As the industry call for cloud interoperability grows more fervent, open-source enterprise software company Red Hat has submitted its cloud platform, Deltacloud, to the DMTF (Distributed Management Task Force) as a potential standard for cloud interoperability, the company said Wednesday. "We do not want Deltacloud to be under the control of any one particular vendor, including Red Hat. If you want true interoperability and true portability, you need a third-party governance structure," said Red Hat cloud product manager Bryan Che during a webcast outlining the company's cloud-computing road map.

In a previous article I presented two new patch concepts (bcache and flashcache) for improving performance but using SSD’s as a caching mechanism for hard drives. In reality the caching is achieved by using a block device to cache another block device, but practically it’s using an SSD to cache hard drives. I’ve been waiting for some time for a patch that increases performance by using a cache that is larger than the disk cache and faster than the disk. SSD’s fit that bill pretty well, especially given their fantastic read performance compared to disks.

POSIX thread programming defines a standard set of C programming language types, functions, and constants—and pthreads provide a powerful tool for thread management. To use pthreads to the fullest, you'll want to avoid the common mistakes. One common mistake is forgetting to join joinable threads, which can create memory leaks and cause extra work. In this tips-oriented article, learn the basics of POSIX threads, see how to identify and detect thread memory leaks, and get solid advice for avoiding them.

I started a new job last week, as Technical Architect of Ubuntu. I'm thrilled to be here, I couldn't have crafted a more perfect job if I'd written the job description myself. I've been reflecting this week on how I got here. Many people know me for my involvement in Parrot, Perl, or Python, but my first love in free software was Linux, specifically Debian.

Ubuntu 10.10, codenamed Maverick Meerkat, is still two months from its final release. However, if the first alpha and the forecasts about it are an accurate indication, the release is already taking on a character all its own. Specifically, Maverick may be the release in which the Ubuntu version of GNOME differs from generic GNOME to the point where it should be recognized as a separate desktop -- call it Ubuntu GNOME.

Allison Randal has been appointed Technical Architect of Ubuntu at Canonical by Ubuntu founder Mark Shuttleworth. Randal is known for her work as an architect of the Parrot virtual machine and chairman of the Parrot Foundation and is a board member of the Perl and Python Foundations.

Last April (April-29-2010) there was a local event in Ecuador organized by AESoft, the Ecuadorian Software association. This event was names “Integrated Technologies” and was sponsored by Microsoft, CodePlex, Port25 and The Apache Foundation. On this conference Microsoft sent a message saying that they are Open Source friendly and they support Open Source development. I saw this even as a Microsoft response of the growing “Free Software” (as in Freedom) movement here in Ecuador. So Microsoft tried to convince the audience that they care about Open Source and there are a lot of OSS software they promote. - Martin Iturbide

Parsix GNU/Linux is a great little distro hailing from the exotic lands of Persia. It features a lovely customized GNOME desktop and lots of handy applications. It reminds folks of Ubuntu in many ways and is often described as a nice alternative to Ubuntu.

While our primary focus at Phoronix is on providing Linux benchmarks, we do enjoy trying out and benchmarking other operating systems like FreeBSD, Solaris, and Mac OS X. When Apple originally launched Mac OS X 10.6 "Snow Leopard" we were the first to provide detailed Mac OS X 10.6 benchmarks compared to Mac OS X 10.5 and also how Apple's new operating system at the time compared to Linux. We have continued to monitor the performance of Snow Leopard and found that some point releases had introduced some regressions and we have compared the performance of Mac OS X 10.6 to Windows 7 and Ubuntu 10.04 LTS. With Apple's release last week of the "Snow Leopard Graphics Update 1.0" that is reported to bring "stability and performance fixes for graphics applications and games in Mac OS X", our interest was piqued and we set out to run a new set of Apple OpenGL benchmarks. In this article we are looking at the OpenGL performance of Mac OS X 10.6, 10.6.2, 10.6.3, 10.6.4, and 10.6.4 with this graphics update installed.

Next month's revamped JavaOne conference, the first under Oracle's jurisdiction, will feature a keynote presentation from Oracle CEO Larry Ellison, as well as the latest on Java technologies ranging from the GlassFish application server to the JavaFX rich media platform....Ellison will take the stage Sept. 20 in San Francisco to discuss Oracle's vision and strategy for Java, Oracle said.

This article covers standard and journaling (also called journaling) filesystems with an emphasis is on ext2 (standard filesystem) and ext3 (journaling filesystem), but tools for other filesystems are mentioned too. Most of this material applies to both 2.4 and 2.6 kernels. Most examples in this article use Fedora 12, with a 2.6.32 kernel. Your results on other systems may differ.

Sometimes there are ideas that won’t go away. The other day, the Linux Magazine publisher asked me about a “cluster of smart phones.” As the processors in cell phones continue to get more powerful, the question is actually worth asking because many smart phones only need to be smart part of the time. Cluster HPC mavens are always looking for latent CPU cycles, why not check your pocket.

Trinity Audio Group announced an upgrade to its Linux-based "audio operating system," with an improved user interface, the real-time kernel 2.6.31, and a player that lets users change the speed of a song without altering pitch. "Transmission 4.0" is available as a download, on a USB stick, or preloaded on a netbook or ultra-mobile PC (UMPC), the company says.

Borders is now taking pre-orders for two seven-inch Android tablets, the $200 Cruz Reader and the $300 Cruz Tablet, and says the first of the devices will ship by the end of this month. Both tablets offer conventional backlit color touchscreens, but the Reader is resistive while the Tablet is capacitive, the reseller says.

Intel and Nokia are reviving the spirit of Second Life with plans for 3D interfaces on mobile devices running their MeeGo Linux distro. The companies have announced their first joint innovation center at Finland's Oulu University, and it will specialize in the development of 3D interfaces and environments for MeeGo.

Sometimes a project demands that we code in a thorough, “belt and suspenders” fashion. However many times it just isn’t necessary to go through all of the trouble — particularly when you’re trying out a new API for the first time and you really don’t need to build a production-ready project. I find myself often throwing together a quick app to test something — in most cases I create a single button to initiate the test.

Canonical's Ubuntu Community Manager Jono Bacon has announced that the next Ubuntu Developer Summit (UDS) will be take place from the 25th to the 29th of October, 2010 at The Caribe Royal hotel and convention centre in Orlando, USA. According to Bacon, the Ubuntu Developer Summit is "one of the most important events in the Ubuntu calendar and at it we discuss, debate and design the next version of Ubuntu".

Oracle has replaced Microsoft as the FOSS community’s number one enemy, according to Adobe System’s open source boss. David McAllister, the Flash and Photoshop maker’s open source and standards director, said in a blog post yesterday that the implosion of the OpenSolaris Governing Board highlighted how “the axis of evil has shifted south about 850 miles or so”.

In the course of a normal work day I take several little breaks to check the news. On my list of news sites are Slashdot, Linux Journal, and Linux Today. Frequently I see something that gives me an idea for an article. Sometimes I even find an article on a topic that I was planning to write about myself. Such was the case today when I came across this well-written piece from the Royal Pingdom Blog referenced on Linux Today. It’s about the failure of desktop Linux to break the 1% market share barrier, and I confess that it left me a little depressed. But I decided to add my two cents on the subject anyhow.
