Self-owning web services, or services that can survive the death of the inventor

I noticed a new web service today called a Dead man's switch, which dispatches email in the event that you don't respond to periodic "pings" that prove you're still alive.

Decimal vs Double Speed

I write financial applications where I constantly battle the decision to use a double vs using a decimal. All of my math works on numbers with no more than 5 decimal places and are not larger than ~100,000.
