Computing at the speed of light with Ultra-compact beamsplitter

Computing at the speed of light with 

Ultra-compact beamsplitter


University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines.
The Utah engineers have developed an ultracompact beamsplitter -- the smallest on record -- for dividing light waves into two separate channels of information. The device brings researchers closer to producing silicon photonic chips that compute and shuttle data with light instead of electrons. Electrical and computer engineering associate professor Rajesh Menon and colleagues describe their invention today in the journal Nature Photonics.
Silicon photonics could significantly increase the power and speed of machines such as supercomputers, data center servers and the specialized computers that direct autonomous cars and drones with collision detection. Eventually, the technology could reach home computers and mobile devices and improve applications from gaming to video streaming.
The overhead view of a new beamsplitter for silicon photonics chips that is the size of one-fiftieth the width of a human hair.


"Light is the fastest thing you can use to transmit information," says Menon. "But that information has to be converted to electrons when it comes into your laptop. In that conversion, you're slowing things down. The vision is to do everything in light." Photons of light carry information over the Internet through fiber-optic networks. But once a data stream reaches a home or office destination, the photons of light must be converted to electrons before a router or computer can handle the information. That bottleneck could be eliminated if the data stream remained as light within computer processors.
"With all light, computing can eventually be millions of times faster," says Menon.
To help do that, the U engineers created a much smaller form of a polarization beamsplitter (which looks somewhat like a barcode) on top of a silicon chip that can split guided incoming light into its two components. Before, such a beamsplitter was over 100 by 100 microns. Thanks to a new algorithm for designing the splitter, Menon's team has shrunk it to 2.4 by 2.4 microns, or one-fiftieth the width of a human hair and close to the limit of what is physically possible.
The beamsplitter would be just one of a multitude of passive devices placed on a silicon chip to direct light waves in different ways. By shrinking them down in size, researchers will be able to cram millions of these devices on a single chip.
Potential advantages go beyond processing speed. The Utah team's design would be cheap to produce because it uses existing fabrication techniques for creating silicon chips. And because photonic chips shuttle photons instead of electrons, mobile devices such as smartphones or tablets built with this technology would consume less power, have longer battery life and generate less heat than existing mobile devices.
The first supercomputers using silicon photonics -- already under development at companies such as Intel and IBM -- will use hybrid processors that remain partly electronic. Menon believes his beamsplitter could be used in those computers in about three years. Data centers that require faster connections between computers also could implement the technology soon, he says.

The Dark Side of the App Store

Article by Roy Pessis -CO founder / Wibki         on      November 13, 2014









Something great happened on July 10, 2008. The Apple App Store was born. Only six years down the road more than 60 billion apps were downloaded through the platform, making it one of the largest stores in history.

As Apple & Google are about to launch their app stores for the largest untapped screen in our homes, it’s worth pausing for a moment to address its dark side and understand the magnitude of its impact on our lives.

Is Apple the Supreme Court of our digital lives?

According to Nielsen, 89% of our time on media is spent via the use of apps. While apps occupy an enormous part of our digital lives, we remain indifferent to the fact that such an integral part of our online experience is entirely controlled by two companies: Apple and Google. Two companies decide what we do online, where we spend our time and who will be able to provide us with our sought-after content.

In their guidelines Apple states that the company “will reject Apps for any content or behavior that we believe is over the line. What line, you ask? Well, as a Supreme Court Justice once said, ‘I’ll know it when I see it’. And we think that you will also know it when you cross it.”

Where exactly is this line and which behaviors, according to Apple, are relegated to a place across it? Where will the line be in five years? As it currently seems, Apple has claimed a seat on the Supreme Court of our digital lives.

Both the Apple and the Google app stores control the flow of information. With every passing day, they tighten their grip over the content and delivery of our information. While this reality might seem harmless to many at the moment, in a few years time this could become a real threat over our freedom of speech and our freedom to create.

Is Apple the Supreme Court of our digital livesAnd it’s already happening: Consider the example of a company named Tawkon which created an app that tells you when your phone is emitting high radiation so users can stay safe. Apple rejected this app. When Tawkon founders asked Steve Jobs for an explanation, he simply replied “no interest.” Why would Apple block something that is good for us? I have a gut feeling that with the low cellular coverage in the US 4–5 years ago, Steve didn’t want his customers to stop using the phone because technically it is always emitting high radiation! This app could potentially harm the carriers that have lucrative partnerships with Apple.

Another interesting example is the blocking of bitcoin wallet apps, a policy which was only recently changed. Too late for bitcoin. The average user would much prefer using ApplePay. Blocking bitcoin wallets halts the spread of usage while Apple is building their ApplePay strategy, allowing them an unfair advantage. The ecosystem survives and we are trapped.

Again and again, Apple rejects apps not on the basis of malicious activity, but on the basis of pure capital gain.

We are willingly giving Apple and Google full control over our digital lives
The app stores are fun, endless, constantly updating and truly quite amazing. I love discovering new apps every Thursday when the Featured list is updated. The best part about it is the ease with which the app store works in enabling users to discover, purchase and install new apps. Just place your thumb on the screen and it’s already on its way.

Apple and Google have focused their strategies on creating a population of habitual app-store users. After all, no matter what you need, “there’s an app for that!” Getting us hooked on this experience is exactly what they want because with each purchase we make from their store, they extract an astounding 30% commission.

A 30 percent commission is an outrage (speak now or forever hold your peace)
At the beginning of this post, I mentioned that 60 billion apps have been downloaded until today (and that’s just on iOS). While a high percentage of them are free apps, this is nevertheless a huge market from which to reap 30% commission.

Of course, Apple and Google only aim to enlarge this market and their share within it. In fact, they would much rather prefer we stop using the Web and only use apps. They get their 30%, further tighten their grip over our digital freedom, and in return we get ease. What many don’t realize is that this ease we are so used to can also be available in an open format that is not so heavily controlled by our digital overlords.

The TV is Changing







We must keep our eyes open for Apple’s long term strategy behind the app store.
Some day in the near future, Apple will hold an event announcing the opening of AppleTV to developers. Probably they will bring some developers on stage to talk about how amazing it is to port their successful iPhone games and apps on to the big screen. They will praise Apple and try to convince fellow developers that this is the next big thing that they all should be working on. And it probably is—when push comes to shove, we are talking about the last un-stored screen. While it is a huge opportunity for developers, we must keep our eyes open for Apple’s long term strategy behind the app store.

Apple is poised to control the TV. I hope that the new AppleTV will have a fully functioning browser so we can still enjoy the Web freely and to the fullest. Unfortunately, I am not so optimistic. After all, it did take Apple four years to make a decent browser for the iPhone. You can probably guess why.

The Web should be free and accessible for everyone.
Unlike the app-stores of our digital overlords, the Web does not filter or restrain our content. No single entity controls what goes online and what does not. Anyone can take a computer, plug it to the wall, and define it as a server. Without a court order, no one can take that away from you.

It goes without saying that Apple and Google should be transparent regarding their policy for refusing apps. While it is well within these companies’ right to seek maximum profit without the need to ascribe to any higher moral ground, it is important to remember that we as consumers also have the right and power to choose. We should continue fighting for an open app store and not accept their app regime as ironclad.

In March, James Robinson wrote “2013 was the first year that Americans spent more time online on mobile devices than on computers, and as mobile devices become our primary point of interaction, the online experience will gradually become synonymous with being inside an app. It’s just like the Internet, but reimagined as a branded experience and with new, less democratic power structures, like Apple, Google and Facebook ruling the information roost like the Chevron, Exxon and BP of the world wide web.”Roy Pessis - Co Founder & CTO of Wibki & All My Faves


An open app store based on the Web could be the cure for that.

Is WhatsApp Worth $19bn ?


Is WhatsApp Worth $19bn? It Is To Facebook, And Here’s Why

The WhatsApp acquisition price sounds high, sky high, crazy high. But it’s not if you put yourself in Zuckerberg’s shoes and think about it in these terms:
Facebook bought a network that was a real threat to its existence, that is growing much faster than itself (growth drives valuations) and has almost half as many members already, for only 10% of its value.
And it prevented it from going to Google.
So from this perspective it is reasonable to pay that price. And if you call WhatsApp a better SMS system, hence an attack on the telco industry, on size alone, it is as big as half of all the texting that goes on in the world.
SMS, as Facebook said in its investor conference after the acquisition, is a $100 billion industry. Where are Facebook/WhatsApp headed? In my view towards doing with telephone minutes what WhatsApp already did with SMS.
WhatsApp killed the I-bill-you-by-text-message telco model. I would not be surprised if WhatsApp next move is to kill the I-bill-you-by-the-minute model. It is not reasonable that Facebook, which wants to connect everyone on the planet, still does not have a platform for people to have actual conversations a la Viber or Skype. I can’t imagine that things will stay this way. And owning the world’s texting and the world’s conversations may very well be worth $19bn.
What we have learned about Facebook is that Zuckerberg will pay whatever he has to pay to stop a rising competitor from eating his lunch. First Instagram, now WhatsApp.
Moreover that he can live and let live, acquire and keep the acquired company in shape. Instagram is still pretty much the same product it was when it was acquired. WhatsApp is likely to evolve but on its own.

If they disappear…….?

So many don’t want to live in a world without them; so many will cry ;so many will be disturbed; so many will suicide    owww can’t imagine it if the social networking sites  disappearing one day from the digital world
                                           Got A BACKUP PLAN…?
With 900 million people around the world logging into Facebook on a regular basis, you might be inclined to think the social networking site will be around forever.
However, Eric Jackson, the founder of investment firm Ironfire Capital, begs to differ. Speaking on CNBC’s business show Squawk on the Street on Monday, Jackson said he believes Facebook will have “disappeared” by 2020.
“In five to eight years they are going to disappear in the way that Yahoo has disappeared. Yahoo is still making money, it’s still profitable, still has 13,000 employees working for it, but it’s 10 percent of the value that it was at the height of 2000. For all intents and purposes, it’s disappeared,” Jackson said on the show.

return of investment


Return Of Investment (ROI) in Social media marketing

The key to the success of any website or online campaign is that it is designed
with clearly defined objectives in mind. These will be used to measure the
success of the website or campaign, and are crucial to maintaining focus within
online activities you have to use various kind of analytical tools to check your marketing performance .like google analytics and various free and paid services are available now  
In order to track the performance of your efforts, you need to have an analytics program in place. Marketing analytics tie to your CRM solution and reveal astonishing data not only on traffic and leads, but also on new customers acquired from various channels and campaigns.
To get  a good report you need to monitor several key factors.
Traffic-
Overall, how many people are coming to your website? Look
into what channel drove the most and least visits.
Leads-
How much of this traffic are you converting into leads and potential customers? This number should be constantly growing to ensure a steady flow of revenue.
Customers-
You should always be mapping your campaigns and channels
to customer acquisition. How many sales did you close this
month?
Traffic, Leads and Sales by Keywords
you need to know which keywords are drawing in the most visitors to your
site. This is actually data that Google Analytics can provide you with easily. However, you should
go deeper than that. Which keywords brought in the most sales?
Customer Acquisition Cost
How much are you investing to draw in each new customer? If you rely primarily on outbound Marketing methods, like trade shows and direct mail, your cost per customer is probably pretty high.
Effectiveness by Chanel
What promotional channels or referring sources are sending you the most traffic?

Tracking, analysing and optimising is vital to the success of any marketing
efforts, and even more so to digital marketing efforts. digital marketing allows
for easy and fast tracking, and the ability to optimise frequently.

ROI = (return – investment) / investment %.
This means that if you increase your return while keeping your investment the same, then you increase your ROI. This is good. If you decrease your return while keeping your investment the same, then the ROI goes down. That’s bad. A high ROI is better than a low ROI.
 Because the ROI formula uses only two inputs – the return and the investment – the ROI formula is an easy way to measure and compare marketing campaigns.
