Curious and motivated

It was fun to solve challenges while I was free in my early days at Coriolis Technologies

  • Persistent RAM: This was very interesting. Maintain the state of portion of RAM even after a reboot, without having to dump on persistent storage!
    One senior fellow in my previous company did this for Solaris - I studied from his techniques and implemented the same on Linux kernel over a period of 2 weekends
  • Spice for Android: Aakash Android tablets were developed by Indian Institute of Technology and were offered at subsidized price to students. I wanted to get Spice client running on these tablets so that one could easily access machines hosted using Colama. I worked on an old opensource Spice client and updated it to get it running on recent versions of Android

Personal Projects

I'm a programmer first. Most of my projects are open source, they are available at my Github. I also like to contribute to open source projects when I get time.

  • delve - Golang debugger

    I added support for multiple file / directory tables for multiple compilation units. This enabled the debugger to work with CGO codebase

  • flyway - database migrations manager

    added support for non-transactional SQL migrations. I patched their code in a single day to unblock my then employer, justwatch.com This patch enabled updating ENUM types in the postgresql database.

some of my hobby projects

HNotepad - Notepad using Haskell!

  • Functional programming and specifically Haskell is my long lost love, and I'm always hoping to catchup with it in future.
  • Building anything, even as simple as a Notepad is fun when it's Haskell :-)
  • HNotepad

Online Communities

I learned to code only because of awesome internet communities.
During my graduation, which I did in Commerce, I had no formal education of computer science or programming.
Its because of internet communities I got to learn something new everyday, I could explore the new technologies and develop a wide skillset.

  • chip-india.com
    • Since 2005, I was active on the forums hosted by a tech magazine called Chip at chip-india.com. (This site is now closed down.)
      Most important thing I learned from this forum was, how to use 'teh interwebs' to get most out of it.
      This knowledge and some awesome online friends is what I owe to chip-india.com
