P.S. Paying to apply may sound provocative and require thoughtful consideration and careful testing. But here, I focus on why price signals may address this problem better than AI-based screening.

Then I asked myself what this solution has that AI doesn't. That’s how I arrived at the analogy that prices act as model weights: they encode market information. An important difference: prices incorporate signals from dispersed, hard-to-observe data that an AI/ML model may not access.

In NotebookLM, the output language is global. A per-notebook setting would be much more convenient

As a non-native English speaker, I don’t want YouTube auto-translating titles, chapters, and descriptions; I want the originals

In statistics, answering a wrong question is sometimes called a Type III error. I've already mentioned it in a blog post: e10v.me/ranking-two-...

From my personal experience, people often skip steps 1 and 3, which can lead to bad decisions or mediocre solutions.

You probably read this in a statistical or data-analysis context. But I believe the framework applies more broadly.

4. What data do we need to apply the model?
5. What conclusions can we draw after applying the model?

A/A tests are useful for identifying potential issues before conducting the actual A/B test. Treatment simulations are great for power analysis—especially when you need a specific uplift distribution or when an analytical formula doesn’t exist.

@marimo.io is not only a great tool for reproducible and interactive research—it's also perfect for interactive documentation where users can play with examples. You can run them as WASM notebooks entirely in your browser—no local setup needed. I personally love marimo's attention to detail.

Does atom count?

And at least one package from the long tail now also uses Narwhals under-the-hood (tea-tasting)
