Entry 1237

On Scripting News today, Dave announced that NewsIsFree supports the Cloud element of RSS 0.92. This is neat, I never totally understood how this worked before, until I read his longer description.

Basically, the way I understand it... in your RSS you have a "cloud" element that has address of a server in it which accepts HTTP-POST, XML-RPC or SOAP messages. If you want to, you send a message to the cloud server saying "Let me know when there's an update". Then every time there's an update that server will notify the client that there has been a change. Really elegant distributed stuff.

Here's a longer description of the cloud interface. Good, I was wondering when the notification expires. It expires after 25 hours, so if you ever decide to stop supporting notification you can just say "No" and give a message to explain next time anyone tries to register with the cloud. I'm impressed.

Oh, here are some good points as to why this scheme won't scale.
