A New Paradigm in Data Intensive Computing: Stork and the Data-Aware SchedulersThe unbounded increase in the computation and data requirements of scientific applications has necessitated the use of widely distributed compute and storage resources to meet the demand. In a widely distributed environment, data is no more locally accessible and has thus to be remotely retrieved and stored. Efficient and reliable access to data sources and archiving destinations in such an environment brings new challenges. Placing data on temporary local storage devices offers many advantages, but such “data placements” also require careful management of storage resources and data movement, i.e. allocating storage space, staging-in of input data, staging-out of generated data, and de-allocation of local storage after the data is safely stored at the destination. Traditional systems closely couple data placement and computation, and consider data placement as a side effect of computation. Data placement is either embedded in the computation and causes the computation to delay, or performed as simple scripts which do not have the privileges of a job.
The insufficiency of the traditional systems and existing CPU-oriented schedulers in dealing with the complex data handling problem has yielded a new emerging era: the data-aware schedulers. One of the first examples of such schedulers is the Stork data placement scheduler. In this paper, we will discuss the limitations of the traditional schedulers in handling the challenging data scheduling problem of large scale distributed applications; give our vision for the new paradigm in data-intensive scheduling; and elaborate on our case study: the Stork data placement scheduler. Index Terms— Scheduling, data-aware,Why C# and Why .NET In The Undergraduate Information Systems CurriculumConsidering the rapid pace of changes in the software field and the limited courses that a student can take in languages, the question is which languages are crucial for students to learn in an undergraduate IS curriculum. This paper investigates the necessity of teaching C# and .NET in the undergraduate IS curriculum. It explores the pros and cons of .Net versus J2EE for applications development and differences between C#, C++ and Java, and which one may be the best language for teaching first programming course in IS curriculum.
C# is Microsoft's latest object-oriented
programming language developed for .NET platform and .NET is Microsoft’s latest platform technology for creating web services. C# is a C++ based language and was developed to provide portability for distributed applications over network and internet. Application development in .NET platform can be done in multiple languages including C#, C++, and Visual Basic. Programs developed in all of these languages are compiled to Microsoft’s Intermediate Language (IL) and executed within Common Language Runtime (CLR). We explain the core elements of .NET and how web applications are developed and run with this technology. .NET is not a programming language; it's a virtual-machine technology (similar to Java virtual machine technology) with a framework that provides capability to run a variety of web applications. The .NET framework class library provides a set of classes that provide essential functionality for applications build within the .NET environment. Web functionality, XML support, database support, threading and distributed computing support is provided by the .NET frameworkTop 10 Reasons to Upgrade to Visual Studio 2008 Professional Edition1.

Among the villagers is a boy known as the most skillful rider in all the land. A boy who, it is expected, will one day take over the responsibility of leading Ordon as the village chief. His name is Link… Trusted and liked by all the villagers, Link is especially loved by the other children of Ordon, among whom he holds unofficial status as the leader of the pack. Link spends his days as a ranch hand and learns the ways of the sword from the village’s lone swordsman, Rusl, in his spare time. He often displays his newly honed skills to the village youths, which makes him even more popular.
One day Link is showing off his swordsmanship as usual, when a monkey appears. “Hey! That’s the monkey that’s been causing trouble all over the village! Let’s get him,” cry the children. They run after the monkey into the forest. Link rushes into the heart of the woods after them and is shocked to find that the dark thickets are teeming with countless monsters. After fighting his way through their ranks, Link rescues the child and the monkey from the cage where they are held captive. Until now, the forest had always been a safe place… The next day, after much encouragement by Rusl, Link prepares to set out and deliver the village’s tribute to Hyrule Castle.

The RoboJDE™ Java-enabled robotics software development environment (included with IntelliBrain) allows you to download the example mini-sumo robot application discussed here into your IntelliBrain controller. With RoboJDE you can modify the example mini-sumo application or write your own mini-sumo program to improve the competitiveness of the robot.
Mini-sumo is a competition between robots based on Japanese wrestling – “sumo” is the Japanese word for wrestling. Similar to traditional sumo matches, two opponents (robots) face each other in a ring named a dohyo – see Figure 1. The object is to stay in the ring while pushing the opposing robot out of the ring. The robot that stays in the ring the longest wins the match.
Mini-sumo robots are small autonomous mobile robots designed specifically for sumo style competition. The mini-sumo robot competition rules restrict the robot length and width to 10 cm x 10 cm, but do not restrict its height. In addition, the robot cannot weigh more than 500 grams. Unlike larger battle robots, mini-sumo robots are not allowed to damage the opponent robot, they are only allowed to push it off the dohyo.
All the hardware components you will need to build the robot discussed here are readily available. A mini-sumo robot can be assembled in a few hours or less. Once you have assembled your robot, you can load the mini-sumo example program included with the RoboJDEImplementing a Web-based Calendar TutorialThis tutorial is all about implementing a Web-based calendar using open source technology.

The goal is a fully functional high-performance mailsystem with user-administration with Web-cyradm, a webinterface. Data like virtualusers, aliases etc. are stored in a mysql database.
Cyrus IMAP
The Cyrus IMAP is developed and maintained by Carnegie Mellon University. Unlike the WU-IMAPd Cyrus is using its own method to store the users mail. The data is stored in a database, this makes Cyrus so performant. Especially with lots of users and/or lot of big emails, there is nothing such fast as the Cyrus IMAP-server. Another very important feature is, you don’t need a local Un*x user for each account. All users are authenticated by the IMAP-Server. This makes it a great solution for really huge base of users.
User administration is done by special IMAP-commands. This allows you to eighter use the commandline interface, or use one of the available Webinterfaces. This Method is much more secure than a Webinterface to /etc/passwd! Since CMU changed the license policy for Cyrus, this software is going to be used by much more users
Web-cyradm is the Webinterface that allows you to perform the administrative tasks to your mailsystem This Screenshot shows the domain-administration part of Web-cyradm.
Web-cyradm is written in PHP, which is often installed on webservers. Time to set up Web-cyradm takes just a few minutes. At the time being, Web-cyradm does not support different roles for its users. So you cannot use it as a frontend for your
