From the Desk of “Head of Department”

HOME
Heartiest congratulations to Association of Computer Technocrats (ACT) of Dept. of Computer Technology for making such a beautiful, content-rich E-magazine 'Imagin@CT'. The Magazine Committee deserves the credit for it. The department has planned to come up with one such E-magazine every coming semester besides one Souvenir. I am proud to announce that it has taken up the initiative to start up the Student Chapter of Computer Society of India (CSI) at our college. The department is already successfully running Oracle Workforce Development Programme, OWDP of Oracle University, USA. I am also proud of those students who are Rankers at the recently concluded University Examinations.

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 elseĆ¢€™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.
