About the Author
Arun Manivannan has been an engineer in various multinational companies, tier-1
nancial institutions, and start-ups, primarily focusing on developing distributed applications
that manage and mine data. His languages of choice are Scala and Java, but he also meddles
around with various others for kicks. He blogs at http://rerun.me.
Arun holds a master's degree in software engineering from the National University of Singapore.
He also holds degrees in commerce, computer applications, and HR management. His interests
and education could probably be a good dataset for clustering.
I am deeply indebted to my dad, Manivannan, who taught me the value of
persistence, hard work and determination in life, and my mom, Arockiamary,
without whose prayers and boundless love I'd be nothing. I could never try to
pay them back. No words can do justice to thank my loving wife, Daisy. Her
humongous faith in me and her support and patience make me believe in
lifelong miracles. She simply made me the man I am today.
I can't nish without thanking my 6-year old son, Jason, for hiding his
disappointment in me as I sat in front of the keyboard all the time. In your
smiles and hugs, I derive the purpose of my life.
I would like to specially thank Abhilash, Rajesh, and Mohan, who proved that
hard times reveal true friends.
It would be a crime not to thank my VCRC friends for being a constant
source of inspiration. I am proud to be a part of the bunch.
Also, I sincerely thank the truly awesome reviewers and editors at Packt
Publishing. Without their guidance and feedback, this book would have
never gotten its current shape. I sincerely apologize for all the typos and
errors that could have crept in.
