According to the guardian we have a new record in computer speed. Fastest supercomputer in the world proves one in a million billion.
Roadrunner was always expected to be fast out of the blocks. And after a test run one night in the city of Poughkeepsie, New York, its creators are far from disappointed.
The self proclaimed super computer was built from microchips originally destined for games consoles. Roadrunner is the world’s latest supercomputer. Not to long ago it was officially crowned the fastest computer around, having performed a record million billion calculations per second.
It harnesses the power of 116,640 processors working in concert and it weighs 230 tonnes taking at least 21 big trucks to move it to another location.
Google sent a letter to FCC today in which it detailed plans to provide wireless Internet access over TV “white spaces” in USA. White spaces are the unlicensed and unused TV airwaves, which TV broadcasters say will cause interference if they are used by others. Google’s letter today is perhaps a sign that it was not the inherent winner of the recent spectrum auction despite what people are saying.
Google was pressing the FCC to provide access to the white spaces prior to the auction results, however, Google’s letter today shows the company is still worried about there being enough competition in the industry.
It was reported that Google said that the white space, located between channels 2 and 51 on TV that aren’t hooked up to satellite or cable, offer a “once-in-a-lifetime opportunity to provide ubiquitous wireless broadband access to all Americans.” In addition, opening up the spectrum would “enable much-needed competition to the incumbent broadband service providers,” wrote Richard Whitt, Google’s telecom and media lawyer. In light of this big news , Google held a conference call discussing the letter today. Silicon Alley Insider has a live transcript here. The filing comes less than two weeks after Microsoft’s Bill Gates urged the FCC to free up the white space spectrum to use Wi-Fi. Google and Microsoft are part of a coalition of technology companies that are lobbying the FCC about white-space use.
This last week Google shared some of its plans for the future unification of the instant messaging (IM) market worldwide. This giant of modern Internet innovation, Google has become a great stabilizing force within the complex ecosystem of almost all the web-based services out there. When Google released Google Talk, a Jabber-based IM application, they promised all consumers that they would focus on protocol interoperability in order to ease communication between users of different IM systems. Since the birth of text-based Internet chat in the 1980s, countless IM protocols and applications have emerged to meet the rapidly growing demand for interactive text communication. AOL’s ubiquitous AIM service is thought to have over 50 million active users, a number that continues to increase as more consumers take up the habit.
Google chose to use Jabber’s Extensible Messaging and Presence Protocol (XMPP) for its own Google Talk application because XMPP is a well-documented open protocol fit for standardization and extension. The broad availability of XMPP support in open source communication applications ensures that users of all common platforms, including Linux and OS X, will be able to interact with Google Talk users. Working closely with the nonprofit Jabber Software Foundation (JSF), Google now plans to bring voice and video communication services to all XMPP-compliant InstantMessaging utilities. Described in a Jabber Enhancement Proposal that recently was seen, the new peer-to-peer voice and video standard is currently called Jingle. An open source implementation called Libjingle has already been released by Google under a BSD-style license. Basically a BSD license is very permissive, facilitating commercial redistribution even in proprietary applications, which means that closed source IM applications like AOL’s AIM client can take advantage of the code that is offered to them.
Google recently hired Sean Egan, one of the lead developers of a popular open source IM application called Gaim. Egan and other Gaim developers have already managed to integrate Google Talk’s voice features into the Gaim 2.0 branch, which is scheduled for release next month. (for the Interested users you might want to download the latest beta release of Google IM software)
After Google’s acquisition of a five percent stake in AOL last week, both companies decided that it would be advantageous to implement complete interoperability between Google Talk and AIM. Now that Google has the uncontested champion of IM technologies on its buddy list, it has the leverage it needs to get other services to jump on the interoperability bandwagon. After being separated by incompatible protocols for years, IM users may soon finally be able to communicate unimpeded, opening the door for a whole new level of IM innovation.
AutoCAD 2009 further enhances this amazing application used widely by both professionals and amateurs. The official website is still offering only older 2008 version, but this is a real deal. It will be out in stores soon with a high buying price like all the other Autodesk products prices. Although such cad software is very expensive , you can be sure you will get your money worth from Autodesk Autocad 2009. It comes bundled with lots of new things.
The AutoCAD 2009 portfolio is designed to improve the productivity of veteran users and allow new users to become productive more quickly,” said Amar Hanspal, senior vice-president, Platform Solutions and Emerging Businesses, Autodesk. “The innovations in AutoCAD 2009 extend to a product portfolio unmatched for breadth, depth, and best-in-class solutions that help our customers improve and bring to life their design ideas.”
Users are now allowed , through a new interface in AutoCAD 2009 , to view operations that are most relevant to the current workspace you’re working on. Extensible and very Customizable, this new interface allows a smooth transition from previous versions of AutoCAD software, Autodesk states. So now you don’t have to worry about backward cad compatibility issues.
As new productivity features in AutoCAD 2009 we have to mention the new Action Recorder, which reportedly streamlines drafting tasks by allowing any user to automate them without the need for advanced or difficult software programming. This really comes in handy and makes things in cad real easy. A mode-less layer manager lets users view changes to layer settings without exiting the layer manager. AutoCAD 2009 users also will find improvement to 3D navigation with new ViewCube and SteeringWheels tools. AutoCAD 2009 is certified for the 32-bit and 64-bit Microsoft Windows Vista operating systems.
