Initially we started to cover a couple of retronetworking topics at the OsmoDevCall, but it really made sense to run the pure retro related topics as a separate series of events. In October 2022, we forked the Retro Net working Call format from OsmoDevCall.

The format serves two major purposes:

1. technical presentations about retronetworking relevant topics - ideally current/recent developments
   • can be pre-recorded to avoid any problems with technical setup, streaming, ...
   • should ideally have a Q+A session at their initial "airing" during one OsmoDevCall
2. unstructured supplementary social event (USSE)
   • random chat in audio (optionally video)
   • not recorded, obviously

The recording of the technical presentation should then be permanently made available. The recordings can be found in several formats at https://downloads.osmocom.org/videos/retronetcall/ . They can hopefully also soon be found at https://media.ccc.de/c/retronetcall

Not every RetroNetCall would necessarily need the two parts, but I think it would be great if we can make that happen.

Timing¶

Wednesday evening, 8pm CET/CEST, every 1st Wednesday of the month

The next couple of events hence are:

• Wednesday, August 2, 2023 (no topic. Possibly some semi-live reporting on efforts to rescue an EWSD digital exchange)
• Wednesday, September 6, 2023

Venue / Platform¶

We are currently using infrastructure of KNF, a German non-profit internet organization of which laforge is a member.

The URL to join the meeting is https://osmocom.org/RetroNetCall

There currently is no password or authentication, we try to welcome anyone. If this turns out to be a problem, we might lock it down in the future, let's hope that's not required.
