renfield 25.9.25

Hapless and flawed servant of the not1mm contest logger.

^ I was bored. Kinda reminds me of Sun Microsystems. ^

Danger

This will be the Not1MM contest data aggregation server. It's currently not feature complete.

Recent Changes

• [25.9.25] Got it generating Cabrillo files.

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.

Things that need doing

• Make a stupid logo.
• Discover which contest is being run.
• Handle QSO CRUD operations.
• Show some basic band/qso/point statistics.
• Chat functions (handled by the clients)
• Manage giving out serial numbers.
• Generate a Cabrillo file.
• Reverse feed QSO's back to a client if requested.
• Show Mults.
• Indicate Dupes when queried.
