Hi folks, excited to share that I just posted an introductory presentation on Crystal’s concurrency 🎉

We talk about CSP, (a simplified version of) Crystal’s execution model, buffered channels and correctness in concurrent applications.

I’ve been working on this presentation for a while, and no matter the rework, I am still not sure I nailed the order and the way in which concepts are introduced. So, If you have any feedback to make this talk “conference-ready”, I’d love to hear from you 📢
