In this tutorial, I will guide you through the necessary steps to install an ipw3945 wireless adapter on a CentOS / RHEL based distribution. It is written for CentOS 5.2. However, it might work on other CentOS 5.x based distributions as well.

IP aliasing is the process of adding more than one IP address to a network interface. This is useful for virtual hosting of Web or ftp servers. This tuorial explains how to assign two more IP address to a single network interface under FreeBSD operating system.

If you hail from one of the hot beds of high tech - Silicon Valley, say, or (in my case) the Route 128/495 area of Massachusetts, you've doubtless heard the phrase "serial entrepreneur." What those words describe is someone who has started several companies, and the phrase, when used, is invariably regarded as a compliment. These days, if such a serial entrepreneur has some major successes under her belt, that makes her one of the elite of the high tech nobility - someone with the golden touch, that can turn ideas into huge returns for founders and investors alike. But should this really be a compliment?

Ubuntu fans rejoice, the latest release is upon us in the form of version 8.10, Intrepid Ibex. But can't you just run a software update in Hardy Heron? I'll tell you what's different down to the package level between an upgraded Hardy installation and a fresh Intrepid installation so you can evaluate for yourself.

Ever wondered what takes your Linux box so long to boot up? You can see for certain with the Bootchart package. Bootchart logs the entire startup process and produces a clean, graphical representation of its results suitable for everything from troubleshooting to good old-fashioned bragging rights. Bootchart is a common utility, so check your distribution's package management system first to see if it is available. If not, the Bootchart download page provides links to the official packages for Debian, Ubuntu, Gentoo, SUSE, and Mandriva. You can also download source code in an RPM or tarball from bootchart.org. The package contains installation and uninstallation scripts and compilation instructions.

BOSTON, Mass — November 3, 2008 — The GNOME Foundation announced today that Motorola and Google are joining the GNOME advisory board and sponsoring the GNOME Foundation.

Google introduced the beta version of its open source Chrome browser nearly two months ago, and issued its third update to the beta yesterday. (The update pushes to you automatically if you're running Chrome.) Although there are signs that the very early popularity of this browser has calmed down somewhat, it's still generating a lot of buzz, Google has confirmed that many extensions are coming for it, and I expect to see it in a mobile version very soon. If you're running Chrome, here are seven tips for customizing and getting the most out of it.

It's time to start fixing telecom, even as we're moving past it. If ideas are weather systems, that's the squall I'll bring to the Telco 2.0 Executive Brainstorm in London tomorrow and Wednesday. This is my first time at one (it's the fifth in their series), and I'm looking forward to it. Here's the agenda. I like what they're thinking (here's the Telco 2.0 Manifesto) the way they think it (such as this on "two-sided markets"), and where we might run with it. By "we" I mean the Linux, open source and free software communities. Some of which live inside telcos and cablecos.

A more complicated and feature-rich version of last week's localtv script. For this week's Monday Linux/Unix bash shell script, we're following up on what turned out to be a fairly popular script from last week that made it so you could get your local tv listings from the command line with bash.

The news that Wikipedia was in the process of switching away from Red Hat and Fedora—and to Ubuntu—has stirred up some Fedora folks. The relatively short, 13 month support cycle for Fedora releases was fingered as a major part of the problem in a gigantic thread on the fedora-devel mailing list. Some would like to see Fedora be supported for longer, so that it could be used in production environments, but that is a fundamental misunderstanding of what Fedora has set out to do. The idea of supporting Fedora beyond the standard "two releases plus one month", which should generally yield 13 months, is not new. It was, after all, the idea behind the Fedora Legacy project. Unfortunately, Fedora Legacy ceased operations at the end of 2006, largely due to a lack of interested package maintainers. So, calls for a "long term support" (LTS) version of Fedora are met with a fair amount of skepticism.

News from the weekend: Theo de Raadt of the OpenBSD project announced the version 4.4 of the free OpenBSD operating system, including a new song.

The New York Times is running an interesting piece from IDG News on how administrators and IT chiefs for higher educational institutions are at odds over whether it makes sense to deploy open source software instead of proprietary products. The flap went on this week at the Educause conference in Florida. Within the argument that's going on, a number of surprising fallacies about open source are apparently cropping up. Here are the details.

In this week's Roundup we have a slew of articles about Ubuntu and Canonical, Linus learns to take personally, our own Sander Marechal reports on T-DOSE 2008, PC makers move closer to a post-Windows world and Carla Schroder asks if Linux does enough for small business.

Emulation refers to the duplication of functions of one system using a different system. Specifically, an emulator is software specifically written to emulate aspects of the original console or computer, primarily the CPU, I/O and memory system.

All last week, Microsoft was trying desperately to shift the spotlight from Vista, the OS that has become a major liability for the software giant. To that end, Microsoft made a flurry of announcements including Azure, the newly announced cloud platform, the Windows 7 Alpha and a preliminary view of the web-based version of Microsoft Office.

My former colleague, Joe Wilcox, observes that he doesn't think it's a big deal that Microsoft handed out laptops to bloggers, analysts and reviewers loaded with the Windows 7 alpha. He adds that "All week, I have watched for someone to raise a fuss and hoped that no one would." Wilcox then added that, last time around when Microsoft did this with Vista, that Steven J. Vaughan-Nichols "joined the chorus of critics calling the laptops bribes," while he had defended Microsoft's practice.

South African Internet billionaire Mark Shuttleworth has enough cash to pump into his software company, Canonical, saying he is being careful with his pennies but is willing to continue supporting a good investment. Shuttleworth founded Canonical in 2004 to develop free software for companies and private users around the world.

Yesterday evening, while I was at home in Freising, my brother called. He had some problems installing Ubuntu on our aunt’s computer, and asked for help. In the end, it was a success story. But it’s a quite lengthy one; it actually started years ago. Read on for more details…

Greg Kroah-Hartman is a longtime developer of the Linux kernel, known for his work maintaining USB drivers as well as for packaging the SUSE kernel at Novell. O'Reilly Media recently interviewed Greg about his claim that the Linux kernel now supports more devices than any other operating system ever has, as well as why binary-only drivers are illegal, and how the kernel development process works.
