The Haskell Interlude

On this episode of the Haskell Interlude, Andres Löh and Mike Sperber are joined by Farhad Mehta, a professor at OST Rapperswil, and one of the organizers of ZuriHac. Fahrad tells us about formal methods, building tunnels, the importance of education, and the complicated relationship between academia and industry.

In this episode Wouter Swiestra and Niki Vazou talk with Conal Elliott. Conal discusses doing things just for the poetry, how most programs miss their purpose, and the simplest way to ask a question. Conal is currently working on a book about his ideas and actively looking for partners. 

Sam Lindley is a Reader in Programming Languages Design and Implementation at the University of Edinburgh. In this episode, he tells us how difficult naming is, the different kinds of effect systems and handlers, languages *much* purer than Haskell, and Modal logic.

Tom Ellis works at Groq, using Haskell to compile AI models to specialized hardware.  In this episode, we talk about stability of both GHC and Haskell libraries, effects, and strictness, and the premise of functional programming: make invalid states and invalid *laziness* unrepresentable! 

Sam and Wouter interview Harry Goldstein, a researcher in property-based testing who works in PL, SE, and HCI. In this episode, we reflect on random generators, the find-a-friend model, interdisciplinary research, and how to have impact beyond your own research community.

In this episode, Matti and Sam traveled to the International Conference on Functional Programming (ICFP 2024) in Milan, Italy, and recorded snippets with various participants, including keynote speakers, Haskell legends, and organizers.

Gabriele Keller, professor at Utrecht University, is interviewed by Andres and Joachim. We follow her journey through the world as well as programming languages, learn why Haskell is the best environment for embedding languages and how the desire to implement parallel programming sparked the development of type families in Haskell and that teaching functional programming works better with graphics.

Today on the Haskell Interlude, Matti and Sam are joined by Satnam Singh. Satnam has been a lecturer at Glasgow, and Software Engineer at Google, Meta, and now Groq. He talks about convincing people to use Haskell, laying out circuits and why community matters.PS: After the recording, it was important to Satnam to clarify that his advise to “not be afraid to loose your job” was specially meant to encourage to quit jobs that are not good for you, if possible, but he acknowledges that unfortunately not everybody can afford that risk.

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.
