You describe the workflow you want, and the agent builds it 100% unit tested on top of the generic DSL and workflow engine

v1.118 rolls out today!

New in this update: You can now translate posts without leaving the app.

Simply tap "translate" on mobile and your phone's built-in translation takes it from there.

Does anyone have a favourite book on the history of nuclear weapons? I'm particularly interested in how the physicists grappled with the ethics of what they were unleashing on the world. I fear computer scientists might be the next to have such a reckoning.

I'm going to start announcing things related to node-postgres here instead of on twitter/x. I will potentially post more about node-postgres in general here but at least the major announcements should all be here, not there. Sunsetting the x account.

You know how for many movie "franchises" only the first movie is any good, like for Jurassic Park and for Alien?

The main exception is Star Wars, for which none of the movies are good.

Announcing npmx: a fast, modern browser for the npm registry Today we're releasing the alpha of npmx.dev – a fast, modern browser for the npm registry, built in the open by a growing community.

npmx is now in alpha: this is our story, as told by our team and friends

It's such a powerful idea. At the end of every Claude session you analyze the event log to look for process optimization opportunities.

You know the event log is reliable because you build your state from it.

Can also build some simple UIs for visualising what happened as well

Initial draft: github.com/NTCoding/aut...

I'm wondering if it would make sense to use the event storage for notes. So that when we spawn new team members, they can read the event history to get upto speed.

Claude Code workflows as DSL-driven domain models - Nick Tune Evolving the hook-driven workflow engine into a proper domain model, each state declaratively defined in a single DSL-driven file.

New post: Claude Code workflows as DSL-driven domain models

I was bored, so I developed the ideas in my previous blog post and I kind of like where all of this is heading.

Pro-tip: workflow as a stream of events and you've got an audit log that you can feed back to AI to improve on.
