The Making of a Forecasting Bot

I recently published my acx book review contest 2024 submission on Savage Money. My 2023 submission last year was a review of War and Peace.

The missiles appeared to hit some places in London more than others (train tracks?), and the British government was worried the Germans were somehow able to target the missiles effectively.

In the future correlations article we will learn the following transformation of the correlation coefficient33 The logit function captures the idea that a difference in correlation between 0.95 and 0.98 is more difficult to prove than e.g. a difference between 0.2 and 0.3.:

Looking through the articles I’ve started but never finished, I stumbled over a cool experiment from a few years ago: When a build in a ci environment fails, it usually does so quicker than the time required for a full, successful build. This means we ought to be able to find the fraction of failed builds from the build times alone.11 Don’t ask when this would be useful. I don’t remember.

Achilleas has a trick where they use curl under hyperfine to do basic benchmarking of web performance. Even if we dislike the methodology, we may be curious what it looks like. However, we may not want to install hyperfine globally on our system just for this one experiment.
