I am kinda feeling like durable execution is going to be a very boring thing that's tablestakes at some point in the next N years (where N < 5).

hey @schickling.dev if I use @livestore.dev as an event-sourcing framework, am I locked into using SQLite as the event store or is this swappable?

Need to take a closer look but @livestore.dev can be used as an “event-sourcing framework”

Just ran `bun index.ts` without installing node_modules first and amazed that it *just worked*. Then found out about auto-install. Nice feature @bun.sh!

“very few customers… are going to ask Amazon for Paxos-as-a-service... AWS should return to its roots and release important building blocks — the things customers will need, not necessarily what they're asking for”
