The Clarens Web Service Framework for Distributed Scientific Analysis in Grid Projects

Large scientific collaborations are moving towards service oriented architecutres for implementation and deployment of globally distributed systems. Clarens is a high performance, easy to deploy Web Service framework that supports the construction of such globally distributed systems. This paper discusses some of the core functionality of Clarens that the authors believe is important for building distributed systems based on Web Services that support scientific analysis

Towards using online portfolios in computing courses

The direct experience we had with teaching a summer pre-college computing course in which we adopted an online portfolio approach has led us to consider the use of online portfolios in our regular computer science undergraduate courses. The technical challenges we foresee include: the necessary support from the college\u27s IT department; the use of Microsoft-based web authoring technologies vs. the use of Open Source / freeware counterparts; the need for adequate technical knowledge on the part of our faculty; the need for server-side hardware and software resources
