Want to work with me at the $DAYJOB?
I am the CEO of OmniTI where I do all sorts of stuff I find absolutely fascinating.
Writing
I spent a few years writing down my thoughts about how one should approach problems. If you're looking for a how-to guide, a cookbook, or a reference this book is not for you. If you want to learn by challenging the way you think, pick up a copy.
Hacking
It is rumored that I write code sometimes. I often don't believe this myself, so I use this to follow what it is that I'm working on:
