Raspberry Pi powered juggling performance

Thursday 21st of August 2014 07:00:00 AM

Flashing pins are spinning tens of feet into the air on a pitch dark stage. It's a juggling performance. All of the pins are perfectly synchronized to flash different colors in time to the music. It's part of the magic of theater and a special night out with friends to enjoy a distraction from daily life. Part of the magic—and why it's called magic—is that the audience doesn't know how these secrets are made backstage.

Using Clocker and Apache Brooklyn to build a Docker cloud

Wednesday 20th of August 2014 11:00:00 AM

With the growing potential of Docker, it's becoming clear that the future of at least some of the data center is going to be containerized. But there are still challenges in getting containerized applications deployed and managed across real and virtual hardware.

Why the operating system matters in a containerized world

Tuesday 19th of August 2014 11:00:00 AM

Applications running in Linux containers are isolated within a single copy of the operating system running on a physical server. This approach stands in contrast to hypervisor-based virtualization in which each application is bound to a complete copy of a guest operating system and communicates with the hardware through the intervening hypervisor. As a result, containers consume very few system resources such as memory and impose essentially no performance overhead on the application.

Open source forms the backbone of the most significant projects

Tuesday 19th of August 2014 09:00:00 AM

Improve your online relationships with a dose of empathy

Monday 18th of August 2014 11:00:00 AM

Humans have always formed communities. They are necessary for support both physically and, according to psychologists, emotionally as well. Until recently, though, the development of communities was constrained by geography. If you wanted to raise a barn or have a quilting circle, for example, only the folks nearby could participate. The Internet, though, has allowed communities to grow in ways that are not bounded by geography.

Look inside building an open source map app

Monday 18th of August 2014 07:00:00 AM

Imagine yourself walking down the middle of a crowded street in a complex city like Cairo. Suddenly a protest builds ahead. A mass of people, cutting off the road. You try to evade, but then violence breaks out in mere seconds. You need help. Someone else, a car to get you out. A phone call might suffice, but wouldn't it be easier to notify all your friends that this place is dangerous and that you need their assistance? This is where a map-based social network could come into play.

An open source approach to fraud prevention

Thursday 14th of August 2014 11:00:00 AM

Companies often discuss completely changing their back-end infrastructure, but rarely do. The cost of diverting resources and slowing product enhancements during the transition—as well as the impact on customers— can strike fear into the hardiest of executives, chief technical officers, and developers.

Why isn't all government software open source?

Thursday 14th of August 2014 09:00:00 AM

The federal government is the single largest purchaser of code in the world. So why is this code—taxpayer-funded and integral to the day-to-day working of our democracy—so often hidden from public view? There are two sides to answering that question: Why does the government so often build on closed platforms, and once built, why isn't the code released to the public?

Red Hat CTO unexpectedly quits, amid rumors of executive 'friction'

No-one among the rank and file at Red Hat seem to have seen this coming. In a move the Linux giant's staffers said was "shocking" and a "punch in the gut," long-time Red Hat chief technology officer Brian Stevens has resigned. In a short press release, the company announced: "Brian Stevens will step down as CTO." In the same release, Red Hat's president and chief executive Jim Whitehurst said, "We want to thank Brian for his years of service and numerous contributions to Red Hat’s business. We wish him well in his future endeavors." Read more

Is Microsoft engaging in digital imperialism?

Windows, the common carrier of Microsoft, is such a sordid mess that it suffers regular glitches and conducts mass surveillance on users. Microsoft knows that without Windows it cannot survive, so dirty tricks resume in a very big way. This is not a beep on the radar but somewhat of a surge. Nothing is going to change in Munich, but Microsoft is trying to maintain an international/universal perception that the migration to GNU/Linux was a disaster. Numerous anonymous blogs were created to attack Munich over this and provocateurs of Microsoft loved citing them, only to be repeatedly proven wrong. Microsoft is trying to make an example out of Munich in all sorts of nefarious ways. We need to defend Munich from this malicious assault by the convicted monopolist and corrupt enterprise that’s acting as though it fights for its very survival (while indeed laying off tens of thousands of employees).

Shortlist of open source software used at NASA lab

Yes! We use a lot of open source. The short list includes Python, GitHub, Processing, VLC, jQuery, D3.js, Blender, VRUI, ImageJ, VMD, ParaView, MeshLab, VNC, ImageMagick, SWIG, Emacs, and many more. We like using open source because it gives us more flexibility because of licensing and allows us the opportunity to contribute back to the community using our expertise. Our favorite open source project that we work on is OpenMDAO. This project is run out of another Division at our Center. Our team provides some programming support. OpenMDAO is an open source Multidisciplinary Design Analysis and Optimization (MDAO) framework, written in Python. You can use it to develop an integrated analysis and design environment for your engineering challenges. Read more

GSoC: Thumping the Malaria and voyaging in cosmos with KStars

Let's talk about my project now. KStars is desktop planetarium application under KDE Education Projects. I developed QML based cool interface to enable users to browse through image database of community of astrophotographers (i.e. astrobin.com) which contains more than 1,20,000 (number is increasing everyday) real time and very high resolution images along with various information related to them (i.e. Date on which image was captured, Bortle Dark-Sky Scale, RA Centre, DEC Centre, Telescope or Camera used, Description added by astrophotographer etc). I am sure that this browser will enthrall school children by showing them real time images of stars and galaxies located at hundreds of light year far from earth. Read more
