This site is running in 11ty and is built locally, after which the live site (which gets built into the _site folder) is pushed to my Reclaim Hosting account, where it's served up as kfitz.info.

This post describes an issue I’ve had with writing correct types when using PEP-696 defaults in typing.TypeVar. I posted the exploration in a companion repository on GitHub. The motivation behind this comes from my work in biomedical data integration and the semantic web.
Repurposed Appalachia Series Being perched between 4,100 and 4,223 feet on the rugged spine of Stone Mountain, the modern High Knob Observation Tower greets each sunrise with a gleam of galvanized steel on sandstone. Long before it became a scenic waypoint for motorists and hikers near Norton, Virginia, High Knob’s summit served an urgent purpose: keeping watch for wildfire.
Introduction When we exercise, our hearts run faster, which is associated with a decrease in the time between heartbeats. This time between heartbeats is also known by R-R intervals. If you have ever seen an electrocardiogram (EKG) curve before, each time your heart pumps you’ll see a small spike in your EKG;
