Actually Useful Stack Traces in Action

Here ↑ I debug the faulty program using stack traces. I also highlight the weakness and limitations of usual text-based representation and show the alternative implementation we made for Ares/Arei IDE.

The demo of the Actually Useful Stack Traces implementation is at 8:14. And of course, don't forget to check out the accompanying blog post.

As a bonus at the end I explain why the stack traces in mainstream programming languages are upside down and why we do the other way around.
