I saw this tweet about @livestore.dev and it made me realize that @schickling.dev built exactly the library I need to make realtime notebooks with modern agentic plumbing. More 📘 below ⬇️

The era of manual software development is coming to a close quickly.
My view on software development has drastically changed. I believe in the future the role of engineers will be to build software factories, not the software itself.

Really shows the power of Effect streams.

🧠 Ever heard of event sourcing?
It’s the idea of storing every change as a series of events — instead of just keeping the current state. Think of it like git, but for your app’s data.

Ditto is probably the most mature sync engine out there used in airlines and other critical environments.
Loved this conversation with Adam who’s the founder of Ditto and previously built Realm.

Really compelling demo by @shykes.bsky.social building a “mini Devin” coding agent in a few lines of code.
Finally made the core idea behind @dagger.io click: a runtime and reusable ecosystem for your builds.
Another key insight: Agents are immutable builds. 🤯

We're kicking off our open source fellowship program by sponsoring @schickling.dev from @livestore.dev
It might seem surprising to sponsor LS as it is a data layer that brings data closer to the UI, traditionally a server's job, and we're a server-first framework.

After 4 years of work, I'm incredibly excited to introduce LiveStore, the next-gen data layer I'm building for Overtone.
It's based on reactive SQLite and has a built-in sync engine. Give it a try - would love your feedback!

When I founded Prisma, my goal was to make databases easy.
Now building @livestore.dev, my goal is to make app data simple.
Easy is great, particularly when getting started. But as an app gets complex, simplicity is more important. (Even more true with AI.)

Investing in good debugging practices is one of the highest leverage things you can do as an engineer. Particularly with more AI tooling and/or code written by AI.
Just to name a few:
- Step debugging (in VSC/Browser)
- Structured logging (aiming for high signal)
- OpenTelemetry

I didn't not expect that building the devtools messaging protocol for @livestore.dev would turn out to be one of the most difficult parts to build.
In order to support reliable and efficient messaging (supporting transferables), I ended up building a local networking protocol called "Webmesh".
