Smoker IQ vs Non-Smoker IQ

We have heard that smoking is injurious to health and smokers are very prone to diseases, but new study states that cigarette smokers also have lower IQs than non-smokers.

According to a study of over 20,000 Israeli military recruits, it is found that young men who smoked a pack of cigarettes a day or more had IQ scores 7.5 points lower than non-smokers. “Adolescents with poorer IQ scores might be targeted for programmes designed to prevent smoking,” said Dr Mark Weiser and colleagues from Sheba Medical Center in Tel Hashomer, who did the study. The researchers looked at 2,0211 men who were 18-year-old and recruited into the Israeli military. The group did not include anyone who was having major mental health
problems.

According to the study, the average IQ for non-smokers was about 101, while it was 94 for men who had started smoking before entering the military. The IQ steadily dropped as the number of cigarettes smoked increased, from 98 for people who smoked one to five cigarettes daily to 90 for those who smoked more than a pack a day. IQ scores from 84 to 116 are considered as the average intelligence.

IPCC’s Himalayan glacier controversy – Meaning

The media has been buzzing about the IPCC’s Himalayan glacier controversy.

The international climate panel headed by Dr. Rajendra Pachauri won the Nobel Peace Prize in 2007 for a ground-breaking report on climate change. Several small errors have now surfaced in the 3,000-page report.

If you’re wondering what the news reports mean for climate change, here are some answers. Please spread the word to your family, friends, and co-workers.

1. Do the U.N. climate panel’s errors mean there is no threat from climate change?

No, the dire threat from climate change is not in question. The panel’s errors were only related to the intensity of climate change. There are in fact only two real mistakes that have been found so far and neither point to any change in the basic premise of human induced climate change. [1]

For over two decades, scientists have consistently found that climate change is happening, and it’s caused by human activity. [2]

2. Why is there so much furore about these errors?

Over the past 20 years, the U.N. climate panel has been attacked again and again by the fossil fuel industry and by politicians who are determined to discredit climate change science and continue on an unsustainable development pathway which would ensure dire consequences for this earth. [3]

3. Are the Himalayan glaciers melting or not?

In 2007, the U.N. climate panel reported that Himalayan glaciers might vanish by 2035. The specific year turned out to be based on a flawed study, and the panel has corrected the error. [4]

The Himalayan glaciers are retreating, but the exact rate of retreat is still uncertain. India’s Environment Minister Jairam Ramesh was one of the first to argue that the 2035 forecast was “not based on an iota of scientific evidence,” but he confirms the Himalayan glaciers “are indeed receding and the rate is cause for great concern.” [5]

4. Who will be impacted by climate change?

Everyone. Lesser developed countries and small island states will be hit hardest and fastest. [6]

But rich nations are not immune to the violent weather, drought, disease, famine, mass migrations, and wars that will be caused if we don’t stop climate change. [7]

5. What is Greenpeace’s call on climate change?

The science is clear. Climate change is real, is happening now and is caused by people. The solution is clean energy, smart use of our power and forest protection.

If enough of us take action, we can stop climate change. Sign up to help by clicking here:

India 3rd Largest Economy by 2012

It seems that global slowdown made a shift in global economic power. Global consultancy firm PricewaterhouseCoopers believes that India has potential to become the world’s third largest economy by purchasing power parity, overtaking Japan in 2012.

If this happens, it would be almost 20 years ahead of Goldman Sachs’ projection of 2032 in its BRIC (Brazil, Russia, India, China) report. The PwC report stated that even Indian economy is expected to grow faster that China after 2020. China was projected to become the world’s largest economy by 2041, now looks set to achieve the distinction sometime around 2020.

John Hawksworth, PwC Head of Macroeconomics said, “While the exact date is open to doubt, it seems highly likely that, by 2030, China will clearly be the largest economy in the world on PPP.”

According to a PwC report, the top 10 economies by 2030 will be China, the U.S, India, Japan, Brazil, Russia, Germany, Mexico, France and Britain. According to report, China is likely to be some way ahead of the U.S. by 2030. It is also predicted that China’s share in global GDP will be 19 percent by 2030, while the proportion for the U.S. and EU will be 16 percent and 15 percent, respectively.

Chinese used ‘flaws’ in Microsoft explorer to hack Google

The Chinese managed to hack Google accounts of human activists and many businesses thanks to flaws in Microsoft’s Internet Explorer (IE) browser, according to reports Friday.

Google has threatened to close its operations and offices in China after hacking and “phishing” attempts to break into gmail accounts of US, China and Europe based Chinese human rights activists.

The company, which agreed to censor of Google.cn at its launch in 2006, has also said it is “no longer willing to continue censoring our results on Google.cn.”

Reports Friday quoted security researcher McAfee Inc. as saying that Chinese cyber attacks on Google accounts were engineered by using an unknown flaw in Microsoft’s Internet Explorer browser.

According to McAfee, ‘phishers’ fooled users into clicking on a link to a website. This website then secretly downloaded malicious software onto their computers. The spyware allowed the hackers to take remote control of the computers.

Microsoft has already admitted in its blog that IE browser might be used by hackers to remotely spy on infected computers. It is likely to unveil a software update for the browser.

“We need to take all cyber attacks, not just this one, seriously,” Microsoft Chief Executive Steve Ballmer told CNBC.

“We have a whole team of people that responds in very real time to any report that it may have something to do with our software, which we don’t know yet,” he said.

Google has said that “these accounts have not been accessed through any security breach at Google, but most likely via phishing scams or malware placed on the users’ computers.”

It says it will soon hold discussions the Chinese soon whether it can operate an unfiltered search engine. “We recognize that this may well mean having to shut down Google.cn, and potentially our offices in China,” Google warned in a blog Tuesday.

Dell displays Android powered slate PC

In a move to explore another type of device designed for computing on the go, Dell displayed a small slate computer that could hit the market this year. Dell’s slate has a 5-inch screen and runs on Google’s Android mobile operating system.

The company did not to provide other details of the gadget, or say definitively if it could be available in the market, reports Reuters. The slate and tablet PCs are very popular at the Consumer Electronics Show in Las Vegas this week, ahead of a highly anticipated device from Apple that is widely expected to be unveiled later this month.

Microsoft Chief Executive Steve Ballmer displayed a Hewlett-Packard’s slate that was considerably larger than Dell’s, which looked like a large smartphone. Michael Tatelman, Dell’s vice president of consumer sales and marketing, said the company is testing a number of different screen sizes as it pushes further into the mobile market. The company recently released its first smartphone, the Mini 3, which is on sale in China and Brazil, and will be available in the U.S. on AT&T’s network.

Simple Phone Still Leads In The sale Market

The craze for the smartphones may be on all time high, but majority of the phones used around the world are still normal cheaper phones. According to data from the Nielsen Company, roughly 82 percent of cellphones in use are limited-function phones, the kind that typically sell for less than $50 or are given away with a two-year service contract.

These simple phones, also called as feature phones are improving in quality and standard. “Feature phones are migrating away from the tiny screens that characterized their dominance in the era of the Motorola Razr,” said Ross Rubin, an industry analyst with the NPD Group, a market research company. “They have more sophisticated operating systems, touch screens and bigger screens.”

Sleek offerings from Samsung, LG and Motorola have attracted the attention of entrepreneurs and software companies hoping to market functions similar to those found on the iPhone. One phone, the LG Vu, for example, has a three-inch touch screen with “haptic feedback” so the user feels a response when tapping on the screen, a 2-megapixel camera and up to four gigabytes of external memory – enough to fit hundreds of additional applications.

Another, the Motorola Clutch, has a Web browser, support for GPS functions and is Bluetooth enabled. These phones typically come loaded with a simple suite of applications selected by the carrier, like puzzle games, a mobile e-mail application, a navigation application and an instant-messaging client. “These companies are trying to raise the bar from the lowest common denominator,” Rubin said.

One may think that majority of the developers are now focused on making applications for the app store of Nokia, Apple and others. But this fact may not be entirely tru considering the reach of smart phones as opposed to feature phones. So many companies have continued to make applications for feature phones. One such company, GetJar, offers about 60,000 applications for nearly 2,000 different mobile phones, including the Motorola Rokr. Feature phone users can find YouTube, Tetris, the restaurant locator Urbanspoon and a range of expense-tracking and calorie-counting apps. But just because consumers have simple cellphones doesn’t mean they don’t want Facebook, Wikipedia or a popular instant-messaging application like Nimbuzz on their phones, says Ilja Laurs, Chief Executive of GetJar, which is based in San Mateo, California, and Lithuania. “Everyone wants apps, but not everyone can afford an iPhone,” Laurs said. At the end of December 2009, the company said nearly 55 million applications were being downloaded each month, an increase of 260 percent from the period a year earlier. “We’re on track to hit a billion total downloads in about two months,” Laurs said.

“For every top 100 apps you hear about, there are literally tens of thousands of additional apps that never make it to any top lists because of the noisy environment of an app store,” he said. These niche applications, he said, have the potential for success on a site like GetJar, which caters to a broad set of phone users outside the iPhone or Android-powered system. About a third of GetJar’s traffic comes from smartphones, the company said, and the rest is from feature phones.

A Thousand in Maharashtra Say No To Coal

Alibaug Taluka, India – Close to a thousand villagers stood for hours in the formation of a life-size human windmill near Khidki village in Alibag, in what could well be the largest protest for renewable energy in India to date.

They were demanding that the Maharashtra Government drop plans to build 10,000MW coal-fired thermal power plants in the region and explore renewable energy instead. The villagers said they were committed to fight the acquisition of their fertile land for coal-based power plants.

“We believe that the energy planned from these coal plants is dirty. It can come instead from clean alternatives like wind and solar energy, and by using energy more efficiently. We will not give up our land and our future to these mega power plants that will pollute our air, land, and water. We will not allow them to ruin our children’s future by adding to the problem of climate change,” said Dr Vishnu P. Mhatre of the Naugaon Sangharsh Samiti, one of the organisations fighting for clean energy here.

The community is opposing plans to set up thermal power plants over 8,500 acres of fertile land. The companies involved are the Tata Power Company Limited (1,200MW) and the Maharashtra Energy Generation Limited, a Reliance subsidiary, (4,000MW) at Shahpur in Alibag. The Patni group (500MW) and the Ispat group (2,000MW) want to set up their plants in the adjacent Medekhad Khadi.

For more than four years, the villagers have been resisting attempts by the government and the companies to acquire their land. “We do not oppose production of energy. But, we strongly demand that the Government of India change its energy pathway and move towards decentralised renewable energy, which will be used locally for agro-based industries and domestic needs,” said Satish Londhe, a resident of Alibag and state coordinator of the Shramik Mukti Dal.

To prove their solution-oriented approach, the citizens later joined in setting up a wind station. Admiral Ramdas, a Magsaysay awardee and a resident of Alibag, inaugurated the “Citizens’ Wind Monitoring Station” where the residents would record the area’s wind potential through an anemometer. This would show that the region has huge potential for wind energy, and challenge the government’s inaction in investing in alternate energies.

“Policymakers in the central and state governments need to explore the possibility of renewable resources like the wind, the sun, and other agents before rushing to coal for energy. In the current environment of global concern over climate change, we must also look critically at the operational efficiency of our power plants and increase energy efficiency in all sectors. This will ensure a dramatic reduction in our energy demand,” Ramdas asserted.

Maitree Dasgupta, Climate Campaigner with Greenpeace India, said: “This protest is a sign of popular opposition fomenting against coal in India, which will only grow. This not a fight against growth or development. It is just the opposite. It is a fight for building energy infrastructure for the future instead of relying on dinosaur technologies. India can get 35% of its power from renewable energy by 2030. We have the ability and technical capacity; we only need the political will.”

Greenpeace India is demanding that Prime Minister Manmohan Singh put in place a National Renewable Energy Bill no later than 2010, which would enable a shift towards a more sustainable energy pathway. This implies that the draft bill be made public this year for debate before placing it for parliamentary approval. It would also provide a framework for the Solar Mission and show that India is serious about the mission. More than 50,000 Indians have already signed Greenpeace India petitions demanding a response on this from Manmohan Singh.

Microsoft’s .net vs Sun’s Java

With the markets soaring towards recovery, IT companies have started hiring again. A quick survey of the recruiting trends has revealed that amidst the hiring spree Java programmers are gaining the edge over .Net professionals. Though, this trend has been present in the market for quite some time, the cost-cutting factor has led companies to prefer Java programmers more. “Java is more in demand because it is open source, which is comparatively cheaper than using .Net, so companies have started adopting Java,” says Anuj Agrawal, Director of Zyoin.

The flexibility that Java brings through its open source framework, has made it more popular. .NET in its complete form can only be installed on computers running a Microsoft Windows operating system, whereas Java can be installed on computers running any operating systems such as Linux, Solaris, Mac OS or Windows.

Rishi Das, Co-founder and CEO of CareerNet Consulting feels that the increase in the number of online startups is also fueling the demand for Java programmers. “Java is in demand because there are more companies developing user interface and web applications for their clients. The rise in popularity of software as a service (SAAS) model is also giving the edge to the Java professionals,” he says. Das also adds that only major players like Dell, Sapient, Citrix and MindTree are hiring .Net professionals because they have been using the Microsoft platform for a long time now.

Though, the trend shows that Java programmers are gaining over their .Net counterparts, there are some who feel that there are verticals where .Net has its own advantage. “Though there is an equal demand for both Java and .Net programmers, our clients in verticals like BFSI and telecom still prefer .Net,” says Namitha Vyas, Team Integrator at an IT recruitment firm.
