The Hadoop ecosystem relies on composability — the ability to use output from one tool as input to the next — to efficiently process data at scale, from simple projects, to processing streams of real-time data, to building data warehouses.

The AMD Radeon Linux testing consisted of a mixture of AMD Radeon HD 5000 and Radeon HD 6000 series graphics cards. As mentioned in the earlier article and numerous other Phoronix pieces, the open-source Linux graphics driver support for the very latest Radeon HD 7000 "Southern Islands" graphics cards is still a work-in-progress and maturing within the new "RadeonSI" driver. Radeon HD 7000 testing will come separately due to the less than complete OpenGL support at this time. For Radeon HD 7000 series users the best bet right now is just using the proprietary AMD Catalyst graphics card. With the Radeon HD 4000 series GPUs and older not being supported by the mainline Catalyst driver and the legacy Catalyst driver not working well on the latest Ubuntu Linux release, this limited the AMD testing to the HD 5000/6000 families.

When developing systems or devices based on embedded Linux or Android, does it make sense to use commercial development tools? In this guest column, Brad Dixon, Director of Open Source Solutions at Mentor Graphics, suggests several reasons why commercial development tools and support can potentially save time, resources, money, and opportunity costs.

Previously, I erroneously titled my column as ""SIGALRM Timers and Stdin Analysis". It turned out that by the time I'd finished writing it, I had spent a lot of time talking about SIGALRM and how to set up timers to avoid scripts that hang forever, but I never actually got to the topic of stdin analysis.

Last week North Bridge Venture Partners and Black Duck Software released the 7th Annual Future of Open Source survey. Previous years' surveys have generated interest industry-wide, with implications that cross industries and ecosystems.

The Obsidian project, an open source unit test generator built for the JUnit framework, has been in development for two years at the College of Charleston's Cyber Infrastructure Research and Development Lab for the Earth Sciences (CIRDLES). Using open source components such as JUnit and Netbeans, Obsidian concentrates on building standardized test implementations that are comprehensive and easy to maintain.

New native configurations for GDB 7.6 include AArch64 GNU/Linux (64-bit ARM on Linux), FreeBSD/PowerPC, x86_64/Cygwin, and Tilera TILE-Gx GNU/Linux. New target configurations are ARM AArch64, ARM AArch64 GNU/Linux, Lynx 178 PowerPC, x86_64/Cygwin, and Tilera TILE-Gx GNU/Linux.

Power management is always an issue in portable device. Be it a laptop or a mobile device, you always want the battery to last as long as possible without it dying on you. If you are running Linux on your laptop, you can make use of the TLP module to manage your computer’s power usage in the background.

While the open-source Intel Linux graphics driver already has support for at least 36 variants of Intel's forthcoming Haswell processors with faster integrated graphics, it turns out some were missing. The reserved PCI IDs weren't added and it turns out that some products are actually going to be using the IDs.

A web hosting company has publicly shared their thoughts on the Btrfs file-system for Linux. While often discussed as the next-generation Linux file-system, Btrfs isn't fully baked for use in a production world quite yet.

Last week, I attended my first OpenStack Summit as part of a team from Red Hat helping to launch a new community distribution of the popular open source infrastructure as a service (IaaS) project.

Dot Categories: Community and EventsThe Akademy 2013 Program Committee is proud to present the Akademy 2013 Presentation Schedule. Reflecting the scope of KDE, the schedule includes a wealth of interesting, timely and valuable topics. From the proposals submitted, 32 were selected to address currently relevant topics of most interest to the KDE Community.

Rust, the new programming language being developed by the Mozilla project, has a number of interesting features. One that stands out is the focus on safety. There are clear attempts to increase the range of errors that the compiler can detect and prevent, and thereby reduce the number of errors that end up in production code.

During my second year at Shreemati Nathibai Damodar Thackersey (SNDT) Women's University, the first of its kind in India as well as in South-East Asia, I attended a workshop on Python and Orca by Krishnakant Mane. My classmates and I were novices to free and open source software (FOSS) and astonished when we saw a visually impaired person using a computer with the same ease as we did. I was aware of Linux and had learned the basics of Unix as a freshman, but I had never used Ubuntu, which I thought might be command driven. It had a great interface and there was a lot of new technology for us to learn. That day not only was our class introduced to a new world of open source, but so was the university as a whole. 

Dot Categories: Graphics and ArtKO GmbH announces extensive support services for Krita, the award-winning graphics application. Krita is an advanced paint application with a complete set of professional paint tools that can handle extremely large images effortlessly. It is particularly well-suited for special effects work in the movie industry.

Chemistry is not the most open field of scientific endeavor; in fact, as I began working more in the area (coming from a background in physics), I was surprised with the norms in the field. As a PhD student way back in 2003, I simply wanted to draw a 3D molecular structure on my operating system of choice (Linux), and be able to save an image for a paper/poster discussing my research. This proved to be nearly impossible, and in 2005 a group of like-minded researchers got together at a meeting of the American Chemical Society and formed an unorganization: The Blue Obelisk (named after their meeting place in San Diego).

The final release of X.Org Server 1.15 isn't likely until September or October of this year, but Keith Packard decided to do this 1.15 snapshot to take care of a previously reported security vulnerability. Aside from closing out the CVE, there's various other updates too. There isn't anything too extremely exciting about the 1.15 development state but there's some fixes, X Input and XKB updates, and a new ZoomModes monitor option for the X.Org Server configuration.
