   Hey I'm the maintainer docker-mac-net-connect. Just an update that the issues caused by the latest Docker desktop changes have been fixed in the latest version. The battle with Docker Desktop is a bit frustrating and likely ongoing, bu

    Supabase engineer here. This was a lot of fun to build with the Electric team. There were a lot of technical hurdles to jump over - I’m happy to cover any questions. We’ll continue shipping throughout the week. I see a lot of feedback in th
