If You Use Facebook At All, You’ve Been Experimented On

Are you a regular Facebooker? Have you used it at all? Even a little bit? Maybe you are a faithful, every day (multiple times a day, of course) user, or maybe you only log on a couple times a week at most just to see what’s going on with all of your “friends”. Whatever the case, however much or however little you use Facebook, one thing seems to be true: at some point or another you have been part of some kind of Facebook experiment. In other words, without you even knowing about it, you’ve been a test subject for Facebook. You’ve been a lab rat, and you haven’t even seen the spinning wheel they had you running on while the powers that be watched you and compiled notes for discussion later.

Now, the big “experiment” that’s recently been revealed concerns Facebook’s manipulation of several thousand news feeds over a week period a couple years ago. Facebook wanted to see what people would do if they saw only positive news stories vs. if they saw only negative stories. While that may not sound like a huge deal, there are a lot of people who are now upset about it because they had no idea they were part of any kind of an experiment


Now, before everyone freaks out wondering what kind of testing they’ve been a part of, we should all probably take a collective deep breath and calm down for a moment.

A former data scientist for Facebook, Andrew Ledvina, worked for the social media giant until 2014. He talked to a reporter and let loose some things he probably wishes he would’ve kept to himself for a little longer. Here was the big one for me: “Experiments are run on every user at some point in their tenure on the site.”

What are those experiments? They’re probably not as earth shattering as the news feed manipulation story, but they consist of little things such as various text sizes, ads, and different buttons, etc.

But here’s the thing – every single user (according to the ex-employee) has been part of an experiment at some time or another. Maybe it was a small one, like the above examples, or maybe it was a big one. But how will they ever know? They probably won’t.

What are your thoughts? Are you okay with being part of Facebook’s endless experiments? Let us know your thoughts regarding this story in the comments section below!

How To Defragment Your Hard Disk Using Defraggler

When you make changes on your PC, the data is stored on your hard disk.  Anything you are likely to do on your PC, such as using copy, paste, delete and even saving files will result in disk fragmentation.  The files that you modify are stored in a separate segment on the hard disk from the original file location. This is where, over a period of time, your system can slow down and become unresponsive, because your computer is looking in different places to open a file.


A great tool for defragmenting your hard drive is Defraggler.  It is a free application that offers you various different options to defragment the hard disk. The application is actually better than Windows’ native defragmentation tool!  When you open Defraggler, if you navigate to Settings and then Options, you will find plenty of different options to tweak. You can exclude certain files from being defragmented.  This can be done according to drives, folders, file or file type.  If you want to, you can also schedule the defragmentation to occur at a particular time daily, weekly or monthly.
To start off,  you need to inform Defraggler which drive you want to scan (usually C:) and click the Analyze button.  This will check to see if you actually need to defragment your disk.  The results are displayed in a Drive Map graphic and text.  If the drive needs to be defragmented then just click the Defrag button to begin the defragmentation process*.  You will see the progress in the Status section.  Once the process is complete, you can restart your computer with a freshly defragged hard drive.  That’s it!

*During the defragment process your computer will slow down.

BlackBerry cuts prices of QWERTY handsets

Canadian handset maker Blackberry on Wednesday slashed prices of its QWERTY devices-9320, 9720 and Q5-by as much as Rs 6,000 to sell them for Rs 9,900 onwards.

The price of 9320 has been cut by 10 per cent from Rs 11,000 to Rs 9,900, while 9720 will be available for Rs 11,990 (from Rs 15,990 earlier).
BlackBerry 9320 is the first 3G enabled device from the smartphone maker's portfolio in the sub-Rs 10,000 range.

The Q5 will now be available for Rs 13,990, cheaper by almost 30 per cent from the earlier price of Rs 19,990.

Commenting on the price cut, Sameer Bhatia, Director (Distribution) at BlackBerry India said, "The classic BlackBerry keyboard has huge fan base who swear by the distinct typing experience that BlackBerry offers."
These compelling price-points will enable QWERTY fans to experience the latest technology and ease of use in one device, he added.

The offer will run across all BlackBerry retail networks.

The company had earlier slashed prices of its devices like Z30 and Z10 under special offers, which saw phenomenal response, often resulting in stocks running out.

Now, an app that pays you for exercise

Will you miss your workout if you had to pay for it? If money motivates you more than fitness, an app is here to either reward or punish you.
Pact is an app which uses money to track your fitness goals.

When you set up Pact, you give your credit card or Pay Pal information.
You also have to set your fitness goals like a pledge to workout a certain number of times in a week or eat healthy and Pact makes it specific.
Now enter a set distance you have to run. You must also decide the penalty you are willing to pay if you miss the workout.

The minimum penalty is $5 (Rs.300). The app tracks you when you check into a known gym and monitors how long you stay.

You can also wear a fitness band or use your phone's GPS to log miles. Reward money comes from people who failed to honour their pact, media reports said.

6 OF10 Optical Illusions That Will Blow Your Mind!

6.Count The Black Dots

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

Count The Black Dots

So you think you can see black dots? See if you can count them. You might struggle because the reality is, there are no black dots! There is in fact only white spots which seem to turn black from your peripheral vision.

7.Parallel Lines - Yes Or No?

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

Parallel Lines - Yes Or No?

Although it might not look like it, these lines are parallel. It is due to a brain function known as irradiation, where our brains tend to "spread" dark zones into light zones.

8.Which Is The Biggest Line?

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

Which Is The Biggest Line?

The answer: They are both the same size.!

9.Which Is The Biggest Orange Circle?

Which Is The Biggest Orange Circle?

 Again, they are both the same size. Known as the Ebbinghaus Illusion. 

10.Colouring In

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

Colouring In

We all love to colour in and so does our brain. When a polygon has a border made of a bright line, bordered by a darker line of a complementary color: your brain is tricked into "filling in" the shape with the brighter color.
 






5 of 10 Optical Illusions That Will Blow Your Mind!

1.How Many Legs Does An Elephant Have?

How Many Legs Does An Elephant Have?

Normally four but this particular elephant appears to have more. However have a really good look and you'll see the true nature of this image.

2.This Is Not A GIF!

 Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.


This Is Not A GIF!

Honestly, this is not an animated image. If you stare at just one area of the image you will see that it stops moving.

3.Coffee Beans

 Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.


Coffee Beans

See if you can find a hidden man's face within the coffee beans. He is definitely there but you may need to have a good look. Although this isn't an optical illusion in the truest sense, apparently if you can find the face in under three seconds then it may be that "the right side of your brain may be more developed than most." (The right side of the brain is thought to be responsible for art, creativity, and imagination.) Cool!

4.The Spiral

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

The Spiral

 Although this may look like a spiral, this image is actually a series of concentric circles. Run your finger along the lines and see for yourself. The complicated background pattern tricks your brain into filling in what isn't really there.

5.Pink Or Green Dots

Our brain is a truly amazing thing, better than any super computer out there. However, our brain can be easily tricked into seeing things that aren’t really there! Put your brain to the test with these fun optical illusions.

Pink Or Green Dots

If you stare at the black cross in the middle of the image then you will see a green dot moving around the circle. Eventually the pink dots will seem to disappear and you'll be left with only a green dot going round. However, the reality is that the green dot doesn't really exist!

 


 


 


 

Cars Won’t Have Steering Wheels For Too Much Longer

When I think of a vehicle there are several things that come to mind right away, no matter who the manufacturer is. I think of seat belts, mirrors, steering wheels, headlights, turn signals, and the list could go on and on. In the coming decades, though, many of those mentioned items may not have a place in the vehicles of the future. We all know that self-driving cars are in our future, but just how much will those vehicles change the vehicles we’ve grown so used to over the years?

Well, according to a study done by the Institute of Electronics and Engineers, pretty much everything we know and love is going to change. Here are the big couple of changes, though – they say that in 20 years, cars won’t include rear view mirrors or…steering wheels. No steering wheels? How are we going to turn the car? Quite simply, we won’t be turning the car or doing anything else to the car while it’s in motion, because the car will be doing everything for itself. We will quite literally just be along for the ride.



Meet The Car Of The Future!

I can’t even begin to imagine a world where drivers have next to no control over what’s happening on the road. I’ve asked this before, but what happens to the self-driving car when it somehow malfunctions? Will they all include some kind of failsafe device which the human driver can access? Because if not, I can’t imagine that ending very well.

While I am excited at the future of autonomous cars, there are obviously a lot of kinks which will need to be worked out in the meantime. What do you think? Can you picture cars without the features we’ve all grown so used to?
