RetroNetCall

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

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 (winter) / CEST (summer), every 1st Wednesday of the month

The next couple of events hence are:

  • Wednesday, June 5th, 2024
  • Wednesday, July 3rd, 2024

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.

Video Recordings of talks

The recording of the technical presentation are made available. The recordings can be found
