 h1. 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: 

 # 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 
 # 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]]). Right now there is no permanent location yet, but you can get recordings at . They can also be found on 

 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). 

 h2. Timing 

 [usually] *Friday evening, 8pm CET/CEST, every 2nd and 4th friday of the month* 

 The next couple of events hence are: 
 * Friday, January 28, 2022 
 * Friday, February 11, 2022 
 * Friday, February 25, 2022 

 h2. 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 

 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.
