An Ethical Hacker is one name given to a Penetration Tester. An ethical hacker is usually employed by an organization who trusts him or her to attempt to penetrate networks and/or computer systems, using the same methods as a hacker, for the purpose of finding and fixing computer security vulnerabilities. Unauthorized hacking (i.e., gaining access to computer systems without prior authorization from the owner) is a crime in most countries, but penetration testing done by request of the owner of the targeted system(s) or network(s) is not.
A Certified Ethical Hacker has obtained a certification in how to look for the weaknesses and vulnerabilities in target systems and uses the same knowledge and tools as a hacker.
Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, said two Chinese cities with millions of inhabitants each, Chongqing and Chengdu, had been in the minivan-sized satellite's projected path during its re-entry time.
'But if it had come down over a populated area there probably would be reports by now,' the astrophysicist, who tracks man-made space objects, said in a telephone interview.
Most parts of the satellite were expected to burn up as they hit the atmosphere, but up to 30 fragments weighing a total of 1.87 tonnes may have survived the re-entry, the German Aerospace Centre said.
Calculations based on U.S. military data indicate that debris of the ROSAT scientific research satellite must have crashed somewhere east of Sri Lanka over the Indian Ocean, or over the Andaman Sea off the coast of Myanmar, or further inland in Myanmar or as far inland as China, he said.
The satellite entered the atmosphere between 9:45pm to 10:15pm Saturday EDT and would have taken 15 minutes or less to hit the ground, the centre said.
Hours before the re-entry, the center said the satellite was not expected to land in Europe, Africa or Australia.
There were no immediate reports from Asian governments or space agencies about the fallen satellite, but an exact determination could take days.
Berlin: Scientists were trying to establish how and where a defunct German research satellite returned to the Earth on Sunday, after warning that some parts might survive re-entry and crash at up to 280 mph (450 kph).
There was no immediate solid evidence to determine above which continent or country the ROSAT scientific research satellite entered the atmosphere, said Andreas Schuetz, spokesman for the German Aerospace Centre.
Most parts of the minivan-sized satellite were expected to burn up, but up to 30 fragments weighing a total of 1.87 tons (1.7 metric tons) could crash.
Scientists were no longer able to communicate with the dead satellite and it must have traveled about 12,500 miles (20,000 kilometers) in the final 30 minutes before entering the atmosphere, Schuetz said.
Experts were waiting for "observations from around the world," he added.
Scientists said hours before the re-entry into the atmosphere that the satellite was not expected to hit over Europe, Africa or Australia. According to a precalculated path it could have been above Asia, possibly China, at the time of its re-entry, but Schuetz said he could not confirm that.
The 2.69-ton (2.4 metric ton) scientific ROSAT satellite was launched in 1990 and retired in 1999 after being used for research on black holes and neutron stars and performing the first all-sky survey of X-ray sources with an imaging telescope.
The largest single fragment of ROSAT that could hit into the earth is the telescope's heat-resistant mirror.
During its mission, the satellite orbited about 370 miles (600 kilometers) above the Earth's surface, but since its decommissioning it has lost altitude, circling at a distance of only 205 miles (330 kilometres) above ground in June for example, the agency said.
Even in the last days, the satellite still circled the planet every 90 minutes, making it hard to predict where on Earth it would eventually come down.
A dead NASA satellite fell into the southern Pacific Ocean last month, causing no damage, despite fears it would hit a populated area and cause damage or kill people.
Experts believe about two dozen metal pieces from the bus-sized satellite fell over a 500-mile (800-kilometre) span.
The German space agency puts the odds of somebody somewhere on Earth being hurt by its satellite at one in 2,000 - a slightly higher level of risk than was calculated for the NASA satellite. But any one individual's odds of being struck are one in 14 trillion, given there are 7 billion people on the planet.

The pic, which I found on i.imgur.com, says: Indians have the largest amount of black money in Swiss Banks. Rudolf Elmer provides the list of famous Indians to Wikileaks. He also revealed that black money was started depositing in Swiss Banks in early 70s by some of the names of India through illegal mining, stock market, drug dealing, fake projects etc.
According to the pic: Though Wikileaks has finally released few names, but it has threatened that if Indian government doesn’t start taking action, they would reveal all the names of big and powerfulpoliticians. See this pic carefully:

Please Note: I’m still unsure of these details since Wikileaks hasn’t published these details on their site.
As most of the Congress and UPA leaders only have been listed here so I doubt its authenticity and consider it as fake. It’s up to you, how you take it ! I shouldn’t be made responsible under any circumstances. I found this on Imgur so I pasted it.

It's déjà vu all over again, as Yogi Berra might have put it. This month, another defunct satellite is expected to plunge to Earth — offering us another welcome respite from worrying about our real problems.
Instead, we can worry about the fantastically slim odds of being killed by some of the debris that will be shed by Germany's ROentgen SATellite (ROSAT) X-Ray telescope on its fiery uncontrolled re-entry to Earth just before Halloween.
"It will not be possible to make any kind of reliable forecast about where the satellite will actually come down until about one or two hours before the fact," says the European Space Agency's Heiner Klinkrad, in a statement on the re-entry. "In the final phase, ROSAT will be 'caught' by the atmosphere at which point it will not even complete an orbit around the Earth: Instead, it will go into 'free fall'."

"In the final phase, ROSAT will be 'caught' by the atmosphere at which point it will not even complete an orbit around the Earth: Instead, it will go into 'free fall'."
During its mission, the ROentgen SATellite (ROSAT) performed its observations in an elliptical orbit at distances of between 585 and 565 kilometres above the surface of the Earth. Since its decommissioning, atmospheric drag has caused the satellite to lose altitude. In June 2011, it was at a distance of only about 327 kilometres above the ground. Due to the fact that ROSAT does not have a propulsion system on board, it was not possible to manoeuvre the satellite to perform a controlled re-entry at the end of its mission in 1999. When the spacecraft re-enters the atmosphere at a speed of approximately 28,000 kilometres per hour, the X-ray observatory will break up into fragments, some of which will burn up by the extreme heat. The latest studies reveal that it is possible that up to 30 individual pieces weighing a total of 1.7 tons may reach the surface of the Earth. The largest single fragment will probably be the telescope's mirror, which is very heat resistant and may weigh up to 1.7 tons.The time and location of re-entry cannot be predicted precisely. At present, scientists expect the X-ray satellite, which completes an orbit around Earth in about 90 minutes, to re-enter around between 21 and 24 October 2011. Currently, the re-entry date can only be calculated to within plus/minus two days. This time slot of uncertainty will be reduced as the date of re-entry approaches. However, even one day before re-entry, the estimate will only be accurate to within plus/minus five hours .All areas under the orbit of ROSAT, which extends to 53 degrees northern and southern latitude could be affected by its re-entry. The bulk of the debris will impact near the ground track of the satellite. However, isolated fragments could fall to Earth in a 80 kilometre wide path along the track.
Germany's defunct ROSAT satellite will fall back to Earth some time this week, but German space officials say the fall site is still a mystery. Re-entry is expected between Friday and Oct. 24.
"The time and location of re-entry cannot be predicted precisely," the German Aerospace Center (DLR) stated. It also noted that re-entry can be calculated only to within two days but certainty will grow as the date draws closer.
The scientists say that even a day before re-entry the estimate will only be accurate to within five hours.

Tricks: ROSAT: A German-American-British X-ray and ultraviolet astronomy satellite, named for Wilhelm Röntgen (1845–1923) who discovered X-rays; it operate...
In late October or early November a Germany astronomy satellite – called ROSAT- will plunge uncontrolled back to Earth.
Earth has been told to brace for a possible satellite collision as an orbiting telescope weighing nearly three tons has spun out of control and is plummeting homewards.
ROSAT, a German X-ray telescope built with British and American technology, has been orbiting the Earth since 1990 and has provided invaluable data on stars. But they lost contact with it in 1999.
It is now predicted to re-enter Earth's atmosphere at the end of this month.

A German-American-British X-ray and ultraviolet astronomy satellite, named for Wilhelm Röntgen (1845–1923) who discovered X-rays; it operated for almost nine years. The first six months of the mission were dedicated to an all-sky survey in X-rays (0.1–2.5 keV) and ultraviolet (62–206 eV) using an imaging telescope with a sensitivity about 1,000 times greater than that achievable with the instruments on Uhuru. During the subsequent pointed phase of its mission, ROSAT made deep observations of a wide variety of objects. Its operation ended in Feb. 12, 1999.The Roentgensatellit (ROSAT) was a joint German, US and British X-ray astrophysics project. ROSAT carried a German-built imaging X-ray Telescope (XRT) with three focal plane instruments: two German Position Sensitive Proportional Counters (PSPC) and the US-supplied High Resolution Imager (HRI). The X-ray mirror assembly was a grazing incidence four-fold nested Wolter I telescope with an 84-cm diameter aperture and 240-cm focal length. The angular resolution was <5 arcsec at half energy width. The XRT assembly was sensitive to X-rays between 0.1 to 2 keV.
In addition, a British-supplied extreme ultraviolet (XUV) telescope, the Wide Field Camera (WFC), was coaligned with the XRT and covers the wave band between and 6 angstroms (0.042 to 0.21 keV).
ROSAT's unique strengths were high spatial resolution, low-background, soft X-ray imaging for the study of the structure of low surface brightness features, and for low-resolution spectroscopy.
The ROSAT spacecraft was a three-axis stablized satellite which can be used for pointed observations, for slewing between targets, and for performing scanning observations on great circles perpendicular to the plane of the ecliptic. ROSAT was capable of fast slews (180 deg. in ~15 min.) which makes it possible to observe two targets on opposite hemispheres during each orbit. The pointing accuracy was 1 arcminute with stability <5 arcsec per sec and jitter radius of ~10 arcsec. Two CCD star sensors were used for optical position sensing of guide stars and attitude determination of the spacecraft. The post facto attitude determination accuracy was 6 arcsec.
The ROSAT mission was divided into two phases:
(1) After a two-month on-orbit calibration and verification period, an all-sky survey was performed for six months using the PSPC in the focus of XRT, and in two XUV bands using the WFC. The survey was carried out in the scan mode.
(2) The second phase consists of the remainder of the mission and was devoted to pointed observations of selected astrophysical sources. In ROSAT's pointed phase, observing time was allocated to Guest Investigators from all three participating countries through peer review of submitted proposals. ROSAT had a design life of 18 months, but was expected to operate beyond its nominal lifetime.
Re-entry into the Earth's atmosphere
In 1990, the satellite was put in an orbit at an altitude of 580 km and inclination of 53° . Since that time, due to atmospheric drag, the satellite has slowly lost height. As of September 2011, the satellite continues to orbit approximately 270 km above the Earth, and is expected to re-enter the Earth's atmosphere in October 2011.
NIFTY
It is the Sensex's counterpart on the National Stock Exchnage, NSE.
The only difference between the two indices (the Sensex and Nifty) is that the Nifty comprises of 50 companies and hence is more broad-based than the Sensex.
Having said that one must remember that the Sensex is the benchmark that represents Indian equity markets globally.
The Nifty 50 or the S&P CNX Nifty as the index is officially called has all the 30 Sensex stocks.

Each company has a weight assigned to it. Companies like Reliance, Infosys, and HLL have higher weightages compared to others like HDFC , Wipro, or a BHEL.
The increase or decrease in this index, the Sensex, is the effect of a corresponding increase or decrease in the stock market price of these 30 companies.
New Delhi, Oct 5 (ANI): Union Communications and Information Technology Minister Kapil Sibal launched 'Akash' a $35(The expected price tag is 1,750 rupees.) tablet here on Wednesday.
The government is buying the first units of the lightweight touch-screen device, called Aakash, or "sky" in Hindi, for $50 each from a British company which is assembling the web-enabled devices in India.
A pilot run of 100,000 units will be given to students for free, with the first 500 handed out at the launch to a mixed response. It supports video conferencing, has two USB ports and a three-hour battery life but some users said it was slow.
Two years in development, the paperback book-sized Aakash may help the government's goal of incorporating information technology in education, although critics were doubtful of its mass appeal.
