RAID has still not been adopted by most end-users despite its inherent quality such as performance and reliability. Reasons such as complexity of RAID technology (levels, hard/soft), set-up, or support may be given. We believe the main reason is that most end-users own a vast amount of heterogeneous storage devices (USB stick, IDE/SATA/SCSI internal/external hard drives, SD/XD Card, SSD, etc.), and that RAID-based systems are mostly designed for homogeneous (in size and technology) hard disks. Therefore, there is currently no storage solution that manages heterogeneous storage devices efficiently. In this article, we propose such a solution and we call it PROUHD (Pool of RAID Over User Heterogeneous Devices). This solution supports heterogeneous (in size and technology) storage devices, maximizes the available storage space consumption, is tolerant to device failure up to a customizable degree, still makes automatic addition, removal and replacement of storage devices possible and remains performant in the face of average end-user workflow.

Does using a lightweight Linux desktop always mean trading lower resource usage for usability and features? Juliet Kemp reviews LXDE, one of the newest lightweight Linux desktops.

The Fedora project released a beta version of Fedora 13 (codenamed "Goddard"). The updated community Linux distribution is touted for features including automatic print-driver installation, the Btrfs filesystem, enhanced 3D driver support, revamped Python bindings, and the Zarafa groupware package, says the project.

Submissions for the Plasma Javascript Jam Session closed at the end of March and the judging commenced, with the community joining the judging panel as a collective "5th member". Every Plasmoid that was submitted was a success and a joy to try out: congratulations to all of those who participated. It was a competition with prizes up for grabs, however, so we had to make the required tough calls and declare some winners. Without further ado, here are your 2010 Javascript Jam Session competition crown bearers!

Despite the fact that version 2.1 of Google's mobile operating system has been available for several months, most devices are still running older versions. According to a device dashboard by Android developer Raphaël Moll, over the last 14 days only 27% of Android smartphones accessing the Android Market were running version 2.1. The majority – 38% and 32% respectively – were running versions 1.5 and 1.6. Version 2.0.1 accounts for just under 3% of users accessing the site and versions 1.1 and 2.0 barely troubled the scorers, presumably because updates are available for popular devices supplied with these versions.

hile reports suggest that Google is planning an Android or Chrome driven slate computer to rival the iPad, fuelled by some loose party talk by CEO Eric E. Schmidt, others have a date and price for their iPad-alike machine already. Take the Windows 7, sorry I mean Linux, powered WePad for example.

Finally Mark Jonson submitted to xen-devel mailing list patch for ZFS 24 support at Xen 4.0. Patch mentioned bellow was successfully tested at Xen 4.0 Dom0 with pvops kernel 2.6.32.11 on top of Fedora 12 via modifying Michael’s Young xen-4.0.0.7.fc12.src.rpm and direct patching xen 4.0 official tarball on Ubuntu Karmic Koala Server.

I've 10Mbps server port dedicated to our small business server. The server also act as a backup DNS server and I'd like to slow down outbound traffic on port 80. How do I limit bandwidth allocation to http service 5Mbps (burst to 8Mbps) at peak times so that DNS and other service will not go down due to heavy activity under Linux operating systems? You need use the tc command which can slow down traffic for given port and services on servers and it is called traffic shaping.

An article headline declares, "This is the year of the death of Linux on the desktop." These stories scroll along on the same news websites on the same day. To top it off, squeezed in between these headlines are even more predictions about things I thought were really dead… SCO for instance.

Z-push is an implementation of the ActiveSync protocol which is used 'over-the-air' for multi platform ActiveSync devices, including Windows Mobile, iPhone, Sony Ericsson and Nokia mobile devices.

Joystiq contacted Amanita Design founder Jakub Dvorský for to clarify the situation. "They told us, 'It's not Microsoft-exclusive, we don't want it.' They didn't cite the Mac and Linux versions [as reasons for the refusal] but it's quite clear that's the reason," Dvorský told Joystiq via email. As it did with Toki HD, Microsoft recommended Amanita Design pursue other publishers, an idea the team doesn't appear intent on exploring. "It means if we want to release the game on XBLA we must throw, probably, most of the profit out of the window -- to the publisher. Just because we created Mac and Linux versions."

I guess it was bound to happen sooner or later. I needed to get the laptop back into usable shape, and I did that by installing Ubuntu 10.04 LTS beta 2. While trying to do an update on my FreeBSD 7.3-release installation, well into the third day of the system building everything from source, I stopped that upgrade and tried to do one from packages only. Nope, it didn't work.

This past weekend (April 9th and 10th), I had the great pleasure to attend COSSFEST 2010 in Calgary. COSSFEST is the Calgary Open Source Systems Festival, a gathering of people whose passion is free and open source software, coming together to share information, exchange ideas, and otherwise talk about all things FOSS. Oh, and drink beer. And eat, too. Yeah, right . . . there's that karaoke thing we'd rather not talk about.

When Google announced a deal to acquire video technology company On2 last year, the move generated speculation that the search giant was aiming to liberate the VP8 codec in order to accelerate the advancement of standards-based open video. Google has remained silent about its plans for On2's intellectual property, but signs have emerged that the company is planning to do precisely what the speculators anticipated.

The popular Linux distribution, Fedora 13, has been released to its final beta and is chock full of features for enterprise use. Code-named Goddard, the beta version was released on Tuesday with the final version slated for May 18.

Google will soon make its VP8 video codec open source, we’ve learned from multiple sources. The company is scheduled to officially announce the release at its Google I/O developers conference next month, a source with knowledge of the announcement said. And with that release, Mozilla — maker of the Firefox browser — and Google Chrome are expected to also announce support for HTML5 video playback using the new open codec.

If you’re a Linux user, you’ve likely been asked at some point if you want Ext3, Ext4, XFS, ReiserFS, Btrfs, or one of many other filesystem acronyms. This choice confuses new and old users alike, and like all software, the options change as technology improves. Many people probably don’t care what filesystem they use as long as it’s stable and reasonably fast, but how do you know which one that is? This guide will attempt to cover the basic differences between the most common options, and provide the pros and cons of each choice.
