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. It is not everything I’ve ever done, just some things I want to highlight.

Notes:

I’ve included articles, tutorials, and projects.
I also have a talks & workshops page with… talks and workshops.
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.
