Phoenix R&D is working on decentralized MLS and have built a prototype with OpenMLS.
I said it before and I'll say it again: I need to get more familiar with puncturable cryptography primitives (e.g. PPRFs).

Good #rust question. I find this question is something that people used to OOP often skip over and jump directly to the OOP answer and try to shoe-horn that into rust. This usually fails fast.
Time for another stupid rust question. #aurora_rust
So, in my program I have a structs which are called Tasks, there are certain types of those Tasks that I am making such as "Oneclick", "Ontime", etc.
How do I put all of them in one vector so that I can store them in one place?

For local-first I feel like we should shift more focus towards making p2p networks more approachable. Pretty much how web servers became a "solved problem".
And the reason why most devs from the field don't focus on it is: "local-first apps" are still mostly client-server.
