Transcript context

…And it was it was years of maintaining Pydantic and people complaining, hey, that example is out of date now. But eventually we went and built a PyTest example. Which is another the hardest to search for open source project we ever built. Because obviously, as you can imagine, if you search PyTest examples, you get examples of how to use PyTest. But the PyTest examples will basically go through both your code inside your doc strings to look for Python code and through markdown in your docs and extract that code and then run it for you and run linting over it and soon run type checking over it. So and that's how we keep our examples up to date. But now now we have these like hundreds of examples. All of which are runnable and self-contained. Or if they if they refer to the previous example, it's already structured that they have to be able to import the code from the previous example. So why don't we give someone a nice place to just be able to actually run that using OpenAI and see what the output is. Lovely. All right. So that's kind of Pydantic. And the notes here, I just like going through people's X account, not Twitter. So for four years, you've been saying we need a plain text accessor to Jupyter notebooks. Yeah. I think people maybe have gone the other way, which may get even more opinionated, like with X and like all these kind of like notebook companies. Well, yes. So in reply to that, someone replied and said Marimo is that. And sure enough, Marimo is really impressive. And I've subsequently spoken to spoken to the Marimo guys and got to angel invest in their account. I think it's SeedGround. So like Marimo is very cool. It's doing that. And Marimo also notebooks also run in the browser again using Pyodide. In fact, I nearly got there. We didn't build Pydantic.run because we were just going to use Marimo. But my concern was that people would think LogFire was only to be used in notebooks. And I wanted something that like ironically felt more basic, felt more like a terminal so that no one thought it was like just for notebooks. Yeah.…
