AJAX or Asynchronous JavaScript and XML seems to be all the rage at the moment. Builder has published a handy primer to get started using AJAX today.

Why waste your time figuring out an algorithm for storing things in a file? And why spend time debugging the code? Let the Boost library do it for you. Saving your data to your own custom-made file formats is easy with the help of the Boost serialization templates. Jeff Cogswell shows you how to save the data and read it back in with ease.

A look at Xen related development and how the implementation works in Fedora Core 4 along with some information on the development plans.

For Linux users, HLA is a strong programming tool that allows them to create powerful programs on a variety of different levels. As HLA becomes more feature-rich, additional applications will be written using HLA under Linux. With HLA and Linux, programmers can develop new and exciting applications anyone can use. Read more.

After downplaying the importance of the emerging Ajax programming model, Microsoft Corp. has decided to jump with booth feet into the Ajax fray. On Tuesday, Microsoft unveiled "Atlas," a Web client framework that is designed to support multiple DHTML controls with JavaScript code.

Many times, you need to know how a certain filesystem looked like at some point in time, and you want to be able to roll back changes that happened to it after that point. While there are multiple solutions to achieve this goal, certainly one of them is to use filesystem snapshots. One of the capabilities of unionfs is to offer the possibility of consistently freezing the status of the filesystem at any given point in time (snapshot). Read more...

Given the rapid rate of technological change, how much can I -- or should I -- teach my students about specific tools? Professor Gary Pollice discusses the virtues of Eclipse technology and explains why he and other instructors at Worcester Polytechnic Institute use it in their courses.

If you are considering moving to .NET development and don't want to break the bank by forking out the money for Visual Studio Builder have a comparison of .NET tools you might want to use. The review includes SharpDevelop, MonoDevelop, XDevelop, Visual SlickEdit, and DreamWeaver.

Recursion is a tool not often used by imperative language developers, because it is thought to be slow and to waste space, but as the author demonstrates, there are several techniques that can be used to minimize or eliminate these problems. He introduces the concept of recursion and tackle recursive programming patterns, examining how they can be used to write provably correct programs.

Analysts of the software industry often point out that the majority of software written in the world is not commercially released, but used in-house. Computerworld has an interesting profile of a well-known company that writes virtually all of its software in-house. It discusses some of the challenges they face, the temptations to use more off-the-shelf software, and some available apps and tools that they do use, that have proved to be useful.

Danny Thorpe is the chief scientist at Borland Software, and was part of the original team that developed Delphi. In this interview Thorpe talks about Delphi, Kylix, and the future of working with the Mono project.

Capacity planning is an important part of the work that Systems Administrators perform on a regular basis. The knowledge about the current utilization levels becomes indispensable to predict when the next hardware upgrade will be needed. Moodss (Modular Object Oriented Dynamic SpreadSheet) is a free tool for collecting data from different systems and making it readily available for analysis.

The second edition of 'Extreme Programming Explained: Embrace Change' explains how and why to use XP. But where to start? XP Explained uses the analogy of entering a swimming pool to describe how organizations get started with XP. There are toe dippers, racing divers, cannonballers, and all manner of variations in between. In this paper Kent Beck and Cynthia Andres characterize these styles.

Quick feedback. More testable code. Finding serious problems early. What's not to like? Michael Kelly pleads the case for unit testing.
