This is the story about how I wondered if I could get pydantic logfire to work in a SQL cell in marimo. I got it to work, thanks to a PEP 249 from 1999.

I wrote a tutorial on integrating DBOS with Logfire. It's super easy to set up (kudos to the @pydantic.dev team!) -> just a few lines to configure the exporter and your Logfire write token. Once it's running, you'll get a unified view of your app with logs + traces in one place.

New starter project just landed in @logfire.pydantic.dev
Uses pydantic.run to let you send data to logfire without leaving your browser.
(and yes, I deleted that write token before posting this 😉)

I mean, obviously there'd have to be a REST server, otherwise how would you get any data out of the experiment? You gotta log what the agent generates and wrap a basic UI around it.
Hm. Maybe it's time to learn about Logfire. That always looked cool.
I wonder how cheap I can get away with this.

Debugging is fun, like solving a puzzle, especially with multiple dependencies involved. Today I first thought there was a bug in DBOS, then suspected Logfire, and finally pinpointed the issue to the OpenTelemetry Django instrumentor.

Hey, I'm struggling (and I don't mean this sarcastic or anything like that) to understand why I should move to logfire. Could you explain (or point to some docs) how logfire distinguishes itself from the established solutions provided by Grafana/elastic/sentry?

I've been meaning to play around w/ sqlite fts5, turso, pydantic logfire, and flyio for a while.
Finally, found the time to write this simple key-value manager bot for an internal telegram chat while leveraging all of these.
