Facebook acquires WhatsApp for $19 billion

Facebook whats app

Facebook will acquire messaging company WhatsApp for $19 billion , The purchase includes $12 billion in Facebook shares and $4 billion cash.

It calls for an additional $3 billion in restricted stock units to be granted to WhatsApp founders and employees that will vest over four years. This is the largest acquisition that the company had ever made, it brought instagram for $1 billion in 2012, Not only that it , this acquisition  is larger than any of that Google, Microsoft and apple had done.
WhatsApp is a cross-platform mobile app that allows users to exchange messages without having to pay phone charges.

In a blog post Facebook explained its decision to acquire WhatsApp, there said "The acquisition supports Facebook and WhatsApp’s shared mission to bring more connectivity and utility to the world by delivering core internet services efficiently and affordability.",
Zuckerberg said at a investor call   "WhatsApp is on a path to connect one billion people. The services that reach that milestone are all incredibly valuable, I've known  Jan(koum) (WhatsApp founder) for a long time, and I'm excited to partner with him and his team to make the world more open and connected.

In a blogMr Koum statement appeared as “WhatsApp will remain autonomous and operate independently. You can continue to enjoy the service for a nominal fee. You can continue to use WhatsApp no matter where in the world you are, or what smartphone you’re using. And you can still count on absolutely no ads interrupting your communication.”  Almost five years ago we started WhatsApp with a simple mission: building a cool product used globally by everybody. Nothing else mattered to us.

"Today we are announcing a partnership with Facebook that will allow us to continue on that simple mission. Doing this will give WhatsApp the flexibility to grow and expand, while giving me, Brian, and the rest of our team more time to focus on building a communications service that’s as fast, affordable and personal as possible. "

How GPS Works?


global positioning system

The Global Positioning System (GPS) allows a person to locate his or her position anywhere on the planet, at any time, using a small handheld receiver. Originally developed as a military project, GPS has now reached every corner of civilian life. Today it is not only an essential tool in ships and aircraft, but it is also becoming, due to its multiple applications, a common feature in vehicles as well as in athletic and scientific equipment.

Since GPS is a dynamic system, it also provides real-time data about the movement, direction , and speed of the user, allowing for large number of user.

The civilian user determines his or her position using three- dimentional geographic coordinates, with a margin of error between 7  and 50 feet (2-15m) depending on the quality of the receiver and the satellite it detects at any given moment.

Extrapolation of the coordinates using geographic charts of cities, roads, rivers, oceans, and airspace can produce a dynamic map of user's position and movement.

the user can know the speed at which he/ she is traveling, the distance travelled. and the time elapsed. In addition, other information is provided, such as average speed.

4. Trips
Trips can be programmed using predetermined points (waypoints). During the trip, the GPS receiver provide information about the remaining distance to each waypoint, the correct direction, and the estimated time of arrival.

Although it was originally developed as a navigational system. GPS is used today in a variety of fields. The free use of this tool for work, business, recreation and sports activities is changing the way we move and act.

Way of Working
The Navstar GPS satellite are the heart of the system. The satellite emit signals that are intercepts by the GPS receiver to determine its location on a map. The System has a constellation of 24 main satellites that orbit the earth at an altitude of 12,550 miles(20,200Km) collectively covering the entire surface of the planet. They circle the earth every 12 hours.

1.The receiver detects one of the satellite and calculates its distance. This distance is the radius of a sphere whose center is the satellite and on whose surface the user can be located, although at a point yet to be determined.

2.When a second satellite is detected and the distance calculated, a second sphere is formed that intersects with the first sphere along a circle. The user can be located anywhere along the perimeter of the circle.

3. A third satellite forms a third sphere that intersects the circle at two points. one as an invalid location (for example, a position above the surface of the earth). The other points is the correct location. The more satellite used, the lower the margin of error.

Calculating The Distances

Once the GPS satellites are detected by the GPS receiver, the receiver's challenge is to precisely calculate its distance and position in relation to those satellites

1.The receiver has in its memory the satellites' ephemerides (from the Greek word ephemeros, meaning “daily”)—that is, their position in the sky by the hour and day

2.Upon detection of a satellite, it receives a highly complex signal of on-off pulses called a pseudo-random code.

3.The receiver recognizes the code and the exact time of each repetition (the signal includes corrections to the receiver's clock). By means of comparison, the receiver determines the lag in the satellite's signal, and since it knows the signal's speed, it can determine the distance

The TERMES Robots Are Inspired By TERMITES

The TERMES robots can build themselves staircases to reach the next construction points, and they know how to add bricks that advance construction without blocking important paths.

A team of computer scientists and engineers at the Harvard School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering at Harvard University has created an autonomous robotic construction crew. Inspired by the termite. Insects don’t have the capacity to reason, and yet some are capable of building complex structures without ant central leader/ organisation.

Harvard graduate student Kirstin Petersen and staff scientist Justin Werfel admire a termite mound in Namibia.

"On the plains of Namibia, millions of tiny termites are building a mound of soil—an 8-foot-tall "lung" for their underground nest. During a year of construction, many termites will live and die, wind and rain will erode the structure, and yet the colony's life-sustaining project will continue." said a team member, The system needs no supervisor, no eye in the sky, and no communication: just simple robots—any number of robots—that cooperate by modifying their environment.

 "The key inspiration we took from termites is the idea that you can do something really complicated as a group, without a supervisor, and secondly that you can do it without everybody discussing explicitly what's going on, but just by modifying the environment," says principal investigator Radhika Nagpal said in a release.
“We co-designed robots and bricks in an effort to make the system as minimalist and reliable as possible,” paper co-author Kirstin Petersen said in the release. “Not only does this help to make the system more robust, it also greatly simplifies the amount of computing required of the onboard processor. The idea is not just to reduce the number of small-scale errors, but more so to detect and correct them before they propagate into errors that can be fatal to the entire system.”

These robots can perform all the necessary tasks—carrying blocks, climbing the structure, attaching the blocks, and so on—with only four simple types of sensors and three actuators.

Nokia Normandy Priced At Vietnamese Retailer


A press image of this purported smartphone was leaked in late November and published by @evleaks on Twitter

  No, Nokia haven't launched the expected normandy phone 
yet, but a Vietnamese online Retaile site Showing Nokia X A110 at a cost of $110, when converted from local currency.

At the same retailer the Nokia Lumia 525 costs 3.39 million VND, or around $160, when prices of Nokia Asha 503 are checked in Amazon U.k site, it is found almost same as $110.  The specs for the handsets are pretty similar, except for 512 MB less RAM and 4 GB less storage.

As in, dec 14 post, i discussed that Microsoft could benefit if Nokia Manufactures Android Based phones the Reasons behind this, is that the Android OS is free (Android Open Source Project or AOSP) Any device using this platform doesn't have to pay for it, thus making the device a little less costly. and Also manufacturer can fully control the user experience adding additional features into it, which a android powered smart phone lacks.

Think of Nokia Care, CityLens, Bing, Skype, Office, and SkyDrive this List may grew longer.  The handset is expected to launch in March, which is of course after Mobile World Congress, so we may get to see it there after all.

Look Robocop Is Coming

robocob testing
Student Jamie Danow, right, 28, looks on as Irvin Cardenas, second from right, 22, controls a TeleBot, which combines telepresence and robotics, with sensors placed around his body, during a demonstration at Florida International University.

Research is being going on to bring Robocop in real life, by Undergraduate students  from Florida international  university's Discovery Lab. Though the robot is in initial phase of its development.
Though the implications are enormous and could  help disabled police officers and military personal by serving as patrol police.

Built from scratch, Telebot functions via an Oculus Rift headset, a motion-tracking vest, arm bands and gloves — all worn by a remote person. The headset gives that person a live-feed of the robot’s field of vision while the vest relays movements to the robot. The motion-sensing gloves control robot’s hands.

robocop testing 2The Telebot was made possible by Jeremy Robins, a lieutenant in the U.S. Navy, who donated $20,000 towards the project to help his disabled veteran friends get back into the work force.
