connecting world through Facebook
Data can be more interested if we visualize like a picture than in the words by using lens from different angles to present the data. If the data is the social graph of apporximatly of 500 million people then we need to use more number of lenses to veiw it, and the one same like that is the locality of friendship which are living in different geographical and political borders.” I wanted a visualization that would show which cities had a lot of friendships between then” ( Paul Butler 2010) .
He started by taking few member of people about ten million pairs of friends from Apache Hive in to data warehouse and by utilising the each user’s current city, he started merging that data with it and comined the friends, and then merging that data with the longitude and latitude of each of those cities.
He started diagnosed as a R , which is a open-source statistics environment.After he marked some of the points on coordinates of latitude and longitude, it looks like a world and then he plotted the lines in between the points which appears as the outline of the continents because of the less data.
To know the clear picture of that ,he used to weights for each pair of cities as a function of a metric space that is linear and finite-dimensional between them and the number of friends between them and mared the lines in the between weights ,to make the cities having huge number of friends between them were plotted on the top of the others and used black to blue to white colors depending on its weight.
By doing all the work on it , the picture become a wonderful and detailed map of the world with few parts of the continents in visible and international borders as well, which is filled with friends, family members or college friends living apart from one other and having different people making friendship from different areas and showing human realtionship. However, huge group of the world are missing because of the less usage of facebook such as China and central Africa.

Points of Control
John Battelle and Tim O’Reilly initiate the Web 2.0 summit to show the future
strategy of web technologies, both of them have a an excellent thoughts and views
about the web or business space. Same as them now the new business innovators
who are from Google, Twitter,Facebook, Baidu, and many other properties in the
global web space are shared about the ideas of future and also this year theme
was about the Points of Control.
Five Key Strategies From The Web 2.0 Summit
- Go Social/Mobile or Become Irrelevant
- Build A Diverse Empire, Measure, Refine
- Learn Everything You Can About Social Behavior
- Share Value of Collective Intelligence
- Focus on User Experience
You can learn more about this map here
Now we can know about Points of Control through experts talk.

Over-budget telescope threatens other projects
Hubble’s heir, the James Webb Space Telescope, isn’t even off the ground, but its soaring costs are casting ominous shadows over other NASA projects.JWST will have a foldable 6.5-metre mirror to peer back to the very first galaxies. But the ambitious mission is both behind schedule and over budget.Now, an independent panel estimates the telescope will cost $1.5 billion more than its already huge $5 billion price tag and will launch at least a year after its planned 2014 lift-off.To launch in 2015, the panel reckons the project will need an extra $500 million over the next two years, and NASA admits Congress is unlikely to cough up extra cash.
Instead, funding might be siphoned from proposed projects such as the Wide-Field Infrared Survey Telescope, a $1.6 billion mission to study dark energy and exoplanets thatrecently topped astronomers’ wish list for space missions in the next decade.Debra Elmegreen, president of theAmerican Astronomical Society, says the good news is that NASA has decided to pull JWST out of the agency’s astrophysics division, where it now eats up about 40 per cent of the budget.
Instead, JWST will be its own division, allowing it to draw funding from multiple sources within the agency. “There simply isn’t enough money [in astrophysics], and if they try to fill it from there, it will kill astronomy,” she says.
To detect Firesheep we have Blacksheep
Firesheep, the extension that lets you take over other people’s Facebook profiles? Well, an antidote’s been created by a cloud security company called Zscaler. It’s called BlackSheep.
BlackSheep, like Firesheep, takes the form of a Firefox extension. It sets up a honeytrap, where fake information is sent to random supported sites in the same format that Firesheep uses. The extension then listens for Firesheep users making their own connections using the fake cookie values, and identifies their IP address so that you can track them down or cut off their web access.
Once a user is detected, you’ll get a small banner below your Firefox tab bar that warns you that someone is operating FireSheep on the network and displays their IP. Fake traffic is generated every five minutes, but the interval is configurable if you’re particularly worried about people accessing your data. It has the same system requirements that firefox does, because it operates in a very similar way — listening to data being sent openly over a network and grabbing identity information from that.
There’s a video below showing how it works.

cancer tumours can detect from the jellyfish
The Jellyfish which are glowing under the water are going to use to detect the cancer tumours.These jellyfish are being used to light-up cancerous tumours instead of X-rays.Scientist injecting the flourescent proteins from the jellyfish into human cancer cells by using special cameras.
A team from the Yorshire Cancer Research Laboratory at York University has developed the procedure and its leader, Professor Norman Maitland trying to use this method and improve the scientific technology and to detect the cancer tumours and to cure the cancer as easy as possible.
Mobile communication will becoming body-to-body network communication
Engineers from Queen’s Institute of Electronics belfast are trying to turn the world into new direction through their research work on developing of body-to-body network technology same as the mesh network“batphones” developed by researchers in Australia and the new device-to-device wireless technology developed by the Wi-Fi Alliance.
The body-to-body network as so many great social benefits, healthcare improvements,the number of base stations required for the services of mobile phone users will reduce,improves the performance of mobile technology.
The Queen’s university Belfast team starts doing research by collaborating with the experts to develop the body centric communications.
