UPDATE: I'm working on a new book: Practical Machine Learning with H2O, again with O'Reilly. Should be out in the Autumn. If you want me to let you know as soon as it comes out (and get a discount code!), send me an email (address is below).

I'm director at QQ Trends, a company that solves difficult data and software challenges for our clients. (We often have freelance projects, so get in touch if interested.)

My book, "Data Push Apps with HTML5 SSE" is out and selling! Get it from O'Reilly here: http://shop.oreilly.com/product/0636920030928.do Or from Amazon here: http://www.amazon.com/dp/1449371930 Or from any good bookseller.

UPDATE: looking for another part-time CSS/JS programmer. 理想は東京所在、日本語が読める方。Interesting project(s), you will definitely learn something.

(And, of course, please do get in touch if you have interesting challenges that you would like our world-class experts to work on!)

Typical work: doing fun stuff with data (fixing, mining, etc.), web sites (front and back-ends), trading strategies. Research: trading strategies, computer go, machine translation, understanding context, AI search algorithms. Languages: C++, PHP, R, javascript, and many more.

I'm British, living and working in Tokyo for almost 20 years. Human Languages: English, Japanese (fairly fluent, 1 kyu), some German, Chinese and Arabic.

(Contact me at dc at qqtrend dot com: please mention you are coming from StackOverflow, so I know it is not spam.)

Easy ways to irritate me on StackExchange sites (whether my own question or someone else's): 1. Downvote without a comment (N/A if someone already left a comment and you just agree with it, of course); 2. Answer in comments. Other than that I'm a really easy-going and pragmatic guy :-)
