  • Convenience in Haskell: Ergonomics of Cabal by Vance Palacio

    Should we be trying to create some type of wrapper around hpack/cabal that focuses on user experience, avoiding the work of creating a cabal exact-printer, not burdening cabal maintainers with thinking about perfect UX, and leaving cabal alone to be a good packaging tool/power user tool?

  • Episode 35 – Iavor Diatchki by The Haskell Interlude

    Wouter and Niki are joined by Iavor Diatchki to talk about his experience with different Haskell development styles, writing a high assurance wiki in php, and maintaining Haskell code across different GHC releases over multiple decades.

  • Release: stan, extending support to GHC 9.6 by Tom Ellis

    I’m pleased to announce an even newer release of stan, a static analysis tool for Haskell. This release extends last week’s release by adding support for 9.6, extending the supported range to 8.8-9.6.

  • Use traversals for batch operations by Oleg Grenrus

    Often enough we have an API which may (or need) to provide a batch operation: “give me many inputs, and I’ll give you many outputs”.
