Strange Calculus

We build the small software nobody else was going to build.

Each one started as a problem I had — in a van, in a box of negatives, in an on-call rotation — that nothing on the market was going to solve, because the market had decided it was too small to be worth solving. It was not.

Strange Calculus is Casey Bisson.

Every one of these exists because something refused to answer.

A Victron system measures everything and concludes nothing: 64% is unremarkable at four in the afternoon and a bad sign at nine in the morning, and the readout does not know which one you are looking at. A Grafana dashboard already holds the queries that would settle the alert that just paged you, and at three in the morning nobody runs them. A negative was shot somewhere, on some date, through some lens, and the scanner threw all of it away.

The information existed in every one of those cases. What was missing was a judgement — and somewhere along the way the industry decided that shipping a readout counts as shipping a product. It does not. A measurement is not an answer, and handing you a graph is handing the work back.

So these compare against your own history and tell you which it is. That is also why none of them puts a server in the middle: the baseline is your normal, your negatives, your week. It cannot be computed by anyone who does not already have your life in front of them, and it should not be sent anywhere so that it can be. The privacy policy is short because it is a consequence, not a position.

There is no roadmap behind this list. One life: a van, a backlog of scanned negatives, an on-call rotation, and the people and the cat who live around all of it. The reference is always yours because it was always mine first.
