Following the recent releases of Groovy 1.5.7 and 1.6-beta-2 I'm proud to announce the release of JideBuilder 2.0.

At SpringSource, we had a clear vision for our recently announced maintenance policy: balancing the needs of the open source community with those of enterprise users and the creators of Spring, for the benefit of all. However, we didn’t get the balance quite right first time, and it’s time for some refactoring.

Introducing Geode, an experimental add-on to explore geolocation in Firefox 3 ahead of the implementation of geolocation in a future product release. Geode provides an early implementation of the W3C Geolocation specification so that developers can begin experimenting with enabling location-aware experiences using Firefox 3 today, and users can tell us what they think of the experience it provides. It includes a single experimental geolocation service provider so that any computer with WiFi can get accurate positioning data.

In this conversation Microsoft Technical Fellow and Chief Architect of C# Anders Hejlsberg sits down with programming language design legend and computer scientist Guy Steele (creator of Scheme and expert in several languages ranging from LISP to Java).

If you are here, you are no doubt aware of the new SpringSource maintenance policy. While we respect their decision to value their time and to control the release plan for Spring, we also feel it's important to come together as a community to ensure that there is still a consistent and open production build path for those who are not yet ready to invest in the full services offered by SpringSource.

Terracotta 2.7 went out last week so grab it while it’s hot. Terracotta is the open source Java clustering solution that allows you to cluster your Java heap and scale your Java app.

It’s pretty good advice for how many features you “pack” into a product too. Lay out everything you think your product needs and then cut out half.

The instructions I previously posted to set up Mylyn to work with Google Code do not seem to work with Eclipse 3.4 (Ganymede). Luckily, readers of the previous post have kindly left comments with updated instructions on how to make this tool work again (many thanks to Christopher Barber, RoSt, Sergey Kolos and LI Daobing.)

It is coming out a bit late, but the beta release for the upcoming Fedora 10 release (codenamed Cambridge) is now available. It has been almost two months since the last test release and a lot of work has been accomplished when it comes to the new and exciting innovations found within this Red Hat distribution.

Over the last decade, vector graphics have gone from being a revolutionary format to a standard method of rendering computer images -- so much so that they are standard in the KDE 4 desktops. This popularity is based on the fact that, because they represent images as mathematical equations -- usually in SVG format -- vector graphics open faster, render better on screen, and can be resized more readily than raster graphics, in which an image is created pixel by pixel. Free software includes a number of options for working with vector graphics, including several simple ones: OpenOffice.org's Draw, KOffice's Karbon14, and Inkscape, which is currently the premier vector graphic editor in free software.

The multitenant nature of Software as a Service (SaaS) applications makes security an essential concern. This article introduces a viable and practical approach to securing a multitenant Java application with the open source Spring Security framework combined with Apache Directory Server. The authors present a multitenant example Web application to demonstrate this approach.

The latest release of the IBM JRE for Java SE 6 enhances IBM's class sharing feature first introduced in Version 5. In this article, performance analysts Adam Pilkington and Graham Rawson detail the changes, which include improvements in application startup times and memory utilisation.

The Web is changing along with the weather outside the window, adopting bright autumn-inspired makeovers for seasonal fall sales and special offers. The autumn (or fall) season is primarily associated with: harvest, bright, hot colors, falling leaves.

I’ve just released Mac Widgets for Java version 0.9.2. I’ve added a Heads Up Display (HUD) component and factored out the UI delegate from SourceList so that you can make any JTree look like a Source List.

Chris Harrick, SugarCRM's vice president of corporate and product marketing, discusses the advantages of open source software with Customer Inter@ction Solutions writer David Sims in a Q-and-A interview. They discuss the advantages of open source software as compared with proprietary software.

DesignGridLayout is a simple but powerful Swing LayoutManager. It has several advantages over other LayoutManagers. The main ones are:

Lately I have been writing a number of articles that I would consider to be more critical thinking based, so I thought that it may be interesting to do more of an opinion piece. In the past the article I wrote about bad blog design was successful, so I felt covering web design in general could be helpful as well. It is important to note that in this article I am referring to “web design” as the whole process of creating a site, not just the visual aspect.

One of the pleasures of Linux is that you can try out different distributions to see which one works best for you. You like Ubuntu, but you want to fine tune the desktop engine? OK, try Kubuntu with its KDE desktop then. Some worthwhile distributions, however, don't get as much attention as they deserve. So, here's my list of five great distributions that you might want to try.

I’ve been involved in software development for over a decade, and I can’t tell you how many times I’ve heard this question: Who owns this code? Generally, if someone has to ask, it’s already a bad sign, but the real bad sign is what comes next. “Oh, Bob used to own it, but he left the company, and then it was Kumar, but he transferred over to the other team, now I guess Sue could probably answer questions about it,” but nobody owns it.

If you develop applications using FOSS tools, Workbench is an ideal distro for you. In addition to packing a gamut of development tools, the distro also bundles everyday apps and eye candy, so you can use it on your desktop as well.

This article reviews some of the top open-source version control systems and tools that make setting up a version control system easy.

Trolltech today released Qt 4.4.2 to commercial customers and the open source community. Qt is a cross-platform application framework for desktop and embedded development. Qt 4.4.2 is now available for customer use, evaluation and open source download.

UNIX Internals is a careful, detailed examination of multiple UNIX implementations as they evolved over time, from the perspective of both the academic theorist and the practical kernel developer. What makes this book particularly valuable to the practicing operating systems developer is that the review of each operating systems concept - say, processes and threads - is accompanied by descriptions of specific implementations and their histories - say, threading in Solaris, Mach, and Digital UNIX. Each implementation is then compared on a number of practical levels, including performance, effect on programming interfaces, portability, and long-term maintenance burden - factors that Linux developers care passionately about, but are seldom considered in the academic operating systems literature.

If you've ever asked for help with your Windows computer that won't boot anymore, you've probably been told to "Backup all your data and then reinstall"… but if you can't boot, how can you get to your data? That's the question we'll be answering today.

Designing and building Web sites can be a maze of tasks these days. One tool that can simplify the task is the well-known Firebug extension, which lets you edit and debug HTML, CSS, and JavaScript from within Firefox. As useful as Firebug is on its own, it can actually be extended past its initial setup with additional extensions that can make your work as a developer or designer even easier.
