This site is now shut down. When I created it, I wrote:
It's hosted on App Engine and without a domain name so it doesn't require any money to keep running and minimizes risks of it shutting down due to lack of funds or forgotten domain name renewals.I wanted to write code once and have it work forever. Well, what I didn't anticipate is that App Engine would require occasional maintenance on the project owner's behalf, to update to changes in App Engine. I have no interest in doing that. Sorry.
