Unlocking Ractors: class instance variables in Ruby (byroot.github.io)
In a previous post about ractors, I explained why I think it’s really unlikely you’d ever be able to run an entire application inside a ractor, but that they could still be situationally very useful to move CPU-bound work out of the main thread, and to unlock some parallel algorithm.

Rust's Sneaky Deadlock With `if let` Blocks (bearblog.dev)
Rust is my favorite programming language. I've been writing Rust for about 6 years, from college to professionally, and I'm vocal about how helpful the compiler is in catching particularly nasty multithreaded issues and memory bugs. What the compiler doesn't always catch though is deadlocks, which can occur using several well known types like Mutex and RwLock.

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.
