Haskell Weekly

Special guest Marco Sampellegrini talks with us about his recent book, The Simple Haskell Handbook. The book describes a project driven approach to Haskell development, using a continuous integration server as a motivating example.

Should you organize modules vertically or horizontally? This week we take a look at another article by Gabriella Gonzalez, this time about organizing projects and packages.

How can you avoid deeply nested error handling code? This week we review Gabriella Gonzalez's trick for keeping error handling flat.

Curious about the Haskell Foundation? This week we interview Andrew Boardman, its Executive Director. He explains the Foundation's purpose and how you can help.

What happens to exceptions when you don't explicitly handle them? This week we review Taylor's blog post about default exception handlers.

Special guest Cody Goodman walks us through an interesting PostgreSQL bug. Handling async exceptions properly is trickier than you might expect!

Byte string, text, and vector, oh my! This week we review Michael Snoyman's proposal to unify vector-like types. Learn about boxed versus unboxed values, pinned versus unpinned memory, and more.

Special guests Michael Litchard and Brian Hurt talk with us about their new social networking site Chat Wisely. We hear about their experience using Haskell not only on the backend but also on the frontend through GHCJS.

Special guest Sandy Maguire talks with us about using Haskell Wingman for program synthesis, designing bulletproof abstractions with algebra, wrangling type level programming in Haskell, and managing effects with his Polysemy library.

Linear types finally landed in GHC 9.0.1! We talk through what that means along with other news from the Haskell Foundation and Tweag.
