":120999,"journal":{"name":"PPPJ/IRE","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131063645","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}

Java bytecode offers a compact representation and ease of interpretation (fast-compilation); SafeTSA offers amenability to optimization. We use program profiling to guide format selection at the method-level. Methods deemed \"hot\" are those for which optimization should be expended and as such, are encoded using the SafeTSA format. All other methods are encoded using bytecode. Our hybrid format exploits the benefits of each constituent format to reduce compilation, execution, and transfer overhead.","PeriodicalId":120999,"journal":{"name":"PPPJ/IRE","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116462551","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 gateway exports an \"FTP file system\" to NFS clients. Once this file system is mounted on a client machine, files and directories accessible through the FTP protocol on any FTP server on the Internet appear as local files on the machine's file system. All existing programs can then transparently access these files for both reading and writing. Both anonymous and authenticated FTP access are supported.The gateway is implemented in Java and is thus platform independent. The design of the gateway allows Support for other file access protocols such as HTTP to be easily added. Performance experiments indicate an acceptable extra overhead while accessing files through the gateway.","PeriodicalId":120999,"journal":{"name":"PPPJ/IRE","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129523846","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}
