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 my intellectual property. If I posted stuff here - go for it. You may do whatever you wish with any of the code, etc. I am a strong supporter of open source!

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