The paper considers a mathematical model of the behavior of an assembly of N stars. The 'Kepler' Microsoft Windows demo application based of this model enables to perform real-time simulation of star clusters dynamics for N~=2500. Such performance rate is possible through the use of the Intel Integrated Performance Primitives (IPP) library. The paper also estimates the efficiency of the IPP application and provides an example of C-code with the IPP functions calls. Computer-simulated images of the spiral galaxy forming process, as well as the real galaxies photos, are presented.Introduction
Realistic simulation of star clusters dynamics, for example, the dynamics of galaxies, may be of interest to a broad sections of specialists – from game developers up to astrophysics scientists. While, in general, this task is not very difficult from the mathematical point of view (see section 1), it requires large computational resources if the number of stars N is big enough. Further you can see that the time of computing increases as the square of N, which presents the main difficulty for real-time simulation of star assemblages, even on modern computers. To solve the problem, we used the Intel Integrated Performance Primitives (IPP) software library [1], which enabled to increase the calculation speed and perform 2000 – 2500 stars assemblage behavior in real time. Destination and capabilities of this software are briefly described in in section 3.

"Google is working to bring Web software to televisions through a partnership with Intel, Sony and Logitech, according to two people involved in the discussions with the companies. The project, called Google TV, uses Intel chips, with Switzerland's Logitech developing a keyboard that operates as a remote control, said one of the people, who declined to be named because the matter isn't public."

"Researchers at the Massachusetts Institute of Technology have released research detailing how molecules in chips can self-assemble, potentially reducing manufacturing costs. The researchers have developed a technique in which polymers automatically fall into place to create an integrated circuit." Uhm people, have we learned nothing?

"In this article, the authors investigate the impact of DRM restrictions on the demand for music downloads. [A new model] estimates the impact of DRM on consumers' willingness to pay for songs (both favorites and nonfavorites) and on the producer revenues and profits. Based on two studies of more 2000 college students, the results suggest that despite the potential advantages offered by some DRM restrictions, on balance the elimination of DRM has a net positive impact on producer revenue, profit, and consumer welfare."

"By encouraging more people to post videos in Wikipedia articles, we can bring theora video played in html5 to a very large audience. Currently, there are very few wikipedia articles that have videos. We hope that this campaign will bring thousands more to the site and show people how great theora can be. HTML 5 video, which plays without Flash, is a wonderful step towards a more open web - but if it depends on proprietary codecs like h.264, we will still be stuck with a gatekeeper for online video."

"Google is changing the way it handles the unique identifier that accompanies each installation of its Chrome browser. As noticed by H-Online, a Google white paper says the company will now delete the unique ID after the browser updates itself for the first time. Google has confirmed with The Reg that the change will be made with the upcoming Chrome 4.1."

Today's mobile space is owned by the likes of Nokia, RIM, Apple, and Google. While some of these corporations have embraced some open source components, a full FLOSS solution has yet to gain traction. Why? Blogger Bradley M. Kuhn posts thoughtful analysis of the current state of Open Source in the mobile space.

Jim Bray, who played a major role in the XML standardisation effort, has joined Google to work on Android, and his words for the iPhone are pretty harsh. "The iPhone vision of the mobile Internet's future omits controversy, sex, and freedom, but includes strict limits on who can know what and who can say what. It’s a sterile Disney-fied walled garden surrounded by sharp-toothed lawyers. The people who create the apps serve at the landlord's pleasure and fear his anger. I hate it."

"Following two unsuccessful attempts at forcing ISP Telenor to block The Pirate Bay in Norway, the IFPI and performing rights outfit TONO have abandoned their legal action. The case will not now head to the Supreme Court but instead the entertainment groups will pin their hopes on new legislation."

"A number of humorous yet undocumented features are hiding beneath the surface of some of the most popular open source software applications. Although easter eggs are generally easy to spot when you can look at an application's source code, there are a few that aren't widely known."

"In March 2008, Microsoft and Nokia announced their commitment to make Silverlight available for certain Nokia phones running the Symbian operating system. Microsoft is finally ready to make a beta of that code available. Microsoft briefly posted, then pulled, the download of the beta of the Silverlight for Symbiancode on March 11, as well as the associated developer tools for that release. I grabbed the description of the downloads before they were zapped."
