A retired prof who tries to get some research in before cycling with the bunch at dawn. I like my work to surprise people, but am now so radical that few believe me, even though all theorems in my second book “Tree Calculus” are formally verified.
Am I arrogant? It's too soon to tell!
Counting the real numbers in tree calculus
Type inference is hard but don't hack the terms, just the types: the correct link is
Oops! Will fix in half-an-hour

The semantics-syntax distinction is just code for the mind-body problem

Logic engineers truth.
If you are going to POPL 2025 in Denver consider coming to my talk at #PEPM2025 on the missing diagonal.
The computing community has produced many high level languages and tools for programming high level systems (e.g. Java for user interfaces)

Calculus or Calculi? at GitHub.com/barry-jay-personal/blog/2024-12-12-calculus-calculi.md explains why there are now two versions of tree calculus in play, and that’s ok
Since some people find my writing too dense, I’ve written a blog “Turning Poetry into Prose” to expand on my new paper “Typed Program Analysis without Encodings” that shows how to type my tree calculus. The blog, paper and book are all at GitHub.com/barry-jay-personal/
Right! You can also check out my book “Reflective Programs in Tree Calculus” and a type theory for it “Typed Program Analysis without Encodings” at GitHub.com/barry-jay-personal
So, this is cool:
treecalcul.us
A very simple intensional calculus. A simple, privileged programming language where functions can be analyzed, serialized, etc.
The interesting meaning of “blatant” is “open and shameless”. Since “blatant” is degraded, perhaps we just use “open and shameless” instead, or “shameless” where “open” is understood.

My paper “Typed Program Analysis without Encodings” has been accepted for PEPM (a satellite meeting of POPL) in Denver in January. It shows how to type tree calculus, including its self-interpreters. If you’re going I’d be happy to meet up!
