people have wildly different interpretations of the same words; it’s honestly amazing that we manage to communicate anything at all with each other

I declare every CPU instruction is now a microservice (because they are really tiny, right?). All computing ceases to be possible, and the world heals.

Typeclasses are OOP

Our paper Multi-Stage Programming with Splice Variables, co-authored with Ningning Xie, has been accepted to ICFP'25 😀! We designed a language for flexible, type-safe code generation, with advanced features like code pattern matching — enabled by what we call splice variables.

Another award that is announced at PLDI is the SIGPLAN Programming Languages Software Award. This year, the award was received by the LEAN theorem prover (Lean), which has had and continues to have broad impact on mathematics, hardware and software verification, and AI!

I wrote a short blog post "The Interplay Between Metaprogramming and Computation in Lean": chrishenson.net/posts/2025-06-…

I am looking for a PhD student to join us in Tallinn!

My article on the "Formalization of derived categories in Lean/mathlib" is the first article afm.episciences.org/15978 in the first volume of the brand new journal Annals of Formalized Mathematics.

The first volume of the new Open Access journal "Annals of Formalized Mathematics" was released today! ➡️afm.episciences.org/volume/view/id… #FormalMath #Mathematics #OpenAccess

Itai Sher what definition of "AI tool" are you using here

Tangentially related, but I think this is why Lean's typed metaprogramming system, while wonderful, is such a burden to learn. After a couple of years I still learn new functions every time I ask for help on the Zulip, and in contrast there aren't really primitives you can inline

I've been trying to make this exact decision. Does anyone have experience with Framework laptops? After getting burned on unreliable System 76 hardware, I'm hesitant towards going for a newer company. For considering a modern Thinkpad, I was leaning towards the upper end P series
