Making sense of asyncio

When in doubt you should use asyncio when you can and threading when you must.

Async Python is not faster

It's indeed slower than "sync" python under a realistic benchmark. A bigger worry is that async frameworks go a bit wobbly under load.

Use Go Channels as Promises and Async/Await

If you’ve ever programmed with Javascript, you definitely know about Promise and async/await. But what about Golang?

Understanding Rust futures by going way too deep 🦀

The text is a deep dive into understanding Rust futures. It starts by setting up a basic Rust project and adding dependencies like tokio, color-eyre, and tracing. It then demonstrates how to make a simple HTTP request using the reqwest library. The author explains that futures in Rust are just state machines that don't do anything until they are polled, which is demonstrated through creating a "dumb future". The text then dives deeper into the internals of Rust futures, showing how to inspect the call stack when things go wrong, even using unsafe code to cause a segmentation fault. The overall message is that Rust futures are powerful but require understanding their underlying mechanics to use them effectively.
