@tsyum I think they might be using ActivityPub through Peertube instead of Mastodon?(For new folks: Peertube is the equivalent of Youtube except unlike Youtube it's able to connect to anything that uses the ActivityPub protocol, like Mastodon.

Dr. Gladys West, Mathematician Whose Work Made GPS Possible, Dies at 95In 1956, West began working as a mathematician at the Naval Surface Warfare Center in Dahlgren, Virginia.
