Sure there are tons of great/better chess games you can play online with your friends, but this built-in one is accessible to everyone you know on Facebook.


11 Inventions That Could’ve Changed The World If Only Greed Hadn’t Set In

We could really have been living in a different world right now. A world with a lot more harmony among mankind. A world with a lot less conflict. A happier world for sure. But that wouldn’t have been profitable for some, now would it?

Before you call me cynical, here’s a list of 13 inventions that could have revolutionised the way we live but didn’t. Because greed came in the way.

1. General Motors EV1



EV1 was the world’s first mass-produced electric car. The decision to mass-produce an electric car came after GM received a favourable reception for its 1990 Impact electric concept car, from which the design of the EV1 drew heavily. This single-speed reduction integrated with motor and differential, a 2-door coupe was in production between 1996-1999, producing a total of 1,117 units.

The car was discouraged, and supposedly discontinued, after oil companies started showing their displeasure and discouraging manufacturers. Unfortunately, General Motors destroyed most of the units, and discontinued the car.

2. Project XA

Project XA


Project XA was a long-term project by the Liggett group. Liggett spent around $15 million and 12 years of research to come up with cigarettes that were considerably safer than conventional cigarettes. These cigarettes would have most carcinogens removed, which would reduce the harm done by tobacco and its by products.

Other tobacco companies didn’t like the implication that their tobacco was harmful. Defendant Brown & Williamson threatened Liggett’s “very existence” if it marketed the cigarette. Later R. J. Reynolds told the FDA that it was because the tobacco industry wanted to put across that “conventional cigarettes weren’t unsafe”. Calling one safer than the other would put their business in jeopardy.

3. Cold Fusion

Cold Fusion


Cold fusion describes a form of energy generated when hydrogen interacts with various metals like nickel and palladium. Which, in layman terms, stands for a nuclear reaction that would occur at, or very near room temperature. That would mean a very high possibility of a cheap and abundant source of energy at one’s disposal.

Apparently, a number of failed experiments led to rival scientists and other members in the fraternity branding it as junk science. Even though funding for further tests in cold fusion is very hard to obtain, a small number of researchers continue to investigate the theory.

4. The Chronovisor



This, if true, has to be one of the most insane inventions that got lost in time. Father François Brunes, the author of several books on the paranormal and religion, in his 2002 book Le Nouveau Mystère du Vatican (“The Vatican’s New Mystery”) talks about the Chronovisor. The Chronovisor was apparently a fully functional device with which one could see, or hear things from the past! In the book, Brunes mentions that the device was built by a certain Pellegrino Ernetti, an Italian priest and scientist. Described as a large cabinet with a cathode ray tube for viewing the received events, and a series of buttons, levers, and other controls for selecting the time and the location to be viewed, it worked by receiving, decoding and reproducing electromagnetic radiation left behind from past events. It could also pick up the audio component or sound waves emitted by these same events. Ernetti said that he had observed, among other historical events, Christ’s crucifixion and photographed it as well. A copy of this image, Ernetti said, appeared in the 2 May 1972 issue of La Domenica del Corriere, an Italian weekly news magazine. The device being intriguing to say the least, but the existence, let alone the functionality of the Chronovisor was never validated. Some believe the device can still be found in the Vatican.

5. The Rife Beam

Rife Beam


Dr Royal Raymond Rife or Roy Rife, an American optics engineer, claimed to have invented a device that would have completely changed the health sector. The genius that many claim Dr. Rife was, engineered an electronic device in the 1930s that would destroy pathogens, bacteria, even viruses without leaving any toxic side effects. This meant that cancer, the life threatening disease that it has become off-late would have been as easy to cure as a common cold. The beam could completely destroy cancer by altering the cancer’s cellular environment or by killing cancer viruses with an electronic or ultra sonic beam.

You could probably guess exactly what happened next. The cancer cure industry is a multi-billion dollar one which wouldn’t have been so had the beam reached the public. Dr. Rife claimed that the American Medical Association, with pressure from the medical mafia discredited his life-saving device. Currently only a handful of doctors are holding this technology together, hoping that someday, it will save humanity.

6. Water Fuel Cell

Water Fuel Cell


American Stanley Allen Meyer came up with a Water Fuel Cell in which the cell splits water into its component elements, hydrogen and oxygen. The hydrogen would then be used to generate energy. According to Meyer, the device required less energy to perform electrolysis than the minimum energy requirement predicted or measured by conventional science. He claimed that this could revolutionise the automobile industry.

This theory, however, was found to be fraudulent by an Ohio court in 1996. But the suspicions surrounding his sudden death is what makes people think that his technology could have been suppressed.

7. The Cloudbuster



Designed by Austrian psychoanalyst Wilhelm Reich, the Cloudbuster was a pseudo-scientific device that could be used to produce rain by manipulating what he termed as orgone energy present in the atmosphere. Successfully tested in 1953, it was intended to be used like a lightening rod that would draw the orgone energy out of the atmosphere, causing the formation of clouds and rain. Famine wouldn’t have been a word that’s used so often in today’s day and age if a technology like this were to be made available.

Being a controversial figure, Reich was arrested, and all his works were destroyed.

8. Implosion Generators

Implosion Generators


Another device that could produce free energy based on implosion and water vortices was invented by Viktor Schauberger. But we couldn’t find a lot of information on the Austrian’s invention and his theory on vortex energy. Viktor’s invention was later buried by his U.S partners.

9. Wardenclyffe Towers



Scientist Nikola Tesla was one of the most interesting figures in history, with many of his theories and inventions being ahead of their time. His rise could have given birth to a number of world-altering technologies, but unfortunately that never happened. The Wardenclyffe Tower could have perhaps been the most important one. He attempted to provide free energy to everyone across the globe by harnessing electricity from the Earth’s ionosphere by means of towers. Without wires, the towers could transmit the harnessed electricity to ground-level areas requiring it.

But what’s a world if people can’t mint money out of a path-breaking product right? The thought of giving every individual across the globe free electricity didn’t go down well with the douchebags in power. Tesla’s  funding was stopped. His equipment and lab was burned down together with the related intellectual property because it posed a threat to undercutting the cost of the conventional electricity grid system. Tesla, who could have been the most important man in human history, died a poverty-stricken, lonely and forgotten man in New York.

10. The anti-gravity device

Anti Gravity Device


Thomas Townsend Brown developed discs that used electrogravitic propulsion to build devices that could defy gravity. But what happens when something too good to be true comes along the way? It becomes classified information and is shoved into rubble. That’s exactly what happened with Brown’s experiments as well. The results of his study were so impressive that it never saw the light of day.

11. The Unified Theory

Unified Thoery


Linus Pauling and Matthias Rath worked together to come up with a unified approach to curing heart diseases. Following a brilliant study, they found that heart disease is a result of a long-term vitamin C deficiency. The solution was to treat patients with frequent high doses (e.g. 6g/day) of vitamin C while using the amino acids lysine and proline to remove the atherosclerotic plaque lining the inner walls of the blood vessels, that cause blockages, thereby restricting blood flow and cardiovascular disease.

But I’m sure you can see why we don’t see it in practice. It was a financial threat to the pharmaceutical industry. A highly successful cheap alternative therapy is not good for business at all.

How to customize the URL of your LinkedIn profile

How to customize the URL of your LinkedIn profile

Before customizing the URL of your LinkedIn profile, it’s best to ensure that all vital information is posted since it serves as your online resume. Think of the name that you wish to use in your URL. It must be composed of 3 to 30 numbers or letters. Special characters and spaces are not accepted.

    1. Log in to your LinkedIn account.
    2. Hover your mouse on “Profile”, which can be found on the top part of the screen, then click “edit profile”. (See Image Below)
    3. LinkedIn URL Settings

    4. Look below your photo and you’ll see your profile’s URL. Click the “edit” link next to it. (See Image Above)
    5. Under “Your public profile URL” on the lower right side of the window, click the “customize your public profile URL” link. (See Image Below)
    6. LinkedIn URL Settings

    7. Enter your preferred URL name in the field. (See Image Below)
    8. LinkedIn URL Settings

    9. Click “Set Custom URL”.
    10. LinkedIn URL Settings

    That’s how you customize your LinkedIn URL. For instance, if you entered “ChaNarula”, your URL will be “http://www.linkedin.com/in/ChaNarula“. LinkedIn URL can only be customized up to three times within six months. If you’ve changed it three times in less than six months, you must wait for the said period to pass before you can change your URL again.

Heartbleed Hitlist: What Password Should You Change

An encryption flaw called the Heartbleed bug is already being called one of the biggest security threats the Internet has ever seen. The bug has affected many popular websites and services — ones you might use every day, like Gmail and Facebook — and could have quietly exposed your sensitive account information (such as passwords and credit card numbers) over the past two years.

But it hasn’t always been clear which sites have been affected. Mashable reached out to various companies included on a long list of websites that could potentially have the flaw. Below, we’ve rounded up the responses from some of the most popular social, email, banking and commerce sites on the web.

Some Internet companies that were vulnerable to the bug have already updated their servers with a security patch to fix the issue. This means you’ll need to go in and change your passwords immediately for these sites. Even that is no guarantee that your information wasn’t already compromised, but there’s no indication that hackers knew about the exploit before this week.

Although changing your password regularly is always good practice, if a site or service hasn’t yet patched the problem, your information will still be vulnerable.

We’ll keep updating the list as new information comes in.

What Comes After 4G

What is 5G

What Comes After 4G?

Wait wait wait, we’re talking about 5G mobile data now?! Ugh, but we just got 4G squared away. In any case, the ball is already rolling on the next generation of cellular technology, so we might as well figure out what in the hell IMT-Advanced is.

IMT-Advanced is the prototype of what 5G mobile broadband will be…

IMT-Advanced will not be the next mobile data technology that Verizon or Sprint or AT&T try and sell you. It’s what the WiMAX’s and LTE’s of the world will look to when jockeying to become the next mobile data spec. IMT has been one of the most influential organizations in developing mobile broadband standards over the past couple of decades, and now that they’ve put the finishing touches on their IMT-Advanced spec, that trend will continue. Think of it like those proto-cars at auto shows; you’ll see them someday, but they’ll go through some changes before hitting the road.

…brought into existence by the same people who created WiMax and LTE…

Two current standards are currently approved by IMT as meeting their Advanced spec: WirelessMAN-Advanced and and LTE-Advanced, which are based off the pre-existing WiMax and LTE technologies. LTE-Advanced is the obvious front runner, but you never know what could happen between now and then.

…that will promise faster data transfer speeds of 4G…

This is probably the least surprising part of 5G IMT-Advanced. It will be faster than 4G LTE and WiMAX. Both WiMax and LTE both promise theoretical download speeds over 100 Mbits/second. IMT-Advance technologies will have a theoretical max of 1 Gbit/second. Daily Trends says you’ll theoretically be able to download a 720p TV show in 90 seconds or less. FAST.

…fewer dead zones…

IMT-Advance technologies will not only to be able to allow more connections at each individual cellular hub, but will facilitate seamless handoffs when moving from one hub to another. Hopefully, that means good things for cities such as SF and NYC, which are affected both by heavy clusters of smartphone users and signal killers that are tall buildings.

…and could mean the end of data caps…

More bandwidth means less stress on the networks of mobile providers. Less stress on mobile networks means less of a need to impose data caps on consumers. If IMT-Advance delivers on its promise, we could see upward aspiring companies become competitive by racing to lift data caps.

…as early as 2014.

The earliest implementations of IMT-Advanced could arrive in a couple of years, as Daily Trends ponts out, but it’ll be longer than that before you see national coverage and a solid ecosystem of handsets. 4G LTE just grew into its own shoes, which came roughly four years after 3G did the same. Still though, how do you not get excited about 5G?!

HabitRPG Turns Better Behavior into a Game of Survival



HabitRPG takes the tasks you want to complete, however simple or complex, and turns them into a role-playing game where you earn experience points, gain levels, and stay alive by getting things done.

HabitRPG takes habits that you want to build and gives you experience points for completing them. If you fail at a habit, you lose health points. You can also add single to-do items that you simply check off a list to gain experience. If you lose all your health, you lose the game of HabitRPG. If you gain enough experience, you’ll get to the next level and your health will be restored. You also earn gold points for completing tasks and making positive progress on your habits, which you can use to (figuratively) purchase items like weapons and potions from the store to help you on your journey.

HabitRPG is free to use/play and available to all platforms via the web. HabitRPG also wants to become a mobile app, but needs funding to get there. You can help by backing the project on Kickstarter if you’re interested.

Why do Hard Drives have less capacity than advertised?

Pile of Hard Drives

My friend recently bought a 1TB external hard drive and complained that he got ripped off. Upon questioning him, I found out that his 1TB hard drive had only 920-ish GB.

The first thing I did was check if there was anything on the hard drive and found some bundled software, tutorial videos and user manuals in all imaginable languages on the drive. I went back to My Computer, right clicked the drive and formatted it.

After formatting the drive we still end up with less than 930GB of available space which did seem like a rip off as more than 70GB or 7% of the capacity was missing.

I went ahead and tried to find the reason for this loss of capacity and found that there was a difference in the way hard drive capacity was calculated by the manufacturers and the computer.

While the manufacturer counts 1TB as 1000GB, 1GB as 1000MB and 1MB as 1000kB, computers do it different, for them 1MB is 1024kB, 1GB is 1024MB and 1TB is 1024GB.

So here’s the maths

1000 x 1000 x 1000 x 1000 = 1,000,000,000,000kB

(((1,000,000,000,000  / 1024) / 1024) / 1024) = 931.32 from which around 69GB seems to be missing.

This clearly explains the missing capacity and thus answers all of who have noticed this difference in capacity.
