Today, 2024-07-17, at 1830 UTC (11:30 am PDT, 2:30 pm EDT, 7:30 pm BST, 20:30 CEST, …) we are streaming the 29th episode of the Haskell Unfolder live on YouTube.

The Haskell Unfolder Episode 29: exceptions, annotations and backtraces

Version 9.10 of GHC introduces an extremely useful new feature: exception annotations and automatic exception backtraces. This new feature, four years in the making, can be a life-saver when debugging code and has not received nearly as much attention as it deserves. In this episode of the Haskell Unfolder we therefore give an overview of the changes and discuss how we can take advantage of them.

About the Haskell Unfolder

The Haskell Unfolder is a YouTube series about all things Haskell hosted by Edsko de Vries and Andres Löh, with episodes appearing approximately every two weeks. All episodes are live-streamed, and we try to respond to audience questions. All episodes are also available as recordings afterwards.

We have a GitHub repository with code samples from the episodes.

And we have a public Google calendar (also available as ICal) listing the planned schedule.

There’s now also a web shop where you can buy t-shirts and mugs (and potentially in the future other items) with the Haskell Unfolder logo.
