Understanding The Symbian OS



Symbian OS
is one of Nokia's mobile operating systems for mobile devices, originally developed by Symbian Ltd.

It is a descendant of Psion's EPOC and runs exclusively on ARM processors. The OS was renamed Symbian OS and was envisioned as the base for a new range of smartphones. This release is sometimes called ER6. Psion gave 130 key staff to the new company and retained a 31% shareholding in the spun-out business. The first 'open' Symbian OS phone, the Nokia 9210 Communicator, was released in June 2001

Symbian OS was created with three systems design principles in mind:

  • the integrity and security of user data is paramount,
  • user time must not be wasted, and
  • all resources are scarce.

Series 40

Series 40 is a software platform and application user interface (UI) software on Nokia's broad range of mid-tier mobile phones, as well as on the Vertu line of luxury phones. It is the world's most widely used mobile phone platform and found in hundreds of millions of devices.

How Does a Subwoofer Work???


A subwoofer is essentially a speaker that is designed to play the lowest bass frequencies replicated by your stereo system. Regular speakers reproduce a wide frequency range but often lack the deepest bass frequencies. A subwoofer uses a larger woofer as well as a built-in amplifier that powers the signal to provide deeper, cleaner bass.

Most subwoofers are powered, meaning they require their own individual power supply from an electrical outlet to power a built-in amplifier. Passive subwoofers do not require their own dedicated power supply and use power from the receiver's amplifier.
Subwoofers are connected to an audio receiver or preamplifier. The receiver sends low frequency (usually 20 Hz to 100 Hz) signals, refered to on soundtracks as low frequency effects (LFE), via electrical current to the subwoofer. The subwoofer amplifies the current and converts it to sound through the use of a magnetic coil that causes vibration of the driver's cone. This vibration results in low frequency sound waves being sent out through the air.

Low frequency signals are not directional the way higher frequencies are. This means that the listener has more flexibility in the placement of the subwoofer, unlike the left and right speakers which are very sensitive to placement and generally need to be directed at the listening position. A subwoofer can be moved around based upon the layout of the room. Experimentation with different positioning can also help to ascertain the best location for sound quality.

What Do You Know About Kochi???



  • There have been controversies about the origin of the name 'Cochin'. Some people attribute the name to the Malayalam word 'Kochazhi' or 'Small Sea', while others think Cochin was named after China when traders from the court of Kublai Khan of China, visited Cochin and gave it the name of their homeland. The local people refer to Cochin as Kochi, and this is the city's official name today.

  • At the beginning of the 20th century a modern port with dry docks and ship repair yards was constructed, and Willingdon Island (connecting Fort Cochin with Ernakulam and other townships by a Rail Bridge and road) was built from the dredging of the harbor's inner channels.


  • The earliest known ruling dynasty of Cochin was the Cheras, who had their capital at Cranganore (modern day Kodungallur).

  • This port city was, as the ancient Italian traveler Pliny called it, the "primus emporium India" or the major gateway of India, the position Mumbai enjoys today.
  • St. Thomas, an apostle of Christ brought Christianity here as early as 52 CE.


  • St Thomas established the first church in India at Malayatoor, 35 kilometers from present day Cochin City.


  • Malik ibn Dinar introduced Islam here even before it had been firmly established in all Arabia.


  • The first mosque in India is at Kodungallur, on the roadside of National Highway 17.


  • In fact, the last Chera King, Cheruman Perumal, embraced Islam, proceeded to Makkah on pilgrimage, and died there His grave still exists in Salalah, Oman.

  • The geographical layout Cochin city as we know it today traces back to the great flood of 1341 CE, caused by a tsunami triggered by a gigantic undersea volcanic eruption. During this year the river Periyar flooded like never before (or after), and changed its course. The hitherto flourishing port of Cranganore silted up from the mud up-stream.


  • A 15th century Italian traveler, Nicolo Conti remarked - "China is a good place to make money, and Cochin to spend it at".


  • Vasco da Gama landed in Calicut in 1498.


  • Legend holds that the Jews first settled in India during the time of King Solomon, when there was trade in teak, ivory, spices and peacocks between the Land of Israel and the Malabar Coast, where Cochin is located.

2012 (The World's End) : Myth Or Fact - Plague (my private investigation)

What we have not tamed yet and will not be taming in the near future, in the world is the ancient species of microbes that are spread all around us. Just in the last year there have been reports of 24 different types of flues. The UN have let out notices of the huge threat that mankind may face due to the microbes. With the modern day irregular life style, it will just get worse..



For over 200 years plague raged in the Mediterranean countries and claimed lives of at least 45 million people

Nobody knows when plague appeared. Experts say that plague pestholes still exist in remote parts of Central Asia and some South African countries, Namibia, Angola and South African Republic. And supposedly, the disease had its sources right on these territories. Long ago researchers determined that the plague bacillus lives in organisms of wild rodents and is carried by fleas. But it was just in the mid-1980s that researchers managed to say how an epidemic breaks out. As it turned out, plague pandemic breaks out because of drought. Hungry, weak and diseased rodents abandon their native places in search of food and thus spread plague over vast territories. Sooner or later they reach human habitation. Fleas infected with plague bacilli cling to domestic rodents for which plague turns to be fatal. Then, fleas jump on dogs, cats and humans.


This exchange of the infection is particularly dangerous for people. Just few percent of diseased people survived in the epochs when mankind knew no insecticides or antibiotics. It is believed that the first plague epidemic that left reliable evidence broke out in the 12th century B.C. Old Testament mentions mice that spoiled the ground.


Another plague epidemic gripped all countries of the civilized world and thus was called a pandemic; it came to the Upper Nile from Central Africa in 541. The plague killed thousands of people and reached Alexandria of Egypt, a busy port where tens of merchant vessels dropped anchor every day. Alexandria granaries were packed with grain and certainly there were flocks of rats. This fact predetermined the history of Europe for many centuries ahead. For less than a year plague reached Constantinople where 10,000 people died every day at the epidemic peak. Plague made the Byzantine Empire vulnerable to aggressive neighbors and became the reason of its subsequent extinction.

For over 200 years plague raged in the Mediterranean countries and claimed lives of at least 45 million people. Fourteen outbursts of plague on vast territories were registered over the period. But then plague mysteriously disappeared all of a sudden. So, when plague reappeared in 1346 people did not remember the fatal disease and believed they were facing the doomsday.

2012 (The World's End) :Global Warming (my private investigation)

The movie 2012 was pretty amazing and scientific. But in order to make a movie and to make people believe of it as a movie, many facts and scientific explanations was made hidden. This topic deals with the global warming that may lead to a flood or something like that was shown in the movie.

We all know what global warming is and what effect it will cause on us. But getting into details I think it needs an explanation. In the winter of 2005 scientists made a frightening discovery. Increasing global temperature were causing the Greenland ice shield to melt in a alarming rate. The scientists discovered that the sudden melting of these ice shields may prove to be catastrophic.


This may cause a sudden rise in the sea level, about 20ft. Can you imagine that?. Almost all the land masses will be under water. China and Bangladesh is going to get the effect in the most devastating manner and before all others. Then the world will see the biggest ever emigration of people but to nowhere. We cant hide from this no-matter which country we are in.
The remaining land will be gripped by a different kind of water crisis. In the west of the globe 75% of the water comes from the snow pack. As this is no longer available there will be a huge water crisis. Water crisis leads to food crisis. This leads people to turn onto each other, Yes, I mean what i said. There has been such cases of food shortage and people turning into Cannibalism.


It will be the time when we are going to recognize that money is northing. Even money wont be able to fulfill your hunger. There are many examples in the world where wars broke out because of water. Food, water and air and the necessary components for our existence in the earth. Just thinking of these three components, are they safe?? The answer is no, Water is being polluted and air is being polluted. So the third one the food depends on these two. So why do we believe that we are safe?? Wars, Famine and drought may lead us to extinction in the near future, and this sentence is not a joke. The Generation where we are living is the only generation that can control the faith of the planet Earth. So I am not saying that now it is the time to act. It has been high-time that we act.

2012 (The World's End) : Myth Or Fact - Nuclear Wars (my private investigation)

Humans are the worst threat to themselves. On the path of our development we have left behind many scars, on planet Earth. When we consider this as a threat we have a lot to worry about. But the threat that we are creating for ourself is far beyond imagination. J. Robert Oppenheimer, the father of the Atomic Bomb, when he saw the worst effects that it can bring to the world, repented about his findings. He blamed himself as the "Destroyer of worlds".



The nuclear weapons are denoted as taking a part of sun and duplicating it on earth. Yes this finding was a turning point in the history of man's position in the earth. Now he possess the power to destroy the whole earth and he living beings in it. The technology that powered everything in the earth, the sun, has now been practically duplicated on earth!!. It was an amazing achievement, but it carried with it, tremendous danger!!. Now the question is that can we control..what we have created??.

The following is a list of nations that have admitted the possession of nuclear weapons, and the approximate number of warheads under their control. This list is informally known in global politics as the "Nuclear Club".

United States - 10,640
Russia - 8,600
People's Republic of China - 400
France - 350
United Kingdom - 200
India - 60-90
Pakistan - 24-48

What are the immediate and lingering effects of a nuclear blast?

Nuclear explosions produce both immediate and delayed destructive effects. Immediate effects (blast and shockwave, radiation) are produced and cause significant destruction within seconds or minutes of a nuclear detonation. The delayed and lingering effects (radioactive fallout and other possible environmental contamination) inflict damage over an extended period ranging from hours to centuries.


(The mushroom cloud of the atomic bombing of strategic port city, Nagasaki, in 1945 lifted nuclear fallout some 60,000 feet (18 km) above the epicenter.)
The missile or method of deployment would be detonated slightly above the ground, to extend the shockwave over the desired target, and maximize the bombs effect. The first chain of events would be the heat and extreme light, scorching everything for a few mile radius (depending on the size) in nearly 20,000°F flames. The air itself would literally be sucked up, and seem to catch fire. Seconds after the initial impact, the shockwave would follow. This would level buildings, homes, and throw cars around like paper in the wind. Imagine having a hurricane made of fire, trees discintigrate in the hot wind, and structures crumble like dust. The shockwave would be so powerful that the air would not be able to absorb it all. Some energy would create an EMP


(Electro-Magnetic Pulse) that would destroy electrical circuits miles from ground zero, perhaps even knocking out orbiting satellites.
After the explosion itself, anyone on the edge of the explosion (who were lucky enough to survive) would have melted flesh and severe burns, the skin would literally fall off the bone. Anyone who had seen the blast from such a distance would have permanent loss of vision.
In the days, weeks and months to follow, anyone exposed to the area around ground zero would begin to suffer the effects of radiation and nuclear fallout. It would - and has been an awful sight to see.
