The Haskell Interlude

In this episode Niki Vazou and Mattias Pall chat with Richard Eisenberg. Richard is currently a language designer at Jane Street, he is the chair of the board at the Haskell Foundation and known for his work on the GHC compiler.  Today we talk about dependent types in Haskell, how to get involved with GHC and Haskell foundation and how Haskell and Ocaml are different, for example, functor means a totally different thing in the two languages. 

In this episode Christiaan Baaij is interviewed by Wouter Swierstra and Mattias Páll. Christiaan talks about his work on the Clash compiler, what it is like to found your own company, his desire for ergonomic dependent types, and the foundations to all his success, namely capitalising on luck.

Errata: Around the 21m19s mark Christiaan talks about “his“ contributions to GHC with regards to dynamic linking on OSX. Later he remembered that it was actually Moritz Angermann who [worked on the symbol limit restrictions](https://gitlab.haskell.org/ghc/ghc/-/commit/b592bd98ff25730bbe3c13d6f62a427df8c78e28). However, Christiaan did [some other work on OSX linking](https://gitlab.haskell.org/ghc/ghc/-/commit/f7be53ac9dac85b83e7fe5ecede01b98a572ba48) and some of the [RPATH handling](https://github.com/haskell/cabal/pull/2255/commits).

In this episode Simon Marlow talks with Andres Löh and Matthias Pall. Simon is a long time GHC contributor, currently working at Meta. He talks about compiling functional  languages via C and the Evil Mangler, the importance of using parallelism and its impact on garbage collection, and about using Haskell in the real world via Sigma, Haxl, and Glean. 

In this episode Joachim Breitner and Wouter Swierstra talk to Andrew Lelechenko, also known as Bodigrim. Bodigrim went from a being a mathematician to a failed PHP developer the chair of the Core Libraries Committee. In this episode, we discuss whether he prefers number theory or Haskell, whether he prefers working with compilers or PHP frameworks, and whether he prefers high salaries for Haskell developers or breaking changes to the base library

In this episode Andres Löh and Niki Vazou chat with Jeremy Gibbons. Jeremy Gibbons is professor at Oxford and talks about his journey from Orwell to Haskell, how to teach Haskell and specification languages to undergraduates as well as professional programmers, how programming languages should keep simple things simple, and how paper writing can or even should be like poetry.

In this episode Wouter Swierstra and Joachim Breitner chat with Ben Gamari. Ben is a consultant at well-typed known for his work at GHC. Ben tells us a little bit about his switch from Python to Haskell but not because he was missing the static typing, how programming his thermostat lead him to a career in the compiler development, and what it's like to be a GHC force multiplier. 

In this episode Andres Löh and Niki Vazou talk with Alejandro Russo.  Alejandro is a professor at Chalmers University in Gothenburg Sweden, he is an enthusiastic functional programmer as well as a researcher in the fields of security and privacy. He talks about the unique strengths Haskell has in these areas and how to move research ideas into industry. 

In this episode Matthías Páll and Andres Löh  talk with Andrey Mokhov. 
Andrey is best known for his work on the Hadrian build system and today he talks about algebraic graphs, selective functors, and the  difference between OCaml and Haskell. 

In this episode Jesper Cockx, one of the main Agda developers, is interviews by Niki Vazou and Matthias Pall. They talk about how to explain dependent types to one's father, how Agda’s automation and proof search work, and how Agda can be used to verify Haskell code bases.

In this episode Marc Scholten is interviewed by Andres Löh and Joachim Breitner. They talk about the Integrated Haskell Platform web framework (IHP), implicit parameters and nix.
