Broad variety of support and consulting services for their distributed open source solutions. Nevertheless, these open source projects do not include an inherent warranty or legal liability. Due to its benefits, the dual license approach is becoming increasingly popular. Several well- known companies such as MySQL, Sun, and Ghostscript are using this licensing model. Small and medium-sized software companies can use this approach as a business model to gain and expand new customer bases.

Borland Delphi is known to be a great environment for the development of stand-alone and client-server applications on the Microsoft Windows platform. Its virtues range from full OOP support to visual development, in a unique combination of power and ease. However, the new frontier of development is now Internet programming. What has Delphi got to offer in this new context? Which are the features you can rely upon to build great Internet applications with Delphi? That’s what this paper intends to reveal. We’ll see that Delphi can be used:
• For direct socket and TCP/IP programming;
• In conjunction with third-party components that implement the most common Internet protocols, on the client or the server side;
• To produce HTML pages on the server side, with the WebBroker and Internet Express architectures;
• As well as to work with Microsoft’s core technologies, including MTS, COM, ASP, and ActiveX.

Adaptive algorithms are an important technique to achieve portable high performance. They choose among solution methods and optimizations according to expected performance on a particular machine. Grid environments make the adaptation problem harder, because the optimal decision may change across runs and even during runtime. Therefore, the performance model used by an adaptive algorithm must be able to change decisions without high overhead. In this paper, we present work that is modifying previous research into rapid performance modeling to support adaptive grid applications through sampling and high granularity modeling. We also outline preliminary results that show the ability to predict differences in performance among algorithms in the same program.

DOT NET is one of the key products that enable application development under the new vision. However, DOT NET is not quite backward compatible with prior versions like visual basic version 6. This makes migration a serious issue. Converting existing source code to DOT NET architecture is not just a matter of loading it to the new version. DOT NET has its built-in migration tool, which performs the vital task of converting the source code syntax. But that’s just half of the work done. But before the converted code is actually compiled, the developer needs to enable it to smoothly fix lot of issues to fit into DOT NET architecture. In present efforts to find out solutions to these migration issues, a re-engineering Migration Model for Legacy Source Code (MMLC) has been proposed in this study. Proposed model has been further validated using a in-house project at one of the leading software development organisation. It is envisaged from the experimental try-out that the model would help the developer community to easily convert their legacy source code to DOT NET framework.

Virtual Observatory (VO) is a collection of interoperating data archives and software tools. Taking advantages of the latest information technologies, it aims to provide a data-intensively online research environment for astronomers all around the world. A large number of high-qualified astronomical software packages and libraries are powerful and easy of use, and have been widely used by astronomers for many years. Integrating those toolkits into the VO system is a necessary and important task for the VO developers.

E-commerce, pay-per-use online services, user-authentication and tracking for e-learning, online gaming, contests… What do all of these applications have in common? The need for secure transfer of encrypted data between client workstations and server applications. According to a study by Gartner Consulting, the growing concern for Internet security parallels the evolution of e-business. In the earliest days of Internet development, the emphasis was on distributing content over the web and making it available to anyone. Now, as the Internet matures, clients are more concerned with ensuring that their assets, both monetary and intellectual, are protected from those who may commit fraud or abuse them. This is why more and more developers have been looking for security solutions.

Beginning with version 2.5 (currently in Preview Edition) building Silverlight 2 applications, and especially assembling the User Interface components such as items from the toolbox, and layout controls, is easier than ever. A Note on This Tutorial. The history of the material for this tutorial is that Scott Guthrie wrote a terrific introduction to this material at the end of February, which he gave me permission to turn into a series of videos, currently (or soon to be) available on Silverlight.NET. This tutorial completes the circle by building on the videos and integrating the material into the Silverlight Tutorial series. The project we’re setting out to build is very similar to the Silverlight chat service built by ScottGu, and is shown in Figure 5-1
