More code

I've now got a source code management system (Mercurial / TortoiseHg) running on my desktop and home machines, and have successfully pushed code around. I've learned a bit more about Google App Engine, and put together the first of many demos to help illustrate capabilities with some real world examples, which might even become the canonical ones if I'm very, very fortunate.

Here is a simple guestbook which allows you to overwrite a previous entry if you happen to have the token (a random number) associated with it. The jargon for such a key is a capability, to make things easy, I put them out there for all to see and abuse.

If you wish to replace an entry, copy the token from it and enter it below your new text.
