Unfortunately, I managed to delete my WordPress database at a time when the most recent backup I had was from 11 years ago.
So… I will hopefully get some newer information uploaded again sometime.
But, most of my content is gone. 🙁
Scott Burson pointed out that The Wayback Machine has my content: http://web.archive.org/web/20240901104727/https://nklein.com/
And, Daniel Brooks pointed out that NewsBlur has the stuff from my RSS feeds: https://www.newsblur.com/site/101509/nklein-software
I will eventually get to moving some of that back here properly.
