Energy and the Internet

HOME
There's been a lot of debate lately about the growing amount of energy needed to power the Internet, and we wanted to weigh in on the discussion. A few months ago, I first blogged about the about amount of energy used in one Google search. Our engineers crunched the numbers and found that an average query uses about 1 kJ of energy and emits about 0.2 grams of carbon dioxide. But those raw numbers don't really put the environmental impact of searching the Internet into perspective. To add some context, below is data about the C02 impact of some everyday activities and items compared to Google searching:
Activity
Google Searches
CO2 emissions of an average daily newspaper (PDF) (100% recycled paper)
850
A glass of orange juice
1,050
One load of dishes in an EnergyStar dishwasher (PDF)

5,100
A five mile trip in the average U.S. automobile
10,000
A cheeseburger
15,000
Electricity consumed by the average U.S. household in one month
3,100,000


We work hard to provide our users with the fastest products using the least amount of energy. We have a team of dedicated engineers focused on designing and building the most efficient data centers in the world. In fact, through efficiency innovations, we have managed to cut energy usage in our data centers by over 50 percent, so we're using less than half the energy to run our data centers as the industry average. This efficiency means that in the time it takes to do a Google search, your own personal computer will likely use more energy than we will use to answer your query. And the energy used by computers is growing; people are more plugged-in today than ever before in history. There are more than one billion PCs and laptops currently in use, and that number is expected to grow to four billion by 2020. 
We've got cell phones, PDAs, iPods, and GPS devices — not to mention the data centers that store all of our digital information "in the cloud." The electricity needed to run all of our computers, gadgets, and gizmos is growing and now accounts for half of all ICT emissions. (ICT stands for "information and communications technology.")
Although the amount of energy used to power ICT is growing, it's important to measure all of the ways information technology helps us save energy too. A study by The Climate Group, in fact, shows that ICT emissions pay for themselves (PDF) (and then some) by enabling significant reductions in emissions by other sectors of the economy. After all, it's much more efficient to move electrons than to move atoms. "Virtual" tools like email, video-conferencing, and search engines replace more carbon-intensive activities like snail mail, business travel, and driving.
We can still make progress at improving computing efficiency across the industry, however, and Google is committed to doing so. In 2007 we co-founded the Climate Savers Computing Initiative, a non-profit organization committed to reducing global CO2 emissions from the operation of computers by 54 million tons a year by 2010. Check out their website for more information on how you can reduce the environmental impact of your own computer use.




Global Melt Down

HOME
The inevitable has finally happened. The housing bubble in the US has burst. And the sub-prime crisis that resulted from the real estate bust in the US destroyed investor wealth worth trillions of dollars across the world.
The bust has claimed high profile investment banks like Bear Sterns (taken over by J P Morgan with dollops of help from the US Federal reserve, the US equivalent of Reserve Bank of India , Lehman Brothers (filed for bankruptcy on September 15 leading to the global turmoil since then) and, one of the most venerable insurers in the world, the American International Group (taken over by the US government for about $85 billion).
Today, the US government led by Treasury Secretary (US equivalent of India's finance minister) Henry Paulson (himself an ex-Goldman Sachs CEO, another investment bank facing the music) is planning to make provisions for an $800 bailout package that would buy all the bad loans and related products sold by US commercial and investment banks.
And since most of the US companies do business in India and with companies in India and the world over, the bailout will help restore the global confidence in financial systems like commercial and investment banks.
However, for the next two years the whole world, including India, is expected to reel under the effect of the current financial crisis considered as the worst since the Great Depression of 1929.
This is how it will affect us in India.
1. Slowdown in jobs
Companies like Lehman Brothers, Merrill Lynch, AIG and Morgan Stanley, to name a few, have their captive research units, brokerage arms, investment banking arms in India employing several hundred thousand people in what is popularly known as BPOs (Business Process Outsourcing) and KPOs (Knowledge Process Outsourcing). Lehman Brothers' Powai unit itself employed about 2,200 people most of whom will be rendered unemployed unless some other company buys out Lehman's India operations and keeps the wheels running.
2. Increase in loan rates
First it was the inflation rate that spoiled the party for Indian borrowers of home loans, personal loans and credit card purchases. Now taking a cue from the US banks -- which today are so wary that they are not even lending to each other for the fear that they may not get their money back -- Indian banks too have decided to thoroughly scrutinise the repayment capacity of Indian borrowers
As their cost of money goes up banks will pass on this increase to their customers, ie, borrowers like you and me, at a higher rate of interest. If banks feel that borrowers may not return their money they are going to price it higher to cover the risk of a few defaulting on their payments
3. Correction in real estate prices
There is some good news, though. If experts are to be believed real estate prices in Indian towns and cities are likely to come down by 10-15 per cent in the next few months.
The reason given is most US companies that had bought stakes in Indian real estate companies are facing a cash crunch. Others who had promised to invest in Indian real estate will not do so for the simple reason that the US is no more the place where you can get dollars easily and at a cheaper rate.
4. Increase in gold prices
Because of the financial problems in the US global investors are losing their faith in the supremacy of the US dollar as a store of value. As a result they are selling dollars to buy some other currency, say the euro or the Japanese yen.
Whenever such an event happens investors flock to that ultimate store of value called gold or the noble metal. As the festival season starts with Navratri in India more and more people will demand gold thereby increasing its price further.
5. More inflation
Increase in oil prices -- it jumped a whopping $30 a barrel in intra-day trade today before settling at $108-109 to a barrel -- and weakening of the Indian rupee against the dollar will act as a double whammy for Indians.
Crude prices have a multiplier effect. As most goods transported in India use some or the other form of energy it increases the cost of transportation and hence an increase in the price of vegetables, pulses etc.
6. Speed breaker ahead
Future Group Chairman Kishore Biyani had, way back in 2007, said that 2009 will be a crucial year for the world economy as a whole and particularly India. How very prophetic his words sound today.
With the US economy firmly in the grip of a slowdown owing to the housing price collapse and the subsequent sub-prime drama, this slowdown is fast snowballing across global boundaries and more so India as we depend a lot on the US for the money they bring in.
7. Rollercoaster ride
Be prepared to ride the ups and downs of the global financial markets as India is no more an isolated island. India is likely to follow whatever happens in the US, European or Asian stock markets.
A case in point is how the Sensex closely traced the ups and downs of the Dow Jones and Nasdaq in the previous week.
The same is true of the prices of oil, gold, aluminium, copper steel and any other commodity. Gone are the days when markets defied Newton and gravity. Nobody can expect the markets to move only in one direction.
If you are a trader in such a market, then not even God can save you.



Swine Flu- Symptoms & Preventions






Swine flu in India is spreading like wildfire, taking the toll to 14. Officials say there are currently more than 800 cases of the H1N1 flu strain in India. Governments from all around the world are finding ways to combat this deadly disease. So what can you do to protect yourself? Stay calm and practice these 10 effective prevention tips.
1. Wash your hands frequently
Use the antibacterial soaps to cleanse your hands. Wash them often, at least 15 seconds and rinse with running water.
2. Get enough sleep
Try to get 8 hours of good sleep every night to keep your immune system in top flu-fighting shape.
3. Keep hydrated
Drink 8 to10 glasses of water each day to flush toxins from your system and maintain good moisture and mucous production in your sinuses.

4. Boost your immune system
Keeping your body strong, nourished, and ready to fight infection is important in flu prevention. So stick with whole grains, colorful vegetables, and vitamin-rich fruits.
5. Keep informed
The government is taking necessary steps to prevent the pandemic and periodically release guidelines to keep the pandemic away. Please make sure to keep up to date on the information and act in a calm manner.
6. Avoid alcohol
Apart from being a mood depressant, alcohol is an immune suppressant that can actually decrease your resistance to viral infections like swine flu. So stay away from alcoholic drinks so that your immune system may be strong.
7. Be physically active
Moderate exercise can support the immune system by increasing circulation and oxygenating the body. For example brisk walking for 30-40 minutes 3-4 times a week will significantly perk up your immunity.
8. Keep away from sick people
Flu virus spreads when particles dispersed into the air through a cough or sneeze reach someone else’s nose. So if you have to be around someone who is sick, try to stay a few feet away from them and especially, avoid physical contact.
9. Know when to get help
Consult your doctor if you have a cough and fever and follow their instructions, including taking medicine as prescribed.
10. Avoid crowded areas
Try to avoid unnecessary trips outside. Moreover, avoid touching your eyes, nose or mouth. Germs spread this way.


BHUVAN- An alternative of Google Earth

HOME
ISRO launched the beta version of its web-based 3-D satellite imagery tool, Bhuvan, on August 12, 2009. Bhuvan will offer superior imagery of Indian locations compared to other Virtual Globe software with spatial resolutions ranging from 10 m to 100 m. Locations can be viewed from different perspectives and will allow for the measurement of distances. The Bhuvan portal is designed to run on slow Internet connections. The imagery would steer clear of all sensitive military installations in India for security concerns.
Bhuvan images of India along with a number of other interesting features which include weather information and even administrative boundaries of all states and districts, relevant only to the country. Bhuvan is equally capable of offering images of the globe, but the best resolution area includes India at the moment. In the Indian subcontinent, Bhuvan will be able to display a picture from ten meters away that is; a commuter moving on the road can be easily spotted.
National Remote Sensing Agency played an important role in the creation of this product. ISRO has used data provided by satellites including Resourcesat-1, Cartosat-1 and Cartosat-2 to get the best possible imagery for India. ISRO claims that the application can provide imagery of up to 10 metres for major Indian cities compared to 200 meters provided by Google Earth.

CHANDRAYAAN- a Journey to Moon

HOME
Chandrayaan-1

Chandrayaan-1 was India's first unmanned lunar probe. It was launched by the Indian Space Research Organisation in October 2008, and operated until August 2009. The mission included a lunar orbiter and an impactor. India launched the spacecraft by a modified version of the PSLV, PSLV C11 on 22 October 2008 from Satish Dhawan Space Centre, Sriharikota, Nellore District, Andhra Pradesh, about 80 km north of Chennai, at 06:22 IST (00:52 UTC). The mission was a major boost to India's space program, as India researched and developed its own technology in order to explore the Moon. The vehicle was successfully inserted into lunar orbit on 8 November 2008.
On 14 November 2008, the Moon Impact Probe separated from the Chandrayaan orbiter at 20:06 and struck the south pole in a controlled manner, making India the fourth country to place its flag on the Moon. The probe impacted near Shackleton Crater at 20:31 ejecting underground soil that could be analysed for the presence of water ice.
The estimated cost for the project was Rs. 386 crore (US$ 80 million).The remote sensing lunar satellite had a mass of 1,380 kilograms (3,042 lb) at launch and 675 kilograms (1,488 lb) in lunar orbit. It carried high resolution remote sensing equipment for visible, near infrared, and soft and hard X-ray frequencies.
Over a two-year period, it was intended to survey the lunar surface to produce a complete map of its chemical characteristics and three-dimensional topography. The polar regions are of special interest as they might contain ice. The lunar mission carries five ISRO payloads and six payloads from other space agencies including NASA, ESA, and the Bulgarian Aerospace Agency, which were carried free of cost.
                   After suffering from a bout of minor failures, which included failure of the star sensors, Chandrayaan stopped sending radio signals at 20:00 UTC on 28 August 2009 (29 August 2009, 1:30 AM IST). The ground control had lost contact with the spacecraft and the mission was declared to be terminated. Chandrayaan operated for 312 days in lunar orbit.

Chandrayaan-2

Chandrayaan-2  is the second unmanned lunar exploration mission proposed by the Indian Space Research Organisation (ISRO) at a projected cost of Rs. 425 crore (US$ 90 million). The mission includes a lunar orbiter as well as a Lander/Rover.
ISRO plans to land a motorized rover on the Moon likely in 2012, as a part of its second Chandrayaan mission. The wheeled rover will move on the lunar surface, to pick up soil or rock samples for on site chemical analysis. The data will be sent to Earth through Chandrayaan II, which will be in lunar orbit.
On 22 October 2008, after the launch of Chandrayaan-1 it was announced that the probable launch of Chandrayaan II would be the end of 2009 or early 2010. The launch vehicle would be the GSLV. The team headed by Mylswamy Annadurai that was behind the success of the first mission would work on Chandrayaan-2.
ISRO announced that Chandrayaan-2 was delayed once again to at least 2013.


Web addresses exceed world's population

HOME
Internet 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 per cent of their population)
* 2 - US (227,190,989, or 74.7 per cent)
* 3 - Japan (94,000,000, or 73.8 per cent)
* 4 - India (81,000,000, or 7.1 per cent)
* 5 - Brazil (67,510,400, or 34.4% per cent)

G-mail in Hindi

HOME
Marking the online e-mail service’s fifth birthday, Google announced it is going global with its Gmail Labs box of quirky functions it launched last year in English. Google originally announced the service on 1 April 2004, and some in the industry thought that the whole thing was an April Fool’s Day hoax. Since then it has grown to become one of the most popular webmail services around.
Gmail Labs will now be available internationally in 49 languages. Currently Google is supporting five Indian languages – Hindi, Tamil, Telugu, Kannada, and Malayalam, and businesses and schools using Google Apps should see this in the coming weeks. 
“Until now, there hasn’t been a good way to send email to friends and family in Hindi, my native language and their language of choice,” writes Anuj Sharma, Software Engineer at Google. 
If you’re in India, this feature is enabled by default. If not, you’ll need to turn it on in the “Language” section under Settings. Once enabled, just click the Indian languages icon and type words in the way they sound in English — Gmail will automatically convert them to their Indian language equivalent.
New features include undo send, a way of retracting an e-mail up to five seconds after you hit the send button; mail goggles, which makes you solve some math questions before sending a message, to make it harder to send messages while inebriated; and a forgotten attachment reminder, which reminds you to attach a file if you mention one in your message.

ØPankaj Advani created history by becoming the second Indian, after Geet Sethi, to win the World Professional Billiards Championship at the Northern Snooker Centre here. The 24-year-old Indian pulled off a huge surprise by defeating nine-time winner Mike Russell of Qatar 2030-1253 after having a 800-plus lead at the break. Advani made a break of 226 and six more centuries on his way to lift his first Professional billiards world title. He has already won the amateurs world billiards and snooker Championships. Geet Sethi was the last Indian to win in 2006, his first being in 1992. Russell had defeated Indian Rupesh Shah in the semifinal 1366-880, while Advani beat compatriot Dhruv Sitwala 1037-972.




ØIndian boxing's jinx-breaker Vijender Singh achieved yet another historic feat as he ensured the country's first medal in the World Championships by advancing to the middle-weight semi-finals in Milan, Italy. The world number two and top seed Vijender out-punched Ukrainian Sergiy Derevyanchenko 12-4 to become the first Indian to make the last-four stage of the prestigious event.

Microsoft bets on making "dumb" phones smarter

HOME
Microsoft today announced a new phone app service—not for smartphones, but instead for the world’s cheapest and low-tech handsets. Called OneApp, the software was developed by Microsoft’s Unlimited Potential Group, which researches technology that can be used by poor people living in emerging-market nations. OneApp allows consumers with existing, non-smartphone devices to access Web sites such as Twitter, Facebook, in an efficient way.
OneApp’s been engineered to not require much in terms of data usage and memory; it runs only one individual application at a time. The graphics are lower resolution than those in iPhone apps. The phones running OneApp don’t need to eat up as much energy running the mini-software programs, either, according to Amit Mital, who heads the Unlimited Potential Group at Microsoft.
Why is Microsoft investing in making “dumb” phones smarter?
For one, the market for these phones is huge. Think about India alone: according to market researcher Gartner, mobile-phone market penetration in India is predicted to jump from 38.7% in 2009 to 63.5% by 2013. Gartner analysts say that this is mainly due to a focus on the rural market, more local Indian companies entering the sector, and the increased availability of cheaper phones. “The basic, or ‘feature’ [mobile] phone market as it’s known, is one with billions of customers,” says Mital. “Today, 'feature phones' are more common than smartphones. But there is a demand for apps, which are hard to find for these 'feature phones.'”Two, Microsoft wants to introduce users of relatively low-tech mobile phones to Micrsoft’s “cloud” computing services via their handsets, which in essence the OneApp program does. This would increase its market share in this area.
Three, much of Unlimited Potential’s developing-world research eventually “trickles up” to mainstream products for the developed world. Consider the launch earlier this year of a simpler version of Windows, based on Microsoft’s Starter Edition for Windows, once available only in emerging markets, but now available worldwide on netbooks. Mital can't talk about how OneApp might affect Windows Mobile software in the developed world. But imagine how some design and engineering elements, such as sleeker, simpler on-screen graphics or the ability to deliver apps without eating up data usage, could come in handy when designing software for developed-world audiences, too.
Four, Microsoft also wants to be influential in the promotion and use of so-called “mobile wallets,” or turning the phone into a purchasing or banking tool.
Finally, Microsoft will open up the software developer’s kit for OneApp, making it possible for anyone in the world to create apps for these basic phones. The launch of OneApp will feature about a dozen free apps, but soon programmers and entreprenurs in both emerging and mature markets can potentially find new revenue streams if they charge for their apps.
Sure, smartphones like the iPhone and the BlackBerry might be the fastest-growing segment in the mobile-phone space—up 27% worldwide from last year, according to Gartner. But for those who can’t afford smartphones, and for those who are enterprising enough to capitalize on a surprising new market, yesterday’s “dumb” phones might just look like a clever new way to ride the app wave.
