Facts about Facebook Graph Search

Facebook has launched Graph Search. It is  new search tool that uses social data to provide you with the best possible answers to your queries. I have tried to list of  things you need to know about Facebook Graph Search.

  
 

1. What Facebook search can do?

Facebook Graph Search is a new social search tool aimed at making it easier for users to find people, photos, places, interests. You can look for people who live in the same city as you or like your favorite cuisine. Similarly, you can ask for reviews of a movie or a restaurant that you are thinking of checking out and lots more with this feature.

All you need to do is to type the specific question in the big search bar on top of a Facebook page. You can even improve queries with 'Refine This Search' box, placed on the side of the search bar.

2. What to search?
With Facebook Graph Search, you can ask specific questions about your friends, such as 'my friends who like The Beatles' or places your friends 'like'. Not only this, you can be even more specific while asking questions, for example 'my friends in New Delhi, who like trekking'.
Graph Search will dig out the best photos of your friends, based on the most number of likes and comments they get.
3. Availability of Facebook graph search
Currently, Facebook Graph Search is in early stage of beta testing development  It will initially be available for only a few thousand users in the US. However, you can sign up for Graph Search beta testing at www.facebook.com/graphsearch even if it is not available in your region and join the waiting list
4. Device on which this search is available

5. This is not Web search

6.What are my searchable  Facebook data?
 Only data that is marked Public is searchable

 Facebook CEO Mark Zuckerburg stressed that only the data you share with the world will be included while computing Graph Search results. Therefore, if you have made a certain photograph available to friends of your friends, then they may find it in the result upon making a specific query, even though you are not directly connected. Same goes for pages you have liked, places you were tagged at and movies you saw, events you went to etc.
However, Facebook will not take into account status updates while computing Graph Search results.

7. No change in Privacy setting for user
 Graph Search does not change your current privacy settings in any manner. People can only search for content that has been shared by you.

Flightradar24 shows live air traffic from around the world. The primary technology they use to receive flight information is called automatic dependent surveillance-broadcast (ADS-B). 
Flightradar24 has a network of about 500 ADS-B receivers across the world that receives plane and flight information from aircraft  and sends this information to a flightradar24 server, and then displays this information on a map on Flightradar24. Only aircraft with an ADS-B transponder, within the coverage area of the 500 receivers are visible.
Flightradar24 only have coverage in areas where someone has installed an ADS-B receiver and feeds his/her data into Flightradar24. If there are no connected ABS-B receivers in an area, then there is no coverage in that area.

In addition to ADS-B data, we also display data from the Federal Aviation Administration (FAA). This data provides full coverage of the airspace above the United States and Canada.
Flightradar24 covers about 90% of Europe. There is also some coverage in USA, Canada, Australia, Brazil, Middle East, Japan ,India and rest of world

Flightradar24 relies on volunteers around the world for the majority of our coverage. Find out how you can contribute.
Basic data flow in Flightradar24

Aircraft gets its location from a GPS navigation source (satellite)=>ADS-B unit on aircraft transmits signal containing about the location (and much and more)=>ADS-B signal is picked up by a receiver connected to Flightradar24 =>Receiver feeds data to Flightradar24

Today, roughly 60% of all passenger aircraft (70% in Europe, 30% in the US) are equipped with an ADS-B transponder. This percentage is steadily increasing as ADS-B is set to replace radar as the primary surveillance method for controlling aircraft.
