The wind is blowing against us.....IIT me summer intern. karne nikla ek laphanga aur ek nihayati sharif banda....dono ka mission ek and ITS UNACCOMPLISHED...yaha aake mile ek choti wale baba se (our project guide).. A g_y(fill as per ur wish -a/u) with MS from UK and 100 papers to his name....hai bara hi chat...
LINUX aur OCTAVE ka salesman and we r the customer. ham dono ka jina haram karke rakha hai.....but i am impresed with the development out here...an institute with 24hrs net,8 hostel(each with 500 rooms),supercomputer managing the server(PARAM 2000),quality food...next year the first batch of IIT patna as well as the electrical depp. will kick of here...with the magnitude of research here...truly its a institute providing a global degree...

ok...enough of techicallity......
...The day was tuesday(24th june)..i boarded the 7:30p.m. bus to take me back from city to the campus...i saw an assemese girl sitting just infront of me...keeping patience and control over my body(means mouth) was getting tough...inspired by the tacniques followed by my yar..Rohit and Bed ..i took a deep breath and asked her whether she know someone called "mamon sakia"(i cooked that name)..her reply was obviosly "no"..but to keep that track going...i requested her to think again...then she asked me "what's is ur friend's branch"..straightway i said "EE"..she smiled for a long while........and smiled...... now when i am blogging my first...i know the reason..and we both r laughing like never before here at iit....(MISSION UNACCOMPLISHED)
