I run nihongoresources.com, inkdb.org, and keep pretty much all my code over on github. I worked on and maintained Processing.js (now discontinued), and currently work as senior full stack developer for the Mozilla Foundation -- I also like maths, and am the author of the Primer on Bezier Curves, and enjoy hacking on OpenType font things. I use StackOverflow mainly to help people with JS, Processing/Processing.js, Bezier curve, and OpenType/font questions, but since I've used Java and PHP for ages I'll pitch in on those, too.
