Top Country in Porn and Sex Searches
Posted by Muhammad Nasir on 19:57
Google trends analyses a Portion of Google web searches tells how many searches have been done by user for any particular words. So we can track number of searches for particular word or term. By using this Tool we can tell that which Country of the World have searched the word "Porn" or Sex. But overall it is very difficult to tell that which country have searched or watched porn videos a lot.

| Top Porn Searches |
In 2010, Some blogs said that Pakistan is number one country in searching the word "Sex" but by just looking this things we can not say that Pakistan is number one country in searching porn websites. Because many and different types of word can be use for searching these porn websites.
So by looking only one word analyses we cannot blame to any country that it has number one in Porn searching.

The Power of Watson
Posted by Muhammad Nasir on 10:58
Watson is one of the first big steps toward machine intelligence using existing technologies. What it was designed to do was to parse a question into component parts, analyze the components, find matching results, and finally attach a value to those results so that the most likely answer could be brought to the surface.
Watson was crippled to play in the "Jeopardy" TV show because it needed to be as limited as a human. So it had a physical rather than electronic connection to the buzzer, and it was only allowed to use information loaded into local storage. It couldn't use the Web or even IBM's vast knowledge databases. Neither of those limitations will be applied to the eventual productized system.
A division was created around Watson and an initial market identified for it -- the medical market. When given a series of symptoms, Watson will identify the top likely causes, which will then define a series of tests to confirm the actual diagnosis.
This is as opposed to current diagnostic practices, which involve a doctor or doctors listening to patients describe their symptoms and then guessing, based on knowledge and experience, which causes are most likely. The problem with this way is that people suck at this approach, which is why so many people are misdiagnosed.

China Builds World-Class Supercomputer Sans Intel, AMD
Posted by Muhammad Nasir on 00:42
China shook the international establishment last year when it unveiled the fastest supercomputer on the planet, besting its closest American rival by the number-crunching equivalent of a country mile. But last week, the Middle Kingdom’s newest supercomputer arrived with a much greater rumble — even though it’s unlikely to crack the world top 10.
Revealed last week at a conference in Jinan, China and profiled in The New York Times , the Sunway BlueLight MPP supercomputer doesn’t use microprocessors from Intel or AMD. It uses a chip designed by the Chinese themselves — and it’s not the Chinese microprocessor the supercomputing community was expecting. In other words, the Chinese are developing two microprocessors that could shift not only bragging rights in the worldwide supercomputer game, but the general market for server silicon.
“It shows that there’s a significant effort underway in China to build multicore processors that can be put into the world’s fastest computers,” Jack Dongarra, the University of Tennessee professor who oversees the annual list of the Top 500 supercomputers , tells Wired. “And you have to wonder what their strategy is in terms of pushing these chips outside of their borders.”
Before the Sunway was uncloaked, Dongarra was expecting China to reveal a computing cluster based on an eight-core chip its engineers were developing under the “Loongson” or “Godson” name. Instead, the Sunway uses a previously unknown chip dubbed the “ShenWei SW-3.” Harnessing 8,700 of these chips, the cluster can, in theory, handle more than 1,000 trillion calculations a second — aka a petaflop.
That will likely put the Sunway among the top 20 fastest supercomputers when Dongarra and crew unveil their official list next month. For the University of Tennessee computer scientist, this shows that China is gaining ground on the big American chip-makers faster than expected. “China hasn’t done much in the way of microprocessor development over the past 20 years,” he says. “But it won’t take them 20 years to catch up. It’s going to take them a very short time.”
Intel and AMD did not respond to a request for comment. Nor did the unnamed Chinese representative who emailed the Sunway’s benchmark numbers to Dongarra last week. Dr. David K. Kahaner, the president and founding director of the Asian Technology Information Program , tells us that the Chinese briefed him on the Sunway in April and that they claimed it would achieve 75% efficiency on the Linpack benchmark, which means its average performance would be about 75% percent of its peak one-petaflop speed. This is similar to what the Chinese claimed last week.
According to reports from Jinan , the ShenWei microprocessor was designed at a supercomputing institute in China and manufactured in Shanghai, and it uses a new instruction set — not the venerable x86 instruction set used by Intel and AMD. The chip runs at about 1GHz, which is well under the speed of the latest Intel and AMD chips, but a lower clock also means it consumes less power.
Last fall, a separate Chinese operation unveiled the Tianhe-1A, based on Intel’s Xeon processors, which was then the fastest supercomputing on earth. It was soon topped by a Japanese cluster known as the K Computer, and the Japanese will likely retain their crown when the list of the Top 500 supercomputers is officially revealed. But in many ways, the Sunway has already stolen its thunder.
In revealing the Sunway — which was apparently installed in Jinan in September — the Chinese also unveiled a list of the country’s top 100 supercomputers. Eighty-five still use Intel and fourteen used AMD, but the plan is to move to the lot towards homegrown hardware. The supercomputing game isn’t a huge part of Intel’s or AMD’s business, but there’s a certain amount of prestige wrapped up in these massive machines, and the same chips can be used in ordinary servers.
“Don’t think of this in terms of supercomputing,” says Dongarra. “There’s a low-end that where these chips can work. You can imagine these chips replacing all the Intel chips in the China.”

What does Mean of Core i3, Core i5 and Core i7
Posted by Muhammad Nasir on 09:56
Core i3, Core i5 and Core i7 Mean:
Many people do not know what is Core i3, Core i5 and Core i7 mean. First of all we have to understand what is Core. After this we can understand what does Core i3, Core i5 and Core i7 mean. These terms basically we use when we want to buy any laptop and if we are telling somebody about our laptop specifications.
Core as same as processor but when we say single core it mean our system or laptop can perform only one instructions at a time. A multi-core processor can perform more than one instruction at a time.
i3, i5, i7 are Intel series processor. core i3 has a low level and also has less processing power but it does not mean that we cannot do any thing by using a core i3 processors laptops. Core i5 is more power than core i3. Similarly core i7 is more powerful than core i3, and i5 processors.
When we buy a laptop we do not know about these terms. So which type of Laptop we should buy it depends on our uses of laptop. If we simply want to watch Movies and any other multimedia and some other photo editing tools then core i3 is best. But if we want to run powerful and havy application we should buy core i5 or core i7.
The prices of thes laptops also differs.
How many cores do i3, i5, and i7′s have?
A Dual-core processor has two cores.
A Quad-core processor has four cores.
An i3 processor has 2 cores.
An i5 processor has 2 or 4 cores (depending on the model you have.)
An i7 processor has 2, 4 or 6 cores (depending on the model you have.)

Watson, IBM Watson computer, SuperComputer
Posted by Muhammad Nasir on 05:15
Watson is an artificial intelligence computer system capable of answering questions posed in natural language,[2] developed in IBM's DeepQA project by a research team led by principal investigator David Ferrucci. Watson was named after IBM's first president, Thomas J. Watson.[3][4]
In 2011, as a test of its abilities, Watson competed on the quiz show Jeopardy!, in the show's only human-versus-machine match-up to date.[3] In a two-game, combined-point match, broadcast in three Jeopardy! episodes February 14–16, Watson beat Brad Rutter, the biggest all-time money winner onJeopardy!, and Ken Jennings, the record holder for the longest championship streak (75 days).[5][6] Watson received the first prize of $1 million, while Ken Jennings and Brad Rutter received $300,000 and $200,000, respectively. Jennings and Rutter pledged to donate half their winnings to charity, while IBM divided Watson's winnings between two charities.[7]

Solar Energy, What is Solar Energy
Posted by Muhammad Nasir on 09:03
Solar power involves using solar cells to convert sunlight into electricity, using sunlight hitting solar thermal panels to convert sunlight to heat water or air, using sunlight hitting a parabolic mirror to heat water (producing steam), or using sunlight entering windows for passive solar heating of a building. It would be advantageous to place solar panels in the regions of highest solar radiation.[26] In the Phoenix, Arizona area, for example, the average annual solar radiation is 5.7 kW·h/(m²·day),[27] or 2.1 MW·h/(m²·yr). Electricity demand in the continental U.S. is 3.7×1012kW·h per year. Thus, at 20% efficiency, an area of approximately 3500 square miles (3% of Arizona's land area) would need to be covered with solar panels to replace all current electricity production in the US with solar power. The average solar radiation in the United States is 4.8 kW·h/(m²·day),[28] but reaches 8–9 kWh/m²/day in parts of the Southwest.
At the end of 2009, cumulative global photovoltaic (PV) installations surpassed 21 GW[6][7][8] andPV power stations are popular in Germany and Spain.[9] Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 megawatt (MW) SEGS power plant in theMojave Desert.[10]
China is increasing worldwide silicon wafer capacity for photovoltaics to 2,000 metric tons by July 2008, and over 6,000 metric tons by the end of 2010.[29] Significant international investment capital is flowing into China to support this opportunity. China is building large subsidized off-the-grid solar-powered cities in Huangbaiyu and Dongtan Eco City. Much of the design was done by Americans such as William McDonough.[30]
