Use of Internet affecting memory

Researchers have found that the widespread use of search engines and online databases is affecting the way people remember information. To know whether people were more likely to remember information that could be easily retrieved from a computer, Betsy Sparrow, an assistant professor of psychology at Columbia and her collaborators, Daniel M. Wegner of Harvard and Jenny Liu of the University of Wisconsin, Madison, staged different memory experiments, reports the New York Times.


In one experiment where participants typed 40 bits of trivia, the team found that the subjects were significantly more likely to remember information if they thought they would not be able to find it later.

“Participants did not make the effort to remember when they thought they could later look up the trivia statement they had read,” wrote the authors.

A second experiment was aimed at determining whether computer accessibility affects precisely what we remember.

“If asked the question whether there are any countries with only one colour in their flag, for example,” the researchers wrote, “do we think about flags — or immediately think to go online to find out?”

In this case, participants were asked to remember both the trivia statement itself and which of five computer folders it was saved in. The researchers were surprised to find that people seemed better able to recall the folder.

“That kind of blew my mind,” Dr. Sparrow said.

The experiment explores an aspect of what is known as transactive memory — the notion that we rely on our family, friends and co-workers as well as reference material to store information for us.

The Internet’s effects on memory are still largely unexplored, Dr. Sparrow said, adding that her experiments had led her to conclude that the Internet has become our primary external storage system.

“Human memory,” she said, “is adapting to new communications technology.”

Doctors save baby by 'freezing' in a fridge

Newly born baby didn't breathe for 17 minutes.
A baby who didn't breathe for 17 minutes was saved after being put in a 'fridge' for three days, reported The Daily Mail.




When she was born, Sophie Fleet swallowed fluids which caused a blockage in her airways and starved her brain of oxygen.

Doctors treated her using medically-induced hypothermia, lowering her body temperature from the normal 37°C to 33.5°C for three days by putting Sophie into a special 'fridge' suit pumped with water to keep her body cool, reported The Daily Mail.

This reduced pressure on Sophie's brain, thereby preventing further brain damage. She could go home with her parents nine days later, and only sustained mild brain damage.

Sophie's parents know that the outcome could have been much worse – their daughter could have suffered either severe or brain damage – without the hypothermia, reported The Daily Mail.

Is it Facebook or spambook?

Clicking on chat messages containing unknown links may make you vulnerable to hackers, lead to data theft

'Facebook'ing nowadays is becoming more and more unsafe, with users being bombarded with spam messages containing malicious links. Police and cyber experts have warned netizens about this new 'phishing' method, and appealed to them to refrain from clicking on suspicious links.  This new spam is activated through the usual Facebook chats, often without the sender even coming to know about it.

Beware: The new spam is activated through facebook chats

How it works
When you are online on FB chat, suddenly a chat window opens from an online friend. This chat window does not contain the usual 'Hi' or other greeting from your friend; rather, it contains a link. While the user is under the impression that this link is sent by his friend, it is actually spam. The link, when clicked on, spreads viruses.  Not only that, the sender is also unaware of any links sent through his chat account. This is a chain spam message. If you click on it, it also gets forwarded to the other friends on your list.

Gaurav Patil, working with a reputed software company says, "I was absolutely unaware that it was spam. I was under the impression that my friends were sending useless links. Till date, I've never bothered clicking on them. I tried asking a friend, who then told me that it happens through some application. That's all I know."
Sneha Sringare, a MA student of Fergusson College said, "I have been getting these messages for quite some time now. I did not know it was spam but I knew that my friends were not sending it. What makes it pretty obvious is the fact that the same message pops out from everyone's chat."

Cyber expert Rohit Srivastav from ClubHACK briefed MiD DAY about the preventive measures that users should take to prevent or avoid the spam messages. "Resist the urge to click on such links. Have fun, but also exercise caution. It's an open platform and attackers are getting smarter everyday," Rohit said.

 Police Inspector Dr. Sanjay Tungar, from the Cyber Crime Cell said "Many a time, users unknowingly share their personal information while registering for any application. The spammers collect email ids from such networks and send malicious links to them. The best way to avoid this is to religiously avoid clicking on the links and just close the chat window. If possible cross-check with your friends to verify whether they have really sent the link to you."

Facebook Apologizes For Censoring Gay Kiss Photo

Two men kissing: too risque for Facebook?

Censoring Gay Kiss
The social network recently removed a picture of a gay kiss for allegedly violating its terms of use, which state, "You will not post content that: is hateful, threatening, or pornographic; incites violence; or contains nudity or graphic or gratuitous violence."

The photo in question (see it here) accompanied a Facebook page calling for a "kiss-in" protest for an incident at a pub, where a gay couple was ousted for kissing (the landlady deemed the act "obscene").

Facebook has since re-instated the page, and apologized for the error in a statement.

"The photo in question does not violate our Statement of Rights and Responsibilities and was removed in error," the statement read.

The removed picture, a promo pic from the soap opera Eastenders, contained no nudity or graphic sexuality, but the event has sparked outrage from users wondering why a photo of two fully clothed men engaging in a kiss would be flagged. Already, Facebook pages have been set up where users have flooded the feed with more pictures of same-sex kisses. A gay kiss-in to protest the act has also been organized.

Especially curious is the fact that Facebook does not remove every picture flagged as inappropriate. According to them, a "Facebook administrator looks into each report thoroughly in order to decide the appropriate course of action. If no violation of our Statement of Rights and Responsibilities has occurred, then no action will be taken," suggesting that a person, not a program, may have removed the picture.


"Facebook has said that it was a mistake to remove the picture," reads a post from the event protesting the removal. "Mistake or malicious, it shouldn't have happened. Many people have been affected."

Facebook also ran into trouble when they recently removed a photo of the 1866 painting "The Origin of the World" by Gustave Courbet, which is a representation of female genitalia, and deleted the user's account. The man is now suing the site for causing him to miss messages on the eve of his birthday. Facebook previously removed the same painting, and deactivated the accounts, of two other users: a Danish artist whose profile was reinstated on the condition that he post no more nudes, and a French writer who changed his profile picture to the painting in support.

Facebook makes money from user's data

Social networking site Facebook is using its users’s profile, status updates, messages and other information to help advertisers find exactly who they want to reach out to.

Facebook
Facebook is now tracking this activity, shooting online ads to users based on their demographics, interests, even what they say to friends on the site sometimes within minutes of them typing a key word or phrase.

For example, women who have changed their relationship status to “engaged” on their Facebook profiles will receive ads from local wedding planners and caterers when they log in.

Middle-aged men who list motorcycling as one of their hobbies could get pitches from Victory Motorcycles.

According to the Los Angeles Times, some analysis believe that Facebook’s unique trove of consumer behavior could transform it into one of the most powerful marketing tools ever invented.

However, privacy watchdogs say Facebook’s unique ability to mine data and sell advertising based on what its members voluntarily share amounts to electronic eavesdropping on personal updates, posts and messages that many users intended to share only with friends.

Facebook’s first experiment with paid ads was a flop. In 2007 it rolled out Beacon, which broadcast information on Facebook about users’ activities and purchases elsewhere on the Web without their permission.

Facebook pulled the program after settling a lawsuit brought on behalf of Facebook users.

This time around, company officials appear to be proceeding more cautiously. David Fischer, Facebook’s vice president of advertising and global operations, says Facebook delivers ads that are relevant to users’ lives.

“This is an opportunity for brands to connect with you. When someone likes a brand, they are building a two-way conversation, creating an ongoing relationship,” said Fischer.

World's first commercially available Jetpack goes on sale

At possible risk to the user's health, many a geek's dream is finally coming true. According to the Daily Mail, the world's first commercial jet pack will hit the market this year. Costing a cool $75,000, the jet pack is much more than the usual DIY projects we've told you about. That's right; it's not just a rocket strapped to your back!
Commercial Jet Pack Finally Real, Retails for $75K

The unnamed machine will be manufactured by Martin Aircraft Company at a rate of about 500 each year. To take flight, it uses a dual-fan propulsion system instead of a jet engine, but still manages to burn about 10 gallons of gas per hour, meaning that flight time is limited to about 30 minutes. On the plus side, the jet pack meets FAA Ultralight Regulations, weighing about 250 pounds and able to carry a 280-pound person to speeds as high as 60-mph. That FAA qualification means you won't need a pilot's license to operate it; after completing Martin's training program (and waiting for your check to clear), you can take to the skies. 

Don't worry, there are safety precautions. The jet pack has an internal roll cage, and a parachute that works at low altitudes (although, the jet pack has flown as high as 7,800-feet in tests). While it sounds safe, or as safe as a jet pack can be, we'll stick to more traditional modes of transportation. Flying is for the birds.

Doctors use iPod for knee surgery


In many ways, MP3 players have gone above their call of duty as music storing devices, and are often used to help bring criminals to justice, record flight data, etc. Now, they are being used to assist orthopaedic surgeons in knee-replacement procedures. For the first time in Asia, a city doctor on Wednesday performed a knee-replacement computer-assisted surgery on an elderly patient-with an iPod. 

The patient, 75-year-old Gulab Singhvi, had been suffering from severe joint pain in her left knee for the past four years. When she decided to undergo a knee-replacement procedure, little did her family realize that Singhvi would be the first person in Asia to undergo the surgery with the help of an iPod navigation system. 

Dr Arun Mullaji, who performed the surgery at Breach Candy Hospital, said: "Though the computer navigation itself was a breakthrough, the iPod navigation allows for better accuracy." 

So how does it work? The hardware is made up of a special casing for the iPod as well as a computer system that communicates wirelessly with the device. The computing system also comprises a camera equipped with an infrared sensor. The casing has slots for miniature instruments and three antennae with reflecting spheres. These spheres provide a frame of reference to the camera's infrared sensor, which tracks each of them to plot the x, y and z axis of each point. (See Cutting Edge box). 

This system, which has been developed by Smith & Nephew Inc, works on a similar technology used in computer navigation systems. "The iPod is connected to a camera attached to a stand which is kept at a distance. Instead of a screen, which used to be at the same stand earlier, the surgeon can see the image along with other information on the iPod screen," said Tim Frandsen, director of global surgical navigation in the company. 

Mullaji added: "The iPod screen shows accurate measurements, angles, positions and the movement that will be possible for each point touched by the sensor pointer connected to it. And since the iPod is carried by us in hand, the screen is at the same area where the surgery is being done as against the screen at a distance in a computer navigation system."- 

In a replacement surgery, there's a 3 mm margin of error. If there is an error beyond this, the person may suffer multiple fractures and dislocations even after the surgery. "Studies prove that within the next 30 years, there is likely to be a 600% increase in the number of revision surgeries world over. The iPod navigation system helps in giving the alignment of the bone joint with 0.1 mm precision," said Mullaji.

10 things I hate about the internet

1.  Steve Jobs. Think of the most preening know-it-all you have ever encountered. Say, Pervez Musharraf. Now imagine if he was always right.

2. The constant reminder of my immaturity. As a pimply 14-year-old, you probably thought your lovelorn poetry deserved a wider audience. As a college freshman, you fancied yourself an astute political analyst. Congratulations, your ramblings are only a Google search (probably to be conducted by a prospective employer) away.

3. Fan boys and early adopters. Before the advent of the internet, it used to be easy to ignore those who claimed to love bands before they hit it big. No matter how hard you try, Linux scolds are impossible to tune out.

4. Online commenters. If people who write on the internet are the pond scum of humanity, those who leave comments on their posts are the algae.

5. The death of irony. Try and write something satirical. Then sit back and wait for everyone to take you literally. Irony has now been replaced by sarcasm. And as Neil Patrick Harris one said, “Sarcasm, how original.”

6.  Buffering. The internet is supposed to be all about instant gratification. Why, then, do I have to wait four hours for songs to load on YouTube? I want to spend my entire workday pretending I’m doing something other than listening to Bruce Springsteen, not just half.

7. Websites that use Flash. When I go to a restaurant’s website, I want to see an address, a menu and a phone number for reservations. Making me wait five minutes while a rabbit in a top hat dances across the screen isn’t going to help your business.

8. It’s yet another way to measure your self-worth. There is nothing worse than having fewer followers than anyone else on Twitter. Actually, there is: having fewer friends than everyone on Facebook.

9. The rise of inane lists like this one. The average internet-user has the attention span of a gnat. Information has to be bite-sized, numbered and not too taxing on the miniscule brain.

10. Justin Bieber. The internet made this alleged human famous. There is something seriously wrong with a 16-year-old whose voice hasn’t yet broken.

Fighting malaria with smartphone software?

A team of graduate students has created a new smartphone application they say will allow healthcare workers in remote locations to diagnose malaria cases on the spot.


But first, the students hope their application wins this weekend's Imagine Cup 2011 national finals in Seattle.

The 9th-annual Imagine Cup, sponsored by Microsoft, asks student entrants to "imagine a world where technology helps solve the toughest problems."

Tristan Gibeau, 25, a graduate computer engineering student at the University of Central Florida in Orlando, said his team's application fits the bill.

"It's going to make a difference in trying to contain the outbreak of malaria," said Gibeau, the project's software designer.

"In the big picture, it'll hopefully help in the fight against most diseases out there and make everybody's life a little easier."

His team's prototype is a Windows 7-equipped Samsung Focus smart phone modified with a microscopic camera lens.

Gibeau said the software application can take a picture of a blood sample, process the data to detect malaria parasites, quantify how much malaria is in the sample and point the parasites out to the phone user.

"It actually draws a red box around the clusters of malaria, and it actually notifies you how many it found," Gibeau said.

Although microscopic lenses are already available for smart phones, Gibeau said the software takes the concept's usefulness to another level.

It would enable a doctor or nurse working, for example, in an African village lacking Internet access to make a diagnosis without having to upload data for processing elsewhere.

However, once the data stored in the phone is uploaded, it can be used to spot disease trends, Gibeau said.

He said he is working on smart phone applications to detect sickle cell and other diseases and also plans to make the software easily adaptable to lab-based microscopes.

The smart phone application was the idea of team member Wilson To, a 25-year-old graduate student in comparative pathology at the University of California at Davis.

It builds upon a mobile microscope concept that To and a different team created to win last year's Imagine Cup national finals.

Mechanical SmartBird Seagull Flies Like a Real Bird - German Sciencetist

Earlier this week we took a look at the mechanical animals of the German engineering firm Festo. Now Festo has built the SmartBird, an avian robot that takes flight on bionic wings.











Festo explains:

  • This bionic technology-bearer, which is inspired by the herring gull, can start, fly and land autonomously — with no additional drive mechanism. Its wings not only beat up and down, but also twist at specific angles. This is made possible by an active articulated torsional drive unit, which in combination with a complex control system attains an unprecedented level of efficiency in flight operation. Festo has thus succeeded for the first time in creating an energy-efficient technical adaptation of this model from nature.


Yes, Bubo the owl from Clash of the Titans is one step closer to being a reality.

Google Introduces New 'Like' Button, +1

Google's got a "Like" button.

The company announced they will introduce a feature called +1, which lets you recommend any webpage or ad you like. The results will then begin to appear in search results.

For example, if you're searching for a tapas restaurant, some of the results may show you a +1 from one of your Gmail contacts, or how many other strangers have +1-ed the same site.

Google touts the "relevance" of the +1 system, which uses information from people you know, at the moment you are actively searching for specific content. Unlike, Google's targeted ads, +1 results are directly tied to the queries you search, rather than directed at you in the hope that you may be interested.

While your Google contacts will initially determine the +1's you see, Google may eventually incorporate recommendations from your Twitter contacts. In case you're wondering who Google thinks your buddies are, you can check out the "Social Circle and Content" section on your Google Dashboard.

In January, Google rolled out an update to its Social Search feature, which highlights content that has been either created or shared by those in your social network. Google +1 draws from the same Social Circle, but adds the recommendation layer.

Google's +1 feature resembles Facebook's "Like" button. And +1 also brings the social layer to ads--something Facebook already implements, and somewhere the two companies draw massive revenue from. Advertisers will not be able to turn them off, though they will be able to see the statistics Google compiles.

To enable +1, users need to create a Google profile, or upgrade an existing profile. This account compiles your history of +1s and lets you delete them at will. Though not everyone will see +1 at first, users can opt-in earl

7 Reasons Not To Buy An iPad 2

The iPad 2 went on sale in the U.S. on March 11, and already the device is selling out at Apple, AT&T, Verizon and various retail stores around the country.

Industry analysts are predicting that the device will outsell its predecessor, but that doesn't mean you should rush out and get one right away.

Take a look at 7 reasons why you should think twice before snapping up this shiny new tablet, and share your thoughts in the comments (below).

You can also check out our list of 7 iPad alternatives to get a feel for the iPad's competition. For more information about the iPad 2, browse our overview of the iPad 2's features and read what critics said about the tablet.

It May Be Obsolete Soon
It May Be Obsolete Soon

The day before the iPad 2's debut, an anonymous Apple employee allegedly came forward with the news that iPad 2 will be overshadowed very soon not by another tablet, but by the iPad 3. "[T]he third-generation iPad is the one to make a song and a dance about," the staffer said, according to Cult of Mac. Some are predicting that the new tablet may launch as soon as the fall of 2011.


There's No 4G Option
There's No 4G Option

With AT&T and Verizon updating their networks to the latest wireless standards, it seemed possible that Apple would lunch the iPad 2 as a 4G device. Like the original iPad, though, the iPad 2 is equipped only for 3G speeds. Meanwhile, rival tablets like the BlackBerry PlayBook, the Motorola Xoom and the T-Mobile G Slate were built to be 4G-capable devices. 

Complex Data Plans
Complex Data Plans

If you opt for a 3G version of the iPad 2, you've got two carrier choices: Verizon or AT&T, both of which offer tiered data pricing plans that can make the average consumer's head spin. "Determining how much you'll pay depends heavily on how much data you think you'll use," writes CNNMoney.com. "Go over that limit, and you could be shelling out a lot, depending on your plan." 

While AT&T previously offered an unlimited data plan for the original iPad, that option has been all but phased out. If you're an AT&T customer who bought an iPad 3G last year and retained your unlimited data plan, the carrier will allow you to transfer that plan to your new iPad 2. However, customers who are new to AT&T (and Verizon, for that matter) won't have the option of unlimited data at a fixed price.

It's Large For An E-Reader
It's Large For An E-Reader

With its iBook library and its wispy form factor, the iPad 2 (like the iPad 1 before it) crowds into the territory of e-readers like the Amazon Kindle, which Forrester predicts will be the only device that will truly compete with iPad 2 in 2011. However, reviewer Walt Mossberg of All Things D and the Wall Street Journal found that the iPad 2 cumbersome to hold and read. "Despite being slimmer and lighter, the iPad 2 still has roughly the same length and width as the original, so it can't compete with the Amazon Kindle, or the smaller seven-inch tablets, if you're trying to juggle it while standing in a crowded subway," wrote Mossberg. 


Subpar Cameras
Subpar Cameras

Though the iPad 2 includes both a front-facing and a rear-facing camera, Apple didn't boast about the webcams' resolutions. (In fact, the camera specs on Apple's website are pretty vague.) Reviewers found that the new additions produced mediocre videos and poor-quality photos. Writes Josh Topolsky for Engadget,
At the end of the day, the company is putting its flag in the ground when it comes to tablets with cameras, but it feels like it's done the bare minimum to make it happen. We won't lie: we're disappointed by how low end these cameras feel.

Its Price Tag
Its Price Tag

It's impressive that Apple was able to pack new features into the iPad 2's slimmer frame while keeping the price the same as last year's model, but that price tag is still not accessible to everyone. The iPad 2, like its predecessor, is intended more as an accessory to than a replacement for a primary computing device. Even though the iPad is cheaper than competitors like the Motorola Xoom, many potential customers may hesitate to shell out a minimum of $500 for a device whose functions exceed those of an e-reader but fall short of most laptops.

No Flash
No Flash

As with Apple's other mobile products, iPad 2 doesn't natively support Adobe Flash player, which means that the device will will load many websites only partially and won't play Flash-based videos. If you can't live without your Vevo or Hulu fix, you can download apps like SkyFire and iSwifter to enable Flash videos on your iPad 2. As for the competition, Motorola has rolled out a software update to make the Xoom tablet a Flash-ready device.

NASA Finds Cocaine At Space Center - AGAIN

NASA is investigating after cocaine was found in a facility at the Kennedy Space Center in Florida.
Cocaine
NASA spokesman Allard Beutel said Tuesday that 4.2 grams of a white powdery substance was found last week at the NASA facility, though he would not say where.

It tested positive for cocaine.

It's not the first time cocaine has been found at the space center.

A small amount was discovered in January 2010 in a secure part of a hangar that housed space shuttle Discovery. A spokeswoman from NASA's Inspector General Office in Washington declined to comment on how that case was resolved.

Facebook to share users details


Facebook To Share Users' Home Addresses, Phone Numbers With External Sites
Facebook to share

Facebook will be moving forward with a controversial plan to give third-party developers and external websites the ability to access users' home addresses and cellphone numbers in the face of criticism from privacy experts, users, and even congressmen.

Facebook quietly announced the new policy in a note posted to its Developer Blog in January. It suspended the feature just three days later following user outcry, while promising that it would be "re-enabling this improved feature in the next few weeks."

In response to a letter penned by Representatives Edward Markey (D-Mass.) and Joe Barton (R-Texas) expressing concern over the new functionality, Facebook reaffirmed that it will be allowing third parties to request access to users' addresses and phone numbers.

Facebook noted that it is considering implementing controls that would more explicitly highlight the personal nature of the information being transmitted to applications and explained it is "actively considering" whether to restrict users under 18 years old from sharing their contact information with third-party developers.

"We expect that, once the feature is re-enabled, Facebook will again permit users to authorize applications to obtain their contact information," Facebook's Marne Levine, vice president of global public policy, wrote in the letter to Reps. Markey and Barton. "[H]owever, we are currently evaluating methods to further enhance user control in this area."

Facebook has attempted to tread a fine line with regard to privacy issues even as it has continuously pushed users to share more information, both on Facebook and beyond the social network.

The plan to open up users' address and phone numbers to third-party sites and services marks the latest frontier in Facebook's often controversy-fraught efforts to encourage users to be more liberal in sharing their data and online activity.

Even if the revamped feature were to include improved notifications and protections for minors, privacy experts warn the feature could imperil users' personal information and increase their risk of being targeted by scams, spam, and identity thieves.

Though Facebook prohibits applications from selling users' information or sharing it with advertisers and data brokers, malicious, rogue apps spreading phishing scams and other ruses are not uncommon on the social network. With just a few errant clicks, an unsuspecting user could potentially hand over her home address to a scammer peddling diet cures or free iPads in an effort to compile credit card data and other personal information.

"[Scammers] might be able to impersonate you if they had your phone number," said Norman Sadeh-Koniecpol, a professor at the Carnegie Mellon School of Computer Science. "They're saying, 'Please give us your phone number,' but they're not telling you whether they'll share it or whether they'll sell it or use if for malicious purposes. In fact, you don't know who you're dealing with."

Others are concerned with what they see as Facebook's willingness to change the rules of play--first encouraging people to share personal information with a more limited group of friends, then allowing that data to be accessed in new, unexpected ways.

"People never thought when they were posting this data [such as their phone numbers] that it would be accessible to anyone but friends. There's a real mismatch of expectations around that," said Mary Hodder, chairman of the Personal Data Ecosystem Consortium. "Even if Facebook comes back with new protections, they're still saying, 'Hey, get over it, your data is public.' I feel sad for users that Facebook's approach is 'You give us anything and it's all fair game.'"

Despite the social network's intentions to make addresses and phone numbers accessible to developers, Rep. Markey offered Facebook measured praise for its response, while stressing the necessity of protecting younger users.

"I'm pleased that Facebook's response indicated that it's looking to enhance its process for highlighting for users when they are being asked for permission to share their contact information," Rep. Markey said in a statement. "I'm also encouraged that Facebook is deciding whether to allow applications on the site to request contact information from minors. I don't believe that applications on Facebook should get this information from teens, and I encourage Facebook to wall off access to teen's contact information if they enable this new feature."

The End Is Near For Netbooks

If the fact few people are buying netbooks nowadays isn't enough, Acer sales manager Lu Bing-hsian has gone on record as saying that tablets will soon replace netbooks in Acer's line-up. "That's the direction of the market," he says.

It's hard to argue. The recent Consumer Electroincs Show saw lots of tablets being launched and the netbook hype is well and truly over. Thankfully.

I've been waiting for this moment since late 2007. That's when I took receipt of the first ever netbook, an Asus Eee 701. I was among the first in the world to own one, having placed an order well in advance.

The eagerness with which I tore open the packaging was destroyed within minutes of booting up. It was a horrible user experience. I developed a hand cramp within half an hour from typing on the tiny keyboard. The touchpad was laughably small--like sliding your finger around on a postage stamp. The screen was too small to do anything useful.

It just didn't work. It was a failure. I tried very hard to like it, hoping my issues would go away, but it was hopeless. I sold the netbook within a month (thank you eBay!). However, I clearly hadn't learned a lesson because in 2009, I bought another netbook: a Dell Mini 9. An initial honeymoon period ended pretty quickly and the same issues returned, including the hand cramp and uselessly small screen.

Like all netbooks, the Mini 9 was unusable for anybody but a small child or somebody with small hands and a lot of patience. True, some people loved them. Others managed without too many issues. Most people, like me, bought them and realized they'd made a mistake, before putting them on a shelf to collect dust.

Nobody admitted this. It felt like a lot of the technology press were waiting for the design limitations to be magically somehow ironed out. But that never happened.

I came to the conclusion that the netbook form factor simply doesn't work. Or, rather, it would have worked fine if manufacturers had done something other than merely given us shrunken laptops. If they'd actually thought about the limitations of the small form factor and made creative and intelligent design decisions, it might have been a different story.

Part of the trouble was that manufacturers saw netbooks as a way to sell cheap computers. As far as they were concerned, it was always about tapping into a market that couldn't afford full-blown laptops.

From a consumer point of view, we wanted ultraportable computers, but ones that didn't sacrifice usability. Price was an issue, as it always is, but manufacturers didn't always need to drop to bottom dollar prices. A few dollars added to the ticket price, but invested in better design, would have paid dividends.

For example, netbook software was uniformly poor quality. Linux and Windows were fine on larger computers but on small computers a "full" OS didn't make sense. A new operating system was required, not an adapted one.

Web browsing needed to be rethought. Including a standard Web browser was mindless. With its toolbar and status bar, browsers chewed up screen real estate and left little actual space for Web pages. I'm not a user interface (UI) designer but wouldn't it have made more sense to move all that over to the left or right-hand side? Most of netbook screens were essentially wide-screen, and few Websites demand a wide view.

To see how things could have been done, we need only look at tablet computers. As with netbooks, we again have the same old computing hardware in a new form factor. But Apple's iOS and Google Android make all the difference. They're operating systems specifically designed to work on this kind of device. Intelligent decisions have been made. Web browsing is a dream, not a nightmare.

However, netbooks undeniably gave the world one thing: they introduced the concept of people owning more than one computing device. We forget that, back in 2007, only geeks owned more than one computer. Most of us relied on a single computer, whether that was a desktop or a laptop.

Netbooks showed how we could spread our digital lives across a number of computers. The tablet and smartphone revolution that's happening right now couldn't have begun without netbooks clearing a path.

So perhaps I should be thanking netbooks, rather than gloating over their demise.

If nothing else, they showed how not to do things.

Old Apple Mac and iPad recycled as an awesome DJ helmet


It takes a unique sense of style to get noticed as a club DJ these days, so LA based DJ Kid Chameleon and his friend Terrence Scoville created this visualizer helmet from an old Apple Macintosh Plus, a bicycle helmet, an iPad, and an electroluminescent display.

The whole shebang is controlled by a iMac running Resolume Avenue, a MIDI keyboard, with a Wiimote in there somewhere for good measure.

At 45 seconds into the video you can see the momentous occasion when he puts on the helmet for the first time, to the strains of the theme from 2001: A Space Odyssey.

Top four cyber threats for 2011 revealed

From Internet superweapons to Facebook crimes, security experts have predicted some new web attacks for 2011. Here are the top four security concerns that cyber experts see coming over the digital horizon:

Cyber War's newest superweapon: Stuxnet and Copycats

Stuxnet was first discovered in July 2010 by a security firm in Belarus, but made headlines only when Iranian state media announced the Middle East nation had been the target of a coordinated attack.

"The idea that a piece of malicious code can target physical systems and create real-world impacts is something that's been speculated in the industry for quite some time and certainly was largely understood to be possible," ABC News quoted Ben Greenbaum, senior research manager for cyber security firm Symantec, as saying.

When Hacktivists attack

Another recent online development that experts expect to see increase in 2011 was played out on an international scale at the end of 2010.

Shortly after the information sharing website WikiLeaks published a portion of over 250,000 classified U.S. diplomatic documents, the website's founder, Julian Assange, was arrested on sexual assault charges. While he was in custody in England, some major financial institutions including Mastercard, Paypal and Visa discontinued a service that was helping to raise money for Assange's defense.

Wikileaks' supporters shot back in an unprecedented manner: nearly 50,000 people downloaded simple programs used to launch a massive denial of service attacks against the companies they deemed at odds with Wikileaks.

The loosely organized "hacktivists" managed to take down the web pages of several of their targets, and their spontaneous attempt may be the first major showing of a new way to express political beliefs at a grassroots level.

Cyber security firm McAfee predicts in a new paper that not only will politically motivated attacks be "far more numerous in 2011," but also the company said brand new kinds of attacks would appear.

Mobile devices: Two ways for criminals to take advantage

On a more personal level, experts warned that as more and more people own internet-capable mobile devices in 2011, they're also increasing their exposure to cyber and real-life criminals.

First, McAfee showed that the GPS functions on many smart phones that allow users to tell their friends where they are via Facebook and Twitter also tell criminals exactly where they are-and where they are not.

"It then becomes child's play to craft a targeted attack based upon what the bad guys have just learned from these services," McAfee said.

While this is not a new phenomenon, McAfee reported mobile tracking will be a "huge focus for cybercriminals and scammers in 2011 and beyond."

Second, both Security News Daily and Symantec list the technical vulnerabilities of mobile devices on their list of dangers for 2011.

Spammers Adapt to Social Media

Finally, experts said 2011 is going to see a change in perhaps the most annoying security concern online: spammers.

A curious thing happened in Dec. 2010: Normally the amount of email spam would be at its highest levels during the holiday season, but instead it dropped dramatically, according to a study by web security provider Commtouch. Part of the reason, McAfee said, is that spammers are altering their strategy.

Rather than bombarding users with countless emails, they bombard users through social networking sites-with multiple links and requests from programs like Facebook and Twitter-attempting to trick users including clicking on links to malicious code.

"This shift will completely alter the threat landscape in 2011," said McAfee.
