    Interesting that you've removed all Prolog. I seem to be hearing about a lot of use of Datalog in program analysis circles: any thoughts on that?

      Yes, Prolog and Datalog and DCG are great tools in metaprogramming. I just figured that I might get a bit more readers by more consistently relying on Haskell throughout. This nice side effect is that I now have many problems coded up both in Prolog and Haskell. Don't get anywhere interestingly deep into program analysis.

Lecture series on advanced (functional) programming concepts

[ Added 10 Aug 2010: Here is the link to the first lecture's video: " The Expression Problem ". ] If you are a programming nerd or something of a similar species, you may know of C9 Lectures at http://channel9.msdn.com/tags/C9+Lectures . Several of the lectures are given by Erik Meijer who has turned many chapters of Graham Hutton 's book " Programming in Haskell " into videos. In my recent, recorded lecture on " Programming Paradigms and Formal Semantics ", I also incorporated Graham's text, but you should really watch Erik's lectures, if you haven't---they are more fun. I am inspired by his ability to present relatively simple content in such a crisp, insightful, and enjoyable manner. In the aforementioned lecture, I covered all kinds of "crazy stuff" though, and in the end, I had to deliver body bags to my Bachelor students---in the form of a radically simple examination. Thanks a lot btw to @grammarware for helping with t...

Software Engineering Teaching Meets LLMs

Software Engineering Teaching Meets LLMs Context: On 2023-05-26 I attended the  VERSEN  event  SEN Classrooms (26 May 2023) . (What is VERSEN? I quote from the VERSEN website: VERSEN is " the Dutch National Association for Software Engineering. Its mission is to bring together researchers, educators and practitioners in the field of software engineering ") (I haven't been in Utrecht in a while. It was great to be back. I love the campus and the science park.) My keynote presentation had the title " Software Engineering Career Planning in the Age of AGI+/- ". My slides are available here: [ .pdf ] Loads of relevant content is linked on those slides, but there is probably not much ROI from the slides alone. I want to call out though my DOs and the DON'Ts for teaching adaptation in software engineering. SE Teaching Adaptation — DON’Ts   Don’t ban the use of AI. Don’t ignore the new role of AI. Don’t grade homework likely done by LLM. Don’t aim at outsmarting th...

A tiny proof checker in Prolog

The Prolog code for this post is available on GitHub . I am crazy enough to teach Hoare logic (axiomatic semantics) in the first course for our CS students. For instance, consider the following program (in some simple imperative language), which is supposed to compute quotient q and remainder r according to Euclidian division for operands  x and y : q = 0; r = x; while (r >= y) { r = r - y; q = q + 1; } Given natural numbers x and y , the postcondition of the program is this: x == q*y + r && q >= 0 && r>=0 && r < y The precondition is this is: x >= 0 && y > 0 We are supposed to prove the "triple" consisting of precondition, program, and postcondition. Let's face it, verification according to Hoare logic is not easily understood by beginners. Many of my students aren't mathematically / logically fit, when they enter the curriculum. So it is a pain in the neck for them to listen and for ...
