Chartfold: Owning Your Medical Records

I have cancer. My oncologist is at one hospital system (Siteman/BJC), my primary care doctor at another, and my earlier treatment history lives at a third (Anderson, where my first oncologist practiced). Patient portals are fine for browsing, but …

Code Without Purpose

Time is finite in ways I can’t ignore. That changes which questions about code feel important.

I read a post arguing that the most valuable programming skill in 2026 is deleting code. The thesis: AI generates code faster than anyone can review …

Masked Failure Data: Looking Back, Looking Forward

I have been working on the same statistical problem since 2020. I am now a PhD student in CS. The problem has not changed, but my understanding of it has, and the tools I have built around it look nothing like what I started with.

The problem: a …

dapple: Terminal Graphics, Composed

I live in the terminal. Most of my tools are CLIs. When I want to see something visual (an image, a plot, a table of results), I do not want to leave the terminal to see it.

Terminal graphics tools exist, but they are fragmented. One library does …

Posthumous: A Federated Dead Man's Switch

Some things should only happen after you can’t do them yourself.

Posthumous is a self-hosted dead man’s switch. You check in periodically (via phone, browser, CLI, or API call) and if you stop, it progresses through escalating stages …

Observation Functors: Composable Censoring for Series System Simulation

Last week I announced maskedcauses, the R package for estimating component reliability from masked series system failures. That post covered the three likelihood models and the path to CRAN.

This post is about what happened next: the package now …

pagevault: Hiding an Encryption Platform Inside HTML

HTML is an encryption container format. That sounds wrong, but think about what an HTML file can hold: arbitrary data in script tags or data attributes, a full programming runtime via JavaScript, and a rendering engine (the browser) on every device …

maskedcauses: Maximum Likelihood Estimation for Masked Series System Failures

Note (February 2026): This package has been renamed from likelihood.model.series.md to maskedcauses.

Two days ago, I submitted likelihood.model to CRAN, the foundation package for composable statistical inference. Next in line: maskedcauses, which …
