Today, 2024-10-16, at 1830 UTC (11:30 am PDT, 2:30 pm EDT, 7:30 pm BST, 20:30 CEST, …) we are streaming the 34th episode of the Haskell Unfolder live on YouTube.
The Haskell Unfolder Episode 34: you already understand monads
Function composition is the idea that we can take two functions and create a new function, which applies the two functions one after the other. When viewed from the right angle, monads generalize this idea from functions to programs: construct new programs by running other programs one after the other. In this episode we make this simple idea precise. We will also see what the monad laws look like in this setting, and we will discuss an example of what goes wrong when the monad laws are broken.
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.
