Today, 2025-03-12, at 1930 UTC (12:30 pm PST, 3:30 pm EST, 7:30 pm GMT, 20:30 CET, …) we are streaming the 40th episode of the Haskell Unfolder live on YouTube.

The Haskell Unfolder Episode 40: understanding through a model

QuickCheck is useful for more than just testing. Comparing the behaviour of a system to a model can be used to check if a system under construction is working correctly, but it can also be used to better understand an already existing system. In this episode we show that this does not need to be very difficult, by designing a model that we can use to understand tensor convolutions in an existing large library.

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.
