Li-Fi-like System intended to bring 100-Gbps Speeds Straight to Your Computer

Li-Fi-like System intended to bring 100-Gbps Speeds Straight to Your Computer

Soon you will get 100 Gbps speed into your computer with Li-Fi Like Systems

Earlier the data which was transferred to our computer was not accurate and had drops while travelling a long way to its final destination that is you.  The data which travelled in the form of light has certain drops in midway due to various reasons. Now, researcher believe it’s all over.

How would it sound if we take the light all the way to the computer or TV, projecting it through the air over the last few meters and only converting it to an electronic signal at the end? That sounds amazing isn’t. The researches at Oxford University is  working on the similar technique with a system that takes light from the fiber, amplifies it, and beams it across a room to deliver data at more than 100 gigabits per second.

Ariel Gomez, a Ph.D. student in photonics at Oxford University who describes the system in IEEE Photonics Technology Letters says that such indoor optical wireless probably wouldn’t replace Wi-Fi, but if compared with data rates of 3 terabits per second and up, it’s certainly amazing and could find its uses. Wi-Fi, by contrast, can give a maximum top speed of about 7 Gb/s. And with light, there’s no worry about sticking to a limited set of radio frequencies. “If you’re in the optical window, you have virtually unlimited bandwidth and unlicensed spectrum,” Gomez says.

So to use this feature, you need to install a base station on the ceiling of a room, which would project the light toward the computer and also receive data heading out from the computer to the Internet.

The transceivers should be mounted with a wide field of view to make the alignment task easier, because the device relies on wavelength division multiplexing, which splits the signal into slightly different colours of light.  Just like a prism, which diffracts the light into several colours, the diffraction grating of the beam steerer bends each wavelength a different amount. With a 60° field of view, the team was able to transmit six different wavelengths, each at 37.4 Gb/s, for an aggregate bandwidth of 224 Gb/s. With a 36° field of view, they managed only three channels, for 112 Gb/s.

The system requires a direct line of sight, and for now the receiver must be in a fixed position. The next step is to develop a tracking and location system so that a user could place a laptop at a random spot on a table and have the system find it and create a link.

The team which is working on this technology also included researchers from University College, London, accomplished this using so-called holographic beam steering at both the transmitter and receiver ends. These use an array of liquid crystals to create a programmable diffraction grating that reflects the light in the desired direction. The device is similar to that used in projectors, says Dominic O’Brien, a photonics engineer at Oxford who directed the work.

Brien is a member of the Ultra-Parallel Visible Light Communications project, with colleagues at the Universities of Edinburgh, Strathclyde, St. Andrews, and Cambridge.  Among several goals one of their goals is to develop LiFi, which uses the light that’s also illuminating a room as a way to send data signals. He says LiFi usually refers to schemes based on visible wavelengths of light, whereas this system relies on infrared light at 1550 nm, which is used in telecommunications.

All these technologies—Wi-Fi, Li-Fi, optical wireless—may wind up being part of how people link devices to the Internet. There is no limitations in the field of technology and today or some other day the most advanced and reliable technology has to come and replace all others. The fact that remains is the time which the technology would take to develop.

Imgur’s birthday bash : Imgur Pro to be free to all Imgur users.

Imgur's birthday bash : Imgur Pro to be free to all Imgur users.

Imgur Pro Is Now Free For Everyone

Imgur’s Pro tool which was otherwise under paid category would be free for all its users as it is celebrating its sixth successful birthday.

Imgur is a popular image sharing website which shares huge volumes of images with a count of about 1.5 million images per day to about 60 billion images in  a month.  Imgur generates its revenue by the ads and its Pro Tools. Standard Imgur subscriber has an upper limit of  uploading only 225 images. Imgur Pro is an updated version which would allow the subscribers to upload an unlimited account images at the cost of $24.00 per year.

Pro tool, not only uploads unlimited account images but also has the feature of  Advanced image analytics (that means it can derive correct meaning from digital images). Users who update from Imgur to Imgur Pro are not served ads.

However one of the earlier feature of Pro tool which has been removed is that the size of the image has been limited to 5 MB from the earlier 10 MB with an exception to the animated GIF which can have an upper limit of 200 MB. This move is made by Imgur so as to improve the quality of the images uploaded. There are other features of Pro Tools:  user can edit or delete any image at any time; users can interact with Imgur community through their votes, shares and comments.

Recently Imgur also released its new feature of Video to GIF feature, which can generate GIFs from any online videos.

The website “Imgur” was created just as a simple site to share images by Alan Schaaf  in the year 2009 mainly due to the drawbacks occuring in the similar sites. Imgur gained huge popularity due to social media like Reditt and Digg. Imgur Pro, paid account, was introduced on the first birthday anniversary of Imgur and now on the sixth anniversary Imgur has declared free usage of this tool to thank all their users who made Imgur one of the top websites for exploring, discussing and visual story telling.

“What began as a simple image uploading service has transformed into a community of the Internet’s most dynamic visual storytellers,” said Imgur in a blog post. “Imgur has become the best place to explore, share, and discuss the Internet’s images–and we couldn’t have done it without your support and loyalty. We’re looking forward to many more years of uniting the universe through images with you.”

You can sign up for Imgur pro now and avail all the features it offers.

Delete anti-Putin Tweets says autocratic Russia, Russian delete requests to Twitter tripled in last six months

Delete anti-Putin Tweets says autocratic Russia, Russian delete requests to Twitter tripled in last six months

Russian Government has increased its demand to delete tweets which are anti Putin, by almost three times in last six months

Twitter has started publishing a biannual “Twitter Transparency Report” since July 2012 and is celebrating the third anniversary of the publication. The report focuses on requests received from different governments regarding the account information, content removals and copyright violations. The report also provides an insight into whether any action has been taken by Twitter on these requests.

The latest report which has been published on Monday indicates that though Twitter has received similar request from countries across the world, the requests received from Turkey, Russia and Germany has been up by almost 40 percent against a comparison between the latest consecutive reports.

The transparency report shows a marked increase in the number of content removal  requests in comparison to the last report: Turkey 477 , Russia 91 and Germany 43. US too requested for 1622 removal requests and Twitter gave consent to  80 percent of the requests to be accepted and hence removed the content. However none of the requests from Turkey has been paid any attention to and as per news from a micro blogging site it seems that Turkey blocked the site for more than a week and Turkish citizens could not access the Twitter. Most of these tweets were by the critics against the corruption and government authorities.

The Government of Russian Federation however is the leader as far as the deletion requests are concerned.  Russia is in a deep internal turmoil over the Ukrainian crisis and anti Putin movements. To add to this there seems to be a severe trust deficit between the Prime Minister Dmitry Medvedev and President Vladimir Putin. The already discontented Russians are also irritated by economic crisis. Now, if these citizens are voicing their opinions about the Kremlin on Twitter it is being disapproved by the Russian government stating that these are the “revolutionary” comments and could call for protests.

Hence Kremlin has set new rules which would allow the government to restrict their citizens access to such “revolutionary” comments. As mentioned earlier, against a request of 91 content removals from Russian authorities twitter abided by only 13% as the rest of the requests were denied to “silence critics of Kremlin”.

In the times of democracy Russian Government is still behaving with hypocritic attitude by denying the claims made by Twitter in regards to remove the anti Putin content saying that this was done just to maintain law and order in the country. Critics have thoroughly condemned this act of  Putin, who is being supported by Kremlin.

Kickass Torrent website taken down after domain seizure

Kickass Torrent website taken down after domain seizure

Kickass Torrent domain seized by authorities, moves to its old .To domain again

The worlds most popular torrent websites Kickass Torrent today lost access to its .So domain name. As per the reports available, the Somalian Internet registration authorities have now banned Kickass from using its .so domain registry.

After the downfall of The Pirate bay in December, Kickass was ruling the roost of the torrent jungle with a millions of unique visitors per day. It seems that its popularity caused some angry nerves with the copyright groups and that sounded the death knell for its .so domain.

Kickass has been moving to different domain names to evade law enforcement and copyright advocacy groups for some time now.

In case you are visiting the kickass with so domain you will be shown as the website has been banned.

Moving back to its old .To domain

Though unlike Piratebay whose entire data center was knocked out after the police raid, Kickass had to only deal with domain seizure, therefore it quickly responded by moving to its old .To domain name.  The .To domain belong to Tonga, officially the Kingdom of Tonga, a Polynesian sovereign state.

Google to Shut down Gtalk Messenger on February 16th

Google to Shut down Gtalk on February 16th

Google: Gtalk will be no more operational after February 16th

Google’s Gtalk messenger platform is drawing its last few breaths and will go dead after 16th February. While the messenger has become very popular amongst millions of users its not that Google is putting end to its Messenger services but is upgrading it to Google Hangouts Messenger services for Windows users.

Gtalk was already made unavailable for download from Google after it announced last year that the end is nearer. after which users looking to download Gtalk were redirected to Google Hangouts download page.

Earlier this week Google once again notified Gtalk users to upgrade to Google hangout coz the app will go unoperational after Feb 16th.Google to Shut down Gtalk Messenger on February 16th

While Gtalk’s interface has become very familiar to many of its users not to forget mentioning that it loads better than Google Hangout on slow internet connections. Another problem is that it has also become lifeline for lower end older smartphone users because these phones dont support a all frills laden Google Hangout App. But Google seems to have other plans and security has become a major issue Google so it altogether dumping the Gtalk Messenger.

Google Hangout which only operates with its Chrome browser will also bind its users to use Google Chrome if they want to use the service, not to forget WhatsApp Recently getting on PC’s to give Google’s Messenger service a strong competition.

Major features that Google Hangout provides like Google Video Hangouts and Group Video Chats means that it is still a long way for others to give any sort of direct competition to it.

The notification from Google says the Gtalk app will go dead for the Windows user it does not say anything about users working on a different operating system than the Windows. Maybe Google plans to keep GChat live on other operating systems for the time being.

Does Facebook Cause Depression? Study reveals that bad Facebook usage can lead to depression

Does Facebook Cause Depression? Study reveals that bad Facebook usage can lead to depression

Study shows that ‘surveillance Facebooking’ can cause depression in people who compare themselves to other Facebook users

A study by University of Missouri shows that using Facebook causes envy and depression may soon follow. There have been many studies on the influences of Facebook on human minds but this one goes a step further and reveals that comparing ourselves to other Facebook users often leads to depression.

University of Missouri-Columbia study whose results are published here, states that Facebook can make us sadder,  but only if you’re using it to lurk from afar.  Lurking from afar means using Facebook to check on how your old acquaintance/friend/ex-girl friend/boy friend is doing, which actually engaging with them through ‘likes’ comments or sharing their posts.

The study by the two researchers Margaret Duffy and Edson Tandoc, has taken care to distinguish between the good kind and the bad kind of Facebook usage.

The researchers have found that users who use generally use Facebook to stay in touch with their near and dear ones, friends and acquaintances and post/share important events of their lives on their timelines do not suffer from symptoms of depression associated with use of the social networking site.

Regarding the bad side of Facebook usage, the researchers state that many users use Facebook for snooping/spying on their friends, old friends turned foes, ex-girl friends/boy friends and live king of “surveillance” life on Facebook.  The study says that these kind of users always compare the lives of their friends to their own and often end up having feelings of envy.

Those great photos from your high school girlfriend’s wedding reception? These kind of images make the “surveillance Facebookers” envious and envy is the start point for depression.

A similar kind of study by University of Michigan in 2013 linked Facebook use with decline in overall happiness, however an article on The Verge said that the study did not have a strict definition of Facebook use.  That is where this study differs and possible offers a plausible explanation for Facebook users suffering from depression.

As Tandoc puts it, “Users should be self-aware that positive self-presentation is an important motivation in using social media, so it is to be expected that many users would only post positive things about themselves. This self-awareness, hopefully, can lessen feelings of envy.”

Taking the study into account, it would be preferable to use Facebook to highlight the good things that happen in your life and sharing the same with your friends and near and dear ones instead of “surveillance Facebooking”

Google, Microsoft and Amazon will have to pay 30% of their additional ad revenue to Adblock Plus to get their ads unblocked

Google, Microsoft and Amazon will have to pay 30% of their additional ad revenue to Adbloc Plus to get their ads unblocked

Adblock Plus would be receiving  “30% of the additional ad revenues” from Google, Microsoft and Amazon just to unblock ads.

Adblock Plus blocks annoying ads on the web which includes blocking the “tracking” as well. Hence, with a count of monthly 50 million active users across the world its one of the most popular browser extensions.

Adblock Plus itself has no functionality, in the sense that it does not block anything until it is “told” what to do by its filter lists.  Adblock Plus is an open source project created by Wladimir Palant in 2006. EYEO, a German Company, was founded in 2011 by Wladimir Palant and Till Faida to make Adblock development sustainable.

Adblock Plus offers free service and claims to block the “annoying” banners, pop-ups and video ads. In order to block all the ads, Adblock users can get all the ads blocked by configuring the  software settings option to strictest options possible.

However, Ad blocking is an existential threat to internet services and tech firms who rely on advertising for the majority of their revenues. Adblock Plus also feels that not all the ads are bad and that that website owners need them to survive and places these type of sites under the criteria of “Acceptable Ads” as long as they are being transparent about the fact that they are advertising, and “do not disrupt or distort” page content.

The Acceptable Ads are under the “White List” criteria which the Adblock users can still block if they want to. The main hitch is that this white list is free for smaller sites and the bigger companies like Google, Microsoft, Amazon and Taboola are being asked to pay a fee which is equivalent to 30% of the additional revenues it would make from the advertisement if they were not blocked the Adblock Plus browser plugin.

As per the Eyeo spokesman Ben Williams, this “Acceptable Ads” initiative has been there since 2011 when the company was founded and it is as transparent as possible. He also added that in the White List 90% of the entities in accceptable ads are free for payers and non payers while the users still have the option to completely block all the ads.

It still remains a big question if the larger companies like Google, Microsoft, Amazon will pay this huge amount to Adblock Plus just to get their ads unblocked which eventually is upto the users as they still have the option to block these ads, anyways.

However going by the reports, Adblock Plus owners are certainly going to laugh all their way to the bank.

Danger ahead : Facebook’s new privacy policy lets it track you even when you are not on Facebook

Danger ahead : Facebook's new privacy policy lets it track you even when you are not on Facebook

Facebook is making users sign up for new privacy policy that allows it to track users everywhere on the Internet

This is really bad news for privacy lovers.  Facebook has just updated its privacy policy which allows Facebook to track you, the Facebook user activity even after you have left Facebook website to surf other pages. And more over you have already agreed to it without realizing it.

Facebooks new policy allows it to gather data about you, from across the internet. This is in addition to the normal data it generally gathers when you post something or add friends to your network.  The new privacy policy has such provisions that, Facebook now pass this information with its subsidiaries like WhatsApp and Instagram.

Readers may not know that Facebook had already announced the new privacy policy last November but it is being implemented from Friday.  You may be surprised as to why Facebook did not notify you, but it so happens that you are deemed to have agreed to the new policy once you log into Facebook.

Facebook management says that the new policy will help it tabulate data which can be used to serve precision adverts to the users and avoid serving unwanted information to them.

The saving grace is that you can opt out for some parts of the new policy by customising privacy settings. You can visit Facebook website settings page here and opt out of advertising that is shown on third party sites or is selected by comparing you with your friends.

If you want to opt out of Facebook tracking your use when you are not on Facebook, you can opt out by visiting individual pages listed in the privacy settings page for respective countries.

Danger ahead : Facebook's new privacy policy lets it track you even when you are not on Facebook

Facebook says that users can do so even from their mobile and tablet screens and the settings is will be treated as same across the board.

Google Earth Pro Is Now Available For Free

Google Earth Pro Is Now Available For Free

Google makes Google Earth Pro free to reach everyone’s PC.

Google has announced that it will no longer charge users to gain access to Google Earth Pro, the premium version of its geospatial desktop software that provides more than a billion people a virtual tour to our Earth.

Stafford Marquardt, the Google product manager for Google Earth Pro in a blog said that “ anyone who wants to use the software will have to request a free key to download and install the software on their computers“. Earlier the software cost a staggering $399 to use every year.

Since most people use the software mainly for their of virtual travel, the Pro version is targeted toward engineers, Google Earth Pro Is Now Available For Freearchitects, scientists, pilots, other professionals, and businesses who have used the advanced tools in Google Earth Pro for a variety of purposes, such as measuring 3D buildings, printing high-resolution images, and recording high-definition movies of one’s virtual travels.

“Over the last 10 years, businesses, scientists, and hobbyists from all over the world have been using Google Earth Pro for everything from planning hikes to placing solar panels on rooftops,” says Marquardt.

Both the software’s are equally beneficial but the two versions have some major differences. Firstly, Google Earth is limited to printing screen resolution images, while the Pro version allows users to print high-resolution images that can be used for presentations. It also allows importing of images that have more than the max texture size allowed by Google Earth.

Secondly, though both versions use the same imagery, but Google Earth Pro has additional tools to create animation videos and automatically locate geographic information system (GIS) images that can only be manually located in Google Earth.

Next, Google Earth Pro gives businesses and market researcher’s access to multiple layers of demographic data. For instance, for each state in the United States, Google Earth Pro provides demographic information related to age, gender, income, education, and other factors for a certain period.

Last but not the least, Google Earth Pro is now free, so there is virtually no barrier in using the software. The system required for the software is a PC running on Windows XP or higher or OS 10.6 or higher for Mac users. At least 500MB of storage and 512MB of RAM are needed.

Google Earth was acquired by Google as EarthViewer 3D, a project of the CIA-backed Keyhole, in 2004. The software maps the Earth by superimposing images obtained from satellite imagery, aerial photography, and GIS 3D globe.

New Features To Facebook Privacy

New Features To Facebook Privacy

New features adds to Facebook privacy policy- how would it help?

Last November, Facebook intended to change its privacy policy that was introduced on January 30, 2015 by sending messages to its users.

The changes can now be seen simply by logging into Facebook when you are accepting the new terms and conditions. Here’s all the information you need to know about what you’re signing up to – and how to manage it from today.

What will the latest changes provide?

The changes allow partnered advertisers to use Facebook users’ personal data to deliver targeted adverts to external websites and mobile devices.

New Features To Facebook Privacy

The updated policy seems not to be exactly new because adverts already follow users around the internet, especially inside Facebook – but now, Facebook data is being exported to the rest of the web which could make some users a tad uncomfortable.

People should remember that Facebook has access to all the personal information you provide when you sign up, who your friends are, information about purchases, what device you’re using, where you are, and what websites you’ve visited.

How Facebook uses my details?

The company states that it uses this information to improve and develop services, and “show and measure ads and services”.

Facebook states: “We want our advertising to be as relevant and interesting as the other information you find on our Services. With this in mind, we use all of the information we have about you to show you relevant ads.”

Further the company stresses: “We do not share information that personally identifies you.”

Facebook in, another post also states: “We help advertisers reach people with relevant ads without telling them who you are.” It adds that the latest update does not change this particular aspect of its policy to Facebook’s terms and conditions.

Essentially, websites that use Facebook’s advertising platform Atlas will be able to have a greater understanding of who you are, and deliver adverts based on what it knows of you.

How to stop the misuse of data?

The company doesn’t allow users to opt-out of their advertising services as long as they use Facebook

For those who don’t want to go to the extremes of installing an ad blocker, the only way to completely avoid these changes is to delete your account. This will also delete any associated information and data connected to your account.

fb_newsroom_spam_360

So to delete your account, just go to www.facebook.com/help/delete_account, and following the on-screen instructions.

However, if you want to know more about the details, the company provides a tool which allows users to download and view an archive of all the information that’s linked to your account.
