Internet population many times greater than world population

 global-thumbInternet is growing in dimensions every second, so much so that there are more addresses than there are people on Earth, claims the team behind Microsoft’s new search engine Bing. Bing has put the number of web pages at “over 1 trillion”, while Google had earlier indexed more than one trillion discreet web addresses.

The current global population stands at more than 6.7 billion, which means that there are about 150 web addresses per person in the world. And this could mean that if a person spent just one minute reading every website in existence, then he or she would be kept busy for 31,000 years, without any sleep.

“An average person would need six hundred thousand decades of nonstop reading to read through the information,” News.com.au quoted Bing as saying. Mark Higginson, director of analytics for Nielsen Online, said that the global online population had jumped 16 per cent since last year.

“Approximately 1.46 billion people worldwide now use the internet which represents a solid 16 per cent increase from the previous year’s estimate (1.26 billion in 2007),” he said.

The largest Internet population belongs to China, with 338 million users online, which is more than there were people in the US. However InternetWorldStats.com (IWS), a website that combines multiple data sources, has claimed that China’s online population is more like 298 million.

“With the rates of India and China still quite low, there is ample room for growth in the coming decade,” said Higginson. But, measuring the online population could be tricky-there are servers, users, per capita numbers, and penetration percentages to evaluate. And thus it is difficult to find a single figure to represent the world online population.

IWS combined data from the UN’s International Telecommunications Union, Nielsen Online, GfK and US Census Bureau, and its latest global figures puts the number of internet users in the world at 1,596,270,108. And this is just 23.8 per cent of the estimated 6,0706,993,152 people in the world. But it changes every day.

“In terms of the future, we anticipate mobile to contribute significantly to internet usage,” said Higginson.

According to IWS, the top 5 countries with the most internet users are:

1 – China (298,000,000 users, or 22.4 percent of their population)

2 – US   (227,190,989, or 74.7 percent)

3 – Japan (94,000,000, or 73.8 percent)

4 – India (81,000,000, or 7.1 percent)

5 – Brazil (67,510,400, or 34.4% percent)

The Perfect Present?

gift-certificateBirthdays, Festivals, Marriage Anniversaries…what do these remind one of? Yes, you thought right, Gifts! We all have found ourselves not once, not twice but several times looking for gifts to present our loved ones with on various occasions. Always, we try to present something different, something unique yet something useful, in other words the ‘Perfect Present’. We want the gifts presented by us to be the best, to be first class and also low on the pocket. Well, now we have an easy option – A prepaid gift card

 Fashioned after a gift voucher and a debit card, a prepaid gift card is worth a fixed sum of money and can be swiped at any store. The value or the amount loaded on is entirely up to you. 

A gift card can be used multiple times at various stores until the amount loaded is exhausted. It is unique in terms of the flexibility it gives to the user in relation to what they can shop for and most importantly where they can shop for. Another advantage it offers is that one can check the amount left in it at any ATM centre.

However, a gift card may be used for purchases only and cash cannot be withdrawn.

Also, the card cannot be topped up again – meaning once the amount loaded is exhausted, one cannot load more money onto the same card.

 These cards come with an expiry date, which range from 5 months to a year, depending on the bank which issues it. If there is any amount left after the expiry date, the banks usually return the amount after deducting bank charges. However, banks impose a specific time period after the date of expiry within which the card must be returned in order to collect the balance. And in case, if the amount is exhausted before the expiry date, the card must be simply returned to the bank.

Till now, we have only seen how the card can be used if we are the receivers. Now, the question of purchasing the card arises. Not all banks offer this system of prepaid gift cards. Infact, there are only a handful which do so, namely, HDFC, IDBI, SBI, ICICI, IndusInd Bank and a few others.

However, one can buy the card from the bank at a fee ranging from Rs.100 to Rs. 200, even if one does not hold an account in the bank. (Some banks charge 1% of the amount loaded if the value of the gift card is more than Rs.10, 000.)

I hope this piece of news makes things easier for you, my dear reader as, instead of searching for gifts for hours together, one can now gift these pre-paid gift cards and also give the receiver a choice to select gifts for themselves and buying it from stores they prefer.

Tackle global warming?

The accidental discovery of a bowl-shaped molecule that pulls carbon dioxide out of the air paves the way for exciting new possibilities to deal with global warming.

These possibilities include genetically engineering microbes to manufacture those carbon dioxide “catchers” said JA Tossell, a Maryland University scientist who led the study. He noted that another scientist discovered the molecule while doing research unrelated to global climate change. These findings are slated for publication next month.

New fuel of the New era

510_03131337bransleskolan1In this era, when we all are dependent upon exhaustible fossil fuels for transport, Lars Stenmark of Uppsala University (Sweden) has come up with a green alternative – Hydrogen balls. He believes that by storing hydrogen gas in small balls, we can overcome the risk of fires and explosions as storing the gas in a spherical form, will help it to withstand twice the pressure that a cylindrical form can. If the car crashes and the tank breaks, the hydrogen-filled balls would just spread out and roll away and the gas from any broken balls would simply seep out and disappear into the atmosphere, thus causing no harm to the environment.

So do you all agree with him? Can small ping-pong balls replace our fossil fuels and help us save the environment from further harm? Think about it.

Technology used to cut down use of technology.

abrn244lAfter reading the title of my blog post, you may wonder how technology can be used to cut down use of technology. Well, this has occurred. Researchers at the University of Utah have found or rather invented a car key that prevents mobile use while driving. Isn’t technology being used to prevent mobile usage to reduce the number of road accidents?

This cost-effective solution to improve driving safety has been aptly named: ‘Key2SafeDriving’. The system includes a device that encloses a car key (which could be used by more members of a family). The device connects wirelessly with each key user’s mobile via either Bluetooth or RFID (radio-frequency identification) technologies. And when the engine is turned on with the automobile ignition key, a message is sent to the driver’s mobile, placing it in ‘driving mode’ and displaying a ‘stop’ sign on the phone’s display screen.

While in driving mode, users cannot use their mobiles to talk or send text messages, except for calling emergency nos. Researchers have also taken care of incoming calls which will be automatically answered with a message saying ‘I am driving now. I will call you later when I arrive at the destination safely’.

Turn your car’s waste heat into energy

Scientists Produce New Thermoelectric Substance That Can Increase Mileage By 5-10%


Washington: A Northwestern University-led research team has identified a promising new material that could efficiently convert waste heat into electricity to help power cars and improve gas mileage.

The researchers discovered that adding two metals, antimony and lead, to the well-known semiconductor lead-telluride, produces a thermoelectric material that is found to be more efficient at high temperatures than existing materials.  “We cannot explain this 100%, but it gives us a new mechanism — and probably new science — to focus on as we try to raise the efficiency of thermoelectrics,” said Mercouri Kanatzidis, Charles and Emma Morrison Professor of Chemistry in the Weinberg College of Arts and Sciences.

Current thermoelectric technology is only used in niche markets, such as solid-state refrigeration and cooling, because the materials are not very efficient.
With new materials and increased efficiency, devices based on thermoelectrics could find widespread use in the automotive industry, solar energy conversion and the conversion of waste heat from nuclear reactors, smokestacks and industrial equipment.

“It’s a big accomplishment to recover some of the heat or energy that would otherwise be lost and convert it into useful energy,” said Kanatzidis. “That’s what thermoelectrics can do, but we need to make them more efficient to really be practical,” he added.
A thermoelectric device, for example, could be attached to a car’s tailpipe. The side of the material in contact with the tailpipe would be the hot side, and the side exposed to the air would be the cold side. The temperature difference would be enough to generate electricity, which would be returned to the car’s engine for additional torque. Such devices also could be used in large industrial plants, such as those for power, chemical production and glass making. Researchers hope to raise mileage by 5 to 10% per gallon using thermoelectrics, which would be significant.

Google Chrome

Google Inc, creator of the world’s most popular internet search engine is all set to further solidify its position in the software industry by introducing ‘Google Chrome’, its own web browser, challenging Microsoft Corp’s dominant Internet Explorer.

Let us the features of Chrome as announced by Google through a comic drawn by Scott McCloud, creator of the classic Understanding Comics.

* Chrome, Google’s open-source browser includes Google’s Gear project and also a powerful JavaScript engine, called V8, to run the next generation of web applications.

* Chrome, uses special tabs unlike those of Firefox and places them on the upper side of the windows and not below the address bar.

* The browser has an address bar, called, omnibox with auto-completion features.

* As a default homepage, Chrome has a ‘speed-dial’ feature which enables the user to view his/her most visited web pages as nine screenshot thumbnails and to the side, the user can view a couple of his recent searches, recently bookmarked pages and also recently closed tabs.

* Google Chrome also helps the user to create an ‘incognito’ window and nothing that occurs in that window is ever logged on the user’s computer. (The latest version of Internet Explorer calls this InPrivate).

* To fight malware and phishing attempts, Chrome is constantly downloading lists of harmful sites.

Well, all in all this looks like an interesting project but how much of the speed, stability and user interface promises will be fulfilled – remains to be seen.
