Misc

I have a fly-over idea to decongest Hudson Circle area of Bangalore, but nobody responded when I wrote to them. So I've just stuck it here.
I have created cellphone ring tones for some songs that I felt were melodious for phone calls. I used Audacity software (Linux) to create them.

About

Hi, I'm Deepak. I work as a software engineer for a startup company, Zscaler, in Bangalore. Before joining here, I went for graduate studies at Ohio State University, United States. Prior to that, I worked for Citrix Systems, Bangalore, in the Netscaler product line. I'm an alumnus of PESIT, National College, and National High School, Bangalore.

My interests include technology, books, nature, philosophy, and travel. I read mostly non-fiction, on a wide variety of subjects. Of late, I have developed curiosity in finance, investing and markets.

This site has been in existence since 9 May 2000, in myriad avatars.
