Ultimate++ 602 has been released. Ultimate++ is a C++ platform. U++ competes with popular scripting languages while preserving C/C++ runtime characteristics. New features of the 602 release include a new report package, otimization of C++ refactoring and assistance (Assist++), and improvements in project organization and building.

Potix has released ZK 1.0, the XUL-Java-Ajax-Beanshell based web application framework. The framework aims to simplify developing Ajax based web development by minimizing configuration and lowering developer skill requirements. A live demo is available.

"Perl for zOS is a statically-linked, pre-compiled port of the Perl (Version 5.8.7) scripting language to the z/OS UNIX platform with all known defects resolved. This new porti of Perl 5.8.7 provides a pre-built version of Perl with a dedicated support team to address new problems that may arise."

"This website will provide you with lessons and quality material to learn basics of C language programming in just a few days. All you have to do read trough my lessons. You will notice I'm putting new lessons up every day or two. It would be practical if you had Visual Studio installed on your computer and used it parallel to these lessons, but it isn't neccessary."

Conary is a distributed software management system for Linux distributions. It replaces traditional package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. It enables sets of distributed and loosely connected repositories to define the components which are installed on a Linux system. Version 1.0 was released a few days ago, and a maintanance version 1.0.2 was released today.

"Valgrind is a CPU simulator which is used by KDE and many other projects to profile and debug our programmes. In the interview below Valgrind author Julian Seward talks to KDE Dot News about why he developed Valgrind, how you can use it and, most importantly, where the name comes from."

This Eclipse tutorial gives you a high-level overview of how to use CruiseControl, Luntbuild, and Anthill with Eclipse. Another tutorial shows you how the Eclipse Perl Integration (EPIC) plug-in for Eclipse can help you test Perl applications. One is a traditional Perl debugger, the other tests Perl regular expressions.

Should you make your C++ classes more intelligent or centralize the intelligence and use dumbed-down surrounding classes? The natural world tends to prefer a pass-the-parcel style of distributed intelligence, which reduces single points of failure and potentially leads to more stable systems. In this article, Stephen Morris shows you how to raise the IQ of your classes while simultaneously allowing other (possibly) more-qualified classes to handle specific problems. The chain of responsibility pattern provides an elegant model for facilitating this behavior.

"Today Borland announced plans to seek a buyer for our IDE product lines that include Delphi, C++Builder, C#Builder, JBuilder (and Peloton), InterBase, JDataStore, nDataStore, Kylix, and our older Borland and Turbo language products and tools. The goal is to create a standalone business focused on advancing individual developer productivity using the people inside Borland who are focused on the success of these award winning products."

"I've always assumed that ifup and ifdown were conditional commands that performed their assigned duties only if the interface device in question was up or down, as the command might be. I was dead wrong. I blame my mistake on being a programmer, rather than being stupid, but it's simply too close to call. The if in ifup, ifdown, and ifstatus is not a programmer's if - it's an abbreviation for interface. On the off chance that I'm not the only one who has misunderstood these commands because of their rather iffy names, here's what they really do and how they are used."

NetBeans 5.0 has been released. "NetBeans IDE 5.0 introduces comprehensive support for developing IDE modules and rich client applications based on the NetBeans platform, the new intuitive GUI builder Matisse, new and redesigned CVS support, Sun Application Server 8.2, Weblogic9 and JBoss 4 support, and a lot of editor enhancements."

"R is a rich statistical environment, released as free software, which includes a programming language, an interactive shell, and extensive graphing capabilities. This installment discusses creating reusable and modular components for R development. This article follows up two prior installments and looks at the object-orientation in R along with some additional general programming concepts in R."

This article goes into the motivation and architecture for DTrace -- and describes some of the problems that remain to be solved in system observability. The article also includes a short case-study on using DTrace to find a real problem -- a problem that was ultimately due to some seriously fugly code in a monitoring app.

For years computer interfaces have been held back by two dimensions. The power and flexibility of three dimensional interfaces have remained the stuff of science fiction movies, video games and very custom high-end applications. Aoren Software now brings that power to everyday applications and operating systems through a window server and framework technology called Vision. Vision was designed from the ground up to break away from old paradigms and provide the interface needs of the next generation. Application developers can get their hands on the technology with the developer preview release and start creating programs that have previously resided only in the imagination.
