Want to learn the Linux computer operating system? If you're an Amelia County high school student, the opportunity is there.
In the first two parts of this series we took a tour of the Soekris 4521 single-board computer and installed the Pyramid Linux operating system. Now it's time to build a good stout iptables firewall.
When you're used to hacking on old PCs it's easy to fall into bad habits, like stuffing all manner of services on border routers and turning them into "Internet gateway/LAN servers" because you have the capacity, and you don't want to clutter up the place with big old PCs dedicated to specialized jobs. But this isn't really the best way to design your network.
Years after the event, I still remember it. Sixth grade had rolled around and my parents, having come to the conclusion that I need to learn to dance, signed me up for ballroom lessons, along with every other student in the local school system.
OpenSolaris isn't a true open-source project, but rather a "facade," because Sun Microsystems doesn't share control of it with outsiders, according to IBM executives.
It would be hard to ignore the zeitgeist growing around virtualization. In less than a decade, the playing field has gone from one company shouting into the wind to a market that had no idea what it was talking about to a packed arena - both in the stands and on the field.
Today, the virtualization vendors are selling not just software to transform one physical box into several (or many) independently operating units, but also applications optimized for virtualization and management tools positioned for virtual environment.
Nearly everyone knows that horrible, sinking realization that something's gone wrong. The file you saved isn't there, or at least it isn't where you thought it was. The machine just rebooted and there's a little dialog box saying that the disk isn't recognized, would you like to initialize it? Most of you know what happens next: you do the one thing that guarantees that the data stays lost. You do something hasty, something stupid. In short, you panic.
Tiger teams, originally a military security-testing concept, are now used to test computer security as well. Forming an attack/defend security exercise is a useful way to test security, as well as train employees. Here's how to organize such an exercise, and some necessary rules to make it successful.
Nstein Technologies, provider of text mining and multilingual information access solutions, announced the launch of 12 annotators, compliant with the open-source Unstructured Information Management Architecture (UIMA) standard developed by IBM.
OpenOffice.org Premium can be downloaded from the SourceForge Web site, but is available only for Windows. A native Mac OS X version of the suite will be previewed in France in September.

Today we'll set up a more complex digital receptionist that answers incoming calls according to holiday and off-time schedules, and as a special bonus create a telemarketer tarpit that diverts unwanted calls into special contexts of their very own.
The BSP will take place on Saturday, 9 Sept. 2006 in the cluster room of my former research lab, the Artificial Intelligence Laboratory in Zurich-Oerlikon. A separate announcement for the second event will follow.
This article introduces Struts, a Model-View-Controller implementation that uses servlets and JavaServer Pages (JSP) technology. Struts can help you control change in your Web project and promote specialization. Even if you never implement a system with Struts, you may get some ideas for your future servlets and JSP page implementation.
It is true that wget is ultimate command line downloader. But when it comes to download acceleration wget fails to deliver the download speed. Linux and UNIX oses can use Axel and prozilla programs. These programs opens more than one HTTP/FTP connection per download and each connection transfer its own, separate, part of the file. It may sound weird, but it works very well in practice. For example, some FTP sites limit the speed of each connection; therefore opening more than one connection at a time multiplies the allowable bandwidth.
The OpenDocument Fellowship is tendering a conversion toolkit from HTML+CSS files into OpenDocument Text.
Software doesn't just appear on the shelves by magic. That program shrink-wrapped inside the box along with the indecipherable manual and 12-paragraph disclaimer notice actually came to you by way of an elaborate path, through the most rigid quality control on the planet. Here, shared for the first time with the general public, are the inside details of the program development cycle.

The Danish debates about open standards continues. Over at Ingeniøren, we are covering the development extensively and continuously, but only in Danish. On Monday, we brought a story with roughly the same title as this entry’s title. The story is about the so-called Rambøll-report, which is a report about the costs related to switching to open standards for document formats in the Danish government. The report is made by Rambøll Management, a Danish consultancy, on behalf of The Danish Open Source Business Association (OSL).
CompuLab has introduced a 2.7 x 2.3-inch computer-on-module (COM) based on a 500MHz AMD Geode LX800 processor. In addition to its x86-compatible processor, the CM-iGLX integrates display, disk, USB, and networking controllers, and boasts fanless operation over an extended temperature range.
The Debian project has updated the stable distribution Debian GNU/Linux 3.1. This update mainly adds security updates to the stable release, along with a few corrections to serious problems. Those who frequently update from security.debian.org won't have to update many packages and most updates from security.debian.org are included in this update.
NetBSD runs on more hardware platforms than any other UNIX derivative due to smart design decisions and a commitment to portable code. For porting an operating system to a proprietary embedded system or looking for stability and compatibility across hardware platforms in the lab, the smart choice is NetBSD
. In addition, learn why its open license is a compelling alternative to Linux and the GNU Public License.
According to a report released last week by The 451 Group, enterprise users aren't as concerned with a stack provider's ability to provide exclusive support for their products as previously thought. The report, "Stack and Deliver," suggests that stack providers -- companies that offer pre-assembled sets (stacks) of commonly used open source software components and services -- should focus more on the quality of support, not just its delivery method.
