A shift from multi-core power-gobbling monsters toward whisper-quiet systems with single-digit power consumption is rippling through the desktop market. This trend plays right into the hands of a Paris-based company called Linutop, which offers a miniature Linux-based desktop system. The latest version of the machine appeals to customers who are in the market for a machine with green credentials and low maintenance costs. After testing one myself, I found the tiny desktop has a lot going for it.

Linux.com correspondent R. Scott Belford caught up with Open Invention Network CEO Keith Bergelt at the 2008 LinuxWorld Expo and had a pleasant (on-camera) conversation with him.

Cluster computing has played a pivotal role in the way research is conducted in educational environments. Because the amount of available money and hardware varies between university researchers, often it's necessary to find a clustering solution that can work well on a small scale, but also can be expanded into a large computing cluster. To maximize grants, researchers typically ask for an open source solution to meet their needs. Despite the lack of certain desirable features, Rocks clusters are among the best open source solution for building a computing cluster.

NimbleX, a Slackware-based distribution, advertises itself as "the new wave of Linux." However, what is appealing in NimbleX -- its speed and small footprint and the resulting selection of alternative software choices -- will likely strike veteran GNU/Linux users as being very old school. By contrast, its limitations -- too little attention to such aspects as the installer, packaging, and security -- seem all too modern, being reminiscent of other distros intent on commercialization or emulating Windows, even though NimbleX is a community distribution and largely a labor of love for Romanian developer Bogdan Radulescu.

Gmail, Google's popular Web mail application, is already full of useful features all on its own. But Firefox users can further customize Gmail with a variety of add-ons. Some only change the appearance, while others add functionality that makes Gmail more like a personal planner than just a plain old email application. Let's take a look at three Firefox add-ons for Gmail.

This week in our parade through the wide world of the Linux.com forums, what to do with a stolen-then-recovered laptop, how to rescue an Eee PC netbook stuck in an endless boot loop, and how make Likewise Open and /etc/skel play nice together. Plus, competitive bash scripting, unanswered questions, and a world of bad Olympic puns.

We have written about the OpenStreetMap (OSM) project many times, but we have yet to explain how to get started with it as a contributor. Since it is the vacation high season in the Northern Hemisphere and many more people will be hitting the maps, this is the perfect time. You can contribute a lot to the project even if you don't own a Global Positioning System (GPS) device -- or even a compass.

Since the Chinese government began supporting domestic open source communities in 2005, hundreds of thousands of young people in the world's most populous country have become a part of the open source world.

Digital video recorders (DVR) are becoming more and more mainstream. TiVo, in fact, has passed the truest test of any popular technology -- having its name transformed into a verb. MythTV, a free and open source application that lets you turn a computer into a DVR, burst on the scene a few years ago, and has found fans among Linux users. However, with a little effort, it's possible to run MythTV front ends on Windows XP, Windows Vista, Xbox, and even an Apple iPod Classic.

I first heard of gOS when it was chosen to power the $199 Wal-Mart gPC. The third iteration of the OS, gOS 3.0 "Gadgets" Beta, was released last week. It's a great Web-focused desktop, but it doesn't offer much to experienced or current Ubuntu users.

gOS is an interesting Ubuntu GNU/Linux offshoot. We've reviewed it and interviewed gOS founder Daniel Liu. Now, in this video, you can see the distro in action before you decide whether it is something you want to download and play with for yourself. Remember that this video was made with a beta version of gOS Gadgets 3, so some features don't work correctly that will almost certainly be just fine in the final version. That caveat given, here's the video.

With DrasticGrid, you can easily put a MySQL database table or view on a Web page, complete with editing, sorting, and pagination capabilities, and support for adding and deleting records.

The Open Source Census goes way beyond the traditional, too rarely used Linux Counter. It claims to be "the first collaborative, global project to count the number of installations for each open source software package." A lofty (and possibly unobtainable) goal, perhaps, but in this video, shot at LinuxWorld 2008, OpenLogic's Kim Wein explains why OpenLogic, along with more than a dozen other companies and groups, is sponsoring the Open Source Census.

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.

Quantum GIS 0.11.0, released last month, is a free geographic information system (GIS) application released under the GPL that runs on multiple platforms, including Linux. QGIS can read, edit, and export common GIS file formats. After installing it and using it to work with existing data layers available from official data repositories, performing common spatial analysis tasks, and sharing files and data with the commercial GIS products, I found QGIS has the potential to be a viable alternative to proprietary commercial GIS programs from the likes of ESRI and Intergraph/Geomedia.

Firewall Builder (fwbuilder) is a graphical application that can help you to configure IP traffic filtering. It can compile the filtering policy you define into many specifications, including iptables and various languages used by Cisco and Linksys routers. Separating the actual policy you define and the implementation in this way should let you change what hardware is running your firewall without having to redefine your policy for that platform.

Who says you have to give up your must-have Windows applications when you migrate to Linux? If you can't leave some crucial Windows program behind, you can run it using CodeWeavers' latest version of CrossOver Linux.

Pardus is a GNU/Linux distribution funded and developed by the Scientific and Technological Research Council of Turkey. Pardus has its own unique installer, package manager, configuration wizard, and control panel. This originality, and the developers' attention to detail, make Pardus worth a look.

Vyatta offers hardware and open source software for enterprise-level network infrastructure. Vyatta can turn any 32-bit x86 machine with at least one network interface into a network appliance that handles routing, firewall, and VPN tasks. The company released Vyatta Community Edition 4 in April, with improved scalability and feature enhancements. Large enterprises now have a low-cost alternative to proprietary hardware like the Cisco 7200.

Network latency and bandwidth are the two metrics most likely to be of interest when you benchmark a network. Even though most service and product advertising focuses on bandwidth, at times the latency can be a more important metric. Here's a look at three projects that include tools to test your network performance: nepim "network pipemeter," LMbench, and nuttcp.
