Do You want to get inside Apple's product?


Apple CEO Steve Jobs met Volkswagen's chief Martin Winterkhorn few days ago. And they plan to meet again for discissions. That fact makes some experts think Apple and Volkswagen decided to create "iCar" - vehicle with significant amount of media device aboard. Such a proposition have an opportunity to get reality because Apple have partnership with a lot of automakers including VW. It can be great step for Apple to create a branded car but don't You think that Apple goes out from its territory?

Skype was attacked by... Microsoft


Skype is on at last. Numerous users of peer-to-peer phone service Skype was unable to use it for almost 2 days. It was greatest outage of Skype for all its history. There was a lot of gossips about reasons of this problem. Someone told about DDoS, someone told about hackers etc. But Skype recently revealed the real reason of crash. The attacker was Microsoft! Cause was the regular Window Update. Skype reports that update caused massive computers reboot and then massive sign in of Skype users. There were some error in program code and because of it chain reaction crashed whole the peer-to-peer system.

iPhone's keyboard sucks

Usability study group User Centric shows in its study that iPhone's keyboard isn't as well as common QWERTY keyboards. Users on common keyboards make much less mistakes while typing texts or numbers and they are much quicker in typing texts. You can read more about it here.
Some pictures showing the difference between QWERTY keyboards and iPhone's keyboard:

Intel did it again!

Not so much time ago Intel seriously cut prices on its processors. And now Intel repeat its move. Great price cut on quad-core processors bring them much closer to the consumers.

Nanotechnology rapidly increases cooling efficiency

by Gabriel Ikram

The OCZ Hydrojet cooler uses an advanced heatsink material
The first heatsink to make use of directional carbon nanotubes, the OCZ Hydrojet, was on display at Computex 2007. Carbon nanotubes, an allotrope of carbon, are widely regarded as the next major thermal interface material because of their superior thermal conduction properties.

The contact base of the OCZ Hydrojet is made completely of carbon-nanotubes, which OCZ claims are five times more efficient than copper. Carbon nanotubes have been looked upon as a strong alternative to traditional copper based heatsinks. They are ideal for application in heat transfer products because of their impressive heat-conduction properties. Carbon nanotube based interfaces have been shown to conduct more heat than conventional thermal interface materials at the same temperatures. In addition, they have shown to be ballistic conductors at room temperature, which means electrons can flow through CNTs without collisions.

Carbon nanotubes are small wire-like structures made out of a sheet of graphene. The sheet of graphene used to construct CNTs is roughly one-atom thick, and is rolled up into a cylinder. The diameter of the cylinder ranges in the nanometers.

Unlike most other thermal materials, carbon nanotubes are able to move heat in one direction. On the other hand, copper, which is looked upon as one of the more superior thermal materials, moves heat radially. In the case of CNTs, heat is moved along the alignment of the nanotubes.

Quick and Dirty AMD K10 Cinebench

by Kristopher Kubicki

An early AMD "Barcelona" revision gets its first non-simulated benchmark


Earlier today, AMD announced that it successfully demonstrated Barcelona across the server market. The company did not publically state how fast the processor was running, the stepping of the processor, the processor thermal envelope or the eventual ship date.

We had the opportunity to benchmark the AMD Barcelona, native quad-core on an early stepping. We only had a few minutes to test the chip, but we were able to run a quick Cinebench before we were instructed to leave.

The AMD benchmark ran on a single-socket, K10 CPU running at 1.6 GHz on NVIDIA's nForce Professional 3400 chipset. According to the system properties, the AMD system used 4GB of DDR2-667.

The most similar Intel system we could muster up on such short notice was an Intel Xeon 3220. The Xeon X3220 is clocked at 2.4 GHz, and ran on Intel's Garlow platform (Intel X38). This system property profile stated the system utilized 4GB of DDR2-800.

Cinebench completed the default benchmark in 27 seconds for the 1.6 GHz K10; 17 seconds for the Intel Xeon X3220. The Kentsfield Xeon was 58% faster with a 50% higher clock frequency for Cinebench.

Both systems ran Windows 2003 R2, 64-bit.

AMD partner engineers tell DailyTech the chip we tested was the latest revision silicon. The same engineers claim 2.0 GHz Barcelona chips are making the rounds, with 2.3 GHz already on the desktop and server roadmaps.

AMD's current guidance suggests a late July announcement for Barcelona. However, when DailyTech tracked down the individual partners named in AMD's press release, all cited "optimistic September" ship dates for motherboards.

Raytheon Develops World's First Polymorphic Computer

EL SEGUNDO, Calif., March 20, 2007 -- The world's first computers whose architecture can adopt different forms depending on their application have been developed by Raytheon Company (NYSE: RTN).

The architecture of the MONARCH processor with key elements identified
The architecture of the MONARCH processor with key elements identified

Dubbed MONARCH (Morphable Networked Micro-Architecture) and developed to address the large data volume of sensor systems as well as their signal and data processing throughput requirements, it is the most adaptable processor ever built for the Department of Defense, reducing the number of processor types required. It performs as a single system on a chip, resulting in a significant reduction of the number of processors required for computing systems, and it performs in an array of chips for teraflop throughput.

"Typically, a chip is optimally designed either for front-end signal processing or back-end control and data processing," explained Nick Uros, vice president for the Advanced Concepts and Technology group of Raytheon Space and Airborne Systems. "The MONARCH micro-architecture is unique in its ability to reconfigure itself to optimize processing on the fly. MONARCH provides exceptional compute capacity and highly flexible data bandwidth capability with beyond state-of-the-art power efficiency, and it's fully programmable."

In addition to the ability to adapt its architecture for a particular objective, the MONARCH computer is also believed to be the most power- efficient processor available.

"In laboratory testing MONARCH outperformed the Intel quad-core Xeon chip by a factor of 10," said Michael Vahey, the principal investigator for the company's MONARCH technology.

MONARCH's polymorphic capability and super efficiency enable the development of DoD systems that need very small size, low power, and in some cases radiation tolerance for such purposes as global positioning systems, airborne and space radar and video processing systems.

The company has begun tests on prototypes of the polymorphic MONARCH processors to verify they'll function as designed and to establish their maximum throughput and power efficiency. MONARCH, containing six microprocessors and a highly interconnected reconfigurable computing array, provides 64 gigaflops (floating point operations per second) with more than 60 gigabytes per second of memory bandwidth and more than 43 gigabytes per second of off-chip data bandwidth.

The MONARCH processor was developed under a Defense Advanced Research Project Agency (DARPA) polymorphous computing architecture contract from the U.S. Air Force Research Laboratory. Raytheon Space and Airborne Systems led an industry team with the Information Sciences Institute of the University of Southern California to create the integrated large-scale system on a chip with a suite of software development tools for programs of high value to the Department of Defense and commercial applications. Besides USC major subcontractors included Georgia Institute of Technology, Mercury Computer Systems and IBM's Global Engineering Solutions division.

Raytheon Space and Airborne Systems is the leading provider of sensor systems giving military forces the most accurate and timely information available for the network-centric battlefield. With 2006 revenues of $4.3 billion and 12,000 employees, SAS is headquartered in El Segundo, Calif. Additional facilities are in Goleta, Calif.; Forest, Miss.; Dallas, McKinney and Plano, Texas; and several international locations.

Raytheon Company, with 2006 sales of $20.3 billion, is an industry leader in defense and government electronics, space, information technology, technical services, and business and special mission aircraft. With headquarters in Waltham, Mass., Raytheon employs 80,000 people worldwide.
