Pakistan's liberal voice is going to be diminish, which is a dangerous precedent. The way in which killer of Punjab province governor was welcomed with so much rose explain how ultra conservative muslim is going influence a major portion of public thought. Recently after US issued a bounty on Hafiz Saeed when 'anti america' emotion with nationalist mood is at it's peak level simply fuel spread of 'mullah ' thought (orthodox & anti america anti india) on internet via social networking site. Therefore Zardari govt's little effort to check it is a good step.

Scientists Question Safety of New Airport Scanners 357

An anonymous reader sends this quote from a story at NPR about the accelerated deployment of new scanning machines at airports: "Fifty-two of these state-of-the-art machines are already scanning passengers at 23 US airports. By the end of 2011, there will be 1,000 machines and two out of every three passengers will be asked to step into one of the new machines for a six-second head-to-toe scan before boarding. About half of these machines will be so-called X-ray back-scatter scanners. They use low-energy X-rays to peer beneath passengers' clothing. That has some scientists worried. ... The San Francisco group thinks both the machine's manufacturer, Rapiscan, and government officials have miscalculated the dose that the X-ray scanners deliver to the skin — where nearly all the radiation is concentrated. The stated dose — about .02 microsieverts, a medical unit of radiation — is averaged over the whole body, members of the UCSF group said in interviews. But they maintain that if the dose is calculated as what gets deposited in the skin, the number would be higher, though how much higher is unclear."

19th-Century Photographer Captured 5,000 Snowflakes 80

tcd004 writes "Wilson Bentley began photographing snowflakes in 1885, and managed to immortalize more than 5,000 crystals before his death in 1931. Now his images are widely recognized and highly sought after. At the age of 19, 'Snowflake' Bentley jury-rigged a microscope to a bulky bellows camera and took the first-ever photograph of a snowflake. Photography then, particularly microphotography, was much closer to science than art. In a 1910 article published in the journal Technical World, he wrote, 'Here is a gem bestrewn realm of nature possessing the charm of mystery, of the unknown, sure richly to reward the investigator." The video embedded at the link above touches on another long-forgotten piece of history: a sketch of the photographers who captured arial views of assemblages of tens of thousands of soldiers returning from WW-I, carefully choreographed and arranged to form a Liberty Bell, a Stature of Liberty, a US flag... as forgotten as the origin of the WW-I term razzle-dazzle.

+ - Meaning of Friendship

Submitted by

whatanews4u writes "I can only imagine the angst that Jessica Vascellero at the Wall Street Journal inserted into countless minds this evening with her article about the difficulties people are having defining what is and isn't a "friend" for online social networking purposes.

Most Americans who aren't teenagers or a little older are just getting used to the idea of social networks in general. But the complicated and evolving rules about what constitutes friendship online is adding even more stress.

One young woman had to face someone she defriended on Facebook in a chance encounter on an elevator, and re-added the person to rid herself of the guilt. A middle aged jeweler frets over the implied meaning a competitor unfriending him. Meanwhile, the web-savvy David Dalka, saying he doesn't need to know "you've changed to a new brand of peanut butter," has unceremoniously dropped people from his friend list at LinkedIn.

So What Is An Online Friend, Anyway?

The social networks themselves, and those of us who spend a lot of time there, are still trying to work out the details on what it means to be a friend with someone online. With friendship comes benefits — you get a stream of information about the person, but it also has costs (you have to wade through a stream of information about the person, and they get access to your intimate details).

Facebook in particular has struggled with this. For a time they really just wanted users to be online friends with people they already know in the offline world. That messaging has subtly changed more recently, though, to a less rigorous position.

It's clear that the more friends you have on any given service, the more noise you have to wade through to find the golden signal. In the real world when you don't want to be friends with someone, you just find ways not to spend time with them. But online, you click that friend button because it seems so easy, and it's considered insulting if you don't. And then you pay.

Social networks are taking two approaches to dealing with this. MySpace and Facebook (and those like them) have added different buckets to throw friends into. You can share more or less information with different groups of friends. So if you aren't really friends with someone but don't want to insult their friend request, you can throw them into the unwashed masses bucket (or whatever you want to call it).

The other approach is the one taken by sites like Twitter and Friendfeed. Anyone can follow anyone and watch what they're up to, but you are under no pressure to reciprocate. The problem with this approach is that there is still a lot of social pressure to follow people back. I suggested a "fake follow" back in August so that you can just pretend to follow those people. Friendfeed now has a feature which allows just that.

But bucketing friends just seems like a bolted on way to fix the problem. And managing the changing relationships you have with of hundreds or thousands of people across multiple sites is a real time sink. In the future, the services should be able to do a much better job of just figuring out, through your gestures, who you are really close to and who you aren't. It may also define a relationship with someone I don't know at all based on whether or not we have friends in common. So even if there is no interaction at all, Facebook and MySpace (or whoever) can theoretically have an idea of how much personal information to share between us.

Ultimately, though, our culture is adapting just as quickly as the networks are. Facebook's Mark Zuckerberg has said users are becoming more and more comfortable sharing online. Sometimes (ok, often) Facebook is pushing the envelope when it comes to deciding on my behalf what is shareable and what isn't. They're placing aggressive bets on where this is all evolving. And sometimes they lose the bets (but not always).

But where they are correct is that there is no bright line of right and wrong when it comes to defining online friendship. The algorithms and the humans will meet somewhere in the middle."

All the evidence concerning the universe has not yet been collected, so there's still hope.
