All of the video recordings made at the recent 2018 Osmocom Developer Conference (OsmoDevCon2018) have meanwhile been released.
You can find the recordings at https://media.ccc.de/b/conferences/osmocon/osmodevcon18 with a back-up at this youtube playlist
Please excuse the bad audio quality in the Welcome to OsmoDevCon 2018 talk. We didn't pay attention to the clipping and only resolved it towards the end of that talk. All other videos have proper audio quality.
