15 Percent of US Teens Engage in 'Sexting


An estimated 15 percent of American teenagers have received nude or sexually suggestive photographs on their cell phones, according to a study Wednesday by the Pew Internet and American Life Project. The study about the tech-fueled trend called "sexting" said that boys are as likely as girls to send "sexts," while teens who pay for their own cell phone bills are more likely to text salacious shots.

The study of 800 teens found that just 4 percent of 12- to 17-year-olds admitting to sexting photos or videos of themselves. About 8 percent of 17-year-olds sent sexts and 30 percent received them, the report found.

Teenage sexting usually is done as part of a relationship or would-be relationship between teens, the Pew focus groups found. However, those messages are often forwarded to people outside the relationship, especially after a breakup.

"It doesn't take that many people creating these images for a lot of people to see them," said Amanda Lenhart, a senior research specialist at the Pew project and author of the report.

But researchers said the study still indicates sexting, which could lead to other problems such as cyber bullying, has become part of the fabric of modern teenage life. About 75 percent of US teenagers have cell phones and 66 percent of them send text messages, Pew said.

"Kids have experience with it," said Lenhart. "It's something they have to deal with and talk about in their lives." Originally posted on this page.

Ants Inspire: A New Computer Antivirus Software


Scientists have studied the behaviour of ants to develop a new generation of antivirus software for computers.
Watching how they reacted when a colony was under threat, gave programmers inspiration for a new weapon against infections known as worms and viruses. Ants use "swarming intelligence" to deter intruders. When one ant detects a threat, he is soon joined by many others to overwhelm their opponent.

Now the strategy is being incorporated into security software under test by a team at Wake Forest University, North Carolina, US.

The "digital ants" will wander through computer networks looking for invaders. When an ant detects one, it calls for an army of reinforcements to join the fight.

Researchers believe the new ant-based system will run faster than conventional security programs which have to be updated constantly to recognise new infections.

Professor of computer science Errin Fulp said: "In nature, we know that ants defend against threats very successfully.

"They can ramp up their defence rapidly, and then resume routine behaviour quickly after an intruder has been stopped. We were trying to achieve that same framework in a computer system."

The team believe that the new ant-based system will run faster than conventional security programs which have to be updated constantly to recognise new infections.

Researcher Glenn Fink added: "Our idea is to deploy 3,000 different types of digital ants, each looking for evidence of a threat.

"As they move about the network, they leave digital trails modelled after the scent trails ants in nature use to guide other ants.

"Each time a digital ant identifies some evidence, it is programmed to leave behind a stronger scent. Stronger scent trails attract more ants, producing the swarm that marks a potential computer infection."

Beware! Using Orkut Applications may Get Your Account Hacked!


Nope, this post title does not contain any typo. This is true that there are chances of loosing your account if you use different orkut applications without knowing much about them. Since Orkut allowed third parties to develop Orkut applications, many hackers joined this stream to fulfill their evil wishes. Although Orkut takes much time in checking each and every application manually before approving it, hackers add spywares to some iframes, used in the application. It’s pretty complicated to understand what’s going on in the background process for a normal user. Let me make it simple here so that you can protect your account from hackers.

Very recently one Orkut application developer was caught spreading spywares using his application. While opening his application on Google Chrome, browser stopped proceeding further after noticing the spyware threat. Have a look on this incident’s screenshot. (Screenshot clarity is very poor)

Hackers inject malicious iframes to their applications in any given time. They choose random time zones to release spywares. Although Orkut takes maximum security concerns and remove such applications from it’s directory immediately, those applications are having the ability to hijack hundreds of people’s accounts in a short span of time.

Here I would recommended you to use some powerful and strong antivirus systems on your system. You can also consider using Anti-Spywares to catch such spywares and remove them immediately from your system. If you want to know, how can they hack your account, read how hackers hack Orkut accounts.

Although there are a loads of safe and cool orkut applications, you should take the maximum care of your privacy and security. Use latest browsers (I recommended Firefox and Chrome) to get browser alerts on such suspicious attacks. If you have any such bitter experiences, don’t forget to share with us using the below comments section.

Google Earth Now Shows Real Time Rain and Snow


Now you can check out the weather in Google Earth. The latest version projects images of rain and snow over the areas with those weather patterns as it’s actually happening!! First enable the clouds layer, then zoom in to a particular location where it might be raining or snowing. Currently, precipitation data cover some areas in North America and Europe; you can see if it’s available in certain places by enabling the radar layer.
Google Earth is a great way to travel around the world from the comfort of your armchair and now it’s got a new feature that makes it even more immersive, real-time weather. If it’s raining or snowing in the location you’re currently visiting, the weather is depicted in Google Earth as well. It has some practicability, but there are probably better ways to get a weather report than to use Earth. None of them are as much fun though.

According to Quarup Barreirinhas, Software Engineer at Google, "This is a fun and useful tool for anyone planning to travel or who wants to check a specific area where a friend of relative might be visiting or living. For example, in preparation for my recent trip to the American southwest, I decided to check on the status of Hurricane Alex a few days in advance. Via Google Earth, I could see that the hurricane was entering Mexico and Texas. Zooming close to ground, I saw that the Texas coastline was getting a bit of rain".

Sign-in to Multiple Google Accounts at the Same Time

You may owned multiple Google accounts for various reasons but unfortunately you can't login on them at a same time coz Google or like practically any other website out there, doesn’t provide for this feature. Sometime it can be a headache to manage the different accounts. But now looks like that Google is working on a new feature which will enable users to be logged into several accounts at a time in the same browser.

As you know that Google account is most famous coz one of the best parts of having a Google account is that it works for all of the company’s products and can also be used to log into third-party sites in plenty of places. According the unofficial Google Operating System blog, Google is testing the functionality with a few users with the likely intent of releasing it for everyone in the future. For now, those can access it will be able to turn on the feature through their Google Accounts page.This feature will allow users to sign into different accounts in different tabs on same browser. For example, they can have two Gmail accounts opened concomitantly without one interfering with the other. The feature only works for a handful of Google sites for now, Calendar, Code, Docs, Gmail, Reader and Sites. There is a caveat for Gmail users, they won’t be able to use the offline feature if they enable multiple-account logins. Right now, you have to log out before logging in to a different account.

Google advices users that want to sign in with different accounts for the services that don’t support the feature yet to either log out of all their accounts and then login with the one they want or use a different browser. Of course, there is also the option of using the private browsing features in Chrome, Firefox and most other web browsers, as Google Operating System points out. I hope this feature will very helpful to users like me.

Nokia Unveils Bicycle-Powered Phone Charger

Now you can charge your phone just while you on track with your bicycle. Yes just for you the bicycle lover, Nokia unveiled on Thursday a bicycle-powered phone charger. The Nokia Bicycle Charger Kit, which can be attached to any bicycle, powers up from the pedaling motion of the bike's rider.. A dynamo--the electricity generator--is powered by the front bicycle wheel as a rider pedals and transfers electricity to a charger attached to the handlebar, which a phone plugs into. You can used this charger to power any Nokia phone with a 2mm power jack, according to Nokia. The Nokia bicycle charger comes with a dynamo that attaches to a bike's fork and generates electricity as a rider pedals. According to Nokia, "To begin charging, a cyclist needs to travel around six kilometers per hour (four miles per hour), and while charging times will vary depending on battery model, a 10-minute journey at 10 kilometers per hour (six miles per hour) produces around 28 minutes of talk time or 37 hours of standby time. The faster you ride, the more battery life you generate".

The kit comes with two small brackets, in addition to the charger and generator. One bracket attaches to the bicycle's handlebars to secure the charger and a cell phone holder. The other secures the small electric generator to the bike's fork.

Nokia is the world's largest maker of cell phones and very thinkfull towards green. Nokia said in a statement that its new product will provide "free and environmentally friendly electricity for mobile phones" and will likely be welcomed in areas of the world where bicycles are a transportation staple.

This kit priced you at about $18, the charging kit is set to be available from Nokia online and Nokia phone retailers by end of this year.

How to Speedup Slow Startup Times in Windows 7

Its an excellent article on speeding up boot-times in windows 7 by Sandro Villinger. Most of such articles do not go further than msconfig.exe, but this is not like that. Like this article talks about “MainPathBootTime” Smile. Windows 7 is a fast beast, especially when it comes to its startup process which was optimized dramatically compared to Windows Vista. No wonder, as Microsoft has a dedicated team focusing strictly on startup performance.

On a system with one- to two-year-old hardware, Windows 7 usually takes only 20 to 40 seconds to boot up. Even the performance-wise challenged netbooks rarely need more than a minute to be ready for work! Certainly, boot times vary significantly from one computer to another. This is nothing new. But if Windows 7 clients need way longer – and we’re talking way over one or two minutes – then you’re looking at a resource hog.

So what could be causing the problem?
* You just installed a new driver, which hasn’t been WHQL-certified and delays the boot up process. It could be a simple driver bug!
* You installed a piece of resource-intense software that initializes a process or a service during startup.
* You updated existing software or Windows 7 itself. Yes, it’s not unheard of that some updates cause a significant boot delay.

Or its may be a combination of all three causes. In any case, something is clearly taking up too much resources during startup time. To get to the bottom of the mystery, you need to follow a couple of step-by-step instructions to find and resolve the issue. Ready? Here’s how!

Find Out Exactly How Long Windows 7 Needs to Start Up:
Let’s start off by finding out the exact time the Windows 7 client needs to start up. And guess what, no stopwatch is required! Windows 7’s very own Event Viewer does the trick. In the following four steps you learn to measure both the raw boot time and the real life boot time (and what both mean).
