thoughts!

After living in the beautiful campus of the Indian Institute of Technology,Guwahati for more almost 430 days and experiencing the subtle variations of the weather, I have realized that I have lived some of the best moments of my life. The area just outside the campus is called Amingaon. Its so green. If you will walk down the road, you will feel that u are somewhere in kerala.The mighty Brahmaputra is always there to accompany you. The ashwaklanta mandir, the ferry ghat, the doul gobind mandir and of course the brahmaputra bridge are some of the places I often visit when I don’t feel like doing anything, when I don’t like feel like thinking anything…just to be with myself……IIT has been a good experience…first, to be with some of the best brains in the country…the geeks….nerds…..students are so free and independent…so open-minded….crazy to fulfill their passion and at the same time trying to handle the tough academic curricula…and they do it successfully…the system ensures that once you pass out, you are robust enough, tough enough to do anything and everything….producing the real engineers…who are capable to solve real life problems…..the other day, I was chatting with my guide and he told me…and I quote..”see, we are engineers and not mathematicians…hats off to them how they think…give big big theorems…prove them….i mean they are genius…we cannot think like them…we should work application specific….we don’t work on assumptions…we should think practically….we should be aware of the constraints that we are going to face while implementing something….” It was indeed a thoughtful thought….i pondered over it…in the mind, I had a flashback of whatever I had done in the project till date and I realized that if I go for the implementation, I will have “n” number of issues to tackle….so I decided that I should first find out what are the constraints….what is the ground reality…

I will tell you something about my project…..it is tilted”authenticating encryted data”….there is tremendous and overwhelming flow of information in the digital world…..this information needs to be protected....from whom? From pircay….for having secured communication…for making the communication secured, you need to present the information in way that is non-sense for unintended destinations….only the guy for whom you are sending the message is able to decode it….this is called as encryption….encyption scrambles the information, removes the correlation among the data points…

We are aware of the fact that bandwidth needs to be properly utilized. When, we deal with multimedia data like images, audio, video ..we actually deal with a large heap of information…it needs to be properly represented so that the storage and bandwidth requirements are reduced….compression gives us the solution…..compression looks for the correlation….looks for the pattern in the data and tries to remove the redundancy…..

And, here is the conflict…..compression looks for patterns….encryption tries to remove it….so, the first issue to be tackled is to have an encryption algorithm which preserves the compression ratio to some extent…..

Authenticating means to prove that I am original, I have originated from the true source…I have not been manipulated….here, I represents information….industry standards that are used are watermarks, hash functions, message authentication codes….in my project, I have to incorporate watermarks/hash with encryption so that the watermark remains invariant to the encryption process…..thats the second issue to be tackled….

Project has been a great learning experience….sometimes you don’t know what you are doing…where are you heading….there are moments that when you come to know that the lines you were thinking on was wrong…..you have to rethink, reorganize yourself….

At times, the final year of m.tech seems boring….no course work…only teaching assistantship duty…so going to the lab is not mandatory(thanks to my guide for being so flexible with me)….there are times when I feel blank….all alone….i so eagelry wait for the clock to hit 6 p.m. when the sun sets(the scorching sun I must say)….and I just flee away from my room into the ground…..i try to find someone to play with…badmintion..tennis or cricket…when there is no hang out with, I run….and run…and run….theni come back…drink one litre of milk….my hostelmates call me milk boy!!

Final year has been gracious enough to give me time to read some books…..books are the greatest companions….”To the last bullet” written by Vinita kamte, the wife of late Ashok kamte introduced a great personality….his life style, work ethics will surely have an everlasting effect on my life…presently reading”three statesmen: gokhle,gandhi and nehru”…trying to get into the history….trying to see how that world looked….how those visionaries affected the future of this country….how they shaped up our lives…..i think that the solutions to the problems lie in our past…unless we don’t know it correctly, we wont be able to appreciate and understand why things are like that? Gokhale once told and I quote…”we will never be able to unite hindus and muslims completely”…..i found it so true….

Also reading…”The world since 1945”….there is so much diversity across the nations…I always thought why countries are in conflict….now I realize, why they have so much less conflict!!economic imbalance, power concentration, arms race,neo-colonialism…these issues are taking the world towards more disorder….chaos…we need leadership…..leaders who can guide people…..

Seeing so much problems…so much diversity, I realize the importance of gandhi….what he tried to do….we have to accept the fact that difference will always be there at different levels….at community level, at caste level, at state level, at nation level….people have found unique tools to divide themselves in groups….groups which have common agenda……I will give tell you what I have experienced in my hostel in the last one year….the division between north and south people is so strong…they wont talk with each other….in the mess, they wont sit with each other….there is always a conflict on the mess menu….now leave this aside…once you enter south, there is again division…keralites will be together..telgu will be together……other day, I was talking to one of my friend and my classmate too on the very same issue of why there is such a division….he told that when we sit with north people on the table, they talk in hindi and we hardly understand anything….northern people say they talk in telgu and we don’t understand anything…they shud learn hindi…but the same question andhrites can also raise that why you don’t learn telgu…..and the poblems persists…. ..when the biggest assest of the country fight on such petty issues, I feel bad….acceptance, tolerance, presevearence have been the highlighting point of indian culture…have we lost it? Question haunts but the adventure to find the answer excites….and the excitement increases my belief that gandhi will make a better india…

Hey sachin..its always great to read you all on this blog..
you've been quite a contributer lately..:)
i was just reading through it and thouht i'd say a few things on your writing style..
i felt that our writing style is quite similar in the way you become personal with the issues and express the anecdotes..
But one suggestion..you should be punctuating it better.and differentiation in the parts should be better..
i know its a one go write-up but i have wasted a lot of time putting thoughts in unrecognizable shapes..so thought i shud just tell you..:)

and about your Gandhian philosophy..i think a lot of us should sit together someday to hear about it..
take care..
