The tokio::io::AsyncRead documentation confusingly states:

Poll::Ready(Ok(())) means that data was immediately read and placed into the output buffer. The amount of data read can be determined by the increase in the length of the slice returned by ReadBuf::filled. If the difference is 0, EOF has been reached.

https://docs.rs/tokio/latest/tokio/io/trait.AsyncRead.html

The footgun is that when poll_read is called, buf may already be partially filled. In some cases, this happens just a small fraction of the time in production, causing e.g. the last chunk of a file to be poll_read twice.

I noticed the same thing that you noticed with Twitter shaping mind-wandering thoughts, and that makes me think one of Twitter's wide effects is to rob tens of millions of people of paragraph-sized thoughts. Posting a large paragraph with multiple tweets feels imposing, and writing something complicated and nuanced on Twitter can also feel odd. Courageous people bend the medium to their will, but the medium largely demands informal and aphoristic thoughts. And as you say, that then shapes our MW time.

I really like the first Dostoevsky quote and “contemplation”. Mind-wandering may set someone free if their non-MW activities are keeping them stuck in some bad local maximum.

The arguments against the perceptual-decoupling view are really interesting and seem right, though I'm not familiar with the research being critiqued. It's funny that they would miss these counterexamples.

MW as a result of flexible relations to goals is interesting. I noticed that while reading and underslept, I kept MW as I had a goal

"""Patch The Witness stair movement and bypass its startup corruption guard.

The movement patch rescales a player-only walk-manifold request when traversal adds
vertical displacement. The startup patch removes the conditional jump that routes
a zero critical-asset sentinel to ``fatal_error_data_corruption``. The PE file size
and section count remain unchanged.
