Today, 2024-07-03, at 1830 UTC (11:30 am PDT, 2:30 pm EDT, 7:30 pm BST, 20:30 CEST, …) we are streaming the 28th episode of the Haskell Unfolder live on YouTube.
The Haskell Unfolder Episode 28: type families and overlapping instances
In this episode, we discuss a programming technique which allows us to replace overlapping instances with a decision procedure implemented using type families. The result is a bit more verbose, but arguably clearer and more flexible.
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.
