I write here about research data science, reproducibility, and the tools I build and use. Posts range from technical walkthroughs to more reflective pieces about the work itself.

Reproducibility by design with toolero
r
reproducibility
coding

Code drift — the quiet divergence between what you report and what you actually ran — is one of reproducibility’s most common and least visible failure modes. This post introduces a workflow built on three toolero functions that address drift structurally: a scaffold that doubles as a maintained source, a context-detection utility that replaces informal path patches, and a post-render hook that derives the submission script automatically.
