selected work samples (mostly writing)

This page has some selected work samples. They’re mostly writing samples, but I’ve also included some tutorials and projects.

Notes:

I’ve included articles, tutorials, and projects.
I also have a talks & workshops page!
The projects section includes programming projects with significant writing content, usually in the README.
Some tutorials have accompanying videos/slides.
Some of these docs are old and refer to things that don’t work anymore. I’ve included approximate publish dates to highlight that context.
