Facebook to Become the Third Biggest Website Soon

This time Yahoo still the third biggest website on the Internet after Google and Microsoft sites, with 622 million unique visitors worldwide in July. But the gap between Yahoo and Facebook is only 50 million visitors and if current trends continue, by year’s end yahoo will lose 3rd position to Facebook. Facebook has 572 million unique visitors in July according to comScore.
Google as the biggest company online, facing the the great challenge from social networking sites. Yahoo, the web portal turned media company has been enjoying a solid third place worldwide when it comes to audience, ensuring it some healthy revenue and the luxury of figuring out what it wants to be. But Facebook is gaining fast in terms of unique visitors and may very well overtake Yahoo to become the third largest site on the web by the end of the year and probably sooner.
In July, Facebook gained 20 million visitors from the month before, whereas Yahoo stayed completely flat. This clearly showing that nobody is quitting Facebook over privacy issue or any other issues arise in recent past. Yahoo has about 620 million visitors, according to comScore, enough to place it behind Google and Microsoft globally. Facebook keeps on growing, by 50 percent in the past year in terms of unique visitors. It now gets about 570 million unique visitors each month, very close to Yahoo's numbers. Facebook now officially says it has 500 million active users, coz the unique visitors doesn't translate into registered users.

Facebook also overtakes Google's social networking platform Orkut in India. India, one of the few countries where Orkut retained the top spot amongst social networking websites. According to marketing research company comScore, Facebook grabbed the number one ranking in the social networking category for the first time in July with 20.9 million visitors, up 179 per cent versus year ago. Orkut registered a growth of only 16 per cent in the same time period.

World’s Fastest CPU at 5.2GHz by IBM

The New zEnterprise 196 is world's fastest, most powerful microprocessors running at 5.2Ghz, capable of executing more than 50 billion instructions per second. This new IBM microprocessor technology has new software to optimize performance of data-heavy workloads, including up to a 60% improvement in data intensive and Java workloads. The quad-core z196 runs at an astonishing 5.2GHz, taking the title from IBM's own 4.7GHz Power6 CPU. The new chip contains 1.4 billion transistors - 300 million more than Intel's six-core desktop CPUs - on a 512mm2 package made using a 45nm manufacturing-process.
Each core has been given 1.5MB private L2 cache as well as access to 24MB shared L3 eDRAM cache. Somewhat uniquely, the z196 also has access to a fourth layer of cache off-chip. Six of these CPUs can be installed into a multi-chip module (MCM) and will connect to each other through two controllers with a total of 192MB shared L4 cache via a 40GB per second link. Apparently the processors are so fast that this extra level of memory is necessary to ensure that they are constantly fed with data.

Another relatively unusual feature is the use of the CISC-based z/Architecture, as opposed to a more common RISC ISA. CISC has largely been superseded by RISC, but is still useful for certain operations that require very large amounts of memory to properly run.

A water cooling option is also available for the z196 that can reduce energy use by up to 12%.(9) In a normal data center environment, water cooling reduces the required system air flow by more than 20%, while removing more than 70% of the system air heat load.

The z196 will find its way into IBM's Z-series mainframes and should start shipping at some point in September. Intel and AMD fighting for the fastest CPU crown, but IBM beat them and make a record for the CPU with the highest clock-speed.
