Ask HN: event loops vs. greenthreading in modern languages (ycombinator.com)
Most explanations I've seen on "async programming" bury the reason why we're doing this in the first place. It's purely to avoid making OS threads wait on I/O in a concurrent application, such as a webserver. So languages or even libraries instead have various ways to switch tasks on a single thread. If OS threads were cheap enough to just spawn one for each request, this wouldn't be a thing.

Ask HN: Who's building on Python NoGIL? (ycombinator.com)
I am interested in knowing the things the community is building specifically taking into account the NoGIL aspect of python. Like is someone building frameworks around using Threads instead of Async?

Async closures in Rust have been stabilized (github.com/rust-lang)
This report proposes the stabilization of #![feature(async_closure)] (RFC 3668). This is a long-awaited feature that increases the expressiveness of the Rust language and fills a pressing gap in the async ecosystem.

Async Django in Production (jonathanadly.com)
We believe async Django is ready for production. In theory, there should be no performance loss when using async Django instead of FastAPI for the same tasks. Django's built-in features greatly simplify and enhance the developer experience. Using async involves some complexity, as the entire code path must be async. In AI workloads, this complexity is often a worthwhile tradeoff.

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.

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.

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.
