OsmoDevCall¶

As OsmoDevCon could not be hosted in 2020 nor in 2021 due to the Corona virus outbreak, we started hosting an Osmo com Dev eloper Call format of online meetings within the Osmocom community (originally discussed in #4928).

The formant serves two major purposes:

1. technical presentations about osmocom 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 (like the presentations of our prior OsmoCon / OsmoDevCon). The recordings can be found in several formats at https://downloads.osmocom.org/videos/osmodevcall/ . They can also be found on https://media.ccc.de/c/osmodevcall

Not every OsmoDevCall would necessarily need the two parts, but I think it would be great if we can make that happen. We could also have e.g. a two-weekly schedule for the USSE and a monthly schedule for the technical presentation.

We'd need somebody to volunteer to "manage" the "broadcast" side of this, preferably somebody with at least some prior exposure to online events (like the c3voc).

Timing¶

Wednesday evening, 8pm CET/CEST, every 3rd Wednesday of the month

The next few events hence are:

• Wednesday, September 20th, 2023 (Themyscira Wireless: a case study in interconnecting an Osmocom GSM network to USA PSTN)
• Wednesday, October 18th, 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/OsmoDevCall

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.
