Having totally fouled up the back end of this blog, I am now in the process of restoring it after a complete from-scratch reinstall. Arrgh.

I think I have fixed most of the big stuff, but please don’t be surprised if there are some glitches over the next few days. In particular, I lost a bunch of comments (157, to be precise) that I have yet to figure out how to restore. Also, I’m still restoring pictures and graphs to some posts.

Please bear with me.
