Retronetworking

h1. RetroNetCall

{{>toc}}

Initially we started to cover a couple of retronetworking topics at the [[osmo-dev-con: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:

# 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

# 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.

h2. Timing

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

The next couple of events hence are:

* Wednesday, March 1, 2023 (Introduction to the X.21 Interface)

* Wednesday, April 5, 2023

* Wednesday, May 4, 2023 (E1: The analog side)

* Wednesday, June 7, 2023

h2. Venue / Platform

We are currently using infrastructure of "KNF":https://franken.de/, a German non-profit internet organization of which @laforge is a member.

%{font-size: 20pt; color:red}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.
