This paper discusses some aspects of developing games for Windows Mobile/PocketPC devices using the .NET Compact Framework and C#.NET. Ten guidelines are presented for beginners in this area to learn and get going quickly!Writing portable J2ME Applications
The Palm Phone Library is an interface to phone hardware. Its usage is increasingly gaining importance as developers are developing many applications involving the use of Phone APIs. It is widely used in the organizations mainly responsible for developing applications involving phone feature's usage. Examples include Phone call recording, Black list (used to ignore a particular caller), Caller identification, Customized ringtones, Conferencing, etc.Introduction to gaming using J2ME
Handsets are numerous in the cellphones market, and new ones enter every day. These handsets vary on several parameters like screen size, heap size, maximum application size, apart from special-key layout and form factors. It is possible to design and write J2ME applications in a manner that reduces the effort in porting across handsets. This thought-provoking article discusses possible approaches.Hibernate vs JDBC
Game programming is exciting work, just as gaming is exciting play! This article discusses beginner steps in writing games using Sun's J2ME programming technologies. J2ME is a dedicated version of the normal J2SE, designed specifically for device/cell-phone platforms and their inherent constraints. Key small-device usage and performance considerations to be kept in mind and the first few steps into J2ME programming are discussed in this article.Struts Tiles vs JSP Include
Traditionally, JDBC has been the data access model of choice for most Java developers. The introduction of Hibernate brings Object-Relational Mapping (ORM) as a data storage/access solution. Hibernate is quite naturally suited to the Object-Oriented way of thinking, and to a pure Object-Oriented language such as Java. In this article we discuss the merits and demerits of each approach. Hibernate in general has advantages, but in specific situations the use of JDBC may be advisable.Macromedia Flash and VB: A potent combination
The separation of design and programming has been a priority for web application development environments. Designers and programmers are different sets of people, and each would like to make changes independently; this separation allows such workflows to exist. Second-generation Java web development achieved this using JSP and JSP Include files. The current generation of Struts MVC frameworks brings with it Struts Tiles, an advanced method of achieving UI-code or design-program separation. In this article, we discuss the advantages we see in the Struts Tiles approach, and list some demerits as well.Developing Web Services using JAX-RPC
This article focuses on an often-neglected but all-important aspect of any software application – the user interface. For years, desktop applications have had boring gray rectangular windows, buttons etc. Animation, multi-media, visual effects and custom elements were possible, but required large amount of custom programming. Even making a non-rectangular button would need good C++ skills. The web and its use of Flash change the equation. Web-based applications look far more attractive and user-friendly than comparable desktop application, but are easy to develop with Flash. In this article, we present ideas for using Flash inside VB applications, thus injecting new life into desktop software products.
Macromedia supports Mindfire's approach towards VB-Flash integration, and this article has been published by Macromedia here.Testing: Overview of Checklist-driven Testing (Checklists 101)

We describe the architecture and process used to implement a Web Services wrapper layer over an existing RMI-enabled Java application.Testing: Creating checklists (Checklists 201)
Checklist-driven QA testing can encapsulate the cumulative experience and knowledge of teams, raising productivity and coverage significantly in test efforts. This paper discusses about the various advantages and disadvantages related to checklist-driven testing. While identifying problem areas in checklists, it also intends to supply work-around to attack these problems.Testing: Organizing checklists (Checklists 301)
This paper propels the goodness of custom-made checklists and aims to help test organizations build their own checklists. Creation and selection of items for a checklist can be the make-or-break of a checklist strategy.Migrating from Classic ASP to ASP .NET
When Test Organizations plan serious implementation of checklist driven testing, systematic approach to deal with these rapidly growing custom checklists becomes a critical factor. It is not only difficult to manage growing number of checklists, but also successful implementation becomes questionable. This document describes how checklists can be further classified according to their usage and hence be organized.
