Picture Me CodingGleaming the Lambda Cube with Nathan MullThis week Nathan Mull, a type theorist and CS Professor at Boston University, came on the show to help Mike and Erik understand what the phrase "Propositions as Types" is all about. This is an idea about how programs are connected to logic and mathematical proofs, whether we want them to be or not! You know that program that orders pizza from Dominos?! Yes, even that program is a proof of something. Find out what it proves on this episode of Picture Me Coding!LinksNathan Mull's personal site 2014 Philip Wadler Paper: Propositions as Ty...

Future of CodingPropositions as Types by Philip WadlerThe subject of this episode's paper — Propositions as Types by Philip Wadler — is one of those grand ideas that makes you want to go stargazing. To stare out into space and just disassociate from your body and become one with the heavens. Everything — life, space, time, existence — all of it is a joke! A cosmic ribbing delivered by the laws of the universe or some higher power or, perhaps, higher order. Humanity waited two thousand years, from the time of the ancient Greeks through until the 1930s, for a means to answer questions of calculability, when three suddenly arrived all at on...

2022-12-301h 00Future of CodingStructure of a Programming Language Revolution by Richard P. GabrielToday we're discussing the so-called "incommensurability" paper: The Structure of a Programming Language Revolution by Richard P. Gabriel. In the pre-show, Jimmy demands that Ivan come right out and explain himself, and so he does, to a certain extent at least. In the post-show, Jimmy draws such a thick line between programming and philosophy that it wouldn't even look out of place on Groucho Marx's face. Next episode, we will be covering the Worse is Better family of thought products, so take 15 minutes to read these three absolute bangers if you'd like to be ahead...

Iowa Type Theory CommuteOn the paper "The Girard-Reynolds Isomorphism" by Philip WadlerI give a brief glimpse at Phil Wadler's important paper "The Girard-Reynolds Isomorphism", which is quite relevant for Relational Type Theory as it shows that relational semantics for the usual type for Church-encoded natural numbers implies induction. RelTT uses a generalization of these ideas to derive induction for any positive type family.
2021-01-1810 minIowa Type Theory CommuteEquivalence of inductive and parametric naturals in RelTTI talk through a proof I just completed that the type of relationally inductive naturals and the type of parametric naturals are equivalent. This is similar to proofs one can find in a paper of Philip Wadler's titled "The Girard-Reynolds Isomorphism", which I plan to discuss in the next episode.

Functional programmers have long claimed that languages such as Haskell and O'Caml allow one to write code more quickly and more reliably. Widespread uptake of functional programming among the financial community supports that claim, and this talk will examine a few cases.

CoRecursive: Coding StoriesTech Talk: Big Ball Of MudTech Talks are in-depth technical discussions. Evolving software under constrained resources is a challenge, and I think we kid ourselves when we don't admit this. Software that is providing value often grows in scope until it is a mess. Today I talk to Wade Waldron about how avoid this situation or recover from it. Big ball of mud is the title of a paper presented at the 1997 Patterns Languages of Programs conference and I think it is super interesting. The researchers went out into the field to see what architectures software in industry w...

2018-10-291h 21CoRecursive: Coding StoriesTech Talk: God's Programming Language - Philip Wadler on HaskellTech Talks are in-depth technical discussions. Today I talk to Professor Philip Wadler, a very accomplished programming language researcher. Phil walks us through a principle that has guided his career. That principle is that typed lambda calculus is not invented but a discovery of a deep truth. It is something connected to the mathematical underpinning of the universe itself. It follows from this that functional programming languages are therefore more correct or more deeply justified and fundamental than other languages. I am probably stating things in a stronger fashion than Phil is comfortable with, but I l...

International Conference on Functional Programming 2017Theorems for Free for Free: Parametricity, With and Without TypesAmal Ahmed (Northeastern University, USA) gives the first talk in the fourth panel, Integrating Static and Dynamic Typing, on the 3rd day of the ICFP conference. Co-written by Dustin Jamner (Northeastern University, USA), Jeremy G. Siek (Indiana University, USA), Philip Wadler (University of Edinburgh, UK).
The polymorphic blame calculus integrates static typing, including universal types, with dynamic typing. The primary challenge with this integration is preserving parametricity: even dynamically-typed code should satisfy it once it has been cast to a universal type. Ahmed et al. (2011) employ runtime type generation in the polymorphic blame calculus to preserve parametricity, but a proof...

Co-written by Atsushi Igarashi (Kyoto University, Japan), Vasco Vasconcelos (University of Lisbon, Portugal), Philip Wadler (University of Edinburgh, UK).
Session types are a rich type discipline, based on linear types, that lift the sort of safety claims that come with type systems to communications. However, web-based applications and micro services are often written in a mix of languages, with type disciplines in a spectrum between static and dynamic typing. Gradual session types address this mixed...
