Rubysyn: Clarifying Ruby’s Syntax and Semantics
[WIP, 2026-04-01] This is an experiment in clarifying some aspects of Ruby syntax and semantics. For that we’re going to introduce an alternative Lisp-based syntax for Ruby, preserving Ruby semantics. The goal is to define a comprehensive, trivially-parsable and sugar-free syntax. As I started working on this, I had to find a better explanation for […]

And one of the most promising new approaches to come out of the academy is the “sociology of literature”—the study […]
Improving my focus by giving up my big monitor
