I'm a software developer, I live in Dublin, and I work for Amazon.com. Everything I say here is my own and my own fault and not theirs.
Ruby, Python, Javascript, Objective-C, Rails, Django, Shoes (and anything written by _why) are all interesting and fun and I use them wherever I can.
Sometimes I use Java, but lets not spoil the mood.
This site is actually a very small Rails application which smashes together some very pleasant HTML from Matthew James Taylor and the Ruby implementation of Mark Pilgrim's very fine Universal Feed Parser.
Linux is neat, OpenBSD shows what software can be when you're trying. I own more Apple products than I can remember buying.
