I'm the Director of HP Labs in Singapore. By day I manage a team of engineers and scientists who research on how people use cloud computing. By night, I am a Rubyist, a technology enthusiast and masked crusader (not really). I frequently speak at technology-related conferences around the world, mostly on Ruby and cloud computing. I have written 3 books on Ruby and the latest is 'Exploring Everyday Things with R and Ruby' published by O'Reilly Media, and I'm still wondering if I should write a fourth.
