Guvnor is the business rules management system in Drools 5. When you deploy it out of the box, you get an unsecured web application that stores data in Jackrabbit’s embedded Derby database. This two-part article explains how to tune Guvnor deployed on JBoss Application Server 4.2.3. (If you missed the first half of the series, catch up in our archives.)This means that we will use the container’s configuration files and security infrastructure. This installment covers enabling password validation based on an OpenLDAP server, moving from the default data repository, and enabling SSL for better security.

Sun Microsystems has open sourced its Java toolkit for building mobile applications just as the role Java plays on handsets comes into question. The company has released the Light-Weight UI Toolkit (LWUIT) under a GPLv2 license with a classpath exception - for binary linking with an application - as an incubator project to Java.net. Fixes to LWUIT from Sun will be posted to the repository.

The following is a follow-up to the Slackware WPA-PSK HOWTO, describing the way to configure the HP 530 laptop, Slackware 12.1 OS and a Lantech wireless access-point router using WPA2 encryption method. It might be however tuned up to match other router/distro combinations.

Open source is about a lot more than just Linux, though open source software vendors can learn a lot from the success of Linux. That's where open source database vendor EnterpriseDB is headed with its new CEO Ed Boyajian, who was recruited out of Linux leader Red Hat in June. In an interview with InternetNews.com, Boyajian explained how the lessons learned from Red Hat about growing an open source business can be used to grow an open source database business as well.

This video is fromnuvalo who writes: "This is the latest kernel from Wii-Linux, which supports USB, Bluetooth, etc. This video shows how it boots T2 SDE for PowerPC, with its X server and the login. The colors are messed up as the X server writes its colors in RGB format, and the Wii frame buffer only supports yuv2. Anyway, it is possible to run an X server without too much effort."

If you have a process ID but aren't sure whether it's valid, you can use the most unlikely of candidates to test it: the kill command. If you don't see any reference to this on the kill(1) man page, check the info pages. The man/info page states that signal 0 is special and that the exit code from kill tells whether a signal could be sent to the specified process (or processes).

When I came across the oddly named SliTaz I really didn’t know what to expect. Yet another predictable fork of some better known distro which would blaze briefly in the free software firmament, burn out and fall to Earth, spent? Boy, was I ever wrong. If you want to know why Switzerland may be about to become better known for more than chocolate and Cuckoo clocks, read on and be prepared to be impressed and delighted by a live distro of exceptional speed and size.

Linus Torvalds is a Finnish born software engineer best known for two things: kick starting the development of the Linux kernel, and owning the Linux trademark. Actually, make that three things. Torvalds has recently become very well known for speaking his mind...

From the "who needs a pre-load when you're embedded" files: Dude - if you're getting a Dell then you're getting Linux. No you don't have to order one of those fancy Ubuntu pre-load deals. This is an embedded Linux that will be available on a whole bunch of new Dell Latitude laptops in a feature called Latitude ON.

A glitch in VMware's most recent update had customers scrambling this week. A problem caused by a bug from the beta version of the software that engineers failed to remove or deactivate left VMware users unable to power on virtual machines running the hypervisor software. The bug, also known as a"time bomb," is code that developers insert in beta software to push users to upgrade to an application's final version.

Sure, it would be nice for Oracle and SAP to endorse Canonical and Ubuntu. But it won't happen anytime soon. And that’s not a problem -- not even a small one. Here’s why.

I was already mourning the destruction of my Saturday, thanks to some blown deadlines, and was resigned to spending at least part of the day working. Then I made a fatal error: I read my email. There were two messages from readers that said, in essence, another article about RAID 5 was about as interesting as yet another fawning review of Ubuntu Retching Rabbit or Pooping Penguin or whatever the newest coolest release is, and RAID 5 has some serious flaws anyway, and if I really wanted to be hip and helpful I would write about RAID 10.

My advice is to avoid dual-booting, and especially triple-booting (or even more than that). If you set up a box to dual-boot with two Linux distros, Linux and Windows, or even a BSD (OpenBSD, NetBSD, FreeBSD) and Linux, and you leave it alone, you'll probably be OK. But me, I'm testing things all the time, and lately I've been playing around with triple-booting on my Gateway Solo 1450 laptop. I've done this a lot, and I generally know how to do it so I don't hose one partition or another. But I slightly hosed something on the laptop last night.

Lenny (aka 'testing') appears poised to displace Etch as the popular Linux distribution's "stable" branch next month. To see how Lenny was coming along, I loaded the latest preview (beta 2) of its KDE system image onto an available Thinkpad, and took it for a spin.

Despite all its advances, GNU/Linux remains weak in its support for proprietary audio and video codecs. Because these codecs are often encumbered by patents, distributions must choose either to include support of questionable legality or else exclude it altogether. In the middle of this controversy sits Fluendo, a Catalan company of about 50 employees that is a main contributor to projects like GStreamer, and supports open formats, but also offers licensed, proprietary codecs such as Windows Media Video and MPEG4. While many would argue that this dual position is necessary, it's one that sometimes creates an unasy balance for the company, says Muriel Moscardini, Fluendo's sale director.

A federal appeals court has struck down a lower court ruling that found that open source copyrights may not be legally enforceable if they're licensed under terms that are "intentionally broad." Ruling on an appeal brought by software developer Robert Jacobsen, the U.S. Court of Appeals for the Federal Circuit said Wednesday that open source users that do not comply with the software's strict licensing terms can, in fact, be sued for copyright infringement -- even if the software is free.

Open source developers now have newly clarified protection, thanks to an appeals court ruling over the validity of their licenses. A judge with U.S. Court of Appeals for the Federal Circuit ruled Wednesday that programmers who"engage in open source licensing" and copyright their work do"have the right to control the modification and distribution" of their products.

Almost three years ago, developerWorks published "Using the Ruby Development Tools plug-in for Eclipse," which introduced some of the features found in the Ruby Development Tools (RDT) plug-in for Eclipse. Current at the time was V0.5. We revisit that tool in this article. Today, RDT is called Aptana RadRails and is available as a plug-in for Aptana Studio or Eclipse. This article introduces some of the plug-in's new features.

Have you ever wanted to create an installer program on a Linux system, but didn’t want all the hassle of an actual install builder? I have. So I’m going to show you how you can create such an installer with very little hassle. I can’t actually claim credit for this method though; I actually got the idea from Sun’s JDK installer for the Linux platform. You download a “.bin” file, change the file mode so that it is executable and then run it. It displays the end user license agreement, gets some feedback and then goes about installing Java for you. Well, if you open that .bin file up in a text editor (say vi) you’ll see that it’s nothing more than a shell script with a binary chunked onto the end. Thus my plans for world domination were born…

Previously, we've interviewed the lead-developers of Arch and Gobo Linux. Two distributions for the more advanced users out there. This time, we're going in the complete opposite direction to understand more about a user friendly Linux-distribution: Ubuntu.
