Public Speaking Blog…
Sense I find myself in front of people more and more often I have decided to start a public speaking blog. Just writting down stuff I learned in college public speaking class. Hopefully someone will find it useful:

I just received a call from unknown after a very long and annoying message it directed me to the following website: http://www.cashtolive.com which then led me through a bunch of videos and at the end it said would you like to meet the inviter that invited you when I said yes it listed the following information:
Name: Steve W
Phone: 404.502.9298
Just so that Google will index this page so that other people can find this information.
Edit: They called again but this time it was from this number:
Phone: 213.426.1018
Check out my friends new web site.
Here is some code I wrote in the not to distant past.
Has to be with plotting primes on polar coords. Some interesting results appear.
