Random Surfer

In my last post i mentioned a word Random Surfer. It was purely under my subconscious mind. When I just started reading that post again, my concentration suddenly turned towards this word. Who is this Random Surfer?? It was a very familiar word to me and decided to write about it. Its gonna be a bit technical kindly excuse. Last semester in my semantic web course I had to implement a paper titled "Ranking Knowledge in Semantic Web". It was very interesting paper where i came to know about the concept behind Search Engines and the way they rank the result pages. The famous page rank algorithm used in search engines like Google is based on the Random Surfer Model. The code of the surfer is very simple. Whenever a surfer views a page he has certain probability to click a link in that page or to jump to a some other page. This is usually the famous 90-10 rule where the probability to click a link on the page is 0.9 and to jump to a random page is 0.1. The page rank will be a summation of all this probability. To sum up if a page has lot of inbound links it has the greater probability to be visited and hence has a higher page rank. In the real web this is more complex because the actual page rank will also depend upon the page rank of the page from which it has a inbound link. This will seem too complex and it is complex reallly. Imagine the graph or matrix the search engines has to maintain to establish the relationship between these pages(Thats awesome Isn't it?). They achieve this type of computing power very easily using grid computing.
Now if you are really curious and want to know the number of inbound links you have just click here and enter your blog or website and findout. To get more information on Random Surfer Model and Page Rank Calculation Click here

Random Surfing

I am a Random Surfer on the net. I search on some irrelevant keywords and end up finding something else. Doing so i suddenly came across two blogs which was quite interesting to me. These two bloggers are actually singers. The first one was by Chinamayee, the singer, CEO, Blogger,Translator,TV anchor and RJ. Her Blog had lot of information about music and her careers. The next blog was from Blaaze, the rapper. It was nice reading his blog where he gives lot of information about his early life. His latest song is dedicated to the victims of Mumbai Terror Attacks. He has done this along with Prince Ali & Raqueeb Alam. The message he tells through the songs is really wonderful. I salute this person for he has used his talents in the right direction. Not many do that. To download the song Click here. Hear it and pass the message to your friends.

A Tribute to ARR

Right from the days i began to listen to music, I admired AR Rahman so much. I could feel the freshness in each and every song that he has composed. He had been one of my inspiration right from my early college not for the musical talent he has but for the person he is. His early life was a tragedy, poor boy had to play keyboard for his living. But today he is on each and every part of the media around the world. He is actually the true slumdog millionaire. I am happy and glad that I gave a speech titled "From Napier Bridge to London Bridge" throwing light on the biography of this maestro in my English Skills Class in the first year of my college. I admire him for his love for the motherland and his humility "Ella pughazalum Iraivanukay". When i first heard slumdog millionaire it didnt sound that great comparing his earlier projects. Slumdog millionaire earned him 2 Oscars. But according to me 2 oscars for slumdog millionaire means he should have got more than 50 oscars for his earlier works. Rite from Roja, Lagaan, Vande Mataram, Swadesh, Range De Basanthi, Taal, Yuva and Jodha Akbar should have been given oscars. I congratulate him for the winning 2 oscars and wish him to spread love towards mankind through his music

My Recent Chennai Trip

Last weekend i had gone to Chennai to attend one of my senior Venkat's engagement with seniors, my roomie and Classmates. It was after a long time i got a chance to visit some places in Chennai. The whole two days was filled with fun and excitement. It reminded me of my old days in Chennai. The engagement was on Sunday. So, I decided to do a little bit of shopping on Saturday with my classmates. I reached Adayar where my classmates Suba and Deepthi stayed. Then, we did some shopping in Adayar. We planned to have lunch in Sanjeevani - a Ayurvedic Kerala Style Restaurant, but unfortunately we ended up being late and also due to the crowd we ended up in a ordinary restaurant nearby. We were fortunate to meet one of our senior Sethu. It was nice talking with him after a long time. Then, along with Pavi and Suba proceeded to T Nagar for a second round of shopping. The place was the same old with heavily crowded streets. We went to Saravana Stores and Pothys. We bought couple of clothes for each of us and returned home. The next day we had to get up early by 4 am since the engagement was at a place called Perambakkam 40 km away from the City. It was a very pleasant experience. Most of the time we spent pulling each other legs with special target as me. Then we played UNO with much fun. The journey was awesome with greenaries on both sides of the roads. Once we reached there we had a wonderful village style hospitality. We were given a great hospitality there only the red carpet was missing. The engagement went on well. Thanks to our photography experts Satyendra, Ragu and Satish who had been clicking all the time. Then myself, suba and Pavi went back to Adayar. There we joined Deepthi and left to Besant Nagar Beach. It was really exciting experience there. The beach sand, lot of ppl, kites flying, ballon shooting, beach volley ball etc every scene was filled with beauty. We played in the Sea waves for sometime. The large golden sun on one side and the rising moon on the other side was a awsome scene to watch. We ate fried fish at the beach which tasted heaven. Each and every moment in the beach was amazing. Then we had tasty idly, dosa and paniyaram at murugun idly shop. Since Pavi was new to the city we decided her to take her in the metro train. We also met our old friend Paul at the railway station. It was nice meeting him after a long time. Then we enjoyed the short ride in the metro train to park station. We were tight on schedule and reached the Central Railway Station on time. All together we had a small Chennai Class get together but missed Raji. We were left with nostalgic feelings of college life and missed our beloved friends. Meeting friends and sharing things after a long time is really a pleasant experience and these fun and sentiment filled moments will be cherished forever.

Dubai - A Magical City

Most of them would have heard lot about the city Dubai. The word is so common that we come across it more frequently. People can never forget the Vadivelu Jokes such as Hello!! Dubaaai ah? and Vivekananda theyru. Recently I happened to visit this place. It was about 14 long years I had been to this place. Though I was too young to remember, It was obviously clear that the growth the city has undergone is unbelievable.
Dubai as a city has very scarce resource of oil. The Ruler of the city has realized this and started transforming the city into a wonderful tourist destination. Unlike other Arab countries Dubai does not have a very strict Muslim culture. The expats contribute about 80% of the population and are from different parts of the world. Rich people around the globe such as tennis players, football players, actor, actress and business people own a apartments with a private beach. They spend their holidays there. The city has a really become a center for real estates.
My days in Dubai was really memorable so i would like to share the must see places in Dubai. Touring Dubai is relatively cheaper. The following are some of the best places to see.
The Beaches and Creekside
Dubai is known for its beaches. Despite having a minimum strip of beaches they have made artificial Islands and cut lands for beaches. The Jumeirah beach is a public beach with a view of the world famous 7 star Hotel Burj Al Arab. Opposite to that there are parks which are good place for relaxation.
Dubai is divided into two sides by a artificial sea water channel as Bur Dubai and Dubai. On the bank of this channel is the creekside where there are lot of cruises. You can sail in the cruise along withdinner, dance and rocking arabian music. There are lot of boat service to cross the channel which poor people use even today.Jumeirah Beach


Shopping Malls.
There are lot of huge shopping malls in dubai. Mostly suited for window shopping. The most famous is the Mall of the Emirates. It has the largest artificial skiing arena which has a height of a three storey building. The next is the Dubai Mall. It is the largest mall in the world. The world tallest building, Burj Dubai is a part of this mall. Once finished people can freely visit to the 144th floor and be at the tallest manmade structure in the world. There is a very big aquarium in the center of the mall. There are lot of rare fishes ranging from big size sharks and small fishes. You can see Shark Feeding by divers twice a day.
Never miss Ibanbatuta Mall. I liked it very much for its architecture. It features different cultures of the world lije chinese, egyptians etc. Actually Iban batuta is a traveller and this mall features the places he visited. There are large boats and ancient market place like structures inside. The other malls in Dubai include Outlet Mall and Dragon Mart. You get only chinese products in Dragon mart.

Artificial Islands
Palm Jumierah is the largest man made Island in the shape of a Palm tree. The Island is fully self contained with schools, apartments, hotels and recreation center. There is a underwater tunnel to connect to the cresent of the Island. Once you reach there. You can see the magnificent Atlantis Hotel. Lulu Island is another man made Island situated in Abu Dhabi. It has rafting on speed boats, desert scooters and fresh water pools. Never miss these Islands if u go to Dubai.
Shiekh Zayed Road
All the skyscrapers in Dubai is strictly concentrated in and around the Shiekh Zayed Road so never miss this road. I fortunately was able to be at level 79 of a building and snapped few pics of this road. Adjacent to this building was the Burj Dubai, The tallest building in the world. When you come along the road you can see lot of car showrooms all ranging from Ferari, Mercedes,Volskwagon,Bentley,GT, BMW to Toyoto, Hyundai and Nissan.
Desert Safari.
You must never miss desert safari if you go to Dubai. Its a event which starts in the evening and ends with the dinner. They take you through a muddy desert which would be very thrilling. They stop for the view of the sunset in the evening and then halt at a camp at the center of the desert. There you can go for camel ride, wear traditional Arab dresses and apply mehandi. They have traditional pipe for smoking called See-Shaw. Liquor is also supplied and heavy non vegetarian dinner with Barbeque, Kabab and Deserts. The highlight of the event is the famous belly dance for about 30 mins.

Apart from all this places you can see lot of high-end cars. There the minimum speed ois 80 km/hr. Even i experienced a speed of 180km/hr and cars overtaking our car in that speed. All together it was a pleasant experience.
