Welcome to the blog archive.

I’m proud to have been a blogger since 2006, when I started Casting Out Nines on the Blogger platform to write about teaching innovations and issues in higher education. Blogging built my writing and speaking practice and introduced me to the power of one person with a platform to accomplish a lot of good. Two decades later I am still at it, putting out sometimes half-baked but always whole-hearted commentary and attempted insights on a full spectrum of topics and issues.

My blogging has moved around a lot, and in 2024, I decided to move all of my blogging activity to Substack. This left a lot of old posts in an orphaned state, so on this page I have archived most of my old posts going all the way back to the early days. There’s a lot here, so I encourage you to use the search bar below to look for particulars.

Please note: Images, math notation, and code blocks almost universally don’t work in these archived posts. I’m afraid I have no intention of fixing those. Sorry!
