Hacker News with Generative AI: Asynchronous Programming

Playground Wisdom: Threads Beat Async/Await (pocoo.org)
It's been a few years since I wrote about my challenges with async/await-based systems and how they just seem to not support back pressure well. A few years later, I do not think that this problem has subsided much, but my thinking and understanding have perhaps evolved a bit. I'm now convinced that async/await is, in fact, a bad abstraction for most languages, and we should be aiming for something better instead and that I believe to be thread.

Blocking code is a leaky abstraction (notgull.net)
Asynchronous code does not require the rest of your code to be asynchronous. I can’t say the same for blocking code.

Show HN: Bringing multithreading to Python's async event loop (github.com/NeilBotelho)
This is an attempt at building an asyncio compatible event loop that is multithreaded. I.e. you will finally be able to use asyncio and actually have it be multithreaded ! I've written a blog post explaining more about the why and how of this project.

Automatic async to sync code conversion (psycopg.org)
Psycopg 3 provides both a sync and an async Python interface: for each object used to perform I/O operations, such as Connection, Cursor, there is an async counterpart: AsyncConnection, AsyncCursor, with an intuitive interface: just add the right async or await keyword where needed:

Waiting on many things at once with io_uring (mazzo.li)
When doing systems programming we often need to wait for something to happen. Common examples might be waiting for some data to come through a socket or waiting on a lock. We also often want to wait on any of several conditions to become true. A web server might be handling many sockets at once, waiting for any number of them to become readable or writeable.
