K2 is the second-highest mountain on Earth, after Mount Everest. With a peak elevation of 8,611 m (28,251 feet), K2 is part of the Karakoram Range, and is located on the border between Gilgit, in Gilgit-Baltistan of Pakistan and the Taxkorgan Tajik Autonomous County of Xinjiang, China. It is more hazardous to reach K2 from the Chinese side thus, it is mostly climbed from the Pakistani side.

K2 is known as the Savage Mountain due to the difficulty of ascent and the second-highest fatality rate among the "eight thousanders" for those who climb it. For every four people who have reached the summit, one has died trying. Unlike Annapurna, the mountain with the highest fatality rate, K2 has never been climbed in winter.


World’s Fastest Supercomputer-Tianhe

Tianhe-I, Tianhe-1, or TH-1 , in English, "Milky Way (literally, Sky River) Number One", is a supercomputer capable of an Rmax (maximum range) of 2.566 petaFLOPS; that is, over 2½ quadrillion (thousand million million) floating point operations per second, or FLOPS. Located at the National Supercomputing Center in Tianjin, China, it was the fastest computer in the world from October 2010 to June 2011 and is one of the few Petascale supercomputers in the world.

In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.507 petaFLOPS. In June 2011 the Tianhe-1A was overtaken by the K computer as the world's fastest supercomputer.
In October 2010, Tianhe-1A, an upgraded supercomputer, was unveiled at HPC 2010 China. It is now equipped with 14,336 Xeon X5670 processors and 7,168 Nvidia Tesla M2050 general purpose GPUs. 2,048 NUDT FT1000 heterogeneous processors are also installed in the system, but their computing power was not counted into the machine's official Linpack statistics as of October 2010. Tianhe-1A has a theoretical peak performance of 4.701 petaflops. NVIDIA suggests that it would have taken "50,000 CPUs and twice as much floor space to deliver the same performance using CPUs alone." The current heterogeneous system consumes 4.04 megawatts compared to over 12 megawatts had it been built only with CPUs.

The Tianhe-1A system is composed of 112 computer cabinets, 12 storage cabinets, 6 communications cabinets, and 8 I/O cabinets. Each computer cabinet is composed of four frames, with each frame containing eight blades, plus a 16-port switching board. Each blade is composed of two computer nodes, with each computer node containing two Xeon X5670 6-core processors and one Nvidia M2050 GPU processor. The system has 3584 total blades containing 7168 GPUs, and 14,336 CPUs, managed by the SLURM job scheduler.[18] The total disk storage of the systems is 2 Petabytes implemented as a Lustre clustered file system,and the total memory size of the system is 262 Terabytes.

Another significant reason for the increased performance of the upgraded Tianhe-1A system is the Chinese-designed NUDT custom designed proprietary high-speed interconnect called Arch that runs at 160 Gbps, twice the bandwidth of InfiniBand.

The supercomputer is installed at the National Supercomputing Center, Tianjin, and is used to carry out computations for petroleum exploration and aircraft design. It is an "open access" computer, meaning it provides services for other countries. The supercomputer will be available to international clients.

The computer had cost $88 million to build and around $20 million annually for costs involving energy intake and operating costs. It also has to have 200 workers in order to have it operate and function properly.

Tianhe-IA is ranked as the world's second fastest supercomputer in the TOP500 list

Temporary Marriage in Iran


Anonymous in the West, temporary marriage is, basically, a contractual deal between a man and a woman who decide to be married for an agreed period of time varying from one hour to 99 years. This custom is practiced among the Shiites of Iran and Iraq, although not a part of Quranic teachings. In Iran, a man - bachelor or married, and a woman - virgin, divorced, or widowed, can, at any time enter into a temporary marriage contract, commonly known as sigheh or nekah-e-monghate'e.

In a temporary marriage contract, no registration or witness is required. As per the proponents of this arrangement, it is considered as a means of curbing free sex and control prostitution. Also, the arrangement allows a man to have 'sigheh' wives to an extent that is affordable by him. But a woman, on the other hand, is allowed to enter only one such relationship at a point of time. Moreover, the woman is also paid the compensation amount before entering the contract.

However, no couple can enter another contract before completing a waiting period of three months or an elapse of two menstrual cycles. This waiting period is referred as 'edda'. The trend of temporary marriage is, conversely, not liked by the educated middle class families. Also, some women are predisposed to think it as legal prostitution and, therefore, oppose the trend. This trend is, therefore, practiced more commonly by women who are either divorced or widowed. Additionally, the trend is also popular among theological seminaries and the clergy.

Ever heard of LPG Cylinder's expiry Date ?

Do you know that there is an expiry date (physical life) for LPG cylinders? Expired Cylinders are not safe for use and may cause accidents. In this regard, please be cautious at the time of accepting any LPG cylinder from the vendor.
Here is how we can check the expiry of LPG cylinders:
On one of three side stems of the cylinder, the expiry date is coded alpha numerically as follows A or B or C or D and some two digit number following this e.g. D06.
The alphabets stand for quarters -
1. A for March (First Quarter),
2. B for June (Second Quarter),
3. C for Sept (Third Quarter),
4. D for December (Fourth Quarter).

The digits stand for the year till it is valid. Hence D06 would mean December Quarter of 2006.
Please Return Back the Cylinder that you get with a Expiry Date, they are prone to Leak and other Hazardous accidents

The second example with D13 allows the cylinder to be in use until Dec 2013.

Solar City Tower,Rio de Janeiro



Solar City Tower,built atop the island of Cotonduba will be the welcome symbol to the 2016 Olympic Games in  Rio de Janeiro.It will be seen by the game visitors and participants as they arrive by air or water.

The tower, captures solar energy. It will supply energy for all of the Olympic city, as well as also for part of Rio.It pumps up water from the ocean to create what appears like a water fall and this fall stimulates turbines that produce energy during the night.

Solar City Tower will be the point of reference for the 2016 Olympic Games in  Rio de Janeiro.

In 2020 We Can Wear Sony Computers On Our Wrist



Our present need for internet connectivity is so profound that secondary devices like the Nextep Computer are bound to happen. Developed to be worn as a bracelet, this computer concept is constructed out of a flexible OLED touchscreen. Earmarked for the year 2020, features like a holographic projector (for screen), pull-out extra keyboard panels and social networking compatibility, make the concept plausible. Ten years from now is not too far away, so how many of you think we’d be buying such gadgets?

Wikipedia says, Rajiv Gandhi’s Family has $18.66 billion in Swiss Bank accounts


According to the article, Swiss magazine Schweizer Illustrierte on 11 November 1991 revealed that Sonia Gandhi was controlling secret Swiss Bank accounts worth $2.2 billion (Rs 10,000 crore).

If these reports are true then India is in bigger trouble, you might have ever imagined. As, there are so many Indian politicians who are supposed to have bank accounts in Swiss Bank.

Even if 20% of them are having bank accounts, still there would be billions of dollars of India rotting in Swiss Bank.


In 1991, The effects of License Raj, reached a Flash Point.
India's fiscal deficit was 8.5 percent of GDP. The country faced a huge Balance of Payments crisis.
and was heading towards a default, and the Reserve Bank refused additional credit.
India had to mortgage its gold deposits to raise money from IMF.
In other words, Indian Economy stared at Bankruptcy.
Foreign reserves barely amounted to $ 1 billion. (only worth one weeks of Import)


Here is the proof of Black money of sonia. it was around 13000 CRORES (2.5 Billion swiss Franc) in the year 1991 in secret acount of swiss bank. This article was published under the  heading of "DIE Schweizer Konten der Diktatorane",in a Swiss magazine "SCHWEIZER ILLUSTRIETE"in 11th  Nov  1991 issue. It was showing amount diposited in secret accounts by different dictaters and currupt political leaders of world. The name and picture of late PM Mr Rajiv Gandhi can be very  much seen.
