I wrote a harness leveraging tmux and nvim: https://github.com/wb14123/tcode . It's able to open subagents and even talk with them, all managed by tmux and using nvim as the UI for both the editor and the messages display window.
Yeah I'm also wondering that. I'm looking for self-host PostgreSQL after Cockroach changed their free tier license but found the HA part of PostgreSQL is really lacking. I tested Patroni which seems to be a popular choice but found some pretty critical problems (https://www.binwang.me/2024-12-02-PostgreSQL-High-Availabili...). I tried to explore some other solutions, but found out the lack of a high level design really makes the HA for PostgreSQL really hard if not impossible. For example, without the necessary information in WAL, it's hard to enforce primary node even with an external Raft/Paxos coordinator. I wrote some of them down in this blog (https://www.binwang.me/2025-08-13-Why-Consensus-Shortcuts-Fa...) especially in the section "Highly Available PostgreSQL Cluster" and "Quorum".
My theory of why Postgres is still getting the hype is either people don't know the problem, or it's acceptable on some level. I've worked in a team that maintains the in house database cluster (even though we were using MySQL instead of PostgreSQL) and the HA story was pretty bad. But there were engineers manually recover the data lost and resolve data conflicts, either from the recovery of incident or from customer tickets. So I guess that's one way of doing business.
Instead of giving up the good guarantee of etcd, a better approach maybe grouping some nodes together to create a tree like structure with sub clusters.
I don't see lots of AR/VR techs in the intro: there is no interaction with real world, there is no 3D object other than virtual screen and virtual controls. It seems to be just a traditional portable computer with bigger screens. I can see the potential of it. But at the current stage, it's hard to justify the price.
