The Mystery of the Unknown Error

Unhandled exception! Uncaught error!

We’ve all seen them. Developers can’t prevent them. Users can’t avoid them. But with a little detective work, we can actually provide useful information even when we don’t know exactly what went wrong.

In this talk, we will discuss the mechanism of fallback messages for uncaught errors, learn methods to classify uncaught errors, and use the process of elimination to avoid giving users bad advice. We’ll also practice imagining all possible error scenarios for a feature so we can try to avoid these uncaught errors in the future.
