renfield 25.9.23

Hapless and flawed servant of the not1mm contest logger.

renfield

Danger

• There is currently no need to look at this.
• No need to download this.
• Certainly do not run this.

This will be the Not1MM contest data aggregation server.

Currently it is just just a bunch of sadness.

Recent Changes

• [Epoch] And then there was light.

The Idea

Renfield is an amateur radio contest contact aggregation server for Not1MM. It uses Textual for rendering the interface. This provides the user with either a CLI or a web interface depending on how it is launched.

The client(s) Not1MM and the server Renfield talk to each other over a UDP Multicast network connection. There is no file sharing or network file access. The Not1MM clients and Renfield each maintain their own database. As contacts are made they are stored in Not1MM's local database. That record is marked 'Dirty' and a UDP message is sent out. Once Renfield gets the message and saves it's copy, Renfield sends a response message to confirm. The Not1MM client gets the confirmation and clears the 'Dirty' flag on the record. Not1MM keeps track of the messages it has sent out. If it doesn't get a reply either because Renfield didn't get it or Not1MM didn't get the confirmation message, Not1MM will just retry every 30 seconds until it does. Each contact has a UUID v4 tag to prevent any duplicate records.

If Renfield should crash and burn, or the PC/device it is running on should catch fire. You can spin up another instance of Renfield, then have the Not1MM clients mark all their contacts as dirty, and they will re-stream all their contacts to the new server. Eventually I'll make that reciprocal. Where if a Not1MM client were to fail, it will be able to ask Renfield to send all it's contacts back.
