Not satisfied with implementing one of the most popular automated theorem provers, Z3, Leo de Moura also tackles another extremely hard problem in our field and implements a brand new interactive theorem prover from scratch, Lean. In this episode we dive into the mind and philosophy of this man. Links Leo’s Website Lean Z3 The Church of Logic Podcast

In this episode we continue our conversation with Jan de Muijnck-Hughes a Research Associate at Glasgow University. He works using all sorts of fancy type systems mostly targeted for hardware specification, particularly with the aid of the theorem prover Idris. This episode we start by talking a little about Impostor Syndrome in academia and how he has learned to cope with it and then we dive deeper into the technicalities of his research, in particular his philosophy on Type Directed Design of Systems. We talk about Session Types, Graded Types, Quantitative types, etc. Don’t forget to join our new discord channel! If you like our show please consider donating any amount at ko-fi.

In this episode we have a deep conversation with Jan de Muijnck-Hughes, talks about all the cool research he has done with idris, hardware and different kinds of interesting type systems such as session types, quantitative types and graded types. In the second half we discuss all the different kinds of problems that has been going on in PL academia lately and what we can do as a community to address those issues.

In this episode we have over Dan Plyukhin, a PhD Candidate from the University of Illinois Urbana-Champaign. We talk about Dan’s research is in the field of parallelism, more specifically garbage collection in the presence of actors. Then we also talk about Pedro’s research on translating GADTs from OCaml to Coq, and the burnout process that lead him to take 10 months off from his PhD to be with his family back in Brazil.

Jimmy Koppel, got his PhD at MIT and found the Mirdin Company, where he teaches engineers to write better code! In this interview we talk about how to make better code, how the knowledge of computer science theory and programming languages can help engineers to achieve that, and much more!

In this episode we host another company that does formal method in the context of the Everscale Blockchain, and Solidity smart contracts. How and why they use formal methods in this context? Who are their clients? What are the caveats? Links Pruvendo’s Website Pruvendo’s Linkdin Pruvendo’s Twitter

In this episode talk with Gerwin Klein about the formal verification of the microkernel seL4 which was done using Isabelle at NICTA / Data61 in Australia. We also talk a little about his PhD Project veryfing a piece of the Java Virtual Machine. Links Gerwin’s Twitter Gerwin’s Website ProofCraft’s Website

Kevin Buzzard has been very passionate spreading the word among mathematicians to use theorem provers mechanize theorems of modern mathematics. In this conversation we will talk about his vision in teaching undergrads to use the Lean theorem prover, what is the Xena Project, his view of how theorem provers can change the way we do mathematics, and much more!

In this episode we partner with Formal Land, a company that works in formally verifying the Tezos codebase! I have worked with them in the past developing new features to their source-to-source compiler CoqOfOcaml. In this episode we talk about their work with Tezos and how their techniques are applicable to other codebases as well! For this we talk with Formal Land founder Guillaume Claret and the proof engineers Daniel Hilst and Pierre Vial.

In this episode we interview Lawrence Paulson, one of the creating fathers of Isabelle. We talk about the development process, how it drew inspirations and ideas from LCF and Boyer Moore. What tools were used, it’s strenghts and weaknesses, and all about the historical context at the time! We also briefly talk about his formalization of the Gödel’s Incompletenes theorems in Isabelle Paulson have quite an extensive CV, he is a professor at Cambridge, have published more than 100 papers, is an ACM fellow since 2008, is a member of the royal society since 2017, among many other things!
