HISTORY OF COMPUTER DATA STORAGE A STAGE BY STAGE PICTORIAL PRESENTATION
From the beginning of mankind, man tried to find a way to store information for the following generations. When people nowadays hear the word storage or computer storage they normally think aboutCD Rom, USB key or DVD. Things like the floppy disk or the punch card are nearly forgotten. In fact, the history of information storage goes back to pre-historic times where mankind used red and yellow ochre, hematite, manganese oxide and charcoal to paint information about their life on rock walls, caves and ceilings.
Nowadays we are used to having hundreds of gigabytes of storage capacity in our computers. Even tiny MP3 players and other handheld devices usually have several gigabytes of storage. This was pure science fiction only a few decades ago. For example, the first hard disk drive to have gigabyte capacity was as big as a refrigerator, and that was in 1980. Not so long ago!
Pingdom stores a lot of monitoring data every single day, and considering how much we take today’s storage capacity for granted, it’s interesting to look back and get things in perspective. Here is a look back at some interesting storage devices from the early computer era.
Above: The 1024-bit Selectron
The Selectron tube
The Selectron tube had a capacity of 256 to 4096 bits (32 to 512 bytes). The 4096-bit Selectron was 10 inches long and 3 inches wide. Originally developed in 1946, the memory storage device proved expensive and suffered from production problems, so it never became a success.

APPLE GOING TO DEVELOP HYDROGEN FUEL BATTERY FOR THEIR PRODUCTS
A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent.Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like Methanol are sometimes used. Fuel cells are different from batteries in that they require a constant source of fuel and oxygen to run, but they can produce electricity continually for as long as these inputs are supplied. Apple give application for their Patents at U.S PATENT AND TRADE MARK office for Two Patents Related To Hydrogen Fuel Cells reports said that this may be the starting point for hydrogen fuel cells

NASA confirms 'Super-Earth' that could hold life
WASHINGTON: In another step toward finding Earth-like planets that may hold life, NASA has said the Kepler space telescope has confirmed its first-ever planet in a habitable zone outside our solar system.
French astronomers earlier this year confirmed the first rocky exoplanet to meet key requirements for sustaining life. But Kepler-22b, initially glimpsed in 2009, is the first the US space agency has been able to confirm.
Confirmation means that astronomers have seen it crossing in front of its star three times. But it doesn't mean that astronomers know whether life actually exists there, simply that the conditions are right.
Such planets have the right distance from their star to support water, plus a suitable temperature and atmosphere to support life.
'We have now got good planet confirmation with Kepler-22b,' said Bill Borucki, Kepler principal investigator at NASA Ames Research Center.
'We are certain that it is in the habitable zone and if it has a surface, it ought to have a nice temperature,' he told reporters on Monday.
Spinning around its star some 600 light years away, Kepler-22b is 2.4 times the size of the Earth, putting it in class known as 'super-Earths,' and orbits its Sun-like star every 290 days.
Its near-surface temperature is presumed to be about 72 degrees 22 Celsius. Scientists do not know, however, whether the planet is rocky, gaseous or liquid.
The planet's first 'transit,' or star crossover, was captured shortly after NASA launched its Kepler spacecraft in March 2009.
NASA also announced that Kepler has uncovered 1,094 more potential planets, twice the number it previously had been tracking, according to research being presented at a conference in California this week.
Kepler is NASA's first mission in search of Earth-like planets orbiting suns similar to ours, and cost the US space agency about USD 600 million.
It is equipped with the largest camera ever sent into space -- a 95-megapixel array of charge-coupled devices -- and is expected to continue sending information back to Earth until at least November 2012.
Kepler is searching for planets as small as Earth, including those orbiting stars in a warm, habitable zone where liquid water could exist on the surface of the planet.
The latest confirmed exoplanet that could support life brings to three the total number confirmed by global astronomers.

Mammoth To Be Brought Back To Life In Five Years
The woolly mammoth, which became extinct 10,000 years ago, will now be brought back to life from a cloned bone marrow within five years, scientists have claimed.
The researchers say it may be possible to clone a woolly mammoth after they found a well-preserved bone marrow in a thigh bone recovered in Siberia.
By replacing the nuclei of egg cells from an elephant with those taken from the mammoth's marrow cells, embryos with mammoth DNA can be produced.
The embryos will be planted into elephant wombs for delivery as the two species are close relatives.
For scientists involved in research since the 1990s, finding nuclei with undamaged mammoth genes has been a challenge.
Many areas in eastern Russia -- that usually remains frozen -- thawed leading to the discovery of a number of frozen mammoths, the report said.
Scientists from Russia's Sakha republic's mammoth museum and Japan's Kinki University will launch a joint research in 2012 in a bid to recreate the giant animal, the Daily Mail reported citing Kyodo News.

It tops a new list of moons and planets most likely to harbour life. The researchers also found a planet called Gliese 581g, part of the Libra constellation, is the most similar to Earth - despite being 123 billion miles away.
It could support humans if mankind moves into outer space, as British genius Stephen Hawking has suggested.

ATTENTION HIDDEN CAMERAS AROUND'S:CHECK OUT ALL KIND OF HIDDEN CAMERAS
A hidden camera is a still or video camera used to film people without their knowledge. The camera is "hidden" because it is either not visible to the subject being filmed, or is disguised as another object. Hidden cameras have become popular for household surveillance, and can be built into common household objects such as smoke detectors, clock radios, motion detectors, ball caps, plants, and cellphones. Hidden cameras may also be used commercially or industrially as security cameras
But Nowadays Hidden cameras create too many problems
The next time you try on clothes at a department store, pay attention to the door.
A 10 News undercover investigation revealed customers may be revealing more than expected at Macy's stores all across the country. While it's illegal to secretly videotape inside fitting rooms in Florida, Macy's manages its loss-prevention by installing their privacy doors backward.
That means that any employee - or customer - standing up against the door can see inside. But the person getting changed cannot see out..

Scientists warn of possible peril from 2013 solar flare activity
Earlier this week, scientists attending the Electric Infrastructure Security Council conference in London warned that a massive solar flare may trigger global chaos by causing blackouts and wrecking satellite communications.
Solar flares are large explosions on the surface of the Sun, powered by the sudden release of magnetic energy that has built up in the Sun's atmosphere. They can last just a few seconds or up to an hour, and can occur in smaller intensities as often as several times per day.
The researchers say that this potential disaster could occur within three years, which is when astronomers forecast a peak in the Sun's magnetic energy cycle. They say that the resulting solar storm could potentially cause geomagnetic mayhem on earth, knocking out electricity grids around the world.
'As that magnetic field gets tangled up it gets more and more energetic, and that leads to an eleven year cycle of activity,' explained Chris Davis, a scientist on the Solar Stormwatch project at the British Royal Observatory, in an interview with Deutsche Welle.
'We're on a low level of activity at the moment but sunspots are starting to appear again, and spots are the manifestation of this magnetic field poking through the surface of the Sun.'
Previous large solar ejection occured in 19th century
Astronomers say that the current cycle of solar flare activity started around 2001 and they expect it to reach a peak sometime in 2013. But what's different about this peak is that it could be quite devastating.
The coronal mass ejection could release large amounts of matter, intense magnetic fields and other radiation into space. Typically, some scientists say, ejections of this size only occur approximately every 150 years � the last one was in 1859.
'The world's skies were bathed in a blood red aurora � the Northern and the Southern lights,' said Stuart Clark, a British astronomy journalist and author of 'The Sun Kings', which details the event and its impact on modern astronomy.
'And at the same time as these lights appeared in the sky, the nineteenth century equivalent of global communications and navigation just completely stopped working.'
In other words, Clark explained, compasses spun uselessly and the telegraph � cutting-edge technology at the time � crashed.
Solar flares have disrupted power transmission before
Today, given that the 21st century relies so heavily on other technology like communications and entertainment satellites, the world is more at risk from damage caused by high-energy particles and other disturbances, said Avi Schnurr, who organized the conference. He is a former US Department of Defense analyst, and current executive director of the Israel Missile Defense Association, a lobbying organization.
In addition to affecting spacecraft, such magnetic storms can affect power transmission behavior on the Earth, because they cause 'transformer saturation,' which reduces or distorts voltage. That could mean the disruption of power plants and transmission stations, which happened in the province of Quebec in Canada during a solar flare in 1989.
'The electric grids when they go down, they bring with them our capability to produce water and send water to homes, to produce food, communications, medical care. All the things we depend on.' Schnurr said. 'And if it's down for months or years, it's very painful to think what that would mean.'
Other scientists say threat is 'overstated'
But not all scientists are convinced of this high level of damage that a solar ejection would cause to the Earth in 2013.
In an interview published Friday with the Australian Broadcasting Corporation (ABC), Phil Wilkinson, the assistant director of the Australian Bureau of Meteorology's Ionospheric Prediction Service, said that the claims that this solar maximum would be the most violent in 100 years are 'overstated.'
'[It's] going far beyond what's realistic and could be worrying or concerning for people who don't really understand the underlying science behind it all,' he said. 'The real message should be that the coming solar maximum period could be equally as hazardous as any other solar maximum.'
He also said that the impact on power grids would be minimal.
'At worst, it's a regional thing, not a global thing as these reports imply,' he added.
Infrastructure could be protected by 'huge surge protectors'
However, Schnurr also said that protecting infrastructure both on the ground and in space is a matter of politics and money.
'We do need to get it together for the governments involved to start protecting the electric grids,' he said. 'But it turns out there are fairly simple measures which are well understood now which can be taken. There are the equivalents of huge surge protectors which need to be put on these different transformers.'
This 'equivalent' is known as a residual current device, or RCD, which is used for domestic wiring systems. These are trip switches installed on electricity transmission lines that break the connection when there's a sudden voltage increase.
There would be a temporary disruption in power, but the transformers themselves would be protected. RCDs, Schnurr explained, are roughly analogous to surge protectors used in ordinary homes to protect electronic devices from overloading.
He also said that the cost of installing such preventive measures is relatively inexpensive to governments � in the United Kingdom, it would cost a few hundred million dollars.
But with so many governments slashing their budgets in the United States, Europe and around the globe, it's still not clear whether governments will actually spend money on an event of which the consequences are not predicted with 100 percent certainty.
After all, similar warnings were made over the Y2K bug, the massive worldwide computer glitch, that seemed to be overblown. Still, Stuart Clark said that governments cannot afford to ignore these warnings.
'The consequences if this does happen are just unbelievable,' he said. 'The loss of the power grid for years, loss of the ability to perform any kind of finance or electronic transfers or anything like that, if we don't do anything to protect ourselves now.
