NFS version 4, published in April 2003, introduced stateful client-server interaction and "file delegation," which allows a client to gain temporary exclusive access to a file on a server. NFSv4 brings security improvements such as RPCSEC_GSS, the ability to send multiple operations to the server at once, new file attributes, replication, client side caching, and improved file locking. Although there are a number of improvements in NFSv4 over previous versions, this article investigates just one of them -- performance.

One of the interesting aspects of Microsoft's long-running pursuit of Yahoo has been the potential knock-on effects for open source. Although the company doesn't make much of the fact, it uses a lot of free software, and has helped open source projects by employing some of the top hackers.

Dominic Sartorio began his career as a "traditional" software developer, but his career path has been indelibly marked by two things: a solid appreciation for the open source method, and a desire to understand the big picture of open collaboration and how that can ultimately create long-term benefits for the industry and for customers.

MontaVista announced that its Mobilinux 5.0 Linux distribution for mobile devices has been optimized for the Freescale i.MX31 system-on-chip (SoC). The optimization brings the total number of Freescale processors supported by MontaVista distributions to ten, says the company.

There are tools available to allow anyone to create and distribute a completely customized Ubuntu Based distribution using the Gnome Desktop. Many Kubuntu users would like to do the same thing but such tools are not fully compatible with KDE and the Kiosk tool does not change or remove all of the Kubuntu defaults so that a program like Remastersys can create a customized ISO with the defined changes. This How To is designed to address these issues and allow those interested in creating their own customized distribution based on Kubuntu.

Finally, the so called 'stable' version of Wine, 1.0, has been released on June 17, 2008. The last Wine review I made was to 1.0RC2 (release candidate 2), in which I already tested World of WarCraft, mIRC and DC++. I had no issues with World of WarCraft (tested using a trial account) which performs very well, without any visible problems, DC++ has minor stability problems and the mIRC scripts editor crashes, but otherwise, mIRC behaves good enough.

The Intel Atom powered Asus Eee PC 901 arrives before the month is out, with price drops for the existing 900 and 701 models. But when will Australia see the Eee 1000H model with real hard disk and larger keyboard? The Asus Eee PC revolution kicks into higher gear with the impending release of the Eee 901, an enhanced version of the recently released 900 series, replacing the Celeron 900MHz processor with the new Intel Atom processor running at 1.6Ghz – or in a turbo charged 1.9Ghz mode.

I was a little surprised to hear Nokia vice president of software Ari Jaaski's comments last week. Not long ago, Nokia got off to a great start by embracing open source for its mobile device business. But now, according to Jaaski, it's the open source developer community that needs to adapt to the ways of commercial software vendors, not the other way around.

The Linux Plumbers Conference is a working conference. LPC brings together the top developers working on the "plumbing" of Linux - kernel subsystems, core libraries, windowing system, etc. - and gives them three days to work together on core design problems. The conference is organized into several half-day microconferences focusing on individual subsystems. Since the microconfs are co-located, developers can meet face-to-face with experts from other subsystems to solve problems that span project boundaries. This kind of cross-project collaboration usually only happens in the unofficial "hallway track" at conferences. LPC makes the hallway track a priority.

Part two of a five part post series on setting up Linux and Unix servers securely.

Organic open source. Non-organic open source. Genetically modified free software. None of these are phrases that are in common usage but exploring what they mean is an interesting exercise. MySQL's Brian Aker used the first two terms when responding to a post by Linux kernel guru Ted T'so about what Sun was trying to do with its OpenSolaris project. I made up the third one myself! And whatever follows is my take on these terms.

DSL 4.4 was just released on June 9th, so this past weekend I installed it on my Compaq Deskpro Pentium III 800 Mhz machine. It only has 256 megs of RAM, so a lightweight distribution like DSL is a good choice for it. Their site claims you can run DSL 486 DX with 16 megs of RAM, so even this old Compaq should fly with what it’s got.

Most anyone in the free and open source Verio brings something extra to Linux: reliability. Click to learn about free test. Latest News about open source software realm can tell you not only that Linux is better than Windows, but also that it is an optimal alternative to the closed-source and proprietary operating system from Microsoft (Nasdaq: MSFT) Free Trial. Security Software As A Service From Webroot. Latest News about Microsoft.

In a combination news story and podcast, SugarCRM CEO John Roberts describes the state of his company, growing demand for Sugar as a hosted service -- and even a potential IPO (initial public offering) around 2010. Here's the scoop from MSPmentor.

In this blog about programming with BLAS, discover five tips to gain maximum performance for the IBM SDK for Multicore Acceleration 3.0. These five tips will let you leverage maximum performance from the BLAS library.

Free Software development is often a fun task for developers, and it is its low barrier to entry (on average) that makes it possible to have so much available software for so many different tasks. This low barrier to entry, though, is also probably the cause of the widely varying quality of the code of these projects. Most of the time, the quality issues one can find are not related to developers' lack of skill, but rather to lack of knowledge of how the tools work, in particular, the compiler. For non-interpreted languages, the compiler is probably the most complex tool developers have to deal with. Because a lot of Free Software is written in C, GCC is often the compiler of choice.

Asus will bring the Eee Box desktop to the UK in August, the company announced today. However, it confirmed to Register Hardware that machine will initially only ship with Windows XP Home Edition. The compact desktop contains not Intel's desktop-oriented Atom 230 processor, as anticipated, but the less power-hungry notebook version, the N270, Asus revealed. Both CPUs are clocked at 1.6GHz and contain 512KB of L2 cache. But the N270 consumes 2.5W of power, while the 230 has a 4.5W TDP.

I'd been complaining for at least a month about how I couldn't install Google Gears to gain offline functionality for Google Docs because Gears only supported Firefox 1.5 to 2.x, and I was running Ubuntu 8.04 with Firefox 3 and Debian Lenny with Iceweasel. Now that Gears works with Firefox 3, Ubuntu is taken care of. But I could've done this weeks ago, had I only come up with this solution: I could (and now am) running Google Gears with Docs in Puppy Linux.

The makers of Wine claim that version 1.0 is the first such "stable" release and have said that although compatibility is not perfect, thousands of applications are reported to "work very well." Member and former president of Linux Australia Jonathon Oxer told ZDNet.com.au that the Wine project is "an attempt to make Windows irrelevant." "Essentially, it's an effort to supplant the underlying operating system layer and allow Windows software to run on a Linux platform without requiring Windows to be installed," he said.

Since the dawn of time -- or, at least, the dawn of personal computers -- the holy wars over desktop operating systems have raged, with each faction proclaiming the unrivaled superiority of its chosen OS and the vile loathsomeness of all others.
