The Voids of Haskell

Haskell Weekly covers the Haskell progamming language. Listen to professional software developers discuss using functional programming to solve real-world business problems. Each episode uses a conversational two-host format and runs for about 15 minutes.

Please keep on publishing it! Finished all episodes and listening to them again. Highly appreciated, thank you! Hope soon I&#39;ll be better on my coding to submit you some questions :)

Perfect length and well crafted choices

I made this podcast and I think it’s pretty great. Check it out!

Pretty good!
