    Episode 12 - Neil Mitchell on Development Tools

    Neil Mitchell shares with us his enthusiasm for building development tools. We hear the story of how he built Hoogle in order to learn Haskell, why he created the Shake build system and what he hopes to accomplish with it, and how he uses hlint in his own development work. We discuss Haskell IDEs (including his own minimal ghcid) and briefly touch on a variety of other development tools and libraries that aim to improve Haskell development. Neil also shares a trick he uses for hunting and fixing space leaks in programs and libraries.

    Episode 11 - Austin Seipp on Security

    Austin Seipp joins us to discuss Haskell security and infrastructure. We talk about how Haskell security differs from C (and where it doesn’t) and some coming changes to Cabal security. Then we discuss Cryptol: a Haskell-inspired language for implementing cryptographic algorithms in a way that more closely resembles their mathematical specification. Finally, we talk a bit about his work in maintaining the haskell.org infrastructure and his time as a GHC release manager. Along the way, Austin shares about his pet projects, including hardware projects using CλaSH.

    Episode 10 - Bryan O'Sullivan on Performance and Efficiency

    Bryan O’Sullivan shares his experience helping make developers more efficient, both inside of Facebook as Director of Developer Efficiency and with his various Haskell libraries, some of which you probably know and use already: aeson, attoparsec, criterion, statistics, and text (to name a few). We speak about performance and optimization of Haskell programs and where documentation for “Real World” Haskell development should go from here. Talking with Bryan also reveals how far you can go with Haskell without being overly concerned about category theory and the other math behind the language and libraries.

    Episode 9 - Conal Elliott on FRP and Denotational Design

    Conal Elliott, inventor of Functional Reactive Programming, tells us about the birth of FRP as well as other stories from his 30+ years of functional programming experience. He shares what he considers the fundamentals of FRP (behaviors and events) and how they work in a model with continuous time. We speak about FRP practicality and efficiency, including how a continuous time model can help lead to a high performance implementation. Eventually we’re led into Denotational Design, which plays a part in the design and refinement of FRP and which Conal considers his simplest and clearest design tool.

    Episode 8 - Ollie Charles on 24 Days of Hackage and Nix

    Ollie Charles, author of 24 Days of Hackage (and a number of Haskell libraries), gives us his perspectives on Haskell libraries and how they relate to Perl’s CPAN. He shares how he began his transition from Perl to Haskell while working for MusicBrainz and how he came to work full-time on Haskell at Fynder. (Listen closely if you’ve wanted to write Haskell in your non-Haskell job.) We also chat briefly about developing in Haskell with Nix and a different take on equational reasoning.

    Episode 7 - Chris Done on Compiling to JavaScript and SQL

    Chris Done, creator of Fay, Try Haskell, and Structured Haskell Mode, chats with us about web development in Haskell. We start with compiling Haskell to JavaScript via Fay, Haste, and ghcjs. We then discuss SQL and the alternatives available. Finally, we speak briefly about shell scripting and Haskell. Other topics include Chris’s many side projects like Try Haskell and Hulk, his IRC server.
