Wish I could... but I know of it from a previous HN post, where there is some discussion on its purpose.

Still my all time favorite snippet of code.

People who dedicate their lives to studying an industry, can get very good at being able to predict the probability of events in their domain.

These same people are commonly off by orders of magnitude when predicting the magnitude of these same events.

The author of this article won the "Toner Prize for Excellence in National Political Reporting". I'm going to infer from this, that he's better at political reporting, than he is at predicting the future of an entire industry.

And if he is truly convinced of this outcome, he should be shorting the airlines. (I'm gonna guess he hasn't done that).

I grew up with Jeremy Brett's Sherlock Holmes, by far, in my opinion, the most accurate representation of the stories.

Only in my adult life did I read the stories, finding large chunks of the dialog in the TV show being word for word taken from the stories. And when not word for word, the tone and feel of the scenes so well portrayed on screen.

Thank you for this. I lost that CD years ago.

If you can track it down, Hendrix's home recordings are a gem.

Revealing AI is a tool, and like any other tool, its how you use it.

If you use it with the express intent to learn, it is an amazing tool.

If you use it as a crutch, it results in "learning avoidance".

I wish I could remember where I picked up this quote

"Smiley's People" remains one of my favorite shows.

If you track it down, I highly recommend watching it with headphones. The sound design is amazing.

The sound of an empty room being profoundly menacing.

Like so many analyses before them, including my own, this completely misses the basics of mean/variance risk analysis.

We need to know the risk adjusted return, not just the return.

Awhile back I put together a visualization of ext4.
