In this episode, Niki and Andres talk with Sebastian, one of the main developers of Lean, currently working at the Lean Focused Research Organization. Today we talk about the addictive notion of theorem provers, what is a sweet spot between dependent types and simple programming and how Lean is both a theorem prover and an efficient general purpose programming language. 

In this episode, Wouter and Sam interview Dominic Orchard. Dominic has many roles, including: senior lecturer at the University of Kent, co-director of the Institute of Computing for Climate Science, and bye-fellow of Queen’s College in Cambridge. We will not only discuss his work on Granule - graded monads, coeffects, and linear types - but also his collaboration with actual scientists to improve the languages with which they work.

In this episode, Garrett Morris talks with Wouter Swierstra  and Niki Vazou about his work on Haskell’s type classes, how to fail successfully, and how to construct a set of ponies.

Andres and Sam interview Pepe Iborra, exploring his journey from academia via banking to now Meta. In this episode, we discuss Pepe’s involvement in the evolution of the Haskell ecosystem, in particular the ongoing journey to improve the developer experience via work on debuggers, build systems and IDEs.

Victor Miraldo is interviewed by Niki and Joachim and walks us through this career from a student falling in love with List.foldr through a PhD student using agda to verify cryptographic data structures and generic diff and merge algorithms to a professional developer using Haskell in production. He’ll tell us why the Haskell community is too smart, why there should be a safePerformIO, and that he hopes that Software Engineering could be less like alchemy.

In this episode Tom Sydney is chatting with Matti Paul and Niki Vazou. Tom is the author of many tools, like sydtest, decking, and nix-ci. He tells us about the rules for sustainable Haskell, how Haskell lets one man do the job of 50, and the secret sauce for open source.

Tom Sydney is also looking for work these days, so get in touch!

Wouter and Joachim interview Arseny Seroka, CEO of Serokell. Arseny got into Haskell because of a bet over Pizza, fell for it because it means fewer steps between his soul and his work, and founded Serokell because he could not get a Haskell job. He speaks about the business side of a Haskell company, about the need for more sales and marketing for Haskell itself, and about the Haskell Developer Certification.

In this episode, Andres Löh and Matthías Páll Gissurarson interview José Nuno Oliveira, who has been teaching Haskell for 30 years. José talks about how Haskell is the perfect language to introduce programming to all sorts of audiences, why it is important to start with Haskell, and how the programmers of the future have been learning Haskell for several years already!

Avi Press is interviewed by Joachim Breitner and Andres Löh. Avi is the founder of Scarf, which uses Haskell to analyze how open source software is used. We’ll hear about the kind of shitstorm telemetry can cause, when correctness matters less than fearless refactoring and how that can lead to statically typed Stockholm syndrome.

Roman, known better online as effectfully, is interviewed by Wouter and Joachim. On his path to becoming a Plutus language developer at IOG, he learned English to read Software Foundations,   has encountered many spaceleaks, and used Haskell to prevent robots from killing people.
