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

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

The next couple of events hence are:

* Wednesday, December 6th, 2023

* Wednesday, January 3rd, 2024

* Wednesday, February 7th, 2024

* Wednesday, March 6th, 2024

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.

h2. Video Recordings of talks

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

* at https://media.ccc.de/c/retronetcall (Video hosting platform of the Chaos Computer Club)
