One can also grab a random arXiv paper in HTML (via ar5iv), if that was desired.

Just visit:

https://ar5iv.labs.arxiv.org/feeling_lucky

Is the code for the "feeling lucky" selection mechanism open? Or, do you know how they select papers at random?

[dginev]

Sure, the repository is open source (linked from the front page).

The selection did not get much thought at all, just a Rust rand shuffle over all ids performed at first page visit and then cached: https://docs.rs/rand/latest/rand/seq/trait.SliceRandom.html#...

I had all IDs already computed for the previous/next article navigation feature, so it seemed fun to reuse them.

Thanks for this! If I knew this existed, I wouldn't have built the page myself.
