This article describes how to install and configure Nginx to accelerate an Apache server based on RHEL 5.2.

Doug Moran, one of Pentaho's founders, offers a fascinating description of how the company was created in part by bringing on board the chief architects of several other open source projects, offers not one but two explanations of the Pentaho name, and says more on the recent adoption of the GNU GPLv2 for its Business Intelligence platform.

In the two previous articles my focus was on the catching an error where it was impossible to generate any valid menu, even the many of the meta tags in the head(er) section were unknown. The next possible error of significance to be examined here is the case where the menu should exist, but the file that contains the appropriate listing and links is absent. Again it is impossible to generate the menu, but for a differing underlying reason. Moreover, the severity is no less than the first set, it is just found later in the process.

So far, I have come away with several interesting realizations, the more important of which are these: That people are more ready and willing to distance themselves from Microsoft than I had originally anticipated, and translating that into getting them to use Free/Open Source Software will have a huge effect on the digital landscape in this area and elsewhere â?? and let me emphasize the elsewhere because if it can happen here, it can happen elsewhere. So whoâ??s ready to make history in their community?

In this context, a one-liner is a set of commands normally joined through a pipe (|). When joined by a pipe, the command on the left passes its output to the command on the right. Simple or complex, you can get useful results from a single line at the bash command prompt.

A recent thread on the lkml discussed a blog entry stating that minimal ZFS support for GRUB was available under the GPL license, "we could now use that code to implement support for ZFS in the Linux kernel." Alan Cox explained, "no we can't. The GPL ZFS bits don't include the various methods that would violate the patent so there is no grant. I've several times asked Sun to simply give permission and they don't even answer. I can only read the Sun motivation one way - they want to look open but know that ZFS is about the only thing that might save Solaris as a product in the data centre so are not truly prepared to let Linus use it." H. Peter Anvin added, "from what I can see, it is an absolutely-minimal read only implementation."

When you buy a new PC today, unless you hunt down a Linux system or you buy a Mac, you’re pretty much stuck with Vista. Sad, but true. So, when I had to get a new PC in a hurry, after one of my PCs went to the big bit-ranch in the sky with a fried motherboard, the one I bought, a Dell Inspiron 530S from my local Best Buy came pre-infected with Vista Home Premium. Big deal. It took me less than an hour to install Linux Mint 5 Elyssa R1 on it.

Canonical has been in talks with Sun Microsystems and SpringSource to support one of their open source Java application server stacks in the Ubuntu core, to increase Ubuntu's enterprise adoption. Canonical told The Reg that it is in the process of selecting which open source Java Enterprise Edition (Java EE) framework to make available in the main part of its popular Linux distro. Sun's streamlined GlassFish 3.0 and the modular Application Platform are contenders.

During OSCON, Canonical and Ubuntu founder Mark Shuttleworth described how open source can drive innovation. And he called on the Linux community not to emulate Apple innovations, but instead to leap past Apple and make Linux a piece of art on the desktop within two years. Here's a recap from The VAR Guy.

We just received word today that the Third Circuit struck down a federal Internet censorship law as unconstitutional. The law, called the Child Online Protection Act, imposed civil and criminal penalties on those who place “harmful to minors” material on the Web. Under this law, no adult, no matter how mature or responsible, would have been allowed to see material that is deemed unfit for a child. The law would have forced vast swaths of constitutionally protected speech off of the Web.

All major computer retail stores will carry computers with Ubuntu pre-installed by the end of 2008 or early 2009, predicted a Canonical manager who met with The VAR Guy at OSCON. But this isn't another desktop Linux story. Here's the scoop.

In this article, learn how to be a more productive Linux systems administrator. These 10 essential tricks will lead you on your way to being one powerful Linux systems administrator. Learn about SSH tunnels, VNC, password recovery, console spying, and more. Examples accompany each trick, so you can duplicate them on your own systems.

Canonical is preparing an Ubuntu Server blitz at LinuxWorld Expo in August. Alfresco, IBM, Openbravo, Zimbra and others are expected to endorse Ubuntu Server at the conference, The VAR Guy learned during meetings at OSCON. Here's the scoop.

A look at zsh's unique use of input and output redirection.

An effort to rapidly reverse global warming is leveraging the collaborative methods of Linux and other open source software. Cquestrate aims to develop a cost-effective, "open" way to produce and introduce lime into the sea, where it will efficiently sequester dissolved CO2.

The SCO Group got bad news in court last week. Not an unusual event for this company, but I wish the need for such events would finally go away for good. I've now been writing about SCO for five years -- how time does fly when you have someone to despise. In my first column about SCO's decision go into the lawsuit business rather than having to do all the hard work of making a product that someone might want to buy, I thought that someone would just buy the slime off. I was wrong -- I guess there is some truth to the punch line of the old joke that "there are just some things a lawyer won't do." I guess IBM's lawyers could not stomach the idea of rewarding such repulsive behavior.

The Patent and Trademark Office has now made clear that its newly developed position on patentable subject matter will invalidate many and perhaps most software patents, including pioneering patent claims to such innovators as Google, Inc. In a series of cases including In re Nuijten, In re Comiskey and In re Bilski, the Patent and Trademark Office has argued in favor of imposing new restrictions on the scope of patentable subject matter set forth by Congress in § 101 of the Patent Act.

Intel released a new version of its Linux-compatible, open source library for multi-core C++ development. Version 2.1 of Intel Threading Building Blocks (TBB) offers performance improvements, adds a portable affinity mechanism, and improves the task scheduler to ease development for GUIs, network I/O, and artificial intelligence, says Intel.

After nearly a decade of active involvement in open source, IBM's commitment to Linux is broad and deep, said Inna Kuznetsova, the director of IBM Linux strategy. This vision of IBM's rapport with Linux is shared by most, but not all, IBM observers.

For years I have envied how easy my Windows- and Mac-based peers had it when traveling with their laptops. They connect to hotspots with ease, get online while I was still logging into root and running some tools. It just wasn’t fair. I wanted an integrated easy-to-use tool that did not require bringing up a shell or logging into root.
