Was history ! :)

This blog represents a part of my undergraduate life when I was extremely active. The blog contains about 59 posts and excluding the previous one all the others were written in a span of 6 months ranging from Jan 2008 - June 2008. Which just tells how active I was in those days, and these were times when the Wi-Fi at campus was still in the planning phase and I was using internet over my GPRS enabled ancient Nokia 7610 (using wvdial + rfcomm over bluetooth). So it used to take like 10 minutes to update a post once written. But still never after that period have I written so much. Feels good to think about the intense work I did during the second year which looks simple now, but played an integral role in making me what I am today (if I am something !) !.
