My previous article discussed a set of dynamic menus based upon no more than one, simple web page template, a few appropriate text files and absolutely minimal php code. There is a caveat, I dodged my responsibilities, i.e. I showed no effort to catch failures and errors. This was due to my initial code being flawed, hence, the first article was able to stress the core simplicity of the endeavor. Now, however, I attend to more serious business of both noticing failures and notifying those responsible.

With openSUSE 11.0 just a few days away, it’s time to look at one of the stars of the show: KDE. In openSUSE 11.0, you get two KDEs for the price of one. Here we’ll take a look at what’s coming in KDE, and talk to one of openSUSE’s KDE contributors, Stephan Binner.

Email: businesses can't stay competitive without it, but the bigger a company is, the more of a headache managing an email server can be. There are plenty of email management tools on the market, but many are expensive or lack easy customization. AtMail recently added an open source option to its product line that offers many of the same features commonly found in other Web mail apps, but for the low, low cost of free.

As the representative for Norway in the recent OOXML ratification process, Steve Pepper has become an outspoken critic of the IEC/ISO process. Pepper is also a passionate advocate of XML, open standards and Topic Maps. Here Pepper, who is in South Africa for the XML in Government workshop, speaks to Tectonic about what happened in Norway, Topic Maps and why open standards are important for governments.

Already announced, the new winner is IBM’s RoadRunner – the first supercomputer to break the ‘mythical’ 1 TFop/s barrier. At a recent benchmark, it achieved 1.026 TFop/s on the Linpack benchmark. The OS is yet to be confirmed, but pretty-much every other IBM computer in the list is running a version of SUSE. I’ll be guessing much the same as you! Assuming the remainder of the list looks a lot like the previous list (November 2007), running second and third, we find a couple of IBM Blue Gene systems, then SGI and Hewlett Packard get a look in.

Catch all of your podcasts in style with gPodder, a Python application designed to retrieve and organize your podcasts for easy playback. gPodder can handle both RSS 2.0 and Atom podcast feeds. As soon as you add episodes to the podcatcher, the application can download them using a few different protocols, including authenticated HTTP (for feeds that require a password) and BitTorrent. BitTorrent is especially nice for popular podcasts that have a lot of subscribers and large episodes, because you can use it to download from multiple sources, called seeds, and speed up your downloads.

As you may have noticed, Firefox 3 is released today. Excited by this prospect, the first thing I did when I got up was to rush to my computer to download it (yes, pathetic, I know). And what do I find? That only Firefox 2 is on offer. I go to the main Download Day 2008 site, and for all its flash/Flash zoomable graphics, I can't find any information about exactly when Firefox 3 will be publicly available, which seems crazy: the one thing this site should be doing is making it easy for as many people as possible to download Firefox 3.

Mozilla Mac developer Josh Aas has written a weblog post discussing some of the under-the-hood improvements specific to the Mac OS X version of Mozilla Firefox 3. Josh describes how Firefox 3 has largely switched from Apple's legacy Carbon API (initially created to make it easier for developers to migrate OS 9 applications to OS X) to the more modern Cocoa. He also details how Firefox 3 delivers native-looking Aqua-style form controls in Web pages and explains how this actually has very little to do with the change to Cocoa.

The trash project allows you to interact with your desktop trashcan from the command line. It lets users "undo" deletions made with the trash command in a similar manner to restoring files from the trashcan in a desktop environment. For experienced Linux users, the trash command comes in handy when you want to put a file into the trashcan from the command line. Because trash implements the FreeDesktop.org Trash Specification, it plays nicely with the trashcan offered by the KDE desktop environment. That means you can trash a directory from the command line and see it in your trashcan from Konqueror. Unfortunately, the trash implementation in GNOME 2.20 did not communicate with either KDE 3.5.8 or the trash command.

Novell Monday released updates to its Suse Linux kernel designed to make the operating system more efficient when running on top of VMware environments. The upgrade to the Suse Linux Enterprise kernel lets it take advantage of paravirtualization techniques so it runs more efficiently as a guest operating system. Specifically, Novell has built in support for VMware's Virtual Machine Interface (VMI)."The patch to the kernel provides increased performance and better interoperability," says Carlos Montero-Luque, vice president of product management for open platform solutions at Novell.

One of the arguments I often hear from people who are trying to use linux for the first time is that they are not sure if they can switch back to their original choice of OS (usually windows), if they are not satisfied with their experience with linux. These are usually the people who are not as tech savy or previously had bad experience while trying to install linux which resulted in destroying their windows installation. With each iteration of windows OS Microsoft has made it less friendlier for linux to be installed along with windows.

While the computing giant has no immediate plans to open source DB2, market conditions may make it unavoidable, according to Chris Livesey, IBM's U.K. director of information management software. "We have a light version of the product offered for free, which is a step towards exposing our core (DB2) technology," said Livesey. "Looking at IBM's heritage in contributing to the open source market, we've been particularly keen to lead that market. Open source is an interesting space, as a whole. As the future unfolds, and the economics become clearer, there's going to be more commitment to open source by everybody. We've made good steps towards that."

Wide take-up of the new version would further boost the market share of the browser which is currently used by about 15% of net users. With the release, Firefox developer Mozilla is attempting to set a record for the most downloads over 24 hours. "It's a global effort to make history," said Paul Kim, head of marketing at Mozilla.

"I regularly run and post various benchmarks comparing POHMELFS, NFS, XFS and Ext4, [the] main goal of POHMELFS at this stage is to be essentially as fast as [the] underlying local filesystem. And it is..." explained Evgeniy Polyakov, suggesting that the POHMELFS networking filesystem performs 10% to 300% faster than NFS, depending on the file operation. In particular, he noted that it still suffers from random reads, an area that he's currently focused on fixing.

As free software projects balloon in size, many struggle to create and maintain a sense of community. One of the projects that has been most successful in its community-building efforts is the content management system Joomla! In the last couple of years, its Joomla!Days have been held around the world. A particular case in point is this past weekend's Vancouver Joomla!Day, whose organization and use of social networking to expand the scope of the event make it a case study in modern community-building.

Virtual machines are virtually taking over the world. By itself a virtual machine is just a container that describes various resources such as memory, disk space, processor, and network card, and allocates them from a physical machine. As with a physical machine, it's the software bits (the operating system and applications) that make a virtual machine usable. When you mix a virtual machine with real software you get a virtual appliance. Some complete Linux distributions as well as specialized apps are available as virtual appliances. Thanks to the ease in packaging one, there's no shortage of virtual appliances around, if you know where to look.

Linux-based guitar effects processors haven't exactly been flourishing recently. Until recently, the guitar FX processors page at linux-sound.org listed twelve projects, of which the most recent maintenance date is 2006. Clearly, not a flourishing domain for Linux audio developers. Not that Linux lacks realtime effects processing capabilities: Pd can be pressed into any audio service imaginable, the JACK Rack can be configured for LADSPA-based effects, but they are not organized and optimized specifically for guitarists. However, a thirteenth entry has joined the collection at linux-sound.org, and this entry is most definitely organized, optimized, and intended for guitarists.

And to think Microsoft used to be popular with the developer crowd...Not anymore. A recent report from Evans Data shows fewer than one in 10 software developers writing applications for Windows Vista this year. Eight percent. This is perhaps made even worse by the corresponding data that shows 49 percent of developers writing applications for Windows XP. Such appreciation for history is not likely to warm the cockles of Microsoft's heart, especially when Linux is getting lots of love from developers (13 percent writing apps for it this year and 15.5 percent in 2009). The Mac? I don't have any equivalent data via Evans Data. But the Mac OS has rocketed by 380 percent as a targeted development platform, Evans Data told Computerworld.

The Fedora Project is the free community release from enterprise Linux giant Red Hat. It's a testing ground really for a lot of new ideas which usually end up in the company's commercial Red Hat Enterprise products. I've used Fedora in the past on and off but for some reason it's never quite stuck with me. I've often found it buggy and a little too unstable due to it's experimental nature.

SiteBar is a Web browser bookmark synchronization solution. One feature that sets SiteBar apart from many others is the ability to set up your own bookmark server, which keeps the whole system under your control. You can also use SiteBar through a third-party server that offers membership levels ranging from a free, ad-supported "basic" level up to an "admin" level that costs 9.99 Euros (about $15.50) per month. While SiteBar is useful for individuals, it is even more useful for corporate or other groups because it allows you to have many trees of bookmarks and have a project group collectively modify bookmarks for their project. (NOTE: Other bookmark synchronization solutions have been covered recently on linux.com.)
