Today, 2024-11-20, at 1930 UTC (11:30 am PST, 2:30 pm EST, 7:30 pm GMT, 20:30 CET, …) we are streaming the 36th episode of the Haskell Unfolder live on YouTube.

The Haskell Unfolder Episode 36: concurrency and the FFI

There are two primary ways to import C functions in Haskell: “unsafe” and “safe”. We will first briefly recap what this means: unsafe functions are fast but cannot call back into Haskell, safe functions are much slower but can. As we will see in this episode, however, there are many more differences between unsafe and safe functions, especially in a concurrent setting. In particular, safe functions are not always safer!

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.
