Writing and Reviewing Jupyter Notebooks
A recent project involves delivering a finished product as a collection of Jupyter Notebooks. This process involves using Emacs for writing, Git for version control, and a slightly tricky process for enabling non-Jupyter, non-Emacs users to perform document review.

Pattern Matching and Tail Recursion in Emacs Lisp
Functional programming offers a bunch of really cool programming patterns. Two that I really enjoy are tail recursion and pattern matching, especially how they are implemented in OCaml. However, I spend a lot of time writing Emacs Lisp now, and I was wondering if I could find a way to use these patterns in that language.

Typing Chinuk Wawa in Emacs
Back in 2015, I took a course in being an ally for local Native American communities from the Portland Underground Grad School (PUGS). One suggested action was learning the local language, but it proved difficult to find opportunities. When the pandemic forced school closures, though, Lane Community College began offering classes online. I found out about this thanks to the Kaltash Wawa blog, and this fall I signed up to take a remote Chinuk Wawa class through Lane Community College.
