Wadler's Blog

I'm looking forward to speaking in Lisbon. 

On June 4, Professor Philip Wadler will give an INESC-ID Distinguished Lecture organized in the scope of the BIG ERA Chair Project, titled “(Programming Languages) in Agda = Programming (Languages in Agda)”.

Registration: here (free but mandatory)
Date: June 4, 2024
Time: 15h00-16h15
Where: Anfiteatro Abreu Faro – Complexo Interdisciplinar, Instituto Superior Técnico (Alameda) 

Abstract: The most profound connection between logic and computation is a pun. The doctrine of Propositions as Types asserts that propositions correspond to types, proofs to programs, and simplification of proofs to evaluation of programs. Proof by induction is just programming by recursion.  Finding a proof becomes as fun as hacking a program. Dependently-typed programming languages, such as Agda, exploit this pun. This talk introduces *Programming Language Foundations in Agda*, a textbook that doubles as an executable Agda script—and also explains the role Agda plays in IOG’s Cardano cryptocurrency.

I am delighted to have made this list. Lesley Lamport and John Reynolds also appear on it, but at positions lower than mine, and Tony Hoare and Robin Milner don't appear at all---so perhaps their methodology needs work.

Congratulations on being named an inaugural Highly Ranked Scholar by ScholarGPS

Dear Dr. Wadler,

ScholarGPS celebrates Highly Ranked Scholars™ for their exceptional performance in various Fields, Disciplines, and Specialties. Your prolific publication record, the high impact of your work, and the outstanding quality of your scholarly contributions have placed you in the top 0.05% of all scholars worldwide.

I'll be appearing at the Fringe in the Cabaret of Dangerous Ideas, 12.20-13.20 Monday 5 August and 12.20-13.20 Saturday 17 August, at Stand 5. The 5 August show is joint with Matthew Knight of the National Museums of Scotland, the 17 August show is all mine. Both shows are hosted by comedian Susan Morrison.

You can book either via the Fringe or via the Stand. If one is sold out, try the other.

Here's the brief summary:

Chatbots like ChatGPT and Google's Gemini dominate the news. But the answers they give are, literally, bullshit. Historically, artificial intelligence has two strands. One is machine learning, which powers ChatGPT and art-bots like Midjourney, and which threatens to steal the work of writers and artists and put some of us out of work. The other is the 2,000-year-old discipline of logic. Professor Philip Wadler (The University of Edinburgh) takes you on a tour of the risks and promises of these two strands, and explores how they may work better together.

I'm looking forward to the audience interaction. Everyone should laugh and learn something. Do come!

I'm looking forward to Lambda Days 2024 and catching up with friends in Krakow.
