New Website

Sun, 31 Aug 2025 00:00:00 +0000

After 25 years (yikes!) of hand-coding HTML for my personal website, I ported the content using the Hugo static site generator and the hugo-xmin theme. Thank you Yihui Xie for the template.

I went with Hugo because that is what the Apache Parquet site uses, and I didn’t have any other ideas.
