High-performance computing (HPC) for the past ten years has been dominated by thousands of Linux servers connected by a uniform networking infrastructure. The defining theme for an HPC cluster lies in the uniformity of the cluster. This uniformity is most important at the application level: communication between all systems in the cluster must be the same, the hardware must be the same, and the operating system must be the same. Any differences in any of these features must be presented as a choice to the user. The uniformity and consistency of running software on an HPC cluster is of utmost importance and separates HPC clusters from other Linux clusters.

Android is one of the most popular mobile operating systems (and it is based on the Linux kernel too.) However, diving into developing apps for Android can appear to be a bit daunting at first. The following how-to runs you through the basics of setting up an Android development environment on your Fedora machine. The basic workflow is to download the Android SDK, use the SDK to generate a quick first “hello world” application, then test out that application with either a physical Android device or the Android emulator.

Predictive analytics provider RapidMiner has acquired Radoop, a Hadoop Big Data analytics vendor.

If you haven’t heard, science has been experiencing some issues. Though most scientists believe in the ideals of openness, transparency, and reproducibility, the reality is that the incentive structure of academic research encourages exactly the opposite. So, scientists have a stronger professional incentive to get results published than to get them right. To make things worse, many scientists are stuck with outdated and closed source tools that aren’t up to the task of managing their increasingly complicated workflows.

The Freecode site has been moved to a static state effective June 18, 2014. Freecode has been the Web's largest index of Linux, Unix and cross-platform software, and mobile applications. Thousands of applications, which are preferably released under an open source license, were meticulously cataloged in the Freecode.database

Steam Marines an excellent looking squad based procedural death labyrinth set on a space-ship has now arrived on Linux after teasers from the developer.

Cloud surveys tend to miss the mark because they ask the wrong people or the people they are asking simply don't know the term. But that doesn't mean that consumers and business users alike aren't using the cloud because they definitely are --whether they know the term or not.

CAMBRIDGE, MA -- (Marketwired – June 18, 2014) -- TesoraTM, provider of an open and scalable database as a service (DBaaS) platform on OpenStack and the Trove project, today announced results of a survey of North American developer communities that found 15 percent were running private clouds on VMware software closely followed by 11 percent using OpenStack.

Red Hat today announced the acquisition of privately held eNovance in a deal that brings one of the top OpenStack cloud contributors into the Red Hat fold. The deal is valued at approximately 50 million euros in cash and 20 million euros in shares of Red Hat common stock, which converts to approximately $95 million USD.

An MIT spinoff is Kickstarter-funding its AllJoyn and OpenWRT Linux based “Q” system, which syncs its smart bulbs to mobile music it streams to a stereo. The Q name derives from the system’s Q Station router, “allowing you to both create a Q (queue) of music and send lighting Qs (cues) from the same smartphone app,” says MIT spinoff Belleds Technologies. (And if you also happen to envision hardware hacker hero Q from James Bond, so much the better.)

The Android-based Amazon Fire smartphone was launched today and includes some innovative features.

A new survey from database vendor Tesora found that businesses large and small are deploying OpenStack for private clouds.

First and foremost we would like to thank everybody that already supported the Randa Meetings fundraising. We have reached almost 1/3 of the our goal. Please help more and spread the word. If we reach our goal we can have an even more stable Kdenlive, more applications ported to KDE Frameworks 5, further progress on Phonon, a look at Amarok 3, even better KDE educational applications, a finished port of GCompris to Qt and KDE technologies, an updated KDE Book, more work on Gluon and a new and amazing KDE SDK!

When you’re learning to program in a new language or trying to master a new module, experimenting with a familiar and relatively simply project is a very useful exercise to help expand your understanding of the tools you’re using. Our Space Invaders clone is one such example that lends itself perfectly to Python and the Pygame module – it’s a simple game with almost universally understood rules and logic. While the Invaders meander their way down the screen towards you, it’s your job to pick them off while dodging their random fire. When one wave is conquered, another faster, more aggressive wave appears. We’ve tried to use many features of Pygame, which is designed to make the creation of games and interactive applications easier. We’ve extensively used the Sprite class, which saves dozens of lines of extra code in making collision detection simple and updating the screen and its many actors a single-line command.

In today's open source roundup: The Steamboy handheld Steam Machine. Plus: Bodhi Linux 3.0 release candidate, and Civilization IV might be coming to Linux.

Linux kernel 3.14 is one of the latest versions available, but it looks like this particular build has managed to break Wine for all the applications that were running in Windows 9x mode.

While the open source community is filled with some of the most talented minds in the world, fresh perspectives from the next generation of developers is essential to the continued pioneering spirit of open source projects. Such an injection of youthful enthusiasm lends new creative blood to the open source community, allowing projects to stay cutting edge and in keeping with current trends. read more
