This website is for app support as well as math and actuarial items I find interesting.
  • The Apps pages provide a summary of, and links to, some apps I have written for Apple iPhone/iPad and Android devices.
  • The Math pages are pretty limited, but show some mathematics I find interesting. I added a page discussing a variety of poker played at the local recreation center and the frequencies of various high and low poker hands. I had not seen this poker variation discussed anywhere else.
  • The Actuarial pages have some brief information on population and longevity trends in the US.
  • I have a small blog at with comments about books I've read and movies I've seen.
  • A short geometry problem below.
