I hope that someone out there finds this site interesting. Items posted here are not tutorials - but feel free to use them as such if you wish. I have tried to remain informal (assuming that most visitors won't be mathematicians) but have tried to keep my language precise and mathematically correct. In every case I explain what I'm doing so that any careful reader will be able to follow the logic if not the math.

What is not on this site...

Any of the code I have written for clients.

Any of my ideas for websites, implementations of technologies and anything that is valued intellectual property. You may do whatever you wish with any of the code, etc.

If you have any questions about this site or things posted here please feel free to contact me.
