I finally got around to restoring blog posts from 2005-2010 that disappeared in February of this year when the old blog crashed after being damaged by a malicious intruder. The old posts may be found at the old blog address — www.danielharper.org/blog.
There is no longer a redirect on the old address to this blog. Therefore, if you haven’t updated your bookmarks or your RSS reader, or if you’re following an old link, you’ll wind up at the old blog. So please update your bookmarks, etc.
