Mobile companies can predict where you will be in the future

Technological advances have transformed mobile phones into sophisticated gadgets capable to tell us when the next train arrives, to guide us when we lost and can even allow us to watch your favorite TV shows. Now, researchers have shown that this device can be used for something seemingly detached from SF: cell phone knows what we will do tomorrow! A team of computer scientists at the University of Birmingham managed to predict the future position of people just by looking at their mobile phones.

The margin of error predictions of scientists was only 20 meters, which has fueled concern that organizations advocating the protection of privacy. To predict where they will find the owners of mobile phones, scientists have devised an algorithm that predicts their future movements. The algorithm compares data analyzed data person close people, forming its social network.

Analyzing the places visited in the past and frequency of contact between friends, the algorithm can predict where the person will be in the future. For example, if two individuals who meet frequently visits a restaurant, it is very likely that the next time these two individuals while heading toward that area, they have targeted that restaurant.

The research was based on data generated by mobile phones to 200 people in Lausanne, Switzerland. Dr. Mirco Musolesi, study leader, said that the information extracted from the data generated by mobile phones is an interesting source of knowledge about human behavior. We proved that accurate predictions of the future location of a person can be enhanced when taken into account the moves it has made in the past, along with data generated by social group of individuals that make up that person.

Despite the fact that this system will benefit the marketing companies and police, organizations that advocate for privacy protection do not see with good eyes this technology. Researchers say the technology could be used by advertisers to create targeted advertisements, anticipating the places they intend to visit someone. Also, the technology could be used by companies to provide discounts personalized, real-time, depending on where it is estimated that it will find cell phone user. Also, scientists hope that this algorithm will be used in future for police to predict locations where crimes to be committed.

Efficiency of the system has been tested in several experiments Patwari and Wilson. They placed 28 so-called “nodes” of the network’s inside a hall, delineating an area of about 25 square meters, and then in a park with 34 nodes positioned along the perimeter of an area of 56 square meters ( devices were placed on plastic poles at the height of a man).

Since the presence of objects and people attenuate radio signals between nodes, Wilson and Patwari measured intensity radio waves from all nodes, so when areas were crossed by people moving, and when they were completely empty. They then developed a mathematical formula that allows a computer to convert these variations in intensity images of persons represented in the form of colored spots.

Snapchat an app that never had the money

Users preferred application worldwide now gained a few extra features that the part of the public makes it even more interesting. A young man killed two people and brought the … Code Yellow flood kept on rivers in 13 counties. Miss Danube … Snapchat is an instant messaging application that has been especially successful in the United States because he caught young.

What is she doing? Users sent pictures that theoretically self-destruct in 10 seconds for the user on the other side could see the image. Time is running when users hold down your finger on the image.
Now, Snapchat, which received a $ 3 billion offer from Facebook in 2013 and introduces video chat. The company’s official blog talks about network that the intention was always to be a cause for conversation.

Thus, users can now communicate among themselves through pictures that not only destroy themselves but also through the chat module. When you add someone to your friends list, we can give swipe to the right and enter into the conversation window. Also Snapchat announced and the ability to send video messages to other users.
Here is the video presentation of the newest options Snapchat between sexting and Facebook Snapchat caused an instant reaction from Facebook and Mark Zuckerberg says that Facebook Poke app has scheduled one who sent messages to self-destruct. Unfortunately for him, Poke was not successful, and people remained on Snapchat.
Why? Because sometimes it gives anonymity and because many users are going to Snapchat for sexting, ie sending dirty pictures with them by other users. According Snapchat, users send 150 million photos every day.

The problem with them is not always destroy themselves, but end up on the Internet. After a closed topic SnapchatSluts Reddit, users were not satisfied. Those who read the truth and use Snapchat, be careful who you share photos.
There are threads on Reddit LeakedSnapChat and NSFW_Snapchat (we give links to them). However, many do just that. They are bored and looking for strangers to talk to imaging. Subredditul can be accessed here. Why has successfully Snapchat?


Bill Curley, venture capitalistla Benchmark one of the first investors in Snapchat explains fame and the recent valuation at 800 million dollars (24 June with raising 60 million dollars to support) by two theories: there is much potential; there are no alternatives. In fact, this latter theory is interesting and Curley associates the success that Facebook has ceased to be a network of youth but was matured in a sober environment more sterile. Many young people see Facebook as LinkedIn.
And that means that they are concerned about the people who see what public – mother, teachers, neighbors, so will a place to communicate without worrying about privacy “, said Curley. He added that Snaphack is one of the companies with the largest increase in whose support was involved. Its explanations are available in full video below.
There are many studies that have shown that Facebook and Instagram make us unhappy, for a variety of reasons. Well, it seems that things are different in terms Snapchat, but not for the reasons you’d think.

Researchers at the University of Michigan conducted a study in which they demonstrated that Snapchat is an excellent platform for interaction satisfactory. Although for many it’s a social app created for sexting and to give young people a space for temporary distribution of pictures with sexual content, it is used more to communicate and interact with loved ones. A reached 100 million daily active users, which is a fairly relevant clue.
The study was conducted on 154 students of smartphone owners and was published in Information, Communication and Society. It is also one of the first studies that examines how social networks affect our mood. Wellbeing of the participants was assessed on the basis of their response to various messages sent per day. Were questions like “How well do you feel now?” Or “How pleasant or unpleasant was the last interaction?

Responses were analyzed and determined that users are happier and more positive when using Snapchat, compared to Facebook. On the other hand, Snapchat interactions are less useful in terms of support, compared to Twitter, text messages, emails, phone and face to face meetings, according to Yahoo! Tech.
Therefore, if Facebook can generate mental and depressive tendencies, Snapchat can do the opposite and it would not be bad to orient ourselves more to it.

Mobile History

Mobile History

The desire of people to communicate long distance was a dream since the beginning of history. And as mankind has progressed and evolved continuously media: rot smoke from the Indians at nineteenth century; the drum sounds of the African jungle, the letters sent by pigeons. And the biggest step towards modern communication system was made a century before there was the Internet: in 1876. That year, making separate studies and working in parallel, two inventors were announced – almost simultaneously – that have created a device that can transmit sound remotely. Their name: Elisha Gray and Alexander Graham Bell, the last of them proving to be faster in the presence of an innovative legal office thus obtaining patent licenses and invention. The Alexander Graham Bell made history as the inventor of the telephone, and Elisha Gray was – absolutely unjustly – completely forgotten.

By the 1990s, when they appeared mobiles and cell phones, the classic phone essentially has not changed since its invention. I mean, he remained the same device with a transmitter and a receiver, which can make long distance via electromagnetic waves propagated along the wires. Now it seems easy, but before Bell to think and put into practice, however, speak and hear you with another man, from thousands of kilometers seemed just a dream.

Alexander Graham Bell has focused on optimizing studies telegraph, a device that already exists and which was used for the remote transmission of signals with the help of electromagnetic waves. It was the famous Morse code, in which each digit and each letter was his assigned a unique combination of lines and dots. The disadvantages were high: both those who were sending, and receiving messages were those who needed to know Morse code and could not be sent and received only one message at the same time. In addition, it was impossible to hear the voice of him that wanted to communicate so you something. Bell started from a relatively simple observation: speech is limited to sounds. And sounds are actually some particle vibrations of elastic medium, which can be registered by ear. I mean, tambourines – those elastic membrane that transmit vibration, sound waves to the inner ear.

And then, Bell thought how to carry sound from the mouth of one who speaks in the listener’s ear, overseas. For this, a device equipped with a microphone and a receiver .More simple: make the speaker’s voice microphone diaphragm to vibrate, and this vibration in turn electrical oscillation. This oscillation starts on the line, like electricity, reaching almost instantly from the listening receiver and its diaphragm vibrate. And the sound of the diaphragm vibration receiver is absolutely identical to the one issued by the speaker. At first, Bell invented the phone have completely separate microphone and receiver, the first must be held with one hand in his mouth and the other – with the other hand, the right one ear. The first demonstration of the telephone conversation took place on March 10 1876 in the US city of Boston, the capital of Massachusetts. At one end of the line: Alexander Graham Bell. At the other end into a neighboring room: Thomas Watson, assistant inventor. When contact has been made, Bell spoke the famous words that have remained in history as the first sentences communicated in a phone conversation: “Mr. Watson, come here! I want to see you! ”

Alexander Graham Bell was born in 1847 in Edinburgh, capital of Scotland. He emigrated first in Ontario and then moved to the United States, in Boston before starting his career as a brilliant inventor. His entire life, Bell was very concerned with the problems of the deaf or hearing impaired, these people with special needs inventor striving to help with equipment and hearing aids. And this humanitarian interest helped Bell invent the microphone and then the phone. The news spread rapidly phone inventories across America, crossed the Atlantic and then stormed across Europe. Everyone would have wanted such a device! The wealthy have been obtained in a very short time, but only after a hundred years has become almost customary device in our homes and offices. In these more than a hundred years, Bell’s invention have been made a lot of improvements. The microphone and the receiver are now in the same song. The numbers are no longer formed by rotating a disk, but pressing the number buttons. Even landlines can have a station that is not connected by wire to the unit itself giving the user the ability to move through the house while talking.

Ordinary wires were replaced with optical fiber, more performance in terms of quality and speed of data transmission. And it all culminated in mobile telephony, where wires and cables disappeared completely, oscillations is directly transmitted through the air now – with the help of powerful antennas and reception or retransmission of funds is achieved through multiple relays. Mobile phones have a memory that can store hundreds of numbers, displays the caller’s number or name, and some of them have very special features: radio, modem or camera. But people always want more and better. And no longer content just to be heard in the distance. They wanted to see her while speaking. And the big manufacturers were quick to provide them with video-phone! A device of the last generation, equipped with speakers and monitor, with which the conversation can take place as and when those who speak it face to face. Have thought Alexander Graham Bell at all? It would be impossible as long as Jules Verne predicted space travel … But is what will happen next? How will evolve phone?
